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 Temperature Should a Hot Water Heater Be Set At?
There are six common problems that occur with your home’s water heater; what every homeowner should know about water heater maintenance; and six things you should know about water heaters.
Factors That Affect Hot Water Temperature Setting
These criteria are unaffected by the kind of piping you have (PEX, PVC, or copper), the method of heating the water (gas or electric), or even if you have a tankless hot water heater installed.
- Owners of dishwashers that do not pre-heat the water may wish to set their water heater temperature to 140 degrees
- Elderly or families with young children may want to keep the temperature at 120 degrees. BabyCenter.com states that “it takes just two seconds for a kid to acquire third-degree burns from water that is 150 degrees and five seconds if the water is 140 degrees, the temperatures at which hot water heaters frequently leave the manufacturer.” It is recommended that the hot water temperature be maintained at 140 degrees in homes with people who have a compromised immune system or respiratory problems. Because there is less demand for hot water and hence less money spent on hot water, many people who live alone prefer a lower temperature within an acceptable range. The temperature of the water tank is often set higher in big households, in order to support the increased demand for hot water
- Nevertheless, if you want to save money, every 10 degrees you lower the temperature of the water tank thermometer, you save 3 to 5 percent on your energy bill.
Are you still undecided? To begin, set the temperature to 120 degrees Fahrenheit and gradually raise it in small increments until you reach the desired shower temperature.
What’s Your Current Temperature Setting?
Check the temperature setting on the water heater (if one is available) or take a temperature reading from the faucet to determine what it is currently. After turning on the hot water faucet, allow it to run for a few minutes before getting the temperature reading.
Solutions to Common Hot Water Tank Problems
If you’re concerned about pathogens in your hot water, as well as the possibility of scalding water, you might consider installing a hot water tank booster. This allows you to maintain your water at 140 degrees in the tank while mixing it with cold water to bring the temperature down to 120 degrees before it reaches the faucet. Having a hot water circulating system installed in your home might alleviate the problem of waiting for hot water to reach the faucet in a large household. This method circulates hot water slowly through the pipes in order to prevent it from cooling down before it reaches the faucet.

Risks Of Too High Or Too Low Water Heater Temperature
You might be wondering what temperature to put your water heater to. When you purchase a water heater unit, the temperature is typically set by the manufacturer. However, this does not rule out the possibility of having some control over its temperature. The good news is that you may set the temperature to a level that is comfortable for you while yet ensuring the safety of your family. Previous to this, we wrote an article in which we spoke about how the heat in your shower might suddenly vary.
The temperature of the device is important since it can have an impact on how well it performs.
Top Risks of setting your unit temperature too high
An skilled plumber would advise against raising the temperature of your unit over the recommended level since it might endanger the safety of your children.
It can also have an impact on your utility costs and the heater itself. In order to assist you, we have listed the following risks:
1. Scalding Accidents

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.
To do this, set your thermostat to a steady temperature. This will help you keep control over the water temperature throughout your home, preventing it from being overly hot.

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:
- 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.

Setting your water heater’s temperature for best results
time required for reading: 2 minutes It’s possible that you don’t give your water heater much thought, but it actually plays a very crucial role in the plumbing of your home. In addition to higher power expenses, a malfunctioning water heater might result in water that is either scorching hot or ice cold. It is critical to plan annual maintenance to verify that your device is clean (hard water build-up can be detrimental to your water heater) and that the temperature range is within acceptable parameters.
- Setting the Water Heater to Its Optimal Performance Professionals recommend that you keep the temperature of your water heater between 130 and 140 degrees Fahrenheit at all times.
- While increasing the temperature over the suggested setting might result in burns, decreasing the temperature below the recommended level can also be hazardous.
- This might become a health danger for you and your family, putting you and your loved ones at risk of contracting diseases such as Legionnaires’ illness.
- Check the temperature of your water heater.
- The presence of sediment accumulation and calcification in the hot water tank itself will also be checked by a professional if the temperature on the water tank has been changed but you are still experiencing the same water temperature as you were before the temperature adjustment.
- After draining the tank, a professional can attempt to address the problem by scraping off any scale that may have built up over time and soaking the components in hot water.
- The average lifespan of a hot water heater is predicted to be between 8 and 12 years.
- Water heaters require regular maintenance.
- If you want to ensure that your water heater continues to function effectively, you may want to consider hiring a professional to perform this maintenance.
