I grew up in an old house that was a converted tobacco barn. We had a propane blower. Located in the middle of the house on the main floor. I went to bed with lots of blankets and a toque. Really cold up stairs. Mom would put our clothes in front of the blower so they were warm when we woke up. Anyway, I was used to temps closer to 55-60. Now in this place we are happy Around 62-67. Can't imagine 70 or above. Too hot.
