I think this is the latest in the year that I've fired up the Kodiak! But then this year was the latest I kept her running (into May).
Whenever the outside temp doesn't reach 70/50, I try to explain to my DW that the stove that costs pennies per day at this point needs to be used vs the dollars per day oil burner. The Kodiak idles forever at 100 degrees off the sides.
Windowstats work well, but I must admit the drone of fans IS annoying. It's met with frowns and final submission, and 2 days later she's warming her butt against it. (always a point of needless contention, and not a major arguement).
Hmmm, I'm thinking Thursday...
