Free Outdoor Wood Burning Furnace Plans: A Comprehensive Guide

Wood burning furnaces provide an efficient and cost-effective way to heat your home during the cold winter months. If you're considering building your own outdoor wood burning furnace, there are several factors to consider and plans available to help you get started.

Materials and Planning

The first step is to gather the necessary materials, including a firebox, chimney, and blower. The size of the firebox will determine the output of the furnace, so determine your heating needs before choosing one. The chimney should be made of durable material and tall enough to provide proper draft.

Firebox Design

The firebox is the heart of the furnace and should be designed to maximize heat transfer. Consider using double walls with air circulation between them to improve efficiency. The firebox should also have a grate to allow for adequate airflow and ash removal.

Chimney Considerations

The chimney creates the draft necessary for combustion. Choose a chimney made of galvanized steel or stainless steel for durability. The height and diameter of the chimney should be proportionate to the size of the firebox. A taller chimney will provide better draft, but it may also require additional support.

Blower Selection

The blower is responsible for distributing the heated air throughout your home. Choose a blower that is rated for the size of your furnace and has a variable speed setting to adjust the airflow. The blower should also be equipped with a safety switch to prevent overheating.
