Has anyone made the switch to Pellet Stoves? Pellet stoves run on wooden pellets made from saw dust. these pellets are cheaper than Oil. However, these stoves require weekly cleaning, and pellets take up a large amount of space. My family has a pellet stove. We consume about 5 tons of the stuff every winter, but it is cheaper than oil, and we've saved alot of money. Anyone else use pellet stoves?
