Ground Heaters Arctic Bear XHD indirect-fired heater also features a stainless-steel firebox and heat exchanger and is designed to handle the coldest environments. The unit’s maximum heat output of 770,000 BTU varies with outside ambient temperature to keep the outlet temperature at a constant 210F. The heater is driven by a 240-volt, AC, three-phase generator that is, in turn, powered by a Kubota D1105 diesel engine, which is equipped with a special 20-gallon oil sump and two filters. The generator will run 3,000 hours between oil changes. The unit’s 256-gallon fuel tank allows continuous running time between 40 and 64 hours.
