Abstract:
In a water filtering and heating system for swimming pools and the like, characterised by a water pump adapted to be connected to receive water from said pool, a filter assembly connected to receive the water conveyed from said pump, and a primary heater assembly including a combustion chamber for confining the combustion of fuel, an exhaust formed above said combustion chamber for conveying the products of said combustion to the exterior, a primary heat exchanger mounted in said combustion chamber subjacent said exhaust adapted to be connected to receive said water conveyed from said filter and to return said water to said pool, the improvement comprising:a secondary heat exchanger connected to receive a part of said water conveyed from said pump and to convey said received part of said water in parallel with said filter assembly to combine with said water conveyed to said primary heat exchanger; anda mounting assembly conformed to enclose and mount said secondary heat exchanger in said exhaust, said mounting assembly including a lower pan communicating with said exhaust and conformed to support said secondary heat exchanger and a cover over said secondary heat exchanger, said lower pan and said cover being mounted over said combustion chamber in a spaced relationship relative said secondary heat exchanger to convey said products of combustion thereacross, said lower pan further defining a bounded volume for collecting the condensates of said products of combustion produced in the course of the heat exchange with said secondary heat exchanger.
