Hi, if it sounds like bubbles thats ok, but it needs to be bed from the radiator valves to quiet that down.

Does the boiler run ok sound wise?

Thank you

The noise STOPS as soon as the heating is switched off.

Hi if it all seems to be running normal, heat and all Its probably a vibration. No big deal. But if it hasn't been professionally cleaned in over a yer , it needs to be because that too can cause this issue, due to soot and dust build up.

Any local heating company can do this for you for a fair price;-)

In any case, I will stick with you until this is complete.
