Features 1. Upgraded Version: Less consumption, more efficiency. This heat-powered stove fan has been tested and proven to save 28% fuel costs, improve warm air circulation resulting in increased comfort, and reduce wood consumption from your stove. 2. Premium Material: The stove is made of high-temperature resistant aluminum, and the bracket is treated with anodized aluminum oxide. The stove is designed for use on freestanding stoves with a standard surface temperature between 60 degrees Celsius and 350 degrees Celsius. 3. Overheating Protection Design: The fan base is equipped with a bimetallic safety device that gently lifts the front of the fan if the surface temperature exceeds 300 degrees Celsius to protect the TEG and motor, ensuring the lifespan of the stove fan. 4. Eco-Friendly: The thermoelectric module acts as a small generator to power the fan's motor, no batteries or electricity required. Thermoelectric stove fans are designed to circulate warm air produced by wood, coal, or pellet-burning stoves. 5. Whispering Quiet: Designed with four blades, larger air volume, and lower noise. The moving part is the blade assembly, so the working noise is under 25db. You will enjoy the warm air in a quiet and comfortable environment.
