Summary of Setting the Temperature of Your Tankless Water Heater
Occasionally, clients contact us because their tankless water heater is constantly cycling on and off. When we walk outside, we notice that the water heater is set to an excessively high temperature most of time. As a result, many individuals turn the heat up as high as they possibly can, reaching temperatures over 140 degrees. If you have a tankless water heater, that water heater has a flow switch, and you must have a significant amount of water flowing through that water heater for that water heater to activate.
For starters, if you have the water heater set to 140 degrees, you are mixing much too much cold water with far too little hot water in order to keep the temperature at the shower head comfortable.
- It is possible to resolve this issue by turning down the temperature of the water heater.
- As long as you maintain the temperature about 130 degrees, you won’t have to worry about becoming too hot when taking a shower.
- The temperature is too high for your home at 140 degrees.
- You’ll be generating enough flow to turn on that tankless water heater and keep it running during your shower session.
- After less than an hour, they were at my house to have a check at my hot water heater.
- He went out of his way to make sure I had hot water to keep me going till the parts came.

Tankless Water Heater Temperature Setting – Things To Consider
Upon installation of a water heating equipment on your property, the temperature is set to 140 degrees Fahrenheit as a default setting. It is possible to get burnt if you take a bath with only warm water while the temperature is this high. Toddlers and the elderly are at a very high risk of suffering severe burns. Children’s skin is particularly sensitive, and elderly people’s reflexes may take a long time to recognize that the water is excessively hot. As a result, you may be asking why the tankless water heater temperature control has been set to an excessively high setting.
Bacterial Accumulation Prevention
Bacteria tend to congregate in warm, stagnant water, although it can also accumulate in cold water on occasion. However, it is most commonly seen growing in water that is between 41 and 135 degrees Fahrenheit in temperature. The temperature setting of 140 degrees Fahrenheit is somewhat higher than the risk zone limit of 130 degrees Fahrenheit. As a result, producers regulate the temperature to avoid bacterial development. Despite this, some specialists believe that a temperature of 120 degrees Fahrenheit is safe for the majority of people.
A pre-set water temperature is included with the newer units, and they also have an anti-scaling technology that delivers water to the tap at 120 degrees Fahrenheit.
In electric tankless water heaters, legionella bacteria accumulates in the machine’s bottom and has the potential to cause a type of pneumonia in those who are exposed. It is spread in the air by inhaling filthy water droplets when bathing or taking a shower.
When companies offer you a tankless gas water heater, their first aim is to ensure that you are completely satisfied. The fact that you have energy and water bills does not worry them. They want you to be completely happy when you turn on the water faucet and receive properly warm water from the faucet. In the event that you receive just lukewarm water, the vast majority of you will conclude that the device is incapable of heating water and that your hard-earned money has been spent. The temperature of a tankless water heater may be adjusted to provide hot water with no effort.
However, it has a significant impact on sales psychology.
Nonetheless, investing in a high-quality heater will prove to be useful in the long run.
Customer satisfaction is the number one objective of the companies that provide tankless gas water heaters. They are unconcerned about your power expenses or water use. Their goal is for you to be completely happy when you turn on the water faucet and receive properly warm water from it. In the event that you only receive lukewarm water, the vast majority of you will conclude that the device is incapable of heating water and that your hard-earned money has been spent. You only need to change the temperature of your tankless water heater to obtain hot water.
The impact on sales psychology, on the other hand, is significant.
Nevertheless, investing in a high-quality heater will be helpful to you in the long run.
Frequent Hot Showers
If you have a large family who takes many showers at the same time, a 20-degree temperature difference might have a significant impact on the amount of hot water available. If you take regular hot showers in your home, the 120 degrees Fahrenheit tankless water heater temperature setting is the best choice for you.
Do you have a dishwasher that is more than a decade old? Many earlier versions do not have an advanced heater, and as a result, they will not be able to wash the utensils correctly with a tankless water heater temperature change of less than 140 degrees Fahrenheit.
