A heating system for heating at least one of a fluid-filled conduit arrangement and a volume of air includes an internal combustion engine provided with engine coolant that flows to and from the engine and is heated thereby. A fluid heat exchanger is provided in fluid communication with a heat transfer fluid stored in a reservoir and the engine coolant of the internal combustion engine. The fluid heat exchanger receives heated engine coolant from the internal combustion engine, and transfers heat from the heated engine coolant to the heat transfer fluid to provide heated transfer fluid. A heat generator is provided in fluid communication with the fluid heat exchanger, and receives the heated transfer fluid from the fluid heat exchanger for further heating. This heated transfer fluid may then be selectively used to heat a conduit or a volume of air.
