The BILT HARD 85,000 BTU is a multi-fuel forced air torpedo heater built for job sites, barns, garages and other large unheated spaces. It burns kerosene, filtered diesel #1 and #2, fuel oil #1 and #2 and Jet A, with a 5-gallon tank the maker rates for up to 8 hours of run time. Rugged steel construction and minimal assembly make it a workhorse rather than a shop heater. Against rivals it stands out on fuel flexibility and output for its size; the trade-off is the noise and fumes typical of forced air combustion heaters, so it belongs in ventilated spaces, not living rooms.
