Please note: Our Fuel Efficiency Comparison Calculator is intended for relative comparisons, your actual usage may vary significantly from "average". An "average" house is considered to be 2000sq.ft., slab on grade, standard stick-frame construction, with R-30 ceilings and R-19 walls in an area with 30 degrees seasonal average low temperatures. To the extent your actual heating requirements are more or less than those assumed, relative differences between fuel type and heater efficiency will be greater or lesser
