Hi folks - I am new to the pellet world with a Harman Accentra, which is a great stove. Heating a 2,700 sq. ft. expanded Cape with good (in the new part) to poor (in the old part) insulation. Stove has met expectation, not oil-independent but have cut oil use dramatically. And house is much more comfortable. We received 2 tons of Maine Wood Pellets with stove. I knew these were more shoulder-grade pellets. Heat was satisfactory, ash seemed a bit heavy but I had nothing to compare too. After reading reviews and speaking to the local pellet distributor I tested American Wood Fiber and Barefoot pellets. My unscientific observation - definitely an upgrade. Both produced a higher grade of heat. And the BIG obvious - way less ash and a much cleaner stove. The glass is still clean after a week. You can see the difference when you dump the pellets in hopper, virtually no dust. Now granted, the difference in a ton of the premium pellets to the shoulder is $30-40 a ton, maybe more if you go big box store. For me,I find it worth the added cost. But that's just me. Still looking for a good shoulder pellet that has reasonable clean burn for the April/May timeframe. Good luck everyone.
