Not sure if I'm more surprised at the 19 cords or the one cord.
I average between 3 and 4 living here full time. Here in Northern New England this morning it's zero with a windchill of -18. Yurt temp is 44 at 7am and I'm pretty bundled up waiting for the stove (& sun) to really warm the place up.
Jafo. Love the art! That is exactly the sort of thing we need to do. Probably can't get every draft, but fixing that particular draft will make your nights waaaay more comfortable. (Though that same draft may make your summer sleeping more comfortable!). I also have a fleece hat tucked in the head board to put on should I wake up cold. Makes a big difference. Also a piece of fleece to pull around one's head and shoulders fills little gaps you don't even feel, but are losing a lot of heat from under the blanket.
Like I've said before, I find hot water bottles ($5 at Walmart) a HUGE help. Heat up the bed at night, one on my lap in the AM while doing email, while reading at night, anytime I'm sitting and could use a little extra heat.
Perhaps more "work" than some would like, but I love being warm and toasty.
When I first read "cutting wood with the sun", I thought you had figured out some new system. Cut wood in the morning when there is less sap make the wood dry faster or cutting at night makes sappy wood burn hotter or something like that. (It's sapping time here so thoughts are on that.
