Resistive losses are as square of current.

Running high current continuously through std 15a. plug is a fire
hazard.

For any sort of heater, you really want connections hard-wired. (Screw
terminal or such) IMHO.

The resistance of a 240V 1500W heat element is 4 times that of a 120V
1500W element.

Energy lost because of resistance becomes heat.

An electric heater is not 100% efficient (just close to it). Some of
the energy is lost as EM radiation (such as visible light).

BTW, a 99% efficient heater could be thought of as a 1% efficient
lamp.
