This is due to the durability of the product and the availability of warranty service. Also read: “Gas boiler from Beretta - simple, reliable and functional”

What types of Navien wall-mounted boilers are there?

Made in Korea.

A company from Asia loudly declared itself and its products, so the choice of European brands was reduced. Products from a Korean company can compete with gas units from any European manufacturer. Therefore, user reviews about the Navien gas boiler are only positive.

One of the most popular and reliable is the double-circuit mounted boiler unit of the Ace line. Such devices may have an open or closed combustion chamber. The functional component of the device is durable, which is noted by users and specialists. At the same time, the price of the Navien mounted boiler is much lower than the equipment offered by European brands.

The line is represented by several devices:

• Navien Ace ATMO;
• Navien Ace-20k;
• Navien Ace TURBO.

The last model is worth considering first. This boiler is available in two variations - Korea and Coaxial. Wall-mounted equipment for the heating system has a rated power of 13-40 kW. Moreover, this indicator does not depend on the modification. The Navien gas boiler, according to reviews, is ideal for use in the climatic conditions of our country.

The equipment is characterized by its ability to operate in difficult operating conditions: pressure surges in the gas pipeline, and voltage surges in the power supply network. Even being for a long time not turned on, such a boiler will start without problems and perform its functions 100%.

Features of Navien Ace TURBO

Compact arrangement of boiler elements.

The wall-mounted double-circuit boiler is characterized by the following:

• application for heating water and heating residential buildings;
• the equipment contains a steel heat exchanger coated with anti-corrosion, which significantly reduces the cost of the equipment in comparison with boilers equipped with copper heat exchangers;
• Navien Ace gas boiler (operating instructions included with each model) is easy to use;

Wall-mounted hardware has brains. This means that the unit ensures that the coolant does not freeze in the pipelines of the heating system. Automation works in two cases. The first is when the water temperature drops to 10 degrees. At this time the time is turned on. The second situation occurs when the coolant temperature is less than 6°C. In this case, the gas burner is turned on, heating the coolant to 21 degrees.

The Navien Ace TURBO double-circuit boiler and the 16k model will operate when the voltage in the power supply network is reduced to 30%. The Navien Ace 16k instructions also indicate that the boiler will not turn off when the water pressure in the system is 0.1 bar.

Navien products have positive reviews. This is due to the long period of use and high efficiency of the unit. The equipment is characterized by high fuel and electricity savings. This is facilitated by the presence of turbocharging and an APS sensor, which monitors air pressure.

Characteristics of Navien Ace ATMO and Navien Ace 20k

The boiler is equipped with uninterruptible voltage.

The company's products include double-circuit boilers with and without turbocharging. The latter belong to the Ace ATMO line. They have the same functions as the turbocharged version. Korean gas boilers Navien Ace reviews are largely positive, which once again indicates the quality of the product.

This unit is equipped with the same chip, providing uninterrupted operation during voltage surges in the power supply network, the same as the models described above. A distinctive feature of the device is the absence of turbocharging, which ensures silent operation.

Navien Ace 20k, like other units of the Korean brand, is fully adapted to the climatic conditions of Russia. The device operates reliably at low gas and water pressure, which makes it possible to use them in multi-storey buildings. residential buildings. This expands their scope of application. Organizing the removal of combustion products can be carried out in different ways:

• by installing a horizontal (conventional) chimney;
• at separate system smoke removal;
• by mounting in a vertical position.

It is important to note that some variations of equipment from Navien support remote control using a phone or tablet.

Autonomous heating and supply hot water turn a private house into a comfortable home that provides considerable savings and does not depend on the appetites of resource suppliers.

Installing your own boiler allows you to independently regulate the heating mode, based on need and climatic conditions, and not on the average annual coolant supply schedule.

The choice of equipment in the retail chain is extensive, but finding the most successful option is quite difficult.

The cost of European boiler models is too high; the quality of domestic models often leaves much to be desired.

Let's consider one of the most good options, combining affordable cost and high quality.

Navien gas boilers are products of the South Korean industrial concern KyungDong NAVIEN.

The company specializes in the production and design of heating equipment operating on various types of fuel - liquid, solid, gas and electricity.

Navien Deluxe is a series of double-circuit wall-mounted gas boilers that replaced the discontinued Navien Ace family.

The design and set of functions have remained virtually unchanged, although some aspects have been improved and supplemented.

The units supply coolant (HC) to the heating system and at the same time provide housing hot water(DHW).

