This would seem to imply that a 110V ceramic heater could be used on higher
voltages ie: 220V ?? The higher the voltage, the higher the current = the
elements heat up more and the current drops accordingly.
Then the only problem would be the fan. What would happen if you put a 110V
60Hz fan on 220V 50Hz (other than the fact it will turn more slowly but have
more torque ?)
