Sounds very cozy!
It's not cozy outsize right now. The thermometer outside my window reads -4.1 F. The official temperature in town in -7 F. The dew point is down to -11 F. That is as cold as it can get...unless the dew point drops further. There's another 6 hours before sunrise. Plenty of time to cool more.
My upstairs office doesn't have any heating or cooling. I'm going to leave the computer running all night to keep the room from getting too cold.
