HOW RADIATOR VALVES WORK AND HOW TO SET THEM - TRV/Thermostatic
HTML-код
- Опубликовано: 18 янв 2019
- How radiator valves work and how to set them. TRV's or Thermostatic Radiator Valves have numbers on the sides that correlate to the temperature in the room...not the temperature in the radiator. In this video explanation, I demonstrate this common misconception. Show this to any family member who keeps playing with the radiator valves. Properly explained!

Fantastic video. Should be compulsory viewing for all UK Home owners.
I was today years old when I figured out how my thermostat (TRV) worked. Thanks for the great explanation!
I’ve always had a understanding how it works roughly but this really set it in stone and it’s great looking how it actually does it’s job for better understanding. Thank you James 🙂
even knowing how the valve works it's still awesome to see the valve work in action, watching the flow of water slow down till it stops as you are heating it up is very cool. love your videos, as i have just finished learning beside a plumber and now on my way to work solo, your videos are very useful.
This fella is bang on, explains things so easily, which I've just shown a Tennant an she understood straight away
We're an agency and this is such a helpful video to share with our tenants, (especially those in house shares). Keep the basic knowledge videos coming please!
Thank you, very informative. Need more videos like this. All Gas controls, safety shut offs, etc. Keep up the good work.
Hi James - Just wanted to say a huge thank you for all the plumbing videos. We've had a bit of an autumnus horribilis this year with plumbing problems, and the fact that I am now sitting in a warm house with hot, balanced, airlock-free, inhibitor-filled radiators (and correctly set TRVs!) is largely down to you. Good job... Thanks.
Awww cheers!
That's great. Now do a tutorial on how the indicator lights on a car work and how to activate them. This will benefit many drivers.
Oi! You're not referring predominantly about women drivers are ya? You sexist, misogynistic, patriarchal oppressor! If you are, can I join your club. ;-) LOL!
Even the most obstinate woman will still try and argue that you have got it all wrong. Even though you fitted the new boiler and removed the manipulative wheelhead valves for fitting trv's, they'll still ramp 'em up to max.
Worse still, they will dial down the target temperature of the heating flow at the boiler, (on days when there's a 2 foot covering of snow outside) so that the heat exchanger gas modulates down or turns off entirely. The boiler will continue to cycle..on, off..on, off/ fire up-> modulate down-> go off-> fire up-> mod down- go off ad infinitum, which is not efficient at all. Then, with their next breath they'll boom, "turn that light off, we're not made of bloody money!" Like some modern day version of Air Raid Warden Hodges from Dad's Army, but with female logic, on speed and with pre-menstrual tension.
Aaaargh! (Loafer)---------------------> pub!
As a BMW driver, I refuse to learn how indicator lights are. Tyvm.
Learning to use indicators will help *pedestrians* too.
I am sick and tired of how many drivers only bother to use indicators when they see other cars on the road, when people crossing the road (and cyclists too) are looking not just for the presence of cars, but also looking at the indicators to know where they are going.
Indicators aren't just there for other motor vehicles. *Always* use them.
One of the most useful videos I've seen so far. Great presentation👏🏼

How can I balance a new radiator system after installation
Can you do a mechanical Analog TRV vs digital TRV (ie Hive) and response times
Hello mate so I'm beginning to see what my problem is with my radior valve in my room from watching this video. Basically I live in shared flat and there's a radiator in each room. When I ever my heat is on it is ridiculously hot so I always turn the thermostat down in the hall way but flatmates who live upstairs get angry and come down and turn i it back up cause obv they're prob colder up stairs.
So I've been wondering why when I turn the valve on the radiator in my room that it doesnt turn the heat down. From what you mentioned in this video stating "if you go into a room and the room is roasting hot and the radiator is roasting hot, turn the trv down" . I've been turning it down and it does nothing so I'm guessing the sensor is broken right? Need to buy a new one?
@@ddono9024 Yes or you may need to take it off, give it a clean and make sure the pin on the TRV moves freely and re-seat the head, might be that the pin is stuck open and not regulating the water flow.
I have watched a lof of your videos over the years since buying my house. Always fantastic and clear explanations which are really helpful. Cheers mate. Legend
Dude anothet great stuff. Thanks to your videos I moved radiator across the room, installed exposed shower and now understood why my rads are cold on 3 when the room temp is 23. Keep up like this. You are making life easier.
Really Simple and concise way of explaining how TRV works. Well done
Great video James, your informal style makes learning fun and demystifies the world of plumbing. Yes please more videos on plumbing basics
Will do guys!
