Legionella

Legionnaires’ disease is a lung infection you can get from inhaling droplets of water from things like air conditioning or hot tubs.

Heat water to 60 degrees to kill the bacteria, distribute it above 50C
they grow in water between 20-45C
they thrive more in polluted water: algea, rust, sediment, limescale
