Solar Water Heater
Solar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations is available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications. A sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (convection-driven). They use water only, or both water and a working fluid. They are heated directly or via light- concentrating mirrors. They operate independently or as hybrids with electric or gas heaters. In large-scale installations, mirrors may concentrate sunlight into a smaller collector.
- You can install the Solar Water Heater on the roof of your House.
- Solar Water Heater consists Collector and Insulated Tank.
- The Cold Water in the Collector get heated up and collected in the Tank
- The Hot Water remains Hot for 24 hours
Benefits of Solar water heater
- Saves Gas Bill
- Save Electric Bill
- Environmental Friendly (one time investment)
- 24 Hours hot water
- Low maintenance
- Hot water even when electricity is not there. (during power cuts)
Application
- Independent houses, Towers, societies
- Industrial Applications – Automobile Industry, Chemicals & Fertilizer Industry, Textiles, Pharma & Food Processing Industry etc.
- Dairies
- Hotels, Clubs & Resort and Spa’s
- Service Apartments, P.G. Accommodations, Hostels & Canteens
- Apartments, Villas & Farm House Hospitals & Nursing Homes etc.
Working principle of Solar Water Heater
Types of Solar Water Heater
Flat Plate Collector Type (FPC)
Evacuated Tube Collector Type (ETC)
Benefits Of FPC
- Capture sunlight better as they have a greater surface area exposed to the sun at any time
- Are more efficient in transferring heat – up to 163% demonstrated in Australian conditions!
- Can be used in subzero temperatures
- Are durable and if a tube should be broken, it can be easily and cheaply replaced.
- Provide excellent performance in overcast conditions
- Require a smaller roof area than comparable flat plate collectors
- Do not have the same level of corrosion problems as flat plate collectors
