Welcome! Here are some tips for using this forum.
When I install a boiler system, I mount my copper to unistrut with standard copper strut-clamps. If the piping wall is common with a room in the house, there will be a problem with pump vibration noise. I've tried placing little rubber squares between the unistrut and the wall that it's attached to. That doesn't work very well. A long time ago I used B-Line insulated clamps. Those didn't really keep the noise away either. It would be great if I could mount vibrationless pumps, but I don't believe they exist yet. I could mount a large sheet of rubber to the wall before piping the system, but that sounds expensive. What creative solutions have worked for you?
