Solar Water heaters convert sunlight and heat from the sunlight into a heating effect. The collectors in form of vacuum tubes are responsible for absorbing the heat from sunlight and transferring it to the water inside these collectors. The heat is transferred to the tank as a result of natural heat circulation where hot water raises and cold water falls below. This heat is retained inside the tank due to the insulation around the tank.
