There are certain times of year when having the central heating on all day is not really necessary (not to mention expensive) but things haven't quite warmed up enough yet to mean you want no heating at all. This is where the best oil-filled radiators really come into their own – a convenient way of keeping warm without sending electricity bills soaring.

I was still of the opinion that oil-filled radiators were somewhat old-fashioned if I'm totally honest – clumsy in their design and slow to heat up. How wrong I was – the ProBreeze OmniWarm 2500W Oil Filled 11 Fins Eco Radiator has totally changed my opinion. Here's why.

In a nutshell

With an RRP of £109.99 and various power settings that mean you can keep running costs down, this contemporary-looking oil-filled radiator is a very smart investment.

While you might not get that instant hot blast that fan heaters offer, this radiator gets up to temperature in minutes and will start distributing its heat nice and evenly throughout the room much faster than you might imagine.

The smart features are a really handy extra that give you an added level of control and don't require any tech wizardry to get to grips with.

Unboxing, setting up and first impressions

The heater came well boxed with only the minimum packaging used to keep it from being damaged in transit. Not all the packaging was recyclable which was a shame. However, on the upside, I had expected it to be far heavier to carry into the house than it was.

In total there were just three main components included – the radiator itself and the two sets of castors, as well as the fixings to attach them. The radiator also comes with a neat little remote, already fitted with its batteries.

The castors were super simple to attach using the wing nuts they came with – no tools necessary. Other than that, the radiator comes ready to plug in and go and, thanks to the concise and easy-to-read instruction manual, I had mine up and running with no dramas.

I had wondered whether smart electric heaters were worth it and given that this was my first time using one (or any kind of smart appliance for that matter!) I was a little worried that setting it all up would be complicated but I was pleasantly surprise. All I needed to do was scan the QR code in the manual to download the ProBreeze app – which then took me through around three simple steps to get connected to my WiFI – et voila, we were good to go. From the app I can control the temperature, turn it on and off and use the timer settings.

Quick word of note, I had a small panic when I checked the app at one point and was told it couldn't connect to the heater. Initially I thought something had gone wrong but then realised this was because the heater had been switched off at the wall rather than being left in standby mode meaning I needed to reconnect.

When you first turn the heater on there is a bit of of a light gurgling and trickling sound as it gets up to temperature – which only seemed to take a minute or two. After that, it is silent to run, unlike some of the other best electric heaters I have tested.

Appearance wise, this is nothing like the bulky old-fashioned oil-filled radiators you'd see in the past. Despite its impressive heat output, this is pleasingly slimline with a far more modern appearance – you definitely wouldn't notice its presence if you located it in a discreet position within your room, although it is recommended that you leave at least 50cm clearance space on all sides.

What’s it like to use?

In short, this is one of the easiest heaters I have used. It has a switch on the side to turn it on at which point the standby and timer buttons light up. To begin using it to heat the room you just press the standby button, using either the panel on the unit or the remote control (or with the app on your phone if you are using it).

It has four modes – ECO, High, Medium and Low. Once you set the temperature the heater operates automatically in ECO mode where it continuously adjusts to keep this temperature stable. Usefully, you can also see the room's ambient temperature if needed.

I found the ECO setting to be perfect – even on a pretty chilly day. It quickly took the edge off the cold in my open plan space and, unlike a fan heater, managed to give out a much broader type of heat that seemed to spread out throughout the area rather than spot heat. I also noticed that even after it was turned off it stayed warm for around 30 minutes, although I imagine this would depend on the temperature you had it set at.

Unlike a fan heater I would feel more confident using the timer on this one, for example setting it to come on a little while before everyone gets up in the morning as a way of heating the house without turning the central hearting on to warm things up a bit or before I am due to get home to avoid walking into the freezing entrance hall (the radiator in here is stubbornly unreliable and using the heater here made the world of difference.)

I am also loving the fact that as we enter that time of year when it is hard to know when to turn the central heating off, this can be used to bridge the gap, allowing you navigate the UK's unreliable spring temperatures easily.

Like I said, the heater is not overly heavy, but the castors it sits on and comfortable handle make it even easier to wheel around the house as much as you want.

One downside – and something I have found with a few heaters I have tested – is that the cable length is not quite as long as I would like. It is 150cm and in my open plan space I would quite like to have been able to position it a little more centrally than was possible. That said, had we bit a little more generous with the number of electrical sockets here it might not have been a problem.

One more thing worth noting, when the heater is switched off, either at the wall or using the power switch, it loses connection to the app. This isn't too problematic – you simply need to reconnect it to the WiFi by holding down the timer button for five seconds.

And finally, if you have young children around, you need to be aware that the metal fins do get quite hot to the touch, as you might imagine – take care with this.

How much does it cost to run?

Using the January 2026 energy price cap figure for electricity, which is 27.69p per kWh, this 2500W heater would cost just under £0.70 per hour to run. In all honestly I expected it to be a bit cheaper.

That said, when those figures drop in April, to 24.67 pence per kWh, the heater's running costs will also come down – to around £0.62 per hour. Also, these calculations are based on using it at full pelt. If you were to run it on its Low setting which is a constant 1000W, it would only cost you 24.67 pence per hour. Given that we are now coming out of winter, that might be all you need.

It is also worth noting, particularly if you are looking to save energy, that even when it has been turned off, the heater continues to give off a little free heat – unlike some of the electric fan heaters out there.

Cleaning and maintenance

As a pristine white heater (black is also available) this is going to readily show up dust and, when my dog came in from a walk and decided to shake nearby it did get splattered with muddy water.

However, cleaning was easy with a soft damp cloth – just make sure you've turned the heater off and let it cool completely before doing this.

Obviously the fins make getting rid of dust a little tricker than it would be with a flat panel heater, but the slimline nozzle attachment on my vacuum took care of this and a manual radiator brush would act in a similar way.

What do other online reviews say?

In general, reviews for the OmniWarm 2500W Oil Filled 11 Fins Eco Radiator Heater are really positive, with users praising its simple set-up and ease-of-use.

A few reviewers online mentioned that they felt the thermostat under-read room temperature, suggesting you might need to adjust it accordingly to avoid it working harder than necessary. Others found WiFi connectivity to be a little unreliable.

Who should buy this electric heater?

This is perfect for all kinds of uses. It would be great for getting an unheated space, such as a garage, workshop, or freezing cold entrance hall like mine, nice and warm quickly.

It is also perfect for those looking for a way to get their home feeling a little warmer on a chilly spring or early-autumn morning when the central heating might not be in use but you need a blast of heat.

Like I said, those with young children should take care with the hot surface if you have the temperature set particularly high, although it does have a child-lock setting.

This Dunelm 2000W Contemporary Round 9 Fin Oil Filled Radiator review puts this oil-filled radiator to the test to see if it has the power to heat a home in the middle of winter without driving up energy bills.

After testing, I think it's one of the best oil-filled radiators you can buy today. Especially if you’re on a budget.

In a nutshell

The 2000W Contemporary Round 9 Fin Oil Filled Radiator may not have come from a big-name oil-filled radiator brand, but it can certainly compete with the big dogs. Offering a stylish and compact design, three heat settings, a thermostat and castor wheels for everyday portability, it can successfully act as an additional heater or replace your radiators when you want to save energy and keep your heating off.

As I unboxed the product, it was clear to see that it’s not the prettiest type of heater you can buy - especially compared to some of the best electric heaters - but in terms of oil-filled heaters (which are generally quite unattractive), it’s certainly not the ugliest.

Plus, the heat output was impressive no matter which room I tested it in, successfully heating up a space that had had the radiators turned off the night before (in the middle of winter) and keeping a larger living space at a constant temperature throughout the day.

And while the controls do take a little bit of getting used to, by the second or third use it had just become part of my everyday appliance routine.

Unboxing, setting up and first impressions

The Dunelm 2000W Contemporary Round 9 Fin Oil Filled Radiator was delivered extremely quickly, and as someone who receives a lot of parcels every week, I didn’t have to do any guesswork as to what this particular parcel was. The branding and the product name were clear as day on the packaging - which was, unfortunately, slightly damaged (but not so much that it damaged the product inside).

From the box alone, I was impressed. It was incredibly light and extremely slim - something I was eager to see after recently testing the very slim AENO Premium Eco Smart Panel Heater just a few weeks earlier. Not only that, but it was also encased in minimal packaging. In fact, aside from the main delivery box and a smaller box for the castor feet and the wheel plates, there was no other packaging present. So, it scored major eco points from me.

The only thing I will say is that the oil-filled radiator comes without the feet on it, which means it’s impossible to stand it upright while you’re getting the smaller box of components out of the main box. This is something I learned the hard way when the whole thing fell on my foot and left a very nasty bruise on my foot (and my ego). However, it didn’t take me long to pop the feet - albeit with the help of my husband.

To do this, all we had to do was turn the oil-filled radiator upside down and attach the castors to the wheel plates using the domed nuts which are supplied. You then have to tighten them with a spanner, which, annoyingly, isn’t supplied.

