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.
The time it takes for third-degree burns to occur at 150 degrees Fahrenheit (66 degrees Celsius) is less than two seconds.
- Not to mention that a water heater that is set too hot might result in an excessively expensive power bill.
- The greater the distance between a faucet and the water heater, the greater the amount of heat that will be lost as the water flows, especially if the pipes are not insulated.
- When determining the appropriate temperature for your family and household, use your best judgment.
- 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.
The process of adjusting a tankless water heater is quite similar to the process of adjusting your air conditioning thermostat. Adjust the temperature by using the digital control panel, which may be adjusted up or down as desired.
Gas or electric water heaters
Some gas water heaters include a dial towards the bottom of the device that may be adjusted simply by turning it – no tools are required for this operation. Nonetheless, most current tank water heaters (whether gas or electric) require a bit more effort, but the process is still straightforward and should only take a few minutes.
- Turning off the water heater’s electricity at the circuit breaker is the first step. To remove a thermostat(s), locate the access panel for the thermostat(s) and remove it using a screwdriver
- Remove the insulation by peeling it back. To adjust the thermostat, use a flathead screwdriver to turn it up or down.
- If your water heater has two thermostats, make sure they are both set to the same temperature. The temperature on the top thermostat should be a few degrees higher than on the bottom thermostat.
- Replace the insulation and re-install the access panel, if necessary. Reconnect the water heater’s power supply
- It is possible that you may need to relight the pilot light on a gas water heater.
Once you’ve made the necessary adjustments, you should wait at least three hours before checking the water temperature once more. It is possible that you may need to make more modifications in order to get the desired temperature. If you’ve increased the temperature and are still getting chilly showers, it’s possible that your hot water heater has to be serviced or completely replaced.

- Make sure to run hot water for at least three minutes from the faucet nearest to the water heater. Fill a glass with hot water and check the temperature
- If the water temperature is higher than 120 degrees, adjust the dial, wait approximately three hours, and then check again. Continue until the water reaches 120 degrees Fahrenheit.
The temperature of the water heater should be checked the next morning before anyone uses any hot water as a last check. Once you have found the perfect setting, make a note of it on the dial so that you do not have to go through the testing procedure again. Here are some more suggestions for extending the life of your water heater.
You might be wondering how to adjust the temperature of your hot water heater. In this section, you will learn all you need to know about your gas or electric water heater thermostat, including how to adjust your hot water heater temperature thermostat and what temperature is optimum for hot water.
What’s the Right Temperature for a Hot Water Heater?
It’s an often asked question: what is the optimal temperature for hot water? Setting a tank-based hot water heater to 120 degrees Fahrenheit is recommended by the United States Department of Energy. If you have never changed the temperature of your hot water heater, it is most likely set to the 140-degree Fahrenheit level that is recommended by most manufacturers of hot water heaters. What is the significance of adhering to this temperature standard?
If the temperature setting on the water heater thermostat is set too high, the water will be excessively hot and might cause burning or scorching. If it is set too low, germs may be able to flourish, leading to the spread of water-borne illnesses.
How to Set Your Hot Water Heater Temperature Thermostat Setting
Before you make any modifications to the temperature thermostat setting on your hot water heater, you should first ascertain what the current temperature is set at so that you can establish how much you need to alter the settings. A conventional cooking thermometer may be used to quickly and accurately detect the temperature. You should calibrate your thermometer once you have determined the current temperature setting. Fill a cup halfway with cold water and submerge your thermometer until the temperature dial reaches 32 degrees, or the lowest temperature displayed on your thermometer’s gauge, and then remove it.
Meanwhile, locate the faucet that is closest to the water heater and turn it on until it is hot (while you are calibrating your thermometer).
If your thermostat is set too high, the temperature may be high enough to burn you.
Adjusting aGasHot Water Heater Temperature Thermostat Setting
The majority of gas water heaters are straightforward due to the presence of a clearly readable dial at the bottom of the tank’s bottom section. If you follow the methods outlined below, it is simple and straightforward to alter this dial.
