Your advice was spot on! We'd had new, larger and extra radiators installed recently during a refurbishment. I turned all the radiators off, then on 1/4 of a turn at the valve (rather than the temperature valve) and opened the cold radiator to full. Turned the heating on and now the radiator is red hot, as are they ALL! Thanks again.
You are a life saver! This worked, my upstairs radiator was ice cold compared to the downstairs boiling hot. Turns out the system was unbalanced because i had to drain the whole system to replace the bleeder valve screws. Thank you!
Removed an old radiator and replaced with new one & moved it to opposite side of room - had to extend pipework by 4 metres to new position. Refilled system and bled all radiators. New radiator clold / luke warm and would not heat up. Was about to call plumber in but followed your instructions instead. It WORKED PERFECTLY. All radiators are now balanced and the new radiator in lounge is hot and cosy .... Thank you for posting this video ... saved me a lot of hassle & expense ..... SUBSCRIBED 👍👍👍
IT WORKED! Balancing the boiler/radiator actually worked and now I can sit in my new loft room without a cold nose and hands! Cannot thank you enough! My plumber had no idea how to solve the problem and I did it with your help.
Thank you so much for taking the time to make these videos. You helped me to successfully replace my cistern pump earlier this year and you've just mended my radiators after a week of being freezing cold and sick with worry about there being a huge, expensive problem with the central heating! Thank you so much and all the very best :) x
Brilliant. You saved me. I tried everything after taking my rad off the wall for decorating. Turning all the radiators off made it come back to life. All working now. Thank you
Thank you. Been struggling with this problem, had plumbers in and electricians thinking it was a electric fault. Hundreds could of been save if I seen this first. Good luck and thanks again
Fantastic!!! I tried everything before coming across your video!! Now the rad is super hot and I've opened the rest half a turn and it's still beaming with heat!!! Thank You So MUCH!!!
My problem is the other way around lol my downstairs radiators are boiling but all upstairs aren’t working I tried turning off the downstairs radiators to force heat to upstairs but it didn’t work. The heating system is only a few months old gas
Good advice. I had a cold radiator on my landing, it's been a problem for years. I turned the heating on then went round shutting off each radiator. As I shut off the last radiator before the cold one there was the sound of air moving and the cold radiator started to get hot. It still gets hot a year since the treatment. Thanks for your help.
It`s ok it does not matter which side you shut down the effect will be the same.For info,the lockshield cap that fits on one of the valves when they were new was designed to be adjusted to balance the system then when the cap was reffited that radiator would be in balance with the rest of the radiators without stealing too much heat. Hope that makes sense,regards al.
Thank you so much for this! I had given up on this and had 2 very cold rooms literally for years! i feel like a right eejit! Wish I could buy you beer!
Just tried this and it worked a treat to get heat back into my kids bedroom after getting a new radiator installed in the downstairs bathroom,thank you very much for making this video to help others.you my friend are a star👍
Thank you. Even after bleeding i had 1 cold rad. Shut all the valves off apart from this one as you suggested and the problem rad is now boiling hot! Thanks for the tips and sharing your knowledge.
Great video. Was confused after bleeding the radiators and still no fix to the problem. Followed this and rebalanced the system, and it's working great now! Thanks very much!!!
We’ve had lots of plumbing done recently, just added the last rad and it wouldn’t heat up along with one other, the rest were roasting and I’d bled them all. Tried turning the others off as you suggested and hey presto they’re red hot now. Thank you and happy Christmas!!
I recently bled all the radiators in my house and I couldn't figure out why there was one (1) radiator that wasn't getting hot. I followed the instructions you provided and fixed the problem. Thank you for sharing your knowledge. N.Y.
Had the council out who did this technique to get my last rad on the system (downstairs bathroom no heat at all despite bleeding). Which worked. He showed me what to do etc incase it happened again. The next day though, same again, back to no heat !!! I've been at it hours, rads off heating on etc.... once off though and it's back to cold and will not re-heat.... Left it a few days and complained.... Been trying again this evening to no avail, watched a couple of vids, none helped. Came across yours, and you mention 1 point no-one else did, nor did the bloody council worker do !!! Balancing the system !!! half turns on the rads when turning back on, and balance out so the pump is hitting the last one quicker.... Jesus, the difference it's made....!!! My boiler was kicking in every 5 minutes... It's not kicked back in for at least 20 now. The rads are so much hotter it's untrue, and more importantly, all working and getting hot together, quicker.... Thanks man, Great vids (watched another too) !!!
