Not the same effect exactly but I live in an 70s era apartment with heated ceilings in a couple rooms (which I didn’t even know was a thing). It was a similar experience where initially it seemed great in the winter how quickly a room felt “warm”. But quickly you notice the air itself isn’t as warm which isn’t very pleasant and wait, I’m not feeling “warm” anymore I’m feeling “very hot”. I basically gave up using them after the first winter except turned up sub-perceptually at like 25% just to add a bit of heat input to reduce the days where I need a space heater.
