Stove Fan Wood Stove Fans Fireplace Fan Heat Powered Fan With 4 Blade And Digital Temperature Display Product selling point: Isn't there a fireplace? Why do you still need a fireplace fan? Because the heat of the fireplace is rising, and the fireplace is surrounded by heat. The function of the fireplace fan is to blow the rising heat horizontally so that the whole room can enjoy the warmth. Heat Powered: Heat powered wood stove fans power by converting the heat from stove into electricity, electricity generating units the heat energy into energy to drive the motor, then the blades spin.No batteries or electricity required,. Large Volume: Diffuse warm throughout the whole room. Just place the stove fan on a smooth flat surface of your stove top ,near the side or back of the stovepipe. Need to place stove fan at least 4" away from stovepipe. It will work when the stove surface hot. 50C(122F)-340C644F) Working Temperature: The wood stove fan spins when the temperature is reached 50C(122F).The hotter the base of the fan gets, the faster the fan turns, and the more the fan circulates into. It will slow down and stop as the stove cools. Temperature Digital Display: The function of the temperature digital display on the fireplace fan: it is used to monitor the real-time temperature of the pattern, to avoid the risk of scalding during operation and the risk of burning the fan due to too high temperature. The corresponding operation is made according to the actual temperature, because the heat is enough, In the process of heat dissipation, the temperature of the pattern will increase with the time of use and the continuous addition of firewood. If the heat source temperature is not high, the heat dissipation and heat absorption of the flower pattern a balance, so it is not necessary to test the point). The heat source of the product test is about half an hour at 250 (482 ), and the pattern temperature reaches equilibrium at 45 (113 ), and the pattern temperature does not increase. Test Values Of Temperature Digital Display: Digital display 30 (86) fireplace top temperature 200 -220 (392-428), digital display 45 (113) fireplace top temperature 230 -290 (446-554), digital display 50 (122) furnace top temperature 290--370- (554-698), digital display 55 131 indicates that the temperature of the hearth has reached 380 - 400 (716-752). The fan is in danger of burning out, so it should be removed and cooled as soon as possible. Aluminum Material: Stove fan is made from anodized aluminum, which will not rust or corrode when the fan is getting hot. Protection Function:There is a iron sheet on the fan bottom, with the increasing of temperature, the iron sheet will to the fan from damage.
