Return Air Vents high or low?
I am working on a reno/addition in CZ 6. The homeowners friend is the Mechanical Contractor on this job. The heating system is an outdoor woodburning forced air with LP back up. He installed the return air vents in the wall cavity ,but they are only 1 inch above the floor. I feel he put in the minimum return air vents. And at the floor? He claims that this method pulls the heat down from the ceiling and warms the room. However in one location there is a heat duct within 5 feet of the return air vent both at the floor. Our walls will have R-31 (2" EPS with 5.5" dense pack cellulose) and >R-50 in the ceiling. Is this a good idea for return air vents?

Any experience with an unheated (but insulated) slab as a finished floor? Will it be uncomfortably cold?
