ABSTRACT:
A ground heating system is provided comprising an internal combustion engine which has a shaft output and an exhaust gas stream. An electric alternator/generator is driven by the shaft output of the engine. A working fluid is provided for transferring heat to the ground. A heat exchanger receives the exhaust gas from the internal combustion engine and transfers waste heat from the exhaust gas to the working fluid. An electric heating element is provided for converting some of the electric output of the generator into heat and transferring this heat to the working fluid. A pump circulates the working fluid through a ground-engaging heat exchanger.