Thank you. I moved to a new house n the heating in the lounge didn't work, tried bled all valves n been fiddling around with no luck. Tried ur method n switching off all upstairs radiators n only leave the lounge ones on. They all warm now. Thank you very much.
Thank you so much! I have been struggling getting heat into our lounge for literally months. Twenty minutes and you have solved us a massive problem. All our lockshields were wide open. Now sorted and ALL radiators are hotter than they were. Again, thank you so much.
Thanks for your help. I called a plumber, but he failed to show. After listening to your advise about balancing radiators, I set to work. System works well now, thank you
Thank you , I too had given up on a couple of radiators after removing them and flushing, but by turning off all the radiators but the furtherest one, and working backwards as you explain, I have my closest radiator burning hot on an eighth of a turn open and my furthest open all the way and burning hot too! You have helped me no end ! Thank you
Dereton comes to the rescue as always, after a extension the new radiator was struggling to keep warm followed this advice and it has worked great. Thanks for your video. I always watch your videos. Keep up the good work.
Thanks for posting this. I had bled my radiators until it was just water. All radiators downstairs were cold. Looks like my system was unbalanced. I followed your advice and hey presto! Heat.
Thank you, after 2 radiators in our house went cold after some thermostats were fitted in our lounge we couldn't work out what had happened. It must have become unbalanced as you explained as we've just turned all the other rads off and these 2 are now working. Thanks for the tip!
Thank you very much for this excellent tutorial. I trust it applies if more than 1 radiator are not heating up (cold) properly in the same room. I applied your suggestion leaving open only the cold radiators on the same floor. It appears to be working. Thank you once again. Nicola
Had this issue today. All radiators fine with the exception of one in the kitchen. Bled the radiator slightly and then followed this video. The radiator is now steaming hot. Thanks!
Thank you for freely giving away knowledge that has probably taken you years to acquire, I have now subscribed to your channel, I hope you yourself get some benefit from these video's........ Thanks again Ray H.
Thanks for this video. Looked at many utube videos on this issue and none fixed it. Tried bleeding, knew it wasn’t that, checking the thermostat valve and balancing it no joy. Your method of turning all rads off, half a turn back on each when the problem rad warmed up worked. Yes it’s only balancing but you explained it so clearly. I’d buy you a beer if you were in the pub. Cheers🍺🍺
Thanks for you're help, even the man from British Gas didn't solve why the radiators came on except the one in our living room, which is the most important, once again thanks & thanks to RUclips.
Great video again. What can help the flow of clean water sround ghe sydtem is adding the inhibitir thats in one of your videos ALSO having a filter fitted. Sometimes you got to get a new boiler as the pump has gone, with other things likely to go and its 10 years old etc.
Nice one , old council upstairs flat with 4 runs up into the loft and down ,when I took off a radiator for decorating it wouldn't get warm again ,did as you said and balancing the system worked.
Wonderful. Worked a treat. Another video I watched (by someone else, I should add) didn't mention anything about balancing the rads, and I initially assumed my problem was therefore a dodgy TRV on the cold rad. Thanks very much.
Thanks for the video, I got a new expansion tank fitted and the system must’ve imbalanced. Been chasing the plumber for weeks to come back and sort the radiator but done it myself with your help, thanks again!
Thanks a lot it solved my issue. As you suggest I closed all radiators above and these down started working. Now will check the pump, if can increase the speed. I think - will be better if the pump work at higher speed.
Thank you so much it has worked brilliantly, we have spent many an hour trying to figure out why the radiator wasn’t working properly and your advice has saved many a headache.
My living room radiator was ice cold, it was freaky when you said it would be the living room..!! Did as you said & you sir, are a legend! Everyone who watches these kinds of videos is extremely grateful, thanks a lot buddy, working perfect now 👍🏽
Worked perfectly, thank you! I now have a better understanding of how is distributed in the home. A question please . . is it a good idea to turn off the rads in rooms which are not occupied for long periods of time?
