An internal combustion engine has a reservoir containing oil which is circulated through passageways in the engine by an oil pump to lubricate and cool the engine. A tube has a spiral portion located in the reservoir and a cooling liquid, preferably water, is pumped through the tube to cool the heated oil in the reservoir. The water is thus heated and subsequently enters and discharges this heat in a heat receiver which is preferably part of a home-heating system. In a preferred embodiment, the heating system includes a heat pump which is operatively coupled to the heat receiver, the compressor of the heat pump being driven by the engine. In another preferred embodiment, a portion of the engine exhaust pipe extends through the reservoir so that heat from the gases passing through the pipe is at least partially transferred to the oil in the reservoir. |
