Hello everyone,
we have just finished requesting quotes for heating, ventilation, and plumbing and received offers for various water softening systems. Among them were the BWT AQA Perla (2-tank) and a Grünbeck SoftliQ-SC18 (single-tank). What have you decided on and why? Can you recommend anything? So far, my requirement has been “softer water” below 19 degrees dH (German degrees of hardness) to reduce limescale buildup in the bathroom and washing machines and to make a decent espresso with our dual boiler. Ok, the latter could also be done with bottled water, but that’s a different topic [emoji6]
I understand that, due to the process, the sodium content of the water rises because calcium ions are exchanged for sodium ions. That’s about all I know so far. In your opinion, what else should be considered?
Thanks a lot and best regards,
Stephan

Of course, feel free to ask. We chose the SC23 because there are five of us, and it will be a two-family house. A small comfort feature is also relevant: the SC23 has a pre-alarm for the salt supply and notifies via an app. I specifically checked the size with Grünbeck directly, and they said the SC23 is designed for up to 12 people. If fewer people use it, it simply requires less salt. They should probably indicate 1-12 people in the description. Additionally, we are installing two rain shower heads, where the flow rate also matters.
Yes, the price was great. I had been monitoring it on Idealo, and when the price popped up, I went for it. It has been here since Tuesday, waiting for the exterior of the house to finally be built.

if it’s less, it simply needs less salt. You got a good salesperson there. For the regeneration of your installed system, you always need the same amount of salt per regeneration. Since the system is designed much too large, you probably won’t reach the range where your system operates economically – after 96 hours at the latest, forced regeneration takes place, and then the unused capacity until that point is lost and fully regenerated.
Choosing a larger size to run more efficiently is not possible here, especially due to salt consumption and wastewater from the larger volume.
Oh well... I don’t really care anymore, I still wouldn’t have met my required flow rates with the smaller SC18 anyway, that’s one point to consider. If you only look at the number of people, the SC18 would be running at full capacity, but it’s not just about the number of people, it’s also about the actual demand. There is a difference between having “only” 5 people in one house or 5 people spread across two houses. There are a total of 3 showers, 2 bathtubs, 2 kitchens, 2 washing machines, etc... sorry, but the SC18 wouldn’t have been able to handle that. So if it uses more salt now, that’s just how it is—because of the two separate living units, I also need more electricity, more water, more heating, basically more of everything, it can happen!
For me, this means the smaller SC18 would have been too small, and the SC23 is exactly the right size.

When regenerating your installed system, you always need the same amount of salt per regeneration.However, this is not correct, as can be seen in the data sheet. It states, quote:
So the system requires between 0.27 kg and 0.95 kg (0.6 lbs to 2.1 lbs), meaning it does not always need the same amount. Therefore, the "seller" (who was actually a technician from Grünbeck) was right with his statement.

40,000 euros is quite a hefty amount. Is anything else included, like 2 years maintenance plus salt? Otherwise, I would get some comparison quotes, just for the system and installation, that’s at least 1,000 too much.Hm, the Judo i-soft plus already costs around 3,000
Plus installation and electrical work, I’m already at 4,000.
So much for being too expensive?!

For each regeneration cycle of your installed system, you always need the same amount of salt. In ion exchangers, no more salt is reintroduced than the amount required to replace the previously bound calcium or magnesium ions. Naturally, consumption scales in some way with the system size due to technical reasons, but fundamentally your statement is not correct. And even if it were, salt is generally not a significant cost factor.
I am also curious about how the mentioned systems "without chemicals" actually work...
