How Long Should a 40-Gallon Water Heater Stay Hot?
If you’re in the middle of a shower and you run out of hot water, you’ll immediately feel the sting of cold water stinging your skin. That’s a frigid annoyance that no one wants to deal with on their vacation. It is normal for families with two to four persons to have a 40-gallon water heater on hand. These tanks are frequently seen in homes with 1.5 bathrooms or less. A 40-gallon water heater in your house that quickly runs out of hot water may indicate a problem with the unit. Check to see how long your 40-gallon water heater should keep the water hot, and why it may be running out of hot water more quickly than it should be doing.
How Long Should a 40-Gallon Water Heater Stay Hot
When not in use, hot water stored in a well insulated tank should remain hot for a day or two at a time, on average. If everything goes as planned, a 40-gallon water heater should be able to produce hot water consistently for 45 minutes to an hour. In actuality, the length of time required varies on a variety of factors, including:
How Many Hot Showers Can You Get from a 40-Gallon Water Heater
Generally speaking, a regular shower uses around 10 gallons of water for each usage. That implies you may have up to four showers from a 40-gallon water heater in the course of an hour on average, according to the manufacturer. That is, as long as you restrict your hot water use to simply showering and no other equipment or activities. The majority of the time, though, you use your hot water in other places like the dishwasher, laundry, or even the bathroom faucets to wash your hands. All of these activities and equipment can drastically reduce the amount of hot water available in your home.
In the end, the number of hot showers you can receive from a 40-gallon water heater is determined by how much water you use in the shower and elsewhere in your home.
What Is Water Heater Recovery Time?
The recovery rate of your water heater is the amount of time it takes to heat the water remaining in the tank after all of the hot water has been utilized. The amount of time it takes for your water heater to recover is dependent on the size of the water heater as well as the type of water heater you have. When compared to electric water heaters, gas water heaters are often more efficient. Consider the following example: a 40-gallon natural gas water heater may be recovered in around one hour, whereas an electric water heater can take twice as long.
Why Your 40-Gallon Water Heater is Running Out of Hot Water Too Fast
It is important to determine whether the problem with your 40-gallon water heater has existed for some time or whether this is an ongoing issue that has only recently surfaced. In the first case, you may have found yourself constantly running out of hot water, despite your best efforts to reduce your hot water consumption.
Your 40-gallon water heater just does not have adequate capacity. Your current tank is far too tiny for your requirements, and you should consider upgrading to a larger one. However, if you have only lately noticed a shortage of hot water, you may be experiencing one of these issues.
- Your water heater has reached the end of its useful life. Over time, water heaters lose their efficiency. As a result, it is reasonable to assume that your old water heater is no longer capable of heating the water effectively or fully.
- Problems with the thermostat. Water heaters are equipped with a thermostat, which is used to regulate the temperature of the heated water. It is possible to adjust the thermostat to the desired hot water temperature, however the thermostat may malfunction or break down from time to time. When this occurs, the efficiency with which your water heater heats the water to the temperature you desire is reduced significantly.
- Sediment Accumulation. In most cases, unless you’re using filtered tap water, the water that comes into your home might include sediment. These minute mineral particles can accumulate at the bottom of the tank, and the sediment accumulation can restrict the quantity of hot water that can be stored by your water heater over time.
When to Replace Your Water Heater Tank
When a family grows, it’s easy to neglect to improve home appliances, such as a water heater, to accommodate the additional members. However, imagine the number of persons in your family grows in the future. If this is the case, you should consider upgrading your present water heater to a larger one in order to suit your family’s rising demands while keeping everyone happy and comfortable. Please see the following graphs to assist you in selecting the best water heater tank for your household needs.

- Sixty gallons or more for six people or more
Also, consider adding an additional 10 gallons for each new person in your household.
When to Replace the Entire Water Heater System
If you’ve lately realized that your 40-gallon water heater is always running out of hot water, it’s possible that the equipment is too old to perform properly. In this instance, the most cost-effective solution is to replace the complete water heater system. The time has come for you to replace your home’s water heating system if it’s more than 10 years old and is no longer capable of heating water as efficiently as it once did. However, if you do decide to replace the complete unit, you should consider upgrading to a larger tank to satisfy the demands of everyone in your household.
How Long Should a Water Heater Provide Hot Water Per Shower?
The amount of hot water that your water heater should be able to deliver every shower is mostly determined by the size of your hot water storage tank. For example, a regular shower consumes around 10 gallons of hot water on average. As a result, if you have a 40-gallon hot water tank, you should be able to take four showers of normal duration before your tank runs out of hot water. Additionally, it is dependent on how much hot water you use for other purposes. Consider this: you run your dishwasher with hot water just before you go into the shower, right?
Also take into consideration how frequently people in your household wash their hands with hot water.

