How is it unbelievable? The sun shines through the windows and warms
up both the areas used by the occupants and the stone/concrete walls
The sun stops shining, the walls and floor are still warm because of
the insulation *outside* the concrete/stone mass meaning that the
majority of the heat 'loss' is to the usable building space.
Tweak the interior heat retaining capacity of the stone/concrete and
reduce the losses through the insulation and windows to the outside
world and the house could stay warm for weeks, do it right and use the
additional gain from the occupants and their appliances and there
might be zero requirement for additional heat.
It's not rocket science just sensible design.

Yes, we had a 5*F morning several years ago, no back up heat, and 658F
was the coldest temp seen inside my house in the 22 years I`ve lived
in it. Many similar experiences, search the net, it`s done often, just
basic solar design, south facing glass, thermal mass, insulation. It
works, I have a book showing 2,500 years of solar design, you are well
behind the times. Doug

Isn't that a tad warm? :-)

He's been burning books to stay warm.
