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. 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. 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.

  1. 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.
  2. Do you have an appliance that is energy efficient?
  3. 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.
  4. 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.
  5. How many people do you have living in your house?
  6. Those who like a hotter shower increase the ratio of hot to cold water in their shower.
  7. The temperature of the water that comes out of your water heater, on the other hand, will have an impact on this as well.
  8. People that use cooler water heaters will require more hot water and less cold water in order to achieve their goals.
  9. 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!

  1. Many hot water heaters are equipped with a temperature control dial.
  2. Start with 120°F and gradually increase the temperature in small increments until you get your desired result.
  3. 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.
  4. 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).
  5. 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.

Are you still undecided? To begin, set the temperature to 120 degrees Fahrenheit and gradually raise it in small increments until you reach the desired shower temperature.

What’s Your Current Temperature Setting?

Check the temperature setting on the water heater (if one is available) or take a temperature reading from the faucet to determine what it is currently. After turning on the hot water faucet, allow it to run for a few minutes before getting the temperature reading.

Solutions to Common Hot Water Tank Problems

If you’re concerned about pathogens in your hot water, as well as the possibility of scalding water, you might consider installing a hot water tank booster. This allows you to maintain your water at 140 degrees in the tank while mixing it with cold water to bring the temperature down to 120 degrees before it reaches the faucet. Having a hot water circulating system installed in your home might alleviate the problem of waiting for hot water to reach the faucet in a large household. This method circulates hot water slowly through the pipes in order to prevent it from cooling down before it reaches the faucet.

Risks Of Too High Or Too Low Water Heater Temperature

You might be wondering what temperature to put your water heater to. When you purchase a water heater unit, the temperature is typically set by the manufacturer. However, this does not rule out the possibility of having some control over its temperature. The good news is that you may set the temperature to a level that is comfortable for you while yet ensuring the safety of your family. Previous to this, we wrote an article in which we spoke about how the heat in your shower might suddenly vary.

The temperature of the device is important since it can have an impact on how well it performs.

Top Risks of setting your unit temperature too high

An skilled plumber would advise against raising the temperature of your unit over the recommended level since it might endanger the safety of your children. It can also have an impact on your utility costs and the heater itself. In order to assist you, we have listed the following risks:

1. Scalding Accidents

Setting the temperature too high might result in scorching mishaps that result in burn injuries. According to the findings of a study on water heater temperature and attributes, many water heaters are frequently set at dangerously high temperatures. Several studies by the Centers for Disease Control and Prevention (CDC) have discovered that scald burns are the most common cause of injury in younger children. Every day, over 300 children between the ages of 0 and 19 are treated in emergency departments for burn-related injuries, with two of these children dying as a result of their injuries.

In order to avoid tap burns, experts strongly recommend that you have your water heater inspected. Accidents such as this may be prevented by allowing your water to flow for three minutes and then monitoring the temperature with a candy thermometer thereafter.

2. High electricity bill

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.

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.

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.

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.

  1. The quick answer is: 120 degrees Fahrenheit (degrees Celsius).
  2. At this temperature, dangerous microorganisms such as the kind that causes Legionnaires’ disease are stopped from proliferating and may even be eliminated entirely.
  3. 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.
  4. Choosing a temperature closer to 140 degrees Fahrenheit is preferable, especially if anyone in the household has a weakened immune system.
  5. What Is the Deal with Scalding?
  6. 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.
  7. There is a remedy to the tug-of-war that exists between pathogenic safety and scalding safety: anti-scald valves are available.
  8. 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.
  9. 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.

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.

  1. 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
  2. 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.

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.

What Temperature Should a Hot Water Heater be Set At?

What temperature should a hot water heater be set to in order to provide hot water? Despite the fact that you may not think about your water heater very often, it is an important component of your home’s plumbing system. It is possible that a faulty water heater will result in increased electricity bills as well as water that is either blazing hot or freezing cold. It is vital to schedule annual maintenance in order to ensure that your unit is clean (hard water build-up is detrimental to your water heater) and that the temperature is set appropriately on the thermostat.

Manufacturers and the Department of Energy hold diametrically opposed perspectives.

The majority of experts feel that any temperature below 120 degrees Fahrenheit increases the likelihood of bacteria, such as legionella, which causes Legionnaire’s disease, developing within your water heater as a result of stagnant water in your water heater.

Optimal Water Heater Temperature

It is important to remember that the kind of pipe, how the water is heated (gas or electric), and whether your system is a tank or tankless all have no effect on the temperature. A variety of variables must be taken into account when determining an appropriate temperature, including:

  • Keep the temperature at 120°F if you have little children and/or the elderly in your home, who are susceptible to third-degree burns in seconds, or if you live alone, because you will have less need for hot water. 140 degrees Fahrenheit should be considered if your home contains an immunocompromised individual, a dishwasher that does not pre-heat, or a large number of people due to a greater need for hot water.

The question is, what is the cost of energy? We recognize your frustration! On average, water heaters account for 14-18 percent of a home’s total energy use. Furthermore, it may be tempting to turn the thermostat down in order to save money on energy costs. It’s worth mentioning that reducing the temperature by 10°F results in a 3-5 percent reduction in energy use. Legionella, on the other hand, is capable of surviving at temperatures as high as 122 degrees Fahrenheit. So make sure to strike a balance between your risk tolerance and your energy consumption targets!

