Cold room, rising bills, and no time to wait? The right electric heater depends less on the brand and more on the type: fan heater, convector or oil-filled radiator. We've analysed expert tests and real owner reviews to find the best for every room. Start with these 10 buying factors.
Top 10 Buying Factors
- Heater type — fan heaters warm in seconds; convectors heat steadily over hours; oil-filled radiators keep radiating after switch-off
- Room size — check the rated area: up to 15 square metres suits a bedroom; 25 square metres or more needs 2,000 watts or more
- Wattage — 1,500 watts handles small rooms; 2,000-2,500 watts suits living rooms; higher wattage uses more electricity per hour
- Thermostat — holds your chosen temperature instead of heating nonstop; look for adjustable, accurate control
- Timer — a 24-hour timer warms rooms before you wake; a 7-day timer suits a weekly routine
- Noise — under 40 decibels is bedroom-quiet; convectors and oil radiators with no fan run near-silently
- Oscillation — side-to-side movement spreads warmth across a room; without it, heat goes one way
- Safety — tip-over and overheat cut-outs are essential around children, pets and bedding
- Weight and portability — under 3 kilograms carries easily; oil radiators of 12 kilograms or more need castors
- Smart control — app and voice control let you schedule heat remotely; check whether 2.4 gigahertz Wi-Fi is required

Small enough for a bedside table, quiet enough to leave running while you work.
- Room size: designed for rooms up to 15 square metres — right for a bedroom or home office, not a living room
- Weight and portability: around 1.4 kilograms, light enough to move from desk to bedside
- Thermostat: an eco mode lets you set a target temperature, then switches to fan-only once it's reached
- Oscillation: none, so heat goes in one direction — aim it at where you sit
Ideal Home tested it for two weeks in a bedroom and home office and found it quiet and quick to heat up
Ideal Home called it one of its favourite heaters it has ever tested
Ideal Home felt the design isn't as stylish as retro-style rivals — worth knowing if it sits on show
Not built for larger rooms; Morphy Richards' 2,000 watt tower is the better fit there
Home workers and light sleepers heating one small room. Ideal Home tested it in exactly that setting — a bedroom and home office — and rated it among its favourites.

The Russell Hobbs turns from side to side, spreading warm air across a bedroom rather than blasting one spot.

- Timer: a 24-hour timer and remote, so the room is warm before you get up
- Noise: Russell Hobbs describes it as silent — the brand's claim, not a measured figure
It averages 4.4 stars across more than 500 owner ratings, and buyers describe it as very quiet
One owner said the thermostat holds within a couple of degrees
We couldn't find independent tests, so the evidence comes from owners
Like all fan heaters, the warmth stops the moment it switches off
Bedrooms, and anyone who wants the room warm before they get up. Owners describe it as very quiet, and one found the thermostat holds within a couple of degrees.

It is Quiet Mark certified, T3 noted
Ideal Home found it isn't the quietest it tested, and retailers list it at 46 decibels — louder than bedroom-quiet
There's no built-in timer, so it won't switch on before you get home without the app
Households with an open-plan kitchen-diner where a one-direction heater leaves cold corners. Ideal Home named it their best for large rooms.

It replaces the AM09, so older AM09 reviews don't apply to this model

No fan, no noise: a 2 kilowatt convector with three heat settings and an adjustable thermostat.

- Wattage: 2 kilowatts — best for steady background heat over a few hours in a living room or study
- Noise: no fan, so it runs silently
- Timer: none on the manual version; Dimplex also makes HeatLite models with Wi-Fi, a timer or a turbo fan
Early owners rate it close to 5 stars, though from few reviews so far
It comes from a trusted British heating brand
It's a new model with limited reviews and no independent tests yet
The manual version has no timer, so it won't switch itself on before you get home
Anyone who wants quiet background heat from a trusted heating brand without paying for smart features. Early owners rate it close to 5 stars.
If you want convector-style heat on the wall, controlled from your phone, the Devola mounts flat.

Radiator-style warmth without the oil — lighter and quicker to heat than an oil-filled model.
- Heater type: oil-free radiator — steady, radiator-style heat that warms up faster than oil-filled models
- Room size: rated for rooms up to 60 cubic metres, roughly a 24 square metre living room
- Wattage: 2,000 watts — the living-room benchmark from the buying factors
- Weight and portability: no oil inside, so it's lighter than oil-filled radiators of the same output
Dimplex is one of the UK's longest-established heating brands, and the Eco Edge is a new addition to its oil-free range
Oil-free design means no risk of oil leaks over the radiator's life
It's a new model, so we couldn't find independent tests or many owner reviews yet
Without oil, it won't hold heat after switch-off as long as a true oil-filled radiator
Living rooms that need radiator-style warmth without the weight of oil. This is the second Dimplex here: the HeatLite is a basic fan-free convector, while the Eco Edge is a portable oil-free radiator.

An oil-filled radiator that keeps radiating heat after it's off — this is where heater type matters more than brand.
- Heater type: sealed oil inside 8 fins holds the heat; slowest to warm up, but stays warm after switch-off
- Wattage: runs at 900, 1,100 or 2,000 watts; its chimney design warms up faster than a traditional oil radiator
- Room size: De'Longhi rates it for 60 cubic metres, roughly a 24 square metre room
- Timer: a 24-hour timer, thermostat and anti-frost setting
Mumsnet rated the Dragon 4 the top electric heater in its testing
Owners praise how quietly it runs through the night
At around 15 kilograms it's heavy to move, despite the castors
One owner found the timer fiddly, and it's slow to warm up — not for a quick blast before a shower
Bedrooms, nurseries and living rooms where silent, steady background heat matters more than an instant blast. Mumsnet rated it the top electric heater in its testing.