While it wasn’t difficult, I will say that it’s perhaps a two-person job if you want to get the assembly done and dusted quickly and efficiently. So, this is something to consider if you’re buying it solo or are buying it for elderly relatives.

Design

By all intents and purposes, oil-filled radiators aren’t pretty. They’re often very big and clunky, and the obvious fins make them impossible to hide. In fact, I typically tend to lean more towards the modern, digital oil-filled radiators like the Pro Breeze 2000W Digital Oil-Free Radiator with Eco Mode as the fins aren’t as prominent, and it looks a bit more like one of the best electric heaters instead.

However, I do have to say that this Dunelm oil-filled radiator is more stylish than most. The contemporary look adds some curves to what are often very harsh and brutal appliances, and the black colourway I tested adds a sense of sophistication to the overall look. It’s also available in grey and cream - but I do think that Dunelm would benefit from having a white colourway as well.

I also LOVED the fact that this Dunelm oil-filled radiator comes with cord storage on the side. This makes it so easy to store and move around the home, and means you can tuck it away without tripping on the cord or stepping on the plug when it’s not in use.

Ease of use

The controls of oil-filled radiators tend to fall into one of two categories; digital and manual. And while you’d assume that digital controls are easier, almost every oil-filled radiator on the market is confusing when it comes to the controls - and the Dunelm 2000W Contemporary Round 9 Fin Oil Filled Radiator is no different.

In total, there are two dials on this model - the main heat setting switch (with 0 indicating that it’s turned off, Ⅰ indicating low heat, Ⅱ indicating medium heat, and Ⅲ indicating high heat), and the temperature thermostat - and both require a simple turn clockwise to turn the oil-filled radiator on and to crank up the thermostat. A red light will then turn on.

However, there are no numbers on the thermostat or any indication of what temperature you want to turn it to. Instead, the only way to control the temperature of this particular model is to turn the thermostat anti-clockwise until the red light extinguishes. It will then maintain that temperature until you want to turn it off completely.

But without any numbers on the dial, I had no indicator of what temperature the thermostat was at during testing - and as someone who always runs cold, I felt as though I probably kept it up higher than it needed to. In fact, one day my husband came home and complained that it was sweltering hot in the living room.

So, I would appreciate a little indicator of temperature. And while it wasn’t rocket science to work out how to use it, I do wish oil-filled radiators (as a whole) would make the user experience a little easier.

Performance

To measure the performance of the Dunelm oil-filled radiator, I wanted to see how well it would fare in a very cold room. So, the night before I planned to use it for the first time I turned the radiators off in my home office and shut the door so the heat from other rooms wouldn’t waft over.

By morning, my office was freezing cold (for my liking, anyway) and had dropped to around 14℃, so I turned the oil-filled radiator on and waited for the magic to happen.

I know some oil-filled radiators can be noisy, so I was pleasantly surprised to see/hear that this one was relatively quiet. It was also extremely quick to heat up. And just ten minutes after I’d turned it on, it was already too hot to touch.

Because of this, it wasn’t too long before it had greeted the whole room, and it was about 45 minutes before I felt comfortable enough to turn the thermostat down to where it would maintain this temperature. During this time, I didn’t ever feel the need to turn my radiators back on.

However, I like to test products on multiple occasions and in multiple rooms to get a better judgment on them, so I continued to use it over the next two weeks in my living room and even in the bedroom. For my small home - where no room is bigger than 3.5mx3.5m, it was more than enough to take the chill off the space when the central heating was on. Especially as you can increase and decrease the heat output to suit you throughout the day.

The only thing I will say is that the electrical cord is quite short, and although the instruction manual told me to keep it as far away from furniture and soft furnishings as possible, the short lead proved to be a little too short - even in my small home. So, I do feel as though those with larger homes may struggle with the positioning, which may ultimately affect the heat output. After all, the closer you are to it, the more you get to make the most of it.

However, the cord storage on the side of the oil-filled radiator was a nice touch, and allowed me to tuck the whole thing away when I was finished and wanted to roll it out of sight on the castor wheels.

Energy use

Ultimately, the cost to run an oil-filled radiator depends on the wattage of the model you have and the current price of electricity. At the time of writing and according to the current energy price cap, the Dunelm 2000W Contemporary Round 9 Fin Oil Filled Radiator cost me 50p per hour to run.

This is similar to the claims made by Dunelm that this particular model should cost around 45p per hour. And while it’s not the cheapest electric heater to run, it’s certainly not the most expensive, either.

Plus, a major perk of the oil-filled radiator vs ceramic heater debate is that oil-filled radiators will turn themselves off when the desired temperature has been reached - or at least maintain a constant temperature. This means that it doesn’t waste energy when you don’t need it, which can save you some pennies in the long run.

How does it rate online?

The Dunelm 2000W Contemporary Round 9 Fin Oil Filled Radiator rates extremely highly online, and at the time of writing, it has over 150 reviews with an average score of 4.4 stars out of 5. Customers praise how quickly the oil-filled radiator heats up, how quickly it can heat smaller areas of the home, how cheap it is to run, and the fact that it’s easily transportable.

However, some have criticised the overall size of the Dunelm oil-filled radiator and stated that it’s not as suitable for larger spaces as it is for smaller ones.

How does it compare to similar models?

In terms of appearance, the Dunelm Contemporary Round 9 Fin Oil Filled Radiator is most similar to the VonHaus 6 Fin 800W Oil Filled Radiator, which offers the similar black colourway and the very obvious fins. However, that’s where the similarities end. For starters, the Dunelm oil-filled radiator offers more power (with a max power of 2000W instead of the VonHaus’s 800W), more temperature settings (three instead of the VonHaus’s one), and fins (nine fins instead of the VonHaus’s six).

However, the VonHaus offering does trump the Dunelm oil-filled radiator in terms of price. Although the Dunelm model is still relatively affordable at just £59, that’s fairly expensive compared to the VonHaus’s £29.99.

In terms of performance, the Dunelm oil-filled radiator is very similar to the Pro Breeze 2500W Oil Filled Radiator with 11 Fins - but there’s no doubt that the Pro Breeze does offer more in terms of power and performance. The Pro Breeze features 11 fins, 2500W of power, three temperature settings, and a timer (which the Dunelm oil-filled radiator doesn’t have).

The Pro Breeze is bigger and chunkier than the Dunelm oil-filled radiator, but the Dunelm oil-filled radiator is cheaper than the Pro Breeze model - so if you’re happy to sacrifice a little bit of power for a cheaper price and a smaller size that can easily be tucked away when you’re done, then the Dunelm model could be a better option for you.

Should you buy the Dunelm 2000W Contemporary Round 9 Fin Oil Filled Radiator?

If you’re looking for an affordable oil-filled radiator that won’t break the bank but will help you to beat the chill, then I do recommend the Dunelm oil-filled radiator. The range of colourways means you can tie it into your home decor and the castor wheels allow you to move it out of the way when you’re not in use, and the overall heating power was impressive.

If you’re looking for something with more advanced technology and features, however, this model might not be for you. It’s very basic and uncomplicated when you get used to it, but those who want a timer or more detailed temperature control won’t get what they want.

So, it’s best to weigh up what exactly you want from an oil-filled radiator before you part with your cash.

With the coldest months of the year right around the corner, you might be thinking about investing in a portable electric heater to warm up your home. To help you out, we’ve put two of the most popular options up against each other, comparing ceramic heaters vs oil heaters, also known as oil-filled radiators, to determine which is the best electric heater.

When choosing an electric heater, you want to know that you’re getting the very best for your budget, so which option is right for your needs? Making these sorts of purchases can often be a bit of a minefield, but you want to be confident that the heater you choose will heat your home efficiently while being affordable too.

Both ceramic heaters and oil heaters are great choices, but does one stack up above the other? To help you decide which portable heater to invest in, a variety of industry experts walk us through the pros and cons of both so that you can make a fully informed decision and keep your home warm this winter.

Ceramic heater vs oil heater: What is the difference?

When it comes to choosing a portable heater, ceramic heaters and oil heaters are both good options, but what’s the difference between them? While they are pretty similar in the way that they work, they do have their advantages and disadvantages.

Oil heaters are, as you may have guessed, filled with oil inside the radiator. The oil is heated up using an electrical element. It’s essentially a convection heater that emits heat through its columns, also known as ‘fins’.

On the flip side, ceramic radiators use electricity to heat up using resistive heating. This involves passing an electric current through a conductive ceramic plate, creating resistance and in turn creating heat. The different ways that oil heaters and ceramic heaters warm up create a difference in heating time, as Lee Devin from Homecure Plumbers explains.

‘Ceramic heaters heat up faster than oil heaters and offer efficient on-demand heating for small or medium-sized rooms. On the other hand, oil heaters take a little longer to heat up (around 20-30 minutes), but are better for maintaining steady temperatures in larger spaces.’

A great example of a ceramic heater would be the Small Olive Square Heater from Dunelm. At just £30, this stylish ceramic heater offers a great heat source without taking up much space. In comparison, the VonHaus 11 Fin 2500W Oil Filled Radiator might be bigger, but it provides long-lasting heat and has a 24 hour timer.