You are a natural teacher! Really good presentation. Thank you 😊
Your Videos have been invaluable, and gave me the confidence to do some necessary housekeeping on my system. I have found a few tricks, that if you think are sensible to make videos on, would be appreciated: Tip/Vid 1: To find the last RAD, (Which you will drain from), open all Lock Sheer valves and TRV's fully, including downstairs, heat the system up for a 1 hour or so, and the last Rad should be cold. I found this out btw after I had done my work, but doing it before will help I think. I labeled it "Last Rad". Tip/Vid 2: When replacing a 3 port valve, always set the old valve you are replacing to "M" this will make sure you take the top water from the cylinder out of the system when you drain. Use some LS-X silicone around the original olive when replacing, I left it 12 hours to cure , so wrap up warm! and so far...after refilling (touch wood) no leaks. Tip/Vid 3: After you have refilled the system, and you have bleed from downstairs to up, worth advising if you are cleansing the system first before inhibiting, is to close the last RAD valve before refilling contrary to your advice , then follow the bleed process.... that way you don't loose the cleaner. It meant more bleeding, but I'm confident it's in the system for a few weeks before I do the whole process again to then add inhibitor. Lastly add to that, keep the ball cock open in the header tank, as if that drops significantly whilst your bleeding air, you will suck more air in, I heard it filling all the time, but was paranoid about the level going too low. Anyway thanks again for your vids.... they are amazing and will subscribe...I'm no plumber!! but there is NO WAY I would of done this task with out your great vids !!!..
These are the videos I like the most: entertaining and everything explained in plain English. Well done for a splendid effort.
Hi James, that's really well explained. I have spent so many hours explaining this to clients over the years. I'll send them here from now on. 👍🏼👍🏼👍🏼
Just had new valves fitted so finding this video is quite pertinent. Probably like most people I didn't realise that is how they work, so thank you for the explanation. I will be trying my new valves out with all this in mind!
At last, a thorough explanation of a TRV. Won't forget that now. Thanks.
Thank you, very informative. Did not have a clue to use these valves in the past but now I do. Thank you so much.
One of the best explanation I have ever seen. Well played James
Cheers smart tech brudder!
A master class. I have had the same gauge installed on my steam radiator without understanding how it works. Thank you. Seattle.
This is an excellent demo. I'll show this to my family if they ask.
Great stuff. I've made it to nearly fifty without really understanding how a radiator works. My eyes have been opened, thanks PP :)
Hey James. Thank you. I really appreciate this. Well done on a crystal clear explanation.
Brilliant...the amount of times I have to explain to a customer how a trv works!!!
This is a brilliant and well explained ... even a simpleton like me can follow this.
Speaking of, I followed his guide and my gas meter is now running down slower.
That’s really well explained and well presented, I think we’re all a little wiser, excellent 👍
Thanks guys!
@ThePhilandPam.. You two keep popping up in various comments sections of other content creators to whom I subscribe. Just curious as to why? I've got an excuse.. I'm just trolling James. He doesn't dunk his bourbon cremes until ultimate crumble-point.
loafer sheffield Hi loafer I hadn’t really thought about it like that, I think we always pop up between projects when we can get a bit done on videos and can catch up with everyone we follow and everything that’s going on RUclips. We’re just waiting on this last project going through at the moment, it always feels like ages and we can’t move on anything new until it completes 😀👍
No it wasn't - he was forever fiddling with it - precisely opposite the point of the video !
Thanks it was really helpful
Thank you very much for this lovely video and the demonstration. It was very helpful for me to understand TRV and how the valve work.
Well done James as you have great demonstration about how TRV's are working.
1:40 in and the question has already been answered for me. In all my years I've never known how TRV's worked, Thanks!
Most useful thing I’ve learned for ages. Thanks
Wow, what a lesson! You're a good man J.
That was excellent, thank you.
I've never really understood plumbing paraphernalia, that's why I run an Electrical contracting company.
Most useful video I've seen in ages. Didn't realise they worked like that. Makes far more sense now. Thanks
Got the honeywell smart ones recently, amazing system. Nice explanation - I've sent it to my Dad!
Brilliant demo James, and close to my heart. So many switch between 5 when they are cold and back to 0 when they get too hot! This should be part of the National Curriculum!
True
Been obsessing over my heating as i've recently gone from an old back boiler system, where I would just set times for it to come on and heating would be on full the entire time. It's really made me think about how I use(d) the heating. This video clearly explained what a ridiculous amount of articles i've read, failed to. I'll readily admit I had no idea, which over the years has cost me hundreds.
i think you made it so easy for every body great explanation loved the video.
Thanks!
Very clear and straight to the point; well done.
Great video! Turned out that I was setting it up wrong after all!! Thanks for that great video, really illustrated how does a TRV work!
Nice work. It always surprises me, how few people understand how a thermostat works.
Thank you SO much! Exactly what I was after and more! Also helped with my fear of plumbing too, to see what is actually going on.
I absolutely love these types of videos James. I’m a mechanical engineer so love stuff like this.
And yes loved live and kicking ANNNND nightmare. My era too.
I will hold my hands up and say I didn't know this!!! Great vid! Keep up the good work!
Another great video. I love the quality of your camera and what all you are doing!!!
Thanks dude! It's good to see what you guys get up to in the states!
