The Heatstar HS4000NG/LP Direct Fired Industrial Heater utilizes an extremely powerful fan that pulls massive amounts of cold air across the combustion chamber delivering powerful clean and reliable heat where you need it. This 400,000 BTU gas heater can be ducted up to 50ft or for maximum efficiency or can be installed in the heater space and duct the exhaust outside (Chimney kits available) therefore reheating the warm air and resulting in less heat loss over time. Unit is equipped with heavy-duty 10in pneumatic wheels and internal onboard diagnostics with a connection for an external remote thermostat. With Heatstar Heaters now you can heat the big jobs with more power, more BTUs, and more versatility.
