1- Normally for residential the water should not exceed 140 deg BUT many people like to keep the water about 125 Def F to prevent scalding 2- When the elderly or young children are exposed to hot water it is usually tempered to105 deg 3- For Commercial applications the water for a dishwasher wash is set 160 Deg F and rinse in lieu of chemicals is set 180 deg F for sterilization Water heated below 140 deg F will not kill bacteria and actually acts like an incubator for all types of water borne bacteria To hot if the piping is not designed properly will put a lot of stress as the coefficient of expansion per degree of temperature must be calculated in the design /install such as a four (4) fitting swing off the hot water riser.
