【Family Essentials-Fireplace Fan】Working Principle- The hot air stove fan is designed to circulate the warm air generated by the wood/coal or pellet stove operating at the normal surface temperature between 60°C and 350°C. The stove fan is placed on the fireplace pipe, using the temperature/heat transferred from the fireplace to generate electricity and drive the fireplace fan. 【Efficient Heat Distribution】 The stove fan can promote air circulation, evenly distribute warm air throughout the room, improve the circulation of hot air and prevent heat dissipation. Less consumption, more efficiency, the stove fan will help reduce fuel consumption and quickly warm up the room. 【Quiet Operation】 The only moving part is the newly designed blade assembly. You don't even know the stove fan is there, but you feel the heat! With larger air volume and less noise, you will enjoy warm air in a quiet and comfortable environment. 【No battery or electricity required】 Environmental protection and energy
