Function
Solar thermal collectors are used to capture energy from the sun
and efficiently transfer solar energy to heat the solar fluid in the
primary circuits of solar heating systems. This heated solar
fluid is circulated through a heat exchanger, thus heating domestic
water, which is stored in suitable tank. This heated water is then
delivered to a conventionalwater heater for final heating, if required,
or direct use.
