Power flushing is the process of removing sludge and rust , etc. from your central heating’s circulation. Over a long period, these materials can build up and lead to many other problems.
Power flushing, is flushing the central heating system under high pressure to remove all unwanted matter, such as sludge and rust. It will cleanse the central heating system and usually results in a much better performance from your system. It will improve performance , which should cut your energy costs.. Sludge, oil, grease and rust causes the efficiency and performance to degrade, which results in notable problems such as:
Power flushing is especially useful for older central heating systems in which you may begin to see a reduction in performance with. It is also an excellent idea when having a new boiler installed as you will see a much better result and will avoid sludge and rust, among other materials, flowing through your new boiler. This will extend the life of your boiler ensuring you receive its maximum operational life and having to pay less for boiler repairs in the future.. We recommended you power flush your system once every 7 – 10 years.
It all depends on how badly affected your heating system is. If the whole system is showing signs of bad circulation then a power flush will probably be well worth the money you pay.
Power flushing is very effective at cleaning out the system as long as it is done using a good quality machine. A power flush takes a day and costs around £450 – £750 depending on the number of radiators .
A Power flush can take up to around 8 hours to perform. On particularly complicated systems in really big houses with, it could take up to 2 days.
The tell-tale signs of sludge and/or rust build-up in your central heating system are:
The boiler is making more noise than usual
The system takes a long time to warm up
One or more radiators are cold at the bottom or top making some rooms colder than others
Radiators need regular bleeding
Sludge build-up in the feed-and-expansion tank
