As someone who has spent many evenings gathered around a crackling fire, I’ve learned a thing or two about choosing the right firewood. Among the various options, ash wood often sparks interest and debate. Is it the ideal choice for your cozy hearth, backyard bonfire, or that camping trip you’ve been planning?

In this article, we’re going to explore the often-asked question: “Is Ash Good for Firewood?” Drawing from personal experience and thorough research, I’ll talk about the properties of this wood, compare it with other popular firewood choices, and weigh its pros and cons

The Characteristics of Ash


Ashwood is often celebrated for its robustness and resilience. It possesses a set of properties that significantly influence its efficiency and desirability as firewood. Unlike softer woods, ash is a hardwood, characterized by its denser and heavier nature.

This intrinsic density directly correlates to a slower burning rate and consequently, longer-lasting fires. An often-overlooked aspect of ash wood is its moisture content. When freshly cut, ash wood has a relatively lower moisture content compared to other hardwoods.

This attribute means that ash can be used for burning sooner after cutting, requiring less drying time. In terms of energy output, measured in British Thermal Units (BTUs), ash wood stands out with its high BTU rating, denoting a substantial heat release per unit of wood burned, a crucial factor for efficient heating.

Comparing Ash to Other Hardwoods

Seasoning and Storage

The way ash wood is seasoned and stored plays a pivotal role in its quality as firewood. Proper seasoning and storage not only ensure maximum heat output but also enhance the wood’s burning efficiency.

Ashwood’s seasoning time is relatively shorter than that of many hardwoods, thanks to its lower initial moisture content. This characteristic makes ash an appealing option for those who lack the time or space for long seasoning periods.

However, even with its lower susceptibility to moisture, proper storage is imperative. Storing ash wood in a dry, well-ventilated area helps prevent moisture absorption, thus preserving its burning quality and extending its useful life.

Benefits and Limitations of Using Ash as Firewood

1. Heating and Home Use

The high heat output and efficiency of ash make it an ideal choice for home heating. In wood stoves, ash burns hot and steadily, offering a consistent and dependable heat source. This attribute is particularly valuable in colder climates where maintaining a stable indoor temperature is crucial.

In open fireplaces, its minimal smoke production and good burning characteristics provide a more enjoyable and safer experience. For those looking to optimize their wood-burning practices, combining this wood with longer-burning woods like oak can be effective.

This combination balances the quick ignition and high heat output of ash with the extended burn time of denser woods, offering a practical and efficient heating solution.

2. Outdoor and Recreational Use

Beyond heating, ashwood is well-suited for outdoor and recreational settings. Its ease of lighting and moderate burn time make it a suitable choice for campfires, where both convenience and longevity are desired.

For outdoor cooking, such as grilling and smoking, this wood is preferable due to its high heat output and neutral flavor profile. This makes it ideal for cooking a variety of foods without the risk of altering their taste, a common issue with certain softwoods.

Additionally, the sturdiness of ash wood makes it a reliable choice for outdoor settings, where varying conditions can affect the performance of less robust woods.

Environmental and Sustainability Considerations


The use of ash as firewood is not just about its burning properties but also involves environmental and sustainability aspects. Choosing sustainably sourced wood is essential in minimizing environmental impact and supporting healthy forest ecosystems.

With the threat of pests like the emerald borer, responsible practices in the transportation and use of ash wood are crucial. These practices help mitigate the spread of such pests and preserve tree populations.

Furthermore, while ash is a commendable choice, exploring other eco-friendly firewood options can contribute to more sustainable and diverse wood-burning practices.


Can ash wood be burned green (unseasoned)?

While ash wood can technically be burned when green due to its lower moisture content compared to other hardwoods, it’s not recommended. Burning unseasoned wood can result in less efficient combustion, more smoke, and potential creosote buildup in chimneys.

For optimal results, it’s advisable to season the wood for at least 6 months.

How does Ashwood’s BTU rating compare to that of popular softwoods?

Ashwood typically has a higher BTU rating than popular softwoods like pine or cedar. This means it releases more heat energy per unit, making it more efficient for heating purposes. Softwoods, with their lower BTU ratings, burn faster and are better suited for kindling rather than as the main fuel source for heat.

Is ash safe to use for cooking and smoking food?

Yes, this wood is safe and often preferred for cooking and smoking food due to its neutral flavor profile. It does not impart any strong or undesirable flavors to the food, unlike some softwoods, which may release resinous flavors.

How does the emerald borer affect the quality of ash for firewood?

The emerald borer primarily affects the health and availability of ash trees rather than the quality of the wood for firewood. Infested trees can die and become dry, which might make them suitable for burning sooner, but the primary concern is the ecological impact and the decreasing population of these trees.

Can ash be mixed with other types of wood for burning?

Absolutely. Mixing it with other hardwoods like oak or beech can create a balanced fire with the benefits of both woods. Ash provides easy lighting and quick heat, while denser woods offer a longer burn time.
