What is a Powerflush and how do you know if you need one?

A powerflush is a way of cleaning out all the rust, sludge and debris that accumulates in your central heating system over time. By removing dirt and blockages in the pipework, you’ll extend the life of your central heating system and make sure it works more efficiently as it heats your home.

It’s not always possible to see the problems caused by the sludge in your heating system. But if you have leaking pipework, cold spots in your radiators or your boiler breaks down, then a powerflush could be the answer. The build-up of contaminated water in the system can be a major contributing factor in boiler breakdowns.

When should you get a system Powerflush?

Powerflushing is required when the system is heavily contaminated. This may be caused by many different factors including poor system design or installation, the system has not been cleaned before the installation of a new boiler or bacterial growth on low temperature systems.

It may be advised to you by the boiler manufacturers or a heating engineer that the system may require cleaning or flushing. After a water quality check has been carried out

If you’re getting a new boiler installed, you should also ensure the existing system is thoroughly cleaned before or during the installation. This will help to maintain the reliability of the new boiler, and the system components . The flush required is dependant on how dirty the existing system is. It can vary from a simple system flush with clean water to a powerful Powerflush, depending on how contaminated systems is. If the system isn’t correctly carried out, it is likely any warranties on the new boiler and other components will be void.

About Powerflushing

What happens during a Powerflush?

We use a special machine with a powerful pump which is connected to your heating system. The pump circulators a mixer of cleaning chemicals to break down any contaminates, which we then try and catch with a magnet. Once we are happy the contaminates have been displaced. We then proceed to flush the system continuously with clean water, until satisfactory TDS reading, and clarity is achieved. Once happy a system inhibitor is added to stop the system from oxidising again and help to maintain satisfactory PH levels.

How long will a powerflush take?

Most powerflush jobs will take a full day, but could take 2 days depending on the size of the system and how heavily contaminated the system is.

What areas do you cover?

We are a local plumbing and heating firm and cover Doncaster, and the surrounding area.
