FAQs

  • Why does firewood need to be split?

    Splitting firewood accelerates drying by exposing more surface area, enables proper ignition and combustion, and creates manageable sizes for efficient burning.

  • What firewood produces the best coals?

    Oak and hickory produce the best, longest-lasting coals. Black locust also excels where available, while ash provides good coals with easier processing.

  • What’s the best firewood for pizza ovens?

    Oak is best for pizza ovens, providing high heat and clean burning. Maple works well too, while fruitwoods like cherry add flavor when mixed with primary fuel.

  • How do you stack firewood correctly?

    Stack firewood in single rows on elevated supports, 4 feet high, with crisscrossed ends for stability. Cover only the top to allow airflow.

  • How much firewood do I need for winter?

    Most homes need 1-6 cords per winter depending on climate, home size, and whether wood is primary or supplemental heat.

Heat output varies dramatically between wood species, with the densest hardwoods producing significantly more BTUs (British Thermal Units) per cord than lighter softwoods. Choosing high-heat woods maximizes warmth and efficiency, particularly important if you rely on wood as a primary heat source.

Osage orange (also called hedge apple or bodark) tops the list as the hottest-burning firewood available in North America, producing an exceptional 32-33 million BTUs per cord. This extremely dense wood burns intensely hot and creates long-lasting coals. However, its extreme hardness makes splitting difficult, and regional availability is limited primarily to the central United States.

Hickory ranks among the most popular high-heat choices, delivering about 28-29 million BTUs per cord. It’s widely available across the eastern United States, splits more readily than osage orange, and produces excellent coals for overnight burns. Many consider hickory the best combination of heat output and practicality.

Black locust produces approximately 27-28 million BTUs per cord and shares hickory’s excellent burning characteristics. It seasons relatively quickly for a dense hardwood and resists rot exceptionally well during storage. In some regions, black locust is considered invasive, making it readily available and sometimes even free.

White oak and red oak both deliver strong heat output around 24-26 million BTUs per cord. Oak’s widespread availability, reasonable splitting difficulty, and excellent burning qualities make it the most commonly used premium firewood across much of North America.

While these hot-burning woods provide maximum heat, they also typically cost more, take longer to season, and require more effort to split. For most users, oak or hickory offers the best balance of heat output, availability, and workability. Save the extreme heat producers like osage orange for special situations where maximum BTUs matter most.
