How is the tubing installed?
In the basement, the tubing is attached to a mesh or weld wire, and concrete is poured over the top of it. All loops come up out of the concrete into a valve manifold which is then piped back to the heat source. The tubing can also be attached to a pre cast floor and then an additional concrete or lightweight concrete then covers the tubing for a new subfloor. Another method is simply tacking it to the underside of the Subfloor between the floor joist. Or, there are other products that assist in the installation of the tubing.
