Wood Pellet Stove are an alternative way to heat a home.

Wood Pellet Stove use wood pellets, which look exactly like rabbit food, and are made out of dried recycled compressed sawdust from lumber mills that otherwise ends up in landfills. They were invented in the 1980s and were popular for a while then declined some in the late 90s but since 9/11 have made a big comeback. The industry for stove manufactures, pellet distribution and stove technology has greatly matured and is nationwide.
Wood pellet stoves have a number of advantages over normal wood stoves. Because the stoves are so efficient, there is almost no smoke or creosote produced, in fact the exhaust is barely even hot so the stove doesn't need a masonry chimney and can be installed anywhere a tin metal liner can be put in, either directly into the roof, or sideways out a wall. They can be stand-alone stoves on legs in the corner of a room, or chimney inserts using an existing chimney. Unlike wood stoves, pellet stoves work well in urban environments because of little exhaust and no need for a chimney and can be installed in any room.
A fully automated stove requires filling up with the pellets and turning on; the stove does the rest: it automatically lights, automatically feeds the pellets into the flame with an auger, and automatically adjusts the rate to keep the room at a pre-set temperature with an electric thermostat.
