Hot Water Temperature: Avoid Setting Your Water Too Hot
If your hot water temperature is set to 140 degrees Fahrenheit, it takes three seconds to burn your skin serious enough to require surgery.Three seconds isn’t long at all.What’s more, The American Burn Association found that 41 percent of the homes they inspected were at unsafe levels capable of causing these types of significant burns to your skin.Imagine if your hot water temperature was set to 150 degrees of more.When the temperature of the hot water tank is too high, it may affect its service life.However, when the temperature is too low, legionnaires disease can develop.
Rule of thumb is safe bathing and showering temperature is 100 degrees Fahrenheit.That means your heater hot water temperature should be set at or below 120 degrees Fahrenheit.Sometimes water heater thermometers vary depending on the brand, the age, or how much the water heater is used.That means you should adjust your water heater to at or below 120 degrees Fahrenheit and then re-test it 24 hours later.
Water Heater Temperature
As recommended by the Centers for Disease Control and Prevention, water heater temperatures should not be higher than 120 degrees Fahrenheit.Because infants and small children have more sensitive skin than adults, they may require a lesser concentration of the product.If you keep the temperature of your water at 120 degrees Fahrenheit all of the time, you can almost prevent the possibility of serious burns and injuries.Using a meat thermometer near a water faucet with the hot water turned on will allow you to check your water temperature quickly and easily.Water heaters run continuously to provide you with hot water even when you are not using them.For those who live in a colder area, your water heater will work furiously to keep your water at 120 degrees Fahrenheit at all times.
Your energy cost may rise during the colder months of the year, which is when you’ll most likely notice it.They are variables that influence how your water is heated and how long it takes to maintain a 120-degree Fahrenheit water temperature.
Hot Water Temperature
The factors that influence the temperature of your hot water are numerous. They include everything from the sort of plumbing you have to the type of electricity you consume. Gas or electricity are the two types of energy. The criteria listed below provide insights on what sorts of items might have an impact on the temperature of your water heater.
- If your home’s faucets are located a great distance from your water heater, heat is lost during the transfer of water from the heater to the faucet. It is possible that you will lose even more heat if your pipes are not properly insulated. Occasionally, you may need to raise the temperature of your water heating system to more than the recommended 120 degrees Fahrenheit
- if you do raise the temperature of your water heating system above the recommended 120 degrees Fahrenheit, you will need to perform regular temperature checks at your faucet, so try to incorporate them into your schedule.
- The Centers for Disease Control and Prevention recommended that you keep your water heater temperature at 120 degrees Fahrenheit. OSHA has a separate recommendation for the temperature of hot water. The Occupational Safety and Health Administration (OSHA) recommends that you keep your water heater at 140 degrees Fahrenheit to limit your risk of exposure to germs and Legionella.
- Not only do different safety agencies have different guidelines for acceptable water temperature, but so do different health agencies as well.
You might be a little perplexed by the various water temperature suggestions. However, if you keep the temperature of your hot water between 120 and 140 degrees Fahrenheit, you will be within an acceptable and safe range. In addition, you must do routine monitoring of your faucet water to determine the temperature of the water.
Changing Your Water Heater Hot Water Temperature
Every hot water heater has a separate set of panels that regulate the temperature of the hot water.No matter what sort of water heater you have, the majority of the panels are the same and even positioned in the same general places.The majority of electric water heaters are equipped with two thermostats.Changing the temperature of your water heater may be found at: Changing the Temperature of Your Water Heater Water Temperature
Increase The Temperature To Eliminate Sulfur Smell
Many individuals raise the temperature of their water in order to kill microorganisms in the water.It is sometimes desirable to raise the water temperature to a degree high enough to kill germs and eliminate the rotten egg odor.The temperature of the water heater must be raised to at least 160 degrees Fahrenheit (71 degrees Celsius) in order to destroy the germs in the water supply.Beyond being harmful, a high temperature like this may cause medium and long-term difficulties in your house, as well as shorten the lifespan of your water heater.There are a variety of less hazardous methods for removing the sulfur smell from your hot water.The Corro-Protec powered anode will eliminate the rotten egg smell in as little as 24 hours, and there is no need to raise the temperature of the water heater during this process.
Hot Water Heater and Heater Component Replacement
Some firms provide core replacement parts for items like water heater anodes and other components in water heaters, which may be purchased online.Some of these businesses adhere to and even go above and beyond best industry standards and practices.It will also be done on a consistent basis with each and every work since they wish to strengthen industry rules.Heat traps, ignitors, powered anode rods, dry-fire protection, and other components of a hot water heater that may need to be replaced from time to time include, among other things, heat traps and ignitors.Others just assist you in making improvements to the warmth and safety of your hot water heater or its components.When you need to repair an anode rod, you’re changing something that is responsible for protecting the steel metal tank.
Save Money With Easy DIY
To maintain the energy efficiency of your water heater and to avoid scorching or a cold shower, you should empty your water heater at least once a year, according to the manufacturer. Because silt collection will impair the energy efficiency of your tank, you will spend more money to heat the same volume of water as a result of this.

