What Are Self-Cleaning Water Heaters and How Do They Work?

Working with water heaters is not one of the many DIY (do-it-yourself) plumbing projects that can be accomplished by the average homeowner. Preferred Plumbing Contractors are those that are educated to give the services that your house or property need in order to run plumbing fixtures properly, save money, and preserve vital energy resources.

Self-Cleaning Water Heaters

The use of self-cleaning water heaters is something that a lot of our customers are interested in.Natural water sediment accumulates in the bottom of the water heater over time, causing it to get clogged.It is possible for silt to cover the heating element, causing your water heater to work harder and consume more energy.

These water heaters are designed to automatically manage and minimize the turbidity in their water supply.

How Self-Cleaning Water Heaters Work

Electricity or natural gas can be used to power a self-cleaning water heater.This company’s system circulates the water, which helps to decrease silt buildup.From a technical standpoint, all self-cleaning water heaters operate in the same way.

Water from a cold-water input is used to heat the water, and water from a hot-water output is used to transport the water to your house.Water is stored in the tank until it is required.″A self-cleaning water heater features a curved dip tube and a fitting on the dip tube that swirls the incoming water at the bottom of the tank,″ according to ehow.As a result, the sediment is kept stirred up in the water, and it is forced through the hot-water outlet the next time you use hot water.


Although a self-cleaning water heater is more expensive, the long-term savings should more than make up for the higher initial cost.A small amount of sediment will collect in the tank of your self-cleaning water heater over time, necessitating a draining of the tank every three to four years.The silt (which had previously settled and built in the hot water tank) is now being discharged into your house and through your hot-water faucets, which is a negative.

Water that has been treated with cold water tap water will not contain the sediment, making it safer to drink.Calcium carbonate is the most common type of sediment.

Self-Cleaning Water Heater

Your water heater is a critical component of the overall comfort of your house.Because it is out of sight, we are more likely to consider its presence only when it is absent.Pay close attention, the self-cleaning water heater might provide you with a cold shower twice as often, both literally and figuratively, if the bill for its replacement is not scheduled in advance.

Reading this article will assist you in understanding how to make it last longer for you.There are several low-cost and simple-to-install methods for extending the life of your heater.It enables you to prepare for the replacement of your water heater as it reaches the end of its useful life.Here are some suggestions for extending the life of your gas system.By doing so, you will be less likely to be taken off guard and will also help to extend the life of your self-cleaning water heater.You may also be interested in: Private Drinking Water Wells: Where Does the Water Come From and What Does It Taste Like?

Temperature Of Your Self-Cleaning Water Heater 

Check the temperature of your hot water on a regular basis; this is one of the aspects that determines how long your heater will survive.If the temperature of your water is too high, you will incur additional energy costs and the life of your water heater will be reduced.Additionally, very hot water can cause severe burns to persons with fragile skin, such as youngsters or the elderly.

In a matter of seconds, third degree burns can result from using too hot of water.The temperature at which the self-cleaning water heater components should be installed is 140 degrees Fahrenheit or 60 degrees Celsius in order to minimize the growth of germs.However, the temperature of the water flowing out of your faucet should not be more than 120 degrees Fahrenheit or 50 degrees Celsius.With the help of a high-quality thermometer, you can guarantee that your hot water is at the appropriate temperature.Remember to perform this test when you have not had any hot water for a few hours in order to perform it correctly; this sort of test will also help your system last for a longer period of time.Water that is too cold and continuous might create further difficulties, causing your heater to fail sooner rather than later.

During heavy usage, you may find that you run out of heat quicker.It’s possible that your dishwasher or clothes washer is less efficient.

Save A Little More Energy

As long as your comfort is not compromised, you can gently reduce the temperature of the thermostats that regulate the temperature of the components within your water heater.They are located beneath the hoods in the front, and the height of each piece is determined by them.Lowering the temperature of your water heater elements by a few degrees will save you money on your energy bill and extend the usable life of your system, allowing it to serve you for longer periods of time.

The Sacrificial Anode Extends The Life Of Your Self-Cleaning Water Heater

  1. Sacrificial anodes are devices that help your system survive longer by protecting it from corrosion and punctures.
  2. They are also particularly developed to extend the life of your heater against these problems.
  3. This anode includes magnesium, which draws corrosive substances to it, which can damage the walls of your water heater and pierce them if they come into contact with it.
  4. As a result of the corrosive nature of its operation, this anode does not have an endless useful life.
  5. It is necessary to replace the anode in your self-cleaning water heater every six years, and even more frequently if you reside in a municipality that utilizes chlorine or softeners in the water that it delivers.

