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.
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.
- Many people enjoy taking a hot shower, despite the fact that it is criticized by dermatologists for drying off their skin. In a household where hot water is fiercely competed for among family members, or even between your washing machine and dishwasher, you may be inclined to raise the temperature of your hot water heater to compensate. When is it too hot to be uncomfortable? Manufacturers and the Department of Energy hold opposing viewpoints. Scalding can occur at temperatures below 120 degrees Fahrenheit, although 140 degrees Fahrenheit is the standard setting. Any temperature below 120 degrees Fahrenheit, according to the majority of experts, increases the likelihood that bacteria from stagnant water, such as the bacterium legionella, which causes Legionnaire’s disease, would grow 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 to use. In order to properly adjust your thermostat, you need take into account the following factors:
But what about the expenses of energy? We get what you’re saying! Water heaters account for around 14-18 percent of the total energy consumed by a residence on a typical day. Furthermore, it may be tempting to lower the temperature in order to save money. It should be noted that a 10°F decrease in temperature is related with a 3-5 percent reduction in energy use. Legionella, on the other hand, can live at temperatures as high as 122°F. So be sure to strike a balance between your risk tolerance and your energy consumption objectives!
- Many hot water heaters are equipped with a temperature control dial.
- Start with 120°F and gradually increase the temperature in small increments until you get your desired result.
- 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.
- 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).
- Whatever you choose, we’re only a phone call away if you’re having issues with your hot water!

