Winter Thermostat Setting: How Low Can You Go?

A couple days ago I performed a highly unscientific poll on the subject of winter thermostat settings. I asked Twitter followers to share their overnight indoor temperature settings and how cold the outside temperatures were in their neck of the woods. My hypothesis was that people are much more frugal about their temperature settings than we are–and I was right!

Based on the responses received the average winter thermostat setting was 63 degrees at night, and the average outside temperature was 31 degrees. Several mentioned that they keep their thermostat on 70, or higher, because they have small kids. We are in that category as well.

A few months ago I installed a programmable thermostat. During winter days, particularly when it is mild (above 50 degrees), we set the thermostat to “Off.” However, at night we have it programmed to warm the house to 72 degrees while we go through bath and bedtime routines.

Once everyone is hunkered down under blankets, we drop the temperature to 68 degrees overnight, before returning it to 72 about half an hour before we wake up and being our morning routine.

As the kids get older I imagine we will drop this temperature down a bit to shave a little more off or our utility bills. Some of the Twitter responses indicated they set their thermostat as low as 55, and one follower even remarked, “We usually knock our thermostat setting down to 40 at night (and low was 17). We get under enough covers that I still manage to get hot!” 40 degrees? Yikes!

Tips For Staying Warm

Properly insulate your home. Besides having proper insulation installed in walls and attics, also check out door sweeps and areas around windows. Hold a lit candle in front of doors and windows on a breezy day. If the flame flickers it is a good indication air is seeping in. Replace weatherstripping and sweeps around doors for a better seal, and caulk around window joints.

Double up on the covers. Seems obvious I know. But many people simply sleep under a bedspread or comforter, rather than a blanket made of heavier material. A quality blanket will help insulate you by trapping body heat and allowing you to drop the inside temperature further.

Gather around the fireplace. In the early evenings a fire in the fireplace can replace the need for central heating, assuming everyone gathers in the same room room.

Dress windows to help keep cold air out. We recently hung curtains in one of our bedrooms and felt a noticeable difference. The room felt less drafty at night, and during the day we pull back the curtains to let sunlight warm the room naturally.

  1. I find the best way to keep warm is to wear a hat inside when the thermostat is low. There are lots of fashionable indoor hats if you’re not a dork like me (I wear a fleece beanie with kitty ears.)

    Also, if you’re going to the trouble of hanging curtains, either hang ones that are lined (they help keep the hot out in the summer too) or invest in a seperate curtain liner.

  2. We have little kids, and overnight our thermostat is set to 16 degrees celcius (approx 62 degrees farenheit). For the morning routine, the evening routine and when we’re at home we increase it to 18 degrees celsius (approx 68 farenheit).

    Last month we paid $500 to have our attic re-insulated. We went from R22 (which was code when our house was built in 1987) to R50 (current code is R40). We can really feel the difference – particularly in my daughter’s room which faces Northeast and has two outside walls. It was well worth the investment.

    • how big is your house, what region of the country do you live in?
      We wanted to insulate and it seemed about 1000 to 3000$, ( noting: ours is a, depending on what you count: a 5500 s.f. home if you count all three levels, just under 4000 just the upper two. We also were concerned about preserving the eave vents, you don’t want to block those or the attic doesn’t have any ‘makeup’ air flow in summer to let heat out the ridge or gable end vents, whichever your house has.
      Did the insulation job include doing that? (“tru-vents” i believe they’re referred to as, in the bays at the intersection of each rafter to wall connection )
      also, then you can’t walk around up there to add lighting, electrical, cable, internet features as your home and family needs evolve very easily. did you install catwalks? or do you intend to just move the insulation around to find joist to walk on?

  3. I probably am worse than anybody, I have it set to 78. This morning I just set it to 80, because it is particularly Cold outside. I feel cold/shivers when it is below about 75.

