The lizards in charge of my buildings boiler (we dont have thermostats in the suites) turned on the boiler when it was finally dipping to 9° C, and then there was another mini blast of summer where it was peaking 26° C. I think it would be reasonable to wear a jacket or removable sweater outside, perhaps a blanket inside, but they decided that actually we needed full blast heat. Luckily I found my secret shut off valve, nyaha haaaa.... I can finally enjoy the chill.
Years ago, I lived with a roommate elsewhere and it was during a big heat dome. I went to my moms to escape the heat in a different city for a week, I couldnt deal with 40° C in the day and 30° C at night (no A/C, we have never needed it). I came back and my roommate had the heat on maxed out at 36°, so the boiler had been on. She was walking around in a bra and shorts. I never asked her what was up with that, it was mere silent acknowledgement...
