What Setting Should My Hot Water Heater Be On?

What Temperature Should a Hot Water Heater Be Set at?

  1. How many of you are aware of the fact that the common hot water heater temperature setting is typically 140 degrees Fahrenheit?
  2. In most cases, water heater manufacturers specify this value as the default value.
  3. This temperature level will aid in the prevention of the spread of Legionella bacteria in your household water supply.
  • The question is, at what temperature should a hot water heater be set?
  • Temperatures between 120 and 140 degrees Fahrenheit are recommended for your heater, since these temperatures will eliminate bacteria in your water, according to professionals.
  • Furthermore, the optimal water heater temperature is determined by a variety of parameters, which I will address in greater detail later in this post.

Hot Water Temperature Levels Recommended by Professionals

  1. What temperature should you set your water heater to?
  2. A minimum water temperature of 140 degrees Fahrenheit is required for larger residential systems, according to the Occupational Safety and Health Administration (OSHA).
  3. Smaller systems, on the other hand, require temperatures of at least 130 degrees Fahrenheit.
  • This setting will produce 120 degrees Fahrenheit faucet or tap water temperature, which is the appropriate temperature for home hot water.
  • The Centers for Disease Control and Prevention (CDC) and the United States Environmental Protection Agency (EPA) have determined that 120 degrees is the maximum acceptable hot water temperature (EPA).
  • A hot water temperature of 120 degrees Fahrenheit is sufficient to keep infections at bay while also allowing for long, steamy showers to be enjoyed.
  • It will also have a positive impact on total energy and power usage.

The CPSC (Consumer Product Safety Commission) recommends that customers set their water heater’s thermostat to 120 degrees Fahrenheit to avoid scorching, even though the maximum temperature for most water heaters is 150 degrees Fahrenheit.The skin of youngsters and the elderly is more sensitive to burns when exposed to hot water because their skin is thinner and burns more quickly.Furthermore, after two seconds of exposure to 150-degree hot water, the majority of children will suffer from a 3rd-degree burn.At 131 degrees Fahrenheit, a kid can be scalded in less than 4 seconds if the temperature is maintained.Consequently, children should constantly be monitored to avoid unintentional water burns caused by playing with the faucet temperature settings when they are young.The majority of scalding burns in children occur as a result of an accident, which is why parents are inclined to lower the temperature of the water heater.

Anything lower than 120°F, on the other hand, will not provide you with an additional layer of protection against the potential multiplication of Legionella and other bacteria in your drinking water.Although you have the ability to customize the temperature of your water heater to your liking, it is critical to be conscious of your water heater consumption habits in order to safeguard your family from the harmful consequences of improper temperature management.

Factors That Affect Hot Water Heater Setting

There are a variety of things that influence how we set the temperature of our water heating system. The following factors will assist you in determining the optimal heat level:

1. Households With Elderly People and Children

  1. As previously stated, older adults and children have thinner skin than younger children and are therefore at greater risk of scalding.
  2. According to reports, children as young as 4 years old are admitted to hospitals with burn-related ailments, including scald burns and contact burns.
  3. In the meanwhile, reports of old or vulnerable persons suffering from burn injuries or infections are extremely rare in the media.
  • However, as a precautionary measure, we must continue to monitor that the water heater’s temperature does not exceed 120 degrees Fahrenheit.
  • Although there is one exception to this rule, it is worth mentioning.
  • For those who have an immunocompromised member of the family, it is recommended that you adjust your unit’s temperature to 140 degrees Fahrenheit, as recommended by the Department Of Energy.

2. Household Size

  1. If you live alone, you might expect to have a lower water use.
  2. As a result, the vast majority of single inhabitants would most likely adopt a lower temperature to preserve energy.
  3. Lowering the temperature of the water heater to 120 degrees Fahrenheit might help you save up to ten percent on your water heating bills.
  • In a typical residential house or apartment, a person can consume 20-35 gallons of water each day.
  • However, because of the increased need for hot water in a big home, a higher hot water temperature may be preferred.