    I grew up in big drafty house in the midwest where every winter was below 0 and my parents were too cheap to turn on the heat to any thing higher than preventing the pipes from freezing so it was always very cold. That scarred me for life, so I moved to a warm place as soon as I finished school. I don’t like the cold.

  4. Our thermostat is set to 64F in daytime, 52F overnight. Outside overnight temperatures are in the teens. We actually have two heating systems and two thermostats, one in the old part of the house, and one just in the new addition. We only use the one in the new addition, which means only two rooms in our house are directly heated. Temperatures in the rest of the house are typically in the 50s during the day. When we shower, we heat the bathroom briefly with an electric space heater.

    How do we stay warm? By using every trick in the book, basically. I wrote about them here:

    http://livingthefrugallife.blogspot.com/2008/10/staying-warm-with-thermostat-set-low.html

    This has been the most popular post on my blog for the last several months. Apparently, for every degree F that you lower your thermostat setting, you save (on average) 5% of your heating costs.

  5. We live in the south, so our heater is rarely used. In fact, during the winter months we alternate between nothing on, and A/C on.

    In most areas, the electric company has a contract with another company that will come check the efficiency of your home: they check the seals of your windows & doors. If your home needs it, they will install seals to fix any air leaks, and will also install gaskets under outlets.

  6. Hi Frugal Dad,

    I was one of the respondents on Twitter. We keep the thermostat at 65 during the day and 61 at night…but it only gets down to about 45-50 degrees outside at night.

    My advice? Move to a warmer climate! :) (I know, entirely unhelpful…but it’s what I did!)

    -Erica

  7. We keep our place at 65. It gets cold in the Midwest, so you get a feel for being cold. When it gets back to above freezing after a long winter, we are wearing shorts!

    I would go even lower if we had heated bathroom floors!

    After baking, we’ll keep our oven cracked open (we don’t have kids or pets) since we are near the kitchen for the next few hours. Might as well take advantage of the energy used. In fact, I just wrote about this yesterday.

    I just wish we had a fireplace. :(

    Stupidly Yours,

    Matt

  8. We keep it at 67 during the day (5:30am-10pm) and drop it to 57 at night. We’ve had a pretty cold winter, but we’re all comfortable (2 adults, 1 2 year-old) with the indoor temperatures. The 2 year-old likes to run around with as little clothing on as she can most of the time regardless!

  9. we keep our house at 62-64 degrees. The outside temps have been about 20-30 degrees so far (in central NJ).
    We just throw on an extra blanket at bed and we have many throws on the couch.
    Sometimes when I get up I set the temp to 70 just so we can all shower with the heat up higher.

    I just recently got a door / cover for my pull down attic steps (it goes inside, it is custom made all styrofoam.) It has made a huge difference in my attic not sucking up all the warm air.

  10. I’m embarrassed to admit this, but I don’t know how to program my programmable thermostat!

    We keep the house at 69 during the day (depending on humidity) and the evening as we work at home and someone is almost always here.

    At night we turn it down to 68. Any lower and it is just too cold when my son gets up to shower in the morning at 6am.

    We live in the south, so lows here are generally around the 40s – 50s, with drops to the 30s now & then.

    If I could figure out how to program the thermostat I would drop the temp to 65-66 at bedtime and have it come on to 69 early in the morning. I’m gonna try…

  11. I work for a heating company and was told a few years ago by our equipment technical rep. that if you lower the temp. on a programmable thermostat more than 10% that you actually reduce overall efficiency. Efficiency is reduced because the furnace consumes more fuel to heat the house back up to temp. than it would have taken to maintain a < 10% change in temperature in the first place. Something to consider.

  12. We keep ours at 68 during the day and 63 overnight. It’s anywhere between -10 and 20 overnight in Iowa. We have a 1 year-old and it doesn’t seem to bother him. As someone else mentioned above, the fewer clothes the better as far as he’s concerned. Most of the time he doesn’t want socks on – and it sure doesn’t seem to bother him.