Kids And Elders In The House
The water temperature should be set at 120 degrees F in homes with small children and elderly residents to reduce the danger of burning or scorching at the water fixture.

What’s The Best Water Heater Temperature Setting?
A hot shower may receive a bad name from your dermatologist since it might dry up your skin, but many people like it for its relaxing properties! In a household where hot water is fiercely competed for among family members, or even between your washing machine and dishwasher, you may be tempted to raise the temperature of your hot water heater. But at what point does it become too hot? There are differences of opinion between the Department of Energy and the industry. Scalding can occur at temperatures below 120 degrees Fahrenheit, although 140 degrees Fahrenheit is the normal default temperature.
Whatever temperature setting you choose, it’s vital to remember that the kind of pipe used, how the water is heated (gas or electric), and whether your system is tanked or tankless have no effect on the temperature you choose.
There are, however, a number of elements to take into consideration when determining your thermostat setting:
- Use 120°F if you have small children or the elderly in your house who are prone to third-degree burns in seconds, or if you are the sole inhabitant of your home since there is less demand for hot water. Consider 140°F if you have an immunocompromised individual in your house, a dishwasher that does not pre-heat, or if you have a large number of occupants owing to the increased need for hot water.
But what about the expenses of energy? We get what you’re saying! Water heaters account for around 14-18 percent of the total energy consumed by a residence on a typical day. Furthermore, it may be tempting to lower the temperature in order to save money. It should be noted that a 10°F decrease in temperature is related with a 3-5 percent reduction in energy use. Legionella, on the other hand, can live at temperatures as high as 122°F. So make sure to strike a balance between your risk tolerance and your energy consumption targets!
- Many hot water heaters are equipped with a temperature control dial.
- Start with 120°F and gradually increase the temperature in small increments until you get your desired result.
- A water tank booster may be an appropriate option in houses where the requirement to maintain a greater hot water temperature for health safety must be balanced with the need to reduce the danger of scorching.
- Alternatively, you could live in a house where, no matter what temperature you select, hot water takes an inordinate amount of time to reach the faucet (or a certain tap farthest from the hot water heater).
- Whatever you choose, we’re only a phone call away if you’re having issues with your hot water!

Ideal Water Heater Temperature Settings: Tank & Tankless
Even though you may not give your water heater much thought on a regular basis, it is an extremely important part of your home’s plumbing system and should not be overlooked. Although most people set their water heater temperature between 130 and 140 degrees Fahrenheit, according to Consumer Product Safety Commission guidelines, reducing your water heater temperature to 120 degrees Fahrenheit can save you money and avoid scorching. Keeping the temperature of your water heater lower will save you a lot of energy and money while also extending the life of the heater.
What Is Normal Water Heater Temperature?
Manufacturers of water heaters are not required to specify a specified operating temperature for their devices. Some businesses adhere to the Consumer Product Safety Commission’s advice that their heaters be set at 120 degrees. However, data indicates that at least 41% of water heaters operate at or above this temperature. Some families are quite content with it. Others, on the other hand, may be at risk for second-degree burns as a result of this. Your water heater’s working temperature typically varies between 120 and 140 degrees Fahrenheit, as we’ve already established.
Water heaters that have a temperature indicator are available on the market.
Choose a more exact temperature measurement to be on the safe side.
Allow the water to flow at a variety of settings for a certain amount of time. Choose the temperature setting that is most comfortable for you. However, for reasons of safety, the temperature should be set at 120 degrees Fahrenheit at all times.
What Temperature Should Your Water Tanks Be Set At?
It is recommended that you set the temperature of your water heater between 120 and 140 degrees Fahrenheit. If you drop the temperature of your water any further, you run the danger of polluting your water source with bacteria. If the temperature rises beyond 140 degrees, you run the danger of causing serious burns in your house. Temperatures of 120 degrees Fahrenheit are generally suggested for water heaters. Although you should not adjust your thermostat to this degree right away, you should consider doing so.
