Best Temperature to Set Your Thermostat in Winter to Save Money

A few simple thermostat adjustments can make a difference in your energy bills without leaving you shivering under three blankets all winter.

In this guide, you’ll learn the ideal temperature to set your thermostat in winter to save money. Explore the factors that affect your best thermostat setting and practical thermostat tips to keep your home comfortable without the painful utility bills.

What Is the Best Temperature to Set Your Thermostat in Winter?

The short answer is 20°C (68°F). That’s the benchmark most energy experts point to for homeowners who want to balance home comfort with lower heating costs. It’s warm enough to feel comfortable. Cool enough to keep your heating system from working overtime.

According to Energy.gov, this thermostat setting strikes a balance between comfort and energy savings. Your heating and air conditioning system runs efficiently, and your energy bills don’t spiral out of control.

That said, 20°C isn’t a universal rule. Your ideal or comfortable temperature depends on your household. Who lives there, how your home is built, and how efficient your heating system is all play a role.

What To Consider When Setting Your Thermostat

The right home temperature isn’t the same for every household. Before settling on a winter thermostat setting, take a look at who and what shares your space.

Seniors and Health Conditions

Older adults feel the cold more sharply. As the body ages, it becomes less efficient at holding heat. For seniors, cooler temperatures are uncomfortable and can be a health risk. The World Health Organization recommends indoor temperatures of at least 20°C (68°F) for older adults.

Warmer temperatures are recommended for those with circulatory conditions or other health concerns. If someone in your home fits this description, factor that into your thermostat setting before defaulting to the energy-saving benchmark.

Infants and Young Children

Babies can’t regulate their body temperature as well as adults can. A home that feels fine to you might be too cold for a newborn. Most pediatric health guidelines suggest keeping a baby’s room between 20°C and 22°C (68°F to 72°F). Pay attention to how your child sleeps and behaves. That’s often the clearest signal that the home temperature needs adjusting.

Pets

Different animals have different needs. A short-haired dog or a cat that stays indoors all day needs a warmer environment than you might expect. Dropping your home temperature too low while you’re out can cause real discomfort, or worse, for pets left behind. Check the specific needs of your animal before lowering the heat during away hours.

Pipes

This one catches homeowners off guard. When outdoor temperatures drop sharply, and your indoor heat is set too low, the gap between inside and outside creates conditions where pipes can freeze. This is especially true for pipes along exterior walls or in poorly insulated areas of your home. A frozen pipe is inconvenient and expensive. Keeping your home at a minimum of 16°C (60°F), even when you’re away, helps protect against heat loss and the damage that follows.

Temperature Swings

Frequent, significant temperature changes put strain on your heating system. Cranking the heat up by several degrees to warm a cold house quickly doesn’t heat the space faster; it just runs your HVAC system harder and longer. That extra energy use shows up on your electric bill.

A study published by the American Council for an Energy-Efficient Economy found that consistent, moderate temperature settings outperform erratic adjustments in both energy efficiency and cost. Keeping your home temperature steady with gradual shifts rather than dramatic ones is better for your heating system and your energy bills.

The 7 to 12 percent savings often tied to nighttime temperature adjustments assume those changes are moderate and consistent. Dropping 3°C to 4°C (about 7 degrees Fahrenheit) overnight is effective. Dropping 10°C and then blasting warm air in the morning cancels out the benefit and adds unnecessary wear to your system.

Best Thermostat Tips to Save Money All Winter

Small adjustments add up fast when it comes to heating costs. These tips are simple, low-effort, and they work. Here’s where to start.

Lower the Heat While Sleeping or Away

This is one of the easiest ways to cut your heating bill. The recommended thermostat setting shifts when you leave the house or go to bed. Drop your thermostat setting by 3°C to 6°C (7°F to 10°F) while you sleep or leave the house.

According to the Department of Energy, that adjustment alone can trim your energy costs by up to 10 percent annually. On a $200 monthly heating bill, that’s $20 back in your pocket, every month.

Set a consistent schedule. Drop the temperature at the same time each night. Bring it back before you wake. Your home comfort stays intact, and your energy bills shrink quietly in the background.

Dress Warmer Before Reaching for the Dial

Reach for a sweater before touching the thermostat. It sounds simple because it is. A warmer layer or an extra blanket keeps you comfortable at a lower home temperature. That means your heating system runs less, and energy use drops

Use Zone Heating

Heating every room equally wastes energy. If you spend most of your time in two or three rooms, focus the heat there. Close the vents in unused rooms. Use a space heater selectively in the rooms where you spend the most time.

This approach, called zone heating, can reduce your overall heating costs without touching your main thermostat setting.

Ceiling fans can help here, too. Set them to run clockwise at a low speed in winter. This pushes warm air that rises to the ceiling back down into the room. It costs almost nothing to run and makes a noticeable difference in how warm a room feels.

Check Your Thermostat Placement

When your thermostat sits, it matters more than most homeowners realize. A thermostat on an interior wall away from windows and doors gives the most accurate reading.

Put it near a drafty window, and it reads cold, triggering your heating system to run longer than necessary. Place it near a heat source such as a lamp, a vent, or direct sunlight, and it reads warm; shutting off the heat before the rest of your home is comfortable.

If your thermostat sits in a poor location, it could be inflating your heating and cooling bills without you ever knowing. Check its placement. Ensure it sits on an interior wall, away from anything that could skew its temperature reading.

Pay attention to how your home heats, where the heat goes, and when your system runs. That awareness alone puts you ahead of most homeowners when it comes to managing winter energy costs.

How to Handle a Heating Repair You Didn’t Budget For

A broken furnace or failed thermostat in the middle of a Canadian winter is uncomfortable and urgent. Repairs like these can’t wait. And the cooling costs that come with them rarely show up at a convenient time. Here’s what to do when a heating repair catches you off guard.

Check Your Home Insurance

Some home insurance policies cover sudden mechanical failures. Before paying out of pocket, call your provider and ask. It takes 10 minutes and could save you hundreds of dollars. Know what your policy covers before assuming you’re on your own.

Look into a Payment Plan

Many HVAC repair companies offer payment plans for larger jobs. Ask upfront. A $1,200 furnace repair spread over a few months is far easier to manage than a lump-sum payment due immediately. Most companies would rather work with you than lose the job.

Tap Your Emergency Fund

This is exactly what an emergency fund exists for. If you have one, use it without guilt. That’s the point of it. Replenish it once the repair is paid and move on.

Consider a Short-Term Loan

If your emergency fund isn’t there yet and a payment plan isn’t available, a short-term payday loan can cover the gap. It gets the repair done fast, before the cold does more damage, and lets you repay on your next paycheque. Use it for the repair. Have a repayment plan ready before you borrow.
