Why Choose Professional Power Flushing?
Over time, heating systems accumulate sludge, rust, limescale, and debris. This build-up restricts water flow and forces your boiler to work harder, increasing bills and causing unnecessary strain on components.
A power flush removes all contamination, restoring full efficiency and system performance.
Common Signs You Need a Power Flush
If you’re experiencing any of the following, your heating system is likely due for a flush:
- Radiators slow to heat up
- Cold spots on radiators
- Noisy boiler or pipework
- Kettling sounds
- Radiators constantly need bleeding
- Dirty water when bleeding radiators
- High heating bills
- Poor hot water flow
- Frequent pump failures
- Boiler overheating
- Evidence of sludge in the header tank
Don’t wait until your boiler breaks down—sludge is the number one cause of central heating failures.
