How to power flush a system better. Steven from the Power Flush Association and he's thousands and thousands of power flush jobs. And Steven is going to give us some tips on power flushing and some of the things that he does. So hopefully this video should be really, really helpful for you if you're a trainee and you're going to be getting into doing power flushing, then as I say, hopefully this will be really good. Some really good tips in this video. If you could please put a thumbs up on the video, it really helps with the videos. We put a lot of time and effort into doing these videos for you. And also if you could put a comment below, even if you just put power flush, or if you've asked some questions below and we'll try and answer them for you as well. So let's go over to Steven.
Thank you, Alan. My name is Steven and I started the Power Flush Association. The reason I started the association is because there's not a lot of information written online about the real experience and the practicalities of cleaning central heating systems, written by experienced engineers. I myself have cleaned several thousand systems and I find that there is five variables that really matter.
So no system can be cleaned 100%. It's a theoretical ideal. The closest you're going to get to that is in the high nineties. And how you do that depends, in my opinion, on these five factors. So heating the system is important, in combination with using chemicals. The filtering out of the rust and the non-magnetic debris is also important. Flow is extremely important. And how you connect into the system makes a big difference to how close you will get to this hundred percent.
The first variable I'm going to discuss is heat. It's important to heat the system when you're power flushing it or cleaning it by any means, if at all possible. The more you heat it, the softer the rust becomes and the more it structurally breaks down. So if you had a block, the more you can heat that block, the more likely it is for that block to break down and for the rust to be kicked out, back to your machine. Now, when you're power flushing a system, it's kind of hard to have the boilers on. On sealed systems, especially. Open vented you can normally get away with it, running your machine at the same time. On sealed systems because you've dropped the pressure, they don't always want to work.
One of the tips I would say is to connect in a way where you can seal off your machine. So that you can pressurise the system, run it hot, and then open your connections back into your machine. So that you can then flush it when it's hot. And you can do that every time you want to heat it. And there's also power flush machines with heater packs built on. And there's also heater packs that you can buy and connect into your hoses. So there are many ways that you can heat the system up. There's no specific temperature. Any heat is good, but the more heat, the better. So your success rate would be higher if you used more heat for longer.
Another variable to consider is chemicals. So chemicals are important because it helps break down the rust in the system. It's important to understand that it doesn't make the rust disappear. It just breaks it down in the system. The longer you give the chemical to work, the better it'll break it down. And the higher temperature you can make it work at, will break it down better as well. A top tip is to put it in a week before, if the manufacturer allows it. Because some chemicals shouldn't be in systems that long. But it gives the chemical time to work, to be heated up, to work around the system, to soften the rust so that when you come along and do the power flush, it's already been broken down and your power flush can be done much quicker.
So there are different manufacturers for chemicals. Each one has different systems you can use it on, and different recommendations to how long it can be in the system or what it should be used for. I would recommend that you try them all and see what works best for you. Always try and put a little bit more in than the manufacturer says is the minimum. The more chemicals you have, the better results you're going to get, combined with heat and time.
Another variable to keep in mind is the flow rate. So when you have a power flush machine, irrespective of its brand, it will have a set maximum flow rate. So when you connect it onto the system, when you use it in a system, you need to try and maximise that flow rate and not hold the machine back. The best ways to do that is to focus it down to the areas you want to clean. So if you have 10 radiators, close nine of them, close the radiator and focus all your flow through just one radiator.

Great vid and with total clarity to the subject with good presentation. Good job.
Thanks for the time spent on this Allen and Steven, very informative video.
Thank You
Love your videos mate, really helpful! Thanks a lot
This is the most amazing and interesting video I have ever seen on central heating flush because the presenter catch my attention and delivered too many information in short time. Thanks alot Alan for introducing this gem steven to all of us. God bless.
Thank you.
Thanks so much for your advice very useful tips
Fantastic video Steven for your rigorous explanation of power flushing central heating systems.
Thanks very much for your comment, please consider subscribing to support the channel 🙂
Excellent advice Thanks
A lot of good information given very clearly , and good tips simple to incorporate into the power flush job to do. Thank you 👍
Thank you.
Appreciate the time taken to post.
Excellent video! Thanks both of you!
Thank You
Brilliant very clear and confirms why it’s best practice to fit filters afterwards 👍
Thank You.
