Use the like. Since the device only has to be attached to a wall and connected to an existing cold water pipe.
  • the wall units according to the invention are particularly suitable for shower columns which are set up freely in a suitable room and in whose side walls one or more of the wall units are attached or installed.
  • the device is also suitable as a heat generator for underfloor heating. Due to its flat construction, the housing - which may be particularly stiff - can be arranged in a floor recess, the hot water outlet being connected at one end and the "cold water connection" at the other end of the hoses laid in the floor directly or via a pump with expansion tank .
  • a temperature limiter is arranged in the head piece carrying the heating element.
  • a z. B. mounted as a rod or tube designed longitudinal guide on which at least one bracket for a hand shower and optionally for a soap dish are height adjustable.
  • the mixer tap can have a conventional tap when the wall-mounted device is used in connection with a bathtub or another container.
  • the wall units shown contain an elongated housing 1 of rectangular cross section made of smooth aluminum profiles or plastic parts.
  • the housing 1 shown in FIG. 1 is closed at the top by a plastic cap 2.
  • an elongated cylindrical water container 3 on the bottom of which a cold water connection 4 and on the upper end of which a hot water connection 5 are fastened in a pressure-tight manner.
  • a head piece 7 is mounted, which is a holder for a three-phase heating element 8.
  • a temperature limiter 9 is mounted on the surface of the head piece 7, by means of which the current supply to the heating elements 8 is controlled.
  • the cold water connection 4 and the hot water nozzle 5 are connected via pipes 10 and 11 to a mixer tap 12, which is arranged in the lower part of the housing 1 below the water tank 3 and a hand lever for adjusting the withdrawn water quantities and the water temperature by the respective user of the shower system having.
  • the cold water line 13 is also connected to this mixer tap 12.
  • a flexible, reinforced hose 14 leads from the mixed water battery 12 to a shower 15, which in the embodiment according to FIG. 1 is fixedly mounted on a longitudinal wall of the housing 1 via a holder 16.
  • a double line 17, 18 leads to a pressure differential switch 19 arranged in the upper end part of the housing, which is housed in a protective housing 20 and blocks the cold water inlet to the liquid container 3 when the water pressure is below a predetermined value of z. B. drops 1 bar.
  • the water tank 3 and the three-phase heating element 8 form a continuous-flow heater, with a heating output of approximately 20 kW being achieved due to the design of the heating element as a three-phase unit, which leads to a heating of the with a flow temperature of approximately 10 to 14 ° C incoming cold water to a final temperature of about 45 ° is sufficient even when the maximum amount of water is withdrawn.
  • the lever of the mixer tap is opened in any "warm” position, first one phase and then the other two phases of the heating element switch on if there is a minimum pressure of 1 bar in the cold water line 13. As soon as the hot water is switched off, the heating element switches off automatically.
  • An additional switch is not provided, but may be useful for other purposes.
