Central Heating

Many have suffered from being in a building where there was a centralized thermostat for the whole building (or the whole floor), with the predictable result that some rooms are way too hot or way too cold. (Sounds like a metaphor, watch for it…)

Things were even more extreme in the former Soviet Union, where there were centralized heating plants for a whole city, and the hot air would then be pumped out to individual homes and offices. So basically the whole city had one centralized thermostat.

What a nice and simple solution there is: give each room its own thermostat. First, there is automatic adjustment from the thermostat to keep it from being too hot or too cold. Second, the people in the room at any one moment can choose to adjust the thermostat according to their preferences.
