Solar Water Heater 150 ltr Working Principle

Solar water heater is a device used to heat water by trapping sunlight in it. Solar water consists of an insulated box that is painted black from inside. The copper pipes or tubes are fitted in this box in the form of a coil. The copper’s pipes painted black from outside. The ends of the tubes are connected to the storage tank. The cold water enters the storage tank from the bottom and flows into the tubes. The sun rays fall on the heating system and get trapped inside the box. As a result water inside the tubes starts getting heat up and becomes lighter. The heavier cold water from a storage tank which is at relatively lower temperature flows down into the tubes. And the hot water that is lighter flows into the storage tank. The circulation of water continues. The process by which the water gets heated is called a thermal siphon effect thus we get hot water by trapping solar energy. Solar energy is renewable, non-polluting and abundantly available.
