These fans do not use batteries or mains power. Improved warm air circulation results in greater comfort and less fuel consumption.Increased Efficiency:Warm air is circulated directly into the living area rather than having most of the stoves heat rise immediately to the ceiling, thereby increasing the heating efficiency of your stove.Unique Blade Design:The unique anodised Golden or Nickel colored blade has been specifically designed to deliver a very broad cross section of gentle air movement instead of a small cone of concentrated air.Easy Operation:Stovemate Fan starts automatically and adjust speed with the stove's temperature. As the stove heats up the Stovemate Fan runs faster to move more air into the room. As the stove burns down and cools, the Stovemate Fan automatically slows down and stops.Costs Nothing to Operate:Stovemate Fans use only the heat from the stove. The Stovemate Fan is the most economical way to efficiently circulate warm air. It does not use any batteries and can be used where there is no electricity.Stovemate Fans are made from anodised Aluminium that will not rust.
