ETC Type Solar Water Heater
The Evacuated Tube Collector System facilitates high-efficiency absorption and utilisation of solar energy, with minimum heat loss.ETC Type Solar Water Heaters are made of double layer boro-silicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coated with selective absorbing material. The evacuated tubes are the absorber component in the solar water heater function. They absorb solar energy converting it into heat which is further used in water heating. This efficient use of renewable energy, provide hot water without consuming expensive electricity. Minimizes electricity bills A 100 liters capacity SWH can replace an electric geyser for residential use and saves 1500 units of electricity annually. Reduces Carbon footprint A SWH of 100 liters capacity can prevent emission of 1.5 tonnes of carbon-dioxide per year. Solar water heaters are non-polluting. Easy And Safe To Use Solar water heaters are safer than electric geysers as they are located on the roof. No scope of short circuit or electric current to anyone.
