Magnacleanse & System CleanTrowbridge, Bath & Wiltshire
Remove magnetite sludge from your central heating system using the Fernox Magnacleanse process — with thermal imaging camera inspection before, during and after.
Get a Free QuoteOver time, central heating systems build up a black, muddy sludge called magnetite — a byproduct of corrosion inside your radiators and pipework. Left untreated, it can reduce your heating efficiency by up to 25%, cause cold spots on radiators, damage your pump and heat exchanger, and ultimately lead to boiler failure.
We use the Fernox Magnacleanse system — one of the most effective heating system cleaning methods available. Unlike a traditional power flush, the Magnacleanse uses powerful magnetic technology to extract sludge and debris, leaving your system running cleaner and more efficiently.
📷 Thermal Imaging Camera Inspection — Included
We're one of the few local heating engineers to use a professional FLIR thermal imaging camera as part of every Magnacleanse service. This gives you visual proof of exactly what's happening inside your heating system — before, during and after the clean.

The black sludge is magnetite — silently damaging boilers and wasting energy every single day.

This is what was silently damaging these customers' heating systems. Without a Magnacleanse, this sludge would have continued to build up — reducing efficiency, wearing out the pump, and eventually causing boiler failure. We see this every week across Trowbridge, Bath and the surrounding area.
🚨 Signs Your System Needs a Magnacleanse
- Radiators are cold at the bottom but warm at the top
- Some radiators don't heat up at all
- Your boiler is noisy — kettling, banging or rumbling sounds
- The water in your system is dark or dirty
- Your heating takes a long time to warm up
- Your energy bills have increased but usage hasn't
- Your pump or boiler keeps breaking down
- You're getting a new boiler fitted (always recommended beforehand)
- 📷 Thermal imaging inspection of all radiators before we start
- Full system assessment and water sample test
- Fernox cleaner added and circulated through the system
- Magnacleanse unit connected to extract sludge magnetically
- Each radiator individually checked and bled
- System flushed until running completely clear
- 📷 Thermal imaging check during the process to confirm results
- Fernox inhibitor added to protect against future corrosion
- Magnetic filter fitted or serviced for ongoing protection
- Full system pressure test on completion
- 📷 Final thermal imaging inspection to prove clean results
- Written report with thermal images included
A contaminated system can be up to 25% less efficient — meaning hundreds of pounds wasted on heating bills every year. After a Magnacleanse most customers notice radiators heat up faster, the home feels warmer, and the boiler runs more quietly.