Maintaining your water heater’s temperature between the appropriate ranges is essential. This will prevent any bacteria from growing in the cold water and will protect you from being scalded by a shower that is much hotter than you anticipated.
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:
- 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 an excellent place to start. However, there are a few things to consider before lowering the temperature of your water heater a few degrees. If you set your water heater’s temperature too low, you risk turning it into a breeding ground for harmful germs. If you set it too high, you run the risk of causing a scorching mishap to yourself or another else. What is your lowest point? Short answer: 120 degrees Fahrenheit (or degrees Celsius). In most modern water heaters, this is the thermostat temperature that is pre-programmed, and it is the temperature that the United States Department of Energy recommends for optimal performance. At this temperature, dangerous microorganisms such as the kind that causes Legionnaires’ disease are stopped from proliferating and may even be eliminated completely. Because germs die off more quickly as the temperature rises, As a result, other organizations such as the Occupational Safety and Health Administration (OSHA) suggest that the water heater temperature be maintained at 140 degrees Fahrenheit or above. While 120 degrees should be deemed safe if everyone in your household has a healthy immune system, this temperature is also the bare minimum. Choosing a temperature that is closer to 140 degrees is safer, especially if anyone in the household has a weakened immune system. Additionally, if you have a dishwasher that does not create its own heat, you may need to raise the temperature setting. Scalding Is A Problem? After only five seconds in the presence of 140 degree water, a third-degree burn can occur. Furthermore, because it takes several seconds for hot water to travel through your pipes and reach your faucet or showerhead, you will never know when the scorching water will suddenly appear. Children may be more susceptible to water burns than adults due to the fact that their skin is thinner than that of adults, and the elderly may also be at greater risk due to impaired sensitivity, mobility, and response time. There is a remedy to the tug-of-war that exists between pathogenic safety and scalding safety: anti-scald valves are used. These may be installed at each point where hot water comes into contact with a person, allowing you to maintain your water heater set at 140 degrees while ensuring that the water never gets hotter than 120 degrees when it comes out of the faucet. In the hands of a skilled amateur plumber, installing an anti-scald valve is a simple task, although the level of difficulty varies depending on the plumbing system’s design. Whenever you have a difficult installation, call a licensed plumber for help. What, however, is the situation with regards to energy conservation? However, conserving energy and money are vital considerations, but they are secondary to protecting yourself and your family from potentially deadly infections. Having said that, it is feasible to reduce costs without utilizing the thermostat on your water heater.
As one of the most energy-intensive appliances in most houses, the water heater is an excellent place to start if you’re searching for ways to reduce your energy expenditures. However, there are a few things to consider before lowering the thermostat on your water heater a few degrees. Using a low water heater temperature might result in the creation of a breeding habitat for harmful germs. If you set it too high, you may be putting yourself at risk of a scorching mishap. How far are you willing to go?
- This is the temperature that is preset in most modern water heaters, and it is also the value that the United States Department of Energy recommends.
- Pathogens die off more quickly when the temperature rises.
- Even if everyone in your family has a robust immune system, 120 degrees should be regarded safe, but it should also be considered the absolute minimum temperature.
- If you have a dishwasher that doesn’t create its own heat, you may also need to raise the temperature setting.
- If the temperature is 140 degrees, water can produce a third-degree burn in as little as five seconds.
- In addition, because children’s skin is thinner than that of adults, the elderly may be more susceptible to water burns as a result of their lower sensitivity, movement, and response time.
- These may be installed at each point where hot water comes into contact with a person, allowing you to maintain your water heater set at 140 degrees while ensuring that the water never gets hotter than 120 degrees at the tap.
- If you have a complicated installation, it is best to see a certified plumber.
- It’s vital to save energy and money, but it’s not as important as protecting yourself and your family from potentially fatal infections.
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.
You probably don’t give your water heater much thought till you’re in the middle of a shower and the hot water stops working. It might be much more dangerous if the water is overly hot and causes scorching. Although you have the ability to modify the temperature of your water heater, should you? Even while you would believe that water heaters have a standard suggested temperature, this is not the case. Some water heater manufacturers factory-set their water heaters at 120°F (49°C), while others factory-set their water heaters at a default temperature of 140°F (60°C).
The Occupational Safety and Health Administration (OSHA) advises that the temperature be maintained at or above 122 degrees to assist avoid the formation of potentially dangerous microorganisms in the workplace.
Should I Change the Water Heater Temperature?
