Logs are typically placed on end, rather than flat, when stacked as cord wood for burning in a fireplace or stove for several reasons:
Improved Air Circulation: Stacking logs on end creates gaps or spaces between them, allowing air to circulate more freely through the stack. Sufficient airflow is essential for efficient combustion. When logs are stacked flat, they can pack together more tightly, reducing airflow and potentially making it more difficult to start and maintain a fire.
Faster Drying: Placing logs on end exposes more of their surface area to the air, which helps the wood dry out more quickly. Drier wood burns more efficiently and produces less smoke and creosote buildup in the chimney.
Easier Lighting: When logs are stacked on end, it is easier to ignite the fire and get it going. The gaps between the logs allow flames to travel upward and ignite the wood more effectively.
Stability: Stacking logs on end creates a stable structure that is less likely to collapse compared to a flat stack. This is especially important if you are stacking wood outdoors, where weather and wind could affect the stability of the stack.
Space Efficiency: Stacking wood on end can be more space-efficient because it allows you to fit more wood in a smaller area, making it easier to store a larger supply of firewood.
Aesthetics: Some people prefer the visual appearance of a wood stack with logs placed on end. It can look neat and organized, especially if the logs are of similar size and shape.
It's important to note that while stacking logs on end has its advantages, the key to a successful fire is using properly seasoned wood. Seasoned firewood has lower moisture content, which leads to better burning efficiency and less creosote buildup in the chimney. No matter how the wood is stacked, using well-seasoned firewood is crucial for safe and effective wood burning.
