I got the Ecofan off Amazon (2 blade) for $79 and free shipping. Got it today, set it on the Hearthstone stove on the back left corner, angled it toward Mrs. UTS. It does move the air towards her little corner of the world.
It is amazing to watch, as Steve A says earlier, it is nice to see something work as advertised.
And an apology to our webmaster. I was following a series of Google links, ended up on Amazon and ordered the fan. As I hit the last enter button, I realized I could have accessed Amazon from this website and helped Don out. Sorry Don...(insert picture of Upthesaukee with his head hung down)
Oh, and the Heat Fans are no longer being manufactured as of Jan 2009.
