Ideal Home’s reviewer tested Dreo’s 2000W Smart Whole Room Heater 720S for 10 days, reporting that it can direct heat toward a person or distribute it around a room. In the test, it raised the temperature in an 18-square-metre living room by 4°C in 10 minutes; results varied in a larger kitchen-diner.
Ideal Home has published a 10-day test of Dreo’s Smart Whole Room Heater 720S, a 2000W ceramic fan heater that switches between directing warmth toward a person and distributing heat in a 360-degree pattern. The reviewer reported a 4°C rise in an 18-square-metre living room over 10 minutes, while the temperature in a larger kitchen-diner rose by 2°C over 20 minutes.
The reviewer tested the heater in the living room and kitchen-diner of a 1970s three-bedroom home. The 720S has three heat settings—1100W, 1400W and 2000W—along with Eco and fan-only modes. In Eco mode, users can set a target temperature between 5°C and 35°C, and the heater adjusts its output in response to the target and room temperature, according to the review.
A button switches between focused heating, which sends warm air from the front grille, and whole-room mode. In the latter, the upper section rises by about four centimetres and sends airflow in all directions. The reviewer said the focused setting was also effective and that the unit was light enough to reposition by hand. It does not oscillate.
The heater weighs 3.1 kilograms and measures 22 by 30 by 22 centimetres. It can be controlled using its onboard panel, a remote or the Dreo app, and the review says it works with Google Home and Alexa. The product also has adjustable ambient lighting and listed safety features including tip-over and overheat protection, a child lock and cool-touch housing. Ideal Home lists a recommended retail price of £119.99.
Two Heating Patterns in One Unit
The 720S’s key selling point is that it can serve two different needs: personal warmth at close range or broader air distribution when heating a room. That flexibility may appeal to people who want a portable heater for a desk or seating area but also want to use it in a shared space. The review’s separate room tests offer a practical indication of performance, while also showing that results depend on room size and setup.
The reviewer found that the whole-room mode worked faster in the smaller living room than in the larger kitchen-diner. The test does not establish how the heater would perform across different house layouts, insulation levels or outdoor temperatures. Its 2000W maximum output and estimated running cost also matter to household budgets: Ideal Home gives a figure of 53 pence per hour, based on the October 2026 energy price cap, rather than a universal cost for every tariff or setting.

How the Home Test Was Conducted
The report is a product review, not an announcement of a new heating standard or independent laboratory trial. Ideal Home’s reviewer used the heater for 10 days across two rooms measuring 18 square metres and 22 square metres. The article says the product launched at the end of September, but does not specify the year of that launch in the supplied material.
For the whole-room test, the reviewer placed the heater on a round console table and moved it farther into the room rather than leaving it against a wall. The review notes that the unit still needs a wall socket, which can limit placement and leave a cable across the floor. It also recommends carrying the heater by its side handle, as indicated by a warning sticker on the packaging.
“I loved this switch, and I even did a bit of a giddy giggle when I tried it for the first time.”
— Ideal Home reviewer Sarah Handley
Limits of the Performance Evidence
The reported temperature changes come from one reviewer’s home test; the source does not describe controlled laboratory conditions or provide measurements from other homes. It is not clear how room insulation, ceiling height, starting temperatures or the placement of the heater affected the results. The article also does not provide a comparative test against other heaters.
The listed 53p-per-hour running cost is tied to the October 2026 energy-price cap and should not be treated as a fixed charge for every household. Actual costs depend on tariff rates and how the heater is used. The supplied report does not give a measured annual cost or confirm the product’s current availability and price beyond its stated £119.99 recommended retail price.
Check Price and Room Suitability
Readers considering the 720S can compare its current price with the review’s £119.99 recommended retail price and check the product’s stated suitability for rooms up to 25 square metres. The test covered rooms below that limit, measuring 18 and 22 square metres; it did not verify performance in a 25-square-metre room.
Before buying, users may also want to check their electricity tariff and think about where the heater can sit near a wall socket without creating a cable hazard. The source provides no later test results or manufacturer update, so further information about availability, current pricing and performance in other homes remains unreported.
