2 story house. Stove is in livingroom. Planning of putting small vents
in the ceiling to vent warm air into 2nd story rooms. Should I
approach this as a warm air furnace circulation? Ie: circulation will
only occur when there is a return for cooler air upstairs (cold air
falls)? Plan is to put this vent in the hall ceiling outside the
livingroom. Would I need some small inline fans for either the ceiling
vents or the return? Currently I have a fan in the livingroom doorway
that does a poor job of blowing warm air out the door let alone
sending it up the stairwell to the second floor. Ceiling fans (3) on
second floor do not help either.

Thanks
