I disagree on your definition of "real" :-)

Baseboard heaters for instance are either on or off.
Water radiators have valves with different settings (other than on/off), but
also are controlled by thermostats, sometimes many of them in the room, and
usually with a safety to turn things off.

The thermostat is in the room (or sometimes just the house!), and we have
reason to believe that in the future we'll want more detailed control over
the heaters...

So my take is that *heaters* do not have a thermostat, but rather a heating
system or Climate Control system would have that.

Not that the computer says it is a heater, but rather, the computer says that
it creates heat.

I think it matters, but I think it's a question of different facets.
