Simple Tips for Maintaining Your Navien Unit
Some maintenance operations should be conducted on a regular basis in order to maintain Navien units working at top performance and to extend their life expectancy.These treatments include: Listed below are a few straightforward measures you may take to ensure that you get the most out of your Navien machine.NOTE: The frequency of maintenance will vary depending on the unit’s installation, location, use, and operation.Installation, location, use, and operation are all factors to consider.Inspect and clean the water inlet filters.Stainless steel water screens are installed on the cold water input of all Navien tankless water heaters, and the NPE-Advanced versions include an extra screen on the recirculation inlet.
Water screens are installed on the DHW cold-water connection, and there is also a screen installed between the heating supply and return connections on Navien combi-boilers.The return connection of Navien NHB boilers is equipped with a screen.Remove and clean the air filter.All Navien units (water heaters, combi-boilers, and boilers) are equipped with input air screens, which are located within the cabinet immediately below the air intake collar.These screens prevent debris from being drawn into the blower, burner, and heat exchanger assembly.Condensate traps should be cleaned regularly.
This trap is positioned at the bottom of the unit, next to the condensate drain.If you want to clean the trap, first remove the metal wire clip that holds it in place under the bottom of your cabinet and then lift the cup from the bottom of the trap.When you replace the trap, make sure that the o-ring is properly secured in its position.Waterways should be flushed.Flush solutions are circulated through the heat exchangers of water heaters and the DHW side of combi-boilers using a pump, which circulates the flush solution via the heat exchangers.
The quality of the boiler water should be checked, and heat exchangers should be cleansed if they are essential.When bringing the unit back into service, make sure everything is working properly, including the gas pressure.Further information on maintenance methods for your Navien units may be found in the operating handbook, which you can download here.

Tankless Water Heater Maintenance
Tankless hot water heaters are ideal for consumers who wish to save on energy costs while still having access to hot water on demand.The fact that they are small in size means that they are soon becoming the most popular choice for water heaters in both residential and commercial settings.If you have a tankless hot water heater, it is critical that you do regular water heater maintenance on it.Maintaining your water heater on a regular basis might extend its lifespan to more than twenty years.It is recommended that you have your hot water heater serviced at least once a year to avoid any problems.Tankless Hot Water Heater Maintenance should be performed twice a year if you live in a region with hard water or if you have the water temperature set to a high setting on your tankless water heater.
The heater’s components will function more efficiently if all of the components are properly maintained.Several tasks will need to be completed as part of the routine maintenance.
Flushing the System
At the very least, the hot water heater should be cleansed once a year.Minerals accumulate within the water heater throughout the course of the year.If you have a hard water source, the scale may accumulate more quickly.Mineral buildups in your unit’s heat exchanger might cause it to malfunction.Because of the potential failure of the tank’s efficiency, you may find yourself with an increased energy cost each month.By failing to clean your tankless hot water heater on a regular basis, you might significantly reduce its life expectancy.
Unfortunately, damage caused by mineral build-up will not be covered by your warranty policy.Flushing will eliminate all of the mineral build-up that has accumulated.Creating a vinegar water mixture, as well as having two lengths of hose and a sump pump, will allow you to flush the tank effectively.Make sure you switch off the electricity to your hot water heater completely.Turn off the water supply to the pump and then connect the hoses to the pump.Using the sump pump, you will be able to force the vinegar water into the heater, which will save time.
After you have cleansed the machine with the vinegar water, you will want to flush it with plain water to remove the vinegar smell.You can find detailed instructions on how to do this in your hot water heater’s user manual, or you can purchase a descaling package that includes the necessary instructions.If this sounds like an overwhelming process, or if you are concerned that you could make a mistake, you should hire a skilled plumber to do Tankless Water Heater Maintenance.They will be able to cleanse the system and examine the water heater to verify that there is nothing wrong with it before completing the repair.
Cleaning the Air Filter
An air filter is installed in your tankless water heater, and it will need to be cleaned on a regular basis.Remove the filter from the water heater and clean it well.After that, you’ll want to scrub it down with a soft brush and a soap and water solution to clean it.Make certain that it is well cleaned in order to maintain optimal ventilation.After thoroughly rinsing it, allow it to dry fully before reinstalling it in the water heater.
