Hi: Just a general question concerning pellet quality and to solicit opinion. I am new to pellet heat and have ordered 3 tons of Lakewood premium from a local building supply at $265.00/ ton. A bought a few bags just to test out and notice that they don't appear to burn as cleanly as the 2 bags ( Lacrete premium) my stove retailer supplied with the stove, his price is $300.00/ ton( no supply issues). The glass dirties and there is noticeable dust on the chute leading to the burn pot. As the test bags were last years stock is it possible that is the cause or are they just inferior to the other brand. The specs on the bags are nearly the same. I don't want to get caught with 3 tons of poor quality and would rather pay the extra to get the best results from my stove. Appreciate your advice.
