What is a Powerflush?


Did you know that a large number of boiler breakdowns are due to dirty water and sludge building up within the boiler system? If dirt and sludge have built up within your central heating system it can have a huge effect on how well and efficiently your boiler is running.

What is a Powerflush

A power flushing unit sends water at high velocity through the system to dislodge the deposits of sludge, rust, and other debris from your central heating system. A thorough power flush will improve heat distribution throughout the property, subsequently lowering household energy bills and increasing system reliability. If left, these contaminants can seriously affect the efficiency of a heating system and in severe cases, a power flush is the only option available.

A Magnetic Chemical Flush

A magnetic chemical flush involves adding a chemical to your central heating system to break down the impurities, which are then picked up by the magnetic filters during the process. The chemical and loose debris are then drained out with the water in the piping, which is then replaced with clean water and a chemical inhibitor.

What Are the Benefits of a flush?

Here are some of the ways in which your heating system would benefit from a power flush:

  • Improves energy efficiency
  • Radiators will heat up quicker
  • Increasing lifespan of the system
  • Quieter boiler and radiators
  • Higher hot water temperatures
  • More reliable i.e. less chance of breakdown

Signs a flush is needed

Below are some of the common signs that your system may be in need of a power flush. It is best to get the advice of one of gas safe registered engineers who will be able to advise you if a power flush is required.

  • Your radiators and boiler are noisy when running
  • Leaks coming from your radiators
  • Your radiators have cold patches, particularly at the bottom
  • Your boiler keeps breaking down and needs to be restarted
  • Excessive noise from the boiler or the heating system pump
  • Your central heating takes longer than expected to warm up
  • Cloudy tap water
  • Some radiators do not heat up as well as others
  • No water escapes when you bleed a radiator


We recommend having a power flush on your whole central heating system when having a new boiler installed. Following the initial installment, a flush should be done every 5-6 years to keep your boiler running smoothly and working as you would expect.

  • Your warranty may not valid if fault is created from sludge or a blockage (Worcester Website)
