Outside forced air wood furnaces have become a popular choice for those looking to efficiently heat their homes using wood as a fuel source. In this article, we’ll provide a thorough review of these systems, focusing on their technical specifications, proper operation, and key considerations for those in search of reliable heating solutions.
Technical Specifications
When considering outside forced air wood furnaces, it’s crucial to understand their key technical specifications:
1. Heating Capacity
The heating capacity of these furnaces varies, allowing them to serve a range of residential and commercial applications. These units can effectively heat spaces from small cabins to large homes, workshops, and even barns. The heating capacity is often measured in British Thermal Units (BTUs), so it’s essential to choose a model that matches the square footage of your space.
2. Fuel Type
Outside forced air wood furnaces are specifically designed to burn firewood. It’s essential to use seasoned hardwoods such as oak, maple, or cherry for optimal performance. Dry, well-seasoned wood ensures clean combustion and reduces maintenance requirements.
3. Efficiency
Efficiency is a critical aspect of these furnaces. High-efficiency models can achieve ratings of 80% or more, which means they extract the maximum amount of heat from the wood, reducing fuel consumption and saving on heating costs. Advanced combustion technology and efficient heat exchangers contribute to this high efficiency.
4. Combustion Technology
Outside forced air wood furnaces employ advanced combustion technology to ensure clean and efficient burning of wood. This technology minimizes emissions, making them an environmentally responsible heating option. Many models use a secondary combustion process to burn wood gases and particles that would otherwise be released into the atmosphere.
5. Environmental Impact
It’s worth noting that many outside forced air wood furnaces are EPA-certified, meaning they meet strict emissions standards. This certification ensures they emit significantly fewer pollutants compared to older, less-efficient wood stoves, reducing their environmental impact.
Proper Operation
To ensure the effective and safe operation of an outside forced air wood furnace, follow these guidelines:
Proper Fuel: Use only dry, seasoned firewood to achieve optimal combustion. Avoid burning green or treated wood, which can release harmful chemicals and reduce efficiency.
Airflow Control: Adjust the air controls to regulate the combustion process and maintain a consistent burn. Proper airflow control is essential for maximizing efficiency.
Regular Maintenance: Clean the furnace and chimney at least once a year to prevent creosote buildup, which can be a fire hazard and decrease efficiency.
Professional Inspection: Schedule an annual inspection by a certified technician to ensure that your furnace is running safely and efficiently.
Considerations
When selecting an outside forced air wood furnace, consider factors such as your space’s size, the availability of wood in your area, and your specific heating needs. Verify that the unit complies with emissions standards and consider its overall environmental impact.
In summary, outside forced air wood furnaces offer an efficient and versatile heating solution for various applications. By carefully evaluating technical specifications, proper operation, and key considerations, you can make an informed decision when choosing a system that best suits your heating requirements.
