What Temperature Should I Set My Water Heater At?
Power should be turned off at the water heater and the circuit breaker. Make your repairs and then re-connect the water supply.
Setting the Ideal Hot Water Heater Temperature
Are you tired of burning your hands every time you turn on the hot water in the shower? What if you’re having trouble getting a comfortable water temperature, no matter how high you turn the faucet up? These are not always indications that your water heater is malfunctioning, but rather that the temperature setting you have chosen is not optimal for your purposes. A water heater that has been installed incorrectly can have a significant influence on your life, even in areas that are not directly linked to your plumbing or heating system.
It can also have a negative influence on your health or the health of people who share your home with you.
A definitive or simple response cannot be given; rather, part of it is a matter of personal choice.
General Recommended Water Heater Temperature
You can find out what temperature water should be at by visiting the Environmental Protection Agency. The optimum water temperature is 120 degrees Fahrenheit. You will really save money because your water will not be hot enough to cause scalding, most small households will have adequate hot water for their needs, and reheating will not need an excessive amount of energy consumption, allowing you to save money on your utility bills. This temperature, on the other hand, is not ideal for everyone.
Considerations When Choosing a Water Heater Temperature Setting
You may find out what temperature water should be at by visiting the Environmental Protection Agency. The optimum temperature for water is 120 degrees Fahrenheit. You will really save money since your water will not be hot enough to cause scalding, most small families will have adequate hot water for their needs, and reheating will not need an excessive amount of energy use, allowing you to save money on your energy bills. This temperature, on the other hand, is not ideal for all people. It will be necessary to raise the temperature in certain homes far higher than this standard for a variety of reasons, which we shall address shortly.

What Temperature Should a Hot Water Heater Be Set At?
Previous PostNext PostYour water heater accounts for around 18 percent of the energy consumed by your house. 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.
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. BabyCenter.com states that “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 frequently leave the manufacturer.” 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. The temperature of the water tank is often set higher in big households, in order to support the increased demand for hot water
- Nevertheless, if you want to save money, every 10 degrees you lower the temperature of the water tank thermometer, you save 3 to 5 percent on 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.

Risks Of Too High Or Too Low Water Heater Temperature
You might be wondering what temperature to put your water heater to. When you purchase a water heater unit, the temperature is typically set by the manufacturer. However, this does not rule out the possibility of having some control over its temperature. The good news is that you may set the temperature to a level that is comfortable for you while yet ensuring the safety of your family. Previous to this, we wrote an article in which we spoke about how the heat in your shower might suddenly vary.
The temperature of the device is important since it can have an impact on how well it performs.
Top Risks of setting your unit temperature too high
An skilled plumber would advise against raising the temperature of your unit over the recommended level since it might endanger the safety of your children. It can also have an impact on your utility costs and the heater itself. In order to assist you, we have listed the following risks:
1. Scalding Accidents
Setting the temperature too high might result in scorching mishaps that result in burn injuries. According to the findings of a study on water heater temperature and attributes, many water heaters are frequently set at dangerously high temperatures. Several studies by the Centers for Disease Control and Prevention (CDC) have discovered that scald burns are the most common cause of injury in younger children. Every day, over 300 children between the ages of 0 and 19 are treated in emergency departments for burn-related injuries, with two of these children dying as a result of their injuries.
In order to avoid tap burns, experts strongly recommend that you have your water heater inspected. Accidents such as this may be prevented by allowing your water to flow for three minutes and then monitoring the temperature with a candy thermometer thereafter.
2. High electricity bill
Setting the temperature too high might result in scorching mishaps that result in burn injury. According to the findings of a study on the temperature and features of water heaters, many water heaters are frequently set at potentially hazardous temperatures. According to the Centers for Disease Control and Prevention (CDC), scald burns are the most common type of injury suffered by younger children. Burn-related injuries affect around 300 children between the ages of 0 and 19 every day, with two of these children dying as a result of their injuries.
Using a candy thermometer to monitor the temperature of your water after it has been running for three minutes will help you prevent these mishaps.
