solar water heater, device that uses solar heat energy to produce hot water. A typical solar water heater consists of a solar collector mounted on the roof of a building and connected to a water-storage tank. Depending on the system, unheated water either can be circulated from the tank through the collector to be heated directly or can be heated by a high-capacity heat-exchange fluid that was warmed in the collector and transfers its heat through tubes in the water in the tank. While heat transfer from the solar collector to the unheated water can be facilitated passively without mechanical means, “active” solar hot water systems use electricity to circulate the heat-exchange fluid and to operate mechanical pumps and controllers.
The Sun’s rays fall on the collector panel (a component of solar water heating system). A black absorbing surface (absorber) inside the collectors absorbs solar radiation and transfers the heat energy to water flowing through it. Heated water is collected in a tank which is insulated to prevent heat loss.
On average, if you install a solar water heater, your water heating bills should drop 50%–80%. Also, because the sun is free, you're protected from future fuel shortages and price hikes.