This simple maintenance procedure may considerably increase the life of your heater and ensure that it lasts as long as possible.

The Water Drain

  1. Clean out the water in your self-cleaning water heater at least once a year to prevent sediment buildup and to provide a less suitable environment for the growth of bacteria, which is especially important with electricity-powered water heaters.
  2. It is possible that this cleaning could assist to extend the life of your water heater.
  3. Before you begin, remember to cut off the heater’s power source to prevent your objects from running out of fuel and becoming combustible.

Heated Environment

It is critical to ensure that your self-cleaning water heater is put in an adequately heated area. You save money on your energy bills while also contributing to the system’s longevity. Alternatively, you may cover the heater with an insulating blanket to extend its lifespan.

Safety valve and overflow

  1. The safety valve is a necessary component that operates in the event of an internal overpressure in the self-cleaning water heater and discharges any excess water into the sewage system.
  2. Once a year, open and close this safety valve to avoid scale building in its mechanism and to ensure that it functions properly.
  3. If the valve does not entirely close, you have an indication of failure on your hands.
  4. Your heating mechanism has been invaded by an unknown object.
  5. Contact a plumber after turning off the cold water supply to your self-cleaning water heater and turning off the power supply to the heater.

The water from your security system might run into the sewer without you even noticing it, raising your energy cost.The procedures for keeping your water heater in good working order that are given here may differ from one heater to another; see the instruction manual for a better understanding.

Equipped With A Dip Tube

  1. In fact, whether you purchase an electric water heater or even a gas water heater, it will come with a dip pipe already attached.
  2. It is possible that the water heater dip tube or pipe goes right through the middle of the tank.
  3. When cold water is introduced into the tank, the dip tube will be lowered to ensure that it is distributed properly.
  4. Without a dip pipe or maybe tube, your water would just sit on the very top of the tank and would not heat up all the way to the desired temperature.
  5. Due to the continual flow of water into the water heater, sediments might develop in the tank’s lower portion over time, causing it to malfunction.

While self-cleaning water heaters are really constructed with the famous anode rod, which collects minerals, they are not as common.It is an excellent design for removing additional sediments by draining them; all of these features are included to ensure that it will endure for you.It is common for heaters to include a drain valve located at the bottom of the tank that may be opened, which helps them last longer.

This valve is responsible for draining the silt from the tank (this should be done occasionally to keep the tank clean, last and functioning well).In a self-cleaning instantaneous water heater, the submerged tube is curved rather than straight, as opposed to a conventional water heater.This dip tube is fitted with an adapter that allows the water to be turned rather than simply being dumped on the ground.The flow of the water keeps the sediment moving and reduces the amount of drainage required; this, in turn, helps to the longevity of your heater by increasing its efficiency.Water heaters that clean themselves have a lifespan of 8 to 12 years, depending on the brand and qualities!

Regardless of the kind, experts recommend draining two to five gallons of water every day for up to three years to ensure that your water heater lasts as long as possible.


  1. Self-cleaning water heaters are more common in modern tanks; these types of water heaters are more expensive but may survive for many years (8-10 years).
  2. It is recommended that you have your plumber do an annual examination of your plumbing system, which should include your water heater.
  3. Inquire with him at the same time about any information you may require in order to accommodate yourself to the operation of your heater in order for it to endure longer for you.

  • Water heaters that clean themselves
  • how water heaters function
  • It is necessary to address the sediment problem.
  • Self-cleaning water heaters have a number of disadvantages.
  1. Water heaters require periodic emptying of the silt that accumulates at the bottom of the tank.
  2. Even with regular draining, silt accumulates and ultimately takes up more space in the tank, making it less suitable for holding water.
  3. Water heaters that are powered by electricity lose efficiency when the heating element becomes coated with sediment throughout the course of their lives.
  4. Self-cleaning water heaters minimize the amount of sediment that accumulates at the bottom of the tank on an automated basis.


Internal circulation of a self-cleaning water heater helps keep sediment moving, allowing it to pass through the hot water output rather than accumulating at the bottom.

