How To Check Your Water Heater Temperature
The majority of water heaters do not have a temperature gauge with a digital readout on them.A temperature or heating range is marked on the thermostat, rather than a number.A cup and a culinary thermometer will be required in order to correctly determine the temperature of the hot water heater.If you haven’t used your water heater in at least one hour, turn on the faucet that is nearest to it.Allow the water to run for at least one minute to ensure that the water is at its warmest possible temperature before filling the cup with it.
- Insert your cooking thermometer and make any necessary adjustments to the temperature settings.
Recommended Temperature Settings
Water heaters are pre-programmed to operate at temperatures about 140 degrees Fahrenheit, which is recommended by OSHA.The Environmental Protection Agency, on the other hand, recommends lowering the thermostat down to 120 degrees Fahrenheit to save power use and using a booster heater to attain sanitizing temperatures at certain outlets.Another point of view is that lower temperatures are preferable for homes with little children, although higher temperatures are more effective in cleaning and sanitizing surfaces.Recommendation from me Personally, I feel that the temperature of a water heater should be set around 130 degrees in practically all circumstances.However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.
How To Turn Up Your Water Heater
If you are dissatisfied with the suggested temperature of your hot water heater, you may alter the settings to receive extra hot water.Although electric water heaters may require a screwdriver and potentially a tiny wrench or socket, most hot water heater settings are straightforward to modify.Keep in mind that the thermostat is factory configured to a recommended temperature, and that altering the setting may increase the risk of significant burns from the appliance.
How to Set Temperature on a Gas Water Heater
- The temperature of a gas water heater may be adjusted by turning the setting knob on the water heater. The majority of gas control valves have a knob with different designations on them, such as A-B-C. Control valves for gas water heaters may be labeled differently depending on the manufacturer. In the majority of circumstances, the following is what each label indicates: Temperatures range from 80-90 degrees
- hot (or triangle sign) = 120 degrees
- A = 130 degrees
- B = 140 degrees
- C = 150 degrees
- Very Hot = 160 degrees
There is a ″Vacation″ setting that appears from time to time. This does not heat the water, but it does ensure that the pilot light remains lit.
How to Set Temperature on an Electric Water Heater
Turn off the circuit breaker if necessary. Remove the access panels from the room. Under the insulation, look for the thermostat adjustment screwhole. Adjust the thermostat control to the appropriate temperature by using a straight screwdriver to make the adjustment. After replacing the insulation and panels, the power should be restored. Here’s a good video that demonstrates the procedure:
Factors That Affect Water Temperature
Some of the things that may influence the temperature of your hot water include the distance between the water heater and the outlet, the way the pipes are built, and the quality of the heating element itself, among others.Because of the length of the pipe and the small bore size, it will take longer for the hot water to reach the opening.Additionally, pipes that run beneath or outside the residence may be exposed to freezing or freezing temperatures in the winter and summer.If you have a big house, you may want to consider installing a hot water recirculation system, which may reduce the amount of time it takes to send hot water to all of the outlets in the house, as well as provide significant cost savings over time.If setting the thermostat does not result in the desired temperature, it is possible that the water heater element has to be replaced.
- Alternatively, if you don’t notice a difference in water temperature after changing the thermostat, it’s likely that you have a malfunctioning thermostat that has to be replaced.

What Temperature Should Hot Water Be at the Tap?
So, before we go into the nitty-gritty of the maximum settings, let’s address the question ″what is the optimal temperature for residential hot water?″ You’ll know exactly what temperature you should be aiming for when you’re in the shower.It’s crucial to consider two things when determining the appropriate temperature: how hot water can be before scorching you and how cold water can be before bacteria starts to thrive.Let’s take these variables one by one.
Water Temperatures vs. Bacteria
As the temperature of the water rises, bacteria have a lesser chance of surviving.The amount of bacteria present in the water will be influenced by the temperature of the water in question.At temperatures more than 158 degrees Fahrenheit, all bacteria will die almost rapidly, if not immediately.At somewhat lower temperatures of 140 degrees Fahrenheit, bacteria will die within 2 minutes, with around 90% of them dying within 2 minutes.Bacteria can survive and multiply at temperatures ranging from 118 to 122 degrees Fahrenheit from there.
