- Vajra Plus Solar High-Performance Water Heater
High performance water heater with built-in innovation to prevent heat-loss. The Vajra Plus Solar Water Heater consists of an absorber made of capper, a storage tank with PUF insulation, piping and a transparent cover. Solar energy heats the absorber surface and heat is transferred to the water flowing through the tubes attached to the absorber. The heated water is transferred to the insulated storage tank through thermosyphon effect. A transparent glass cover is placed above the absorber to reduce heat loss through radiation and wind.
The bottom and sides of the absorber are covered with insulation to reduce both types of heat loss. The absorber, cover and insulator are placed within a metal container. Cold water flows from the bottom of the storage tank to the collector, from which heated water rises to the top of the storage tank. To maintain the functioning of the system, a constant supply of cold water must be available. For this purpose, an overhead storage tank on the roof is convenient.
