Water Heating System

This system consists of collector plate, hot water tank and piping work. The collector plate absorbs the solar heat and heats water which circulates through the thin pipes placed inside the collector. Hot water temperature may go up to 65-70 degree C depending on customer requirement and solar insulation. The hot water collects in the hot water tank. Cold water line is connected to the bottom or lower side of the hot water tank and the same passes through the collector, thereby absorbing the heat. If a customer desires to have hot water in rainy season also, an electric heater may be incorporated in the hot water tank. It is very attractive to households as the payback period is 4-5 years only. Life expectancy is around 15 yrs.
