I don't think he can gradually control the power, just turn it on and off. A thyristor or something for kilowatts of power would be expensive. This makes a PID controller excessive: just heat until it reaches the target temperature and then turn it off. Turn it on again when the temperature has dropped a couple degrees if you want it to keep a temperature.
