Hi!
We are looking for a water softening system that suits our needs.
The main issue is the water hardness of 44.1 degrees dH,
Sodium is at 34.5 mg/L.
Originally, we planned to use an ion exchanger because we thought the hardness was 32 degrees dH and that we would reduce it to 12, which is not ideal but acceptable for us.
However, we can only reduce it by about 20 degrees dH and still end up with 24 degrees dH, which I consider quite high.
Grünbeck has now recommended adding phosphates to bind the limescale. This would easily cost over €1/m3 for the mineral solution.
What other options are there that don’t involve gimmicks?
Carbon filter?
Reverse osmosis?
Other ideas?
And above all: how do the ongoing costs compare?
We have 3 bathrooms, expect 5–6 people living in the house, and honestly have higher water consumption. So the system must be able to handle a fairly high flow rate.
Thanks in advance for any advice on what direction to consider!

Have you ever looked at the BWT Total Energy 2500?
I don’t have experience with that one, only with ion exchangers (salt-based). With higher salt consumption, you should be able to soften the water to about 12°dH (21.6 °fH). I just checked the one from BWT, and it says it only works up to 40°dH (72 °fH). I will do some more research, thanks for the tip!
Yes, with higher salt consumption it would also work with an ion exchanger, but I still don’t want to exceed 200 mg/L of sodium. I want to be able to drink the water, and my children also like to drink bathwater while playing, so that’s not an option.
Partially not softening, but also not if I don’t want the pipes to clog quickly...

At 44.1, I would check with the supplier to see if something’s wrong. Why isn’t the water softened centrally?
Is the Calgon plant near you or what?
Is the value really correct? Location? I have no idea why it isn’t softened centrally. We live in Lower Franconia, a nice area with a lot of shell limestone in the ground...
Yes, the value is listed both on the municipality’s website and in the supplier’s analysis.

Puzzled about this water supply in portions at your place, Max.
I would lean towards a larger softening system and additionally install a reverse osmosis unit for the drinking water. The salt requirement will be significant; we have "only 24-26" and still add salt regularly.
