Is Ash Good Firewood? (5 Proven Tips for Perfect Seasoning)

The Great Firewood Gamble: Is Ash Worth the Effort?

Let’s be honest, we’ve all been there. Staring at a pile of freshly felled logs, wondering if the sweat and toil of transforming them into crackling warmth will actually pay off. The firewood game is a gamble, a test of patience, and a constant learning curve. I remember one particularly brutal winter where I swore the oak I’d meticulously seasoned was conspiring against me, refusing to burn with anything more than a sullen smolder. That’s when I truly started to appreciate the nuances of different wood species.

So, you’re eyeing up a pile of ash, huh? Good choice. Ash is often touted as one of the kings of firewood, but like any monarch, it has its quirks and demands. Is it really that good? And more importantly, how do you ensure you’re getting the most out of it? Let’s dive deep into the world of ash firewood, separating fact from fiction and equipping you with the knowledge to make your own judgment.

Is Ash Good Firewood? The Short Answer: Absolutely!

Ash consistently ranks high in the firewood hierarchy. It offers a solid BTU (British Thermal Unit) output, meaning it packs a good punch of heat. It’s relatively easy to split, and perhaps most importantly, it seasons reasonably quickly.

But here’s the thing: “good” is subjective. What works for me in my wood stove might not be ideal for your open fireplace. Let’s look at why ash is generally considered a top-tier firewood choice:

• High Heat Output: Ash boasts a BTU rating of around 20 million per cord. This puts it in the same league as oak and birch, meaning you’ll get a lot of heat for your effort.
• Easy to Split: Compared to some of its more stubborn counterparts (I’m looking at you, elm!), ash splits relatively easily, especially when green. This can save you a lot of time and energy.
• Seasons Relatively Quickly: Ash can be ready to burn in as little as 6-12 months, depending on your climate and seasoning methods. This is a significant advantage over oak, which can take two years or more to properly season.
• Low Smoke: When properly seasoned, ash burns with relatively little smoke, making it a cleaner and more enjoyable fuel.
• Burns Well Green (Sort Of): While always best to burn seasoned firewood, ash is one of the few species that can be burned green in a pinch, although it will produce less heat and more smoke. I wouldn’t recommend relying on this, but it’s a useful characteristic to know.

The Emerald Ash Borer: A Sobering Reality

Before we get too carried away praising ash, we need to address a significant threat: the Emerald Ash Borer (EAB). This invasive beetle has decimated ash populations across North America and continues to spread. The EAB larvae bore into the wood, disrupting the tree’s ability to transport water and nutrients, eventually killing it.

The unfortunate reality is that many ash trees are already dead or dying due to EAB. This can make ash readily available as firewood, but it also presents some challenges. Trees killed by EAB can become brittle and more difficult to split. It’s crucial to inspect ash trees carefully before felling them to ensure they’re safe to work with.

My Personal Ash Experience: A Tale of Two Stoves

I’ve burned a lot of ash over the years, and my experience has been overwhelmingly positive. I primarily use it in two different stoves: a large airtight wood stove in my workshop and a smaller stove in my cabin.

In the workshop, the ash provides consistent, long-lasting heat, allowing me to work comfortably even on the coldest days. I find that a single load of ash can burn for 6-8 hours, providing a steady source of warmth.

In the cabin, the smaller stove requires a more delicate touch. Ash burns hot and fast, so I need to be careful not to overload the stove. However, it’s perfect for quickly warming up the cabin on a chilly evening.

5 Proven Tips for Perfect Ash Firewood Seasoning

Okay, so you’re convinced that ash is worth the effort. Now, let’s get down to the nitty-gritty of seasoning. Proper seasoning is essential for getting the most out of your firewood, regardless of the species. Seasoning reduces the moisture content of the wood, making it easier to ignite, burn hotter, and produce less smoke.

Here are five proven tips for perfectly seasoning ash firewood:

1. Split It First, Then Stack It Right

This is non-negotiable. Splitting the wood before seasoning dramatically increases the surface area exposed to the air, accelerating the drying process. Think of it like this: a whole log is like a tightly sealed package, while split pieces are like opening that package and letting the air circulate.

• Why It Works: Splitting reduces the size of the wood, allowing moisture to escape more easily.
• My Experience: I’ve experimented with seasoning both whole logs and split pieces, and the difference is night and day. Split wood seasons at least twice as fast.
• Data Point: Studies have shown that split firewood can lose up to 50% of its moisture content in the first six months of seasoning, compared to only 10-20% for whole logs.

Once split, it’s crucial to stack the wood properly. Don’t just throw it in a heap! A well-stacked pile allows for maximum airflow, which is key to efficient seasoning.

• The Ideal Stack:
  • Off the Ground: Use pallets, scrap lumber, or even a layer of rocks to elevate the wood off the ground. This prevents moisture from wicking up from the earth.
  • Single Rows: Stack the wood in single rows, allowing air to circulate on all sides.
  • Space Between Rows: Leave a few inches of space between each row to further improve airflow.
  • Cover the Top: Cover the top of the stack with a tarp, metal roofing, or even a layer of scrap wood to protect it from rain and snow. However, do not cover the sides, as this will trap moisture.
• My Experience: I’ve found that using pallets to elevate the wood is particularly effective. They provide excellent airflow and prevent the wood from rotting from the bottom up.
• Data Point: Wood stacked directly on the ground can take up to twice as long to season as wood stacked off the ground.

