Is Hemlock Good for Firewood? A Comprehensive Guide
Hemlock, a common evergreen tree in North America, is often a topic of discussion among firewood enthusiasts. The question, "Is hemlock good for firewood?" is surprisingly complex, with the answer depending on several factors. While it's not the best firewood choice, it's certainly usable, and understanding its properties is key to using it effectively.
What are the burning characteristics of hemlock?
Hemlock wood is relatively soft and has a lower density compared to hardwoods like oak or maple. This means it burns quickly and produces a hotter, faster flame. However, this also means it burns through faster, requiring more frequent replenishment. The heat output is moderate, making it suitable for quick burns rather than long, sustained ones. The scent produced while burning is often described as pleasant, somewhat resinous, but some find it slightly pungent.
Does hemlock produce much smoke?
Hemlock's smoke production is moderate. It's generally less smoky than softwoods like pine or fir, but more smoky than many hardwoods. The amount of smoke can also depend on how dry the wood is. Properly seasoned hemlock will produce significantly less smoke than green or damp wood.
How does hemlock compare to other firewood options?
When comparing hemlock to other firewood options, it falls somewhere in the middle. It's better than many softwoods in terms of heat output and smoke production but inferior to hardwoods in terms of burn time and overall heat energy. Hardwoods like oak, maple, and hickory provide longer burns and more sustained heat, making them ideal for extended use. However, hemlock is readily available in many areas and can be a viable option, especially for quick fires or supplementary burning.
Is hemlock difficult to split?
Hemlock is generally considered easy to split, particularly when seasoned. Its softer nature makes it less resistant to splitting than harder hardwoods. This ease of splitting makes it a good choice for those new to splitting firewood.
How important is seasoning hemlock firewood?
Seasoning is crucial for any firewood, but especially for hemlock. Properly seasoned hemlock will burn cleaner, produce less smoke, and provide a more efficient and enjoyable fire. Green or unseasoned hemlock can be difficult to ignite, produce excessive smoke, and create creosote buildup in your chimney. Aim for at least six months to a year of seasoning before burning.
What are the drawbacks of using hemlock for firewood?
The main drawbacks of hemlock firewood are its relatively short burn time and moderate heat output. Compared to hardwoods, it's less efficient in terms of energy produced per unit of wood. Additionally, if not properly seasoned, it can be smoky and prone to leaving creosote residue in your chimney.
Where can I find hemlock for firewood?
Hemlock is a common tree in many parts of North America. Depending on your region, you might find it on your property, in nearby forests (with necessary permits), or from firewood suppliers. Always ensure you have the legal right to harvest firewood before collecting it.
Is hemlock safe for indoor fireplaces?
Hemlock is generally safe for indoor fireplaces, provided it is properly seasoned and the chimney is regularly cleaned. However, its relatively quick burn and moderate heat output may not be ideal for long, sustained indoor fires.
In conclusion, while hemlock may not be the top choice for firewood compared to seasoned hardwoods, it's a usable and readily available option. Its ease of splitting and moderate burn characteristics make it suitable for certain situations. However, proper seasoning is paramount to ensure a clean, efficient, and safe burn.
