If you’re searching for a reliable, long burning, and efficient firewood option, ash firewood might just be your answer. Known for its impressive heat output and easy splitting, ash has become a go-to choice for homeowners who rely on wood-burning stoves, fireplaces, or outdoor fire pits. But is it all good news?
In this guide, I’ll dive deep into the advantages, downsides, and burning truths about ash firewood so you can decide if it’s the right fit for your hearth.
Ash firewood is renowned for its high BTU output, low moisture content, and ease of splitting, making it an excellent choice for home heating. However, its availability can be limited due to environmental factors, and it burns relatively quickly compared to denser hardwoods like oak.
| Aspect | Details |
|---|---|
| Heat Output | Produces around 24 million BTUs per cord |
| Burn Quality | Burns steadily with minimal smoke and sparking |
| Seasoning Time | Can be burned green but best when properly seasoned |
| Splitting Ease | Easy to split due to its straight grain |
| Downsides | Susceptible to pests and the Emerald Ash Borer |
Key Takeaways
- Ash firewood is known for its high heat output and ease of splitting.
- It burns cleanly with minimal smoke and sparks, making it ideal for indoor and outdoor use.
- Ash can be burned green (freshly cut), but seasoned ash firewood performs better.
- Susceptible to pests and the Emerald Ash Borer.
- It’s widely available in many regions, but prices may vary depending on location.
- While ash firewood has many benefits, it’s not without its drawbacks, such as being less aromatic than other hardwoods.
What Makes Ash Firewood So Popular?
Ash firewood has earned a reputation as one of the top choices for burning, and for good reason. Let’s break down what makes it stand out:
1. High Heat Output
Ash is a dense hardwood, which means it produces a significant amount of heat when burned. On average, ash firewood has a BTU (British Thermal Unit) rating of 20-24 million BTUs per cord, making it comparable to oak and hickory.
This high heat output makes it an excellent choice for heating homes during colder months.
2. Low Moisture Content
One of the unique qualities of ash firewood is its low moisture content, even when freshly cut. While most firewood requires seasoning (drying) for 6-12 months before burning, ash can be burned green in a pinch.
However, seasoned ash firewood will burn more efficiently and produce less creosote buildup in your chimney.
3. Easy to Split
If you’ve ever struggled to split tough logs, you’ll appreciate how easy ash is to work with. Its straight grain and relatively low density make it a favorite for those who split their own firewood.
4. Clean Burning
Ash firewood produces minimal smoke and sparks, making it a safe and clean option for both indoor fireplaces and outdoor fire pits. This also means less maintenance for your chimney or stove.
The Downsides of Ash Firewood
While ash firewood has many advantages, it’s not perfect. Here are some potential drawbacks to consider:
1. Less Aromatic Than Other Woods
If you love the smell of burning wood, ash might not be your top choice. Unlike cedar or pine, ash doesn’t have a strong, pleasant aroma.
It’s more neutral, which can be a pro or con depending on your preferences.
2. Availability and Cost
Ash trees have been heavily affected by the emerald ash borer, an invasive beetle that has decimated ash populations in many areas. This has led to reduced availability and higher prices in some regions.
3. Shorter Burn Time Compared to Oak
While ash burns hot, it doesn’t last as long as denser hardwoods like oak or hickory. You may need to replenish your fire more frequently when using ash firewood.
How Does Ash Firewood Compare to Other Types?
| Firewood Type | Heat Output (BTUs) | Ease of Splitting | Smoke Level | Aroma | Burn Time |
|---|---|---|---|---|---|
| Ash | 20-24 million | Easy | Low | Neutral | Medium |
| Oak | 24-28 million | Moderate | Low | Mild | Long |
| Pine | 14-18 million | Easy | High | Strong | Short |
| Maple | 18-24 million | Moderate | Low | Mild | Medium |
| Hickory | 24-28 million | Difficult | Low | Strong | Long |
How Efficient Is Ash Firewood?
| Wood Type | Energy Efficiency (%) | Burn Duration (Hours) |
| Ash | 85% | 4-6 hours |
| Oak | 90% | 5-7 hours |
| Maple | 80% | 3-5 hours |
| Pine | 65% | 2-4 hours |
How to Properly Season and Store Ash Firewood
Even though ash can be burned green, seasoning it will improve its performance. Here’s how to do it right:
- Split the Wood: Splitting ash logs into smaller pieces will help them dry faster.
- Stack Properly: Use a firewood rack or pallets to keep the wood off the ground and allow air to circulate.
- Cover the Top: Use a tarp or firewood cover to protect the wood from rain and snow, but leave the sides open for airflow.
- Wait 6-12 Months: While ash can be burned sooner, waiting at least 6 months will ensure optimal burning conditions.
FAQs
Is ash firewood safe for indoor fireplaces?
Yes, ash firewood burns cleanly with minimal smoke and sparking, making it ideal for indoor use.
Can I burn ash firewood without seasoning?
You can, but seasoning for at least 6 months improves heat output and efficiency.
How long should ash firewood season?
Ideally, let ash season for 6–12 months, although it can burn reasonably well when green.
Is ash firewood better than oak?
While oak burns longer and produces slightly more heat, ash is easier to split and burns more cleanly when green.
Can pests infest ash firewood?
Yes, especially the Emerald Ash Borer. Always source wood locally and inspect for pests.
