Written by April Foot

If you spend a lot of time in your garden shed, a shed heater will help to make that a more pleasant experience.

Whether you’re potting plants in early spring, working on a winter project, or using your outbuilding as an extra room to relax in, a shed heater will help to keep you warm and make your shed a more inviting environment. 

There are several types of shed heater, from wood burners to propane and halogen heaters, but the most common are powered by electricity, and require a power source to function. Depending on the size of your space, a fan heater may be sufficient, or you may need to invest in a radiator.

If you’re looking for a shed heater to stop you shivering, we’re here to help. In this article, we compare 5 of the best shed heaters on the market, based on their heat output, energy efficiency, and value for money.

Your shed will soon be so warm and toasty, you won’t want to leave!

Best Pick: Pro-Breeze 2000W Mini Ceramic Heater

Our best shed heater is a ceramic fan heater with 2 power settings, and automatic oscillation – perfect for warming small spaces

This Pro-Breeze 2000W Mini Ceramic Heater has an impressive heat output for such a small and affordable heater, and wins the title of our best pick. Pro Breeze are world leaders in heating and cooling technology, and their expertise shows in this high-quality design.

The heater has 2 power settings, so can run on high (2000W) or low (1200W), and an adjustable thermostat gives you full control over the amount of heat created. Ceramic heaters are quicker to warm and more energy-efficient than traditional fan heaters.

Optional 60° automatic oscillation disperses heat, meaning that it is capable of warming a larger space, not just the object/air immediately in front of it – although there is also the option for this, if you prefer.

An overheat protection function and anti-tip-over switch will cause the heater to cut out in unsafe conditions, affording you peace of mind. Measuring 18.5 x 15.5 x 26cm, it has a lightweight and portable design, and a built-in carry handle makes it even easier to move the heater around your shed as you work. 

This might not be our most affordable heater, and it is a little noisy when it’s running, but considering the heat on offer, it’s still an incredibly good value option, from a reputable brand.

Pros

  • Advanced ceramic fan heater.
  • 2 power settings – 2000W and 1200W – and adjustable thermostat.
  • 60° automatic oscillation disperses heat around the room.
  • Quicker and more efficient than traditional fan heaters.
  • Built-in overheat and anti-tip-over protection.
  • Lightweight and portable.

Cons

  • Runs quite loud.
  • Not the cheapest option.

Value Pick: Dimplex Tubular Heater

Our best value heater has a low output and won’t heat your whole shed, but it might keep frost and damp at bay

The Pro-Breeze is extremely reasonably priced, but if you’re looking for something even more affordable, you could try this Dimplex Tubular Heater, to keep the chill off your shed.

This 2ft thermostatic tubular heater is a different style of heater to the ProBreeze, and can be mounted on the wall in your shed. It comes with discreet mounting brackets to make this possible, and takes up very little space.

It has a considerably lower power output of 40W, and produces much less heat than the ProBreeze. It’s suitable for small cupboards and could stop frost and damp from setting in (multiple heaters may be required), but it isn’t capable of heating an entire shed.

On the plus side, it is our most affordable heater, and it is cheap to run – one user reports that running the heater on full power, 24 hours a day, cost them less than £4 a month.

However, there’s a reason it’s so cheap. To be honest, unless you have an extremely small shed, or are only looking for something to prevent frost, it’s worth paying a little more for a proper heater, with effects you can truly feel and appreciate.

Pros

  • One of our most affordable shed heaters.
  • Small size takes up little space.
  • Includes discreet brackets for easy wall mounting.
  • Reversible cable entry expands your installation options.
  • Highly economical – can be run on full power 24/7 for only a few pounds a month.
  • Helps prevent damage from frost and damp.

Cons

  • Emits a limited amount of heat, compared to a fan heater – won’t warm up a room.

Benross 2.8kw Industrial Fan Heater

This powerful ceramic fan heater is multi-functional, as you can also use it as a normal fan, to keep cool in summer

It’s back to something a bit warmer for our next heater, which is this Benross Industrial Ceramic Fan Heater. With 2.8kw of power behind it, it’s more powerful than the ProBreeze heater, and is more than capable of heating an average-sized shed.

There are 2 power settings, so if you don’t want quite such a toasty 2800W, you can turn it down to a milder 1400W. Those who use their shed year-round will be pleased to know there is also a standard fan function, to help keep you cool on hot days.

There’s no oscillation feature on this one, so the heat will be thrown out in one direction only, and you might need to move it around to warm a whole room. However, this isn’t too difficult, thanks to the built-in carry handle, and small size. Measuring 22.5 x 12.5 x 38.5cm, it’s slightly larger than the ProBreeze, but still lightweight and portable.

The heater is designed to be energy-efficient, and emit a low noise – although it does make a noticeable sound whilst running, so bear this in mind. There’s also a built-in overheat protection, to keep you safe.

All these features do come at a price, as this is our most costly shed heater – but for something this powerful, we think it’s more than worth it.

