Pellet stoves burn recycled materials at a high temperature that makes it cleaner and more efficient than wood, and they are easy to operate. The stoves and bags of pellets are small so they don't take up much space in the home.
Wood stoves create lots of ash and creosote, which occurs with combustion and is flammable. Pellet stoves burn much cleaner than wood stoves, with very little creosote and fewer pollutants. The amount of ash created by the stove depends on the grade of pellets used. Pellets are relatively inexpensive and available in smaller quantities than wood.
Pellets are made from leftover materials that would otherwise be thrown away, such as sawdust, peanut shells, corn and wood shavings. The pellets used as fuel are compressed so much that very little moisture remains. The low moisture content allows the pellets to burn hotter than wood. Pellet stoves typically burn at an efficiency of between 75 and 90 percent.
Many pellet stove models are self-igniting, making them simple to operate. Many also have thermostats that control the stove's operation. The unit cycles on and off as necessary to maintain the temperature. They may have safety controls that identify problems as they arise.
