   There's no problem adding a center tap so that they can drive each half   
   of the element in either series or parallel depending on the mains voltage.   
      
   (The problem with this is that other than hair dryers, most Europeans   
   expect way higher power heating appliances than can be powered by a 15A 120V   
   main and this method gives you the same heating capacity on either voltage).   
      
   Growing up we had a bunch of dual-voltage appliances like this.
