If domestic dishwashers are connected to the cold as directed by the manufacturer. And people use cold water washing powder in much larger quantities than hot water powder, why create a dual system in a domestic situation when Legionella is killed in the hot water system??

Homeowner, both tanks should be at greater than 66c to ensure no growth of legionella. (bet I’m a degree out, and get bitten for it

I have never seen a dish washer hoked up to a cold water line EVER, BUT I have seen a temperature booster (like a small boiler) to raise the temperature to the dish washer to germ killing temperature
