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.