For the purpose of determining the most appropriate water heater temperature for your house, there are various elements to take into consideration.
Hot Water Kills Harmful Pathogens
A health problem arises when Legionella, the bacterium that causes Legionnaires’ disease, develops in the water systems of residential properties. According to the Occupational Safety and Health Administration, water heaters that are kept below 140 degrees and that include scale and silt may promote Legionella growth. Fortunately, the vast majority of healthy persons who are exposed to Legionella do not become ill. However, before you decide to turn up the temperature dial on your water heater, consider the following.
Hot Water Can Scald
The use of hot tap water is a leading cause of burn injuries and fatalities. Scald burns can be a serious threat in the house, especially if you have young children or elderly people living with you. Young children, because their skin is thinner, and the elderly, because their skin might be less sensitive to warmth and may be slower to respond to scalding water, are the two age categories that are most at risk for scalds. Adults may suffer third-degree burns if they are exposed to 150-degree water for even a brief period of time (as little as two seconds), according to the Consumer Product Safety Commission.
Though the temperature reaches 120 degrees, a five-minute exposure might result in third-degree burns even if the temperature is lower.
Minimize Risk with Anti-Scald Devices
The 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
- Avoid using your hot water for at least two hours before doing the test. If you have a tankless water heater, you can skip this step
- Otherwise, proceed as directed. Allow for a minimum of three minutes of running hot water. Make sure the temperature is correct by using a candy, meat, or water thermometer
- Set the temperature on your water heater’s thermostat to a more comfortable level. Continually repeat steps 2 and 3 until you get the required temperature. Wait for a full day to enable the water temperature to fluctuate before testing it once more. If you have a tankless water heater, you may skip this step.
Pro tip: Once you’ve found the temperature you desire, mark the location on the temperature dial of your water heater using a permanent marker.
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.
Home Warranty Coverage for Water Heaters
Your water heater’s “proper” temperature is actually 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 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.
Checking your water heater thermostat temperature

As an example, if someone in your home has a compromised immune system or chronic respiratory condition, a 140-degree setting is suggested in order to avoid Legionnaires’ disease and other water-borne health concerns from arising. In addition, if your dishwasher does not pre-heat the water, you may wish to keep the temperature at a higher setting for longer periods of time.
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:
- Each month, your home’s water heater consumes around 18 percent of its total energy consumption, ranking it as the second highest source of energy use. 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. You can determine whether or not you need to monitor the temperature of the unit by doing a simple test within your house. To use only hot water, turn on a faucet. Allow the water to heat up as much as possible before using it again. It is too hot to wash your hands or take a bath, isn’t it? Your water heater’s temperature may be set too high if you find yourself in this situation. The temperature of the water may be set too low if it never becomes warm. A Water Heater’s Optimum Operating Temperature Water heaters should be set at 120 degrees Fahrenheit, however depending on your home, this may not be the most efficient setting. A surprising amount of people are unaware that lowering the thermostat on their air conditioning unit too low can be just as harmful as setting it to a high range. Setting the water heater below 120 degrees Fahrenheit will ensure that cold showers are the least of your concerns. In the tank, germs will thrive if the temperature is kept too chilly. Legionella thrives in stagnant, chilly water, and it can produce a severe flu-like sickness if the water becomes stagnant and cool. When deciding whether or not to set your unit higher than 120 degrees, consider the amount of factors in your house. Thermal Factors in a Water Heating System The recommended 120-degree setting should be tried first. Following are some factors that may influence how high you should set your gauge if the water doesn’t heat up quickly enough:
If any of the following apply, putting the hot water heater between 120 and 140 degrees should be considered:
- A large family necessitates higher 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.

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:
- Warm = 80-90°
- Low = 80-90°
- Hot (or triangle symbol) = 120°
- A= 130°
- B= 140°
- C= 150°
- Very Hot = 160°
- High = 120°
There is a “Vacation” setting that appears from time to time. This does not heat the water, but it does ensure that the pilot light remains lit.
