u can do that with a relay will be easy.. i think...
connect the heater plug to the relay. and switch using controller. that easier i think.

yes this can be done by using a single relay only ..no need to use SCR

well.. i got a better idea.. you need not to switch on/off the SCR, better is.. simply control the gate voltage and the o/p voltage automatically gets controlled. and for this purpose use an optocoupler to connect the SCR. this is the easiest way..
