Either heater will require a dedicated circuit. If you have a dedicated
circuit that is 120 volt, and it is a two wire circuit, there is no reason
it couldn't be converted to 240 volt.

The 110V models draw 12.5 A. If it is a 20A circuit in a powder room, you
can get away with a light or two as 16A load is allowable. No hair dryers
though.
