In the United States, approximately 75% of homes that use wood as a primary heating source are located in rural areas, highlighting the crucial role of accessible and efficient firewood. This article is designed to guide you through the ins and outs of using hemlock for firewood, blending my personal experiences with industry-backed knowledge to help you make informed decisions and optimize your wood processing techniques. Let’s get started!

Is Hemlock Good for Firewood? 5 Pro Tips for Faster Drying

Hemlock. The name itself might conjure images of shady forests and, perhaps, some skepticism about its suitability for the hearth. I’ve heard it all before: “Hemlock? That’s just kindling!” or “Burns too fast and dirty!” But over my years in the wood processing game, I’ve learned that almost any wood can be good firewood if you know how to handle it. Hemlock, with its unique characteristics, is no exception.

Understanding Hemlock: The Good, The Bad, and The Ugly

Let’s face it; hemlock isn’t winning any popularity contests in the firewood world. Compared to hardwoods like oak or maple, it’s lower in density and BTU (British Thermal Unit) output. But let’s not throw the baby out with the bathwater!

Here’s a quick rundown:

• Pros:
  • Easy to Split: Hemlock generally splits quite easily, which is a huge plus if you’re doing it by hand or with a less powerful splitter.
  • Dries Relatively Quickly: Compared to dense hardwoods, hemlock dries faster, making it a viable option if you need firewood in a shorter timeframe.
  • Readily Available: Depending on your region, hemlock can be abundant and relatively inexpensive.
• Cons:
  • Lower BTU Output: It doesn’t burn as hot or as long as hardwoods, meaning you’ll need more of it to heat your space.
  • More Smoke: Hemlock can produce more smoke than hardwoods, especially if it’s not properly seasoned.
  • Sparking: It can spark and throw embers, so it’s best used in a closed stove or fireplace.

My Hemlock Story: From Skeptic to Strategist

I remember the first time I was faced with a massive pile of hemlock logs. I was running a small-scale firewood operation, and a local logging company offered me a screaming deal on a load of hemlock. My initial thought was, “What am I going to do with this stuff?”

I knew my customers preferred hardwoods, and I was worried about selling a product that might disappoint them. But I’m not one to back down from a challenge. I decided to experiment and see if I could turn this “less desirable” wood into a usable product.

What I discovered was that with the right techniques, hemlock could be a valuable addition to my firewood offerings. I learned the importance of proper drying, strategic mixing with hardwoods, and honest communication with my customers about its properties.

Pro Tip #1: Master the Art of Proper Drying

This is where the rubber meets the road. Proper drying is absolutely crucial for hemlock, even more so than for hardwoods. The goal is to reduce the moisture content to below 20%. Here’s my tried-and-true method:

• Split It Early: Don’t let those logs sit around in the round. Splitting the wood as soon as possible after felling exposes more surface area, accelerating the drying process.
  • Data Point: Studies show that splitting wood immediately after cutting can reduce drying time by up to 50%.
• Stack It Right: This is where airflow is your best friend.
  • Elevate: Stack your wood on pallets or rails to keep it off the ground. This prevents moisture from wicking up into the wood.
  • Orientation: Orient your rows to take advantage of prevailing winds.
  • Spacing: Leave ample space between rows to allow for air circulation.
  • Actionable Tip: I use a modified version of the Swedish “holz hausen” method, creating a circular stack with a chimney effect in the center. This promotes excellent airflow and even drying.
• Location, Location, Location: Choose a sunny, well-ventilated location for your woodpile. Avoid shady, damp spots.
  • Personal Insight: I once made the mistake of stacking hemlock near a dense row of trees. The lack of sunlight and airflow resulted in a pile of moldy, unusable wood. Lesson learned!
• Cover It (Partially): Covering the top of your woodpile with a tarp or metal roofing can protect it from rain and snow. However, be sure to leave the sides open for ventilation.
  • Challenge & Solution: I’ve found that fully covering a woodpile can trap moisture and create a breeding ground for mold. A partial cover allows for airflow while still protecting the wood from the elements.

Pro Tip #2: Embrace the Power of the Moisture Meter

Guesswork has no place in firewood preparation. A moisture meter is an indispensable tool for determining when your hemlock is ready to burn.

• Invest in a Quality Meter: Don’t cheap out on this. A reliable moisture meter will give you accurate readings and prevent you from burning wet, smoky wood.
  • Recommendation: I prefer pin-type moisture meters, as they tend to be more accurate than pinless models.
• Take Multiple Readings: Don’t rely on a single reading. Take several readings from different pieces of wood in different parts of the pile.
• Aim for Below 20%: This is the magic number. Wood with a moisture content below 20% will burn efficiently and produce less smoke.
  • Data Point: The US EPA recommends a moisture content of 20% or less for optimal wood-burning efficiency and reduced emissions.
• Document Your Progress: Keep a log of your moisture readings over time. This will help you track the drying process and predict when your wood will be ready to burn.
  • Original Research: In my experience, hemlock typically takes 6-12 months to dry properly, depending on the climate and drying conditions.

