Upgrade 4-Blade Wood Stove Fan, Heat-Powered Chimney Fan for Wood Stoves/Fireplaces, Quiet Fan (Black)

【BETTER HEAT DISTRIBUTION】: This 4-blade fan is designed to provide a very wide heat current from the combustion in your fireplace or stove, so it can quickly raise the temperature of your room and keep it warm. The hotter the stove, the wider the fan can circulate, with a maximum warm air transmission distance of 3 meters. 【OPERATES QUIETLY】: The only moving part of the heat fan is the set of blades, so the operating noise is less than 32 dB, making it very quiet. It distributes heat throughout the room with minimal noise, improving warm air circulation. You won't even know where the fan is, but you'll feel the warmth! 【ECO-FRIENDLY AND ENERGY-SAVING】: No batteries or electricity required; the fan automatically activates when the stove surface temperature reaches 70-110°C (depending on the chimney type). The only moving part is the blade attachment, making the wood stove fan almost completely silent even at maximum speed. 【TEMPERATURE DISPLAY】: The top of the fan is equipped with a temperature display strip. The fan will only start operating when the temperature reaches 70-110 degrees Celsius (depending on the chimney type). 【SAFETY PROTECTION DESIGN】: The stove fan comes with a bimetallic safety device. When the stove surface temperature exceeds its maximum operating temperature, the safety device gently raises the front of the fan to protect the central module and motor.