AWESOMEEE !! thank you , what happened me was i lowered some pipes in roof space with pushfit fittings all worked except 2 radiators which would`nt bleed, could`nt figure it out, this made sense to add pressure to the remaining 2 and fixed it in seconds BRILL !!! you are the man :)
Will try this out tomorrow, the strange thing is we had a new radiator put in and it wasn't until a few weeks passed that the one closer to the boiler went cold.
Thank you for giving free advice, I'm hoping you can give just a bit more... I've just moved into my new house and have found all but one radiator gets heat all over, every single other one (9 in total) have cold spots in the centre and bottom. The radiator that is working properly looks brand new compared to the rest and I had to bleed it fully so I suspect it was replaced by the previous owner before moving. Should I turn all rads off in the house and turn them on in turn? or can you suggest anything else.
Your are right... 9/10 is that and it was that with mine too - so good to know there are people out there who know what they are talking about - Well Done and Thank You!
Thank you so much, you are a genius!!! Had to replace my 3 way valve, emptied, replaced, inhibited and the exact problem you mentioned happened once I refilled and reheated.. To make sure I had a good flow of pressure and water (when emptying) I initially opened both lock sheer and thermostatic valves. Your help by fully closing them upstairs and then slightly opening them, fixed the problem, and as a bonus I found the last RAD!!! which means I can drain from that in the future....THANKS AGAIN!!!
Thanks for this - our bathroom radiator was stone cold and we were on the verge of calling a plumber. Watched this and solved it in a couple of minutes... turned out to be the balancing thing. Invaluable!
After trying to bleed my downstairs radiators that always stayed half hot and half cold. Found this video via google and now my downstairs radiators are blistering hot. Genius!!!!
Good advice. Recently I had some plumbing done and the plumber moved the thermostat from my hallway into my living room. He also took the thermostatic radiator valves off the living room radiator. He also put a thermostatic radiator valve ob the hallway radiator which previously didn't have one. (he said this was the new/better way to do things). Now my living room gets really warm but the upstairs doesn't get warm enough. What should I do?
Hate to say this, but your system was right before being tampered with. Only thing you can do now is to turn the living room radiator right down on the wheel valve, but ultimately it would be best to have a thermostatic radiator valve on this radiator as wall.
Your videos are excellent - have recently drained the system to replace a valve on a radiator on refilling system none of the radiators are getting hot the boiler start and the pipes get hot up to the airing cupboard though the pump and bypass valve you can hear hammering have tried bleeding and have tried isolating all the Rads except 1 to try and push the air out no luck any ideas would be appreciated
+My Gezza You may need to crack a nut on the bypass or pump to let the air out. Other than that, run the heating and attach a hose to the drain valve and draw off for 30 second intervals this sometimes fetches the air down and out. It`s a case of keep trying different things.
thank you for sharing your knowledge , exactly what you said about the last radiator in the house that wasnt hot, not being balanced....that saved me a call out charge. Thankx!!!!!
Brilliant video thanks. My problem is that I can't turn the lock shield. Radiator is quite new but the lock shield has a nut around it, and will not budge (almost as though the plumber deliberately sealed it?) The radiator is a double panelled one...gets hot at back , freezing at front.
Sounds like air stuck in the front panel, there should be a septate air bleed screw for the front panel. Just put a small spanner on the hex head showing on the valve to turn it, do not worry about the big hex nut as that is the packing gland.
Thank you very much!!! It worked!!! Now tho, I hear a glu glu glu of the water running in 2 radiators....was there maybe an air bubble that now moved somewhere else in the system?
Thank you , I watched a few videos on this problem no fix then I saw your video which was the only one that was the right method and worked now my two radiators are working 😃
Had a plumber at my house scratching his head for 4 hour why these new rads wouldn't heat up. Blamed it on the valves! Thank you for your video sorted it out in under a hour.
Thanks for your help I have balance them my plumber put a new pump on yesterday but still no heat would the pipe work be to small to run the water all the way I'll get back to you if I salve the problem to tell what I did tomorrow
Hi Edwin , it will not be any thing to do with the pipework it will either be air in the system or you have added to many radiators for your boiler to cope with. How many rads are there on your boiler? is it a combi? What make and BTU output is your boiler? Get back and let me know Regards, al.
