The Essential Guide to Central Heating Power Flushing

Are your radiators not working correctly? Or do you have a noisy central heating system or boiler? If you do, the chances are that you have an accumulation of air, rust or limescale in your heating system.

It might be possible to solve these problems by bleeding your radiators. But if this does not resolve the issue, you may need a boiler engineer to power flush your pipes.

Keep reading to find out more about central heating power flushing and whether your heating system may need it.

What is a power flush?

A power flush cleans your central heating system by forcing out any debris that has accumulated in your pipes or radiators over time. This debris might consist of sludge, rust or limescale. Power flushing is normally quite efficient and can help prevent boiler faults.

When could my heating system need power flushing?

We have already mentioned a couple of occasions when your heating system might need power flushing. Power flushing might be needed if you have:

  • Radiators that warm up slowly or don’t warm up properly
  • Radiators that let out discoloured water when you bleed them
  • A noisy boiler
  • Noisy heating pipes

You could also need a system power flush if you’re fitting a new boiler. Many boiler manufacturers suggest that you flush your system before installing your new boiler and this could be a condition in the warranty.

How does power flushing work?

There are 4 stages to power flushing:

  • Firstly, your boiler engineer will attach a pump to your central heating system
  • Next, they’ll run a cleaning solution through the system to get rid of any debris
  • A rust inhibitor will then be pushed into the system to help prevent further build-up
  • Finally, your engineer will flush the system with clean water. They will check a sample of the water to ensure there is no acid left in the system

The average power flush should take between 4-6 hours to finish, but this could vary depending on the size of your central heating system and how much debris it has accumulated.

Who can perform a power flush?

Power flushing is not a DIY job. You should always hire a qualified boiler engineer to perform a power flush. When choosing an engineer, ensure you check their credentials and any online reviews they might have.
