What is the best temperature to set your thermostat in winter? A lot of folks leave the thermostat on this setting throughout the day while they’re home.
At night or when you’re out, you can turn it down to 16 to 18 degrees Celsius or 60 to 64 degrees Fahrenheit to conserve energy and save money. Knowing that range will help keep your rooms warm and your bills low.
The body below provides additional winter tips.
The Ideal Temperature
About the Perfect Temperature Most recommend 68°F (20°C) as a good goal when people are home and awake. This range enables your furnace to perform optimally without overtaxing itself or consuming copious amounts of energy while maintaining sufficient warmth for the majority of us.
Some opt for a warmer 70 to 72°F (21 to 22°C), while others are okay with 68°F or less, particularly if they use additional layers or blankets. The key is balance: keep the gap between indoor and outdoor temperatures moderate to help both comfort and efficiency.
While you sleep or are away, keeping it lower saves even more energy and money. Small adjustments can go a long way, especially when made with a programmable thermostat.
| Activity | Recommended Thermostat Setting | Time Frame |
|---|---|---|
| At Home & Awake | 68°F (20°C) | Daytime |
| Sleeping | 60–65°F (16–18°C) | Night |
| Away from Home | 55–60°F (13–16°C) | Extended Absence |
1. When Home
Maintain a consistent room temperature that suits us all. For most homes, 68°F to 72°F works well. Adjusting by 1 or 2 degrees at a time helps perfect this balance.
Blankets or warm clothes on top of this layering mean you can keep the thermostat set lower and still feel cozy. It’s an approach that saves energy without sacrificing comfort.
Monitor the outside conditions daily. If it’s warmer outside, you can lower the thermostat some. Once it begins to cool, little increases here and there can assist.
Test out the temperature and make small increments, not big swings, for best energy usage. That way, everyone remains cozy and the boiler is not overtaxed.
2. When Sleeping
Sleep experts suggest a cooler room, typically between 60 and 65 degrees, for optimal rest. Most smart thermostats take care of this transition for you, so you don’t have to remind yourself every evening.
Thicker sheets or an extra blanket allow you to keep warm without turning the heat up. Others may prefer it hotter or colder so experiment what suits each member of the household.
If you’re in a common area, aim for the center of the range and provide additional blankets as necessary. Dropping the thermostat by only eight hours can reduce annual heating bills by as much as 10%.
3. When Away
Lower the temperature or turn the thermostat down 10 to 15 degrees if you’ll be gone for a few hours or more. Nearly all programmable or smart thermostats feature a vacation mode, which maintains the house at a safe yet energy conserving temperature while you’re away.
Don’t turn the setting up and down too frequently, as this wastes additional energy. Be sure to monitor the local forecast. If a cold snap is approaching, you might want to keep the heat a little higher to prevent freezing pipes.
If not, lean toward the low setting for the greatest economy.
Personalizing Your Setting
Every home has a different dynamic when selecting the optimal winter thermostat setting. Few things impact comfort and energy usage more than tiny adjustments to your living space, who lives there, and even when you’re home. A reasonable default for most is 18°C to 22°C (64°F to 72°F), but the optimal setting varies based on more than just the weather.
Home Factors
| Factor | Impact on Thermostat Setting |
|---|---|
| Insulation Quality | Poor insulation leads to more heat loss, needing higher temp |
| Window Number/Placement | More windows, or north-facing, can let in cold |
| Sunlight Exposure | Sunlit rooms may need less heating |
| Home Orientation | South-facing rooms can be warmer naturally |
| Room Usage Patterns | Frequently used rooms may need more heat |
| Thermal Curtains | Help keep warm air in and cold out |
Direction is important. If your home has any south-facing rooms, they might be getting extra sun and warmth during the day and need less heating. North-facing rooms can feel a bit chilly and could use a warming boost.
Consider your most frequented rooms. Bedrooms could use less heat in the day but more at night. Living rooms, particularly with oversized windows or vaulted ceilings, can dissipate heat at a more rapid pace and require specific care.
Thermal curtains are a simple solution for drafty windows. They keep out cold drafts and hold warmth inside, meaning you can maintain a consistent, comfortable temperature with less effort.
Human Factors
Striking a balance for everyone’s comfort is the trick. Some people like it warmer, some cooler. We recommend setting your thermostat to the midpoint of the comfort range, roughly 18°C to 24°C (64°F to 75°F), and then making adjustments as needed.
Cooking, electronics, or general activities warm up a space, so turn it down when the oven is on or when half the neighborhood is in your house.
It’s a proven fact that if you’re physically active, you feel warmer. Therefore, if you’re working out indoors, a lower setting may be just right.
Consult with everyone in your household to discover the optimal compromise. Comfort is personal and it can take a couple of attempts to get it right.
System Factors
Your thermostat location is important. Try not to place it near sunlit areas, doors or vents for an accurate measurement. This allows the system to operate only when necessary.
Holding the setting constant all day isn’t optimal for your bills. Personalizing Your Setting Turning your thermostat down 4°C to 6°C (7°F to 10°F) during the day when you’re out or overnight saves energy without sacrificing comfort.
