Solar water heater is a system in which solar energy is used to generate hot water . A solar collector that is attached with a water storage tank that is placed on the top of the building. Through this system the normal water can be heated directly by being circulated from the tank through the collector or by a high-capacity heat-exchange fluid that has been warmed in the collector and transmits its heat through tubes in the water in the tank.
HOW IT WORKS?
The sun’s solar energy heats the water in the solar collectors. Then, this water passes through a heat exchanger in the storage tank, and the heat exchanger transfers the heat to the water. The non-freezing water then cycles back to the collectors and repeats the process again and again to get warm water for use. This system is commonly used in cold places where the water is frozen in a tank.
