Heating water comes into contact with almost all components of the system and can cause significant damage – from oxygen ingress to sludge and lime deposits, up to corrosion. Proper treatment […]

Especially in modern systems with mixed installations made of aluminum, stainless steel, steel or plastic, one thing is clear: softening alone is not enough. Because even if the water is “limescale-free”, aggressive ions such as chloride or […]
