Unless you live in Arizona or Texas with summer temps above 100 F and almost no humidity I would give it 2 years if not 3.
That's normal; it is almost impossible to buy truly seasoned wood. A few options:
- Try pallets: Most stores are happy to get rid off them and they burn well. It is a real chore to cut them up, however.
- Find some pine: Stacked and covered like above that may be just ok for burning this winter.
- Eco- or Biobricks (e. g. from Tractor Supply): More expensive than cord wood but not a lot more if you buy them in bulk.
- Find kiln-dried wood (or build yourself a solar-kiln): again, expensive option but possible
- Get some low moisture wood species like ash, dry it as well as you can and mix it with any of the options above.
- Trade: See if you can find someone (from here) who lives close by and has lots of seasoned wood. Offer to buy like 1.5 cords of green wood from your supplier for 1 cord of seasoned wood of your trading partner. Good would be a trade of 3 cords green wood for 2 cords seasoned wood.
To dry wood faster you can build a solar kiln (e. g. here:
http://www.builditsolar.com/Projects/WoodDrying/wood_kiln.htm ) or make small splits, stack them like you did with lots of sun and wind exposure. You can buy a moisture meter ($20 to $30) to test how far it is along. Take a few splits, re-split them and take a reading of the freshly exposed surface. Less than 20% is ideal but you can also get by with wood in the 20% to 25% range. Many people in their first year burn marginal wood and are very disappointed about their new stove. So you need to be aware that the stove will not burn as well, you will loose more heat up the chimney and you need to clean the chimney quite often. However, if you give that oak above another year you will really be happy with your purchase.
