I am new to pellet stoves-but after just a couple of months am completely impressed with the amount of heat our very old (1993)Breckwell puts out. However, I underestimated how many pellets we would go through this year. After a couple weeks of trying I just found out that our local Agway actually has some pellets-but they are the non-premium kind ($218/ton). I still have about 35 bags of the premium pellets and am wondering if mixing the premium with the "bark" pellets might minimize the problems. I was going to buy a single back to try it first. Any suggestions?
