I have had problems moving the air around the house (2 story/2400 sq.ft) .. used regular fans to minimal effect.
This year I got an inline booster fan, see link. I put in small nails into the top of my doorway casing and strung or hung the fan using some picture wire (running wire through the "tube" of the fan).
Now the top level is only 2-3 degrees cooler than the room with the fan ... and the fan is pretty quiet. And the rooms on the first, furthest from the stove (not an open concept floorplan) are also 2-3 degrees different than the room with the stove. (measured at furthest point in room from stove).
So its 28 outside, 70 in room with stove and 68-67 elsewhere. (the furthest bedroom from the stove upstairs is only exception being at 64..its down about a 20 ft hallway ... so I am not surprised at this).
