    Legionella are a major problem in hot water production and hot water distribution systems. For the control of Legionella It is mandatory for hot water production plants to observe temperatures above 60 ° C. Maintaining such temperatures across the entire range of hot water distribution is a considerable problem, especially for installations in larger buildings. In addition, it has been found that some of the Legionella survive even temperatures above 60 ° C for more than one hour.
    In particular, larger distribution systems for heated drinking water include one or more water distributors. From a respective water distributor go out several hot water pipes. Most such water distributors are designed in the form of rod distributors, wherein one end of a tubular portion of hot water is supplied and along the tubular portion a plurality of connecting pieces for connecting discharge lines for hot water are mounted. These bar distributors are usually installed horizontally.

    By means of the Zeltschaltelnrlchtung arranged in the purge line valve can be opened at predetermined tent intervals for a respective flushing duration. It has been found that with repeated rinsing of the water reservoir the legionella load can be substantially reduced. Belm rinsing removes contaminants from the water distributor that promote legionella proliferation. Advantageously, at least one rinsing process of the water distributor is carried out within 24 hours. The carrying out of at least one rinsing process within 12 hours is preferred, with the execution of at least one rinsing process being particularly preferred within 6 hours. The amount of withdrawn through the purge line and the wastewater hot water supplied here can be relatively low, this amount is preferably less than 10 liters, more preferably less than 5 liters, for example 2-3 liters.

As can be seen from Fig. 5, go from the water manifold 1 several hot water pipes 2, 3 from. In the hot water line 2 is a supply line through which the water distributor 1 heated drinking water is supplied. Through the hot water pipes 3 hot water can be removed from the water manifold 1. In the hot water pipes 3 5 valves 4 are shown in Fig., With which the flow through the respective hot water pipe 3 can be locked. The hot water pipes 3 lead to in Fig. 5, not shown removal points, such as taps or shower heads.
    From the water distributor 1 is further a purge line 5, as will be explained in more detail below. Hot water taken from the water distributor 1 through the flushing line 5 is fed to the sewage network (= the sewage system). In Fig. 5, a portion of a drain line 6 is shown, in which the purge line 5 opens.
    In the purge line 5, a valve 7 is arranged, with which the flow through the purge line 5 can be released or locked. The valve 7 is controlled by a timing device 8. The time switching device can open the valve 7 to release the flow through the purge line 5 and close to block the flow through the purge line 5.
    The time switching device 8 is in particular an electronic control device.
    In Fig. 5, a device for generating hot water is also shown schematically. The hot water provided by this device is fed into the hot water pipe 2. In the embodiment shown in FIG. 5, cold drinking water is supplied to produce hot water through a drinking water line 9 when the valve 10 shown in FIG. 5 is opened. The cold drinking water is passed through a heat exchanger 11 and heated therein, after which it is the hot water pipe 2 is supplied.

Second
    The wall 14 could also In the side view according to Flg. 3 be arched in the mouth region of the opening 19 to the outside, so that the container of the water distributor 1 also in this side view in the area around the mouth of the opening 19 forms a trough. Such a curvature could then extend around the entire circumference of the container 15 limiting the interior of the water distributor 1.
    The horizontal distances of all mouths of the openings 17 of hot water connections 16 from the mouth of the opening 19 of the flushing line connection 18 are at most a / 2. The horizontal distances of the mouths of the openings 17 from the mouth of the opening 19 are smaller than the height h of the interior 15 of the water distributor.
    In a central region of the interior 15, a turbulator 22 is arranged in the embodiment. It is a pipe section with a plurality of openings in the wall of the pipe section, which surrounds the central longitudinal axis of the pipe section. These are distributed in the circumferential direction and in the axial direction. At its one end, the pipe section is attached to the interior 15 limiting wall 14. At its other end, the pipe section is closed. In the interior 15 turbulences are generated in the hot water by the turbulator 22, so that no longer-term dormant areas of hot water form, if only from a portion of the water pipes 3 hot water is removed.
    The time switching device 8 is configured so that the arranged in the purge line 5 valve 7 is opened at predetermined intervals for a respective purging duration. In particular, the time intervals between successive rinses can be constant. The predetermined time intervals, after each of which a rinsing process takes place, can be adjustable on the time-switching device 8. The intervals between successive rinses are advantageously less than 24 hours, with less than 12 hours being preferred and less than 6 hours being particularly preferred. For example, a rinsing process can be carried out every two to three hours.
    In a respective flushing operation, a part of the hot water located in the interior 15 is discharged through the purge line 5 and the drain line 6 is supplied by opening the valve 7. The discharged volume of hot water is advantageously less than 10 liters, preferably less than 5 liters. For example, two to three liters can be removed per flush.
    In the rinsing contaminations that settle in the lower part of the water distributor 1, dissipated. An increase of Legionella in the water distributor 1 is thereby effectively counteracted.
    The invention is not limited to a specific type of water heating. Fig. 6 shows schematically a hot water preparation and distribution system in which the hot water distribution takes place in the manner described above, the hot water but by means of a boiler 23. In the boiler 23, for example, a heat exchanger 24 is arranged, which to a flow line 12 and return line 13 of Heating water is connected. Other types of heating for the water in the boiler 23 may be provided, for example via an electrically operated heating coil. In the hot water pipe 2, a valve 25 is arranged here.
