In the first one, heat exchangers are installed to protect the system from hard water obtained from bore wells or from freezing temperatures in the cold regions. In the other type, either thermosyphon or forced circulation system, the water in the system is open to the atmosphere at one point or other. The thermosyphon systems are simple and relatively inexpensive. They are suitable for domestic and small institutional systems, provided the water is treated and potable in quality. The forced circulation systems employ electrical pumps to circulate the water through collectors and storage tanks. The choice of system depends on heat requirement, weather conditions, heat transfer fluid quality, space availability, annual solar radiation, etc. The SHW systems are economical, pollution free and easy for operation in warm countries like ours. Based on the collector system, solar water heaters can be of two types. Flat Plate Collectors (FPC) based Solar Water Heaters : The solar radiation is absorbed by Flat Plate Collectors which consist of an insulated outer metallic box covered on the top with glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. The absorber absorbs the solar radiation and transfers the heat to the flowing water. There are 60 BIS approved manufacturers of Solar Flat Plate Collectors.Evacuated Tube Collectors (ETC) based Solar Water Heaters : Evacuated Tube Collector is made of double layer borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coated with selective absorbing material. This helps absorption of solar radiation and transfers the heat to the water which flows through the inner tube. There are 44 MNRE approved ETC based solar water heating suppliers. Solar water heating is now a mature technology. Wide spread utilization of solar water heaters can reduce a significant portion of the conventional energy being used for heating water in homes, factories and other commercial and institutional establishments. Internationally the market for solar water heaters has expanded significantly during the last decade. Salient Features of Solar Water Heating System : Solar Hot Water System turns cold water into hot water with the help of sun’s rays. ¾ Around 60 deg. – 80 deg. C temperature can be attained depending on solar radiation, weather conditions and solar collector system efficiency ¾ Hot water for homes, hostels, hotels, hospitals, restaurants, dairies, industries etc. ¾ Can be installed on roof-tops, building terrace and open ground where there is no shading, south orientation of collectors and over-head tank above SWH system ¾ SWH system generates hot water on clear sunny days (maximum), partially clouded (moderate) but not in rainy or heavy overcast day ¾ Only soft and potable water can be used ¾ Stainless Steel is used for small tanks whereas Mild Steel tanks with anticorrosion coating inside are used for large tanks ¾ Solar water heaters (SWHs) of 100-300 litres capacity are suited for domestic application. ¾ Larger systems can be used in restaurants, guest houses, hotels, hospitals, industries etc. Fuel Savings : A 100 litres capacity SWH can replace an electric geyser for residential use and saves 1500 units of electricity annually. Avoided uitility cost on generation The use of 1000 SWHs of 100 litres capacity each can contribute to a peak load shaving of 1 MW. Environmental benefits : A SWH of 100 litres capacity can prevent emission of 1.5 tonnes of carbondioxide per year. Life - 15-20 years Approximate cost - Rs.15000- 20,000 for a 100 litres capacity system and Rs.110-150 per installed litre for higher capacity systems Payback period - 3-4 years when electricity is replaced 4-5 years when furnace oil is replaced 5-6 years when coal is replaced Though the initial investment for a solar water heater is high compared to available conventional alternatives, the return on investment has become increasingly attractive with the increase in prices of conventional energy. The pay back period depends on the site of installation, utilization pattern and fuel replaced.

Here the solar radiation is absorbed by flat plate collectors which consist of an insulated outer metallic box covered on the top with glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water.
