Heating with wood isn't free, but it's worth it to me. Sometimes I enjoy the process, sometimes it's a pain in the ass... This year, I've been lucky. It's been warm and good network conditions to heat with Bitcoin miners. I'm in SW Michigan. Now zone 6 according to the new climate zone map.

I'm out in eastern Washington. Our wood heat is mostly supplemental until the power goes out. And it will.