- The majority of gas water heaters are straightforward due to the presence of a clearly viewable dial at the bottom of the tank’s bottom chamber. If you follow the methods outlined below, adjusting this dial will be straightforward and easy.
Adjusting anElectricHot Water Heater Temperature Thermostat Setting
The process of adjusting the temperature thermostat setting on an electric hot water heater is a little more difficult, but still pretty simple. The vast majority of electric water heaters are equipped with two thermostats: an upper and a lower thermostat, both of which are placed beneath two control panels. Setting both thermostats to the same temperature can help to guarantee that your electric water heater operates as effectively as possible. One thing to keep in mind is that some tiny electric hot water heaters only have one thermostat.
Here’s how to adjust the temperature on your electric hot water heater thermostat:
Please keep in mind that you will want a screwdriver to execute the following procedures in order to alter the temperature of your water heater.
- To execute the next tasks, you’ll need a screwdriver to alter the temperature setting on your water heater.
Other Considerations: Water Heater Thermostat Setting Safety
There is one thing you should be aware of: your water heater is fitted with something known as a temperature and pressure relief valve, abbreviated “T P valve.” These can become worn out over time, and one sign that they should be replaced is the presence of water leaking through. This is a very crucial safety feature. If your unit is old, or if your hot water heater pressure relief valve is leaking after it has been replaced, get it examined by a competent plumbing professional.
How to Adjust a Hot Water Heater
Documentation Download Documentation Download Documentation There is a delicate balance between the temperature of the water in your home—too high, and you run the danger of getting scalded; too low, and you’ll be shivering in your shower. Fortunately, regulating a hot water heater is a straightforward process if you go with caution. For your own safety, turn off the electricity to the water heater at the main circuit breaker in your home’s electrical panel. Afterwards, remove the access panel from the unit’s side and use a flat-blade screwdriver to increase or reduce the temperature in accordance with the temperature ranges specified on the control dial.
When you’re finished, make sure to check the temperature of your water before getting into the shower.
- 1 Determine whether or not the temperature of your water has to be adjusted. Most manufacturers recommend that the water used in your homestay be kept at a temperature of roughly 120 degrees Fahrenheit (49 degrees Celsius) for safety reasons. The temperature of most water heaters will already be adjusted to this level when they are installed. In most circumstances, it is advisable to simply leave it alone in order to reduce the danger of harm.
- Instead of the water heater’s temperature being the source of the problem, it’s possible that a faulty heating element or inadequate insulation is to blame. A trained plumber can assist you in diagnosing and repairing a malfunctioning water heater.
- 2 To adjust the temperature of the water heater, turn the dial on the bottom of the unit. Gas water heaters are simple to use
- They are controlled by a single knob that regulates the quantity of heat provided to the unit. Turning this knob to the left (counterclockwise) will raise the temperature, which will result in hotter water being produced. It will cool down if you turn it to the right (counter-clockwise).
- The lower temperature range of the vast majority of gas water heaters will be anywhere between 90 and 110 degrees Fahrenheit (32 and 43 degrees Celsius), while the upper temperature range will peak at roughly 140–150 degrees Fahrenheit (60 and 66 degrees Celsius). It’s possible that the dial on your gas water heater isn’t numbered, which makes determining the ideal temperature a little more difficult. To get around this, just take the temperature of the water several times after making changes to your settings and write the exact degree reading on a piece of paper or on the dial itself.
- Gas water heaters have a temperature range of 90–110 °F (32–43 °C) at their lowest setting, and an upper temperature range of 140–150 °F (60–66 °C) at their highest setting, for the most part. It’s possible that the dial on your gas water heater isn’t numbered, making finding the ideal temperature a little more challenging. To get around this, just take the temperature of the water several times after making changes to your settings and note the exact degree reading on a piece of paper or on the dial itself
- Heat is more effective in killing most common bacteria, including health-threatening pathogens such as Legionella, E. coli, and staphylococcus
- Higher temperatures kill more germs. Avoid heating your water to a temperature greater than 120 degrees Fahrenheit (49 degrees Celsius). A substantial danger of burns, particularly for youngsters and the elderly, can result from this practice.