Please keep in mind that this content may contain affiliate links.This means that, at no additional cost to you, we may gain a small profit on purchases made via our links.In the event that you have already adjusted the temperature and are complaining to yourself that you ″have no hot water″ or ″don’t have enough hot water,″ there are a few reasons that might be impacting the heat.If all else fails, it’s possible that the heating element is faulty and has to be replaced.
How To Check Your Water Heater Temperature
The majority of water heaters do not have a temperature gauge with a digital readout on them.A temperature or heating range is marked on the thermostat, rather than a number.A cup and a culinary thermometer will be required in order to correctly determine the temperature of the hot water heater.If you haven’t used your water heater in at least one hour, turn on the faucet that is nearest to it.Allow the water to run for at least one minute to ensure that the water is at its warmest possible temperature before filling the cup with it.Insert your cooking thermometer and make any necessary adjustments to the temperature settings.
Recommended Temperature Settings
Water heaters are pre-programmed to operate at temperatures about 140 degrees Fahrenheit, which is recommended by OSHA.The Environmental Protection Agency, on the other hand, recommends lowering the thermostat down to 120 degrees Fahrenheit to save power use and using a booster heater to attain sanitizing temperatures at certain outlets.Another point of view is that lower temperatures are preferable for homes with little children, although higher temperatures are more effective in cleaning and sanitizing surfaces.Recommendation from me Personally, I feel that the temperature of a water heater should be set around 130 degrees in practically all circumstances.However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.
How To Turn Up Your Water Heater
If you are dissatisfied with the suggested temperature of your hot water heater, you may alter the settings to receive extra hot water.Although electric water heaters may require a screwdriver and potentially a tiny wrench or socket, most hot water heater settings are straightforward to modify.Keep in mind that the thermostat is factory configured to a recommended temperature, and that altering the setting may increase the risk of significant burns from the appliance.
How to Set Temperature on a Gas Water Heater
- The temperature of a gas water heater may be adjusted by turning the setting knob on the water heater. The majority of gas control valves have a knob with different designations on them, such as A-B-C. Control valves for gas water heaters may be labeled differently depending on the manufacturer. In the majority of circumstances, the following is what each label indicates: Temperatures range from 80-90 degrees
- hot (or triangle sign) = 120 degrees
- A = 130 degrees
- B = 140 degrees
- C = 150 degrees
- Very Hot = 160 degrees
There is a ″Vacation″ setting that appears from time to time. This does not heat the water, but it does ensure that the pilot light remains lit.
How to Set Temperature on an Electric Water Heater
Turn off the circuit breaker if necessary. Remove the access panels from the room. Under the insulation, look for the thermostat adjustment screwhole. Adjust the thermostat control to the appropriate temperature by using a straight screwdriver to make the adjustment. After replacing the insulation and panels, the power should be restored. Here’s a good video that demonstrates the procedure:
Factors That Affect Water Temperature
Some of the things that may influence the temperature of your hot water include the distance between the water heater and the outlet, the way the pipes are built, and the quality of the heating element itself, among others.Because of the length of the pipe and the small bore size, it will take longer for the hot water to reach the opening.Additionally, pipes that run beneath or outside the residence may be exposed to freezing or freezing temperatures in the winter and summer.If you have a big house, you may want to consider installing a hot water recirculation system, which may reduce the amount of time it takes to send hot water to all of the outlets in the house, as well as provide significant cost savings over time.If setting the thermostat does not result in the desired temperature, it is possible that the water heater element has to be replaced.Alternatively, if you don’t notice a difference in water temperature after changing the thermostat, it’s likely that you have a malfunctioning thermostat that has to be replaced.

Setting the Ideal Hot Water Heater Temperature
Are you tired of burning your hands every time you turn on the hot water in the shower?What if you’re having trouble getting a comfortable water temperature, no matter how high you turn the faucet up?These are not always indications that your water heater is malfunctioning, but rather that the temperature setting you have chosen is not optimal for your purposes.A water heater that has been installed incorrectly can have a significant influence on your life, even in areas that are not directly linked to your plumbing or heating system.In the case of a water heater, which consumes around 18 percent of the energy in your house, changing it by just 10 degrees can result in a three to five percent reduction in your monthly energy bill.It can also have a negative influence on your health or the health of people who share your home with you.
How do you set your thermostat when there is so much riding on the outcome?A definitive or simple response cannot be given; rather, part of it is a matter of personal choice.But there are a few guidelines you may follow to ensure that your temperature setting is optimal for you.
General Recommended Water Heater Temperature
You can find out what temperature water should be at by visiting the Environmental Protection Agency.The optimum temperature is 120 degrees Fahrenheit.You will really save money because your water will not be hot enough to cause scalding, most small households will have adequate hot water for their needs, and reheating will not need an excessive amount of energy consumption, allowing you to save money on your utility bills.This temperature, on the other hand, is not ideal for everyone.Some homes will require it to be even hotter than this for a variety of reasons that we shall address shortly, but exercise caution when exceeding this temperature threshold.
