(qv), were the automobile industry's first fresh-air hot water heating systems. Kelch fresh-air exhaust heaters had been available on Packard automobiles for several years prior to the introduction of these systems.
The Hupmobile system differed from the better-known Nash system by drawing up to 150 cubic feet (4.2 m³) of fresh outside air per minute through special hood louvers and thence through filters and heating coils into the passenger compartment.
