When I bought my house in 2002, it was equipped with a salt water softener – I soon realized that it was flushing hundreds of liters of water down the drain every week! So I unplugged it.
Of course, I started having problems with limescale… among other things, my boiler’s internal plumbing was completely clogged!
Luckily, in 2015, I was able to benefit from CO2 technology, which is just as effective but doesn’t generate these untimely discharges to the sewer. What’s more, calcium remains present (in another chemical form) in the tap water we drink -> good for the body :). And the CO2 for one year barely costs me the equivalent of two SodaStream refills…
And there are even more little advantages – for example, I’ve identified a major water leak thanks to the Hydrokube module’s display, which shows daily consumption… 150 liters already “consumed” when I get up and nobody has taken a shower yet… not normal! With the ‘official’ hydrobru meter, I would have noticed the leak when I received my annual bill…
In short… nothing but advantages…

What’s more, we drink this water every day. The big advantage is that the water still tastes good, unlike systems with salt tablets.
Once the system is installed and properly adjusted, you forget about it and that’s that. Just check the CO2 cylinder pressure after 6 months to 1 year. The instructions provided are clear.
