Wide spread utilization of ETC Solar Water Heating System can reduce a significant portion of the conventional energy being used for heating water in homes, factories and other commercial as well as institutional establishments. Internationally, the market for ETC Solar Water Heating System has expanded significantly during the last decade.
Working & Construction :
Evacuated Tube Collectors (ETC) based Solar Water Heaters
Evacuated Tube Collector (ETC) is made of triple layered borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube of this ETC Solar Water Heating System 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. ETC Solar Water Heating System is now a mature technology that is the most advanced and state-of-the-art technology in Solar Water Heaters. The efficiency of this ETC Solar Water Heating System is more than in a flat plate solar water heater. ETC Solar Water Heating Systems produce hot water even in winter / rainy days. The main part of ETC Solar Water Heating Systems is a Stainless steel PUF insulated tank and Evacuated Glass tube collectors. The vacuum tubes are with different diameter and length according to applications: in pressurized systems heat pipes are used.
