  • a disadvantage of these known devices for preheating the cold industrial water in the heat exchange with the gray water, which is obtained from a hot water tap, is mainly that the usually directly connected to the greywater drain heat exchanger requires a complex construction, which is difficult to maintain and during the maintenance makes a proper use of the sampling point impossible, because the connected to the heat exchanger wastewater pipe for the gray water with a separation of the flow connection between the gray water drain and the gray water pump or the heat exchanger is no longer available for the greywater discharge.

  • the gray water stream comprising the greywater pump and the heat exchanger is connected in parallel with the conventional chen represents wastewater, which is liquid-tightly interrupted by the bottom of the greywater filter
  • simple construction conditions arise because only the usual, connected to a sewer gray water drain needs to be replaced by a housing to which the greywater pump is connected accordingly.
  • the greywater filter is to some extent a switching device that redirects greywater via the greywater pump and the heat exchanger for preheating the hot water with gray water filter used before it gets back into the sewer. If for maintenance of the heat exchanger for preheating the service water put out of action, so only the greywater filter needs to be removed from the housing in order to be able to dissipate the resulting gray water through the housing directly into the sewer.
  • the respective extraction point for the service water can thus be used without restriction even when decommissioning the greywater pump and the connected heat exchanger because the resulting gray water is discharged in a conventional manner via the gray water drain into the sewer.

If an odor trap in the form of a siphon is to be provided in the area of the waste water connection, then the waste water connection of the housing can form such a siphon, into which the gray water line of the heat exchanger discharges.
  • a separate odor trap of the sewer is not required in the form of a siphon, because by the liquid-tight completion of the sewer line through the greywater filter, an odor trap is already present, however, can no longer be effective when removing the greywater filter from the housing.
  • the greywater filter can have a pull rod rising from the floor for lifting the greywater filter out of the housing.
  • the greywater pump As long as the greywater pump is not put into operation, it represents a gray water flow obstructing flow resistance. So that a gray water backwater is prevented, the greywater pump can be controlled via a flow switch for the cold process water. If the gray water drain associated removal point for the hot water is used, the flow monitor reports the domestic water flow to the controller over which the drive for the greywater pump is turned on, which can remain switched on after closing the sampling point for a predetermined follow-up time to dissipate residual gray water to be able to.
  • a greywater line connected in parallel to the sewage line via a housing creates particularly advantageous conditions for installing a device for preheating the cold process water in heat exchange with the waste heat of the gray water, because the gray scale water pump with its drive and its control and the heat exchanger can be summarized in a separate housing, which is provided with connecting pieces for the domestic water supply and drainage and for the supply and discharge of gray water, so that the combined in this separate housing unit only these connecting pieces are connected to the housing for the gray water drain and into the