Keep up with your bills each month. Personalize your setting and see how little things, like thermal curtains or accounting for your daily routine, impact costs and comfort.
Eventually, you’ll discover the magic balance for your space and your budget.
Comfort vs. Cost
This comfort vs. Cost tradeoff is key when selecting the optimal winter thermostat setting. So much depends on your day-to-day activities, the climate, and how comfortable you are. Lowering the heat when you’re gone or asleep, the setback principle, is crucial for saving energy and reducing your bills.
Tools such as programmable thermostats help simplify setting different temperatures at different points in the day, giving families a convenient way to strike that nice balance of comfort and savings.
The Setback Principle
A lot of us think if we crank our thermostat up it’ll heat a room faster, but it won’t. The furnace runs at full throttle whether it’s on 55 degrees or 75. Maintaining the thermostat at 20°C (68°F) during the day is a happy medium for most folks, providing comfort and savings.
Bumping it up a degree or two when it’s necessary is a minor adjustment that won’t result in a huge jump in your energy costs. It’s more efficient to maintain a constant temperature than it is to make frequent adjustments. Drastic temperature swings make your furnace or boiler run harder, which can increase costs in the long term.
A lot of people believe that if they drop the thermostat very low when they leave the house they’ll save the most money. The real savings is in moderate changes. To illustrate, reducing the thermostat by roughly 8 degrees for a minimum of four hours while the house is unoccupied generates significant savings, but further reduction may not be feasible for all.
Knowing how these decisions affect total energy usage is crucial. Heating alone can comprise 43% of a household’s energy bill, so the little things can accumulate. Getting everyone in the household educated about these advantages goes a long way toward keeping everyone on board with an empty house that is kept cooler, resulting in better outcomes.
Debunking Myths
Adjusting the thermostat is not equal. For very cold or damp environments, 18.3°C (65°F) is potentially too cool, particularly for children, senior citizens, or individuals with specific health requirements. Some need it warmer, some are good with it cooler.
Each household should experiment with various settings, find out what is comfortable, and monitor for evidence of energy savings. Local weather plays a role. If winters are mild, a lower setting may suffice. In areas with bitter night cold, a slightly higher temperature can keep things comfortable at little additional expense.
Keeping an eye on how comfortable the indoor temperature feels as seasons shift is an easy way to be informed about when to make adjustments. Programmable thermostats simplify syncing heat with routine. For example, lowering the heat at night or when the house is deserted and then coming back to 20°C when people are stirring removes the guesswork.
It’s always handy to check back in as the season’s weather shifts, making sure the scales between comfort and cost stay at equilibrium.
Global Climate Considerations
Thermostat settings during winter are influenced by local climate, home insulation, energy usage habits, and even cultural schedules. Families and individuals across the globe contend with their own dilemmas when trying to find the right compromise between comfort, health, and expense as temperatures fall.
Thermostat adjustments, the smart use of sunlight, and energy monitoring are all practical steps that can help anyone optimize their winter heating, regardless of their location.
Mild Winters
Mild winter climates demand more flexible thermostat routines. For regions where daily temperatures vary, it’s logical to adjust your settings as you go rather than set it and forget it. Just a one or two degree drop could really impact consumption without bothering most people.
Nothing helps you keep up with these swings better than a good programmable thermostat. It can adjust the temperature on your schedule, so you don’t have to think about it constantly.
Even homes in milder zones require essential maintenance warmers and vents checked. Even minor problems, such as dirty filters or obstructed vents, can reduce efficiency and increase expenses.
Dry air is yet another villain, so including a humidifier can prevent issues like dry skin and static shocks while permitting the air to feel warmer at lower temperatures. Periodic inspections and minor adjustments add up to comfort and savings.
Moderate Winters
When confronted with a mild winter, we’re all guilty of turning our thermostats a degree or two higher, somewhere in the neighborhood of 68°F to 20°C. This position provides a nice balance of comfort and energy efficiency.
For cooler times or nighttime hours, reducing the thermostat a few degrees can conserve energy as you snooze. Certain households employ zone heating, using space heaters to heat the rooms they frequent most, avoiding heating empty rooms.
Insulation matters more during these months. Weather stripping doors and windows or simply using thicker curtains can keep warmth in and squeeze every degree of warmth possible.
With heating and cooling accounting for more than half of the average household energy bill, these miniature insulation moves really add up. Monitor your energy bills and heating system performance to ensure the strategy is functioning as anticipated.
Severe Winters
In more brutal winter climes, the thermostat becomes more of a necessity for comfort and for health. If we turn the thermostat down too low, we open ourselves to the danger of indoor cold air, which can cause respiratory issues, particularly for the elderly and children.
Humidity control counts too. Dry indoor air, typical in winter, can irritate your respiratory tract and make breathing more difficult. A humidifier not only makes the air healthier, it makes warm air feel more even.
Furnaces may undergo additional stress during extended cold snaps. Unexpected breakdowns not only throw you out of comfort but can result in costly repairs. Staying on top of maintenance and monitoring for early symptoms of stress is crucial in these times.