Self-Cleaning Water Heaters

  1. Electric or natural gas can be used to power self-cleaning water heaters.
  2. As long as the water and sediment are flowing, there will be no accumulation on the bottom or on the electric element of the self-cleaning device.
  3. When the water heater is older, this self-cleaning turbulence helps to extend the life of the element, avoid leaks, and ensure that you always have a full tank of hot water.
  4. Despite the fact that self-cleaning water heaters are an upgrade over conventional water heaters, they are not without flaws.
  5. When it comes to operating principles for a tank water heater, it doesn’t matter whether your unit is electric or gas-powered.

A cold-water inlet delivers the water for heating, while a hot-water exit provides hot water to your house and the surrounding area.The hot water is stored in an insulated tank until it is needed.When you use hot water, your water heater will automatically switch over to cold water to conserve energy and save money.

A dip tube is responsible for transporting cold water to the bottom of the tank.A self-cleaning water heater features a curved dip tube and a fitting on the dip tube that allows the incoming water to swirl about at the bottom of the tank, therefore cleaning the tank.This keeps the sediment mixed up in the water, allowing it to pass through the hot-water outlet the next time you turn on the hot water faucet.In your water, sediment is formed as a result of contaminants, mostly calcium carbonate.In order to reduce damage to the heating element as well as scale accumulation in your aquarium, you should agitate your sediment and keep it off the bottom and away from the heating element.

The fact that sediment particles are heavier than water means that they will tend to settle at or near the bottom of the tank, even in the greatest self-cleaning devices.Due to the buildup of silt, the tank begins to overheat at the bottom, and the water heater finally fails and leaks.Although the self-cleaning water heater does not completely remove all of the silt from the bottom of the tank, it does help to limit the amount of sediment that accumulates and thereby increases the life of the tank and element.

Disadvantages of Self-Cleaning Water Heaters

  1. The self-cleaning water heater is more expensive at the time of purchase, but you may be able to recoup some of the money via the unit’s longer life and increased efficiency.
  2. Although a self-cleaning water heater does not completely eradicate sediment, the silt that it does remove is included into your hot water supply.
  3. You may avoid ingesting sediment by using the cold-water faucet for your drinking water.
  4. Eventually, sediment will accumulate in your self-cleaning water heater, reducing its effectiveness and reducing the amount of space available for water storage.
  5. In the event that your water heater has a drain cock at the bottom, you may extend the life of any water heater, including a self-cleaning model, by emptying some water from the bottom of the unit.

Self-Cleaning Water Heaters: How Do They Work (and Are They Worth It)?

Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. But there are a few things you should be aware of when it comes to self-cleaning water heaters before making the decision to purchase one.

What is a Self Cleaning Water Heater?

  1. When you utilize a self-cleaning water heater, the water circulation filters away sediment, minimizing the number of times you have to flush the system.
  2. However, while it does not fully eradicate sediment accumulation, it does remove the great majority of it.
  3. Self-cleaning versions are available in both electric and natural gas configurations.
  4. Remember that there are both pros and downsides to taking this route, and that both should be considered.
  5. The majority of these are concerned with the way in which these gadgets operate.
See also:  How Do You Know A Water Heater Is Going Bad?

How Does it Work?

  1. When viewed from the outside, a self-cleaning water heater appears and operates in much the same manner as their conventional counterparts.
  2. With a dip tube and specific fitting, the water towards the bottom of the tank is constantly stirring, which makes for a more pleasant experience.
  3. Water enters the system through the cold water intake pipe, bringing sediment with it to begin with.
  4. Once in the tank, these undesired things drop to the bottom, lowering the effectiveness of the heater over time as they accumulate.
  5. The tube guarantees that the sediment in the tank continues to spin around, allowing it to be sucked out the next time you turn on the hot water faucet.

Here’s an illustration of what it appears to be:

Is it Worth it?

This can be a difficult issue to answer since it can be broken down into three major topics: cost, efficacy, and health-related concerns. These subjects will either be beneficial or detrimental to you, depending on your specific requirements.


Even though the initial cost is more than that of a regular water heater, the higher initial cost will be mitigated over time by energy savings since the heater will be working at optimum efficiency. And, because time is money, you won’t have to clean your water heater as frequently as you would have in the past.


It has already been established that while a self-cleaning water heater significantly decreases sediment buildup, it is not completely effective. You will, however, need to cleanse the tank approximately once every three years, rather than every six months to one year as previously.