Pros

  • Powerful ceramic fan heater, with durable metal casing.
  • 2.8kw output will have no problem heating a room.
  • Can also be used as a fan in summer.
  • Energy-efficient and low noise design.
  • Easy to move around, thanks to the small size and carry handle.
  • Built-in overheat protection.

Cons

  • Our most expensive shed heater.
  • No oscillation function, to disperse heat.

Sunhouse Low Energy Heater

Take the chill off a small space for very little cost with this energy-efficient tubular heater

This Sunhouse Low Energy Heater is another 2ft long tubular model, with a low level of heat output – but it does have more power than our value pick, at 80W. There’s also an adjustable thermostat, so you can control the amount of heat on offer, and keep your space at a consistent temperature (albeit, not a particularly hot one!)

This type of heater is designed to emit a low amount of localised heat, and is efficient enough to be left on continuously. This makes it ideal for taking the chill off a specific area of your shed, or preventing frost and mold during winter.

It is more powerful than the Dimplex, and could work well installed under a desk, if you use your shed as an office, to keep your legs warm. However, it still won’t throw out enough heat to warm a whole space, so if this is what you want, you’d be better off with a fan heater.

The good thing about this type of heater is that it’s safe, and affordable, to leave on all the time. It’s also splash-proof, so you don’t need to worry about using it in damp conditions.

Pros

  • Small 2ft tubular heater, takes up very little space.
  • Built-in thermostat allows you to adjust the temperature.
  • Low cost and cheap to run.
  • Highly energy-efficient.
  • Helps keep frost and damp away from your shed.

Cons

  • Low level of heat output, compared to fan heaters.
  • Localised heat only – won’t heat an entire room.

Hylite Ecoheater 500mm Greenhouse & Shed Heater

This low-energy heater is ideal for keeping your shed or greenhouse temperature above zero, to protect plants

Our final shed heater is this Ecoheater 500mm Greenhouse Heater by Hylite. With an output of 55W, it’s mid-way between the other two tubular heaters, and emits a low amount of localised heat, to benefit the immediate area and take the chill from the air.

Features include IP44 water resistance rating, to give you peace of mind when it’s installed in damp environments, and an adjustable thermostat, so you can set it to your preferred temperature. This also causes the heater to switch off when the desired temperature is reached, preserving energy.

The heater can be wall-mounted, or freestanding. Again, when evaluating this one, it depends on your reason for heating your shed. If you want to warm the whole room, to make it a comfortable environment for you to spend time in, this probably won’t be suitable, unless your shed is tiny.

However, if you’re looking for a cheap solution to keep damp and condensation away from your outbuildings, or to stop your greenhouse temperature dropping below freezing, this might well be all you need – and you can’t beat it on running costs.

Pros

  • Small, affordable tubular heater.
  • Ideal for preventing frost, damp and condensation in your shed.
  • Built-in thermostat enables you to adjust the temperature, and switches the heater off when the surrounding area gets too warm.
  • Energy-efficient design ensures a low running cost.
  • Water-resistant and easy to clean.

Cons

  • Comparatively low heat output.
  • Not suitable for heating a whole room.

Tips To Keeping A Shed Warm

The easiest way to keep an existing shed warm is to install a heater, such as those featured here. Choose from electric or water-powered radiators, fan heaters, or halogen heaters, depending on the size of your space, and whether you want localised heat, or the whole room warmed.

Other than bringing a heater into your space, there are several other things you can do to keep your shed warm. One of the most important of these is insulation – use foam boards to pad out the ceiling, floor, and walls of your shed. A well-insulated shed will not only keep you warm in winter, but also cool in summer, and will help to keep your energy bills down.

If you have an overhead light installed in your shed, you could try replacing the light bulb with an infrared heat bulb, such as those used to keep baby animals warm. This will produce heat, and help keep your shed cosy.

Another way to keep your shed warm is by installing under-floor heating. This is a luxurious and pricey solution, that will involve taking up the entire floor of your shed, and is probably only worth it if you use your shed on a daily basis, as an outdoor office or workshop.

How To Keep A Shed Warm Without Electricity

A common problem many people face in keeping their shed warm is the lack of an outdoor electricity source. In this case, you could use a portable propane heater, which runs on gas, and doesn’t need to be plugged in.

Alternatively, you could consider installing a wood burner. Not only will this heat your space, but it will give your shed a cosy, log cabin feel. Just make sure to have it professionally installed on a heat-proof surround, and add a carbon monoxide alarm, for safety.

Although they can be expensive to install, wood burners are powered by logs, which can often be sourced for free, or very little, especially if you live in the countryside. This makes them highly affordable to run. Another, eco-friendly option for heating your shed is a solar-powered heater. For this, you will need to install solar panels on the roof, which can then be used to power a small radiator. The output will be affected by the weather, and again, installing this system can be pricey – but once it’s set up, solar energy is free!