3. Lowers your unit’s service life
According to some sources, hot water can accelerate the accumulation of hard water mineral silt, particularly calcium carbonate, in the tank’s interior. It is possible that the buildup would cause corrosion in the water heater tank, which will result in a reduction in the estimated lifespan of the complete device. Leaks and polluted water might occur as a result of the rust accumulation in the storage tank. Another major reason for water heater failure is the deposit of rust on the interior of the heater.
We wrote an essay about why it’s important and how you can extend its lifespan.
Risk of setting your unit temperature too low
According to some sources, hot water can accelerate the accumulation of hard water mineral silt, particularly calcium carbonate, in the tank’s internal environment. It is possible that the buildup would cause corrosion in the water heater tank, which will result in the unit’s estimated lifespan being reduced. Leaks and polluted water might occur as a result of rust accumulation in the tank. Another major reason for water heater failure is the formation of rust inside the tank. We recommend that you do yearly water heater maintenance to extend the life of your water heater up to 12 years if possible.
Here’s where you can read more about it:
1. Legionnaires disease
Every year, around 100 people in the United States are sent to hospitals due to a form of bacterial illness that can be caused by water heaters. The infections connected with the bacterium were responsible for up to 12 percent of the country’s death rates. Specifically, the Legionella bacteria are responsible for this particular kind of atypical pneumonia. It is common to find this bacterium in water at low temperatures — often between 20 and 45 degrees Celsius. You can contract the disease if you inhale small water droplets in the air that contain germs that cause it.
Evidence indicates that the majority of the bacteria’s spread occurred through the provision of drinking water in private residences.
It has been shown that the danger of contamination is significantly reduced when water heaters are set at 60°C or 140°F.
Ideal Temperature For Your Water Heater
A form of bacterial illness that can be induced by water heaters causes over 100 hospitalizations in the United States every year. Illnesses caused by the bacterium were responsible for up to 12 percent of the country’s mortality rates. Specifically, the Legionella bacteria are responsible for this particular type of atypical pneumonia. Low temperatures – typically between 20 and 45 degrees Celsius – are conducive to the growth of this bacterium in water. Inhaling small water droplets in the air where the bacteria is present might cause you to get the sickness.
This bacterium was most likely spread through drinking water distribution in private residences, according to the evidence.
Researchers discovered that water heaters set at 60°C or 140°F have a significantly lower chance of contamination.
So, is it 120°F or 140°F?
We recommend keeping the temperature between 120 and 140 degrees Fahrenheit. However, you may regulate the temperature of your water heater between 130 and 140 degrees Fahrenheit, which is very useful for large water heaters used in hospitals and industrial settings. In case you have little children at home, set the temperature to 120°F, which is considered safe by the majority of the population.

- Water heater temperature: If your dishwasher does not have a booster heater, you may wish to keep your water heater temperature at 140 degrees to get the best cleaning possible. This function, on the other hand, may be found on the majority of current dishwashers. For further information, consult your owner’s handbook. Your physical and mental well-being: While the bacteria growth within a tank set at 120 degrees is acceptable for most people, if you have a compromised immune system, you should consider maintaining your tank at 140 degrees. The amount of persons that live in your residence is as follows: It is unlikely that you will run out of hot water if you maintain the tank at 120 degrees for an extended period of time if you live alone. If, on the other hand, six family members shower back-to-back each morning, the additional 20 degrees helps to guarantee that everyone has hot water. If you have children, you should consider the following: Scalding at the faucet is less likely to occur when your water heater is set to 120 degrees, which is especially significant if you have children or elderly family members living with you.
How to Adjust the Water Heater Temperature
Perhaps you want to raise the temperature of the water heater to assist your dishwasher in doing its work more effectively, or you want to lower the temperature to reduce scalding. In any case, the following actions should be followed to alter the water heater setting:
- Obtain an accurate reading of the present temperature by turning on hot water at a faucet that is the furthest away from the water heater, as shown in the diagram. Place a thermostat under flowing water to see whether or not an adjustment is required
- Locate the thermostat dial by turning it clockwise: Gas water heater tanks include dials towards the bottom of the tank that regulate the temperature of the water. Water heaters that run on electricity frequently have their thermostats tucked away beneath screw-on panels. If your electric water heater contains upper and lower heating components, there may be two dials on the control panel. Take the following measurements and make the necessary adjustments: Increase or decrease the temperature setting on the thermostat by a little amount from its beginning level. Then you’ll have to wait a few of hours. Measure the water temperature once more and make any additional modifications that are necessary. Whenever you’re through, make a note of the final temperature on the dial so that you may quickly adjust it in the future.

