If you work in the garage every day, or keep it warm all winter for a car, gym or hobby, you need a heater designed for long run times. The best picks for frequent use are hardwired 240V unit heaters with steel cabinets, thermostats that cycle the heat for you and motors made for continuous duty. These four handle daily use best.
We compared heat output, build, controls and safety features using manufacturer specifications and owner feedback; our Editorial Policy explains how we choose. For the toughest builds see the space heater for garage durable reviews. 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.
