bleedin radiator!!

[beatts]

Hi,

we had a radiator recently fitted and everything was great. However we have to bleed it every two weeks or so. Every other rad in the house is fine, just the new one.

any ideas??

Is the radiator the same temperature at the bottom and along the top ?

it is hot on the bottom, cold on the top

Then you still got air in the radaitor,keep bleeding it until the top get hot but take great care.Might take a couple of days to get rid of it all.

we do keep bleeding it, and all is ok for about two weeks then it needs bleeding again. Do you think maybe its gradual over the two weeks and its only when we notice it we decide on bleeding it.

It might be hydrogen and not air then. Hold a container upside down over the bleed valve and collect some gas. Keep it upside down and see if you can light it. If its hydrogen, you need to flushout whatever is causing the problem, or tell whoever fitted it.