  • A temperature dial is a feature that is typically found on water heaters.
  • Start with 120°F and progressively raise the temperature until it is to your satisfaction.
  • The installation of a water tank booster may be an appropriate option in families where the necessity to maintain a higher hot water temperature for health safety must be balanced against the danger of scorching.
  • Instead, you can live in a place where hot water takes a long time to reach the faucet, no matter what degree you set it at (or a certain tap farthest from the hot water heater).
  • No matter which option you pick, we are merely a phone call away if you are suffering hot water problems!

Check the Temperature of Your Water Heater

When you are concerned that the temperature of your water heater is incorrectly set, call a plumber who will be able to quickly and simply verify the setting with a specific thermometer and make the necessary adjustments to your water heater. The presence of sediment build-up and calcification within the hot water tank may be determined by an experienced technician after you have attempted to modify the temperature of your water tank but have not seen any variation in temperature. If you hear sizzling or hissing noises in the tank, this is another indicator that sediment has accumulated in the tank.

Water Heater Life Expectancy

The bulk of hot water heaters are expected to last between 8 and 12 years, according to predictions.

The replacement of your water heater should be your first choice if your unit is 10 years old or older and seems to be leaking or not performing correctly. Repairing your water heater may only provide a temporary solution to your problem.

Water Heater Maintenance

As with any piece of equipment, a little care and maintenance may go a long way toward extending the life of your water heater and keeping it in good working order. If you want to ensure that your water heater is in good working condition, you should consider contacting a professional to do the necessary maintenance. Always double-check that the temperature of your hot water heater is adjusted to the suitable levels. This will prevent any bacteria from growing in the cold water and will protect you from being scalded by a shower that is much hotter than you anticipated.

What temperature is right for your water here?

When it comes to conserving energy at home, one of the first things that comes to mind is most likely changing the thermostat settings on your home heating system to the lowest possible level. Nevertheless, what about the temperature control device on your water heating system? The factory default setting on most water heaters supplied today is 140 degrees, and sometimes even higher – a temperature that is high enough to induce scorching but not high enough to meet the needs of most people (there are exceptions to this, however, as we will see).

However, the most compelling reason to lower your water temperature is to save electricity (and, consequently, money).

When you adjust your water heater’s thermostat to 120 degrees Fahrenheit rather than 140 degrees Fahrenheit, you’ll save around $50 per year in standing heat loss and more than $400 per year in fuel use.

A 140° setting is right in certain circumstances

However, while the majority of individuals can get by with a 120-degree setting, there are some situations in which a 140-degree setting is more appropriate. For example, if you have a member of your family who has a compromised immune system or chronic respiratory condition, a 140-degree setting is suggested to avoid Legionnaires’ disease and other water-borne illnesses.

Additionally, if your dishwasher does not pre-heat the water, you may want to keep the temperature at a higher setting.

Best Temperature for a 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:

  • Water heater temperature: If your dishwasher does not have a booster heater, you may wish to keep your water heater temperature at 140 degrees to get the best cleaning possible. This function, on the other hand, may be found on the majority of current dishwashers. For further information, consult your owner’s handbook. Your physical and mental well-being: While the bacteria growth within a tank set at 120 degrees is acceptable for most people, if you have a compromised immune system, you should consider maintaining your tank at 140 degrees. The amount of persons that live in your residence is as follows: It is unlikely that you will run out of hot water if you maintain the tank at 120 degrees for an extended period of time if you live alone. If, on the other hand, six family members shower back-to-back each morning, the additional 20 degrees helps to guarantee that everyone has hot water. If you have children, you should consider the following: Scalding at the faucet is less likely to occur when your water heater is set to 120 degrees, which is especially significant if you have children or elderly family members living with you.

How to Adjust the Water Heater Temperature

Perhaps you want to raise the temperature of the water heater to assist your dishwasher in doing its work more effectively, or you want to lower the temperature to reduce scalding. In any case, the following actions should be followed to alter the water heater setting:

  • Obtain an accurate reading of the present temperature by turning on hot water at a faucet that is the furthest away from the water heater, as shown in the diagram. Place a thermostat under flowing water to see whether or not an adjustment is required
  • Locate the thermostat dial by turning it clockwise: Gas water heater tanks include dials towards the bottom of the tank that regulate the temperature of the water. Water heaters that run on electricity frequently have their thermostats tucked away beneath screw-on panels. If your electric water heater contains upper and lower heating components, there may be two dials on the control panel. Take the following measurements and make the necessary adjustments: Increase or decrease the temperature setting on the thermostat by a little amount from its beginning level. Then you’ll have to wait a few of hours. Measure the water temperature once more and make any additional modifications that are necessary. Whenever you’re through, make a note of the final temperature on the dial so that you may quickly adjust it in the future.

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.

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.

  1. The time it takes for third-degree burns to occur at 150 degrees Fahrenheit (66 degrees Celsius) is less than two seconds.
  2. Not to mention that a water heater that is set too hot might result in an excessively expensive power bill.
  3. 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.
  4. When determining the appropriate temperature for your family and household, use your best judgment.
  5. Make an adjustment, test it, and continue the process until you’ve found the ideal temperature setting for your house and water heater, which may take many attempts.

Adjusting water heater temperature

The interface used to control the temperature of a water heater will differ depending on the kind and model. Fortunately, the majority of water heater models can be modified in the same way. For example, most contemporary gas and electric water heaters are equipped with a thermostat concealed behind an insulated access panel. Electric water heaters are frequently equipped with two thermostats: one at the top of the tank and another at the bottom. Furthermore, most tankless water heaters include a display with a temperature reading as well as controls for altering the water heater’s temperature.

Turn on the water in the bathroom or kitchen sink and let it to run until the water is completely hot before using. Then, to get an accurate reading, place a thermometer beneath the surface of the water.

Tankless

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.
