Best electric heaters UK (2026): oil-filled, convector, fan and panel

A plug-in electric heater is the fallback most British homes reach for when the boiler stops, one room is colder than the rest, or someone who feels the cold needs more warmth than the central heating gives.

Our verdict
Our verdictResearched

Dimplex describes this as a Thermocore column radiator with no oil to leak or top up, a frost setting and a 24-hour programmable timer with an LCD screen and up to four on/off programmes, per its manual. It sits at the simpler end of the radiator group on this page: no app and no remote, with rotary dials for heat and temperature. Compared with the same maker's ECR20 it adds the timer, which is the main reason to choose it. Dimplex's manual says it suits well-insulated spaces or occasional use, so treat it as a room heater, not whole-house heating.

Best for A bedroom or small living room that needs steady, quiet-running background heat with a built-in daily timer.

Good
  • Dimplex states it has an electronic 24-hour timer, three heat settings and a frost setting
  • Oil-free column design with castors, and a 1.8m cable per the maker
  • Safety cut-out on Dimplex's page, and a tilt switch in its manual
Worth knowing
  • The timer's backup battery needs about 72 hours plugged in to charge before it will hold the time through a power cut, per Dimplex's manual
  • About 10kg, heavier than the convectors here

Who shouldn't buy it: You want app or voice control, or a lighter heater to move daily: look at the Devola glass panel or a convector instead.

De'Longhi Radia S
Oil-filled radiator, 9 fins · 2,000 W · Digital panel, 3 settings, electronic timer · Safety thermostat, child lock; no tip-over listed

A bedroom or lounge up to about 60 cubic metres where you want a digital thermostat and a timer.

Our verdict
Our verdictResearched

De'Longhi's UK page lists the Radia S as 2000W maximum and 900W minimum with three power settings, a digital panel, an electronic timer and a two-year warranty. As an oil-filled radiator it heats slowly and keeps releasing warmth after switch-off, which suits steady use better than quick top-ups. Its digital controls set it apart from the dial-only Dimplex column radiators. It is a branded, established choice with UK support, though not the cheapest.

Best for A bedroom or lounge up to about 60 cubic metres where you want a digital thermostat and a timer.

Good
  • De'Longhi lists a digital control panel with temperature, power and timer setting
  • Two-year warranty included, per De'Longhi's UK page
  • Rated for rooms up to 60 cubic metres
Worth knowing
  • Slow to warm a cold room compared with a fan heater
  • About 12kg

Who shouldn't buy it: You need heat within minutes of switching on: a fan heater responds faster, though it cools just as quickly.

Herschel Select XLS400W
Infrared panel, wall or ceiling · 400 W · None built in; pairs with Herschel thermostat · IP44 per Herschel; front runs at 95-105C

A small bedroom or study where a plug-in wall or ceiling panel suits better than a hard-wired one.

Our verdict
Our verdictResearched

The Select XLS is Herschel's plug-in panel line: the maker lists a fitted UK plug and a 1.8m cable, with wall or ceiling mounting, or freestanding on optional feet. Herschel says it pairs with its wireless thermostats and offers app and voice control; the Amazon listing notes no thermostat is included. Herschel gives a front temperature of 95 to 105 degrees, so keep furniture and curtains clear. Like any electric heater, it turns each watt into a watt of heat, and 400W suits a small room.

Best for A small bedroom or study where a plug-in wall or ceiling panel suits better than a hard-wired one.

Good
  • Fitted plug, so no hard wiring, per Herschel
  • Wall, ceiling or freestanding with optional feet
  • Herschel lists TUV GS approval and a five-year warranty
Worth knowing
  • No thermostat included, so temperature control means buying one
  • Front reaches 95 to 105C per Herschel, so it is hot to touch
  • Needs secure fixings into a suitable wall or ceiling

Who shouldn't buy it: You want one heater with a built-in thermostat and display: look at a freestanding model with integrated controls.

Devola DVPW1500WH
Glass panel heater · 1,500 W · Wi-Fi app, remote, timer, thermostat · Child lock, frost mode, open-window detection

A living room or home office where you want scheduled, app-controlled heat without a bulky unit.

