The Sofpour Solar Water Heater works on 3 principles of heat transfer :
(1) Radiation (2) Conduction (3) Convection


When sunrays falls on vacuum tubes they passes through the outer transparent glass tube and hits the inner tube which is coated black with selective coating. The black colored glass tube absorbs heat and transfers it to water inside which is in direct contact with tube. The vacuum between inner and outer tube prevents heat from escaping the system. Hot water in the tube becomes lower in density and moves up towards the tank. Cold water from tank replaces hot water in the tube. This process of water circulation in called thermosyphon. Through this process, entire water of the tank gets heated up and is ready for use. The storage tank is insulated with high pressure and high density PUF insulation which minimizes the heat loss over the night and makes sure that hot water is available in the morning. Proper capacity planning can facilitate hot water consumption during day and night both.
