What We Do

Magnacleanse System Cleaning in Trowbridge

Over 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 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.

🔍

Before

We identify cold spots, blockages and sludge build-up across every radiator

⚙️

During

We monitor heat distribution in real time to confirm sludge is being removed

After

We prove the system is clean and heating evenly — full transparency guaranteed

Thermal imaging removes all guesswork — you can see exactly what we found and what we fixed. You'll receive images as part of your written report.

Real Results

See What We Remove From Your System

These are real photos taken from a customer's central heating system in Trowbridge. The black sludge you can see is magnetite — and it was silently reducing their heating efficiency and damaging their boiler every single day.

This is what was silently damaging one customer's heating system. Without a Magnacleanse, this sludge would have continued to build up — reducing efficiency, wearing out the pump, and eventually causing boiler failure.


🚨 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)

The Process

What's Included in Our Magnacleanse Service?

  • 📷 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

Magnacleanse vs Power Flush

What's the Difference?

A traditional power flush uses high-velocity water to push sludge out of the system. A Magnacleanse uses magnetic extraction to pull sludge out — which is gentler on older pipework and highly effective at removing magnetite deposits.

We'll always assess your system first and recommend the right approach — with full, honest explanation of what's involved before any work begins.


The Savings

How Much Can It Save You?

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.

Most boiler manufacturers recommend a system clean before installing a new boiler — protecting your investment and keeping your warranty valid.
