copper staple up

Are you thinking copper in aluminum transfer plates? Or copper directly against the subfloor?
The biggest obstacle is the expansion of the copper. It is going to grow in length and will need someplace to move. If you use a tight fitting plate like the ThermoFin the tube will not move in the plate, but the whole plate will want to expand or arc. I've heard stories of the movement actually shearing off the fasteners!
I have done a few copper in plate applications.. keep the length short, and loop them together with pex or something to allow some movement.
The other thing would be to use constant circ so you don't have a wide and quick temperature change.
Last but not least warn the owner of some potential noise issues.
If they insist on copper you might consider joist bay warming with baseboard element or Ultra Fin, depending on the loads of course.
Stay tuned for some infared pics of an UltraFin job I watched work this past week.

I have a client interested in a retro-fit radiant job. He is requesting that I use copper pipe instead of that "new fangled" plastic stuff. Has anyone installed a copper staple-up application, and if so what problems were encountered? Before I walk away from this one, I want to be sure I am well informed and can relate this information to the client. Maybe I am not seeing the forest for all the trees that are in the way? Your input would be greatly appreciated. Grumpy0 -
Isn't that Ken's installation method
He used copper exclusively, didn't he?
