SOLAR WATER HEATER COLLECTOR

摘要

Provided is a solar water heater collector (100), which uses a non-metallic body made of a suitable grade of plastic/polymer/thermoplastic material of black color. The collector (100) absorbs heat energy from the solar radiation. The collector (100) comprises a plurality of grooves (102) for forming water paths, wherein each water path includes a riser (104) and a header. The collector (100) further comprises two layers of glass sheets (110, 112) provided above the water paths. The space between the glass sheets (110, 112) creates a vacuum to provide thermal insulation. The water gets heated through direct heating by sun rays and through heat received and retained due to the black material of the collector (100). The water inside the collector (100) is sterilized by germicidal effect of UV radiation from sun.
