How do I use my thermostat in heating a home ?

when to set the thermostat to the desired temmperature in winterHow do I use my thermostat in heating a home ?If it's a programmable thermostat you can set it any time you want to.If it's an older one you can too.Look at when you are in the house and when you're not. When you're out you don't have to use as much heat as when you're there. It also helps if you wear warmer clothes when you're home so you don't feel as cold. At night turn it down. I have mine set for 70 degrees for about 10 hrs a day and then it goes to 66 at night and during my off-peak hours.
