Ideal Home’s 10-day review found that Dreo’s 2,000W Smart Whole Room Heater 720S can switch between directed heat and 360-degree airflow. In tests, it raised an 18-square-meter living room’s temperature by 4°C in 10 minutes; a 22-square-meter kitchen-diner warmed by 2°C in 20 minutes.
Dreo’s Smart Whole Room Heater 720S can direct warmth toward one person or use 360-degree airflow to heat a room, according to a hands-on review by Ideal Home. The publication tested the 2,000W ceramic fan heater for 10 days and reported that it raised the temperature in an 18-square-meter living room by 4°C in 10 minutes, while taking longer to warm a larger open-plan kitchen-diner.
The heater switches between focused heating from its front grille and whole-room mode, in which its upper section rises by about 4 centimeters and distributes air in all directions. Ideal Home reviewer Sarah Handley said the mode change was simple to operate. The heater has three power settings—1,100W, 1,400W and 2,000W—as well as an Eco mode that adjusts output toward a selected temperature and a fan-only setting.
In the reviewer’s home, the living room measured 18 square meters. Its temperature rose by 4°C over 10 minutes in whole-room mode. In a 22-square-meter kitchen-diner, the temperature rose by 2°C in 20 minutes. These are results from one home test, not a guarantee of performance in other rooms; the review does not specify all conditions, such as starting temperature or insulation. Handley said she moved the heater farther into the room for the whole-room test, while noting that its power cord limits where it can be placed.
The 720S measures 22 by 30 by 22 centimeters and weighs 3.1 kilograms, according to the review. It can be controlled using its onboard panel, remote or Dreo app, and works with Google Home and Alexa. The listed retail price is £119.99. Ideal Home estimated running costs at 53p per hour using the October 2026 energy price cap; actual costs depend on the electricity tariff and how the heater is used.
Two Heating Patterns From One Unit
The 720S is designed to address two common uses for a portable heater: warming a person who is sitting nearby and spreading heat more broadly around a room. Switching between directed warmth and room-wide airflow means buyers may not need to choose one type of heater for those separate situations. The review’s test results also show why room size and placement matter: the larger kitchen-diner warmed more slowly than the living room.
For households comparing portable electric heaters, the advertised wattage is only part of the practical picture. The reviewer’s results offer an example of performance in two specific spaces, while the stated 53p hourly running-cost estimate gives a reference point tied to a particular energy-price calculation. It is not a fixed cost for every household, and frequent use at the highest setting could make electricity consumption a key factor in deciding whether the convenience is worthwhile.

How Ideal Home Tested the 720S
Ideal Home says the 720S launched at the end of September. Handley, the publication’s Renovation Editor and Home Energy lead, tested it in the living room and kitchen-diner of her 1970s, three-bedroom home for 10 days. That scope matters: the reported temperature changes come from a single home and two rooms, rather than a controlled comparison across multiple properties.
The review identifies the product as a ceramic fan heater rated at 2,000W, with suitability listed for rooms up to 25 square meters. It also notes that the unit has no oscillation. Instead, its whole-room function uses the raised top section to send heat in all directions. The unit has several stated safety features, including tip-over protection, a child lock, cool-touch housing and overheat protection; the review’s description does not independently verify each feature through testing.
““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
Performance Depends on Room Conditions
The review reports results from one home but does not provide a controlled comparison with other heaters or enough detail to establish how the unit would perform across different building types, starting temperatures or insulation levels. The listed suitability of up to 25 square meters is a product specification, not proof that every room of that size will warm at the same rate.
The 53p hourly figure is an estimate based on the October 2026 energy price cap, not a universal tariff. The total cost will vary with a household’s electricity rate, selected power setting and use pattern. The review also does not establish whether the app’s smart-home functions or the stated safety features were independently tested beyond normal use.
Check Price and Local Running Costs
The next practical step for prospective buyers is to check the current price and compare the heater’s power use with their own electricity tariff. Dreo lists the unit’s controls, app compatibility and safety features, while retailers may have different prices or availability. No later test or product update is described in the source material.
Readers weighing the 720S against other heaters can use Ideal Home’s figures as a single-home test reference, not a promise of results. Placement, room layout and access to a safe wall socket are relevant to use: the reviewer found the cord restricted how centrally the unit could be positioned and advised being mindful of the trailing cable.
Key Questions
Can the Dreo 720S heat a whole room or just one area?
It has two airflow modes. Focused mode sends heat from the front grille toward a person or area, while whole-room mode raises the upper section and distributes air in 360 degrees.
How quickly did it warm the rooms in the review?
Ideal Home recorded a 4°C rise in 10 minutes in an 18-square-meter living room and a 2°C rise in 20 minutes in a 22-square-meter kitchen-diner. Those results reflect one home test and may not match other rooms.
What does the Dreo 720S cost to run?
Ideal Home estimated 53p per hour, based on the October 2026 energy price cap. A household’s actual cost depends on its electricity tariff and the heater’s setting and usage.
How can the heater be controlled?
The 720S has an onboard control panel and remote, and it can be operated through the Dreo app. The review says it also works with Google Home and Alexa.
What safety features does the review list?
The review lists tip-over protection, a child lock, cool-touch housing and overheat protection, among eight safety features. These are product features reported by Ideal Home; the source does not describe independent certification tests.
