The Plane System
This is a simple method that circulates the water and can be added on to almost any system. “Tee” into both cold and hot inlets close to your water heater/ tank. Cold water is drawn from low in the tank by the solar powered pump. It is passed through the panels where it is heated and returned to near the top of the tank where it is stored for use.
