The UK's bestShed Heaters2022 Review

There’s nothing worse than trying to work in a freezing cold shed. If you want to avoid numb fingers and frozen toes, you need an efficient way to keep warm. That’s why I’ve tested out some of UK’s most popular shed heaters…

How I Tested the Shed Heaters

It’s important that you consider the size of your space if you want to get the best shed heater for your money. My shed is small but perfectly formed. There’s enough room to potter about, but a little fan heater can still heat it up considerably.

I worked it out to have 7 m³ of internal space. However, that’s still nothing compared to a two-car garage – don’t expect a single 1,200 W fan heater to noticeably raise the temperature in any cavernous space!

To make this a proper side-by-side test, I spent five evenings testing five heaters in my shed and recorded the temperature outside and inside with a digital thermometer. Aiming for a target of 20° Celsius, I started the stopwatch as soon as I switched on the heater.

N.B. I felt that 3 out of the 5 shed heaters I tested are not worth recommending. Therefore they have been left off my list below.

    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 free-standing shed fan heater that I tested.

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

    It wasn’t that cold when I tested this heater out, with 11° C outside, and a balmy 14° C inside. However, the superior firepower of this little heater has 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.


    Design – 4/5

    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’, it’s certainly got the power to heat up a small space. Unfortunately, you can’t use it as just a fan in the summer unlike some of the other 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.

    Practicality – 3.5/5

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

    It’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.

    Energy Efficiency – 4/5

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

    Safety – 5/5

    The ProBreeze 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 overheat protection built in as well.

    Value for Money – 4/5

    This 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, so it should last for a long time.

    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.

    Overall – 4.1/5


    • Efficient at quickly heating small spaces - can raise temperature by 10°C in 30 minutes (in a 7 m³ area)
    • Built-in thermostat switches heater off and on automatically in order to save energy
    • Case does not get too warm or hot to touch
    • Choice of two heat settings makes it easier to conserve energy when desired
    • Red light makes it easy to tell from a distance whether the heater is switched on


    • Noisy fan reaches around 63 dB which could be distracting during certain jobs
    • Small oscillation arc of 60°
    • No cool fan setting means this is only useful during cold weather and doesn't double up as a fan for summer

Best wall-mounted shed heater
DONYER POWER Wall Mounted Infrared Space Heater

    The DONYER POWER Space Heater was the best wall mounted shed heater that I tested out. Featuring three power levels and a flexible heating element, it’s 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 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!


    Design – 4/5

    This 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 put out an enormous amount of heat. 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.

    Practicality – 3.5/5

    If you can hang a picture on a wall without any problems, you can mount this 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 heat you need at any time.

    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.

    Energy efficiency – 3.5/5

    The beauty of having three different power levels is that 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. This is a bit of a problem when it’s cold, because I wouldn’t want to run this heater on full power all day long either – the cost would rack up.

    Safety – 5/5

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

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

    Value for money – 4/5

    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 made a noticeable difference in my 7 m³ space.

    If you run it on level 3 all day long, it will start to add up on your electricity bill as well. Keep it on low, and you’ll be a little bit better off.

    Overall – 4/5


    • Powerful enough to raise temperature by 11°C in 30 minutes (in a 7 m³ area)
    • Useful if short on room as wall-mounted design is not using any floor or desk space
    • Can be mounted out of reach of pets and children
    • Three heat settings mean there is some control over power usage
    • Silent heater will not distract from work or listening to music


    • As soon as the heater is turned off, a dramatic reduction in heat can be felt
    • Power cable is a little short at 1.8 m which may be inconvenient for mounting the heater high up on a wall
    • Mounting plate may bend easily - could be of higher quality

How to Choose The Best Shed Heater

Whether you use your shed as a home office, or want somewhere to warm up after a cold morning gardening, there are plenty of low-cost garden shed heaters that will keep out the chill. Heaters can also ensure that plants, tools and paint don’t freeze during winter.

They don’t have to be used exclusively in sheds either, and can be a valuable addition to garages, summerhouses, conservatories and greenhouses as well.

There are several types of  heater to choose from, including: electric radiators, fan heaters, halogen heaters, tubular heaters and paraffin heaters. Many of these are very efficient and don’t cost too much to run. Paraffin heaters allow you to heat a shed or greenhouse to keep it above freezing even if you don’t have an electricity supply to the building.

Finding the best shed heater will depend what you need it for, so the following information should help you work out which one to choose:

The Different Types of Heater

In the list of ‘best shed heaters’ below. you will notice that there are several different types of heater featured. They all have different attributes and varying advantages and disadvantages. Here are the different styles of heater available and what they’re best used for:

Electric Radiators

Electric radiators look like classic radiators; however, they’re mounted on wheels and can be easily moved around.

In the past, these radiators always contained oil which would heat up and keep the radiator warm. Nowadays, there are oil-free versions available. These are often more economical to run and more environmentally friendly than oil-filled radiators.

Electric radiators are generally considered to be the most economical type of convection heater. Heaters that use convection warm up the air in a room, instead of just heating up surfaces via radiant heat whilst they’re on. As a result, when using an electric radiator, the overall temperature of the room will increase.

Even when the radiator is switched off, the room will remain warm for some time (depending on how draughty it is). This isn’t the case with heaters that use radiant heat.

Electric radiators are a safe, versatile and cost-effective way to provide heat in a variety of situations.

