Dual motor design makes the motor more durable and lasts longer, the upgraded model of the stove fan works more efficiently and has a larger airflow. 【No Batteries or Electricity Needed】 Our Wood Stove Fan is powered by heat generated from the stove. When the stove temperature reaches a certain range, the stove fan will start rotating automatically. Through the rapid rotation of the stove fan, the warm air will circulate quickly in the room, making you feel warmer. Tested and proven to save you up to 18% in fuel with more efficient distribution of heat from your wood stove. 【Overheat Protection】 The bottom of the stove fan is equipped with a dual-metal safety device, which slightly lifts the edge of the fan when approaching the highest operating temperature to protect the center module and motor. When the temperature decreases, the fan will automatically return to normal. This will extend the service life of the motor. 【Ultra-Quiet Motor Operating】 As the blades are the only moving components, even at the highest speed, the operational noise of the log burner fan is lower than 25db.
