Bottom line. Overall, keeping your heat set to 68°F to 70°F during the day, and 7°F to 10°F lower when you're not home, is the best way to save on heating costs.
Nationwide average: 60 to 75 degrees Fahrenheit
The ideal temperature in the United States during winter ranges between 60 to 75 degrees Fahrenheit. This is an average temperature to set your thermostat settings based on varying climates nationwide.
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 your thermostat 7-10 degrees for eight hours a day can reduce your annual heating expenses by as much as 10 percent.
8 am – 4 pm: While you're at work or out and about, set your thermostat to a lower temperature, such as 18-20°C. This will help you save money on your heating bills and also keep your home above freezing.
According to the DOE, setting your thermostat back 7°F to 10°F for 8 hours a day from its normal setting can help you save up to 10% in energy costs. This means keeping your thermostat around 78°F in the summer (higher when you're asleep or away) or around 68°F to 70°F in the winter (lower when you're asleep or away).
According to the experts at the Energy Saving Trust, the idea that you can save money by keeping your central heating permanently on low is a myth. This is mainly because of problems with home insulation. If your house is old or draughty, for example, heat will be leaking out through windows and doors.
You can easily save energy in the winter by setting the thermostat to around 68°F to 70°F while you're awake and setting it lower while you're asleep or away from home.
The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees Fahrenheit for healthy people. The minimum temperature should be kept above 68 degrees Fahrenheit to protect the very young, the elderly, or people with health problems. Watch out for signs of hypothermia.
A range of 68-70 is the best setting in winter if you want to save money because your furnace or heat pump doesn't have to work as hard as it does to reach a higher set temperature.
Natural gas furnace heating cost
Natural gas is likely the cheapest way to heat your home, provided you have natural gas in your area. A natural gas furnace costs $30 to $60 per month to run, which makes it 30% to 85% cheaper to run than an oil, electric, or propane furnace.
There may be drafts and pockets of colder air near the floor; The walls are colder and don't emit the usual amount of infrared radiation, so you lose heat due to your body emitting more IR than it receives; You may spend more time indoors and hence have less physical activity, so your body generates less heat.
General recommendations for winter thermostat settings: If someone is at home in the daytime, 72° F (22° C) is a good start, but aim for 68° F (20° C). If everyone is away from home in the daytime or you're asleep at night, we feel 66° F (19° C) to 62° F (17° C) is best.
Keeping your home at a constant temperature generally means that your HVAC system will run constantly to meet it. This means that your furnace or air conditioner may run when you're asleep, at work, or out of the house. This wastes more energy than the minimal amount that you might save by having it constantly run.
The World Health Organization (WHO) recommends setting your thermostat no lower than 64 degrees (F) in the Winter months while people are in the home. If there are infants or elderly individuals, they recommend keeping the temperature at 70 degrees at a minimum.
If you're cold even though your thermostat indicates you shouldn't be, your furnace likely isn't the problem. In most cases, it's working just fine. It's your home that needs attention. Lack of insulation, severe air leakage, and/or unbalanced ductwork are frequently to blame.
Cold homes contribute to excess winter mortality and morbidity. Most of the health burden can be attributed to both respiratory and cardiovascular disease, especially for older people. In children, the excess winter health burden is mostly due to respiratory disease.
Minimum Heat Setting for an Empty House
The minimum temperature setting is between 55 and 60 degrees. Setting the indoor temperature below 55 degrees in the winter could cause problems.
68 to 72 degrees is a temperature range that is not too warm or cool, and is sufficient enough to warm up the home just enough so that everyone is comfortable regardless of the type of clothing they have on.
Generally speaking, the most efficient temperature for your thermostat is between 18°C and 20°C. If you set the thermostat any higher, then you'll find that your property is very warm and it may be unsafe for babies and people with heart conditions.
You should set your thermostat to the lowest comfortable temperature for your needs. For most people, this is between 18°C and 21°C.
Thermostat settings play a pivotal role in managing your heating system's efficiency. It's a common misconception that leaving your heating on at a constant temperature is more energy-efficient than turning it on and off. Does turning the heat on and off raise the bill each month? The answer is no.
Yes, open doors are generally better in winter to maintain a consistent temperature. They allow your heating system to distribute warm air evenly across rooms, improving comfort and efficiency while preventing energy waste.
