Will 115 degree water burn you?
Hot Water Safety. Even though a water temperature of 110° F is ‘relatively-safe’, exposure can be painful; the human pain threshold is around 106-108° F. A child can suffer a third-degree burn in 124°F water in less than three minutes. Children and adults can be burned this badly in two seconds or sooner in 149°F water.
Is 180 too hot for water heater?

Can water get to 400 degrees?
As the oven heats up, the temperature of the water will rise until it hits 212 Fahrenheit (100 degrees Celsius) and it starts boiling. If you let all the water boil away, the temperature on the thermometer will shoot up to 400 degrees Fahrenheit (232.2 degrees Celsius).
How hot is water just before boiling?
This conversion of liquid water to water vapor (steam) is what you see when you’re looking at a pot of boiling water. As we all know, for pure water at standard pressure (the air pressure that exists at sea level), the temperature at which this occurs is 212°F (100°C).
What is the temperature of boiling water after 30 minutes?
Thermal inactivation has been examined in water, sewage, milk and other liquids at temperatures close to those used for pasteurization (e.g. 63 °C for 30 minutes, 72 °C for 15 seconds) and in hot water (about 60 °C).
Is 117 degrees too hot for a bath?
