I'm new to heating with pellets, I have a 10-CPM that I got from AM-FM energy this past summer and I'm very happy with the stove. Here in Maine it's starting to get cold enough to run the stove at least part of the day and while I was waiting for my ton of Corinth pellets to arrive I bought a bag of Green Team's at Lowes, which is a pellet that seems to not get very favorable reviews. I had nothing to compare it to until I started burning the corinths, and what a huge difference - a lot more dramatic than I would have thought. I got way more heat from the Green Teams - on setting one the blower ran constantly. With the Corinths on setting one it rarely gets hot enough to run the blower, and on setting two the blower cycles. At least at the higher settings I should go through the ton pretty fast when it gets really cold and I can move on to another brand. I had no idea there was such a big difference.
