What Temperature Should I Set My Thermostat in Winter?

What Temperature Should I Set My Thermostat in Winter? This is a very common question that people want to know for a variety of reasons. It’s also not as straightforward of an answer as you might expect as their are many variables that factor into the ideal thermostat temperature during winter. But, we aim to explore all of the various ways to answer this important question.

Programmable Thermostats

One of the things that I highly recommend is investing in an Energy Star  programmable thermostat like the Nest Learning Thermostat, the ecobee4 Smart Thermostat (with Built-In Alexa), Emerson Sensi (1F87U-42WF), or the Honeywell (RTH9585WF1004) (WiFi). We’ll discuss these later in the article, but it’s important to note that if you don’t have a programmable thermostat, where you can set the temperature for every day of the week, for any time period you want (IE. Day and night), then you really should invest in one now.

This will make your life much easier. Let’s be honest, having to manually set the thermostat every day is not practical. I know, because when I was growing up, this is how my parents set the thermostat in the home.

Unfortunately, many people who own programmable thermostats don’t even know how to use them correctly, as written about in this article by the Washington Post.

VIDEO | How to Make Your Home More Energy Efficient for Winter

The average homeowner spends over $2,000 a year on energy bills — more than 50% of that goes to heating and cooling. You can save at least $180 a year by setting your programmable thermostat in an efficient manner. (Learn More)

What Temperature Should I Set My Thermostat in Winter?

The easy answer to the question is that you should set the thermostat to whatever temperature is comfortable for you, which might range between 68°F (20° C) to 72°F (22° C). Body temperature varies among people so ultimately it will depend on your average body temperature and also if you are someone who like to wear a sweatshirt around the house or not.

Personally, I wear light pajamas’s and a t-shirt around my condo and I live alone, so for me the ideal temperature is around 74° (23.3°C). But that’s me. If you live alone, it’s easy to figure this out. I would recommend starting at 67°F (19.4° C) and see how that feels. If it’s too cold, raise it up one degree at a time, and stop when you feel comfortable.

At night, I drop my thermostat to 68°F (20° C). In general, I prefer my home to be on the warm side. And since I live alone and pay my own heating bills, I can set it the way I want.  I will admit that heating a residential house is far more costly than heating a condo so if you want to save money, then it really does make sense to be smarter and more strategic with how you heat your home in the winter.

Now, for most people who have a family and have to deal with finding the right temperature for more than one person, in a variety of age groups, you know that this quickly can become a heated issue (pun intended). Everyone seems to have an opinion on the temperature. There’s a big range between kids, middle-aged people and the elderly, and everybody seems to want something different. So, how do you find the right temperature for your thermostat in winter when there are many people living in your home?

✓ Fact : Every 8°F (4.5°C) you lower your temperature saves you about 10% on your energy bill, and consequently, increasing your thermostat by 8°F (4.5°C) higher increases your energy bill by about 10 percent.

Recommended Thermostat Temperatures in Winter

Ideal thermostat temperature — Daytime —  When People Are Home

I recommend a setting your thermostat to 68°F (20°C) during the day, if people are at home. This is generally a comfortable temperature for most people who wear normal clothes, like pants or pajama bottoms and a t-shirt. If someone finds it too cold then they can easily use a blanket or have them wear thicker socks around the house. You’ll be amazed at what a warm pair of socks will do for your overall comfort level. It truly does make a big difference.

Ideal thermostat temperature — Nighttime —  When People Are Sleeping

I recommend a setting your thermostat to 64.4° F (18° C). It makes sense to lower the thermostat temperature since everyone will be in bed and wrapped their bed sheets. To save money, you really should drop the temperature down at least 2°C and perhaps go as low as 3°C and see what the response is from everyone in the house. I’m sure they won’t notice.

If there’s one person in the house that finds it cold at night, rather than increase the temperature for the entire house then buy them a small space heater for their bedroom. This is much cheaper than heating the entire house to please one person.

Ideal thermostat temperature —  When Nobody is Home

When nobody is home there’s no need to have a warm home. So, the best thermostat temperature during the day when people are gone is 62°F (17°C). This is also the perfect temperature to prevent your pipes from freezing, which a lot of people don’t think about.

I live in a condo and this is also the minimum temperature set by the strata to prevent the pipes from freezing. So, when the house is empty because everyone is at work or at school make sure you set your thermostat to 62°F (17°C). Even when you’re on vacation this is the ideal temperature for your thermostat in winter.

Programmable Thermostats

If you don’t have a programmable thermostat already then you need to buy one. More specifically, you need to buy an Energy Star certified programmable thermostat which allows you to get a rebate depending on where you live. Visit the Energy Star site and scroll down a little, where you’ll find a place to enter your zip code  to find out which rebate you are eligible for, like the image below.

A programmable thermostat will allow you set the thermostat temperature for every day of the week. Each day can be different so you can fully customize the thermostat to your liking. Some  Energy Star thermostat’s like the Orbit 83521, already have been programmed with Energy Star settings to save you money right from the beginning. But, nowadays, all of the thermostat’s we recommend are easy to program.

When I was growing up technology was primitive and difficult to use. Three out of the four thermostats we recommend have an app that allow you to quickly and easily program it. It’s important to learn how to use your thermostat by reading the manual thoroughly. There’s no point in investing in a high-quality thermostat with plenty of energy saving features if you’re not going to learn how to use them. So, don’t be stubborn. Spend a little time to get acquainted with your new thermostat. In the long run it will save you thousands of dollars. Set it and forget it.
