I just read this on-line and was surprised.
"Most room heaters with a temperature control work by controlling the duty cycle of the heater, which in turn controls the energy output. However, without temperature feedback, its up to the user to continually adjust the heater for maximum comfort."
I thought that all room heaters had at least a bi-metallic thermostat, but not so, according to the quote above. I know that many room heaters do turn off and on based the setting of a rotary control; what causes them to turn on and off if not a thermostat?
