In these systems, hot combustion gases in the diesel burner heat the coolant water via an air-to-water heat exchanger. A pump then circulates the hot water to either convection type radiators or more commonly, to fan-forced radiators, a type of water-to-air heat exchanger similar to the heating system in an automobile.
Where do you put a diesel heater on a boat?
Finding a location for the heater:
It should be mounted upright, higher than the fuel, placed to allow duct runs and within heater exhaust run limits. It can be mounted parallel or athwart ships. In gasoline powered boats, the heater must be located at a point higher than the engine intake manifold or carburetor.
