I’m sitting here in front of the computer in shorts, a tank top and flip flops. It is 75 degrees in the cabin down from the 79 it was in the “heat” of the day. That is what passive solar can do. While I spent the day reading a book with my legs basking in the sun shining through the windows I had a false sense of temperature. When I took the dogs for a walk I found out that it really was cold out side and the wind made it feel even colder.

There is nothing “special” about my cabin it just has good insulation and big south facing windows but that is enough to keep the cabin warm during the day. Even if the wood stove is off or kept very low (like today) on a sunny day the heat pump does not come on at all.
