I have a 25-Pdvc for the past 3 years, it runs ok but can be inconsistent with it's heat output, Last year I ran BareFoot, I bought 4 tons but could never get them to burn right, very sooty and lots of clinkers and alot of ash, so this year I have tested a few, this is what I have so far, these were all from my Local Lowes, Somerset, burned great on 2-5-1 and 3-5-1, setting 2-4, very low ash, excellent heat, the ash was like fine powder, 18 hour from the bag and house was 70 with overnight of 20 and hight wind....Potomac, I was a little nervous burning these but surprised, very good heat, a little thicker ash than someret, had to adjust the feed rate, these fed rather screwy, 4-6-1, even with that, and a setting of 3-5, I still got 17 hours from the bag and the house was a nice 72 with an overnight temp of 18. I also tested Abuchons premeum pellet, they were just plain BAD, I ended up shop vacing out the hopper after 1 hour of burn, they more melted than burned, I still have Maines Choice and Fireside Ultra to test so I will update my finds but we are in for a couple a warmer days. I think the somerset were great but cannot find them, Also Lowes prices went up about 1.60 a bag.
