100% wood heat. Well, 99%. We do use electric space heaters selectively in the basement, which is seldom occupied and which is poorly heated by the stove. We have an electric heat pump and nothing else, so it runs full-on in Aux Heat mode in the cold months. The one month we did this (not realizing, because we had never had a heat pump before), the electric bill was something like $400. I've made sure that we have never run out of firewood since. Come spring, when everyone is having trees taken out, or after a bad storm, I troll Craigslist like a madman scrounging free wood, then I spend all summer splitting and stacking it. There's also a local tree service that keeps a list of homeowners, and if they take out a tree near your house, they'll call and drop it off if you want. I got from him a couple of trunk sections that were probably 4.5' to 5' in diameter, no lie, and 6' to 8' long. I had to pay somebody else from a tree service to come over and buck them with his big saw, then I split them myself, but I still came out way ahead on the proposition. The wood was so hard that it totally stalled my neighbor's 30-ton splitter. Instead, I had to go at it with sledge and wedges. It was impossible to split down the middle, so I used the wedges to peel 6"-12" wide strips off the outside first until it was down to maybe 3' in diameter, then split it down the middle. It was a ridiculous amount of labor, but I really loved it, and it was an incredible sense of accomplishment when it was done.
