1、HOW IT WORKS: The wood stove fan provides heat from the wood burning stove, the heat sink convert the absorbed heat energy into kinetic energy, and when the temperature reaches 80‑250℃ (176℉‑482℉)(the best operating temperature), the wood stove fan start to transfer warm air horizontally around your house, the air volume is 280‑330m³/h. Maximum operating temperature 350℃ (662℉) 2、NO DEFORMATION AND DISCOLORATION: The furnace support is treated with anodized aluminum, which will not deform and discolor even if works for a long time at high temperature 3、RUSTPROOF MATERIAL: 6 blades heat powered stove fan is rustproof, wear resistant, possess good thermal conductivity, can be used for a long time 4、NO ELECTRICITY REQUIRED: The thermoelectric module acts as a small generator to drive the fan motor. No batteries or electricity required. Improved hot air circulation bring greater comfort and uses 28% less wood in the stove, noise level <25db 5、SAFE PROTECTION: The fan base is equipped with a bi metal safety device, if the surface temperature exceeds 300℃, the safety device gradually lift the front of fan to protect TEG and motor
