Everyone here has one, and many people have two. The house I stayed in last winter had one. So I borrowed one to see for it would work on my woodstove given that I run it at low temperatures.
Well so far it is working perfectly. I moved my stack temperature gage off the stack and next too the fan and it starts at 150* degrees just like they claim.

But what makes it work........? Yes, just the heat. But why....? And I wonder could they make one large enough that it would circulate water in heat systems.
