ᐅ Is a water softener system advisable or not?

I already asked some questions about our gas supplier in another thread—thanks again for the feedback.

Now we are facing the decision: "Water softener system—yes or no?"

Our house is about 10 years old (just bought it). Unfortunately, we have very hard water here (around 23). You can already see it on the faucets (where the water comes out), and of course, this isn’t ideal for cleaning or for the pipes either.

We were advised to install a water softener system (we had the idea before, too). However, the local utility company advises against it, and I have also read that these systems can be prone to bacterial growth if they are not properly maintained. Also, chemicals are said to be added to the water (I initially thought it worked through a special salt). Maintenance and service costs also seem quite high, on top of the initial purchase price.

How have you dealt with this? What do you think are the advantages and disadvantages?

At the moment, I am leaning toward not installing one.

With current technology, you can achieve 0°. However, this makes neither ecological nor economic sense. Additionally, there is a sodium limit specified in the drinking water regulations. How low you can actually go depends on the sodium content in the raw water. Generally, going significantly below 8° does not offer any benefits.

Is there a general guideline on how low you can go with current technology if you start from around 23-24 in our case?
Getting down to 6-8 should not be an issue – check the sodium content.

You can lower it as much as you want, whether it makes sense is another matter.
And the higher the starting value and the further you lower it, the more salt you will naturally use.
I think we are currently at about 2 bags per year.

Hello...

We are currently building our own small home as well 😎. Our water hardness is about 14°dH and the house is designed for 2 people. What are your experiences with Biocat systems? The plumber hired by the general contractor for our house recently offered us the BIOCAT KLS 3000-C. However, I’ve read online that some people regret having this system. The price, including installation, is around €2800 (about $3000), so it’s not the cheapest option.

We’re now wondering if such a system would be more cost-effective in the long run compared to traditional water softening with salt.

What are your experiences with these systems? What are the advantages of the salt-based method versus the catalyst technology?

It would be great if you could help me out here. Otherwise, we are likely to choose a system from Grünbeck.

Thanks for your help :-)

The microplastic granulate in these systems does not soften the water but causes the calcium to crystallize, so it acts more as a scale prevention method. Such a system will definitely not reduce the effort required for plastering.

For me personally, 14°C (57°F) would not be an indication for either a water softening system or a "scale prevention" device.
