How to fix a thermostatic radiator valve if your radiator is not heating up.
ฝัง
- เผยแพร่เมื่อ 11 เม.ย. 2013
- If you have a radiator not heating up a faulty thermostatic rad valve could well be the cause. If you have tried bleeding and checked the lock shield valve is fully on at the other end of the radiator, then chances are your thermostatic radiator valve is stuck in the off position. This simple fix shows how to quickly and easily fix the problem. If you have a very old Danfoss model then do not try this as the pin will come right out, you will have to replace this model of valve.

Dereton33 - may small children sing your name. You have a spot reserved for you in Valhalla. We are not worthy to walk amongst you. Thanks! Video worked a treat!
Ha ha great it all worked out for you. Not sure about making it to Valhalla though.
I second that 👏👏👏👏😊😊😊
Thanks so much!!! Saved having to call a plumber and fixed it myself in 2-3 minutes. These kind of checks are things that everyone should know how to do as you're not really going to break anything (provided you have common sense and don't get too violent with the hammer/grips!) and it can save so much grief!
You just saved me from calling a plumber out. Simple video, well explained, straight to the point. Many thanks!
We have just tried this.....amazingly simple and you've saved us taking off the wall and draining it. Happy to make a donation to a charity of your choice. Thank you.
No problem.
this is amazing my friend! great work and demonstration!! I was waiting the whole day today for the plumbers to come, nobody showed up and then I found your video...how brilliant!
+Maria Peleli No problem.
Thank you! My radiator has been cold for days, this fixed it in seconds!
Thanks Al, my kids rooms have been getting very cold lately, and I had tried bleeding and checked the lock valve and I was about to call someone to look at it when I found this video. Totally sorted my problem, and saved me a large call out fee, thank you so much!
No problem Rob have a nice warmer Christmas now .
Kind regards,
al.
Just wanted to say a big thank you, I followed your advice and I now have a working radiator! It was stone cold before, but thanks to you, it’s sorted! Huge thanks! 👍
Great to hear!
Mate, brilliant! you saved me the cost of calling a plumber out. Had this exact problem fixed it in a minute thanks to your vid. Much appreciated!
Likewise 🙂
can't believe I didn't come on TH-cam sooner. this video would have saved me some cold nights. many thanks
Same, eight years of cold nights lol
Same... Thanks to this guy!
Thanks for these. My kitchen rad had a leaking lock valve on one side and a stuck thermostatic one one the other. Watching your videos got me sorted in minutes, a length of PTFE sorted the leak and a gentle tug with pliers lifted the stuck pin on the other.
Plumber's children will go hungry thanks to you (wink)
That was a quick and easy fix for a rad at home. It had been turned down on the thermostatic valve, but then never came on again after I turned it back up. The system is old, and after seeing how to remove the top of the valve a couple of taps with a big pair of pliers (seem to work like a hammer) made it ping back up. I won't turn that one down again until the valve is changed. Thanks for the video.
Hi Sevenman , it1s the little tricks like this , that make plumbers a lot of money.
Kind regards,
al.
Thank you! The radiator in our spare room has been broken for months, and I attempted fixing it by bleeding but nothing worked and there didn't seem to be any air locked at all. Finally looked up alternative solutions and your video was spot on for fixing! Pin was jammed, light tap with a heavy object (or several taps lol) and eventually it worked! Haven't felt heat from that radiator before! Thanks!!
Absolute legend ! Thank you for posting this, really pragmatic and easy to follow guidance for a simple yet frustrating problem 👍 Warm bedroom now, happy wife 😅
No problem.
Thank you for making this. Seven years later you've saved me a lot of money for a simple 10 second fix that even I managed to do.
No problem.
Fantastic, fixed in seconds and so easy. House has been cold upstairs and I realised landing radiator wasn't on, then realised it wasn't working. Few seconds watching your video and heat is blasting through. Thank you so much!
No problem gerard.
How wonderful to bring warmth and happiness too so many people,God bless 🙏 you 💕❤
Dereton, mate you are a life saver.
