A solar water heater uses the sun's energy to heat water for domestic use. It typically consists of solar collectors, a storage tank, and a circulation system. The collectors, usually mounted on the roof, capture sunlight and convert it into heat. This heat is then transferred to water either directly or through a heat exchanger. The heated water is stored in an insulated tank for use in household activities such as bathing, cooking, and cleaning. Solar water heaters are environmentally friendly and can reduce energy bills.