Cleaning the Water Filter
It is critical that you do not overlook the water filter while doing water heater maintenance on your unit.The majority of tankless water heaters are equipped with a screen that helps to collect any silt that may enter the system.You will need to remove these particles from your water heater on a regular basis in order to keep it operating at optimal performance.If sediment builds up in your hot water heater, it can significantly impair its ability to perform properly.The hot water heater’s water supply must be shut down before you can remove the filter from the system.Remove the filter and thoroughly clean it.
It is possible to clean it with warm soapy water or by wiping it down with a towel If you are unable to locate your water filter, consult your user handbook to identify where it is located.
Cleaning the Tank
Occasionally wiping down the outside of the tank is advisable to ensure that no dust or dirt accumulates on it.Make sure to turn off the electricity and water supplies before you begin.Using a damp cloth, wipe off the tank and the surrounding area.It is possible for a buildup of dust and debris to get inside the water heater, which can create problems.Tankless Water Heater Maintenance should be performed on a regular basis to guarantee that your unit is operating as it should.When performing heater maintenance, make sure to inspect all of the other components of the heater.
Make sure that the heating elements, valves, and pipelines are in good condition and that they are operating properly.Look for any leaks, corrosion, or anything else that appears to be wrong.If you notice anything that is incorrect, please report it so that it can be corrected as quickly as possible.The longer you let a problem to fester, the worse it can develop and the more expensive it can become.Whether you are experiencing problems with your tankless hot water heater or you want to hire someone to perform all of your water heater maintenance, contact the Original Plumber right now.Tankless hot water heaters are their specialty, and they have years of expertise with them.
They can ensure that yours performs well and lasts for twenty or more years.
How Often Do Tankless Water Heaters Need Maintenance?
It is recommended that tankless water heaters are serviced by a professional at least once a year. However, if you have a water heater that leaks, you may need to have it repaired twice a year.
- The water in the region where you reside is hard.
- The temperature of your water heater is set at a high setting
The reasons for tankless water heater maintenance will be discussed in greater depth later, but for now, just know that they are important. But first, let’s take a short look at how tankless water heaters function in general.
How tankless water heaters work
Tankless water heaters do not have a storage tank to store water.It is instead the case that they heat the water as it enters your home through the cold water line.Consequently, when you turn on your hot water faucet, you are effectively activating the tankless water heater.In contrast to traditional water heaters, tankless water heaters heat water by the use of heating components, which are also known as a heat exchanger.The heat exchanger is fueled by either natural gas (which is the most popular) or electricity.Having provided a quick description of how tankless water heaters operate, let us now look at why they require maintenance…
Why tankless water heaters need maintenance
Tankless water heaters have a lifespan of 20 years or more, but only if they are maintained properly.Unfortunately, as compared to traditional tank water heaters, tankless water heaters are sometimes misrepresented as ″low-maintenance″ technologies.However, this is not the case.When it comes to how much maintenance each unit requires, there isn’t much of a difference between the two units.The reason behind this is as follows: Both types of water heaters are affected by hard water.Hard water refers to water that has a high concentration of minerals, usually calcium and magnesium, in your local location.
In a tankless water heater, these minerals can accumulate within the heat exchanger, eventually clogging the passageways and preventing water from flowing through them properly.As a result, your water heater is forced to work extra in order to heat your water.Over time, this will reduce the lifespan of your water heater and cause your energy expenses to rise (water heater has to work longer, using more energy to heat the water).Furthermore, this mineral deposit on the heat exchanger has the potential to cause irreversible damage, necessitating the replacement of the heat exchanger or the replacement of the complete unit.It is not covered under the manufacturer’s guarantee if this sort of damage occurs.At the time of a routine maintenance visit, a professional will descale, also known as delime, your tankless water heater to ensure that there is no buildup of sediment around the heating components.
