We just got our fuel analysis from the gas company for the period Dec. 18 - Jan. 20, 2011 versus Dec. 20 - Jan. 19, 2012.
Subtracting the amount "saved" due to three fewer days in the billing cycle and factoring in the average daily temp (33.9 in 2011 vs. 37.5 in 2012), we still saved approx. 46% on our heating bill compared to this time last year. Our insert was installed and fired up on Dec. 6, 2012 (umm, bonehead moment: try 2011. Sheesh).
I acknowledge some slipperiness in these stats. We heat hot water and cook with gas, for example, and still use the gas furnace when the Regency is not in use. And there are some aspects of the gas company's calculations that don't look super-accurate to me, but I like the general trend.
And yes, I know that trying to amortize the full cost of the stove and its fuel requires a very long view, but as the title says, that wasn't our primary goal. Alternate heat during power failures, ability to use a crappy, shallow fireplace without air conditioning our house [g], and the aesthetics, were all higher on our list, so any displaced gas use is just gravy.
