Noise transmission thru copper pipe supports
 

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.

of a commercial product as structure-borne sound transmission is more
problematic in concrete and steel buildings.

The problem is that you're not guzzling enough beer or you wouldn't
hear it...... :)

I'll second the muffler (exhaust pipe) hangers. If you cant find
large enough ones, make them. Use some of that heavy punched metal
strapping used to hang garage door tracks, and bolt in rubber strips
cut from junk tires. A good recycling project. Use several layers of
the rubber if needed. As for the part that clamps around the pipes,
use what you already have from your current hangers. When you bolt
thru the rubber, be sure to use large washers so the bolt dont pull
thru it.

It should look something like this:

This is a bit on the radical side. The muffler clamps suggested will
work, but you can also take some automotive type V belts, loop them
around the pipe and then attach the top of the belt to the
rafter/joist. The belts will last a very long time (being fiber
reinforced) and will absorbe most of the vibrations easily. The
biggest down side is that when someone sees it they'll think you are
nuts until you explain how well it works.

Less ugly, but takes only a bit more work is to use some 1 or 2 inch
webbing (like on automove tow straps) and use that as a hanger. Down
side on this is it is more difficult to attach the webbing to the
joists/rafters (you can't just punch a hole for a bolt, but must use
several nails that go between the fibers/threads and use a backing
plate to prevent the nail heads from pulling through. (Roofing nails
work well in this case.)
