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 |
Table Notes
* The above calculations are based upon average operating furnace efficiencies that occur during a typical heating season.
Energy costs are based on data from the Fenelon Falls April, 22 2008.
** Efficiencies shown are for a WaterFurnace Envision 48,000 BTU model.
