I am going to try a similar thing but use sand and clay mixed for the mass.

Craig, I suspect without insulation under the reflective side and the additional 1-1/2" of wood on top the you may not see the performance you may like to see. You may have to run hotter water, but with an wood boiler it may not be so much of an issue. Wood not being a real good conductor of heat, bordering on insulation itself.

I am going to use narrow board, 4" or so, wide.

I have thought of not covering the clay/sand mix, too, maybe in the bedroom. Less traffic.
