The cheapest way to even out temperatures if the air near the ceiling is noticeably warmer than the air down below is with a fan; it doen't make much difference what kind of a fan you use, nor whether you blow up or down. Just miking the air works fine. And fans draw so little current that you can ignore their consumption; whatever slight amount it is contributes to heating the room anyway. Ceiling fans work well and don't get underfoot.
