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.

These are my opinions.  I hate spam.
