What temperature do you keep your thermostat?

Winter: 18 °C day / 16 °C night
Summer: 27 °C day / 24 °C night

(The numbers are weird because I have a Fahrenheit thermostat with handwritten Celsius labels taped over the Fahrenheit ones. I didn’t think to buy a proper thermostat when I was in Canada, although that probably would violate my lease anyway.)

I have a bit of a tree-hugging bent, and I’m too poor to afford a large electric bill. Biking everywhere and being outside a lot has probably widened my range of comfortable temperatures.

Is it a programmable thermostat? When I moved into my house mine was set in F and it bothered me. There was thankfully a thermometer outside that had both so I would go look to reference. Then I realized that there was a switch behind the thermostat to change from F to C and I just had to do a factory default.


That said, I keep mine at 15C, in the morning it goes up to about 20C as I'm always very cold in the morning due to being super tired, so it makes it a tad easier to get up. It then goes back to 15C by the time I'm ready to leave for work. At lunch I have it go to 20C then back to 15C. I can only do 4 programs so I can't do anything past that.

When I get home, I will usually manually override it and set it to around 20C for supper, then put it to maybe 18C for rest of night, then end the override before bed. I have a split level house and my office is on the higher level, so when I put it at 18C it's probably like around 20C in the office while the living room and kitchen are at around 18C.

This fall I actually got 3 free gas bills due to my saving last year. That was pretty awesome. My gas bill is usually around 100 bucks per month.


I don't have AC other then a portable unit, but I had that thing running non stop this summer. It's so loud though. I need to tie it into my existing ductwork or something.

We keep ours at 65F. I'm not going to bother figuring what that is in Celsius.

I wish. I have to change the thermostat manually every night and morning.

They're not too expensive, and they'll save you in the long run.

I've actually thought of getting a more advanced one, I would love one that can be interfaced via IP but those seem to be far and few between. Say I decide I'm not going home for lunch then I could remote in and cancel the program for the heat to go on at lunch, and stuff like that.

If you have one of those fancy GPS-enabled smartphones, it could automatically change your thermostat whenever you come within so many kilometers of your house.

Speaking of thermostats, I did this little project a yearor so ago. Fully custom highly programmable thermostat. Works great especially since I work random shifts so I don't have a steady work schedule. First full winter using it though so it's hard to tell how much I'm really saving, if anything, but it sure is convenient!

Main dashboard view:


Relay controller:



Server room sensor:



Hallway sensor, hidden behind a magnetic light:



Din Rail:


TBH it looks more complicated than it really is. This just acts as a sort of "patch panel" for the sensors. The bottom row is simply power distribution. I can just tie to any of the empty DIN connectors to get +5v and +12v. That's a slightly older pic, now I also have various sensors for stuff like monitoring for power outage, battery voltage, etc... So everything connects there.