At the very least, you should have your water heater descaled once a year by a professional.Nonetheless, there are two unique cases in which you may require maintenance more frequently than once a year:
You may need maintenance more than once a year IF…
1: The area you live in has really hard water
There is some level of mineral content in the water that enters your water heater, no matter where you reside.However, in some parts of the nation, the water is more difficult to drink (meaning it has more minerals in it).Your tankless water heater may require descalement twice a year if you reside in a hard water location.This will help prevent damage to the heat exchanger in your heater.Map of hard water in the United States.Source: To determine whether your location has a high or low concentration of hard water, look at the hard water map shown above.
Here in Phoenix, Arizona, the water is quite hard.Continue reading our article ″Why Arizona’s Hard Water Secretly Makes Your Life Harder (And What You Can Do About It)″ to discover more about hard water.
2: Your tankless water heater is set to a high temperature
If the temperature of your water heater is set too high, you run the risk of scale building, which is especially dangerous if you reside in an area with hard water.As you may be aware, heat has the ability to cause many substances to dissolve more quickly.As a result, the higher the temperature of your water heater, the faster limescale accumulates around the heating components.So, here’s what you should do: Check the temperature setting on your tankless water heater’s thermostat to see what it is currently set at.Is the temperature on your thermostat higher than 120 degrees Fahrenheit?After that, it’s time to call in a professional to do routine maintenance on your tankless water heater and remove mineral buildup from the heat exchanger.

Common Questions We Have Answers To!
What is a tankless water heater?
Return to the top of the page A tankless hot water heater, also known as an on-demand water heater or an instant hot water heater, provides hot water on demand. They do not require the use of a storage tank since they heat the water as it travels through the device.
Why install a tankless water heater?
Tankless hot water heaters provide clients with a limitless supply of hot water at a reasonable cost. A tankless hot water heater should be installed by a registered professional plumber so that you and your family may take back-to-back showers without ever running out of hot water!
Do tankless water heaters save money?
Yes! Tankless water heaters are more cost-effective in the long term than traditional water heaters. A tankless water heater’s base price may be more than the price of a regular hot water tank, but these water heaters can be up to 34 percent more energy efficient than a traditional hot water tank and can last more than twice as long as a traditional hot water tank.
Tankless gas water heater or tankless electric water heater – which one?
Return to the top of the page This is one of the most often asked questions when it comes to water heaters. People are sometimes forced to choose between natural gas and electricity. If, on the other hand, you are given the option, there are certain things to consider.

What does it mean to winterize a tankless water heater?
Tankless water heaters must be winterized in order to function properly in cold weather.Due to the fact that most manufacturers do not cover damage caused by freezing under their warranties, they may require a little additional attention during the colder months.Learn why winterizing your tankless water heater is so important, as well as how to get your tankless water heater ready for the winter, by reading this article.
What does flushing a tankless water heater mean?
Flushing a tankless water heater is simply the process of cleaning it out using a descaling chemical, which eliminates any sediment or buildup that has accumulated.
What happens if I don’t flush out my tankless water heater?
Mineral deposits may form over time. This might result in a clog within the unit, which could prevent regular heating activity from taking place. Your hot water might also vary, causing the system to overheat and reduce its overall efficiency.
What are the benefits of flushing out a tankless water heater?
- Reduces the likelihood of clogging: Tankless water heaters can accumulate mineral backing, which can be flushed out using a descaling chemical to reduce the likelihood of clogging
- Noise reduction: If your tankless water heater is creating noise, it is likely that there is a buildup of sediment within the tank. If the noise goes away on its own, it is possible that the accumulation has become so hardened that water is no longer able to travel through it efficiently.
- Acceleration of the heating process: The greater the amount of buildup in the tankless water heater, the longer it will take for the heat to move. Flushing your tankless water heater on a regular basis might help it operate at peak efficiency.
- Equipment lifespan: By flushing out the tankless water heater with a descaling solution, you are extending the life of the tankless water heater.
- Cost: If your tankless water heater is clogged, it makes it more difficult for the water to move through, increasing the amount of energy required to create hot water, resulting in higher costs! Flushing on a regular basis boosts water flow and has the potential to save expenditures dramatically.
How often should I have my tankless water heater flushed out?
