Why Thermostat Settings Matter in Cold Weather

Heating accounts for a significant portion of energy use in most homes, especially during colder months. The right thermostat setting can help reduce energy waste and keep your heating system running smoothly, so you’ll have a warmer home and lower bills. Let’s dive into the ideal temperature settings for cold weather days, nights, and when you’re away.


Best Heater Thermostat Settings

1. During the Day: 68–70°F

The U.S. Department of Energy recommends setting your thermostat to 6870°F during the day when you're at home and awake. This temperature offers a good balance between comfort and efficiency for most people. Adjusting to a slightly cooler home can help you avoid excessive heating costs.


Quick Tip: If 68°F feels chilly, add layers like cozy sweaters and warm socks, which may make a lower temperature feel more comfortable without raising the thermostat.


2. While You’re Away: 60–62°F

When you’re not home, lower your thermostat to 60–62°F. This drop can save energy while keeping the house warm enough to prevent issues like frozen pipes in especially cold climates. With a programmable or smart thermostat, you can easily set schedules to lower and raise the temperature based on your routine automatically, so you won’t have to remember to adjust it each time you leave.


Pet Tip: Pets are just as prone to cold-related complications as humans. To keep your furry friends comfortable and safe while you're away, consider setting your thermostat to 68–70°F. If your pet is more tolerant of the cold, you can turn down the thermostat by a few degrees, keep your pet in the warmest room in your house—usually the kitchen or a bedroom—and provide warm bedding.


3. At Night: 62–65°F

While sleeping, reduce the temperature to 62–65°F. Research shows that people sleep better in cooler environments, and lowering the thermostat at night can lead to even more energy savings. With extra blankets and cozy pajamas, many people find this setting comfortable in winter.


Pro Tip: If you have a smart thermostat, consider increasing the heat before you wake up so your home is comfortably warm in the morning without wasting energy overnight.


Considerations for Homes with Heat Pumps

If using a heat pump, be cautious when setting back the thermostat, as frequent temperature changes can make heat pumps less efficient. Instead, set your thermostat to a consistent, energy-efficient temperature and leave it there. Many modern heat pumps have “smart” or “adaptive” modes that learn your schedule and manage temperature shifts efficiently.


Using Smart Thermostats for Better Control

Smart thermostats can automatically optimize your heating schedule to save energy. They learn your habits and adjust temperatures based on when you’re home, away, or asleep, maximizing comfort and minimizing energy usage. Some models even offer remote access, so you can make adjustments while you’re away, ensuring you always come home to a cozy environment.


Energy-Saving Tips for Winter Heating

  • Close Curtains at Night: Windows can be a major source of heat loss. Closing curtains or blinds in the evening adds an extra layer of insulation.

  • Let in the Sun: Open curtains on sunny days to let in natural warmth, especially in south-facing rooms.

  • Seal Air Leaks: Use weatherstripping or caulk around doors and windows to keep cold air out and warm air in.

  • Use Ceiling Fans Wisely: Many ceiling fans have a “reverse” setting to push warm air downward, improving circulation and comfort in winter.


What About Homes with Elderly Residents or Babies?

While 68°F may work for you, certain groups, like babies and elderly residents, may need a slightly warmer environment. Aim for 70°F if your family members feel the cold more. Just remember that each additional degree can increase energy use by about 3%, so adjust with energy efficiency in mind.


Summary: The Best Cold Weather Thermostat Settings

To save energy and stay warm when it's chilly outside, aim for:

  • 68–70°F during the day when you’re home

  • 60–62°F when you’re away

  • 62–65°F at night


With the right thermostat settings and a few simple adjustments, you can stay comfortable and save money on heating costs all winter long.
