Solar hot water is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors and a fluid system to move the heat from the collector to its point of usage. Systems may use electricity for pumping the fluid, and have a reservoir or tank for heat storage and subsequent use.

Solar hot water systems are used to produce hot water for wide variety of uses, including home, business and industrial uses. Heating swimming pools, underfloor heating or energy input for space heating are more specific examples.

The evacuated tube solar hot water systems are the most efficient type.

Some advanced zero emissions systems use an electric heat pumpin conjunction with evacuated tubes. The heat pump uses a compressor to drag heat from outside air, concentrate it and transfer it to water in addition to its process heat.

Solar hot water systems with instantaneous gas boosting are also efficient, but gas is not zero emissions.
