NewAir G56 5600 Watt Garage Heater
HEATS 560 SQ FT, not the 800+ I read at first. I added the proper nema 6-30r receptacle, and wired the receptacle to an additional 240v 30amp breaker. The heater makes periodic sounds, but I have only been using for a few days. Heats up my two car garage quickly. More efficient than two 110v electric heaters that would not require this additional outlet install.
