What Temperature Do You Set Your Thermostat?
By Patrick on Jan 11, 2008 in Energy and Money, Frugal Living
My coworker came into work the other day complaining about a $225 heating bill. That is about 3 times as much as my wife and I normally pay! We had a couple straight weeks below freezing, so the high amount wasn’t very surprising. But it still seemed higher than it should be. When I asked him about it, he said it was only about $50 higher than normal.
A few questions later I was able to determine that his house is roughly the same square footage as ours, we have the same gas company, and the reason why his bill is so much higher than ours - he leaves his thermostat set at 75 degrees 24 hours a day, 7 days a week, regardless of whether or not someone is home. I could understand this if he were married and had an infant at home at all hours of the day, but he is single and has two dogs.
This is a brief excerpt of our conversation:
“Why don’t you turn the thermostat down when you go to work,” I asked?
“Because I feel bad if my dogs get cold,” was his reply.
My thought was - “I feel bad paying $200 per month!” Of course, I didn’t say that out loud!
Use a programmable thermostat to save money
I gave him some information about how he could save at least 20% on his monthly utility bill by installing and correctly using a programmable thermostat
The US Department of Energy estimates you can save10% on your heating bill by rolling back your thermostart 10-15% for just 8 hours! Since he is gone 10 hours a day for work and sleeping 6-8 hours of the day, he really only needs to keep his house warm enough for his standards a few hours per day. Reducing his average temperature by 10% for a total of 16 hours per day could save him 20% on his heating bill! As for the dogs, I think they will be fine in a cooler environment.
What temperature should you set? I recommended he set the thermostat to automatically come on to 70 when he comes home from work, go down to 65 when he goes to sleep, warm the house before he awakens, and go back down to the low 60’s when he leaves for work. Your thermostat will automatically regulates your home’s temperature and you never think about it again - or at least until the seasons change.
These recommendations are sensible, and not too drastic of a change for most people to deal with. Again, I think his dogs will be fine. My wife and I actually keep our temperatures a little cooler during the winter, at 68 when we are home, and 55 when we are away. But, it is easier to make transitional changes instead of drastic changes, so I recommended the middle ground for my friend. In the summer we usually set the thermostat at 76-78 when we are at home.
What is too hot or too cool for a thermostat setting? In my opinion, if you can walk around your house in shorts and a t-shirt in the winter, you probably have your heater set too high. Conversely, in the summer, if you need to wear pants and a sweatshirt to stay warm enough to be comfortable, you probably have your AC turned set too low. In both cases, you are probably wasting a lot of money.

My wife and I leave our thermostat at 50°-52° during the day. In the evening, we might turn it up to 58° or so, but we turn it back down before we go to bed. We never bother to turn it up in the morning.
We could get a programmable one, but we’re pretty good about remembering to turn it down and between our schedules being so irregular and our being comfortable with just throwing on an extra layer of clothes or a blanket we don’t really need the temperature up every night.
It’s cold, but that’s what we get for living in Maine in the winter.
That being said, our thermostat is in our kitchen near an open basement door and our front door, so the rest of the house tends to be a little warmer than that. We also have a heated mattress pad that we turn on for 10 minutes or so before we go to bed, and a space heater that we use in the bathroom when we shower at home.

Since my wife it as home during the day, we can’t roll it back for that period. However, we do use a programmable thermostat and set it pretty low at night since each one of us enjoys a cooler home for sleeping.
It does save money.

I keep mine set around 60 during the day, 65 while I’m at home. Its a constant war between me and the roommate that wants to live in a 70 degree environment year round!

Our thermostat is set to 56F round the clock (it’s one of those manual ones), but given the outside temperature (daytime max around 52F) it pretty much never switches on. DW likes to suffer, so she heats the room she’s working in with a space heater and consequently freezes whenever she moves into another room. I’m getting used to the cold and dropping more and more layers. It doesn’t feel cold anymore. Even better, stepping outside doesn’t feel cold either.

We both like it much cooler for sleeping, so we don’t mind dropping the temp down to the mid-fifties.

Since most of the civilized world uses metric, we set ours at 21C when we are home, and then 17C when we are at work and 18C at night. That’s about 70C, 62C, and 64C.

I used to be an aircraft mechanic, and I HATED trying to remember which fraction was bigger or smaller, especially when we used multiple fittings, connectors, head sizes, etc. - many of which went down to the 64th of an inch.
Why not just use something simple like the decimal system? Unfortunately, industry is set the way it is, and it would cost hundreds of billions of dollars to change things now.

Ours is 18C when we’re home and awake. (weekends, evenings) 15C at night and when we’re not home. The cats have fur, they cope! We keep blankets all over the place and it’s not so bad. Slippers and sweaters are a must.

Wow and I thought we kept it cold at 62 or so. The house is really badly ventilated, so I personally think it’s pointless to turn the heat on at all. But I can’t convince my roommates of that… I have a built-in space heater in my room (as does one other roommate). It’s the 3rd one who keeps trying to turn the heat up to 68.
In the summer, it’s ridiculously cold in here, I think. Again, the same two of us keep turning it up, while the 3rd one turns it down…

Remind him that his dogs have a fur coat.
I don’t know the actual temperature because we have to adjust each radiator independently. Which is kind of cool because we can keep it warmer in the bedroom at night but cooler elsewhere.
I try to keep it in the high 60s.