Health Concerns

  1. Water from the cold water tap will stay drinkable, but sediment (mostly calcium carbonate) will be pushed out through the hot water tap, making the water more abrasive on your skin.
  2. Even with a standard water heater, some people believe that hot water should be filtered before consumption; however, this is questionable because all water flowing out of your taps includes minute levels of sediment.
  3. If you’re concerned about this side effect, installing a tap filter may be able to alleviate it to some extent.

Additional Cleaning

  1. Draining and flushing your water heater is a must, even if you have a self-cleaning water heater in your home.
  2. However, did you know that there are additional cleaning activities that can be performed to help extend the life of your water heater?
  3. The following critical chores are sometimes forgotten, but they may all help to extend the life, improve the efficiency, and boost the safety factor of your heater.


  1. In order to prevent hazardous particles from eating away at the heater’s inner lining, anode rods are used in water heaters to attract and hold them.
  2. As a result, it should come as no surprise that monitoring the anode every six months is essential, even if you have a self-cleaning unit.
  3. As soon as that anode begins to show signs of severe corrosion, pay the price of a meal to replace it.
  4. You may also want to consider replacing the original anode rod with a more durable version, or perhaps a powered anode that does not require replacement.


  1. The fact that you have a water heater in your basement or garage, as surprising as it may appear, might imply that it is vulnerable to dust accumulation.
  2. Not only is this unsightly and harmful to those who suffer from asthma and allergies, but it may also clog up components and reduce the efficiency and longevity of your heater, among other things.
  3. Remove any visible dust or debris from the tank’s surfaces as well as the area beneath the tank with a shop vacuum.
  4. It may also be necessary to turn off the heater and gently vacuum out the heating elements and other mechanical components.
  5. Dirt on the casing may be removed by wiping it with a clean, dry cloth.

When it comes cleaning difficult stains, a few drops of Windex or another window cleaner can do the trick.This should be completed on a yearly basis, as should be the case with the majority of maintenance chores.


  1. As previously said, a self-cleaning water heater does not require flushing as frequently as a traditional water heater, but it will still require it once every three years or so.
  2. The procedure for flushing one of them is the same as it is for a normal model.
  3. When using well water that has a high mineral concentration, you may need to flush more frequently.
  4. Draining and flushing a heater should always be done after it has been turned off and allowed to cool for many hours to minimise the danger of burning yourself.

How Self-Cleaning Water Heaters Work: Are they Worth It? Pros & Cons (Explained)

  1. You may have purchased or be tempted to purchase a water heater that has the Everkleen Self-Cleaning Water Heater name and are curious as to how they operate and whether they are even worthwhile.
  2. When it comes to cleaning a water heater, the most common problem is sediment.
  3. It collects at the bottom of the unit and continues to build up as you use the heater to warm up the space inside.
  4. As a result, the notion of a self-cleaning water heater is quite intriguing to a large number of individuals.
  5. But, exactly, how do self-cleaning water heaters function?

In addition to the curved dip tube that is linked to the bottom of the tank, self-cleaning water heaters come with an attachment.The accessory stirs the water that enters the tank, which causes the sediment at the bottom of the tank to become unsettled.The hot water outlet allows the stirring water to be expelled from the heater and into the sink.

It will be discussed in this article how self-cleaning water heaters function, what you can expect from them, and how to keep one in good working order.

What Is the Difference Between A Self-Cleaning And A Non-Self-Cleaning Water Heater 

  1. A dip pipe is included with every water heater.
  2. The dip pipe is the most significant distinction between a self-cleaning and a non-self-cleaning water heater.
  3. It is common for the dip pipe to be straight in non-self-cleaning devices.
  4. With a self-cleaning heater, the dip tube is curled at the bottom and fitted with a little attachment to help with the cleaning.
  5. Because of the accessory, turbulence is created in the water tank, which stirs up silt from the floor.

This is in addition to the anode rod that is included with all water heaters in order to attract and collect minerals from the water.

How Do Self-Cleaning Water Heaters Work?

  1. Water includes contaminants that may pass through the in-tank filtering process of your water heater and into the surrounding environment.
  2. The accumulation of silt impairs the heater’s capacity to heat the water to the appropriate temperature.
  3. The sediment layers surround the bottom of the heater, encircling and protecting the heating element from the elements.
  4. In this way, an insulating layer is formed between the heating element and the water source.
  5. As a consequence, the heater must work harder to heat the water, and even when it succeeds, the water does not reach the desired temperature quickly.

