My Own Thermostat Challenge

I read about it all the time in various homesteader and eco-minded publications--"the great thermostat challenge." The gist of it is usually the same: how low can you go?? Can you handle turning your home's temp down from 72 to 68 or whatever? Can you put on more socks instead of heat?
Well I have my own challenge this year, and it's quite the opposite. Can I handle turning the thermostat up???
I propose this challenge for my own family not because we like to waste energy or money, but simply because we want to live through the winter. The family of Icy Jane would win the silly thermostat challenge almost every stinkin year. Simply because we reside in a sunless arctic climate, where the temperature is known to hover somewhere around -18 F for weeks at a time. We get zero solar / sun heat for the four coldest months, and have an old claptrap home, that is just plain futile to try and insulate.
The resulting situation is as follows: we heat with wood at night and turn off the "stove" (the only mechanical heat source in the house is one propane monitor stove in the living room). Of course by 7:00am, even with an awesome wood stove--the temp in the living room is back down to 48 by morning (or much lower--the thermostat indoors stops at 48). Not to mention the unheated bedrooms, which usually have ice in all the closets. It is quite amazing to include shaking ice off clothing as part of ones' morning ritual. Then we all jump up and down and complain for five minutes while huddling in front of the monitor stove. (including the dogs that run in frisky manic circles)
Getting too close to this little power house stove results in weird burns on my back, but it's a small price to pay, in order to actually feel heat.. After putting on two pairs of socks (one wool), long underwear and sweaters, we hop around the house some more times and continue complaining.
I do set the stove to 62 degrees--but that seems to be the temperature only in the living room. The dining room usually hovers around 52. We actually have friends in Anchorage who have told us point blank, that they refuse to come to our arctic hell hole for dinner. (they did try, bless their hearts, to pack slippers and sweaters a few times)
So our new lifestyle of choice is seeing if we can handle setting the monitor stove to 66 instead of 62! The thought of it seems so luxurious and foreign I don't know if I can handle it at all. It will certainly cost us more money, and even at 66, the bedrooms will still be icy....but if I have the gall, I may just try it this winter.
