this years total oil consumption was 630 gallons. sounds like a lot but considering prior to 2005 we used on average 1300 gallons/year. in 2005 we put in a jotul f100 to help the heat. wish we could have gone bigger, but that is another story. between oil, canawick bricks, and cordwood we still spent almost $3200.00 to heat a 4,000 sq. ft. house that has a 1500 sq. ft. in-law (which takes most of the oil, separate zoning and no stove).that all together put about $1650.00 in our pockets. what I like is over 8 years 5000 gals. + not burned @ this year's price of 3.40, that's a cool $ 17,000.00. that buys a lot of bricks and splits. have a day folks
