Heat Output Ranking (BTUs per Cord)
1. Oak (Red and White) - 24-27 million BTUs
2. Hickory: 25-28 million BTUs
3. Maple (Sugar and Red): 20-24 million BTUs
4. Ash: 20-23 million BTUs
5. Beech: 19-22 million BTUs
6. Birch (White and Yellow): 18-22 million BTUs
7. Cherry: 20 million BTUs
8. Walnut: 18-22 million BTUs
9. Poplar (Eastern): 14-18 million BTUs
10. Softwoods (e.g., Pine, Fir, Spruce): 15-20 million BTUs (softwoods vary widely, but generally lower than hardwoods)

Note:
Hardwoods typically produce more heat than softwoods due to teir higher density.
While softwoods like Pine can ignite quickly and produce a good initial heat, they generally burn faster and are less efficient for long-term heating compared to hardwoods.

Keep in mind that specific values can vary based on moisture content, tree age, and growth conditions. Properly seasoned wood will provide the best heat output. If you're considering wood for burning, its crucial to ensure its dry and well seasoned for optimal efficiency.

"You're telling me Red Oak burns the hottest?"
Yes, thats right! Red Oak (Quercus Rubra) is one of the higher-ranking hardwoods in terms of heat output when burned. While it might not reach the absolute peak of heat produced by Hickory, it still generates a significant amount of heat, making it a popular choice for firewood.
- Density: it holds more energy per volume compared to many other woods.
- Heat Output: typically falls in the range of 24-27 million BTUs per cord, making it one of the hotter burning woods.
- Long Burn Time: compared to softer woods, providing substantial heat.
