A wood burner fan is a device that sits on top of a wood-burning stove and helps to circulate the warm air throughout the room. This can help to improve the efficiency of the stove and make the room more comfortable.
Wood burner fans are typically powered by the heat of the stove, so they do not require any electricity. They are also relatively inexpensive and easy to install. However, it is important to note that wood burner fans can be noisy, and they may not be suitable for all homes.