Our verdictResearched

Devola says this 1.5kW glass panel suits rooms up to 20 square metres, mounts on a wall or stands on the supplied feet, and works with Alexa, Google and the Tuya app. It is the smart-control pick on this page, with a timer, child lock, frost mode and open-window detection listed. Panel heaters warm gradually and radiate as well as convect. At 7.5kg it is heavier than a convector, and a wall-mounted panel should be fixed as the instructions say.

Best for A living room or home office where you want scheduled, app-controlled heat without a bulky unit.

Good
  • Wi-Fi, a timer, a remote and an eco mode at half output are all listed
  • Child lock, frost mode and open-window detection
  • Two-year warranty on registration, per the maker
Worth knowing
  • Heavier and less portable than a convector, so best left in one room
  • Smart features depend on a Wi-Fi connection and the Tuya app

Who shouldn't buy it: You want something to carry between rooms or do not use apps: a convector or radiator is simpler.

Herschel Comfort HC-420
Infrared panel, wall or ceiling · 420 W · None built in; Herschel controls sold apart · IP44 per Herschel; no plug, needs wiring in

A bedroom or home office of modest size that wants quiet background warmth.

Our verdict
Our verdictResearched

Herschel makes the Comfort range in the UK and classes it as a fixed low-temperature infrared heater: like other radiant panels, it warms people and surfaces in front of it rather than mainly heating the air. The HC-420 is the 420W size, 60x60cm per the Amazon listing, for wall or ceiling fixing. Herschel gives a surface temperature of 95 to 110 degrees, a five-minute warm-up and a ten-year warranty. Every watt of electric heat is a watt of heat whatever the heater type, so the case for a panel is comfort and placement, not a lower bill.

Best for A bedroom or home office of modest size that wants quiet background warmth.

Good
  • Square 60x60cm panel that fits most wall spaces
  • Ten-year warranty and UK manufacture, per Herschel
  • No fan, so it runs silently
Worth knowing
  • No built-in controls: Herschel says it meets Lot 20 only with its own controls
  • Supplied with 1.8m of cable and no plug, so an electrician has to wire it in

Who shouldn't buy it: You want a heater you can plug in and control straight from the box: this one needs wiring in and a separate controller.

Herschel Comfort HC-600
Infrared panel, wall or ceiling · 600 W · None built in; Herschel controls sold apart · IP44 per Herschel; no plug, needs wiring in

A medium bedroom or living area where the wall space allows an 800mm panel.

Herschel makes the Comfort range in the UK and classes it as a fixed low-temperature infrared heater: like other radiant panels, it warms people and surfaces in front of it rather than mainly heating the air. The HC-600 is the 600W size, 60x80cm per the Amazon listing, for wall or ceiling fixing. Herschel gives a surface temperature of 95 to 110 degrees, a five-minute warm-up and a ten-year warranty. Every watt of electric heat is a watt of heat whatever the heater type, so the case for a panel is comfort and placement, not a lower bill.

Best for A medium bedroom or living area where the wall space allows an 800mm panel.

Good
  • Mid-range output from a 60x80cm panel
  • Ten-year warranty and UK manufacture, per Herschel
  • No fan, so it runs silently
Worth knowing
  • No built-in controls: Herschel says it meets Lot 20 only with its own controls
  • Supplied with 1.8m of cable and no plug, so an electrician has to wire it in

Who shouldn't buy it: You rent, or cannot fix a heavy panel to the wall or ceiling and have it wired in.

Dimplex ECR20
Oil-free column radiator · 2,000 W · Mechanical dial, 3 heat settings · Safety cut-out and tilt switch

A medium room where you want simple dial controls and no timer to program.

Our verdict
Our verdictResearched

The ECR20 is the no-timer version of the Dimplex column radiator above, with a mechanical dial and three heat settings according to Dimplex. It is the lighter-on-features choice from a maker with UK support. Pick it if you will switch it on and off by hand and do not need scheduling. If you want the timer, the ECR20Tie is the same body with one added.

