What is the role of an anti-magnetic filter?

The main role of an anti-magnetic filter is to capture residues, especially metallic ones, circulating in the heating system, which can settle on its components. The most affected are the circulation pump and the primary and secondary heat exchangers.

Sludge, limescale, and magnetite are the most common types of residues found in the public water network, with magnetite being formed from iron oxides, metal filings, metal flakes, welding residues, and paint. These accumulate due to the passage of water through old pipes and tubes, which show signs of wear.

It is recommended that such a filter be installed on the return line of the heating system, after the last radiator and at least one meter before the water enters the heating boiler. This way, it prevents residues from entering the boiler, with the ferrous impurities being attracted to the magnet.

What are the benefits of using an anti-magnetic filter?

Due to residue deposits, heating boilers can get clogged, affecting their operation. Delaying repairs can lead to their failure, and consequently, future investments will be much higher.

Therefore, investing in such a filter is much more cost-effective than the potential repairs of the heating system.