Korean developments were carried out taking into account Russian conditions and are specialized in working with unstable parameters in all areas - gas and water pressure, power fluctuations. The equipment fully complies with the norms and standards in force in the Russian Federation.

Navien boilers are equipped with a special device that compensates for voltage fluctuations in the network up to 30%.

What models are included in it?

The Deluxe series includes the following boiler models:

• Deluxe.
• Deluxe Plus.
• Deluxe Coaxial.
• Deluxe Atmo.

The first three models practically do not differ from each other, having only minor differences in the design of the chimney or the amount of gas supply.

The Atmo model is boilers with open camera combustion, which differ in the supply of air directly from the room.

All types of boilers are produced in various options by power:

• 13k (kW).
• 16k (kW).
• 20k (kW).
• 24k (kW).
• 30k (kW).
• 35k (kW).
• 40k (kW).

Some models are created on the basis of one standard size with software-limited functionality.

Thus, boilers with a power of 24 and 16 kW are of an identical design, but the 16 kW models have slightly reduced power. This gives the units a noticeable power reserve, allowing them to freely overcome load changes and external influences.

Specifications

Let's consider specifications boilers Navien Deluxe:

Some changes or additions in the values ​​of boiler parameters are possible due to improvements in the design by the manufacturer.

Advantages and disadvantages

The advantages of Navien Deluxe boilers include::

• The ability to provide hot water supply along with the organization of heating of the home.

• Possibility of using only standard components.

All features of Navien Deluxe boilers, in fact, are specific design features and can be fully compensated correct operation and service.

Device

The Navien gas double-circuit boiler heats the coolant and ensures its circulation in the system.

A gas burner, combined with a primary tubular heat exchanger, heats the OM flow, which at the outlet passes through a three-way valve.

To obtain a given temperature, a certain amount of cooled return water is mixed in, after which the coolant is sent into the system.

The combustion mode is regulated by the supply fresh air performed by the fan.

Heating of hot water produces secondary heat exchanger(lamellar). The operation of all devices is monitored by a system of sensors that signal to the control board about the occurrence of certain problems.

Where is it used?

Navien Deluxe gas double-circuit boilers are designed for heating and supplying hot water supply in private homes.

The boiler power corresponds to the area being served, which makes it easier to select the right device.

For heating industrial or public buildings the use of the Navien Deluxe series is not recommended, since the specific capabilities of the equipment in such conditions will not be fully revealed.

Often such equipment is installed in apartments, if their size allows the installation of equipment of similar power.

What's included

The Navien boiler package includes::

• Primary and secondary heat exchangers.
• Expansion tank 8 l.
• Gas heating pad, closed or open type.
• Three-way valve with electric motor.
• Fan for organizing turbocharging.
• Circulation pump.
• A sensor system connected to a control board.
• Built-in voltage stabilizer.
• Remote control.
• Housing with external connecting pipes.

Depending on the model and series, some additional components may be present. Constant development and improvement of the design contributes to the complication of old and the emergence of new elements.

User manual

Navien boilers operate automatically and require virtually no human intervention.

The only thing that is required from the owner is installation comfortable temperature OB. If liquefied gas is used as fuel, it is necessary to ensure timely replacement of cylinders.

Opportunity long work without specialized service checks is a feature of Navien equipment, which is convenient for users and relieves them of concern about the condition of the unit.

If any malfunctions occur, the corresponding error code appears on the display, the water pressure is shown by a pressure gauge, which allows you to timely detect a leak in the system.

The owner may be required to purchase and install a special filter or water softener, which will extend the life of most boiler components - the heat exchanger, pump or three-way valve. If the water supply is from your own well, installing a softener becomes a necessity.

Setting up the device yourself

To configure the boiler, set the debugging mode. Then you should adjust the gas pressure limits - minimum and maximum.

From circulation pump it is necessary to release the air by unscrewing the plug. This is done after the pressure has built up during circulation of the heating agent..

The boiler operation is configured using DIP switches.

• You can turn on automatic air removal using DIP switch No. 1, which will start circulation for 2 hours and gradually remove air automatically.
• Turning on switch No. 2 switches the system to maximum power, at which the maximum gas pressure can be adjusted.
• When switch No. 3 is turned on, the boiler is switched to forced operating mode at minimum power, at which the minimum gas pressure is adjusted.

All switching must be performed with the power supply turned off.

Setting up the boiler should be entrusted to specialists from the service center. Self-execution work is possible only if there is an urgent need and there is no warranty agreement.