Great instructions. My system is a F&E tank in loft, which i believe is a vented system. The other day took some water (about 2 large milk bottles worth) out of the system at the radiator drain points downstairs, and at the boiler return point drain valve. With system cold, Have bled air from the radiators downstairs without any problems. However, the 4 radiators upstairs, no water is coming out of any of them when the radiator bleed screw is opened. Any thoughts. Thanks
Thanks a lot this really helped me out. Had one radiator that wouldnt heat up at all, tried other ways of balancing the rads and had no luck, even had a plumber try balance them but didnt make any difference! Turning all the other rads off first worked really well! Love the channel keep up the good work 👍👍👍
Awesome simple video, worked a treat on my en suite radiator - thanks so much 👍 @dereton33 I have another problem with the radiator in my kitchen though. It's closest to the boiler but doesn't come on at all. Neither pipe going into it have any heat either. Is it worth me replacing the trv or is that not the issue as the pipes themselves aren't hot? Thanks in advance for any help
Better than that, take the top off of the TRV and I think you will find the pin stuck down, either pull it up with pliers, or give it a tap with a small hammer until it pops up.
hi Dereton, thanks. very good tips as always, shutting the all off didn't work unfortunatley just changed two old donwstairs rads on drained gravity fed system, the one new rad and all the others are fine. bled, rads, system and pump. the one new rad is stone cold. feed and out and cold. i am trying to avoid connecting a hose and trying to force the airlock out into the tank. any ideas? thanks.
If it is a downstairs one on a dropped pipes from the ceiling then stick a hose non the drain valve turn on the heating until other rads get hot then open the drain valve and run some water off outside until the pipes get hot then shut off the drain valve.
I have tried everything thing you suggested and all I am getting is hottish water to the inlet of my down stairs rad. It’s cold to Luke warm on the return side. I have replaced the radiator , lock shield and trv. Bled the system countless times. Flushed system through. Put cleaner in. The Boiler is in the loft an ideal isar HE24. The radiators upstairs can get very hot if I turned them up. Tried turning all other rads off to force hot water down to rad that’s not getting hot. I am stuck with what to do next. I replaced the pump roughly 3 or 4years ago as it was leaking. Could the pump be faulty not having enough capacity to pump down stairs. Rad has never been great down stairs even after putting a new one in. Only running 4 rads up stairs a under unit fan heater down stairs and a double rad. So not exactly over the top.
It could be the pump, but it might also be something as simple as the thermostic rad valve not working properly. As you have tried all the usual suggestions, it has to be a blocked rad valve or the rad itself may need taking out side and flushing through.
Hello Just a quick question Iv'e got an extension with 5 new rads 2 up 3 downstairs the 3 rads downstairs won't heat if I turn all the rads off they heat but very slowly and then when I put the others on they cold down again Tried the things you said on your video many thanks
Hi Edwin , I think you will need to balance them , I have a video on my channel for that , if that does not work then you may need a new pump , ( you can try turning the speed up to 3 ) failing that if these rads in the extension have been added to the rads you have already in your house , then your boiler may well be under powered. Kind regards, al.
Hi i like your video very much i have got old back boiler in my living room and my tanks upstairs are dirty i would like to clean it fully in summer i cleaned each rad already with garden hose when i was decorating but was taking few off several times and mess was always there just wondered if i clean such a old system would it not do more harm than good if any cleaner added. Regards.
Hi Justyna , I have heard of some old radiators leaking when inhibitor has been added as it removes the sludge ect that may be preventing a rad from leaking . I would still take the chance and add the inhibitor as a clean system runs so much better and warmer , but it is up to you. Kind regards, al.
Hi Juatyna , put the full bottle of inhibitor in your small F and E tank and not your large cold storage tank in the loft . If you want to add cleaner for a week , then drain it out and put in inhibitor , that would be a better bet . Regards, al.
Your advice was spot on! We'd had new, larger and extra radiators installed recently during a refurbishment. I turned all the radiators off, then on 1/4 of a turn at the valve (rather than the temperature valve) and opened the cold radiator to full.

As the other reviewers have said this is a highly recommended video for sorting out a problem radiator. Your video on balancing is also very useful.
Thanks David.
Thank you so much for this! I had given up on this and had 2 very cold rooms literally for years! i feel like a right eejit! Wish I could buy you beer!

Fred V No problem. Al.
This is why I love RUclips! Amazing. This fixed my central heating problems.
It`s not U-tube, it is us guys prepared to give our time and knowledge to help out.
