Black walnut trees are majestic and iconic, known for their rich, dark wood prized in woodworking and furniture making. But what about their value as firewood? The answer is a bit more nuanced than a simple yes or no. While black walnut can be used for firewood, it's not universally considered the best choice, and understanding its pros and cons is crucial. This guide delves into the specifics, answering common questions and providing a comprehensive overview.
What are the Burning Qualities of Black Walnut?
Black walnut wood possesses a high density and relatively slow burning rate. This translates to long, consistent burning, producing significant heat output over time. However, the high density also means it's denser than some other wood species, requiring more effort to split, especially when seasoned.
How Does Black Walnut Compare to Other Firewoods?
Compared to softer woods like pine or aspen, black walnut offers a much longer burn time and generates more heat. However, hardwoods like oak or maple often compete favorably in terms of heat output and ease of splitting. The real comparison depends on your priorities: consistent, long-burning heat versus ease of splitting and preparation.
Is Black Walnut Easy to Split?
No, black walnut is notoriously difficult to split. Its dense, strong grain makes it resistant to splitting, requiring significant effort and potentially specialized tools. This is a major drawback for many firewood users. Pre-splitting or using a hydraulic splitter is often recommended.
Does Black Walnut Produce Much Smoke?
Black walnut produces a moderate amount of smoke, less than some softer woods but more than some hardwoods. The smoke is generally considered pleasant by many, though some may find it slightly more acrid than other woods.
What is the BTU Rating of Black Walnut?
The BTU (British Thermal Unit) rating of black walnut is approximately 24 million BTUs per cord. This is a respectable rating, placing it among the higher-heat-output hardwoods.
Does Black Walnut Wood Have a Pleasant Smell When Burning?
Many find the scent of burning black walnut to be pleasant and slightly sweet, though opinions vary. It’s often described as having a subtle, nutty aroma.
Is Black Walnut Firewood Worth the Price?
The price of black walnut firewood varies depending on location and availability. Because of its difficulty to split and its value in other applications (lumber), it can often be more expensive than other hardwood options. Whether it's "worth it" depends on your priorities and budget. If consistent, long-lasting heat is paramount, and you have access to tools to handle splitting, it might be a good choice.
Conclusion
Black walnut makes excellent firewood, offering a long burn time and good heat output. However, its density makes it challenging to split. Consider your priorities, available tools, and budget before deciding if it's the right choice for your needs. Weigh the benefits of intense heat and a long burn against the added effort in preparation.
