In order to provide for a quick heating up of water in a container independently of its volume, a heat exchanger device comprises a container having a water inlet in a bottom section and a water outlet in an upper section as well as a heat transfer tube menas for conducting a heating fluid through said container. The heat transfer tube menas enter said container in said upper section and extend to a lower section so as to heat up the water in the upper section first.
