The ideal thermostat temperature in the winter is 68 degrees Fahrenheit when you’re at home. Energy.gov suggests that 68 degrees is a good room temperature while you’re awake at home but recommends lowering it while you’re asleep or away. According to Energy Star, you can save up to 10% a year in heating costs by lowering thermostat temperatures seven to ten degrees for eight hours a day. Therefore, while you’re away or sleeping, it is recommended to lower your thermostat to around 60 degrees for additional cost savings. If you find 68 degrees too chilly, you can gradually lower the temperature until you reach your desired comfort level. It is important to note that the temperature should not be set below 50-55 degrees to keep your appliances and pipes from freezing.
