power flushing sludge derryPower flushing is the process of removing sludge and  rust , etc.  from your central heating’s  circulation. Over a long period, these materials can  build up and lead to many other problems.

Power flushing, is flushing the central heating system under high pressure to remove all unwanted matter, such as sludge and rust. It will cleanse the central heating system and usually results in a much better performance from your system. It will improve performance , which  should cut your energy costs.. Sludge, oil, grease and rust causes the efficiency and performance to degrade, which results in notable problems such as:

  • Hot water temperature reduced over time.
  • Boiler overheats and shuts down  completely.
  • The boiler or the pump, becomes noisy or fails.
  • Certain radiators have stop working or develop hot spots. ie, only the top half is warm.
  • Your central heating system begins to take  longer periods of time to warm up.

Power flushing is especially useful for older central heating systems in which you may begin to see a reduction in performance with. It is also an excellent idea when having a new boiler installed as you will see a much better result and will avoid sludge and rust, among other materials, flowing through your new boiler. This will extend the life of your boiler ensuring you receive its maximum operational life and having to pay less for boiler repairs in the future.. We recommended you power flush your system once every 7 – 10 years.
