My wife and I are in the process of buying our first wood burning insert. We are most likely going with a Lopi medium flush mount on an existing exterior wall fireplace. The salesperson we are dealing with states that a blower only heats up 5 feet in front of the insert and doesnt actually push alot more heat through the house. He also states that they are not worth the noise they generate. We are not using our insert to exclusively heat our 1200 sq foot home but would like to benifit from the heat it will generate. So my question is, is a blower necessary to optimize heat output or not? Thanks in advance from an insert newbie.