Considerations When Choosing a Water Heater Temperature Setting
Do you have any at-risk individuals residing in your home?Those who are particularly sensitive to high temperatures may suffer serious consequences if they are exposed to overly hot water.It only takes two seconds of exposure to water at 150 degrees Fahrenheit to create third-degree burns in small neonates, and only five seconds at 140 degrees to cause third-degree burns.Temperature reduction is more safer for your infant and far more cost-effective in terms of energy use.A water heater set at no more than 130 degrees is recommended if you have a baby or any youngster under the age of three in your household.Elderly homeowners should follow the same guidelines and laws as everyone else, because they are also at risk of burning quickly and suffering potentially painful injuries if they are accidentally exposed to too hot water.
Those who have compromised immune systems or who suffer from respiratory ailments, on the other hand, may benefit from a hotter water temperature in order to destroy bacteria while also increasing the concentration of steam in the air when bathing.When dealing with these people, and assuming there are no smaller children around, we recommend keeping the water temperature no higher than 140 degrees.Do you have an appliance that is energy efficient?Dishwashers that pre-heat are becoming increasingly common.Essentially, these systems take in water and then raise the temperature to even higher levels to provide an even better and more hygienic clean, all without the need for you to raise the temperature coming from your water heater.
When it comes time to update or replace your dishwasher, we strongly advise you to search for one that has a pre-heat system built into it.If, on the other hand, it won’t be for a long time, you may wish to raise the temperature of your water heater to 140 degrees.It is possible to maintain the water nice and hot for your dishwasher while still keeping it safe to use for the majority of your family members if you use enough cold water to compensate for the hot water.How many people do you have living in your house?While everyone has their own temperature preferences while bathing, you can typically fine-tune them with the hot and cold water knobs on the shower head.
Those who like a hotter shower increase the ratio of hot to cold water in their shower.Showers that are chilly to the touch are preferred by those who prefer them that way.The temperature of the water that comes out of your water heater, on the other hand, will have an impact on this as well.
The hotter the water that comes out of your heater, the less hot water individuals will require, and the more cold water they will need, to attain their preferred temperature.People that use cooler water heaters will require more hot water and less cold water in order to achieve their goals.As a result, people who adjust their water temperature to a lower setting will find themselves running out of hot water more quickly.If you have a large home with multiple people living in it, you should raise the temperature of the water to ensure that your hot water supply lasts as long as possible.
- Smaller homes with fewer occupants may get away with setting the thermostat lower since they are less likely to run out of heat in the first place.

What Temperature Should a Hot Water Heater Be Set at?
What temperature should a hot water heater be set at?Do you have the same question as many other people?Setting the water heater to the proper temperature is critical for providing not just more pleasurable showers, but also longer showers.It also protects individuals from contracting infections.This page provides answers to your most often asked questions about the optimal hot water temperature.We’ll also go through some of the considerations you should keep in mind while adjusting the heater’s thermostat.
Let’s get this party started.
What is the Ideal Temperature Setting of a Water Heater?
There are two schools of thinking that can throw light on the topic of what temperature should be set for a water heater.Water heater manufacturers set the temperature of their water heaters to 140 degrees Fahrenheit by default, believing that the temperature is more calming and pleasant for the majority of people.According to the Occupational Safety and Health Administration, this water heater setting should be used to prevent the growth and multiplication of Legionella and other dangerous germs in water heaters.According to the Mayo Clinic, Legionella bacteria may be found in both water and soil as non-infectious agents that do not cause disease.In contrast, when these bacteria multiply in water systems, such as those found in air conditioning units and household plumbing, they have the potential to become harmful.People become infected with Legionella bacteria when they inhale water droplets containing the bacteria when showering or utilizing whirlpools, hot tubs, water heaters, or hot water tanks.
Alternatively, the United States Department of Energy and the Environmental Protection Agency have determined that the optimal water temperature is 120 degrees Fahrenheit (or below).Medical and healthcare professionals have also chimed in on the controversy, advising that the hot water heater temperature setting should not be lower than 120 degrees Fahrenheit in order to avoid microbial development in the water heater.The position of the Consumer Product Safety Commission, which recommends a maximum water temperature of 120 degrees Fahrenheit for safety reasons, further complicates the situation.According to the organization, hot water (over 120 degrees Fahrenheit) might induce burn injuries in persons who are vulnerable to them.The recommended temperature of 120 degrees Fahrenheit is likely to be appropriate for most people’s households.
Unfortunately, no two families or homes are comparable in their characteristics.As a result, it would be wise to analyze the role that various components play in the overall equation.
What Factors Should You Consider When Setting the Water Heater’s Thermostat?
People have varying opinions on what temperature hot water should be at the optimal time of day. It’s possible that I favor 120 degrees, while you or other individuals could prefer 130 or 140 degrees. Regardless of the sort of water heater you have, it is recommended that you take the following aspects into consideration.
In accordance with the American Burn Association, children under the age of 16 account for 26 percent of all admissions to burn treatment facilities.According to the organization, younger children are more susceptible to scorching injuries because of their weak cognitive and physical abilities, as well as a lack of parental supervision when using hot water, among other factors.Young children also lack the ability to perform self-rescue maneuvers.Because of pre-existing medical issues, slower response time, and decreased mobility, the elderly are particularly vulnerable to hot water-related burn injuries.In addition, as compared to other age groups, both children and the elderly have smaller skin layer thicknesses.Even when exposed to hot water for a short period of time or when the water temperature is modest, they might sustain severe burn damage.