Ceramic heater vs oil heater: Which produces the most heat?

Both ceramic and oil heaters provide a good source of heat, but is one better than the other? Put simply, ceramic heaters will heat up faster, whereas oil heaters will retain heat for longer.

‘Ceramic heaters, like the DREO Space Heater Solaris 718, are designed for fast, efficient heating, making them ideal for quickly warming up medium to large-sized rooms,’ explains Joshua Gun, VP of DREO. ‘They deliver concentrated warmth where it’s needed, allowing for rapid comfort. In contrast, oil heaters such as the DREO Radiator Heater OH712 offer steady, long-lasting heat, perfect for larger spaces that require consistent warmth.’

Nicolas Aukland, heating and energy expert at Trade Radiators also added, ‘Which radiator produces the most heat depends on what you're using them for. For example, ceramic heaters are designed to provide instant heat, which means they're good at quickly warming up smaller areas, ideal for spot heating. However, they do tend to lose heat quickly as soon as they're turned off, so they need to be on constantly to provide heat.’

‘Oil heaters however will take longer to warm up, but will radiate heat better,’ Nick continues. ‘This means that they keep spaces warm for longer in general. All in all, if you’re looking for rapid heat in a specific, smaller spot, then a ceramic heater is likely the better option, but for consistent warmth over time, an oil heater is more efficient. So it all depends on the location and your heating needs.’

Ceramic heater vs oil heater: Which is bigger?

If size comes into play, oil heaters are usually the bigger of the two options. Ceramic heaters tend to be more compact and lighter too, so if you’re limited on space or you want a heater that’s easy to move around, a ceramic heater might be the better option.

‘Oil heaters are typically larger and bulkier due to their radiator-style design, while ceramic heaters like the DREO 2-in-1 Tower Fan & Heater MC706 are more compact and portable, ideal for tighter spaces,’ says Joshua Gun.

‘The MC706 is sleek and space-efficient, offering both heating and cooling in one unit without sacrificing performance,’ he continues. ‘Despite its compact size, it delivers high-power output. On the other hand, the DREO Radiator Heater OH712 is larger but designed with 8 efficient fins, offering superior heat distribution. Its relocate cord to the back design ensures better control and ease of use, maximizing space while providing effective heating.’

Ceramic heater vs oil heater: Which is more affordable?

When considering which is the cheapest electric heater to run, it’s important to look at both initial costs and long-term costs, as Lee Devlin explains.

‘Ceramic heaters are typically more affordable to buy and run than oil heaters. They generate more heat per watt, and the long-term cost of gas or electricity is cheaper than oil. However, oil heaters retain heat for longer and need less power to keep warm, making them more efficient in terms of long-term energy consumption.’

It’s also worth noting that oil heaters will switch off once the desired heat has been reached, which can help keep costs down, whereas ceramic heaters will continue to use electricity to keep them hot until you turn them off.

While ceramic heaters do tend to be cheaper to run, when our expert tester Rachel Tompkins tested 6 oil filled radiators, she found a good low cost alternative in the 500W De'Longhi TRNS0505M, if you’re set on getting an oil heater.

‘If you only have a small space to heat then the 500W De'Longhi TRNS0505M offers the lowest running costs of all the oil-filled radiators in our round-up,’ recommends Rachel. ‘It can't dish out as much heat as its 2500W competition, but it's small, compact, lightweight, and very easy to use. Plus, there's zero self-assembly required making this heater ready to use straight out of the box.’

Ceramic heater vs oil heater: Final Verdict

Which option you go for really depends on your own unique needs. Ceramic heaters tend to have a lower upfront cost and provide almost instant heat, whereas oil heaters provide a steadier heat source and will shut off when the desired heat is achieved, which can save you money.

‘Oil radiators can be a good addition, as they help bring steady and consistent heat to any home,’ adds Isabella Forgione, small appliance expert at AO.com. ‘Using internal oil to retain warmth for a long time, they may take a longer time to heat than a ceramic heater – but do so at a much more efficient rate, retaining sustained heat for a far longer time. Overall, an oil radiator is also a good choice if you’re looking for a bulkier heater to warm a much larger area.’

Maintenance of your electric heater is worth considering too. Ceramic heaters can gather dust inside their internal fan. This can decrease the efficiency, so it’s important to clean the fan around once a month. The fans in ceramic heaters may also need replacing annually, whereas oil heaters require little maintenance.

If your budget is tight and you want something that’s going to provide heat quickly for a small space, a ceramic heater is the right choice. Whereas if you’re looking for something to use on a regular basis that will provide ongoing heat to larger spaces, go with an oil-filled heater.

If you get chilly overnight during the colder months, an oil-filled radiator can be a great idea to efficiently warm up just one room in the house without turning the heating on. But if you know you're liable to drift off before hitting the off switch on your little rad it's important to know if you can leave an oil-filled radiator on overnight.

The best oil-filled radiators can keep you and smaller rooms and spaces much warmer, and the best part is that generally, the experts all agree that an oil-filled radiator can be left on overnight.

But whether or not this makes the most financial sense, is another thing.

‘Modern models have safety features like built-in timers, tip-over protection, and thermostats, making them highly reliable,’ says NationalInsulationSupplies.co.uk’s Heating and Insulation Expert, Michael Wray.

‘These heaters are designed with a high boiling point, ensuring the oil inside maintains a stable pressure. Additionally, with no moving parts, they operate silently, eliminating any noise that might disrupt your sleep. So, these features make your oil-filled radiator safe and convenient to use throughout the night.’

Are oil radiators safe to run overnight?

If you’ve ever asked yourself, ‘are oil-filled radiators dangerous?,’ the simple answer is no, not if they are used correctly. As long as you follow the safety measures above, you should be completely fine.

In fact, ‘out of all types of electric heaters, oil heaters are generally the safest to leave on overnight,’ Nicholas proposes. ‘However, they still are an electrical appliance which comes with its own risks when being left on overnight. I would always recommend turning it off overnight, or at least setting a timer which would mean that it turns off automatically.’

And, of course, using modern models with advanced safety features is always recommended for extra peace of mind.

What to consider when running an oil filled radiator overnight

If you do choose to leave an oil filled radiator on overnight, there are a few things to remember. Firstly, if you have an oil filled radiator that is a few decades old, while it might work perfectly fine if you’re able to keep an eye on it, leaving it unattended – especially while you sleep – could be potentially riskier than using a new or more modern model.

‘It is important to purchase newer models as they are designed with modern safety functions like automatic shut-off, thermal cut-off, and child locks for extra protection. Older models may have electrical issues due to past use, which can be a safety hazard,’ Michael warns.

You’ll also want to ensure that you keep it away from any flammable items, like curtains, furniture or bedding. The same can be said for placing the radiator behind upholstered furniture, as the fabric can be damaged by the heat from the radiator. And never drape clothes or blankets over the radiator – like you might with your central heating – as this can block the unit from effectively distributing heat and increase the risk of fire.

In addition to this, ‘use a wall socket directly, rather than an extension cord to reduce fire risk, and choose a radiator appropriate for the room size to avoid overheating,’ says David Miloshev, Electrician and HVAC/Heating Expert at Fantastic Services. And ‘make sure the radiator is on a flat, stable surface to prevent tipping,’ advises Nicholas Auckland, Heating and Energy Expert at Trade Radiators.

Finally, ‘you can never be too safe when it comes to heating units, so before going to bed, check that the radiator is operating correctly, and set the thermostat to a safe and energy-efficient temperature,’ Michael suggests. “Regularly check for signs of wear, damage, or leaks in the radiator or its cord,” too, David adds.

FAQs

Is it cheaper to leave an oil-filled radiator on all the time?

While you might be tempted to leave an oil-filled radiator on all day long during particularly chilly weather, the experts would recommend that you don’t, both in terms of the additional expense and not truly feeling the benefit of the added heat as and when you need it.

‘Oil-filled radiators are still electrical appliances, so I wouldn't say it's cheaper to leave an oil-filled radiator on all the time, especially in comparison to having a traditional central heating gas radiator on,’ Nicholas affirms. ‘Instead, I recommend using the radiator only when needed and leveraging a thermostat or timer to regulate usage will save money on energy bills.’

‘Technically, you can leave an oil-filled radiator on 24/7, but it’s not recommended, as prolonged use without breaks can strain the radiator, potentially shortening its lifespan,’ David warns.

And Stephen Hankinson, Radiator Expert from Electric Radiators Direct, agrees. ‘While oil filled radiators are extremely energy-efficient and can maintain warmth for extended periods, leaving one on continuously is generally not the most cost-effective approach.’

Essentially, it’s best to have a heater and ‘heating schedule that matches your lifestyle and individual routine, so your heating only ever comes on when you need it. This is perfect if you want your heating to switch on or off at certain times throughout the night,’ Stephen concludes.

Over winter portable heaters are a great way to keep warm without facing a hefty heating bill from rising energy bills. Oil-filled radiators are one of the most portable heaters on the market, but are oil-filled radiators any good?

The best oil-filled radiators provide a quick and easy way to add extra warmth to smaller spaces, helping you to feel warm and cosy over the colder months. But are they as good as central heating or the best electric heaters?