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.
- Setting the Water Heater to Its Optimal Performance Professionals recommend that you keep the temperature of your water heater between 130 and 140 degrees Fahrenheit at all times.
- While increasing the temperature over the suggested setting might result in burns, decreasing the temperature below the recommended level can also be hazardous.
- 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.
- Check the temperature of your water heater.
- 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.
- 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.
- The average lifespan of a hot water heater is predicted to be between 8 and 12 years.
- Water heaters require regular maintenance.
- 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 temperature is right for your water here?
When it comes to conserving energy at home, one of the first things that comes to mind is most likely changing the thermostat settings on your home heating system to the lowest possible level. Nevertheless, what about the temperature control device on your water heating system? The factory default setting on most water heaters supplied today is 140 degrees, and sometimes even higher – a temperature that is high enough to induce scorching but not high enough to meet the needs of most people (there are exceptions to this, however, as we will see).
However, the most compelling reason to lower your water temperature is to save electricity (and, consequently, money).
When you adjust your water heater’s thermostat to 120 degrees Fahrenheit rather than 140 degrees Fahrenheit, you’ll save around $50 per year in standing heat loss and more than $400 per year in fuel use.
A 140° setting is right in certain circumstances
However, while the majority of individuals can get by with a 120-degree setting, there are some situations in which a 140-degree setting is more appropriate. For example, if you have a member of your family who has a compromised immune system or chronic respiratory condition, a 140-degree setting is suggested to avoid Legionnaires’ disease and other water-borne illnesses. Additionally, if your dishwasher does not pre-heat the water, you may want to keep the temperature at a higher setting.

Should You Adjust Your Water Heater Temperature?
Most houses have a water heater, which is one of their largest energy consumers. If you’re searching for ways to reduce your energy consumption, this is a smart place to start. Prior to decreasing the temperature of your water heater’s thermostat by a few degrees, there are a few things you should consider. If you set the temperature too low, you run the risk of turning your water heater into a breeding ground for potentially harmful germs. If you set it too high, you run the risk of causing a scorching mishap to yourself or someone else.
- The quick answer is: 120 degrees Fahrenheit (degrees Celsius).
- At this temperature, dangerous microorganisms such as the kind that causes Legionnaires’ disease are stopped from proliferating and may even be eliminated entirely.
- As a result, other organizations such as the Occupational Safety and Health Administration (OSHA) suggest that the temperature of the water heater be maintained at 140 degrees Fahrenheit.
- Choosing a temperature closer to 140 degrees Fahrenheit is preferable, especially if anyone in the household has a weakened immune system.
- What Is the Deal with Scalding?
- You’ll never know when the scorching water will hit you since it takes several seconds for hot water to travel through your pipes and reach your faucet or showerhead.
- There is a remedy to the tug-of-war that exists between pathogenic safety and scalding safety: anti-scald valves are available.
- Installing an anti-scald valve may be a simple do-it-yourself operation for an experienced amateur plumber, but the difficulty of the task is determined by the configuration of the plumbing system.
- What, however, is the state of energy efficiency?
Saving energy and money is vital, but it isn’t nearly as important as protecting yourself and your family from potentially life-threatening diseases. Having said that, it is feasible to reduce expenses without relying on your water heater’s thermostat to do this:
- Reduce the amount of hot water you use. Shower for shorter periods of time and use the dishwasher instead of hand cleaning, which often consumes more water. Insulate your hot water heater as well as the lines that supply it. There are pre-cut pieces of insulation that are simple to install and can be completed in an afternoon, making this a do-it-yourself job for the weekend. It’s time to replace your water heater. It is estimated that the average water heater will survive 8 to 12 years if it is properly maintained. Water heaters that are outdated or in need of maintenance may be significantly less efficient than they were on the day they were installed. Choose a replacement that complies with the voluntary energy efficiency requirements set by theENERGY STARprogram while buying.