New Hot water heater (40 gal), how water only last 10 minutes. Is this normal?
Beachboy makes an excellent argument. When I purchased my first home, it came equipped with a 40-gallon water heater that was installed beneath the kitchen counter. It was impossible to take a fifteen-minute shower without running out of hot water with the original components in place. I ended up putting 3,000 watt elements and wiring them so that the top and bottom elements could operate simultaneously, as well as adjusting the thermostats to around 140 degrees. That enabled both my wife and myself to have fifteen-minute back-to-back showers, or to take a single shower while running the clothes washer and drying the clothes afterwards.
I don’t care for “Navy” showers, which consist of a rapid rinse, soaping up, and then rinsing again in under five minutes.
Gunguy, a gas water heater re-heats water approximately five times faster than an electric water heater, so a 40 gallon gas water heater can indeed provide enough hot water for several people IF the thermostat is set at approximately 140 degrees and there is a five to ten minute recovery period between showering.
Around 20 or 25 years ago, safety organizations began to raise awareness of the number of injuries caused by excessively hot water in the home, particularly among the elderly and children, and many states passed legislation requiring water heater thermostats in public and rental facilities to be set at a temperature of no more than 120 or 125 degrees Fahrenheit.
Lower temperature settings have the disadvantage of reducing the amount of hot water that a given size of water heater can provide while also encouraging the development of hazardous bacteria if any such bacteria were present in the incoming water.
Then there’s the issue of energy efficiency to consider.
Simply put, it is this need for lower temperatures for the sake of safety and energy efficiency that has been the driving force for the widespread adoption of tankless water heaters.
How long will a 40 gallon hot water tank last?

