Kafei Fireplace Fan | 6-Blade Heat Powered Wood Stove Fan | Thermodynamic Wood Burning Stove Fan for Wood Log Burner Fireplace

Features: 1. Automatic adjustment: the fireplace fan can be automatically started and the speed can be adjusted according to the temperature of the furnace. 2. Low energy consumption: low consumption high efficiency can increase room temperature by 41% and save energy cost by up to 16%. 3. No Batteries: Your stove s thermoelectric fans don t use batteries or electricity to improve your stove s heating efficiency which allows warm air to flow through your room faster. Specification: Name: Fireplace Fan Model: BLFS Colour: Black Power supply equipment: thermoelectric module (thermal power supply) Material: Aluminum Airflow: 203CFM Initial temperature: 40℃ Working temperature: 50-400℃ Noise level: 15-18db Recommended distance: about 10-15CM/3.93-5.90IN Product structure: metal handle 2. heat sink 3. bimetal heat insulation device Working principle: The thermoelectric furnace fan uses thermoelectric technology to convert the temperature difference into electrical energy. There is a unique thermoelectric module in the center of the fan. When heated the module will generate hot and cold sides allowing electrons to flow into the module and generate electricity to operate the fan which is also called the Seebeck effect. Notice: The furnace fan does not bring about a direct temperature increase but is only a tool to accelerate heat transfer from the chimney. Make sure the stove fan is placed on a flat surface.
