We are going to see how long it can sustain the temperatures. They are not repairing the mini-split heater until Friday. But it's been amazing how performant it has been without having the heater on despite it staying so cold. We haven't used any heating or cooling (other than induction stoves, oven, computers running, body heat) for about six months now. It got warm in the summer. The main floor got to about 80 while the pitched roof in the upstairs got warmer. The house really wants to retain heat. But it's been incredible in the winter so far with it barely getting above freezing.
