Say hello to a heater that looks nothing like a heater. Which, to be clear, is a good thing. This sleek piece of kit, designed for rooms of up to 30m², has a monochrome matte exterior which ensures it won’t clash with your carpets or cushions, and it heats up incredibly quickly. Duux claims it heats up three times as fast as your average heater and it took just a couple of minutes to warm our entire living room.
There’s a nod to retro style with this heater, thanks to its sleek design which brings to mind an old-style radio with chunky knobs on either side of the extra-wide carrying strap. We loved the smoothness of the controls, which made it ridiculously easy to alter the fan speed and temperature by two large dials. Plus, it’s another one that ticks the versatility box – during hot sticky days (remember those?), there’s the option to use the fan alone.
This compact heater is great for smaller homes – it heats up relatively quickly and can be easily stashed away when not in use. We loved the look and feel of the controls, which require the lightest of touches and but lie flat and low to minimise the risk of accidental knocks.
This compact heater reminded us of the wind machines used in films to give Hollywood superstars that sexy windblown look, although that’s where the similarities end. Its cheery ruby exterior (picture a pair of cherry red Dr Martens boots and you’ll know the colour we’re talking about) offers a welcome alternative to the usual greys and blacks used for heaters, and the brilliant dial-style controls make it easy to fully customise the heat output.
Dyson purifier hot and cool formaldehyde purifying fan heater
First, let’s address the elephant in the room: the name, because let’s face it – “formaldehyde” isn’t top of the list when it comes to words we look for in the name of our heater. But we were pleased to learn it refers to the heater’s ability to kill the chemical (although we suspect there’s not a huge amount of it in the average household).
Russell Hobbs retro 1.8kw horizontal/vertical grey fan heater

We’re into the summer months now, but that doesn’t guarantee warmer weather for everyone. Whether you live somewhere that doesn’t get much sunlight or in a draughty house, the best electric heaters can help keep you cosy and comfortable all year round.
It’s easy to spend a lot of money on an electric heater with fancy functions, techy designs and promises of “energy-efficiency”, but keep in mind that the cheapest heaters do exactly what the pricey ones do: they convert electricity into heat through resistance.
Because all electric heaters run at near 100 per cent efficiency, you can ignore any claims about one heater being cheaper to run than another. The most important difference is the wattage – the rate at which the heater draws electricity – which means more heat and a bigger bill. The trick is to choose the wattage that’s appropriate for the size of the room you’re heating. Too small and heat will dissipate away too quickly.
Features we’d suggest looking out for when shopping for a portable heater include digital displays, timer functions and remote control functionality, all of which make it easier to crank up the heat without having to emerge from your blanket or bed.
These heaters were tested during the winter cold snap. We took our testing incredibly seriously, cranking up temperatures to the max and putting the devices through their paces, whether it was by lugging them to different rooms to examine their ability to warm spaces of different sizes or timing how long they took to achieve maximum heat.
In short, it was hot, sweaty stuff. Although, on the plus side, we’re pretty certain our calorie burn was similar to that achieved by an hour in a Swedish sauna.

Duux claims it heats up three times as fast as your average heater and it took just a couple of minutes to warm our entire living room.
We loved the design of the air outlet, which ensures an even distribution of warmth and eliminates the risk of heat-hogging dogs, cats and kids turning into trip hazards. Irrespective of where we sat, we enjoyed constant, even heat. The Duux, which has two fan speeds, three heat settings and a temperature range between 22C and 30C, can be tweaked using the control panel on the device or an app.
The grey colourway is currently unavailable, but the white version is still in stock.

This compact heater is great for smaller homes – it heats up relatively quickly and can be easily stashed away when not in use. We loved the look and feel of the controls, which require the lightest of touches and but lie flat and low to minimise the risk of accidental knocks.
We could quickly scroll between the two fans speeds and choose between temperatures of 25C and 35C, and once the cold winds of winter have passed, it can be used as a fan or air cooler too (you’ll need to fill a small tank at the rear in order to use the latter feature).
Extra features: Thermostat, two heat settings, overheat protection, adjustable tilt angle

This compact heater reminded us of the wind machines used in films to give Hollywood superstars that sexy windblown look, although that’s where the similarities end. Its cheery ruby exterior (picture a pair of cherry red Dr Martens boots and you’ll know the colour we’re talking about) offers a welcome alternative to the usual greys and blacks used for heaters, and the brilliant dial-style controls make it easy to fully customise the heat output.
One of the dials can be used to crank up the temperature by tiny increments, while the other allowed us to choose between half power or full power, and to use the heater with the fan or without. It’s easy to operate and we loved the smoothness with which the fan could be tilted back and forth. Our one gripe? The cable, which comes in at a measly 1.3m.

But we were pleased to learn it refers to the heater’s ability to kill the chemical (although we suspect there’s not a huge amount of it in the average household).
Formaldehyde fearmongering aside, this heater, launched in early 2021, is a great, compact appliance that quickly warms medium and large rooms (it oscillates up to 350 degrees) and is easy to use, thanks to its app, voice control and remote control functionality. The upside of the eye-watering price tag is that it cools and purifies too, and top-notch Hepa filters make it especially suitable for allergy-prone people.

Maximum output: 1,800W
Extra features: Two heat settings, fan only option, overheat protection

Russell Hobbs’s newest heater is on-trend, surprisingly powerful and costs less than £25. With coverage of up to 20m², it’s perfect for bedrooms and can be used vertically or horizontally – a great feature for teens’ bedrooms, where space is often at a premium.
The controls – which are easily accessible, irrespective of the heater’s position – make it easy to switch between the two power settings and turn up the heat, while the built-in handle ramps up the portability.
How energy efficient are portable heaters compared to central heating?
This depends on what you are trying to achieve. When it comes to heating an entire home, or anything more than one room at a time, then central heating – and gas-fired heating in particular – is the way to go.
However, if you only wish to heat one room – say you are working alone at home, so only need to warm your workspace for a short time – an electric heater can make most sense. Remember, these are called space heaters for a reason; they are designed to heat the specific space they are in, not an entire room or home.
As for energy efficiency, electric space heaters are considered 100 per cent efficient because they use all of the electricity they consume to produce heat. On the other hand, a gas boiler ignites the gas to heat water, from which heat then travels outwards from your radiators and into the surrounding air.
In short, central heating is best for warming an entire home, or a floor of your home, while an electric heater is best when used for short periods to heat a single room.
