Limescale clogs your pipes, your boiler and your appliances, and leaves marks on your taps. The good news: you can get rid of it without salt and without wasting water. Here's a SoluCalc installation we recently carried out in Forest, in the Brussels Region.
The context
Our customer wanted an effective anti-limescale solution, but without the drawbacks of a classic salt softener: salt bags to carry, regular maintenance, water wasted during regeneration and discharge to the drain. The project was carried out in Forest (Brussels).
How does SoluCalc work?
SoluCalc is a water softener that uses food-grade CO₂ instead of salt. The CO₂ neutralises limescale directly in the water: it prevents scale build-up while keeping your water 100% drinkable throughout the home. The system connects to the water inlet and runs automatically.

The benefits
- ✅ No salt: no more salt bags to carry or store.
- ✅ 100% drinkable water throughout your home, thanks to food-grade CO₂.
- ✅ No water waste and no drain connection (no regeneration).
- ✅ Virtually maintenance-free: you only need to replace the CO₂ cylinder (≈ €29/year for a family of four).
- ✅ Protects your installations: boiler, water heater, taps and appliances last longer.
Who is it for?
House or apartment, the SoluCalc is installed quickly (usually half a day) on the water inlet, provided there is a power outlet nearby. 5-year warranty.