Fan Heaters

Fan heaters provide instant heat and can warm up a small room relatively quickly. They’re good at circulating air, and work continuously to heat cold air and create warm air.

However, they are more power hungry than a lot of other heat sources. The fan tends to use a lot of energy, and so does heating the air. This means they are more suitable for quick blasts of heat for short periods, rather than keeping a room warm all day.

If you buy a fan heater, you should be careful about power consumption – it can be tempting to leave them on for long periods which can wind up being quite expensive. Look for a fan heater with a thermostat to help keep costs down; these will save on power by turning off when the desired temperature is reached.

Halogen Heaters

Halogen heaters use halogen bulbs to provide heat. These are the types of heating ‘lights’ often seen outdoor pub areas, but smaller versions are available for home heating.

They use radiant heat, which means they heat surfaces instead of the air. As a result, you will feel warm when sitting in the glow of the heater, but cooler as soon as it’s off.

Halogen heaters tend to be relatively cheap to run, and if they come with two or more bulbs, you can choose how many bulbs to have on, and therefore how much power to use. This gives you control over how much it will cost to run your halogen heater.

Often, halogen heaters come with some built-in safety features, so this is something to look out for. For example, many will cut out if they are tipped over or fall.

They can require some maintenance because the halogen bulbs will need to be replaced from time to time. However, the bulbs are generally long lasting.

Low-Energy Tube Heaters

If you simply want to keep a room or outbuilding frost free, then a low-energy tube heater is a good option to consider.

These are designed to provide steady heat and protect rooms from frost, condensation and damp. If you need to keep your greenhouse, shed or garage frost free then these are a simple, low-cost solution.

They are best used in relatively small sheds, no bigger than 2.4 x 1.8 m (8 x 6 ft); however, more than one tube heater can be used if you have a larger space.

They will not make the shed feel particularly warm, and probably won’t turn it into a comfortable environment to work in during winter, but they can protect plants from frost and stop tools from being damaged by freezing temperatures.

Paraffin Heaters

Paraffin heaters are the best shed heaters to buy if there is no electricity supply available.

They are cheap to buy, simple to use and reasonably cost-effective to run. Modern paraffin heaters are also relatively safe to use, though you should follow all instructions and safety guidelines provided by the manufacturer carefully. One drawback is that you will have to buy, store and safely dispose of paraffin, which can be an extra fuss for those who aren’t used to doing so.

Paying an electrician to install an outside mains power supply in the garden might be worth considering. This can make many aspects of gardening easier, not just heating. As well as giving you the option to use electric heating outside, an outdoor socket can be useful for running power tools and lighting as well.

Convection or Radiation Heaters

Not all heaters go about heating in the same way.

Heaters that use ‘convection’ heat up the air around the heater. Once that air is warm, it rises pushes cooler air out of the way. This process creates a cycle of warm air moving through the space.

Heaters that heat via convection: electric radiators, fan heaters, tube heaters and paraffin heaters.

On the other hand, heaters that use ‘radiation’ do not focus on warming up the air. Instead, they directly pass heat to any objects in front of them.

Heaters that heat via radiation: halogen heaters.

As a result, convection heaters are generally better for heating a room, whereas radiation heaters are better at providing quick blasts of heat when you feel it’s needed.

Safety Precautions

Be aware that there are some health concerns connected with using a paraffin heater in an enclosed space. Mainly because, through their process of fuel burning, they release pollutants such as carbon monoxide, nitrogen oxides and sulphur dioxide. As a result, it is generally recommended to use these heaters with a window open.

Avoid leaving heaters switched on and unattended as much as possible. Although many of the best shed heaters have safety functions, generally meaning they will turn off if they start to overheat, you can never be too careful when it comes to a heating device.

Shed Heater FAQs

I need to keep my garage frost free to ensure my freezer and dehumidifier work properly. What type of heat source would you recommend?

To keep an area frost free, low-energy tube heaters are a good option to consider. They cost very little to run and are capable of keeping small spaces, like garages, above 0°C. Depending on the size of your space, you may need to buy two. This is often the case in areas that are bigger than 2.4 x 1.8 m (8 x 6 ft). These tube heated can be wall mounted or floor standing, and you can also buy protective metal housings for them – this can be a good idea if there is a chance that children or pets will come near them.

What type of heater should I use to keep my rabbit house warm over winter?

There are a couple of options that will work in this situation. You should bring the rabbit hutch inside, into either a shed or garage and work on heating the space to keep the hutch warm.

Make sure that whichever option you choose is safe to use in an enclosed space. The first option to consider is a low energy tube heater that will keep the room frost free. These will keep the temperature inside a small shed above 0°C even when the temperature outside is below freezing. Metal housings can be bought for these to make sure pets and children can’t get too close to them – they get quite hot to the touch.

The other option is to use an oil-free radiator with a frost-free setting which will also be safe and economical to run.

Will the tools in my shed be damaged by freezing conditions over winter?

Damp, freezing conditions can have an adverse effect on a range of items in your shed. Paints can freeze, metal tools can rust, and plastic parts can become brittle. In addition, the grease and other lubricants in power tools can freeze as well.

You only need to keep the shed just above freezing to prevent this damage, so should look for a heater that will protect the space from frost. A low-energy tube heater is normally the most cost-efficient and effective way to do this.

Before using any tools, you should allow them to warm up to room temperature.
