How to Turn Up a Hot Water Heater
Article in PDF format Article in PDF format When bathing, cleaning dishes, or doing tasks around the house, cold water may be a major hassle. Increasing the temperature of your water heater may be necessary if you are experiencing regularly colder water temps. While adjusting a gas or electric water heater takes deft hands and a thorough grasp of the components, it is usually a straightforward procedure. As long as you use safety when working with your water heater, you should be able to alter the temperature quite fast and easily.
- 1 Before adjusting the gas water heater, make sure all other open flames are extinguished. It is not recommended that you come into direct touch with natural gas
- Yet, it is better to be cautious than sorry in this situation. Please refrain from lighting candles, smoking, or using any other open flames in the house while you are adjusting your water heater.
- When modifying the water temperature, there is no need to switch off the gas.
- 2Find the dial on the front of the water heater and turn it to the desired temperature. The gas control valve is located here. It is often a black or red knob with two sides: one for warm and another for hot. In certain circumstances, it may additionally feature notches on the side to distinguish between the different temperature settings. Advertisement
- s3 Rotate the dial from the warm to the hot position to activate the feature. Do not turn the dial all the way to the hot setting. To begin, shift it slightly toward the hot side of the spectrum from where it was previously. Your hand may be burned if the water temperature is increased to its maximum setting (hot). You may always adjust the temperature to be much hotter later on if necessary
- 4 Once you’ve waited three hours, check the water temperature. Wait at least 3 hours before checking the water temperature again to ensure that it has had enough time to warm up. If the water temperature remains too low or the water seems too chilly, the gas control valve should be adjusted once again.
- To avoid major burns, do not raise the temperature over 120 degrees Fahrenheit (49 degrees Celsius).
- 1 Disconnect the circuit breakers for the water heater. Locate the circuit board in your property, which is usually located in the electrical box. You should be able to turn off two circuit breakers because most water heaters require around 240 Volts of energy. See whether there are any details on the location sheet on the inside of the panel—if there are none, switch off all of the panels to be on the safe side.
- Never make any adjustments to your electric water heater without first turning off the circuit breakers. If you’re not sure how to switch off the breakers, call an electrician for help to avoid electrocution.
- 2 Remove the access panels from the heater. The access panel(s) should be in the shape of rectangular boxes and should be located on the front of the water heater. Depending on whether the water panel has a single or double access panel, pry open one or both of them to get access to the panel’s internal controls.
- The majority of panels can be accessed without the need of a screwdriver. It should be sufficient to use your hands
- 3 Take off the insulation to see the thermostat location. You should be able to detect a small layer of insulation between the thermostat and the door access panels. To obtain a better look at the thermostat, take remove all of the insulation and adjust the temperature as needed.
- Keep the insulation somewhere safe since it will need to be reinserted into the water heater in order for the thermostat temperature to remain precise.
- 4 Raise the temperature on the thermostat by one degree. The majority of thermostats are controlled by a screw in the centre. Insert a flat-tipped screwdriver into the screw and raise it several notches with the screwdriver. To avoid burns, keep the thermostat set no higher than 120 degrees Fahrenheit (49 degrees Celsius).
- The thermostat should display temperatures ranging from around 90 degrees Fahrenheit (32 degrees Celsius) to 150 degrees Fahrenheit (66 degrees Celsius), with a maximum temperature of 120 degrees Fahrenheit (49 degrees Celsius) being ideal. Even though there are two panels, there should only be a single thermostat on each of them. The number of panels has more to do with the design of the water heater, as both panels should be connected to the same thermostat
- The thermostat should display temperatures ranging from around 90 degrees Fahrenheit (32 degrees Celsius) to 150 degrees Fahrenheit (66 degrees Celsius), with a maximum temperature of 120 degrees Fahrenheit (49 degrees Celsius) being preferred. Even though there are two panels, only one thermostat should be used. The number of panels has more to do with the design of the water heater, as both panels should be controlled by the same thermostat.
