Really? So they couldnt be recalibrated with a thermometer?

Damn....

You might be able to do that if the heating element used is
comparable in wattage to whatever they were designed to use. Most
heaters use nichrome wire, so the temperature coefficient would
probably be quite similar if the wattage were similar.

A little tinkering would tell that story faster than a whole lot of
conjecture.
