Abstract (en)

In order to tap bacteria-free hot domestic water at a tapping point, such as a wash basin, shower and similar point of use, in a simple manner, use is made of a method according to the invention which incorporates a heat exchanger (4), from whose secondary side the hot domestic water (18) is tapped directly and without being mixed with domestic water already heated. <??>The risk of bacteria, including the feared legionella bacteria, is eliminated hereby, since no hot water is left between the tappings, as the heating takes place only in connection with the tapping. <??>The heat exchanger (4) may be included in a water heater (1) which may be installed directly at the tapping point, thereby making the installation very compact and direct such that a high water rate and a low consumption of energy are ensured. <IMAGE>