- 1Bring the heated water to a boil for 3 to 5 minutes. Select the sink that is closest to your hot water heater and let it run for at least 3 minutes before cleaning it. Any water that comes out of the sink during the first several minutes will have already been absorbed by the plumbing system. It is necessary to allow for sufficient clearing before testing the water heater in order to obtain an accurate reading
- 2To check the temperature of the water, use a candy or a kitchen thermometer. Place the water in a dish or cup and take the temperature of the water right away. Allow at least 20-30 seconds for the thermometer to be submerged in water to obtain a dependable reading. 3 Make a note of the temperature number. As a result, while cold water is an issue, it is equally important not to have your water temperature too high. If the temperature rises beyond 120 degrees Fahrenheit (49 degrees Celsius), you run the danger of suffering burns. For an understanding of the link between temperature and the length of time it will take to cause major burns, consider the following numbers:
- 120 degrees Fahrenheit (49 degrees Celsius): 5+ minutes
- 125 degrees Fahrenheit (52 degrees Celsius): 60-120 seconds
- 130 degrees Fahrenheit (54 degrees Celsius): 5-30 seconds
- 140 degrees Fahrenheit (60 degrees Celsius): 1-5 seconds
- 150 degrees Fahrenheit (66 degrees Celsius): 1-1 1/2 seconds
- 160 degrees Fahrenheit (71 degrees Celsius) or above: Immediately
- 4If necessary, repeat the check in approximately 3 hours. If the temperature is too low or too high, make the necessary adjustments to the water heater and check the temperature again after 3 hours. It will take some time for the water heater to adjust its internal temperature and warm or chill the water to the proper degree. Advertisement

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. Currently playing: Keep an eye out for this: Take a look inside the CNET Guide to Smart Living. 1:00
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.
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.

How to Turn Up Water Heater
The likelihood that the previous tenants turned down the water heater before leaving your holiday home or new house is high whether you’re staying on vacation or moving into a new property. As a cost-cutting measure, it is sound. However, in order to do so, you must understand how to modify the temperature of the water heater to fit your requirements. You’re in luck because we’ll walk you through the procedure right here.
We must first determine the type of gasoline with which we are working before proceeding. The technique for installing an electric water heater differs from the procedure for installing a natural gas water heater. Anything exceeding 120 degrees Fahrenheit is considered hazardous, and we do not suggest it in any circumstances.
When the temperature reaches 130 degrees, you can suffer serious burns in as little as 5 seconds. Gas is simple to switch on; electricity, on the other hand, is a little more complicated, so we’ll start there:
How to Adjust Temperature on Electric Hot Water Heater
- Turn off the electricity at the breaker—because most water heaters work on 240v, you’ll probably need to flick two switches to do this. Don’t let yourself be electrocuted! In the event that you are unsure which switches control the water heater, turn them all off. The access panel and insulation should be removed since you can have a tank with two access panels. In order to modify the temperature, you must first remove the panel(s) and any insulation. Adjust the temperature by rotating the dial using a flat-head screwdriver (in certain situations, you won’t need one) to increase the heat. If your thermometer has notches marked with temperature measurements, you may set it to the temperature you choose. It’s as simple as replacing the insulation and panel(s) and you’re done! So please be patient as the water will take a couple of hours to warm up to the new temperature
How to Turn Up a Gas Water Heater
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
What About Tankless?
If you have an on-demand water heater, it should be as simple as pressing a button that is easily accessible or adjusting a dial to the desired temperature. If you are encountering any difficulties, examine the instruction booklet provided by the manufacturer.

How to Turn Up Your Water Heater
When you turn on a hot water faucet, you expect to be greeted with hot water. But what happens if the temperature of your hot water isn’t up to your standards? It’s possible that increasing the temperature of your water heater will solve the problem. Even if the temperature of a water heater is preset at the manufacture, you may like the water to be either warmer or colder than the factory setting. You may control the temperature of your water heater regardless of whether it is powered by electricity or gas.
