Feature:1. [Heat Powered] The use of thermal power as an energy source does not require the use of batteries or electricity, which can efficiently circulate warm indoor air.2. [With Thermoelectric Module] There is a thermoelectric module on the fan, which acts as a small generator to drive the motor. When this generator module experiences the difference in heat between the top and bottom surfaces, an electric current is generated. The top of the module is kept cool by the top heat sink of the fan.3. [Improve Circulation] Put it on the burning stove, it will absorb the heat energy to drive the fan to rotate, thereby blowing the hot above the wood burning fireplace directly to the living area, increasing the circulation in the room and improving the heating efficiency of the stove.4. [Rotation Speed Adjustable] The rotation speed of the fan depends on the temperature of the furnace. The higher the temperature, the faster the speed. When the furnace temperature is low until the fire is extinguished, the speed will slow down until it stops rotating, and the factor is high.5.