    We have heated mattress pads in our bed. Turn them on about an hour before going to bed, to warm up the bed, and then typically turn them off (or just down if it’s a really cold night). I like this better than a heated blanket because the heat is underneath me instead of on top of me (which to me can feel suffocating).

    I think the heated mattress pad is well worth the investment because it means we can significantly turn the heat down for the rest of the house overnight.

  13. Fortunately, I am the only one in my house except for occasional short-term visits from my sons. I dress in layers during winter (sometimes even a hat) and keep the temperature downstairs at 60F and upstairs, it is off until I go to bed when I set it at 55F.

    I revel in using the least amount of fuel oil possible even though the price has come down significantly. All the “extra” goes to my ING account. Wooohooooooooooo! In January, I was actually able to order 200 gallons of fuel oil for less than I paid for just 100 gallons last year….talk about feeling RICH!

    When my sons are home, they put the temperature up to 70F, which is suffocating for me :-) .

    I live in NY on Long Island, so not as cold as upstate.

  14. @ Dave – I have a heat pump and was told a similar thing when they were installing it. They said that I should only let the temp fluctuate 3-4 degrees otherwise it will be very inefficient.

    To show what a poor listener I am, I have it set at 67 in the day, and 62 at night.

  15. We recently installed a programmable thermostat and we have ours set so that at night it is 60. It warms up to 64 while we are getting ready for work and then drops back to 60. Right before we come home it goes back to 64 and then back to 60 at 10 when we go to bed. On the weekend we keep it 64 during the day and still 60 at night. In my sons room there are sliding glass doors so we have vertical blinds, curtains, and blankets over those. We also have a small electric heater that we use on the nights when it is 3 or 4 outside.

  16. It’s been below zero here the past few weeks at night and we keep the thermostat set at 62F around the clock. Our house is old and we have been adding insulation as we go along, but the main problem is the huge picture windows in the living room. They are thin and face the north side (I’m guessing they are close to 70 yrs old). As long as you stay away from those windows (which the computer is right next to) it’s not too bad in here. We have two little kids in the house and if they are cold, they’re not playing hard enough.

  17. During the day, I turn it down to 58 and wear a sweater… At night, when we take our showers and relax around the house, it’s about 62. Outdoor temperatures bounce between zero and 25 degrees.

    Born and bred in Pennsylvania – bring on the cold! ;) In all truth, I can’t wait for spring.

  18. At night, I sleep with it on 62. I sleep under multiple blankets. I keep it on 66 during the day. I just wear warm clothes during the day.
    In the summer I set it on 80 in the day time, and the night is 76 or 77. Our winters are 20s to 40s for lows, and 30s to 60s for highs. The summer lows are 70s to 80s, and highs are 90s to 100 .

  19. ok . . . this might be really stupid . . . but i have been told for most of my adult life that you should not adjust your thermostat much – that it’s the most economical to leave it at the same temp throughout the season. so that’s what i’ve done for years. has anyone done the math on that one?? does it really pay to drop it down at nite??

  20. We keep at 61 around the clock with a few exceptions. Evening bathtime is the biggest issue, and we’ve mitigated it somewhat by keeping the bathroom door closed and making sure PJs and bathrobes are in there when each child comes in.

    This is our second winter with a lowered thremostat, and we’ve found that once we got used to it, everything else feels too hot.

    We’ve reduced our oil consumption by more than 50%, year over year. Fairly significant savings!

  21. My two cadet wall heaters are set at 55 but rarely come on. The bathroom heater is used when needed only. The rest of the time I stoke the woodstove before bed, and when it burns out (as it usually does) during the night, the temp. drops to as low as 55 when the cadet wall heaters will come on. But then, I like to sleep cool and use flannel sheets and two quilts on the bed.

