Furthermore, should it or should it not be inferred that the heater connection will be switched from a 240 V to a 120 V power line; [and if so] should the frequency of the power line remain constant or rationalize to its respective voltage?

I'm guessing that given that it would require much heavier and more expensive wire to distribute the power, the power per base-board remain constant.

The frequency would remain the same as it is usually a standard within a certain country,  U.S.A. being 60 Hz Europe 50Hz.  I think your guess for the heavier wire is probably a good one.
