About 80% of the sun’s radiation is turned into the heat energy needed to obtain hot water at home.
A solar water heater is a device that captures sunlight to heat water. It can be an economical way to generate hot water for your family (for shower and bath). A solar heater not only enables substantial energy savings as solar power is free in contrast to natural gas or fuel oil. Moreover, it is a way to produce hot water for sanitary use throughout the year without emitting any CO2.
The solar water heater absorbs thermal energy from sun by means of a collector placed on the roof and converts it into heat. The heat is passed onto water stored in a tank for further use. The hot water with lower density moves upwards and cold water with higher density moves down from the tank due to gravity head.

Solar water heaters do not require high maintenance.
