Home heating myths

Try having a night away from home each week or on a saturday--go enjoy someone elses heat, such as the library or community center. But, if you are away from home less than 4 hours, you spend more energy reheating your house if you turn your heat down and back up again. Don't turn your heat too low when you are gone. your furnace will have to work harder to catch back up

Well this is false according to AC doctor
A common misconception associated with thermostats is that a furnace works harder than normal to warm the space back to a comfortable temperature after the thermostat has been set back, resulting in little or no savings. This misconception has been dispelled by years of research and numerous studies. The fuel required to reheat a building to a comfortable temperature is roughly equal to the fuel saved as the building drops to the lower temperature. You save fuel between the time that the temperature stabilizes at the lower level and the next time heat is needed. So, the longer your house remains at the lower temperature, the more energy you save.

What is the recommendation a programmable thermostat. We have one! Since I am home usually 24 hrs a day (remember I am a work at home mom) I keep the heat at 66 degrees a day.

You can also drop the thermostat at night to 55 or 50 degrees, and use the savings to get some nice down comforters. Have it turn back up to 60 in the morning so you don't freeze in your pajamas on the way to the shower! I find having a cold bedroom gives a pretty good nights sleep.
