Firewood – The difference between seasoned and unseasoned firewood

Do you often hear people talking about seasoned and unseasoned wood and have not the faintest idea what the difference is?

What is seasoned wood?

Seasoned wood has been dried for about 1-2 years. It should have a moisture content of 20%. The moisture content of firewood determines how it burns and how much heat is released. Wood should be as dry as possible to ensure the cleanest burning.

The higher the moisture content, the more energy must be used to evaporate the water in the wood before it will burn. This means that less heat is produced and more condensation occurs in your chimney. This could lead to creosote build up and chimney fires.

You can clearly see the difference between seasoned and unseasoned wood

If you take a look at the photo above, you will see that the seasoned firewood is below( darker in colour and cracked). The unseasoned wood is lying on top, it still looks freshly cut and “green”.

What is unseasoned wood

Unseasoned wood is “green wood”. The moisture content varies by the species; green wood may weigh 70 to 100 percent more than seasoned wood due to water content.

What would can you use in a BioFire fireplace?

A BioFire Fireplace is a wood burning fireplace and requires the use of DRY WOOD. If you use wood with a high moisture content, your fireplace will not only smoke, bit it will fog up your fireplace door.

    I like the photo. You can definitely see the difference in the green wood compared to the seasoned wood. Splitting the firewood can help speed up the drying process because it will allow air to reach deeper into the wood, reducing the moisture. Also, a cover or shed can help keep the seasoned wood dry.