How to Set Temperature on an Electric Water Heater
Turn off the circuit breaker if necessary. Remove the access panels from the room. Under the insulation, look for the thermostat adjustment screwhole. Adjust the thermostat control to the appropriate temperature by using a straight screwdriver to make the adjustment. After replacing the insulation and panels, the power should be restored. Here’s a good video that demonstrates the procedure:
Factors That Affect Water Temperature
Some of the things that may influence the temperature of your hot water include the distance between the water heater and the outlet, the way the pipes are built, and the quality of the heating element itself, among others. Because of the length of the pipe and the small bore size, it will take longer for the hot water to reach the opening. Additionally, pipes that run beneath or outside the residence may be exposed to freezing or freezing temperatures in the winter and summer. Installing a hot water recirculation system in a large house may be worth considering since it can reduce the amount of time it takes to heat water in all of the property’s outlets while also resulting in significant cost savings over the long term.
If 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 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
It is recommended that your water heater be set within a specified temperature range for a variety of different reasons. A low temperature setting not only results in hot water that is merely lukewarm at best, but it can also promote bacterial development, which can lead to illnesses such as Legionnaires’ disease. This may be avoided by adjusting the temperature of the water heater to a level at which the bacteria Legionella cannot survive. A temperature of at least 140 degrees Fahrenheit (60 degrees Celsius) for water heaters is recommended by the Occupational Safety and Health Administration (OSHA) to prevent Legionella and other germs from growing in the water.
- The time it takes for third-degree burns to occur at 150 degrees Fahrenheit (66 degrees Celsius) is less than two seconds.
- Not to mention that a water heater that is set too hot might result in an excessively expensive power bill.
- The greater the distance between a faucet and the water heater, the greater the amount of heat that will be lost as the water flows, especially if the pipes are not insulated.
- When determining the appropriate temperature for your family and household, use your best judgment.
Make an adjustment, test it, and continue the process until you’ve found the ideal temperature setting for your house and water heater, which may take many attempts. Currently playing: Keep an eye out for this: Take a look inside the CNET Guide to Smart Living. 1:00
Adjusting water heater temperature
The interface used to control the temperature of a water heater will differ depending on the kind and model. Fortunately, the majority of water heater models can be modified in the same way. For example, most contemporary gas and electric water heaters are equipped with a thermostat concealed behind an insulated access panel. Electric water heaters are frequently equipped with two thermostats: one at the top of the tank and another at the bottom. Furthermore, most tankless water heaters include a display with a temperature reading as well as controls for altering the water heater’s temperature.
Turn on the water in the bathroom or kitchen sink and let it to run until the water is completely hot before using.
The process of adjusting a tankless water heater is quite similar to the process of adjusting your air conditioning thermostat. Adjust the temperature by using the digital control panel, which may be adjusted up or down as desired.
Gas or electric water heaters
Some gas water heaters include a dial towards the bottom of the device that may be adjusted simply by turning it – no tools are required for this operation. Nonetheless, most current tank water heaters (whether gas or electric) require a bit more effort, but the process is still straightforward and should only take a few minutes.
- Turning off the water heater’s electricity at the circuit breaker is the first step. To remove a thermostat(s), locate the access panel for the thermostat(s) and remove it using a screwdriver
- Remove the insulation by peeling it back. To adjust the thermostat, use a flathead screwdriver to turn it up or down.
- If your water heater has two thermostats, make sure they are both set to the same temperature. The temperature on the top thermostat should be a few degrees higher than on the bottom thermostat.
- Replace the insulation and re-install the access panel, if necessary. Reconnect the water heater’s power supply
- It is possible that you may need to relight the pilot light on a gas water heater.
Once you’ve made the necessary adjustments, you should wait at least three hours before checking the water temperature once more. It is possible that you may need to make more modifications in order to get the desired temperature. If you’ve increased the temperature and are still getting chilly showers, it’s possible that your hot water heater has to be serviced or completely replaced. Is the energy efficiency of your home high? Here are five different methods to find out. CNET’s Guide to Smart Livingis a one-stop shop for tips, techniques, and how-to guides that can help you live a more intelligent life.
What 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 experts agree that the ideal 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.

How to Set How Water Heater Temperature by Thermostat
You might be wondering how to adjust the temperature of your hot water heater. In this section, you will learn all you need to know about your gas or electric water heater thermostat, including how to adjust your hot water heater temperature thermostat and what temperature is optimum for hot water.
What’s the Right Temperature for a Hot Water Heater?
It’s an often asked question: what is the optimal temperature for hot water? Setting a tank-based hot water heater to 120 degrees Fahrenheit is recommended by the United States Department of Energy. If you have never changed the temperature of your hot water heater, it is most likely set to the 140-degree Fahrenheit level that is recommended by most manufacturers of hot water heaters. What is the significance of adhering to this temperature standard? If the temperature setting on the water heater thermostat is set too high, the water will be excessively hot and might cause burning or scorching.
