Stove fans like the one in this kit are self-powered, made to place on top of your traditional wood burning or solid fuel stove. It quickly warms and will help distribute heat around the room in near silence. It disperses the heat further from the stove, and is ready to use out of the box. The thermometer attaches to the stove by magnet. Monitor the temperature and you’ll be able to make the most of stove fuel during the evening. You can clearly see when your stove is at the optimum temperature. What a satisfying thought.
