The solution of using a heat exchanger to keep the water used in the 
house, in human contact, out of the plumbing system of the heater 
element, i.e. the plumbing and apparatus that is in direct contact with 
the source of heat, would probably work to prevent contamination of DHW 
with the pathogen.