On With a 40 gallon tank, the average amount of hot water should last approximately 20 minutes, and with a 60 gallon tank, the average amount of hot water should last about 30 minutes. This is presuming that you just run hot water and don’t mix it with cold water at any point. A hot water tank has a capacity of around 2 gallons per minute.
1.How long should hot water last in the shower with an energy saving shower head?
Generally speaking, a 40 gallon hot water tank should provide enough hot water to last around 20 minutes. This would be based on the assumption that the hotline was completely on the hot side of things. Shower duration can be extended by up to 45 minutes on a 40 gallon tank if the hot and cold water are mixed together during the mixing process. If you choose the 60-gallon tank, you will be able to run for up to an hour and a half. Alternatively, 30 minutes of completely hot water. This is based on the assumption that you are using a standard showerhead.
As a general rule of thumb, you may add 30 percent to each of these times.
2.Why does my hot water run out so fast?
It’s possible that you’re running out of hot water due to excessive consumption. Using a showerhead that is inefficient. Alternatively, it might be that shower times are simply too long. Additionally, you might be experiencing problems with your hot water tank, which would cause you to run out of hot water more quickly. If you have a thermostat problem with your hot water tank, it can substantially limit the amount of time you have before you run out of hot water.
If you have an electric hot water tank, you may also have power outages, which will restrict the amount of hot water you can obtain out of the hot water tank.
3.How can I reduce water usage
Showering for shorter periods of time might help you save money on your hot water bill. Installing a showerhead with an energy-saving function. Reducing the temperature of your tank from 140° to 130° is a good idea. Cool water should be used to wash linen and dishes. Cold water should be used to brush teeth and wash the face. In addition, a hot water tank blanket may be used to extend the amount of time the tank is left idle, hence increasing the efficiency of the hot water.
4.How long does it take for hot water to come back
Heat the hot water from a chilly tank might take up to three hours from a cold tank. If you have a 240 V tank, this is what you will need to do. It normally takes approximately an hour for the water to heat back up once it has cooled down. Once again, this is a conventional home hot water tank, which is typically 40 gallons in capacity. If you choose for an instantaneous hot water tank, you will just be dealing with that. The effect is immediate, and you should not run out of hot water as a result.
5.How To Never Run Out Of Hot Water
It might take up to three hours to heat up hot water from a cold storage tank. If you have a 240 V tank, this is what you will need to use. It normally takes approximately an hour for the water to heat back up after it has been allowed to chill down. A normal home hot water tank, typically 40 gallons in capacity, is seen here. An instantaneous hot water tank is exactly what it says it is: immediate hot water. The effect is immediate, and you should not run out of hot water as a result of this procedure.
6.What Is A Tankless Water Heater?
In addition to this strategy, you may also purchase an instantaneous hotwater heater for your home. Within an instantaneous hot water heater is a very large electrical element that provides a lot of heat. It instantly hyper heats the water as it goes through, causing it to come out hot while the water is cold. We also used our on-demand hot water service. Is that it only works when you request hot water from the faucet? When it comes to efficiency, this is not the most cost-effective option when it comes to your power bill.
It is not necessary to have one of these rapid hot water producers in every residence.
If you don’t, you might end up with a flooded house.
Instantaneous hot water units are installed beneath the locations where hot water is required.
Under a bathroom sink or laundry tub, for example. They make these units incredibly compact, in fact, they are small enough to plug into a wall outlet. Here you may view some of the most ridiculous instantaneous hot water gadgets on the planet.
7.Can I turn up the temperature to make it last longer
The temperature of a conventional electric hot water tank is 140°F. You may set them to as high as 150 or 160 degrees Fahrenheit. Yes, this will, by nature, extend the life of your hot water while you’re mixing because the temperature rate coming out of the hotline is higher. It is recommended that you exercise extreme caution if you plan on doing so since you can easily reprimand yourself, which can be potentially hazardous to yourself. If you have youngsters in the house, we do not advocate doing this since they will not understand the consequences.
The majority of individuals will lower the temperature of the tank to 120°F.
To achieve the same quantity of desired hot water temperature in the shower, you will need to mix it at a higher setpoint on the top when you have through mixing it.
8.Are tankless hot water heaters better?
We do feel that tankless water heaters are superior, and we have evidence to support this. There are a variety of reasons why they are preferable. You don’t have a physical tank for the water to sit in, which would corrode the tank over time. When you ask for hot water, you’re merely requesting power or an ignition source, not anything more. Consequently, there are a variety of advantages to using these. According to what I previously stated, the drawback of these is that you must ensure that you have adequate electricity coming into the house.
- If you want to put it another way, some electrical power panels are merely 100 amps, but most recent residences have 200 amps.
- If you use your stove and dryer at the same time, your main power will be interrupted.
- In the event that you decide to go with electric, we advocate installing smaller tankless hot water heaters under each separate location as previously discussed.
- It is essentially a boiler that produces hot water when you need it.
9.Does the tank produce less hot water when it gets older?
Water heaters without tanks are superior, in our opinion. Many factors contribute to their superiority. Water cannot accumulate in the absence of a physical tank, eventually corroding the tank. When you ask for hot water, you are merely requesting electricity or a source of ignition. The fact is that they have many benefits in general. However, as previously said, the downside of these is that you must ensure that there is sufficient electricity coming into the property. Some of these tankless water heaters can utilize as much as 120 Amperes of power during peak operation.
If you simply use 120 A for your hot water and the remaining 80 A for the rest of your house, you’ll save money on your electricity bill.
Therefore, if you are building huge tankless heaters, we recommend using an alternative fuel source, such as oil or propane instead of natural gas.
With these tankless hot water heaters, there is hardly no recovery time required at all. The main function of these devices is to provide hot water when needed.
10.So What Can I Do?
As you can see, when it comes to determining how long hot water should be kept hot in the shower, a variety of factors come into play. If you are unsure about any things that you may perhaps consider for installation in your house, please see our recommended products page for more information.

That dependable item that has consistently provided hot water for bathing, washing, laundry, and cooking for many years is the water heater. Homes with one or one-and-a-half baths are most commonly equipped with a 40-gallon hot water tank.
Speed of Recovery
Water heater recovery time is the amount of time it takes for a water heater to reheat its full supply of water. The recovery time varies depending on whether the water heater is a gas or electric model. A gas water heater will recover in half the time it takes an electric unit to do the same thing. Typically, a 40-gallon gas water heater will recover in around one hour. Approximately two hours are required for the recovery of a 40-gallon electric water heater.
It may be necessary to upgrade your 40-gallon water heater to a larger one if the recovery time of your water heater causes you to miss out on hot showers on a regular basis. A 50- or 80-gallon water heater may be more appropriate. One additional option is to use a tankless water heater, which warms water only when it is required.

Make a list of everything you may require hot water for that isn’t already on the list, but that you would want to use at peak hour. You’ll need to get a water heater that will meet your demands now that you’ve determined the maximum amount of hot water you’ll need every hour in your house. New storage or tank-type water heaters are labeled with the Energy Star rating. The “initial hour rating” may be found in the upper left corner of the label in the upper left corner of the label.

