Note: I don't own any stock in any pellet mills. I'm only a consumer whom uses wood pellets for heat. Well, I picked up a dozen bags of woodfibers hardwood pellets. The bags were dry and the pellets felt ok. They state on the bag: 8000+ BTU's Dumped them into a clean Englander PVD 25. Had to break up a bunch of longs 3 to 4 inchers. No real big deal. The pellets lit normal, so off I went. Well after some time the stove went out. Not something this stove has done before without something seriously wrong. Turns out that they burn well but put out such low heat that the stove thinks it's out of pellets/ no heat. So, i have to burn 3 times the amount of pellets just to keep the sensor in the exhaust to believe It's still burning pellets. So 12 bags of woodfiber pellets now equals 3 bags of Firesides... My gues is that these pellets must have been made of hardwood that had fallen over 4 years back. Cardboard or corn cobs would have made higher producing pellets. I got ripped off! Don't let it happen to you.
