Definitions

  • the invention relates to a sanitary installation with a hot water boiler and a water treatment device having a functional element, in particular for preventing limescale from being deposited.
  • the invention further relates to a connection element for a hot water boiler.

  • Suitable catalytically active, in particular granular, materials are described, for example, in international application WO 00/02658.

With such materials it is possible to catalytically precipitate lime from calcareous water or to catalytically activate the formation of the smallest lime crystals on its surface.
  • the methods and devices are installed almost exclusively in the house connection line or cold water supply line to the hot water generator.
  • Cold water treatment in the household is designed according to the peak flow (DIN 1988). Since the formation of crystallization nuclei, like any chemical reaction, follows a space-time yield, the short treatment times require large volumes in which the desired reactions for forming the crystallization nuclei can take place. For electrochemical methods, this means either large electrode surfaces or large current intensities, for catalytic methods large catalyst surfaces.
  • the storage volumes for holding the heated drinking water can now be used simultaneously to increase the average contact time in the device and thus increase the time yield while the size of the devices remains the same.

  • the devices do not have to be designed according to the peak flows of the hot water requirements, but only depend on the storage size and heating-up time of the storage, and in hydraulic terms on the delivery rate of the circulation pump.

For the same purpose it can be provided that the cover has an openable flap.