According to the American Burn Association, three seconds of exposure to 140-degree Fahrenheit water is all it takes to create major burn injuries that necessitates surgical intervention.Because of this, you could believe that a hot water heater setting of 140 degrees Fahrenheit is safe for you.You must, however, lower the temperature in your home to 120 degrees Fahrenheit if you have children or elderly members of your household.
Immune System Functioning
We require a properly functional immune system in order to defend ourselves against infections.Whenever an organism infiltrates our body, the immune system mobilizes an army of defense cells to combat the invasion.Because immune-compromised individuals no longer have a powerful defense army in their bodies, they are more susceptible to infection than the general population.Increased water temperatures may be required to destroy germs in those who have lowered immune system capabilities.People who use immunosuppressive drugs are unable to protect themselves against infections.In addition to corticosteroids, monoclonal antibodies and biologics, and calcineurin inhibitors are examples of immunosuppressive medications.
People suffering from HIV/AIDS, psoriasis, Crohn’s disease, rheumatoid arthritis, and lupus are all affected in the same way.Patients undergoing organ transplant procedures also have compromised immune systems, which makes them more susceptible to infection than the general population.In houses with immunocompromised individuals, 140 degrees Fahrenheit is the best temperature for domestic hot water to be provided.While certain bacteria are thermophilic or heat-resistant, the vast majority of them cannot endure temperatures beyond 140 degrees Fahrenheit.Even the deadly Legionella bacteria will perish at 122 degrees Fahrenheit (50 degrees Celsius).
Unfortunately, certain heat-resistant viruses must be inactivated at temperatures greater than 140 degrees Fahrenheit in order to be killed.Families with immunocompromised individuals should adjust the water heater temperature to 140 degrees Fahrenheit, regardless of the reason.
According to the United States Department of Energy, adjusting the water heater to 120 degrees Fahrenheit can result in yearly energy savings ranging from 4 percent to 22 percent.It is estimated that the savings will come from lower demand losses (at least $400 per year) as well as lower standby losses (between $36 and $61 per year).When it comes to your water heater, if you are concerned about your power costs, you may want to keep the temperature no higher than 120 degrees Fahrenheit.Naturally, if money is not an issue, you may always raise the temperature to 140 degrees Fahrenheit on a regular basis.Once again, I strongly advise you to take into account the age and immunological health of your family members while determining the optimal water heater setting.
Water Appliances’ Energy-efficiency
The ″water preheat″ function on some dishwashers does not allow customers to adjust the temperature of the water heater’s thermostat setting to a more comfortable level. Those who own such a dishwasher are compelled to set the water heater to 140 degrees Fahrenheit as a matter of necessity.
- When it comes to the topic ″what temperature should a hot water heater be set at,″ you have two options. Turn down the temperature of your water heater to 120 degrees Fahrenheit if you want to save money on electricity or if you have elderly or young children in the house.
- If you have members of your household who are immunocompromised or if you don’t mind spending a huge power bill, set the water heater’s temperature to 140 degrees Fahrenheit or higher. If you have a dishwasher that does not have a preheat feature, you may additionally require this option.
Understanding the numerous elements that influence hot water temperature is essential to determining the optimal temperature.
What Temperature Should a Hot Water Heater Be Set at?
How many of you are aware of the fact that the common hot water heater temperature setting is typically 140 degrees Fahrenheit?In most cases, water heater manufacturers specify this value as the default value.This temperature level will aid in the prevention of the spread of Legionella bacteria in your household water supply.The question is, at what temperature should a hot water heater be set?Temperatures between 120 and 140 degrees Fahrenheit are recommended for your heater, since these temperatures will eliminate bacteria in your water, according to professionals.Furthermore, the optimal water heater temperature is determined by a variety of parameters, which I will address in greater detail later in this post.
Hot Water Temperature Levels Recommended by Professionals
What temperature should you set your water heater to?A minimum water temperature of 140 degrees Fahrenheit is required for larger residential systems, according to the Occupational Safety and Health Administration (OSHA).Smaller systems, on the other hand, require temperatures of at least 130 degrees Fahrenheit.This setting will produce 120 degrees Fahrenheit faucet or tap water temperature, which is the appropriate temperature for home hot water.The Centers for Disease Control and Prevention (CDC) and the United States Environmental Protection Agency (EPA) have determined that 120 degrees is the maximum acceptable hot water temperature (EPA).A hot water temperature of 120 degrees Fahrenheit is sufficient to keep infections at bay while also allowing for long, steamy showers to be enjoyed.
It will also have a positive impact on total energy and power usage.The CPSC (Consumer Product Safety Commission) recommends that customers set their water heater’s thermostat to 120 degrees Fahrenheit to avoid scorching, even though the maximum temperature for most water heaters is 150 degrees Fahrenheit.The skin of youngsters and the elderly is more sensitive to burns when exposed to hot water because their skin is thinner and burns more quickly.Furthermore, after two seconds of exposure to 150-degree hot water, the majority of children will suffer from a 3rd-degree burn.At 131 degrees Fahrenheit, a kid can be scalded in less than 4 seconds if the temperature is maintained.
