Why you might need a power flush

To internally clean a central heating system you'll need a power flush. Water containing cleaning chemicals is flushed through the system clearing it of sludge, rust and dirt. We connect a power flushing machine to the water pipes in your central heating system. Water is then flushed through the system cleaning the inside of the pipes and radiators.

How does the dirt get into the heating system in the first place?

Central heating systems accumulate limescale, dirt, corrosion and rusting over time. The dirt comes from the inside of the radiators, pipes and boiler itself. Power flushing removes this build up from the system, thereby increasing the efficiency of the system by up to 25% and reducing your fuel bills.

Power flush

When should I get a power flush?

  • If you've had a new boiler installed (as part of the guarantee)
  • If your hot water system is slow to heat up
  • If your radiators need frequent bleeding
  • If your boiler is excessively noisy
  • If some radiators are partially or completely cold or blocked
Power Flush

Chemical cleaning your central heating system

If you have an old central heating system, it's not always a good idea to have a power flush. Pushing high pressure water through and old system can spring leaks at the joints in old pipes. So, for old systems, a chemical clean is often the better option. Chemical detergents are placed into the water and the system itself is used to create enough pressure to push the chemicals through. The entire central heating system is drained. Individual radiators that are still blocked can be removed and cleaned individually.

Power Flush

Chemical clean or a power flush?

Don't worry about it. We'll advise you on what is best for your system. Of course, we'll need to visit the property to make the corrrect assessment. But rest assured that our trained plumbers will provide you with all the information you need to make an informed decision.

TestimonialI had dead zones all over my radiators where there was no heat coming through. Multi-trade came and did a powerflush and I have to say it has worked very well. Although one radiator still has a patch on it the others are warm all over. They have done a good job. [I think we need to replace that radiator! Multi-Trade]

Laura Jenkins, London

TestimonialI had a chemical flush, as advised by your plumber and the radiators are working much better now. So, Thank-you and yes you can use this on your website.

Martha O'Connell, London

TestimonialYes, the power flush seems to have done the trick. Thanks a lot.

  • Do they have a contactable office, not just a mobile in case of any queries?
  • Does anyone answer the phone in the day?
  • Are their tradespeople honest, reliable, polite and vetted?
