Agreed. Funnily I'm from a more temperature country and she's from where I'm at now, but she's the one that is always cold and wants to keep it at ~22. I ain't gonna argue considering she pays the electricity bill, though.

26?! Hell, I can't even sleep if it's above like 20C in my room. My bedroom right now is 10C (vents blocked to keep it extra cold) and that's about the perfect sleeping temp. I'd go that cold in the rest of the house too but my pet snake probably wouldn't appreciate it.

I grew up in cold but have spent almost two decades in humid subtropical. If it's 20ish outside, I usually won't turn on the heat, but 23 if it gets any colder (though that's in part because old japanese house loses heat like crazy. 21 is good for me)

19C during the day, 14C at night, 22C in the office because sitting still and concentrating is no way to keep warm.

I can't wait until it's warm enough to just keep windows open 24/7 again.

I keep my place at 15.5c in winter because it’s super drafty. (I’m getting the siding redone soon, I really hope that helps, but ultimately we have the same climate as Siberia so there’s only so much to be done) even at 15.5, it’s still about $200 USD/mth to heat, but at 18c it more than doubles in cost.

I’m like your wife; made for warmer climates. My ideal temp is around 30c, and I’m cold at 23, but I have heated mattress pads on my bed and couch (much much much cheaper to run than furnace) so it’s not too bad overall. They are a bit pricy up front, but definitely worth the spend.

Perhaps that sort of thing would be a good compromise for you two; a couple heated chair covers or couch cover or something to bring her temp up while keeping the overall temp lower.
