Chestnut, energy wood?
A wide variety of tree species can be used to produce firewood. If beech, oak or hornbeam are the best known in this category, there are others which can constitute an interesting alternative. The chestnut tree known for its fruit, the chestnut, is one of them. But is it good firewood?
Do all woods have the same combustible properties?
First of all, it should be noted that not all wood is created equal and each has its own characteristics when it comes to using it as firewood. Indeed, there are essences that are easier to ignite and others that burn more slowly.
In order to list the species, a classification has been established according to the humidity and hardness of the firewood. The letter H indicates humidity, while the letter G indicates hardness. For example, a hard hardwood tree that contains less than 20% humidity is classified H1G1.
Chestnut, a G2 category wood
Like birch, poplar, willow or linden, the chestnut is one of the soft hardwoods of class G2. This category has a lower calorific value than class G1 of hard hardwoods. On the other hand, the flames produced by this type of firewood are more visually pleasing. In addition, the purchase price is more affordable.
The chestnut tree burns quickly. In other words, it lights up easily and faster. This is why it is recommended for starting a fire.
But the negative point of the chestnut tree is the projection of coals when it burns. Indeed, when this gasoline burns, small flaming fragments are projected, which can prove dangerous if people are nearby. This could even be a source of fire if you are careless.
Under what conditions does the chestnut tree make good firewood?
Although chestnut is less “good” than hard hardwoods such as oak or beech, it is interesting in many conditions. As we mentioned above, it can be used very well to start a fire in your boiler, since it lights very easily and quickly.
In any case, it is more suitable for a closed fireplace, rather than an open one. This reduces the risk of flying debris and minimizes the risk of fire. It can also be used in a mass stove. This type of device retains the heat produced by a short-lived fire for quite a long time. So, even if the wood has been consumed, the heat continues to be diffused for at least a few hours.
Ultimately, is chestnut a good firewood?
In the end, even if chestnut is not as good as hard hardwoods, this wood represents a good alternative if you use a closed hearth and if you can regularly refuel your stove. Overall, one cubic meter of chestnut can provide 1 kWh and it is more affordable than class G700 in terms of purchase cost.
