I’m disabled and also have crippling anxiety and I live with my elderly granny who’s 84 this year in her big old drafty house and have been pulling our hair out over the heating not working. That ended today after watching your clear and concise tutorial on how to fix our system without the need of paying for a call out. We really appreciate your help and wish you all the best, thank you ❤
Being one who records whilst they work and edits in the twilight hours. I know the difficulties and how much effort goes into making these videos. Material like this is undervalued. Education has changed so much with RUclips. Society are gaining the equivalent of a RUclips plumbing degree. It's good when it's used for something positive like making individuals better engineers. Onsite experience is vital as well as real qualifications. Yet this media stream and experience passed on is helping nations strive to better engineering standards. It would have been a game changer if I had some of these videos when initially qualified as a plumber 13 years ago. There was hardly anything like this to watch. It's great that the information is there for those that are thirsty to grow in their knowledge of the trade.
This tutorial was more than useful; it was inspirational. From yesterday morning, I had no hot water or heating. I watched Allen's film and cleared the clutter from around my boiler. I found a little button and, well, I'm a sucker for a little button so I pressed it. Hey pressed-o! Hot water and heating returned as though by magic. Now I feel empowered to bleed. All I need is a bleed screw and I'm away. Thanks, Allen!
Allen, Brilliant mate, you’ve helped me get the bathroom radiator fully working and the bathroom nice and warm for when me dear old mum comes up for Christmas and all it cost me was a bit of time watching your vid, very grateful, thank you Allen. 👍
Thanks Allen, maybe mention that, when there is air in the radiator, water won’t be coming out immediately when the bleed screw is first opened. Instead, we’ll hear the air hiss out of the bleed screw until the air is expelled, then the water comes out. Also, sometimes the hissing sound might reduce and stop before the air is fully expelled from the radiator. This is a sign that there is an excessive amount of air build up in that radiator and the system pressure has been lost during the bleed process, so the system needs to be re-pressurised to continue with the bleed process. Another way of telling if there is air in a radiator is that you might hear water inside gurgling or trickling through the radiator galleries. A full radiator tends to be quiet in operation. Cheers mate... keep ‘em coming...
After hours of trying to bleed the radiator i did it your way and wish i had seen your demo first ,within a minute the rad was working full time ,wish you lived closer and we would certainly be one of your customers.INSPIRATIONAL MANY THANKS FOR SHOWING HOW.
I worked as a plumber in a general hospital full time, started in the early 70's, there was an older part, the original hospital, with had cast iron radiators, they had " automatic air vents " which had a small wooden tapered dowel in them, when there was any air in the rad' it let it seep out, the the wooden tapered dowel expanded when they got wet, and stop the water coming out, they never need replacing, and were over a hundred years old, and no water on the floor, wish I had taken a photo.

