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.

  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 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.

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. In this article, we will discuss the dangers of setting your water heater’s temperature too high or too low, as well as the optimal temperature for it to perform properly.

Top Risks of setting your unit temperature too high

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

1. Scalding Accidents

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

Accidents such as this may be prevented by allowing your water to flow for three minutes and then monitoring the temperature with a candy thermometer thereafter.

2. High electricity bill

Warning: Using a water heater with the temperature set too high will cause your energy cost to rise! According to the Department of Energy, standby heat losses from your water heater can cost you anywhere from $36 to $61 per year in energy savings. The good news is that by lowering your thermostat, you may save anywhere from 4 percent to 22 percent on your annual energy expenditure. Lowering the temperature of your water heater can help to decrease standby heat loss, which is one of the reasons you have a high energy cost.

3. Lowers your unit’s service life

According to some sources, hot water can accelerate the accumulation of hard water mineral silt, particularly calcium carbonate, in the tank’s interior. It is possible that the buildup would cause corrosion in the water heater tank, which will result in a reduction in the estimated lifespan of the complete device. Leaks and polluted water might occur as a result of the rust accumulation in the storage tank. Another major reason for water heater failure is the deposit of rust on the interior of the heater.

We wrote an essay about why it’s important and how you can extend its lifespan.

Risk of setting your unit temperature too low

If you want to save money on energy costs, you should avoid setting the temperature of your unit too low. It is possible that you will have a health problem as a result.

1. Legionnaires disease

Every year, around 100 people in the United States are sent to hospitals due to a form of bacterial illness that can be caused by water heaters. The infections connected with the bacterium were responsible for up to 12 percent of the country’s death rates. Specifically, the Legionella bacteria are responsible for this particular kind of atypical pneumonia. It is common to find this bacterium in water at low temperatures — often between 20 and 45 degrees Celsius. You can contract the disease if you inhale small water droplets in the air that contain germs that cause it.

Evidence indicates that the majority of the bacteria’s spread occurred through the provision of drinking water in private residences.

It has been shown that the danger of contamination is significantly reduced when water heaters are set at 60°C or 140°F.

Ideal Temperature For Your Water Heater

The optimum temperature is. What several agencies have to say about the optimal temperature is summarized below: According to the Occupational Safety and Health Administration (OSHA) and the World Health Organization (WHO), water heaters kept below 60 degrees Celsius (140 degrees Fahrenheit) may promote Legionella development. This temperature, on the other hand, will almost certainly increase the likelihood of being burned by searing hot water. If you have young children at home, the Centers for Disease Control and Prevention (CDC) and the Energy Department recommend that you set your water heater’s thermostat to 120°F or lower.

This will help you keep control over the water temperature throughout your home, preventing it from being overly hot.

So, is it 120°F or 140°F?

We recommend keeping the temperature between 120 and 140 degrees Fahrenheit. However, you may regulate the temperature of your water heater between 130 and 140 degrees Fahrenheit, which is very useful for large water heaters used in hospitals and industrial settings. In case you have little children at home, set the temperature to 120°F, which is considered safe by the majority of the population.

Your installer can help you adjust your water heater temperature.

As part of our service, our qualified specialist at SPS Plumber can assist you with setting the temperature of your water heater to the proper setting. In addition, we can do annual water heater maintenance on your unit. To schedule an appointment, please call us at 408-622-8183 (South Bay Area) or 209-597-9107 (Central Valley) right away!

  8. To ensure that your water heater is functioning correctly, you may want to consider hiring a professional to complete this maintenance.

Keep your water heater’s temperature between the appropriate ranges at all times. Using this method will prevent germs from growing in the cold water and will protect you from being scalded by a shower that is far hotter than you anticipated.