- Finally, bacteria can survive at temperatures ranging from 90 to 108 degrees Fahrenheit, providing the ideal setting for survival.
- Knowing these temperature ranges can assist you in determining whether or not germs will be able to survive in your hot water.
Water Temperatures vs. Scalding
While it is necessary to heat water in order to kill germs, it is equally crucial not to overheat the water.Hot water burns might result if you don’t take precautions.According on how long you are exposed to the water, the temperature of the water will cause burns on your skin.Burns will result with prolonged exposure to temperatures above 120 degrees Fahrenheit for more than 5 minutes.Temperatures of 130 degrees Fahrenheit produce burns in 30 seconds or less if not treated immediately.
- When the temperature is 140 degrees Fahrenheit, you can be burnt in around 5 seconds.
- Burns occur in around 1.5 seconds at temperatures of 150 degrees Fahrenheit.
- It is critical to keep the temperature of the hot water below a certain threshold in order to avoid burns.
What Is the Maximum Temperature for a Hot Water Heater
In order to avoid burns and to keep bacteria at away, you must know how hot the water must be before using it.What is the hottest temperature that your water heater can be adjusted to, on the other hand?The most common belief is that the highest temperature for a hot water heater is 120 degrees Fahrenheit.This manner, you may safely avoid burns while also reducing the spread of microorganisms in the water supply.
Keep Your Water Heater Temperature Range at the Right Settings
As a result, you now understand what the optimal water heater temperature range is.Typically, a thermometer or a gauge mounted on the side of the machinery may be used to easily determine the proper hot water temperature for a certain application.By following the recommendations in this guide, you will be able to ensure that your hot water is at the appropriate temperature.You will be able to take a safe and enjoyable shower without causing any damage to yourself or your property in this manner.Please contact the professionals at All A’s Plumbing and Heating if you require assistance with your hot water heater.

- Let’s get this party started!
What Is the Ideal Water Heater Temperature?
- What is the appropriate temperature for a water heater? The following temperature settings are available on the majority of gas water heaters: Low (Warm): 80-90°F
- Hot (Triangle symbol): 120°F
- A: 130°F
- B: 140°F
- C: 150°F
- Very Hot: 160°F
- Low (Warm): 80-90°F
- Very Hot: 160°F
- Low (Warm): 80-90°F
- Low (Warm): 80-90°F
- High (Triangle symbol): 120°F
- A: 130°F
- B: 140°F
In most cases, electric water heaters have the temperature settings printed out on the thermostat, and you must use a screwdriver to modify the temperature setting on the thermostat.
The Ideal Water Heater Temperature
While everyone has their own temperature preferences, the majority of people believe that a temperature of around 130 degrees Fahrenheit is the best water heater temperature for both gas and electric water heaters, regardless of their source of heat.It is recommended that you use a water heater that operates between 120°F and 140°F, based on your personal tastes and hot water requirements.Your water heater was most likely installed with the temperature set at 140 degrees Fahrenheit, which is the OSHA-recommended setting for water heaters.
Why 140 Degrees?
Although the water is hot enough to sterilize and inhibit bacterial development at 140 degrees, it has the potential to scald anyone who is exposed to it for more than 6 seconds.As a result, we propose that you reduce the temperature of your water heater to 130 degrees.This is hot enough to prevent hazardous germs from forming in your water heater, but not too hot to cause scorching to anybody who comes into contact with it.If energy economy is a consideration in your selection, the Environmental Protection Agency (EPA) recommends a 120-degree temperature setting for your refrigerator.
The Environmental Protection Agency (EPA) suggests raising the temperature to 120 degrees since it consumes less energy while yet being warm enough to be comfortable.It will not, however, destroy germs and will instead provide an environment in which hazardous bacteria can develop in your water heater.Maintaining the proper temperature setting should take into account any hot water appliances in your house that may require higher temperatures in order to sanitize efficiently.However, while 120 degrees is a lovely temperature for hot water, it is not hot enough to sterilize dishes or wash clothing.
Water Heater Temperatures Compared
- Here’s a comparison of the many optimal water heater temperature settings, as well as their advantages and disadvantages: 120°F: The most energy-efficient and scald-safe temperature, but it will not disinfect or kill bacteria, and it will enable bacteria to multiply.
