OMG, Thank you! My husband was an amazing heating engineer, but he died 3 years ago and I find myself in tears when I have issues like this. But I followed your instructions, and although I certainly couldn’t of done anything technical, I got it sorted but lifting the trv pin up. Thank you so much!!!

Thank you. 12 years after this is still blessing lives.

Much appreciation Plumberparts! Due to Covid my wife had to work from from home. But the radiator was not working in her room. After lots of complaints, I followed your advice. I had a problem with the TRV pin, and thanks to your tip of gently knocking the side, the pin opened up! I now have a radiator that works, and a happy wife!

Can't thank you enough. Superb clear instructive video.
Flow and return pipes both cold on one radiator - followed your instructions - opened up lock-shield valve fully - nothing! Still cold. I then turned my attention to the TRV (Siemens) and removed it. The 'pin' (bit sticking up) wouldn't move at all, wasn't sure how far it was supposed to be sticking up. Sprayed some WD40 on it and left it whilst I went to have another look at your video in case I wasn't doing it right. A few minutes later when I returned to the rad - Whoopee!! It was already hot, and the pin was noticeably sticking up further, and I was able to push it down and see that it was free. So thank you so much - you're an absolute star!! have subscribed to your site so that I can return if I need any info another time.

I've never commented on a YouTube video before, but this video was so helpful. I'm an absolute DIY novice but I felt like a total pro being able to take apart and fix one of our radiators that wouldn't heat. Thanks for saving me a call to the plumber!

Thanks a million for posting this all of 9 years ago! I was looking at guides to try and troubleshoot my cold radiator and NONE of them mentioned a TRV. Anyway, followed your guide and I have a hot radiator. Many thanks!

Straight to the point! You didn’t spend ages talking about the reasons why it could be. Went straight it in to the possible fixes. After spending a minute or so on why someone is searching. Perfect! And thank you so much.

Our bedroom rad hasn't worked for a year. Took off the TRV, wiggled the thin pin and it popped up a touch. Pressed it down a few times, making sure it was loose. Put the heating on and the rad came warm!! All thanks to you - much appreciated!

Ahh he is adorable.. love it when he turns to talk to himself in the mirror. I am at this very minute following his instructions. A million thanks for such a clear amazing video

Brilliant, thank you so much! My 1 year old’s room was the only radiator that wasn’t working, now it does thanks to following your advice. My issue was the stuck down pin in the valve. Thanks again!!

[nikkik]

Thanks, our radiator issue was solved by the lockshield tip. After having tried everything else 2 years ago, we completely failed to think of messing with the lockshield and have used an electric radiator over winter in that room since then. I followed the instructions to open up the lockshield, and hey presto, a hot radiator :D :D :D

[rpants]

Thank you for posting this. It has just solved my own issue of one radiator not working. Now its toasty hot. You guys don't need to use your own time doing these videos but I just want to say how much people appreciate and value them. My bedroom is now warm!

[DebHarris]

Thank you so much for making this video! Your instructions are extremely clear and easy to follow. After watching this I managed to fix two radiators.

[jeremychurchill]

Brilliant video, thanks! We've just fixed a sticking valve pin on a Danfoss TRV - exactly as you described. Saved ourselves the callout fee and all the aggro of getting a plumber out (we live in the country and these things take time . . .). Have just watched the balancing video as well and - for the first time - actually begin to understand how the system works! Highly recommended!!

[carlychelle]

[norwichcanary]

I can’t tell you how grateful I am for this. A very clear, easy to follow description. Many thanks.
