Power Flush


It’s important to keep your radiators working properly, so they can keep you warm through the winter. If you’re having problems with your heating, your radiators might need power flushing.

There are several symptoms that show you might need a power flush. If your radiators are cold at the bottom and hot at the top, you could have sludge blocking your radiators or pipes. Sludge might also be to blame if some radiators aren’t warming up while others work fine.

Having a power flush solution put through your heating system will forcibly clean it thoroughly with no damage or disruption to your system. A power Flush will eliminate any build-up of limescale or sludge in the pipes and reduce any plumbing services your many need. It will enable your plumbing system to produce better hot water and stop the radiators from only being lukewarm.

Look at our diagram below, it demonstrates some of the symptoms you may see which indicate that you may benefit from a power flush.


After installing a power flush, your boiler will be noticeably quieter and added benefits will be the money you save money on your energy bills, as the complete system will work more efficiently and at its optimum capacity. There will be minimal disruption to you and your household, reducing the number of plumbing services you may need in the future. Your existing radiators will not be removed resulting in limited mess. You could also be making a saving of up to 25% on your fuel bills.

We recommend to power flush a heating system before fitting a new boiler to an existing system to prevent possible future plumbing problems. Many systems are found to contain corrosion and sludge, even if no flow problems have yet been noticed.

Existing debris is often mobilised by alterations to the system/piping and the increased efficiency of the new boiler, and may then accumulate in the boiler heat exchanger, causing noisy operation and reduced efficiency.

At the end of the power flushing process, the system contains fresh clean water and reinstatement of the system to normal operation takes only a few minutes.
