Valve theory is trivially demonstrable to be wrong
While this is true of thermostats as such, not all heating controls are thermostats. My parents’ house had wall-mounted ovens which worked like a kitchen stove: They put out heat proportional to the setting. As an aside, central heating seems to be rare in Norway; instead each room has its own heating. I’m not sure why this should be so.
