A fluid heating system primarily for central heating systems in which substantially all of the output energy from a combustion engine is utilised by driving a heat pump with the engine, and passing the fluid through the engine cooling system to absorb "waste" heat as well as through the heat pump, in which it absorbs heat from the atmosphere. Since a larger proportion of the "waste" output energy of a Stirling external combustion engine goes into the cooling fluid rather than the exhaust gases, this type of engine is used in the preferred forms of the invention. |
