Active Solar System
Active systems have solar panels on a roof or a ground rack. They are plumbed to a tank usually in the garage. A small pump circulates water from the tank through the panels thereby heating the water. The pump comes on when the water in the panels is hotter than that in the tank. When water hot water is drawn in at a faucet the incoming water forces the water from the solar tank into the standard tank and then out of the faucet. If the solar water is not enough, the standard tank will come on and heat it.
