Ideal Home reviewer Sarah Handley tested Dreo’s 2000W Smart Whole Room Heater 720S at home for 10 days. The heater switches between directing warmth toward a person and distributing heat around a room; in her tests, it raised the temperature of an 18-square-metre living room by 4°C in 10 minutes.
Ideal Home has published a 10-day home test of Dreo’s Smart Whole Room Heater 720S, a 2000W ceramic fan heater that switches between directing warmth forward and distributing heat through 360-degree airflow. Reviewer Sarah Handley found that it raised the temperature in her 18-square-metre living room by 4°C in 10 minutes; that result is from her test, not a guarantee for other rooms or homes.
The 720S offers three heat settings: 1100W, 1400W and 2000W. It also has an Eco mode, which lets users set a target temperature so the heater can adjust its output, and a fan-only mode. The stated temperature range is 5°C to 35°C. Controls are available on the unit, through a remote, or in Dreo’s app; the product works with Google Home and Alexa.
Handley tested the heater in the living room and kitchen-diner of her 1970s three-bedroom home. In the 18-square-metre living room, she recorded a 4°C rise over 10 minutes using the whole-room mode. In the larger, open-plan 22-square-metre kitchen-diner, the temperature rose by 2°C over 20 minutes. These are observations from one home and test period; the source does not provide details such as starting temperatures or the conditions needed to reproduce the results.
The heater weighs 3.1kg and measures 22 by 30 by 22 centimetres. Ideal Home lists a recommended room size of up to 25 square metres and a UK retail price of £119.99. The review also describes app-adjustable ambient lighting and safety features including tip-over and overheat protection, a child lock and cool-touch housing. The source lists an estimated running cost of 53p per hour, based on the October 2026 energy price cap; actual costs depend on electricity rates and how the heater is operated.
One Heater, Two Heat Patterns
The product’s central distinction is its choice between personal, directed warmth and air distribution around a room. That could make it useful for people who want to warm the area they occupy without directing heat everywhere, or who want to heat a small room more broadly. The review’s measurements suggest the whole-room mode raised temperatures in both test spaces, although the size and speed of any change will depend on room conditions.
That flexibility does not establish that a portable electric heater will be cheaper than central heating or other heating options. The published 53p-per-hour estimate is tied to an energy-price assumption, and the heater’s selected power level and operating time affect consumption. Readers considering running costs should compare current electricity prices and use patterns rather than treating the figure as a fixed bill.
Placement also matters to the reviewer’s experience. Handley found the whole-room mode worked best when the heater was brought farther into the room, but it still needs a wall socket. That can limit positioning and leave a cable across a walking route. Its low weight makes it easier to move, but users still need to position the unit and cord safely.

How the Home Test Was Conducted
The report is a product review by Ideal Home, not a controlled laboratory comparison. Handley says she tested the heater for 10 days in two areas of her own home. She also notes that she had previously tested Dreo cooling products, and already had the company’s app installed, which made connecting the heater take less than 10 seconds for her. A new user may need extra time to download the app and create an account.
The report says the 720S launched at the end of September, but does not identify the year in that wording. Its listed dimensions, modes, compatibility and safety features describe the product; the temperature changes are the reviewer’s results in particular rooms. They should not be read as independent performance testing across different homes, climates or room layouts.
“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.”
— Sarah Handley, Ideal Home reviewer
Performance Beyond Two Rooms
The published results do not establish how quickly the 720S will heat other rooms. Ideal Home reports temperature changes in two spaces, but does not state their starting temperatures, outdoor conditions, ceiling heights, insulation levels or whether other heat sources were operating. The 4°C and 2°C readings are therefore specific to Handley’s home and testing, not a promise of the same outcome elsewhere.
The source also does not provide a side-by-side comparison with other heaters or independent measurements of energy use. It lists an estimated hourly cost using an October 2026 price-cap basis, but does not say how that figure was calculated for each operating mode. The launch year is not specified, and the report excerpt does not establish current stock or pricing beyond the listed recommended retail price.
Check Current Price and Ratings
The source provides a completed review rather than a scheduled product update or follow-up test. Readers considering the heater can check Dreo or retailer listings for current availability and price, since the £119.99 figure is the report’s stated recommended retail price. They can also compare the stated room-size rating and modes with their own room layout and heating needs.
Before relying on a portable heater for regular use, readers should check its operating instructions, keep it on a stable surface, and avoid placing it where the cable creates a trip hazard. The review describes built-in safety features, but it does not provide a separate assessment of their performance or specify how the product compares with applicable safety standards.
Key Questions
What is the Dreo Smart Whole Room Heater 720S?
It is a 2000W ceramic fan heater with a forward-facing focused mode and a 360-degree whole-room mode. The report lists three heat levels, Eco and fan-only modes, app control, and compatibility with Google Home and Alexa.
How well did it heat the rooms in the review?
In Sarah Handley’s home test, the temperature in an 18-square-metre living room rose by 4°C in 10 minutes. In a 22-square-metre kitchen-diner, it rose by 2°C in 20 minutes. Those figures describe her test conditions and are not guaranteed results for other rooms.
What does the Dreo 720S cost to run?
Ideal Home lists an estimated cost of 53p per hour, calculated using the October 2026 energy price cap. The actual cost will vary with electricity tariffs, selected heat setting and use; the report does not provide a separate cost for each mode.
Can the heater be controlled remotely?
Yes. The report says the 720S can be operated using its onboard controls, remote control or Dreo app, and that it works with Google Home and Alexa. A user setting it up for the first time may need to download the app and create an account.
What safety features does the review list?
The report lists tip-over protection, a child lock, cool-touch housing and overheat protection, among eight stated safety features. It does not detail every feature or report independent tests of them; users should follow the product instructions and keep the heater and its cord safely positioned.
