The ideal thermostat temperature in the winter is 68 degrees Fahrenheit when youre at home. This temperature gives you a nice balance between comfort and energy efficiency. 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 youre away or sleeping, it is recommended to lower your thermostat to around 60 degrees for additional cost savings. However, it is important to consider your familys comfort level and adjust the temperature gradually to avoid discomfort. If you have young children or elderly family members living with you, it’s important to keep them warm and comfortable. You can also use a smart programmable thermostat to automatically lower the temperature when you’re not home and give you greater control over your home’s heating system.
