Ideal Home reviewed Dreo’s Smart Whole Room Heater 720S, a 2000W ceramic fan heater that switches between directing heat forward and distributing it around a room. In a 10-day home test, the reviewer recorded a 4°C rise in an 18-square-metre living room in 10 minutes; results in a larger kitchen-diner were slower.
Ideal Home has reviewed Dreo’s Smart Whole Room Heater 720S, a 2000W ceramic fan heater that can direct warmth toward a person or send air in a 360-degree pattern around a room. The reviewer tested it for 10 days in two areas of a home and recorded different warming results depending on the room’s size, offering a practical look at the device’s advertised flexibility rather than a guarantee of performance in every home.
The 720S switches between focused heating, with air coming through the front grille, and whole-room mode, in which the top section rises by about 4 centimetres to distribute heat in all directions. In Ideal Home’s test, the reviewer used whole-room mode in an 18-square-metre living room; the measured temperature increased by 4°C in 10 minutes. In a 22-square-metre open-plan kitchen-diner, it rose by 2°C in 20 minutes. These are results from one home test, not independent laboratory measurements or a promise of the same result in other conditions.
The heater has three power settings: 1,100W, 1,400W and 2,000W, 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 ambient temperatures, according to the review. Controls are available on the unit, through a remote, or in the Dreo app. The source says the device works with Google Home and Alexa.
Ideal Home lists the model at £119.99, with a weight of 3.1 kilograms and dimensions of 22 by 30 by 22 centimetres. The reviewer said setup required no assembly beyond putting batteries in the remote. The heater has no oscillation, but the reviewer found it light enough to reposition manually. Its listed safety features include tip-over protection, a child lock, cool-touch housing and overheat protection.
One Heater, Two Heating Patterns
The defining feature is the ability to choose between warming a person directly and circulating heat around a room. That could make the 720S useful for different situations: focused warmth when someone is seated nearby, or wider distribution when a room is in use. The review’s measurements suggest the roomwide mode can raise temperatures in a modest-sized room quickly under the tested conditions, while the larger space warmed more slowly.
The distinction matters for shoppers comparing portable heaters because a heater’s wattage alone does not tell them how evenly or quickly a room will feel warmer. Placement also affected the reviewer’s experience: moving the unit farther into the living room improved its position for distributing heat, but the need for a wall socket limited how centrally it could sit. That trade-off between air distribution and outlet location is relevant to everyday use, especially where a trailing cable could cross a walking route.
The stated running-cost figure in the review is 53 pence per hour, calculated using the October 2026 energy price cap. That is a source-specific estimate, not a universal cost: actual expense will depend on the applicable electricity tariff, chosen setting and how long the heater runs. The supplied material does not establish that this heater will lower household energy bills or use less energy than another heating method.

How the Home Test Was Done
The report is a product review by Ideal Home’s Renovation Editor, who also covers the publication’s home-energy content. The reviewer tested the Dreo 720S for 10 days in the living room and kitchen-diner of a 1970s three-bedroom home. The source says the model launched at the end of September but does not identify the year in the supplied text.
The reviewer describes a 2000W ceramic fan heater with a maximum stated room size of 25 square metres. The test covered an 18-square-metre living room and a 22-square-metre open-plan kitchen-diner, both within that stated limit. The review reports temperature changes in those rooms, but the supplied material does not detail the measurement equipment, starting temperatures, outdoor conditions or whether other heat sources were operating.
In the living room, the reviewer placed the heater on a round console table and pulled it farther into the space for the whole-room test. The account notes that the unit must remain plugged into a wall socket, which can limit placement. Its compact dimensions and 3.1-kilogram weight were presented as practical features for moving it between rooms, while the lack of oscillation means users need to reposition it manually when using focused mode.
“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.”
— Ideal Home reviewer Sarah Handley
Performance Beyond One Home
The reported temperature changes come from one reviewer’s home test. The source does not provide enough detail to determine how the readings were taken or to isolate the effects of room insulation, ceiling height, initial temperature, outdoor weather or other heating. Results in other homes may differ, and the figures should not be treated as standardized comparisons with competing heaters.
The supplied review excerpt does not confirm how well the app, Google Home or Alexa integrations worked over the full test, nor does it give detailed results for Eco mode, fan-only operation, noise, long-term durability or electricity use at each setting. It lists eight safety features, but the excerpt names only some of them. The source also does not specify the year for the reported launch or the review’s publication date, so that timing cannot be pinned down more precisely.
Check Price and Room Fit
The review presents the 720S as a product for shoppers considering portable electric heat, but the supplied material does not report a later product update, a new test or a change in availability. Readers weighing a purchase can compare the listed £119.99 price and 53-pence-per-hour estimate with current retailer information and their own electricity tariff. They should also check the manufacturer’s room-size guidance and leave the heater positioned according to its instructions, with its power cable kept clear of walkways.
Any assessment of real-world running costs will depend on the selected mode, target temperature, usage time and home conditions. The available report does not establish whether the 720S is more economical than central heating or other portable heaters. Further independent testing across homes and room types would be needed to make broader performance comparisons.
Key Questions
What does the Dreo 720S do differently?
It switches between front-directed heat for a person nearby and a raised-top setting that sends warm air in a 360-degree pattern around the room.
How quickly did it warm the rooms in the review?
In Ideal Home’s test, the 18-square-metre living room rose by 4°C in 10 minutes. The 22-square-metre kitchen-diner rose by 2°C in 20 minutes. These were results in one home under conditions the supplied excerpt does not fully describe.
How much does the heater cost to run?
Ideal Home lists an estimated cost of 53 pence per hour, based on the October 2026 energy price cap. Actual costs vary with electricity tariffs, settings and usage time.
Can the Dreo 720S be controlled remotely?
The review says it can be operated with the supplied remote or the Dreo app, and lists compatibility with Google Home and Alexa. The supplied excerpt does not give detailed test results for those integrations.
What safety features are listed?
The source lists tip-over protection, a child lock, cool-touch housing and overheat protection, among eight stated safety features. The excerpt does not name the other four.