Basic malfunctions and their solutions

Any faults that occur are shown on the display as a numeric code. Each of them corresponds to a specific error, i.e. a signal from a specific sensor about the failure of the corresponding node.

There may be additional codes that you should read carefully in the user manual.

Instructions for use gas boiler Navien colorfully describes the sequence of commands to control this device, which is capable of operating under conditions when competitors’ equipment simply stops.

This speaks in favor of how completely electronic system management and key principles, used to regulate the operation of the boiler. Navien, a product from a Korean manufacturer, is reliable, stable, and able to cope with frankly emergency operating conditions.

Key Product Features

The boiler is distinguished by its low price. Nevertheless, the instructions for the Navien gas boiler are very detailed, the installation of any modes is thoroughly described. Thus, one can understand how seriously the manufacturer approached communicating the main aspects of control to the average buyer. Users will have no problems setting up and using the device.

The system follows the same goal electronic control, as well as adjustments of other key parameters. To understand how versatile Navien equipment is, here’s short list his abilities to work under non-standard conditions.

1. To protect and smooth out voltage surges in the power supply network, a regulation circuit using a microprocessor chip is used. When changing parameters, the electronics maintains a mode that allows all components of the boiler to function normally. This not only extends the service life of the unit, but also eliminates some malfunctions of the Navien gas boiler, which could be caused by false alarms of the sensors. This feature electronics is very important, since the power grid voltage can fluctuate within 30% or more of the nominal voltage.
2. Possible blockages and malfunctions of Navien wall-mounted gas boilers caused by non-standard water pressure are minimized. The design is thought out in such a way that it works reliably even when the indicator drops to 0.1 bar. This makes the device ideal for installation on upper floors apartment buildings where there is a periodic drop in water pressure in the cold water supply circuit.
3. Malfunctions associated with non-standard gas pressure indicators are successfully neutralized by the Navien gas boiler device. The nozzles, protection systems, and supply provision are such that the unit operates confidently even with a critical drop in supply pressure to 4 mbar. This is an extremely low figure and cannot be used by most modern electronically controlled systems.
4. According to the instructions for the Navien gas wall-mounted boiler, freezing of the heating system will be prevented even if the gas supply is stopped. To prevent emergency mode when the coolant temperature drops below 5 degrees Celsius and the burner cannot be ignited, the built-in pump begins forced continuous circulation of water in the system, which prevents it from freezing.
5. Since all systems of this brand are equipped with a double heat exchanger for separate heating of hot water and heating fluid, priority modes can be flexibly configured. It is even possible to set the conditions for preheating water for hot water supply. The electronics allow for very convenient settings, and the instructions for the Navien double-circuit gas boiler will clearly show the user how to do this.

The equipment of this company provides an advanced control principle. The remote control from which parameters and modes are configured is remote. It is also used as an external thermostat sensor to measure and maintain room temperature.

The engineering features of Navien products, which set high parameters for its quality, and also confirm the opinion of some experts about the unlimited service life of boilers, include the following facts.

1. Separate heat exchangers from of stainless steel, not subject to corrosion, providing high heat transfer.
2. System automatic maintenance pressure in the heating system. If the pressure is exceeded, the water is drained, and if the pressure is insufficient, it is taken from the cold water supply system, according to the instructions for the Navien gas boiler of a specific model. A pressure gauge is used to control pressure.
3. The incoming water passes through the filter and is effectively purified.
4. Personal drain channels are provided to get rid of water in the coils if forced circulation is not possible.
5. Electronics control the gas supply so precisely that the water temperature in the system can be set with an accuracy of 0.1°C.
6. IN summer period time, you can change the operating mode to provide only the demand for . This is easy to do both according to the instructions for floor-standing gas boilers Navien, and according to the documentation for other models.
7. To save fuel, there is a customizable “Away” mode, when the boiler can maintain a minimum temperature in the room.

Key system shortcomings

With all the functionality, crammed with electronics, convenience and ignoring difficult working conditions, Navien gas boilers are not without some drawbacks. Users often encounter cases where the device refuses to work because the electronics indicate a critical error. This occurs for various reasons, including those related to the high sensitivity of the sensors. Let's look at two of the most frequently repeated mistakes.
Smoke removal
If there are problems with the removal of combustion products, fault code 10 of Navien gas boilers appears. According to the user manual, there may be several reasons for this signal:

• failure of the turbine (engine or due to a problem in the scroll mechanism);
• incorrect connection of pressure sensor tubes;
• chimney blockage;
• large length of the pipe leading out (the maximum length is indicated in the instructions);
• gusts of wind.

