I learn't from this forum about pushing cool air towards the stove ,I used one in the small passage and it worked wonders with the downstairs.Last night I used one at the top of the stairs pointing down...WOW what a difference,The cabin is 1400 sq ft half up half down with the master bed ,bathroom and media room upstairs I couldn't believe the difference it made, the whole house seems to be the SAME temp now .It is good to never stop learning stuff.