You should do the following steps before setting or altering the temperature of your water heater, as we’ll outline below:
Measure the Current Temperature
Before you can alter or set your temperature, you must first know the temperature of the water that is flowing out of the faucet or sink. You can accurately test the temperature of your water with a conventional kitchen thermometer, which is inexpensive. Start by turning on the hot water tap located near your water heater, which should be the first step in this process. Collect water in a container and use a thermometer to determine the temperature of the water. Keep the thermometer in place until the temperature readings on the thermometer stop climbing.
The thermostat should be adjusted to reduce temperatures if they become excessively hot.
Access the Thermostat
First, turn off the water heater’s power source before making any modifications to the water heater. Electric heaters are often configured with two thermostats and two heating components, which is standard practice. As a result, you’ll need to get access to the thermostats and make adjustments. Set the thermostat to the same temperature as the furnace for optimal operation. The access panels should be removed with a flat-head screwdriver or a Philips screwdriver. Remove the screws holding the panel in place in order to reveal the thermostat.
It is possible that you may need to remove insulation in order to see your thermostat clearly.
Test the Water temperature
Before making any adjustments to the water heater, consider taking some measurements of the present temperatures. Take a jar of hot water and use a kitchen thermometer to determine the temperature of the water. It will provide you with the ability to determine its current temperature. After that, you may proceed to make the necessary changes to the heater. Using a cooking thermometer, confirm that the temperature has been reached at the appropriate level. If it has, everything is in working order.
Water Heater Temperature and Saving Energy
Check the present temperatures before making any adjustments to the water heater. Using a culinary thermometer, place hot water in a container and record the temperature reading.
In order to know its current temperature, you must use this tool. Next, proceed to make any necessary modifications to your heater. Using a cooking thermometer, confirm that the temperature has been reached at the appropriate level. If it does, everything is in working order.
Set The Temperature to 120° F
As we’ve seen, unless you have persistent respiratory issues or a compromised immune system, 50 degrees Celsius (120 degrees Fahrenheit) is a comfortable temperature. It is not necessary to raise the temperature of your water heater any further. Setting your thermostat to 120 degrees Fahrenheit will assist you in conserving electricity. Whenever you decrease your thermostat by 10 degrees Fahrenheit, you will save between 3-5 percent on your energy bills.
Select An Energy Efficient Appliance
Water heaters are built in a variety of ways. When shopping for a water heater, never choose for the cheapest one available. The lower-priced alternative may save you money in the short term, but it may cost you more in the long run due to increased energy use. Always choose for models that are Energy Star certified and have energy factors between 0.67 and 0.7. These models are energy-efficient, and you will save a significant amount of money on your energy bills.
Use Cold Water
Each type of water heater has its own design. A cheaper water heater should never be chosen when purchasing a water heater. The lower-priced alternative may save you money in the short term, but it may cost you more in the long run because of increased energy use. Consistently choose for models that are Energy Star certified and have energy factors of 0.67 to 0.7. As a result of their energy-efficiency, these models can help you save a lot of money on your energy bills.
How to Adjust the Water Heater Temperature On Your Unit
There are at least five different types of water heaters available on the market. Let’s go over them one by one in terms of lowering your energy bills. We’ll also go through how you can adjust the temperature of the heaters, which includes:
Storage tank Water Heaters
The majority of them are classic heaters, which heat only as much water as the tank can comfortably contain at a time. Due to the insulation, the tanks will remain warm until water is required. If you need more hot water than the tank can hold, you’ll have to wait until the tank refills. It takes around 1 to 2 hours for the water in the tank to heat up once more. These heaters are among the most popular and least expensive alternatives available. They can, however, be made more energy efficient if you use a timer to operate them.
In order to alter the temperature on the tank water heaters, follow the instructions outlined below:
- First and foremost, switch off your heating. Remove the bottom and top coverings from the table. Using a flat screwdriver, make minor adjustments to the thermostat. Replace the covers with new ones. After that, you can re-energize the system.
