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?

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 factors are unaffected by the type of plumbing you have (PEX, PVC, or copper), the method of heating the water (gas or electric), or even whether 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?

Continue to be on the fence? Make a start with a temperature of 120 degrees and gradually raise it in small increments until you reach the desired temperature.

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

Alternatively, you will not want your unit’s temperature to be set too low, since this can result in condensation. A health problem might result if you do so.

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.

Your installer can help you adjust your water heater temperature.

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.

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.

  1. 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.
  2. While increasing the temperature over the suggested setting might result in burns, decreasing the temperature below the recommended level can also be hazardous.
  3. 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.
  4. Check the temperature of your water heater.
  5. 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.
  6. 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.
  7. The average lifespan of a hot water heater is predicted to be between 8 and 12 years.
  8. Water heaters require regular maintenance.
  9. 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.

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.

Family Handyman

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

Adjusting your home heating system’s thermostat settings is probably one of the first things that comes to mind when thinking about ways to save energy in your own house. The thermostat on your water heating system, on the other hand. Water heaters marketed now come pre-programmed at a temperature of 140 degrees or more, which is hot enough to induce scorching but too high for most people to use (there are exceptions to this, however, as we will see). As recommended by the Department of Energy, a 120°F water heater thermostat setting is more than enough to minimize mineral development and corrosion in your water heater and pipes while also keeping your water supply safe to drink.

If you lower your water heater’s thermostat setting by 20 degrees, you’ll save money in two ways: first, you’ll reduce standby losses (heat lost from the water heater’s storage tank when it’s left in a cold basement), and second, you’ll reduce fuel consumption (because you won’t need to raise the temperature as high, you’ll use less gas or heating oil to heat it up).

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.

  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.
  3. 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.
  4. A tank that is kept at a too-cold temperature can encourage the growth of germs.
  5. The amount of elements in your home will influence whether or not you should set your unit to a temperature greater than 120°.

The Influence of Water Heater Temperature Factors Check out the recommended 120-degree setting. Depending on whether or not the water heats up sufficiently, the following factors may influence how high you should set your gauge:

  • Whether the device is fueled by electricity or gas
  • The type of pipe material used in your residence (PEX, copper, or plastic)
  • Whether the hot water unit is equipped with a typical tank or is tankless

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.

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 travels, 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.
  • The thermostats on your water heater should be adjusted by the same amount if your water heater has two of them. There should be a slight difference in temperature between the top and the bottom thermostats.

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’s the Best Temperature for 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.

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.

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.

What Temperature Should I Set My Water Heater?

Water heaters are a critically vital component of your house, but most homeowners don’t give them much thought once they’ve been installed in the first place. Unfortunately, installations completed before you moved in or by specialists who don’t take the time to ensure that the unit is running properly might result in incorrect water heater temperatures being reached. On the one hand, scorching hot water can be dangerous, while on the other, water that does not stay hot long enough to hinder the growth of hazardous germs can be quite dangerous.

Consider the following questions for yourself:

  • Is it possible that the base temperature of the water heater has altered after it was initially installed? Water heaters used to be manufactured at a temperature of 140°F, which may induce scorching in as little as 5 seconds. Some heaters are set at a temperature of 160°F, which is far too high. A fraction of a second at that temperature will result in third-degree burns. Water heaters are now factory-set at 122.5°F, which is a much safer setting
  • If the temperature has been adjusted, it is possible that the temperature has been set too low. A water temperature that is set too low is no more beneficial than a temperature that is set too high. Low temperatures, between 90 and 115 degrees Fahrenheit, might foster the growth of germs that can make you or your family very sick. It is necessary to prevent temperatures that are too low.

So What is the Best Water Heater Temperature Setting?

The majority of specialists think that the best temperature range for personal comfort and safety is 120°F to 125°F. Using this setting, you can prevent bacterial development while not having to worry about possible damage from being caused by hot temperatures. An additional benefit of decreasing the temperature is that you will save money on your energy costs. It’s also a good idea to spend some time getting acquainted with your water heater, which is often disregarded but is a vital component of your home’s plumbing system.

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. Insert your cooking thermometer and make any necessary adjustments to the temperature settings.

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.

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 setting the thermostat does not result in the desired temperature, it is possible that the water heater element has to be replaced. 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 I Set for My Water Heater?

adminon posted a new comment 5:33:44 a.m. on May 25, 2017 It is possible to set a maximum temperature on your home’s water heater, which governs how hot the water coming out of your faucets may be at any one moment. While most of us don’t consider this to be a modifiable setting, it is in fact something that you can modify if you so want. A new water heater is usually set to a maximum temperature of 140 degrees Fahrenheit when it is first installed. Some believe that is the optimal temperature, while others believe that it is preferable to lower the maximum temperature to 120 degrees.

Here is a deeper look at what they are:

The argument for 120 degrees

As recommended by the United States Department of Energy and the American Society of Sanitary Engineering, the best temperature to set for a hot water heater should be 120 degrees Fahrenheit. The following are some advantages:

  • It is more beneficial to the environment. Not only does it need electrical or gas energy to heat your water, but it also takes energy to keep the water in the storage tank at that temperature (so you have hot water on demand). By lowering the temperature by 20 degrees, you may dramatically reduce the amount of energy consumed, resulting in significant savings. The energy savings are beneficial not just to the environment, but also to your money, with the potential to save you up to $60 per year. It also helps to avoid mineral accumulation. Using cooler water means that minerals are less likely to be deposited in your pipes, reducing the troubles caused by hard water and keeping your water flow unimpeded
  • It also helps to prevent severe scalding. This is, without a doubt, the most compelling of the arguments. Water that is 140 degrees as it comes out of the faucet can cause significant burns in as little as two or three seconds. When exposed to 120 degree water, on the other hand, it takes only a minute or two for the skin to begin to burn. The skin of young children and the elderly is more vulnerable to burns than that of other individuals, and scorching can be fatal for them.

The argument for 140 degrees

Why would anybody propose cooking at a higher temperature when there is a danger of scalding? Actually, another federal organization, the Occupational Safety and Health Administration, or OSHA, has determined that 140 degrees is a safer temperature to work at. The most pressing worry is the elimination of a certain strain of bacteria from the environment. The majority of homes will not have to be concerned about this because water heated to 120 degrees will kill the vast majority of common germs.

Older water systems with rusted pipes, as well as a water storage system that enables water to stagnate outdoors or for extended periods of time, are all potential risk factors for LDB bacteria growth.

Which should you choose?

The majority of houses can safely reduce the thermostat to 120 degrees Fahrenheit. If you live with children or elderly relatives, the risk of scalding is far greater than the risk of contracting a rare type of germs. When your water supply has been alerted that it is susceptible to LDB bacteria, or if you have an older system with stagnant water, you should raise the temperature of your water. If you have a delicate or weakened immune system, it’s particularly crucial to keep your body temperature higher than normal.

You may also consider purchasing a tankless water heater, which warms water only when it is required and does not require a storage tank.

If you choose any temperature setting, you will save money!

Changing the temperature on your water heater

Once you’ve determined which temperature is best for your home, you’ll need to figure out how to make the adjustment. To begin, ascertain the temperature at which your water is now running. This step is as simple as allowing the hot water from your faucet to run for a few minutes, filling a glass, and using a kitchen thermometer to check the temperature of the water. If you decide that you need to modify the temperature, you may need to reference the owner’s handbook for your water heater to see where the temperature setting is located.
