Comparison of different types of kiln dried firewood: oak, hornbeam, birch, red oak
Share
When it comes to heating your home with kiln dried firewood, not all wood types are created equal. Kiln dried wood has a significantly lower moisture content, usually under 18%, which results in greater energy efficiency. In this article, we compare four popular types of kiln dried firewood: oak, hornbeam, birch and red oak. We look at their energy values both in kWh/kg. Let's take a closer look at the details!
Oak
Energy value (oven dried):
- kWh/kg: Approximately 4.2 to 4.8 kWh/kg
Oak is one of the most popular types of firewood, known for its high energy content and long burning time. It is a dense hardwood that burns slowly and provides consistent heat. Kiln dried oak has a low moisture content, which means it burns efficiently and with minimal smoke. Ideal for long winter nights when a consistent, long-lasting heat source is needed.
Hornbeam
Energy value (oven dried):
- kWh/kg: Approximately 4.3 to 5.0 kWh/kg
Hornbeam, often less well known compared to other firewood species, offers excellent energy value. Its density is even higher than that of oak, which means it burns longer and hotter. Kiln-dried hornbeam is particularly efficient and produces a high heat output, making it an excellent choice for those who want to maximize the heat output of their firewood.
birch
Energy value (oven dried):
- kWh/kg: Approximately 4.1 to 4.7 kWh/kg
Birch is a softer hardwood compared to oak and hornbeam, but still offers good energy value. It burns quickly and is easy to light, making it a great option for kindling. Kiln dried birch burns cleanly and with a pleasant scent that is often perceived as pleasant, making it a practical choice for those who need wood ready to burn more quickly.
Red oak
Energy value (oven dried):
- kWh/kg: Approximately 4.0 to 4.6 kWh/kg
Red oak, similar to its relative white oak, is a popular choice for firewood due to its availability and good energy value. It burns slower than birch, but faster than hornbeam and white oak. Kiln-dried red oak offers a good balance between burn time and heat output, making it a versatile choice for various heating needs.
Conclusion
When choosing kiln dried firewood, it is important to consider both the energy value and the specific needs of your heating system. Here is a quick summary of the energy values of each type:
- Oak: Approximately 4.2 to 4.8 kWh/kg
- Hornbeam: Approximately 4.3 to 5.0 kWh/kg
- Birch: Approximately 4.1 to 4.7 kWh/kg
- Red oak: Approximately 4.0 to 4.6 kWh/kg
For those looking for the highest energy output and longest burn time, hornbeam is the best choice. If you prefer a balance between availability, burn time and heat output, red oak and oak are excellent options. For faster lighting and a pleasant scent , birch is ideal.
Remember that kiln-dried firewood burns particularly efficiently due to its low moisture content. Choose the type that best suits your heating needs and enjoy the warmth and comfort of a well-heated home.
