I'm not exactly an expert on home heating myself--it's not that we don't get cold; we had about three consecutive weeks of sub-zero temperatures so far this winter, and Capitol Lake froze most of the way over. I just don't turn the heater on, preferring to curl up under blankets than pay the extra electricity. However, my understanding is that you'll save far more by leaving it on very low during the day than it costs to get it up to your preferred temperature--somewhere in the high sixties or low seventies?
