Ideal Home tested Dreo’s 720S, a 2,000W ceramic fan heater that switches between focused heat and 360-degree room distribution. In the reviewer’s home, it raised the temperature of an 18-square-metre living room by 4°C in 10 minutes; results varied by room size and placement.
Dreo’s Smart Whole Room Heater 720S can direct heat toward one person or switch to 360-degree airflow intended to warm an entire room, according to an Ideal Home review based on 10 days of home testing. The 2,000W ceramic fan heater offers a practical distinction for people choosing between personal warmth and broader room heating, though the reviewer’s temperature results differed between rooms.
Ideal Home’s reviewer tested the heater in the living room and kitchen-diner of a 1970s three-bedroom home. In whole-room mode, the temperature in the 18-square-metre living room rose by 4°C in 10 minutes. In the larger, open-plan 22-square-metre kitchen-diner, it rose by 2°C over 20 minutes. Those are results from one home, not a guarantee of performance in other rooms.
The reviewer said the best results came when the heater was placed on a round console table and moved farther into the room, rather than pushed against a wall. That positioning can be harder in practice because the unit needs a wall socket, and a cable trailing across a room can create an obstacle. The heater weighs 3.1kg and measures 22 by 30 by 22 centimetres, according to the review.
Users can select three heat settings: 1,100W, 1,400W and 2,000W. Eco mode lets users set a target temperature, with the heater adjusting its output according to that target and the ambient temperature. It also has a fan-only mode and a selectable temperature range of 5°C to 35°C. Controls are available on the unit, through a remote or in the Dreo app; the review says it also works with Google Home and Alexa.
Two Heating Patterns in One Unit
The 720S’s main selling point is that it offers focused warmth and room-wide distribution from the same portable heater. A person working at a desk or sitting nearby can direct heat toward themselves; switching modes lets the unit spread warmth around a space instead. That flexibility may suit households that use the same room in different ways during the day.
The test results also show why “whole room” performance should be read with room size and setup in mind. The reviewer recorded a larger temperature rise in the smaller living room than in the open-plan kitchen-diner, despite using the same heater. Consumers should not treat those figures as a promise for their own homes: room layout, starting temperature, insulation and where the heater can safely sit may affect the outcome.
The model’s listed retail price is £119.99. The review gives an estimated running cost of 53 pence per hour, calculated using the October 2026 energy price cap. That is a source-provided estimate tied to that tariff period and heater use; actual costs depend on electricity rates and how the unit is operated.

What the Home Test Covered
Ideal Home says the 720S launched at the end of September and describes the product as a 2000W ceramic fan heater rated for rooms up to 25 square metres. Its review is based on 10 days of use in two spaces in the reviewer’s home. The source does not provide the year of the launch or a full account of how temperature readings were taken, so the reported results are best understood as a household test rather than a controlled laboratory comparison.
The mode change is mechanical as well as a change in airflow: in whole-room mode, the top of the heater rises by about 4 centimetres to distribute air in all directions. In focused mode, heat comes from the front grille. The reviewer found the unit easy to operate and move, while noting that its position is constrained by the need to plug it into a socket.
Dreo lists several safety features, including tip-over protection, a child lock, cool-touch housing and overheat protection. The source says the heater switches off if lifted by its handle during use. These features do not remove the need to follow the product instructions, keep the appliance clear of obstructions and use it with care around children and pets.
“In whole room mode, the heater managed to increase the temperature in my 18m2 living room by 4°C in just 10 minutes.”
— Ideal Home reviewer Sarah Handley
Limits of the Reported Results
The source does not say what year the heater launched, and the supplied review material does not establish whether the 720S is available in every market or whether its price has changed since publication. The £119.99 retail price and estimated hourly cost should be checked against current retailer listings and electricity tariffs.
The reported temperature changes come from one home and two rooms. The review does not provide a standardized comparison with other heaters, a detailed account of measurement equipment or results across different insulation levels and starting temperatures. It is also not clear how much energy the appliance used during the 10-day test. Readers should treat the results as one reviewer’s observations, not a universal heating estimate.
Check Price and Room Fit
Readers considering the 720S can compare its current price and availability with other electric heaters, then check whether its stated 25-square-metre room rating matches the space they want to heat. The review suggests that placement affects the experience, but the power cord may limit how centrally the unit can be positioned.
Before use, buyers should consult the manufacturer’s instructions for placement, clearances and safety features. Further independent testing across more room sizes and conditions would help establish how consistently the heater performs beyond the reviewer’s home; the source provides no such additional results.
Key Questions
Can the Dreo 720S heat one person or a whole room?
According to Ideal Home, it has a focused mode that directs warmth from the front grille and a whole-room mode that raises the top of the unit to distribute airflow in 360 degrees.
How quickly did it warm the rooms in the review?
In the reviewer’s home, the temperature rose by 4°C in 10 minutes in an 18-square-metre living room, and by 2°C in 20 minutes in a 22-square-metre kitchen-diner. The figures are specific to that test.
What controls and settings does the heater have?
The 720S has three heat levels—1,100W, 1,400W and 2,000W—plus Eco and fan-only modes. It can be operated using controls on the unit, a remote or the Dreo app, and the review lists Google Home and Alexa compatibility.
How much does the Dreo 720S cost to run?
Ideal Home estimates 53 pence per hour, using the October 2026 energy price cap as its basis. The actual cost depends on the user’s electricity tariff and how the heater is operated.
What safety features are listed?
The review lists tip-over protection, a child lock, cool-touch housing and overheat protection. Users should still follow the manufacturer’s instructions and keep the heater positioned safely.
