[Heat Use] :This stove fan of ours uses the principle of heat power by drawing in hot air from the back of the fireplace and generating power to push the hot air forward through the heat sensitive motor inside. This allows the hot air to circulate better in the room and improves the thermal efficiency of the fireplace[Automatic Activation]: The stove fan uses a thermal motor which automatically starts and stops depending on the temperature of the fireplace. When the fireplace temperature reaches a certain level, the fan will automatically start and begin to circulate hot air. When the fireplace temperature drops, the fan will automatically stop, saving energy and extending the life of the fan.[Low Noise Operation]: This stove fan has a silent design and runs at a low noise level, which will not disturb the indoor environment and users. Create a comfortable and quiet environment for you[Energy Savings]: By enhancing the circulation of hot air, fireplace fans increase the thermal efficiency of the fireplace, allowing heat to be transferred to the room more efficiently. This means that the fireplace can produce the same amount of heat at a lower temperature, thus saving energy and reducing energy consumption5.[Easy Installation]: Stove fans have a simple installation process that allows them to be quickly installed on top or on the side of the fireplace without the need for complicated remodeling or installation work. Users can easily use the fan with their existing fireplace to improve the comfort and thermal efficiency of the fireplaceProduct specifications:Material: Anodized AluminumStarting temperature: 70C (158F)Maximum operating temperature: 345C (653F)AirFlow: 80-170CFM (cubic feet per minute)Noise:
