If you are going to build from the ground up, and got some extra $$$, The only way to go is radiant floor heat in the concrete. Add some glycol (anti freeze) to it and set the temp of the return water to about 105 degrees F. and run the pump on the hot water boiler doing heating continuously and knock the burner off when the return water reaches its set point. Most heatings vendors will spec out your plans, for material needed. If not contact me.
