Solar Water Heating System

Flat Plate

Inter Solar Water Heating System works on the principle of black body absorption. The Selective Coatings used in solar collector absorbs solar radiation and convert it to Heat Energy. The hot water rises up in the risers of the collector & returns to the hot water storage tank. There is no requirement of motor or pump to circulate in thermosyphon type system however in forced system the pump is required for circulation of water.

Etc Tube

The Three super high efficiency selective coating on the inner cover of high boron and silicon content evacuated tubes absorbs the heat. When temperature rises, the density of water drops and weight goes down, hot water will go up to exchange with cold water in tank. In this way, the temperature of the water in tank goes up. ETC technology is suitable for domestic non-pressurised hot water application.