I don’t have a thermostat. The boiler heats the water to 63C and that is piped into the radiators. The house is Edwardian and poorly insulated. I would describe it as cold - think 2 sweaters and a blanket if you’re sitting about.

Mine is at 66 right now, and that’s about where i keep it. I don’t mind being bundled up.

We live in a log home so we keep our thermostat on a constant 63 degrees. A few years ago I installed a programmable thermostat and dropped the heat into the 50’s while we were at work. Well, my oil bill increased sunstantially!! After doing some reseach and questioning the oil company, we found out that it’s best to keep the temp. constant in a log home. The logs cool off quickly and take a lot to warm back up. Our furnace was practically on non-stop during the evening trying to warm the logs back up. So, I switched back our thermostats and we now keep the temp the same 24/7. If the temp outside falls to -40 below zero, then we use a ceramic heater for a few hours to warm things up a bit.
We have all grown accustomed to wearing a few layers in our house

I keep my thermostat at about 50 degrees whether I’m home or not. I have a nice fluffy robe and a pair of slippers and both my kitties came with fur coats (hahaha). So
We rarely turn it up unless I’m feeling poorly.

I was shooting for 65 degrees at all times. But my hands and feet get so cold due to poor circulation. And when they are cold, they ache.
So I am back up to 70 in the AM down to 68 then down to 65 when I am in bed.
By the way, some people who suffer from Seasonal Affective Disorder (S.A.D.) get depressed if they stay too cold for too long. N0-I am not making this up! Just another thing to keep in mind.

That sounds interesting about the logs cooling off the way they do, but it makes sense when you think about it. -40 is a little colder than I have ever experienced. My record was -20, but we were working outside for a couple hours, so I got to really experience it!
Carol, I am aware of S.A.D. A lack of exposure to sunlight can have a similar effect. A lot of people are helped by spending some time under a sunlamp, which can have great results.
Personally, I am very comfortable at 68, and when we go to sleep, we turn the heater low. A big down blanket works enough to keep us warm.
Thanks for all the great comments everyone!

I put mine down to 65 during the day (low enough that it never clicks on down here in TX) and put it up to 70 when I get home (where it clicks on occasionally but not often). In summer is when it really counts down here. I usually only cool the place down to 75 or 76 when I’m home, and I put it up to 87 when I leave for work.

65 day, 63 night, if not at home 60. Gas bill under $50 last month–live in California so even though it’s winter, it doesn’t get that cold. Without the heater, natural temp indoors would be 58-60. I also use 2 space heaters whenever I like it a little warmer.
Electric bill was $100 higher than usual BUT was based on estimate, not actual. Last year I used a lot of electricity but have replaced all my bulbs with compacts, started switching off/unplugging applicances etc . . . so the estimate is based on last years usage and will hopefully be proven incorrect next month.

ON the other hand - kudos for switching to CFLs! They save us a lot of money! Unplugging your appliances and other actions will also save a lot of energy and save you a lot of money. Great job!

Um, unless your co-worker has a couple of those hairless Mexican dogs, don’t these pets come with a fur coat option already installed? Besides, 75-F degrees is pretty toasty, IMHO. We live in Maine, colder than a lot of places, and we rarely lead the thermostat above 65-F, even in heart the winter, and I can’t sleep if it’s too hot in the house. Keeping it at 75-F, 24/7, is just gives you some sobering insurance that you will pay through the nose when the bottom drops out of the thermometer!

I’m a bit extreme, but I leave the heat off entirely. If it gets below 60 in the house, I may turn it on. But for the most part I don’t use it at all.
I live in a ~1000 sq. ft condo and my electric bill is usually about 50-60 dollars.

I’ll have to agree with some others - animals have fur! We have our thermostat at 69 when we’re home and 63 during the day and overnight. Our cats’ fur gets a little thicker in the winter, so they adapt very well!

I heat with oil, live in northern Maine and keep it at 60 most of the time - when it’s really windy and the wind chill factor is well below 0, I might put it up to 65 long enough for the furnace to come on then it goes back down. I grew up during the Nixon era and the energy crisis so I’m used to it.

75 degrees?! Wow-that is pretty warm. I keep ours at 71 at the most; any warmer and I feel like I’m in a sauna.
I turn it down to 64 at night downstairs and usually 70 at night upstairs. During the day anywhere from 69-70 in the entire house since I’m home most of the day with the youngest.

We keep ours at 62 degrees when we’re home. If I’m working from home, I’ll often use the space heater to keep my area warmer. When I at a hotel with a programmable thermostat that tells you how hot you’re setting it at, I like to set it at 72 degrees.

65 when home awake. 50 at night. No warm up in the mornings. 45 when gone. Space heater in the bathroom as needed. But as I primarily use a very efficient woodstove (2 cords a year) the heat is not on much. Highest winter electric bill has been $44. Summer bill (no a/c needed) drops to $28. Sweatshirts and flannel shirts! Yes!
