Wood Selection Criteria: The Foundation of Good Firewood

The quality of your firewood starts with the wood itself. Not all wood burns equally well. Here’s what I look for:

• Hardwoods vs. Softwoods: Hardwoods (oak, maple, ash, beech) are denser and burn hotter and longer than softwoods (pine, fir, spruce). For consistent heat output and extended burn times, hardwoods are generally preferred. However, softwoods can be useful for kindling or starting fires.
  • Data Point: Hardwoods typically have a density of 40-50 lbs/cubic foot when dry, while softwoods range from 20-30 lbs/cubic foot.
• Moisture Content: Freshly cut wood contains a high amount of moisture, which hinders combustion and produces excessive smoke. Firewood should be seasoned (dried) to a moisture content of 20% or less for optimal burning. I use a moisture meter religiously to ensure my firewood meets this standard.
  • Technical Requirement: Firewood must be dried to a moisture content of ≤20% to meet efficiency and emissions standards.
  • Practical Tip: Split firewood dries faster than unsplit logs. Stack the wood loosely in a sunny, well-ventilated area.
• Species-Specific Considerations: Different wood species have unique burning characteristics. For example, oak is known for its high heat output and long burn time, while ash splits easily and produces minimal smoke. Consider the specific needs of your customers and the availability of different wood species in your area.
• Log Dimensions: The size of the logs you process will depend on the size of your wood stove or furnace. Standard firewood lengths range from 12 to 24 inches. I typically cut my firewood to 16 inches, which fits most common wood stoves.
  • Measurement: Standard firewood length: 12-24 inches (30-60 cm).
  • Case Study: In a recent project, I processed a large quantity of oak logs for a local heating company. By consistently cutting the logs to 16 inches, I ensured they met the company’s specifications and maximized their efficiency.
