ABSTRACT:
Tapping point including a mixer (10) for cold and hot water where the mixer (10) has a hot water inlet (20) arranged to connect to a feed pipe (64) for hot water, a cold water inlet (40) arranged to connect to a feed pipe (70) for cold water, a mixing chamber (32) for mixing hot water introduced through the hot water inlet (20) with cold water introduced through the cold water inlet (40), a space for hot water (22) between the hot water inlet and the mixing chamber (32), a space for cold water (42) between the cold water inlet (40) and the mixing chamber (32), a mixer outlet (34) for mixed water from the mixing chamber (32), and an initial valve device (30,36,50) arranged so that in an open mixing position, it allows cold water and hot water to enter into the mixing chamber (32) from their respective spaces (22,42) and exit as mixed water from the mixer outlet (34), and, in a closed mixing position, prevents the exit of mixed water from the mixer outlet (34). To impeded the growth of especially legionella bacteria within the mixer, it is among other things suggested that the mixer (10) additionally has a hot water outlet (24) from the hot water space (22) where the hot water outlet (24) is arranged so that in the closed mixing position, it is connected with a return pipe (66) for hot water via a second valve device (26), and, when in this closed mixing position, allows the circulation of hot water through the hot water space (22).
