  3. A cup and a culinary thermometer will be required in order to correctly determine the temperature of the hot water heater.
  4. If you haven’t used your water heater in at least one hour, turn on the faucet that is nearest to it.
  5. 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

  1. Water heaters are pre-programmed to operate at temperatures about 140 degrees Fahrenheit, which is recommended by OSHA.
  2. 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.
  3. 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.
  4. Recommendation from me Personally, I feel that the temperature of a water heater should be set around 130 degrees in practically all circumstances.
  5. However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.

How To Turn Up Your Water Heater

  1. If you are dissatisfied with the suggested temperature of your hot water heater, you may alter the settings to receive extra hot water.
  2. Although electric water heaters may require a screwdriver and potentially a tiny wrench or socket, most hot water heater settings are straightforward to modify.
  3. 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

  1. 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.
  2. Because of the length of the pipe and the small bore size, it will take longer for the hot water to reach the opening.
  3. Additionally, pipes that run beneath or outside the residence may be exposed to freezing or freezing temperatures in the winter and summer.
  4. 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.
  5. 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 Hot Water Be at the Tap?

  1. So, before we go into the nitty-gritty of the maximum settings, let’s address the question ″what is the optimal temperature for residential hot water?″ You’ll know exactly what temperature you should be aiming for when you’re in the shower.
  2. It’s crucial to consider two things when determining the appropriate temperature: how hot water can be before scorching you and how cold water can be before bacteria starts to thrive.
  3. Let’s take these variables one by one.

Water Temperatures vs. Bacteria

  1. As the temperature of the water rises, bacteria have a lesser chance of surviving.
  2. The amount of bacteria present in the water will be influenced by the temperature of the water in question.
  3. At temperatures more than 158 degrees Fahrenheit, all bacteria will die almost rapidly, if not immediately.
  4. At somewhat lower temperatures of 140 degrees Fahrenheit, bacteria will die within 2 minutes, with around 90% of them dying within 2 minutes.
  5. Bacteria can survive and multiply at temperatures ranging from 118 to 122 degrees Fahrenheit from there.

Finally, bacteria can survive at temperatures ranging from 90 to 108 degrees Fahrenheit, providing the ideal setting for survival.Knowing these temperature ranges can assist you in determining whether or not germs will be able to survive in your hot water.

Water Temperatures vs. Scalding

  1. While it is necessary to heat water in order to kill germs, it is equally crucial not to overheat the water.
  2. Hot water burns might result if you don’t take precautions.
  3. According on how long you are exposed to the water, the temperature of the water will cause burns on your skin.
  4. Burns will result with prolonged exposure to temperatures above 120 degrees Fahrenheit for more than 5 minutes.
  5. Temperatures of 130 degrees Fahrenheit produce burns in 30 seconds or less if not treated immediately.

When the temperature is 140 degrees Fahrenheit, you can be burnt in around 5 seconds.Burns occur in around 1.5 seconds at temperatures of 150 degrees Fahrenheit.It is critical to keep the temperature of the hot water below a certain threshold in order to avoid burns.

What Is the Maximum Temperature for a Hot Water Heater

  1. In order to avoid burns and to keep bacteria at away, you must know how hot the water must be before using it.
  2. What is the hottest temperature that your water heater can be adjusted to, on the other hand?
  3. The most common belief is that the highest temperature for a hot water heater is 120 degrees Fahrenheit.
  4. This manner, you may safely avoid burns while also reducing the spread of microorganisms in the water supply.

Keep Your Water Heater Temperature Range at the Right Settings

  1. As a result, you now understand what the optimal water heater temperature range is.
  2. Typically, a thermometer or a gauge mounted on the side of the machinery may be used to easily determine the proper hot water temperature for a certain application.
  3. By following the recommendations in this guide, you will be able to ensure that your hot water is at the appropriate temperature.
  4. You will be able to take a safe and enjoyable shower without causing any damage to yourself or your property in this manner.
  5. Please contact the professionals at All A’s Plumbing and Heating if you require assistance with your hot water heater.

What Temperature Should a Hot Water Heater Be Set at?

  1. What temperature should a hot water heater be set at?
  2. Do you have the same question as many other people?
  3. Setting the water heater to the proper temperature is critical for providing not just more pleasurable showers, but also longer showers.
  4. It also protects individuals from contracting infections.
  5. 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?

