Features Powered by Heat --- The wooden stove fan is powered by heat offered by the wood stove, and the heat dissipation fins convert the absorbed heat into energy. When the temperature gets to 80‑250℃, that is, 176‑482℉, the wooden stove fan starts, transferring wa Effective Heat Distribution --- This 8 blade thermal driven stove fan circulates more warm air, largely facilitating the overall heat distribution. Saving Energy --- The thermoelectric module serves as a small generator to drive the motor of the fan. No battery or power required! The improved hot air circulation can bring greater comfort, and the use of stove wood is reduced, with a noise level of < Safety Design --- Treated with anodized aluminum oxide, which does not deform or change color even when working for a long time at high temperatures. It has good rust prevention, wear resistance, and thermal conductivity. Great Durability --- The fan base is equipped with a bimetallic safety device. If the surface temperature exceeds 300℃, the safety device will gently lift the front of the fan to protecting the TEG and motor.
