What am I missing. 100 gallons of #2 heating oil produces 138,500,000 BTUs of heat.
Meanwhile, a cord of hardwood produces 32,000,000 BTUs of heat.
So, just to heat my house for 3 weeks is going to take 4 cords. Essentially, 4 cords of hardwood equals 100 gallons of heating oil. I must really be screwing something up here, or the websites giving me the BTU equivalents are screwing something up.
1 gallon of No 2 heating fuel has 138,000 btus, so 100 gallons would have 13,800,000 btus.
So, a cord of hardwood is about equal to 250 gallons of heating oil BTU wise. Am I correct about that? That, I can live with.
Here is a chart to compare cost, but I think a cord is closer to 130 gallons if I remember right?