When using a self-cleaning water heater, water enters the device and is directed to the bottom of the tank by the dip pipe, just like it would be with a conventional water heater.However, after the water reaches the bottom of the dip pipe, the attachment at the end of the dip pipe swirls the water as it enters, allowing it to heat up more quickly.Finally, when you use hot water, the sediment-laden water that has been churned up drains out of the hot water outlet into the waste water.

How Long Does A Self-Cleaning Water Heater Last?

  1. A self-cleaning water heater has a normal lifespan of between 8 and 12 years, depending on the model.
  2. The classic non-self-cleaning water heater has a lifespan of between 6 and 12 years, depending on the brand and configuration.
  3. While the difference in lifetime is slight, the convenience provided by the self-cleaning device is enormous.
  4. If you do not have the time to clean your water heater on a regular basis, this can make a significant impact in the long run.
  5. And, with proper care and maintenance, the self-cleaning device might provide service for up to 15 years in some cases.

Different people in the plumbing sector have different perspectives on the subject of water heater maintenance.The use of self-cleaning water heaters is intended to assist decrease the accumulation of sediment; nonetheless, no water heater is completely maintenance-free in this regard.The vast majority of plumbers I’ve spoken with over the years agree that frequent water heater maintenance is a good idea, provided that it is done on a consistent basis.

Water heater maintenance that is performed on an irregular basis or only when issues emerge might bring more harm than good to the appliance.

Here is how to make a self-cleaning water heater last

  1. Flush It Once In A While 
  1. Of course, the unit does not require frequent flushing, but it may benefit from a little hand assistance once every three years or so.
  2. This aids in the removal of any silt that may have escaped the automated self-cleaning mechanism throughout the cleaning process.
  3. The following is a step-by-step procedure for flushing your water heater: Remove the water heater from service by shutting down the thermostat, the power source (gas or electricity), and the cold water supply.

Maintaining the hot water outlet, on the other hand, will allow you to send the water that has been flushed out of the unit to the faucet. Additionally, turn on the water in the bathroom or sink. The fact that you open these two valves guarantees that you do not generate a vacuum in the plumbing lines when draining water from the tank.

After that, open the pressure relief valve to allow the water to drain out more quickly and efficiently.

Connect a garden hose to the drainage faucet on the tank’s bottom. Place the other end of the hose outdoors so that it may drain away properly. Alternatively, a bucket can be used to collect the draining water.

Allow for a full draining of the tank. It is critical to keep an eye on the water that is emptying from the tank. Make certain that all of the brown sedimented water drains away.

You may now flush the tank with water. To flush, turn on the cold water faucet that delivers water to the water heater and turn it on full blast. Turn on the faucet and let it run until the water flowing out of the tank is clean. Allow the water to run for a few more minutes to rinse away any obstinate particles.

  1. Test The Tank’s Pressure Relief Valve
  1. It is critical that you check the temperature and pressure valves on your water heater.
  2. This test should be performed every six months.
  3. Testing the T&P relief valve allows you to keep an eye on the tank for leaks or corrosion that might jeopardize the structural integrity of the unit.
  4. The pressure in the tank is limited by the valve, which prevents explosions.
  5. It is critical to keep a watch on the T&P relief valve in order to detect regions that require repair or replacement.

Remove any debris from the valve to see whether it is stopping the valve from performing its usual open and closure operations as it relieves pressure.When it comes to operating the valves, there is a time restriction on how long they may be used before they must be replaced.Consequently, make certain that your valve is within the time limit and is operating properly.

  1. Inspect The Anode
  1. As previously stated, the anode rod is found in all water heaters and is used to conduct electricity.
  2. The rod collects hazardous minerals and particles that are found in the water and draws them to itself.
  3. Most of the time, the minerals eat away at the tank’s inside lining, producing corrosion and threatening the structural integrity of the unit.
  4. An anode that has to be replaced appears to be severely corroded.
  5. If the corrosion rate in your heater is significant, you may want to consider replacing the anode with a more long-lasting device.
  1. Turn The Thermostat Up
  1. Constant usage of the water heater reduces the lifespan of the appliance.
  2. Because you use the device more frequently, it endures greater wear and tear.
  3. The water, on the other hand, begins to boil when the thermostat is turned up.
  4. If the water is boiling, it will take longer to cool, allowing you to avoid having to turn on the heater all of the time to keep the water warm.
  5. In addition, as compared to lukewarm water, you tend to use a lot less hot water.