Well, we put this to the experts and overall the consensus is that yes, oil-filled radiators are good. However, there is a little more to it than that. This is why we've broken it down into the pros and cons of using an oil-filled radiator to help you decide if it's the right choice for your home.

What are the pros of an oil filled radiator?

1. Even and long lasting warmth

Oil-filled radiators work in a similar manner to central heating explains Nicholas Auckland, Heating and Energy Expert at Trade Radiators. They work to warm the room ‘without creating 'hot spots' or blowing out any air, which can be uncomfortable, can trigger allergies and can, of course, mean that the room is heated unevenly.’ So, this can make them a great option for providing even warmth to smaller spaces and rooms.

In addition to this, ‘the oil inside stays hot long after being switched off, which helps to keep rooms warmer for longer – a huge bonus in colder temperatures. The oil also heats evenly throughout the radiator, meaning you’re getting the most from the radiator,’ adds Aneesa Khan, Assistant Home Electricals Buyer at VonHaus.

2. Portability

One of the biggest pluses of owning an oil-filled radiator is the fact that most are relatively compact and come with wheels, making them easy to move around the house. So, if someone is feeling particularly chilly or you want to heat a specific space in your home like a small office or reading nook you can pull the oil-filled radiator so that it's placed wherever you need it.

3. Built-in safety features

Most oil-filled radiator models come equipped with a number of handy safety features. So, if you’ve ever asked yourself ‘are oil-filled radiators dangerous?’, we can confirm that as long as they are used correctly, you have nothing to worry about.

From overheat protection to built-in timers and thermostats, many even come with a tip-over switch, meaning if the device is accidentally tipped over it will switch off automatically. All of these certainly give you some peace of mind as you use your oil-filled radiator.

4. Low maintenance

‘Despite being called 'oil-filled', the oil isn’t consumed as such but instead it acts as a heat reservoir to hold the heat,’ Nicholas explains. ‘This means that no refuelling is required, which reduces maintenance pressures and eliminates ongoing costs. All you'll have to do is keep an eye on the cleanliness of the radiator, and the wires to ensure they're in good condition.’

5. Quietness

Oil-filled radiators work almost silently, apart from the occasional glug as they heat up.

‘Unlike fan heaters, which can be quite noisy, oil-filled radiators tend to operate much more silently. This makes them ideal for the likes of bedrooms, offices, or any other space where peace and quiet is important,’ Nicholas explains.

‘Because they heat the oil internally, you’ll only hear the occasional gurgle of oil,’ Aneesa from Vonhaus adds.

6. Aesthetics and choice

Certain fan heaters aren’t exactly the most aesthetically pleasing, while oil-filled radiators come in a wide selection of colours and sizes, allowing you to choose something that fits in with your existing interiors.

‘One of the main benefits of oil-filled radiators lies in their impressive variety. From classic column builds to sleek flat panels and elegantly curved bars, you’re guaranteed to find the perfect accompaniment to your home’s aesthetic,’ Stephen Hankinson, Radiator Expert at Electric Radiators Direct, says.

‘Sizes can range from five fins right up to 17 fins, and there are even some closed fin models available too,’ Aneesa adds.

What are the cons of an oil filled radiator?

1. Slower to heat up

One of the biggest disadvantages of an oil-filled radiator is that it takes longer to heat up compared to other types of heaters, as the oil needs time to reach the desired temperature before it can start radiating warmth. This might not necessarily be a deal breaker for many, but it is worth bearing in mind if you’re looking for more of an immediate heat.

2. Not suitable for larger spaces/rooms

While they can work really well in smaller spaces and rooms, they won’t make much of a difference in a particularly large or open-plan room. ‘They also provide radiant heat to the surrounding area but lack the ability to focus heat in a specific direction, which may not suit all heating needs,’ says Nick Duggan, Managing Director of The Radiator Centre.

3. They can be heavy

Even though they are portable and can be moved from room to room, as you go to take it out of the box or bring it home from the shops, you will notice just how heavy an oil filled radiator can be.

‘This is due to their oil content inside, as well as their heavy metal casing,’ Nick justifies. ‘This is also why they're usually on wheels, so you don't need to pick them up for extended periods of time.’

4. Higher up-front cost

You may find that an oil filled radiator is more expensive than other heaters and radiators, however, the experts would argue that ultimately you get what you pay for, as they are more durable and heat more effectively than some of the alternatives.

5. High surface temperatures

Like you might expect from most radiators or heating devices, an oil filled radiator can get particularly hot, which is beneficial at keeping you warm but can be a bit of a hazard for small children and pets, who might reach out to touch it. So, it’s important that you don’t leave them unattended when it is on or even when it’s cooling down.

Verdict

Taking all of that into consideration in short yes oil-filled radiators are good. ‘Oil-filled radiators offer the perfect balance of efficiency and comfort – delivering steady, silent warmth that lasts long after you turn them off. With no noise, no fuss, and low maintenance, they’re a smart, reliable choice for keeping your home warm without running up your energy bill,’ Stephen says.

However, whether an oil-filled radiator is worth getting depends on your heating needs and overall preferences. For example, ‘they are an excellent choice if you’re looking for a quiet, energy-efficient, and reliable heater that provides consistent warmth without drying out the air. They’re especially suitable for small to medium-sized rooms and spaces where steady, long-lasting heat is desired,’ Nick concludes.

While the initial cost might be higher and they do take a bit longer to warm up, their efficiency and low maintenance often make up for these drawbacks over time. However, for larger spaces or immediate heat, other options like electric fan heaters or central heating may be more suitable and affordable in the long-run.

Our favourite oil-filled radiators

Now that the temperatures have started to dip, with many parts of the UK experiencing freezing conditions, you will probably have been considering alternative heating methods like oil-filled radiators. However, before you invest you might have asked are oil-filled radiators dangerous

The best oil filled radiators will keep you and your home warm over the colder months and are especially handy in smaller rooms or if you don’t necessarily want or need to heat your whole home. The good news is that these relatively inexpensive heaters are not dangerous, as long as they are used correctly.

'They are relatively low risk and are unlikely to ignite any items nearby as they don’t have exposed heating elements. Plus, they have a less intense heat compared to a fan or halogen heater,’ explains Electric Radiators Direct's Radiator Expert, Stephen Hankinson.

When it comes to using them correctly, there are a few rules that you’ll want to follow to stay safe and ensure that you’re getting the most out of the heating device.

Is it safe to leave an oil filled radiator on?

Depending on the room or area of your home that you’re looking to heat, you might want to leave your oil-filled radiator on for most of the day or even overnight. Thankfully, ‘most oil-filled radiators now have overheat protection, which means they will switch off when they get too hot,’ says Aneesa Khan, Assistant Home Electricals Buyer at VonHaus. If you’re shopping for a new oil-filled heater, this is certainly something to bear in mind.

It should also have ‘safety features such as a thermostat and a timer,’ according to Trade Radiators’ Heating and Energy Expert, Nicholas Auckland. ‘If it doesn't have any of these features, it may be a bit more dangerous.’ So, if you’re using an oil-filled radiator that has been in the family for decades, it might be worth upgrading to a newer model to ensure that it has all the relevant safety features.

‘While oil-filled radiators are built for extended use, leaving them on continuously is not advisable,’ Rob Nezard, Heating Expert and Founder of UKRadiators.com, proposes. ‘Over time, constant operation may reduce efficiency and wear out components. It’s better to use a timer or thermostat to regulate usage.’

And even though the idea of coming home to a warm and toasty room might sound particularly appealing, ‘as with any other electrical appliance, you should always avoid leaving it turned on while you're away from the home,’ Nicholas advises. He also recommends not leaving it turned on overnight ‘without setting a timer.’

Not only will this save you some money on your bills, as you won’t necessarily feel the benefit of the radiator while you are sleeping, but it also saves you from essentially leaving it completely unattended as you sleep.

Are oil-filled radiators safe to leave unattended?

Speaking of leaving it unattended, ‘oil-filled radiators are generally seen as the safest electrical radiators to leave unattended,’ according to Nicholas. But caution is still advised, as with any electric appliance. For example, if you have small children or pets, you won’t want to leave them unattended in the same room as an oil filled radiator, as they can be easily knocked over.

As you might expect, ‘the high surface temperatures could burn them,’ too, Aneesa affirms. So, it’s more of a case of ensuring that the device is used safely than worrying about the radiator being left unattended.

Tips for safely using an oil filled radiator

As we say, oil-filled radiators are safe to use, as long as they are used correctly. But the experts also have a number of top tips to use them safely.

It’s important to ensure that the radiator is on a flat, stable surface to prevent tipping. Check that the power wire is in good condition (not frayed or damaged) before you plug it in.

Aneesa also warns that you ‘do not use this type of heater in the immediate surroundings of a bath, a shower,’ or something like a swimming pool either.

FAQs

Are oil filled radiators a fire risk?

‘In comparison to other types of electric heaters, oil-filled radiators don't really pose a major fire risk. This is because oil-filled radiators don’t have any exposed heating elements, or fans that could spark or ignite dust,’ Nicholas reveals.

