Hello! Longtime lurker but I finally registered as I had to post on this thread! I've been using New England fine up until yesterday, when I grabbed 4 bags of Michigan Woods at Home Depot for about 5.00 per bag. Because it was cheap, and because it said premium. Black soot straight away, and it smelled horrible. Really bad. I keep the stove clean, i've never seen ash and soot like that from a new bag before. I shut down the stove, scrubbed / vacuumed everything down, and remove 20 lbs from my hopper. Fired up again with New England, and have no problems at all. I returned the three other bags to HD and got a refund, no questions asked. Perhaps I got a bad batch, but that's my experience with it. Won't buy again, obviously.
ps. many thanks to all the stove people on here who've helped me troubleshoot my way through three newbie seasons of a pellet stove. I survived last winter because of you guys
