The only insert i would consider is one that has heat exchangers built around the sides n back..essentially, .a single united network of heavy duty steel pipes that usually have a quiet fan blowing the hot air inside of them into your house...ideally, you are also using outside air as your air source for controlling combustion..I've seen some pretty tricked out systems where the outlets of these exchangers have been routed out into the room and are heating the space very nicely...you dont need much in the way of exchangers...the air in those things gets very hot in a firebox situation