Tankless Water Heater
The first thing you should do is turn off the heating. Remove the covers from the bottom and top. Using a flat screwdriver, make adjustments to the thermostat. Covers should be replaced. After that, you can re-energize the system;
Heat Pump Heaters
Heat pumps use the heat from the ground and the air to raise the temperature of the water in their reservoirs. Heat pump heaters, like all other types of heaters, utilize electricity to transport heat rather than to create it.
There is also a tank that has to be cleaned on a regular basis. Heat pumps are well-known for their energy-saving capabilities, which may result in savings of up to 60% on energy costs. However, they require a significant amount of room for installation and are prohibitively expensive to purchase.
Solar Powered Water Heaters
These heaters heat water by harnessing the force of the sun. If you want to get the most out of your solar panels, you should install them on your roof. When used in warm climates and on sunny days, the water heaters are useful. During the rainy season, make sure you have a backup water heater ready. Solar-powered heaters are environmentally friendly. However, unless you receive a subsidy from the government, the expense of installing them is prohibitively expensive. They are equipped with a control panel that allows you to simply alter the temperatures.
Condensing Water Heaters
These water heaters heat water by utilizing the power of the sun. For optimal performance, you should install a solar panel on your roof. During warm weather and on bright days, solar water heaters are most effective. During the rainy season, make sure you have a backup water heater. Solar-powered heaters are extremely energy-efficient appliances. But unless you are fortunate enough to be awarded a government subsidy, the expense of installing these systems is prohibitively expensive. Their design includes a control panel that allows you to effortlessly modify the temperatures.
Does Turning Up Your Water Heater Make Hot Water Last Longer?
Increasing the temperature of your water heater is one option for dealing with the problem. The technique taken here is to utilize less hot water while the temperature of the water is still high. The likelihood is that you have ever been in a warm or hot shower that suddenly become ice cold is considerable. It is a negative sensation, regardless of whether it is part of your bedtime ritual or your morning wake-up call. The issue here is that your hot water isn’t staying hot for very long. To accomplish this, increase the temperature of your thermostat that is attached to your hot water tank.
Considerations When Selecting a Water Heater Temperature Setting
A number of factors must be taken into account when determining the appropriate temperature setting for your water heater. The following are some questions that you must be able to respond to:
Are There At-Risk People Living In Your Home?
It is possible that persons who are sensitive to high temperatures will be badly harmed if the water is really hot. For example, it would take only two seconds of exposure to hot water at 150 degrees Fahrenheit for a tiny baby to suffer third-degree burns. If a newborn is exposed to 140 degrees for only 5 seconds, the same degree of burns is also feasible. Lowering the temperature is, therefore, not only safer for your kid, but it is also more cost-effective for you. If you have a newborn in your home, we recommend that you keep your heater temps at 130 degrees or above.
They should likewise adhere to the same rules and principles as everyone else.
Temperatures of around 140 degrees are recommended for such adults, given that there are no children present in the home.
Do You Own Energy-Efficient Appliances?
It is possible for persons who are sensitive to high temperatures to be gravely harmed if the water is really hot. A small baby would only require two seconds of exposure to hot water at 150 degrees Fahrenheit to suffer third-degree burns, as an example. An infant who is exposed to 140 degrees for only 5 seconds can likewise sustain the same level of burns.’ Because of this, lowering the temperature is better for your infant as well as for your energy bills in the long run. Keeping the temperature of your heater at 130 degrees is recommended if you have a baby in your home.
Likewise, they must abide by the same regulations and principles as well.
Provided there are no children around, we propose temperatures of approximately 140 degrees for such individuals.
How Many People Stay In Your House?
Especially when it comes to taking a shower, everyone has a favorite temperature for their water heating system. With the help of the cold and hot water knobs, you can effortlessly adjust the temperature to your liking. If you want a hotter shower, increase the hot-to-cold water ratio in your shower. A lower ratio indicates a colder shower experience. The temperature of the water flowing from the water heater, on the other hand, has an impact on the results as well. Because hotter water comes from the heater, you will require less hot water and more cold water in order to get the desired temperature.
