Just came across this thread
I've been heating my shop with wood for 10 years and our house for 3. I have a small tree care business and over the years I've discovered that the type of wood you have makes a big difference in the drying time. Most woods, if split and stacked in spring or early summer, will be ready for the coming winter. Mulberry is very wet and takes longer.
Ash has a very low moisture content and will burn well in an existing fire even fresh cut although you probably won't be able to start a fire with it. Maple and walnut dry rather quickly. Oak, locust, and fruit wood will take longer. In general the more dense the wood the longer it takes to dry but it produces far more heat.
I use the lighter density wood in early and late winter and the heavier wood in the coldest part of the season. 
I pulled the oil furnace out of the basement when it died, put the wood furnace in, tied in the existing duct work, and used the same chimney. Make sure it is clean!  During a power outage I crack open a window in each of the upstairs rooms and let convection do the rest. We burn about 8 cord a season
We are always toasty warm now in our 100 year old farm house that has very little insulation and I love watching the oil truck pass us by.