- Increase the temperature in order to save money on your energy bills. Heating significant amounts of water quickly becomes prohibitively costly. Lowering the temperature of your water heater to the range of 100–110 degrees Fahrenheit (38–43 degrees Celsius) will help you save money on your next heating bill. Even a minor adjustment can result in significant savings over the course of a few months.
- Be aware that your water will not be as hot, which may have an influence on your comfort or the degree of sanitation for cleaning tasks.
- Step 1: Turn off the electricity to the water heater. Locate the water heat switch on your home’s central circuit breaker panel, which should be located near the water heater. Make sure that this switch is in the “Off” position. This will interrupt the flow of electricity to the device, allowing you to open it without worry of getting electrocuted
- Do not attempt to make any changes to your water heating system until you have double checked that the power has been turned off. Depending on whether your water heater’s circuit breaker is clearly labeled, it may be essential to use a multimeter to check for a live current. Zero volts is what you’re searching for in this case. Keep in mind to label the appropriate breaker after you’re finished.
- 2 Remove the access panel from the unit’s side by pulling it out. Identify the two screws at the top and bottom of the panel and loosen them with a flat-bladed screwdriver to complete the process. Pull the panel away from the body of the device and place it somewhere safe and convenient for you. Take cautious not to loose any of the screws.
- Secondly, remove the access panel from the unit’s side. 3) Recognize the two screws that are located at the top and bottom of the panel and loosen them with a flat-blade screwdriver. Extricate the panel from the unit’s body and place it somewhere safe and convenient. Remember not to loose the screws
- Else, your project might be ruined.
- 3 Remove or push the insulation that is covering the thermostat to the side. An additional layer of insulation is installed within the water heater. If it’s a single piece of styrofoam or similar material, you’ll be able to just lift it out with your hands. Using your hands, move fiberglass insulation out of the way so that you can get to the thermostat controls
- It is necessary to insulate a water heater in order to prevent heat loss and guarantee that measurements are more accurate.
- 4 To adjust the temperature, use a flat-blade screwdriver to raise or reduce the setting. The temperature ranges for the high- and low-ends of the temperature scale will be displayed at the bottom of the thermostat. To adjust the temperature, insert the tip of a screwdriver into the colored adjustment screw and turn it clockwise. When you twist it to the left (counterclockwise), the temperature will decrease, and when you twist it to the right (clockwise), the temperature will raise.
- The adjustable screws on contemporary electric water heaters are equipped with indicator hands that inform you roughly how hot the current setting has been set to. Attend to where your palm settles, since this will help you to fine-tune the temperature of the water even more accurately
- In the event that your water heater has two heating elements, make certain that both thermostats are set to the identical temperature so that one isn’t required to perform more effort than the other.
- 5Replace the insulation as well as the access door. When you’re pleased with the new temperature setting, return everything to the way it was when you first started. Make certain that the insulation completely covers the internal thermostat before reinstalling both protective covers and tightening the screws to fasten them. 6 Restore electricity to the water heater if it has been disconnected. Return to your main breaker panel and turn on the water heater by turning the switch to the “On” position. Please refrain from making any additional adjustments beyond this point since the electricity will be back up and running.
- The flowing water temperature may not reach its maximum temperature for up to an hour after your unit has been turned off for a lengthy period of time
- This is normal.
- After having your unit turned off for a lengthy period of time, it may take up to an hour for your flowing water to reach its maximum temperature.
- After your unit has been turned off for a lengthy period of time, it may take up to an hour for your flowing water to reach its maximum temperature.
- Cooking thermometer: Place a cooking thermometer in the boiling water. Prepare your thermometer in advance so that you may put it in as soon as the container is completely full. After making certain that the probe is completely immersed, let 30-60 seconds for it to determine the temperature
- Make a note of the number you get for future reference. It may assist you in determining the optimal temperature range for your house, as well as identify any heating problems outside of the unit itself. If you don’t put the thermometer in the water straight soon, the water may have a chance to cool down sufficiently to cause your reading to be inaccurate.
