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.

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.
Tankless
The process of adjusting a tankless water heater is quite similar to the process of adjusting your air conditioning thermostat. Adjust the temperature by using the digital control panel, which may be adjusted up or down as desired.
Gas or electric water heaters
Some gas water heaters include a dial towards the bottom of the device that may be adjusted simply by turning it – no tools are required for this operation. Nonetheless, most current tank water heaters (whether gas or electric) require a bit more effort, but the process is still straightforward and should only take a few minutes.
- Turning off the water heater’s electricity at the circuit breaker is the first step. To remove a thermostat(s), locate the access panel for the thermostat(s) and remove it using a screwdriver
- Remove the insulation by peeling it back. To adjust the thermostat, use a flathead screwdriver to turn it up or down.
- If your water heater has two thermostats, make sure they are both set to the same temperature. The temperature on the top thermostat should be a few degrees higher than on the bottom thermostat.
- Replace the insulation and re-install the access panel, if necessary. Reconnect the water heater’s power supply
- It is possible that you may need to relight the pilot light on a gas water heater.
Once you’ve made the necessary adjustments, you should wait at least three hours before checking the water temperature once more. It is possible that you may need to make more modifications in order to get the desired temperature. If you’ve increased the temperature and are still getting chilly showers, it’s possible that your hot water heater has to be serviced or completely replaced.

- 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.

- Some versions may have a second plastic cover behind the metal access panel, which can be difficult to see. With a little tug, you should be able to gently remove it.
- 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.

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.
- Make sure your water heater is off by turning off the electricity. This may be accomplished by locating your circuit breaker and shutting off the electricity in the area surrounding your water heater
- Then, locate the thermostat(s) on your water heater and turn them on. Typically, they are located behind a control panel that is secured with screws. Remove the cover from the access panel using your screwdriver (s). To access the thermostat, you may need to remove the insulation from your heater if it is properly insulated. The thermostats will be controlled by a dial, and the dials will have a varying reading depending on the manufacturer of the heater. Once the control panel has been removed, you may change the temperature knobs to make the room hotter or colder according on your preferences in terms of temperature. Take care to set both thermostats to the same temperature setting if you have more than one. Replace the control panel covers and the screws with your screwdriver after they have been removed. After that, re-energize your water heater’s electrical system. After many hours, check the temperature of your hot water (about three to four). Continue to follow the above instructions until the water temperature reaches the required setting
- If it still does not, repeat them until the temperature reaches the ideal setting for your needs.
Other Considerations: Water Heater Thermostat Setting Safety
Shut down the water heater’s electric circuit. Finding your circuit breaker and shutting off the electricity in the area surrounding your water heater are two ways to do this. Find the thermostat(s) on your water heater and set them to the appropriate temperature. A control panel that is screwed to the wall usually houses these components. Remove the access panel lid using a screwdriver by pressing down on it (s). To access the thermostat, you may have to remove the insulation from your heater if it is insulated.
Once the control panel has been removed, you may alter the temperature knobs to make the room hotter or colder according on your preferences in terms of temperatures.

- 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
- Congratulations on having made it this far! Not only are you more capable than you anticipated, but you’re also practically finished! The dial should now be visible
- This is what regulates the temperature settings on your thermostats, which will make the time spent in the tub when the weather cools down that much more enjoyable. Don’t forget about how we indicated that some design options may differ based on the manufacturer? Now is the time when you’ll notice the following differences: The settings on some dials are alphabetical, while others are numerical
- There are even dials that vary from “hot” to “extremely hot,” such as the dials we are altering in our movie
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.

You may experiment with a simple plumber’s tip at home to see if you can squeeze a few more gallons of hot water out of your water heater. Nothing more than setting the temperature dial on your bottom thermostat slightly higher than the temperature dial on your top thermostat will do the trick! Why this simple hack can be beneficial to you is as follows. Water enters your electric water heater through a dip tube that extends from the top of the unit to the bottom of the unit’s base. It is through the top of the tank that hot water from your water heater is expelled from it.
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.
Making these modifications to your thermostats allows the element at the bottom of the tank to operate for a longer amount of time and delivers hotter water up the tank, so extending the time it takes for the top of the heater to cool down sufficiently to transfer power back to the top element.
A few more litres of hot water may be used throughout this procedure.

Testing the Thermostats on a Dual Element Water Heater
Because the majority of electric water heaters employ both an upper and a bottom element, the procedure outlined below is intended for these models only. A multimeter and a screwdriver will be required for this test. You can get an excellent, affordable multimeter online or at your local hardware shop for less than $20. Putting the UPPER thermostat through its paces:
- Immediately turn off the water heater’s electricity. Remove the panels that provide access to the elements, as well as the insulation beneath them
- Set the upperthermostat to the highest level possible with a screwdriver. Lower the lowerthermostat to its most conservative setting
- Restart the water heater by turning the power back on. Check the two wires above the reset button to ensure that electricity is being sent to the water heater. The voltage should be shown as 240 volts. Check the power on the upper element terminal screws with your multimeter to ensure they are not faulty. If there is no power, the thermostat is defective and must be replaced. Ensure that the lower thermostat is operational if there is electricity.
Putting the LOWER thermostat through its paces:
- Set the top thermostat to the lowest setting possible. Make sure that the lower thermostat is set to its maximum setting. Check to see whether there is voltage on the bottom component. Assuming the multimeter indicates that there is power at the element, take a few minutes for the water to warm up.
- Turn down the thermostat’s temperature setting and listen for an audible click, which shows that the thermostat is operating properly.
- To determine whether there is power at the element if there is no voltage, check the lower thermostat.
- In order to test the top contact screw, place one of the multimeter probes there and another probe on the metal shell of the water tank. It should display a voltage measurement of about 120 volts. The top thermostat, which supplies voltage to the lower thermostat, will need to be replaced if there is no indication of operation. Place one probe on the lower contact screw of the water tank and the second probe on the metal casing of the water tank if a reading is obtained. It should display around 120 volts. If this is not the case, the lower thermostat will have to be changed.

