Jack and Ruthie, Arcadia homeowners in New Hampshire, report that:
"This morning it was -4° outside and inside the envelope it was 66°, including the cellar. Our thermostats are set at 65° for our radiant backup heat so the boiler didn't come on much. Right now it is clear and sunny, 2° outside. The sun space is 76° and the South, interior log wall, French doors and all of the interior windows are open. We have a couple of ceiling fans running. The temperature inside the envelope is at 70° now and may go up a degree or two before we close the French doors about 2:30."
