This is my first full season with the pellet stove (Harman Accentra Insert) and purchased 3 tons of GS. I know there is mixed opinions of these pellets, but I purchased them for a good price with my neighbor who also has a Harman and he tested them out. I know I broke the rule of trying a few bags before you buy a significant amount, but I was wondering if it is common for bags of same pellets from the same ton to burn at different temperatures? I have gone through about 7 bags so far. The first five burned at an ok temp, not as hot (it seemed) as the Logik - E I used for about 2 bags last year. But the last 2 bags of GS have been much, much hotter than the first 5 bags. It increased so much that I was told to turn it off by my wife. The only difference between the first 5 bags and the last two is the stove has more ash because I couldn't clean it this weekend and I slightly adjusted the feed rate from slightly below 4 to slightly above it (minimal change). I have the stove on room temp mode at around 72 degrees so I would assume it would keep the rooms around similar temps, but it seems much warmer. Would this slight adjustment cause this much change in the heat output? If not, what could be the cause. Don't get me wrong, I'm not complaining, just curious. If it keeps it up, I'll feel much better about my purchase of the GS.
