Features 5 Blades: Upgraded 5 blades provide a larger air volume, circulating warm air horizontally throughout your house without giving you direct hot wind. The most effective way to heat your room from your stove, commonly used for wood stoves, gas stoves, pellet stoves, and more. A magnetic thermometer is included to monitor the temperature of your stove. Overheat Protection: The built-in bimetallic strip at the base of the stove fan is designed to slightly raise the edge of the fan when the maximum operating temperature is approached to protect the motor and thermoelectric module. Silent Operation: The only moving part of the stove fan is the blade assembly, so the working noise is below 25 dB, very quiet. Spread heat around the room and increase the temperature with low noise, improving warm air circulation resulting in greater comfort and reducing wood consumption from your stove. More stable and environmentally friendly. Safe Material & Longer Lifespan: This stove fan is made of rust-resistant anodized aluminum, durable, with good thermal conductivity. Operating Temperature: Recommended surface temperature is between 45 °C - 350 °C. If the fan does not start in time after the temperature has been reached, move the blade slightly (do not touch it directly with your hands). The maximum temperature that the product can withstand is 350 degrees.
