Pellet Stoves

Pellets, which resemble rabbit food, are fed into the appliance's combustion chamber automatically, often controlled by a thermostat. Heat is usually delivered by a forced air system. Pellet-Burning Stoves
Pellet-burning stoves are fueled by wood pellets which are made from compressed wood and such agricultural waste as rice hulls and corn husks. Pellet-burning stoves operate around 75 to 80 percent efficiency and can be refueled into a hopper which can hold between 35 and 150 pounds of fuel pellets. Pellet stoves can be either free-standing units or fireplace inserts vented into an existing chimney.
