In this article, we’ll give you a step-by-step explanation of how a ‘power flush South Wales’ works. You’ll also learn about what can cause the problems that a power flush can solve. A look at our favourite flushing systems as well as guidance on how you can arrange one yourself.

Power Flush South Wales – What is a power flush?

The good thing about a power flush is that it’s reasonably self-explanatory. Using a specially designed machine that our engineers will provide; it will pump water mixed with cleaning chemicals, through your radiators at high pressure to help remove any build-up of dirt and magnetic sludge.

This is done using the following steps:

  • Upon arriving at your property, our engineer will attach the machine itself to a single entry point in your central heating system
  • That machine will then pump a powerful mix of cleaning chemicals with water throughout your system
  • As this is happening, the chemicals help dislodge and break down deposits sitting inside your radiators
  • As the process continues, it drains your system
  • Your system refills with clean water
  • Inhibitors then provide protection for your heating system against further magnetic sludge issues

All of this makes sure your boiler and heating system returns as close to its former condition. A power flush in South Wales provided by us can help prolong the life of your heating system. It helps maximise the heat output from your radiators and make sure you’re getting the best possible performance. Not only this, but it’ll also help you cut down on energy costs over time and prolong the life of your boiler (regardless of its type) as much as possible.

Why do I need a Power Flush South Wales?

While there may be several reasons for you to arrange a Power Flush, be sure to understand exactly why they’re performed. Look out for the following signs in your central heating system, and you might find you require one:

  • Radiators have cold patches near the bottom
  • Excessive ‘Kettling’ noises coming from the boiler
  • Off-colour water comes when you bleed your radiators
  • Heating generally slow to warm up
  • Hydrogen and methane gas caused by bacteria in a system can give off a strong odour in the radiators, which is noticeable whilst bleeding them. (Caution as this is flammable)
  • Excessive system noise
  • Increase in Fuel energy bills

radiator sludge build up – power flush south wales

While these are just a few of the more obvious signs to look for, it’s worth paying close attention to how everything is operating. The cause for a lot of these issues comes in the form of ‘magnetic sludge. This is an unsettling deposit that collects in your radiators and pipework.

What is magnetite sludge?

It’s a mix of rust, black iron oxide, dirt and other pieces of debris that causes blockages and ends up restricting the flow of water. Your radiators will then struggle to reach any desired temperatures. This sludge can damage your boiler, heat pump and valves, ultimately having a negative effect on your energy bills and can become costly to replace.

Magnetic sludge in your radiators can hide a multitude of things once it has built up, this is the most common cause of corrosion in radiators. From the inside of your radiators, it will cause rusting which ends up eating tiny holes in the radiator resulting in leaks.

The problem with this is if you power flush your system these holes become unblocked by the sludge and can start to leak. This can ultimately lead to you having to replace the radiators and usually the radiator valves.

It’s always best if you have a very old system to air on the side of caution.

Why do blockages like this occur?

Electrolysis, Your system contains Copper pipes, Brass radiator valves and steel radiators. As water passes through your system,  a chemical reaction occurs called electrolysis. This magnetic field strips the weakest metal. Steel radiators being the weakest erodes and forms magnetic sludge. Due to the oxygen content, this speeds up the erosion process affecting radiators before the copper pipe or brass valves.

This oil-like solution solidifies and settles in the bottom of the radiators which reduces the usable heating surface of the radiators. This can cause blockages in pipes [especially in small bore pipework ]. This process can affect the complete system and all its components.

Therefore, it can be quite easy to identify a build-up of black sludge in your radiators. If you gently run your hands over the surface, you’ll find the cold patches where it builds up (at the bottom of the radiator), making it impossible for the water to access to heat your radiator properly.

What’s the best power flushing system to use (and are there any alternatives?)

Getting a professional to do the job for you can save you a lot of hassle and money in the long run. However, you can still benefit from learning about the resources that a professional has at their disposal. Have a look at one of the best examples we like to use at BT Morgan Heating Engineers:

How much is a power flush?

There are lots of factors that will affect the price of a power flush, such as the size and complexity of the central heating system. Prices will vary from engineer to engineer but can range from £299 to £599.

Are there times when a power flush isn’t the best option?

In all honesty, yes. A power flush is certainly very good at getting the job done, and it’s clear just how much you can benefit from having one arranged for your property. However, if your property and central heating system is too old, then a slightly milder ‘Chemical flush’ might be a better option for you. You can contact a reputable heating company like us, to give you the best advice on this and in some cases, we can arrange a survey to establish the best option for you. As mentioned previously if your system and radiators are old then it does carry some risk with the condition if these radiators and any possible leaks. In some cases, it may be more beneficial to replace the system.

Who can perform a power flush?

There are power flushing kits available for hire and industrial videos available on the internet, but remember, it is a very complicated job! Hiring a professional company or a professional who has experience in power flushing systems is always the safe option. It can get very messy; specialist chemicals and equipment should only be handled by trained competent persons.
