Moving air from first floor to second floor...CFM?

[hpfreak]

I installed a wood stove in my first floor living room. The temp in this room easily gets in the mid-80's with even the smallest slow burn fire, while the rest of the house hovers around 75 on the first floor and 70 on the second.

Finally to the question..

I am installing a duct in the cieling that will vent from a second floor wall. APPROXIMATELY How many CFM does the blower need to be rated in order to even out the temperatures? The house is 2000 ft2; 1000 upstairs and 1000 downstairs.

I'd say between 100-15,000 cfm.. approximately.

It's a hard guess without knowing more about the setup. How big is the house? Where are you in the world? How big is the wood stove?

If I was to 'rule of thumb it' I would say that 4 ACH would help average out your house (move 4 complete volumes of air from the hot area each hour).
