The standard fan cools down your room on warm summer days. The stove fan does the exact opposite. It does not cool down the temperature, but heats it up. The rising warm air from the stove is optimally distributed in the room by the rotating movement of the individual blades of the fan.
The way a stove fan works is quite simple. It is based on the principle of thermoelectricity, which means that you do not need electricity or a battery. A thermocouple is built into the bottom of the stove fan. As soon as the stove burns and thus generates heat, this thermocouple heats up.
The result is that the lower part of the fan is much hotter than the upper part. In addition, both areas are equipped with a different material so that a temperature difference can be created.
This temperature difference is used to create heat conduction through electrons. This means that there are many electrons with high energy at the bottom of the fan. At the top end, it is logically the other way round. The electrons with a lot of energy want to go up and the electrons with little energy want to go down. This interaction creates a voltage inside.
This tension is now responsible for the wings moving. These wings, on the other hand, ensure that the rising heat from the stove is distributed in your living room. The more hot air there is, the faster the blades turn and the better the heat is distributed throughout the room.
