Abstract

A device (100) for heat-treating water is provided, comprising a confined heating zone, a passageway (15) for transporting the water to said confined heating zone (23) so as to facilitate heating of the water, a controller (27) for preventing the heated water from leaving the device (100) until pathogens entrained in the heated water are killed; and an antimicrobial substrate (20) for preventing pathogens entrained in unheated water from leaving the device (100).