How to Adjust Your Water Heater’s Temperature
It has been shown that even ordinary tap water might be hazardous. Every year, a number of individuals (mainly youngsters) are sent to hospitals after suffering burns as a result of water heaters that have been set excessively high. But what exactly does “too high” imply, and how can people ensure that their water heaters are set at a temperature that will not cause them to be burned, is a mystery. The Environmental Protection Agency (EPA) recommends a hot temperature setting of 120 degrees Fahrenheit for both safety and energy savings reasons.
Use this procedure if the stickers on the water heater do not inform you how to set the temperature and you are unable to locate the owner’s handbook.
- Make sure to run hot water for at least three minutes from the faucet nearest to the water heater. Fill a glass with hot water and check the temperature
- If the water temperature is higher than 120 degrees, adjust the dial, wait approximately three hours, and then check again. Continue until the water reaches 120 degrees Fahrenheit.
The temperature of the water heater should be checked the next morning before anyone uses any hot water as a last check. Once you have found the perfect setting, make a note of it on the dial so that you do not have to go through the testing procedure again. Here are some more suggestions for extending the life of your water heater.
No one enjoys taking a cold shower. It’s much worse when you are scalded when the hot water is turned on. It is critical to correctly regulate the temperature on your water heater, not only for your health and safety, but also to save money on your power bill. Here’s how to regulate the temperature of your water heater to save money while also protecting your skin from sun damage.
The correct temperature range
It is recommended that your water heater be set within a specified temperature range for a variety of different reasons. A low temperature setting not only results in hot water that is merely lukewarm at best, but it can also promote bacterial development, which can lead to illnesses such as Legionnaires’ disease. This may be avoided by adjusting the temperature of the water heater to a level at which the bacteria Legionella cannot survive. A temperature of at least 140 degrees Fahrenheit (60 degrees Celsius) for water heaters is recommended by the Occupational Safety and Health Administration (OSHA) to prevent Legionella and other germs from growing in the water.
- The time it takes for third-degree burns to occur at 150 degrees Fahrenheit (66 degrees Celsius) is less than two seconds.
- Not to mention that a water heater that is set too hot might result in an excessively expensive power bill.
- The greater the distance between a faucet and the water heater, the greater the amount of heat that will be lost as the water flows, especially if the pipes are not insulated.
- When determining the appropriate temperature for your family and household, use your best judgment.
Make an adjustment, test it, and continue the process until you’ve found the ideal temperature setting for your house and water heater, which may take many attempts. Currently playing: Keep an eye out for this: Take a look inside the CNET Guide to Smart Living. 1:00
Adjusting water heater temperature
The interface used to control the temperature of a water heater will differ depending on the kind and model. Fortunately, the majority of water heater models can be modified in the same way. For example, most contemporary gas and electric water heaters are equipped with a thermostat concealed behind an insulated access panel. Electric water heaters are frequently equipped with two thermostats: one at the top of the tank and another at the bottom. Furthermore, most tankless water heaters include a display with a temperature reading as well as controls for altering the water heater’s temperature.
Turn on the water in the bathroom or kitchen sink and let it to run until the water is completely hot before using.
The process of adjusting a tankless water heater is quite similar to the process of adjusting your air conditioning thermostat. Adjust the temperature by using the digital control panel, which may be adjusted up or down as desired.
Gas or electric water heaters
Some gas water heaters include a dial towards the bottom of the device that may be adjusted simply by turning it – no tools are required for this operation. Nonetheless, most current tank water heaters (whether gas or electric) require a bit more effort, but the process is still straightforward and should only take a few minutes.
- Turning off the water heater’s electricity at the circuit breaker is the first step. To remove a thermostat(s), locate the access panel for the thermostat(s) and remove it using a screwdriver
- Remove the insulation by peeling it back. To adjust the thermostat, use a flathead screwdriver to turn it up or down.
