I see the ultra-long burn times as a bonus side effect of having a thermostat. The primary advantage of the thermostat is that it automatically increases air as the fire is waning, to keep heat output even through the burn.
Nothing is more frustrating to me than having the house warm all day while we're away at work, and then cooling in the hour or two just before we get home. That's how life was with my Jotuls. The house was always warmest when we were away at work or upstairs in bed, and cold again when we woke up or got home.
I can understand why that is critical with your house. My house is insulated and air sealed well for what it is. However, it is 2x4 stick built. R13 insulation in the walls only gets you so far when its -2 with a wind chill of -20. You are not far from me so I'm sure you see some of that too. My stove never disappoints and the house is always warm even after 10-12 hour work days with nobody else home.
