Dual Fuel Calculator
To use this calculator, first gather information about your present heating system and your energy costs. You'll need:
- The age or efficiency of your present heating system.
- The amount and type of fuel you've used over a one-year period.
- The price you paid for that fuel.
This tool will calculate your Btu requirements and apply the Small Dual Fuel Rate for your state.
Note: Our Dual Fuel calculator estimates that electricity will be used 90% of the time and the back-up system 10% of the time to provide heating during energy control.
Rate calculations include rates, adjustments, and riders effective May 2016.
