The most common sources of wood used for making pellets include sawdust, wood shavings, and wood chips. These sources are typically waste products from the lumber industry.
There are three grades of wood pellets, including premium, standard, and utility. Premium pellets have low ash content and high energy output, while utility pellets are lower quality and have higher ash content.
The ash content of wood pellets can affect the performance and maintenance requirements of the heating system. Higher ash content can result in more frequent cleaning and maintenance.
Wood pellets can last for several years if stored properly in a cool, dry place. The lifespan can be affected by factors such as moisture and exposure to sunlight.
Wood pellets have a lower carbon footprint compared to traditional heating fuels, as they are a renewable energy source. However, the sourcing and transportation of wood pellets can have negative environmental impacts if not done sustainably.
Wood pellets can be disposed of in a compost bin or used as a fertilizer for plants. They can also be burned in a wood stove or fireplace.
