Understanding Kiln-Dried vs. Unseasoned Firewood: A Comprehensive Guide for Home Firewood Users
Firewood is a popular choice for heating homes during the cold months. Two common types of firewood are kiln-dried and unseasoned firewood. This article will explore the differences between these two types, where to buy unseasoned firewood, and how to properly season it at home.

Kiln-Dried Firewood: A Higher-Performance Option
Kiln-dried firewood is a type of firewood that has been processed in a kiln to reduce its moisture content. This process makes the wood easier to burn and minimizes the production of creosote, a byproduct that can clog chimneys and damage heating systems. The process involves using a heated building with improved ventilation, which accelerates the drying process that, without additional heat and ventilation, could take up to a year.
Why Kiln-Drying is Costly, but Worth the Investment
While kiln-drying is a highly efficient method, it requires substantial heat and ventilation, thereby driving up the cost. If consumers were to kiln-dry firewood in their homes, the energy costs would likely negate the cost savings from using seasoned wood. It is important to note that kiln-drying is not reserved for firewood; it is commonly used for already cut lumber. Lumberyards and home centers may not offer kiln-dried firewood due to the high cost of the process.
Buying Unseasoned Firewood and Its Benefits
Unseasoned firewood, in contrast, has a higher moisture content and requires time to dry before it can be used effectively for burning in fireplaces or stoves. Unseasoned firewood can be purchased from lumberyards or home centers, though it is generally more affordable. Slabs, which are the bark-containing pieces cut off of logs to make them square, may also be available, though they can vary in their seasoning status.
When Unseasoned Firewood Comes from Lumberyards
Lumberyards may sell slabs for firewood, and these are often unseasoned depending on how long they have been left outside. Slabs are half-moon shaped and contain bark, making them less ideal for immediate use. Some lumberyards sell these slabs to a charcoal plant, indicating that they may not be suitable for home firewood.
Seasoning Unseasoned Firewood: A Step-by-Step Guide
If you wish to use unseasoned firewood, it is crucial to properly season it before use. The best way to season firewood at home is by stacking it in a well-ventilated area. It should be placed in an area with full sunlight, allowing the wood to dry over several months. The drying process can vary depending on the wood's density. Heavy and dense woods will require more time to dry, while lighter woods may dry faster. Some species of wood can dry in a year, while others may take 2 or 3 years.
Proper Stacking for Optimal Seasoning
To enhance the drying process, stack the firewood off the ground to allow for better air circulation. A well-ventilated area with full sunlight is ideal for firewood seasoning. Avoid stacking the wood against walls or in enclosed spaces, as this can trap moisture and hinder the drying process. Additionally, avoid stacking the wood in damp or rainy weather conditions. If you need to store the wood in a damp or rainy area, cover it with a breathable tarp to protect it from excessive moisture.
Alternative Options and Necessary Considerations
In some cases, a firewood cutter may be able to provide unseasoned firewood. At home, seasoning this type of firewood requires a similar approach to the one mentioned above. Some methods may include using a firewood rack, which allows for consistent airflow and reduces the risk of moisture buildup.
Sources of Unseasoned Firewood
Home centers often sell pre-seasoned firewood, which is not typically kiln-dried. Instead, it is air-dried, and the process is similar to that of home seasoning. Some large home centers may also sell rough-cut, unplanned lumber, which can be seasoned at home as well. When purchasing lumber from a lumberyard, ensure that it is seasoned and avoid purchasing raw-cut, unseasoned planks, as they may not be suitable for immediate firewood use.
Conclusion
Buying firewood can be an essential part of heating your home, and the choice between kiln-dried and unseasoned firewood depends on your specific needs and budget. Understanding the differences and proper seasoning techniques can help you make the best decision for your household.
