- In this video I show you how to remove a radiator without draining down your central heating system. This is useful for simple tasks like painting the wall. In the video I give a full step by step guide of how to identify types of valve, how to turn them off, how to drain down and remove the radiator. I then show how to refit and refill the radiator including how to re-pressurise your central heating system, and as always a few useful tips along the way!

This is very helpful and easy to follow. The two top screws holding one of my radiator have come loose needing redrilling new holes. Rad is wobbly. Thought I had to empty the system to remove the rad to fix the screws until I came here to watch this video. Thank you for this well presented video.
Thank you so much for explaining this, you’ve already made my weekend. I need to remove one panel to fit new skirting but wanted to avoid draining the whole system down and losing all the sentinel one inhibitor. Definitely a Diy’er task.
Spot on! Confident I can manage this without the services of plumber. Much Appreciated.
Well done for explaining why you should count the number of turns when closing off the valve -
because of balancing. It makes it easier for DIYers like me if I understand why I have to do something a certain way. Thanks.
Best step by step videos I've seen on CZcams so far. Well done Pouse
Thanks for the kind words, glad you found them useful 👍

You legend, thank you. Your tut gave me the confidence to replace my first radiator. Good advice on how to keep the system balanced by counting the turns of the valve. I had to replace a two-column vertical radiator and 10 minutes in it had me wondering how long it would take to empty (20-30 min eventually). When filling it back up, it took a good two minutes before I had water coming out the bleed valve. In between I had to top up the main system as it dropped out to zero. As a newbie I would just add, surround yourself with loads of towels and a couple of buckets, make sure you know how to top up your boiler, make sure you have all the tools to hand before you start, and go slow. Thanks again.
Useful, no nonsense video that focuses on how to remove/refit a radiator. Thanks.
Glad you enjoyed it.
Absolutely superb video! Great info and a very clear explanation of not only how to put the rad back on but also how to balance the system.
Glad it was helpful.
No matter how many times I do this, I always get confused about which way to turn it. Knowing it's anticlockwise turning outwards is a great tip to remember going forward.
Really clear & informative video. Super easy to follow - thank you!
Glad to help 👍
Thank you very very much!!!
A very clear and concise video. Easy to follow and understand.
Thank you again!
Really helpful and honest video...especially the part when bleeding the radiator 🙂...Thanks!
Thanks perfect timing. I've had my radiator off for plastering. Managed to refix the brackets to the wall and hang it back up. But haven't yet bothered re connecting the valves and filling it back up. Will have a go at it tomorrow. The pressure guage on my boiler doesn't have a green bit so I've taken a photo of the pressure it was at before starting, and get it back to that pressure.
Taking a pic is a great idea, best of luck with it and thanks for watching.
Great video, easy to follow and no annoying muzak. Thank you.
No problem, glad you enjoyed it 👍
Great video. I'm contemplating changing my bathroom radiator for a towel rail type. Fortunately I have shut off valves either side of the rad so there shouldn't be any leaks from the system but the rad still needs draining and I was unsure how to do that. Your video has explained perfectly and very well presented too. Thanks for the tips. And I've subscribed. 👍
Thanks for the kind words. Glad to help, and best of luck with the radiator 👍
You're very welcome Pouse. 👍😀
Need to do this for decorating our bedroom and found it very informative! I'm a lot more confident now I know I can follow this video! Thanks!
Glad to help 👍
thanks to your video makes me convident to do this myself, very clearly explained
Thanks for the feedback 👍
This video is great. Informative enough to make me confident I can do this.
Hope it went well 👍
Great simple video exactly what I need to do. Love the fact you're keeping it real by using old pants for your rags !
Reuse before you recycle! I even downgrade my everyday clothes to work clothes before they're demoted to rags....you may have noticed 😂. Thanks for watching 👍
Very well explained Pouse. Thank you very much.
No problem.
Such a helpful guide. Thanks mate 👍🏼
No problem 👍
Very clear video! Thanks. Also funny that we can recognise the "Rag" you used to catch the water... :)
Just about to change a radiator so thought I’d just check that I’m doing it correctly. Thanks for the video
No problem 👍
Great video..the best straight to the job well explained thanks.
Glad you enjoyed it 👍
Brilliant thankyou! You made it look easy and I'm going to give this a go :)
Really helpful video . Thank you
Thank you- really well explained..will save me £££££'s!!
Great video, clear and easy to follow. Loving you using your old boxer's for bleeding the radiator! Haha
Reuse before you recycle! Thanks for watching 👍
Great video, very helpful, thank you
Glad you found it useful 👍
Excellent video is it worth dumping some inhibitor by opening the top valves of the rad before opening the valves on either end to repressurise it...
