inside of a garage in a private home

Whether you’re trying to protect your possessions against the cold of winter or simply keep yourself comfortable when working in the garage, an electric space heater can help. The best electric garage heater is one that is appropriately sized for the space, won’t make too much noise, and is safe to use around the whole family.

There are plenty of garage heaters on the market, but we’ve done the work to find the best options. After scouring the internet, we’ve assembled a list of the 6 best electric garage heaters to keep you warm all winter long.

How to Choose the Best Electric Garage Heater

The first step in finding the right garage heater is to measure the size of your garage. If you don’t know how much space you’re trying to heat, you won’t be able to choose the most efficient model. There are two ways to go about it. One option is to measure the length and width of your garage to get the square footage and then multiple by ten. For a 22-by-24-foot garage, you’d have about 528 square feet of space. At 10 watts per square foot, you’re looking for a 5230-watt heater.

The second option is to determine the ideal temperature for your garage and calculate the number of watts or BTUs required to achieve it. Start by calculating the volume of space you want to heat. Multiply the length of your garage by its width and height. Next, estimate your garage’s degree of insulation. If you have strong insulation, use a value of 0.5. For no insulation, us 5. If you think your garage has average insulation, use a value of 1. Finally, plug these numbers into the following formula:

Degree of Insulation x Volume x Desired Temperature Rise)/1.6 = BTU

For example, if your 22-by-24-foot garage has 8-foot ceilings, your volume is about 4,224 cubic feet. Multiply that by your average degree of insulation (we’ll use 1.5) and your desired temperature rise (we’ll use 25°). That gives you a total of 66,000 BTUs. Divide that by 3.41 to convert to watts.