3. Pipe Size

  1. What is the impact of the domestic pipeline system on the hot water consumption of your family?
  2. Increases in both flow rate and pressure are associated with decreasing internal diameter of the pipe.
  3. When using a tiny bore pipe system, it will take a long time for hot water to reach your faucets, as an example.
  • As a result, heat will evaporate throughout the journey.
  • If you have a bigger home or property, you should consider building a hot water recirculating system so that hot water can be delivered to your plumbing system more quickly and efficiently.
  • It also implies that you will no longer be required to operate at a high temperature all of the time, resulting in a significant reduction in energy use.

4. Non-Preheat Dishwasher

The majority of modern dishwashers nowadays are equipped with pre-heating technology, which boosts the temperature of the incoming water before it is used. The water heater should be heated to 140 degrees Fahrenheit if your dishwasher does not warm the water before use. This will provide the appropriate sanitizing temperature.

5. Ambient Outdoor Temperature

  1. The temperature level at which we should set our water heater is heavily influenced by the weather conditions outside our home.
  2. It is possible that your hot water production will be affected by the unpredictable weather outdoors.
  3. For example, during the winter months, the water that enters your pipes will be cooler than during the summer months.
  • As a result, your heater will have to work more as a result of this.

5 Quick and Easy Energy-saving Tips for Water Heater

1. Lower The Temperature On The Thermostat

We may save anywhere from 12 to 30 dollars each year for every 10 degrees we lower the temperature, according to a Department of Energy research.

2. Reduce Hot Water Usage & Insulate Water Tank

  1. When doing actions that do not necessitate the use of warm water, such as brushing your teeth, it is more effective to switch off the water heater.
  2. Additionally, a lack of insulation might result in the consumption of additional energy.
  3. If your water heater’s tank is not properly insulated, it will cool more quickly.
  • As a result, it will take a long time for the entering cold water to be converted into hot water, particularly if the weather is very cold.

3. Insulate The Water Heater Pipes

It is necessary to insulate the hot water pipelines in addition to the tank since doing so will assist to decrease standby heat losses and will protect your tank from bursting, which can be caused by freezing conditions. Because you won’t have to switch on your water heater as frequently as you would otherwise, this added protection will help increase the longevity of your water heater.

4. Inspect And Repair Leaky Valves

A leak in a water heater is a common problem that most homeowners have to deal with. The majority of the time, excessive water pressure is the source of the leakage. This is not a problem to be taken lightly, as it has the potential to harm the water heater and waste more than 90 gallons of water every day.

5. Drain Sediment From The Tank

Tank drainage should be performed once every six months since sediment buildups tend to accumulate at the bottom of the tank and increase the heater’s power usage.


  1. ‘What temperature should I set my hot water heater to?’ is a question that many people have.
  2. I hope you’ve gotten a better grasp of how to correctly manage the temperature of your own water heater as a result of this article.

  2. Indeed, while the majority of people don’t give their hot water heater settings a second thought, they are actually highly critical in many situations.
  3. Not only will it save you money, but it will also make your showering experience more pleasant as a result of it.
  • Here is a breakdown of the procedures.

Default Hot Water Heater Settings Can Vary

Water heaters in Phoenix are frequently shipped with preset temperature settings that are as high as 140 degrees Fahrenheit or more.That is far greater than the majority of individuals require, although manufacturers do so for a variety of reasons.For starters, germs cannot thrive in water that hot, according to the Department of Energy.Increased gas or electric water heater settings can be beneficial for people who have weakened immune systems or respiratory illnesses.

In addition to impressing consumers who have presumably recently replaced their tank since the previous one had ceased performing correctly, high temperatures can also be beneficial.Once this psychological trick wears off (and assuming you don’t have a sickness that makes you particularly susceptible to bacteria), you’ll likely receive far more joy from saving money on your water bill, which we’ll teach you how to achieve in the next section.

How Much Are Your Gas and Electric Hot Water Heater Temperature Settings Costing You?

As a general rule, every 20 degrees you reduce the temperature of your gas or electric water heater, you may expect to save as much as ten percent on your utility bill.That’s not too shabby after all!In reality, it adds up over time, and you can almost certainly come up with a number of better uses for the money you save.″But hold on a minute,″ you may be thinking.

