23 all year round

I keep it 68F(20c) downstairs, but the main house temp is regrettably 73F(22C) and I fight to keep it that low because the rest of the house is cold blooded.

Usually around 18-19, 15-16 overnight

During the cold season
20°C, 18°C at night and when away

During the warm season
23°C, 25°C when away

I try to keep between 68 F and 72 F, but uh, the thermostat's method of measuring the actual temperature in the apartment is completely, laughably busted, so... hot days it goes on 62, cold days it goes on 84.

By thermostat are we talking about heating? I'm cold-tolerant so I typically set mine to 15.5 C. If it gets any colder than that indoors it comes on

Here's January of this year. San Francisco, so pretty moderate weather

typically don't run heat during the day, and low 60s at night (if at all) during the winter. Large temperature gradient throughout house, typically.

South facing windows gives kitchen and living room a greenhouse effect, particularly in the winter, hence the large daily temperature swings:

It depends on where you sleep. Basement vs upstairs can make a huge difference at the same thermostat setting. I keep mine set to be between 19°C and 25°C and don't have trouble sleeping.

Speaking of which, anyone else use Home Assistant / Z-Wave?

71 in winter

70 in summer

Upstate NY - 64°F in the winter, no A/C ( just a half-assed whole house fan).

I acclimate to to the heat. I've lived in the South with no AC at all; 80F with humidity control is cushy by comparison.

Summer: open windows until heat and/or humidity causes concern for my electronics.

Winter Day: 68F Winter Night: 58F

In summer it's off and in winter 20,5-21℃ at daytime and 17℃ at night.

Why would I care what temperature it is when I'm sleeping? I'm asleep.

That aside, 60 winter and 73 summer.

80f / 26.6c

17-20 C

I've managed to have restful sleep at 78 with two fans blasting me, plus a window open to let in the relatively cooler night air. It's doable, but the body takes time to adjust. Humidity can be a big factor.

65 in winter is kind of understandable, since you could layer up or heat a selected space or yourself easier.

My usual comfy indoor ranges would be 70 daytime, 68 night for winter, then 75 throughout in the summer.

70 in the winter. And, and we don’t have AC because most days are cool enough in the summer.

It's always set at 19°C at night and 20°C for the day, all year long. But it's only heating, there is no AC.

67-68f in the winter, 74 in the summer + fans to supplement when it gets really hot/muggy.

Neither are my ideal temperature, but it lowers the bills and helps reduce the harm done in terms of energy consumption

Year long lowest possible to keep whatever fluids are in the radiators flowing. Not off but not too on either. And then open windows to regulate temperature.

My building is hot OK...

When I visit the US I find that I usually set it in the mid to high 60s for optimal comfort.

18 c - 23 c.

I'm originally from Florida, so 78 is what I usually leave mine at during summer.

I live in California’s San Joaquin valley. It gets hot in the summer. PG&E bill is high as hell. Having your place cooler than 78F is a total luxury. In my place keeping it at 78F would mean a couple $600 bills. I have since gotten solar but I’ve heard PG&E increased their prices twice since then. And they want to increase it even more.

On the other hand some places like Sacramento used to have super cheap rates and people could crank their ACs on.

I agree that 78°F is way too high to be a confortable sleeping temp, though being in a country where residential AC isn't really a thing and inside temps at night often are higher than that in summer... you get used to it, it'll just never be fun.

My ideal sleeping temp is like 15°C but even if I had AC that seems too wasteful so I'd probably settle for 18-20

72°F in summer / 64°F in winter

Heat to 69 in the winter, cool to 74-76 in the summer.

I keep mine on 64F room temp and hover around that. I use fans in the heat and portable heaters in the cold. But I heard keep it just below 70 in the winter and just above 70 in the summer to have a better bill.

23 in winter and 22 in summer. Nights are set at 18 all year long.

Mine is programmable. In winter it's set to 65F at night and 68F durring the day. When unoccupied it also goes to 65F. I'd love to be able to set it lower because I love the cold but my pet snake probably wouldn't appreciate it even with their hot rock and heat lamp. Durring the summer I have it set to 68F while sleeping 72F durring the day and 78F while unoccupied. I don't shut the AC off while unoccupied because in my area humidity is a much bigger issue in the summer than temperature and removing latent heat takes a long time if you let it build up all day. Currently working on refitting my system for better on demand latent heat removal.

80 in summer during the day, 75 at night, 78 day and night in winter. We do not have heat, and 78 is required for the air conditioning to run periodically in winter to dehumidify the house.
