Flat plate solar water heater working principle: Flat panel solar water heater is such a kind of thermosiphon solar water heating device, which flat plate collector placed below high pressure hot water tank. The tank and flat plate are connected with two circulation pipes to form a open-loop solar water heating system,The whole system only use water, can’t use other liquid as circulation medium. By continuously circulating in this way, the water is heated directly inside flat collector and rise to be stored inside hot water tank.

Riwatt flat plate thermosyphon integrating system is composed of solar flat plate collector,
water storage tank, bracket, circulation pipe and accessories. Due to thermosyphon
principle,the collector absorbs solar energy to heat the water inside,while the thermosyphon
circulation inside enables the heated water to flow into and be stored in the water tank.
