The insulation in my apartment sucks. What's nice is that I can control the bedroom and the living area separately. I leave the bedroom heating off and keep the door close until just before I want to take a shower, then turn it up to 70, then back down to 60 before I go to bed. I do the same thing with the living room--it gets turned off when I leave for the day, then I turn it up to 70 for a bit and back down to 60. Then I turn it off at night.
