It is a small fan that goes on top of a wood stove that operates by heat. The hotter the stove the faster it goes. We are thinking about geting one and wanted to know who has tried it. It moves like 100 cubic feet of air per minute.
Well our stove has a fan or blower and works great. The ecofan uses no electricity and is very quiet. As a matter of fact, it make no noise at all which is better than listening to the blower on the stove.
