SUNFIRE SF80 80,000 BTU Diesel/Kerosene Portable Radiant Heater

The SUNFIRE SF80 Radiant Heater delivers robust, reliable heat where and when you need it — from workshops, garages, warehouses and pole barns to job-site sheds, barns or outdoor-shelter areas. With 80,000 BTU/hr power output and a heating capacity up to 1,900 sq ft, SF80 drives fast, effective warmth directly to people and objects via radiant infrared heat — similar to how the sun warms, but without dust, air flow or overheating. This heater is built for real-world work environments: dual-fuel (diesel or kerosene / #2 fuel oil), a 6-gallon tank with up to 10 hours of run-time per fill, and sturdy steel construction. Its compact footprint (28″ L × 19.75″ W × 28.1″ H) and manageable dry weight (80 lb; 127 lb full) make it easy to roll or lift — ideal for flexible job-site use.

Thanks to XtremeClean technology, the SF80 operates quietly, cleanly and odor-free — no forced-air blasts, no fumes, no smell, no dust. For added control, it’s wired to accept a standard mechanical or battery-operated wall thermostat (not included), letting you maintain consistent comfort without manual adjustments. Whether you’re drying drywall, warming a workshop, thawing frozen plumbing, or keeping crews comfortable in cold weather — SF80 combines portability, power, and purity of heat in a rugged, job-ready package.