- If your water heater has two thermostats, make sure they are both set to the same temperature. The temperature on the top thermostat should be a few degrees higher than on the bottom thermostat.
- Replace the insulation and re-install the access panel, if necessary. Reconnect the water heater’s power supply
- It is possible that you may need to relight the pilot light on a gas water heater.
Once you’ve made the necessary adjustments, you should wait at least three hours before checking the water temperature once more. It is possible that you may need to make more modifications in order to get the desired temperature. If you’ve increased the temperature and are still getting chilly showers, it’s possible that your hot water heater has to be serviced or completely replaced. Is the energy efficiency of your home high? Here are five different methods to find out. CNET’s Guide to Smart Livingis a one-stop shop for tips, techniques, and how-to guides that can help you live a more intelligent life.
What Is The Ideal Temperature For Water Heaters?
The water heater in your house is the second greatest energy consumer in your home, accounting for around 18 percent of your monthly energy cost. Making certain that your hot water heater is set to the appropriate temperature will not only help you save money on your monthly energy bills, but it will also help you extend the life of the unit as well. A simple test performed within your house will assist you in determining whether or not you should check the temperature of the unit. Turn on a faucet that only has hot water coming out of it.
- Is it too hot for you to wash your hands or take a bath?
- If the water never becomes warm, it is possible that the temperature is set too low.
- A surprising amount of people are unaware that lowering the temperature on their air conditioning unit too low can be just as harmful as setting it too high.
- A tank that is kept at a too-cold temperature can encourage the growth of germs.
- The amount of elements in your home will influence whether or not you should set your unit to a temperature greater than 120°.
The Influence of Water Heater Temperature Factors Check out the recommended 120-degree setting. Depending on whether or not the water heats up sufficiently, the following factors may influence how high you should set your gauge:
- Whether the device is fueled by electricity or gas
- The type of pipe material used in your residence (PEX, copper, or plastic)
- Whether the hot water unit is equipped with a typical tank or is tankless
If any of the following apply, putting the hot water heater between 120 and 140 degrees should be considered:
- Set your hot water heater between 120 and 140 degrees if you have any of the following circumstances:
Hot water heaters can help you save money on energy. It is estimated that simply lowering the temperature of your hot water heater by 10 degrees, you would save three to five percent on your monthly energy bills. If you have recently acquired a hot water heater or have recently moved into a new house, double-check the settings. A temperature of 140 degrees is usually chosen as the default by most manufacturers, which may be too hot for certain houses. You may ascertain the temperature of the water by taking a reading from the water coming from the faucet or by looking at the gauge on the device.
When you turn on the hot water valve, the booster mixes the hot water with the chilly water from the input valve to provide you with a pleasant water flow.
Large families might benefit considerably from the system, which circulates hot water throughout the plumbing system so that it does not have time to chill before reaching the faucets.
Try out several temperature settings to find the one that works best for your house.
What’s the Best Temperature for Your Water Heater?
You probably don’t give your water heater much thought till you’re in the middle of a shower and the hot water stops working. It might be much more dangerous if the water is overly hot and causes scorching. Although you have the ability to modify the temperature of your water heater, should you? Even while you would believe that water heaters have a standard suggested temperature, this is not the case. Some water heater manufacturers factory-set their water heaters at 120°F (49°C), while others factory-set their water heaters at a default temperature of 140°F (60°C).
The Occupational Safety and Health Administration (OSHA) advises that the temperature be maintained at or above 122 degrees to assist avoid the formation of potentially dangerous microorganisms in the workplace.
Should I Change the Water Heater Temperature?
For the purpose of determining the most appropriate water heater temperature for your house, there are various elements to take into consideration.
Hot Water Kills Harmful Pathogens
A health problem arises when Legionella, the bacterium that causes Legionnaires’ disease, develops in the water systems of residential properties. According to the Occupational Safety and Health Administration, water heaters that are kept below 140 degrees and that include scale and silt may promote Legionella growth.
Fortunately, the vast majority of healthy persons who are exposed to Legionella do not become ill. However, before you decide to turn up the temperature dial on your water heater, consider the following.
