ABSTRACT:
An improved swimming pool/spa water heating system whereby a portion of the water flow into the main heater unit (3), is preheated, thereby decreasing the time of operation of the main heater unit (3), to raise the pool water temperature to the desired temperature. The system improvement includes an arrangement wherein pool water is drawn from the pool by the water pump (22), and a portion of the water is diverted through a supplementary heater unit (27), which is located in the combustion exhaust stream of the main heating unit (3). The diverted water is thus preheated in the supplementary heater unit (27), by the residual heat in the main heater unit exhaust and is then directed back into the water system, at a point prior to the inlet of the main heater unit (3), and mixes with the remaining water in the system, thereby increasing the temperature of water into the main heater unit (3).
