If I am trying to bring the house temp.up from 60 deg. F to 70 deg. F. is it better running the stove with a few splits and a lot of flame or putting stove in secondary burn (damper closed) once I have a nice coal bed and stove top is 500 deg. F. or more? My first thought is that with the roaring fire the room temp. should rise faster but I am willing to bet that I am wrong. The Vermont Castings manual doesn't talk about different situations like this. This stove is new to me and my first with a secondary burn.
