Best Electric Heater in UK – Top 10 Hottest List for Sep. 2021


Cold is cool until you are on the verge of freezing to death. Winter can get pretty intense in the Kingdom. If you are smart enough, you will do some serious research before buying an electric room heater to beat the chill.

While the fundamentals of how a space heater functions will always be the same, not every heater is suited for every environment. Ideally, it should neither be too small nor too big for your room.

Let's not also forget to address the alarmingly increasing cost of electricity per unit in the UK. It makes great financial sense to spend a little more on a low-energy consumption model.

To help you find the perfect size, energy-efficient space heater for your home or office, I present to you a selection of 10 best electric heaters for every need and budget.

10 Best Electric Heaters in UK for 2021

Best electric heaters over dozens of competitive models from different brands listed below:

ANSIO Heater Ceramic 2000W Mini Electric PTC Fan Heater

If you are looking for a portable PTC heater to bring the temp in an outdoor cabin or caravan, this one won't let you down. Its slim and compact stature completely belies its capacity.

The appliance can deliver an impressive amount of heat to a medium to large living rooms, dorm room, garage, conservatory, or office cabin in roughly 10 minutes. At the core of the heater lies a PTC heating element.

The cold air passes through the heating element and in turn, the machine circulates toasty warm air back into the environment. It's one of the fastest and most efficient ways to cool down a large room without shooting the electricity consumption through the room.

It comes with two power modes- low and high and a temperature control knob that acts as an adjustable thermostat to let you fine-tune the heat as desired.

As a safety precaution, the heater automatically switches itself off when the internal temperature is too high. So if you wish to leave the heater on 24/7, it's perfectly safe to do so.

Speaking of safety, it's also armed with a tip-over protection feature. The cut- off switch is at the base, meaning it will cut out the power if you accidentally tip it over.

Granted, the fan does make an annoying amount of noise but it doesn't take away from the fact that the heater is a steal for the price.

What I Liked:

  • Lightweight, can be dragged from one room to another effortlessly.
  • Low energy consumption.
  • Packs quite a powerful punch for the size.
  • Has overheating and tip-over protection.
  • Safe to leave on overnight.
  • Terrific value for money.

What I Didn't Like:

  • Quite noisy.

Dimplex OFRC15N Oil Free Electric Heater

More photo & price on

Dimplex oil-free heaters are a league of their own. The one I am reviewing is small enough to be tucked in a corner of a small garage or workshop without blocking the essential space.

It comes with caster wheels too, so you can move this little machine to the cold spot and turn up the heat in no minute. Don't let its tiny size fool you. It can efficiently warm up large rooms without fail.

There are two power settings on it- half (0.5kw) and full (1kw). For small to medium rooms, setting 1 (0.5kw) is usually more than adequate. For large spaces in an insanely cold climate, I'd suggest using the heater in full power.

It should be toasty warm in an hour or so. After then, switch back to setting 1 and leave it alone. The inbuilt thermostat will make sure to keep the temperature to your desired setting throughout the entire running time.

It's completely safe to keep the device on overnight to keep the frost away.

What I Liked:

  • The only noise it makes is soothing white noise.
  • Easy to assemble and carry around.
  • Has the capacity to quickly warm up large areas.
  • Oil-free, uses 9% less energy than oil-filled radiators.
  • Safe to leave it on overnight.

What I Didn't Like:

  • Not safe to use in or around wet areas such as the bathroom or laundry room.

The next entry on this list is a low power electric halogen heater, ideal for instant heating in small spaces. Made for both indoor and outdoor use, the compact heater is equipped with an on-demand oscillation feature to ensure an even and consistent distribution of heat all over the room for optimal satisfaction.

Instead of the more standard 2 power settings, it steps up the game by offering 3 power modes ( 400w, 800w, and 1200w) to help you adjust the heat output according to your liking.

On the downside, there's no thermostat. However, that doesn't prevent it from catering to its intended purpose. Even with one bar heated up, it produces a noticeable amount of it.

