How to Fix Cold Radiator. Most Common Reason for Radiator Not Getting Hot. Thermostatic Valve Stuck

[@flabbybellyproductions7969]

Thanks. This gives me confidence in fixing myself. Old radiators in our new house every now and again stop getting hot. Now I know what to do

[@davebarlow6457]

Thank you. I followed your instructions and managed to get my cold radiator working again and probably saved myself no small amount of money. This was much appreciated.

[@kellyphoover]

This totally worked! And took two minutes, thanks Mark and KZbin!

[@rj12341]

Absolute lifesaver, i tried bleeding my radiator and bled it so much i had low pressure on my boiler so had to youtube how to sort that, was thinking about messaging a plumber but found this video and it worked a treat! thank you so much!

[@bogdiworksV2]

thanks, all the banging on the pin helped ;-) you're hands down one of the best plumbing teachers out there.

[@adilomar2560]

Thank you, I just moved in to the house and one of the radiator wasn't getting hot. My problem was I need to remove the the white cup or the thermostatic. And it works, Thanks again.

[@kh2945]

Well explained. Also like the fact you showing different radiators!

[@ollyf5088]

This isn’t the first video I watched on thermostatic valve pins but it’s the only one that explained how far the pin should be exposed when heating is on. Cheers mate you’ve solved my problem and saved me phoning British Gas 👍 have a great Christmas!

You are my North Star.

[@margaretcoley1143]

Thank you for this explanation.I am going to try this before I have to get in an engineer in .Will update if it eorks.Thanks again.

[@irnbruo3]

Thank you so much for this fixed cold radiator in 2 mins flat ....heat glorious heat at last 🥳

[@UxbridgeDalek]

Thanks for this Vid Mark. My sons radiator wasn't eating up at all. 3 or 4 taps on the valve pin and it's fixed. It's taken me longer to type this comment that the fix :D . Now I just need you to do a vid on balancing the radiators throughout the house.

[@zangimusic]

Legend!!!! Thank you, your tips are amazingly helpful

[@m.ismailalaoui9873]

You are the Best one ever seen

[@bobbojones8157]

Ice demonstration mark I’m just going out to do just that for my mates daughter . Hoping I’ve not got to drain down and replace the valve . I personally haven’t got thermo valves they are more trouble than they are worth . - very old retired plumber😊

[@rajeshmanikumarg5436]

Worked as guided. It solved the issue. Very helpful. Thanks. Good Day!

[@vipulasamudre]

Your video ms r really helpful

[@halemcdan1]

Thank you. I had exactly this problem. Mine took a few taps to shift.

[@nicholacochrane326]

Superstar!! Thank you

[@badrulchowdhury1362]

Thanks for well explanation

[@markferg1957]

very useful video. How do you address this problem for bathroom radiators which has a valve controlled by a tap rather than a thermostatic valve?

[@nosracoon]

Cheers from an Australian living in Europe who's never had to deal with central heating before.

[@cyril4892]

also dont forget to turn on "heating mode" on your boiler ;)

[@cdh601]

Put the hammer down for a minute and try shutting the lockshield valve and release the pressure in the radiator though the bled valve ..now you have the system pressure pushing on that stuck TRV

[@neil5006]

Thanks Mark 👍

[@dazecm]

Great tips. One upstairs radiator in my house is cold, the rest are fine. When I check the inflow pipe of the cold radiator bellow the thermostat valve it's always cold, not even warm. What does this signify?

[@AlexN0me11]

Should you expect the pin to get stuck after just one year? I’m having issues with radiators being luke warm. I had a new Worcester Bosch boiler and new radiators installed about a year ago.

[@michaelrutherford3926]

Tried valve pin, bled radiator, flushed radiator. Radiator still cold. Pipe running to lockshield valve also cold. Any thoughts?

[@petermorris5142]

Can I use wd40 it actually worked brilliant

[@westwonic]

I have a bathroom towel radiator that no longer provides any heat at all. I have replaced both the trv and lockshield valves after draining the open vented system. Still no heat. I thought perhaps an airlock, so I connected a garden hose to the top mounted bleed valve, and tried to flush through via the flow and return alternately. I was surprised the mains water didn't come out of the external lowest drain clock. Any ideas?

[@MarkBallardLTD]

Sounds like a blockage.

[@westwonic]

@@MarkBallardLTD Yes, just found that both flow and return pipes are blocked in flexi pipe bends below the floor. I thought these were only for hot and cold services, not heating....

[@Ritah57]

Hi the pipe on one side of the radiator is really hot and the other side is not at all but I can't seem to find a pin on my valve mine looks quite different anything you can recommend?

[@MarkBallardLTD]

Without seeing it I can not tell. But if one of the pipes is really hot that is almost certainly going to be the flow pipe. And the radiator should get hot if both valve are open. so do check both valve.

[@backstickproductions]

My radiator doesn’t have a pin as such when I remove the thermostatic valve. It’s more of a thicker rounded end. Any suggestions please Mark?

[@MarkBallardLTD]

If it's a thermostatic valve you have. I know the sort you mean. rather than a pin, there's a larger button in the middle. Still works exactly the same tap it gently and hopefully it will release.

