Electric heat can reduce your customer’s heating bills by up to 50%! Electric boiler total installed cost is up to 50% less than Mod/Con gas boiler! Monthly savings from electric vs. gas heat can pay for electric boiler retrofit in less than two years!! Uses Domestically Produced Energy!!! Electric Boilers What is Happening with Energy Prices? Electric Boilers What is Happening with Energy Prices? Electric Boilers How Do We Compare Energy Prices? Electric Boilers Get to Know Your Local Rural Electric Coops and Utility Company Programs Electric Boilers Electric Boilers Electric Boilers Electric Boilers Electric Boilers Electric Boilers Electric Boilers How Do We Compare Propane Rates vs. Electric Rates? Electric Boilers Compare Propane to Electric – Cost Per Million BTU’s Electric Boilers Current Propane Rates Propane Company Location Current Price per Gallon Amerigas McCall $2.62 Suburban Propane Twin Falls $2.90 Suburban Propane Boise $3.30 Suburban Propane Elko, NV $3.32 V-1 Propane McCall $2.59 AVERAGE PRICE $2.94 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 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 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 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! Electric Boilers Why Electric Heat ? Reduce winter heating bills by Switching to Electric!!!! Electric Boilers Why Electric Heat ?