So, theoretically, running the device at full capacity should warm up standard size bedrooms or living rooms fairly quickly. Since there's no fan, it doesn't have that quintessential noise traditional electric heaters are commonly associated with.

What I Liked:

  • The heating bars are extremely sturdy and durable.
  • Cool-touch handle makes it safe to move around.
  • Can easily heat up large bedrooms when operating at full capacity.
  • Can make a noticeable change in the temperature in 5 minutes.
  • Has tip-over protection.

What I Didn't Like:

  • Doesn't have a thermostat. 

4. Dimplex OFRC20N Oil Free Electric Heater - (Great Budget-friendly Option)

Another oil-free Diplex model to grace this list, the OFRC20N has a timer to eliminate the need for constant manual adjustment. Since it’s oil-free, you don’t have to lose your sleep over leaking radiators.

With two power settings, it is well-suited for small to medium room sizes. When running at full capacity, it should take no more than half an hour to transform a damp, cold room into a lovely, warm atmosphere.

There’s an LCD panel on the heater body that displays the current settings. The built-in thermostat works fine. Just turn the dial at the front side to adjust the level of heat and you’re good to go.

In addition, it also has a frost control function, making it safe to use in conservatories and garages.

What I Liked:

  • Has a timer function.
  • Lightweight, hence easy to move around.
  • Tip-over protection and frost control.
  • Ideal for quickly heating up small to medium rooms.
  • The thermostat works well.
  • Not loud at all.

What I Didn’t Like:

  • Adjusting the dial takes some getting used to.

Next up, we have another portable, camper-friendly unit fitted with a cooling fan to ensure longevity of the heating element.

It comes with a remote control to bring all the adjustments such as heat setting, timer, cooling mode, and thermostat control at your fingertips.

The thermostat offers an adjustable temp range of 10-30 degree C to fit into a large variety of environment. The thermostat will cut off the power as soon as the heater hits the 65 degrees to prevent overheating hazard.

The fan is assuredly fast, making the exterior cool to touch in as little as 30 seconds. It’s a tremendously powerful heater, so you don’t necessarily have to sit too close to it to enjoy the toasty warmth to the fullest.

What I Liked:

  • Powerful cooling mode.
  • Rotates about 90 degrees on both sides to evenly distribute the hot (or cold) air.
  • Works very well in large spaces with several occupants.
  • The Fan Only mode eliminates stuffiness.
  • Remote control function and auto shut-off.

What I Didn’t Like:

  • Gets the bit loud when the fan is on.

6. Igenix IG1650 Portable Oil Filled Radiator Electric Heater - (Safest Electric Heater on Budget)

More photo & price on

Oil-filled radiators are one of the mightiest electric heater types to exist but they aren’t always the safest ones. To eliminate the oil leakage hazard these radiators are infamous for, the Igenix IG1650 has come up with a special leak-proof design.

The base is wide and heavy-duty for enhanced tipping protection.

It comes with castor wheels attached, so dragging to a preferred spot for the extra heat boost won’t be a problem. If you are looking to cut down on energy bill, it will be a good option to look into.

The metal on the heater retains high heat for a long time, so no need to run it at full capacity for more than half an hour or so.

The residual heat, combined with thermostat control ensures the machine is one only when it really has to be. Plus, it also gets brownie points for housing a silent oil-filled radiator. 

What I Liked:

  • Easy and straightforward controls.
  • Highly portable.
  • Can be used in laundry rooms.
  • Makes a difference in 5-10 minutes on low to medium settings.
  • Silent motor.
  • Extra-wide base for tipping protection.

What I Didn’t Like:

  • The wheels aren’t of the best quality.

7. DONYER POWER Electric Patio Heater - (Most Well-constructed)

DONYER POWER Electric Patio Heater

Here’s another halogen electric heater made with supremely heavy-duty heating pipes for instant and efficiency cooling. It needs to be mounted on a ceiling, which allows it to disperse the warm air more evenly all over the room.

Plus, it’s a considerably safer choice than free-standing heaters if you have a mischievous kid or pet in the house. The unit packs enough punch to combat the chill and frost at medium power settings.

