Whether you want to heat the whole room, or just yourself, this Dreo electric heater offers the best of both worlds
I've been using the Dreo Smart Whole Room Heater 720S daily
Effortlessly switching between 360° heat distribution or more targeted focused heat, the Dreo Smart Whole Room Heater 720S works quickly to warm your space. I loved how simple it was to use, including it's smart functionality, and that set up was just as straightforward. While it's powerful enough to heat spaces up to 25m2, it won't be enough to adequately heat rooms larger than that.

As temperatures drop into single figures, I feel very fortunate that I get to spend my chilly days testing heating products.
When it comes to the best electric heaters, I know what I'm looking for. I want quick and even heat from a product that is easy to use, doesn't take up too much space and that I can move around my home easily. It gets bonus points if it also looks good when it's on display.
After being impressed with a couple of Dreo's cooling products over the summer, I was excited to get my hands on their new heater offering, the Smart Whole Room Heater 720S. This is how it fared when I used it in my home, and whether I think it's worth the money.
In a nutshell
Launched at the end of September, the Dreo Smart Whole Room Heater 720S is a 2000W electric heater capable of delivering targeted warmth right in your direction, or 360° airflow to warm the whole room with the click of a button.
With three heat levels, plus Eco and fan only modes, and a temperature range from 5-35°C, you can customise this heater's output to your personal preference levels using the on-board, control panel, simple remote or easy-to-navigate Dreo app.
As with some other products in the Dreo range, the 720S features colour changing ambient light that you can adjust in the app, as well as eight different safety features, including tip over protection, a child lock, cool-touch housing and overheat protection.
The 720S from Dreo can heat rooms up to 25m2 quickly thanks to its 360° air distribution. With the press of a button you can switch the air flow to be directed solely at you instead.
How I tested
As well as being Ideal Home's Renovation Editor, I also look after all of the websites Home Energy content, which means I'm well versed in what it takes to keep your home warm in winter and how you can do that in the most energy efficient way possible. I tested the Dreo Smart Whole Room Heater 720S in the living room and kitchen-diner of my 1970s three-bed home for 10 days. Find out more about how we test electric heaters.

Unboxing, setting up and first impressions
Arriving in a not-to-heavy cardboard box, it was really easy to carry the Dreo 720S into my living room to be unpacked with the 'help' of my dog Blossom. The packaging in largely cardboard, with a recycled plastic bag around the heater itself, another around the remote control and batteries, and final bit of plastic covering the prongs of the plug.
My instinct was to lift the heater out of the box by the top, but thankfully there was a bright yellow sticker advising to use the leather handle a little way down the side instead (it will become clear later on as to why this is the case).
Once it was out of the box, I could have a good look. It feels a bit beefier than some other heaters I've tested, but it could definitely still sit on a table top without looking top heavy.
There's no assembly required beyond fitting the batteries in the remote control, so it is just a matter of positioning it where you want it, plugging it in, and you're ready to go after a couple of minutes.
If you want to use the Dreo app to control it, then this might take you a couple of minutes to download the app and create an account. But as I already had the app after testing other smart Dreo products over the summer, it look less than 10 seconds to connect it.
What’s it like to use?
The Dreo 720S is nice and simple to use, however you choose to operate it. You can cycle through three different heat modes, ranging from 1100W (H1), 1400W (H2) and 2000W (H3), through to Eco mode, where you can choose a target temperature and the heater will automatically adjust its output based on the target and ambient temperatures.
With the press of one button, you can switch between focused heating mode (where the heat comes from the grille on the front of the heater) to whole room heating where the top of the heater raises up about 4cm and theynstarts distributing heat in all directions. I loved this switch, and I even did a bit of a giddy giggle when I tried it for the first time.
In whole room mode, the heater managed to increase the temperature in my 18m2 living room by 4°C in just 10 minutes. It took longer to warm my 22m2 open plan kitchen diner, increasing the temperature by 2°C in 20 minutes. For maximum benefit of the whole-room heat function, I popped it on a round console table and pulled it further into the room, rather that having it pushed against the wall.
It makes more sense to me that you will feel the benefit more if the heater is more centrally in the room, but as it needs to be plugged into a wall socket, you are limited on how centrally you can position it, and it does mean you have a trailing cable that you'd need to be mindful of when moving around.
When it comes to the focused heating setting, it's just as effective, and even though it doesn't oscillate, it's lightweight enough to tweak into the perfect position. While it will automatically switch off if you pick it up by the handle during use (thanks to its tip over protection), you can gently manoeuvre it thanks to it's cool touch housing on its body that stays cool, no matter now long the heater has been on (the grille does get hot though).
Moving the heater from room to room is easy to do single handedly, thanks to the leather-look handle on the back and it's light weight.
In terms of noise, it's very quiet in H1 mode, measuring just 35dB on my decibel meter (which is the equivalent of a whisper). It topped at 53dB in H3 mode, which is like gentle background noise. It's noticeable, but I didn't find it too bothersome. I didn't find I needed to adjust the volume on the TV when it was in this mode, and it wasn't too distracting while I was working.
I ended up using the app to control the heater more than the onboard control panel or the remote control, largely because I tend to always have my phone on me. I like that it meant I could turn the heater on to warm up the space before I needed to use it (it's possible to create on/off schedules in the app too, although I tend to use the heater more adhoc than that). I also like that I can adjust the ambient light feature in the app — my preference is cycle, which gentle moves through the five colour options, but there are three other options to choose from, including an indicator mode, where the colour changes depending on the ambient temperature in the room.
What are the running costs like?
Depending on the mode you choose, the Dreo Smart Whole Room Heater 720S will cost between 29 and 53p per hour to run, based on the October 2026 energy price cap.
But to help keep those costs as low as possible, you can use the Eco mode, which will automatically adjust the output levels depending on the ambient temperature in the room. In the app, there is also the option to enable Open Window Detection that will notify you if it senses a sudden drop in the ambient temperature while the heater is in heat or eco mode.
Cleaning and maintenance
As with any electric heater, it's important to keep them dust-free to ensure they work at their most optimum and efficient level. So a regular dust with a dry cloth is all that's really needed.
I'd say a more important factor is to always be wary of how you carry and store the heater. Lifting it by the head (or storing it where this can be inadvertently damaged), could mean that you lose the whole room air distribution functionality could be compromised.
Who should buy the Dreo Smart Whole Room Heater 720S?
I think the Dreo Smart Whole Room Heater 720S will suit most homes and requirements. It's easy to use, quick to heat, and the whole room/focused heating switcheroo is really handy. It's not the most affordable though, with a price tag in excess of £100 (although I do think it's worth every penny).
For something more affordable, we highly rate the Dreo Atom 316 which, although more simple in it's functionality and best in spaces under 20m2, will still get the job done. Similarly, the Morphy Richards HeatFlux 1.5kW Ceramic Fan Heater is another affordable alternative.
If the 360° air flow is what tempts you to this model, but you need to heat a larger space, then you should also check out the Duux Threesixty 2, which is capable of heating rooms up to 30m2.