- The temperature of 130 degrees Fahrenheit is comfortable, relatively energy-efficient, and scald-safe
- it destroys germs in 6-8 hours and does not enable bacteria to proliferate
- A temperature of 140°F is extremely hot, making it perfect for sanitization and germ destruction, yet it has the ability to scald in less than 6 seconds
- The temperature of 150°F is extremely high, making it suitable for sanitization and germ destruction, but it will scald in less than 2 seconds.
- 160°F: The highest temperature setting available on most gas water heaters, which is perfect for sanitization and germ killing, but which can scald anybody who comes into touch with it
If you like to have the best of both worlds, you may choose between two alternatives.As a starting point, you may try adjusting the water heater temperature to 130 degrees, which is hot enough to sterilize but not hot enough to scald.In addition, you can make use of a hot water tank booster.As a result, although the water in the tank remains at a bacteria-killing 140 degrees, it is mixed with enough cold water from the faucet to reduce the temperature to a safer, more pleasant 120 degrees.
Things to Consider When Setting Water Heater Temperature
- If you have small children or elderly individuals living in your home, consider decreasing the water temperature to 120°F to prevent the danger of scalding.
- If you have a dishwasher that does not pre-heat the water, you should consider boosting the temperature of the water heater to 140°F.
- • If there is someone in the home who is immunocompromised, consider boosting the water heater temperature to 140°F to eliminate the possibility of bacteria growing in the water supply
- If you’re wanting to save money on your energy bills, every 10 degrees Fahrenheit you reduce the temperature of your water heater, you’ll save around 3-5 percent on your monthly energy bills. Maintain a water heater temperature at the upper end of the optimum range (about 140°F) if you have four or more persons in your family to guarantee that there is enough hot water available to fulfill the additional demand.
Is Your Water Heater Temperature Too Low?
It’s likely that your water heater has a thermostat that you can change, but it doesn’t have a digital display that shows the actual temperature. So, how can you determine whether or not the temperature of your water heater is too low? There’s a straightforward way to find out:
- Take a heat-resistant cup and a cooking thermometer with you. Avoid using the hot water for at least one hour (and ensure that no one else in the house does as well)
- Fill the cup halfway with hot water by turning on the hot water faucet nearest to the water heater for approximately a minute to allow it to reach its maximum temperature.
- Pour boiling water into a measuring cup and insert your cooking thermometer to measure the temperature.
It is necessary to change the thermostat if your hot water is less than 120°F in order to bring it up to a temperature that is suitable for drinking.
Why Low Water Heater Temperatures Are Dangerous
Legionella bacteria are naturally occurring in freshwater and are the primary source of concern when water temperatures are too low.Legionnaires’ illness is caused by a kind of bacterium known as Legionella.If water heaters are not maintained at the proper temperature, they can become a breeding ground for this hazardous bacterium.Generally, Legionella flourishes in water with temperatures between 77°F and 108°F, although it may live in water with temperatures as high as 120°F.The bacteria Legionella can survive at water temperatures as high as 120°F, however at that degree, the bacteria is prevented from reproducing and multiplying.
- The risk of getting sick from drinking polluted water is higher for those who already have an impaired immune system, such as seniors over 50, people who have a chronic condition, and current and previous smokers.
- As a result, it’s preferable to keep the temperature at or above 140°F to guarantee that the water is hot enough to completely kill the germs.
Is Your Water Heater Temperature Too High?
- In your house, if you’ve had to jump back or take your hand from the hot water, it’s most likely because the water is too hot. If you want to acquire an accurate reading of the water temperature, use this method. The temperature of the water should be tested using a heatproof cup and a calibrated cooking thermometer. For at least one hour, refrain from using hot water. Alternatively, perform this test first thing in the morning before anybody else uses hot water. Step 1: Locate the faucet that is closest to the water heater and turn on the hot tap, allowing it to flow for a full minute to reach the desired temperature. Fill the cup halfway with hot water, and then use your kitchen thermometer to check the temperature of the water. If the temperature rises above 140 degrees Fahrenheit, you may wish to lower the temperature setting to 120°F-140°F. Water that is too hot might be harmful. It has the potential to scald and burn flesh, sometimes immediately upon contact if the water is sufficiently hot. If you have non-immunocompromised small children or elderly people in your house, or if you wish to save as much energy as possible, choose 120°F.