Furthermore, because you are using less water, the majority of the hot water that remains is retained in the tank and may be utilized by the next person without the need to turn on the heater.

  1. Check The Heating Element
  1. Keep an eye on how the heating element is doing.
  2. In most cases, the heating element should last between 6 and 10 years.
  3. When you turn on the water heater, you should notice that the water is constantly lukewarm to chilly.
  4. This is an indication of a faulty heating element.
  5. The following factors might cause the heating element to malfunction: Mineral deposit accumulation is characterized by the following characteristics: Due to the mineral sediments around the element, the element fails to operate properly.

A faulty thermostat: When the thermostat fails to regulate the amount of heat that is sent to the element, the latter will be exposed to excessive heat and burn.

Pockets of trapped air: These cause the segment of the element that is not immersed in water to burn because of the heat generated by the trapped air.

A structural failure might occur as a result of the element’s age or as a result of a power surge. Elements have a voltage rating that, if exceeded, results in a component that is completely damaged.

Poor connections: Wire connections to the element might be compromised, or they can be the product of shoddy construction. Poor connections: For example, if a wire is accidentally pulled away from the termination, the element may burn.

Because this is an electric appliance, it is recommended to contact a plumbing specialist who is equipped with the necessary and appropriate gear to inspect the element. Schedule a regular check that should take place at the same time that the temperature and pressure relief valve inspections are performed.

  1. Remove Dust 
  1. Rather of installing their water heaters in visible locations such as the garage or basement, many individuals opt to conceal them in these locations.
  2. Unfortunately, there is a lot of dust in these locations.
  3. Dust can build in the heater’s components and clog them, reducing the unit’s efficiency and limiting its useful life.
  4. Remove any visible dust from the tank’s surface using a shop vacuum before continuing.
  5. Additionally, concentrate on the region beneath the heater.

You may also use a towel to remove any dust that has remained on the surface.The frequency with which dust is removed might range from every six months to once a year, depending on where you reside.

Advantages of Self-Cleaning Water Heaters

  • Ease Of Maintenance
See also:  What Water Filter Removes Viruses?

The fact that these units are self-cleaning means that they have little to no silt buildup. There is little doubt that you will still need to flush the system, but this should be done every three years rather than every six months. Even in this case, the quantity of silt you may detect is far less than in a unit that does not self-clean. It saves both money and time.

  1. These units are energy efficient due to the fact that they operate quickly and efficiently.
  2. The unit will be operating at peak performance at all times, which means it will only require minor repairs and maintenance.
  3. The more smoothly your water heater operates, the less energy it requires and the more money you save on your energy bills.
  4. Additionally, you will not have to spend any time cleaning your tank.
  5. You may use that time to accomplish something that you enjoy doing instead.


Being relieved of the responsibility of arranging heater cleanings on an as-needed basis is quite handy. With a self-cleaning device, you may continue to use it without having to worry about the tank being clogged with sediment layers over time. Efficiency

Self-cleaning water heaters assist in the control of sediment issues, allowing the heating element to operate more efficiently. The decrease of silt on the tank’s bottom also has the added benefit of extending the tank’s overall lifespan. Because there is little silt in the tank to induce corrosion, leaks are not common in this configuration.

Disadvantages of A Self-Cleaning Water Heater

  • Expensive Initial Cost

When compared to its non-self-cleaning sibling, the initial cost of purchasing this water heater is somewhat expensive. It does not completely remove all of the sediment.

Unfortunately, even the most effective self-cleaning water heater will not be able to remove all of the sediment. In other words, some sediment can still be discovered in self-cleaning devices. It is for this reason that even self-cleaning water heaters require flushing on a yearly basis.

What To Consider When Buying A Self-Cleaning Water Heater

  1. Cost

With a self-cleaning device, the prices of purchase and installation are more expensive. However, the good news is that the high initial cost will be mitigated over time as you will save more money by utilizing this unit than with a non-self-cleaning unit over time.

  1. Size

The capacity of the unit increases in proportion to its size. Because tankless water heaters are so handy, you may find that acquiring a larger unit for your primary home needs is a better investment in the long run.

  1. Energy Efficiency

The water heater must be energy efficient in order to reduce the amount of money spent on associated energy bills. The majority of models now on the market are energy efficient, with some even earning the Energy Star designation.

