It transmits the heat generated by the burner to the water in the heating circuit.
Heat pump tank
Tank especially attuned to the heat pump.
Heat pumps use environmental energy for room heating and domestic water heating. Their functional principle corresponds to that of a refrigerator, however in the opposite direction. The refrigerant in the heat pump circuit draws heat from the earth, the air or water and vaporizes in the process.
Then it is brought to a higher pressure and thus to a higher temperature.
This "heated" steam emits heat into the heating water, whereby it liquifies again. After subsequent pressure reduction, the refrigerant is again present in its original form.

In contrast to condensing technology, here the steam is not condensed out of the flue gas.
