I have lived in this one family house for 10 years, with 3 separate hot water baseboard heat zones, in winter I have always heard pinging/ticking from pipes as they expand and contract. This winter is the first time I am hearing this new bang/noise/shudder/tremble from water heating pipes. These 1-2 loud bangs are followed by a tremble that reverberates throughout the house perimeter. I can hear these bangs about a second before I hear the sound of what sounds like a valve being closed, and then all goes quiet again until heat is called for again. It seems like at least 2 zones are experiencing these bangs, one zone being much louder than the other. I have drained all zones to be air free. What else should I look at? Thanks for the help. Vlad.
