How Do We
Compare
Propane Rates
vs.
Electric Rates?

17. Electric Boilers
Compare Propane to Electric – Cost Per Million BTU’s

18. Current Price per Gallon
Electric Boilers
Current Propane Rates
Propane Company
Location
Current Price per Gallon
Amerigas
McCall
$2.62
Suburban Propane
Twin Falls
$2.90
Boise
$3.30
Elko, NV
$3.32
V-1 Propane
$2.59
AVERAGE PRICE
$2.94

19. Using the Cost per Million Btu sheet to sell the concept
Propane : Cost comparison
Current average propane cost = $2.94 per gallon
$2.94 per gallon with a 90% efficient device = $35.70 per million BTU
Inland Power Electric Rate = $.0575 per kW
$.072 per kW = $16.85 per million BTU

20. Compare Annual Heating Bills
Electric Boilers
Compare Annual Heating Bills
Propane vs Electric
Assume 1,500 SF ranch home with full basement. 3,000 SF total heated space
Assume 1500 gallons of propane per heating season
Assume $2.94 per gallon and $.0575 per kW

21. Compare Annual Heating Bills
Electric Boilers
Compare Annual Heating Bills
Electric vs. Propane
1500 gallons X 91,500 btu per gallon of propane = 137,250,000 btu’s
137,250,000 btu’s X 90% = 123,525,000 btu output with propane
123,525,000 ÷ 3,413 btu per kW = 36,192 kW

22. Heating with Electric vs. Propane
Electric Boilers
Estimated Annual Savings
Heating with Electric vs. Propane
1500 gallons X $2.94 per gallon of propane = $4,410 cost of heat
36,192 kW X $.0575 per kW = $2,081 cost of heat
$4,410 - $2,081 = $2,329 annual savings!
52.8% annual savings!

23. Why Electric Heat ? Electric Boilers
Reduce winter heating bills by Switching to Electric!!!!

24. Why Electric Heat ? Electric Boilers Retrofit Market Opportunity

29. 34,000 btu radiant floor heating system
Electric Boiler vs. Gas Boiler Installation / Material Cost Comparison
34,000 btu radiant floor heating system
Fossil fuel boiler requires venting and gas piping

30. Why Electric Heat ? Electric Boilers
New Construction: Reduce Boiler System Total Installed Cost
New construction - radiant in basement, 34,000 btu load:
Electric boiler: 10 kW $1,022
Mod/Con gas boiler: 50,000 btu input $_______
Add for gas boiler installation:
Gas piping, Venting
