Working of Solar Water Heaters: Solar water heaters use the Sun’s energy to heat water during the day. This water is stored inside an insulated tank for use whenever required. The Sun rays have enough energy to heat water up to 55°C to 70°C which is more than sufficient for bathing, washing clothes, use in kitchen, etc. With negligible maintenance requirement, Solar water heaters provide a low cost long term solution to getting hot water. For cloudy days, Solar water heaters have a built-in backup electric heating element. Solar water heating (SWH) is the conversion of sunlight into renewable energy for water heating using a solar thermal collector. Solar water heating systems comprise various technologies including FPC and ETC. Solar Water Heater Details: 1) ETC Solar Water Heater: i.

ETC Solar Water Heater (Evacuated Tube) Evacuated tube Collector (ETC) acts as an absorber in the solar water heater. Each evacuated tube consists of two glass tubes having vacuum in between which is an excellent insulator. The incident solar radiation falling on the tube passes through the outer transparent tube and strikes the outer of inner tube. It absorbs heat energy and then passes to the cold water flowing in the tube. An evacuated tube technology based solar water heating system is most energy efficient and cost effective. Suitable for Domestic Use. MNRE approved solar water heater with subsidy benefit. PUF insulation water tank for hot water storage upto 48 hours. Stainless Steel inner tank for longer system life. Triple layer coated vacuum tubes for higher efficiency. MS angle main parts with epoxy and PU coating. 2. ETC Solar Water Heater Features: SS-304 Food-grad Solar Inner Tank. 60mm PUF Insulation for Hot Water Tank Unique Evacuated Tube Collector. Double layer boro-silicate glass tubes. Selective absorbing coated inner tube. Design systems according to the requirement. Specially designed for hilly area. The solar radiation is absorbed by Flat Plate Collectors (FPC) 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. A Flat Plate technology based solar water heating system is most energy efficient and Long Life. Suitable for Domestic Use. MNRE approved solar water heater with subsidy benefit. PUF insulation water tank for hot water storage upto 48 hours. Stainless Steel inner tank for longer system life. Nalson Coated Copper absover for higher efficiency. MS Angle Main Parts With Epoxy and PU Coating.