- 130°F is the temperature to use if you want pleasant water that is not conducive to hazardous Legionella bacteria but is still hot enough to sanitize.
- If you have immunocompromised home members, if you have more than four household members, or if your dishwasher does not pre-heat the water it uses, choose 140 degrees Fahrenheit.
How to Adjust Water Heater Temperature
Following your discovery of the optimal water heater temperature, it is time to make the necessary modifications. Adjusting the temperature of a water heater is simple, but the procedure differs significantly depending on whether the water heater is electric or gas. Instructions for both are provided below.
How to Adjust Electric Water Heater Temperature
- Circuit breakers should be used to turn off the electricity to an electric water heater.
- Locate the access panel on your water heater that covers the thermostat or thermostats. Using a screwdriver, pry the panel away from the wall.
- When removing the insulation from around the thermostat, use gloves.
- Manually adjusting the thermostat temperature setting may be accomplished using a flathead screwdriver. You should be able to see the different temperatures listed on the thermostat, so simply turn the dial in the direction you want the temperature to be adjusted.
- If your water heater has two thermostats, adjust the top thermostat by the same amount as you did the lower thermostat. You might even set the top thermostat to be slightly higher than the lower thermostat in order to guarantee that both heating components within the tank are utilized equally.
- Replace the insulation that was removed and screw the access panel for one or both thermostats back into place.
- Restore electricity to the water heater by resetting the circuit breaker.
- After a few hours, check the water temperature to make sure it has reached the proper degree.
If the temperature of the water does not rise or decrease to the desired level within 3-4 hours, you should contact a professional to inspect your water heater.Your thermostat or another component within the tank may be malfunctioning, which is preventing the water from heating up properly.Before the expert comes out to look at it, you should refrain from making any more alterations to the vehicle.
How to Adjust Gas Water Heater Temperature
- Locate the dial on the side of your gas water heater that controls the temperature. A detachable access panel may be included on vintage water heaters, allowing you to get to it. Newer water heaters may have this information printed right on the outside of the tank.
- Remove the access panel (if your water heater’s thermostat is hidden behind one) by prying it open with a screwdriver.
- Increase or decrease the temperature setting on the thermostat dial. Remember:
- ″Low″ temperature is 80-90°F
- ″Hot″ temperature (or triangle sign) is 120°F
- ″A″ temperature is 130°F
- ″B″ temperature is 140°F
- ″C″ temperature is 150°F
- ″Very Hot″ temperature is 160°F
Replacing the water heater’s access panel (if it was removed) and waiting a few hours before testing the water temperature to ensure it was appropriately adjusted
- If the temperature of your water heater does not reach the level you have set it to within a few hours, you should contact a professional to come and inspect it.
- It is possible that there is a problem with the water heater’s components or with the gas supply that drives the water heater.
- Before the specialist arrives to examine the water heater, refrain from making any further alterations to it.
Find Your Ideal Water Heater Temperature
- The appropriate water heater temperature will vary depending on your own tastes and the demands of your home. In order to determine the optimal water heater temperature for your home, you need take into account all of the factors listed below: Members of the household range in age from: Young children and the elderly, who are not immune impaired, may be more susceptible to scorching than others. Set the temperature to 120 degrees Fahrenheit
- Health of members in the household:
- Any person suffering from a chronic illness or having a damaged immune system need water heated to 140°F in order to destroy any Legionella bacteria in the water heater
- use a hot water booster to maintain the water at 140°F, but mix it with cold water at the tap to avoid the danger of scorching
- Families with four or more members often have a higher need for hot water
- thus, set the temperature to 140°F in order to guarantee there is adequate hot water available.
- Temperature reduction for greatest energy savings: If you’re attempting to cut your energy bills, lower the temperature to 120°F for best savings, or lower it by 10°F from a higher setting. For every 10°F reduction in temperature, your energy expenses reduce by 3-5 percent.
- Dishwashers that do not pre-heat the water to a high temperature: If you have a dishwasher that does not pre-heat the water to a high temperature, set the temperature to 140°F to guarantee that the water is sufficiently hot to sanitize
When you take all of these factors into consideration, you’ll discover that your optimal water heater temperature is anywhere between 120°F and 140°F. If all else fails, start with a temperature of 130°F and progressively increase or decrease the temperature to suit your comfort level and requirements.

