Magnetic Filter Service

What this service covers

A magnetic filter sits on your heating pipework and traps iron oxide sludge before it circulates around the system. Servicing it helps your system run more reliably and can prevent avoidable wear.

Typical coverage includes:

• Inspection of the magnetic filter and surrounding valves and pipework
• Safe isolation of the filter to minimise water loss
• Removal and cleaning of the magnet and filter chamber
• Clearing collected sludge and debris and checking for signs of ongoing contamination
• Resealing, refitting and checking for leaks
• Basic system checks to confirm good circulation and normal operation

When a magnetic filter service is most useful

This service is particularly relevant if:

• Radiators have cold spots or take longer to heat up
• You have noisy pipework, pumps or valves
• The boiler has shown low flow or blockage related fault codes
• The filter has not been cleaned since installation
• You have had recent system work and want to keep the pipework clean

What happens during the visit

The heating is made safe to work on and the filter is isolated. The magnet and filter body are cleaned thoroughly, then the unit is reassembled, brought back into service and checked for leaks. Where appropriate, you will be advised if further steps are sensible, such as a deeper clean of the system or topping up inhibitor.

After the service: keeping the system clean

A clean filter is only effective if it is maintained. You will get clear guidance on when the next clean is likely to be due and what warning signs to watch for, so performance issues can be addressed early rather than after a breakdown.
