I've burnt TT Hardwood Heat, Energex & Maine Athens . Thank God i still had a dozen Energex bags left & that is what i'm burning right now. They burn like i suppose a great pellet should . Started burning what i have left of them yesterday morning . Too bad i still have 3 ton left of my Athens left . Their the early first ones out & really suck . But this spring, i'm gonna be purchasing Energex . Good luck to everyone with their stoves & pellets thru this cold spell . Muss
