Side effects of pellet stoves are dirt in the air and dirt in the house. Air is very dry, also seems people catch colds easier. My friend really liked her pellet stove, but quit using it because her house got so dirty and she always seemed to be catching or ending a cold breathing that air. She has a converted old Schoolhouse made into a home. Small, though she has a second story loft with two small bedrooms.
We have a wood burning stove, which we also quit using because of the dirt. Kids were always coughing, house was dirty. Along with the time needed to haul out ashes, haul in firewood and keeping the fire going while not home. We got a new furnace, which was really nice. All the coughing, dirt issues went away when we quit using the wood stove. All of us are much healthier these days!
Still have the wood stove, in case the electric goes out like in 2013 for 10 days. We now have a nice generator, but if it didn’t work, ran out of fuel, the wood stove keeps things around 50F thru the whole house. We can manage with that for an emergency time.
