I have a question that has been bugging me. I have made a spreadsheet with the electric usage since 2005 which was the year I decided to buy the Harman Accentra, that was installed in late feb/06. So I am tracking all the monthly electric bills and also all the bags purchased, which gives me a pretty good idea how much heating my place costs. I have to say that the fuel calculator does not come close to my annual usage. The fuel calculator projects savings compared to electric baseboard of approx $800.00, which would be quite accurate if I got the pellets for free, otherwise I am pretty much breaking even, I bought 140 bags this year @ $4.69/bag unless I end up using less than 140bags this season (chances are slim). Anyway, I was wondering what would you compare this years cost to? Do you compare to the year before you got the stove (2005) or last year, ie 2006 to calculate what your savings are? Just for info, my excel file has the 2005,2006,2007 monthly kilowatts used, the kw price and number of bags purchased. What I do then is I take the monthly usage for 2005 and 2006 and apply today's rates to calculate the savings and applys the price paid to buy pellets to get the final picture. Is this the right way to do this?
