If coal can keep this house warm in those temps & lower, it'll keep anyone's house warm.musikfan6 wrote: .............
I can't wait to see what mine does when it's down in the teens and 20's. I'm told it will burn even better ..........
I ran the calculation that Saragnac did using my info ... and the strange thing is, with coal I used the exact amount of BTU's to heat the place ... except the temp in the house was 10° - 12° warmer. Guess the oil burner needs some work. It's a '96 and has a 85% efficiency rating too ... go figure.