It also implies that if you set the water temperature to a lower setting, you will run out of hot water more rapidly.
Smaller dwellings with fewer occupants are able to operate at lower thermostat settings.
Health and Safety Considerations
When you purchase and install a water heater in your house, the temperature should be adjusted to 120 degrees Fahrenheit. It is the factory-set temperature for the product in this configuration. Take a shower with the water flowing at this temperature and you’ll most certainly get burnt and scalded, according to the experts. As we’ve seen, the elderly and children are the most vulnerable groups when it comes to burns. However, there are still valid reasons why the temperatures are maintained at such elevated levels:
Preventing Bacterial Growth
Water that is stagnant and lukewarm is ideal for the growth of bacteria. The danger zone is between 105 and 135 degrees centigrade, despite the fact that certain germs flourish in either hot or cold temperatures. Sulfur or a “rotten egg” odor in your hot water is frequently the result of this phenomenon. Whenever the anode begins to degrade excessively, germs might begin to proliferate within the water heater. A high-capacity anode rod can assist to reduce bacteria growth and keep your hot water clean.
As a result, this temperature is considered safe for preventing the formation of microorganisms. 140 degrees, on the other hand, is dangerously hot for youngsters and the elderly, and can result in scorching injuries.
When a manufacturer offers a water heater, they are primarily concerned about the customer’s pleasure with the product. They are less concerned with water conservation and energy conservation than they are with making us pleased with the items. If the water coming from the heater is only somewhat warm, a client may be led to believe that the heater is not functioning properly. Many consumers are happy that the heater is performing satisfactorily since they can get hot water from the faucet. As a result, manufacturers elevate these temperatures for marketing purposes in order to give the impression that their goods are extremely effective.
As we’ve shown, determining the optimal temperature for your water heater is simple if you follow the proper procedures. Selecting the optimal temperature setting will result in lower energy expenses as well as a longer service life for the heater. The optimal water heater temperature ranges between 120 degrees and 140 degrees Fahrenheit, and you should set your equipment to this range. Nevertheless, there are a few things to bear in mind when determining the optimal water heater temperature setting.
There is a good chance that you will have sufficient instant hot water in your home.

What Temperature Should You Set Your Hot Water Heater?
The fact that the daily temps have fallen down into the “need to put on some socks and a sweater” level also means that I’ve been increasing the warmth of my morning showers and post-workout baths into the steamy-hot triple digits. It can be difficult to distinguish between “ahh” hot and “o scorching, and the line can be separated by the smallest of eyelash width modifications. However, aside from the pleasures of soaking in a hot bath or taking a long, hot shower, the temperature at which you set your water heater may have an unanticipated and subtle impact on your health.
Unwanted visitors that you may be bringing onto your skin, into your dishwashing machine, and through your faucet are possible.
According to the World Health Organization, there is a relationship between temperature and how it impacts potential microorganisms within residential water heating systems. There are two major and diametrically opposed risks:
- If the temperature is too high, users will be scalded. If you keep the temperature too low, you run the danger of infections, notably Legionella, which can cause legionellosis (Legionnaires’ illness).
Prevention of Legionellosis from the World Health Organization
- Legionella kills nearly rapidly when temperatures above 70 degrees Celsius (158 degrees Fahrenheit). At 60 degrees Celsius (140 degrees Fahrenheit), 90 percent of the bacteria die in 2 minutes. At 50 degrees Celsius (122 degrees Fahrenheit), 90 percent of the bacteria die in 80–124 minutes, depending on the strain. At 48 to 50 degrees Celsius (118 to 122 degrees Fahrenheit), they may live but not reproduce
- Temperatures ranging from 32 to 42 degrees Celsius (90 to 108 degrees Fahrenheit) are ideal for development.
