First let me give you a heads up of my house. One story open concept, 1200sq built at the end of 2003. Basement is not insulated and not finished either. Harman Accentra located in the are between the kitchen and the living room, facing the hallway to the bedrooms. Keeping Room temp @ 65 when nobody home and around 68-70 in the evening. I got the stove at beginning of march in 2006 and prior to that I used baseboard heating using programmable thermostats with the same temp usage. So without further due here are the results as given by my spreadsheet: Electricity Difference between 2007 total paid to 2005 total paid: -$609.86 Difference between 2007 total usage to 2005 total usage @ 2007 prices: -$805.22 So I've saved $609.86 in electricity comparing the Kilowatts used this year to 2005. If I apply electricity rates to the 2005 consumption then the savings would be higher assuming that it would remain the same (chances are it wouldnt). Now pellets: Price/bag Qty Shpng Total Date $4.69 16 $0.00 $75.04 Feb Gift card $2.00 16 $0.00 $32.00 Feb Cash $4.69 8 $0.00 $37.52 Mar Gift card $4.69 16 $0.00 $75.04 Mar Cash $4.69 7 $0.00 $32.83 Apr Gift card $4.69 1 $0.00 $4.69 May Cash $4.69 140 $70.00 $656.60 Jul gift card Total Invoice: $127.37 thanks to gift cards Without gift cards total: $1,121.44 Bags total : 204 (These are in Canadian dollars btw) In 2007 I bought 204 bags. Because it was my first time with a pellet stove in 2006 I had only bought 80 bags and as you can see it wasn't enough. Had to get another 32 bags to finish the heating season . The 140 bags are supposed to last me until the end of the heating season in this year of 2008. As you can see pellet prices have not changed thru out the year, the $2 purchase you see there was a special sale by the store because they were selling damaged bags from transport and I snatched all of them. You will also notice the Gift card purchases, I got them thru work rewards or from gifts from family. Which means I only paid altogether $127.37 for all these pellets, otherwise it would cost me $1121.44. So overall in 2007 I have saved $482.49 thanks to the gift cards. For 2008 I am expecting more or less the same electricity consumption at slightly higher rates. Hopefully 140 bags are sufficient, but prices have already gone up and these days they are @ $5.19+tax and based on this year that will be the price until October when it goes up again for the winter. Btw in 2006 I purchased pellets in August @ $4.29/bag. a whooping 21% increase in a year and half compared to only 16% for electricity for the same period of time. No wonder my initial calculations were so off, I would never imagine prices would increase so much for pellets and electricity, but more so for pellets. Oh yeah, I dont expect to get as much money from gift cards either.