″I really enjoy taking hot baths!″ However, you almost probably do not take showers above 140 degrees Fahrenheit, which can cause scorching because of the high temperature.It’s conceivable that you won’t even notice a difference.No matter what happens, raising the temperature is a simple process.It has also been known to cause aged hot water heaters to stop functioning.

How To Adjust Your Gas and Electric Hot Water Heater Temperature Settings

Now that you understand why you should reduce the temperature of your water heater, let’s have a look at how to go about doing so effectively.

Step One: Get An Accurate Temperature Reading

It’s likely that the thermostat dial linked to your water heater tank is not functioning properly.As a result, you should really use a thermometer to monitor the temperature of the water flowing out of your faucet.The Department of Energy suggests that you measure the amount of water that is flowing out of the faucet that is the furthest away from your water heating system.Make a note of the settings after you’ve found them.

Step Two: Figure Out Where to Make the Adjustment

There are several distinct types of water heaters, and we’ll go through each of them separately.

Electric Water Heater Settings

In the case of an electric water heater, you must modify the hot water settings at the top and bottom of the unit. Both controls, which are often concealed behind a panel and consist of knobs that you crank to establish the appropriate electric water heater thermostat settings, are typically located on the same side of the panel.

Gas Water Heater Settings

Newer gas water heaters are equipped with temperature controls that are similar to those described above in the section on electric water heaters. Most gas heaters, especially older models, feature a temperature knob near the base that may be easily adjusted to the appropriate temperature.

Tankless Water Heater Settings

Finally, tankless water heaters are available.This is likely the simplest modification to make because most thermostats include an LED screen that allows you to directly control the thermostat’s temperature.In addition to being convenient, these systems frequently allow you to modify the tankless water heater settings more accurately than you could with traditional dial-based adjustment methods.

Step Three: Make The Adjustments

If you have an electric unit, make sure to turn off the electricity to it before modifying the hot water heater settings at the top and bottom, as we previously discussed in detail.This may be accomplished simply turning off the necessary settings on your circuit breaker panel.Doing so is also recommended in the case of a gas water heater that consumes some power (as some newer units do).But hold on a minute!

What temperature should you choose as a starting point?The Department of Energy suggests that you set your heater to 120 degrees Fahrenheit for the best performance.That should be sufficient heat for the majority of applications in your house.Some water heater temperature controls now include buttons that read ″A-B-C″ instead of numbers, which makes them easier to use.Generally speaking, A denotes 120 degrees, B denotes 130 degrees, and C denotes 140 degrees, respectively.

To double-check these settings, consult the owner’s handbook for your water heater.

Step Four: Tweak the Settings as Necessary

After you’ve made the necessary adjustments to your gas or electric water heater thermostat settings, you may discover that you need to make a few more adjustments to get the best setting. You’re trying to strike the perfect balance between comfort and cost-effectiveness. If that’s more than 120 degrees Fahrenheit for you, there’s nothing wrong with that. Make the necessary adjustments!

Frequently Asked Questions

What Is The Maximum Temperature For A Water Heater?

The highest temperature setting for the majority of water heaters is 150 degrees Fahrenheit.

Is 140 Too Hot For A Water Heater?

Yes, temperatures above 140 degrees Fahrenheit are uncomfortable for the majority of people.The only exception would be persons who require an additional layer of protection against germs, which cannot thrive in water at that temperature.However, because such a state does not protect you from scorching, you will almost certainly need to install an equipment at the showerhead that cools the water before it is discharged from the showerhead.

Why Is My Water So Hot?

If you haven’t changed the settings on your hot water heater in a long time, they are most likely still set to the factory default of 140 degrees. The latter is especially true if your hot water heater was only recently installed; the old one was almost certainly altered at some time over the years, whereas the new one is set to the manufacturer’s recommended settings.

What Is The BEST Water Heater Temperature Setting?

Your hot water heater settings are most likely remain at the factory default temperature of 140 degrees if you haven’t changed them in a long while. The latter is especially true if your hot water heater was only recently installed; the old one was almost certainly altered at some time over the years, whereas the new one is set to the manufacturer’s recommended temperature.

