Solar Water Heater
working principle:
The system
consists of flat plate solar collector and highly insulated water tank. The
collector is designed such that the cold water entering is heated up when
sunshine falls on it. The heated hot water moves up and stored in the
insulated water tank due to the decrease of density, the fresh water
reaches the solar collector by thermosyphoning
(Natural Flow). This process carries automatically till the sunshine is
available. The hot water stored in the tank will have a
heat retention for three days.