Thanks Allen. I'm only here because my Dad was a plumber for some years - qualified in the 1960's - and I like to see the kinds of things he was doing to put food on the table and clothes on our backs. He turned our central heating off some 10 years ago for some reason, sadly was diagnosed with dementia, bless him, and completely forgot how to put it back on!
@Allen Hart so I bled my radiators the other week, did the thing underneath the boiler to get pressure back up to one. Now my heating only comes on once per day for about an hour. Hot water will come on no bother. The little light that says the heating's on doesn't come on. The boiler sounds a bit 'chuggy' when first switched on. Any suggestions please?
Allen Hart what do you do if only the top of the radiator is warn and the bottom is cold heating is on full and you should be able toch the radiator please help
Thank you , young man. I know nothing about the pressure meter. But when i saw you remove the thermo'#valve i knew that i could do the job. Bleed the air. Being an old a***se motor mech (92+) always aware that i could mess up,saw your instruction & immediately understood THANKS Had a new boiler fitted 12 months back ,i thought over expensive (personal recommendation) cant complain £2656.0 for boiler ,fitting +small radiator (Ideal) Just a bill for the total ,no individual price --parts 1 man & his son 1.1/2 days. again thanjk you GH
Fantastic tutorial & so easy to follow. I couldn't get my boys radiator to work but with these simple checks it's now fully working. Thanks Allen your a lifesaver
Mate, I used your tips to cure not one but two tepid radiators in my system, without even touching the bleed key. I switched the boiler off, then all the other radiators. One at a time, I first shut off the lock shield side (making a note of how much of a turn it took), then removed the thermostat and gave a couple of taps on the pin, replaced the thermostat, reopened the lock shield, kept all the other rads off (except the one in the hall, that has no thermostat on it) then checked the boiler pressure, before firing up the heating. When I was satisfied the faulty rad was working, I turned the rest of the rads on to make sure I'd not shifted the problem elsewhere. Then I did the second faulty one the same way. All rads are now working properly again, without any bleeding 🎉
Excellent.....cold radiator, could not understand why, then just before calling the plumber checked the thermostatic valve, as you said in the video the pin can get stuck probably due to hard water. Gave it a little tap and Bingo all sorted. Thankyou so much!
I learned how to do this from an emercency plumber three weeks before XMas. Bleed radiators, go down to basement, build up pressure by turning the tap on and stop just beyond one bar. Rinse and repeat with all radiators in the house. That was a lot of fun. The hard part was locating the pressure gauge under the tank and locating the silver braided pie with a tap that supplies it. Make sure you know where everything is and have the right tools before you start...goes without saying.
Thank you SO much for this! I decided to replace a manual bleed valve with an automatic one yesterday. (What can I say... I'm lazy!) So much air came out, which was replaced with water when I turned the valves back on. Then the boiler was showing F1 which means low pressure fault. The pressure meter was showing 1.8 Bar which should have been OK (though a little on the high side). I found the manual and found out how to add water to the system, so I added a little. The meter didn't move, so I wondered if the needle was stuck. I tapped the meter a few times; nothing happened. The boiler was still showing the fault indication so I added a bit more water and then the pressure gauge sprung into life and started reading 0.4 Bar! It was then functioning, and rising. I added water to take it up to 1.0 Bar as specified in the instructions (should be in range 1.0-1.5 Bar ideally) and the fault indication went away. The radiator that I had worked on started working so much better than I think it ever has! I'm glad I watched this video first!
My boiler was broken down, low pressure and not working on 4th Oct 2020. Call the professional he raised the pressure and did a service. He reset it. It worked for a bit and broken down again. All together they came 5 times replaced 2 parts but never did what you showed us here. He said it is very frustrating not knowing what's wrong. It is now 4 months and checking everyday if it works. I was told to reset every time if it breaks down. Still fingers crossed. Not cheap!
Great tip. I took a photo of my boiler pressure before releasing the radiator air and he's right it dropped by 1 bar. I then had to refill the boiler, before finally turning on the heating again.
Good video. I've got problems with thermostat valves always leaking from around the plastic bit around the pin some are brass .any fix instead of changing it .
hi in your video were you were topping up the water pressure in a boiler by opening the 2 white taps under the boiler? what can you do if the taps are stuck shut? can you take off the plastic taps and use a wrench to open the filler taps quarter of a turn?
Thank you for the video and sharing your experience. A few drops of a silicon oil seem to help to release and get moving a TRV pin or a radiator valve. Perhaps a few drops of silicon oil to this spots could be a part of a year maintenance.
Great video. I used to live in a house that honestly must have just had a completely broken system, as literally every few months you could bleed a radiator, and so much air would gush out. Then afterwards, most of the radiators still wouldn't work. Or some would, but then others would stop working.
Cheers pal I've been trying to bleed rads up stairs for weeks no air coming out just water so I was constantly fill boiler up in the process I noticed the bit in your video about the tapping of the valve so I gave it a try and just like magic the buggers started to get hot thank you so much
I just moved into a home with this type of heating system. The house has been unused/underused for quite sometime. Also, the water is very hard in this region of Spain. As such, when we moved in, we had so much trouble with the heating. As I was not familiar with this form of heating, we had to call a plumber. I wish I had seen this video before calling as much of the work I could have done myself. That said, there were things where the plumbers skill and advice was invaluable. Thanks for this video. It has been huge help.
Very helpful video, thank you! I did it while radiator was off, and the air stopped hissing out eventually, but no water came out - cause for concern? Or should I have done it with the heating turned on?
Wow that wallpaper. I twiddled one of those lock sides once ,thought it might have been turned down a bit, and black water pissed out all up the wall and wouldn't stop regardless of what way I turned it.
Black water may suggest the system inhibitor fluid is non existent or past its best. Could use a magnaflow system to assist with cleaning your water but nothing will keep it perfect
Two of my rooms are located upstairs. The radiators are only getting hot from the the top but Not bottom. I have bleeded all the radiators in the house but it's still same. Could you suggest something ??
Hey if you sort the comments of this video by "Top comments" and scroll down to the 16th comment I think, by Colin Wirral, he mentions what might cause this in his last sentence. Good luck!
thanks Allen, could you do a video on the feed tanks. I don't think mine is feeding correctly as the system won't fill. also I've got two tanks in loft so which is which
Great advice Allen, many thanks 😊.... quick question, ..if one of your radiators is hot at the top, but cold at the bottom, what would be causing that, and is it simple to fix?
