1.[Dual Motors and Dual Large Blades] heat powered stove fan is equipped two motors that drive two large blades to rotate back and forth. This makes the fan almost twice as efficient as other wood burning stove fan. Compared to other dual-motor woodstove fans heat powered, the blade size is larger, which makes its air volume larger than other dual-motor fans. 2.[Heat Powered & Higher Energy Efficiency]The working principle of the heat fan for wood stove is to use the thermoelectric conversion module to convert the heat energy of the fireplace combustion into electrical energy. The design structure of the dual motor and dual blades allows the stirling engine stove fan to absorb double the heat when working, which will greatly reduce the waste of heat generated by the combustion of the wood stove, thereby improving energy utilization. built-in high temperature overload protection device. Once the temperature exceeds 350 degrees Celsius, the shrapnel on the fan base will automatically pop up, reducing the surface between the fan base and the wood stove, thereby reducing the heat transfer. The sound of the fan for wood stove powered by heat during operation is always less than 25 decibels, which will not cause any impact on your life or work. 4.[Less Consumption]'s thermoelectric fan does not consume electrical energy. The winter cocoon fan for wood stove works by absorbing the heat from fuel combustion, accelerating the circulation of warm air in the room. This speeds up the heat circulation in the room, making the room warm faster and longer, thereby reducing fuel consumption. 5.[Warranty and After-s], as a professional wood stove fans non electric Brand, has cooperated with more than 200,000 buyers.