What Temperature Should I Set My Water Heater At?
11th of March, 2020 Get in Touch With Us
Setting the Ideal Hot Water Heater Temperature
- 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.
- In the case of a water heater, which consumes around 18 percent of the energy in your house, changing it by just 10 degrees can result in a three to five percent reduction in your monthly energy bill.
- It can also have a negative influence on your health or the health of people who share your home with you.
- How do you set your thermostat when there is so much riding on the outcome?
- A definitive or simple response cannot be given; rather, part of it is a matter of personal choice.
- But there are a few guidelines you may follow to ensure that your temperature setting is optimal for you.
General Recommended Water Heater Temperature
- You can find out what temperature water should be at by visiting the Environmental Protection Agency.
- The optimum 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.
- Some homes will require it to be even hotter than this for a variety of reasons that we shall address shortly, but exercise caution when exceeding this temperature threshold.
Considerations When Choosing a Water Heater Temperature Setting
- 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.
- It only takes two seconds of exposure to water at 150 degrees Fahrenheit to create third-degree burns in small neonates, and only five seconds at 140 degrees to cause third-degree burns.
- 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.
- Elderly homeowners should follow the same guidelines and laws as everyone else, because they are also at risk of burning quickly and suffering potentially painful injuries if they are accidentally exposed to too hot water.
- Those who have compromised immune systems or who suffer from respiratory ailments, on the other hand, may benefit from a hotter water temperature in order to destroy bacteria while also increasing the concentration of steam in the air when bathing.
- When dealing with these people, and assuming there are no smaller children around, we recommend keeping the water temperature no higher than 140 degrees.
- Do you have an appliance that is energy efficient?
- Dishwashers that pre-heat are becoming increasingly common.
- Essentially, these systems take in water and then raise the temperature to even higher levels to provide an even better and more hygienic clean, all without the need for you to raise the temperature coming from your water heater.

What Temperature Should a Hot Water Heater Be Set at?
- What temperature should a hot water heater be set at?
- Do you have the same question as many other people?
- Setting the water heater to the proper temperature is critical for providing not just more pleasurable showers, but also longer showers.
- It also protects individuals from contracting infections.
- This page provides answers to your most often asked questions about the optimal hot water temperature.
- We’ll also go through some of the considerations you should keep in mind while adjusting the heater’s thermostat.
- Let’s get this party started.
What is the Ideal Temperature Setting of a Water Heater?
- There are two schools of thinking that can throw light on the topic of what temperature should be set for a water heater.
- Water heater manufacturers set the temperature of their water heaters to 140 degrees Fahrenheit by default, believing that the temperature is more calming and pleasant for the majority of people.
- According to the Occupational Safety and Health Administration, this water heater setting should be used to prevent the growth and multiplication of Legionella and other dangerous germs in water heaters.
- According to the Mayo Clinic, Legionella bacteria may be found in both water and soil as non-infectious agents that do not cause disease.
- In contrast, when these bacteria multiply in water systems, such as those found in air conditioning units and household plumbing, they have the potential to become harmful.
- People become infected with Legionella bacteria when they inhale water droplets containing the bacteria when showering or utilizing whirlpools, hot tubs, water heaters, or hot water tanks.
- Alternatively, the United States Department of Energy and the Environmental Protection Agency have determined that the optimal water temperature is 120 degrees Fahrenheit (or below).
- Medical and healthcare professionals have also chimed in on the controversy, advising that the hot water heater temperature setting should not be lower than 120 degrees Fahrenheit in order to avoid microbial development in the water heater.
- The position of the Consumer Product Safety Commission, which recommends a maximum water temperature of 120 degrees Fahrenheit for safety reasons, further complicates the situation.
- According to the organization, hot water (over 120 degrees Fahrenheit) might induce burn injuries in persons who are vulnerable to them.
- The recommended temperature of 120 degrees Fahrenheit is likely to be appropriate for most people’s households.
Unfortunately, no two families or homes are comparable in their characteristics.As a result, it would be wise to analyze the role that various components play in the overall equation.