Just fixed a radiator in one of my other room as one of the tenant was complaining that the radiator was not working. I bled it but didn't work. Called up a plumber, he said he can't come before saturday. So was checking on youtube to see if there is any helpful advice or not.
Saw your video, tried exactly as you mentioned and now its heating up.
If you are in London then will take you out for drinks some day.
Keep up the good work.
PS, I do have one other problem, its the leaky radiator, those upright ones. Would you be able to make a video of that as well?
Thanks again for all your help.
Ripon Biswas I have a video on how to repair a leaking radiator valve but if your radiator has a rust hole or leak on a seam then there is no cure, the radiator has to be replaced. Al.
Nice one, kids room was freezing and wide was panicking, watched your video and quickly sorted it. Everyone happy. Do you have a way to send a donation to buy you a beer?
Don`t worry, put a fiver in the next charity box you see.
Top man! A plumber showed me this a couple of years ago but I'd forgotten. Great video, nice and simple, 2 radiators now back working and just in time for the first frost expected overnight. Thanks.
Graeme Black No problem. Al.
You sir are an absolute legend. Had tried everything with one radiator in our house that just wouldn't heat up and this has just fixed it in a few minutes
Great to hear!
God bless you dereton33! thanks mate
No problem
Kind regards,
al.
My man!!! It worked!!! Just whack it a couple of times!!!
Brilliant, spot on, just about to call a plumber - I'd have been gutted to find out how simple the fix was! Also, you gave the confidence to actually unscrew the valve - I wasn't sure it was sealed underneath - learn something new every day 🙂
You're welcome!
Thanks for the video, never done any DIY, fixed radiator with help from your video, saved me the cost of getting a plumber out
florrie Hatton No problem florrie. Al.
Brilliant! Worked perfectly. Many thanks.
No problem.
Just a little tap with a hammer , bingo it works ! cheers
+Lance Wilson Ellis No problem. Al.
Thank you so much! After 2.5 years of living in this flat with only hot water and no heating, you have fixed my heating! Another video suggested not to use a hammer to the pin which worried me until I stumbled across your video! I saw it pop outwards and immediately the radiator got hot. The flow pipes got hot and my heat meter is now recording flow/temperatures! Why I didn't do this before but you saved me a call out. Thank you!!
No problem.
Honestly worked wonders! Thank you! Fixed my radiator - even as someone with very limited plumbing knowledge who happens to have a housemate with a hammer, managed to get the radiator going again, for the colder nights
Glad it helped
Thanks for the video - followed the video and quickly fixed two radiators in my house. Nice!
Ive got 3 radiators that havnt worked for about a year, and im now determined to find out whats wrong. Thankyou so much for your easy to understand videos. Tomorrow i am going to give it a try to get them to work! Fingers crossed x
Good luck Jan.
That's great thanks! I was thinking I would have to replace the valves but this worked a treat. Took me longer to find the pliers and hammer than to fix the problem in 3 rooms!
These jobs are always easier than you think .Pleased you did it ok.
Kind regards,
al.
Thanks for your advice. It helped me fix a TRV that was permanently fully open. I was worried about how big a job it was going to be; it turned out to be an easy and quick fix as the pin had become stuck in the up position and the valve head had become loose enough to just push up instead of exerting pressure on the pin.
Most plumbers would have charged for a drain down and stretched the job out a bit , so good on you for doing it yourself .
Kind regards,
al.
THANK YOU SO MUCH. 5 radiators have not worked in weeks, decided to go onto TH-cam to find a fix. Did what you suggested in the video. And now they are all piping hot. Saved me a fortune, and taught me something about plumbing - if it doesn't work hit it with a hammer.
Ha ha works every time.
Hi Al, Superb advice a stuck thermostatic radiator valve was indeed the culprit I followed your instruction to the letter, removing the control top and taping the brass valve which then sprung back into action top back on job done.
Thank you Al.
