Abstract
A water heating and treatment system with UV lamp and anti-scale water treatment sanitation for suppression of pathogens including undesired bacterial content in a domestic water system includes a water heater. A cold water supply line to supply water to the water heater includes an anti-scale device, and a UV sanitation lamp. A water heater sanitation loop includes a sanitation loop pump to circulate hot water within the water heater. The water heater controller causes an activation of the water heater sanitation loop and a water temperature of the water heater to increase momentarily to a sanitization temperature above 151° F. for one or more periods of at least two minutes in a sanitation loop mode. A method for treating hot water to suppress pathogens including undesired bacterial content in a domestic water system is also described.
