The rotating mist inflates the hot air from the fireplace to the living area, increasing air circulation in the room and improving the heating efficiency of the stove. The rotation speed depends on the temperature of the heated furnace. When the temperature is higher - the propeller rotates faster when the furnace expires - the propeller slows down until it stops completely. THE SECRET OF OUR FAN? The fireplace fan uses a temperature difference to generate warm air from a heated fireplace. It works automatically thanks to the bimetallic strip, reacting to the temperature without the need for batteries. It is not only an additional source of heat, but also less wood consumption. It starts working at 50C and works up to 345C, which translates into convenience and effective use of wood in colder days.
