The heat in that building hasn’t worked since we’ve been there. It was okay in the fall - even if we met outside because it was warmer than inside - but not working out now. By April it should be okay again!
When we first started heating with wood, I was surprised to find we needed fires more often in the spring than the fall.
I realized it was because the ground had frozen at least 2 feet deep, and that cold kept radiating into the basement long past the time the weather warmed up outside in the spring.
