How Hot Should Water Heater Be


Water heaters are set to a default temperature of 140 degrees, but is that really necessary? The answer depends on a few factors. If you have young children or elderly people in your home, you’ll want to err on the side of caution and keep the water heater at 140 degrees.

This will help prevent scalding accidents. But if everyone in your home is old enough to be aware of the danger of hot water, you can probably turn the dial down to 120 degrees and save some money on your energy bill.

If you’re wondering how hot your water heater should be, the answer may surprise you. The majority of water heaters are set to around 140 degrees Fahrenheit, but some experts say that’s actually too hot. The reason for this is that water above 120 degrees Fahrenheit can cause serious scalding injuries.

So if you have young children or elderly family members in your home, it’s best to err on the side of caution and keep your water heater set to a lower temperature. Of course, there’s no need to make things uncomfortable – around 115 degrees Fahrenheit should be plenty warm for most people. And if you find yourself needing a little extra warmth, just crank up the hot water tap until it reaches the desired temperature.

What is the Ideal Temperature for Domestic Hot Water?

If you’re like most people, you probably think that there is an ideal temperature for domestic hot water. After all, who doesn’t want their water to be just the right temperature? Unfortunately, the answer to this question is not as simple as it seems.

While there are some general guidelines that can help you get close to the perfect temperature, ultimately it will come down to personal preference. Here’s a look at what you need to know about finding the ideal temperature for your home’s hot water. First and foremost, it’s important to understand that there is no single “ideal” temperature for domestic hot water.

Instead, what is considered ideal will vary depending on individual needs and preferences. With that being said, most experts agree that the optimal range for domestic hot water falls somewhere between 120°F and 140°F. At these temperatures, the water will be hot enough to provide adequate cleansing without causing discomfort or scalding.

Of course, even within this range there is room for variation. For instance, some people prefer their showers on the hotter side while others find lukewarm water more comfortable. Similarly, some households use more hot water than others due to factors such as how many people live there or whether anyone has any medical conditions that require hotter water (e.g., elderly individuals with poor circulation).

As such, it’s important to experiment a bit until you find a temperature that works well for your particular situation. One final note on finding the ideal temperature for your home’s hot water: be sure to keep safety in mind. Water temperatures above 140°F can pose a serious scalding risk so it’s important not to go too high when adjusting your thermostat.

Is 150 Too Hot for Water Heater?

There is no definitive answer to this question as it depends on a number of factors, such as the type and size of your water heater, the climate you live in, and your personal preferences. However, we can provide some general guidelines to help you decide if 150 degrees is too hot for your water heater. If you have a standard electric water heater, the thermostat is usually set to 140 degrees Fahrenheit.

This is the recommended setting by most manufacturers and is sufficient for most households. However, if you live in a warmer climate or have young children or elderly residents in your home, you may want to consider lowering the temperature to 130 degrees Fahrenheit. Gas-fired water heaters typically come with a factory default setting of 160 degrees Fahrenheit.

Again, this may be too hot for some households so you may want to adjust it down to 150 degrees Fahrenheit. If you have an automatic dishwasher, remember that it needs hot water to operate properly so make sure the temperature is not set too low. As a general rule of thumb, we would recommend not setting your water heater above 150 degrees Fahrenheit unless absolutely necessary.

This will help prevent scalding accidents and save energy at the same time.

Is 120 Water Hot?

Yes, 120 water is hot. In fact, it’s boiling! At sea level, water boils at 212 degrees Fahrenheit.

But that temperature can vary depending on your location. For example, if you’re at a higher elevation like in the mountains, water will boil at a lower temperature than it does at sea level.

Is 145 Too Hot for Water Heater?

No, 145 degrees is not too hot for a water heater. In fact, most water heaters are set to around 140 degrees. The main reason you wouldn’t want to go any hotter than that is because it can start to break down the pipes and fittings in your home.

What Temperature Should Your Hot Water Be?

If you’re like most people, you probably don’t give much thought to the temperature of your hot water. After all, as long as it’s hot enough to get the job done, what does it matter? Well, it turns out that the temperature of your hot water can make a big difference in both your energy usage and your safety.

The first thing to consider is energy usage. Hot water heater tanks are typically set between 120°F and 140°F, but according to Energy Star, Water heaters account for about 18% of energy use in the average home, so turning yours down just 10°F can save you up to $36 per year on your energy bill. But there’s more to consider than just saving money.

Water that’s too hot can be dangerous. The Centers for Disease Control and Prevention (CDC) recommends setting your water heater at no higher than 120°F to prevent scalding injuries. Every year, thousands of people—mostly children and seniors—are seriously injured by accidentally coming into contact with water that’s too hot.

So if you have young kids or elderly family members living with you, it’s even more important to make sure your water heater is set properly. Of course, finding the perfect balance between comfort and safety can be a bit tricky. If you’re not sure where to start, try setting your water heater somewhere in the middle—around 130°F should be good for most people.

And if you find that’s still too hot or too cold for your liking, you can always adjust accordingly until you find just the right temperature for you and your family.


Your water heater should be set to 125°F (51.7°C). This is the optimal temperature to prevent scalding and bacteria growth.
