I had a PM a while back from someone looking for good info on getting longer burns from the C450. At the time, I had never had any such luck, but now things have changed. Early this fall, I had a liner changout for a 6" insulated flex in my internal brick chimney, and still had lots of wood from last year. Now, with the cool temps and more consistant burning, I am able to get overnight burns that leave me with ample coals for an easy restart in the morning (8-9 hours after the reload the night before). That, and I'm not overheating the house at night. I like it cool when I sleep, so trying it with warmer outside temps back in Oct didn't make sense.
Basically, I am getting the flue warm over the evening of burning, reload the stove at 11pm (filling it to the brim) and getting it burning hot (650*F on the stove top). then I start to bring the air down until I have just the secondaries burning (air control all the way closed), then go to bed. Most nights lately I have even left the blower running on low, and it is still going in the AM (0730). In all, I have 7-8 hours of unattended stove and good coals for restart - not a true 8 hour burn time, but 8 hours of warm nonetheless.
The change has been the flue, wood, and the cold outside temps to keep the draft going to allow the clean burn (no black glass in the am). I had zero chance of getting these results last year (5” uninsulated flue with barely dry enough wood)
Hope that helps those looking for results, and gives some hope to those who don't have the ideal wood to do it this year. Get some dry wood (order it now), and next year will be even better!
