Installing Hydronic Floor Heat
New Year's Eve was spent installing Pex tubing into thermal heat plates fastened to 5 1/4" "sleepers" (3/4" plywood strips screwed down between the Pex valleys). The tubing is laid out on 6" centers which is closer than usual since it is in a bathroom, and the curved return Pex boards were found at "Radiant Engineering" in Montana.
We decided not to use the thicker; extruded metal transfer plates which were much more expensive, because having more metal surface on the floor like this is very efficient with 1/4" Wonderboard on top. Silicon was used under the Pex tubing for a more solid install. Happy New Year!