In contrast, ‘if an electric fan heater had blocked ventilation, then it becomes a fire risk, whereas oil-filled radiators don't have this danger as the oil heats up in a similar way as the water heats up in a gas/central heating radiator.

However, the experts recommend that you avoid placing an oil-filled radiator – or any heating device – too close to flammable objects like curtains, furniture or clothing. This could potentially become a fire risk depending on the material that they’re made of. You should also ‘never cover them with clothes,’ Stephen warns.

And finally, like most appliances that are plugged into the mains, ‘you should keep an eye on the wire and make sure that it doesn't become damaged at any point,’ Aneesa admits. ‘You should also avoid using the radiator if there are any other visible signs of damage.’

One thing that could cause a fire hazard, though, is using extension cords, which could cause the power source to overheat, warns Jack Coles, Heating Expert at MyBuilder.com. Instead, ‘experts advise that you plug them directly into a wall socket,’ he continues.

Are oil filled radiators safe for health?

Most modern oil-filled radiators should come with a few safety features, like built-in timers and overheat protection. ‘They also do not release fumes or carbon monoxide, making them ideal for indoor use. Additionally, they provide gentle, radiant heat that doesn’t dry out the air, making them suitable for people with respiratory concerns,’ Rob affirms.

Plus, ‘they operate rather quietly, which promotes better sleep and reduces stress,’ Nicholas adds, which could be particularly handy if you plan on using one in your bedroom.

Obviously, you’ll want to be careful not to touch the heater when it is switched on to avoid burns. But other than that, you should be completely safe to use an oil-filled radiator in your home, whether that’s to provide some warmth as you work from home or as you gather around the sofa at the end of a long day.

And finally, you should always make sure that they're placed sensibly. If you were to set one up in the middle of a room or in a hallway, this could cause a trip hazard which could be rather dangerous.

Aldi is selling two new electric heaters to help curb the cold weather – an oil-filled radiator and an electric fan heater – both priced at under £30 each and landing in stores tomorrow, the 16th of January.

The best electric heaters are a no-brainer buy for the winter season if keeping warm without breaking the bank is your top concern. Not only will the cost of running an electric heater set you back just mere pennies, but their compact size is also ideal for those in need of a discrete and non-disruptive way to keep a house warm in winter.

Aldi's new oil-filled radiator and electric fan heater will be available to shop in Aldi stores nationwide, and given their super affordable price point, we suspect stock won't last for long.

Aldi oil-filled radiator and electric fan heater

The Oil Filled Radiator (£29.99) and Electric Fan Heater (£24.99) are the hottest heating buys to keep a watchful eye on this winter season, especially as the oil-filled radiator vs fan heater debate continues to be a hot topic.

Oil-filled radiators and fan heaters are some of the cheapest electric heaters to run, allowing shoppers to save energy at home compared to relying on traditional gas heating. A lot of the difference will just rely on aesthetics and heat distribution.

Although they're both formidable choices for electric heaters, generally speaking, fan heaters tend to heat a room quicker, but can sometimes struggle with even heat distribution compared to oil-filled options. However, as a result of this, fan heaters tend to work great in smaller spaces – which is something to keep in mind.

The Oil Filled Radiator option is also more affordable to run. It will cost households just 23p per hour to run, while the Electric Fan Heater will cost a slightly higher 29p per hour to run. However, this is still more affordable than the general cost to run of central heating.

Compared to the previous Aldi stove-effect electric heater, these new electric heaters are more than half the price of last year's release, with two different models to choose from depending on personal preference and requirements.

If you're on the hunt for one of the best oil-filled radiators, Aldi's oil-filled radiator is compact and easy to store, featuring an adjustable thermostat and overheat protection, making it a cost-cutting must-have for the winter. The power cord storage allows for easy storage in even the smallest of rooms.

If we had to compare, we'd say that Aldi's oil-filled radiator is most similar to the VonHaus 6 Fin 800W Oil Filled Radiator, which currently retails for £39.99. Therefore, Aldi's £29.99 offer is much more competitive.

On the other hand, the electric fan heater boasts four power settings, adjustable heating angles and tip-over protection, featuring a built-in handle for easy portability from room to room in your home.

However, in the off-chance that you're not looking to buy a new electric heater but want to hone in on improving heat efficiency in your home, Aldi is also selling a Radiator Reflector for £12.99. Easy to install, it can be easily cut to fit your radiator, the reflector features an internal bubble structure to better cut home heat loss.

This will also be available to buy in stores alongside the new oil-filled radiator and fan heater on the 16th of January.

Best oil filled radiators

Best oil filled radiator overall

Design: As portable heaters go, the Pro Breeze 2500W is probably tied with the Pro Breeze 2000W Digital Oil-Free Radiator and De’Longhi 2500W for most stylish design. Unlike the VonHaus 2500W, which is a rather dated-looking cream colour, the body of the Pro Breeze 2500W is white, which feels more modern. The black and silver control panel is also smart and looks much more contemporary than most.

Assembly: There is some assembly to do with this radiator, but it's minimal. You just need to turn it upside down to attach the caster wheels using metal arc-shaped brackets and four wing nuts, which need to be screwed into place. It took our tester, Rachel, under five minutes, although at 8.3kg in weight, you do need a little strength and dexterity.

Ease of use: The large stainless steel-effect control knobs, which operate the temperature and thermostat, are straightforward and very easy to use. However, programming the timer function is considerably more complicated. The timer dial has 96 segments, each representing a 15-minute period. You have to push the segments in for the time period you want the heater turned on, which requires good eyesight and decent finger dexterity.

Performance: During testing, Rachel found the Pro Breeze 2500W 11 Fins Oil Filled Radiator with Thermostat Control heated up very quickly. Sitting next to it in her office, she could feel the heat radiating onto her legs within minutes, and in less than ten minutes, her office (which measures approximately 2m x 3m) felt warm and cosy. It had a real warmth impact on larger rooms too, such as her bedroom measuring 4.5 x 3.5 metres.

Energy use: That powerful performance is perhaps unsurprising given that this is one of the highest wattage radiators in our round-up, using 2500W of power on its highest of three temperature settings. This certainly affects how much it costs to run an oil-filled radiator. However, you can switch down to the 1500W or 1000W settings to save on energy if you need less heat. As the current average electricity costs (as of the October 2025 price cap) of 27p per unit, that means on its highest temperature setting, this model costs roughly 68p per hour to run.

Overall: An attractive design, generally easy-to-use controls, minimal assembly, and powerful performance combined with a relatively affordable price point mean we rate the Pro Breeze 2500W with 11 Fins the best oil-filled radiator you can buy for heating a large space. The De’Longhi 2500W might just pip it to the post on performance, but it's nearly twice the investment of the Pro Breeze. That said, if you only have a small area to heat, you could save even more cash by opting for the lower-powered VonHaus 6 Fin 800W Oil Filled Radiator or De'Longhi TRNS0505M 500W Oil Filled Radiator further down in this round-up.

Best budget oil-filled radiator

Design: The 6 Fin VonHaus Oil Filled Radiator is one of the smallest in our round-up, meaning it's compact, lightweight, and easily portable. That does mean you sacrifice some power, with this radiator offering just one 800W heat setting, but it makes the mini heater perfect for smaller spaces. Like most of VonHaus' oil-filled radiators, it comes in two colour options: a smart black build and a classic off-white.

Assembly: Assembly of this small radiator took less than a minute and simply involved sliding the two feet into place, one at each end of the radiator. This was considerably easier than some of the other radiators tested, which require dexterity of fingers and a good eye in order to screw wing nuts and bolts into place.

Ease of use: There is no timer with this radiator, and only one temperature setting, but that does make it incredibly easy to use. The red on/off button is easy to see and operate, and the thermostat dial is large and straightforward, with ‘min’ and ‘max’ clearly indicated – perfect for anyone with less than 20/20 vision or who doesn't want to be overwhelmed by multiple controls.

Performance: This is a small oil-filled radiator with a maximum 800W power output, so it can't compete with the 2500W models in terms of the heat it can dish out. However, if you only have a small room to heat, then it does the job.

Energy use: Of course, the plus side of that lower 800W power usage is lower running costs of around 22p per hour. If you don't have a large space to heat, that makes the VonHaus 800W one of the most economical heaters to operate in our round-up.

Overall: The VonHaus 800W Oil Filled Radiator lacks power and functionality compared to the larger heaters in this round-up, but it is one of the easiest to assemble, and definitely the easiest to use of all the oil-filled radiators we've tested, making it great for less dexterous users. It's also the cheapest oil-filled radiator in our round-up, making it a great budget buy, and if you don't need to heat a large space, then its 800W power usage means it's more energy efficient than larger models too.

Most powerful oil-filled radiator

Design: This radiator is large and heavy, weighing in at a whopping 17.52kg, although it immediately felt extremely solid and durable on unboxing. Unlike most of the oil-filled radiators on the market, the De’Longhi Dragon 4 has an encased body rather than open fins, which gives it a much more contemporary appearance. And apparently, there’s science behind that design. The manufacturers refer to it as a ‘chimney design’, stating the special coil fins provide rapid hot air flow that quickly warms up a room for even and consistent heat distribution.

