The SUNFIRE SF80 Radiant Heater is the 80,000 BTU portable industrial-grade heater built specifically for the use case where torpedo-style heaters fall short — workshops, pole barns, garages, warehouses, and job sites where heat needs to be quiet, fume-free, and effective on extended runs. Unlike forced-air torpedo heaters that blast loud heat into wind, the SUNFIRE radiant design heats objects and surfaces directly, not subject to wind interference and quiet enough to converse near.
SUNFIRE’s signature engineering is the 99% pure fuel burn — burning diesel or kerosene cleanly enough that the work area fills with heat rather than strong odors or fumes. The 6-gallon tank delivers approximately 10 hours of continuous run time at 0.58 GPH for diesel or 0.56 GPH for kerosene, eliminating mid-day refueling for full work shifts. Coverage rated for 1,900 square feet.
Tip-over automatic shutoff promptly cuts power if the heater is accidentally knocked. Title explicitly states “USA Made” — SUNFIRE Odorless Radiant heaters manufactured in Janesville, Wisconsin. For contractors, farmers, mechanics, and tradespeople running shop heat on full-day cycles, the SF80 is the right American-made workhorse.
