Radiator Groaning

[scrivomcdivo]

Recently, the radiator in our main bedroom has stated making really, really loud groaning noises. The noises last about 30 seconds and they resemble the sound of a drill going through some masonry brick. It only happens on the one radiator; this being in the room in which the boiler / airing cupboard is in.

Any ideas / suggestions? Does it just need bleeding?

does it have a trv

Yes it does. This is where the sound seems to be coming from.

suprise suprise its either on the wrong end
or you don't have a big enough bypass
or it's gone to meet it's maker

change the valve is the short answer

Cheers for that.

It's only recently that it's started making the noises. With that, does it mean that it needs replacing as it's never been noisy previously. Also, I recently turned the valve to "max" - would this have had an effect?
