It's been 22 years since they bought their house, and this old Jotul has been a true champion all those years. Over the years, a crack has been noticeable in the door and a couple of days ago the spring assembly on the door hinge gave out. It's a real struggle to close the door now. They've ordered a JotulF3 CB and I'm wondering what sort of learning curve they will have. Although it takes 16" splits, it sounds like it has a pretty small firebox. My dad is all about stuffing in an "overnighter" and I'm afraid this might not meet his expectations in terms of burn time. But, at the same time, with a more efficient stove, I'm also concerned it might put out too much heat for them. I don't have the square footage of the area this will heat, but it will heat a relatively small area downstairs. Although this includes the kitchen, dining room and living room, this portion of the house was originally a camp and really is not as big as what you find in a typical home. The upstairs loft was converted into a TV room and is likewise pretty small. They made several addition to the house, but none that are directly affected by the heat from the stove. Is this a good stove given the few details I've been able to provide?
