How To Adjust Temperature On 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

A chilly shower is not something anybody enjoys taking. When you turn on the hot water, it is even worse since you will get scalded. Correctly regulating the temperature on your water heater is critical not only for your health and safety, but also for saving money on your power bill. You may save money and protect your skin by adjusting the temperature of your water heater.

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.

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. Is the energy efficiency of your home high? Here are five different methods to find out. CNET’s Guide to Smart Livingis a one-stop shop for tips, techniques, and how-to guides that can help you live a more intelligent life.

How to Adjust Your Water Heater’s Temperature

It has been shown that even ordinary tap water might be hazardous. Every year, a number of individuals (mainly youngsters) are sent to hospitals after suffering burns as a result of water heaters that have been set excessively high. But what exactly does “too high” imply, and how can people ensure that their water heaters are set at a temperature that will not cause them to be burned, is a mystery. The Environmental Protection Agency (EPA) recommends a hot temperature setting of 120 degrees Fahrenheit for both safety and energy savings reasons.

Use this procedure if the stickers on the water heater do not inform you how to set the temperature and you are unable to locate the owner’s handbook.

  1. However, it turns out that even ordinary tap water might be harmful. Every year, a number of individuals (mainly youngsters) are sent to hospitals after suffering burns as a result of water heaters that have been set at an excessive temperature. Nevertheless, what does “too high” actually imply, and how can homeowners ensure that the temperature of their water heaters is adjusted at a level that will not cause them to burn? The Environmental Protection Agency (EPA) recommends a hot temperature setting of 120 degrees Fahrenheit for both safety and energy efficiency reasons. Because most dials on water heaters are not labeled with numbers, it might be difficult to locate the appropriate setting on the water heater temperature control dial. Use this procedure if the stickers on the water heater do not inform you how to set the temperature and you cannot locate the owner’s manual:

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.

Family Handyman

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).

  1. 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!).
  2. The temperature dial will come to a complete halt when the water temperature is reached.
  3. The procedures indicated below will work for the vast majority of hot water heaters, but not all of them.
  4. 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.

If the temperature is still not just right, repeat the process.

Helpful Water Heater Temperature Tips

  • It is possible to save money on your energy bill by turning down the temperature on your heater. In order to conserve energy and money while you’re away, turn your water heater’s temperature down to its lowest setting before leaving for vacation. It is recommended by the majority of manufacturers that you use a temperature setting of 120 degrees. For the most part, most homes with children will choose a temperature that is just below 120 degrees to avoid the possibility of scorching. A higher water temperature may be preferred by certain individuals, who may be OK with a slightly higher setting
  • Some home equipment (such as dishwashers) require higher temperatures (about 140 degrees) in order to effectively destroy bacteria
  • However, because most modern dishwashers pre-heat the water, reducing the temperature should not have an adverse effect on the device.

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.

  1. 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.

  • s3 Increase the temperature of the water to enjoy warmer water for cleaning and bathing purposes. It is advantageous to have hotter water in your house for a variety of reasons. For starters, it may make taking a shower or soaking in the tub more enjoyable, because you won’t have to worry about running out of hot water as fast as you would otherwise. This method may also be used to increase the performance of appliances that do not utilize warmed water (such as dishwashers and washing machines), which will aid in cleaning filthy things.
  • 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.
  1. Take note that your water will not be as hot, which may have an influence on your comfort or the degree of sanitation for cleaning tasks.
  • 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.
  • 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.
  • Many of the newest electric water heaters have indicator hands on the adjustment screws that tell you roughly how hot the current setting is. Attend to where your hand 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 same temperature so that one is not pushed to perform more work than the other.
  • 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.
  1. 1 Fill a glass halfway with boiling water. Set a timer for one minute and turn on the nearest faucet to the water heater to start the process. Keep a drinking glass or similar container under the stream until you’ve captured a few inches of water
  2. Until the water is as hot as it can possibly be
  • It is preferable to utilize a container that has been kept at room temperature in order to obtain the most accurate reading possible.
  • 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.
  • Increase the temperature of your water by 10 degrees at a time to lessen the chance of burning yourself
  • To lessen the danger of scorching, raise the temperature of your water in 10-degree increments.
  • Make any required modifications before everyone in your home begins their daily routine
  • Otherwise, they will be inconvenienced.

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

  1. 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.

The procedure of installing an electric water heater is pretty simple, provided that you observe basic safety precautions.

Electric Water Heater Recommended Temperature

Before attempting to modify the temperature of an electric water heater, examine the suggested temperature as well as the potential risks of various temperature settings. Water heater settings of 120 degrees Fahrenheit are recommended by the United States Department of Energy for most houses. Water heaters are frequently installed with the temperature set at 140 degrees Fahrenheit. Scalding can result from turning the water too hot when washing your hands or having a shower while using that higher temperature setting.

The danger is especially larger for children who may accidentally turn the faucet all the way to the hot side. By lowering the thermostat setting, you can not only make your home safer, but you can also save money on your energy bill by lowering standby heat loss.

Measure the Current Temperature

Before you make any changes, check to see how hot the water that is already flowing from your faucets is to begin with. A normal cooking thermometer may be used to accurately measure the temperature of the water. Turn on the hot water tap nearest to your water heater, if it is not already running. Collect some of the water in a cup and use your thermometer to determine the temperature of the water. Leave it in the water until the temperature on the thermometer stops rising. If the temperature of the water does not exceed 120 degrees Fahrenheit, you should raise the temperature of the water heater.

  1. Before making any modifications to your water heater, turn off the electricity to the unit for your own protection.
  2. For the greatest results, make sure that all of the thermostats are the same temperature.
  3. Remove the screws that are holding the panel in place so that you can see what’s behind it.
  4. It is possible that you may need to remove insulation in order to see the thermostat.

Adjust the Temperature Setting

Please take care not to touch or move any of the wires within the water heater. To adjust the water temperature, turn the dial in either way, depending on whether you want to raise or lower the temperature. Decide on the direction by referring to the marks on the dial. The dial may be easily adjusted with the use of your screwdriver. Replace the insulation and the panel in their original locations. Using the screws, reattach the panel to the wall.

Test the Water Temperature

Reconnect the electricity to your water heater if it has been disconnected. Allow at least three to four hours for the new temperature setting to be reached before checking it again. Make use of the same procedure you used for your initial temperature check, turning on the hot setting on the faucet nearest to the water heater and collecting water. Using your cooking thermometer, check the internal temperature. If it reaches the temperature you prefer, you’re done for the day. If you want the water to be hotter or cooler, repeat the thermostat adjustment process, wait a few more hours, and then check the temperature of the water once again.

If you need to make modifications in the future for whatever reason, this will assist you in getting back to the desired temperature.

When working with gas appliances, it’s important to remember to always put safety first. It is essential that there are no open flames anywhere around you when you are adjusting the temperature since this will necessitate increasing the gas pressure. Essentially, the procedure is as follows:

  • It is not necessary to switch off the gas in order to adjust the temperature. To begin, locate the control knob, which is most likely labeled with the settings for warm and hot (but it may have other possibilities)
  • You want to be as conservative as possible while making the modification. Don’t just turn it up to the maximum/hottest setting
  • Allow several hours for the tank to heat the water before testing the temperature with a hot water faucet in the house

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.

  1. 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
  2. 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
  3. If it still does not, repeat them until the temperature reaches the ideal setting for your needs.

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.
