Wood burning stoves are renowned for their efficiency and eco-friendliness, but the introduction of an extractor fan can enhance their performance. In this article, we’ll explore the technical details and advantages of using an extractor fan with your wood burning stove.
Understanding the Extractor Fan
An extractor fan, often referred to as a stove hood or stove fan, is a mechanical device installed above or near the wood burning stove. Its primary function is to improve the efficiency of the stove and create a more comfortable environment in your living space. Here’s how it works:
Air Circulation: The extractor fan uses a fan or blower to draw in the room’s air.
Passing Over the Stove: The drawn air passes over the hot surface of the wood burning stove, where it gets heated.
Exhaust Vent: The now heated air is expelled back into the room or directed outside, depending on the fan’s design.
Technical Details and Benefits
Improved Heat Distribution: The extractor fan helps distribute the heat generated by the stove more evenly throughout the room. This means you get a warmer and cozier environment.
Efficiency Boost: By spreading the warmth, the fan ensures that less heat is concentrated around the stove. This encourages more efficient combustion, as you won’t need to dampen down the stove to avoid overheating the immediate area.
Reduced Fuel Consumption: With improved combustion, you burn less wood to achieve the same level of warmth, resulting in cost savings and a reduced environmental footprint.
Enhanced Air Quality: Some extractor fans are equipped with filters to capture airborne particles. This helps maintain indoor air quality by reducing the release of particulates from the stove.
Minimized Cold Spots: Extractor fans can alleviate cold spots in large or open-plan spaces, ensuring that every corner of the room benefits from the stove’s heat.
Choice of Installation: Extractor fans can be installed to recirculate heated air back into the room or vent it outside. Your choice depends on your specific heating and ventilation needs.
Considerations When Choosing an Extractor Fan
Size and Capacity: Ensure that the fan you select is appropriately sized for your stove and room. Too small, and it won’t be effective; too large, and it can be noisy and overzealous in its operation.
Installation: Professional installation is recommended to ensure that the extractor fan is correctly positioned and vented according to safety and building codes.
Noise Level: Choose a fan with a noise level that suits your comfort preferences, especially if your wood stove is located in a living area.
Air Quality: If you’re concerned about air quality, consider an extractor fan with a filter to capture particulates and reduce their release into your home.
In Conclusion
An extractor fan is a valuable addition to your wood burning stove, offering technical benefits like improved heat distribution, enhanced combustion efficiency, and reduced fuel consumption. It also provides a comfortable and eco-friendly way to enjoy the warmth of a wood stove while maintaining indoor air quality. When selecting an extractor fan, consider factors like size, installation, noise level, and air quality to ensure it complements your wood burning stove setup.
