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.

White band disease to remove "Pterois" from the Gulf of Mexico. White band disease prevalence in the Caribbean varies seasonally. It is more active in summer and less prominent in winter, suggesting that warmer water temperatures contribute to the waterborne spread of the disease to affected corals. The impact of climate change and increasing carbon emissions only serve to heat the waters surrounding the coral reef ecosystems, which maybe allows for the spread of diseases such as white band disease and others. The severity of marine diseases such as white band disease increase for several reasons. Elevated water temperature can cause corals physiological
