The SUNFIRE Radiant Heater will provide infrared radiant heat to any industrial location up to 3,500 square feet. It provides the highest output of any portable fuel-fired radiant heater at 150000 Btu, creates a soft, low-noise sound and produces no odor or smoke. Efficient fuel use and a large 19-gallon tank provides approximately 19 hours of continuous operation. Runs on diesel, kerosene and fuel oil, but due to perfect calibration, the heater produces no carbon monoxide emissions. Made of durable steel for reliable long-term use, and the small size and flat rubber wheels allow one person to move it effortlessly. For safety reasons, the appliance is equipped with an on/off switch for quick shut-off in the event of a tip-over, as well as a built-in flame sensor that monitors the quality of the fire.
