SoluCalc is a salt-free water softening system that protects plumbing and appliances from limescale using CO₂. Unlike traditional salt-based water softeners, limescale is not removed from the water but converted into a soluble form that no longer builds up, even at high temperatures. The SoluCalc system is explained in detail in the video below.
Depending on your geographical region, water hardness can vary significantly and impact your household appliances and sanitary installations. Use our calculator to check the value in your municipality.
Prevents limescale buildup in pipes, faucets, and fixtures, extending their lifespan significantly.
Your boiler heats water 25% more efficiently without limescale, reducing energy bills dramatically.
No more scrubbing limescale stains. Surfaces stay cleaner longer with less effort and chemicals.
Washing machines, dishwashers, and water heaters last years longer without scale damage.
Uses only food-grade CO₂ - no salt, no waste, no environmental impact.
Keeps beneficial minerals while eliminating scale problems - healthier for you and your family.
"Solucalc makes watersofteners based on CO2 instead of salt, and I have to say that this works very good. We used the water 5 days without CO2 because the bottle finished, and my god, we had a lot of hard water 'damage' immediately. So very happy with this easy solution that saves space. We had a very good contact with the sales guy and also during installation everything went super smooth."
"This system is a good alternative if you live in an apartment without the possibility of installing a salt water softener in the basement, as in my case. It works :)"
Leading companies like IKEA, Aqualibi, Decathlon, and Brussels Airport trust SoluCalc for their limescale prevention solutions