Consequently, children should constantly be monitored to avoid unintentional water burns caused by playing with the faucet temperature settings when they are young.The majority of scalding burns in children occur as a result of an accident, which is why parents are inclined to lower the temperature of the water heater.Anything lower than 120°F, on the other hand, will not provide you with an additional layer of protection against the potential multiplication of Legionella and other bacteria in your drinking water.Although you have the ability to customize the temperature of your water heater to your liking, it is critical to be conscious of your water heater consumption habits in order to safeguard your family from the harmful consequences of improper temperature management.
Factors That Affect Hot Water Heater Setting
There are a variety of things that influence how we set the temperature of our water heating system. The following factors will assist you in determining the optimal heat level:
1. Households With Elderly People and Children
As previously stated, elderly people and children have thinner skin than younger youngsters and are consequently at greater danger of scorching.According to reports, children as young as 4 years old are admitted to hospitals with burn-related ailments, including scald burns and contact burns.In the meanwhile, reports of old or vulnerable persons suffering from burn injuries or infections are extremely rare in the media.However, as a precautionary measure, we must continue to monitor that the water heater’s temperature does not exceed 120 degrees Fahrenheit.Although there is one exception to this rule, it is worth mentioning.For those who have an immunocompromised member of the family, it is recommended that you increase your unit’s temperature to 140 degrees Fahrenheit, as recommended by the Department Of Energy.
2. Household Size
If you live alone, you might expect to have a lower water use.As a result, the vast majority of single inhabitants would most likely adopt a lower temperature to preserve energy.Lowering the temperature of the water heater to 120 degrees Fahrenheit might help you save up to ten percent on your water heating bills.In a typical residential house or apartment, a person can consume 20-35 gallons of water each day.However, because of the increased need for hot water in a big home, a higher hot water temperature may be preferred.
3. Pipe Size
What is the impact of the domestic pipeline system on the hot water consumption of your family?Increases in both flow rate and pressure are associated with decreasing internal diameter of the pipe.When using a tiny bore pipe system, it will take a long time for hot water to reach your faucets, as an example.As a result, heat will evaporate throughout the journey.If you have a bigger home or property, you should consider building a hot water recirculating system so that hot water can be delivered to your plumbing system more quickly and efficiently.It also implies that you will no longer be required to operate at a high temperature all of the time, resulting in a significant reduction in energy use.
4. Non-Preheat Dishwasher
The majority of modern dishwashers nowadays are equipped with pre-heating technology, which boosts the temperature of the incoming water before it is used. The water heater should be heated to 140 degrees Fahrenheit if your dishwasher does not warm the water before use. This will provide the appropriate sanitizing temperature.
5. Ambient Outdoor Temperature
The temperature level at which we should set our water heater is heavily influenced by the weather conditions outside our home.It is possible that your hot water production will be affected by the unpredictable weather outdoors.For example, during the winter months, the water that enters your pipes will be cooler than during the summer months.As a result, your heater will have to work more as a result of this.
5 Quick and Easy Energy-saving Tips for Water Heater
1. Lower The Temperature On The Thermostat
We may save anywhere from 12 to 30 dollars each year for every 10 degrees we lower the temperature, according to a Department of Energy research.
2. Reduce Hot Water Usage & Insulate Water Tank
When doing actions that do not necessitate the use of warm water, such as brushing your teeth, it is more effective to switch off the water heater.Additionally, a lack of insulation might result in the consumption of additional energy.If your water heater’s tank is not properly insulated, it will cool more quickly.As a result, it will take a long time for the entering cold water to be converted into hot water, particularly if the weather is very cold.
3. Insulate The Water Heater Pipes
It is necessary to insulate the hot water pipelines in addition to the tank since doing so will assist to decrease standby heat losses and will protect your tank from bursting, which can be caused by freezing conditions. Because you won’t have to switch on your water heater as frequently as you would otherwise, this added protection will help increase the longevity of your water heater.
4. Inspect And Repair Leaky Valves
A leak in a water heater is a common problem that most homeowners have to deal with. The majority of the time, excessive water pressure is the source of the leakage. This is not a problem to be taken lightly, as it has the potential to harm the water heater and waste more than 90 gallons of water every day.
5. Drain Sediment From The Tank
Tank drainage should be performed once every six months since sediment buildups tend to accumulate at the bottom of the tank and increase the heater’s power usage.
‘What temperature should I set my hot water heater to?’ is a question that many people have.I hope you’ve gotten a better grasp of how to correctly manage the temperature of your own water heater as a result of this article.Being aware of when to increase the temperature on your thermostat can help to decrease the risk of scalding and microbiological contamination.Is there anything more you’d want to know about your hot water system?Fill up the blanks with your thoughts in the comment section below.
What Temperature Should a Water Heater Be Set At?
Where Should a Water Heater Be Set?What Temperature Should a Water Heater Be Set At?One of the many probable flaws that a home inspector would look for is an increase in the temperature of the water heated by the system.Temperature settings on water heaters that are either too high or too low might be dangerous.Let us first consider the issues that might arise as a result of excessive water temperature fluctuations.
Hazards of an overly-high setting:
The higher the temperature setting, the greater the amount of energy used.The elderly and tiny children have thinner skin and are more prone to burning than the general population.A infant can acquire third-degree burns from 150-degree water in two seconds, and 140-degree water in five seconds, if exposed to these temperatures.Households with elderly or small children may find that setting the thermostat to 120 degrees is the most safest option.As youngsters get older, it may be essential to raise the temperature if necessary.
