In rural India, water is normally heated on stoves fueled by wood, gas, coal and diesel. The amount of wood and fossil fuel used is enormous. Earlier, in all the accomodation facilities of BAPS, water for bathing and washing was heated by conventional means using wood, gas, coal and diesel. The Sanstha realizes the urgency of environmental protection. And that is why it has installed Solar Water Heating plants at all its major centers in India.

Solar Water Heating is the use of sunlight to heat water. The system that heats water for bathing, washing, cooking etc.. is called ‘active heating’. In active heating, mechanical means are used to store, collect, and distribute solar energy in buildings in order to provide hot water or space heating. The system can supply a home with hot water drawn from the storage tank. The storage tank allows water heated during sunny periods to be used at night or during cloudy days.
