Easy to Operate - The stove fan starts automatically and adjusts speed with the stove’s temperature, moving more air at higher temperatures and slowing and stopping as the stove burns down. Designed for a Variety of Fireplaces - Whether you have a multi fuel or wood burning stove, our Cosystove fan will work with the same efficiency to deliver you the same great performance. Unique Blade Design - The unique anodised blade has been specifically designed to deliver a wide section of gentle air movement rather than a small concentration of warm air. Ultra Low Starting Temperature - The Cosystove 4 blade fan starts heating your home in minutes with a starting temperature of 65°C and will keep working up to 345°C. Eco Friendly and Economical - By circulating warm air directly into the living area, this fan allows you to burn up to 14% less wood saving your money and the environment.
