i am planning my stove installation. i had thought that ducted replacement air was needed for best efficiency. as otherwise, the stove would suck heated air out of the house = much like a regular fireplace does. but i was reading on the web, that that is not the case. but, the stove does use air from the house, and moves it out the chimney. how is a stove better than a fireplace ? idk if i am asking my question properly. i am concerned about replacement air.
