Eco-friendly - heat powered, no batteries or electricity required. To make the most of the heat from your stove, fireplace fans are designed to spread the heat throughout the room. Reasonable heat circulation, no more moving to the fireplace, no more bothered by the cold!Automatic silent operation -- When the temperature of the hearth reaches 40C, the fan starts to rotate automatically. 80-345 is the normal operating temperature. The higher the temperature, the faster the fan spins and the better the ability to diffuse the heat! It should be noted that the whole process is silent (less than 25db), even if you rest next to it, it will have no effect! High efficiency - The large sawtooth-shaped heat sink helps to dissipate heat more efficiently. When the temperature reaches about 40C, the blades rotate and the heat diffuses directly into the environment without moving up and down. Stir the heat to every corner of the room faster and more efficiently! Ergonomically designed - The hard material base can withstand temperatures up to 500 / 932F, no need to worry mixture during operation. The back is equipped with a baffle to avoid direct exposure of the PCB, safe and beautiful! The small handle of the fan is easy to carry without any effort!BEST OF WINTER - Winter means the arrival of cold weather. If no heater is installed, our wood stove fans can easily distribute the heat from the stove throughout the room. Bring warmth to every corner of your life, no longer trapped by the cold! The best for winter!
