Humming Radiator

[tatters40]

Hi Guys

Hope you can help

My living room rad gently vibrates when the boiler and pump are in operation. When they 1st fire up there is a quite noisy humming from the same area which slowly quietens down but remains in the background until the boiler switches off. This continues every time the boiler kicks in. it's becoming a little annoying now, any ideas?

Many thanks

consider putting some cable wire or silicon insulation on the mounts to make "rubber" feet.
Bleed it, it could be bubbles
check your TRV is not directional and on the wrong side

remove the sensor head from the TRV and see if the noise stops no tools needed it will just screw off)
