Expired4-Blade Heat Powered Stove Fan for Wood/Log Burner/Fireplace Increases 80% More Warm air Than 2 Blade Fan- Eco Friendly(Black)

Why do we need to use the stove fan?
Instead of the heat rising vertically with a standard stove, the stove fan uses its blades to divert the warm air horizontally.
The extra movement of air will help warm the whole room, not just the ceiling and the area near the stove.

How is working without batteries or electricity？
The stove fan runs without batteries,cords or electricity, it generates its own power by the heat from the stove surface.
The base of the fan transmits the heat to electricity generating units,and electricity generating units convert the heat energy into kinetic energy to drive the motor,then the blades spin.
The fan spins when the temperature is reached 185 ºF. The hotter the base of the fan gets,the faster the fan turns,and the more air the fan circulates into the room.It will slow down and stop as the stove cools.
The stove fan is designed for usage on freestanding stoves with a normal surface temperature of between 185ºF - 660ºF. Temperatures above this range may damage the fan and the electricity generating units.
