 Plus minus heating dial.

Show & Tell: Why do 100-yr-old buildings have high energy costs? 

Radiator woes: the control knob offers vague +/- options. I cannot set an actual temperature to regulate the heating system. This is why 100-yr-old buildings have high energy bills. 🛠 Not only that, they have severe health impacts, especially on older people.