- 3 Determine whether or not the water is sufficiently hot. You may be confident that your water heater is operating at peak performance if the temperature is at or near 120 degrees Fahrenheit (49 degrees Celsius). If the temperature is any lower than that, it may need to be raised a few degrees. Keep in mind that temperatures surpassing 120 °F (49 °C) will be too hot for the majority of people in their homes.
- 3) Check to see if the water temperature is sufficient. It is safe to assume that your water heater is operating properly if the temperature is at or near 120 degrees Fahrenheit (49 degrees Celsius). If the temperature is any lower than that, it may be necessary to raise it a few degrees to maintain the desired temperature. Please keep in mind that temperatures over 120 degrees Fahrenheit (49 degrees Celsius) will be too hot for the majority of people in their homes
- 4 Wait three hours before checking the water temperature again. It will take some time for your water heater to adjust to the new temperature setting, so please be patient until it reaches the required temperature. Hold wait on taking a bath or turning on any appliances in case the water being circulated is hotter than you anticipated
- In the meanwhile
- 4 To check the water temperature again, wait three hours. Because it will take some time for your water heater to adjust to the new temperature setting, you will need to be patient until it reaches the desired temperature. In the meanwhile, refrain from taking a bath or using any electrical appliances in case the water being circulated is hotter than you planned.

Not many people are aware that selecting the proper water heater settings may result in substantial savings. 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. 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
Temperature settings on water heaters in Phoenix are frequently set to as high as 140 degrees Fahrenheit as the usual setting. That is far greater than the majority of individuals require, although manufacturers do so for a variety of reasons. The Department of Energy states that germs cannot thrive in water that is so hot, among other reasons. 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.
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 the potential to cause aging hotwater heaters to stop functioning.
How To Adjust Your Gas and Electric Hot Water Heater Temperature Settings
You may save up to 10% on your water heater cost by lowering the temperature by 20 degrees Fahrenheit on your gas or electric water heater, as a general rule of thumb. What you have there isn’t too awful. After all is said and done, the money accumulates quickly, and you can almost certainly think of countless better ways to put it to work. Perhaps you’re thinking to yourself, “But wait.” Showering in hot water is a favorite pastime of mine. However, you almost probably do not take showers above 140 degrees Fahrenheit, which can cause scorching because of the high heat.
No matter what happens, increasing the temperature is simple.
Step One: Get An Accurate Temperature Reading
As a general guideline, every 20 degrees you reduce the temperature of your gas or electric water heater, you may save as much as ten percent on your utility bill. That isn’t too shabby after all! In reality, it builds up over time, and you can almost certainly think of countless better ways to put that money to use. “But hold on a minute,” you might be thinking. “I enjoy taking hot baths!” However, you very probably do not take showers at 140 degrees Fahrenheit, which is truly a searing temperature.
Even if you do, increasing the temperature is a simple process.
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.
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
It is nearly guaranteed that a temperature setting of 150 degrees will be too hot for your water heater. The likelihood of experiencing scalding is quite high at that temperature. You should be concerned about your youngsters, who may experiment with the temperature settings on the faucets while completely unconscious of the risk and end up scorching themselves.
What Is The Maximum Temperature For A Water Heater?
Your water heater will almost likely overheat if you set the temperature to 150 degrees or above. You will almost certainly endure scorching at that temperature. You should be concerned about your youngsters, who may experiment with the temperature settings on the faucet without realizing they are in danger and end up scorching themselves.
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.
Adjusting the Temperature on Your Electric Water Heater
To make a change to the temperature of your electric water heater, you don’t need to have a high degree of technical knowledge or specialized equipment. This is a quick and simple at-home remedy that just takes a few minutes, and you probably already have all of the supplies you need on hand. Fortunately, the process is fairly consistent across the brands of electric water heaters that you are most likely to own, with only a couple of minor differences depending on the manufacturer’s design choices; the overall size of your water heater has no bearing on how you must proceed through our simple steps!
