Most garage heaters need an electrician to hardwire them. If you already have a 240V outlet, such as a welder or dryer-style receptacle, a plug-in garage heater can be running the same day. And if you have no 240V power at all, a small propane heater needs no wiring. These three are the easiest garage heaters to set up.
We compared wattage, heat output, controls and safety features using manufacturer specifications and owner feedback; our Editorial Policy explains how we choose. For simple controls see the space heater for garage easy to use reviews. Check that your outlet matches the plug (NEMA 6-30R or 6-50R) and its breaker rating before buying. Use propane heaters only as the maker allows indoors, open a door or window slightly for fresh air, keep a working CO alarm in the garage, and never use them near gasoline or solvents.