Great video. One of my radiators just isnt heating up (downstairs) Lock Shield is fully open and have taken thermostat off other side to check pin. The pipes going up to radiator are hot but noting going into it. Any ideas ?
We've never bled our radiators in 35 years and we've never had a problem with them. Why would you have lock shields on both sides of a radiator? I think we have one like that and it seems to be switched off. I'm not sure how to switch it on.
@@nickpearsonuk Thanks that's very useful to know. Open at all times means 'on at all times' when the heating system is on, doesn't it? What if that radiator has been left individually switched off. (Both locks in the off position). We'd need to 'fiddle with it' then to switch it on, wouldn't we?
I just watched your vid your a gem I bled the rads and checked the valves so fingers crossed I have a solid fuel back boiler and oil some of the rads never work right so I'm hopeful now thank you from a Irish mammy ya know coz we do these jobs ourselves lol
wille williamsson I don’t have oil in water or water in oil but keep getting air in my collant system. Can it still be the head gasket? It runs well for a few hours after bleeding the system but then it builds up pressure and air again. Ford Fiesta 2005 1.4
Hi I have this boiler and put too much water in it and the pressure is too high I watched your other video and can’t tell if I have a filter underneath mine it says magnetic warning on it please help 😅
Really depends on your requirements, for combis I like, Viessmann 100, Ideal Vogue, Ideal Logic, and many more. It’s all about how they are installed really. Thanks.
@@AllenHart999 Thanks for replying Allen. Also it's amazing that you are raising funds for The Candlelighters Trust, I have too, such an important charity. How can i get your details, I'm not too far from Leeds.
hi allen. im an electrician, found your video on splan wiring very useful. some radiators in my house constantly make a clicking noise when the heatings on. ive bled them all and the pressure is good but still have the noise. do you have any idea what could cause that? thanks
Pretty normal - expansion of the rad - forces it to slide on its mounting brackets. New rads come with plastic inserts for the rad to rest on - they creak more quietly !
@steve gale Who said you force things ? You're making things up now ! LOL You also don't seem to have an appreciation for thermal expansion. The difference between a rad that's cold and the same rad that's hot is its length is different. As it sits on at least 2 brackets fixed to a wall that does not expand, something must give - and the design is that the rad slides on the brackets - and when it does, a noise is often created as a creaking sound. It's quite normal !
Very helpful! Thank you. I done blood all my radiators but now the water pressure from the heat side is very very low and not getting warm at all. Pleas advice my hou I can fix that. Thank you 🙏🏻
I could never dare to remove the trv on one of my rads for about 3 years because i thought i would cause a leak and be left with water marks on the adjacent walls and the ceiling below. Even though the trv is on zero, the rad is still piping hot and my son does not like any heat in his bedroom and has to keep the window open due to this issue. Anyway, i took off the trv and unstuck the pin as you demonstrated in your video and now the rad turns off as it should when zero is selected. So thank you very much for sharing this and you saved me a bunch of money.
Allen Hart what do you do if only the top of the radiator is warn and the bottom is cold heating is on full and you should be able toch the radiator please help
hello sir when you install a thermostat into the radiator it can put it in the bottom side or in the uppper side in my house they put it all in the upper side i saw your demo it is in the upper side what is the differince between the two side or may i say what is the standard process sir thanks
I would have thought the advise would be to listen for a hissing or spluttering sound as the bleed valve was opened which would indicate air was present in the radiator. When the hissing/spluttering sound stopped and only water was coming out then close the valve 🤷♂️
Hi, hope you can help. Had a new boiler fitted in June. Obviously didn’t nee the heating on until recently. Only to discover 3 x radiators upstairs no longer heat up. The 3 in question at all in line with each other. Called boiler company, guy came our. Said we had a blockage in the middle one. Advised to change it. So I did, fitted a brand new one and still the same. So I ended up changing the other 2 aswell as they were old. The en-suite towel radiator used to be piping hot. Now it stone cold. Mildly warm inlet pipe but that’s it. Middle radiator is the same. The end radiator is now heating up. Quite warm bit not so much that you’d scald your hand like before. I’ve tried back flushing by connecting a hose into one side of copper pipe from the end that improved and opening one from towel radiator then the other. Initially got some dirty water but sadly the system had not improved. All the other radiators in the house are piping hot. So I’m stumped, please help.
Out of all the adverts that crop up, the oceans of spam and misleading content, clickbait and scams... This one stands as a glowing beacon, untainted and pure among all the waste. Praise be, and may your radiators bleed safely evermore.
Hi Allen thanks for your video but funny enough, I increased the pressure on my boiler but the radiators would still not come up. What could be the problem?
If you have an unvented cylinder (open vented system with tank in loft, not closed). Do you need to follow the procedure to re-pressurise the hot water tank after a bleed of all the radiators ?
great explanation mate before watch you i thought i had to remove water from my radiator so by mistake i filled a 50cl bottle of water from the water of my radiator. is there a problem with this. ?
I've got a two-family house I bleed all convectors bottom and second floor but it seems that on the second floor I can't keep the kitchen and liver room convector hot.I check the shut-off valves they are ok.I bleed both convectors until they got hot. Then my tenants call me the next day saying they gotten cold again. What's the problem?
Hi Allen, I always enjoy your content. You mention balancing the system. Why don’t you do one, in your own style? I’m sure a lot of people would find it very useful.
A couple of points, never use gland pliers to tighten or loosen valves they will round off the shafts, new valves then. The white portion of the bleed valve will spin round even when the valve is closed, this is to direct the water coming out. Again do not use gland pliers, use a proper spanner or adjustable. Do not hit the pin of the TRV valve too hard otherwise the top portion will not locate properly again..if the rad is cold at the bottom, the rad is loaded with sludge, needs draining and inhibitor added..
I watched this video and others but it didn't solve my problem of no heat getting into radiator. So I removed the trv, found the pin jammed down so loosened it and, hey, heat began to flow into the rad. I replaced the trv and heat stopped. Upon inspection of the trv I found the internal plate was stuck down so I drilled out the centre of the plate so the pin could stick through it and..presto... I replaced the trv head (now cosmetic only) and no more problems. I hope this tip is useful.
This video is great... thank you! I'm always afraid to bleed the radiator in case I mess it up 😮 Can you please come around to my house and do it for me 😁
Hi Allen, I thought you were quite brave trying to pull that pin out the trv, if it came out, surely you would have 1 bar of pressure behind it if it were pressurised? Great vid btw
I’m disabled and also have crippling anxiety and I live with my elderly granny who’s 84 this year in her big old drafty house and have been pulling our hair out over the heating not working.

