Solar water heating system is a tool that utilizes solar energy to heat water for domestic, commercial and manufacturing needs. The heating of water is the most widespread submission of solar energy in the world.
A characteristic solar water system in Uttrakhand is able to save up to 1500 units of electrical energy every year for every 100 liters per day of solar water heating aptitude.

Fractions of the Solar Water Heating System
• A solar water heater manufacturer in India consists of a flat plate solar collector, a storage space tank kept at a height following the collector, and connecting pipes.
• The collector typically comprises copper tubes welded to copper sheets (both coated with an extremely absorbing black coating) with a hard-boiled glass sheet on top and insulating substance at the back. The whole get-together is positioned in a flat box.
• In convinced models, evacuated glass tubes are used as an alternative to copper; a disconnect cover sheet and insulating box are not obligatory in this case.

Working of a solar water heater
• The commercial solar water heater is normally installed on the roof or open ground, with the collector facing the sun and allied to an unremitting water supply.
• Water flows during the tubes, absorbs solar heat and becomes hot.
• The heated water is stored in a tank for additional use.
• The water stored in the tank remains hot while sleeping as the storage tank is insulated and heat losses are minute.
Uses of solar water heater
• SWHs can be used at homes for producing hot water that can be used for bathing, clean-up, and washing. Solar water heaters (SWHs) of 100-300 litres capacity are suitable for domestic applications. Larger systems can also be used for a diversity of engineering applications. Hot water at 60-80oC could be obtained through the exercise of solar water heaters.
• Fuel Savings: A 100 litres capability SWH can return an electric geyser for housing use and saves 1500 units of electrical energy annually.
• Saves cost on power making - The use of 1000 SWHs of 100 litres capacity each can donate to a peak load saving of 1 MW.

Solar water heating has the following advantages:

Domestic Solar water heater saves electricity and thus money; electricity is becoming more and more expensive and its accessibility is becoming unreliable. Solar water heaters are non-polluting. Solar water heaters are safer than electric geysers as they are positioned on the roof.
It is the compassion of a solar water heating system. It consists of an absorber plate which is covered on its sun facing facade with an absorbent coating, also called discriminating coating. The absorber consists of a lattice of ringing tubes and sheets. Water flows during the tubes. Sheet absorbs the solar emission falling on it and shifts it to water.
