5 Best Shed Heaters of 2024

As a company that design all sorts of clever kit, aimed at making your home more comfortable, it’s no surprise that ProBreeze make the best shed heater that I tested.

Their ProBreeze Mini Ceramic Fan Heater is more than enough for a small shed, with a maximum heat output of 2,000 W to play with.

It wasn’t that cold when I tested this electric heater, with 11° C outside, and a balmy 14° C inside. However, the superior firepower of this little portable heater was extremely noticeable. With temperatures leaping up 10°C in just 30 minutes, I wish I’d tested this out when it was 0°C outside. By the end of the test, it was 24° C inside and still rising. The heat output is definitely palpable.

Encased by smart white plastic, this is a rather good looking piece of kit. You get two dials on top to select the power levels and oscillation, and another one that works as a temperature control.

Boasting an impressive 2,000 W of power on its ‘high’ setting and 1,000 W on ‘low’, this garden shed heater has certainly got the power to heat up a small space. Unfortunately, you can’t use it as just a cooling fan in the summer unlike some of the other electric heater fans on the market. Also, it only oscillates through 60° so I felt it could have achieved more heat dispersion if it moved further.

Even though this electric heater lacks a fan mode for those hot summer evenings, it’s still a very practical bit of kit.

It’s a portable heater that’s easy to pick up and take with you which is useful when moving between different areas. Plus, thanks to the strong power output it won’t take long to heat up a small room.

However, one thing that might put you off this mighty 2,000 W heater is the noise output. I measured it to around 63 dB, which equates to the same noise as ‘conversation in a restaurant’ – quite a bit of background noise! Unfortunately, it’s a fair bit noisier than the other fan heaters and a lot harder to ignore.

This is the downside of having more powerful fan.

The temperature control dial is what makes this a very clever and energy efficient heater.

There’s an efficient built-in thermostat, so setting the dial between ‘min’ and ‘max’ will control how warm the room gets before the heater switches off automatically. Once the thermostat senses a drop in temperature, it pings back on, saving you from running the heater constantly.

Nevertheless, it is worth bearing in mind that on its high setting, this powerful fan heater will eat up electricity.

The ProBreeze is fitted with several safety features. It has anti-tip technology, which is relatively common in modern-day fan heaters. Plus, it has a wide trigger leg as well, so it will work happily on soft surfaces. The white textured case doesn’t get hot during operation either, which is a welcome touch.

Also, it’s only a little thing, but you also get a little red light to tell from a distance if the heater is switched on. It’s not a huge safety upgrade, but it might save you from bending down to check.

There’s automatic overheat protection built in as well.

This electric fan heater is slightly more expensive than the others that I tested. However, it’s also the most powerful fan heater, so at least it gives you a bit more bang for your buck. The build quality is good, and the ceramic heating element works very well.

When it comes to electric heating, it seems to be a simple case of the higher the Wattage, the more heat is produced. So, if you’re looking for the best fan heater to heat a small space, and are not overly concerned with price, this is a great option to consider.

Do bear the noise of the fan in mind though – it might be distracting if you’re trying to concentrate.

The Dreo Space Heater Atom One is a compact heater that’s ideal if you’ve got a small shed. This small heater measures just 17 x 14 x 26.2 cm and weighs just over 2 kg yet is capable of heating sheds up to 22 m³ in size. 

This heater has three heat settings: 1500 W, 1000 W and 900 W. On top of this, there are two modes: eco and fan-only. The eco-mode adjusts the power based on the ambient temperature and the fan-only mode can be used to cool your shed in the summer months. The heater oscillates through 70° allowing an even spread of air. 

For easy operation, this heater comes with a remote control that works up to 8 m away. There’s also a touchscreen LED display on the unit. 

There are a couple of features that help improve this heater’s energy efficiency. The first is an adjustable thermostat which allows you to set your preferred temperature from 5 to 35°C. 

On top of this, there’s a 12-hour timer so you don’t have to worry about forgetting to turn the heater off. It will also automatically turn itself off after 12 hours of inactivity.

Safety features include a tip over switch and overheat protection. 

All in all, this heater is a great choice for smaller sheds thanks to its compact design and light weight. The energy efficiency and safety features mean you don’t need to be constantly keeping an eye on it. 

If you’ve got a large shed that needs heating, the PELONIS Electric Space Heater has a powerful 2000 W heat output and can heat areas up to 35 m². It’s a great option for garages, sheds or workshops that get especially chilly. 

The heater is equipped with an eco mode that can help make it more energy efficient. It intelligently adjusts the heat output depending on the room temperature and will choose between the maximum 2000 W output or a lower setting of 1200 W. There’s also an adjustable thermostat which can is set using a simple control dial. 

