We have a basement install and have been using a short pedestal fan to move the cold air down the stairs. I had put some shims under the back to angle the fan down the stairs but couldn't get it angled enough without it tipping over with the slightest bump. Thinking I could do better, I purchased a small fan at WalMart that the fan pivots on the supports and I can get it the exact same angle as the stairs. A huge difference! I can't believe how much heat you can feel moving up the stairs.
