Power Flush

Power Flush

Power Flushing is a process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so that no physical damage is caused to the system.The process can be made even more effective with the addition of powerful cleaning agents (CHEMICALS)

Are your radiators cold?

Power flushing removes these deposits and the problems that they cause….
It is prudent to power flush a heating system immediately before fitting a new boiler to an existing system to prevent possible future problems. Many systems are found to contain corrosion and sludge,even if no flow problems have yet shown themselves.

Powerflush Results
The process is carried out by trained and qualified engineers who will only finish the job when it is completed 100% with everything in great working order.

This can be achieved through persistence and correct use of equipment and we take great pride in our success in the powerflushing process. We have never failed to bring a system up to standard, functioning at a high level.

The Basics: Just what is a Powerflush

When people say ‘Power Flushing’ – they are referring to a special cleaning process that attempts to remove sludge deposits, rust and other pieces of debris from your central heating system. If these contaminants are left untreated, they can serious damage the efficiency of your heaters and, in many severe cases, a powerflush may be the only viable solution to repair it.

Over periods of time, the water that is in your radiators, pipes and boiler leaves unwanted deposits like rust, dirt and debris – creating an unpleasant muddy substance that professionals have termed ‘sludge’

When you have sludge in your heating system, it can create blockages and cause corrosion which can cause inefficiency and even breakdowns. In more extreme scenarios – it can be damaging enough that the only solution is a complete boiler replacement!

So when might you need a Powerflush?

So long as you are servicing and maintaining your system regularly (a professional service is recommended on an annually basis), then a preventative power flushing should only be necessary every 5 or 6 years – just to clean out the debris and help prevent more serious blockages from happening.

However, depending on the system that you have setup – this may vary. As an example – some boilers, instead of using stainless steel heat exchanges, use copper, which will corrode faster.

IMPORTANT: Note that if you are planning on replacing your boiler, it is essential that your engineer carries out a powerflush before the boiler installation. Not doing so could result in you contaminating your new boiler with sludge and debris that is floating around in your old pipework AND may invalidate your warranty.
