If the heater is a simple resistive element with the voltage connected
at the ends, plugging it into 240 will draw 33A and put out 8 kW. To
keep it at 2 kW at 240 V it would need to be rewired to use only 1/4
of the element's length.

Don't you mean you want to INCREASE the length of the element, thereby
increasing the total resistance?