Then afterwards, most of the radiators still wouldn't work. Or some would, but then others would stop working.
Brilliant video, so much more detailed than most on RUclips. Cheers Allen.
Thank you so much.

Thank you for your video. So the boiler HAS to be off when you bleed the radiators?? I didn't realise that, I was clearly about to make a big mistake.
Glad it helped
I've always bled Radiators with the Boiler and heating ON - and Radiators hot????

Mate brilliant. RUclips random recommendation but you just helped me fix my thermostatic valve. No more freezing kitchen!
theokr89 That’s brilliant. Amazing what they know about us these days.
Cheers pal I've been trying to bleed rads up stairs for weeks no air coming out just water so I was constantly fill boiler up in the process I noticed the bit in your video about the tapping of the valve so I gave it a try and just like magic the buggers started to get hot thank you so much
I just moved into a home with this type of heating system. The house has been unused/underused for quite sometime. Also, the water is very hard in this region of Spain. As such, when we moved in, we had so much trouble with the heating. As I was not familiar with this form of heating, we had to call a plumber. I wish I had seen this video before calling as much of the work I could have done myself. That said, there were things where the plumbers skill and advice was invaluable. Thanks for this video. It has been huge help.
I couldn’t get past the wallpaper. Was this something about radiators?

Lol me too,I was thinking id like curtains in this pattern for one of the bedrooms or kids den.
Very helpful video, thank you! I did it while radiator was off, and the air stopped hissing out eventually, but no water came out - cause for concern? Or should I have done it with the heating turned on?
Thank you so much.
Sounds as though the system pressure dropped too low while you were letting the air out. Re-pressurise your system to 1 bar & try bleeding again.

