Our powerflushing machine

A Powerflush, as the name suggests, flushes out rust and sludge from inside your radiators, valves and pipework using chemically treated water at high velocity.  We use the latest Fernox Powerflow Powerflushing machine along with Fernox cleaning chemicals for the best results.

You May Need a Powerflush If………
  • Heating is taking a long time to get warm - poor circulation
  • Cold spots on radiators - sludge accumulating at the bottom
  • Noisy boiler and/or pump -  caused by blockages
  • Pump failure – from overworking
  • Little or no hot water - due to blocked pipes and heat exchangers
  • Blocked radiator valves
  • Signs of corrosion on radiators
  • Constant air in radiators - due to gases produced in corrosion
  • Having a new boiler - your new boiler warranty may insist on it before installation.

It is essential that any new condensing boiler is fitted to a clean system as sludge will significantly shorten the life of a modern boiler.