This article will demonstrate how to adjust the temperature, as well as discuss several important safety issues that should never be disregarded.
Water Temperature Safety
When adjusting the temperature of your water heater, there are several really severe safety considerations to keep in mind. For a variety of reasons, the Environmental Protection Agency advises that you set your water heater temperature to 120°F: Water at 120°F will do three things: first, it will conserve energy and minimize your electricity cost; second, it will be hot enough to prevent the majority of infections; and third, it will not be hot enough to cause a burning injury. However, 120°F is not hot enough to kill the Legionella bacterium, which is responsible for the outbreak of Legionnaires disease.
- When Legionella bacterium is exposed to 140 degrees Fahrenheit water for 32 minutes, it is destroyed.
- Although it is not possible to have the best of both worlds, or more particularly the best of both temps, there is a workaround.
- This will guarantee that your hot water is not only disease-free, but it will also prevent scorching accidents from occurring.
- When the hot water reaches the faucet, the temperature has dropped to 120 degrees Fahrenheit.
- Speaking with a specialist will also assist you in determining the best course of action for your particular case.
Why a Water Heater Runs Cold
There might be a multitude of reasons for your water heater to be operating at a low temperature. If the temperature of your water is substantially lower than expected, or if you have no hot water at all, this article might assist you in troubleshooting the cause of the issue. It’s possible that the problem is a simple remedy, such as changing a heating element, or that the demand for hot water in your home has risen and your water heater is unable to keep up with the demand. We recommend that you solve these difficulties first since, in the majority of situations, addressing the fundamental cause of the problem is always the most effective solution.
It is possible to increase the temperature of your water heater if you just want a scalding hot shower and your water heater isn’t giving it.

Pros and Cons of Turning Up the Temperature on Your Water Heater
There might be a multitude of reasons for your water heater to be operating at a lower temperature. Whether your water temperature is substantially lower than expected, or if you have no hot water at all, the information in this article can assist you in troubleshooting the situation. It’s possible that the problem is a simple remedy, such as changing a heating element, or that the demand for hot water in your home has risen and your water heater is unable to keep up. We recommend that you tackle these issues first since, in most situations, addressing the underlying cause of the problem is the most effective solution.
Most significantly, increasing the temperature of your water heater will provide the impression to your family that they have more hot water available. It is called a feeling since the volume of heated water produced by your heater is the same regardless of the model you have. What makes a difference is that when water is generated at a higher temperature, most people instinctively believe they require less water. This is advantageous since it might give your family the impression that they can take hotter showers or wash their dishes at a higher temperature.
Aside from that, if you have a gas heater, you may easily lower its temperature to the lowest level if you are leaving on vacation.
However, lowering the temperature of your water heater below this limit will have no effect on these appliances because they pre-heat the water.
Increases in the temperature of your water have two significant drawbacks to consider. The first is the rise in your energy bill that you will notice. An increase in temperature indicates that more energy is required to heat the water, which results in an increase in utility expenses. The other point of worry, as previously said, is safety. Take cautious not to overheat your water heater by turning it to the maximum setting. Calcification is a serious threat to little children and elderly people alike, and it can occur at temperatures as low as 110°F.
Heating the house to temperatures over the recommended 120 degrees Fahrenheit might be extremely hazardous. Also to consider is the potential risk of Legionnaires’ disease and other bacteria growth in your hot water tank and piping if the water is too cold.
How to Check Your Water Heater’s Temperature
It is extremely simple to check the temperature of the water heater. Here’s how it’s done:
- Start by turning on the hot water at the faucet that is nearest to your water heater
- Allow the hot water to run for a few minutes before using it. Fill a cup halfway with hot water, then place a culinary thermometer into the cup to check the temperature. Food thermometers are affordable, and if you don’t already have one, you may get one from Amazon. Observe and take note of the temperature
How to Turn Up the Temperature on a Water Heater
The method you regulate the temperature of your water is mostly determined by the sort of water heater you have. There are three types: tankless, electric tank-style, and gas tank-style. Tankless is the most common. In addition, there may be some differences across manufacturers, but they are often located in close proximity to one another. Check your heater’s owner’s handbook for any specifics that are special to it.
