If snow in early November is a sign of a cold winter ahead then hang on to your mittens. But even with minus 9 every indication points to a roasty toasty GeoStudio. This video was done while I had my electric 1000/1500W heater plugged in and set to ‘low’. As you can see the dome easily stayed at room temperature. Two reasons for this are the high insulation of the floor + walls + dome. The entire structure is enveloped in foam insulation giving it close to "R20" insulation, the equivalent of a new, standard house. Also, the shape of the dome allows the inside air currents to flow more easily meaning fewer drafty cool spots and a more even distribution of warm air.
Incidentally, electrical use to heat the GeoStudio on a -15 degree night will be about 7 kwhr, so the cost based on 4 cents per kwhr is well under a dollar a day. :)
Anyways, enjoy the one minute video!