  1. There are two schools of thinking that can throw light on the topic of what temperature should be set for a water heater.
  2. 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.
  3. 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.
  4. According to the Mayo Clinic, Legionella bacteria may be found in both water and soil as non-infectious agents that do not cause disease.
  5. 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

  1. In accordance with the American Burn Association, children under the age of 16 account for 26 percent of all admissions to burn treatment facilities.
  2. 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.
  3. Young children also lack the ability to perform self-rescue maneuvers.
  4. Because of pre-existing medical issues, slower response time, and decreased mobility, the elderly are particularly vulnerable to hot water-related burn injuries.
  5. 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

  1. We require a properly functional immune system in order to defend ourselves against infections.
  2. Whenever an organism infiltrates our body, the immune system mobilizes an army of defense cells to combat the invasion.
  3. Because immune-compromised individuals no longer have a powerful defense army in their bodies, they are more susceptible to infection than the general population.
  4. Increased water temperatures may be required to destroy germs in those who have lowered immune system capabilities.
  5. 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

  1. 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.
  2. 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).
  3. 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.
  4. Naturally, if money is not an issue, you may always raise the temperature to 140 degrees Fahrenheit on a regular basis.
  5. 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.

What Temperature Should I Set My Water Heater At?

11th of March, 2020 Get in Touch With Us

Setting the Ideal Hot Water Heater Temperature

  1. Are you tired of burning your hands every time you turn on the hot water in the shower?
  2. What if you’re having trouble getting a comfortable water temperature, no matter how high you turn the faucet up?
  3. 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.
  4. 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.
  5. 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

  1. You can find out what temperature water should be at by visiting the Environmental Protection Agency.
  2. The optimum temperature is 120 degrees Fahrenheit.
  3. 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.
  4. This temperature, on the other hand, is not ideal for everyone.
  5. 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

  1. Do you have any at-risk individuals residing in your home?
  2. Those who are particularly sensitive to high temperatures may suffer serious consequences if they are exposed to overly hot water.
  3. 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.
  4. Temperature reduction is more safer for your infant and far more cost-effective in terms of energy use.
  5. 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 is the best temperature for your water heater?

Burn patients in hospitals around the province blame scorching tap water for their injuries, with 59 percent blaming it on the water. Therefore, the authorities considered whether or not the rule should be changed. After much deliberation, they concluded that the recommended temperature of 60 °C was required in order to avoid further problems.

The dangers of insufficiently hot water

  1. A kind of pneumonia caused by bacteria found in home water heaters causes about 100 hospitalizations in Quebec each year.
  2. The disease is caused by bacteria found in domestic water heaters.
  3. In this unusual type of pneumonia, known as Legionnaires’ disease, a bacteria known as Legionella is responsible for the infection.
  4. Children, the elderly, and people with a weakened immune system are the most vulnerable to the disease.
  5. It has the ability to target the immune system through the respiratory tract, which is particularly dangerous while individuals are in the shower.

Legionella, like many other forms of bacteria, thrives in stagnant water at temperatures below 50 degrees Celsius.Maintaining the temperature of the water in your tank at 60 degrees Celsius helps to avoid the growth of bacteria that cause Legionnaires’ disease.It is for this reason that it is so critical to adhere to the temperature guideline.Water heater draining every year was thought to be beneficial for preventing the accumulation of germs and deposits for a long time, but today the technique is considered useless.As a matter of fact, some plumbers and manufacturers will inform you that emptying your device can shorten its useful life.

The solution? Install a temperature regulator.

  1. It is advisable to install a temperature-controlling device in order to limit the danger of burns caused by scorching tap water in the home.
  2. A thermostatic mixing valve, which is attached to the water heater output, allows you to maintain a consistent water temperature, such as 49 degrees Celsius.
  3. When the required temperature is reached, it automatically mixes hot and cold water to achieve it.
  4. With the gadget, you can limit the danger of scorching on any type of unit.
  5. It costs roughly $150 and is universally compatible.

Thermostatic mixing valves are fitted on faucet or shower outlets in the kitchen and bathroom to control the temperature of the water.They range in price from $10 to $50 and must be put on each light fixture.

Tips for your home

  • If you do not have access to a temperature-regulating equipment, you should exercise extra caution to avoid scorching and bacteria development by following these guidelines: Never leave a youngster unattended in the bath
  • If you are giving your child a bath, always check the water temperature first.
  • Educate your children on the importance of turning on the cold-water faucet first and turning off the hot-water faucet first.
  • Drinking hot water straight from the faucet is not recommended. Warm up cold water in a kettle or on the fire instead
  • Never adjust the temperature on the thermostat
  • instead, set it at a comfortable level.
  • Make sure you don’t turn off the water heater fuse before leaving your house for a short period of time. The temperature of the tank water must be kept at the specified level at all times.

Setting your water heater’s temperature for best results

  1. 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.
  2. In addition to higher power expenses, a malfunctioning water heater might result in water that is either scorching hot or ice cold.
  3. 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.
  4. 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.
  5. 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.

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.
  1. But what about the expenses of energy?
  2. We get what you’re saying!
  3. Water heaters account for around 14-18 percent of the total energy consumed by a residence on a typical day.
  4. Furthermore, it may be tempting to lower the temperature in order to save money.
  5. 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!