Heater temperature adjustments are found on the digital control panel of the vast majority of tankless water heaters (both gas and electric). Many people even monitor the temperature of the air they are sending out, which makes the change that more simpler. The temperature may be raised or decreased in most cases by using the same method as you would to set the thermostat on an air conditioner.
Electric Water Heaters
The vast majority of electric water heaters are equipped with an upper and lower temperature thermostat. A set of thermostats is concealed behind two panels on the heater’s tank. Both thermostats will need to be set to the same temperature in order to function properly. Here’s what you should do:
- Circuit breakers should be used to turn off your water heater. Remove the covers from the two access panels by using a screwdriver to pry them off. One is positioned towards the top of the tank, while the other is located near the bottom. Using caution, carefully remove insulation in order to locate the thermostat. To make a little adjustment to the thermostat, locate the dial and use your screwdriver to gently turn it in the direction of either hotter or colder, depending on your preferences. Both thermostats should be set to the same temperature. Due to the fact that each manufacturer labels them differently, yours may only indicate “hotter” and “colder,” but as long as you move each by the same amount, you should be OK
- Replace the insulation and access panels, and then re-energize the water heater by resetting the circuit breaker on the water heater. Allow at least 3-hours for the water heater to cool before monitoring the temperature again. If necessary, repeat the procedure.
Watch the Video
Gas water heaters are more convenient to use since they often feature a dial that is simple to see and is positioned outside the tank. Here’s what you should do:
- Once you’ve located the dial, all you have to do is turn it to the left or right depending on whether you want to make the temperature warmer or cooler. Before monitoring the temperature of your hot water, give it at least 3 hours to warm up. Make any necessary modifications.

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.
- 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.
The less you have to think about your hot water heater, as is the case with most other household utilities, the better. The only thing that is actually vital to know is that it is operating to provide your house with the hot water that it requires. Nonetheless, having a basic understanding of how your water heater operates is always important. If the machine is one that is utilized on a regular basis, this is especially true.
Water heaters are responsible for ensuring that water is delivered via the pipes to its intended destination at the right temperature every time you shower, wash dishes, or do a load of laundry. So, how exactly does a hot water heater function in your household setting?
Hot Water Heater Components
First, we’ll take a look at the many components that work together to provide you with the hot water you require. With the exception of a few minor variations, these components are shared by both electric and gas water heaters. It is possible that this will provide an answer to your inquiry about “how does a hot water heater work?”
The vast majority of water heaters seen in houses throughout the United States have enormous, insulated tanks that hold hot water. These water heater tanks are available in a variety of sizes, commonly ranging from 20 to 80 gallons in capacity. The size of the tank should be proportional to the number of people who will be using hot water in the home, and the normal household tank has a capacity of 40-60 gallons of water.
The dip tube is the point at which cold water from your home’s municipal water supply, well, or other water source is introduced into the tank for storage. It is right before the water heater that your main water line separates. Water is pumped from the main valve to your cold water faucet through a cold water service line when you switch on the cold water faucet. The water that comes out of the hot water tap is channeled via the dip tube and into the hot water storage tank. This occurs prior to the water traveling through the hot water service line to the house.
The cold water enters via this opening and is subsequently heated by the water at the bottom of the tank.
Heating Element / Gas Burner
A heating element in the tank of an electric water heater heats the water within the tank to a desired temperature. When using a gas water heater, the heating mechanism is provided by a gas burner. Both of these items may be found near the bottom of the tank.
Another safety step is the use of anode rods. It does this by electrolyzing the tank and preventing rust from forming. In this case, the metal-coated steel rod (which is often coated in aluminum, zinc, or magnesium) rusts instead of the steel lining that is used to line the tank’s internal walls.
