The following lists of the best garage heater in 2022 highlights different styles of garage heaters designed to produce enough heat to make even the largest garage more comfortable during the winter. Choosing the right garage heater depends on the size of your garage, how you intend to power the heater, and whether you are looking for a portable heat source or one that is permanently installed.