  22. I suppose we’re fortunate in winter here in Florida. We really don’t even need a heater at all. The other tips you gave such as extra blankets, etc. do the job.
    But in summer the story changes! A programmable T-Stat is a huge cost saver in the Florida heat. Most people set them to allow the temp to rise to around 80 degrees during the day and then drop to the mid to upper 70s at night.

  23. We keep our house at 60 during the winter. At night, the thermostat is programmed to drop to 58. We bump it up to 65 or 68 when we have company. I also have it set to go up to 62 in the morning while I’m getting ready for work.

    Even when our children were babies, we kept our temperature set this way. They never had a problem with it.

  24. The average was 63 degrees- WOW! That is way better than our family does. Your set-up is almost identical to ours and we keep it at 68 throughout the night.

  25. We have a two year old who refused to be covered by a blanket, but we bought him 2 warm sleepers and a fleece fitted sheet for his bed. Overnight we turn the thermostat down around 64 or 65. During the coldest days, we may turn it as high as 68, but usually just try to move around more to warm up. We have an old house that is kinda big and I don’t want to spend big $$ heating all the rooms when we’re just in one or two of them at a time.

    We don’t have a programmable because we’re usually home (my aunt keeps our son at our house during the day) and can easily adjust.

    I have a question for those who keep their thermostats higher…I noticed when I lived at home where my mom stayed cold and kept the thermostat around 74 I had a lot more colds and sinus problems. Is this a problem for any of you, or am I just a weirdo?

  26. I’m sure like most couples, my wife likes the thermostat set higher than I would! One of us is always messing with the thermostat to get it just right, but I like the idea of of a programmable thermostat.

    We could sit down together, hopefully come to a “temperature treaty” and program it in.

    Good tips!

  27. Programmable thermostat set for 68 when we’re home, 62 between 10pm and 5am and when we’re out of the house. We had been setting it at 58 for down-time but nighttime temps have been in the 20s and it was taking too long for the house to warm up in the morning.

    I’d rather keep it at 72, but as it is I have wool socks and sweaters to keep me comfortable; the two little boys don’t stop moving long enough to notice if it’s chilly :D

  28. We live in Vancouver BC
    We have an old 37 year old house and we just recently replaced our natural gas furnace to an 80% efficient one and got a programable thermostat. We set it to 71.6 F from 6am-9pm and 62.6 from 9am-6am. We have a portable electric heater with a programmable thermostat built-in in the nursery that kicks and try to maintain 70 F and same for in our bedroom but at 68 F. We find that having a combination of central and portable heating saves money while keeping us warm all winter long

  29. It’s 4 degrees outside right now. And, my thermostat is at 50 degrees, all day, all night. I telecommute for my half-time job and then the rest of the day, continue to work at home on my business. So I’m in 50 degrees all day and all night. I wear socks, a snuggly blanket, an lots of layers. I live alone with a Siamese cat. The cat is the one bothered. Any time the forced air heat comes on, she runs to a floor plate and lays on it. Poor kitty. But, seriously, I now walk into a house at 69 and I’m uncomfortable.

  30. We also have a programmable thermostat. It has really reduced our heating/cooling costs. In the winter, we keep it around 69 during the day (until 10:00 P.M.) and then it drops to 60 (we are well insulated so our place never gets cooler than 65). Our night time temps are usually in the 30s-50s (we are in North Louisiana)

  31. I usually just turn the heat off. My little house is pretty well insulated and it doesn’t drop that much below freezing in Seattle.

    Of course, I usually have the furry canine radiators in bed. The short-haired breeds in particular generate a lot of heat. ;)

  32. I didn’t realize there were automatic thermometers, a great way to control the heating and can save some money. I really like your strategy, keep it down during the day and when sleeping and higher when home.

    Another way to prevent from loosing heat is too put a sock pillow at the crack of a door to prevent hot air from escaping or cold air from coming in.

