Closed loop or open, some sort of return is needed. You'd be better having
someone look at the actual layout of hte house nad heating system. In order
to get the hot air into the living space, you have to be able to get the
cold air out. If you have a multi story house, the basement door is
probably not enough for a good air flow pattern.
