Water heating by a domestic water heater. Two conflicting safety issues affect water heater temperature—the risk of scalding from excessively hot water greater than , and the risk of incubating bacteria colonies, particularly "Legionella", in water that is not hot enough to kill them. Both risks are potentially life-threatening and are balanced by setting the water heater's thermostat to . The European Guidelines for Control and Prevention of Travel Associated Legionnaires’ Disease recommend that hot water should be stored at and distributed so that a temperature of at least and preferably is achieved within one minute at points of use.

Black pod disease hotter more dry times of the year. The disease has a spike shortly after a rainfall. The humid weather that is associated with this pathogen and all other black pod disease pathogens is needed as the sporangia forms and starts distributing spores through rainfall, splashing water, and running water. With this pathogen spreading behavior needing water is why there is almost always a spike in the prevalence of the disease shortly after the rainy season. The spread of infection to pods above bare soil was shown to be greater relative to pods above litter. The reason for this is due
