Power Flush UK

Yes, a powerflush can fix cold radiators. Particularly if they are cold at the bottom.  Sludge collects in a hump in the bottom of radiators so if your radiator is cold in the middle at the bottom it can be a sign that sludge is building up.  Other places that sludge commonly builds up are in the airing cupboard and at the manifolds in microbore systems.

DIY Machine Hire

Because we are in the business of providing a professional service, we do not get many people calling to ask advice about how to do a do it themselves. It can be done though, and it can be done well IF, you are (a) a very competent DIY’er who knows how heating systems work and what can affect them, (b) you have done your homework about what metals are used in your rads and boiler, (c) you know how to quickly put right the occasional leaking compression joint without making it worse and without making a mess.

The question to ask yourself is this “Are you completely confident that you know what you are doing, that you are not going to make things worse and that you know what to do if things go wrong?” If not, you are wasting not just your time but your money hiring the kit.
