How To Choose a Garage Heater

Whether you’re keeping your workshop comfortable or protecting your possessions from cold nights, a garage heater can transform an otherwise unused space. But garage heaters aren’t like furnaces, so there are several things you need to consider before grabbing the first one you see.

Heat Source

Because of the items commonly found in garages such as wood or paint, it’s recommended to stick with either natural gas or electric heaters. Propane could lead to higher safety concerns, so it’s best to play it safe. Plus, these two options have some fantastic benefits.

Cost is benefit number one. Take a look at utility prices and consider how often you may be putting your garage heater to work. Natural gas can be the more cost-efficient option if you have other appliances with access.

If you don’t have access, electric may be the way to go. An electric heater is usually the least intrusive option since they can be mounted on the ceiling, creating more usable space for whatever garage occupying hobby you like to do. Make sure to check the power requirements on this one before your excitement causes you to pre-emptively buy a heater that isn’t compatible with the voltage you have in your garage.

British Thermal Units (BTU)

BTU is the energy unit used to describe how quickly the temperature can be raised in a certain space. To calculate what BTU you’ll require based on the size and ceiling height of your garage, check out this handy BTU Calculator and start talking garage-heater-talk. Generally, 50,000 BTU’s are needed to heat a 3-car garage, or a new generously sized workshop.

If you want to make it even easier, just give us a call at Crystal and we can help recommend the perfect heater for your new space.


With a heating unit, safety is always important. If your home is set up for easy access to natural gas, it’s likely you have better ventilation for a gas burning heater. This safety measure is another point in favour of these bad boys, right alongside their powerful heating capabilities. So, if you’re safely equip for a gas heater, we say go for it!

Also evaluate what’s in your garage, is it accessible to pets and children? If you’re working in a dusty space, an electric heater may be your best bet. They require minimal maintenance, unlike a gas heater which will require deeper cleaning to the air vents, motor and burner to remove any fire hazards like dust and debris. A ceiling mounted unit means the burner is further out of reach, providing more safety to innocent hands and paws.


Don’t forget to check out the detailed specs on your new heater unit before you buy. You may have thought you’ve found the perfect match until you have your heater installed and find it sounds like a jet engine taking off. You’re in the pursuit of a more comfortable environment, so consider our Modine Hot Dog Power Vented Gas Heater, equipped with “Hush-Puppy quiet operation” so you won’t be disturbed by your heater doing its work.

If you’re going to be making excessive noise anyway, or the garage is a place for your 15-year-old son’s budding rock band to practice, maybe you don’t need to worry about sound disturbance (it may even help).


Every garage is slightly different. You may have an older home with less insulation in your walls and windows or maybe a door or two that aren’t sealed properly. This will affect what your new garage heater is truly capable of. Not only that, but our fierce Canadian Winters can put garage heaters through the ringer, so make sure it’s capable of the temperature rise you’re after.

Play it safe and buy a heater with slightly more power (BTU’s) than you may deem necessary.

A heated garage is an extension of your home and can be as comfortable as your interior. If you don’t have prior experience with transforming your garage into a livable space, remember that we do.
