We recently moved in a "new to us" home and bought the Jotul 550 to fit into the existing fireplace. Several factors went into this decision - the price of oil, the BIG existing firebox, the open floor plan, and the vaulted ceiling opening up to the 2nd floor. I think we are feeding about 1800 sq feet ... I think (we have a baby and I do not have much time for Math or anything else lately). Anyway - this Beast arrived before Christmas and I have been struggling with expectations vs. how to best work it. I can get the unit hot (400 or so as measured on the pipe) but the fire seems to be on the down cycle by the time the house gets warm? I can get the thermostat to hover at about 68 or 69 degrees when it is 0 - 10 outside, which is ehh OK.... but maybe I need to employ a different tactic for hotter more prolonged heat? (here is where I may be expecting too much). Since I am heating a larger space with a unit that takes some time to get humming, do I need to somehow prolong the cycle? Does this mean that I should just keep feeding this Beast like a locomotive until I get the desired results, then throw on my big logs and put her on simmer? I am use to a smaller wood stove in a smaller space - so perhaps I am just being gun shy in my use of wood? The firebox of an insert definitely is more "squatter" (fatter but not as tall) than a wood stove ... so that seems to be throwing me too... Is there a more efficient technique I should be using?
