SOLAR WATER HEATER

Solar water heating system is a system that uses solar energy to heat water for domestic, commercial, and industrial needs. A typical solar water heating system can save up to 1400 units of electricity every year, for every 100 liters per day of solar water heating capacity. Solar water heating system consists of a solar collector, a storage tank (kept at a height behind the collector), and connecting pipes. The system is generally installed on the roof with the solar collector facing the sun and connected to a continuous water supply. Water flows through the Collector becomes hot. The heated water is stored in a tank for further use and stored water in the tank remains hot overnight as the storage tank is fully insulated.

The Evacuated Tube Collector consists of co-axial glass tubes which are fused at both ends with air between the tubes evacuated to create a vacuum that works as insulation. The outer surface of the inner tube is selectively coated to increase the absorption of solar energy. When Coldwater enters in the storage tank, fills it up and then flows into the individual tubes until all the tubes are full. When the sun rises in the morning, the heat energy is absorbed and transferred to the water in the inner tube. The heated water being lighter than the cold water rises and via the top header pipe heated water flows into the storage tank. This process continues until the temperature of the water in the storage tank and the tube equalizes. Hot water is stored in the insulated storage tank and is available for use as and when required.
