Description:
Heating water by virtue of freely available solar energy is still an evolving technology - at least from the consideration of further process efficiency improvements. A case in point is that of system integration, which gives the predominant benefit of making the conversion process much more efficient. This holds a competitive edge over the conventional type of solar water heating systems with separate collector and storage units. In the system under consideration, a rectangular tank of 112x80x10 cms and made of 20 gauge galvanized iron sheet has a capacity to retain about 90 liters of water. This tank painted black on the exposed side is encased in a box bearing insulation on the rear side and glass window on the exposed side. South facing orientation at a pre-determined tilt angle enables the system to function effectively. This way, the hot water is gathered from the heater outlet pipe at the top, by allowing the passage of cold water through the bottom of the collector.

Special Features:
The key feature of the above-mentioned system is its ability to offer optimum efficiency levels at some economic gain too. for example, this system heats about 90 liters of water upto 60C in winter afternoons and can also cater to early morning requirements of hot water through a proper operation and maintenance mechanism.

Prospective users
All those engaged with the production, installation and performance monitoring of solar water heaters make prospective users of this specific study