Left a comment before and didn't remember to say that most radiators have a lot of antique dust and gunge behind them, so this method really allows you to see to the gunk and likely allow for better heat radiation.
Thank you for your excellent video, explained very well and easy to understand..
No problem, glad to help 👍
Nice one Pouse👍🏻
Thanks for watching!
What a fantastic video
Awesome 👍
Useful lesson
Thanks for the feedback.
Awesome video, appreciate this very much. Thanks
Glad to help 👍
excellent instruction Pouse
Muito bom 👍👍
Very helpful thank you. Is there any way of changing the values and pipe below without draining the system.. I need to replace a damaged pipe you see.
Another tip don't leave it out the front cos the fookers will have it on a scrap van before you've put the kettle on.
I never leave any metal out the front around here!!
😂
Great video
Around my part of the green and pleasant land we don’t have to put the scrap out the front they just come in and remove it from the wall when those of us are lucky enough to have a job are at work 👍
great video 👍
Cheers. Great video
Thank you.
Brilliant, thank you so much
You're very welcome!
Little tip...if you are storing the radiator inside while it's off, nip up the bleed valves and flip the radiator upside down, it definitely won't leak then.
Another tip....don't rely on a TRV being turned right down with the radiator disconnected, always best to lock it off with the little cap it came with. I knew a guy who flooded his house once because he did that. It was real cold weather and the thermostatic valve opened when he wasn't about! Oops!! (He might chip in if he's reading this! 😂)
I think I know that guy!!
Not sure if you chaps are still about, but I,ve tried this today. All went well until i saw the boiler pressure right down. Decided to add some water in, assuming I'd locked off each end, but the thermostat side in OFF still p*ssed water everywhere.
Do you put some inhibitor into the radiator to ensure you keep enough in the system? Great video
I didn't on this occasion but you can. Easiest way to add it is through the top of a heated towel rail if you have one as the valve is on top. Hope that helps. Thanks for watching.
Excellent video Pouse, I always need a reminder for this job! Looks like a pair of your old boxers at 15:30 😉
Always the old boxers, reuse before you recycle!
Are modern radiator brackets universal? For example could I replace a Kudox radiator with a Stelrad radiator of the same dimensions without having to replace the brackets?
What about the old and heavy cast iron rads that sit on the floor. Any suggestions
is it possible to chase the copper piping in the wall for the radiator ? & what if anything do u need like insulation for pipes ??
Yes you can chase copper pipes in wall. You can lag them with various materials these days prior to plastering over them but it's making sure you have enough room for your pipes and lagging. Hope that helps. Thanks for watching 👍
I was going to change mine … but I’m now going to get a plumber in !!! Fuck that 😂
Spot on that pal 👍🏼 I need to stick some wallpaper back down behind mine… just a quick one though, I have to keep topping up my system so what would be the cause of that?
If it needs topping up, either air in your system, or you have water leaking or weeping out somewhere. Try bleeding all your radiators, refill as you go so not add more air. Then see if that works. Best of luck.
Great video, thank you. My boiler hasn't got any loop valves or a pressure gauge... how does it add the extra water? or doesn't it matter on my Conventional 15yr old boiler? thanks
If it’s not a combi boiler it won’t have these.
I use my wet hoover and just vacuum the water as it comes out. If a smaller rad I'll cling film over the rad valve and elastic band it in place. Rad can then be carried outside and emptied.
Nice tip, thanks! 👍
No worries just found the plastic end on rad key kept turning got a solid key all ok now 😂
So funny just changed over my bathroom radiator in exactly the same way. Still watched your video though.
You must have too much time on your hands! Thanks for watching.
I don’t suppose you could please confirm the make of this particular rad? I’m asking as I have one exactly the same at home in my bathroom and it’s gone rusty and needs replacing. Many thanks.
I use a rubble sack to drain in to. You can pull it up behind the rad and valve so it doesn’t spray over the wall.
Thanks for the tip and thanks for watching!
I'm needing to change out a valve that's seized open on one of my old cast iron radiators. It's located in my living room, and is directly over the boiler in my basement. It's the first to recover hot water and is the hottest radiator in the house. As a result, the heating throughout is not balanced. The problem I'm having is that i would like to do this without draining the system, but i believe that's not possible for me to do because all of my radiators only have a valve on the entry port of the radiator and not another valve on the exit port. In my situation there's really no way to do this without draining the entire system, correct?
Good detailed video 👍
Thanks 👍
Would it not be easier to put a small hole in the bottom of jug so water goes straight into bowl instead of taking jug away to empty.?
