How Solar Water Heating Systems Work

Solar collectors, or panels, on the roof of your home are connected through a series of pipes to a solar water tank. Water pressure forces the cool water in your tank up these pipes and into the solar collectors. The collectors trap the sun’s heat and transfer it to the water inside the tank.

When the water gets hot enough from the sun, the circulation pump transfers it back into the storage tank where it rises to the top of unit. The cool water, which remains near the bottom of the unit, is pumped to the solar collectors, completing the solar heating cycle.

The circulation pump will continue to run as long as the sun is up. In times of poor weather and heavy use, a timer-controlled, back-up heating element located in the solar water tank will ensure you have hot water.