How To Check Your Water Heater Temperature

The majority of water heaters do not have a temperature gauge with a digital readout on them.A temperature or heating range is marked on the thermostat, rather than a number.A cup and a culinary thermometer will be required in order to correctly determine the temperature of the hot water heater.If you haven’t used your water heater in at least one hour, turn on the faucet that is nearest to it.

Allow the water to run for at least one minute to ensure that the water is at its warmest possible temperature before filling the cup with it.Insert your cooking thermometer and make any necessary adjustments to the temperature settings.

Recommended Temperature Settings

Water heaters are pre-programmed to operate at temperatures about 140 degrees Fahrenheit, which is recommended by OSHA.The Environmental Protection Agency, on the other hand, recommends lowering the thermostat down to 120 degrees Fahrenheit to save power use and using a booster heater to attain sanitizing temperatures at certain outlets.Another point of view is that lower temperatures are preferable for homes with little children, although higher temperatures are more effective in cleaning and sanitizing surfaces.Recommendation from me Personally, I feel that the temperature of a water heater should be set around 130 degrees in practically all circumstances.

However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.

How To Turn Up Your Water Heater

If you are dissatisfied with the suggested temperature of your hot water heater, you may alter the settings to receive extra hot water.Although electric water heaters may require a screwdriver and potentially a tiny wrench or socket, most hot water heater settings are straightforward to modify.Keep in mind that the thermostat is factory configured to a recommended temperature, and that altering the setting may increase the risk of significant burns from the appliance.

How to Set Temperature on a Gas Water Heater

  • The temperature of a gas water heater may be adjusted by turning the setting knob on the water heater. The majority of gas control valves have a knob with different designations on them, such as A-B-C. Control valves for gas water heaters may be labeled differently depending on the manufacturer. In the majority of circumstances, the following is what each label indicates: Temperatures range from 80-90 degrees
  • hot (or triangle sign) = 120 degrees
  • A = 130 degrees
  • B = 140 degrees
  • C = 150 degrees
  • Very Hot = 160 degrees

There is a ″Vacation″ setting that appears from time to time. This does not heat the water, but it does ensure that the pilot light remains lit.

How to Set Temperature on an Electric Water Heater

Turn off the circuit breaker if necessary. Remove the access panels from the room. Under the insulation, look for the thermostat adjustment screwhole. Adjust the thermostat control to the appropriate temperature by using a straight screwdriver to make the adjustment. After replacing the insulation and panels, the power should be restored. Here’s a good video that demonstrates the procedure:

Factors That Affect Water Temperature

Some of the things that may influence the temperature of your hot water include the distance between the water heater and the outlet, the way the pipes are built, and the quality of the heating element itself, among others.Because of the length of the pipe and the small bore size, it will take longer for the hot water to reach the opening.Additionally, pipes that run beneath or outside the residence may be exposed to freezing or freezing temperatures in the winter and summer.If you have a big house, you may want to consider installing a hot water recirculation system, which may reduce the amount of time it takes to send hot water to all of the outlets in the house, as well as provide significant cost savings over time.

If setting the thermostat does not result in the desired temperature, it is possible that the water heater element has to be replaced.Alternatively, if you don’t notice a difference in water temperature after changing the thermostat, it’s likely that you have a malfunctioning thermostat that has to be replaced.

What Temperature Should a Hot Water Heater Be Set at?

What temperature should a hot water heater be set at?Do you have the same question as many other people?Setting the water heater to the proper temperature is critical for providing not just more pleasurable showers, but also longer showers.It also protects individuals from contracting infections.

This page provides answers to your most often asked questions about the optimal hot water temperature.We’ll also go through some of the considerations you should keep in mind while adjusting the heater’s thermostat.Let’s get this party started.

What is the Ideal Temperature Setting of a Water Heater?

There are two schools of thinking that can throw light on the topic of what temperature should be set for a water heater.Water heater manufacturers set the temperature of their water heaters to 140 degrees Fahrenheit by default, believing that the temperature is more calming and pleasant for the majority of people.According to the Occupational Safety and Health Administration, this water heater setting should be used to prevent the growth and multiplication of Legionella and other dangerous germs in water heaters.According to the Mayo Clinic, Legionella bacteria may be found in both water and soil as non-infectious agents that do not cause disease.

