1. Woodheat Fan: Quiet, Efficient, Carbon-Reducing Fireplace Upgrade

Introducing the Energy Saving and Environmentally Friendly 4-Blade Heat Powered Stove Fan. This innovative stove fan operates without the need for batteries, ropes, or electricity, making it a sustainable and cost-effective solution for your heating needs.
By harnessing the heat released by the surface of your stove, this fan generates its own energy. The base of the fan efficiently transmits this heat to the units of electricity production, which then convert the heat energy into kinetic energy. This energy powers the motor, causing the blades to rotate and dispense warm air throughout the room.
With its upgraded 4 blades, this stove fan ensures even distribution of warm air, creating a cozy and comfortable atmosphere. To get started, simply place the fan on a flat, smooth surface on the top of your stove, near the side or back of the stovepipe. It's important to position the fan at least 4 inches away from the stovepipe for optimal performance.
Once the base of the fan reaches a specified temperature range of 104°F to 150°F, the fan will automatically start rotating. The hotter the base becomes, the faster the fan will rotate, resulting in greater air circulation in your space. As the stove cools down, the fan will gradually slow down and eventually stop.
Crafted from high-quality anodized aluminum, this fireplace fan assembly is built to last. The anodized aluminum material not only prevents rust and corrosion, but it also ensures the fan's durability even during overheating situations. Additionally, a bimetallic safety device is installed at the base of the fan, providing protection for the Thermoelectric Generator (TEG) and motor. If the surface temperature exceeds 300°C, the safety device gently raises the front of the fan to prevent any damage.
One of the standout features of this stove fan is its quiet operation. With its unique blade design, the fan operates silently, allowing you to enjoy the warmth in a calm and peaceful environment. No more disruptive airflow or noisy fans.

Secondly, the fan operates without the need for any electricity or batteries, as it is entirely powered by the heat of the stove. This makes it an eco-friendly and cost-effective solution for enhancing the efficiency of wood burning stoves.
Lastly, the fan operates silently, as it does not rely on any moving parts or motors. This makes it a great addition to any living space, as it does not produce any noise while providing the benefits of improved heat distribution.
