Actually that is not a problem when you use feedback. The feedback will even compensate for natural variation in heat generation quite well. If some internal heat is being generated by Rossi's device that varies with time, the feedback can be designed to keep the net thermal output constant.
I do not understand why you guys are concerned about the use of feedback. A well designed system is generally more stable than an uncontrolled one. For example, if the AC line voltage varies, the feedback can compensate for it. Do not let the use of negative feedback concern you. That is a non issue.

As Stephen Lawrence pointed out, the output power is stable and unvarying. That seems to rule out adjusting the heating drive elements. The power is not perfectly stable. - Jed
