Meet the GHAF-400, Blu Flame's largest and most powerful self-circulating greenhouse furnace. Blu Flame's greenhouse furnaces utilize natural convection airflow that eliminates the need of any fans. This allows plants to be placed close to the heater, maximizing greenhouse space! The GHAF-400 has a BTU input of 400,000 and can heat a room up to 30' x 180', which is 5,400 sq. ft.! Choose between natural gas and liquid propane and add an optional Heat Saver Kit for increased efficiency.
Simple installation only requires a gas line, thermostat, and vent pipe - no auxiliary power required! Blu Flame's 2021 GHAF models include galvanized side and rear walls, galvanized ductwork, rear 12" elbow, and 7 - 12 x 24 pipe per unit. All models are 100% made in America with the highest quality ingredients and come with a 3-year extended warranty and 60-day satisfaction guarantee.
