This will be our second season with the lopi liberty which replaced a 16 years old medium sized Dutchwest stove. It was a toss up between the lopi endeavor or the liberty. We heat 2,400 sq.ft primarily with wood. This stove is a heating machine.We have already have a couple of fires this heating season. It keeps the living room with is 25X14 between 80 and 90 degrees and the rest of the house 75 to 80 degrees. We like it hot. The only thing i don't like about the stove is the shallow firebox, but we stared to cut the wood to 14 in. so we could load N/S which gives better burn times and hotter burns. It is almost impossible to keep this stove under 650 degrees on the stovetop thermometer with just 3 or 4 pieces of wood which is bone dry oak, locust, and ash. I usually reload at about 350 degrees let it get to 425 or so then start shutting it down it stages to almost closed at which point it goes into i call nuclear mode. The first couple of burn it was very scary. Now i just shut it down and let it cook checking on it from time to time. My middle and front air tubes usually start to glow at 500 degrees which i was told this was normal. They glow anywhere from a couple of minutes or for the entire burn Does any other lopi users air tubes glow for long periods of time. Also would like to now it any lopi users have had any issues with the baffle angle irons, air tubes, roll pins falling out, bypass issues, or door issues so I know what to expect in the future. This stove in built like a tank so I hope i will last another 16 years. Any info or hints would be greatly appreciated.