Water heaters are equipped with a thermostat on the outside that allows you to monitor and change the temperature of the water being heated.
The hot water service line is the pipe that transports hot water from the tank to the hot water service line. It may be found at the very top. The hottest water rises to the top of the tank due to the fact that hot water has less density than cold water (and heat rises by its own nature).
- Valve for Drainage– The drain valve is positioned near the bottom of the tank, on the exterior of the tank. The drain valve, as its name implies, is responsible for draining off silt that has accumulated inside the tank. Shut-off Valve– A shut-off valve is located on the outside of the water heater. Essentially, this stops the flow of water into the tank. Pressure Relief Valve– The water inside the tank is extremely pressured, necessitating the use of a pressure relief valve. An emergency pressure relief valve is designed to prevent pressure from accumulating to a dangerous level.
How Does a Hot Water Heater Work?
So, how do all of these components interact with one another? What is the operation of a hot water heater? So, here’s a synopsis of the situation. The trip of your hot water begins with the main water pipe and continues to your shower, washing machine, sink, dishwasher, and other appliances. Water heaters that use gas or electricity are both tank-type water heaters.
These are the most prevalent types of water heaters that may be used in residential settings. They both function substantially on the same premise, with the primary differences being in their different heat sources. Regardless of the heating technique used, the following procedure must be followed.
Here’s how a water heater works:
In order for water to enter your home, it must flow via the main water line. Just before the water heater, the line is divided into two different paths, each of which serves as the water intake system for your home. After that, you switch on the hot water faucet. Ice-cold water pours through the shut-off valve and into the water heater tank, where it will soon be heated to a comfortable temperature. The water is heated by the heating mechanism located at the bottom of the tank in accordance with the thermostat setting.
After that, you switched on the hot water faucet, and additional water poured into your hot water tank through the dip tube.
This hot water rises via the heat-out pipe and is sent to the hot water faucet.
Tankless Water Heaters
A tankless water heater is another alternative that is becoming increasingly popular, albeit being less prevalent. Tankless water heaters do not store hot water in a tank that is constantly heated; instead, they heat water only when it is required. When you turn on a hot water faucet, a flow sensor in the tankless water heater unit is triggered to respond. Assuming the tankless unit is fueled by gas, this sensor switches on an internal fan to pull in air, opens the gas valve, and ignites the burner by activating a gas valve inside the tankless unit.
- In either scenario, the heat exchanger inside the unit is warmed, and the water is heated to a certain temperature as a result of this heating.
- As a result, there is no need to store hot water in a tank and there is no need to use the energy required to maintain a high temperature on a consistent basis.
- With a tankless unit, you will never run out of hot water since there is no tank to run out of water.
- These advantages, on the other hand, come at a larger cost up front than with a traditional hot water heater, which is why they are more expensive.

How to Set Your Water Heater to Vacation Mode and Turn It Back
Water heating systems consume a significant amount of energy to run. As a result, an increasing number of environmentally aware people (as well as those who just want to cut their utility bills) are learning how to set their water heaters into “vacation mode” with the goal of conserving energy and saving money.
So, what exactly is vacation mode, and where do you go to locate it on your computer or smartphone?
Water Heater Vacation Mode: What Is It?
In your water heater system, there is an option called vacation mode that allows you to run your boiler at lower temperatures than usual, therefore conserving energy. In most cases, manufacturers set vacation mode at 50° F, which is far lower than the temperature required to heat your house, but high enough to keep any water from freezing while you’re gone. Certain systems will not require you to make any changes to the manufacturer’s settings. It is possible to regulate the temperature of the water by turning a dial.
Where Do You Find Vacation Mode And How Do You Use It?
