I bought a temperature sensor for my room because I was curious about how cold it actually gets, and how fast it loses heat, and it's actually not as bad as I thought it was. Doesn't seem to go below about 12 or so, although I think that's mostly down to body heat, the electric blanket, and my computer all slightly warming the room. But then again, my bathroom remains quite stable at around 15 regardless, so maybe there is an itty bit of insulation somewhere

If anybody's wondering why I don't run the ducted heating constantly, it's because of this:

The temperature sensor is in the hallway, which doesn't have a heating vent, so once you turn it on, it will pretty much run until summer, turning my room particularly for some reason into a mini marble bar (localised entirely within my bedroom! No you may not see it.), and they absolutely refuse to install either a temperature sensor into a bedroom, or a heating vent into the hallway.

Bonus: the temperature sensor in the bathroom (no heating vent + a giant skylight):

Tonight feels really fucking nippy though, even with the heater on, the electric blanket on full boar, and a temperature reading of 20°. It feels like -1 outside, according to the BOM boys, so I guess that's justified
