< li > Environmentally friendly < / li > < li > Thermally powered, without battery or power supply. Taking full advantage of the heat from the poles, the fireplace fans are designed to spread heat across the entire mountain. Rational heat circulation, no more moving around the furnace, no more cold weather! < li > < li > Automatic muffler operation - the fan starts automatically when the furnace temperature reaches 40 C. 80 - 345 C is the normal operating temperature. The higher the temperature, the faster the fan speed and the stronger the heat transfer capacity! Please note that the entire process is quiet (less than 25 DB) and if you rest on the side, there is no effect! < Large-surface serrated radiators have higher heat dissipation efficiency. Li > < li > When the temperature reaches about 40 C, the blades rotate and the heat diffuses directly into the environment without the need to increase or decrease. Heat faster and more efficiently in every corner of the peak! < Li > < li > Ergonomic design < / li > < li > The hard carbide base can withstand temperatures up to 500c / 932f without melting during operation. A fast conductor blocks the circuit boards, directly exposes, SR and beauty! A small handle on the fan is easy to carry without effort. Without heating, our wooden pole fans help spread the heat from the poles all over the mountain. Bring warmth to every corner of your life and no longer be caught by the cold! The best gift of winter! < Li >, "