What Factors Should You Consider When Setting the Water Heater’s Thermostat?
People have varying opinions on what temperature hot water should be at the optimal time of day. It’s possible that I favor 120 degrees, while you or other individuals could prefer 130 or 140 degrees. Regardless of the sort of water heater you have, it is recommended that you take the following aspects into consideration.
- In accordance with the American Burn Association, children under the age of 16 account for 26 percent of all admissions to burn treatment facilities.
- According to the organization, younger children are more susceptible to scorching injuries because of their weak cognitive and physical abilities, as well as a lack of parental supervision when using hot water, among other factors.
- Young children also lack the ability to perform self-rescue maneuvers.
- Because of pre-existing medical issues, slower response time, and decreased mobility, the elderly are particularly vulnerable to hot water-related burn injuries.
- In addition, as compared to other age groups, both children and the elderly have smaller skin layer thicknesses.
- Even when exposed to hot water for a short period of time or when the water temperature is modest, they might sustain severe burn damage.
- According to the American Burn Association, three seconds of exposure to 140-degree Fahrenheit water is all it takes to create major burn injuries that necessitates surgical intervention.
- Because of this, you could believe that a hot water heater setting of 140 degrees Fahrenheit is safe for you.
- You must, however, lower the temperature in your home to 120 degrees Fahrenheit if you have children or elderly members of your household.
Immune System Functioning
- We require a properly functional immune system in order to defend ourselves against infections.
- Whenever an organism infiltrates our body, the immune system mobilizes an army of defense cells to combat the invasion.
- Because immune-compromised individuals no longer have a powerful defense army in their bodies, they are more susceptible to infection than the general population.
- Increased water temperatures may be required to destroy germs in those who have lowered immune system capabilities.
- People who use immunosuppressive drugs are unable to protect themselves against infections.
- In addition to corticosteroids, monoclonal antibodies and biologics, and calcineurin inhibitors are examples of immunosuppressive medications.
- People suffering from HIV/AIDS, psoriasis, Crohn’s disease, rheumatoid arthritis, and lupus are all affected in the same way.
- Patients undergoing organ transplant procedures also have compromised immune systems, which makes them more susceptible to infection than the general population.
- In houses with immunocompromised individuals, 140 degrees Fahrenheit is the best temperature for domestic hot water to be provided.
- While certain bacteria are thermophilic or heat-resistant, the vast majority of them cannot endure temperatures beyond 140 degrees Fahrenheit.
- Even the deadly Legionella bacteria will perish at 122 degrees Fahrenheit (50 degrees Celsius).
Unfortunately, certain heat-resistant viruses must be inactivated at temperatures greater than 140 degrees Fahrenheit in order to be killed.Families with immunocompromised individuals should adjust the water heater temperature to 140 degrees Fahrenheit, regardless of the reason.
- According to the United States Department of Energy, adjusting the water heater to 120 degrees Fahrenheit can result in yearly energy savings ranging from 4 percent to 22 percent.
- It is estimated that the savings will come from lower demand losses (at least $400 per year) as well as lower standby losses (between $36 and $61 per year).
- When it comes to your water heater, if you are concerned about your power costs, you may want to keep the temperature no higher than 120 degrees Fahrenheit.
- Naturally, if money is not an issue, you may always raise the temperature to 140 degrees Fahrenheit on a regular basis.
- Once again, I strongly advise you to take into account the age and immunological health of your family members while determining the optimal water heater setting.
Water Appliances’ Energy-efficiency
The ″water preheat″ function on some dishwashers does not allow customers to adjust the temperature of the water heater’s thermostat setting to a more comfortable level. Those who own such a dishwasher are compelled to set the water heater to 140 degrees Fahrenheit as a matter of necessity.
- When it comes to the topic ″what temperature should a hot water heater be set at,″ you have two options. Turn down the temperature of your water heater to 120 degrees Fahrenheit if you want to save money on electricity or if you have elderly or young children in the house.
- If you have members of your household who are immunocompromised or if you don’t mind spending a huge power bill, set the water heater’s temperature to 140 degrees Fahrenheit or higher. If you have a dishwasher that does not have a preheat feature, you may additionally require this option.
Understanding the numerous elements that influence hot water temperature is essential to determining the optimal temperature.
