Solar Powered Water Heater uses sunlight to heat water for domestic use, swimming pools and more and a typical direct solar thermal system consists of collector, pipes and an insulated tank. The Water Heater is available in scalable multiples of 100 large scale installations, for applications involving heat transfer can also be engineered. The Water Heater has the feature that when the sun ray fall on a solar water heater collector, made of either an evacuated vacuum tube system or flat plate collector system, the solar radiation heats up the water present in glass tubes/ metal tubes due to high transmittance of the covering glass medium. The Water Heater has the feature that the heated water, now less dense, rises in the various tubes eventually reaching the tank at the top. The Solar Powered Water Heater has an insulated tank that ensures that the hot water remains hot for a long time.
