Very cool it stayed so warm! We were about the same here.

I got up this morning and discovered the wind had blown the back door open! Apparently it was closed at 3AM when my son tended the stove. It was 59F in my office though! Thank goodness for the wood stove, it had it up to 85F in an hour. It also heats this whole half of the house so I had to get it cranking for a while.
