A gasoline heater is a small gasoline-fueled space-heater. Fixed versions were originally used mainly for supplemental heat for passenger compartments of automobiles and aircraft, with the latter still in production. Portable versions were also made.
Gasoline heaters were commercially available on automobiles starting in the 1930s with continued use until the 1960s, when they were almost entirely replaced with heaters that blow air past a small radiator warmed by hot engine coolant.