If you have the rad off for a day or 2 can you use the heating as normal?
Yes, just close the valves down by the removed radiator and it will be fine. When you add the radiator back on you will need to bleed the radiators as per the video and repressurise the boiler. Best of luck 👍
Why didn't you use the drain on the rad valve at the other end .....plus people please please please if your radiator has a thermostatic valve either shut it with the manual decorators cap or fit a brass blanking cap to the valve exit cos they have been known to open on the frost protection setting
how to check mains water pressure in the house please
How would you know which side is the lock shield and which side isn't. If both caps on each end of the radiator are missing
Not all rads have trvs.perhaps he has his thermostat in the landing hence no trv on the rad.
Trv should have a thread on it
@@incorrect1844 I have an old rad where both caps are missing and the valves that turn look identical so unable to identify a lock shield
@@shoudd then you have a radiator with double locksheilds so it’s either an older system or that radiator is situated closest to the room thermostat (if you have one) take note of how many full turns it takes to shut off both valves as you will need to open them up to the previous position to reduce any issues with balancing ie: that radiator either takes all the heat and the others don’t perform as they did or that radiator will not heat up also depending on the age the locksheild may start pissing water at you as soon as you turn it or when you open them back up the gland but may leak…. Have fun with that or alternatively just call a plumber….?
Might both be lock shield like mine. I have my thermostat in the room with the rad in the video, hence I had two lock shields. Hope that helps. Thanks for watching.
Wheel head and lock shield is a naming convention, a wheelhead valve is the valve on the flow circuit ie out of the boiler, the lock shield is on the the return circuit. They usually are identical, what is different as Pouse showed is the cap. Think of them as two sink taps one with a handle to turn off and on the other with the handle missing. Why? When the house is first setup the heating system needs balancing, all the valves to each radiator are open, when the heating is on, the radiators far from the boiler will be slow to warm and those closest to the boiler will be toasty hot. Simply, the pump is pushing water around and the water goes through the radiator with the least resistance. By partially closing the hottest radiator valve on the return circuit we restrict the flow and the radiator has less water flowing though it so it is cooler. This time consuming job is complete when all of the radiators are the same temp. As we don’t want anyone messing with this “balanced” setting, a cap that spins and cannot accidentally be adjusted is placed on the valve ( the lock shield valve) We can turn off the radiator using the (wheelhead)valve on the other end of the radiator this has a cap that can turn the valve. (This is the valve that is replaced If you want to put a TRV thermostatic radiator valve on).
Once the lock shield is set along with the other radiator’s it is left alone. To the poster who has no caps on the radiator, then the one that gets hottest first is the one you use to turn off and on the radiator. If both the valves have been messed with merely fully open both of them and after the heating has been on for a while hold your hand on the radiator and compare with the other radiators in the house, it is too hot compared with the rest of the rads in the house then partially close the lock shield valve on the return circuit (at the opposite end of the the one that got hottest first) adjust until it matches the other house radiators. Check you’ve got it right when the heating is next on, Mark it with some paint and leave that valve alone or buy some radiator caps.
I think of the names, wheel being one you can turn and lock as one that is locked and don’t mess with.
Help when bleeding radiator the bed nipple won't stop turning to stop water what do I do
Great, I'm about to replace a radiator, problem, the one I'm removing was installed without valves.
Tried it yesterday, sadly didn't work. Closed off left and right as far as it would go, opened the bleed valve and air and then water shoots out suggesting that the inlet on the bottom won't close all the way 😢
If you get an old pair of rubber washing up gloves cut off a finger. You can stretch it over the radiator pipe and keep most of the water in the radiator to take it out and then drain it.
Great tip, I might try that. Thanks for the feedback and thanks for watching John. 👍
How to know which valve is balancing?
I don't think I icolated my radiator first, should I still follow the same steps
Nice pants!
Whey didn't you drain the radiator using the drain valve fitted on the left hand side of the radiator.
Do you know a way to remove my wall radiator without draining the central heating system?
I will use a garden plastic rubble bag to collect water from radiator
Best of luck with it.
Man you gotta get rid of that annoying sound effect. I’m surprised you’ve kept it for this long despite all the complaints in the comments.
Which sound effect? The music at beginning and end?
@@POUSEaroundtheHOUSE it’s at 0:24
If your watching this in 2023 and you go it regularly. Buy a wet vac. Inexpensive and saves a lot of time and mess 😊
Good video. But as soon as you touch lockvalve after a few years it starts leaking.
Hy
Why did you just drain the radiator using the drain off valve on the radiator woild have made less mess
That would of drained the whole system though. 🤭🤪🤣
