Our Top Picks

8 Best Electric Panel Heaters

1. Devola WiFi Enabled Smart Electric Glass Panel Heater 2000W

This is the panel heater we’d put in most UK homes. The Devola 2000W has quietly become one of the best-reviewed glass panel heaters on Amazon, and with good reason. It heats a medium-sized room effectively, the glass front stays cool to the touch on the sides (only the element gets warm), and the WiFi connectivity via the Smart Life app is genuinely useful rather than gimmicky. You can set schedules, control it remotely, and get it integrated with Alexa or Google Home in a few minutes.

The open window detection is a nice touch. When it senses a sudden temperature drop — consistent with a window being opened — it pauses heating automatically, which can make a real difference to your energy bills over a winter. It’s Lot 20 compliant, meaning it meets the UK’s energy-related product regulations, so you know it’s been independently verified for efficiency.

Installation is straightforward. It comes with wall-mounting brackets, but it also sits on the included feet as a free-standing unit if you’d rather not drill. The white glass finish is clean and modern. At £119.99 it isn’t the cheapest panel heater on this list, but it’s the most capable, and with 1,297 reviews to back it up, the reliability is proven.

Features

• 2000W output — suitable for rooms up to 20m²
• WiFi enabled via Smart Life / Tuya app
• Amazon Alexa and Google Home compatible
• Open window detection with automatic pause
• 7-day programmable timer and adjustable thermostat
• Wall mounted or free standing with included feet
• Lot 20 compliant for energy efficiency
• White glass front panel

2. Duronic Electric Heater HV220 Oil Free Convection Heater 2000W

The HV220 sits at an interesting intersection: it’s not a glass panel heater, and it’s not an oil-filled radiator either. Duronic’s micathermic technology means it heats up almost instantly (like a fan heater) but radiates that heat silently and evenly (like a radiator). The result is a panel heater that feels more comfortable to sit near than a fan heater, without the slow warm-up time of oil.

At £69.99 with 561 reviews at 4.5 stars, it punches well above its price. It can be wall mounted or used freestanding, and at just 25mm deep it barely protrudes from the wall. There’s a manual thermostat dial and two heat settings (1000W and 2000W). It’s not smart — no WiFi, no app — but for a bedroom or home office where you want silent, efficient heat without fuss, it’s hard to beat.

The lack of a timer is the main limitation. You’re controlling it manually or via a plug-in timer, which isn’t ideal. But if you don’t need scheduling and just want a slim, quiet, genuinely effective panel heater for under £70, this is our mid-range pick.

Features

• 2000W micathermic output — heats up almost instantly
• Completely silent operation — no fan, no moving parts
• Wall mountable or freestanding (25mm depth)
• Manual thermostat dial and dual heat settings (1000W / 2000W)
• Overheat protection and tip-over cut-off
• 561 reviews at 4.5 stars

3. Devola Wifi Enabled Smart Electric Glass Panel Heater 1000W

If you want the same Devola smart features as the 2000W version but for a smaller room — or you’d simply rather run a lower-wattage heater to keep bills down — the 1000W variant is worth a look. It has the same WiFi connectivity, Alexa and Google Home integration, and open window detection. The 430 reviews at 4.4 stars suggest it’s just as reliable as the higher-wattage sibling.

For a small bedroom, home office, or single-person study up to around 10m², the 1000W output is more than adequate. Running it at full power costs approximately 24p per hour at current UK electricity rates — notably cheaper than a 2kW unit running continuously. With programmable scheduling, you can bring the temperature up before you arrive in the room and let it tick over at a lower setting throughout the day.

Features

• 1000W output — ideal for smaller rooms up to 10m²
• WiFi via Smart Life / Tuya app, Alexa and Google Home compatible
• Open window detection
• 7-day programmable timer and digital thermostat
• Wall mounted or freestanding
• Lot 20 compliant
• 430 reviews at 4.4 stars

4. Duronic Electric Heaters HV101 Oil Free Convection Heater 2500W

If you need to heat a large room — a kitchen-diner, an open-plan living area, or a conservatory — the HV101’s 2500W output puts it ahead of most panel heaters on this list. Duronic’s micathermic technology means you get that power silently, with no fan noise, and the panel heats up in seconds rather than minutes. It’s the same core technology as the HV220 but scaled up, and with 805 reviews at 4.4 stars it’s clearly doing something right.

Like the HV220, it’s wall mountable or freestanding, and the slim profile means it doesn’t dominate the room. There’s a manual thermostat and two heat settings. No timer, no smart features. For spaces where output is the priority and noise is not acceptable — think sleeping babies, people working from home on calls, or light sleepers — the combination of 2500W and silent operation is genuinely hard to find elsewhere at this price point.