Although some manufacturers recommend that water heater thermostats be set at 140 degrees Fahrenheit, most homes only require them to be set at 120 degrees Fahrenheit, which also helps to reduce mineral accumulation and corrosion in your water heater and pipe system. Water heated to 140 degrees Fahrenheit also offers a safety threat, since it can cause scorching. Increasing the temperature of your water heater results in two types of savings: lower standby losses (heat lost from the water heater into the surrounding basement area) and reduced usage (from water demand or use in your home).
So what’s the ideal temperature then?
The Consumer Product Safety Commission (CPSC) believes that a temperature of 120 degrees Fahrenheit (49 degrees Celsius) provides the best balance between safety and comfort. It is advised that you bathe in accordance with the following guidelines, whether you set the temperature higher or lower than recommended by the Canada Safety Council:
- Never leave a child alone in a bathtub while the water is being drawn, and always check the water temperature before placing your child in the tub
- Before taking a bath or shower, check the temperature of the water. Initially, turn on the cold water, then gradually add hot water until the desired temperature is reached. Teach youngsters to switch on the cold water first and then turn off the hot water before doing anything else.

What Temperature Should a Hot Water Heater Be Set At?
Previous PostNext PostYour water heater accounts for around 18 percent of the energy consumed by your house. If the temperature of your water heater is set too high, you will be forced to pay the price in your monthly energy bill. The converse is true: if you have your water heater set too low, your water may not get hot enough (resulting in short showers), or worse, it may get contaminated with germs. Maintain a 120-degree temperature for your water heater at all times because infections can form in the stagnant water within the water heater, notably Legionella, which is extremely deadly.
In addition to being hot enough to keep viruses at away while not being scorching hot enough to cause blistering, 120 degrees will provide adequate hot water for most small households while still being relatively energy-efficient, according to the Environmental Protection Agency.
Factors That Affect Hot Water Temperature Setting
These criteria are unaffected by the kind of piping you have (PEX, PVC, or copper), the method of heating the water (gas or electric), or even if you have a tankless hot water heater installed.
- Owners of dishwashers that do not pre-heat the water may wish to set their water heater temperature to 140 degrees
- Elderly or families with young children may want to keep the temperature at 120 degrees. BabyCenter.com states that “it takes just two seconds for a kid to acquire third-degree burns from water that is 150 degrees and five seconds if the water is 140 degrees, the temperatures at which hot water heaters frequently leave the manufacturer.” It is recommended that the hot water temperature be maintained at 140 degrees in homes with people who have a compromised immune system or respiratory problems. Because there is less demand for hot water and hence less money spent on hot water, many people who live alone prefer a lower temperature within an acceptable range. The temperature of the water tank is often set higher in big households, in order to support the increased demand for hot water
- Nevertheless, if you want to save money, every 10 degrees you lower the temperature of the water tank thermometer, you save 3 to 5 percent on your energy bill.
Are you still undecided? To begin, set the temperature to 120 degrees Fahrenheit and gradually raise it in small increments until you reach the desired shower temperature.
What’s Your Current Temperature Setting?
Check the temperature setting on the water heater (if one is available) or take a temperature reading from the faucet to determine what it is currently.
After turning on the hot water faucet, allow it to run for a few minutes before getting the temperature reading.
Solutions to Common Hot Water Tank Problems
If you’re concerned about pathogens in your hot water, as well as the possibility of scalding water, you might consider installing a hot water tank booster. This allows you to maintain your water at 140 degrees in the tank while mixing it with cold water to bring the temperature down to 120 degrees before it reaches the faucet. Having a hot water circulating system installed in your home might alleviate the problem of waiting for hot water to reach the faucet in a large household. This method circulates hot water slowly through the pipes in order to prevent it from cooling down before it reaches the faucet.

Risks Of Too High Or Too Low Water Heater Temperature
You might be wondering what temperature to put your water heater to. When you purchase a water heater unit, the temperature is typically set by the manufacturer. However, this does not rule out the possibility of having some control over its temperature. The good news is that you may set the temperature to a level that is comfortable for you while yet ensuring the safety of your family. Previous to this, we wrote an article in which we spoke about how the heat in your shower might suddenly vary.
