Solar Water Heater

Solar water heaters -- sometimes called solar domestic hot water systems -- can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use -- sunshine -- is free.

Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't.


How does a solar water heater work?

A solar geyser relies on solar power, which is a source of renewable energy, to work. For a solar water heater to work it requires a set of solar collectors to absorb the solar energy. These collectors are then connected to an insulated tank that stores the hot water. When the sun is out, water is heated in the solar collectors which is then pumped or flown automatically through the thermosyphon principle to the storage tank.
