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 RU-vid. Society are gaining the equivalent of a RU-vid 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.
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.
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!
Half the people watching actually want to know how to do this The other half are plumbers (like myself) checking you gave all the right information lol, I was glad you even mentioned that the nut can come loose (I hate that) One thing you could've said as well is if you have a low pressure heating system, don't take the pin right out to try and bleed it quicker...I did this many years ago as an apprentice and struggled to get the pin back in with all this black water shooting everywhere lol. Good video well informed Don't worry, all those dislikes are from cowboys who would callout charge just to do this for a customer
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...
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
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.
You Tube....one of THE great inventions! You get guys like this sharing their knowledge for nothing, just to help others out...Allen, thanks for your efforts and long may folk such as yourself continue to help us all wade through the intricacies of plumbing!
@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
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!
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.
No hate at all here but worth mentioning the lockshield bit again to people doing this for the first time, he mentions the balancing briefly. The downstairs ones can be fully open but the upstairs ones need to be open about a quarter turn roughly as a guide to balance the system. If you have messed about with these you need to balance the system so watch his vid on how to do it 👍🏼
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 🎉
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.
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.
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.
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!
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.
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
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 🤷♂️
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!
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
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.
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.
This guys videos are priceless.👍 #justsayin A quick question for anybody that's wants to answer. My boiler has no controls on it. Possibly an old system. Gravity fed system I think with big copper tank. Is this a system which corrects the pressure itself?? I have a big water tank in the loft, a copper tank upstairs in a cupboard, and a boiler in the kitchen Cheers.
My old system was similar to yours plus a small water tank to feed to the boiler circuit. I still had to bleed the radiators but it tops up itself from the small tank.
@@ericmcrae7758 cheers mate these systems seem like rocket science to me. I literally have NO clue. A hole popped in the bottom of a radiator a few weeks ago too. Been told the system needs flushing. Do you have any idea on a fair price for flushing a system?? Some of these plumbers are dodgey. Not our Allen tho! Haha.
@@DICKTURPIN1976 the rad needs removing and throwing away. You'll prob need new rad valves too (because the old ones will leak) and more inhibitor. You might want to consider a new system if its all quite old? If one rad has gone, the others might be on the way out as well.
The bit where you show the TRV pin sticking down is a lifesaver mate, but can I suggest making that bit a separate video, or calling this video something like "What to do when radiator is not working" or something. I had the stuck down pin issue, and I bled and bled my radiator. I was sure there was some kind of airlock. I just saw that bonus bit of advice by chance.
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.
Thanks for the video really helped me out sorted my central heating ready for winter! This is a must with the current energy crisis my girlfriend reminded me we still get charged even if they don’t work. Never completed a task quicker 😂
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?
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 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
Got a Danesmoor 15/19 and had all new rads throughout the house with fresh water with anti corrosion additive. Bleeding was easy and all of them like toast after about 3/4 hr. Good reliable little boiler.
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?
I like that radiator key with the wide grip for turning the valve. I have a key with a narrow crossbar that is hard to turn without gripping it with a wrench.
