The ideal thermostat temperature in the winter is between 68 and 72 degrees Fahrenheit when youre 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. Lowering the temperature by around five degrees while you’re away from home for more than four hours in the winter can help reduce your heating bill. 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. If you have young children or elderly family members living with you, it’s important to keep them warm and comfortable. You should also consider what activities you’ll be doing in your home and how well-insulated it is. Gradually lowering the temperature by one to two degrees can help you adjust to the indoor temperature. Layering clothing is also a way to stay warm in the cooler house temperature.
