Just had my wood stove installed last fall....perfect timing it seems. I filled my 275 gallon oil tank in October. I have used roughly half the tank so far and about 3 cords of wood. I have supplemented heat in my upstairs with a space heater before bed, especially on the cold days when the sun doesn't really heat up the house. The only electricity that I use is what I have banked from my solar production. I have not had an electric bill since my September bill. I paid $200 per cord, 4 cords total at the beginning of the season, paid $2.42 per gallon for the oil, early in the season....
