No it's physics! This fan uses an innovative thermo-electric device to generate electricity directly from heat to run the fan. The electrical energy is generated from the thermal energy flowing through the device from the bottom (hot) portion of the fan stand to the top (fan-cooled) portion of the stand. The effect was discovered in the early 1800s and while it is used rarely today, wood stoves offer a uniquely large source of thermal energy, making powering a wood stove fan a perfect situation for the technology.

But most of all—regardless of how it works—it is effective!

Yes, it can! The fan works on any surface that gets hot enough to cause it to generate power for the fan motor.

The base of the fan just needs to get to around 180F+ degrees to move significant air, though the hotter it gets, the more powerful the fan rotation will be.

If the design of your stove is such that it produces a hot surface on which the fan can be set, it will work great! If you have a grate, insulation, multiple layers on the top surface, it is less likely to be a good option, but you could try to measure surface temp (eg, drip a drop of water on it at full temperature to see if it boils would be one easy way) to see if it's a good solution.

If you have a larger space requiring more circulation power, you might consider getting two fans though of course it is not necessary. About 20% of our customers get 2 fans and many report being glad for it.

The fan won't hurt any fingers, once you touch it, it stops. There's no feeling of a powerful motor driving it.

The fan works on temperature differences to create its own electricity; no battery needed.
