      I have a new home built in 2001 with hot water baseboard oil fired heat. I have 2 issues: 1) clanging in one room on its own zone-sounds like someone is shaking pipes, the room is right over boiler. 2) periodic popping or snapping coming from two seperate baseboards. Usually when heat cycle begins or ends. What can I do? I been told to check floor boards around copper pipe for clearence and/or remove hard filler that plumber used to fill hole in floor around pipe that feeds baseboard. Please advise. Thank you

      You are being advised well.

      An added issue may be that you have the zones. When zone valves are closed, the full flow of water is not available, so water might not be flowing through the boiler fast enough to prevent local boiling. the collapsing of steam bubbles as they hit cooler water above in the piping can create rumbling. You might need a boiler bypass installed to maintain a minimum flow rate.
