The Vaillant 28mm Filter Boiler Protection Kit is designed to protect your boiler and heating system by removing magnetite, sludge, and debris from the system water. Over time, heating systems naturally produce magnetite as metal components corrode internally, and if this debris is not removed, it can reduce system efficiency, block pipework, and damage important components such as the heat exchanger and pump.
Modern high-efficiency heating systems perform best when the system water is clean. This Vaillant magnetic filter uses advanced magnetic field booster technology to capture and remove even extremely small magnetite particles from the system. By keeping the system clean, the filter helps improve performance, maintain efficiency, and extend the lifespan of your boiler and heating components.
The filter is also designed for quick and easy maintenance, allowing collected debris to be removed in seconds without creating a mess or requiring complicated servicing.

Why Install a Magnetic Boiler Filter?
A magnetic filter is an important part of protecting a modern heating system. Sludge and magnetite can build up over time and cause reduced efficiency, cold spots in radiators, noisy systems, and potential boiler damage. Installing a magnetic filter helps capture this debris before it reaches the boiler, helping keep the system clean, efficient, and running reliably for longer.
FAQs
What is the difference between a 22mm and 28mm magnetic filter?
The difference is the pipe connection size and the boiler output they are suitable for. The 28mm version is typically used on larger systems with higher output boilers.
How does a magnetic filter work?
A magnetic filter uses a strong magnet to capture magnetite and metal debris from the heating system water before it can reach and damage the boiler.
How often should a magnetic filter be cleaned?
Most magnetic filters are cleaned during the annual boiler service, and the process usually only takes a few minutes.
