A heating plant, for example for a domestic water heating system, comprises a compressor 10 which is operated by an internal combustion engine 12 with a housing which is devised to accommodate a heat exchanger 28 which utilises waste heat from the engine to heat the water or other medium circulating in the system. The housing of the heat exchanger may be combined structurally with the engine cylinder head (as shown) or with another part of the engine, e.g. the crank case. The waste heat may be taken from the engine cooling water or lubricating oil. <IMAGE> |
