Power flushing, 'Hard Flushing' or 'Jet Flushing' is a process used to clean heating systems with water combined with vigorous mobilising and cleansing agents. We use a purpose-designed flushing unit with attached Magnaclean module, to prevent sludge re-entering the system.
  • The power flushing unit is attached to the heating circuit in place of a radiator, the system pump or the boiler
  • The flushing is done at high velocity, but low pressure to prevent any damage to the system
  • The heating circuit is cleansed of lime scale and corrosion debris
  • No debris remains to create blockages in the system eliminating the possibility of damage or inefficiencies had the debris been left in place.

 Power Flushing before Replacing your Boiler

Boiler manufacturers require that heating systems must be power flushed before a new boiler installation and not doing so could effect your boiler guarantee.

System Maintenance

To ensure maximum efficiency and prevent damage to your boiler you should have your central heating system power flushed at least every five years even if there are no obvious signs of problems developing.

The Importance of Power Flush

Power flushing can restore efficiency by purging your heating system of the destructive sludge that builds over time - resulting in a heating system that operates like the day it was first installed.
