What is a Powerflush?
A powerflush is a professional cleaning of your central heating system that removes sludge, rust, and debris. Over time, your radiators and pipework accumulate magnetite sludge and corrosion, causing:
Cold spots on radiators
Slow heating systems
Noisy boilers
Frequent pump failures
High heating bills
A powerflush restores full efficiency, improves circulation, and protects your system from future corrosion.

If your system shows any of the following, a professional powerflush is recommended:
Radiator Issues
Radiators cold or unevenly heating
TRVs (thermostatic radiator valves) sticking
Boiler Problems
Boiler cuts out unexpectedly
Noisy boiler due to kettling
Components contaminated with black sludge
Other Signs
Header tank overflowing
Hot water fluctuates in combination boilers
