Strong Magnet, Easy to Install - This magnetic pellet stove fan uses two heat-resistant magnets for a firm attachment to the chimney pipe, saving space. An additional iron ring increases stability or allows mounting on non-ferrous pipes. No Battery or Electricity Required - Our wood stove fan without electricity works by heat, no electricity needed. Automatic start at a temperature of 100°C (212°F). Use the heat from the chimney pipe optimally to distribute heat to every corner of the room and achieve more efficient heating with less fuel. Save wood or your gas bill. Quiet Operation - Our thermal fan operates almost silently, despite an impressive rotation speed. You will feel the heat without even noticing that the fireplace fan is there. Just enjoy the warm air in a quiet and comfortable environment. Attention: If the pellet stove flue temperature does not exceed 80°C, the fan cannot reach its optimal performance. If the temperature is too low, the fan may not work. Note: The data
