This is kind of a silly question, but what is the best way to attach the piping, valves, pumps, etc. for a radiant heat system to the wall?
I put up a sheet of 3/4" plywood on the wall as a base and have the boiler attached to the studs through the plywood. The majority of the pipe is 1" copper and the pump requires about 2" of stand-off for the flanges to clear. I purchased some copper bells for the pipe, but they only provide about 1" of standoff.
I can put a small piece of wood behind the bell to get enough stand-off, but was hoping there was a more elegant solution.
