I thank you for the compliment. If I lived someplace really warm (a relative term, I know), and the rest of the house worked, and the view justitfied it, I could see that design. Here's an example: http://www.luxist.com/2007/02/10/soaring-osprey-estate-of-the-day/ Of course, there may be a good reason the place is on the market. I'd love to know what their heating bill is. OTOH, here's a house design that was able to get a lot of the effect of the cathedral ceilings without the cavernous heat reservoir up where no one can make use of it. Actually, I find this house holds a lot more charm for me, but then, that's me: http://www.sanjuanwaterhouse.com/pages/photos.htm But a cathedral ceiling in Fairbanks on a single-parent budget? Not. Those numbers were about three years ago, so that might account for part of it. Is your house very large? That could clear up the mystery, in part. The more-or-less R8 walls would also make it harder to heat, and the logs contribute a lot of thermal mass to boot. Wonderful when your stove is cooking and the log walls get warm, but a shivery feature until that point. I know that you wanted it to work, and it was mystifying to me why it didn't. I'm glad you have a solution that works for you at last, and best wishes for a warm winter with it this year. Not here. The summer has turned, and there is an autumnal bite in the air, without a doubt. Burning season is soon upon us, and I have this weekend slated for bringing in a lot of that seasoned poplar laying around my property. It's now or never. I've seen winter come as early as Sept 5th (once) here, so time to make hay while the sun shines.
