Rather, this is designed to distribute the heat through the room. Here's the difference: when you use the electric blower fan on a woodstove you feel a breeze as you stand in front of it. With this heat powered fan, you don't notice the breeze but feel the overall room temperature rise, regardless of proximity to the woodstove.