Hazards of a too-low setting:
Water temperatures below 120 degrees can encourage the growth of hazardous bacteria, including the potentially lethal Legionella bacterium.It is recommended that those with impaired immune systems or respiratory diseases set their thermostat to a temperature of 140 degrees.Dishwashers should use water that is at least 140 degrees Fahrenheit in order to thoroughly disinfect.Most new dishwashers include built-in water pre-heaters that can raise the temperature of the water if necessary, so you won’t have to heat your water to 140 degrees as often as you might otherwise.Older dishwashers, on the other hand, may not have a built-in heater.
Annoyance / Inconvenience
Bathing or showering with water that is not hot enough when it leaves the water heater may be uncomfortable due to the fact that the water cools as it travels through the plumbing system. Tank-type water heaters with their temperature settings set too low will also run out of accessible hot water more quickly.
How To Check and Set Your Water Heater Temperature
The heating element assembly of these heaters has one or two thermostats, which are integrated into the design.Here is a link to a guide on how to do it.The temperature of these heaters may be readily controlled by turning the adjustment knob, which is often positioned at the bottom of the heater.A digital control on the machine or a remote control are often used to make these adjustments.You may check the temperature using a cooking or meat thermometer that has been submerged in a stream of hot water..
What Temperature Should a Hot Water Heater Be Set At?
Previous Post Next Post Your water heater accounts for around 18 percent of the total energy consumed by your home.If the temperature of your water heater is set too high, you will be forced to pay the price in your monthly energy bill.The converse is true: if you have your water heater set too low, your water may not get hot enough (resulting in short showers), or worse, it may get contaminated with germs.Maintain a 120-degree temperature for your water heater at all times because infections can form in the stagnant water within the water heater, notably Legionella, which is extremely deadly.How can you determine what temperature range is most appropriate for your water heater?In addition to being hot enough to keep viruses at away while not being scorching hot enough to cause blistering, 120 degrees will provide adequate hot water for most small households while still being relatively energy-efficient, according to the Environmental Protection Agency.
However, depending on a few criteria, the most appropriate setting for you may differ.
Factors That Affect Hot Water Temperature Setting
- These criteria are unaffected by the kind of piping you have (PEX, PVC, or copper), the method of heating the water (gas or electric), or even if you have a tankless hot water heater installed. Owners of dishwashers that do not pre-heat the water may wish to set their water heater temperature to 140 degrees
- elderly or families with young children may want to keep the temperature at 120 degrees. In the words of BabyCenter.com, ″It takes just two seconds for a kid to acquire third-degree burns from water that is 150 degrees, and five seconds if the water is 140 degrees, the temperatures at which hot water heaters are frequently sent from the factory.″
- It is recommended that the hot water temperature be maintained at 140 degrees in homes with people who have a compromised immune system or respiratory problems.
- Because there is less demand for hot water and hence less money spent on hot water, many people who live alone prefer a lower temperature within an acceptable range. When it comes to those who live in big households, many choose a higher temperature in order to handle the increased need for hot water.
- In order to save money, every 10 degrees you lower the temperature of the water tank thermometer results in a 3 to 5 percent reduction in your energy bill.
Are you still undecided? To begin, set the temperature to 120 degrees Fahrenheit and gradually raise it in small increments until you reach the desired shower temperature.
What’s Your Current Temperature Setting?
You can find your current temperature setting by looking at the dial on the water heater (if equipped) or taking a temperature reading from the faucet. Turn on the hot water tap and allow it to run for a few minutes before taking the temperature.
Solutions to Common Hot Water Tank Problems
If you’re concerned about pathogens in your hot water, as well as the possibility of scalding water, you might consider installing a hot water tank booster.This allows you to maintain your water at 140 degrees in the tank while mixing it with cold water to bring the temperature down to 120 degrees before it reaches the faucet.Having a hot water circulating system installed in your home might alleviate the problem of waiting for hot water to reach the faucet in a large household.This method circulates hot water slowly through the pipes in order to prevent it from cooling down before it reaches the faucet.

What’s The Best Water Heater Temperature Setting?
- A hot shower may receive a bad name from your dermatologist since it might dry up your skin, but many people like it for its relaxing properties! In a household where hot water is fiercely competed for among family members, or even between your washing machine and dishwasher, you may be tempted to raise the temperature of your hot water heater. But at what point does it become too hot? There are differences of opinion between the Department of Energy and the industry. Scalding can occur at temperatures below 120 degrees Fahrenheit, although 140 degrees Fahrenheit is the normal default temperature. Any temperature below 120 degrees Fahrenheit, according to the majority of experts, increases the likelihood that germs from stagnant water, such as the bacterium legionella, which causes Legionnaire’s disease, would form within your water heater. Whatever temperature setting you choose, it’s vital to remember that the kind of pipe used, how the water is heated (gas or electric), and whether your system is tanked or tankless have no effect on the temperature you choose. There are, however, a number of elements to take into consideration when determining your thermostat setting: Stick with 120°F if you have small children and/or the elderly in your house who are prone to third-degree burns in seconds, or if you are a single occupant owing to the decreased demand for hot water in your home.