In contrast, when these bacteria multiply in water systems, such as those found in air conditioning units and household plumbing, they have the potential to become harmful.People become infected with Legionella bacteria when they inhale water droplets containing the bacteria when showering or utilizing whirlpools, hot tubs, water heaters, or hot water tanks.Alternatively, the United States Department of Energy and the Environmental Protection Agency have determined that the optimal water temperature is 120 degrees Fahrenheit (or below).Medical and healthcare professionals have also chimed in on the controversy, advising that the hot water heater temperature setting should not be lower than 120 degrees Fahrenheit in order to avoid microbial development in the water heater.The position of the Consumer Product Safety Commission, which recommends a maximum water temperature of 120 degrees Fahrenheit for safety reasons, further complicates the situation.

According to the organization, hot water (over 120 degrees Fahrenheit) might induce burn injuries in persons who are vulnerable to them.The recommended temperature of 120 degrees Fahrenheit is likely to be appropriate for most people’s households.Unfortunately, no two families or homes are comparable in their characteristics.

As a result, it would be wise to analyze the role that various components play in the overall equation.

What Factors Should You Consider When Setting the Water Heater’s Thermostat?

People have varying opinions on what temperature hot water should be at the optimal time of day. It’s possible that I favor 120 degrees, while you or other individuals could prefer 130 or 140 degrees. Regardless of the sort of water heater you have, it is recommended that you take the following aspects into consideration.


In accordance with the American Burn Association, children under the age of 16 account for 26 percent of all admissions to burn treatment facilities.According to the organization, younger children are more susceptible to scorching injuries because of their weak cognitive and physical abilities, as well as a lack of parental supervision when using hot water, among other factors.Young children also lack the ability to perform self-rescue maneuvers.Because of pre-existing medical issues, slower response time, and decreased mobility, the elderly are particularly vulnerable to hot water-related burn injuries.

In addition, as compared to other age groups, both children and the elderly have smaller skin layer thicknesses.Even when exposed to hot water for a short period of time or when the water temperature is modest, they might sustain severe burn damage.According to the American Burn Association, three seconds of exposure to 140-degree Fahrenheit water is all it takes to create major burn injuries that necessitates surgical intervention.Because of this, you could believe that a hot water heater setting of 140 degrees Fahrenheit is safe for you.You must, however, lower the temperature in your home to 120 degrees Fahrenheit if you have children or elderly members of your household.

Immune System Functioning

We require a properly functional immune system in order to defend ourselves against infections.Whenever an organism infiltrates our body, the immune system mobilizes an army of defense cells to combat the invasion.Because immune-compromised individuals no longer have a powerful defense army in their bodies, they are more susceptible to infection than the general population.Increased water temperatures may be required to destroy germs in those who have lowered immune system capabilities.

People who use immunosuppressive drugs are unable to protect themselves against infections.In addition to corticosteroids, monoclonal antibodies and biologics, and calcineurin inhibitors are examples of immunosuppressive medications.People suffering from HIV/AIDS, psoriasis, Crohn’s disease, rheumatoid arthritis, and lupus are all affected in the same way.Patients undergoing organ transplant procedures also have compromised immune systems, which makes them more susceptible to infection than the general population.In houses with immunocompromised individuals, 140 degrees Fahrenheit is the best temperature for domestic hot water to be provided.

While certain bacteria are thermophilic or heat-resistant, the vast majority of them cannot endure temperatures beyond 140 degrees Fahrenheit.Even the deadly Legionella bacteria will perish at 122 degrees Fahrenheit (50 degrees Celsius).Unfortunately, certain heat-resistant viruses must be inactivated at temperatures greater than 140 degrees Fahrenheit in order to be killed.

Families with immunocompromised individuals should adjust the water heater temperature to 140 degrees Fahrenheit, regardless of the reason.

Energy Consumption

According to the United States Department of Energy, adjusting the water heater to 120 degrees Fahrenheit can result in yearly energy savings ranging from 4 percent to 22 percent.It is estimated that the savings will come from lower demand losses (at least $400 per year) as well as lower standby losses (between $36 and $61 per year).When it comes to your water heater, if you are concerned about your power costs, you may want to keep the temperature no higher than 120 degrees Fahrenheit.Naturally, if money is not an issue, you may always raise the temperature to 140 degrees Fahrenheit on a regular basis.

