Can I set my water heater to 125?
If you invest in one or more thermal protection devices to protect against overly hot water, the water heater could be safely set a little higher than 125 degrees. Most water heaters don’t have a thermostat control that is calibrated in such a way that you can just dial in 125 degrees.
What is the maximum temperature that the water heater should be set at so as not to scald?

Should I set my water heater to AB or C?
The Department of Energy recommends setting your heater to 120 degrees Fahrenheit. That should be plenty hot enough for most uses in your home. Now, some water heater temperature controls come with settings that read “A-B-C” as opposed to numbers.
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.
What should my hot water tank thermostat be set at?
A domestic hot water cylinder thermostat should be set at 60-65ºC. This is high enough to kill off harmful bacteria such as Legionella. If you set the thermostat much higher than this the water that comes out of the taps will be too hot and there’ll be a risk of scalding.
Is 117 degrees too hot for a bath?
The optimal temperature for shower water or bath water, so that it washes away environmental dirt and bacteria, is no higher than 112 degrees Fahrenheit, Cleveland Clinic dermatologist Melissa Piliang says.
What should hot water tank be set at?

Is 50 degrees hot enough for hot water?
So, what is the best temperature range for your water heater? The EPA recommends 120 degrees because it’s hot enough to keep diseases at bay, it’s not hot enough to cause scalding, it will supply enough hot water for most small families and is relatively energy-efficient.

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 is the maximum temperature setting of water heater temperature relief valves?
The standard opening pressure for TPR valves on residential water heaters is usually 150 psi. Most water heater tanks (cylinders, geysers, calorifiers) also have a standard operating pressure of 150 psi. The standard maximum temperature rating for a TPR valve is usually 210°F.
Is 120 too hot for water heater?
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.