Wow that wallpaper. I twiddled one of those lock sides once ,thought it might have been turned down a bit, and black water pissed out all up the wall and wouldn't stop regardless of what way I turned it.
My wallpaper is ace lol
Black water may suggest the system inhibitor fluid is non existent or past its best. Could use a magnaflow system to assist with cleaning your water but nothing will keep it perfect

Two of my rooms are located upstairs. The radiators are only getting hot from the the top but Not bottom. I have bleeded all the radiators in the house but it's still same. Could you suggest something ??
Hey if you sort the comments of this video by "Top comments" and scroll down to the 16th comment I think, by
Colin Wirral, he mentions what might cause this in his last sentence. Good luck!
thanks Allen, could you do a video on the feed tanks. I don't think mine is feeding correctly as the system won't fill. also I've got two tanks in loft so which is which
Great advice Allen, many thanks 😊.... quick question, ..if one of your radiators is hot at the top, but cold at the bottom, what would be causing that, and is it simple to fix?

You mentioned that incorrect radiator bleeding can cause the boiler to bang and clang but can you explain what causes that and what you must not do?
No water in boiler could be one reason, Air locks, etc.

Great video.
One of my radiators just isnt heating up (downstairs)
Lock Shield is fully open and have taken thermostat off other side to check pin. The pipes going up to radiator are hot but noting going into it. Any ideas ?
We've never bled our radiators in 35 years and we've never had a problem with them. Why would you have lock shields on both sides of a radiator? I think we have one like that and it seems to be switched off. I'm not sure how to switch it on.
Interesting
Thanks very much for your comment, please consider subscribing to support the channel 🙂
One radiator in the system needs to be open at all times so never has a TRV on it and usually has two capped valves to deter people from fiddling.
@@nickpearsonuk Thanks that's very useful to know. Open at all times means 'on at all times' when the heating system is on, doesn't it? What if that radiator has been left individually switched off. (Both locks in the off position). We'd need to 'fiddle with it' then to switch it on, wouldn't we?
your channel's a blessing! just bled my radiators for the first time in years! thank you! :)

I don’t have oil in water or water in oil but keep getting air in my collant system. Can it still be the head gasket? It runs well for a few hours after bleeding the system but then it builds up pressure and air again.

What boilers would you recommend Allen.
Really depends on your requirements, for combis I like, Viessmann 100, Ideal Vogue, Ideal Logic, and many more. It’s all about how they are installed really. Thanks.

Also it's amazing that you are raising funds for The Candlelighters Trust, I have too, such an important charity.

hi allen. im an electrician, found your video on splan wiring very useful.
some radiators in my house constantly make a clicking noise when the heatings on. ive bled them all and the pressure is good but still have the noise. do you have any idea what could cause that? thanks
Mine do that in my house. Expansion of pipes normally.
You could check the brackets that the panel hangs on and make sure they have a nylon clip on all the hanging points,
Pretty normal - expansion of the rad - forces it to slide on its mounting brackets. New rads come with plastic inserts for the rad to rest on - they creak more quietly !
@steve gale You prefer them to bend the brackets and pipes then eh ?
@steve gale Who said you force things ? You're making things up now ! LOL You also don't seem to have an appreciation for thermal expansion. The difference between a rad that's cold and the same rad that's hot is its length is different. As it sits on at least 2 brackets fixed to a wall that does not expand, something must give - and the design is that the rad slides on the brackets - and when it does, a noise is often created as a creaking sound. It's quite normal !
Absolutely spot on mate. Never had to do it before, straight to the point and very informative. 👍
Happy New Year

How many times can you say the word “radiator” in 9 minutes?
Michael Porter Perhaps he’s on radiator commission.
He doesn’t say radiator he says Ray-de-Ater!!
That’s a great idea 😂
At least he doesn’t call them rads

I could never dare to remove the trv on one of my rads for about 3 years because i thought i would cause a leak and be left with water marks on the adjacent walls and the ceiling below.
Even though the trv is on zero, the rad is still piping hot and my son does not like any heat in his bedroom and has to keep the window open due to this issue.
Anyway, i took off the trv and unstuck the pin as you demonstrated in your video and now the rad turns off as it should when zero is selected.
So thank you very much for sharing this and you saved me a bunch of money.
Thank you so much for watching.