  33. My husband (until we got our first gas bill in our new house) kept the heat on 72. Now we keep it on 65 when sleeping and not home. 68 when we are home and awake. I have a 17 year old, a 2 1/2 year old and a 6 month old. Only the 17 year could tell the difference, he was walking around in shorts ! I told him to go put warmer clothes on. I keep the 2 little one dressed warm. When I was a child the heat was always on 60.

  34. I feel a chill just reading about this.
    I grew up in the midwest and froze, so first opportunity I had I headed for warmer climates. I do try to keep the temp at 64 when we get up and after everyone is home from school/work. At night we turn the thermostat down to 58, but this is San Diego where a cold day is in the 50-60s. By the look of my gas and electric bill, I don’t think any home has the proper amt of insulation.

  35. I love this kind of forum, because it really gives me a good idea of what real people are doing. We keep our thermostat at 62 degrees at night (between 10pm and 6am). I turn it up to 66 for the morning when we are getting ready to leave, then back to 62 degrees while we are gone. For the evening, after 5pm, I’ll make it a comfortable 68 degrees. Our gas bill wasn’t too bad this past month compared to others I’ve heard. We pull our drapes too though, which I think really helps.

  36. We keep our thermostat at 62 when no one is home or at night. When someone is home it is probably on 65 to 68 depending on who is home and what they are doing. You can stay warmer cleaning house than you can sitting and reading. Our problem is that while we have a programmable thermostat we have a geothermal heat system. When you up the temp by 3 degrees or more the backup system kicks in. Thus I can’t really use the programmable thermostat because I would have to set it in 3 degree increments to change temps. Does anyone else have this issue and how have they dealt with it?

  37. So we all have different ideas, mine is 56-62 degrees with a programmable thermostat,5:30-7am,3:30-7pmI have a 94% efficiency 2 stage Lennox furnace. My heating service company says you should not have more than a 7 degree swing for the furnace.They also say not to close doors or shut vents as it creates negative air and the flow of heated air is critical to the overall efficiency and life of the furnace.So if you wear socks make it wool,shirts make them a sweater,Northern Indiana has been at an avg 15-20 outside so we cant wait for spring. 5 level home 30 years old avg gas/elec is $188/mo budget plan Nipsco.I despise sending money thru the vents. Not an eskimo just conservative,cheap to some,frugal to some but We all work hard for our money to just burn it.

  38. I heat with wood and live in Vermont. So, my house has a big fluctuation. It will get as cold as 40, and if I really stoke the stove we’re all in t-shirts. One of my favorite things is a hot water bottle I sometimes just carry around with me and it does a lovely job of warming the sheets before I climb into bed at night. My children each have their own bottle. I have a good friend who has a more efficient newly built house and he only has one fire a day, if he goes away his house will stabilize at between 39 and 42 and that’s with outside temps around -10!

  39. My hat is off to Sunni. most people think we are nuts when we tell them we keep our house at 57/53 in the winter. But hey wearing extra clothes and laying under blankets is free, heat isn’t. If we just sit around and watch tv we will get cold, but if we keep ourselves busy we don’t even notice it. Call it another form of motivation to get chores done. :)

  40. We have small kids and live in Wisconsin. Our default on our programmable thermostat was 70 during the day, 62 at night. We tweaked the daytime temp down to 69. We actually prefer to sleep at night when it is cold. As our kids get older, we’ll probably drop it further.

  41. Very helpful forum – while we are at it, could someone let me know:
    1. What should be the thermostat temp when you are away on holidays for 2-3 weeks? I have heard it should be enough to keep the pipes from freezing, but not sure what that temp is?
    2. What’s the avg consumption in a single unit household?

    Thanks in advance for the responses.

