A wood stove is not an incinerator; contrary to popular belief, so we can not throw anything to get a nice outbreak. The question that arises then: what wood to use for a wood stove? And what are the pitfalls to avoid?
Which wood to use for a wood stove?
What are the best woods to use for a woodstove?
To make a fire, just put wood in a stove. But to make a good fire, we must pay attention to the wood that we will use in our stove. Here are the 3 golden rules to always respect:
- Hard wood Hardwoods are dense woods. That is to say that they will burn less quickly than so-called softwoods. The outbreak will last longer, and as dense woods produce a lot of embers, they will create more heat in the long run.
For a warm fire that lasts, we will choose for our stove: charm, oak, ash, maple, birch, elm, beech, willow, alder, linden, walnut.
Conversely, soft woods (basswood, walnut, alder, poplar, plane tree) and softwoods (spruce, fir, pine, cedar, cypress, larch) will have tendency to burn quickly and little heat.
- A dry wood. Whether you have a fireplace or a wood stove, the rule is the same: you never burn wet wood. A wet wood is a wood that will not burn well, will produce a lot of smelly smoke but few flames, will divide the performance of our stove by two, foul it quickly, and pollute more.
Note that a wood is considered dry when its residual moisture content does not exceed 20%. Generally, it takes 2 years to achieve this result; except for large logs, which naturally take longer to dry.
- A wood whose origin is known. Even if the solution "wood of recovery" (waste of furniture, construction...) seems more economic and more interesting, to use this type of wood for our stove is strongly disadvised.
Most of the time these woods have been treated, painted, varnished... On combustion, they will release toxic and polluting substances. And there is a good chance that they will foul and damage the stove duct.
Solutions that keep climbing: platelets and granules
The logs and the wooden sticks dense, that's good, but today there are more practical solutions in terms of wood to use for a wood stove. For example:
- Platelets. The concept of the wafer: shredded wood, in the form of chips. As the pads are used in stoves with automatic feeding, forgotten the chore of refueling of the stove! If platelets are one of the cheapest wood fuels (25 € the apparent cubic meter), they require a large volume to be stored.
- Wood pellets (or pellets). The pellets are small wooden tubes (2cm long) reconstituted from sawdust. They are of course more easily storable and transportable than logs or platelets.
Very economical, the price of these pellets varies depending on whether you buy them in bulk or in bags. Bulk ton is less expensive than bags.
