The SUNFIRE SF160 is the flagship 160,000 BTU radiant heater — the largest capacity tier in the SUNFIRE Odorless Radiant lineup, sized for large commercial shops, agricultural buildings, equipment garages, and construction sites where the SF80 and SF120 don’t have enough coverage. The 3,700 square feet coverage rating is the upper end of single-unit portable radiant heating before installations typically transition to multi-unit deployments.
The 18-gallon fuel tank delivers approximately 16 hours of continuous run time at 1.14 GPH for diesel or 1.05 GPH for kerosene — the high BTU output is balanced against tank capacity for a full-shift or overnight operation cycle without refueling. The radiant design provides the same operational advantages of the smaller SF models — quiet enough for conversation, not wind-affected, and the 99% pure fuel burn means heat without the typical fuel-heater odor.
Title explicitly states “USA Made” — SUNFIRE Odorless Radiant heaters are manufactured in Janesville, Wisconsin. Built-in tip-over automatic shutoff safety. For agricultural operations, commercial construction sites, large equipment garages, and industrial facilities running serious heating loads, the SF160 is the right SUNFIRE flagship capacity.
