Stacking firewood is an often underestimated but crucial aspect of wood stove operation. Properly stacked firewood not only ensures a steady supply of fuel but also promotes efficient burning and air circulation. In this guide, we’ll explore the technical details of stacking firewood in ways that are both functional and efficient.
1. Choosing the Right Location
Select a well-ventilated and dry location for your firewood stack. This area should protect the wood from rain, snow, and ground moisture. A woodshed or a covered area is ideal.
2. Stacking Techniques
There are several methods for stacking firewood, each with its own advantages:
a. The Cordwood Stack:
- Stack firewood in rows, parallel to each other.
- Allow some space between the logs to promote air circulation.
- This method is efficient and helps seasoned wood dry further.
b. The Holz Hausen Stack:
- This is a circular stack with a conical shape.
- The center is filled with smaller, irregular pieces of wood, while the outer layers consist of larger, split logs.
- This method maximizes airflow and minimizes the risk of moisture buildup.
c. The Crisscross or Crosshatch Stack:
- Stack wood by placing two logs parallel to each other.
- Add a layer of logs perpendicular to the previous layer.
- Repeat this pattern.
- This method creates stable and aesthetically pleasing stacks while still allowing air circulation.
3. Stack Height and Length
The ideal height for your firewood stack is around 4 to 5 feet. This height is convenient for both accessing the wood and allowing for proper air circulation. Additionally, the stack’s length should be in accordance with the wood stove’s firebox size. Typically, wood pieces should not exceed three-quarters of the stove’s firebox length.
4. Properly Seasoned Wood
Only stack well-seasoned wood. Well-seasoned wood has a moisture content of around 20% or less, which ensures efficient combustion and minimal creosote buildup. Avoid stacking green or freshly cut wood.
5. Maintain Your Stack
- Rotate your firewood stack regularly. Move older wood to the front of the stack for use, and place newer wood at the rear.
- Inspect your stack for any signs of insect infestations or rot. Remove any affected wood to prevent issues from spreading.
Conclusion
Properly stacked firewood is essential for efficient wood stove operation. Select the stacking method that best suits your needs, but always prioritize good air circulation and protection from the elements. By adhering to these technical details, you’ll ensure a reliable and efficient source of fuel for your wood stove, whether you’re an experienced user or new to wood-burning stoves.