This heater provides instant heat in seconds, and oscillates through 75° so the hot air is evenly spread around larger rooms. 

There’s an 8-hour timer, so you can set the heater to turn off after a certain period. Also, it will automatically turn off after 12 hours of inactivity to avoid the heater being left on by accident.

The heater is easy to control using the built-in touch-screen LED panel, but there’s also a remote control included for changing settings from afar. 

All things considered, this is one of the best shed heaters if you’ve got a larger space to heat. It has a powerful energy output and useful features such as the eco mode and adjustable thermostat.

If you use your garden shed as an office or workshop, you may not want a heater blasting away noisily. Thankfully, the Dreo Space Heater Solaris Slim H3 has made this list thanks to its quiet operation. Running at just 40 dB, this heater is almost as quiet as a library. 

With oblique airflow technology, wind noise is greatly reduced. According to Dreo, this heater is 12% quieter than traditional electric heaters, so you can work undisturbed. The heater is audible, but it produces quiet white noise which shouldn’t be too disruptive. 

Operating at 1800 W, with additional heat settings of 900 W and 1100 W, this heater is perfect for small-to-medium (15-25 m²) sheds. It oscillates smoothly through 70°, evenly distributing heat around the space.

There’s also an eco-mode, which will select the right power depending on the ambient temperature, and a fan-only mode. 

You can set the adjustable thermostat from 5 to 35°C and there’s also a programmable 12-hour timer. Also, in case you leave the heater on accidenally, it will automatically switch off after 24 hours of inactivity.

This heater also comes with a remote control, with an 8 m range, so you can adjust the settings without leaving your chair. 

Overall, this is one of the best shed heaters if you’re looking for a quiet fan heater that won’t disturb you while you work. 

From my testing, the DONYER POWER Space Heater came out as the best shed heater if you want a wall mounted option.

Featuring three power levels and a flexible heating element, it delivers efficient heating and is an absolute beast when it comes to pumping out heat. There’s a simple reason for this – on ‘high’ it produces a massive 2,000 watts!

I tested this electric heater when there was an outside temperature of 0°C and an inside temperature of 3°C (the coldest night in the shed, by the way). This heater brought the temperature up by 11°C in just 30 minutes. It took just over an hour to reach the target temperature of 20°C, which was rather impressive!

This halogen garden heater looks similar to the ones that they put on the wall in a pub garden. It’s a surprisingly light bit of kit, with three heating elements that deliver an impressive heat output. Operated with a pull cord, it clicks through three settings: 650 W, 1,300 W and 2,000 W.

It was easily mounted on my shed wall with four screws (included with wall plugs), but the mounting plate was rather thin and bent easily. For this reason, I’ve docked a point.

You can get a different version of the same heater with a tall stand, but one of the best things about this heater is that it’s up off the floor and not taking up any precious space.

If you can hang a picture on a wall without any problems, you can mount this electric heater in your shed. You simply remove the mounting plate from the back of the heater, screw it into the wall, and then reattach the heater. Simple!

I found the heater itself to be extremely practical. It doesn’t have a fan, so it’s silent, and with three heat levels you can decide how much heating power you need at any time. It provides near instant heat as soon as it’s turned on.

The only problem comes with the short power lead. Measuring just 1.8 m, it wasn’t quite long enough, considering it’s a wall-mounted item. I could position the heater at the top of the wall without resorting to an extension lead.

The beauty of having three different power levels is that you easily adjust the heat output. You can blast the room with three bars of 2,000 W heat to take off the chill, then knock it down to 650 W to keep it warm until the temperature drops again.

Unfortunately, being an infrared heater, as soon as you switch it off – you feel the cold air. This is a bit of a problem when the weather is cold out because you wouldn’t want to run this heater on full power all day long to benefit from constant heat – the cost would rack up.

As this is technically a patio heater and space heater, it’s perfectly capable of working safely both indoors and outdoors. Thanks to an IP24 rating, it’s protected against accidental splashes of water too. This means it’ll be happy sitting in a garden shed that might be a bit damp sometimes.

You can mount it high up on the wall, away from curious children and animals too.

In terms of additional safety features, it will cut out if it starts to overheat.

For the money, I rate this as an outstanding way to heat up a small shed. It’s not enough on its own to get a large internal area up to anything near 20° C, but its heat output made a noticeable difference in my 7 m³ space.

If you run it on its highest heat output (level 3) all day long, it will start to add up on your electricity bill. Keep it on low, and you’ll be a little bit better off.
