Here's what I've done so far.
There is no insulation in the floor joists. It's a raised ranch and I do have a 1 car garage below the living area(the living area is the coldest part of the house).
Last year I put a 6" to 8" duct coming out of the top of the stoker. I put a booster fan in the 8" register. Then a put a T into 2 6" ducts each with their own booster fan. Each 6" duct is run into our 2 bedrooms. This year, I was thinking of putting in 2 separate line voltage Thermostats for the booster fans to the bedrooms so when the temperature warms up it doesn't get to 90F in the room again (woops)
I leave the door to the basement open and I cut a vent in the hallway floor to allow the colder air to drop back down to the basement.
This worked OK for the bedrooms, but now that my wife is home with a baby, I need to keep the living room/kitchen warm as well.
I like the idea about running a duct from the farthest point down to the intake of the blower fan. I think this might be the missing piece to my problem.
Let me try to put together a floor layout and let you guys debate on the best heating method for my house.