  1. Warranties

It is preferable to get a model that comes with an extended warranty. Durable, high-quality units are more likely to have longer warranties, with some even covering the heater’s whole service life. Trustworthy companies that believe in the quality of their products are more likely to trust that their items will endure the 12 years that they have promised.

Are All Water Heaters Self-Cleaning

  1. Not all water heaters have the ability to self-clean.
  2. Self-cleaning units have been particularly designed to keep a low level of silt and impurities in the water supply.
  3. However, the good news is that self-cleaning water heaters are now available for virtually all types of water heaters.
  4. Self-cleaning water heaters are available in a variety of configurations, including electric, gas, and tankless.
  5. Flushing a tankless water heater to remove scale is significantly faster and less difficult than flushing a tank-style water heater to remove scale.

The heater’s electrical circuit should be turned off within the breaker panel.If it’s a gas-powered machine, turn off the gas valve immediately.

Shut off both the cold water supply to the heater and the hot water valve, which is responsible for delivering hot water to the faucet.

Connect one end of a garden hose to a sump pump and the other end to a cold water isolation valve to complete the installation. Connect a second hose to the hot water isolation valve in the plumbing system.

Placing the pump and second hose into a bucket with five gallons of clean, unused vinegar is a good way to save money. To do this, open both the hot and cold isolation valves at the same time and let the pump to circulate vinegar through the heater.

Pour vinegar into the heater and let it to drain out via the hoses after the pump has been running for at least 45 minutes.

Finally, turn on the cold water faucet and allow the water to run for five minutes before turning it off. It’s important to remember to clean the intake filter screen as well, to ensure that any silt is removed.

You can now disconnect the hoses and open the hot and cold water isolation valves, if they are still closed. A few of faucets should be opened throughout the house to release any trapped air that might be affecting the plumbing lines.

How Do Self-Cleaning Water Heaters Work?

  1. We may not need to utilize our heating system all year, but we do make use of our hot water heaters.
  2. The amount of water that passes through the water heater tank is significant, and with it comes minerals and contaminants from the various appliances in the house.
  3. The frequency with which you must clean your water heater tank is determined by whether you have a traditional water heater or a self-cleaning kind.
  4. Here’s what we can tell you about the differences: Any water heater, whether it’s an electric or a gas water heater, is going to be equipped with a dip tube.
  5. It goes straight down through the centre of the tank, and when cold water is introduced into the tank, the dip tube transports it to the bottom of the tank in order to ensure that it is distributed appropriately.

The water would merely sit at the top of the tank if there was no dip tube, and it would not be sufficiently heated otherwise.With so much water being fed into your water heater on a daily basis, it is inevitable that sediment will accumulate at the bottom of the tank over time.In the case of sediment, it is just the presence of contaminants such as calcium carbonate in your water.

The anode rod in water heaters absorbs minerals; nonetheless, it is still a good idea to drain the water heater to remove any additional silt that has accumulated.The majority of water heaters are equipped with a drain valve located at the bottom of the tank, which may be opened.This valve will drain the sediment from the tank (this should be done on a regular basis to maintain the tank clean and functioning properly).In the tank of a self-cleaning water heater, you’ll discover a curved dip tube rather than a straight one, which makes cleaning easier.This dip tube will be fitted with a fitting that will swirl the water around rather than just discharging it to the bottom.

By spinning the water, it helps to keep the silt flowing and reduces the amount of draining required.Hot water heaters have a lifespan of between 8 and 12 years, depending on the manufacturer and features.If you have a tank water heater, removing 2-5 gallons of water every one to three years can help to increase the life of the tank.Our water heater installation specialists recommend doing this regardless of the type of tank you own.

Common Components of Electric Water Heaters

  1. These types of water heaters use electricity to heat the water in the tank that they are installed in.
  2. Top-mounted, built-in electric junction box that is ready to accept 1/2″ or 3/4″ conduit guarantees that installation is as simple as possible.
  3. INSULATION MADE OF FOAM To keep heat trapped inside the tank and save energy, a thick layer of ecologically friendly non-CFC polyurethane foam has been applied around the outside.
  4. RELIEF VALVE FOR THE TEMPERATURE AND PRESSURE The temperature and pressure relief valve is a safety element that permits the tank to alleviate excess pressure if a circumstance develops that necessitates pressure relief from within the tank.
  5. HEATING ELEMENTS WITH TWO CONTROLS Copper elements with a power of 4500W and a voltage of 240VAC enable rapid recovery and good efficiency.

