"Optimal Timing for Fall Heating: When to Turn on the Heat"
The ideal time to turn on the heat in the fall depends on factors such as the location and insulation of your house, as well as your local climate. However, it is recommended to keep the indoor temperature above 64 degrees Fahrenheit for the health of individuals with respiratory or cardiovascular conditions, as lower temperatures may cause issues. For healthy individuals under 65, lower temperatures are generally not a health risk as long as they are active and can use clothing or heating devices to stay warm. If you have a programmable thermostat, Energy Star suggests setting it to turn on the heat when the temperature drops to 70 degrees in the morning or evening, with an eight-degree setback during the day and at night for energy efficiency.
