Evacuated Tube Solar Water Heater

In an evacuated tube solar water heater, sunlight is incident on the vacuum tube, which passes through the outer transparent glass tube and strikes the outer surface of the inner glass tube coated with selective coating. The coated glass tube acts like a black body and absorbs the radiation and gets heated up in the process. The presence of vacuum between the two tubes prevents heat loss to the surroundings. This heated inner tube then transfers the heat to the water with which it is directly in contact. Thus water gets heated up. Hot water has a lower density and hence has a tendency to rise up. Cool Water from the tank comes down to replace the hot water. This sets up a circulation by Thermo-siphon. Product features: quick heat generation; can easily handle hard or soft water; storage tank is insulated using polyurethane foam (PUF) insulation; requires much lesser space due to its high efficiency; practically nil maintenance; very long life - more than 15 years; elegant appearance - made of shining glass and stainless steel; and available in various capacities. Established in 1992 as a small company, Enn Cee Enterprises has now carved a permanent place among the small group of manufacturers of solar products to cater to the global need of tailor-made products.
