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, and
- The price you paid for that fuel.
The tool will calculate your Btu requirements based on your past use of fossil fuels and apply the Residential Demand Control Rate for your state to your heating energy and household electricity use.
Rate calculations include rates, adjustments, and riders effective May 2016.