The temperature of the device is important since it can have an impact on how well it performs.
Top Risks of setting your unit temperature too high
An skilled plumber would advise against raising the temperature of your unit over the recommended level since it might endanger the safety of your children. It can also have an impact on your utility costs and the heater itself. In order to assist you, we have listed the following risks:
1. Scalding Accidents
Setting the temperature too high might result in scorching mishaps that result in burn injuries. According to the findings of a study on water heater temperature and attributes, many water heaters are frequently set at dangerously high temperatures. Several studies by the Centers for Disease Control and Prevention (CDC) have discovered that scald burns are the most common cause of injury in younger children. Every day, over 300 children between the ages of 0 and 19 are treated in emergency departments for burn-related injuries, with two of these children dying as a result of their injuries.
In order to avoid tap burns, experts strongly recommend that you have your water heater inspected. Accidents such as this may be prevented by allowing your water to flow for three minutes and then monitoring the temperature with a candy thermometer thereafter.
2. High electricity bill
Warning: Using a water heater with the temperature set too high will cause your energy cost to rise! According to the Department of Energy, standby heat losses from your water heater can cost you anywhere from $36 to $61 per year in energy savings. The good news is that by lowering your thermostat, you may save anywhere from 4 percent to 22 percent on your annual energy expenditure. Lowering the temperature of your water heater can help to decrease standby heat loss, which is one of the reasons you have a high energy cost.
3. Lowers your unit’s service life
According to some sources, hot water can accelerate the accumulation of hard water mineral silt, particularly calcium carbonate, in the tank’s interior. It is possible that the buildup would cause corrosion in the water heater tank, which will result in a reduction in the estimated lifespan of the complete device. Leaks and polluted water might occur as a result of the rust accumulation in the storage tank. Another major reason for water heater failure is the deposit of rust on the interior of the heater.
We wrote an essay about why it’s important and how you can extend its lifespan.
Risk of setting your unit temperature too low
If you want to save money on energy costs, you should avoid setting the temperature of your unit too low. It is possible that you will have a health problem as a result.
1. Legionnaires disease
Every year, around 100 people in the United States are sent to hospitals due to a form of bacterial illness that can be caused by water heaters. The infections connected with the bacterium were responsible for up to 12 percent of the country’s death rates. Specifically, the Legionella bacteria are responsible for this particular kind of atypical pneumonia. It is common to find this bacterium in water at low temperatures — often between 20 and 45 degrees Celsius. You can contract the disease if you inhale small water droplets in the air that contain germs that cause it.
Evidence indicates that the majority of the bacteria’s spread occurred through the provision of drinking water in private residences.
It has been shown that the danger of contamination is significantly reduced when water heaters are set at 60°C or 140°F.
Ideal Temperature For Your Water Heater
The optimum temperature is. What several agencies have to say about the optimal temperature is summarized below: According to the Occupational Safety and Health Administration (OSHA) and the World Health Organization (WHO), water heaters kept below 60 degrees Celsius (140 degrees Fahrenheit) may promote Legionella development. This temperature, on the other hand, will almost certainly increase the likelihood of being burned by searing hot water. If you have young children at home, the Centers for Disease Control and Prevention (CDC) and the Energy Department recommend that you set your water heater’s thermostat to 120°F or lower.
To do this, set your thermostat to a steady temperature. This will help you keep control over the water temperature throughout your home, preventing it from being overly hot.
So, is it 120°F or 140°F?
We recommend keeping the temperature between 120 and 140 degrees Fahrenheit. However, you may regulate the temperature of your water heater between 130 and 140 degrees Fahrenheit, which is very useful for large water heaters used in hospitals and industrial settings. In case you have little children at home, set the temperature to 120°F, which is considered safe by the majority of the population.