Pro Tip #3: Strategic Mixing: The Hemlock Hybrid Approach

Hemlock on its own might not be the ideal firewood, but it can be a valuable component of a well-rounded firewood mix.

• The 70/30 Rule: I recommend mixing hemlock with hardwoods in a ratio of approximately 70% hardwood and 30% hemlock.
  • Rationale: The hardwoods provide the long-lasting heat, while the hemlock provides a quicker, hotter flame to get the fire going.
• Layering is Key: When loading your stove or fireplace, layer the hemlock on top of the hardwoods. This will help it ignite quickly and transfer the flame to the slower-burning hardwoods.
  • Personal Experience: I’ve found that this layering technique significantly improves the overall burning performance of a hemlock-hardwood mix.
• Consider the Application: For shoulder-season burning (spring and fall), when you don’t need as much heat, you might be able to use a higher percentage of hemlock.
  • Case Study: A local customer of mine uses a 50/50 mix of hemlock and birch for his shoulder-season fires. He finds that it provides just the right amount of heat without overheating his home.

Pro Tip #4: Tool Maintenance: Keeping Your Chainsaw Sharp and Ready

Working with any wood, including hemlock, requires sharp and well-maintained tools. A dull chainsaw is not only inefficient, but it’s also dangerous.

• Sharpen Regularly: I sharpen my chainsaw chain after every few tanks of gas, or more often if I’m cutting dirty or knotty wood.
  • Actionable Tip: Learn to sharpen your chain by hand with a file. It’s a valuable skill that will save you time and money.
• Maintain Proper Tension: A loose chain is a dangerous chain. Make sure your chain is properly tensioned according to the manufacturer’s instructions.
• Clean Your Saw: Regularly clean your chainsaw to remove sawdust and debris. This will help prevent overheating and extend the life of your saw.
  • Workflow Optimization: I keep a small brush and a can of compressed air in my truck for quick cleanings in the field.
• Check Your Bar: Inspect your chainsaw bar regularly for wear and damage. Replace it when necessary.
  • Data Point: A worn chainsaw bar can reduce cutting efficiency by up to 20%.

Pro Tip #5: Safety First: Protecting Yourself and Others

Wood processing is inherently dangerous. Always prioritize safety when working with chainsaws, axes, and other tools.

• Wear Proper Protective Gear: This includes a helmet, safety glasses, hearing protection, gloves, and chainsaw chaps.
  • Personal Story: I once witnessed a chainsaw kickback that sent a log flying towards a worker who wasn’t wearing a helmet. Fortunately, he was uninjured, but it was a close call.
• Be Aware of Your Surroundings: Watch out for overhead hazards, slippery footing, and other potential dangers.
• Use Safe Cutting Techniques: Learn and practice safe cutting techniques to minimize the risk of kickback and other accidents.
  • Recommendation: Take a chainsaw safety course from a qualified instructor.
• Never Work Alone: Always have someone nearby in case of an emergency.
  • Best Practice: I always carry a first-aid kit and a cell phone with me when I’m working in the woods.
• Stay Hydrated and Take Breaks: Wood processing is physically demanding work. Drink plenty of water and take frequent breaks to avoid fatigue.
  • Cost Savings: Preventing injuries translates to cost savings in the long run, from reduced medical expenses to increased productivity.

Overcoming the Hemlock Haters: Educating Your Customers

If you’re selling hemlock firewood, be upfront and honest with your customers about its properties. Don’t try to pass it off as oak or maple.

• Highlight the Benefits: Emphasize the ease of splitting, quick drying time, and lower price point.
• Explain the Mixing Strategy: Educate your customers on how to mix hemlock with hardwoods for optimal burning performance.
• Offer a Discount: Consider offering a discount on hemlock firewood to incentivize customers to try it.
• Provide Burning Instructions: Give your customers clear instructions on how to properly burn hemlock to minimize smoke and maximize heat output.
  • Original Research: I’ve found that customers who are well-informed about hemlock are more likely to be satisfied with their purchase.

Scaling Up: Hemlock in Commercial Operations

While hemlock might not be the primary choice for large-scale firewood operations, it can still play a role.

• Niche Markets: Target niche markets that are willing to accept hemlock, such as campers or outdoor enthusiasts.
• Blended Products: Offer a blended firewood product that includes hemlock along with other species.
• Industrial Applications: Hemlock can be used for industrial applications such as wood-fired boilers or cogeneration plants.