Expensive heating costs can strain household budgets. Keeping an eye on your bills and adjusting your thermostat even one degree can keep costs down and reduce greenhouse gas emissions, which is a win-win in the fight against climate change.
The Unseen Consequences
Your thermostat in winter is more than just selecting a number. That decision has far-reaching impacts on our health, comfort, and energy bills. When homes become too cold, we all suffer. The immunocompromised, elderly, and infants are at greater risk. Chilly indoor air can exacerbate breathing issues, cause joint pain, and even sickness.
Maintaining room temperatures between 20°C and 21°C (68°F and 70°F) safeguards against them. Lowering the temperature too low to save money can backfire. Heating systems are essentially playing catch up and working overtime, which means extra energy consumption and higher operating costs.
Health Impact
Too little heat in winter doesn’t just make people shiver. It can damage the home. Cold air allows moisture to accumulate on walls and windows, creating an environment for mold and mildew. This not only compromises the integrity but provokes allergies and respiratory issues.
Pipes are in jeopardy as well. Without consistent heat, they can freeze and explode, resulting in costly repairs. It turns out that maintaining a constant, warm temperature prevents pipes from freezing and bursting.
Keeping your thermostat tuned to a happy medium, lower at night or when you’re out, but not crazy low, keeps your consumption under control. Little 1°C or 2°C shifts make a difference. They can conserve energy without bothering anyone.
Programmable thermostats or smart devices do this easier by automatically shifting the heat. Opting for efficient heaters or upgrading would save in the long run. It decreases waste and reduces surprise breakdowns. Good insulation and annual maintenance pay off for every component of the heating system.
Home Impact
Homes heat up, room by room. Zone heating allows users to only heat the spaces they utilize most. This conserves energy and puts everyone more at ease. Smart thermostats learn from your daily habits, detecting patterns and adjusting heat with no bother.
They assist in maintaining indoor air constant, even as the weather sways. Moving warm air counts as well. Ceiling fans on low circulate hot air down from the ceiling, distributing heat.
This means the heater does not have to run as long and uses less power. Newer heating systems consume less energy and last longer. Retrofitting with these systems or additional insulation can reduce bills and make a home more resilient.
Advanced Optimization
Winter heating is more than just turning the thermostat to a specific number. Advanced optimization involves considering how heat moves in your space, how systems communicate, and how tiny tweaks in habits or tech can spark savings and comfort. The proper blend of tactics pays off regardless of climate or home design.
Zone Heating
Zone heating allows you to divide your home into sections, enabling you to heat only the areas you utilize the most. It is great for big homes or locations with rooms that sit empty most of the day. Thermostatic radiator valves are easy to retrofit onto many radiators. They open or close as required, maintaining each room at the ideal temperature without heating the entire house. This eliminates waste and can be tuned to your requirements.
Installing zone heating may be more expensive initially, but frequently pays dividends in the long run. Savings come from not heating unoccupied rooms, and it’s just nice and cozy with less hot or cold spots.
Radiant floor heating is another method to zone. It makes floors cozy warm, which is wonderful on the feet and radiates heat throughout. Though radiant heating is optimal for new construction or large-scale remodels, it can be installed in smaller zones for additional comfort in cold areas like bathrooms or entryways.
Smart Thermostats
Smart thermostats are a good starting point. They allow you to schedule settings for various times of day, such as reducing the heat while you’re asleep or away from home. High efficiency ENERGY STAR rated models, SEER2, AFUE, or HSPF2 rated, can increase system efficiency by as much as 15 percent compared to older, less efficient units.
Smart thermostats try to learn your habits and adjust accordingly. They can monitor your comings and goings or even memorize your preferences. They collaborate with apps to enable temperature adjustments remotely.
Others monitor your energy consumption and highlight where you can conserve more. Smart thermostats can connect to other smart home devices for seamless management.
Air Circulation
Simply circulating warm air keeps rooms more even and reduces cold spots. Ceiling fans set to turn clockwise in winter push warm air down and can make rooms feel warmer without turning up the heat. Placement is important as well. Move couches and tables away from vents so air circulates nicely.
Little things, like clearing clutter away from heaters, can make a huge impact. Air purifiers do as well. They circulate fresh air, which means a lot when windows stay shut in winter.
Long-Term Habits
Hitting the optimal point with your thermostat is about more than choosing a number. Set it to 20°C (68°F) during the day for a nice balance of comfort and savings. Drop it by 3 to 5 °C (7 to 10 °F) at night or when you’re out for even more savings, up to 10% a year.
Since no two homes are the same, play around until you discover what works. Stay ahead of the curve as the seasons turn. It’s all about location, location, location. Place your thermostat in a location that is not directly exposed to sunlight, away from drafts or vents, and away from your doors and windows.
Conclusion
Determining the optimum thermostat setting for winter requires focused reflection and some experimentation. Most homes adhere to 20°C, which offers a nice blend of comfort and savings. Minor adjustments, such as turning the heat down while you’re asleep, can save significantly on bills and still leave you cozy. Your local weather, house type, and who you live with all factor in. Make sure your space is well-sealed and draft-free to hold heat in. Smart thermostats can help, but old school fixes work as well. Make a few adjustments, see how it feels, and monitor your bill.
