Durable construction: made from longlasting aluminum alloys for stable, lowmaintenance performance in temperature conditions. Automatic, reliable operation: the fan begins working at 140 F (60 C) to start moving warm air from your stove as soon as the surface is hot enough. Builtin overheat protection: autoadjusting metal strips protect internal components during extreme temperatures, extending the fan's service life and preventing damage. Accurate temperature monitoring: the included surface thermometer measures stove temperature from 80 C to 350 C, helping you operate safely and optimize fuel use. No electricity required: this heatpowered fan converts stove heat into circulated warm air without power cords or batteries, lowering operating cost and improving safety. Improved heat distribution: the fan efficiently circulates warm air and optimizes wood stove heat distribution (6 optimizing design), making heating more even and effective across the room. Compatibility and performance: Works with masonry heaters, cast iron stoves, pellet stoves and similar solidfuel heating appliances. Ideal for improving comfort and fuel efficiency on any stove with a sufficiently hot surface (activates at 140 F / 60 C). Practical use scenarios: Living room: place on a castiron wood stove to push warm air into the room on cold nights without electricity or noise from electric blowers. Workshop or garage heated with a pellet stove: circulate heat more evenly to reduce cold spots and maintain a safer, more comfortable workspace. Masonry heater: monitor surface temperature with the included thermometer and let the fan distribute stored heat efficiently throughout adjoining rooms. Why customers choose this fan: Simple, maintenance operation—no wiring or batteries required. Builtin safety features (autoadjusting metal strips and precise surface thermometer) help prevent overheating and improve fuel efficiency. Sturdy aluminumalloy construction for reliable, longterm use with wood, pellet, and masonry heating systems.
