Abstract
An auxiliary or supplemental vehicle heating system that operates on natural gas or propane is provided for use with a vehicle engine having a liquid cooling/heating circuit. A propane- or natural gas-fired burner supplies heat during the operation or non-operation of the engine and the heat produced is used to supply heat to the engine, passenger compartment(s), mobile work areas, cargo containers and in the case of natural gas vehicles, provide heat to the on-board fuel system regulator. Thus, the auxiliary or supplemental heating system supplies heat independent of the engine's liquid cooling/heating circuit. In some embodiments, the cooling/heating circuit uses the heat produced from the natural gas or propane auxiliary heating system to supply heat to the engine via a heat exchanger.