Remove Cover Plates
- The thermostats are located on the front side of your unit, behind two cover panels that must be removed in order to obtain access to them. This may be accomplished by using a Phillips screwdriver or a 1″ nut driver to remove the screws (think “righty tighty, lefty loosey” when doing so)
Remove Excess Materials
- Many eclectic water heaters, particularly newer versions, have additional insulation that will need to be removed before they can be used. Simply remove the excess material and store it in a secure location. Additionally, you will discover a plastic safety plate that can be simply detached or twisted upwards to reveal your thermostat temperature settings
Locate Temperature Dials
- It will be necessary to remove the insulation that has been added to many eclectic water heaters, particularly newer types. Simply remove the excess material and store it in a secure location. Additionally, you will discover a plastic safety plate that can be simply removed or twisted upwards to show the temperature settings for the thermostats
Adjust Your Dials Accordingly
- Everything is now complete except for the actual adjustment of your electric water heater. You’ll need to set both of your thermostats to the same temperature in order to get the ideal temperature. Simply use a flat head screwdriver to make the necessary adjustments to the dials. Be mindful of the fact that it doesn’t take much to make your water hotter
- Ensure that you’re testing these modifications to ensure that your water is at a safe temperature before you reverse the procedures and put everything back to way it was before, as well as replacing the front panel covers. Keep in mind that it will take some time for the water heater to acclimate to the new settings, so be patient. You’re now an expert when it comes to adjusting the temperature of your home’s electric water heater in a matter of minutes.
Bonus Step: Add a Few Extra Gallons of Hot Water
- There is a simple plumber’s method you may try at home to see if you can get a few additional gallons of hot water out of your water heater without breaking the bank. All you have to do is adjust the temperature dial on your bottom thermostat to be slightly higher than the temperature dial on your top thermostat. Here’s why this tiny trick could be useful to you: Water enters your electric water heater through a dip tube that extends from the top of the unit to the bottom of the unit. The hot water that comes out of your water heater leaves via the tank’s opening at the top. Your water heater does not use both heating elements at the same time because there is just insufficient electricity being supplied to the water heater. Due to the fact that the water exits the tank from the top, the top element takes precedence in heating the water that is leaving the tank first. After the top of the water heater reaches the desired temperature, the power is shifted to the bottom of the water heater, which begins to heat the water that is being fed in. Adjusting your thermostats to these settings allows the element at the bottom of the tank to operate for a longer period of time and delivers hotter water up the tank, extending the amount of time it takes before the top of the heater cools down sufficiently to allow power to be transferred back to it. It is possible that this approach will result in a few additional gallons of hot water.

What Is The BEST Water Heater Temperature Setting?
Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. If you have already set the temperature and are thinking to yourself, “I don’t have any hot water,” or “I don’t have enough hot water,” there are a few variables that might be causing the problem. If all else fails, it’s possible that the heating element is faulty and has to be replaced.
How To Check Your Water Heater Temperature
The majority of water heaters do not have a temperature gauge with a digital readout on them. Temperatures or heating ranges are marked on thethermostat, rather than numbers. A cup and a culinary thermometer will be required in order to correctly determine the temperature of the hot water heater. If you haven’t used your water heater in at least one hour, turn on the faucet that is nearest to it. Allow the water to run for at least one minute to ensure that the water is at its warmest possible temperature before filling the cup with it.
Recommended Temperature Settings
Water heaters are pre-programmed to operate at OSHA-recommended temperatures, which are around 140 degrees. The Environmental Protection Agency, on the other hand, recommends lowering the thermostat down to 120 degrees Fahrenheit to save power use and using a booster heater to attain sanitizing temperatures at certain outlets. Another point of view is that lower temperatures are preferable for homes with little children, although higher temperatures are more effective in cleaning and sanitizing surfaces.
However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.
How To Turn Up Your Water Heater
If you are dissatisfied with the suggested temperature of your hot water heater, you may alter the settings to receive extra hot water. Although electric water heaters may require a screwdriver and potentially a tiny wrench or socket, most hot water heater settings are straightforward to modify. Keep in mind that the thermostat is factory configured to a recommended temperature, and that altering the setting may increase the risk of significant burns from the appliance.
