Abstract

See full text

A heating system is connected to a source of supply fluid to be heated, and has an internal combustion engine provided with engine coolant and gases that flow to and from the engine, and are heated thereby. A heat generator is provided in fluid communication with a supply of heat transfer fluid for circulating the heat transfer fluid in the heat generator causing fluid friction to create heat directly in the heat transfer fluid, and provide heated transfer fluid that is not in fluid communication with the engine. A fluid heat exchanger arrangement is provided in fluid communication with the supply fluid, the engine coolant, the gases of the engine and the heated transfer fluid for transferring heat from the heated engine coolant, the heated engine gases, and the heated transfer fluid to heat the supply fluid.