- Consider 140°F if you have an immunocompromised individual in your home, a dishwasher that does not pre-heat, or a multi-occupant household owing to the increased need for hot water.
But what about the expenses of energy?We get what you’re saying!Water heaters account for around 14-18 percent of the total energy consumed by a residence on a typical day.Furthermore, it may be tempting to lower the temperature in order to save money.It should be noted that a 10°F decrease in temperature is related with a 3-5 percent reduction in energy use.Legionella, on the other hand, can live at temperatures as high as 122°F.
So make sure to strike a balance between your risk tolerance and your energy consumption targets!If you’re still on the fence, play around with it.Many hot water heaters are equipped with a temperature control dial.If yours does not, run the water for a few minutes and use a thermometer to check the temperature of the water thereafter.Start with 120°F and gradually increase the temperature in small increments until you get your desired result.
All things considered, it is possible that your house is not as simple as ″simply″ setting a temperature and forgetting about it.A water tank booster may be an appropriate option in houses where the requirement to maintain a greater hot water temperature for health safety must be balanced with the need to reduce the danger of scorching.To inhibit pathogens from growing in your tank, it retains the temperature at 140°F while mixing with cold water to provide a lower temperature at the faucet.Alternatively, you could live in a house where, no matter what temperature you select, hot water takes an inordinate amount of time to reach the faucet (or a certain tap farthest from the hot water heater).A hot water circulating system circulates hot water gently through the pipes so that you are not forced to wait.
Whatever you choose, we’re only a phone call away if you’re having issues with your hot water!
Setting your water heater’s temperature for best results
Time required for reading: 2 minutes It’s possible that you don’t give your water heater much thought, but it actually plays a very crucial role in the plumbing of your home.In addition to higher power expenses, a malfunctioning water heater might result in water that is either scorching hot or ice cold.It is critical to plan annual maintenance to verify that your device is clean (hard water build-up can be detrimental to your water heater) and that the temperature range is within acceptable parameters.Save money, extend the life of your water heater, and safeguard the health and well-being of you and your family by following these simple guidelines.Set your water heater to the optimal temperature, which is between 130 and 140 degrees Fahrenheit, according to industry professionals.If you go much higher or any lower than this, it might be harmful for you and your family.
While increasing the temperature over the suggested setting might result in burns, decreasing the temperature below the recommended level can also be hazardous.Bacteria can grow in the water heater tank when the water is cooler than the ambient temperature.This might become a health danger for you and your family, putting you and your loved ones at risk of contracting diseases such as Legionnaires’ illness.This condition is a sort of pneumonia, and the bacteria that causes it may grow in a water tank with temperatures ranging between 77 degrees and 113 degrees Fahrenheit, depending on the temperature.Check the temperature of your water heater.
You should contact a plumber if you are concerned that your water heater is set at an inappropriate temperature — either too high or too low — since they will be able to simply verify the setting with a specific thermometer and make any adjustments that may be necessary.The presence of sediment accumulation and calcification in the hot water tank itself will also be checked by a professional if the temperature on the water tank has been changed but you are still experiencing the same water temperature as you were before the temperature adjustment.If you hear hissing or sizzling noises in the tank, this is another indicator that sediment has accumulated.After draining the tank, a professional can attempt to address the problem by scraping off any scale that may have built up over time and soaking the components in hot water.Water heaters have a rather long life expectancy.
The average lifespan of a hot water heater is predicted to be between 8 and 12 years.It is recommended that if you have a water heater that is 10 years or older and looks to be leaking or having some problems operating, that you consider replacing it rather than simply performing a repair that will only temporarily cure the problem.Water heaters require regular maintenance.
Maintaining your water heater on a regular basis, like you would any other equipment, may go a long way toward prolonging the life of your water heater and maintaining it in excellent operating condition.If you want to ensure that your water heater continues to function effectively, you may want to consider hiring a professional to perform this maintenance.Maintaining your water heater’s temperature between the appropriate ranges is essential.This will prevent any bacteria from growing in the cold water and will protect you from being scalded by a shower that is much hotter than you anticipated.
Hot Water Safety
The human pain threshold is around 106-108 degrees Fahrenheit, therefore even though water at 110 degrees Fahrenheit is considered ″pretty safe,″ exposure can be uncomfortable because the human pain threshold is approximately 110 degrees Fahrenheit.As the chart below illustrates, the degree of a burn is determined by the temperature of the water, the length of time it was exposed to it, and the state of the skin.When compared to adults, children and the elderly have thinner skin and so suffer more serious burns in a shorter period of time and at lower temperatures than adults.In less than three minutes, a youngster can suffer a third-degree burn when submerged in water that is 124°F.Children and adults can be severely burnt in as little as two seconds or less in water that is 149°F.The fact that this graphic demonstrates how rapidly third-degree burns, the most deadly type of burn, can occur should not be overlooked.
These burns result in substantial tissue damage and have the potential to cause severe deformity, deformities, loss of function, and even death if not treated immediately.Moreover, first and second degree burns occur considerably more quickly, and when large sections of the body are affected, they necessitate the prompt and expert medical treatment that is required.
