Edward try lowering your thermostat
then see if the noise stops.
Sometimes on hydronic systems we have a condition called “hunting” where a zone valve HUNTS (chatters) as it isnt quite satified as to the proper setting.
Hey its worth a shot.
I had this happen a lot as a stationary engineer on a high rise building especially with older valves.
