HOW MUCH HEAT ARE YOU GETTING FOR YOUR DOLLAR?

The energy used to heat your house is measured in BTUs (British Thermal Units). The size of your furnace is measured in heating BTUs it can provide; for example a common furnace size is 50,000 BTUs.
BTUs per $1.00 spent on Energy = (BTUs Used Conversion Factor) x (Furnace Efficiency)
(Current Cost of Energy)
Energy Used Conversion Factors
Electricity……1 Kilowatt Hour = 3,413 BTUs Propane…..……1 Litre = 25,217 BTUs
Oil………….…1 Litre = 36,668 BTUs Natural Gas……1 Cubic Meter = 35,314 BTUs
Table Notes
* The above calculations are based upon average operating furnace efficiencies that occur during a typical heating season.
