Solar Water Heater System  

A Solar Water Heater is a device which provides hot water for bathing, washing, cleaning, etc. using solar energy.  It is generally installed at the terrace or where sunlight is available and heats water during day time which  is  stored  in  an  insulated  storage  tank  for  use  when  required including mornings.

At places where water is hard and have larger chlorine content, if FPC based system is being installed, it must be with heat exchanger as it will  avoid scale deposition in copper tubes of solar collectors which can block the flow of water as well reduce its thermal performance. ETC based systems will not block the flow of water but its performance may go down due to deposition of salt contents on inner surface of glass tubes, which could be cleaned easily once in a year or so