Best for A medium room where you want simple dial controls and no timer to program.

Good
  • Dimplex lists 2kW, three heat settings and a mechanical dial
  • Oil-free design with castors; 1.8m cable per the maker
  • Overheat cut-out and tilt switch, per Air Concentre's listing
Worth knowing
  • No timer, so it only runs when you switch it on
  • About 10kg per Air Concentre, so heavier to carry than the convectors here

Who shouldn't buy it: You want it to start on a schedule: choose the ECR20Tie or a convector with a 7-day timer.

Dimplex Eco Chico
Compact oil-free radiator · 700 W · Rotary thermostat, 1 heat setting · Safety cut-out and tilt switch; frost setting

A small bedroom, box room or office where low, steady warmth matters more than speed.

Our verdict
Our verdictResearched

Dimplex describes the Eco Chico as a compact 700W oil-free radiator with a rotary thermostat and a frost setting. At 700W it draws far less than the 2kW heaters on this page, so it is gentle on the meter but will not lift a large room quickly. Dimplex gives it a three-year guarantee on its page, longer than several rivals. Think of it as a small-space or draught-chasing heater.

Best for A small bedroom, box room or office where low, steady warmth matters more than speed.

Good
  • Dimplex states 700W with a thermostat and frost setting, so a low draw
  • Safety cut-out and tilt switch both listed by the maker
  • Small and portable: 448mm high with a 1.3m cable
Worth knowing
  • Only one heat setting and 700W, so it is slow to warm anything beyond a small room
  • Limited controls: no timer

Who shouldn't buy it: You need to heat a lounge or a cold extension: a 2kW radiator or convector fits better.

Dimplex HeatLite 2kW
Convector · 2,000 W · Dial thermostat, 3 heat settings · Safety cut-out and tilt switch

Quick top-up heat in a bedroom, study or hallway up to about 20 square metres, without programming anything.

Our verdict
Our verdictResearched

Dimplex rates the HeatLite for rooms up to 20 square metres and lists three heat settings with a thermostat dial. It is a plain, light convector from a mainstream maker, the sort of heater you plug in and forget the controls on. It is the simplest heater in the convector group here, with no app and nothing to programme. Convectors warm the air rather than you, so they suit a room you will be in for a while.

Best for Quick top-up heat in a bedroom, study or hallway up to about 20 square metres, without programming anything.

Good
  • Dimplex lists 2kW, 3 heat settings and an adjustable thermostat
  • Tilt switch and safety cut-out listed on the maker's page
  • Carry handles and plug-in use, with no installation needed
Worth knowing
  • No app control, and Dimplex describes dial controls only; its spec table also lists a digital timer, so check before relying on one
  • Warms the air, so it feels slower than a fan heater when you walk into a cold room

Who shouldn't buy it: You want scheduled heating or a heater for brief, fast bursts: a timer convector or ceramic fan heater suits better.

De'Longhi Capsule You&Me

Our verdictResearched

De'Longhi's UK page lists the Capsule You&Me as a 2000W ceramic fan heater with 1000W as the lower setting, oscillation, a digital panel with remote, a timer and a tip-over switch. It is the most feature-rich fan heater here and compact at 1.3kg. Fan heaters respond fast but cool quickly, so it suits short spells in an occupied room. De'Longhi's page gave it a two-year warranty, and noise is listed at 45 to 48dB.

Best for A small room where you want quick, evenly spread warmth you can set with a remote and timer.

Good
  • De'Longhi lists oscillation, a remote and a digital timer
  • Tip-over switch listed; 2-year warranty on De'Longhi's UK page
  • Compact and light at 1.3kg
Worth knowing
  • Only two power settings: 1000W and 2000W
  • Stated noise of 45 to 48dB is audible in a quiet bedroom

Who shouldn't buy it: You want quiet, constant background heat: a radiator or panel heater suits better.

