A wood stove fan can help circulate the radiant heat produced by the wood stove, greatly increasing the efficiency of the wood stove. In deciding what type will provide the best performance in your situation, consider electric fans and blowers, as well as passive equipment operating heat-generating furnaces. Furnace tube heat recuperators are attached to pipes above the furnace to remove and circulate heat that would otherwise go into the chimney. The wood stove fan option should not be confused with the chimney fan, which is designed to increase the ventilation volume and efficiency of the wood stove.
The common wood burner fans for sale range from inexpensive models that simply drive radiant heat away from the furnace, to more complex designs that provide more control over temperature, the amount of heated air, and in some cases the direction the heated air moves. Some models include thermal sensors that control fan speed through rheostats, which provide more power when cooling. Aftermarket devices that you can plug into a wood stove fan can also be used to control fan speed and noise. If you need to transfer heat from one room to another, there are dedicated fans installed in doorways or walls to improve heat circulation.
The furnace tube heat recuperator also helps to circulate the heated air while exhausting less heated air to the outside through the flue, increasing the efficiency of the furnace. The reclaimer contains one or more heat exchangers to extract heat from the flue gas moving above the chimney. A fan, usually thermostatically controlled, pushes hot air into the room. Various models are available for different furnace tube sizes. They are usually significantly more expensive than simple fans and blowers and often require some expertise to retrofit them to your furnace, as well as a conveniently located electrical outlet.
It may not move as much hot air as an electric fan, but it has the advantage of quiet operation and no need for a nearby power outlet. Many passive fans for woodstoves are designed to enhance your decor with attractive designs and materials. Recent models of unpowered wood stove fans take advantage of a phenomenon called the Peltier effect. The fan spins faster when the furnace heats up, then slows down as it cools.
Finally, as a professional woodstove fan supplier, Toposon would like to remind users that one should never install ordinary exhaust fans on the fireplace chimney. They will be corroded by the high-temperature combustion exhaust gas, which may cause a malfunction and stop working. In addition, ordinary exhaust fans are not specially designed for wood-burning fireplaces. Their rotating speed is too fast and the generated drawing force is too strong, which can easily cause the fireplace to be over-burned and scrapped, or even cause a fire. Remember: Professional use requires specialized equipment.
