We have a three zone system. Our bedroom is at the end of a zone, so the return leaves our room and runs the entire basement back to the zone valve and boiler. At night when it's quiet it is possible to hear the gears of the zone valve close when the thermostat is satisfied. The valve is approximately 60 feet away from our bedroom and in the basement. It is not possible to hear the same zone valve when in my daughters room which is immediately above the boiler. I believe the sound is transmitting through the return pipe and into our bedroom. We also hear a loud shuttering sound when the burners shut down, which I think is also being transmitted through the return line to our room.
I recently framed an enclosure for the boiler and water heater and insulted the wall cavities with safe n sound insulation. The shuttering noise at burner shut down is muffled in my daughters room and still just as loud in our bedroom.
I have two remaining ideas on how to possibly address this issue and would like feedback of other ideas. (1) convert our return line to PEX. Hopefully PEX will let out some noise. (2) secure the return branch that has the three zone valves on it. Right now that 1.5 copper pipe and the three returns for each zone move pretty easily and could be more secure. Might cut down on vibration from the shuttering and therefore noise, but since we can hear the gears closing, even if burners haven't fired, I'm thinking this is simply a sound transmission issue through the pipe to our room so PEX may be best bet.
Any ideas would be greatly appreciated.

First things first....I hope you accounted for combustion air in that enclosure. If not done correctly you can create a dangerous situation. As for the noise, I'd insulate and secure the pipes. If that doesn't work, the pex option is still available.

That's what came to my mind as I was reading the post. I'd say you should calculate the cubic feet of air in the boiler room and see if it's enough.

Thanks to you both. The boiler made the noise when it was in my wide open 1200 sqft unfinished basement. I used 48inch louvered doors on the enclosure. So airflow should be fine. I'm gonna try securing the return lines and have a 20 ft piece of pex I'll try. Maybe the noise will escape the plastic versus the copper.
