Arctic Bear HDThe Arctic Bear HD is an indirect-fired heater for extreme cold-weather conditions, such as temperatures to -60F and winds to 70 mph. All hoses and wiring are 100-percent arctic grade. Heat output ranges from 500,000 to 850,000 BTU, depending on outdoor ambient air temperature, with a maximum temperature rise of 240F. A 256-gallon diesel fuel tank gives it a run-time rating of 40 to 64 hours.
