This leads to rust and sludge of the plant. The pH value decreases particularly under sludge deposits and the heating water becomes acidic. The heat transfer is reduced and valuable energy is lost.
Floor heating pipes, valves, pumps, screw connections, ventilators or defective expansion vessels can be causes for increased oxygen in the heating system. This is one of the main causes of increased risk of corrosion.
The reaction tank of the heating water regulator HWR is equipped with a specially developed sacrificial anode. By means of a galvanic self-current, the oxygen is forced to connect with the sacrificial anode. This produces magnesium hydroxide - this brings the pH value into an optimal range. As a positive side effect, the salt content is reduced, resulting in a lower electrical conductivity.
In order to prevent deposits from clogging heating circuits / control elements and to prevent pitting, the sludge from the heating system must be filtered.
In the heating water regulator, the principle of gravity filtration is perfectly combined with a magnetic flow filter. This combination makes the system unique. This way, even the smallest sludge particles are reliably disposed of.
