Here in NZ we have to have them at 55 Celcius - that's about 130 F. and like Steve said to prevent Legionnaire's disease. New installations have to have a anti scald fitting too. That's so if the thermostat goes whacky and near boiling water comes out it's diluted with cold to bring it back to 55 C.
