There is no sediment in closed systems! – There is. The sediment is not brought into the system with water, but instead is the result of electrochemical and oxygen corrosion (due to the various metals used in the systems).

Softened or demineralised water (e.g. from a central boiler) does not create sediment! – It does. According to research carried out in the Faculty of Chemicals and Material Technology at Tallinn University of Technology, the sediment is created no matter what heat exchange medium is used.

There can be no sediment in floor heating systems with plastic pipes! – There is. The plastic pipes themselves do not corrode, but there are metals within the systems that cause corrosion (collectors, pump, heat exchanger, boiler, valves, taps, regulating valves, etc.).

A dirt separator is all you need! – It isn’t, because sediment is found everywhere in the system but the dirt separator only cleans the circulating water. Bauer's electromagnetic water treatment system cleans both the heating system and the water.
