Power flush cost and benefits - what sludge does to the inside of your central heating pipesThe need for power flushing comes from a build-up of oxide sludge and calcium in the central heating system.

Sludge or calcium build up in a heating system means there could be an underlying problem that’s allowing air to get into the central heating system, causing radiators and heat exchangers to corrode.

This leaves rust and debris in the bottom of radiators which corrodes down into oxide sludge. This then leads to blocked waterways in radiators, pipe work and heat exchangers.

Blockages slow down the transfer of heat which causes pipe, valve and heating control server damage. It will, in some cases, lead to boiler replacement.

Be warned: changing your boiler without power flushing your heating system first could lead to you needing another boiler in the near future! This also applies to the controls which may have also been replaced on the system. More importantly, it will render your manufactures guarantee void.

Power Flush Cost and Benefits

How do you know if your system will benefit from a power flush? Here’s a number of symptoms to look out for:

  • Boiler switching on and off frequently (aka ‘cycling’)
  • Boiler constantly breaking down
  • If you have a combination boiler you may notice that the hot water keeps getting hot and then cold. A non-stable temperature may continue to get worse, until you do not get any hot water at all.
  • Boiler making banging and/or knocking noises
  • Central heating radiators taking a long time to heat up
  • Radiators getting cold spots
  • Radiators not getting very hot when the pipe work is getting hot
  • House always feels cold even when the heating is on
  • Boiler making ‘kettling’ noise (resembles a kettle boiling)

What happens if I don’t power flush my central heating system?

If you don’t power flush your central heating system, then your boilers can become so damaged that it will be deemed uneconomical to repair consequently, requiring a replacement.

In addition:

  • The efficiency of the system will be affected, costing you lots of money in fuel and system repair bills
  • Cause mechanical failure of pumps, motorised valves, heat exchangers and hydraulic systems in boilers
  • Pin holes will form in radiators and heat exchangers, requiring replacement or repair
  • Leaking black muddy oily oxide sludge will damage anything it comes into contact with, such as carpets, worktops and flooring

What benefits can I expect after power flushing?

Good news! There’s many benefits to power flushing your central heating:

  • Faster radiator ‘heating up’ time
  • All radiators produce more heat
  • Boiler runs quieter
  • Overall central heating system quieter
  • No cold spots on radiators
  • Cheaper gas bill – means your money stretches further
