ARC08, Our new home just faced another first.
Mid day on January first we turned off the lights, turned off the heat, and headed for the cities.
The temperature January second reached 32 below zero.
January third woke up to 31 below.
After more than two days of bitter cold weather with no heat, the house temperature was still 66 degrees.
I like my ARC!
ps... I have to remind myself that it will get better. This is an unfinished ARC that has no solar panels and no air exchanger, so we still have some windows open.
