In consists of collector, highly insulated water storage tank & well insulated pipes circulation occurs in natural convection as water is heated in its passage through collector water from bottom of tank has higher density tends to sink. The density difference between hot & cold water provides driving force for circulation of water through collector & storage tank. After sunset a system can reverse its flow directions loss heat to environment during height to provide heat during long cloudy periods electric immersion heater can be used as back up.
