January Heat Bill Down 43%

Since we got our home air sealed and insulation increased I've been tracking the heat costs of this winter versus last year.  

January heat bill was down 43% from last year, however it was a little warmer this year compared to last.

January 2009 heat bill =$166
January 2010 heat bill = $95

January 2009 degree days = 592
January 2010 degree days = 563

I've now got 4 months of data from Oct 2009 through Jan 2010 to compare to last winter. 

Its been a little bit colder this winter:
2008 Oct - 2009 Jan Degree Days = 2,310
2009 Oct - 2010 Jan Degree Days = 2,390


2008 Oct - 2009 Jan Heat cost =$604
2009 Oct - 2010 Jan Heat cost =$398

Total accumulative heat savings $206 or 34%


With 4 months of data I'm fairly confident that the 30% savings we've been seeing is accurate.
