Oh my god, they turned the heat on here

I was shocked to find the heat on today. I use my heater as shelving, since I have little furniture. I thought both heaters (one in the living room, one in the bedroom) were off, but I picked up something off the living room one earlier today and it was warm! They're the hot-water radiator type heaters, and I guess this one wasn't all the way off, so it came on when the building heat was turned on.

Wow! It's "cool" today, but that means 21C. I guess it's better to have the option of heat, but I find it pretty amazing that the heat is on already. I cranked mine back off, I still have the windows open during the day (and last night was the first time I shut them all at night, it was down around 16 C), so I'm not cold yet!
