Laying down the hydronic tubing

This is not an initiatory ritual of an ancient Greek mystery cult, nor is it a scene from the Lord of the Rings (with Alex starring as a Hobbit and me acting as an Orc). This is Alex and me on April 14 laying the tubing for the hydronic slab. Alex is tying down the tubing to a wire mesh using plastic ties. The tubing is somewhat unwieldy, so you need a second person to hold and unroll the tubing. Also visible is the polyethylene vapor barrier to keep the humidity away from the house interior, and the Styrofoam board used to insulate the outside perimeter of the floor.

The tubing is attached to the slab manifold, shown here. Hot water will be distributed by the manifold from the hot water tank to three loops that snake throughout the concrete floor. Here, only the first loop and the outflow of the second loop is attached to the copper tubing of the manifold.

My Dad has a whole bunch of pictures of the finished layout that I'll post later.