When the heat is turned all the way up, it can fill up a decent sized room with toasty warm air in just a few minutes.

However, note that it won’t automatically turn itself off after reaching the target temperature as it has no thermostat. There’s nothing automatic about this machine.

What I Liked:

  • Gives lovely warmth if you sit right under it.
  • Suitable for both indoor and outdoor use.
  • The metal bars are built to last.
  • Stays hot for a long time even when turned off.
  • Very affordably priced.

What I Didn’t Like:

  • No auto shut down.
  • The cable length is ridiculously short.

8. Dimplex OFRB7N Electric Heater - (Best for Extreme Cold Weather)

Dimplex OFRB7N Electric Heater

This brilliant little 700w heater is way more capable of battling the typical UK winter than it looks. Since it’s an oil-free unit, the cost of running it isn’t expensive.

Moreover, the heating element remains hot long after it’s been shut-off. The residual heat can easily keep the chill away for about an hour.

The thermostat makes sure to turn the device back on when the room is cold again which minimises the need for supervision. It’s fairly lightweight too.

Moving it from one location to another won’t hurt your muscles, making it a great choice for camping, caravan, workshop sheds, or university halls where you need to keep the heater moving all the time.

You can also safely use it as a backup heating source in cloth drying areas.

What I Liked:

  • Easy and safe to move around.
  • No tipping or overheating risk.
  • Generates a good amount of heat for the size and price.
  • The motor noise is almost inaudible.
  • Easy to manoeuver.

What I Didn’t Like:

  • The cable should have been longer.

Russell Hobbs RHRETPTC2001G 1.5KW Retro Portable Ceramic Electric Heater

More photo & price on

This nifty little heater generates a quick burst of heat for an instant heat boost in a moderate size living room or office space. It offers 2 heat settings and a top-notch variable thermostat control for precise temperature level adjustment.

Brownie points for the cool touch interior. It is a much-needed safety feature, worth spending few extra on if you have a kid in the house. For optimal comfort on the coldest days of the year, keep it as close to your body as you possibly can.

The beast of a heater takes only 5 minutes to warm up and within 10 minutes on full power, the room should be toasty warm.

Make no mistake, the small size of the heater has nothing to do with its capability. It can warm up a large room faster than many of its larger, bulkier competitors.

What I Liked:

  • Automatically shuts down once it reaches the target temperature.
  • Heats up remarkably fast.
  • Is quite powerful for the size.
  • Has a striking retro design.
  • Suitable for garden rooms.

What I Didn’t Like:

  • The large, unquestionably unsightly warning sticker at the front doesn’t come off easily.

10. MYLEK Electric 2kW Over Door Fan Heater - (Most Technically-advanced Unit)

MYLEK Electric 2kW Over Door Fan Heater

More photo & price on

Unarguably the sleekest, modern technically-sound model on this list, this stylish above-door heater comes with a convenient remote control. Suitable for all weather use, It both heats up and cools down incredibly fast.

It works commedably well in large bedrooms and elevates the temperature to a comfortable level in no time. You can set the thermostat to 10-49 degrees.

The bright and clear LCD display shows all an array of settings including the “Fan Only” mode, weekly programmable timer, and basic timer. Installing the unit is a bit of a work, though.

On the bright side, despite being a fan heater, it isn’t obnoxiously loud. All you can hear is a mellow white noise which won’t come in the way of you and your peace of mind.

What I Liked:

  • Remote control operation.
  • Timer function and thermostat for auto-shut off/on.
  • Fan Only mode for cool air circulation in summer.
  • Both heats up and cool down really fast.
  • Energy-efficient.

What I Didn’t Like:

  • The setup instructions aren’t that easy to follow.

Final Verdict

So that was my two cents on the best electric heaters in UK. The choice is never easy with so many lucrative options on the table. The only way to be completely sure of your decision is to know what exactly you are looking for.

While budget might be the single most important determining factor for most of us, cheap, off-brand electric heaters with no proper safety feature are nothing but a liability.

Therefore, take your time to go through the product description, save up some more if you have to, and get yourself a heater you will be proud of buying.