Had the council out who did this technique to get my last rad on the system (downstairs bathroom no heat at all despite bleeding). Which worked. He showed me what to do etc incase it happened again.
The next day though, same again, back to no heat !!!

No problem, pleased you now have some heat. Al.
Thank you so much! I have been struggling getting heat into our lounge for literally months.
Twenty minutes and you have solved us a massive problem.
All our lockshields were wide open.
Now sorted and ALL radiators are hotter than they were.
Again, thank you so much.

Thanks for your help. I called a plumber, but he failed to show. After listening to your advise about balancing radiators, I set to work. System works well now, thank you
Joe wigfall Great!! Saved you some money!! Al
This guy is blinking good, Love your videos.... very helpful..... You are the ORACLE!!

Thank you for this - the third way solved our problem!
Very clear information. The balancing steps brought my dead hallway radiator back to life. Thank you for your video..

Sometimes you got to get a new boiler as the pump has gone, with other things likely to go and its 10 years old etc.
Brilliant, thank you so much. The rad that was moved was just barely warm - you're a star. The balancing trick did it.
No problem.
Thank you, thank you, Thank you...you solved my conundrum that the local plumber couldn't. 17 rads and the end one just wouldn't get hot. Done.
Great.
Nice one , old council upstairs flat with 4 runs up into the loft and down ,when I took off a radiator for decorating it wouldn't get warm again ,did as you said and balancing the system worked.

Everyone who watches these kinds of videos is extremely grateful, thanks a lot buddy, working perfect now 👍🏽
No problem.
Thankyou. I’m going to try to balance them tomorrow. I’ve got 1 downstairs getting lukewarm and one that’s stone cold. All other rads are hot.
Good luck!
Thank you sir 🙏 got my radiators working again, and they are perfectly balanced now 👌
No problem.
Thank you a lot. This fixed the weird rad downstairs after 8 months of head-scratching. Great advice and vid!
Oh and donating now.
Thanks a lot Cian.
Balancing the rads worked a treat. Thank you v much.
You're welcome!
Worked perfectly, thank you! I now have a better understanding of how is distributed in the home. A question please . . is it a good idea to turn off the rads in rooms which are not occupied for long periods of time?
Yes.

Will try this out tomorrow, the strange thing is we had a new radiator put in and it wasn't until a few weeks passed that the one closer to the boiler went cold.
Thank you for giving free advice, I'm hoping you can give just a bit more... I've just moved into my new house and have found all but one radiator gets heat all over, every single other one (9 in total) have cold spots in the centre and bottom. The radiator that is working properly looks brand new compared to the rest and I had to bleed it fully so I suspect it was replaced by the previous owner before moving. Should I turn all rads off in the house and turn them on in turn? or can you suggest anything else.
Hi Mark, the radiators are blocked with sludge, drain down the system and add cleaner followed by inhibitor, that usually does the trick.
+dereton33 Thank you very much, I'll do just that.
Thanks. I Will try this. I have three rads in the loft two are working but one is not.
Your are right... 9/10 is that and it was that with mine too - so good to know there are people out there who know what they are talking about - Well Done and Thank You!
Right on!
Thank you so much, you are a genius!!! Had to replace my 3 way valve, emptied, replaced, inhibited and the exact problem you mentioned happened once I refilled and reheated.. To make sure I had a good flow of pressure and water (when emptying) I initially opened both lock sheer and thermostatic valves. Your help by fully closing them upstairs and then slightly opening them, fixed the problem, and as a bonus I found the last RAD!!! which means I can drain from that in the future....THANKS AGAIN!!!
No problem Darren.
just when i thought id have to pay out some more money, i owe a thanks to this guy! Much appreciated
No problem.
Thanks for this - our bathroom radiator was stone cold and we were on the verge of calling a plumber. Watched this and solved it in a couple of minutes... turned out to be the balancing thing. Invaluable!
Jon Gritton No problem Jon . Al.
After trying to bleed my downstairs radiators that always stayed half hot and half cold. Found this video via google and now my downstairs radiators are blistering hot. Genius!!!!
No problem.
Thanks for your video. Its so easy when you know how. You saved me a few bob.
Thanks mate... The air lock technique worked perfectly.
No problem 👍
you just saved me call-out charge as i only have boiler cover.
thank you very much.
keep up the good work.
