I know a guy who spends an inordinate amount of time in his garage. There’s no room for a car; it’s his shop where he designs, tinkers and builds stuff. His collection of materials, nuts, bolts, screws and tools is amazing; whenever I need something, dollars to doughnuts he has what I need.
He lives in the Northwest so it gets cold and while he loves the cold, I don’t. I’m not a big fan of hanging out in cold garages so that’s where a quality garage heater comes in.
The thing with a garage heater is it needs to warm a large space and do so efficiently and safely. More specifically, it needs to be suited for the outdoors.
With hundreds of options, where do you start?
We have your back.
We filtered out a lot of the noise and put together a solid list of what we consider the best garage heaters below.
What Are the Advantages of a Garage Heater?
In most homes, the garage is not connected to the main heating system. Installing a garage heater allows you to maintain a comfortable temperature while you work in your garage.
You will be able to work comfortably late at night or to spend time in your garage during the Fall and Spring, even if the outside temperature is still chilly.
Some garage heaters are portable and can be set outside to keep your patio or other living areas warm.
How to Choose the Right Garage Heater
You should look for an appliance designed for garage or for outdoor use. An indoor space heater will not be powerful enough to keep your garage warm while remaining energy-efficient.
Look at the wattage rating and at the BTU to determine how powerful a garage heater is. You will also want a fan to circulate heat and air in your garage.
Oscillation is another interesting feature, especially if you have a large garage. A portable garage heater will be a plus if you want to be able to occasionally use it outside or would like to take this appliance with you on your next camping trip.
Should You Get an Electric or Propane Heater?
Propane is more energy-efficient. Typically, a heater can generate 91,547 BTU with a gallon of propane but would use 23KW to generate the same amount of energy.
Propane is cheaper than electricity in most cases, although it might make more sense to use an electric appliance if your local provider offers rates that are below the national average.
The main downside of getting a propane heater is that you will need to purchase propane tanks. Carrying a large propane tank can be an inconvenience and this is an additional errand you will have to run.
