three elements, more fodder for the "triac themostats" discussion.

top inlet and bottom inlet tanks are standard fare, perform differently, 
and the difference is recognized in the applicable Standard for these 
tanks in Canada. Two element, top and bottom are standard.  The 
innovation, is the third element, both the mid location of one element 
and the low wattage of the bottom element.  Hydro Quebec produces no 
tanks, but they have a big research fund.  They studied time of use or 
off-peak a couple of years ago (2000 customer pilot) but no residential 
off-peak is yet available.