Most often, users experience the following picture:

• chimney of permissible length;
• not clogged;
• The pressure sensor tubes are in order, since no intervention was made to the structure.

Many people get upset, thinking that there are problems with the turbine. However, oddly enough, most often the reason is strong wind outside. According to the manufacturer, it is recommended to install boilers with the chimney exiting on the leeward side of the building.

As a result of the fact that the wind blows differently at different times of the year, heating systems may refuse to work based on a sensor signal, indicating a malfunction 10. One of the solution methods is to remake the chimney.

Since this cannot be done quickly, you can open the device case and disconnect the air supply pipe. The turbine will begin to take it out of the room, the boiler will start working. The solution is temporary, but it works.

Flame sensor failure

Malfunction error 03 of Navien gas boilers is caused by poor fuel quality. The mechanics of the problem are as follows:

• gas is supplied;
• the pressure in the line is sufficient so that the sensors do not raise an alarm;
• When igniting, the sensor electrode does not warm up sufficiently, since the distribution of the temperature zones of the flame is disrupted.

The problem is solved exclusively by the selection method. The first thing to check is the cleanliness of the gas supply nozzles. If they are clean and fuel is supplied, the second step is to select the position of the sensor electrode. It must be in the hot phase of the flame for the signal to be correctly recognized.

This error is rare where gas is supplied good quality, since the products of this company do an excellent job with any pressure indicators. But in regions with low quality gas treatment, fault code 03 is quite common. Sometimes it is necessary to change the position of the sensor electrode several times during one heating season.

In general, the manufacturer's heating systems represent a fairly cheap, technologically equipped solution, ideal for coping with non-standard conditions work. They can be extremely useful because they are very reliable and durable. All components are produced by enterprises in Korea and Japan, the assembly is of high quality, the boilers meet all international standards.

Like any complex device, Navien boilers are not without problems. However, in most cases the user does not encounter any problems when using equipment from this manufacturer.

If we consider the turnover of heating devices on the domestic market, we can see that consumers give preference to European equipment. However, the Korean Navien mounted boiler, the price of which is lower than its Western counterparts, occupies the top position among other heating devices.

For ease of installation, the connecting tubes are located on both sides of the device, which greatly simplifies the piping and installation of the Navien Ace gas boiler.

Fuel preheating (KR series)

At low temperatures, the viscosity of the fuel increases, resulting in a waxing effect, which significantly impairs the flammability of diesel fuel and the operation of the Navien gas boiler becomes unstable. This feature of operation is relevant for regions with harsh climates, therefore arctic and winter diesel fuels were created for these conditions.

Gas devices Navien work on any diesel fuel Russian production However, the cost of winter or arctic diesel fuel is much higher than that of summer diesel fuel, and the use of summer fuel is impossible at low temperatures without preheating it.

The heating element, which is built into the burner of the Navien gas unit, preheats it before supplying fuel to the nozzle, resulting in high-quality fuel atomization and uninterrupted ignition. Due to preheating, Navien Ace gas boilers have possibility of using inexpensive summer diesel fuel, which leads to significant savings.

The Navien boiler is high-quality South Korean heating equipment. The company produces modern gas boilers. These products quickly gained the trust of consumers and became a regular participant in the domestic market, significantly expanding the ability of buyers to choose the ideal boiler for themselves.

Photo of the Navien boiler

Wall-mounted and floor-standing boilers from Navien have a number of features that set them apart from their competitors.

1. System for working during power surges. Navien gas boiler models are distinguished by the presence of technical components that allow the equipment to operate even with differences in the power supply reaching 30 percent. This is a guarantee that your wall-mounted boilers will not require repairs if problems arise with the electricity in your home. And such situations are not uncommon for us.
2. Ability to operate at low water system pressure. Problems with pressure in the water supply are less common, but even if they occur, the boiler will function normally and provide heat to the entire house.
3. Not one heat exchanger, but two. All wall-mounted models of Navien boilers have not one heat exchanger, but a pair. Each heat exchanger is made of stainless steel, which is reliable, efficient and corrosion resistant. This design with a pair of heat exchangers increases the boiler’s resistance to water contamination and scale, and provides affordable repairs. The price of the Navien boilers themselves is quite attractive - from 30 thousand rubles. There are also more expensive, efficient models that can provide heat to large rooms.
4. Turbocharging Each floor-standing and wall-mounted boiler from the South Korean company Navien is equipped with a turbocharger - an air supply system. This increases the efficiency of the boiler device. The air supply pressure is regulated automatically. As a result, better heating of the house is provided with less fuel.

