I have the small version of that heat driven fan. It is cool looking and it does circulate a little air, but it was expensive and I feel I could run an efficient electric fan 24/7 for several years at about the same cost. I have a jutul stove and there is no rear mounted blower available so I just use a few fans plus the little heat propelled one and I feel it does a good job although there is room for improvment. The trouble with running fans, even on low, is I have trouble hearing the tv, and since we have a 2 year old who sleeps directley above our polar, I can't turn it up too load.:bang:
