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?

Check the temperature setting on the water heater (if one is available) or take a temperature reading from the faucet to determine what it is currently. After turning on the hot water faucet, allow it to run for a few minutes before getting the temperature reading.

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!

How hot should I set the water heater?

When it comes to your water heater, the temperature should be set so that it is just hot enough to meet your requirements.
But many homeowners are unaware of the normal settings and thus set their water heater’s temperature too high.
Household tasks, and notably showers and baths, may be completed at 120 degrees Fahrenheit with little problem.
If the temperature of your water reaches 125 degrees Fahrenheit, you will be scalded if you do not take action within two minutes.
Never raise the temperature of your home above that unless you have a specific need to do so, such as sanitizing dining utensils.

Also, always inform family members or other individuals who live with you that you have increased the temperature of the water by using the thermostat to adjust it.If they don’t, they risk being scalded in the shower.The only time you will actually require hot water that is higher than 120 degrees is when you are doing the dishes.It is not even necessary for the water to be really hot.Hot water at a temperature of 130 degrees Fahrenheit will destroy bacteria that can aid in the transmission of germs.However, this type of temperature for hot water is typically used in the dishwasher to clean the dishes.

While it is possible to physically wash dishes at this water temperature, you should do so at your own discretion and risk.
This is due to the fact that this type of hot water may really scald the human skin.
It’s not necessary to raise the temperature of the water in your house to the point where it may scald someone, in this case anyhow.
Just keep in mind that any water temperature greater than 120 degrees might be harmful to someone.

As a result, you should always check your water thermostat and inform anybody who lives in your home that you have it set to a higher temperature.Aside from that, reducing the temperature might have negative consequences.If you have more than one person living in your house, it is possible that they will come out of the shower cold.

In practice, if you want to save money while still being able to manage the temperature of your water heater, this is a terrific option for energy efficiency.However, just like with any other home improvement project, you must keep an eye on it to ensure that everyone is safe.RELATIONSHIPS BETWEEN TIME AND TEMPERATURE IN SCALDS 125 degrees Fahrenheit 1 and a half to two minutes 130 degrees Fahrenheit Approximately 30 seconds at 135° F Approximately 10 seconds at 140° F 145 degrees Fahrenheit in less than 5 seconds It takes less than 3 seconds.150 degrees Fahrenheit Approximately 1 1/2 seconds at 155° F Approximately one second The table is provided courtesy of the Shriners Burn Institute.

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.

Age

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.

Energy Consumption

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.

Conclusion

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.

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 cases, the following is what each label means: Low (or Warm) = 80-90°
High (or Cool) = 100-110°
Low (or Cool) = 110-120°
High (or Cool) = 120-140°
Low (or Warm) = 120-140°
High (or Cool) = 120-140°
High (or Cool) = 120-140°
High (or Cool) = 120-140°
High (or Cool) = 120-140°
120 degrees is represented by the hot (or triangle symbol).
A = 130 degrees
B is equal to 140°.
C is equal to 150°.
Very Hot = 160 degrees Fahrenheit

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.

What temperature should the water be coming out of the kitchen faucet at the sink when it is 25-to-30 feet away from the hot water heater?
A- Depending on the local code, but often a minimum temperature of 100°F (38°C).
105 degrees Fahrenheit (40.5 degrees Celsius) maximum is desired in nursing homes and other places where children are present.

What temperature should the water be flowing out of the faucet in laboratory 2′ from the hot water heater be?Installation of a pressure balance/temperature faucet should be done when in doubt to avoid accidental burns.Several installations, for example, send the same temperature to the dishwasher and washing machines as they do to the rest of the house.For optimal cleaning, a household dishwasher requires temperatures between 140 and 160 degrees Fahrenheit (60 and 70 degrees Celsius).Germs thrive at temperatures less than 140°F (60°C).When working on a combination occupancy, such as a business establishment with residential units that share the same domestic H/W supply, I utilize a commercial heater that produces 180°F (82°C) water as a result of the combination occupancy.

As most qualified plumbers are aware, water at 160°F (70°C) for cleaning and 180°F (100°C) for sterilization should be used instead of chemicals.
In the hot water tank, water temperatures below 125°F (52°C) encourage the growth of all forms of bacteria (called incubators).
As a result, they sued everyone until the manufacturers reduced the safety of home water heaters to an extremely dangerous level.
Use of high-quality mixing valves to deliver extremely hot water to the dish washer and laundry machines, which will kill germs, and high-quality tempering valves to regulate the temperature of the water after it has passed through these devices and is circulated throughout the system are the solutions to the temperature dilemma.

When the hot water does reach a showerhead or faucet, you may install the following safety measures, which have been proven to work quite well in the past and are known as pressure/temperature regulating/valves or balancing valves, among other names.A pressure drop is created when someone else flushes the toilet, and the user is protected from being burnt because the pressure decrease is not caused by the user being burned.When hot water is used in a dish washer, for example, this quick change in temperature or pressure will not scare someone who is taking a bath.

Children and adults can be severely burnt in as little as two seconds or less in water that is 149°F…

Is 120 degree water hot?

One temperature was designated as the ″use temperature,″ while the other was designated as the ″maximum temperature″ to prevent scorching. It is widely acknowledged that the maximum safe hot water temperature that should be given from a fixture is 120 degrees Fahrenheit. The use of hot water exceeding 120 degrees Fahrenheit might thus be deemed potentially dangerous.

Will 117 degree water burn you?

Scalding is induced by the use of extremely hot water and can result in burns. Most residential water heating systems in the United States, on the other hand, will keep their water at a temperature between 120 and 160 degrees. When the water is between 110 and 112 degrees, it will take at least twenty-five minutes before it may cause any skin irritation.

Will 122 degree water burn you?

The severity of tap water scalds is determined by the temperature of the water as well as the length of time the skin is exposed to the hot water. Human exposure to hot water at 140°F may cause a major burn in 3 seconds, whereas exposure to hot water at 120°F can cause a serious burn in around 10 minutes.

Is 115 too low for water heater?

Going too low increases the chance of germs developing in your pipes or water heater, whilst going too high increases the risk of burning your pipes or water heater. You’ll want to find a happy medium between the two extremes if you want to avoid either one. We recommend that you maintain the heater set between 110 and 120 degrees all of the time.

What is the maximum temperature that the water heater should be set at so as not to scald?

Remember, the Consumer Product Safety Commission advised in 1988 that water heater manufacturers limit the maximum temperature to 120 degrees Fahrenheit in order to prevent burns.

Can water be heated above 100 degrees?

Liquid water may be hotter than 100 degrees Celsius (212 degrees Fahrenheit) and colder than 0 degrees Celsius (32 degrees Fahrenheit). Superheating is the process of heating water over its boiling point without causing it to boil. … When water that is extremely clean, free of air bubbles, and contained in a smooth container is disturbed, it may superheat and then explode violently boil.

Is 50 degrees hot enough for hot water?

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.

What temperature of water is painful?

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.

There’s No Perfect Temperature For Your Water Heater

When it comes to your water heater, what is the ideal temperature setting? There isn’t a single perfect solution. Scald Awareness Task Group of the American Society of Sanitary Engineering has published a white paper on the subject, which essentially states that there is no ideal temperature to set your water heater to.

What’s a safe temperature for water?

Most water heaters have a warning label on the side that states that water temperatures beyond 125 degrees Fahrenheit can cause burns or death.
The water that comes out of a home’s plumbing fittings should not be any hotter than 120 degrees Fahrenheit in order to be safe.
The helpful illustration below (courtesy of Charles Buell) illustrates how quickly second- and third-degree burns can occur at temperatures that are within the range of any modern water heater’s capability.
Simply lowering the temperature of your water heater until it reaches a safe 120 degrees will not be sufficient to eliminate potential scald hazards.
This is because the thermostat on a water heater is not designed to maintain a constant temperature; rather, it is designed to maintain a temperature within a specific range of temperatures.

Several blogs have been written by Seattle home inspector Charles Buell explaining how this works.One blog describes how water heaters can run out of hot water more quickly than is necessary.Another blog discusses how a water heater produces different temperatures at different stages of its heating cycle.The temperatures in a big home that was heated by two high-efficiency water heaters varied widely, as I discovered recently during a routine check of the property.After turning on the hot water at a fixture for the first time, the water temperature was chilly at initially; this was due to condensation forming in the hot water pipe, which had cooled the water down to room temperature.As soon as the hot water from the tank’s top reached the plumbing fittings, the temperature of the water swiftly increased to approximately 154 degrees — hot enough to produce first-degree burns in an instant and second-degree burns in less than one second.

The water only remained at this temperature for a few seconds before rapidly cooling back down to around 135 degrees.
However, even though a tempering valve had been built to mix cold and hot water immediately at the water heater output, it was not adequate to properly regulate how hot or cold the water was when it reached the fixtures.
Minnesota does not have any restrictions for the temperature of household water.
All new or refurbished showers or shower-bath combinations in Minnesota are required to include anti-scald mechanisms, although this does nothing to address the final temperature of the water flowing out of a fixture (4715.1380 Subp.

5).Anti-scald devices are only effective in preventing people from being scalded by a rapid change in temperature when having a bath or shower.The pressure in the cold water line would decrease rapidly if a toilet flushed while someone was having a shower with an outdated shower valve that did not have an anti-scald mechanism.

As a result, the water temperature in the shower would swiftly rise.

