To bleed a radiator look at the top of the side of it. It'll have 2 nut type things that are a couple of inches in diameter, 1 will be flat, 1 will have another small nut in the centre of it. Go to the 1 with the nut in & use either a radiator key or screwdriver (if it has the slot as modern 1s do) to slowly turn it until air hisses out. Have an old cloth/bowl to hand to catch the water that spills out & then give it a while to heat up.

Depending on what type of boiler you have, you might need to top up the pressure again afterwards (if you have a combination boiler you'll need to) which is really simple on most boilers. It's usually a case of turning 1 or a couple of little tap handles until it reaches the right level on the gauge.

If bleeding doesn't work turn all the other radiators off & leave the dodgy 1 on on it's own for about half an hour. That sometimes forces things around & sorts it out.



Sounds like the sludge in your system could be building up meaning you could need a flush of some kind. Depending on the age of your system, the best thing is a Power Flush (also known as a Jet Flush) which involves hooking up a machine to your system & blasting a chemical around it to remove some of the [Poor language removed]. They're expensive due to the amount of time they take (depends on how bad the build-up is but they take at least a few hours) & the price of the machines & no places that I know of guarantee they'll work but the vast, vast majority sort the problem out.

I have a habit of forgetting about threads after I've posted in them so if you need any more help & I don't respond PM me a reminder

2 years old, combi boiler, brand new radiators with valves at the bottom :-/

Not a blockage then so forget about a flush.

Might just be a lot of air but normally air causes the radiator to be cold at the top & warm at the bottom. Ignore the valves for a minute, look on the side panels about an inch from the top of the radiator, there will be a nut on either side, 1 will be flat, the other will have another smaller nut. Bleed it like I've said above & then you'll need to top the pressure back up which should be simple enough, depending on what boiler you have

Just remember one thing. Don't forget to turn off your central heating and let it get cold before you bleed. I forgot that little fact and managed to flood out a few of our rooms in the house.

Other than that its dead easy. And when mine was cold from the bottom up, I bled it anyone, and it worked. Dont ask me why, not my area of expertise, but just do it.

How did you manage that?
