I don't think you are asking the right question.
You can build a control loop with a 1 bit ADC. Think of your typical
household thermostat.
I'm not sure what the right question is. I expect it will involve the
sampling rate, the response time of the system, and the nature of the heater.
You also have to consider stability.
