Hello,
my heating system has been running for just over a year now. By chance, I recently noticed discoloration on the flow meters, see picture.
I filed a defect report with the general contractor, stating that the heating water appears rusty/sludgy, as evidenced by the flow meters. Their response was a casual statement that some discoloration on the flow meters is normal to a certain extent and that if there is a serious malfunction of the underfloor heating, it will of course be fixed.
Do your flow meters look like this as well?

I had exactly the same problem. The tubes showed brown discoloration. It also happened twice that a heating circuit was blocked. Iron crystals had settled there. This was about 10 years after the heating system was installed.
I discussed all possible options with the installer.
Installing a magnet with a filter. He said, that works, buuuut: the rust has to come from somewhere. And it is usually the expansion vessel. High-quality pipes and the cheapest junk for the vessel. Stainless steel would be appropriate there. Even if a magnet and filter are installed and the water is renewed, the cause will continue to corrode until the damage fails, and then it’s really bad. First check the cause. As I said, it’s usually the expansion vessel. I didn’t pursue the matter further because I sold the apartment.

We will now hire an independent expert. However, we have to cover the costs ourselves.