Some types use stainless steel pieces that are designed to survive for a long time, thus increasing their dependability.ANODE ROD The anode rod, which is installed at the top of the tank, protects it from the corrosive effects of hot water, allowing it to last longer.When it comes to water heater maintenance, anode rods are sacrificial elements that should be examined for depletion on a regular basis.

THE INTERIOR IS MADE OF GLASS.We coat the interior of the tank with porcelain enamel glass in order to protect it from corrosion, chemical resistance (acid or alkaline), and thermal shock during the manufacturing process.EFFICIENT AND LONG-LASTING DIP TUBE Our electric water heaters are equipped with an automatic self-cleaning dip tube, which helps to reduce sediment in the tank while extending tank life and increasing efficiency.CERTIFICATION It complies with the criteria of the UL 174 code, as well as the newest version of the National Appliance Energy Conservation Act and the U.S.Department of Energy’s energy efficiency guidelines.

Drain the Water Heater

  1. Connect a garden hose to the hose bib located near the bottom of the water heater and run the hose to a floor drain or an exterior place to collect any excess water from the water heater.
  2. Note: If you have a drain pan beneath your sink that is properly connected to a drain, you will not need to use a hose.
  3. Turn off the water heater’s electricity, or turn the gas control valve to the ″Vacation″ position, whichever is appropriate.
  4. Close the cold water entry valve, which is normally found at the top of the tank.
  5. This will prevent the tank from overheating.

Open the drain valve and turn on the hot water faucet nearest to the tank to allow air to circulate through the tank.See also: How to Unclog a Water Heater That Won’t Drain (with Pictures).Allow for complete emptying of the tank before proceeding.

Larger hot water heaters will, of course, take a little longer to drain, but it should not take more than a few minutes in most cases.Take the garden hose and disconnect it from the drain valve.If your water heater has a plastic drain valve, now is an excellent time to replace it with a brass drain valve, which will last longer and be more sturdy.Remove the drain valve and replace it with the brass valve, which should be done with a big adjustable wrench.

Cleaning and Flushing the Tank

  1. If you go to your local hardware store, you can purchase a long, narrow brush (like this one) that is intended for cleaning refrigerator coils but is also excellent for cleaning water heater tanks.
  2. Insert the brush into the opening left by the drain valve after it has been disassembled.
  3. Scrape the bottom of the tank and as much of the interior sides of the tank as you can with the brush, being careful not to scratch the surface of the tank.
  4. In the event that your tank has not been cleaned in a while, this process may take some time.
  5. The greater the amount of sediment that can be broken loose, the better the performance of your water heater.

A short 3/4 inch plumbing nipple should be screwed into the drain hole.Drain valves are not suitable for tank cleaning because they are easily clogged by the debris that will be flushed out, and therefore are not recommended.Place a bucket right below the plumbing nipple or attach a garden hose to the other end of the nipple (or let it drain into a properly fitted drain pan) (or let it drain into a properly installed drain pan).

Make sure to place the other end of the hose (if you are using one) into a bucket so that you can see the results of your cleaning efforts.Connect a hose to the cold water inlet valve and turn it on for a few minutes until the water coming out of the hose is clear.Remove the nipple and repeat the operation until no further particles are flushed out after cleaning.Some material, such as rust or calcium deposits, may be present in the bucket.Note:  Many contemporary water heaters contain “self-cleaning” function.

Although it is beneficial, you should still manually flush and clean a water heater, but you will not have to do so on a regular basis.As a result, rather than cleaning once a year, it is recommended that you do so every three years or so.

Completing the Project

  1. Turn off the hot water faucet if it is still running.
  2. Rather than replacing the drain valve, you may install an inline ball valve at the end of the nipple to make future cleaning easier and more convenient.
  3. It will be necessary to install a second, short nipple to the valve’s outflow side.
  4. Wrap plumber’s tape over the threads on both sides of the nipple and tighten the nipple into the tank until it is completely secure.
  5. Screw the ball valve into place and tighten it down completely.

Open the cold water inlet valve by turning it to the on position.Activate the hot water faucet and let the water to run until all of the air has been expelled from the pipe.As soon as all of the air has been withdrawn from the tank, reconnect the electricity or turn on the gas control valve to the ″On″ position again.
