kurt Posted January 10, 2008 Report Share Posted January 10, 2008 It didn't look all that strange, other than the electric part; I've only seen a half dozen electric boilers in my entire life. What are the utility costs for an electric boiler? Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted January 10, 2008 Report Share Posted January 10, 2008 here my rates are 13.8 cents a KWH 13.8X24,000= $3.32 per hour of operation. With fuel oil @ $3.00 + per gallon it's not as terrible as it seems at first glance. 24,000 divided by .3=roughly 80,000 btu's X.95 (average efficiency) 76,000 btu's per hour 115,000 btu's per gallon of fuel oil X.80 (average efficiency)= 92.000 btu's per gallon so: 8.77 gallons of fuel oil per million btu's divided by .8 =10.97 gallons per million btu's of usable heat and: 300kwh of electricity per million btu's divided by .95 = 316 kwh per million btu's of usable heat 10.97 x $3.00 a gallon = $32.91 per million btu's 316 x 13.8 cents per kwh = 43.61 per million btu's Quote Link to comment Share on other sites More sharing options...

Can you re-do your calculations to reflect that? - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Jim Katen Posted January 11, 2008 Author Report Share Posted January 11, 2008 Assuming Chad's numbers are correct for Mbtu/hr: The cheapest oil in McMinnville right now is biodiesel at $2.92 per gallon. Electricity, thanks to the local steel mill, holds steady at about $.04 per kwh so . . . Oil: 10.97 x 2.92 = $32.03 per mbtu Electricity: 316 x .04 = $12.64 per mbtu And now I know why folks in McMinnville like heat pumps so much. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
