Scalewatcher modernizes the long-established principle of magnetic water treatment with patented electronic technology.


By inducing changing magnetic and electric fields, it agitates charged particles in the water, causing minerals to form smaller, smoother crystals that are less likely to stick to pipes, heating elements, and appliances.


As new hard scale formation is prevented, flowing water gradually removes existing deposits. During this process, hardness may temporarily rise until the system is fully descaled.


How physical decalcification works.

The signal promotes the creation of many small crystals with a rotundas shape which will not easily adhere to surfaces.

Water containing charged impurities, positive and negative mineral ions and large mineral crystals with a rough surface, which easily can adhere to pipe walls.

The treatment promotes the formation of a larger number of crystals in the bulk water, which results in smaller individual crystals.