The first hour ratings are determined by the kind of heat source, the size of the heat source, and the capacity. Other 40-gallon electric water heaters may have a greater or lower first-hour rating than the one shown in the illustration. You’ll want a water heater with a “first hour rating” that corresponds to your peak hour demand, as shown in the table. As you can see from the chart, it is feasible to stretch out your hot water demands and save money on your energy cost by getting a lower capacity water heater.

Did you know that water heaters are available in a variety of sizes? The appropriate size for your home is determined by the number of people who will be living there. It ultimately boils down to a question of supply and demand. The greater the number of individuals having hot baths, the greater the amount of hot water required. If you have a large family, you may want to consider investing in a larger water heater to accommodate them. The majority of families have hot water tanks that hold 40-50 gallons.
When you have more than four people living in your house, most manufacturers recommend installing a 50-80 gallon water tank, according to the manufacturer.
You Need to Clean Out Your Water Heater
When was the last time you cleaned out the inside of your hot water tank? Too many homeowners are unaware of the need of draining and flushing their septic tank. Minerals are naturally occurring in water. These microscopic particles are difficult to detect, yet they are present. Over time, the minerals settle to the bottom of the water heater, forming a thick layer of sludge on the bottom of the tank. Sediment takes up precious space within your water heater tank, making it less efficient. If you find yourself running out of warm water more quickly than normal, you should call a plumber to flush the tank.
The Thermostat Isn’t Working
Every water heater is equipped with a thermostat that regulates the temperature of the water. When the temperature within the tank falls below a certain point, the thermostat activates the heating mechanism. If this critical component were to fail, the water within the tank would become either too hot or too cold. Occasionally, the thermostat will fail. This isn’t unusual. Increasing the temperature setting may be necessary in some cases to resolve the issue. If it does not, you may be need to purchase a replacement part.
Not only will they repair the thermostat, but a plumber will also examine the heating element as part of the process.
Your Water Heater Is a Senior Citizen
When it comes to water heaters, the younger the model, the better the deal. Newer versions are more energy efficient and are less prone to run out of water too soon in comparison to older types. With time, the parts of your water heater will begin to wear down. As soon as your unit reaches the ten-year mark, it’s time to start saving money for a new one.
The majority of households must replace their water heaters after ten years. If you are having difficulty getting enough hot water for your home, check the age of your water heater. It’s possible that you’re overdue for an upgrade.
The Water Heater Experts
When it comes to water heaters, the younger the model, the greater the performance and efficiency. Models from the latest generation operate more effectively and are less prone to run out of water prematurely. With time, the components of your water heater wear out. As soon as your unit reaches the ten-year mark, it’s time to begin saving money for a new one. The majority of households must update their water heaters once every ten years or less. If you are having trouble getting enough hot water for your home, check the age of your water heater.
Solved! How to Select the Right Water Heater Size
Image courtesy of istockphoto.com Q: Our water heater is nearing the end of its useful life. I’ve turned up the temperature on the tank to its highest level, but the water that comes out of the faucet is no longer hot at all. It is therefore necessary to purchase a new water heater. Our present tank has a 30-gallon capacity, which was plenty when we purchased the property ten years ago. However, our family has expanded, and we are now consuming more water for bathing and laundry than before. What type of water heater do I require?
And you’re absolutely correct: Increased people in the family means more water consumption.
“The output is more or less fixed,” he adds.
For a tank-style heater, household size is a simple indicator of hot water needs.
Based on the number of people living in the residence, you may estimate the required tank capacity (in gallons) as follows:
- For one or two people, 23 to 36 gallons are needed, for two to four people, 36 to 46 gallons are needed, and for three to five people, 46 to 56 gallons are needed
- For five or more people, more than 56 gallons are needed (add 10 gallons for each extra person).
A 40-gallon water heater, such as A. O. Smith’s ProLine Power Vent Gas Water Heater (available from SupplyHouse), should be sufficient for the average household of four. However, it should not be your only factor to consider. It is possible to obtain a more realistic picture of your family’s hot water requirements by delving a bit further.
In addition to tank capacity, consider a water heater’s first hour rating.
When a tank is fully heated, the first hour rating (FHR) specifies how much hot water it can generate in a single hour when fully heated. At peak consumption, this statistic indicates the appliance’s efficiency (how rapidly the water heater can reheat the water) and provides an indication of how much water it can manage in a given amount of time. A 50-gallon ProLine Power Vent Water Heater (available fromSupplyHouse) has an FHR of 90 gallons, which means it can supply up to 90 gallons of hot water in an hour, as an illustration.
Make use of the statistics in the table below to help you predict peak hour use and establish the best FHR for your situation.
- Bathing or showering (per person) requires 20 gallons
- Washing hair (per person) requires 6 gallons
- Washing hands (per person) requires 2 gallons
- Washing dishes by hand requires 6 gallons
- Shaving requires 3 gallons
- Running the dishwasher requires 14 gallons
- Running the clothes washer requires 30 gallons.