What’s the Ideal Temperature for a Hot Water Heater?
- The level of comfort is a matter of personal taste.
- The temperature that one person considers cozy may be too warm or too cold for another person to be comfortable.
- That is why arguments over the thermostat at home or at the workplace are so prevalent.
- When it comes to the temperature of your water heater, the situation is a little more tricky to navigate.
- According to the United States Department of Energy, water heating accounts for around 18 percent of total energy use in a residence.
- That is a significant amount.
- Considering that every 10 degrees you lower the temperature of your hot water tank, you save 3-5 percent on your energy bill, it might be difficult to determine what temperature is the most comfortable for you while still being the most economical.
The recommended hot water temperature
- The Environmental Protection Agency provides us with a suitable starting point for setting our hot water tanks: 120 degrees.
- When the tank is not in use, this temperature is the bare minimum for killing off germs that might form in the tank.
- It can also help to avoid scorching, which is crucial in families with small children or older people.
- This setting should be able to provide adequate hot water for the average family while still being energy efficient.
When to adjust your water temperature
- The 120-degree setting is a good starting point for most people. There are a variety of variables or scenarios that may necessitate the use of a different temperature setting. Here are a few illustrations: If you or someone in your household has a weakened immune system or respiratory condition, turn your water heater up to 140 degrees Fahrenheit.
- With a bigger household, you may need to boost the temperature to ensure that there is enough hot water for everyone’s consumption
- To ensure that dishes are properly sterilized, if your dishwasher does not pre-heat the water (which is generally the case only with older models), turn on your water heater to 140 degrees.
How to change the temperature on your water heater
- If you have an electric hot water heater, you’ll need to remove the access panel and adjust the thermostat dial with a screwdriver after removing the access panel. Before performing any maintenance on your water heater, cut off the electricity to the device for your own safety. If you have a gas water heater, the temperature gauge does not contain numbers
- instead, it is labeled ″Hot″ and ″Warm,″ with a few lines between the two designations. The warm setting should be between 90 and 110 degrees Fahrenheit, and the hot setting should be between 140 and 150 degrees Fahrenheit. You’ll want to be somewhere in the middle of the range if you’re trying to set it at 120 degrees. Pour hot water into a glass and use a culinary thermometer to check the temperature. To get it exactly right, run hot water from the faucet for a few minutes, fill the glass, and test the temperature again. Continue to adjust the temperature until you achieve the desired result. It is critical for your household to have the appropriate amount of hot water. Saving money on energy expenditures is also important. Consult with a water heater professional from Reichelt Plumbing if you need assistance in one – or both – of those areas.

Best Temperature for a Water Heater
Post précédent Post suivant Post Many homeowners are curious about what the ideal temperature to set the water heater is. 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
- In order to save energy, the Department of EnergyLink opens in a new tab suggests that water heaters be set at 120 degrees Fahrenheit rather than at the typical setting of 140 degrees F. 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: Your dishwasher’s name is: If your dishwasher does not have a booster heater, you may want to maintain your water heater set at 140 degrees to provide the best cleaning results from your dishwasher. This function, on the other hand, may be found on the majority of current dishwashers. For further information, consult your owner’s handbook.
- Your physical and mental well-being: While the bacteria growth within a tank set at 120 degrees is acceptable for most people, if you have a compromised immune system, you should consider maintaining your tank at 140 degrees.
- The amount of persons that live in your residence is as follows: It is unlikely that you will run out of hot water if you maintain the tank at 120 degrees for an extended period of time if you live alone. If, on the other hand, six family members shower back-to-back each morning, the additional 20 degrees helps to guarantee that everyone has hot water.
- If you have children, you should consider the following: Scalding at the faucet is less likely to occur when your water heater is set to 120 degrees, which is especially significant if you have children or elderly family members living with you.
How to Adjust the Water Heater Temperature
- Perhaps you want to raise the temperature of the water heater to assist your dishwasher in doing its work more effectively, or you want to lower the temperature to reduce scalding. In any case, the following actions should be followed to alter the water heater setting: Take the following measurements to get the current temperature: Turn on the hot water at a faucet that is the furthest away from the water heater in order to obtain an accurate reading. 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 the following energy-saving modifications to your house. 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.
