would you use a rheostat/dimmer for flexwatt?

I'm not worried about maxing out the dimmer... I'm worried about the flexwatt getting way too hot. The problem is that resistive heating elements just keep on getting hotter and hotter even when the amount of power being applied is reduced (lamp dimmer) As a short term solution (a few weeks) it should be ok, but I cannot in good conscience recommend it as a long term replacement for a thermostat.

I have a degree in electronics, please explain this to me. if I can figure out how to make a resistive heating element to heat homes that will continue to get hotter with less power (wattage) you and I will become billionaires.