hello sir when you install a thermostat into the radiator it can put it in the bottom side or in the uppper side in my house they put it all in the upper side i saw your demo it is in the upper side what is the differince between the two side or may i say what is the standard process sir thanks
Thank you so much.
Thanks very much for your comment, please consider subscribing to support the channel 🙂
I would have thought the advise would be to listen for a hissing or spluttering sound as the bleed valve was opened which would indicate air was present in the radiator. When the hissing/spluttering sound stopped and only water was coming out then close the valve 🤷♂️

Hi, hope you can help.
Had a new boiler fitted in June. Obviously didn’t nee the heating on until recently.
Only to discover 3 x radiators upstairs no longer heat up. The 3 in question at all in line with each other.
Called boiler company, guy came our. Said we had a blockage in the middle one. Advised to change it.
So I did, fitted a brand new one and still the same. So I ended up changing the other 2 aswell as they were old.
The en-suite towel radiator used to be piping hot. Now it stone cold. Mildly warm inlet pipe but that’s it.
Middle radiator is the same.
The end radiator is now heating up. Quite warm bit not so much that you’d scald your hand like before.
I’ve tried back flushing by connecting a hose into one side of copper pipe from the end that improved and opening one from towel radiator then the other.
Initially got some dirty water but sadly the system had not improved.
All the other radiators in the house are piping hot.
So I’m stumped, please help.
ask you installer to come back and help you. Happy New Year
I have I guess double radiators that have 2 bleed points , do i need to do both or just the one
Thanks very much for your comment, please consider subscribing to support the channel 🙂
Bleed them both. Thanks.
Out of all the adverts that crop up, the oceans of spam and misleading content, clickbait and scams... This one stands as a glowing beacon, untainted and pure among all the waste. Praise be, and may your radiators bleed safely evermore.

Hi Allen thanks for your video but funny enough, I increased the pressure on my boiler but the radiators would still not come up. What could be the problem?
Thanks very much for your comment, please consider subscribing to support the channel 🙂
If you have an unvented cylinder (open vented system with tank in loft, not closed). Do you need to follow the procedure to re-pressurise the hot water tank after a bleed of all the radiators ?
Very useful video, learned several things from it even though I've fitted radiators before.
Thanks for the clear guidance.

great explanation mate before watch you i thought i had to remove water from my radiator so by mistake i filled a 50cl bottle of water from the water of my radiator. is there a problem with this. ?

Hi Dear all ,
Need your advice Baxi Boiler 105 can fit how many radiator maximum thanks
It depends on the pipework really, Not really a maximum if it’s piped correctly. Thanks.
So you turn off the boiler . . . But is the radiator hot or cold? It looked cold . . Does it bleed if cold?
Doesn’t really matter if the water is warm or cold when bleeding. Thanks.

I've got a two-family house I bleed all convectors bottom and second
floor but it seems that on the second floor I can't keep the kitchen and
liver room convector hot.I check the shut-off valves they are ok.I
bleed both convectors until they got hot. Then my tenants call me the
next day saying they gotten cold again. What's the problem?
Probably needs balancing
Thank you so much.
Thanks very much for your comment, please consider subscribing to support the channel 🙂
Hi Allen, I always enjoy your content.
You mention balancing the system.
Why don’t you do one, in your own style?
I’m sure a lot of people would find it very useful.
I might do one. Thanks.
Good idea. I'd like to know how to balance radiators properly too.
Yeah Al, balancing video. It's regularly omitted by us diy-ers but could be overlooked as another fault with "cooler than other" rads in the system
Thanks very much for your comment, please consider subscribing to support the channel 🙂
A couple of points, never use gland pliers to tighten or loosen valves they will round off the shafts, new valves then. The white portion of the bleed valve will spin round even when the valve is closed, this is to direct the water coming out. Again do not use gland pliers, use a proper spanner or adjustable. Do not hit the pin of the TRV valve too hard otherwise the top portion will not locate properly again..if the rad is cold at the bottom, the rad is loaded with sludge, needs draining and inhibitor added..

I watched this video and others but it didn't solve my problem of no heat getting into radiator. So I removed the trv, found the pin jammed down so loosened it and, hey, heat began to flow into the rad. I replaced the trv and heat stopped. Upon inspection of the trv I found the internal plate was stuck down so I drilled out the centre of the plate so the pin could stick through it and..presto... I replaced the trv head (now cosmetic only) and no more problems. I hope this tip is useful.

Hi Allen, I thought you were quite brave trying to pull that pin out the trv, if it came out, surely you would have 1 bar of pressure behind it if it were pressurised? Great vid btw

You are better to turn it off really and then top it up before to turn it back on again. Thanks.