Really clearly explained, probably the most over looked or ignored area of the heating system, brand new appliances are often fitted on filthy systems, generally to save on cost but cause a whole lot of headaches. Cement mixing trays are a useful waterproof bunded area to site water bearing machines.
Thank you.
Thanks Allen
Her good video Alan. Thanks.
I watched lots of your content before recently passing my acs and becoming gas safe.
I'm a new engineering having retrained.
Thanks for helping us guys who are less experienced :-)
Happy to of been able to help. Good luck for the future. Will you be going to installer show this year? Thanks.
Great video again
Brilliant video. I’ve been power flushing in Ireland for the 7 years. If I had this video back then it would of saved a me some heart ache. 😂 well done.
Thank You
Awesome video! Tips really taken on board!
Thank You.
Great tips guys thanks!!
Our pleasure!
Thank you for posting this video it was very informative 👍

I super enjoyed the pertinent information information giving. Ill be flushing a system in a few weeks and will utilize some thing I have learned here.
Really great video and tips, thanks for posting
Hi Jim. Thank you very much for the comment.
Good job
Excellent video thank you so much.
Thanks.
A really helpful vid. Thanks very much.
You're welcome!
Very helpful video as always 👌
Hi Muhammad. Thank You.
Good video 👍
Another great vid. Thanks
Thank You
Thanks for the video.
Thank You
Thank you for explaing the process as I need to power flush my system raditors some hot at the top and cold at the bottom I now under stand the process better. To complicate this I am made to understand the pipe is smaller than should be used for the flow from the extension to the main part of the house. Thank you for explaining.
Thank You
Great tips yet again
Thank you.
Thanks, really interesting video. Can I ask how you make a decision, for example with old radiators, on whether you flush or bite the bullet and replace rads?
I have done plenty of power flushing and can agree wholeheartedly with everything he says. Particularly the head torch.
Thank You.
Great advice 👍
Thanks.
Thanks
Good tips appreciate it.
Thanks.
Thank you!
Thank You
Good advice, keeping up the standards 👍
Thank you.
Hey allen thanks for the video really appreciated i prefer using this method with the camlock and cutting 2 tees in underneath the boiler if possible and isolate boiler flow and return isolation valves so no debris goes into new boiler or preferably flush before new boiler goes in, some great tips mentioned here 👍
Hi Harry. Which machine do you use? Thanks.
@@AllenHart999 a very old kamco doesnt have a heating element tho does the job i dont do much installing these days mainly service + repair +plumbing repairs thanks allen 👍

All i’ve got to say is…. (Amazing video)
Top quality stuff that.
Thank you.
Great idea to keep flush machines outside, keep off the nice new mono lock.
I’ve got an old 50 gallon rubber storage tank ( remember them )that I put the flush machine in this act’s as a great safe should any mishaps or
Spillage happen.
Putting it in the costumers bath or shower even with a dust sheet I don’t think you would get time to switch it on before you were shown the door.
My machine also has a tub. Thanks.
When I'm doing a Power Flush the first tool I take out of my van is my Parkside (Lidl) wet n dry vac. It's almost the most important component in my Power Flush arsenal. It has saved my bacon on numerous occasions.
Thank you.
Had a George hoover for 20 yrs. essential when doing flats.
Hi Allen always use the Magna-cleanse magnets with the agitator on the rads, how do you think this compares to the flushing machines ?? Great videos by the way !!
Thank You
Thankyou very much brilliant video- especially about remove the inline filter under the combo boiler I did this and clean to increase flow when showering - Also could I just remove one radiator and connect a mains water hose to one side and hose connection to other side of rad and turn tap on to remove magnetite and rust from system - as i haven’t got a flushing machine just a diy guy? Cheers Steven
Thank You
Kemco all the way good video I've experienced all
Thank you.
we are planning on getting a new boiler & replacing the 40 year radiators that are in use but not the ones we don't use currently (which is 10 of 15) - in your opinion do you still think a power flush is needed when you are also replacing the in use radiators ? - wont most of the circulating system sludge be removed by just replacing the radiators & draining down the system ?
Another informative video. Have you ever used a powerfushed a system with the magnacleanse attached to where the magnaclean filter is sited?
My machine has magnets built-in. How do you do it? Thanks.