In order to test the top contact screw, place one of the multimeter probes there and another probe on the metal tank case. This device should display a voltage measurement of around 120 volts. The top thermostat, which supplies voltage to the lower thermostat, will require replacement if there is no reading. Place one probe on the lower contact screw of the water tank and the second probe on the metal casing of the water tank if a reading is received. 120 volts should be displayed on the screen.
Step 2
In order for the thermostat to sense the internal water temperature, it must be secured in place by means of a particular bracket that clamps down on it tightly against the tank wall. Remove one side of the bracket by gently prying it out while twisting the other side of the thermostat upwards to prevent the bracket from locking back into place. Repeat the process on the opposite side. On dual element versions, repeat the process with the lower thermostat.
Step 3
In order for the thermostat to sense the interior water temperature, it must be secured in place by means of a particular bracket that fits snugly around the tank. Remove one side of the bracket by gently prying it out while turning that side of the thermostat upwards. This will prevent the bracket from locking back into place after being removed. Repeat the process on the other side of your body. On dual element thermostats, repeat the process for the lowest thermostat setting.
Step 4
If the bracket was broken during the removal of the thermostat, you can purchase a replacement bracket at the same time.
When the old bracket is removed, the new one should be placed flat against the tank and dragged downward until it is securely in place.
Step 5
Replacement brackets are available if the bracket was destroyed during the thermostat removal process. The old bracket can be wrenched upward to remove it, and the new one may be put flat against the tank and slid downward until it is securely in place.

If you have already fixed 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 things you should consider. If everything else fails, it’s possible that the heating element is faulty and has to be repaired or replaced altogether.
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.

Caution to anyone who is adjusting the temperature of their water heater! Scalding is extremely dangerous, and raising the temperature of your water can raise your chances of getting scalded by as much as 50%. In the event that you are at all concerned about your capacity to accomplish this project safely, you should check with your plumber before proceeding. In addition, please keep in mind that those with reduced skin integrity, such as youngsters, the elderly, and the disabled, can be scalded by water as cold as 110°F.
Check the Current Temperature First
If you are experiencing problems with your hot water coming out too hot or not hot enough, understanding how to regulate your water heater may be quite useful. Ideally, you should check the temperature of your hot water at the faucet before making any changes to the present settings so that you can determine how much to modify the heater. It is quite acceptable to use almost any basic cooking thermometer for this purpose. If you want to calibrate your thermometer, place it in a cup of cold water and hold it there until the temperature dial reaches 32 degrees (or stops at the lowest degree on the gauge).
- Meanwhile, while the thermometer is calibrating, turn on the hot water tap nearest to the heater and turn it on until it is hot to the touch (but be careful not to burn yourself!).
- The temperature dial will come to a complete halt when the water temperature is reached.
- The procedures indicated below will work for the vast majority of hot water heaters, but not all of them.
- Attention: This “how to” is for tank-style water heaters only; it does not apply to tankless water heaters at this time.
Electric Tank Water Heaters
The majority of electric water heaters will have two thermostats, one on top and one on the bottom, located beneath the two control panels. The two thermostats on your water heater must be adjusted to the same temperature in order for it to operate most effectively and efficiently. Some smaller units may simply have a single thermostat, which is understandable. To complete this task, the following tools will be required: Screwdriver with a Phillips-head or a flat-head Step 1: Disconnect the power supply to the heater.
- Step 2: Locate the thermostats, the majority of which will be hidden behind an access panel.
- Remove them with the proper screwdriver and store them in a secure location to prevent them from being misplaced.
- Some smaller units may simply have a single thermostat, which is understandable.
- There will be a dial on the thermostat, and the dials will have a varied reading depending on the heater manufacturer you are dealing with.
- With your screwdriver, make little adjustments to the dials depending on your requirements and the reason for the adjustment.
- Step 5: Re-attach the screws to the panels and close them up.
Step 6: Turn on the heater’s power supply again. Step 7:After around 3-4 hours, check the temperature of your hot water once more. Follow these procedures again until the temperature is just perfect. If the temperature is still not just right, repeat the process.
Gas Tank Water Heaters
Most gas water heaters will include a simple, easy-to-read dial at the bottom of the tank to control the temperature of the water. The actions outlined above should be followed if your model has a hidden dial beneath an access panel. If this is the case, follow the steps outlined above to change it. To complete this task, the following tools will be required: None! Step 1: Adjust the temperature by turning the knob warmer or colder according to your requirements. Step 2: After roughly 3-4 hours, check the temperature of your hot water once more.
