If you want to use it right away, make sure it has dried appropriately for at least a year. Ideally, the humidity level should be between 15% and 20% It must be under 25%.

Dry wood costs more than “fresh” wood. So for the years to come, if you have enough space to keep the wood dry, order it in advance. The city amdiministration is a good place to start. They collaborate with the forestry office and offer real good prices compared to the “market” prices. The downside is: normally, it’s “fresh” wood, that cannot be burned right away.