Assembly: This was by far the easiest large oil-filled radiator of the bunch to assemble because it only needed to be turned upside down so the wheels could be pulled out. No screwing required. However, at 17.52kg, inverting it isn't for the faint-hearted. Turning it over solo was a challenge and definitely more of a two-person job.

Ease of use: Like the Pro Breeze 2500W, the main control dials on the De’Longhi are large and easy to twist clockwise or anti-clockwise. However, again, the timer dial has toothed segments, each representing a 15-minute period, that need pushing in and require good eyesight and dexterity. However, what the De’Longhi does have is the ability to override the timer whenever you wish to, which means you don't need to reset the fiddly timer very frequently.

Performance: Similar to the Pro Breeze 2500W, the De’Longhi Dragon 4 offers three temperature settings: 1000W, 1400W, and 2500W, and on its highest setting, its powerful performance made short work of heating our tester's 2m x 3m office, and likewise her draughty bedroom, which measures 3.5m x 4.5m.

Energy use: Like the Pro Breeze 2500W at the top of our round-up, at maximum heat output, the De’Longhi Dragon 4 costs roughly 68p per hour to run at current energy prices.

Overall: Our tester couldn't fault the De’Longhi Dragon 4 on performance, its powerful 2500W heat output making short work of warming the largest and most draughty rooms in her home. However, it is large, heavy, and a significant investment, coming in at nearly twice the price of the Pro Breeze 2500W at full RRP. However, in its favour, it does feel very solidly built, and comes with a 10-year manufacturer's warranty, which could mean it represents the better long-term value if you can afford its initial investment.

Most stylish oil-filled radiator

Design: While not the heaviest oil-filled radiator we've tested (that honour goes to the De’Longhi 2500W Dragon 4 Oil Filled Radiator, this Duux model is still hefty at just over 15kg. However, what it lacks in terms of manoeuvrability, it certainly makes up for in terms of its design. This oil-filled radiator is definitely the sleekest, most stylish oil-filled radiator we've come across. This is all thanks to the convector-heater-like appearance, which hides the fins within. So, it won't look like an eyesore in your house.

Assembly: It took our tester just two minutes to assemble this oil-filled radiator, and Duux provided screws, an Allen key and a mini spanner to attach the wheels to the bottom of the appliance. And while the wheels certainly aid manoeuvrability if you plan on wheeling it from room to room, this particular model also comes with static legs, so you can choose which ones you want to use.

Ease of use: The Duux Edge 2000W Oil-Filled Radiator is the only model we've tested that can be controlled via an app, making it the perfect option for those who prefer smarter appliances. Of course, you can still control it via the onboard controls or the remote control if you'd prefer, but the wide array of special features on the app make it invaluable. You can set schedules, adjust your desired temperature, turn on the child lock setting, turn on night mode, or just monitor your energy usage.

Performance: While it offers 500W less than the Pro Breeze 2500W or the De’Longhi Dragon 4, the 2000W heat output of the Duux Edge 2000W Oil-Filled Radiator still impressed our tester. This is largely thanks to the fans within the appliance, which allow heat to be distributed quickly. The cherry on top of the cake was the heat retention, as she noted that the oil-filled radiator retained its heat for an hour after she turned it off.

Energy use: At 2000W, this Duux oil-filled radiator isn't the most expensive to run, but it's also not the cheapest. At the current price cap, it'll set you back around 54p an hour to run - but that's only if you use it on the highest setting. Its Eco mode runs at half that, meaning it'll also cut the price in half. It's also worth noting that you can buy this model in 1500W, which not only makes it cheaper to run but also cheaper to buy, as it's £199 at Amazon.

Overall: In terms of performance, heat output and general quietness, our tester really couldn't find much to criticise the Duux Edge 2000W Oil-Filled Radiator for. Its three settings allow for customisation and energy-saving options, and the stylish design is perfect for people who don't like the traditional fin design of other models. She did find the app to be a little glitchy at some points, but with onboard controls and a remote control as backup, that's certainly not a dealbreaker. It's an investment, but one that's worth it.

Best oil-filled radiator for low running costs

Design: Just like the VonHaus 6 Fin 800W radiator, the De'Longhi TRNS0505M is super compact. And like the other De'Longhi model in our round-up, it instantly feels sturdy and well-made on unboxing. It may not be the most stylish to look at, but its small build does make it unobtrusive and easy to hide, and although this is the only portable heater on our list that doesn't have wheels, its 5kg body is lightweight and easy to pick up and move around the house.

Assembly: Another plus point of the lack of castor wheels is the fact that this means there's no assembly to do on the De'Longhi TRNS0505M. You can simply get it out of the box, plug it in, and turn it on. This made it a total dream for anyone who is strapped for time or has mobility issues, which may make assembly of the other radiators difficult.

Ease of use: Operation is also super straightforward. This heater may lack functionality compared to the competition, but that does mean that it's super simple to use. Simply flick the switch to turn the radiator on and then use the thermostat control knob to scroll through the 6 heat settings. A red light clearly indicates whether the unit is on or off.

Performance: The downside of the De'Longhi TRNS0505M's compact size and simple functionality is its heat output. At 500W, this small oil-filled radiator offers the lowest heat output of all the radiators we've tested. Whilst you wouldn’t select this radiator for heating a large room, it did a good job of heating our tester's small office (which measures approximately 2m x 3m) and kept it warm whilst she was working. However, in her larger bedroom (measuring 3.5m x 4.5m), it didn’t really make enough of an impact to warm it up or keep it warm.

Energy use: The De’Longhi 500W Nano Oil-Filled Radiator has a wattage of just 500W, which means that it costs approximately 14p an hour to run, depending on the cost of your electricity supplier. That makes it by far the cheapest oil-filled radiator in our round-up to run, which is obviously a big draw. However, those low running costs obviously need to be weighed up against the lower heat output, which means it’s less powerful and not as effective in larger rooms as the other radiators.

Overall: If you only have a small room to heat, then the De’Longhi TRNS0505M could be just the ticket. It's more expensive upfront than the comparable VonHaus 6 Fin 800W radiator, but with its 500W energy usage, it offers the lowest running costs of all the oil-filled radiators in our round-up.

Bestselling alternative oil-filled radiator

Design: The gloss finish of the VonHaus 11 Fin 2500W Oil Filled Radiator, combined with the plastic-looking control panel and black plastic-looking castors, means that this product doesn’t look particularly stylish. It's by far the most dated-looking of all the heaters in this round-up, and those plasticky controls don't feel particularly nice to interact with. However, it does feature a handy cable holder to keep the cable tidy.

Assembly: Assembly took approximately ten minutes and required the most time and effort out of all of the oil-filled radiators we've tested. Unlike many models, which have the castors already attached to a metal plate and then just require four wing nuts to be screwed into place, this one required our tester to assemble the plate to attach all four of the wheels to. It was quite fiddly to do and required good pincer control and vision, and so some people may find this challenging.

Ease of use: The power button on the VonHaus 11 Fin 2500W Oil Filled Radiator consists of a circle, about the size of a ten pence piece, which is divided into two halves. Pressing in the left half of the button activates minimum heating, pressing in the right half of the circle is medium heating, and both together equal maximum heating. These buttons felt a bit flimsy, and whilst our tester had no trouble operating them, she didn't find them particularly easy to use. The heater also has a thermostatic control that you simply twist, and a timer that has rather fiddly segments that you need to push in to control when the heater turns on and off.

Performance: Like the Pro Breeze 2500W Oil Filled Radiator with 11 Fins and De’Longhi 2500W Dragon 4 Oil Filled Radiator, the VonHaus 11 Fin 2500W is powerful, delivering the maximum heat output of all the oil-filled radiators in the VonHaus range. Like the other 2500W models in our round-up, it made quick work of heating our large, high-ceilinged bedroom measuring 3.5m x 4.5m.

Energy use: The VonHaus 11 Fin 2500W Oil Filled Radiator has a wattage of 2500, which equates to approximately 68p per hour running costs, depending on the cost of your energy supplier. Whilst this radiator is considerably more expensive to run than smaller alternatives, it’s worth remembering that its ability to heat a larger room is extremely good.

Overall: The heat output on this 2500W radiator is impressive, and it certainly did the job of warming up a large and draughty bedroom quickly. However, its performance was on a par with the similarly priced Pro Breeze 2500W Oil Filled Radiator, and we found the Pro Breeze model more attractive to look at, easier to assemble, and easier to use. However, if you find this VonHaus model available at a cheaper price point (and don't mind its not-so-stylish looks or slightly more flimsy build quality), then it's a powerful heater at a reasonable RRP.

Oil-filled radiator comparison at a glance

Best of the rest

While the options above are what we consider to be the best oil-filled radiators out there, there are other models that didn't quite make it into out top six. And we think they're still worth considering.

