Yes, there are differences in pellets that can affect the performance of your 1700 Sq. Ft. Pellet Stove with 90 Lb. Hopper. Here are the key factors: - Hardwood vs. Softwood Pellets: Hardwood pellets tend to burn slower and produce less ash, while softwood pellets burn hotter and may create more residue. - Pellet Size & Density: Higher-density pellets provide longer burn times and consistent heat output. - Moisture Content: Lower moisture levels (below 8%) improve combustion efficiency and reduce clinker buildup. - Additives & Quality: Premium pellets have fewer fillers, leading to cleaner burns and less maintenance.