Kind Regards Steve.
had a guy in last year he mentioned this problem and now I can fix it myself...
awesome vid, tyvm
Cheers dereton33 Two rads went down a few months ago. Bled the rads, tried rebalancing the rads but no joy. And then two minutes watching this saved me who knows how much. Top man. 👍
Glad I could help
Fantastic. I also had some green corroded copper on top the pin. I thought the thermostat was fairly new (I then found out it is 11 years old!), but one light tap with a hammer released the pin and up It popped. The radiator then immediately started to heat up. It took me longer to find a hammer, than to remove the top casing, tap the pin and replace the casing. Job done - and I was getting ready to pay £50 to call out a plumber (sorry Mario)! Great job. Thank you for showing this.
Thanks for this very useful video - I followed your advice and it worked great. Let me say I have great respect for plumbers and am always happy to call one out when the need arises.
Excellent!
First try as a plumber, your solution worked perfectly, also used WD40 to prevent the pin from stuck again. Thanks a lot!
+kalidor.ch No problem
Thank you so much! I've never been afraid of tackling these things... but I was wary of taking the top off the valve without breaking it in the process. I now have two very happy parents, thanks to you. :)
No problem Justin.
Seven and a half years later, I found your video and it's worked a treat for me.
Cheers for that.
🙂👍
Glad it helped
Thank you so much! I've got two radiators that weren't working, one for maybe 8 years, the other for maybe 4, that now work perfectly. I really appreciate it!
You're welcome!
You are a God send. This video is 8 years old and totally relevant. Just fixed my radiator by tapping on the pin as demonstrated. Thanks
You're welcome!
Dear Al,
thank you so much, i cant tell you how many hours of work you have saved me. wife and children are delighted and warm- result !!!!!!!!!!!
No worries pleased you managed it ok.
regards
al.
You Sir, deserve a medal. Thanks for solving my radiators exact issue. Cheers!
No problem.
Saved me calling out a plumber - had my radiator sorted in just a few minutes, cant thank you enough for this excellent vlog - Thank You.
Glad it helped Stuart.
Thank you for that. It's bloody freezing and my bathroom radiator hasn't worked for at least a year. This took two seconds and is making a big difference. Thank you so much.
Marc Mckenna No problem Mark. Al.
Hi Al: many thanks for this tip - I bashed the jammed pin on our stuck rad valve with a hammer, and, hey presto, it popped up and the heat came through right away. You're a star!
No problem.
Thank you! This happened on this radiator before, about 5 years ago, so I knew it probably to do with the valve. Yep, a quick twiddle with pliars and a few bangs with the hammer and I have heat agin!
Thanks very much sir! Your video got my radiator warm again! Would have had to wait a week for the engineer to come round and at about £80 call out fee! My valves under the TRV were very stiff so used a touch of WD40 on it too in addition to the hammer action, which instantly got the valves bouncing up and down again! Very much appreciated 👍
No problem Andrew.
Thank you sir so much for this video! I'm a complete novice and was tearing my hair out and this sorted it straight away. Thanks again
Hi Simon , pleased you sorted it out ok.
Kind regards,
al.
Amazing, thank you ! After 8 years of no working radiator in my living room,finally today thanks to your video,it's fixed,can't believe all this time and the fix was so simple. I only came across the video while browsing your videos for one that would help me to fit a new bathroom sink,i'm starting with what I feel is less complicated before moving on to replacing the toilet and then bath. I got as far as fitting the waste and taps to the basin, taps still seem to have movement but i'm scared about overtightening in case damage/crack the basin.
Just take it nice and steady Carol and you will do it fine.
Been trying to ages to fix a radiator, found your video and fixed it within 2 minutes. Thank you so much!
You're welcome!
Mate - Thanks a million for this. Im a kiwi unfamiliar with UK rads, & your clip just saved me the cost of a plumber. Many Thanks
No problem Doug.
Still a valid video in 2020! I had a spare valve but thought i'd TH-cam it first! Saved me a right ball ache. Thanks very much!
You're welcome!
Even after many years this video still comes to the help of a broken sad rad and family. Thank you so much for the tip :D
Glad I could help!
Your a genius. Have been having problems with a radiator and was about to call out a plumber.
Great video!
Took off the thermostat and the pin was already up. Hit it with the pliers a couple of times, but this did nothing. Put the thermostat back on and it was working.
