On top radiant heat

Hub

I want to use radiant floor heating in a new house that's rather large. I want to install it myself, and have contacted several suppliers. Right now, my intention is to install the tubing above the sub-floor, with 7" wide strips of wood spaced 3/4" apart. Obviously, the aluminum plate and tubing will fit into the slot created by the 7"wide strips. I plan to cover this layer with plywood, then the floor covering, some of which will be linoleum, and some....... carpeting. The reason I want to use the wood strips is because I have an unlimited supply of 3/4" lumber already in my possession. The cost was perfect........... free!! Is there any reason not to do what I've described? I'm well experienced in construction, plumbing, and electrical work, but having never done this type of project before, I'm looking for advice.