Once again, I strongly advise you to take into account the age and immunological health of your family members while determining the optimal water heater setting.

Water Appliances’ Energy-efficiency

The ″water preheat″ function on some dishwashers does not allow customers to adjust the temperature of the water heater’s thermostat setting to a more comfortable level. Those who own such a dishwasher are compelled to set the water heater to 140 degrees Fahrenheit as a matter of necessity.


  • When it comes to the topic ″what temperature should a hot water heater be set at,″ you have two options. Turn down the temperature of your water heater to 120 degrees Fahrenheit if you want to save money on electricity or if you have elderly or young children in the house.
  • If you have members of your household who are immunocompromised or if you don’t mind spending a huge power bill, set the water heater’s temperature to 140 degrees Fahrenheit or higher. If you have a dishwasher that does not have a preheat feature, you may additionally require this option.

Understanding the numerous elements that influence hot water temperature is essential to determining the optimal temperature.

What’s The 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. Any temperature below 120 degrees Fahrenheit, according to the majority of experts, increases the likelihood that germs from stagnant water, such as the bacterium legionella, which causes Legionnaire’s disease, would form within your water heater. 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. There are, however, a number of elements to take into consideration when determining your thermostat setting: Stick with 120°F if you have small children and/or the elderly in your house who are prone to third-degree burns in seconds, or if you are a single occupant owing to the decreased demand for hot water in your home.
  • Consider 140°F if you have an immunocompromised individual in your home, a dishwasher that does not pre-heat, or a multi-occupant household 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!If you’re still on the fence, play around with it.Many hot water heaters are equipped with a temperature control dial.

If yours does not, run the water for a few minutes and use a thermometer to check the temperature of the water thereafter.Start with 120°F and gradually increase the temperature in small increments until you get your desired result.All things considered, it is possible that your house is not as simple as ″simply″ setting a temperature and forgetting about it.

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.To inhibit pathogens from growing in your tank, it retains the temperature at 140°F while mixing with cold water to provide a lower temperature at the faucet.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).A hot water circulating system circulates hot water gently through the pipes so that you are not forced to wait.

  • Whatever you choose, we’re only a phone call away if you’re having issues with your hot water!

What setting should a water heater be on?

How can you determine what temperature range is most appropriate for your water heater? 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.

How to adjust your water heater temperature

No one enjoys taking a cold shower.Even worse is being scalded by hot water when you are using it in the shower.Maintaining the proper temperature on your water heater is vital not just for your health and safety, but it also allows you 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

    There are a number of reasons your water heater should be set within a specific range of temperatures. If it’s set too low, not only will your hot water feel lukewarm, at best, it can also lead to bacterial growth which can cause things like Legionnaires’ disease. This can be prevented by setting the water heater to a temperature where the bacteria Legionella cannot thrive. The Occupational Safety & Health Administration (OSHA) recommends water heaters be set to at least 140 degrees Fahrenheit (60 degrees Celsius) to minimize the growth of Legionella and other microorganisms.While you might be prone to just crank up the heat, water that is too hot is potentially more dangerous, especially if you have kids around the house. At 150 degrees Fahrenheit (66 degrees Celsius), it only takes two seconds to suffer third-degree burns. The Consumer Product Safety Commission (CPSC) recommends setting the water heater at no more than 120 degrees Fahrenheit (49 degrees Celsius) to prevent scalding. Not to mention, a water heater that is set too high can unnecessarily increase your electricity bill. Of course, every house is different. The further a faucet is from the water heater, the more heat will be lost as the water travels, especially if the pipes aren’t insulated. That means you might have to raise the temperature beyond the recommended 120 degrees Fahrenheit (49 degrees Celsius) to compensate.Use your best judgement for your family and household when setting thetemperature. It’s smart to stay within the range of 120 to 140 degreesFahrenheit (49 to 60 degrees Celsius). Make an adjustment, test it out and repeat until you settle on the perfect temperature setting for you home and water heater. Now playing: Watch this: Step inside CNET’s Guide to Smart Living 1:00
