Wood pellet heating for residential & commercial
Focus on Energy provides a fact sheet on heating with wood pellets:
Pellet fuel is a biomass energy product made of wood residue or other plant materials. Most pellets are made of hardwood sawdust originating from wood waste products such as pallets and wooden packing materials, or from the waste produced by manufacturers of furniture and other wood products. Pellets can also be made of crop waste such as corn stalks or straw, or even waste paper. The wood waste or other biomass is pulverized, dried and compressed into pellets.
Pellet fuel has several advantages over cordwood, woodchips or other forms of wood as heating fuel because the consistent manufacturing process produces a uniform fuel source. The moisture content of pellet fuel is lower and more uniform, and it produces more heat per unit of weight, making it a more efficient fuel. It also burns leaner, and takes less space to store, about four to five times less than that of cordwood by weight.
