Adjusting Your Water Heater Settings: How To Maximize Efficiency

  1. Not many people are aware that selecting the proper water heater settings may result in substantial savings.
  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.
  4. Here is a breakdown of the procedures.

Default Hot Water Heater Settings Can Vary

  1. Water heaters in Phoenix are frequently shipped with preset temperature settings that are as high as 140 degrees Fahrenheit or more.
  2. That is far greater than the majority of individuals require, although manufacturers do so for a variety of reasons.
  3. For starters, germs cannot thrive in water that hot, according to the Department of Energy.
  4. Increased gas or electric water heater settings can be beneficial for people who have weakened immune systems or respiratory illnesses.
  5. 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.
  6. 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?

  1. 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.
  2. That’s not too shabby after all!
  3. In fact, it adds up over time, and you can almost certainly come up with a number of better uses for the money you save.
  4. ″But hold on a minute,″ you may be thinking.
  5. ″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.
  6. 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

  1. It’s likely that the thermostat dial linked to your water heater tank is not functioning properly.
  2. As a result, you should really use a thermometer to monitor the temperature of the water flowing out of your faucet.
  3. 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.
  4. 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

  1. Finally, tankless water heaters are available.
  2. 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.
  3. 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

  1. 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.
  2. This may be accomplished simply turning off the necessary settings on your circuit breaker panel.
  3. Doing so is also recommended in the case of a gas water heater that consumes some power (as some newer units do).
  4. But hold on a minute!
  5. What temperature should you choose as a starting point?
  6. 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!

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 prefer 120 degrees, but you or other people might prefer 130 or 140 degrees. Regardless of the type of water heater you have, it is recommended that you take the following factors into consideration.


  1. In accordance with the American Burn Association, children under the age of 16 account for 26 percent of all admissions to burn treatment facilities.
  2. 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.
  3. Young children also lack the ability to perform self-rescue maneuvers.
  4. Because of pre-existing medical issues, slower response time, and decreased mobility, the elderly are particularly vulnerable to hot water-related burn injuries.
  5. In addition, as compared to other age groups, both children and the elderly have smaller skin layer thicknesses.
  6. 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

  1. We require a properly functional immune system in order to defend ourselves against infections.
  2. Whenever an organism infiltrates our body, the immune system mobilizes an army of defense cells to combat the invasion.
  3. Because immune-compromised individuals no longer have a powerful defense army in their bodies, they are more susceptible to infection than the general population.
  4. Increased water temperatures may be required to destroy germs in those who have lowered immune system capabilities.
  5. People who use immunosuppressive drugs are unable to protect themselves against infections.
  6. 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

  1. 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.
  2. 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).
  3. 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.
  4. Naturally, if money is not an issue, you may always raise the temperature to 140 degrees Fahrenheit on a regular basis.
  5. 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.
  1. But what about the expenses of energy?
  2. We get what you’re saying!
  3. Water heaters account for around 14-18 percent of the total energy consumed by a residence on a typical day.
  4. Furthermore, it may be tempting to lower the temperature in order to save money.
  5. It should be noted that a 10°F decrease in temperature is related with a 3-5 percent reduction in energy use.
  6. 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!

  • The process of washing clothes may be divided into four parts: time, water, mechanical action, and chemicals.
  • Time, water, mechanical action, and chemicals are divided into four parts.
  • Here’s when the monkey wrench comes in — A few things are altered by the use of cold water.
  • You will have to run your machine for longer periods of time and/or use more chemicals (soap) while washing with cold water.
  • On the drying side of things, your garments may have to be dried for a longer period of time in the dryer.
  • This is due to the fact that cold water weighs more than warm water, causing natural materials such as cotton to absorb more water, increasing the amount of time it takes to dry.
  • Hot water is typically 10 degrees cooler when it arrives at your machine than it is when it leaves your hot water heater when it leaves your hot water heater.
  • In the context of clothes washing, hot water is defined as water that is 130 degrees Fahrenheit (54.4 degrees Celsius) or above.

  • in a nutshell….
  • Increased wash time (or the use of more chemicals) in cold water, as well as the possibility of a lengthier drying time.
  • Washing using hot water reduces the amount of time spent washing (or reducing the amount of chemicals used), and drying time can be reduced.

Cleaning and Sanitizing Power vs Energy Efficiency

  1. When dealing with extremely dirty objects, you may want to rethink whether it’s worth it to save a few pennies or a few watts in exchange for a few extra cents or watts.
  2. Hot water is a waste of resources.
  3. If your machine is not High Efficiency, you might be wasting up to 40 gallons of water every hour.
  4. However, if you need to get things extremely clean and eradicate germs, it isn’t a waste of time.
  5. For the safety of those in your home who are sick or have a weaker immune system, it is recommended that you use hotter water settings while washing.
  6. It is absolutely necessary to wash things like cloth diapers on a warm or hot setting.
  • Hot water is preferred for disinfection, while the Centers for Disease Control and Prevention (CDC) recommend washing things at 160°F for 25 minutes to eradicate germs using only detergent.
  • Germs can also be killed by the ultraviolet (UV) rays of the sun.
  • The sun is free — and while your clothes are drying on the clothesline, it will eliminate microorganisms on them.
  • Alternatively, if your clothing come out a bit stiff after hanging, you may put them in the dryer for 10 minutes, which will still result in you using far less power to dry them.
  • Dryer Balls are another another money-saving tool in the drying area.
  • Those are fantastic since they assist to reduce drying time and are a fantastic investment.
  • Although Eco Nuts may be used in place of fabric softener when washing with them, if you’re using a different detergent, they can be used to soften clothes rather well.
  • Returning to the question of cleaning power, it is nearly always preferable to remove bodily fluids from materials at a higher temperature.
  • The reason for this is because your body is heated, and at that temperature, those fluids become soluble.
  • If you need to eliminate fluids from your skin such as urine, blood, or perspiration, a WARM (not hot) rinse is the best option.
  • Because certain materials (particularly blood) can establish stains at higher temperatures, you want to introduce a dirty cloth to water while it is still warm when you do so.
  • Warm and hot water have the most cleaning power because it accelerates the chemical reaction of the soap, which removes the dirt and grime.

