So, if you:

  • Want to know how to better maintain your heating system and prolong its life;
  • Are wondering what a powerflush is;
  • Are asking yourself if your system needs a powerflush,

Then read on! This post is for you.

What is a powerflush?

A powerflush is a cleansing procedure carried out on a heating system, using a special pump. The goal is to remove dirt, sludge, debris, and rust from the water, which runs inside the pipes and radiators.

Over time, dirt and sludge build up and make the heating system inefficient. More importantly, without a powerflush every now and then, the dirty water may cause damages to your boiler.

Do I need a powerflush?

It depends on whether your system is dirty or not. If you have never had a powerflush carried out before, then you probably need it.

As an example, if you’ve had a boiler fault and British Gas has told you that you have to get a powerflush carried out before they replace any parts (usually a heat exchanger), then you’ll need to get it done.

In case you have experienced the following issues:

  • Cold radiators;
  • Dirty bleed water;
  • The boiler cutting out;
  • The boiler making noises;
  • A cold home due to blocked pipes;
  • Tepid water or temperature fluctuates;

Then it may be time to have your central heating system chemically flushed. Over time, your system will become inefficient as your boiler will struggle to heat the radiators. One way to prevent this is to do a powerflush.

Does powerflushing really work?

Powerflushing has truly proven to clean out the water and debris in heating systems. Keep in mind that if you have a boiler fault, it’s unlikely that the powerflush will fix it. However, this would be the first step to getting your boiler repaired and prevent any further damages after it’s been fixed. It is better to powerflush the system before you replace any boiler parts.

How does powerflushing increase heating efficiency

The heating efficiency is improved after a powerflush because once the system water is cleansed, the water flows easier through the pipes. The boiler needs less effort to work when the water is clean. This will increase the longevity of the entire heating system and prevent airlocks from forming in the radiators.

Why do boiler manufacturers ask you to carry a powerflush when a new boiler is installed?

The quick answer is – to maintain your boiler warranty. If a new boiler is fitted onto a system that has dirty water inside, it’s more likely to get damaged. After cleansing the system water, the boiler is protected to some degree.

Similarly, manufacturers require the boiler to be serviced annually. After all, a well-maintained boiler is less likely to fail.

Hire a professional

If you are experiencing any problems with the heating system, it’s advisable to call a professional instead of trying to find the problem yourself. If you don’t have a problem but you haven’t powerflushed your system in a long time, or at all, talk to a boiler technician, as they can help you prevent a building issue.
