im surprised you can get that low MC in Seattle. Not sure even my 4 y/o ash is under 14ish% Too muggy here in STL.Recently installed BK Princess. I'm comparing today with the last week or so. Wood is around 12%-13% MC. Using about a 1/2 load.
During the last 7 days, the outside temps were mostly low to mid 50s. The NG furnace is off overnight; the space (1800 ft^2 with 13' cathedral ceilings) is generally mid-60s in the morning. I've been getting it to mid-70s in a couple of hours with the stove air control on low (about 3:30 to 4 o'clock) after the startup procedure, and then it stays there for 12 hours before starting to drop off. Today I had it at 4:30 and the space was still only 69. Did a small hot reload at around 3 hours, turned the stove to 6, and reached 76 after an hour. Turned the stove back down to 4:30. Lost a couple of degrees.
It isn't a problem. I can get the room temps I'm looking for. Might not be worth using the stove at all at this point, but I'm learning. I'm just curious why today was different from the past week. Could be that I pulled out splits of a different species of wood. Maybe I placed the splits differently. Maybe it's just Thursday. The most blatant difference was the impressive amount of rain in the past 24 hours. No reason to think that it's related, but plenty more to learn about using this stove.