Herschel Comfort HC-215

Herschel makes the Comfort range in the UK and classes it as a fixed low-temperature infrared heater: like other radiant panels, it warms people and surfaces in front of it rather than mainly heating the air. The HC-215 is the 215W size, 60x30cm per the Amazon listing, for wall or ceiling fixing. Herschel gives a surface temperature of 95 to 110 degrees, a five-minute warm-up and a ten-year warranty. Every watt of electric heat is a watt of heat whatever the heater type, so the case for a panel is comfort and placement, not a lower bill.

Best for A small room, hallway or desk alcove where a low-output panel on the wall is enough.

Good
  • Smallest Comfort size, about 4kg according to The Eco Experts, so the lightest to fix
  • Ten-year warranty and UK manufacture, per Herschel
  • No fan, so it runs silently
Worth knowing
  • Only 215W, so it suits a very small or well-insulated space
  • Supplied with 1.8m of cable and no plug, so an electrician has to wire it in

Who shouldn't buy it: You want a plug-in heater you can move between rooms: this is fixed and wired in.

Herschel Comfort HC-850

Dimplex DXUC2BS

Our verdict
Our verdictResearched

Dimplex describes the DXUC2BS as a 2kW upright ceramic fan heater with three power settings, warm or cool air and an adjustable thermostat. Fan heaters respond faster than the radiators and convectors here but cool down just as quickly and are noisier. It is the small, inexpensive end of a Dimplex-brand choice. Use it for short top-ups and keep it clear of curtains and fabric.

Best for Fast warmth at a desk, on a landing or in another small space you only use for a short time.

Good
  • Dimplex lists 2kW, three settings and a cool-air mode for summer use
  • Adjustable thermostat and frost setting
  • Tilt switch and carry handle listed
Worth knowing
  • Fan noise, and heat stops soon after it is switched off
  • Not suited to running for hours in a large room

Who shouldn't buy it: You want quiet background heat for an evening or overnight: choose an oil-filled or oil-free radiator.

Dimplex 3kW Flat Fan
Fan heater (flat) · 3,000 W · Thermostat dial, 2 heat settings, cool-air mode · Safety cut-out and tilt switch; frost setting

Our verdict
Our verdictResearched

At 3kW this Dimplex draws about as much as a 13A plug is designed to carry, so it heats a large space faster than the 2kW models here, with two heat settings, a thermostat with frost setting and a cool-air option per the maker. That also means it must go straight into a wall socket, never an extension lead or adaptor, and it should not be left running unattended. Dimplex gives it a three-year guarantee on its page. For ordinary rooms a 2kW heater is the more measured choice.

Best for A big heat boost in a larger room or conservatory when you are in the room and can watch it.

Good
  • Dimplex states 3kW with two settings and a thermostat for large rooms
  • Safety cut-out and tilt switch listed
  • Slim and light at 1.3kg per the maker
Worth knowing
  • High draw: at full output it uses half as much again as the 2kW heaters here
  • Fan noise, and no timer

Who shouldn't buy it: The room is small or you want something to leave running: a 2kW radiator or a lower-power heater is safer and cheaper.

De'Longhi lists the Capsule Hobby HFS30C24.DG with IP21 drip protection and a two-year warranty, and a UK retailer lists 1500W and 2400W settings, an adjustable thermostat, a two-position stand, a tip-over switch and a thermal fuse. That retailer puts it at about 45dB on higher settings, a noticeable hum. It heats a small room quickly but still suits short use. At 2.4kW it should go straight into a wall socket, never an extension lead, and must not be covered.

Best for A compact, higher-output fan heater for a workroom, hobby room or other small space used in short spells.

Every watt of electric heat is a watt of heat whatever the heater type, so the case for a panel is comfort and placement, not a lower bill.

Igenix lists the IG5200 as a 2kW convector at 2.0kg with three heat settings, an adjustable thermostat and carry handles, and offers a two-year guarantee when you register. It is a plain no-frills heater, closest in kind to the Dimplex HeatLite. The Igenix listing names overheat protection but does not mention a tip-over switch, which is worth knowing if a heater may be nudged by children or pets. The lower 750W and 1250W settings let you avoid running at full draw.