Lower Temperatures Allow Bacteria Growth

It appears as though turning down the temperature of the water heater to, say, 115 degrees would be the best approach to help prevent unintentional scorching, but lower temperatures really cause additional problems.
Legionellae bacteria, which is responsible for Legionnaires’ Disease, may live and even proliferate in the water heater tank when the temperature is between 135 and 140 degrees Fahrenheit.
It is estimated that up to 600,000 cases of Legionnaires’ Disease are misdiagnosed as pneumonia each year, according to LegionellaPrevention.org, due to the fact that Legionella is not routinely checked in medical settings.
The time it takes for Legionellae Bacteria to be killed at various temperatures is depicted in the graphic below.
The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASSE) suggests that you keep the water in your water heater tank between 135 and 140 degrees Fahrenheit to help avoid bacteria development.

It goes without saying that this presents a scorching hazard.

So What’s the Answer?

To help minimize bacteria development and reduce the danger of scalding, have a plumber install a tempering valve and raise the temperature of your water heater to roughly 135 – 140 degrees Fahrenheit, as recommended by the American Society of Heating, Refrigeration, and Air Conditioning.
The installation of a tempering valve on the hot water outlet at my home last year, which allowed me to get more water out of my water heater, was the subject of a previous blog post.
The installation of these valves in every home would be a wise decision.
It is possible to maintain a dangerously high, Legionellae-killing temperature within the water heater tank while also mixing in cold water exactly at the outlet, ensuring that you do not get this dangerously high, Legionellae-killing temperature in any other fixtures in your home.
Although a tempering valve will not ensure safe water temps, as I noted in my tale about the recent inspection with dangerously hot water, using one will bring you a lot closer to that goal.

How Hot Should a Water Heater Be?

The optimum temperature setting for a water heater is an issue that is frequently disputed in the industry.
Homeowners who are well-informed understand that heating water – and keeping it at a high temperature – accounts for a significant portion of their household’s energy budget.
Some individuals lower the temperature because they are under the clear notion that heating water to lower degrees consumes less energy and, as a consequence, resulting in significant energy savings.
Another school of thought holds that hotter water may be combined with bigger quantities of cold water to achieve the appropriate temperature, and that doing so actually saves money because it results in less utilization.
Both of these responses are right in their own way, but they are also erroneous in another manner.

The reason behind this is as follows.

Hot Water is Dangerous

The majority of people are unaware of how hazardous hot water may be.
Any contemporary water heater is capable of producing water that is hot enough to induce first degree burns in less than a second and second degree burns in less than a second.
Hot water tanks are even equipped with warning placards that warn that temperatures of 125 degrees Fahrenheit or more can result in burns or death.
Despite the warnings, homeowners frequently turn up the temperature of their water heater to unsafe levels.
Higher temperatures are OK if the correct safety mechanisms are in place, but most homeowners do so for the wrong reasons and fail to install the essential safety equipment in the process.

This white paper was issued in March 2012 by the American Society of Sanitary Engineering’s Scald Awareness Task Group, which is entitled ″Understanding Potential Water Heater Scald Hazards.″ That article was mostly concerned with water heater settings and the common misunderstandings that homeowners have about how to utilize their water heaters.For example, most people believe that setting the water heater thermostat to 120 degrees will result in a continual stream of 120-degree water pouring out of the faucet.This is incorrect.Realistically speaking, such temperature has a significant operational margin.It may be heated to temperatures as high as 145 degrees Fahrenheit at first, and then let to cool in the tank over time.Splashing is a significant issue when water heaters are purposefully set at a high temperature to allow for bigger quantities of cold water to mix at the point of usage, which rises considerably when this occurs.

While showering, turning on a cold water faucet in the kitchen or flushing the toilet in a second bathroom might lower the amount of cold water flowing through the shower and cause major burns.
The use of anti-scald devices is intended to prevent this from occurring, although many homes do not have these devices installed.
Tempering valves put at the hot water exit can allow water tanks to run at greater temperatures in a safe manner, although they are not necessary in the majority of communities.

Warm Water is Dangerous

It is possible to be at risk in a different way by keeping water temperatures at 120 degrees or below.
Legionella pneumophila, the bacterium that causes Legionnaires disease, is most commonly found in the air conditioning systems of hospitals, office buildings, and cruise ships, among other places.
Recently published research, however, have revealed that household hot water systems may be responsible for as much as 20 percent of the cases detected each year.

The ASSE Recommendation

To avoid Legionella bacteria development, the American Society of Sanitary Engineering recommends that hot water tanks be maintained at a temperature between 135 and 140 degrees Fahrenheit, with the installation of anti-scald devices and tempering valves to prevent hot water injuries.
When it comes to making adjustments to your water system, only licensed plumbers should be engaged.