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
Is it getting old to burn your hands every time you turn on the hot water? What if you’re having trouble getting a comfortable water temperature, no matter how high you turn the faucet? However, they are not always indications of a problem with the water heater; instead, they indicate that the temperature setting may not be appropriate for your needs. It is possible for a water heater that has been installed incorrectly to have a significant influence on your life, even in ways that are not directly linked to plumbing.
As a result, it can have a negative influence on your health as well as the health of people who share your house with you.
A definitive or unambiguous response cannot be given; rather, part of it is a matter of individual choice.
Considerations When Choosing a Water Heater Temperature Setting
Do you have any at-risk individuals residing in your home? Those who are particularly sensitive to high temperatures may suffer serious consequences if they are exposed to overly hot water. Water at 150 degrees Fahrenheit may cause third-degree burns in newborn babies in only two seconds, while water at 140 degrees can cause third-degree burns in babies in just five seconds. Temperature reduction is more safer for your infant and far more cost-effective in terms of energy use. A water heater set at no more than 130 degrees is recommended if you have a baby or any youngster under the age of three in your household.
- 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.
- Do you have an appliance that is energy efficient?
- 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.
- 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.
- How many people do you have living in your house?
- Those who like a hotter shower increase the ratio of hot to cold water in their shower.
- The temperature of the water that comes out of your water heater, on the other hand, will have an impact on this as well.
- People that use cooler water heaters will require more hot water and less cold water in order to achieve their goals.
- 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.
Do you require assistance with your water heater in the Los Angeles area? Whether you want a thermostat replacement or the installation of a new water heater, contact the professionals at Moe Plumbing Services at (818) 396-8002 now.
More on Water Heaters:
- What if you have a family member or friend who is at risk? Heat-sensitive individuals, such as those with diabetes, can be badly harmed by very warm water. Water at 150 degrees Fahrenheit may cause third-degree burns in newborn neonates in just two seconds, while water at 140 degrees can cause third-degree burns in just five seconds. Temperature reduction is more safer for your infant and far more cost-effective in terms of energy usage. 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 home. Elderly households should adhere to the same guidelines and laws as everyone else, since they are also more susceptible to burning quickly and suffering potentially severe injuries if they are accidentally exposed to too hot water by mistake or by design. The temperature of the water should be raised for people with impaired immune systems or those who suffer from respiratory ailments in order to destroy microorganisms and increase the concentration of steam in the air while bathing, respectively. We propose a maximum water temperature of 140 degrees for these groups, assuming there are no smaller children present in the home at the time. Use an energy-efficient appliance in your home or business. Dishwashers that pre-heat are becoming more common these days. These systems take in water and then raise the temperature to even higher levels in order to provide an even better and more hygienic clean, and they do so without having you to raise the temperature coming from your water heater to achieve this result. 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 in to it. But if that won’t be for a long time, you could wish to raise the temperature of your water heater to 140 degrees Fahrenheit. 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 at any given time? Everyone has their own preferred shower temperature, but you can generally fine-tune this by turning the hot and cold water knobs back and forth. Hot water is used in greater quantities by those who want a warmer shower. Showers that are colder to the touch are preferred by those who like them to be cooler. Your water heater’s ability to heat the water will be influenced by the temperature of the water that comes out of the faucet. The hotter the water that comes out of your heater, the less hot water individuals will require, and the more cold water they will require, to attain their desired temperature. People will require more hot water and less cold water to attain their goal temperature with cooler water heaters. In other words, individuals who set their water temperature to a lower setting will find themselves running out of hot water more quickly. You should set your water temperature higher if you have a large home with several people living in it in order to extend the life of your hot water supply. The temperature can be set lower in smaller residences with fewer occupants since they are less prone to have power outages. In the Los Angeles region, do you require assistance with a water heater? Call the professionals at Moe Plumbing Services at (818) 396-8002 now if you need your thermostat updated or a new water heater installed.
What Temperature Should a Hot Water Heater Be Set At?
Do you have any people who are at risk of being harmed living with you? Overheated water can have a negative influence on people who are particularly sensitive to high temperatures. Water at 150 degrees Fahrenheit may cause third-degree burns in newborn babies in about two seconds, while water at 140 degrees Fahrenheit can cause third-degree burns in babies in five seconds. Bringing the temperature down is significantly safer for your infant, and it is also much better for your energy bills. 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.
- Those who have weakened 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.
- Do you have an appliance that is energy-efficient?
- These systems take in water and then raise the temperature to even higher levels in order to provide an even better and more hygienic clean, and they do so without asking you to raise the temperature coming from your water heater.
- If, on the other hand, it won’t be for a long time, you could wish to raise the temperature of your water heater to 140 degrees.
- How many people do you have living in your home?
- Those who like a hotter shower increase the proportion of hot to cold water in their shower.
- The temperature of the water that comes out of your water heater, on the other hand, will have an impact on this.
- People that use cooler water heaters will require more hot water and less cold water in order to achieve their goal.
- The water temperature should be raised if you have a large home with multiple people living in it, as this will help to extend the life of your hot water supply.

Factors That Affect Hot Water Temperature Setting
Do you have any at-risk individuals living with you? Water that is excessively hot might have a negative influence on persons who are particularly sensitive to high temperatures. For small newborns, it only takes two seconds of exposure to water at 150 degrees Fahrenheit to create third-degree burns, and it only takes five seconds at 140 degrees to cause third-degree burns. Bringing the temperature down is significantly safer for your infant, and it is also much better for your energy expenditures.
- Elderly homeowners should adhere to the same guidelines and laws as everyone else, since they are also more susceptible to burning quickly and suffering potentially painful injuries if they are accidentally exposed to too hot water.
- If there are no younger children in the house, we recommend keeping the water temperature no higher than 140 degrees for these groups.
- Pre-heating dishwashers are becoming increasingly common.
- When it comes time to update or replace your dishwasher, we strongly advise that you search for one that includes a pre-heat system.
- This will maintain the water nice and hot for your dishwasher while still remaining safe to use for the majority of your family members, providing you use enough cold water to compensate.
- Everyone has their own preferred shower temperature, but you can generally fine-tune this using the hot and cold water knobs.
- Those who like their showers to be colder utilize a lower ratio.
- If the water that comes out of your heater is hotter, individuals will require less of it and more cold water to achieve their preferred temperature.
- As a result, those who set their water temperature lower will find themselves running out of hot water more quickly.
- Smaller homes with fewer occupants may get away with a lower thermostat setting since they are less likely to run out of heat in the first place.
Need assistance with your water heater in the Los Angeles area? Call the specialists at Moe Plumbing Services at (818) 396-8002 now if you need your thermostat updated or a new 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
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 set at. Allow for a few minutes of continuous running of the hot water tap before measuring the temperature.