Our verdictResearched

Dimplex lists the DXFF20TSN as a 2kW flat fan heater with two heat settings, an adjustable thermostat with a frost setting, and a cool-blow mode for summer. It stands about 11cm high, so it sits low on the floor. Like any fan heater it warms the air fast and stops warming soon after it is switched off, so it suits short bursts rather than all-evening heat. Plug it straight into a wall socket rather than an extension lead, and never cover it or let fabric near the grille.

De'Longhi's UK support page names the Dragon 4 TRD41025T as a 2.5kW oil-filled radiator with a mechanical timer; Air Concentre gives 1100W, 1400W and 2500W settings, a 24-hour timer set by knobs and a 75 cubic metre room rating. It is the highest-output radiator on this page, so it draws the most per hour. Air Concentre says registering with De'Longhi extends the warranty to 10 years. Neither source names its safety features, so it scores below the radiators whose makers list them.

Pro Breeze lists this 2000W mini ceramic fan heater at 1.44kg with three power modes plus fan-only, a thermostat, overheat protection and an anti-tip switch, for rooms up to 15 square metres. It is less established than Dimplex or De'Longhi, though Pro Breeze is a recognisable UK-sold brand. Noise is stated as 55dB, so it is audible. It is a short-spell heater, not a radiator replacement.

Dimplex describes the Desk Friend as a compact 400W ceramic fan heater for desks and bedside tables, with two heat settings, two fan speeds, an adjustable thermostat and a detachable handwarmer. At 400W it uses a fifth of the power of a 2kW heater, but Dimplex itself says it is for personal warmth rather than a whole room. Keep it on a clear, stable surface and plugged into a wall socket.

Best for Warming one person at a desk or bedside when heating a whole room would be wasteful.

Good
  • Dimplex lists 400W, so an hour at full power uses 0.4kWh
  • Two heat settings, two fan speeds and an adjustable thermostat
  • Tilt switch listed, plus a detachable handwarmer
Worth knowing
  • Warms one person close by, not a room
  • Dimplex's spec sheet lists a tilt switch but no separate overheat cut-out

Who shouldn't buy it: You need to bring a whole cold room up to temperature.

The honest bit
Direct electric heating is one of the dearest ways to heat most UK homes, because a unit of electricity costs several times a unit of gas. It earns its place when you only need one room warm, or when the boiler has failed. If your central heating works, closing doors, draught-proofing and a heated throw or electric blanket will usually do more for less: an electric blanket draws a fraction of what a 2kW heater does. A plug-in heater also needs mains power, so it is no help in a power cut; see our keeping-warm-in-a-power-cut page. Never bring a fuel-burning heater indoors in its place.

Before you buy

Start with the type, because it decides how the room feels.

Oil-filled radiators, and the oil-free column radiators Dimplex sells as an alternative, warm slowly and keep giving out heat after they switch off, so they suit a long evening in one room or warming a bedroom on a timer before bed. Convectors heat the air quickly, are light enough to carry between rooms, and cool as soon as they stop. Fan heaters are the fastest to feel and the noisiest, best for a short burst on a landing or in a home office. Never use a portable heater in a bathroom. Panel heaters are slim, often wall-mountable, and gradual.

Most heaters here are 2kW, with a 700W compact radiator, a 1.5kW panel and 2.5kW and 3kW models either side.

3kW is the most a 13A plug is designed to carry, so the 3kW fan heater runs at that limit. At full output a 2kW heater uses two units of electricity an hour; multiply by the unit rate on your bill for the hourly cost, and a thermostat cycles it off once the room is warm, so real use is lower. Lower settings matter more than the headline figure: the low settings here, from 600W to about 1,000W on several models, hold a warm room without full draw.

Read the safety list on the maker's page, not the retailer's.

The features worth having are a thermal cut-out that stops the heater overheating, a tilt or tip-over switch that cuts power if it is knocked over, and a frost setting that holds a room just above freezing. About half the heaters on this page have both of the first two stated by the maker or a UK retailer; where a listing names only one, or none at all, our product entry says so. Some newer models, such as the Devola panel, also add open-window detection, which reduces heat when it senses a sudden drop in temperature.

