We have a Thelin 3000 wood pellet stove with backup battery (which I recommend) and we are in our fourth year of using it. It replaced a no-name wood pellet stove that came with the house when we purchased it in 2000 and it was of very poor quality. Once the Michigan winter hits I burn it from approximately 6 PM to 630 AM each weeknight and essentially all weekend long beginning Friday night with a few hours off on Saturday and Sunday morning. I am now experienced enough to know what happens when good vs. poor quality pellets are burned by the three following indicators: amount and color of soot on the glass, the amount of ash buildup and the heat output. So my question is, What is the purpose of the Pellet Fuel Industry? I had wrote them recently suggesting that each brand they give their seal to reveal their wood source and wether bark is included, ash content, fines content and BTU rating. I doubt my input would change the industry but it seems to me a standard of some sort would be appropriate. If you have ever burned poor quality pellets (even though every brand I ever purchased says "Premium Wood Pellets" on each bag) you'd know what I mean. Another option would be to list on this forum wood pellets that each of us have found burn well and which did not. Any thoughts?
