ᐅ GRANDER Water Revitalization

Yes, yes, I know, it’s all hocus-pocus and so on. But I would still like to hear about your experiences.

I’ll tell you as a physicist: it doesn’t work.
Buy a proper water softening system.
(The salt you put in there doesn’t enter the water; it simply regenerates the ion exchanger. Just like in any standard dishwasher. Nothing else.)

This issue first came up for me in 1988. I even investigated it with one of my professors. There is no effect. No calcium ion lattice is rearranged or anything else claimed. That’s just nonsense. Because it would basically be a perpetual motion machine. The small amount of kinetic energy from the water (water has a strong dipole moment) around the magnet produces almost zero energy. Far too little to have any effect at all. Simply put, nothing happens.

PS: At least flower remedies work. Trying to soften water with magnets or persuade water not to deposit calcium in household pipes: doesn’t work.

That is not entirely correct.
In a typical drinking water softener based on an ion exchanger, which is regenerated with sodium chloride (table salt), the calcium (Ca) and magnesium (Mg) ions in the water are exchanged for sodium (Na) ions. So at least the sodium from the NaCl does actually end up in the drinking water!

Therefore, with very high water hardness levels, you cannot reduce hardness too much, because the sodium content in the drinking water must not exceed 200 mg/l (200 parts per million).

OK.

But it’s better than having a completely calcified system, broken faucets, and damaged machines.

I’m very happy: Here in Velbert, we get our water from Kettwig.
There is a small but very good water treatment plant there. For about 100 years, Velbert has been supplied through two pipelines from there, as the only other community in the Bergisches Land region. The exception is Velbert Langenberg, which gets its water from a different supplier, with quite a bit of hardness...

The water here is almost free of limescale. It has excellent quality and taste (which is why I switched to a sparkling water machine and drink tap water with carbonation).

I was able to skip installing a water softener system. After almost 2 years in the house, I haven’t even had to clean the faucet screens. Previously, just one town away (with a different water supply), I had to do that every 2 weeks. Two weeks ago, I cleaned the shower heads, but there was hardly any scale, practically none.

I grew up in an area with hard water, around 18° (°dH). Three years ago, I moved to a place with nicely soft tap water, 7° (°dH). I don’t want to go back to hard water, and since our new build has a different water supply with 19° (°dH), I purchased a Grünbeck VGX 9. However, it is still unpacked at the construction site, so I have no experience to share yet.

Tomorrow, I will ask my sister in Bavaria. I believe they also have a Grünbeck system in their home, if I’m not mistaken. The name sounds familiar to me.

I was surprised back then because the water there is extremely hard, yet there were no lime deposits anywhere. Everything was spotless. The water tasted good. Coffee and tea were very flavorful. I hadn’t experienced that before, although I lived in that region for 30 years.

That’s how we got talking about the system, and I then took a look at it in the basement. I was amazed at how simple such systems have become. Basically, they are quite straightforward.

As I said, I was very focused on such a system because beforehand, it *TOTALLY* annoyed me here as well. Kettles, boiling water twice for tea, would already have 1mm of limescale. Expensive coffee machines would fail completely after two years despite descaling. Tankless water heaters last about three years and cost $1,000 to replace. I kept faucet screens in packs of 20 in the cupboard, and so on. Water scale was a real nightmare. When I called the supplier to complain about the water quality, I was treated like I didn’t know what I was talking about. I was extremely frustrated.

But when I found out that Velbert gets its water from Kettwig, the issue was settled for me. Here, limescale is not a problem at all. I’m grateful for that.
