I have burned so called ‘premium’ pellets for years, but for some reason never ran into yours. I needed pellets on the 1st cold morning and went into Lowe’s. These Sierra Supreme pellets are by far the best starting and hottest pellets I have ever seen. My stove is on a small ship. I think these pellets will be hot enough to keep the diesel boiler from coming on. So far, I’ve only burned on the lowest setting and the stove drives me outside. I plan on buying a full winters supply now.
