Description: This Wood Burning Stove Heating Fan is silent, directly suspended, easy to use, energy-saving, and has overheat protection. And can be applied to a wide temperature range. Features: 1. Automatic adjustment: the fireplace fan can be automatically started, and the speed can be adjusted according to the temperature of the furnace. 2. Low energy consumption: low consumption, high efficiency, can increase room temperature by 41%, save cost by up to 16%, no battery or power supply, more environmentally friendly. 3. The stove's thermoelectric fan does not use batteries or electricity to increase the heating efficiency of the stove, which allows warm air to flow through your room faster. Working Principle: Thermoelectric furnace fans use thermoelectric technology to convert temperature differences into electrical energy. There is a unique thermoelectric module in the center of the fan. When heated, the module generates hot and cold sides, allowing electrons to flow into the module and generate electricity to operate the fan. This is also known as the Seebeck effect Note:The furnace fan does not bring about a direct temperature increase, but is only a tool to accelerate heat transfer from the chimney. Make sure the stove fan is placed on a flat surface.
