Water inside the heating system contains organic substances (such as bacteria and algae) and inorganic substances (such as sand, rust, welding residues). In addition to these deposits there are limescale encrustations (calcium and magnesium precipitations, hardness salts) that contribute to obstructing the passages and are responsible for triggering corrosive phenomena. Corrosion is in general a process that is characterized by the superficial removal of metal, more or less deep, which can also lead to the pipe perforation.