2. Location, Location, Location: Choose Your Seasoning Spot Wisely

The location of your woodpile is just as important as how you stack it. You want to choose a spot that is sunny, windy, and well-drained.

• Sunlight: Sunlight helps to evaporate moisture from the wood. Choose a spot that gets plenty of direct sunlight throughout the day.
• Wind: Wind helps to carry away moisture-laden air, further accelerating the drying process. Choose a spot that is exposed to prevailing winds.
• Drainage: Avoid areas that are prone to flooding or standing water. Excess moisture will hinder the seasoning process.
• My Experience: I have two woodpiles: one in a sunny, windy spot and another in a more shaded area. The wood in the sunny spot always seasons much faster.
• Data Point: Wood seasoned in a sunny, windy location can dry up to 50% faster than wood seasoned in a shaded, sheltered location.

3. The Moisture Meter: Your Secret Weapon

A moisture meter is an invaluable tool for determining when your firewood is properly seasoned. These devices measure the moisture content of the wood, giving you a precise reading of its dryness.

• How to Use a Moisture Meter: Simply insert the probes of the meter into a freshly split piece of wood. The meter will display the moisture content as a percentage.
• Target Moisture Content: For optimal burning, firewood should have a moisture content of 20% or less.
• My Experience: I rely heavily on my moisture meter to ensure that my firewood is properly seasoned. It takes the guesswork out of the process and helps me avoid burning wet wood.
• Data Point: Burning firewood with a moisture content above 20% can reduce its heat output by up to 50% and significantly increase smoke production.

4. The End-Grain Test: A Low-Tech Alternative

If you don’t have a moisture meter, you can still get a good idea of the wood’s dryness by examining the end grain.

• Look for Cracks: As wood dries, it shrinks and cracks. Look for cracks radiating outward from the center of the end grain. The more cracks, the drier the wood.
• Feel the Weight: Seasoned wood will feel significantly lighter than green wood.
• Listen to the Sound: When you knock two seasoned pieces of wood together, they should produce a hollow, resonant sound. Green wood will sound dull and thudding.
• My Experience: I often use the end-grain test as a quick and easy way to assess the dryness of firewood. It’s not as precise as a moisture meter, but it can give you a good general idea.
• Caveat: This method takes practice and experience. You’ll need to handle a lot of wood to develop a feel for the differences between seasoned and green wood.

5. Be Patient: Time is Your Ally

Seasoning firewood takes time. There’s no way to rush the process. While ash seasons relatively quickly compared to some other species, it still needs at least 6-12 months to dry properly.

Rushing the process will only result in wet, smoky fires.

Beyond Seasoning: Optimizing Ash Firewood Performance

Once your ash is properly seasoned, there are a few other things you can do to optimize its performance in your fireplace or wood stove:

• Proper Storage: Store seasoned firewood in a dry, well-ventilated area to prevent it from reabsorbing moisture.
• Kindling is Key: Use plenty of dry kindling to get your fire started quickly and efficiently.
• Airflow Control: Adjust the airflow in your fireplace or wood stove to control the rate of combustion. More airflow will result in a hotter, faster-burning fire.
• Regular Maintenance: Clean your chimney regularly to prevent creosote buildup, which can be a fire hazard.

Ash vs. Other Firewood Species: A Comparative Analysis

Let’s see how ash stacks up against some other popular firewood species:

As you can see, ash offers a good balance of heat output, seasoning time, and splitting ease. It’s a versatile firewood species that can be used in a variety of applications.

Cost-Effectiveness of Ash Firewood

The cost of ash firewood can vary depending on your location and the availability of the wood. In areas where EAB has decimated ash populations, the price may be lower due to the abundance of dead or dying trees.

However, it’s important to consider the long-term cost-effectiveness of ash firewood. While it may be cheaper than some other species, its high heat output and relatively quick seasoning time can make it a more economical choice in the long run.

Safety Considerations When Working with Ash

Working with firewood can be dangerous if proper safety precautions are not taken. Here are some important safety considerations to keep in mind when working with ash:

• Wear Protective Gear: Always wear safety glasses, gloves, and sturdy boots when felling, splitting, and stacking firewood.
• Use Proper Tools: Use sharp, well-maintained tools. A dull axe or chainsaw is more likely to cause an accident.
• Be Aware of Your Surroundings: Be aware of your surroundings and avoid working in areas with overhead hazards, such as falling branches.
• Get Help When Needed: Don’t be afraid to ask for help when felling large trees or moving heavy logs.
• Chainsaw Safety: If using a chainsaw, follow all manufacturer’s instructions and wear appropriate chainsaw safety gear, including a helmet, ear protection, and chaps.

Ash Firewood: A Sustainable Choice?

The sustainability of using ash firewood is a complex issue. On one hand, the abundance of dead and dying ash trees due to EAB makes it a readily available resource. On the other hand, harvesting ash can contribute to the decline of ash populations and disrupt forest ecosystems.

To make the most sustainable choice, consider these factors:

• Source Locally: Purchase firewood from local sources to reduce transportation costs and support local economies.
• Harvest Responsibly: If you’re felling your own ash trees, choose trees that are already dead or dying.
• Consider Alternatives: Explore alternative heating options, such as solar or geothermal, to reduce your reliance on firewood.
