Our most popular garage heater, the Newair G73 is built to stand up to the toughest working conditions. Mount it on the wall or ceiling of your space to keep it safely out of the way of busy work areas. That way you can carry on with business as usual. Its powerful fan will send heat to 500 square feet of space. Because it’s a 240v, 30-amp unit, you or an electrician will need to hardwire it into a breaker. Once it’s connected, it will provide you with enough fan power to heat a two-car garage.