How we tested the best oil-filled radiators

We take how we test products extremely seriously. As we only want to recommend the best products to our readers, we ensure we have as much hands-on experience with them as possible. Every Ideal Home tester also follows a strict testing protocol to make sure every review is impartial, honest, and detailed. We even have a team of Certified Experts who have become experts in their specific fields, from furniture to vacuum cleaners.

To compile this guide of the best oil-filled radiators, we assessed how each one performed in real homes - testing them in multiple rooms to see how they fared against cold temperatures and different room sizes.

We also tested them over the course of a few days (and sometimes even a few weeks), rating each one's overall performance, including design, ease of assembly, ease of use, how quickly each portable heater could warm the space and the overall heat distribution, along with any added functionality.

We also compared the cost to purchase and the cost to run each radiator to compile our recommendations for the best oil-filled radiator to buy.

With all of this information at our disposal, I’ve been able to assign each oil-filled radiator a dedicated Ideal Home star rating. They are as follows:

5 stars - an impressive oil-filled radiator that does exactly what you expect and cannot be faulted.

4.5 stars - a high-quality and hard-working oil-filled radiator that isn't quite perfect, but is still worth the investment.

4 stars - an amazing oil-filled radiator that is worth purchasing but may need some fine-tuning before it suits every customer and every home.

3 stars - a good oil-filled radiator that works well but doesn't blow us away. In some cases, it may not heat a room as effectively as competitors or may be difficult to use.

2 stars - an affordable oil-filled radiator that will suit all budgets but is under-specced and lacks key heating features.

1 star - we would not recommend this oil-filled radiator, as it is underwhelming and does not work as intended.

How to choose the best oil filled radiator

So how do you choose the right kind of electric heater?

There are so many things you should know before buying an oil-filled radiator. And when starting your research, you'll firstly want to consider the size of the room you’re looking to heat. This will help you decide if you can manage with a smaller oil-filled radiator, which costs less to purchase and is more economical to run, or if you will need to spend more on a more powerful heater to adequately warm up the room.

The lowest-powered oil filled radiator in our round-up is the De'Longhi TRNS0505M at just 500W which offers limited heat output, but can be very economical to run in a small space, whilst the most powerful models, like the Pro Breeze 2500W Oil Filled Radiator with 11 Fins, De’Longhi 2500W Dragon 4 Oil Filled Radiator and VonHaus 11 Fin 2500W Oil Filled Radiator use 2500W and can dish out far more heat to warm up a much larger space.

Generally, you should expect a 2000-2500W oil-filled radiator to easily heat rooms and spaces up to 30m², but heat output and efficiency can also vary depending on how well (or poorly) your home is insulated and where you place it.

It’s also worth considering the weight and size of the oil-filled radiator you choose. For a person living on their own or with mobility issues, this is a big consideration, especially if you'll be moving the radiator from one floor to another. In this case, you may need to be able to lift and manoeuvre the heater upstairs comfortably. After all, oil-filled radiators can be dangerous.

Another key consideration is how easy the heater is to use. If you struggle with technology, a digital control panel may not be ideal. Additionally, if vision or mobility is an issue, the control panel's size, visibility, and ease of use are essential factors.

You'll also want to consider whether a timer function would be useful for you, and whether you want the option to operate the unit via remote control.

Opting for an oil-filled radiator with different heat settings will allow you more control of the warmth, and a thermostat will ensure that you're not wasting energy. If your heater offers a thermostat, you can set a preferred temperature, and it works to maintain your room at this desired level. If the room starts to drop in temperature, then the thermostat switches the heater into action to maintain the desired temperature, and kicks it off again once the target temperature is reached.

Maintenance is another factor to think about. The good news is that when it comes to how long oil-filled radiators last, we're talking years with very little maintenance.

It's also worth considering the modern alternatives to oil-filled radiators, even if just to confirm that an oil-filled radiator is in fact the right choice for your home.

FAQs

Portable heaters are a great way to keep heating bills low when temperatures drop. The best oil-filled radiators and fan heaters are two of the most popular options, but if you're buying one new, should you opt for an oil-filled radiator or a fan heater?

Choosing the best electric heater on the market is even more important now in light of the latest energy price cap change, which came into effect on 1st January 2025. As Ofgem have rung in the New Year with a 1.2% increase in our energy bills for the next three months (which equates to a £21 increase in average energy bills across the UK), turning the central heating on has become even more of a luxury.

Fortunately, oil-filled radiators and fan heaters could be the saving grace you need to keep your home warm this winter. We've spoken to energy and heating experts and outlined everything you need to know about these two types of heaters, to help you choose which one is right for you.

Oil-filled radiator vs fan heater

Oil-filled radiator vs fan heater: What’s the difference?

Finding the right heater for your home, your family, and your specific needs can sometimes feel like a minefield. But nine times out of ten, you’ll probably whittle down your search to two options; an oil-filled radiator or a fan heater. But what’s the difference, and how do they both work?

Nicholas Auckland, heating expert at Trade Radiators, says, ‘When it's really cold, sometimes the radiator in the room just isn't enough to heat the whole space, so portable heaters are ideal.’ That’s exactly what these two heaters are, but they create heat in very different ways.

An oil-filled radiator is exactly what it says. It’s essentially a radiator filled with thermal oil that’s heated using an electrical element. As the oil heats up, it serves as a convention heater and emits heat through its columns - which are commonly called ‘fins.’

A fan heater is also very simple to understand. This appliance heats a room by passing air over a heat source, which is then pumped into the room.

Oil-filled radiator vs fan heater: Which produces more heat?

When you’re searching for a heater for your home, how much heat it produces is something you need to consider if you want to get the most bang for your buck. After all, the longer you leave the heater on, the more energy it will be using.

In terms of heat production, oil-filled radiators and fan heaters are interchangeable. You’ll find that both appliances come with thermostats and temperature controls that allow you to choose the ideal temperature for the room you’re trying to heat up. This means that you can turn it up as high or turn it down as low as you want, depending on your needs and requirements.

However, there are some distinguishable differences between the two types of heaters, including the speed at which they heat up, how that heat is distributed, and heat retention.

Fan heaters are generally quicker to heat up a room than oil-filled radiators, but they can often struggle with heat distribution. This was something our expert tester, Rachel Ogden, found when she tested the Beldray Flatbed Portable Fan Heater.

She said, ‘For its size, the Beldray fan is a hard worker. Even on its lowest setting, it supplies a good boost of heat instantly. However, that heat has a limited reach and took a while to diffuse around the whole room when tested. Close up, the Beldray is cosy, but it would probably be a costly way to heat a medium-to-large room from cold.’

On the other hand, oil-filled radiators are generally a bit slower to heat up but have a better heat distribution. This could be seen when another one of our expert testers, Rachel Tompkins, tried out the Pro Breeze 2500W 11 Fins Oil Filled Radiator.

‘Sitting next to it in my office, I could feel the heat radiating on my legs within minutes and in less than ten minutes, my office (which measures approximately 2m x 3m) felt warm and cosy,’ she said. ‘This heating performance is streets ahead of others tested, and it had a real impact even on larger rooms, such as a bedroom measuring 4.5 x 3.5 metres.’

While these two heating appliances offer the chance to take the chill away from a cold house, it’s important to note that they’re also very different in terms of heat retention - and this is something you should definitely consider if you’re tightening up the purse strings.

As oil-filled radiators rely on the hot oil inside of the radiator itself, they’ll continue to heat a room until the oil cools down again, which allows you to make the most of extra heat even after you’ve turned it off. This isn’t the case for a fan heater, though.

Nicholas says, ‘Electrical fan heaters have significant heating power, but once they’re off, the space will cool down rapidly as there will no longer be hot air being blown through it.’

This means that if you’re looking to squeeze out a little extra heat for free, an oil-filled radiator will suit you better.

Oil-filled radiator vs fan heater: Which is bigger?

If wondering whether you should be heating your whole house or just the room you’re using and you opt for the latter, a portable heater such as an oil-filled radiator or fan heater is the way to go. As long as you have a plug socket nearby, you can plug either of these heaters into the mains and heat up any room you like.

However, you might want to consider the size of these appliances before you whip out your credit card, as these two heaters are very different.

Fan heaters are generally much smaller than oil-filled radiators, and many of the best fan heaters on the market are a similar size to the best dehumidifiers. This means that they can easily be hidden in cupboards or behind the sofa when you’re not using them. Not only that, but the Russell Hobbs Compact Portable Ceramic Plug-in Fan Heater, available on Amazon is only slightly bigger than your average phone charger.

Oil-filled radiators, on the other hand, are generally much bigger, but this does depend on the number of fins you choose. An oil-filled radiator with 11 fins is usually twice the size of an oil-filled radiator with 6 fins - but this will ultimately affect its heating qualities.

Of course, these fins also make the radiators extremely bulky, making them harder to hide or squeeze into small spaces. Because of this, a fan heater might be more up your street if you have a smaller home.

Oil-filled radiator vs fan heater: Which is more affordable?

If you’re on the lookout for the cheapest electric heater to run, you need to consider two things: the general price of the product and how much it will cost you to run that particular product.

