Hi, I bought 3 tons of the Maine,s choice this year from lowes. I have had my stove tree seasons now and burned several brands of pellets. I have a harman 25 which works very well. What I found was much more ash than most other brands I have tried.I empty the ash pan twice a month or more with your pellets compaired to once a month or so with other brands. I bought these to support a Maine product, can,t say i,ll buy them againe unless the product improves. I have talked to many people about pellets and the have the same problem with yours and other Maine pellets. I am now mixing with the ton of penningtons from last year and has helped with the ash build up.Would love to here from you before I just take you off my list of choices.