  42. We heat with wood and have ever since our kids were babies. We have electric baseboard heat so each room has its own thermostat. The heat in the main room (living room, dining room, kitchen) doesn’t work, but the wood burning stove heats the whole house. We live at 8500 feet in the mountains of Colorado so it can get cold! It is 0 right now. We used to keep the heat in the kids room at about 63 at night when they where little. Now we do not turn it on, they don’t need it. Kids are tougher than you think. A lot of the time it is about 56 in the house when we wake up and I usually have to make them put socks and a sweatshirt on (we have hardwood floors and tile). We homeschool and will only start a fire if it is below 65. We are lucky because the couple that owned the house before us designed it for passive solar. When the sun comes through the sliding glass door in the afternoon it raised the temperature of the house 8 degrees!

  43. Apparently we’re more hardcore than I thought! With temps in the 20s, we keep the thermostat at 60 at night. Of course, we pile on the covers, the down blanket, and soak up the warmth of fleece sheets. We consider the chilly evening showers an adventure, I guess…

  44. Hm… we keep the house around 66 during the day, and that’s with a four-month old baby. We get down to somewhere around 63 at night.

    We bundle the baby up in fleece PJs, a fleece swaddler, and often a blanket on top of that. Maybe we’re just blessed with a baby who is a heat machine like her daddy :)

  45. Some of these temperatures are people keep during the day are crazy. A few years back in the days after college, I would keep the apartment at 55-60 degrees – always. These days… Heck, I make money and want to be comfortable in my own home without having to dress up like I am going out into a snowstorm.

    We currently keep the house at 69 from 4pm-10pm (we get home at 4:30) and 55 the remainder of the time.

  46. Eric — I have money, too. For me, I see two hands out. One hand is the utility company. The other hand is mine. I can put my earned income into the utility companies checking account or I can put it into my savings/investment account. Personally, I prefer to put money I earn into my accounts, a decision that has benefited me greatly over the years. If we all chose to live at least a few years like we did in college (we did survive quite well, thank you), we’d all be able to stop being employees long before we currently do.

    I have also found that my body actually has acclimated to the colder temperature — and I originally hail from southern California. Here, in the NW (I’m in Washington, minutes from northern Idaho), it’s very cold in the winter. Last night, my 19-year-old son and I went to see a movie. He went without a coat. It was 30. He said he was fine with just his shirt (no sweater). I am taking care of a friend’s home, which is set at 69. I about died when I went in yesterday. It was uncomfortably warm.

    It’s not crazy to save one’s green, Eric. Actually, I think it’s pretty darn smart.

  47. I am asking the best, most efficient way to set the thermostat on a geothermal heat pump. We just installed one and are seeking advise.

  48. Hi we live in Middlebug, Fl jus 30 minutes outside Jacksoville, Fl this morning the temp drop to about 43 here I set the thermostat to about 75 and my wifesaid she still feels cold What temp should I set it to.

  49. Old topic, I know, but I thought I’d add to it.

    I’m glad I found this topic. I thought I was a freak of nature! Over the years living in Alaska, I’ve gotten used to keeping the house cooler. During the day, I’m usually happy with 64-66, though sometimes I get a chill and crank it up to 68 or 70, but never higher. At night, I’ll turn it down to 58, though in the winter, we keep it at 62 to help keep pipes from freezing. Any higher than 62, though, and I wake up in the middle of the night sweating!

    I travel frequently, and I now always have to crank the hotel’s air conditioner up to maximum before going to bed just so I can sleep.

    Maybe it’s that I’ve really gotten used to the feeling of being chilly but buried under several nice, warm blankets. It’s a cozy feeling. Sleeping in a warmer room with fewer/thinner blankets just isn’t the same.

  50. If you have a heat pump system, it is best to find a temperature that you feel comfortable around 68 degrees, two up or to down, and leave it there. (In todays economy, every two degrees costs you around $20 per month) You will spend more money adjusting your thermastat or setting it automatically at variable settings throughout the day. It takes a greater effort and more electricity to increase the temperature even by two degrees. Oil/gas furnaces do not. If you are going out of town and will be gone longer than a couple days, it is then more economical to reduce the temp to around 60 and schedule it to increase for your return.

