Frequently Asked Questions (FAQ)

What type of heater is best for a garage?

There are three main types of garage heaters you can choose from: Convection Heaters, Radiant Heaters, and Infrared Heaters. Each one works slightly differently to heat your garage and help you control the temperature.

Convection heaters blow heat into the air, roasting the contents of your garage with the heat. This can be great if you want to heat up an empty or mostly empty garage. Radiant heaters do not heat the air but instead emit infrared rays which heat objects directly. So, provided there is something in a garage to directly absorb the heat, the radiant heater will provide instant warmth. Finally, infrared heaters are both radiant and convective. They heat objects directly and the air around objects, quickly heating up an area.

How many BTU does it take to heat a 2 car garage?

The answer to this question really depends on the variables of the garage. If you live in an apartment, and your garage is attached to your home, you can count on that being heated or cooled from the rest of the house. This means you can use the heating or cooling source for the entire home as a source.

If your garage is a separate structure like an attached carport, it might need to be heated on its own. The floors and roof of an attached carport collect solar gain throughout the day, so your daytime high temperature will rise well into the 80s.

In this backyard, the garage is also a separate structure (unlike garage structures that are attached to the house), so you’ll need to estimate how much your daytime high temperature is in your area and add 10. I added 10 because I live in an area where it rarely gets under 100 degrees in the summer.

What is the most energy efficient garage heater?

For the most energy efficient garage heater, we would recommend looking at a fan heater. This kind of system is designed to replace your central heating unit entirely, so they can be quite effective. In fact, if you look at the right kind of fan heater with the right rating, you can expect it to be as effective as a central AC system.

Able to heat up a room as large as 160 square feet, these units don’t require a duct system; they can blow out the heat directly into the room through the fans. Basically, these are heaters that pump air through the fan; it’s a pretty interesting concept.

What is the best propane garage heater?

Propane-fueled garage heaters are what most people think of when they picture a traditional garage heater.

The propane-fueled ones are the almost universally preferred because they are portable and safe. You can roll them around, move then around, and store them easily. There are a few key features you’ll want to look for.

First, look for a heater with a safety shut off after it cools down. This will minimize the risk of fires.

Next, look for a heater that uses a pilot light instead of an electronic ignition. Some of the cheaper propane heaters use a small butane lighter instead of the pilot light; this results in much lower heat output.

Make sure the combustible gas line does not have any leaks or damage. This should be a relatively basic check, but it’s easy to overlook a snag in the line.
