What’s the difference between a power flush and a chemical flush?
"Power Flush vs Chemical Flush: The Ultimate Comparison"
A chemical flush and a power flush are two methods used to clean central heating systems, but they are different in terms of the process and equipment used.
A chemical flush involves the use of chemical cleaning solutions to break down and remove debris, rust, and buildup from the heating system. The cleaning solution is circulated through the system, and then drained along with the debris. This process is usually performed by a professional heating engineer.
On the other hand, a power flush uses high-velocity water to physically flush out the debris, rust, and buildup from the system. This process uses specialized equipment such as a power flushing machine and is also performed by a professional heating engineer.
Both methods are effective in cleaning central heating systems, but a power flush may be more efficient in removing heavier buildup, while a chemical flush may be better at breaking down and removing more stubborn deposits. The choice of method may depend on the individual heating system's needs and condition.

I looked at a poweflush and the cost was extortionate tbh,my issue is ive got bottom of house 15mm plastic repiped but top half is 10mm copper micorbore,some said it wouldnt work and didnt even want to try,the ones that said they would wanted crazy money,boiler is condensing type around 6yr old and upstairs rads are cold,so i bought the X400 and flushed the sentinel magnafilter,refilled system with the x400 and now only 8hrs later have decent heat upstairs now,not as good as it shpuld be but a huge improvement and good enough,the rads are all around 3yr old but to repipe upstairs is no no as it means ripping up floor in 2 rooms and hall,weirdly the towel rad has always been fine upstairs but 2 rads on same floor were always very poor,there is a manifold in hall so not sure if thsts an isdue.
Very well explained, thank you.
Great video - I;ve noticed when I bleed my radiators the water coming out is quite creamy, would this suggest gunk? or something else? all rads, boiler and pipework are only 14 months old. Boiler just serviced and the engineer said the magnafilter looked fine.
I have a fairly new boiler, all rads are brand new apart from an old towel rail in a bathroom. We are currently renovating and I think the crashing and bashing keeps loosening debris and it ends up blocking the heat exchanger. Will the chemical flush and drain down release the debris in the heat exchanger? TIA!
How much does it cost .for 2 beds house with 5 radiators.
Great video. So you say to insert the chemical and leave the rads running for an hour to circulate it around. We then drain off the system to get rid of that slugey water. We then put the inhibitor in - do we drain this or leave it in there to circulate? Thanks buddy
Hello 👋🏼 Leave the inhibitor in the system. This prevents any further corrosion. It prevents the system of corroding from inside out and therefore prevents build up of sludge. Hope this helps :)
@@flushman makes sense. Thank you for the quick reply
Thank you, very helpful!
Thank you, that was really helpful. I’ve heard of a power flush, but not a chemical flush. How easy are power flush machines to use. I believe you can hire them? I ask because I was I was quoted £850 plus VAT for a power flush (3 bedroom house with 13 radiators)
Rip off.
Shocking absolute rip off I was quoted similar,issue can show up leaks if powerflushed and they do usually warn you of this.
question:
what happens if you power flush but you have no open drain outside?
my drains are sealed under the ground.
some people have said they put the contents straight onto your garden which i think is bad idea if you are putting corrosive elements onto soil( is it even permissible to to do that !)
also is a power flush more suitable if you believe your system has never had a power flush( mine is at least 14 years old and came with the property)
thanks
Leave it alone.Is your system ok? Radiators hot don't worry.
Can you power flush micropore pipes 8mm
How much roughly would this cost and how often should blsystem be flushed ? Thank you.
Hi, you can find out more on our post here… www.flushplumbingandheating.co.uk/power-flushing-west-london/
All 4 rads on my ground floor have drain pipes so how to I know which rad to add chemical?
it doesn't matter...once it is in it will circulate
Best idea is if you have a towel heater use that,once drained down close both valves fill with the chemicals flush usually 1 ltr,prime system and open both valves then bleed rads as normal,the towel rad is easiest as the bleed valve is at top and you can remove it plus there's no trv valve.
My partner has just had under floor heating fitted downstairs under floor and rads mainly upstairs. He’s had a new boiler fitted and they didn’t mention that they’d cleaned the system first. Is this bad practice? The system has never been cleaned in 15 years. Could this damage his new boiler? I had a new boiler fitted and knew I needed a power flush. Old system, problems with my old boiler. The builder in charge has said it nonsense he didn’t need a flush and it’s an unnecessary procedure which is used by heating engineers to get more money out of people. Please advise. Thanks
If they don't clean the system the boiler will knackered
@@richlee509 that’s exactly what I thought . Thanks for your reply
What do you think of flushing with the filling loop going round knocking each rad off individually until each rad runs clear?
Yes I use this method too. It depends how contaminated the system is. If the system is lightly effected then this method works well :) 🔧
What the point of adding a magnaclean to your machine when the crap would just go into the drain anyway through your machine....seems that it's more to show your customers some of the sludge
@@naveedahmed5509 Yes it’s certainly good to show the customers but it also speeds the whole process up and you reduce how much water is used during the flush. You will find you don’t have to dump as much water when using a filter. I also drop a loose magnet in the tank too and keep cleaning it. I would highly recommend using a filter :)
@@naveedahmed5509
Because the system is dosed with chemical cleaner which puts radiator magnite into suspension its then caught by the magnaclean/magnet
What did people do before power flush.???
Pumped the water main through the system
Why not add chemicals to the top tank?
What is the black stuff on the back of your head?
I think he missed it when he shaved his head.
I'm installing 3 new radiator
Just replaced the old one
I have a single pipe system
After that , my all radiator is not working. Please
help me. Kind regards
Thanks
