A garage heater takes more abuse than any heater in the house: cold starts, dust, bumps from ladders and long winter run times. The most durable models use steel cabinets, sealed or permanently lubricated motors and simple, serviceable controls. These four industrial-style unit heaters are built to last.

We compared heat output, build, controls and safety features using manufacturer specifications and owner feedback, then scored each heater out of 10; our Editorial Policy explains how we choose. For daily-use picks see the best space heater for garage for frequent use guide. Hardwired 240V heaters must be installed by a licensed electrician on the right breaker and wire size. Keep any heater at least 3 feet from gasoline, paint, solvents and sawdust, and never leave it running unattended.
