Hi all
am currently hearing a loudish vibration sound (rather than rattling) in the CH system, particularly upstairs. Its deffo not the pump, and the rads are fully bled. Prob an obvious one for you guys but not for me!

thanks

Try adjusting the valves on the radiators when the noise occuring and see if the noise stops.
