natural gas
Natural
gas really is your best energy value. See how it compares
to some of your other energy options.
Annual
Consumption x Local Rate = Yearly Cost x Average Life of Appliance
= Estimated Operating Cost
Billing Rates: Natural Gas = $.7961 per Ccf Electricity =

The following
assumptions were made in calculating the ESP:
- 2000
sq. ft. home (1). Based on DOE testing procedures.
- Furnaces
assume heating load only (2). Based on GAMA testing results.
- Heat
pump assumes a 3 ton unit (3). Based on current rates, case
PUE 980287, subject to refund.
- Normal
weather (4). Second rate block used, assumes baseload.
