I can hear my boiler burner throughout my house. I have found that the majority of the noise transmission is via 2 threadded rod supports that support a large cast iron pipe out of the boiler that turns into a copper pipe converter for my hydronic heat. The threaded rod connects to a clamp ring on the copper pipe and screws into a base that is mounted to the ceiling joists.
Is there a noise absorbing alternative support, or maybe I can make something that supports it form the basement floor (it is in the basement).
Any help would be appreciated.