Advantages

We talked to you about the design features of Navien boilers. That's four objective reasons pay close attention to such models as the Navien Ace and Deluxe, Prime boilers.

If we put Navien boilers on a par with competitors presented on the domestic market in approximately the same price category, the South Korean manufacturer will demonstrate a number of obvious advantages:

• High level of quality and reliability of automation. Errors for such boilers are rare and can only be caused by system failures or improper control by the user. But if errors occur on Deluxe, Prime or Ace models, fixing them is quite simple. Most of the work is done by automation. Errors are easy to read, the reasons for their occurrence are determined according to the manufacturer’s instructions;
• Availability of SMPT protection chips. With their help, gas boiler equipment works perfectly under conditions of an unstable electrical network. You all know how often problems arise with the electrical network in our homes. Many boilers are not able to cope with such fluctuations; they constantly produce errors and fail. With Navien boilers, such situations are minimized;
• Adaptation of Navien boilers to operating conditions in domestic realities. We are talking about unstable pressure in the gas pipeline and problems with water pressure in the water supply. A Navien boiler of the Prime, Deluxe or Ace models copes well with such conditions when the gas pressure drops to 4 mbar and the water pressure to 0.1 mbar;
• Real Korean assembly. Unlike many products that have European or other designations on their bodies, Navien boilers are actually assembled in Korea, and not somewhere in China in order to reduce the cost of assembly. It is no secret that many foreign companies are setting up production in the Middle Kingdom. And they pass off the equipment as European, for example;
• Remote controls. Navien boilers are equipped with special convenient remote controls, with which the user can remotely change the operating modes of their boiler equipment.

Range

The assortment of the South Korean company Navien is constantly expanding, which allows customers to purchase gas boilers that are optimally suited in all respects.

Therefore, tell us about all the representatives model range impossible. Instead, we will look at Navien equipment, which can be divided into three broad categories.

1. Wall models. Wall-mounted boilers have a double heat exchanger and are labeled as Ace, Deluxe. Deluxe is dual-circuit models, which have a wide power range from 13 to 40 kW. All Deluxe series boilers are turbocharged. Turbocharged Deluxe equipment can have a coaxial or separate chimney. In addition to Deluxe, the Ace series of wall models is in great demand. The Ace series is divided into Turbo and Atmo. The difference between them is that Turbos are fully adapted for operation in conditions of non-steel gas and electricity supply to the boiler. An additional advantage of Ace Turbo is frost protection and burner turbocharging. If we talk about Atmo, then this is a classic gas boiler that perfectly provides heating for a private home. Atmo has everything strengths Turbo, except for burner turbocharging.
2. Floor-standing boilers from Navien. If wall-mounted models do not suit you for one reason or another, floor-standing models have earned excellent reviews. They are used for heating and hot water supply of private houses. To the distinctive features floor models Navien boilers include their compact size, ease of operation and convenient installation. Each boiler is supplied with instructions, according to which even a novice in such matters can carry out the installation. Wall-mounted models are somewhat easier to install, although there are no problems with them. A double heat exchanger significantly increases the efficiency of heat generation in a gas boiler.
3. Condensation. Deluxe, Ace and other models of the Navien company recently received a serious competitor in the form of South Korean condensing boilers. They are marked NCN. Their distinctive feature is increased power, the range of which is 19.6-37.9 kW. These boilers use fuel efficiently, using less fuel but providing higher quality heating. The efficiency of Navien condensing-type boilers reaches 108 percent. This was made possible by using the heat that is released when steam condenses. This way, consumers save money on gas bills, but heat their own homes more efficiently. The heat exchanger here is slightly different. Its design is unique and is distinguished by the presence of a system for preliminary creation of a combustible mixture. The burners are necessarily modulating, the range of operation of which is amazing.

By choosing boilers from the Navien company from the Deluxe, Ace or other ranges, you are buying quality and reliability. This is one of the few cases where the manufacturer does not demand more just for the brand. The high level of Navien boilers is beyond doubt.

Mounted gas boiler " Navien Deluxe 24k"is a bestseller in Russia recent years. And this is understandable; the optimal price-quality ratio, good technical characteristics and reviews have made this model very popular among domestic buyers.