@@AllenHart999 I've got a fernox powerflush machine and a magnacleanse. Never used both together. I was going to connect magnacleanse to the magnaclean connections then connect powerflush m/c on the flow pipe. Then I have the best of both working together. I emptied a filter yesterday as bad as the one you showed last week.
Great vid
Couple of questions......
I use x800 but I noticed you don’t have a bottle of that on your shelf. Any reason why?
What about agitation with the appropriate tool fitted to the drill?
Where can I get longer high pressure hoses from?
They were just the chemicals we had, we just tried to have all the different brands on there, didn’t want to promote one brand, I like x800 and also the new F8 is very good, we used to use deposit remover many years ago, The drill agitation tool is very good although I used to use a runner mallet,
Flushing a sealed system, can the system be pumped in reverse through the boiler pump?
What happens when power flushing does not clear blockage? Had a boiler upgrade last year but could not get heating to work upstairs. Boiler installer advised a power flush but blockage remains after two attempts. The system is 15mm copper and over 40 years old, iron radiators. I am now assuming I need a new heating system do the copper pipes need to be replaced or can they be unblocked? I am guessing the radiators should be replaced due age. Dublin Ireland
Just to support you and your channel
Thank you very much.
Nice video. Will you discuss power flushing an under floor heating system?
Yes i could definitely do a video on that. Thanks.
Hello Allen, its a big request if you could put a video on how can we connect powerflush machcine, along with Adey Magnacleanse , just to explain how is connection pipework made please
Great video as always. What are your thoughts on stainless steel radiators to prevent rust?
You could still get a corrosion build up, from other components. Like your pump, heat exchanger, even copper. Flux & chloride, within the system. Makes the water acidic.
Stainless Steel rads would end up been too expensive, Also you would need to use lower temperatures. Thanks.
I just had a British Gas engineer replace the heat exchanger in my boiler. The engineer recommended a power flush because he said the water was very dirty and it became like this because someone left the filling loops on the boiler open. This problem was affecting my hot water as it only remained hot for the first 7-9 seconds after which it became freezing cold. How can I maintain my boiler to stop this from happening ever again?
If flushing radiators why can’t you shut both trv and lock shield then remove both top fittings (air bleed and blanking) and flush from there?
how to clean Potterton pro max combi boiler main heat exchanger without dismantling it ?
When I had a PF a hand drill fitted with an attachment set on 'hammer' was used to vibrate radiators and agitate them. The idea was to disturb any sediment / rust etc.
Mine snapped in the drill 😂
I am having my system power flushed next week it is well and truly clogged up. They will do it in a day. This means they will not be putting any chemicals in my system until that day. what can I do myself (I have no knowledge of heating systems), to help a more successful job of what they are going to do. I f you suggest me putting one kind of chemical in the system where and how would I do that.
I sometimes use a Rad Hammer to dislodge stub Magnetite cold spots. You can use a rubber mallet, as an alternative. But the more blows per minute. The more effective, the results. You can see sudden gushes of black sludge coming through.
That’s a really good tip. Thanks.
How do you rate Magna flush?
Hi There, Good video. However, tried to submit a request for a quotation at the Power Flush association website and was unable to as the site isn't working.
Great videos alan but what is a good power flush system to rent for me to power flush my 3 properties my self (diy)
Thank You
Hi Allen, decent vid but I have a few questions. Have you any good tips on flushing microbore ? I've found powerflushing pretty innefective if badly blocked regardless of where you tee in. Also do you think the filters reduce flow rate too much, is magnets dangled in machine a better way ?
Only thing I didn't agree with in vid is machine in bath asking for trouble in my opinion. Always outside if possible get your steps in and build a dust sheet tent if it rains.
Personally i do not put it in the bath. I use a big tub.
Microbore can be very very tricky.
Treat microbore no different from a normal system. I have been powerflushing for 20 years, done a couple of thousand. he is waffling on a lot of nonsense despite saying a lot of good stuff too.
No aday after cleaning with machine and chemicals, i use a kit that connects to mains water and allows me to reverse the flow just like power flush machines do, but a lot more powerful and sorts out harder blockages. Sometimes i don't even use the machine as the system is already topped up with chemicals, it then takes me 3 hours to complete 12-15 rads system. Magflush solutions based in London.
Thank You
What’s your take on vibrating the radiator using a hammer action drill?
Depends on the system and how bad it is. They do work though. Thanks.
