Do I need a Powerflush?

powerflush your system

A question that we get asked quite a lot, how often do you need to powerflush your system? For those who don’t know what a powerflush is, let start with the basics.

What is a Powerflush?

A Powerflush is a cleansing procedure which is carried out on your heating system using a Powerflush pump. The aim of the Powerflush is to remove dirt, sludge, debris and rust from inside the pipes of the heating system.

Why it is necessary to do this?  It’s because, over time, the dirt and sludge builds up in the system and makes the heating system inefficient.  if it is not done, the dirty water causes damage to your boiler.

Do I need a Powerflush?

This all depends on whether your system is dirty. If you have never had one carried out before and this is a new heating system, then you should probably get one carried out now to clean your system.  It may be that you have had a boiler fault and has been told you that you have to get a powerflush carried out before they will replace boiler parts.

Make a checklist on if you have these:

  • Cold radiators or dirty bleed water?
  • Boiler cuts out and makes noises?
  • A cold home due to blocked pipes?
  • Tepid water or temperature fluctuates?

If you experience any of the above symptoms it may be time to have your central heating system chemically flushed by Logical Heating & Plumbing Solutions a powerflush bromley company.

If your system is dirty and you don’t get it cleansed using a Powerflush, then you will most likely damage your boiler and your system will become ineffective as your boiler struggles to heat up the radiators.

Does Power flushes really work?

Powerflush really does clean out the system water.  If you have a boiler fault before the Powerflush is done, the Powerflush is unlikely to fix that problem.  This would be the first step to getting your boiler repaired.   It is advise to Powerflush the system before you replace boiler parts.

How does Power flushing increase heating efficiency?

Efficiency is improved after a Powerflush because, once the system water is cleansed, the water flows more easily through the pipes.  If you imagine your boiler as the heart and the pipes as the arteries, it will help to explain how it all works.  The freer the water flows around the system, the less effort for the boiler.

Why do boiler manufacturers ask for a Powerflush to be carried out when a boiler is installed?

Boiler manufacturers require that a Powerflush is carried out at the time of boiler installation in order to maintain your boiler warranty. This is because, if a new boiler is fitted onto a system which has dirty system water, there is more likelihood of damage being caused to the boiler.  In cleansing the system water, the boiler is protected to some degree.  Similarly, most manufacturers require the boiler to be serviced annually as well.  This is because a maintained boiler is less likely to fail.
