When heat is called for, domestic hot water is pumped to the heat-exchanger where the heat is transferred to the heating fluid on the other side. At the same time, the heating zone pump(s) comes on and circulates the heating fluid where it is needed.
The heating fluid is separated from the potable water supply by means of the heat exchanger. A non potable heating fluid such as anti freeze can be used.