Great info, thanks for the full explanation I learned something here... Also its great to see Bradley Cooper taking time out from filming for this. :)
As always very informative & entertaining - well done!
Thank you James! Bathroom sales designer here and I feel called out (as the person who just can't get this knowledge into my head). The more I learn the more questions I ask. Thanks for explaining how it works! I often get customer who ask how the thermostat works and until now I could not answer any of them.
This helped me to understand a lot more thanks bro!
Excellent video - should save a fortune this winter.
I’ve only just found your channel 👍🏻 it’s good to find this information explained probably.. in uk English.. so now I’m gonna go binge watch on your uploads, learn a few tricks and understand things I wasn’t sure off..👍🏻 great stuff
Thank you pal that’s a fantastic video really well explained , thanks for taking the time 👍👌
Great video mate! Spot on with informing family 😤😂
Good to hear from you again and thanks
Mind. Blown. Great video, well explained. Thanks! 👍🏻
Really appreciate this video - just moved to a new house and couldn't work out why the upstairs was so much warmer than the downstairs - just thought it was a case of the boiler being upstairs and the upstairs radiators being serviced first and the downstairs radiators being serviced last with cooler water lol
Thanks. Good demonstration and explanation for the lay-person. Phew. So simple when you know :)
Thank you! Great and fun instructions. Very useful!
I stumbled across this and I’m glad I did. I now have all my valves set at 3.5 and the system runs great 👍
Brilliant video! Great demo equipment setup
Great video mate! Would welcome more of these.
Hi James.Just brilliant as usual.
Very well demonstrated and professionally
Absolutely brilliant, mate! A video like this should be a link to on the front page of the manual for every bloody central heating system in the world.
Cheers!
Absolutely brilliant. Many thanks. 👏
Thanks, knowing this makes me relax 3:00 in the morning. I just sleep in a new house and having nightmare because of radiator acting weird. 👍
Absolutely brilliant video, I never new that’s what the dial meant, I always put mine on max thinking it was to give max heat temperature, Now I no exactly how they work
Great demo video of the TRV.
HOLD TIGHT. 👍
Thanks K!
Good vid. My granddaughter's thermo valve is behind her bed. Now I know why the rad didn't work to good.
Good explanation of trv's thank you.
I have said it before, and I will say it again, THIS GENTLEMAN IS BRILLIANT ! He has a great personality and surely there could be room for a television slot for him featuring practical plumbing for dopes like me ! Thanks again for a great informative video. 😁👍
Thanks very much that was Exceptionally well done.Well thought out and well presented.
After having a new boiler and trv fitted I couldn't think why one of my radiators was off all the time (in the room where the gas fire is always on). Now I know, and I can manage it properly. Thanks 👍🏻
well explained thank you
I've been a fan of your videos for a few years now, always entertaining, informative and educational. Then in this one, out of nowhere you mention Knightmare, my favourite tv show ever from my childhood? Well you sir have just ascended to another level of awesomeness!
Brill explanation and demo of how these work Thanks
Excellent explanation James , George is a star ! :o)
Thanks for that,really well explained and great demo. So for most people set your TRV on 3 and leave it be.
luv the way you put things across bud, great tutilage i have learnt something else today, we dont do many radiator systems in New Zealand dont ask why i cant awnser that, but if i come across one i am an expert.
Absolutely loved this and will show the wife !! - especially the bit when you said "it knows the room's cold !" - leave it alone to do its job - does my 'ead in too !!
Excellent description n thank you.
Very informative, thank you 👍
Great video. Even though we don't have radiators in Australia, I still love watching these "rad" radiator vids
Haha! Thanks man...hope you check out my latest TimesWithJames
That's a brilliant explanation thanks
Great video. For the nerdy types a clock in the background would make it even better.
Great explanation on how TRVs work, now all I need is TRVs on my radiators.
Absolutely brilliant! Thank you
Gorgeous. Thank you!
Absolutely brilliant!
Well done mate thank you for teaching us something so many years I've been in building and have never had anybody telling us how this bloody thing works well done thank you very much carry on with the good work and all the best say hello to George
Cos it's a BIG mystery as to why people don't understand them yet seem fine using one to adjust their shower temperature !
Very very knowledgeable and eye-opening video.
Glad you think so!
Nice one mate the amount of times ive spoken to customer's about this my head could blow off with my own heat.
Thank you for this. I had no idea. The plumber never mentioned it.
wow, I had no idea and my Gas Safe Engineer had no idea. He tried "balancing" the system by turning down the TRV, not the other valve. Thanks man!!!
@@stephen3654 Nope.
great video. you should have also shown how the plunger/pin on the valve works and that it can get stuck and how to free it up.
I've just moved from a freezing cold flat to a house that actually stays warm and was wondering why the radiators weren't heating up clearly the rooms are warm enough and don't need to be on.
This is explained perfectly now I understand completely
Great video mate keep up the good work thankyou
