Working Principle of ETC V-Guard Solar Water Heater

When the sunlight incident on the vacuum tube passes through the outer transparent glass tube and strike the outer surface of the inner glass tube with selective coating. This glass tube, which acts like a black body, absorbs the radiation and gets heated up in the process. The presence of vacuum between the two tubes prevents heat loss to the surroundings. The heated inner tube transfers this heat to the water with which it is directly in contact.  The density of hot water is lower and therefor it has a tendency to rise up. The cold water from the tank flows down to replace the hot water, facilitating circulation by Thermosiphon. Through this process the entire water in the tank heats up and gets ready for the use. The storage tank is insulated with PUF which minimize the loss at night.
