What is a powerflush?
  • Powerflushing is the most efficient and effective method of cleaning a central heating system.
  • The principle is to create a powerful fresh water flow under controlled conditions to remove debris from the system.
  • By connecting the powerflushing unit via the system pump, boiler or radiator the system can be thoroughly cleaned of limescale and corrosion debris.
When do I need to Powerflush?
So how do you know if a system needs a powerflush?

  • Are certain rooms much colder than others?
  • Does it take a long time for system to warm up?
  • Are one or more radiators cold at the bottom?
  • Do radiators need frequent bleeding?
  • Is the boiler noisy?
Boiler Noise

This increases in frequency and intensity as deposits of sludge and scale build-up in an unprotected boiler.

Radiator Cold Spots

The familiar cool, low central area of a radiator indicates a build-up of black sludge sediment that restricts flow and reduces heat output.

Pump seizure and failure

The abrasive and magnetic properties of black oxide sludge increase shaft and bearing wear in pumps causing them to stick or fail.