Hot Water Can Scald
The use of hot tap water is a leading cause of burn injuries and fatalities. Scald burns can be a serious threat in the house, especially if you have young children or elderly people living with you. Young children, because their skin is thinner, and the elderly, because their skin might be less sensitive to warmth and may be slower to respond to scalding water, are the two age categories that are most at risk for scalds. Adults may suffer third-degree burns if they are exposed to 150-degree water for even a brief period of time (as little as two seconds), according to the Consumer Product Safety Commission.
Though the temperature reaches 120 degrees, a five-minute exposure might result in third-degree burns even if the temperature is lower.
Minimize Risk with Anti-Scald Devices
The leading cause of burn injuries and deaths is hot tap water. It is extremely dangerous to have young children or elderly people in the house if you have a history of scald burns. Young children, because their skin is thinner, and the elderly, because their skin might be less sensitive to warmth and may be slower to respond to scalding water, are the two age categories that are most at risk for scalds: Adults may suffer third-degree burns if they are exposed to 150-degree water for even a brief period of time (as little as two seconds), according to the Consumer Products Safety Commission (CPSC).
In addition, burns can result with a six-second exposure to 140-degree water or a 30-second exposure to 130-degree water.
Will Changing the Water Heater Temperature Save Money?
The temperature at which you set your water heater can make a significant impact in the amount of electricity your home consumes. It is estimated that the water heater accounts for between 17 and more than 25 percent of your monthly energy bills, making it one of the most expensive single items on your home energy bill. Turning down your water heater temperature, according to the Energy Department, results in a considerable reduction in the expenses of standby losses, which are heat losses from your water heater into the surrounding region.
Reduced temperatures can result in more savings when doing duties such as washing clothing, taking showers, and dishwashing, among others.
What is My Water Heater Temperature?
You won’t be able to identify the temperature of most tank water heaters and some tankless water heaters merely by glancing at the temperature dial, because most are simply designated from “Low” to “Hot” (or “Very Hot”) on the dial. It is recommended that you consult your water heater’s handbook for the preset temperature. If you don’t know what you’re looking for, simply search the internet for the brand and kind of water heater you have, as well as the “default temperature.” However, the default temperature of the water heater is not always the same as the temperature of the water that is flowing out of your faucets.
Check the temperature of your tap water to be on the safe side.
How to Check Your Tap Water Temperature
- Avoid using your hot water for at least two hours before doing the test. If you have a tankless water heater, you can skip this step
- Otherwise, proceed as directed. Allow for a minimum of three minutes of running hot water. Make sure the temperature is correct by using a candy, meat, or water thermometer
- Set the temperature on your water heater’s thermostat to a more comfortable level. Continually repeat steps 2 and 3 until you get the required temperature. Wait for a full day to enable the water temperature to fluctuate before testing it once more. If you have a tankless water heater, you may skip this step.
Pro tip: Once you’ve found the temperature you desire, mark the location on the temperature dial of your water heater using a permanent marker.

What Temperature Should I Set My Water Heater?
Water heaters are a critically vital component of your house, but most homeowners don’t give them much thought once they’ve been installed in the first place. Unfortunately, installations completed before you moved in or by specialists who don’t take the time to ensure that the unit is running properly might result in incorrect water heater temperatures being reached. On the one hand, scorching hot water can be dangerous, while on the other, water that does not stay hot long enough to hinder the growth of hazardous germs can be quite dangerous.
Consider the following questions for yourself:
- Is it possible that the base temperature of the water heater has altered after it was initially installed? Water heaters used to be manufactured at a temperature of 140°F, which may induce scorching in as little as 5 seconds. Some heaters are set at a temperature of 160°F, which is far too high. A fraction of a second at that temperature will result in third-degree burns. Water heaters are now factory-set at 122.5°F, which is a much safer setting
- If the temperature has been adjusted, it is possible that the temperature has been set too low. A water temperature that is set too low is no more beneficial than a temperature that is set too high. Low temperatures, between 90 and 115 degrees Fahrenheit, might foster the growth of germs that can make you or your family very sick. It is necessary to prevent temperatures that are too low.
So What is the Best Water Heater Temperature Setting?
