Magnetic Boiler Filters Glasgow
Protect your boiler's internal pump and narrow heat exchanger channels from abrasive black iron-oxide sludge. Installed inline on your central heating return pipe in under 2 hours.
The Science: How Black Sludge Destroys Boilers
Inside every central heating system, untreated tap water reacts with steel radiators to form black iron oxide (magnetite, Fe3O4):
Abrasive Circulation
Microscopic metallic flakes break off steel radiator panels, turning water into an abrasive liquid sandpaper circulating at high speed.
Pump Bearing Seizure
The boiler's electric circulation pump contains powerful magnetic fields that attract magnetite directly into its ceramic rotor bearings.
Heat Exchanger Blockage
Sludge bakes solid inside narrow 1mm stainless or aluminium heat exchanger fins, causing thermal stress, kettling, and crack failure.
Continuous 360° Magnetic Filtration
We install the industry-leading Adey MagnaClean Professional2. Water returning from your radiators enters a rotational swirl chamber. The centrifugal force slows water velocity while an ultra-powerful 4,000-Gauss neodymium magnet strips 100% of iron oxide particles out of circulation.
During your annual boiler service, our engineer isolates the filter valves, extracts the magnetic sheath, and washes away captured sludge in seconds without needing to drain your heating system.
Key Filtration Benefits:
- Zero restriction: Full-bore 22mm / 28mm bypass ensures zero flow rate reduction.
- Non-magnetic trap: Lower chamber collects copper filings, flux, and solder beads.
- Chemical dosing port: Integrated air vent doubles as an easy chemical dosing point.
Mandatory for Worcester, Ideal & Vaillant 10+ Year Guarantees
Boiler manufacturers now state in their warranty terms that premature failure caused by black sludge circulation will void repair claims. Fitting an inline magnetic filter unlocks maximum 10-to-12 year parts-and-labour warranty coverage.
Magnetic Filter FAQs
Common questions from Glasgow homeowners about boiler protection.
Yes. A magnetic filter can be fitted to virtually any existing gas, oil, or LPG boiler system. Our engineer drains the system partially, cuts a small section from the copper return pipe below the boiler, and fits the filter in under 2 hours.
The filter should be opened and cleaned once a year during your routine annual boiler service. In heavily sludged older systems, we recommend a secondary quick clean after the first 30 days of installation.
