Solar Water Heating System

Solar Water Heating Systems use the sun's thermal energy to heat water. They consist of a collector or storage tank and a circulation system. Direct systems circulate water through solar collectors where it is heated by the sun and then used directly or stored in a tank. Closed-loop, or indirect, systems circulate a non-freezing fluid to solar collectors where it is heated by the sun then passed through a heat exchanger in the storage tank, transferring the heat to the water, then cycled back to the collectors.
