Descaling system: useful or not?

With current technology, you can reach 0°. However, this makes neither ecological nor economic sense. Additionally, there is a sodium limit in the [TrinkwasserV]. How much is actually possible depends on the sodium content in the raw water. Going significantly below 8° usually offers no advantages.

Is there a general rule for how low one could go with current technology, assuming, as in our case, from 23-24?

Going down to 6-8 should be no problem - check the sodium content.

you can go down as far as you want, whether it makes sense is another matter. And the higher the starting value and the more you lower it, the more salt you naturally use. I mean, we're currently at about 2 bags per year.

Hello...

we are currently also in the process of building our little home :cool:. Our water hardness is about 14dh and the house is designed for 2 people. What are the experiences with the Biocat systems? The plumber appointed by the general contractor for our house has now offered us the BIOCAT KLS 3000-C. However, I have read some online who would rather wish the system to the devil. Price-wise, this system at around €2800 + installation is also not the cheapest.

We are now wondering if such a system might be more cost-effective for us in the long run than conventional softening with salt.

What experiences have you had with these systems? What speaks in favor of the salt method, what for the catalyst technology?

It would be great if you could help me here. Alternatively, we would probably decide on a system from Grünbeck.

Thanks for your help :-)

The microplastic granulate in these systems does not soften, but causes the lime to crystallize and is therefore more of a lime protection. Such a system will definitely not change the cleaning effort. 14° would now personally not be an indication for a softening system or a "lime protection".
