With our pre-assembled backfeed stations, you no longer have to worry about standard-compliant treatment of the make-up water in accordance with VDI 2035. The backfeed station is simply installed in the pipe system – it then ensures consistent water quality in the heating system. A change in the colour of the resin makes it easy to see when the cartridge needs to be replaced.

For small systems, we recommend our Heaty Complete Home as well as the Heaty Complete Home XL. Both products are also available without a filling combination if a system separator is already available on site.


With UWS backfeeding, you’re in the clear

Desalinated water = full use of capacity! A simple equation with our backfeeding systems, because this range enables you to achieve sustainable heating water quality with an innovative full demineralisation cartridge, which also maintains the efficiency of the system. How does it work? It’s simple! By means of controlled backfeeding, whereby an indicator cartridge shows the depletion level of the resin by changing colour, allowing you to determine the salt content of the water.
