Radiant heating in walls

[jcarlot]

We are rehabbing an old building and will strip the walls down to the studs and then add foam in place insulation.
We are considering the installation of radiant wall panels or putting up durock or some other wallboard with the tubing between the wall board and the insulation. We would then put a skim coat of plaster on the walls.
We figure the radiant heated wall would extend 8 to 10 feet from the floor.
We could do the floor as well in sections but there will be area rugs on the floor and since it is an old building the floor thickness is already 1-1/2 inch thick.
Any suggestions on the feasibility.The room is 24 X 50 with 14 ft ceilings.

Radiant in walls can be done, but with a couple of restrictions. First, I would not suggest putting it any higher up the wall than 4'. Above that height is where wall hangings normally are, and the risk of putting a nail or fastener through the tube is fairly large. Second, you'll want to limit your water temperature to no higher than 120 degrees, or the gypsum in the wall boards will begin to degrade.

It has a section detailing radiant in walls.
