Yes it does work if carried out properly. There are a couple of national companies. We use a Fernox powerflush 2 machine linked to a Adey powercleasne filter unit. We then recommend installing a Adey professional magna clean filter to the return pipe work to the heating boiler. Process can take upto 6hrs.

One point on power flushing, is that it can use a lot of mains water during the process.

Yes it does work. However be warned it will search out any weakness's in your system such as internal rusting in the radiators, & this can lead to leaks, just be aware of the possibility

I agree with above posts, Adding it depends on the age of the system and boiler ?

Boilers over 15 years old would better be replaced with power flush and good sytem controls. Saves much more money. Power flushing is not a miracle cure, as above said it can lead to more problems and work.

If it's done, every three years, or so, from when boiler is new, it's fairly effective. If loose sediment is left, for years, however, it will go almost as solid as lumps of concrete. Then, a power flush can't hope to be effective. It may be possible that a chemical treatment, followed a couple of weeks later by power flush, may help. As mentioned above, you need to be aware that it will tend to "find" any minor leaks, and make them worse.

It is possible (but so will corrosion) if system is to be put under higher pressure than usual. This is why you need to get advice from somebody you can trust who will properly assess the system as a whole.
