120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire’s disease.
Is 130 too hot for water heater?
Professionals recommend keeping your water heater set at a temperature between 130 and 140 degrees Fahrenheit. Any higher, or lower, could actually be dangerous for you and your family. While turning the temperature up higher can result in burns, turning it lower than the recommended setting can also be dangerous.
Is 150 too hot for water heater?
The recommended setting for household water heaters is not 150 degrees, but slightly less _ 140 degrees. Water temperatures higher than 140 degrees can burn the skin and are particularly dangerous for young children and the elderly.

What’s a safe temperature for water? On the side of most water heaters, you’ll find a warning that says water temperatures of 125 degrees Fahrenheit can cause burns or death. To be safe, the water coming out of the plumbing fixtures in a home shouldn’t be any hotter than 120 degrees.
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.
Does turning up water heater make hot water last longer?
When you raise the water heater temperature, the tempering valve will automatically reduce the volume of hot water in the mix to prevent scalding. Thus, the rate of consumption DOES depend on temperature. The lowered rate WILL make the hot water in the heater “last longer”.
What happens if water heater is set too high?
The Consumer Product Safety Commission (CPSC) recommends setting the water heater at no more than 120 degrees Fahrenheit (49 degrees Celsius) to prevent scalding. Not to mention, a water heater that is set too high can unnecessarily increase your electricity bill.
What is the temperature of water in 4 minutes?
Investigation: Take a cup of boiling water and measure its initial temperature. Then record the temperature of the water each minute for thirty minutes. Time Temperature 4 174 5 167 6 161 7 156.
What is the normal water temperature?

What temperature kills bacteria in water?
The World Health Organization (WHO) notes that bacteria are rapidly killed at temperatures above 149°F (65°C). This temperature is below that of boiling water or even a simmer.
What is the hottest water temperature a human can survive?
There also isn’t a way to confirm that 95 F is the exact wet-bulb temperature that’s unsurvivable; Raymond estimated that the true number is in the range of 93.2 F to 97.7 F (34 C to 36.5 C). Although no one can live at a wet-bulb temperature higher than about 95 F, lower temperatures can also be deadly.
Can your bath water be too hot?
The biggest risk concerns your skin. Bathwater that is too hot depletes your skin’s natural oils, causing it to dry out faster than it normally would. This can exacerbate skin conditions like eczema, rosacea, psoriasis, and sensitive skin.
How long should a 50-gallon water heater stay hot?
A 50-gallon hot water heater with 5,500-watt elements set to 120 degrees takes about 1 hour and 20 minutes to heat water coming in to the unit at 60 degrees. Conversely, when the water entering this same tank is 40 degrees, it takes 1 hours, 47 minutes to heat it up.
Why do I only have 10 minutes of hot water?
If you are getting less than a full tank of hot water, the most likely cause is the bottom element burning out. Less likely, either of the thermostats could be faulty, which could be keeping the lower element from turning on.

What is the maximum temperature that the water heater should be set at so as not to scald?
120 Degrees is the recommended max temperature for water heaters, according to both the American Society of Sanitary Engineering and the US Department of Energy. Firstly, setting the max temperature to 120 degrees prevents the water from scalding your skin.
Why is my hot water too hot?
If your water heater is making hot water too hot all of a sudden, it’s likely the result of the temperature setting being too high, a malfunctioning thermostat, high mineral content, or the pressure relief valve is blocked. Each of these issues can cause the water from the faucet to come out too hot.
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).