If a larger tank won’t fit in the existing space, consider a tankless heater.
Tankless heaters, which are often wall-mounted, are able to fit into smaller spaces since they do not require a large storage tank, as O’Brian points out. Typical tank water heaters may be up to six feet tall and 22 inches in diameter, with a capacity of 50 gallons. An alternative tankless water heater with equivalent power, for example, the Takagi Tankless Natural Gas Water Heater (available from SupplyHouse), is just 20 inches high, 14 inches wide, and less than 10 inches deep, making it an ideal choice for small spaces.

To select the right tankless water heater, estimate the necessary flow rate based on hot water usage and the required change in temperature.
Tankless water heaters do not have a storage tank to hold hot water. Instead, they heat it only when it is required. “Flow rate is the most important factor to consider when sizing a tankless water heater,” O’Brian explains. The following information will assist you in estimating the flow rate requirements for your family.
- To begin, figure out how much hot water you use during peak hours. Peak consumption is defined as the period of time during which you consume the largest amount of hot water. In order to compute the maximum amount of hot water you would consume at one time, consider the following list of typical flow rates (per fixture) in gallons-per-minute (gpm)
- Water flow rates for sink faucet: 1 gpm
- Bathtub: 3 gpm
- Shower: 2.5 gpm
- Dishwasher: 3 gpm
- Clothes washer: 3 gpm
- 1.25 gallons per minute (gpm) for the sink faucet
- 3.25 for the bathtub and shower
- 3.25 for the dishwasher and 3.25 for the laundry.

Whether your unit has fully failed or is growing old and incapable of withstanding the heat, investing in a new water heater can improve the quality of your showers and cleaning. It is critical to get the sizing of the tank precisely correct in order to avoid running out of water. The size of the tank is important, but there are other factors to consider as well.
Importance of Proper Sizing
Having a water heater that is too small will have the most visible influence on your everyday life since it will be unable to keep up with your hot water demands. At busier periods, such as in the mornings when everyone is getting ready for work, this is most obvious. It can also occur if you are using hot water for many purposes at the same time, such as showering, cleaning dishes, and doing laundry. Buying the largest water heater you can find is also not the best choice, unless you require a water heater of that size.
When you analyze your requirements to choose the appropriate size of water heater, you may achieve a good balance between hot water and energy efficiency.
Both 30- and 40-gallon water tanks are on the tiny side and are best suited for groups of no more than a handful of individuals.
A 40-gallon water heater will usually be plenty for a household of three to four people, but if you use a lot of hot water, you may need a larger tank.
Examine the amount of hot water you use on a regular basis, as well as how you use it. An audit of your water use can help you understand if you have high needs at specific times of the day and how much hot water you require on a daily basis. Some of the questions to ask are as follows:
- How many showers do members of your household take each day
- Do a large number of individuals take showers at the same time of day? What is the duration of showers
- Is it common for you to utilize deep, big tubs on a regular basis? Approximately how many times do you run your dishwasher? Do you use hot water to wash your clothes? If so, how many loads do you complete on a weekly basis on average?
These questions compel you to consider how much hot water you consume on a daily basis and how much hot water will be required to keep up with the current demand.
Water Heater First-Hour Rating
In order to determine how much hot water a tank-style water heater can generate in an hour, the first-hour rating must be taken into consideration. This rating is calculated assuming that the tank has a full tank of hot water at the start of the hour. The size of the tank is important, but the burner or heating element also has an impact on the first-hour ratings. The amount of heat produced and the source of that heat can both have an impact. Based on your water use, you may calculate what sort of first-hour rating you require.
Maybe you give the kids a bath, take a shower yourself, load the dishwasher, and put a load of laundry in the washing machine at night.
The CenterPoint Energy website states that filling an average bathtub takes 15 to 25 gallons, showering takes around 3 gallons per minute, running a dishwasher takes approximately 5 to 10 gallons, and running a washing machine takes 25 to 40 gallons each load.
Reading Water Heater Specs
All new tank-style water heaters must be labeled with the EnergyGuide label, which provides you with important information about the item. Whenever possible, the first-hour rating should be displayed in the upper-left corner of this label. Following the label “capacity (first-hour rating),” a gallon measurement should be included. This informs you how many gallons of hot water the tank should be able to generate in an hour if it is started with a full tank of hot water in the tank. You should double-check the unit’s label to ensure that it can offer you with adequate hot water throughout your peak consumption periods.