No problem
Thanks, just fixed a bad radiator of bout 6 weeks after watching this. I was all ready to have a new valve fitted as I didn't realise that it was so easy to mend. I'm going to your radiator balancing video next as my father in law opened all the valves to full a few years ago. Ta lots.
No problem.
Thanks a lot man! I used a couple of pliers to push and pull and pull the pin until it let loose.
I actually managed to let the pin out of the socket, but managed to push it back in without any issues.
Thanks very much for the advice - fixed three TRVs so have a warm family once again and avoided needing a plumber coming out. Cheers!!
No problem Nick.
Spot on! Bled my rads and checked the lock shields and no joy, checked the pin under the thermostatic and it was stuck partly up and wouldn’t move, saw on your vid it has to move quite freely so got brave and got the pliers on it and bingo popped right up and went hot straightaway! Gave it a few wiggles to ensure it was moving freely and all good. Thanks for the instructions and demo my lads room is all toasty now and as winters drawing that’s a weight off my mind
No problem Adrian.
I was able to sort out this problem in my daughters room in 2 mins after watching this. Nice one my friend, thanks !!!
No problem 👍
Thank you, just sorted my bedroom radiator, it's been cold for months, I thought it was a blockage somewhere, bleeding my radiators didn't work... you've just saved me alot of money! 😊
No problem.
Was freezing my ass off in an old house, during a storm, in the West of Ireland. Five minutes later and I'm toasty warm. I salute you!
No problem Pat.
You are a 1st Star, i've just fixed a rad that hasn't worked in 15 years with a careful tap, tap, tapping on the pin with a very light tacking hammer. What a great video, this is the 2nd tip I have now used of yours. Thanks so much A1*
No problem david have a happy warm Christmas.
Haha, I thought my 8 years in the cold was bad enough!! Mine did take a little more persuasion than yours, I thought it wasn't going to work , and then it did!
Thanks for this - 2 radiators fixed with a hammer. Had tried everything and knew the valve was stuck and wouldn't spring back up, but wasn't sure how 'persuasive' to be until you said the pin wouldn't come out. Many thanks !!!
No problem.
thank you so much fixed in less than five minutes and free. thank you again!!
Radiator valve on my radiator stuck ,room freezing,all other rooms hot,didn’t know what to do.watched this video got my
Pliers out and BINGO worked a treat.thanks so much for the video
No problem Mark.
Thanks - perfect solution! Took the top off. Then with a pair of pliers pulled up the pin, which was stuck down. Pushed and pulled it up and down a few times and now valve is working perfectly.
Happy and Warm New Year!
That`s great, have a happy new year Roy. Al and Jan.
Al just rebalanced all the radiators and unjammed a jammed TRV all wth the help of your easy to follow videos and a trusty hammer, thanks mate :)
No problem.
Fantastic...... Had an old rad that we refurbished and all good except the rad wouldn't warm up. Refilled the rad, checked the combi boiler pressure was ok and then popped on the heating and it still wasn't getting hot. So after watching this tip, a tiny tap with a pin hammer and the pin popped up. Now it's piping hot again. Thanks very much for this tip, you're a gent!
No problem Steve.
spot on. Thanks for posting. This worked a treat on mine. Saved me getting my mate round!
Cheers man worked a treat , That's me King for a day now , Magic
Great video - thanks for sharing! This fix worked on two radiators and our house is much warmer now:) 👍
No problem.
Brilliant video. Arrived at holiday home last night (December!!) Rad not working. Used the sophisticated tool and worked a treat. Having a coffee now, thanks!
No problem.
Watched your video and can finally have a warm room again!
Tried flushing the system and bleeding for ages. Neither worked and clear water just ran through. I wiggled this with pliers and then hammered around the area as you said and it pinged up. Black water then came out and the radiator was hot!
Watched your other video of how to get the TRV off too. Easy quick fix when you know how.
Thank you so much.
No problem Hattie.
You're a top class gent sir! I never realised how easy it was to do this. Just unblocked my lounge rad thanks to you! Merry Christmas!
Happy holidays!
