Self-contained flameless fluid heating system

A heating system comprising:

• an internal combustion engine provided with engine coolant and gases and configured to heat the engine coolant and the gases during operation of the engine to provide heated engine coolant and heated engine gases;
• a supply source providing a supply fluid in fluid communication with a supply fluid inlet;
• a supply fluid outlet in fluid communication with the supply fluid inlet and the supply source;
• a fluid heat exchanger arrangement being in fluid communication with the supply fluid of the supply source and the engine coolant and the gases of the engine and configured for receiving heated engine coolant and heated engine gases, and configured for transferring heat from the heated engine coolant and the heated engine gases to the supply fluid to heat the supply fluid;
• a heat generator in fluid communication with a heat transfer fluid reservoir containing a heat transfer fluid, the heat transfer fluid circulating within the heat generator to create fluid friction therein to heat the transfer fluid and provide heated transfer fluid;
• a heat transfer fluid heat exchanger in fluid communication with the heat generator and the supply fluid for receiving the heated transfer fluid from the heat generator, and configured for transferring heat from the heated transfer fluid to the supply fluid to further provide heated supply fluid;
