Many devices in your home rely on a thermostat to tell them when to run and when to go into standby mode. And while the best thermostats do provide ultimate control over the devices’ temperatures, knowing the best thermostat settings for each is important. After all, if you program them to be too cold or too hot, you’ll be pouring money down the drain.
Knowing the optimal settings for each device can help you maintain comfort, ensure safety, and save money on energy bills. In this comprehensive guide, we’ll explore the best thermostat settings for different appliances and situations, helping you strike the perfect balance between comfort and efficiency.
Understanding the Importance of Proper Thermostat Settings
According to the U. S. Department of Energy, you can save approximately 10% on your heating and cooling costs by adjusting your thermostat 7-10 degrees for 8 hours a day. This simple change can lead to significant savings over time while still keeping your home comfortable.
Beyond energy savings, correct thermostat settings also play a vital role in preserving food safety in refrigerators and freezers, preventing scalding from water heaters, and maintaining a healthy indoor environment. By understanding and implementing the right settings for each device, you can optimize your home’s efficiency and safety.
Optimal HVAC Thermostat Settings for Year-Round Comfort
Your home’s heating, ventilation, and air conditioning (HVAC) system relies on thermostat settings to maintain a comfortable indoor temperature throughout the year. Let’s explore the ideal settings for both summer and winter months, as well as some energy-saving tips.
Your home relies on a thermostat to control the temperature within its four walls, and it’s this thermostat with which homeowners are most familiar. In the summer, we’ll often set it low in the evening and higher during the day, if the house is unoccupied. In the winter, people often set it higher in the evening but allow it to drop a few degrees during the day to save energy. But, what’s the ideal setting for each of these seasons?
Best Thermostat Settings for Summer
During the summer, a daytime temperature setting of around 78°F should keep you comfortable without excessive energy consumption. Most nights are a little cooler, so it’s likely fine to leave the thermostat set to 78°F all summer, day and night. If your climate is hotter at night, consider bumping the temperature up a few degrees to save money, but only if you’re able to sleep in such conditions.
Don’t forget that insulating the home, sealing cracks and gaps, and installing new weather stripping around doors can help reduce the amount of heat and cooling loss. This alone may allow you to lower the thermostat a degree or two in winter without feeling any less comfortable.
Ideal Thermostat Settings for Winter
When the temperature drops, it’s tempting to crank up the heat. However, maintaining a slightly lower temperature can lead to significant energy savings without sacrificing comfort. The Department of Energy suggests setting your thermostat to 68°F (20°C) when you’re awake and at home during winter months.
At night or when you’re away, you can lower the temperature even further. A setting of 62-65°F (17-18°C) while you sleep can help you save energy and may even promote better sleep, as most people sleep best in slightly cooler temperatures.
Energy-Saving Tips for HVAC Thermostat Use
To maximize your energy savings, consider these additional tips:
- Use a programmable or smart thermostat to automate temperature changes.
- Avoid drastic temperature changes, as this can cause your system to work harder.
- Keep your thermostat away from heat sources or drafts that could affect its readings.
- Seal air leaks and improve insulation to maintain desired temperatures more efficiently.
- Regular HVAC maintenance can help your system run more efficiently at any temperature setting.
Recommended Thermostat Settings for Refrigerators
Your refrigerator (and freezer, most likely) utilize thermostat settings to tell them when to generate cold temperatures. While it’s rare that either of these appliances will provide an exact temperature to set the thermostat to, there are still ideal settings.
When it comes to keeping your food fresh, 37°F is ideal. This temperature will keep food fresh, prevent bacteria growth, and keep ice from forming. When it comes to freezers, 0°F is ideal.
But fridges and freezers sometimes only have five or so settings, none of them 37°F or 0°F. In this case, the best way to determine which setting is appropriate is to start at the lowest temperature setting and place a thermometer inside the refrigerator or freezer for a day to two. If it’s too cold after a day or two, adjust the setting up a notch and repeat the process until both appliances maintain the appropriate temperature.
Recommended Thermostat Settings for Water Heaters
Water Heater Thermostat Settings: Balancing Safety and Efficiency
Water heater thermostat settings are crucial for both safety and energy efficiency. Let’s explore the recommended settings and how to adjust your water heater thermostat.
Understanding Water Heater Temperature Recommendations
There’s some debate about the ideal water heater temperature setting. The Occupational Safety and Health Administration (OSHA) recommends 140°F (60°C), which is the default setting for many water heaters. This temperature effectively kills harmful bacteria but poses a scalding risk.
On the other hand, the Environmental Protection Agency (EPA) suggests setting your water heater to 120°F (49°C) to save energy. This lower temperature still provides hot water for most household needs while reducing the risk of scalding.
For most households, a setting of 120°F (49°C) strikes a good balance between safety, energy efficiency, and effectiveness. However, if you have a suppressed immune system or respiratory disease, you may want to keep your water heater set to 140°F (60°C) to kill potentially harmful bacteria.
How To Adjust Your Water Heater Thermostat
To adjust your water heater thermostat:
- Locate the thermostat(s) on your water heater. Electric heaters often have two, while gas heaters typically have one.
- Turn off the power to electric water heaters or set gas heaters to “pilot. “
- Remove the thermostat cover(s) to access the adjustment dial.
- Use a flathead screwdriver to adjust the temperature to your desired setting.
- Replace the cover(s) and restore power or turn the gas back on.
- Wait a few hours, then test the water temperature at a faucet using a thermometer.
Special Considerations for Thermostat Settings
Different situations and populations may require special thermostat considerations. Let’s explore some of these scenarios.
Thermostat Settings for Seniors and Children
Seniors and young children may be more sensitive to temperature changes and require different thermostat settings. For seniors, a slightly warmer environment is often more comfortable. Consider setting the thermostat between 70-72°F (21-22°C) during waking hours.
For homes with infants or young children, maintain a consistent temperature between 68-72°F (20-22°C) to ensure their comfort and safety.
Adjusting Settings for Vacation Homes and Unoccupied Spaces
For vacation homes or spaces that will be unoccupied for extended periods, you can adjust your thermostat to save energy while still protecting your home. In winter, set the thermostat no lower than 55°F (13°C) to prevent pipes from freezing. In summer, you can set the temperature higher, around 85-90°F (29-32°C), to prevent humidity buildup and mold growth.
