Radiator rattling even if closed off

[sulking1]

Hello,

i've got this horrible radiator that keeps rattling like a tapping noise when the heating is on, it will rattle every 20mins and even if i turn the valve off together with the lock shield it will still rattle ??

obviously it won't rattle when the heating is off

anyone help i'm going to try a flush or just replace the radiator but any suggestions its just one radiator in the main bedroom all others are fine.

thanks.

Hello

Could be expansion/ contraction creep, are the plastic inserts fitted where it hooks on to the radiator bracket?

Yes the inserts are all there, if i push onto the rad it still does it.

check and secure (with hair felt between pipe and any timber) the pipework leading to the rad and others near by.

it could also be another valve on the system causing small vibrations and that rad and pipework to it is just being effected most by it.

if it has a trv it could be one that flows one way only and is on the wrong way round, that makes em rattle like hell

Either pipe expansion when heating is on or single way thermostatic valve. try removing trv head if fitted.