Hi, thank you for your video, I just fixed my stuck valve! However your comment at 1m 50s is incorrect, the pin will come out if pulled with pliers, mine did and gave me a heartattack, nice little fountain from the top of my valve! However I managed to push back in and all working unbelievably, no leak!!! Phew! My advice is to just move up and down with pliers gently, as I could hear the water start to flow into the Rad just before I pulled my pin out! All the best, and thanks for vid!
Save the Jollies Some valves, just a few, do pull out, but most just lift and stay put. I shall put an annotation at that point in the video, saying to just move gently up and down in case the valve is like yours.Al.
Brilliant! Exactly what I needed to fix my daughter's stuck radiator. Thanks very much.
Stuart Hamlin No problem. Al.
Howya Derton, can I just a BIG THANK YOU for your video, for the last three days the bollox was frozen off us he in Co. Roscommon, Ireland. i only got a chance to see your video today and am now nice and warm in the sitting room again after fixing my Rad thanks to you. Merry Christmas.
Good to hear, have a good Christmas too.
Thanks for your excellent video (I have watched some of yours before). My pin would not come up and I was nervous of hitting too hard, so after the hammer failed after the first couple of bashes, I squirted WD40 on to the pin and gave it another bash after a few minutes It worked a treat! Thank you so much as whilst I can tackle most things, plumbing has always been a huge stumbling block for me.
You're welcome! Glad you sorted Ann.
Genius! Just applied your video and now the rad is working. Cheers Al!
No problem.
Desperate Gran here, your videos just helped me, nice and warm now 👌
Glad I could help
Thank you for this video explanation. Your tips worked a treat and the problem of the sticking valve was quickly solved,
Your advice to wiggle the pin loose with plyers fixed my problem in seconds. Thank you sir!
Glad it helped!
Thank you so much! We’ve spent the last couple of months with no heating in the master bedroom and bathroom, the radiators just randomly stopped working and we tried bleeding them but nothing would work. Did this today and now they all work! Thank you thank you THANK YOU!
No problem.
Excellent advice did exactly what Dereton33 said and it worked. This was after I had a local plumber quote £280 to replace the valve to fix the problem for what could only be an hours work.
Great you sorted it ok.
cheers buddy, very helpful, after watching I explained to my wife what she has to do, my Rad works perfectly now, I also got her to check the other rads in the house while she was at it... thanks
Ha ha that`s great.
ahahahahhahahah
Great vid, helped me solve a none working rad in my house (pin stuck down).
Cheers for the help.
+Joe O . No problem.
19 Oct 2022 - amazing thank you. My sons room was cold that he didn't want to sleep in there anymore. That was only radiator that stayed cold. I did what you showed. Heat coming thru radiator now. Thank you so much. Regards, lone struggling mum of one little boy.
Glad it helped! Keep warm.
One of the most useful videos I've watched! Definitely saved me a visit from a plumber.
That`s great.
You just saved me money. Out of 5 radiators, only 2 worked. Turns out the valve was stuck down in each of the the 3 none working ones. They're all working again now thanks.
Excellent!
Thanks a bunch for this video! You just saved me a likely expensive visit from a repairman.
Brilliant thanks so much, sorted my issue straight away! Thank god for people like you taking the time.
No problem.
Thank you so much. I thought I was going to have a hefty repair bill. I was a bit nervous at first but the hammer did the job.
Thanks for that. I had to wait a week last time for the installer to come and replace the faulty thermo and I was cold and very angry having spent a fortune retrofitting my house with hydronic.
Wonderful! Had one radiator that wouldn't heat up. This video cured it. Pulled the pin up with pliers and I can confirm, if you pull it too hard, it does come out! Easily pushes back in though. Cheers 👍
Glad it helped!
Thanks for this! Radiator in spare room sorted quickly in time for family visiting. Been ignoring this for months!
Excellent!
Thank you so much, man! Two of the radiators in my apartment weren't working, this solution fixed them both!
No problem.
You absolute hero! New to DIY and I was racking my brain as to why the radiator had stopped working. Sorted it instantly
Great.
