Dreo’s Smart Whole Room Heater 720S is a 2,000W ceramic fan heater with modes for circulating heat around a room or directing it toward one person. In a 10-day Ideal Home test, it raised the temperature of an 18-square-metre living room by 4°C in 10 minutes; results will vary by room and conditions.
Dreo’s Smart Whole Room Heater 720S can switch between directing warmth toward a person and distributing heat in 360 degrees, according to a review published by Ideal Home. The 2,000W ceramic fan heater was tested in two rooms for 10 days, with the reviewer recording a 4°C rise in a 18-square-metre living room over 10 minutes in whole-room mode.
The heater offers three power settings: 1,100W, 1,400W and 2,000W. It also has an Eco mode, where users set a target temperature and the unit adjusts its output, and a fan-only mode. Its stated temperature range is 5°C to 35°C. The controls are on the unit, on a supplied remote, or in Dreo’s app; the company says the heater works with Google Home and Alexa.
Ideal Home’s tester used the 720S in the living room and kitchen-diner of a 1970s three-bedroom home. In the 22-square-metre open-plan kitchen-diner, the temperature rose by 2°C over 20 minutes in whole-room mode. The reviewer said placing the heater farther into the room, rather than against a wall, helped make use of the all-direction airflow. Its position is still limited by the need to plug it into a wall socket.
The unit weighs 3.1 kilograms and measures 22 by 30 by 22 centimetres, according to the published specifications. Ideal Home lists a recommended room size of up to 25 square metres and a recommended retail price of £119.99. It also lists an estimated running cost of 53 pence per hour, based on the October 2026 energy price cap. That figure is an estimate tied to the stated tariff basis, not a guaranteed cost for every household.
Two Heating Modes, One Portable Unit
The 720S’s main distinction is that it combines personal, directional warmth with a mode intended to spread heat around a room. That may give users more flexibility than a heater designed only to blow heat forward, particularly when moving between working at a desk and warming a shared space.
The test results offer a practical indication of performance, but not a promise of the same temperature change in every home. Room size, insulation, starting temperature, heater placement and airflow can all affect how quickly a space warms. The review also points to a trade-off: whole-room coverage can require a more central position, while the cable limits where the heater can be placed.
For shoppers comparing electric heaters, the stated 53-pence hourly estimate is relevant alongside the purchase price and output. Actual electricity costs depend on the household’s tariff and how the heater is operated. The Eco setting may reduce or vary output against a temperature target, but the source does not report measured energy savings from using it.

What the 10-Day Test Covered
Ideal Home describes the 720S as a product launched at the end of September. Its reviewer tested it for 10 days in a living room and kitchen-diner, rather than conducting a controlled comparison against other heaters. The published account gives temperature changes in those rooms but does not identify a standardised test protocol or report a full set of measurements across different starting conditions.
The heater is a ceramic fan model with no oscillation listed in its specifications. For targeted heating, it sends air through the front grille. In whole-room mode, the upper section rises about four centimetres and the unit distributes air around it. The review also describes colour-changing ambient lighting, adjustable in the app, and features including tip-over protection, a child lock, cool-touch housing and overheat protection.
These details come from the Ideal Home review and its product specifications. The reported temperature gains are the reviewer’s observations in a particular home; they should not be treated as independent laboratory results or a guarantee of performance in other spaces.
“The heater managed to increase the temperature in my 18m2 living room by 4°C in just 10 minutes.”
— Ideal Home reviewer Sarah Handley
Performance Beyond One Home
The review does not establish how the heater performs across different home layouts, insulation levels or weather conditions. It also does not provide a comparison with competing models, independent laboratory measurements, or a measured assessment of energy use in each mode. The temperature increases are observations from one 10-day test, not a universal benchmark.
The source lists a 53-pence hourly running-cost estimate based on the October 2026 energy price cap. The amount an owner pays will depend on their electricity tariff and operating pattern. The report does not give a separate cost for Eco mode or confirm how frequently the heater would cycle to maintain a selected temperature.
Although the review lists several safety features, it does not describe tests of each one. Readers should follow the product instructions and keep the heater clear of items that could obstruct airflow or catch fire. The source material does not state whether the 720S is currently available from every retailer or whether its listed price has changed since launch.
Check Price and Local Availability
The source provides a £119.99 recommended retail price but does not report a later price update or a follow-up test. Shoppers considering the unit will need to check current retailer listings and compare the price with their local electricity costs and room-heating needs.
Any further evidence about performance would need to come from additional testing in other rooms or a direct comparison with similar heaters. Until then, the review supports a narrower conclusion: the 720S offers two airflow modes, and it warmed the two spaces tested at different rates. Its results elsewhere remain uncertain.
Key Questions
What is the Dreo Smart Whole Room Heater 720S?
It is a 2,000W ceramic fan heater with focused and 360-degree whole-room airflow modes, plus Eco and fan-only settings.
How quickly did it warm the tested rooms?
In Ideal Home’s test, the temperature in an 18-square-metre living room rose 4°C in 10 minutes. In a 22-square-metre kitchen-diner, it rose 2°C in 20 minutes. These were results in the reviewer’s home, not guaranteed outcomes.
Can the heater be controlled remotely?
Yes. The published specifications list control through the Dreo app and a supplied remote, as well as controls on the heater. The source also lists compatibility with Google Home and Alexa.
How much does the Dreo 720S cost to run?
Ideal Home lists an estimated cost of 53 pence per hour, based on the October 2026 energy price cap. A household’s actual cost will depend on its electricity tariff and how the heater is used.
What safety features does it have?
The review lists tip-over protection, a child lock, cool-touch housing and overheat protection, among eight stated safety features. Users should follow the manufacturer’s instructions and keep the heater’s airflow unobstructed.