The majority of specialists think that the best temperature range for personal comfort and safety is 120°F to 125°F. Using this setting, you can prevent bacterial development while not having to worry about possible damage from being caused by hot temperatures. An additional benefit of decreasing the temperature is that you will save money on your energy costs. It’s also a good idea to spend some time getting acquainted with your water heater, which is often disregarded but is a vital component of your home’s plumbing system.
Water Heater Help from the Pros
For personal comfort and safety, most experts believe that a temperature range of 120°F-125°F is the most appropriate. Using this setting, you can prevent bacterial development while not having to worry about probable harm from being caused by the heat. Additionally, by reducing the temperature, you’ll be able to reduce your energy expenditures. Taking the time to double-check and verify that your water heater is set within a safe range of temperatures also allows you to become more familiar with this often-overlooked but vital component of your household.

How To Check Your Water Heater Temperature
The majority of water heaters do not have a temperature gauge with a digital readout on them. Temperatures or heating ranges are marked on thethermostat, rather than numbers. 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 OSHA-recommended temperatures, which are around 140 degrees. 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.
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
In case 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 possibly a tiny wrench or socket, the settings for gas water heaters are simple to alter. Always keep in mind that the thermostat is factory configured to a suitable temperature, and that adjusting it may increase the likelihood of catastrophic burns.
- Warm = 80-90°
- Low = 80-90°
- Hot (or triangle symbol) = 120°
- A= 130°
- B= 140°
- C= 150°
- Very Hot = 160°
- High = 120°
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. Installing a hot water recirculation system in a large house may be worth considering since it can reduce the amount of time it takes to heat water in all of the property’s outlets while also resulting in significant cost savings over the long term.
If setting the thermostat does not result in the desired temperature, it is possible that the water heater element has to be replaced. If you don’t notice a difference in the water temperature after adjusting the thermostat, it’s likely that the thermostat is broken and has to be replaced.
Adjusting Your Water Heater Settings: How To Maximize Efficiency
Not many people are aware that selecting the proper water heater settings may result in substantial savings. 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. Not only will it save you money, but it will also make your showering experience more pleasant as a result of it. Here is a breakdown of the procedures.
Default Hot Water Heater Settings Can Vary
Not many people are aware that choosing the proper water heater settings might result in substantial financial savings for them. Despite the fact that the majority of people don’t give your hot water heater settings a second thought, they are quite significant. Not only will it save you money, but it will also make your showering experience more pleasant as a result of this. The following are the procedures to be followed:
How Much Are Your Gas and Electric Hot Water Heater Temperature Settings Costing You?
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. That’s not too shabby after all! 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. “But hold on a minute,” you may be thinking. “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.
No matter what happens, raising the temperature is a simple process.
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 look at how to go about doing so.
Step One: Get An Accurate Temperature Reading
It’s likely that the thermostat dial linked to your water heater tank is not functioning properly. As a result, you should really use a thermometer to monitor the temperature of the water flowing out of your faucet. 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. 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
Finally, tankless water heaters are available. 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.
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
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. This may be accomplished simply turning off the necessary settings on your circuit breaker panel. Doing so is also recommended in the case of a gas water heater that consumes some power (as some newer units do). But hold on a minute! 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.
Some water heater temperature controls now include buttons that read “A-B-C” instead of numbers, which makes them easier to use.
To double-check these settings, consult the owner’s handbook for your water heater.
Step Four: Tweak the Settings as Necessary
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 how to do so. This may be accomplished simply turning off the necessary settings on your circuit breaker. a. Additionally, if you have a gas water heater that consumes some power, you should perform this task as well (as some newer units do). Hold on a second! What temperature should you choose as a starting point for your experiment?
Most of the things you do in your house should be warm enough with this setting.
As a rule of thumb, A represents 120 degrees, B represents 130 degrees and C represents 140 degrees in a given situation.
Frequently Asked Questions
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?
Yes, temperatures above 140 degrees Fahrenheit are uncomfortable for the majority of people. The only exception would be persons who require an additional layer of protection against germs, which cannot thrive in water at that temperature. 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.
