I've been wondering how the heat controls on high power heating element in
electric stoves, baseboard heaters and the like work. Is it PWM?
Nope, that would cost too much.

In a way - they're usually controlled by a thermostat, which turns off the
power at one temp, and back on again at another, lower temp.
** Bollocks.Sort of like PWM whose pulse width is measured in hours.
yes, at a very low frequency. typically 1Hz or less.I've been wondering how the heat controls on high power heating element in

Why? Isn't what you just described?"Rich Grise is Wrong Again "
For coils and hot plates, power control is by an adjustable thermal switch
that cycles on and off at a rate determined by its own self heating and the
setting on the dial.

Admittedly, I could have said "minutes" instead of "hours,"
but that all depends on the application.
Hey, wait a minute...** The "hours" bit is totally absurd.
As even a fuckwit like you should have picked.