How to Set Temperature on a Gas Water Heater
The temperature of a gas water heater may be adjusted by turning the setting knob on the water heater. The majority of gas control valves have a knob with different designations on them, such as A-B-C. Control valves for gas water heaters may be labeled differently depending on the manufacturer. In the majority of circumstances, the following is what each label indicates:
- Warm = 80-90°
- Low = 80-90°
- Hot (or triangle symbol) = 120°
- A= 130°
- B= 140°
- C= 150°
- Very Hot = 160°
- High = 120°
There is a “Vacation” setting that appears from time to time. This does not heat the water, but it does ensure that the pilot light remains lit.
How to Set Temperature on an Electric Water Heater
Turn off the circuit breaker if necessary. Remove the access panels from the room. Under the insulation, look for the thermostat adjustment screwhole.
Adjust the thermostat control to the appropriate temperature by using a straight screwdriver to make the adjustment. After replacing the insulation and panels, the power should be restored. Here’s a good video that demonstrates the procedure:
Factors That Affect Water Temperature
Some of the things that may influence the temperature of your hot water include the distance between the water heater and the outlet, the way the pipes are built, and the quality of the heating element itself, among others. Because of the length of the pipe and the small bore size, it will take longer for the hot water to reach the opening. Additionally, pipes that run beneath or outside the residence may be exposed to freezing or freezing temperatures in the winter and summer. Installing a hot water recirculation system in a large house may be worth considering since it can reduce the amount of time it takes to heat water in all of the property’s outlets while also resulting in significant cost savings over the long term.
If you don’t notice a difference in the water temperature after adjusting the thermostat, it’s likely that the thermostat is broken and has to be replaced.
How to change the temperature on a water heater
- It is possible that you will feel the need to adjust the temperature of your water heater at some point. Changing the temperature of your water heater is a straightforward process, regardless of whether it is standard or tankless. Manufacturers of water heaters recommend that you set the temperature of your water heater to 120 degrees in order to conserve energy and avoid scorching water. Before attempting to adjust the temperature of your water heater, it is always a good idea to consult your water heater’s operation handbook and follow the manufacturer’s recommendations. If you no longer have access to your manufacturer’s operation handbook, you can use the general principles listed below to get by. Water Heater with a Traditional Gas Burner The temperature of your gas water heater may be easily adjusted if you have one. To use the gas control valve, just turn the dial on the front of the valve. The hot setting will be around 150 degrees, while the mild setting will be approximately 95 degrees. As previously stated, the optimal temperature setting is 120 degrees. Electric Water Heater in the Old Fashioned Style Turn off the circuit breaker for the water heater. Remove both the top and bottom access panels from a two element water heater if you have one. The bottom panel on single-element water heaters should be removed. As soon as you get the access panel open, pull the insulation to the side or remove it completely so that the thermostat can be seen. If the plastic cover does not have an access hole for the adjustment screw, it should be removed. In most cases, the thermostat adjustment screw is situated at the bottom of the thermostat, immediately above the element. To make any adjustments, you’ll need a little flat blade screwdriver with a flat blade. Replace the plastic cover when you’ve done changing it to your preferred temperature (if you removed it). Replacing the insulation above the thermostat and heating element is simple. Replace the access panels and re-connect the power cords as needed. Tankless water heaters are a type of water heater that does not require a tank. In most cases, adjusting a tankless water heater is as simple as pressing a button on your front panel command center or remote control, depending on the make and type of your water heater.

What temperature is right for your water here?
When it comes to conserving energy at home, one of the first things that comes to mind is most likely changing the thermostat settings on your home heating system to the lowest possible level. Nevertheless, what about the temperature control device on your water heating system? The factory default setting on most water heaters supplied today is 140 degrees, and sometimes even higher – a temperature that is high enough to induce scorching but not high enough to meet the needs of most people (there are exceptions to this, however, as we will see).
However, the most compelling reason to lower your water temperature is to save electricity (and, consequently, money).
When you adjust your water heater’s thermostat to 120 degrees Fahrenheit rather than 140 degrees Fahrenheit, you’ll save around $50 per year in standing heat loss and more than $400 per year in fuel use.
