What are the signs that you need a power flush?

There are many signs that your system is suffering from a build up of what the heating industry refers to as sludge in the system 

  • Cold spots at the bottom of the radiator – sludge and dirt settles at the bottom of the radiators in little piles and as they build up the cold spots get bigger
  • The heat from the radiators is reduced
  • Radiators stay warm or cool but the pipes are hot
  • Radiators need bleeding and the water is noticeably darker than usual.
  • The system makes a banging or knocking sound, this can come from the boiler or radiators/pipes
  • Boilers overheat because they have to work extra hard to heat the home
  • Boilers can make a whistling sound as parts of it overheat or cycle on and off as the overheat stat continually cuts in
  • For combi boilers you may notice only warm water from the taps as the heat exchanger become blocked on the system side by dislodged debris

What will happen if the problems go untreated?

Leaving the problem could make it worse in many ways:

  • The system will become increasingly inefficient and expensive to run
  • The radiators will struggle to heat your home
  • Loose debris will damage parts of the boiler
  • On combination boilers, hot water will come through warm as the domestic heat exchanger blocks due to debris
  • Corrosion in the system will lead to pin holes in radiators and dirty leaks onto carpets
  • Radiators and pipework may require replacement

My boiler insurance provider says I need a power flush before they will repair my boiler

It is very common for the terms and conditions of Boiler Cover providers to state that they will not replace parts damaged by sludge until you have had a power flush. The most common repairs required are blocked heat exchanger , pump failure and valve failures none of which will be covered if there is sludge in the system.
