Garages are the most neglected area of a house when it comes to heating. I don’t want that to be the case for you. So I’ve researched the best types of garage heaters for each price range and passing that onto you.

All of these garage heaters will be electric, which, in my opinion, is the best way to heat your garage.

Why it’s Worth Investing in Top of the Range Garage Heaters

Investing in a high-quality garage heater can last you years, I’ve had cheap heaters after cheap heaters. Anything under the $50 price range honestly only lasted me a few months at a time. Don’t make the same mistake I made, buy the right garage heater once and you won’t need to buy again.

There are other ways to heat your garage too, such as getting a radiator installed or heating under the floor. Personally, I’ve never been a fan of this, electric heaters are so much easier to install. Don’t put extra strain on your boiler, and can heat up your garage in a matter of minutes.

So, if you’re like me and you want to avoid a labour/service fee and getting your garage turned upside down, opt for an electric heater for your garage. You’ll find that it will save you time and money. It also offers more flexibility if you decide to use the heater for another room in your house.

Garage Heating Tips

Now that you’ve chosen what heater you’ll buy or how you’ll heat your garage, it’s worth just reminding you of a few things to get the most out of your heaters.

Insulate Your Garage

I spoke about garage insulation in my garage conversion article. For more guidance on how to insulate your garage, I would suggest giving it a quick read. The purpose for doing so is that there’s no point heating your garage up if your garage isn’t properly insulated.

Warm air will escape through your garage meaning you’ll have to heat your garage for longer, making it more expensive for you. My guidance would be to just ensure each part of your garage is insulated. This includes the garage door, the ceiling, the other door (assuming you have one), the windows, and of course, the walls.

Consider the Size of Your Garage

Double or triple garages may require two electric heaters instead of one. This again depends on how good your insulation is. If your garage is well insulated, you may get by with one heater (given it is of good enough quality), it will just take a little bit longer to heat up.

A good way to decide this is by looking at the BTU of your electric heaters, the higher the better, especially for bigger garages. Just keep an eye on costs, although typical 1500-watt electric heaters will only cost you 15 cents an hour on average.

Where you Live and what your Garage is For

If you live somewhere cold, it may be worth getting more permeant heating installed and maybe using the electric heaters for when it’s not freezing. Likewise, if you live somewhere warm with mild winters, it’s worth using an electric heater when you find it chilly.

Also, consider what you use your garage for. If you’re using your garage for manual work, it’s likely you won’t need a really powerful heater. However, if you use it as a multi-purpose, family space for comfort, it will be worth investing in a high performing heater.

Power Supply

Finally, as these heaters are electric, it is worth considering your power source. If you’re garage doesn’t have any or enough outlets, it may be worth getting one installed or using an extension lead. If you opt for the later, just remember the trip or fire hazard that come with it. However, as long as you’re not over-doing it with the extension leads you should be fine.

I’ve also only recommended electric heaters with high quality safety standards so you can warm yourself and your family up with peace of mind.

Final Thoughts

If you’re like me and you can’t stand the cold, then it is well worth investing in the right garage heater for you. In my opinion, electric heaters are better in garages because they offer more versatility. They are also much easier to install than any other type.

Using the electric heaters on this list will also save you money in the long run as their heat efficiency and power/heat control mechanisms ensure you’re not wasting anything.

It is still important to consider the whole picture and take the steps needed to get the most out of your garage’s heating, for example, proper insulation.

Nevertheless, thank you for reading this far and I hope you’ve seen a heater that is perfect for your garage. I’d like to offer warm wishes to you and your family.
