Power Flushing And De-scaling For Homes And Commercial Properties
Last Updated: 5 April 2017. Bob Jones (pictured right) knows how to solve your heating and hot water problems. He did his first “power flush” in 1992 when hardly anyone in the plumbing and heating world had heard of it and in 2004 set up Powerflush UK to provide the first nationwide power flushing service for domestic and commercial heating systems.
Since 2004 we have carried out over 3000 successful powerflushes in systems of all types and sizes.
PowerFlushUK will give your system a thorough inspection and after an efficient and effective procedure will provide you with:
- Visual and written evidence of the state of your system
- A certificate proving and guaranteeing the ‘inner cleanliness’ of your system.
- We will do the work when it suits you and we promise to leave your house how we found it. (But better!)
- A guarantee against blockages in your system for five years
- All of this for a competitive package price from £340 for a typical 3 bedroom house. (This is often up to half the cost of power flushing by a well known national energy supplier!)

What is powerflushing?
Powerflushing is purely and simply a way of removing the rust that slowly builds up in your heating system and boiler over time. Water, chemicals, powerflush equipment and an experienced plumber are used to remove the rust and sludge from your central heating.
Where does the rust in my heating system come from?
If you have seen someone else’s system powerflushed you will know what an amazing amount of stuff can come out, in all shapes and sizes. But, contrary to popular belief the vast majority of the sludge that you see does not come from your boiler. Most non-condensing boilers (those installed before 2006) have cast-iron heat exchangers and they, by and large, do not rust. The vast majority or rust and/or sludge in your heating comes from the radiators themselves as they are made from mild-steel.
Why does rust form in the first place?
Water is made of hydrogen and oxygen (one part H and two parts O = H2O). Oxygen is highly reactive and is always looking for somewhere to latch on to instead of the Hydrogen molecule. So, any time it comes across a piece of iron that is ‘bare’, i.e. unprotected, it is going to latch on to that and makes rust (most often Fe2O3). And that’s where rust comes from. Power flushing radiators will remove that.
How do I protect my heating system after it is cleaned?
Once you have had a specialist in to do the work for you, the best way of protecting your system is to have the heating system regularly topped upped with corrosion inhibitor. These stop the rust forming by adding a protective molecule to any exposed bare iron. That molecule (most often a form of another metal called molybdenum) parks in the place that the oxygen molecule would want to be. And the result is no rust. The only caveat to this is if your heating system has a design flaw in it and is pulling in fresh water all the time.
Do I need to Powerflush, or , is there another way of cleaning the radiators?
Yes, there are other ways, but they are nowhere near as effective as using a the right machine when it is used by a competent and experienced heating engineer. You can add any chemical cleaner in to the system, leave for up to four weeks (Warning:careful here if you have micro-bore pipework) and then open up the system drain-cocks and let the water run out.
When you do that the only force moving the water out of the system is gravity and that will not pick up any larger bits of rust. Those will be left in nooks and crannies.
This article from the original designer-makers of power flushing equipment explains in more detail why using an expert with the right kit is usually a good idea.
DIY Machine Hire
Because we are in the business of providing a professional Powerflush service, we do not get many people calling to ask advice about how to do a do it themselves. It can be done, 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.
Can micro-bore pipework be powerflushed?
The short answer is “Yes, it can”, but with a great deal of care. Microbore systems need to be approached in a very different way to standard sized pipework. Microbore pipework was first commonly introduced in the 1970’s in an attempt to reduce the amount of copper needed to install a heating system.
The first thing you need to find out is if your system actually has microbore pipework. If you don’t know, a generally reliable way of finding out is to hold up a standard biro and a permanent marker pen next to the pipe going in to your radiators. If the pipe size is closer to the thickness of the marker pen, you have 15mm. If it looks more like the thickness of a biro or pencil you have micro-bore pipework and need to be much more rigorous in your choice if powerflushing company.
The biggest difficulty with cleaning out micro-bore pipework is purely because the hole that the water and rust that I carries are so very much smaller than 15 mm pipework. If it’s not done correctly there is a risk of blocking the pipe going to or from a radiator completely. And then your looking at replacing sections of pipework. And as most of those are hidden under floors or within walls that is not an attractive prospect.
