As the hot air rises, most of the stove's heat escapes directly from above and gathers around the ceiling. Without a stove fan, you have to wait a long time to feel the heat. This stove fan is designed to provide the quietest and most efficient heat cycle to remove all heat from the stove heater. The heat from and around the stove is pushed around the room and we can feel the heat faster after the fan improves the heat circulation. We provide premium stove solutions of superior quality and inspiration, bringing more comfort and warmth to people all over the world.