Follow the fire-service rules every time, whichever heater you buy.

Plug it straight into a wall socket, never an extension lead or adaptor: a heater running near a lead's rated limit for hours can overheat it, and Dimplex's ECR20Tie manual gives the same warning. Keep it at least a metre from curtains, bedding and furniture, never dry clothes on it, and switch it off when you go to bed or leave the room. Check the plug and cable for damage each autumn, register the product so you hear about recalls, and check GOV.UK's product recalls list if you bought second-hand.

Then choose controls to match how you will use it.

A mechanical dial is the simplest to live with. A 24-hour timer can warm a room before you wake or before bed, though Dimplex's ECR20Tie manual says its timer's backup battery needs about three days plugged in before it holds the time through a power cut. App control, on the Devola panel here, suits heating on a schedule but depends on Wi-Fi and the maker's app. If the heater will travel, check weight: the fan heaters here are about 1.3 to 1.5kg, the Igenix convector 2kg, the panel 7.5kg and the full-size radiators about 9 to 12kg.

How we choose

We verify every product's specifications against at least two independent sources, re-check its UK price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labelled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test — and commissions never change a ranking either way.

Common questions

Which type of electric heater is cheapest to run?

They all turn electricity into heat at the same rate, so a 2kW heater of any type costs the same per hour at full output. What changes the bill is how long it runs. A heater with a working thermostat cycles off once the room reaches temperature, and a lower setting of 600W to about 1,000W holds a warm room for a fraction of full draw. Oil-filled radiators feel cheaper because they keep radiating after switching off; fan heaters feel dearer because they cool instantly.

Oil-filled or oil-free radiator: what is the difference?

An oil-filled radiator heats a sealed reservoir of oil that stores warmth and releases it gradually, so it stays warm after the element stops. An oil-free column radiator, such as Dimplex's Thermocore models, uses a dry heating element in the same shape, so there is nothing to leak, it is lighter and it warms up faster, but it cools sooner. Both are quiet and suit long spells in one room. Neither is better in a bedroom on a thermostat; the choice is weight and warm-up time.

Is it safe to leave an electric heater on overnight?

Fire services advise against leaving portable heaters running unattended or while you sleep, so switch it off when you go to bed. To take the chill off a bedroom, run a radiator or panel heater with a thermostat, cut-out and tip-over switch before bed, a metre from bedding and curtains, or set its timer to end before you sleep. Electrical Safety First also advises against drying clothes on heaters. For someone who feels the cold, an electric blanket with an all-night setting, used as its instructions say and replaced at about ten years old, is a safer option.

Can I plug an electric heater into an extension lead?

No. Fire services and Electrical Safety First say heaters should go straight into a wall socket. A 2kW heater draws close to 9 amps and a 3kW model about 13, which is the limit of a standard UK plug; running near a lead's or adaptor's limit for hours, especially with other things plugged in, can make it overheat. Dimplex's ECR20Tie manual repeats the warning. If the socket is in the wrong place, move the heater, not the lead.

What size electric heater do I need for my room?

Makers rate heaters by room size: Dimplex and Devola quote around 20 square metres for their 2kW convector and 1.5kW panel. De'Longhi quotes 60 cubic metres for its 2kW Radia S, and a UK retailer lists 75 for the 2.5kW Dragon 4, roughly a 25 to 30 square metre room with ordinary ceilings. A 700W heater suits a box room or a draughty corner. In a poorly insulated or high-ceilinged room, a heater will take longer, run more, and may not keep it warm on its own.

Will an electric heater work in a power cut?

No. Every heater here needs mains electricity. A 2kW heater would drain a typical 1kWh portable power station in about half an hour, and even large units in an hour or two, so battery backup is not a realistic way to run one. In a cut, the safe route is layers, warm drinks, one room with the door shut, and blankets or a sleeping bag. Never use a gas or paraffin heater, camping stove or barbecue indoors: they give off carbon monoxide, which can be fatal. Our keeping-warm-in-a-power-cut page covers what helps.
