I've had lots of experience with stoves but none with inserts and I'm looking for advice. My son lives in the Seattle area and just got a new home, it was built in the 30's and has a fireplace with an external chimney. He is looking for something for supplemental heat, what would be a good insert that wouldn't lose heat to the outside, but also would not need a fan.
. I picked BK Princess over Lopi primarily because of the the ability to burn for a longer duration but if you only want the insert as a supplemental heat source then Lopi and others are an excellent choice.
