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
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.

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.
- Use 120°F if you have small children or the elderly in your house who are prone to third-degree burns in seconds, or if you are the sole inhabitant of your home since there is less demand for hot water. Consider 140°F if you have an immunocompromised individual in your house, a dishwasher that does not pre-heat, or if you have a large number of occupants owing to the increased need for hot water.
But what about the expenses of energy? We get what you’re saying! Water heaters account for around 14-18 percent of the total energy consumed by a residence on a typical day. Furthermore, it may be tempting to lower the temperature in order to save money. It should be noted that a 10°F decrease in temperature is related with a 3-5 percent reduction in energy use. Legionella, on the other hand, can live at temperatures as high as 122°F. So make sure to strike a balance between your risk tolerance and your energy consumption targets!
- 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!
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.
Owners of dishwashers that do not pre-heat the water may wish to set their water heater temperature to 140 degrees; elderly homeowners or those with young children may want to maintain 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”; Homes with residents who have a weakened immune system or respiratory problems should maintain the hot water temperature set at 140 degrees Fahrenheit.
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 the permitted range.
If you want to save money, every 10 degrees you lower the water tank thermostat, you save between 3 and 5 percent on your energy bill.
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. 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 properly.
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.
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.

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
If you are dissatisfied with the suggested temperature of your hot water heater, you may alter the settings to receive extra hot water. Although electric water heaters may require a screwdriver and potentially a tiny wrench or socket, most hot water heater settings are straightforward to modify. Keep in mind that the thermostat is factory configured to a recommended temperature, and that altering the setting may increase the risk of significant burns from the appliance.
How to Set Temperature on a Gas Water Heater
The temperature of a gas water heater may be adjusted by turning the setting knob on the water heater. The majority of gas control valves have a knob with different designations on them, such as A-B-C. Control valves for gas water heaters may be labeled differently depending on the manufacturer. In the majority of circumstances, the following is what each label indicates:
- 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
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 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.
How to Adjust Your Water Heater’s Temperature
The distance between the water heater and the outlet, the way the pipes are installed, and the state of the heating element are all factors that might impact the temperature of your hot water. The time it takes for hot water to reach the entrance of a small bore pipe or across a long distance will be longer, for example, and pipes that run under or outside the residence may be vulnerable to different temperatures in the winter and the summer. Installing a hot water recirculation system in a large house may be worth considering since it may reduce the amount of time it takes to heat water in all of the house’s outlets while also resulting in significant cost savings over the long haul.
Alternatively, if you don’t observe any variation in water temperature after adjusting the thermostat, it’s conceivable that you have a broken thermostat that has to be repaired.
- 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.
What is the optimal temperature to set the water heater at? That is a question that many homeowners have. Previous PostNext Post This is a fantastic question, and the information provided by Aire Serv® will help you to enhance the performance, efficiency, and safety of your water heater by following the guidelines.
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:
- The normal 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. Just remember that any temperature setting below 120 degrees encourages bacteria growth within the tank, so you shouldn’t go any lower than this (unless you’re traveling out of town, in which case the DOE suggests putting the thermostat down to the lowest level). Keep in mind these factors that influence the temperature at which you should operate your water heater:
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.
Other Ways to Improve Water Heater Efficiency
In addition to lowering the thermostat, you may make these energy-saving modifications to your residence. To lower your water heating expenses, click on the following link, which will open in a new tab:
- Insulate the water heater tank to decrease heat loss during standby mode. Renovate your bathroom by replacing your showerheads and faucets with low-flow models that use less hot water. Replace your existing water heater with a tankless one that warms water on demand, eliminating the need for storage and the accompanying standby heat loss.

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 temperature
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
A chilly shower is not something anybody enjoys taking. When you turn on the hot water, it is even worse since you will get scalded.
Correctly regulating the temperature on your water heater is critical not only for your health and safety, but also for saving money on your power bill. You may save money and protect your skin by adjusting the temperature of your water heater.
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.

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 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.
Check the temperature of your tap water to be on the safe side.
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
Your water heater’s “optimal” temperature is essentially a matter of personal preference – for your own level of comfort, any potential safety problems, your monthly utility cost, and energy efficiency considerations.

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.
