Stale thread (OP was last heard from 7 months ago), but a perennially applicable and talked about topic. My experience fully supports Mike's advice...do what you can to move cool air down low toward the space heater, and it will be replaced by warm air up high. Ceiling fans are wonderful for mixing (destratifying) the air in a room (as can be a blower kit on a freestander), but do little to move air sideways to other rooms. It's a challenge we all face to one degree or another. Rick
