Illustration of a domestic solar water heating system. Thermal energy from the sun heats fluid circulating through solar collector panels mounted on the roof (cutaway image upper left). The heated fluid passes through a heat exchanger coil in the hot water tank, heating the water. A boiler is used to heat water in the tank when there is insufficient solar energy. | |