Tankless water heaters should be cleaned out once per year to two years, depending on their age.
Why should I have my tankless water heater flushed out so regularly?
Tankless water heaters need to be cleaned out more frequently in the areas near Rochester, NY that are supplied by the Monroe County Water Authority since the water is somewhat hard.
What is hard water and how does it impact my tankless water heater?
Water hardness is a measure of the amount of minerals present in a body of water.Monroe County’s water is regarded to be somewhat hard by most standards.In one gallon of hard water, it comprises between 5.6 and 7.6 grains of calcium carbonate.Homeowners in Rochester, NY and Monroe County do not require a water softener; nonetheless, flushing out your tankless water heater with a descaling solution is extremely vital owing to the mild hardness of the water in Rochester and Monroe.

Navien Tankless Water Heater Review: Products, Problems & Comparisons
Tankless water heaters have seen significant advancements in recent years.When compared to tank-style water heaters, tankless water heaters are more widely available, provide greater cost savings, and have a lower physical and carbon impact.If you are in the market for a tankless water heater, Navien is one of the newest names on the block.If you are considering a tankless water heater, it is worth your time to check into it.For the North American market, Navien is a relatively new entrant.Navien is a leading brand in tankless water heater technology, competing with other well-known brands such as Rinnai and Rheem.
When it comes to developing energy-efficient, ecologically friendly goods and lowering CO2 emissions, Navien has won international recognition for its work.Navien has a shorter history than the majority of other water heater firms, yet they are the most rapidly expanding.Let’s look into Navien a bit more closely.
A Brief History of Navien Tankless Water Heaters
Navien was originally known as KyungDong Navien, or KD Navien, when it was established in Seoul, South Korea, in 1978.In 1988, KD Navien became the first business in Asia to design and manufacture a condensing boiler that was both extremely efficient and ecologically benign.The firm soon extended into other countries.Navien sells HVAC equipment to more than 30 nations throughout the world, including the United States.In 2006, the firm moved to North America, where it quickly grew to become the leading maker of condensing gas water heaters in the region.North American Branch is based in Irvine, California, and serves customers across the world.
It wasn’t until lately that Navien goods began to be produced in other countries.The firm plans to expand to the east coast of the United States in the near future.Navien was one of the first boiler manufacturers to embrace the European standard for all boilers, assuring that their products are of the highest possible quality in any area where they are marketed.They have maintained their position as leaders in the design and manufacture of environmentally friendly products.The Navien HYBRIGEN SE is an example of such a vehicle.Navien’s website describes the technology as ″next generation green technology capable of fixing the global power supply dilemma while simultaneously lowering fossil fuel usage and greenhouse gas emissions.″ (1) A second point of emphasis for Navien is making certain that all of their water heaters are installed and serviced by competent specialists.
This is accomplished via the use of three state-of-the-art training facilities located in Irvine, California; Moorestown, New Jersey and Woodbridge, Ontario.(2)
How Reliable Are Navien Tankless Water Heaters?
Navian water heaters have the greatest efficiency rating available on the market, as well as LEED and Energy Star® certifications, placing them among the greenest water heaters available on the market.These certifications demonstrate that Navien water heaters have longer lifespans, consume less energy, and have a smaller carbon footprint than water heaters manufactured by other companies in the industry.Tankless water heaters from Navien are available in two different models: condensing and non-condensing.Since the water heater does not have to heat a tank of stored water, one of the advantages of a tankless water heater is its capacity to swiftly heat water on demand.Steam is produced extremely fast as a result of the tremendous heat.Once the steam has cooled, it condenses back into water, completing the cycle.
The acidity of the condensed water has increased significantly, and it might cause damage to the water heater and pipelines.A condensing tankless water heater absorbs the additional heat from the water it heats from inside.Before it is discharged outdoors, the acidic water is neutralized, either by filtering or diluting it to remove the acidity.A non-condensing tankless water heater sends the steam outdoors, where it may cool without condensing inside the heater tank.A few of the unique characteristics of Navien’s tankless water heaters, both condensing and noncondensing, include:NaviTechTM — Dual stainless steel heat exchangers and burners.
