Central heating power flushing [a guide]

With temperatures beginning to drop, you will want your central heating system to be prepared – particularly as you rely on it so much more in the colder months. With the ongoing energy crisis, we are becoming more conscious of our heating usage and are looking for ways to make our heating systems operate more efficiently. One of the ways you can do this is by power flushing your central heating system. This removes a build-up of sludge, rust, or debris in your boiler, pipes, or radiator and can ensure your home is heated more quickly. A power flush can be carried out by a qualified engineer and will help to reduce the cost of heating your home. Find out more about power flushing…

What is a power flush?

A central heating engineer carries out a power flush by using a powerful machine called a pumping station to send water through your central heating system at a high velocity, dislodging any grime or rust. The power flushing process involves three steps:

Step one

Once equipment is set up, it will take around 90 minutes for the engineer to flush your whole heating system. If there are any problems, such as contaminated radiators, the engineer will need to work on these separately. Special equipment may be required to dislodge an internal build-up from your radiator.

Step two

After power flushing is complete, a chemical neutraliser will be added and washed through the system. Your engineer should check the PH balance to make sure that the system is not too acidic. Excessively acidic liquid within your heating system can lead to internal damage and corrosion.

Step three

The final step is to add inhibitor fluid to the system. The purpose of this is preventing corrosion and further sludge build-up in future. Depending on the size of your heating system, a power flush should take no longer than a day to complete.

When will your central heating need a power flush?

Your central heating system may require power flushing if…

  • Your radiators are completely cold with only a hot strip at the top.
  • You notice black sludgy water in your heating system when draining/bleeding your radiator.
  • You notice your home is taking longer to warm up once the heating has been turned on.
  • If you have a magnet, check if it will attach to your copper pipes. If it does, this is a tell-tale sign that iron sludge has built up inside.

If you are considering having a new boiler fitted in your home but you have an outdated heating system and radiators throughout the property, a qualified boiler engineer can test if your current system needs power flushing before installation takes place. You may also wish to bleed your radiator as another way of improving the efficiency of your heating system, as this can improve the circulation of hot water through your pipes and radiators.
