Best Pick: Benross 3000W Industrial Space Heater

A powerful and feature-packed heater

Powerful yet compact and portable, the Benross 3000W Industrial Space Heater would be a great choice for owners of small to medium garages.  

The 3000W heating element means you get plenty of power when you need it, but there’s also a 1500W setting, which is ideal on days that aren’t quite as cold and you don’t require as much power.

In addition to the heat settings, there’s also a cold air mode so you can use it as a fan during the summer too. It comes fully assembled out of the box so you’re able to start using it straight away and the carry handle on the top makes it very practical to move around.

The unit can be titled to any angle you desire, so you can have the heat directed exactly where you want. It’s also waterproof, so if the roof of your garage tends to leak after heavy downpours, you don’t have to worry about the heater being damaged.

Overall, this would be an excellent heater and would work well on its own, providing your garage isn’t too large.


  • Very easy to use with no assembly required
  • 2 heat settings mean you’re able to save money when you don’t require as much heat
  • Has a cool air setting so you’re able to use it as a fan in the summer
  • Dual overheat protection means it’s very safe to use

Gets the job done at a very affordable price

Our value pick is the Sunhouse SHTTH2 80W Low Energy Tubular Heater. If you’re looking for a way to heat your garage that’s low cost, then this is a great solution.

At just 80W, the 2ft long tubular heater is designed to run continuously and has a built-in thermostat, so you can easily control the temperature of the heat output. It keeps a very consistent temperature thanks to the thermostat, which switches on and off automatically as needed.

It comes with mounting brackets included and is very easy to fit. It’s also splashproof to IPX4 standard, always important when you’re installing any electrical equipment near the roof of a garage.

This heater would perfect for use in a garage, but you can also use it in any small space that you might not otherwise be able to heat, whether it’s a greenhouse, patio or shed.

Due to the low cost, it’s also practical to purchase multiple heaters if you’re trying to heat a larger area. There are also 160W version of this heater that are worth considering if you have a large garage.

Overall, the Sunhouse Tubular Heater is an excellent choice if you’re looking for something that will provide adequate heat without running up your electricity bill. 


  • Very affordable and does its job well

  • Its low power output means it does a good job of preventing a room from becoming too cold, but it doesn’t necessarily heat it to the same degree more traditional fan heaters do

Honeywell Heavy Duty Fan Heater

A great looking and high-quality heater

The Honeywell Heavy Duty Fan Heater is another excellent choice for keeping your garage warm during the winter.

The first thing you notice about this heater is its very striking look. It has a retro feel with its chrome trim and nobs, with the main body being a vibrant shade of red. Looks aren’t necessarily a primary concern when buying a garage heater but it’s always nice to add a little style to your garage.

Moving onto the functionality, it has 1800W of power, which makes it suitable for heating rooms that are up to 22m². This is one of a range of electric heavy-duty heaters from Honeywell. They also have 2500W and 3000W heaters, that would be suitable for heating larger areas.

It’s safe to use too, with overheat protection as well as tip-over protection, that will prevent the fan from operating if it’s tipped over – giving you added peace of mind. There’s also a marker on the unit that indicates whether it’s safe to touch or not.

It’s quite compact and portable, with a handle on the top making it easy to move around. It’s also quite a low cost to run compared to some other heaters on the market.


  • Has multiple safety features, including overheat protection, tip-over protection and a safeguard system
  • Looks good and heats the room very well


  • Is quite noisy, so it wouldn’t be ideal if you like to listen to the radio when working in the garage

Pro Breeze 2000W Mini Ceramic Fan Heater

Energy-efficient yet still has plenty of power

The Pro Breeze 2000W Mini Ceramic Fan Heater is an impressive offering for a few reasons.

It makes use of ceramic heating technology, making it energy efficient while still being able to heat the room where it’s placed very well. It has a built-in thermostat and four operation modes so you can easily control the heat in the room as well as how much power it uses.

At the highest setting, it uses 2000W so it’s certainly powerful enough to heat smaller garages on its own. It also has tip-over protection, which will stop it from operating if it’s knocked over.

Something this heater has over plenty of others in its price range is that it oscillates. This means the heat is evenly distributed throughout the room rather than being concentrated in one area. This makes it very good in larger garages where you have more space to heat.

The unit weighs just 1.75kg and has a carry handle on the top so it’s very portable and easy to move around.


  • Ceramic heating technology makes it energy efficient without compromising on heating power
  • At just 1.75kg it’s very lightweight and easy to move
  • Oscillates at 60 degrees, so you get very even distribution of heat throughout the area it’s used


  • May not be powerful enough to heat larger garages
  • Some reviewers had issues with the heater breaking after a few weeks of use

How Much Does It Cost To Heat A Garage?

There are a few things that will determine how much it costs to heat a garage, the main ones being –


Firstly, and most obvious is how much you use your heater(s). If you do a lot of work in the garage during the winter, then keeping it heated constantly can become quite costly, depending on the power output and the number of heaters you use.

The size of your garage

If you have a large garage, then you’re likely going to need multiple heaters to keep it warm. This will, of course, add to the cost.

For example, if you’re using 3000W heaters, then it’ll cost around 43p per hour to run each one. Having multiple heaters running at this rate means the price can add up quite quickly.

The power of the heater

The power of your heater is another thing that will affect cost. Electric heaters can vary quite a lot when it comes to how much power they use. You should consider the size of your garage and how much power you’ll need when choosing an electric heater since it’s easy to end up overspending unnecessarily.

How Best To Heat A Garage Cheaply

Although electric heaters do a good job of keeping a garage heated, they’re not always the best solution due to the running costs.

Below are some great alternative ways to heat your garage cheaply during the winter.

Insulate doors and windows

An obvious way to keep your garage warm at a low cost is by properly insulating it. Insulating doors and windows is a very easy DIY task and something you can do in a relatively small amount of time.

In addition to insulating the interior of the garage, it’s also a good idea to weather strip the exterior doors. This will certainly help when there are storms or heavy winds that can easily create a chill inside your garage.

The winters in the UK can be quite harsh, so insulating on its own might not be enough to make your garage warm but it will help you to prevent loss of heat and therefore keep your heating bill to a minimum.

Install a wood burner

A wood burner can be an excellent way to heat a garage cheaply, providing your garage is set up for it. Once it’s installed, the only real expense would be the wood for fuel.

It’s important to stress that you should only consider this option if you’re confident it won’t cause any safety issues. You should also check with your insurance company to see if you’ll still be covered if you have a wood burner in your garage. Not all providers will allow you to do this so it’s certainly something you need to be sure of before you install one.  

Have a radiant heating system installed

Radiant heating systems enable you to heat your garage by having panels installed in the walls, the ceiling or under the floor. Infrared technology is used to heat the surfaces where they’re installed rather than the air itself. Under-floor heating is a particularly good option since it ensures even heating throughout the garage.

It can be quite costly to have a radiant heating system fitted initially, but once it’s installed, the operating costs are very low so it’s certainly an option worth considering.
