Radiant flooring

Inspired by a flooring product I have seen, I developed a home-grown modular track system for installing radiant tubing in the floor of the Cubit. It basically consists of 5/8" pex tubing with strips of plywood 5 3/8" wide, with 6" radius turn pieces at the ends. This allows me to lay the tubing within the subfloor in a zig-zag pattern back and forth along the length of the house. I have yet to decide how I will plumb the system, but I now have the plumbing infrastructure I need within my floor. Yay!
