I'm refinishing a Canadian basement and I need to decide where to put the heating vent in each of two rooms. The simplest thing would be to set them in the ceiling. I plan to insulate the ceiling with R12 and then cover it with acoustical tile. I'm also putting a return vent at floor level in the opposite corner of the larger room (there's no easy way to run a return vent to the furnace from the small room).
Obviously the walls will be insulated. The floor is OSB on sleepers, open at one end to provide air flow (and I may cut some floor vents at the opposite end to improve the flow).
Will this be adequate, or is it advisable to run the heating ducts down the partition wall and place the outlet vents near floor level? This would require a "bump" near the ceiling in each room, to get the duct down from the joists and into the wall, so I wouldn't do it that way unless there were a significant advantage.
