We have a Grandee combi oil boiler which appears to be working ok but over the last week it has started making a "knocking" noise about an hour after it has been on.
It then continues to knock on a regular basis until it goes off
We have been in the house for 2 years and this is the first time it has done this. It was serviced about a month ago and everything was fine then
Any ideas anyone?