A 140° setting is right in certain circumstances
However, while the majority of individuals can get by with a 120-degree setting, there are some situations in which a 140-degree setting is more appropriate. For example, if you have a member of your family who has a compromised immune system or chronic respiratory condition, a 140-degree setting is suggested to avoid Legionnaires’ disease and other water-borne illnesses. Additionally, if your dishwasher does not pre-heat the water, you may want to keep the temperature at a higher setting.

What Temperature Should a Hot Water Heater be Set At?
What temperature should a hot water heater be set to in order to provide hot water? Despite the fact that you may not think about your water heater very often, it is an important component of your home’s plumbing system. It is possible that a faulty water heater will result in increased electricity bills as well as water that is either blazing hot or freezing cold. It is vital to schedule annual maintenance in order to ensure that your unit is clean (hard water build-up is detrimental to your water heater) and that the temperature is set appropriately on the thermostat.
Manufacturers and the Department of Energy hold diametrically opposed perspectives.
The majority of experts feel that any temperature below 120 degrees Fahrenheit increases the likelihood of bacteria, such as legionella, which causes Legionnaire’s disease, developing within your water heater as a result of stagnant water in your water heater.
Optimal Water Heater Temperature
It is important to remember that the kind of pipe, how the water is heated (gas or electric), and whether your system is a tank or tankless all have no effect on the temperature. A variety of variables must be taken into account when determining an appropriate temperature, including:
- Keep the temperature at 120°F if you have little children and/or the elderly in your home, who are susceptible to third-degree burns in seconds, or if you live alone, because you will have less need for hot water. 140 degrees Fahrenheit should be considered if your home contains an immunocompromised individual, a dishwasher that does not pre-heat, or a large number of people due to a greater need for hot water.
The question is, what is the cost of energy? We recognize your frustration! On average, water heaters account for 14-18 percent of a home’s total energy use. Furthermore, it may be tempting to turn the thermostat down in order to save money on energy costs. It’s worth mentioning that reducing the temperature by 10°F results in a 3-5 percent reduction in energy use. Legionella, on the other hand, is capable of surviving at temperatures as high as 122 degrees Fahrenheit. So be sure to strike a balance between your risk tolerance and your energy consumption objectives!
- A temperature dial is a feature that is typically found on water heaters.
- Start with 120°F and progressively raise the temperature until it is to your satisfaction.
- The installation of a water tank booster may be an appropriate option in families where the necessity to maintain a higher hot water temperature for health safety must be balanced against the danger of scorching.
- Instead, you can live in a place where hot water takes a long time to reach the faucet, no matter what degree you set it at (or a certain tap farthest from the hot water heater).
A hot water circulating system circulates hot water gently through the pipes so that you don’t have to wait for it. No matter which option you pick, we are merely a phone call away if you are suffering hot water problems!
Check the Temperature of Your Water Heater
Then there’s the question of energy costs. Please accept our apologies. On average, water heaters consume 14-18 percent of the energy consumed by a residence. Furthermore, it may be tempting to turn the thermostat down in order to save money on heating and cooling. Note that reducing the temperature by 10°F results in a 3-5 percent reduction in energy use. When it comes to Legionella, the bacteria may survive at temperatures of up to 122oF. So, make a trade-off between your risk tolerance and your energy consumption goals!
When it comes to hot water heaters, a temperature dial is a regular sight.
Start with 120 degrees Fahrenheit and progressively raise the temperature until you reach your desired level of comfort.

Water Heater Life Expectancy
The bulk of hot water heaters are expected to last between 8 and 12 years, according to predictions. The replacement of your water heater should be your first choice if your unit is 10 years old or older and seems to be leaking or not performing correctly. Repairing your water heater may only provide a temporary solution to your problem.
Water Heater Maintenance
As with any piece of equipment, a little care and maintenance may go a long way toward extending the life of your water heater and keeping it in good working order. If you want to ensure that your water heater is in good working condition, you should consider contacting a professional to do the necessary maintenance. Always double-check that the temperature of your hot water heater is adjusted to the suitable levels. This will prevent any bacteria from growing in the cold water and will protect you from being scalded by a shower that is much hotter than you anticipated.
