• at least one riser or distribution pipe,
• a plurality of branch pipes connected to the riser or distribution pipe,
• consumer devices and flushing stations connected to the branch pipes,
• wherein the flushing stations have measuring devices for the temperature change in the branch pipe or the throughflow through the branch pipes, and/or measuring devices for the temperature change or the throughflow are provided,
• a control unit,
• wherein the control unit is connected to the measuring devices by means of data cables or by radio and receives the data about the throughflow through the branch pipes and/or risers or distribution pipes,
• the control unit has an evaluation module for the data transmitted from the flushing station, and
• the evaluation module determines, on the basis of the transmitted data, which flushing stations need to be flushed simultaneously in order for the riser or distribution pipe to be flushed.