What Is The BEST Water Heater Temperature Setting?
Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. If you have already set the temperature and are thinking to yourself, “I don’t have any hot water,” or “I don’t have enough hot water,” there are a few variables that might be causing the problem. If all else fails, it’s possible that the heating element is faulty and has to be replaced.
How To Check Your Water Heater Temperature
The majority of water heaters do not have a temperature gauge with a digital readout on them. 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.
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.
Recommendation from me Water heaters should be adjusted to 130 degrees Fahrenheit, in my opinion, in practically all circumstances. However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.
How To Turn Up Your Water Heater
Water heaters are pre-programmed to operate at OSHA-recommended temperatures, which are around 140°F. In contrast, the Environmental Protection Agency recommends lowering the thermostat down to 120 degrees F to save energy use and using a booster heater to attain sanitizing temperatures at certain outlets. A different 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. What I Would Suggest Water heaters should be adjusted at 130 degrees Fahrenheit, in my opinion, in virtually all situations.
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:
- The temperature of a gas water heater may be adjusted by turning a control knob on the unit. For the most part, gas control valves are labeled A-B-C on the knobs that are on them. Control valves for gas water heaters may be labeled differently depending on their manufacturer. Generally speaking, the following is what each label signifies:
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
There is a “Vacation” setting available on occasion. However, the water will not be heated as a result, but the pilot light will remain lit.
Factors That Affect Water Temperature
There is occasionally a “Vacation” setting available. This does not heat the water, but it does keep the pilot light up.
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
You might be wondering what temperature to put your water heater at. A water heater unit is normally pre-programmed when it is purchased from the manufacturer. However, this does not preclude you from being able to regulate the temperature of the machine. Good news: you have the ability to choose a comfortable temperature for your family while yet ensuring their safety. A few weeks ago, we wrote an article about how your shower’s temperature might suddenly fluctuate. For example, a malfunction with your water heater is one of the possible causes.
Although the temperature of the device is important, it can have an impact on how well it performs. In this article, we will discuss the dangers of setting your water heater’s temperature too high or too low, as well as the optimal temperature for it to perform efficiently.
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.
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
Warning: Using a water heater with the temperature set too high will cause your energy cost to rise! According to the Department of Energy, standby heat losses from your water heater can cost you anywhere from $36 to $61 per year in energy savings. The good news is that by lowering your thermostat, you may save anywhere from 4 percent to 22 percent on your annual energy expenditure. Lowering the temperature of your water heater can help to decrease standby heat loss, which is one of the reasons you have a high energy cost.
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
If you want to save money on energy costs, you should avoid setting the temperature of your unit too low. It is possible that you will have a health problem as a result.
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
The optimum temperature is. What several agencies have to say about the optimal temperature is summarized below: According to the Occupational Safety and Health Administration (OSHA) and the World Health Organization (WHO), water heaters kept below 60 degrees Celsius (140 degrees Fahrenheit) may promote Legionella development. This temperature, on the other hand, will almost certainly increase the likelihood of being burned by searing hot water. If you have young children at home, the Centers for Disease Control and Prevention (CDC) and the Energy Department recommend that you set your water heater’s thermostat to 120°F or lower.
This will help you keep control over the water temperature throughout your home, preventing it from being overly hot.
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.

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.
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. Then, to get an accurate reading, place a thermometer beneath the surface of the water.
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 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.

