– Water circuit between the panels and serpentine the water tank;
– Water circuit between the boiler and the second serpentine of the water tank.
In this way regulate heat exchange therebetween.
It is possible to include a third pump to regulate the heat exchange between the solar panels and a second tank (buffer tank or pool).