No problem.
Good advice. Recently I had some plumbing done and the plumber moved the thermostat from my hallway into my living room. He also took the thermostatic radiator valves off the living room radiator. He also put a thermostatic radiator valve ob the hallway radiator which previously didn't have one. (he said this was the new/better way to do things). Now my living room gets really warm but the upstairs doesn't get warm enough. What should I do?
Hate to say this, but your system was right before being tampered with. Only thing you can do now is to turn the living room radiator right down on the wheel valve, but ultimately it would be best to have a thermostatic radiator valve on this radiator as wall.
Great tip. Just saved me a whole lot of bother after getting a new boiler fitted. Thanks.
No problem.
Your videos are excellent - have recently drained the system to replace a valve on a radiator on refilling system none of the radiators are getting hot the boiler start and the pipes get hot up to the airing cupboard though the pump and bypass valve you can hear hammering have tried bleeding and have tried isolating all the Rads except 1 to try and push the air out no luck any ideas would be appreciated
+My Gezza You may need to crack a nut on the bypass or pump to let the air out. Other than that, run the heating and attach a hose to the drain valve and draw off for 30 second intervals this sometimes fetches the air down and out. It`s a case of keep trying different things.
thank you for sharing your knowledge , exactly what you said about the last radiator in the house that wasnt hot, not being balanced....that saved me a call out charge. Thankx!!!!!
No problem.
Brilliant video thanks. My problem is that I can't turn the lock shield. Radiator is quite new but the lock shield has a nut around it, and will not budge (almost as though the plumber deliberately sealed it?) The radiator is a double panelled one...gets hot at back , freezing at front.
Sounds like air stuck in the front panel, there should be a septate air bleed screw for the front panel. Just put a small spanner on the hex head showing on the valve to turn it, do not worry about the big hex nut as that is the packing gland.
Thanks, your solution cured our bathroom towel rail that was not heating up.
No problem.
Mate,
thank you very much for sharing this, you have just saved me a few bob calling out a plumber that I can bot afford.
I owe you a pint mate.
That`s ok Simon.
thanks chap . new pump is firing them all up nicely
Just used this video to help me with my issue and worked. Fantastic! Thanks
No problem
Thank you. It worked!!! My system was unbalanced. Excellent advice. Thanks again.
No problem.
Thanks for that. I have tried everything and was about to bin the radiator. Cheers
No problem 👍
Legend! It worked. As soon as I turned the rest off it was hot within 1 minute. Thank you.
No problem
Thank you very much!!! It worked!!!
Now tho, I hear a glu glu glu of the water running in 2 radiators....was there maybe an air bubble that now moved somewhere else in the system?
Try bleeding the radiators.
@@dereton33 had to let a lot of water and eventually some air, but it worked! thanks!
Thank you , I watched a few videos on this problem no fix then I saw your video which was the only one that was the right method and worked now my two radiators are working 😃
That`s great Julie.
your a legend mate! tried everything else then came across your video, it worked straight away! thanks champ i owe you a beer!
No problem. PS it`s John Smiths.
Had a plumber at my house scratching his head for 4 hour why these new rads wouldn't heat up. Blamed it on the valves! Thank you for your video sorted it out in under a hour.
Fantastic!
Thank you SO much, just turning them all off and then back on afterwards did the trick !! So happy and grateful
No problem.
What a Guy....Awesome Geezer !!! You are a star !!!
Thanks for your help I have balance them my plumber put a new pump on yesterday but still no heat
would the pipe work be to small to run the water all the way
I'll get back to you if I salve the problem to tell what I did tomorrow
Hi Edwin , it will not be any thing to do with the pipework it will either be air in the system or you have added to many radiators for your boiler to cope with. How many rads are there on your boiler? is it a combi? What make and BTU output is your boiler?
Get back and let me know
Regards,
al.
Great instructions.
My system is a F&E tank in loft, which i believe is a vented system. The other day took some water (about 2 large milk bottles worth) out of the system at the radiator drain points downstairs, and at the boiler return point drain valve. With system cold, Have bled air from the radiators downstairs without any problems. However, the 4 radiators upstairs, no water is coming out of any of them when the radiator bleed screw is opened.
Any thoughts. Thanks
Roof tank valve in the F and E tank is jammed off. Go up and give it a wiggle.
