Air circulation by heat alone: Simply place the double fan on the hot surface of your Swedish stove. The heat gets the rotors going. And the stove heat is already distributed in the room instead of just being lost upwards! So you save heating costs and fuel.
Electricity-free operation with thermoelectric energy: Thanks to the Peltier element, the fan uses only the heat from your fireplace or stove. The hotter its base, the more energy moves the fan blades. So it does not need any external power supply or battery. And you won't incur any extra costs!
Integrated overheating protection: a contact plate in the base expands when the heat is too high. Thus, it provides a greater distance between the furnace and the fan, so that the latter can cool down. This keeps your fan ready for use for a long time!
Please note: The fan is not suitable for stoves and fireplaces whose surfaces are heat insulated. To start the fan, you need heat (at least 65 °C) from below, with sufficient distance to the wall and ceiling, as well as to other heat source such as the stove pipe.