Integrated ComfortFlow® Built-In Recirculation System — This system has an integrated insulated buffer tank and recirculation pump that may be used with existing supply lines, eliminating the need for additional pumps or controls.
EZNavTM Intuitive Control Panel — This control panel simplifies the process of configuring and troubleshooting the system by displaying temperature, water flow rate, and the state of the cascade.
When a dedicated return line is not available, the NaviCircTM is an optional recirculation valve for residential hot water that may be used instead.
H2AirTM- An optional package for use with a space heating and domestic hot water system in conjunction.The system includes a pump that pumps hot water to a heat exchanger that looks similar to a radiator and is positioned in a furnace or air handler.The blower in the device draws warm air over the heat exchanger and distributes it via the ductwork, eliminating the need to acquire an extra circulator for the heating system, which would otherwise be required.
A Wi-Fi remote control system, NaviLinkTM, is available as an optional feature. You can control the temperature of your water heater, view use data, and check on the health of your water heater all from your smartphone.
HotButtonTM – An optional hot water activation mechanism that may be activated by pressing a button. The boiler is responsible for heating and storing water inside the distribution system. You can turn on the recirculation pump and the burner with the touch of a button, without ever having to open the faucet.
How Long Do Navien Tankless Water Heaters Last?
As a result of its longer lifespan, tankless water heaters are becoming increasingly popular.However, Navien’s unique and copyrighted features are designed to ensure that their water heaters last for decades.It is reasonable to anticipate a Navien tankless water heater lasting 15 to 20 years, or even longer with regular maintenance.One of the primary advantages of using a tankless water heater is that it warms water just when it is needed, as opposed to a tank-style water heater, which continually heats an entire storage tank.While this in and of itself helps to extend the life of a tankless water heater, there are a number of things that we as homeowners can do to further increase its lifespan – and save money in the long run.Listed below are four methods for keeping tabs on the health of your tankless water heater:
- Whether your water is clear or hazy, rusty, or even including sediment, the quality of your water is important to consider. In order to determine if there are any difficulties with the water supply, you need first contact your local municipal water supplier and inquire. A water purification system may be required if this is the problem.
- The smell or flavor of the water – Does your water have a metallic odor or taste, or does it have another strange smell or taste? This might be due to the presence of iron in the water heater, which renders the water unfit for drinking purposes. Your plumber will be able to assist you in determining if the problem is with the water or with the tank.
- It is normal to hear some noise from your tankless water heater, but if you start to hear any, it might be a warning that sediment is accumulating in the tank. The sediment will need to be drained out in order to prevent it from building up further, and you will then need to replace the complete water heater.
- Pressure change – When there is a shortage of hot water and low pressure, it is a warning that something is really wrong with the system. Call your plumber as soon as possible
Where Are Navien Tankless Water Heaters Manufactured?
Navien tankless water heaters are made in Seoul, South Korea, by Navien Corporation.On the other hand, Navien announced in February 2020 that it will be establishing its first production facility in the United States of America.Virginia’s James City County will serve as the site for the production and assembly operations.Navien will invest $77.5 million in the project, which will result in the creation of around 180 new jobs in the city.(3)Initially, the facility will be operated solely as a distribution hub, with production operations beginning in 2023 after that.By 2026, Navien plans to more than double the size of its present 300,000-square-foot plant to over 900,000 square feet.
It will be possible to send goods to eastern markets more quickly by utilizing the Port of Virginia, which is an East Coast facility, while keeping present supplies into California in balance.
Cost of Top Navien Tankless Water Heater Models?
Navien tankless water heaters are available for purchase for between $800 and $2,000 for the device alone.Given that you can only acquire Navien goods from an authorized dealer at this time, you will need to budget for the cost of hiring a plumber, as well as any service fees and installation costs.The type of water heater you choose is the most important aspect in deciding pricing.Navien is well known for their tankless water heaters, which are available in two varieties: condensing and non-condensing models.However, the firm has grown to incorporate a combi-boiler series as part of its product line.These heaters will not only heat your water, but they will also heat your entire home.