Estimated Times/Temperatures Causing a Full Thickness (3°) Burn in Adults/Children
|Water Temperature||Adults (skin thickness of 2.5 mm)||Children 0-5 Years (skin thickness of 0.56 mm)|
|<149°F||2 seconds||0.5 seconds|
|<140°F||5 seconds||1 second|
|135°F||10 seconds||4 seconds|
|<130°F||35 seconds||10 seconds|

Facts and Recommendations
- Domestic water scald injuries are the second most prevalent cause of major burn injuries in people of all ages, according to the American Burn Association. Every year, over 112,000 people are treated in hospital emergency departments for scald burns, with approximately 6% of those patients being admitted to the hospital. Young children, the elderly, and those with physical disabilities account for around 80% of all hot tap water burns. A large number of scaldings are the consequence of water heaters being set at temperatures higher than 120 degrees Fahrenheit. A variety of factors can result in scald-type injuries, which is regrettably true. There is no one solution or combination of devices that can protect all users. As a result, you should consider the following advice when designing hot water systems to assist prevent the likelihood of such accidents occurring: Large amounts of hot water at a variety of temperatures may be required in institutional and commercial establishments, for example. Water is frequently heated to extremely high temperatures, which are required for sanitizing and other procedures. It is also necessary to raise the temperature of the water heater in an effort to avoid bacterial development in the water distribution system. These temperatures are dangerously high for human contact, and they should be appropriately segregated or managed to prevent them from entering the distribution pipe that supplies plumbing fittings.
- Specify thermometers that are conveniently accessible and readable at key points throughout the system to enable for temperature monitoring. Provide thermometers at the very least at each heater discharge, at the master mixing valve outputs, and at the suction of each circulating pump.
- High-temperature alarms on the discharge of water heaters and master thermostatic mixing valves should be considered if the water temperature rises above 120 degrees Fahrenheit. Solenoid valves on the discharge of water heaters and master thermostatic mixing valves should also be considered because they will shut off the hot water supply if the set temperature is exceeded.
- It should be specified that all of the plumbing supplying master mixing valves should be fully cleansed before being connected to the TMV
- Prescribe that the installation, startup, and commissioning of all master mixing valves be validated and authorized in writing by a manufacturer’s representative who has received appropriate training
- Specify that the valve handle to open the bypass of temperature control devices be removed or otherwise secured in the closed position when a bypass of temperature control devices is supplied to enable repair work.
- Consider installing thermostatic control devices at each hot water fixture outlet, which will shut off the flow of hot water when the temperature rises to a level that is dangerously close to scalding. This provides an extra layer of protection against high water temperatures, even if the system that was initially installed has been modified.
- If a system of temperature-regulating equipment is not properly controlled and maintained, it will not perform efficiently, no matter how comprehensive or complex the system is designed to be. Provide your clients with information on how to properly operate and maintain the systems you develop. The following are a few ideas that you might want to think about making: In order to ensure that hot water systems are running effectively and in excellent condition, they should be subjected to regular inspections. The facility’s operations team should be educated on system design and how to identify warning signals of a problem.
- Instructions should be provided on how to report any instances in which the water coming from plumbing fixture outlets is excessively hot for comfort or safety. Ascertain that a member of staff is assigned the responsibility of frequently testing and documenting the temperatures in each tub and shower while just the hot water faucet is turned on. The discovery of water coming from a tap that is accessible to consumers that is hotter than 110°F should prompt an examination by maintenance professionals to modify or repair the system.
- Ensure that only authorized personnel have access to open bypass valves on temperature control devices
- likewise, ensure that only authorized personnel have access to change temperature control devices.

Children at risk for accidental burns from hot tap water
- PMID: 7997963
B E Pichoff and colleagues, Tex. Med., November 1994.
HTW temperatures should not be set higher than 49 degrees Celsius, according to the American Academy of Pediatrics, which identifies young children at risk for unintentional hot tap water burns (120 degrees F).An extreme temperature of 52 degrees Celsius (125 degree Fahrenheit) may produce a complete skin burn in 2 minutes, while an extreme temperature of 54 degrees Celsius (130 degree Fahrenheit) can induce a complete skin burn in 30 seconds.To determine the likelihood of HTW injury and the level of awareness about safety restrictions on our military base, we conducted a survey.Sixty family dwelling units were chosen at random for the purpose of measuring the temperature of the hot water heater using both an electronic thermometer and a mechanical thermometer.Units with temperatures more than 52 degrees Celsius (125 degrees Fahrenheit) and 54 degrees Celsius (130 degrees Fahrenheit) accounted for 88.3 percent and 73.3 percent, respectively.We discovered temperatures that were potentially hazardous at all heater settings.
The majority of parents with children less than 6 years of age (51 percent) were not aware of the dangers of HTW to their children until they were informed.We came to the conclusion that children who lived on our military base were at significant risk for serious accidental HTW burns, which we documented.Furthermore, the qualitative settings that are now in use are not accurate indications of safe temperatures.As a result, we propose that health-care practitioners educate parents about the hazards of high-temperature water (HTW) burns to children and that maximum HTW temperatures be set at the 49 degrees Celsius (120 degrees Fahrenheit) advised by the American Academy of Pediatrics.
