A typical solar water heater is powered by the rays of the sun. A collector, often fastened on to the roof of the house, heats the water that is pumped up or driven by natural convection. The former is known as active system power heater while the latter is known as passive system water heater. There are two other types of solar water heaters with an indirect system and drain-back system that use a heat exchangers and  a controller to heat the water.

The collector is made of an insulated material with a flat solar absorber made of sheet metal attached to copper heat exchanger pipes. The water circulates to the collector panels on the roof where they are heated up and then stored into the water tank. Expensive versions of the solar water heater offer freeze protection and typically offer overheating protection as well.
