Dontcha just hate it when a tirade goes wrong?  

The transformer typically used with heating coils converts 110VAC to
24VAC, not DC.  Most transformers that I know of are AC to AC.  Of
course, there's that cool Transfomer that goes from an F-15 to an
Amazon Goddess, but that's probably off the subject. <g>