Obviously, the price tag for this sort of heating system will be far more than that of a typical tankless water heating system.It will be less expensive to purchase a non-condensing tankless water heater initially, but it will be more expensive to install.Because of the complexity and cost of the venting system, which must be made of non-corrosive materials, this type of tank is not recommended.It is possible that interior components will be less expensive since they do not have to endure the corrosive nature of the effluent.Installing a condensing tankless water heater will be less expensive than purchasing one, but the latter will be more expensive than the former.Because it neutralizes the heat and gases, the condensing unit will not necessitate the installation of an expensive ventilation system.
The interior components, on the other hand, will be more expensive since they would have to survive the corrosive effluent.Additional factors that might influence the cost of installation include whether or not a new gas line is required, as well as whether or not a recirculating water line is required.Optional add-on features will also increase the cost of the initial purchase.Estimates for these properties are provided in the table below.A Navien tankless water heater will initially cost more than other tankless water heaters, but you will save money in the long term since it is more energy efficient.

Navien provides the most comprehensive warranties available on the market.All Navien water heaters are backed by a limited warranty that covers labor, parts, and the heat exchanger, among other things.The warranty durations for Navien products begin on the date of installation and include a one-year labor guarantee, a three- to five-year components warranty, and a five- to fifteen-year heat exchanger warranty, depending on the product.According to Navien’s website, you will be ineligible for their warranties if any of the following events occurs.The water heater was acquired and/or installed by someone other than a Navien provider or distributor who was authorized to do so.

How Does Navien Compare To Similar Brands?
Although Navien does not have the same extensive history as other businesses, it has demonstrated that it is deserving of being featured with well-known names like as Rheem and Rinnai, among others.Navien has earned a reputation for manufacturing tankless water heaters that have shown to be of excellent quality and constructed to last for decades time and time again.In addition, Navien distinguishes itself by developing and producing energy-efficient, ecologically friendly goods that make use of cutting-edge technology.Which firm you choose is determined by your preferences for what you are searching for in a company and product.Here is a quick comparison of tankless water heaters from Rheem and Rinnai to assist you in making your decision.
Rinnai is a Japanese company that manufactures and sells gas appliances.The company was formed in 1920.For the duration of World War II, Rinnai temporarily halted their gas appliance production in order to manufacture airplane parts for the war effort.By the 1950s, Rinnai had established a presence in Tokyo and had rapidly moved into other nations.Rinnai is now present in more than 20 countries.The American branch, which was established in 1974 and has its headquarters in Peachtree City, Georgia, was established in 1974.
(5) Circ-LogicTM technology is included in the majority of Rinnai tankless water heaters.In this approach, hot water is pumped back through the pipes at predetermined intervals, rather than the other way around, so that you have hot water when you need it.It is via this technology that they are able to make their water heaters more energy and cost-effective.Rinnai’s tankless water heaters are also fitted with the control°rTM Wi-Fi module, which allows for remote monitoring and control.This module enables you to monitor warnings remotely, control schedules, alter the temperature, and schedule maintenance using your smartphone or other smart devices like as Amazon Alexa or Google Home.
However, even though Rheem was founded in 1925 in Emeryville, California, the company was not well-known at the time for their water heaters.The company’s products included steel drums, transport containers, and even musical instruments, according to the website.It wasn’t until the early 1900s that Rheem began manufacturing water heaters, boilers, and tanks for the general public.In addition, Rheem took a brief hiatus from commercial work during World War II to assist with the war effort.By the end of the 1960s, Rheem had expanded to cover 19 different nations throughout the world.Paloma Industries of Nagoya, Japan, a leading maker of gas appliances, acquired Rheem for an undisclosed sum.
As of today, Rheem produces a range of tankless water heaters that are divided into three categories: tankless condensing, tankless mid-efficiency, and tankless electric.The Performance Line is more suited for home applications and may be found at a variety of big-box retail outlets.Rheem water heaters are energy-efficient, include smart technology for simplicity of use, and are equipped with recirculation pumps to decrease the amount of time spent waiting for hot water to come out of the faucet.The results of these comparisons demonstrate that all three firms are deserving of your consideration.
