Ideal Home reviewer Sarah Handley tested Dreo’s Smart Whole Room Heater 720S for 10 days, using its adjustable airflow for either focused warmth or 360-degree room heating. In her tests, it raised an 18-square-metre living room’s temperature by 4°C in 10 minutes; warming a 22-square-metre kitchen-diner by 2°C took 20 minutes. Those are results from one home, not a guarantee of performance in other rooms.
Ideal Home reviewer Sarah Handley tested Dreo’s Smart Whole Room Heater 720S for 10 days, reporting that the 2000W ceramic fan heater can direct warmth toward a person or distribute it in 360 degrees around a room. In her home tests, it raised the temperature of an 18-square-metre living room by 4°C in 10 minutes, while a larger open-plan kitchen-diner warmed more slowly.
The heater switches between focused heating, which sends air through its front grille, and whole-room mode, in which its top section rises by about 4 centimetres to distribute heat in all directions. Handley said she found the switch straightforward to use. The unit does not oscillate, but she reported that its 3.1-kilogram weight made it easy to reposition by hand.
In whole-room mode, the reviewer measured a 4°C rise in 10 minutes in her 18-square-metre living room. In a 22-square-metre kitchen-diner, the temperature rose by 2°C over 20 minutes. She said she moved the heater farther into the room for the latter test, while noting that the need for a wall socket limits placement and can leave a trailing power cable.
The 720S has three heat settings—1,100W, 1,400W and 2,000W—as well as Eco and fan-only modes. Its thermostat can be set between 5°C and 35°C. Controls are available on the heater, through a remote or through Dreo’s app; the source also lists compatibility with Google Home and Alexa. The reported UK recommended retail price is £119.99.
Two Heating Modes, One Portable Unit
The 720S’s main selling point in the review is that it can serve different needs without requiring a separate personal heater and room heater. Focused airflow is intended for someone sitting nearby, while the raised, all-direction outlet is designed to spread heat across a room. That flexibility may be useful in homes where people move between a desk, living area and shared space.
The test results also show why room size and placement matter. The smaller living room warmed more quickly than the larger kitchen-diner, and Handley found that positioning the heater away from a wall helped with whole-room use. The figures are one reviewer’s measurements under her home’s conditions, not independently verified performance ratings or a promise that every room will heat at the same rate.
Electric heaters can add to household energy use, so the range of settings and Eco mode may be relevant to buyers comparing running costs. Ideal Home lists an estimated cost of 53 pence per hour, based on the October 2026 energy price cap. Actual costs depend on electricity prices and how the heater is operated; the article does not provide a measured cost from the 10-day test.

How the 720S Was Tested
Ideal Home describes the 720S as a ceramic fan heater launched at the end of September. The review says Handley tested it in the living room and kitchen-diner of her 1970s three-bedroom home for 10 days. The source does not specify the year of the launch, so a more precise product timeline cannot be established from the report.
The heater measures 22 by 30 by 22 centimetres, according to the published specifications, and has a handle for carrying. The review reports no assembly beyond putting batteries in the remote. Its listed safety features include tip-over protection, a child lock, cool-touch housing and overheat protection. The source also describes colour-adjustable ambient lighting controlled through the app.
Handley’s report is a product test, not a controlled comparison with other heaters. The published temperature changes reflect two rooms in one home; the article does not give details such as outdoor temperature, insulation performance or the measurement equipment used. Those limits matter when interpreting the results for a different property.
“I loved this switch, and I even did a bit of a giddy giggle when I tried it for the first time.”
— Sarah Handley, Ideal Home reviewer
What the Test Cannot Establish
The review does not establish how the heater would perform across different building types, insulation levels, room layouts or colder weather. Its temperature readings come from two rooms in one home, and the source does not describe a controlled comparison or independent laboratory test. Readers should treat the measured warming times as a single reviewer’s experience.
The source lists a running-cost estimate of 53 pence per hour using the October 2026 energy price cap, but does not provide the calculation details or a measured bill impact. Costs can change with electricity tariffs and use. The report also does not specify the product’s launch year, nor does it say how long the heater can sustain a target temperature or how its app functions performed over a longer period.
Further Tests and Buyer Checks
The source contains no announced follow-up test or new product milestone. Anyone considering the 720S can compare its listed £119.99 recommended price, power settings, room-size guidance and app features with current retailer information, as prices and availability may change. They can also check whether the dimensions and power-cord placement suit the intended room.
For practical use, the reviewer’s experience suggests considering both the size of the space and the position of the wall socket. The heater should be placed where its airflow is not obstructed, with the cable managed to reduce trip risk. The source lists safety functions, but does not replace the manufacturer’s operating instructions; buyers should follow those instructions and keep the appliance away from materials or locations the manual identifies as unsafe.
Key Questions
Can the Dreo 720S heat one person or a whole room?
According to Ideal Home’s review, it offers focused airflow through the front grille and a separate mode that distributes heat in 360 degrees. The reviewer tested both modes, but room-wide performance will vary with room size and conditions.
How quickly did it warm the rooms in the review?
Handley reported a 4°C increase in 10 minutes in an 18-square-metre living room. In a 22-square-metre kitchen-diner, she recorded a 2°C increase in 20 minutes. These were measurements in her home, not guaranteed results.
What controls and settings does the heater have?
The 720S has three power levels—1,100W, 1,400W and 2,000W—plus Eco and fan-only modes. The report says it can be controlled using the unit’s panel, a remote or Dreo’s app, and lists Google Home and Alexa compatibility.
What price and running cost does the review list?
Ideal Home lists a £119.99 recommended retail price and an estimated running cost of 53 pence per hour based on the October 2026 energy price cap. The actual cost depends on the user’s tariff and operation, and the review does not report a measured cost from testing.
