Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 Â°C (212 Â°F) and the critical temperature, 374 Â°C (705 Â°F). It is also known as subcritical water or pressurized hot water..
Incoming potable water temperature is assumed to be 50Â°F (10Â°C). For most uses, the water heater temperature setting is 120Â°F (49Â°C), but can be as high as 140Â°F (60Â°C). For an end use such as a shower, a typical temperature of 105Â°F (41Â°C) is achieved with a combination of hot and cold water.
