Well, Instead of jacking the stove up and abusing it when it gets cold. I just change to a pellet that produces more heat at the same setting. Once it warms again, I go back to a pellet that doesn't. About the same as raising lower stove settings, Just doing it with pellets. Not all pellet produce 8200 btu/lbs. Some more and some less if you check the PFI test results. So there is a slight difference. I have seen anywhere from 7900 to 8800 btu/lbs. Having the stat control the stove also helps as it only runs just enough to keep the shack warm. If I miss the forcast and don't change the pellet. Stove either runs longer or less depending on need. I prefer to have it run less with a hotter pellet in the cold. Warm weather and a shoulder pellet is where I save a nickle or 2 with a cheap box store pellet. Boxstore pellets are $209/ton and the cold season stuff is over $280/ton! Hence my theory for shoulder/cold season pellets. Nothin better to do anyway while sittin inside when its cold out, So playing with the stove/pellets gives me something to think about. Just a game and a chance to save a little. more money I save, More money I spend on fishin gear and toys!
