One Radiator not heating

[HantsHelp]

Hi!,

One of my downstairs rads is not heating. The pipe running into it heats but none of the rad itself. I've bled the rad and seems to have good pressure with no air coming out.

I have a gas boiler upstairs with tank in the loft.

Any suggestions for me?!

Thanks very much.

balance the system.

bleed and see if the water is black with sediment.

look in the bottom of the F&E tank and see if it has a layer of sludge.

if the rad has a TRV see if it is jammed

Tell us if it is microbore

Tell us how long it has been like this

tell us what has happened since it last worked