Adjusting Your Water Heater Settings: How To Maximize Efficiency

  1. Not many people are aware that selecting the proper water heater settings may result in substantial savings.
  2. Indeed, while the majority of people don’t give their hot water heater settings a second thought, they are actually highly critical in many situations.
  3. Not only will it save you money, but it will also make your showering experience more pleasant as a result of it.
  4. Here is a breakdown of the procedures.

Default Hot Water Heater Settings Can Vary

  1. Water heaters in Phoenix are frequently shipped with preset temperature settings that are as high as 140 degrees Fahrenheit or more.
  2. That is far greater than the majority of individuals require, although manufacturers do so for a variety of reasons.
  3. For starters, germs cannot thrive in water that hot, according to the Department of Energy.
  4. Increased gas or electric water heater settings can be beneficial for people who have weakened immune systems or respiratory illnesses.
  5. In addition to impressing consumers who have presumably recently replaced their tank since the previous one had ceased performing correctly, high temperatures can also be beneficial.

Once this psychological trick wears off (and assuming you don’t have a sickness that makes you particularly susceptible to bacteria), you’ll likely receive far more joy from saving money on your water bill, which we’ll teach you how to achieve in the next section.

How Much Are Your Gas and Electric Hot Water Heater Temperature Settings Costing You?

  1. As a general rule, every 20 degrees you reduce the temperature of your gas or electric water heater, you may expect to save as much as ten percent on your utility bill.
  2. That’s not too shabby after all!
  3. In reality, it adds up over time, and you can almost certainly come up with a number of better uses for the money you save.
  4. ″But hold on a minute,″ you may be thinking.
  5. ″I really enjoy taking hot baths!″ However, you almost probably do not take showers above 140 degrees Fahrenheit, which can cause scorching because of the high temperature.

It’s conceivable that you won’t even notice a difference.No matter what happens, raising the temperature is a simple process.It has also been known to cause aged hot water heaters to stop functioning.

How To Adjust Your Gas and Electric Hot Water Heater Temperature Settings

Now that you understand why you should reduce the temperature of your water heater, let’s have a look at how to go about doing so effectively.

Step One: Get An Accurate Temperature Reading

  1. It’s likely that the thermostat dial linked to your water heater tank is not functioning properly.
  2. As a result, you should really use a thermometer to monitor the temperature of the water flowing out of your faucet.
  3. The Department of Energy suggests that you measure the amount of water that is flowing out of the faucet that is the furthest away from your water heating system.
  4. Make a note of the settings after you’ve found them.

Step Two: Figure Out Where to Make the Adjustment

There are several distinct types of water heaters, and we’ll go through each of them separately.

Electric Water Heater Settings

In the case of an electric water heater, you must modify the hot water settings at the top and bottom of the unit. Both controls, which are often concealed behind a panel and consist of knobs that you crank to establish the appropriate electric water heater thermostat settings, are typically located on the same side of the panel.

Gas Water Heater Settings

Newer gas water heaters are equipped with temperature controls that are similar to those described above in the section on electric water heaters. Most gas heaters, especially older models, feature a temperature knob near the base that may be easily adjusted to the appropriate temperature.

Tankless Water Heater Settings

  1. Finally, tankless water heaters are available.
  2. This is likely the simplest modification to make because most thermostats include an LED screen that allows you to directly control the thermostat’s temperature.
  3. In addition to being convenient, these systems frequently allow you to modify the tankless water heater settings more accurately than you could with traditional dial-based adjustment methods.

Step Three: Make The Adjustments

  1. If you have an electric unit, make sure to turn off the electricity to it before modifying the hot water heater settings at the top and bottom, as we previously discussed in detail.
  2. This may be accomplished simply turning off the necessary settings on your circuit breaker panel.
  3. Doing so is also recommended in the case of a gas water heater that consumes some power (as some newer units do).
  4. But hold on a minute!
  5. What temperature should you choose as a starting point?

The Department of Energy suggests that you set your heater to 120 degrees Fahrenheit for the best performance.That should be sufficient heat for the majority of applications in your house.Some water heater temperature controls now include buttons that read ″A-B-C″ instead of numbers, which makes them easier to use.Generally speaking, A denotes 120 degrees, B denotes 130 degrees, and C denotes 140 degrees, respectively.To double-check these settings, consult the owner’s handbook for your water heater.

Step Four: Tweak the Settings as Necessary

After you’ve made the necessary adjustments to your gas or electric water heater thermostat settings, you may discover that you need to make a few more adjustments to get the best setting. You’re trying to strike the perfect balance between comfort and cost-effectiveness. If that’s more than 120 degrees Fahrenheit for you, there’s nothing wrong with that. Make the necessary adjustments!

Frequently Asked Questions

Is 150 Too Hot For A Water Heater?

