ABSTRACT:
An apparatus for heating a domestic water supply including a glass-lined storage tank to contain the domestic water supply. A combustible fuel burner is positioned to heat the domestic water supply within the glass-lined storage tank. A solar heating tube is connected to supply solar heated fluid to a heat transfer coil mounted within the glass-lined storage tank. The heat transfer coil has a double-wall including a non-metallic outer wall in contact with a metallic inner wall, both walls being sealed to prevent mixing of the domestic water supply with the solar heated fluid. A sensor is positioned to sense the temperature of the solar heated fluid as it is delivered to the heat transfer coil. A controller is connected to the temperature sensor and to the combustible fuel burner to actuate the burner to heat the domestic water supply when the temperature of the solar heated fluid is insufficient to heat the domestic water supply by heat transfer from the solar heated fluid in the heat transfer coil to the domestic water supply in the glass-lined storage tank.
