As is pointed out above, a lot depends on the house construction and your comfort level. I set our Tstat at 10C (that's around 50F). The furnace is in the basement so the basement temp is about 1C warmer than the main floor (because of the furnace and ducts are located there). The Tstat is web enabled and I can remotely check the temps in the house (basement and main floor)each minute via the web, and our house checker and I get an E-mail warning if the temp goes below 8C. We've had some cold nights (around 0F) and the furnace runs only for 5 minutes every half hour to keep the temp above 10C at these outside temps.
I moved the temp up from 8C last winter to 10C this year because of the the ice storm we had last winter, power was down for over 24 hours. Good news is that the basement didn't go down to freezing during that period. I don't drain the water lines, just shut off the water, which fortunately is located at the basement floor level, chance of a freeze there is minimal since it's over 8 ft. below ground level.