There are a variety of techniques available from water heater manufacturers for putting your unit into vacation mode, the most prominent of which is a particular setting on the thermostat itself. To check if your thermostat has a vacation mode, go to the settings menu and scroll through the options. If it does, all you have to do is choose it, and the system will take care of the rest. If your thermostat does not have a vacation mode that is expressly stated on it, you may manually accomplish the same result as a vacation mode by setting the temperature to “Pilot” mode and leaving it there until you return.
Why You Should Put Your Water Heater In Vacation Mode
It is primarily for financial reasons that you should put your water heater into vacation mode. You have no need to heat water to 120 degrees if you are not going to be in the house to utilize it. It is a waste of energy that results in an increase in your utility costs. The other reason is to keep freezing water from causing damage to your pipes during lengthy periods of extremely cold weather. If you forget to switch off your water heating system while you’re gone and the water freezes into ice, you face the danger of cracks in your pipes, damage to your plumbing, and perhaps the need to replace your entire system.
Then, when you switch your system back on, it doesn’t work anymore, and you frequently end up with flooding in your house as a result of this failure.
In order to avoid substantial harm to your system, a compromise must be made between utilizing no electricity at all and using a little amount of heat to keep it running.
Even if your thermostat doesn’t have a dedicated vacation mode, you can still lower the temperature to keep your house safe while you’re gone on vacation.
Adjusting Your Water Heater Settings: How To Maximize Efficiency
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.
No matter what happens, raising the temperature is a simple process.
How To Adjust Your Gas and Electric Hot Water Heater Temperature Settings
Now that you understand why you should reduce the temperature of your water heater, let’s look at how to go about doing so.
Step One: Get An Accurate Temperature Reading
It’s likely that the thermostat dial linked to your water heater tank is not functioning properly. As a result, you should really use a thermometer to monitor the temperature of the water flowing out of your faucet. The Department of Energy suggests that you measure the amount of water that is flowing out of the faucet that is the furthest away from your water heating system. Make a note of the settings after you’ve found them.
Step Two: Figure Out Where to Make the Adjustment
There are several distinct types of water heaters, and we’ll go through each of them separately.
Electric Water Heater Settings
In the case of an electric water heater, you must modify the hot water settings at the top and bottom of the unit. Both controls, which are often concealed behind a panel and consist of knobs that you crank to establish the appropriate electric water heater thermostat settings, are typically located on the same side of the panel.
Gas Water Heater Settings
Newer gas water heaters are equipped with temperature controls that are similar to those described above in the section on electric water heaters. Most gas heaters, especially older models, feature a temperature knob near the base that may be easily adjusted to the appropriate temperature.
Tankless Water Heater Settings
Finally, tankless water heaters are available. This is likely the simplest modification to make because most thermostats include an LED screen that allows you to directly control the thermostat’s temperature.
In addition to being convenient, these systems frequently allow you to modify the tankless water heater settings more accurately than you could with traditional dial-based adjustment methods.
Step Three: Make The Adjustments
If you have an electric unit, make sure to turn off the electricity to it before modifying the hot water heater settings at the top and bottom, as we previously discussed in detail. This may be accomplished simply turning off the necessary settings on your circuit breaker panel. Doing so is also recommended in the case of a gas water heater that consumes some power (as some newer units do). But hold on a minute! What temperature should you choose as a starting point? The Department of Energy suggests that you set your heater to 120 degrees Fahrenheit for the best performance.
Some water heater temperature controls now include buttons that read “A-B-C” instead of numbers, which makes them easier to use.
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?
The highest temperature setting for the majority of water heaters is 150 degrees Fahrenheit.
Is 140 Too Hot For A Water Heater?
Yes, temperatures above 140 degrees Fahrenheit are uncomfortable for the majority of people. The only exception would be persons who require an additional layer of protection against germs, which cannot thrive in water at that temperature. However, because such a state does not protect you from scorching, you will almost certainly need to install an equipment at the showerhead that cools the water before it is discharged from the showerhead.
Why Is My Water So Hot?
If you haven’t changed the settings on your hot water heater in a long time, they are most likely still set to the factory default of 140 degrees.
