Low-cost Water Heater
By A. Jagadeesh, Nellore, India
A simple solar batch water heater can provide hot water for half the price of a normal solar water heater, and still keep the water warm during the night.
Mr. A. Jagadeesh of the Nayudamma Centre for Development Alternatives (NCDA) - INFORSE-member - has developed such a system. It uses two stainless steel drums, reflectors, and a cover of clear polyethylene. The cost of a 100 litre solar heater of this design is about $ 150.