How to Set Your Hot Water Heater Temperature Thermostat Setting
Before you make any modifications to your hot water heater temperature thermostat setting, ascertain what your present temperature is set at so you’ll know how much you need to alter the settings. You may use any normal kitchen thermometer to determine the temperature easily. You should calibrate your thermometer after you have determined the current temperature setting. To do so, place your thermometer in a cup of icy water until the temperature dial descends to 32 degrees, or the lowest degree on your thermometer’s gage.
While you calibrate your thermometer, pick the faucet positioned closest to the water heater and run it until it’s hot.
Precautions must be taken! If your temperature is set too high, it may be hot enough to burn you. Once the water is hot, fill a cup halfway with it and take the temperature with a thermometer by inserting it in the water.
Adjusting aGasHot Water Heater Temperature Thermostat Setting
Before you make any modifications to the temperature thermostat setting on your hot water heater, you should first ascertain what the current temperature is set at so that you can establish how much you need to alter the settings. A conventional cooking thermometer may be used to quickly and accurately detect the temperature. You should calibrate your thermometer after determining the current temperature setting. Fill a cup halfway with cold water and submerge your thermometer until the temperature dial reaches 32 degrees, or the lowest temperature displayed on your thermometer’s gauge, and then remove it.
Meanwhile, locate the faucet that is closest to the water heater and turn it on until it is hot (while you are calibrating your thermometer).
If your thermostat is set too high, the temperature may be high enough to burn you.
- Identify the present temperature setting of your hot water heater thermostat before making any alterations to the thermostat settings. This will allow you to estimate how much temperature adjustment is required. To simply determine the temperature, you may use any basic cooking thermometer. You should calibrate your thermometer once you’ve determined the current temperature setting. Fill a cup halfway with cold water and submerge your thermometer until the temperature dial reaches 32 degrees, or the lowest temperature displayed on your thermometer’s gauge, then repeat the process. Calibration of the thermometer is simply a reset, which ensures that you will receive correct temperature readings in the future. Meanwhile, locate the faucet that is nearest to the water heater and turn it on until it is hot (this will take a few minutes). Take precautions! In some cases, turning up the temperature too high might result in burns. Once the water is hot, fill a cup halfway with it and take the temperature by submerging your thermometer in it.
Adjusting anElectricHot Water Heater Temperature Thermostat Setting
The process of adjusting the temperature thermostat setting on an electric hot water heater is a little more difficult, but still pretty simple. The vast majority of electric water heaters are equipped with two thermostats: an upper and a lower thermostat, both of which are placed beneath two control panels. To ensure your electric water heater operates as effectively as possible, you should set both of the thermostats at the same temperature. One thing to keep in mind is that some tiny electric hot water heaters only have one thermostat.
Here’s how to adjust the temperature on your electric hot water heater thermostat:
Please keep in mind that you will want a screwdriver to execute the following procedures in order to alter the temperature of your water heater.
- Make sure your water heater is off by turning off the electricity. This may be accomplished by locating your circuit breaker and shutting off the electricity in the area surrounding your water heater
- Then, locate the thermostat(s) on your water heater and turn them on. Typically, they are located behind a control panel that is secured with screws. Remove the cover from the access panel using your screwdriver (s). To access the thermostat, you may need to remove the insulation from your heater if it is properly insulated. The thermostats will be controlled by a dial, and the dials will have a varying reading depending on the manufacturer of the heater. Once the control panel has been removed, you may change the temperature knobs to make the room hotter or colder according on your preferences in terms of temperature. Take care to set both thermostats to the same temperature setting if you have more than one. Replace the control panel covers and the screws with your screwdriver after they have been removed. After that, re-energize your water heater’s electrical system. After many hours, check the temperature of your hot water (about three to four). Continue to follow the above instructions until the water temperature reaches the required setting
- If it still does not, repeat them until the temperature reaches the ideal setting for your needs.
Other Considerations: Water Heater Thermostat Setting Safety
There is one thing you should be aware of: your water heater is fitted with something known as a temperature and pressure relief valve, abbreviated “T P valve.” These can become worn out over time, and one sign that they should be replaced is the presence of water leaking through. This is a very crucial safety feature. If your unit is old, or if your hot water heater pressure relief valve is leaking after it has been replaced, get it examined by a competent plumbing professional.
