A solar Water Heater is a device that helps us in heating the water by using the free and natural light energy from the Sun. The water can be heated to any desired temperature above normal temperature but cannot exceed the boiling point temperature (100° C)

Solar Water Heating System is one of the widely used solar system by which we get hot water with the help of solar radiation for domestic, industrial applications, etc. It converts Solar Energy into thermal Energy and can replace any type of conventional heating system / fuel for thermal application like water heating, air heating, etc. Solar water heating system can be classified in two types based on the collector system.

Solar water heaters based on Flat plate Collectors.

Solar water heaters based on Evacuated Tube Collectors.
