Under water circulating systems are understood heating circuits of hot water heating systems, cooling circuits, refrigerant circuits, geothermal circuits and solar circuits.

It is common nowadays to heat or cool a building via water circulating systems. As a rule, tap water is used as the basis. When using pure tap water, the problem arises that the substances contained in the water can precipitate, deposits and sludge occur in the circulatory system and also can precipitate corrosion and the resulting corrosion residues. With newly established circulatory systems, this development must already be counteracted during the filling of the circulatory systems. For this example, after the Regulation VDI 2035 Among other things, a conditioning of the circulatory system are made. This is particularly necessary because in Germany according to VDI 2035, among other things, it is possible for manufacturers of systems and components to reject warranty and warranty claims if it is not possible for the system operator to prove that conditioned water was used in compliance with the directive. This is particularly difficult to prove for private households.

The filling water passing through the ion exchanger inlet 18 in the ion exchanger 14 enters, passes through the ion exchange resin elements 30 and is thereby fully desalted / fully softened.

The water thus treated enters the ion exchanger outlet 21 off and gets to the outlet side 19 of the mixer 13 in the intersecting element 60 with a blending area 20 , Also in the blending element 60 the cableway opens 16 , At the outlet side 19 behind the blending element 60 is a lead 41 provided in which a flow meter 22 , a conductivity meter 23 and a connection 44 for another line 26 are provided.
