Here on PEI we don't have a lot of choice in Pellets, my experience is with Shaw's Eastern Embers which seem OK. The ash is fairly gritty though. I have tried a few bags of LG and something else and all seemed pretty comparable. I guess I am comparing them with the ash from a regular wood stove....which to me always seems powdery and very smooth, not at all what is seem to get from the pellet stove.....although I must admit that there is certainly less ash volume from 40 lbs of pellets vs 40 lbs of wood....maybe there is a comparable amount of gritty material in the regular wood ash it is just diluted in more ash... any comments?? what is the residue like from really good pellets?
