Abstract:
A supplemental water heating kit for use with a hot water tank of a boat through cooperation with a coolant line for an engine of the boat, the hot water tank having a cold water inlet and a hot water outlet, the kit comprising:(A) a heat exchanger adapted to be positioned externally of the hot water tank, the heat exchanger including an exchanger water inlet and an exchange water outlet with a first flow path extending from the exchanger water inlet to the exchanger water outlet for fluid connection between the cold water inlet and the hot water outlet of the hot water tank and a coolant inlet and a coolant outlet with a second flow path extending from the coolant inlet to the coolant outlet for fluid connection with the coolant line for the engine of the boat; and (B) a water pump for connection in fluid communication between the hot water tank and the exchanger water inlet of the heat exchanger, wherein the pump circulates water from the hot water tank through the first flow path of the heat exchanger as heated engine coolant from the engine is circulated through the second flow path of the heat exchanger to effect heat transfer from the heated engine coolant to the water circulating through the first flow path.