When it comes to the general price of the product, it’s hard to compare oil-filled radiators and fan heaters as they’re fairly similar. The Vonhaus 800W 6 fin Oil Filled Radiator, available on Amazon is the cheapest oil-filled radiator the Ideal Home team has tested, and it has an RRP of £29.99. At the other end of the spectrum, we’ve also tested the De’Longhi 2500W Dragon 4 Oil-Filled radiator, from Argos, which has an RRP of £186.99.

Similarly, you can find good quality fan heaters with very different price points, too. The Beldray Flatbed Portable Fan Heater will set you back just £19.99, but you could also opt for the Duux Threesixty 2 Ceramic Electric Heater, from John Lewis, which retails at £99.99. It’s ultimately a good idea to set your own personal budget to find the best price for you.

But what about running costs? Well, the cost to run an oil-filled radiator can vary depending on the wattage of the device.

On oil-filled radiators, Nicholas says, ‘Cost of running units can vary in size from 500 - 2500 Kw, but at current rates, you’re looking at running costs of approximately 12p - 62p an hour.’

Fan heaters typically use 2kW of power to run, which means they’ll cost around 50p per hour to run on full power. 'So if you used a 2000W fan heater for four hours a day, 7 days a week, it would cost you around £14,' Nicholas explains. 'Whereas an 2500W oil-filled radiator would cost £17.43 to run for the same amount of time.'

When budgeting for either type of heater, factor in the wattage of the device. The higher the wattage, the more it will cost to run, and this is true of both fan heaters and oil-filled radiators.

Final verdict: Which one do you need?

The debate between oil-filled radiators and fan heaters is a difficult one. In terms of buying the appliance and the running costs, these two portable heaters are on a fairly even keel.

In terms of aesthetics and heat distribution, however, these two heaters are very different - and this is where personal preference comes into the picture.

If you live in a smaller house, want a heater that looks a little more sleek and stylish, and want instant heat, a fan heater will tick all of your boxes. However, they're not the most efficient way to heat a house, and you would does have to deal with a lack of heat retention.

But if you have more space in your home and you want to squeeze as much heat out of your portable heater as possible, an oil-filled radiator would definitely suit you better. The impressive heat retention of an oil-filled radiator means that you can get a lot more bang for your buck - but it’s definitely less attractive than a fan heater alternative.

FAQs

Are oil-filled radiators cheaper to run than fan heaters?

In terms of running costs, oil-filled radiators and fan heaters are fairly similar, because of the range of models available. You should expect to pay anywhere between 12p - 62p an hour to run an oil-filled radiator, and a 2kWh fan heater costs around 50p to run.

However, it’s also important to note that oil-filled radiators take longer to heat up, which means that you may have to keep it on for longer than a fan heater. But when you consider the fact that oil-filled radiators retain their heat for much longer than fan heaters, this means that you’ll probably run them for the same amount of time in the end.

'Oil-filled radiators are better suited for longer, more consistent heating,' Les Roberts, energy expert at Bionic confirms. 'The oil inside retains heat, allowing the radiator to cycle off more frequently while still radiating warmth. This makes them more energy-efficient for extended use.'

To work out the running costs for a specific oil-filled radiator or electric heater, use our calculator. All you need to know is the wattage.

Do oil-filled radiators use a lot of power?

Oil-filled radiators vary in terms of power usage, with models ranging from 500 -2500 Kw. They use a lot of power just to get warm in the first place, which is arguably their main drawback.

'The oil inside needs time to warm and it can take a while before the radiator starts to release heat effectively,' Les says. 'While this makes them less suitable for quick warmth, they becomes more efficient for maintaining consistent heat over an extended period once it reaches temperature.'

Oil-filled radiators retain their heat extremely well, which is what makes them economical.

Now you’ve got the lowdown on the oil-filled radiator vs fan heater debate, you should have all of the information you need to stay warm this winter.

Oil-filled radiators are still as popular as ever, especially at a time when temperatures are dropping and we all want to keep energy bills under control. And while these heaters can help you efficiently heat your home, it’s still important to understand how much it costs to run an oil-filled radiator.

Yes, if you’re one of the many homeowners or renters in the UK trying to keep their boiler working to a minimum, the best oil-filled radiators can be a welcome addition to the home. They offer impressive heat output, are portable enough to be moved from room to room, and are generally cheaper to run than the best electric heaters.

But using any heater is going to rack up your energy bills. So, in order for you to work out the costs associated with them, I’ve worked out how much you can expect to spend per hour to run an oil-filled radiator – as well as ways you can reduce your energy bills when using this appliance.

How much does it cost to run an oil-filled radiator?

If you’re looking to find the cheapest electric heater to run, you should definitely consider an oil-filled radiator. But if you want to know exactly how much it costs to run an oil-filled radiator, you need to do some sums.

To work out how much an appliance costs to run, you first need to work out how much electricity it uses. To do this, you should inspect the specifications of the oil-filled radiator you’re looking to buy and find the wattage. Then you can use our calculator to work out how much it will cost to run for an hour, using either the specific price you pay for your energy or, if you aren't sure how much you pay, the current energy price cap.

If you don't have a specific model in mind, then we've worked out some example costs below. As Nicholas Auckland, heating expert at Trade Radiators, explains, ‘The units of oil-filled radiators can vary in size from 500 - 2500W.’ So how much it costs will depend on how powerful your oil-filled radiator is. For example:

• A 500W (0.5kW) model would cost you 13.8p an hour to run.
• A 2500W (2.5kW) model would cost 69.2p an hour to run.

Understandably, the longer you use your oil-filled radiator, the more it will cost. If you have poor insulation or want to heat a large room with this one appliance, it’s likely that you’ll have to keep the heater on for much longer, which will obviously increase the price. Just be wary if you plan to keep an oil-filled radiator on overnight.

However, one major benefit of an oil-based radiator is the oil inside. Jess Steele, heating and technology expert at BestHeating, says, ‘The oil inside retains heat very well, allowing the radiator to continue emitting warmth even after it’s turned off, which means it can effectively maintain a comfortable temperature without consuming excessive energy.’

This means that you’ll always get a little bit of extra warmth for free, allowing you to keep heating your home without actually turning the heating (or your oil-filled radiator) on.

How can I cut the cost of an oil-filled radiator?

While it’s fairly cheap to run an oil-filled radiator, I understand that many people still worry about rising energy bills. So, it’s worth looking at ways to cut the costs of running this appliance, and a key part of this is to make sure you are using your oil-filled radiator most efficiently.

1. Choose the right size

One of the things everyone should know before buying an oil-filled radiator is that size really does matter. And while it’s important to choose one with the right dimensions, you also need to consider size in terms of the power output. Especially if you want to use your oil-filled radiator in a large room.

If you want to heat a larger room, you need to choose an oil-filled radiator that has a higher wattage. It’s generally considered that a 600W radiator will successfully heat a small 6m2 room, a 1000W will heat a 10m2 room, and a 2500W will heat a 25m2 room. If you don’t choose the right size, you’ll have to keep your oil-filled radiator on for longer to feel the benefits - and this will ultimately cost you more in the long run.

2. Make the most of built-in controls

There are many different oil-filled radiators out there, all with different controls. At the cheaper end of the spectrum, you have radiators that come with a simple on/off switch. However, there are others that offer a range of buttons and programs, including timers and temperature gauges.

Nicholas says, ‘Electric oil-filled radiators may also offer programmable heating controls that give you the flexibility to create a heating routine tailored to your needs. This ensures you are achieving an optimal temperature when it is needed and preventing heat from being wasted in unused space, which can happen when turning on the central heating for the entire home.’

3. Keep things stable

Of course, I understand that this isn’t always possible, but one of the best ways to cut the costs of an oil-filled radiator is to keep the temperature as stable as possible in your house. If the temperature drops too low, your appliance will have to work extra hard to warm up the room again - which will cost you more money in the long run.

Katie Lilywhite, heating expert at AO.com, suggests, ‘To keep costs down, pre-heat your room by turning the radiator on for a quarter of an hour before you need the space warm. Close all doors and avoid blocking the radiator – good airflow will ensure it heats your room efficiently.’

4. Clean it regularly

Everyone probably knows how important it is to clean your radiators, but fewer people realise that cleaning an oil-filled radiator can also reduce the running costs. That’s because a build-up of dust can create a protective ‘layer’ around the fins, which means it’ll take longer to heat up a room. This means you’ll have to keep it on for longer.

Dusting your oil-filled radiator is good practice, anyway. And while oil-filled radiators are generally one of the safest electric heaters out there, it’s still worth keeping any electric items free from dust and debris that could pose a safety risk.

Kept well, oil-filled radiators will last for years.

5. Take extra measures

Ultimately, there’s no use in using an oil-filled radiator if you have a poorly insulated, leaky house. As soon as you turn the oil-filled radiator on, the heat will be lost through draughty doors and windows, cracks in walls, and even a poorly insulated roof.

So, to cut the running costs of an oil-filled radiator, it’s also a good idea to put in place some DIY draught-proofing measures to prevent any heat loss. Using something as simple as this Weather Stripping Tape, £9.99 at Amazon, can work wonders. Then, you won’t have to keep your oil-filled radiator on as long.
