Bullet Points: 1Quiet Operation: The Wood Stove Fan spreads heat around the room and raises the temperature with low noise, improves warm air circulation for greater comfort, and reduces wood material consumption for the stove. More stable and secure, it has no noise and you can enjoy the warmth of the small wood stove in peace. 2High-Grade Material: No battery or utility power is required, the thermoelectric module acts as a small generator to power the Fireplace Fan. It is made of anodized aluminum, which is rust-proof, wear-resistant and has good thermal conductivity. 3Easy to Use: This Log Burner Fan can be installed on top of any stove or log burner with no setup required. You can simply place it on a burning log and enjoy a warmer room as your fan will circulate warm air using the heat from the log burning stove. 4Widely Applicable: Stove Fan needs heat from the stove fan, without batteries or electricity. This fan allows you to get maximum heat from log burning stoves and is widely used in wood material burning stoves, pellet stoves, etc. 5Suitable for Fireplace: The surface temperatures of the Silent Fire Place Fan are between 122F-644F (50C-370C). If the fan does not run in time after reaching the temperature, please move the blade gently (do not touch it directly with your hands. The maximum temperature the product can withstand is 350-400 degrees. Description: 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 fuels 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. Specification: 1.
