Domestic hot water heat exchanger device for remote energy network connection has parallel valves respectively controlled by water through-flow and water temperature

摘要

The device (3) has a first valve (14) controlled by the water through-flow and a second valve (18) controlled by the water temperature for connecting the heat exchanger (1) in a domestic water supply (WW) and a heating device (2) to a remote energy network (FW), by connecting the valves in parallel with one another between the latter and the primary side of the heat exchanger.
