I do cut from the property the dead wood, but it is not enough, about two cords each season. I get a 10 cord load of firewood delivered on a huge logging truck in lengths that I cut up and split myself every two years. It costs $2,000. Cheap for two years of heating. I would go through $2000 worth of oil in one month in winter despite the fact that this house has above average insulation. The foam board insulation added to the walls, and the new doors over ten years ago has paid off in terms of savings and comfort. It is -24C outside and inside it is 25C as I type which is almost a 50C degree difference between outside and indoor temperatures, I wouldn't want to be heating with oil at this temperature range.Do you ever buy wood, or do you cut them in season and store all of them?
