Hi all,
I have a rad that has suddenly started making a loud knocking noise when the heating comes on, usually last about 5mins. It's a relatively new rad, installed 4 years ago. I've tried adjusting the flow and return but this hasn't stopped the knocking.
Any idea what might be causing this and tips to sort it?