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.
It’s conceivable that you won’t even notice a difference. No matter what happens, raising the temperature is a simple process. It has the potential to cause aging hotwater 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 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
When using an electric water heater, you must change the hot water settings at the top and bottom of the tank to your preference. Both controls, which are often concealed behind a panel and comprise of knobs that you crank to establish the correct electric water heater thermostat settings, are typically located on the same side of the heater.
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
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
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.

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.
Best Temperature for a Water Heater
Your hot water heater settings are most likely remain at the factory default temperature of 140 degrees if you haven’t changed them in a long while. 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 temperature.
Determine the Best Temperature for Your Water Heater
The usual setting for most water heaters is 140 degrees Fahrenheit, but the Department of EnergyLink opens in a new tabrecommends lowering the temperature to 120 degrees Fahrenheit in order to conserve energy. To summarize, you shouldn’t drop the temperature of your tank below 120 degrees because doing so encourages bacteria development (unless you are traveling out of town, in which case the DOE suggests lowering the temperature to its lowest level). Consider the following factors that influence the temperature at which you should set your water heater:
- 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
Water heater at 140 degrees: If your dishwasher does not have a booster heater, you may want to maintain your water heater at 140 degrees to ensure that it cleans the most effectively. Modern dishwashers, on the other hand, are equipped with this capability by default. For further information, consult your owner’s handbook. In terms of your physical well-being, While bacteria growth in a tank at 120 degrees is generally considered safe for most individuals, those with a compromised immune system might consider maintaining their tank at 140 degrees.
The extra 20 degrees, on the other hand, can assist ensure that everyone has hot water when six family members shower back-to-back each morning.
This is especially significant if you have children or elderly people living with you.
- 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.

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.

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?
The only time you give your water heater any thought is when it fails to provide enough hot water when you are taking a shower. Another possibility is that the water is overly hot and blistering occurs. The temperature of your water heater is adjustable, but is it really necessary? You would imagine that water heaters have a standard suggested temperature, but that’s just not the case. A temperature of 120°F (49°C) is factory-set on certain water heaters, whereas a temperature of 140°F (60°C) is factory-set on others.
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 germs in the work environment.
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.
In addition, burns can develop after a six-second exposure to 140-degree water or a 30-second exposure to 130-degree water. 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 question then becomes, how do you balance the hazards of bacteria development with potential scalding? Anti-scald guards and devices are normally installed in newer homes, but if you live in an older home, you may install anti-scald guards and devices in showerheads and tub spouts to help prevent dangerously hot water from escaping. Consult with a plumber about installing a thermostatic mixing valve (also known as a tempering valve or an anti-scald valve), which restricts the maximum temperature that may be discharged from your hot water heater.
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.
How to Check Your Tap Water Temperature
- If you look at the temperature dial on most tank water heaters and some tankless water heaters, you won’t be able to know what the temperature is since most of them are simply designated from “Low” to “Hot” (or “Very Hot”). It is recommended that you consult your water heater’s handbook to find out what its preset temperature is. If you don’t know what brand and kind of water heater you have, simply search the internet for the “default temperature” of that particular model. The default temperature of the water heater, on the other hand, is not always the temperature of the water that comes out of your faucets. Check the temperature of your tap water to be on the safe side of things.
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.
Find the Right Water Heater Temperature
Using a permanent marker, mark a point on your water heater’s temperature dial when you have reached the temperature you desire. Pro Tip:
Home Warranty Coverage for Water Heaters
Maintenance of your water heater on a regular basis can assist to prevent malfunctions and may even help to increase the lifespan of the equipment. In certain cases, even the most attentive maintenance will not be enough to avoid the onset of a problem with your water heater.

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°.
- 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:
- A large family necessitates greater water use
- The water that comes out of the dishwasher does not pre-heat
- A resident at home has a weaker immune system or is suffering from a respiratory ailment.
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. Alternatively, if you believe the temperature is not adjusting effectively, contact a plumber who specializes in water heater problems.
