Burning Qualities of Ash Firewood
Ash firewood is known for its excellent burning qualities, making it a popular choice.
- Clean Burn: It produces a consistent flame and burns steadily, requiring less tending than some other wood varieties.
- Low Smoke: Ash wood produces relatively low smoke, a significant advantage for those seeking a cleaner, healthier fire, especially indoors.
- Pleasant Aroma: You'll enjoy a pleasant, subtle aroma while it burns, unlike some woods that can produce a strong or unpleasant smell.
- Easy to Start a Fire: Ash lights quickly and burns efficiently, providing a reliable source of heat.
- Easy Splitting: The straight grain of ash wood also contributes to its easy splitting, saving you time and effort.
Ash Firewood BTU Output: How Much Heat Does it Produce?
BTU, or British Thermal Unit, is a standard measurement of heat energy. When it comes to firewood, a higher BTU rating translates to more heat output per unit of wood. This is a critical factor to consider when selecting firewood, as it directly impacts how effectively your fire will warm your home.
Ash firewood has a BTU rating, averaging around 20 million BTUs per cord. This places it in the mid-range of hardwoods, offering a good balance of heat output and burn time.
While some hardwoods, like oak and hickory, have higher BTU ratings (around 28 and 26 million BTUs per cord, respectively), ash still provides substantial warmth.
Its lower BTU compared to oak or hickory doesn't necessarily mean it's inferior. A slightly lower BTU can sometimes translate to a longer burn time, meaning you won’t need to replenish your fire as frequently.
This balance of decent heat output and respectable burn time makes ash a practical and efficient choice.
Seasoning Ash Wood: Tips for Optimal Burning
Seasoning is the process of drying wood to reduce its moisture content. Burning green or unseasoned wood results in a less efficient fire, producing more smoke, creosote buildup in your chimney, and significantly less heat.
For ash wood, the recommended seasoning time is typically 6-12 months. This timeframe allows the wood to dry sufficiently, ideally reaching a moisture content below 20%.
How to Season Ash Wood
To properly season ash wood, follow these tips:
- Split the wood: Splitting wood increases the surface area exposed to air, accelerating the drying process.
- Stack the wood: Stack the split wood in a crisscross pattern to allow for good air circulation. Elevate the woodpile off the ground using pallets or logs to prevent moisture absorption from the soil.
- Cover the top: Cover the top of the woodpile with a tarp or waterproof covering to protect it from rain and snow. Ensure the sides remain open for adequate ventilation.
- Choose a sunny location: If possible, locate your woodpile in a sunny area to enhance drying.

How to Tell if Ash Wood is Seasoned
How can you tell if your ashwood is properly seasoned?
- Seasoned wood will be noticeably lighter than green wood.
- It will have a darker appearance and often have cracks or checks on the ends.
- You can test the moisture content using a moisture meter. A reading below 20% indicates properly seasoned wood.
Ash Firewood vs. Other Popular Choices
When deciding on the best firewood, it's helpful to compare different options. Here's how ash stacks up against other popular choices like oak, maple, and hickory:
| Feature | Ash | Oak | Maple | Hickory |
|---|---|---|---|---|
| BTU Output | Medium (20 million) | High (28 million) | Medium (24 million) | High (26 million) |
| Burn Time | Medium | Long | Medium | Long |
| Ease of Splitting | Easy | Medium | Medium | Difficult |
| Smoke Output | Low | Low | Low | Low |
| Aroma | Mild, pleasant | Mild | Sweet | Strong, distinctive |
| Cost | Moderate | Moderate to High | Moderate | High |
| Coaling Qualities | Good | Excellent | Good | Excellent |
- Ash: A good all-around choice with easy splitting and a clean burn. Excellent for fireplaces and wood stoves.
- Oak: A top performer in heat output and burn time, but can be more challenging to split. Best suited for wood stoves and fireplaces.
- Maple: Offers good heat output and a pleasant aroma, making it a popular choice for fireplaces.
- Hickory: Produces intense heat and a long burn, but it’s harder to split and has a strong aroma that some might find overpowering. Ideal for wood stoves and outdoor fireplaces.
Ash often presents a desirable balance between heat output, burn time, and ease of use, particularly for those who prioritize easy splitting. While it might not produce the same intense heat as oak or hickory, its clean burn, pleasant aroma, and moderate cost make it a compelling option.
- If you value ease of preparation and a consistently good fire, ash is an excellent choice.
- If maximum heat output is your priority, oak or hickory may be better suited to your needs.
