So, I've gathered that the Jotul F 3 CB is NOT really an "overnight" burner. BUT I'm curious about everyone's realistic burn times. I'm in Ohio and will have my choice of mixed hardwoods. I imagine I will attempt to burn the "softer" woods while awake and will use normal splits for this. What I'm wondering is what do you think of having a separate cache of seasoned oak rounds for the last fire of the night. If I load her up with oak rounds instead of splits before bed, what do you all think I can expect for a burn? Chimney is 30 ft but I will be putting a damper valve inline. I don't want to get into the habit of "smoldering" overnight and building creosote, unless it will balance out with a hot morning fire to burn the deposits up. Does this sound logical? Even with this thought process, what do you think is realistic? Thanks everyone. I hate feeling like I ask silly questions but there is so much information here(and I'm a research geek) that I can't get to all of it.