Determine the Best Temperature for Your Water Heater

The usual setting for most water heaters is 140 degrees Fahrenheit, but the Department of EnergyLink opens in a new tabrecommends lowering the temperature to 120 degrees Fahrenheit in order to conserve energy. To summarize, you shouldn’t drop the temperature of your tank below 120 degrees because doing so encourages bacteria development (unless you are traveling out of town, in which case the DOE suggests lowering the temperature to its lowest level). Consider the following factors that influence the temperature at which you should set your water heater:

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

How to Adjust the Water Heater Temperature

Water heater at 140 degrees: If your dishwasher does not have a booster heater, you may want to maintain your water heater at 140 degrees to ensure that it cleans the most effectively. Modern dishwashers, on the other hand, are equipped with this capability by default. For further information, consult your owner’s handbook. In terms of your physical well-being, While bacteria growth in a tank at 120 degrees is generally considered safe for most individuals, those with a compromised immune system might consider maintaining their tank at 140 degrees.

The extra 20 degrees, on the other hand, can assist ensure that everyone has hot water when six family members shower back-to-back each morning.

This is especially significant if you have children or elderly people living with you.

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

Other Ways to Improve Water Heater Efficiency

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 illustration. To determine whether or not an adjustment is required, run a thermostat under running water. Find the thermostat dial by doing the following: In the bottom of gas water heater tanks, there are dials for adjusting the temperature. Thermostats in electric water heaters are frequently hidden under screw-on covers. If your electric water heater contains upper and lower heating components, there may be two dials on the control panel to choose from.

And then let it a couple of hours to work its magic.

Whenever you’re through, make a note of the final temperature on the dial so that you may simply adjust it in the future;

  • Insulate the water heater tank to decrease heat loss during standby mode. Renovate your bathroom by replacing your showerheads and faucets with low-flow models that use less hot water. Replace your existing water heater with a tankless one that warms water on demand, eliminating the need for storage and the accompanying standby heat loss.

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.

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. 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 Is The BEST Water Heater Temperature Setting?

Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. If you have already set the temperature and are thinking to yourself, “I don’t have any hot water,” or “I don’t have enough hot water,” there are a few variables that might be causing the problem. If all else fails, it’s possible that the heating element is faulty and has to be replaced.

How To Check Your Water Heater Temperature

The majority of water heaters do not have a temperature gauge with a digital readout on them. Temperatures or heating ranges are marked on thethermostat, rather than numbers. A cup and a culinary thermometer will be required in order to correctly determine the temperature of the hot water heater. If you haven’t used your water heater in at least one hour, turn on the faucet that is nearest to it. Allow the water to run for at least one minute to ensure that the water is at its warmest possible temperature before filling the cup with it.

Recommended Temperature Settings

Water heaters are pre-programmed to operate at OSHA-recommended temperatures, which are around 140 degrees. The Environmental Protection Agency, on the other hand, recommends lowering the thermostat down to 120 degrees Fahrenheit to save power use and using a booster heater to attain sanitizing temperatures at certain outlets. Another point of view is that lower temperatures are preferable for homes with little children, although higher temperatures are more effective in cleaning and sanitizing surfaces.

Recommendation from me Water heaters should be adjusted to 130 degrees Fahrenheit, in my opinion, in practically all circumstances. However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.

How To Turn Up Your Water Heater

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’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.

Family Handyman

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.

  1. Is it too hot for you to wash your hands or take a bath?
  2. If the water never becomes warm, it is possible that the temperature is set too low.

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 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 once you have 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, 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).

Precautions must be taken! If your thermostat is set too high, the temperature may be high 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 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. Setting both thermostats to the same temperature can help to guarantee that your electric water heater operates as effectively as possible. 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.

  1. 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
  2. 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
  3. If it still does not, repeat them until the temperature reaches the ideal setting for your needs.

Hot Water Can Scald

The use of hot tap water is a leading cause of burn injuries and fatalities. Scald burns can be a serious threat in the house, especially if you have young children or elderly people living with you. Young children, because their skin is thinner, and the elderly, because their skin might be less sensitive to warmth and may be slower to respond to scalding water, are the two age categories that are most at risk for scalds. Adults may suffer third-degree burns if they are exposed to 150-degree water for even a brief period of time (as little as two seconds), according to the Consumer Product Safety Commission.

In addition, burns can develop after a six-second exposure to 140-degree water or a 30-second exposure to 130-degree water. Though the temperature reaches 120 degrees, a five-minute exposure might result in third-degree burns even if the temperature is lower.