Amazing, you were spot on. The ball in the F&E tank was defying gravity, and the tank was empty. A little wiggle sorted that out. Thanks
No problem.
Thanks a lot this really helped me out. Had one radiator that wouldnt heat up at all, tried other ways of balancing the rads and had no luck, even had a plumber try balance them but didnt make any difference! Turning all the other rads off first worked really well! Love the channel keep up the good work 👍👍👍
Thank you.
You're a star! Amazing. Thank you for the advice.
No problem.
Awesome simple video, worked a treat on my en suite radiator - thanks so much 👍 @dereton33
I have another problem with the radiator in my kitchen though. It's closest to the boiler but doesn't come on at all. Neither pipe going into it have any heat either. Is it worth me replacing the trv or is that not the issue as the pipes themselves aren't hot?
Thanks in advance for any help
Better than that, take the top off of the TRV and I think you will find the pin stuck down, either pull it up with pliers, or give it a tap with a small hammer until it pops up.
Thank you - this worked for me, excellent clear and well explained advice.
hi Dereton, thanks. very good tips as always, shutting the all off didn't work unfortunatley just changed two old donwstairs rads on drained gravity fed system, the one new rad and all the others are fine. bled, rads, system and pump. the one new rad is stone cold. feed and out and cold. i am trying to avoid connecting a hose and trying to force the airlock out into the tank. any ideas? thanks.
If it is a downstairs one on a dropped pipes from the ceiling then stick a hose non the drain valve turn on the heating until other rads get hot then open the drain valve and run some water off outside until the pipes get hot then shut off the drain valve.
I have tried everything thing you suggested and all I am getting is hottish water to the inlet of my down stairs rad. It’s cold to Luke warm on the return side. I have replaced the radiator , lock shield and trv. Bled the system countless times. Flushed system through. Put cleaner in. The Boiler is in the loft an ideal isar HE24. The radiators upstairs can get very hot if I turned them up. Tried turning all other rads off to force hot water down to rad that’s not getting hot. I am stuck with what to do next. I replaced the pump roughly 3 or 4years ago as it was leaking. Could the pump be faulty not having enough capacity to pump down stairs. Rad has never been great down stairs even after putting a new one in. Only running 4 rads up stairs a under unit fan heater down stairs and a double rad. So not exactly over the top.
It could be the pump, but it might also be something as simple as the thermostic rad valve not working properly. As you have tried all the usual suggestions, it has to be a blocked rad valve or the rad itself may need taking out side and flushing through.
That did the trick, Big Al!
Thanks for warming up a little piece of New York City.
No problem Hugh , must be one of my favourite city`s iwas there myself for a week last May.
I'm glad you enjoyed your holiday here.
Come back and your first pint is on me! :)
Hello Just a quick question Iv'e got an extension with 5 new rads 2 up 3 downstairs the 3 rads downstairs won't heat
if I turn all the rads off they heat but very slowly and then when I put the others on they cold down again
Tried the things you said on your video
many thanks
Hi Edwin , I think you will need to balance them , I have a video on my channel for that , if that does not work then you may need a new pump , ( you can try turning the speed up to 3 ) failing that if these rads in the extension have been added to the rads you have already in your house , then your boiler may well be under powered.
Kind regards,
al.
Hi i like your video very much i have got old back boiler in my living room and my tanks upstairs are dirty i would like to clean it fully in summer i cleaned each rad already with garden hose when i was decorating but was taking few off several times and mess was always there just wondered if i clean such a old system would it not do more harm than good if any cleaner added.
Regards.
Hi Justyna , I have heard of some old radiators leaking when inhibitor has been added as it removes the sludge ect that may be preventing a rad from leaking . I would still take the chance and add the inhibitor as a clean system runs so much better and warmer , but it is up to you.
Kind regards,
al.
Hi Juatyna , put the full bottle of inhibitor in your small F and E tank and not your large cold storage tank in the loft .
If you want to add cleaner for a week , then drain it out and put in inhibitor , that would be a better bet .
Regards,
al.
Excellent advice. Worked like a dream, after British Gas engineers had no solution to the problem. Thanks!
***** No problem Robin. Al.
Always a great help your videos, helped me a few times with various issues regarding heating systems. Cheers 🍻
No problem 👍
