When it comes to choosing firewood for your wood-burning stove, not all wood types are created equal. One wood species that often sparks curiosity is red elm. In this article, we’ll explore the suitability of red elm as firewood, considering its technical details and practical aspects.
Technical Details
Density and Hardness: Red elm (Ulmus rubra) is a hardwood with moderate density and hardness. It falls between softwoods like pine and hardwoods like oak on the density scale.
Moisture Content: The moisture content of firewood is a crucial factor. Red elm, like all firewood, should be seasoned to achieve a moisture content of 20% or less for efficient burning. Green or unseasoned wood will produce less heat and more creosote.
BTU Value: Red elm has a respectable energy value, with approximately 20-22 million BTUs per cord. While this is lower than some hardwoods like oak, it still provides a decent amount of heat.
Is Red Elm Good Firewood?
Pros:
Easy to Split: Red elm typically splits easily, making it suitable for those who don’t want to struggle with tough, knotty wood.
Decent Heat Output: Red elm offers a reasonable amount of heat, especially when well-seasoned.
Minimal Sparking: Compared to some other firewood types, red elm tends to produce fewer sparks, enhancing safety.
Cons:
Moderate Density: While it’s a hardwood, red elm is not as dense as some other hardwoods like oak or hickory. This means it may not burn as long or as hot.
Moisture Sensitivity: Like all firewood, red elm must be properly seasoned. It’s sensitive to moisture, and burning wet wood can lead to inefficiency and creosote buildup.
Availability: The availability of red elm can vary by region, so it may not be as accessible as some other wood types.
Proper Utilization
If you choose to burn red elm in your wood-burning stove, follow these guidelines:
Seasoning: Ensure your red elm firewood is well-seasoned with a moisture content of 20% or less. This can take at least 6-12 months or longer, depending on storage conditions.
Storage: Store your firewood in a dry, well-ventilated area to prevent moisture absorption.
Mix with Other Woods: To optimize your wood stove’s performance, consider mixing red elm with other hardwoods like oak or hickory. This can provide a longer and hotter burn.
Conclusion
Red elm can be good firewood for your wood-burning stove, provided it’s properly seasoned and used in combination with other hardwoods. Its ease of splitting and moderate heat output make it a reasonable choice, particularly if you have access to this wood type. As with any firewood, the key to successful burning is proper preparation and maintenance.
