    I'm not sure what the average was for the past year. Right now we're paying about $1.30/therm. We used about 1,000 therm for heating, plus another 100 or so with our gas insert in the basement.

    Once again, actual calculations based on real knowledge of a home are a lot more useful that opinionated conjecture.
