Here the collector is made of double layer borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coated with selective absorbing material. This helps absorption of solar radiation and transfers the heat to the water which flows through the inner tube.
Evacuated Tube Collector based Solar Water Heater : Solar water heating is now a mature technology. Wide spread utilization of solar water heaters can reduce a significant portion of the conventional energy being used for heating water in homes, factories and other commercial & institutional establishments.
Application of Solar Water Heating System:
Solar Water Heating System can heat the water up to 80C.
Solar water heaters (SWHS) of 100-500 litters capacity are suited for domestic application.
Larger systems (above 500 LPD) can be used in restaurants, canteens, guest houses, hotels, hospitals, dairies, industry etc.