Very informative video. If everyone followed thes tips, combis would soon gain a much better reputation!
Hi Mike. Flushing is definitely the answer to a lot of issues.
Does the boiler have to be working to do a power flush? Can you do it after a new boiler install?
Thanks for the question. No it doesnt have to work but its better if it does. Thanks.
I have a powerflush machine that I rarely use, I wonder is there much of a risk of causing damage or a leak to a system with by using it?
They very rarely leak. Thanks.
Hi Alan, can you power flush a system that’s all 12mm plastic micro pipe, and how often should I clean the magnetic filter. Thanks.
Hi Dennis Thank you for the question. Micro pipe can be powerflushed but not always easy. once the system is clean then i would clean the filter each year on a service. Thanks.
@@AllenHart999 thanks for that Alan, and your quick reply.
@@dennishumphries9406 No problem.
Hi alan I have new Boilar installed and they didn’t do hot or cold flush for the system when I asked them they said it’s no need for it the magnet cleanr will do the job
All systems need flushing to BS7593 Thanks.
@@AllenHart999 many thanks 👌
Pete please please make sure you have nothing bye passing best way is to turn off all rads , you should have no flow from your return, also don't forget to flush the plate heat exchanger or coil.
Thank You
#Alan your a legend :)
It will be very helpful if you download a video how to power flush unvented sealed system thanks
I have done loads of videos on powerflushing. Thanks.
How often should you drain your central heating system?
If the system is clean and treated well it shouldn’t need draining. Thanks.
How often? Treated well? Means if the whole system was brand new, and it had inhibitor in it? How often? Every 5 years?
A colleague use to have a kid’s inflatable paddling pool he use to sit his machine in, just in case of spillages.
Thank You
Any advice please
Thank You
Allen,Ball park figure what the cost of a power flush for a three bed semi D.
Really depends on what's needed. Not cheap to do a good job though. Thanks.
@@AllenHart999 So what would be needed Allen? that was like a builders quote the big suck in of air and then well that will depend. IT was just a ball park figure i asked for .
Any good flush machine should be capable of 0.75>1bar operating the pressure switch, allowing the boiler to heat. The challenge is if using chems not compatible with alloy and should not be flushed through the boiler. Either heat the system before looping out the boiler or invest in a secondary heat device. Norstorm are a great unit.
Thanks.
I wish this guy could do my system. Plumber said my system is completely blocked and can't do anything about it. If anyone can do it this guy can. I'm in Swindon. Message me please.
whats the best chemical to use
Personally i have used F5 and X800 for years and always found them ok. You can get stronger chemicals though.
Power Flush
why central heating pipe gets hotter than hot water pipe even when heating is off
What brand of chemicals does this chap use
We are not trying to promote any brand. Personally i use Fernox , Sentinal or Adey. Thanks.
Why does your jumper say powder flush
Does the location of placement vary on vented un-vented or sealed systems? I really don't understand why some installers get hyped with the amount of magnatite that collects in magnacleanse filters. There really shouldn't be that much rust in system.
Secondly some engineers changing plate to plates on an already dirty system leaving at it that. The new plate will most probably incur the same blockage. At least suggest a system cleanse.
If you have rads over 2 or 3 floors how is it that you keep them half full? Does gravity not bring the water to the lowest point? Meaning the lowest Rads are always full.
The most important thing I find is to write up a contract and get the customer to sign it. Old systems tend to bring up pinholes in Rads. You get the odd complacent customer. Believe me you don't want that biting you in b**t
Great information there guys. I picked up a good few pointers here. 😉
Hi Ray. Thank you so much for the feedback. Changing plates are almost pointless on really dirty systems as you say they will block up again. if you fully drain the rads and then refill you will trap air in the top of the rads and this will help you clean it better. Remember you need to open the air points when you drain it though. Trade help do terms and conditions for free on there app ruclips.net/video/32Fq11ubjps/видео.html
Thanks.
@@AllenHart999 Thank you so much Allen. The information you give is invaluable 👍
@@rayc1503 No problem and thank you for watching.
How many disasters have you had? I.e fitting blow off due to power flushing underfloor or similar?
So systems that are 90% installed in plastic are less likely to have rust,
Thanks
Thank You
You still have Radiators that are metal that is where most of the rust comes from, not copper pipes.
👍👍👍
