I have a well insulated 35 x 12 shop that is attached to the house. I have a very old Arvin 1650/1300 watt 110v heater that will warm it up and keep it warm even if very cold outside. However I don't like to run it on the 1650 setting real long because it will heat the power cord up also.

You pay for kilowatt hours, and watts are watts, no matter what the voltage.
The efficiency of 220 over 110 is less loss from the heat of the wiring, as the wires get hot, the current resistance rises.
