16How Do We Compare Propane Rates vs. Electric Rates? Electric BoilersHow Do WeComparePropane Ratesvs.Electric Rates?
17Electric BoilersCompare Propane to Electric – Cost Per Million BTU’s
18Current Price per Gallon Electric BoilersCurrent Propane RatesPropane CompanyLocationCurrent Price per GallonAmerigasMcCall$2.62Suburban PropaneTwin Falls$2.90Boise$3.30Elko, NV$3.32V-1 Propane$2.59AVERAGE PRICE$2.94
19Using the Cost per Million Btu sheet to sell the concept Propane : Cost comparisonCurrent average propane cost = $2.94 per gallon$2.94 per gallon with a 90% efficient device = $35.70 per million BTUInland Power Electric Rate = $.0575 per kW$.072 per kW = $16.85 per million BTU
20Compare Annual Heating Bills Electric BoilersCompare Annual Heating BillsPropane vs ElectricAssume 1,500 SF ranch home with full basement. 3,000 SF total heated spaceAssume 1500 gallons of propane per heating seasonAssume $2.94 per gallon and $.0575 per kW
21Compare Annual Heating Bills Electric BoilersCompare Annual Heating BillsElectric vs. Propane1500 gallons X 91,500 btu per gallon of propane = 137,250,000 btu’s137,250,000 btu’s X 90% = 123,525,000 btu output with propane123,525,000 ÷ 3,413 btu per kW = 36,192 kW
22Heating with Electric vs. Propane Electric BoilersEstimated Annual SavingsHeating with Electric vs. Propane1500 gallons X $2.94 per gallon of propane = $4,410 cost of heat36,192 kW X $.0575 per kW = $2,081 cost of heat$4,410 - $2,081 = $2,329 annual savings!52.8% annual savings!
23Why Electric Heat ? Electric Boilers Reduce winter heating bills by Switching to Electric!!!!
24Why Electric Heat ? Electric Boilers Retrofit Market Opportunity Existing propane boiler, whole house HW or radiant floor systemRetrofit to electric to take advantage of low electric rates from Electric Coop
27Why Electric Heat ? Retrofit Market Opportunity Electric Boilers Assume $2,500 total installed cost of electric boilerElectric comparison – save $2,081 on heating billsRetrofit boiler installation with existing propane boiler, payback in less than 2 years!