It is nearly guaranteed that a temperature setting of 150 degrees will be too hot for your water heater. The likelihood of experiencing scalding is quite high at that temperature. You should be concerned about your youngsters, who may experiment with the temperature settings on the faucets while completely unconscious of the risk and end up scorching themselves.

What Is The Maximum Temperature For A Water Heater?

The highest temperature setting for the majority of water heaters is 150 degrees Fahrenheit.

Is 140 Too Hot For A Water Heater?

  1. Yes, temperatures above 140 degrees Fahrenheit are uncomfortable for the majority of people.
  2. The only exception would be persons who require an additional layer of protection against germs, which cannot thrive in water at that temperature.
  3. However, because such a state does not protect you from scorching, you will almost certainly need to install an equipment at the showerhead that cools the water before it is discharged from the showerhead.

Why Is My Water So Hot?

If you haven’t changed the settings on your hot water heater in a long time, they are most likely still set to the factory default of 140 degrees. The latter is especially true if your hot water heater was only recently installed; the old one was almost certainly altered at some time over the years, whereas the new one is set to the manufacturer’s recommended settings.

How Hot Should a Water Heater Be?

  1. The optimum temperature setting for a water heater is an issue that is frequently disputed in the industry.
  2. 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.
  3. 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.
  4. 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.
  5. 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

  1. The majority of people are unaware of how hazardous hot water may be.
  2. 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.
  3. 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.
  4. Despite the warnings, homeowners frequently turn up the temperature of their water heater to unsafe levels.
  5. 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.Providing plumbing services in the Lakewood Ranch, FL area, Custom Air Inc.is now available to install anti-scald devices in your shower or tub, tempering valves at your hot water outlet, replace your hot water tank, or install tankless hot water systems.

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)
<160°F 1 second
<149°F 2 seconds 0.5 seconds
<140°F 5 seconds 1 second
135°F 10 seconds 4 seconds
133°F 16 seconds
<130°F 35 seconds 10 seconds
127°F 1 minute
125°F 2 minutes
124°F 3 minutes
120°F 10 minutes

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
  • and
  • 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.

Why Your Hot Water Doesn’t Last Long Enough

  • Have you ever gotten into a hot shower only to have it turn icy cold seconds later? The worst part is that it happens every day, whether it’s the alarm in the morning or the bedtime routine at night. Here are a few tips and suggestions from Warner Service Inc. in order to keep the hot water flowing for longer: Increase the temperature setting on the hot water heater. One of the most straightforward methods to extend the duration of a hot shower is to use less hot water while the water is still at a high temperature. To accomplish this, raise the temperature setting on the thermostat that is linked to the hot water heater tank, as shown below. (This is not the thermostat mounted on the wall.)
  • Shower with a low-flow showerhead. If you haven’t changed your shower head yet, consider switching to a low-flow one. The apertures in these plumbing equipment are smaller, allowing the water to exit more quickly. This naturally pressurizes the water and drives it out at a slower rate than would otherwise be the case.
  • Keep an eye out for alternate sources of hot water in your home. The shower isn’t the only spot in your house where you’ll find hot water. Even if the dishwasher and washing machine are not in use at the same time, they have an impact on the amount of hot water available. Washing the dishes after a hot shower and doing laundry with cold water are good ideas. Insulate the domestic pipes as well. In order to enhance the insulation of home hot water pipes, a plumbing specialist should be called in. Hot water leaves the heating tank and travels through pipes to the shower, washing machine, and dishwasher, among other places to use. The water can quickly lose its heat while traveling through pipe to reach faucets or shower heads if the piping is not properly insulated. Inspect the heating components. The hot water heater might be the source of the plumbing issue with the hot water, if that is the case. Water will not be heated to the temperature specified on the tank’s thermostat if the heating element is not operating properly. The heating element’s size varies based on the type of energy source it employs (gas, solar, or electric). Elements may be simply updated and frequently enhance the overall operation of the hot water system.
  • Perform regular maintenance on the hot water tank
  • A badly maintained hot water tank is one of the most common plumbing problems associated with a hot water system. Sediment and rust accumulate in the tank’s inside. This has the effect of lowering the water quality and slowing the effects of the heating element. These plumbing issues may be resolved with a simple draining and cleaning procedure. A plumbing specialist can execute this job in a short amount of time.
  • The hot water tank should be replaced or supplemented. If your hot water system isn’t operating properly, you should consider upgrading the complete system. Even though many hot water systems only have a single heater tank, it is feasible to install a second tank in order to boost performance. Additionally, modern heater tanks are a better alternative for older homes that require renovations. Consider installing a tankless water heater. The water heater is responsible for providing your home with a plumbing system that provides hot water for all of your needs. Tankless water heaters are more energy efficient and help you save money on your utility costs.

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.