Features

• 2500W micathermic output — one of the most powerful silent panel heaters available
• Completely silent — no fan, no moving parts
• Wall mounted or freestanding
• Manual thermostat and dual heat settings
• Overheat protection and tip-over safety cut-off
• 805 reviews at 4.4 stars

5. Mylek Glass Panel Heater WiFi Enabled 2000W

The most divisive pick on this list, in a good way. The Mylek WiFi Glass Panel Heater has the highest rating of anything here at 4.7 stars — but with only 55 reviews, that figure comes with a caveat. It’s a relatively new listing, so the sample size is still small. That said, 55 people agreeing it’s excellent is not nothing, and the specification for the price is genuinely strong.

At £89.99 for a 2000W WiFi-enabled glass panel heater, it undercuts the Devola 2000W by £30. It has app control, and it sits freestanding or wall-mounts cleanly. If you want smart glass panel heating but are put off by the Devola’s price, the Mylek is worth serious consideration — just be aware you’re buying into a shorter track record.

Features

• 2000W output
• WiFi enabled with smart app control
• Glass front panel — white finish
• Wall mounted or freestanding
• Programmable timer and thermostat
• 4.7 stars from 55 reviews

6. JSH WiFi Enabled Electric Glass Panel Heater 2000W

Another strong contender in the crowded smart glass panel space. The JSH 2000W WiFi heater comes with both app control and a physical remote, which is something neither the Devola nor Mylek includes — useful if you’d rather not reach for your phone every time you want to tweak the temperature. It’s priced at £99.99 and carries 4.5 stars from 53 reviews.

The remote is particularly appreciated in bedrooms and living rooms where you want to make quick adjustments without getting up. App scheduling works in the same way as other WiFi models on this list, and it’s compatible with Alexa. The review count is still relatively low, but the scores are consistent and the specification is competitive for the price.

Features

• 2000W output
• WiFi app control and included physical remote
• Alexa compatible
• Glass front panel
• Wall mounted or freestanding
• Programmable timer and thermostat
• 4.5 stars from 53 reviews

7. Devola DVNDM10 Eco Electric Panel Heater 1000W

This is a no-nonsense, non-smart panel heater from Devola that’s well worth considering if you don’t need WiFi or app control. The DVNDM10 is a traditional slim panel heater with an adjustable thermostat, 24-hour timer, and two heat settings. At £69.99 with 186 reviews at 4.4 stars, it’s a solid, reliable option for anyone who finds the idea of pairing a heater with their phone unnecessary.

It’s slim, wall-mountable, and the white finish blends into most rooms without drawing attention. The 1000W output makes it best suited to bedrooms and small offices rather than larger living areas. If your main priority is keeping a single room comfortable at a low price without the complexity of smart features, this covers the bases well.

Features

• 1000W output — suited to rooms up to 10m²
• Adjustable thermostat with 24-hour programmable timer
• Two heat settings
• Wall mounted or freestanding
• Slim, low-profile design
• 186 reviews at 4.4 stars

8. Glen 2150Tie7 Electric Convector Heater 500W

At £42.50 this is the cheapest pick on this list, but the Glen convector heater earns its place. A 500W output sounds modest, but for a small room, a hallway, or a bathroom (it’s splash-proof), it’s often all you need — and running it costs just 12p per hour at current UK electricity rates. With 444 reviews at 4.4 stars, it’s better-reviewed than several pricier options here.

The 7-day LCD programmable timer is a genuine highlight at this price point. You can set different schedules for different days, which most heaters at under £50 simply don’t offer. It wall mounts with included fixings or sits freestanding with feet. The skirting board-style form factor is slim and unobtrusive. It’s not going to heat a large room, but for what it is, it represents very good value.

Features

• 500W output — ideal for small rooms, hallways, or bathrooms
• 7-day LCD programmable timer
• Wall mounted or freestanding
• Slim skirting board-style profile
• Splash-proof rated
• 444 reviews at 4.4 stars

Electric Panel Heater Buying Guide

Key Takeaways

• Electric panel heaters are among the slimmest, most wall-friendly heating options available — many are only 25–40mm deep
• Glass panel heaters look sleek but generally cost more than micathermic or traditional convection models
• WiFi-enabled models with scheduling are significantly more energy-efficient in practice than basic on/off models
• Wattage guide: allow roughly 100W per square metre for a well-insulated room
• Silent operation (no fan) is a feature of micathermic and convection panel heaters — important for bedrooms and offices
• Lot 20 compliance is worth checking — it means the heater meets UK energy efficiency standards independently verified

What Is an Electric Panel Heater?

An electric panel heater is a flat, slim electric heater designed to be mounted on a wall or used freestanding. Unlike storage heaters that charge overnight on off-peak electricity, panel heaters run on demand — you turn them on, they heat up, you turn them off. They’re designed to replace or supplement traditional radiators, and they’re particularly popular in rooms where a central heating radiator would be impractical or where you want independent temperature control.

The “panel” in the name refers to the form factor: a thin, rectangular unit, typically between 20 and 60mm deep, that fits flat against the wall. Most models come with wall-mounting brackets and freestanding feet, so you can choose how to install them. They’re popular in rented properties, new builds, extensions, and rooms that get added to a house after the central heating is installed.

How Do Electric Panel Heaters Work?

