Pellet stoves produces less smoke than other wood stoves and you can keep them going on low, But you're pellets coming in from somewhere. Supply seems to be a problem in some locals....and there is some suggesting that natural gas is just as cheap, and less polluting.

There are people who claim that some of the scrap that enriches woodlots are now being gathered to produce pellets...robing the forest of future nutrients. True, I am not sure how eco=friendly pellets are?