The higher the temperature of the water, the more soluble most soils are and the easier it is to remove them.Not to mention that many detergents (but not all) are specifically made for use in cold water washing, thus washing your garments in cold water will not result in a longer drying time if you are using a cold water-formulated detergent.

Washing Machine Maintenance

  1. Washing machine maintenance is sometimes forgotten, but it is important to consider it when determining your preferred water temperature.
  2. When you use cold water in your washing machine, gunk accumulates more quickly, resulting in you having to contact the repair guy more frequently.
  3. The same reason that hot water makes it easier to remove dirt from clothes also makes it easier to keep buildup out of your washing machine.
  4. Washing with cold water and using more detergent to compensate for the cold water can increase the likelihood of a buildup problem in the machine.
  5. On a badly stained garment, you can get away with using warm water rather of hot water 99 percent of the time instead of hot water.
  6. When you use warm water instead of hot, you may save up to half the energy required by hot water while still receiving the majority of the dirt removal advantages.
  • You should consider conducting some washing machine maintenance once a month with a few hot water cycles and no garments if you chose to wash on cold most of the time or all of the time.
  • Depending on the detergent you are using, you may see a lot of bubbles coming out of the machine.
  • This is the detergent residue that has become caught in the machine and is being expelled by the machine.
  • It is possible to speed up the washing machine strip by adding vinegar or Eco Nuts Liquid Detergent to the hot water.
  • This will assist in the elimination of the muck that has accumulated in the machine.
  • Recommendations from Me My basic advice are to wash your clothes in a mixture of water temperatures that correspond to the temperatures listed on the labels of your clothing, and to organize your goods in the same manner.
  • In other cases, it may be more expensive or just not worth it to purchase new clothes (or to suffer through the mental pain that comes with having to retire an old favorite due to a laundry mistake).
  • This will depend on your spending habits and how connected you are to your clothes.
  • If you follow these instructions, your washing machine maintenance will be taken care of automatically as well.
  • For around 90 percent of my personal laundry, I use a combination of cold and warm water temperatures.
  • Many textiles will also last longer if they are washed in cold water (which is why it is crucial to follow the instructions on the label).
  • It’s possible that your priorities differ from mine – therefore feel free to express your disagreement.

Now, dear readers, what is the highest temperature at which you wash your clothes?Is it cold or warm?Is it a combination?

Why Your Hot Water Doesn’t Last Long Enough

  • Have you ever gotten into a hot shower only to have it turn icy cold seconds later? The worst part is that it happens every day, whether it’s the alarm in the morning or the bedtime routine at night. Here are a few tips and suggestions from Warner Service Inc. in order to keep the hot water flowing for longer: Increase the temperature setting on the hot water heater. One of the most straightforward methods to extend the duration of a hot shower is to use less hot water while the water is still at a high temperature. To accomplish this, raise the temperature setting on the thermostat that is linked to the hot water heater tank, as shown below. (This is not the thermostat mounted on the wall.)
  • Shower with a low-flow showerhead. If you haven’t changed your shower head yet, consider switching to a low-flow one. The apertures in these plumbing equipment are smaller, allowing the water to exit more quickly. This naturally pressurizes the water and drives it out at a slower rate than would otherwise be the case.
  • Keep an eye out for alternate sources of hot water in your home. The shower isn’t the only spot in your house where you’ll find hot water. Even if the dishwasher and washing machine are not in use at the same time, they have an impact on the amount of hot water available. Washing the dishes after a hot shower and doing laundry with cold water are good ideas. Insulate the domestic pipes as well. In order to enhance the insulation of home hot water pipes, a plumbing specialist should be called in. Hot water leaves the heating tank and travels through pipes to the shower, washing machine, and dishwasher, among other places to use. The water can quickly lose its heat while traveling through pipe to reach faucets or shower heads if the piping is not properly insulated. Inspect the heating components. The hot water heater might be the source of the plumbing issue with the hot water, if that is the case. Water will not be heated to the temperature specified on the tank’s thermostat if the heating element is not operating properly. The heating element’s size varies based on the type of energy source it employs (gas, solar, or electric). Elements may be simply updated and frequently enhance the overall operation of the hot water system.
  • Perform regular maintenance on the hot water tank
  • A badly maintained hot water tank is one of the most common plumbing problems associated with a hot water system. Sediment and rust accumulate in the tank’s inside. This has the effect of lowering the water quality and slowing the effects of the heating element. These plumbing issues may be resolved with a simple draining and cleaning procedure. A plumbing specialist can execute this job in a short amount of time.
  • The hot water tank should be replaced or supplemented. If your hot water system isn’t operating properly, you should consider upgrading the complete system. Even though many hot water systems only have a single heater tank, it is feasible to install a second tank in order to boost performance. Additionally, modern heater tanks are a better alternative for older homes that require renovations. Consider installing a tankless water heater. The water heater is responsible for providing your home with a plumbing system that provides hot water for all of your needs. Tankless water heaters are more energy efficient and help you save money on your utility costs.

In addition to plumbing maintenance, Warner Service can assist with appliance replacements. You may also download the Boiler Maintenance Checklist, which will help you keep the hot water running throughout the winter. To get started, simply click on the button below:

How to adjust your water heater temperature

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