[@backstickproductions]

@@MarkBallardLTD thanks for getting back to me. I actually managed to fix it in the end. It turned out it was something much more simple. The value on the other side just needed turning! Think when we got a new combi boiler fitted a few years back they played around with it and didn’t put it back. Thanks again!

[@slvs91]

My radiators first get hot at the top and then takes ages to heat at the bottom,is that normal? Radiators are 2 years old 1x 1800x600 1x1600x600 1x 1400x600 1x1200x600 all type22 plus one tower rail .

[@paul_my_plumbs_uk]

HAMMER TIME!!!🔨🔨🔨🔧🔧🔧

[@jezjones4719]

Recently repainted my bathroom radiator and since then every time I have the radiator on our bathroom towel sticks - fluff now stuck all over the radiator! I now need to lightly re sand but worried it will reoccur again once again, Any tips please or what have I done wrong ?? Please help !

[@MarkBallardLTD]

sounds like the paint does not like getting hot. Try spraying it with clear lacquer.

[@missdhara6434]

I just changed my boiler, All raditors in the house are hot except 1. The plumber bled it until water came out a a couple of times.Hes opened teh valve all of the way too. It gets warm, then it goes cold again. No one can figure out why its happening! its a Burnham boiler we just installed (Im located in NYC)

[@HalogenStarMusic]

What would you think would cause a radiator only heating at the top edge and sides but remain cold in the middle and bottom?

[@cyril4892]

there is mud inside

[@stefanp6141]

Have your heating system power flushed

[@paul_my_plumbs_uk]

Magnetite 💩 you may need the system flushed and serviced

[@MarkBallardLTD]

Basically you have poor flow though the radiator. make sure both valves are open. Try turning off all your other radiators see if it comes to life. Other than that, trying to work out why it has poor flow. not always an easy job.

[@kjanhasan9152]

Hi Mark, can you please tell me would the BTU on old radiators (20 year old) have been the same as the ones we buy now, eg on 1600mm x 600mm double? Or did the old ones have a lower BTU then?

[@MarkBallardLTD]

If the old radiator has fins on it should be about the same size for size. If it has no fins on the back of it, then it is just a radiator which will not put out as much heat a as a radiator with fins on called a convector radiator. Hope that make sense.

[@audreywilson4361]

I have a problem with my central heating no heating at all I have changed my radiators and now I was told that there slugs in the pipe how could I get this sorted I’m really stress out I try everything I power flush the system still no heat from the radiator please I need help what to do I was told to changed all the pipe work which so expensive

[@stefanp6141]

Thank you Mark! Could you also make a video on common causes and how to fix circulation pump and motorised valves getting stuck/stop working

[@bobbob4614]

I have a problem were not all my radiator is heating up top half colder than bottom. I have bleed the radiator but no air comes out only water. I do it in order of first radiator heating up to last but not a bit of air comes out. Any idea

[@Kelvin_7]

Thank you for the good job, I was at the verge of calling an engineer to look into my radiators issues. Having watched your video done the miracle. Thank you for helping out.

[@twinflamegirl9901]

I spent£1,00+ getting engineers to fix this issue over 3 yrs… prob worse. Doing maintenance yourself is priceless

[@juliancamies3142]

Tap tap tap tap. Did the trick, thank you so much for the advice and instructions. 👍🏻👍🏻👍🏻

[@johnmitchell3719]

i have a radiator that is hot at the top and cold at the bottom is there an easy fix? i have a magnetic filter near the boiler.

[@brianjames6890]

Cheers Mark, thoroughly enjoyed your video. Many thanks👍👏👍👏👍👏

[@Clifford_Banes]

This video says you should use the pliers to pull the pin out kzbin.info/www/bejne/raLOppKImMSMq6s

[@sandrascott4685]

You are brilliant….with a really cold spell and family coming for Christmas you have been incredible..Thank you soooo much!

[@Claw74372]

Thanks. Just fixed my son's radiator in his room.

[@daveg6948]

Really helpful thank you, I wish you lived next door to me :-)

[@kuzukuzu2615]

Thank you very informative.

[@yujiadutbhoyroo9194]

Excellent. Good presentation.

[@PaulKerr_1]

Just tried this and radiator still not getting hot. Valve seems ok. Pipe on one side is warm. What else can I try?

[@MarkBallardLTD]

make sure the valve on the other end is turned on. Turn off all your other radiators see if it gets hot with heating on.

[@ichdenker]

Very useful information

[@MrDaiseymay]

PAY YER GAS BILL

[@johnf3326]

Can't help but like this guy. Very jolly but also very knowledgable

[@PrivateWalker]

Rip it all out & fit storage heaters then there's never any maintenance, breakdowns, expensive services & no new very expensive boiler needed every 9 or 10 years. Much more efficient & doesn't produce CO2 from burning fossil fuel. (£150ph greedy engineer never required to rip you off on parts & labour either!)

[@paddy9985]

Great video.

[@frankfitzsimons4442]

Did exactly as you said in the video and it worked straight away. Thanks for putting this on here and for sharing your knowledge and experience for everyone to learn from you. I'll be back!!!
