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.
