The reason we have decided to kiln dry our firewood is because all firewood needs to sit for at least 9-12 months at minimum before soaking wet on the inside causing your fire to actually go out. Firewood at minimum should be below 20% moisture before you attempt to burn it, that requires a good 12 months to even allow to to get near that moisture level. Most firewood companies and tree/landscaping companies around here split wood one month, and then will sell it to you the next month because they don't want to wait a year to sell it at a proper moisture level, which sucks for the customer!
It also does not help with Wisconsin's tough winters, you only have a couple months out of the year to allow yourself quality time for your wood to naturally air dry! This is horrible news for you the customer, and that is why we kiln dry our firewood and can do the seasoning process in 3-4 days! We get our moisture content down to below 15% which is impossible to achieve by air drying your firewood.
