It’s not even that much work, to be honest.

I wouldn’t run 6 fireplaces at once, maybe two or three at most, and aside from chopping and carrying the wood inside, there’s not that much work in it. Just set a few pieces nicely with a piece of paper (think jenga style more than a cartoon bonfire), se it alight. Let it breathe for a while, get a good flame, then fill 'er up once it’s going nicely. I mean, depending on how hot you want the room. I’d never actually shove them full, about halfway at most maybe. Then let it burn. Then fill it up a second and maybe third time in the winter, then just let it cool while stoking the coals.

It really doesn’t feel like work.

And now I’m nostalgic.

But yeah temperature would be the least of your worries as king imo. Perhaps not the least, but a small one anyway.

People don’t even need AC on the latitude I live in.

It’s basically two winters and August.

Literally for most of the year I wear the same amount of outdoor clothing, which is a lot.
