Understanding Larch as Firewood
Larch: Hardwood or Softwood?
Larch is a softwood tree species that is commonly used for firewood. However, it is often mistaken for a hardwood due to its high density and durability.
Larch is a coniferous tree that belongs to the Pinaceae family, which includes other popular firewood species like pine, spruce, and fir. Despite being a softwood, larch has a high density, which makes it burn longer and hotter than many other softwoods.
FOUR Characteristics of Larch Wood
Larch wood has several characteristics that make it a good choice for burning in a wood stove. Here are some of the key features of larch wood:
- High density: Larch wood is denser than many other softwoods, which means it burns longer and hotter. The density of larch wood ranges from 590 to 690 kg/m³, making it one of the densest softwoods available.
- Low moisture content: Larch wood has a low moisture content, which means it burns more cleanly and efficiently. It also produces less smoke and creosote buildup in your chimney.
- Easy to split: Larch wood is relatively easy to split, which makes it a good choice for people who split their own firewood.
- Moderate sap content: Larch wood has a moderate sap content, which means it may produce some sap while burning. However, this can be minimized by seasoning the wood properly.
Here is a table that summarizes some of the key characteristics of larch wood:
| Characteristic | Description |
|---|---|
| Density | 590-690 kg/m³ |
| Moisture content | Low |
| Splitting difficulty | Moderate |
| Sap content | Moderate |

Larch’s Burning Properties
1. Heat Output of Larch
Larch wood is a softwood, but it has one of the highest heat productions compared to other softwoods, like pine.
When properly seasoned, larch can produce up to 20.3 million BTUs per cord. This means that larch can provide a lot of heat output, making it an excellent choice for burning in a wood stove.
2. Burning Characteristics of Larch
Larch wood is known for its slow and even burn. It produces long-lasting coals, which makes it an excellent choice for overnight burning.
Larch also produces minimal smoke and sparks, making it a safer option for indoor burning. However, it’s worth noting that larch does produce a lot of sap if unseasoned, which can cause issues with creosote buildup in your chimney.
Here’s a table summarizing the burning properties of larch wood:
| Property | Value |
|---|---|
| Heat output (when seasoned) | Up to 20.3 million BTUs per cord |
| Burn time | Slow and even |
| Coal production | Long-lasting |
| Smoke production | Minimal |
| Spark production | Minimal |
| Creosote buildup | Possible if unseasoned |
Preparation of Larch for Burning
If you are planning to burn larch wood in your wood stove, it is important to prepare it properly. This will ensure that your fire burns efficiently and safely. In this section, we will discuss how to season and split larch wood.
1. Seasoning Larch Wood
Seasoning is the process of drying wood to reduce its moisture content. Burning unseasoned wood can lead to poor combustion, excess smoke, and creosote buildup in your chimney. Larch wood should be seasoned for at least 6-12 months before burning.
To season larch wood, cut it into logs and stack it in a dry, well-ventilated area. It is important to keep the wood off the ground and covered with a tarp to protect it from rain and snow. You can also use a woodshed or covered porch to store your wood.
The ideal moisture content for seasoned wood is between 15-20%. You can use a moisture meter to test the moisture content of your wood. If the moisture content is above 20%, the wood needs more time to dry. If it is below 15%, the wood is over-dried and may burn too quickly.
2. Splitting Larch Wood
Splitting larch wood is an important step in preparing it for burning. Splitting the wood exposes more surface area to air and helps it dry faster. It also makes the wood easier to handle and stack.
To split larch wood, use a splitting maul or axe. Stand the log on end and strike it with the maul or axe, splitting it in half. Continue splitting the halves until you have manageable-sized pieces.
It is important to wear safety gear, such as gloves and eye protection, when splitting wood. Always stand to the side of the log, not in front of it, when striking it with the maul or axe.
TWO Potential Issues with Burning Larch
When it comes to burning larch in your wood stove, you should be aware of a few potential issues that may arise. In this section, we will discuss two of the most common problems associated with burning larch: smoke and creosote buildup, and sparks and pops.
1. Smoke and Creosote Buildup
One of the main issues with burning larch is the amount of smoke it produces. Larch has a high resin content, which means that it can produce a lot of smoke when burned. This can lead to a buildup of creosote in your chimney, which can be dangerous. Creosote is a highly flammable substance that can ignite and cause a chimney fire.
To prevent creosote buildup, it is important to ensure that your chimney is properly cleaned and inspected regularly. You should also avoid burning unseasoned larch, as this can produce even more smoke and increase the risk of creosote buildup.
2. Sparks and Pops
Another issue with burning larch is the potential for sparks and pops. Larch can produce a lot of sap when burned, which can cause sparks and pops to fly out of your stove. This can be dangerous, as these sparks and pops can start a fire in your home.
To reduce the risk of sparks and pops, it is important to ensure that your larch is properly seasoned before burning. This will reduce the amount of sap in the wood and make it less likely to produce sparks and pops. You can also use a spark arrester on your chimney to help prevent sparks and pops from escaping.
Comparison with Other Firewood Types
Larch vs. Other Softwoods
When it comes to softwoods, larch is a great option for burning in a wood stove. It has a high heat output and burns cleanly, producing minimal smoke and creosote buildup. However, there are other softwoods that can also be used for burning, such as pine, spruce, cedar, tamarack, alder, and poplar.
Compared to larch, pine, spruce, and balsam tend to burn faster and leave finer ash. They can also be messier to handle and cause creosote to build up more quickly in your chimney.
Cedar and tamarack are both good options for burning, but they have a lower heat output compared to larch. Alder and poplar are softer woods and burn quickly, making them better for kindling than for long-lasting fires.
Larch vs. Other Hardwoods
While larch is technically a softwood, it has many characteristics of a hardwood. When compared to other hardwoods, such as oak, maple, ash, beech, birch, cherry, and hickory, larch has a similar heat output and burn time.
However, hardwoods tend to be denser and heavier than softwoods, which means they take longer to dry and season properly.
Oak is known for its long, slow burns and is likely the best firewood overall. It is a dense hardwood that is available throughout most regions of North America.
Maple and ash are also good options for burning, with a high heat output and long burn time. Beech and birch are both dense hardwoods that burn hot and clean, but they can be difficult to split.
Cherry has a pleasant aroma and burns well, but it can be expensive. Hickory is a dense hardwood that burns hot and produces a sweet aroma, making it a popular choice for smoking meat.
Best Practices for Burning Larch in a Wood Stove