The heating mechanism varies by type. Glass panel heaters use an infrared heating element behind the glass, which warms the glass surface and radiates heat outward. Micathermic panel heaters (such as the Duronic models on this list) use mica-coated elements that combine radiant and convection heating — they’re almost instantaneous and completely silent. Traditional convection panel heaters draw cool air in from the bottom, heat it over an element, and release warm air from the top by natural convection.

What they all have in common is that they convert electricity to heat at nearly 100% efficiency. There’s no flue, no combustion, no water circuit — every watt you put in comes out as heat in your room. The difference between models isn’t efficiency in this sense: it’s how quickly they heat, how quietly, and how intelligently they manage the thermostat to avoid wasteful cycling.

Benefits of Using Electric Panel Heaters

The main advantage over traditional radiators is installation simplicity. There’s no plumber required, no pipework to route, and no boiler to size. You plug them in or hardwire them, mount them on the wall, and they work. For extensions, garden rooms, garages converted to home offices, and loft rooms, this is often the only practical heating option.

Wall-mounted panel heaters also free up floor space. In small rooms and hallways where every centimetre counts, a slim panel mounted at skirting board height or mid-wall can make the room feel considerably less cluttered than a traditional radiator or freestanding fan heater. Smart WiFi models add another layer of efficiency: proper scheduling means the heater isn’t running when the room is empty, which has a bigger effect on bills than the heater’s raw efficiency figure.

Things to Keep in Mind Before Buying

Wattage is the most important practical consideration. Too small and the heater will run continuously without reaching temperature. Too large and you’ll be constantly overriding the thermostat. The standard guide is 100W per square metre for a well-insulated modern room, rising to 150W per square metre for older properties with single glazing or poor insulation.

Think carefully about smart features. If you have consistent routines — you’re always in the room from 7am to 9am and 5pm to 10pm — a programmable timer does the job without any ongoing interaction. If your schedule varies, WiFi control and remote adjustability are worth paying for. And if you’re sensitive to noise, make sure the model you choose is specifically described as fanless or silent — convection and micathermic heaters are quiet, fan-assisted panel heaters are not.

Types of Electric Panel Heaters

Glass panel heaters have a glass or crystallite front that radiates heat outward. They’re visually the most attractive option and often the most featured-packed, but they’re also the most expensive. Micathermic panel heaters use mica-coated elements for near-instant, silent heat — they’re a step up from basic convectors without the price premium of glass panels. Traditional convection panel heaters are the most affordable type: simple elements, natural airflow, robust and easy to maintain. Infrared panel heaters work differently again — they heat objects and people directly rather than the air, making them efficient for spot heating but less effective for whole-room warmth.

Case Study: Heating a Home Extension in Bristol

Background

A family in a semi-detached house in Bristol added a single-storey rear extension to create an open-plan kitchen-diner. The extension measured approximately 22m² and was well-insulated with underfloor insulation and double glazing, but had no connection to the existing gas central heating system.

Project Overview

The family needed a heating solution that was cost-effective to install, controllable independently from the rest of the house, and capable of maintaining a comfortable temperature in a relatively large space. Running new radiator pipework back to the existing boiler was quoted at over £1,200 by a local plumber.

Implementation

They chose two Devola WiFi 2000W glass panel heaters — one at each end of the extension — wired into the ring main via a qualified electrician. Total installation cost was around £350, including electrician fees and the heaters themselves. Both heaters were linked via the Smart Life app and set on an identical 7-day schedule that mirrors the family’s typical usage pattern.

Results

In the first winter of use, the family reported the extension was consistently warm on arrival and that the scheduling had removed the need to think about the heating at all. Running costs worked out at approximately £38–£45 per month across the colder months, which the family considered reasonable given the space. The open window detection feature activated during periods when the bi-fold doors were opened onto the garden, automatically pausing heating and resuming when the doors were closed.

Expert Insights From Our Heating Engineers About Electric Panel Heaters

One of our senior heating engineers with over 18 years of experience working with domestic and light commercial heating systems shared his view on the panel heater market: “The biggest mistake people make when buying a panel heater is under-speccing on wattage. A 1000W heater in a 20m² living room will run flat out all day and never get comfortable. I always recommend going slightly above the minimum calculation — it’s far cheaper to let a 2000W heater run at half power via the thermostat than to have a 1000W unit struggle constantly.”

“The Lot 20 compliance question comes up a lot. In plain terms, it means the heater has been independently verified to meet minimum energy efficiency standards introduced by the UK government. It’s not a meaningless certification — it requires built-in electronic thermostats, open window detection, and adaptive start features. When I’m recommending a heater to a client, I always check for Lot 20 compliance first. It’s the quickest proxy for whether a heater is going to be efficient in real-world use.”

“On the smart vs. non-smart debate: the data consistently shows that programmable heating saves money over manual control. The discipline to turn a heater off when you leave a room simply isn’t there for most people — especially children. A WiFi heater with a schedule removes that variable entirely. For anyone spending significant time in a single room, I’d always recommend paying the extra for scheduling capability, even if you never use the remote app features.”
