I do the same. My heating cycle is 69F @ 4:30 am to heat the house by the time we get up about 5:30. That holds until 7 am when it goes back to 67F for the day. At 4:30 PM we heat to 72 F until 5:00 PM. (5 pm is when my electricity switches to peak rate*). We hold 69F to 7 pm and let the temp drop to 67F for the night. (It takes hours for the temp to actually fall down to 67F) (That is the schedule Mon - Thursday when we are both at work)
Rates are: $0.08 from 9pm - 7am / $0.16 from 7am - 5 pm / $0.41 from 5 pm - 9pm

There is a HUGE difference in efficiency. A furnace is 80 - 95% efficient. Heat pumps are 250% - 300% efficient.