  51. does droping your temp’s at night save more than keeping it the same all 24 hrs? i was told something about bringing all the walls back up to temp takes more energy than just keeping it the same. house it properly insulated and windows and doors are new.

  52. We just bought a house and at first kept it at 68 in the day for the 2 little ones (an infant and a toddler). After seeing our gas bill, I used the programmable thermostat and set the day temp to 65 and night temp to 62 and this is amazing for me since I’m the type who gets cold all the time. However, i think this is actually a good thing because now my body is better at regulating my own temp and my kids have adjusted fairly well. When it gets really cold at night we just use the small electric heater for the bedroom. Also shaved off like 20 dollars on my gas bill…nice.

  53. My house is set to 55 and only goes up to 66 from 300pm until 930pm then back down. But I question if that is really worth it. In the worst part of winter oustside temps in the teens and twenties, the furnace turns on to get to 66 it takes at least 2-3 hours. Is that really saving anything? Its an older house. I read all these different rules about at least 8 -10 degress for at least 8 hours. But nobody gives any instight on how long a furnace shoudl run to bring it back to t eh warmer temp. There has to be some kind of break point where your just wasting time, energya nd most of all money. Not to mention freezing at the lower temp

  54. We keep our thermostat at 55 degrees day and night. We live in the midwest and the temperature as I am writing is 21 degrees. Layering our clothing and using wool blankets at night helps. Our home is heated with propane and we think we are saving a considerable amount of money each month. Requiring one less tank of propane a season saves us hundreds of dollars. Just can’t wait for that warm summer sun!

  55. I’m temporarily living with my fiancees family while we save some money and his father is sweet but he always keeps the thermostat at 68 degrees.. I’m anemic so my skin and bones hurt when its this cold I’m suffering and he gets angry when I put it to at least 75 he said if I don’t like it to chip in for the bill.. I’m in nursing school taking many classes I can’t work. So we secretly got an electric heater and I put it up until room temperature is 80 hehe. His house is big though two floors and attic where the older sister lives atm.

  56. We keep our house at 60 degrees all day and night in the winter (we live in the midwest). We used to keep the house at 58 degrees in the winter years ago, but we’ve since put it up to 60. We just like to be as frugal as possible, and we’re cold-weather people anyway so we’re not bothered by the lower temp. Just wear socks and throw on a sweatshirt around the house and we’re good. We actually hate going to homes with the temp set over the mid 60s…It is way too hot for us!

  57. Mine is left at 72 all day and all night…the rule is DO NOT TOUCH. I live in a very cold part of the Midwest…it’s comfortable for all of us. Bill runs 60-80/month. I don’t mess because it’s not efficient to have it going up and down then back up etc.

  58. It is more efficient to have the temperature fluctuate if you set it right. People often think that having the system get it back up to temp is costly. Your furnace runs at one pace, so it’s about how often your furnace runs. Unless your temp varies a huge amount or you have a huge inefficient home it will benefit you to turn it down at night when it’s cold out. 72 is pretty high. I set it to 62 at night and 66-68 during the day.

  59. I live between Chicago and Rockford IL and we have a temperature difference of approx. 10-15 degrees both summer and winter from Chicago. I set my programmable thermostat to 70 daytime and 66 night time (14 year old, 2200 sq.ft. home). We have had a colder than normal fall and for a 30 day period of Oct. to Nov., the report I receive from the gas company show that I used 56 more therms then the most efficient homes and 32 therms more then homes rated as good (did not pay much attention to this while I was working; now I’m retired and it is of major concern). For the next 30 days I have lowered the settings to 69 daytime and 63 night time to see if that will make a difference. I have also contracted to have some windows replaced that have the most drafts and the attic reinsulated. I’ll use plastic to seal other windows off. In the summer I set the air to 78-80 only. As far as I am concerned, never buy a home with a lot of windows you’ll regret it over time.
