The energy used to heat your house is measured in BTU’s (British Thermal Units).
The size of your furnace is measured in heating BTU’s it can provide; for example a common furnace size is 50,000 BTU’s. BTU’s per $1.00 Spent = (BTU’s per Energy Used Conversion Factor) x (Furnace Efficiency) (Current Cost of Energy) Energy Used Conversion Factors Electricity……1 Kilowatt Hour = 3,413 BTU’s Propane…..……1 Litre = 25,217 BTU’s Oil……………1 Litre = 36,668 BTU’s Natural Gas……1 Cubic Meter = 35,314 BTU’s |
