Gas wall-mounted boiler NAVIEN

When the consumer is faced with a choice gas boiler for heating, you have to take into account a large number of criteria to ensure its efficient and economical operation. In this regard, domestic and foreign units should be divided. Unfortunately, not all “foreigners” can withstand the difficult Russian operating conditions - low quality coolant, changes in gas and water pressure, periodic power outages. True, many foreign analogues today have already been adapted to Russian conditions. For example, the famous South Korean model line “ Navien Ace» with instructions, which stipulate that these boilers can be used in Russia.

The Navien Ace brand is wall option double-circuit boiler. This model refers to Navien equipment with an open combustion chamber and natural removal of combustion products. What is included in the boiler design?

Boiler equipment

The design of the unit includes:

• Two heat exchangers from of stainless steel, which guarantees their long and reliable operation.
• Remote display of the control unit, which is completely Russified. For the Russian consumer this is a very important condition.
• Built-in circulation pump.
• Expansion tank.
• Safety valve.
• Air vent operating in automatic mode.
• A bypass valve, which is also adjusted automatically.
• Traction sensor.
• Electric current stabilizer.
• Remote control, which is convenient in terms of maintenance.

The South Korean boiler navien ace is fully equipped with Japanese automation. In this case, the manufacturer gives guarantee period operation 2 years. This is a fairly compact device with excellent technical characteristics. The operating instructions for Navien boilers make it easy to understand all the intricacies of setting up the device, modes and temperature ranges.

Classification

Gas boilers"Navien Ace" are divided into two categories:

1. Ace ATMO.
2. Ace TURBO.

The first unit is a simple and traditional boiler with an open combustion chamber, which uses atmospheric exhaust of combustion products. The second is more advanced and has a turbocharged burner. This allows you to efficiently supply gas and burn it when the supply is unstable, which is associated with pressure surges. In addition, the second option is equipped with a special SMPS control system, which is based on highly sensitive chips. They are responsible for monitoring and regulating gas combustion processes. In all other respects, both options are no different from each other.

Both models can be classified as universal equipment. Adapted to difficult operating conditions, they are considered one of the most economical heating devices that are present on the market today. Russian market. An important component of the design is remote management. This is very convenient when you can set modes and indicators from a distance, quickly making adjustments.

But what’s surprising is that Navien gas boilers can operate not only in automatic mode, but also in manual mode. This is especially convenient when the temperature outside the window changes sharply. Manual installation allows you to more accurately set parameters and indicators, which eliminates the smallest errors during the operation of heating equipment.

Navien ace gas boilers can be called universal units. They operate on natural gas or liquefied bottled gas. To switch from one type of gas to another, you only need to change the burner. No other changes are required.

What to pay attention to during installation?

Steel gas boiler Navien Ace

Since instructions are included with the equipment, there are no problems with installing and connecting the device. Doing it yourself is not a problem. Even a non-professional can understand the instructions. Moreover, it is written in Russian.

The only thing that experts ask you to pay attention to is the method of removal carbon monoxide. They can be discharged through a regular atmospheric chimney connected to the smoke exhaust system of the house or installed as a separate structure. But if you are not satisfied with any option, you can make a coaxial chimney. Its installation is several times simpler. But keep in mind that coaxial structures are used only when the heated area of ​​the house does not exceed 110 m². They can be installed with boilers whose power does not exceed 11 kW.

Conclusion on the topic

Gas boilers "Navien Ace" are high-quality heating equipment with excellent technical and performance characteristics. Adapted to the difficult Russian operating conditions, they have firmly taken one of the leading positions in the Russian heating equipment market. Their popularity is not falling, which means there is a high probability that other models will always be in demand.

It is difficult to choose a suitable gas boiler due to the huge range of models for sale. Even within the same manufacturer, the number of units can be overwhelming. In order to make the choice easier, you should take a closer look at models from famous developers. For example, great solution will be the Navien gas boiler, created by the Korean company of the same name. Let's see what kind of boilers these are, what makes them remarkable and why consumers choose them.

Navien heating gas boilers are manufactured using the manufacturer’s own developments, which increase the efficiency of the equipment and its cost-effectiveness, as well as facilitating easier operation.

Gas boiler Navien DELUXE 24K

Alexei, 29 years

It took a long time to choose a boiler - before we settled on Navien, we read a bunch of reviews and testimonials. After numerous consultations with sellers and heating specialists, we settled on this model. The installation was carried out by the same specialists; I did not dare to do anything myself. The first winter was successful, there were no breakdowns during operation. Very convenient controls - the remote control was placed next to the sofa in the living room. You set the temperature, and the unit in the kitchen independently maintains the required mode.

Advantages:

• Compactness – compared with some other devices, in particular from Proterm. As a result, the Navien Deluxe boiler turned out to be slimmer;
• Low noise level - a couple of times in the winter we went to visit our neighbors and heard their Baksi boiler working, the fan rumbling and howling;
• Quickly achieving the set temperature is important after our long business trips, when you enter the house and want to quickly feel comfort.

Flaws:

• The absence of controls on the gas boiler itself, as is implemented in other heating units, is where the specialists from Navien made a mistake;
• Sometimes the DHW performance is not enough - two open taps lead to a drop in temperature.

An excellent device with minor imperfections (like everyone else, probably).

Gas boiler Navien DELUXE COAXIAL 24K,

Stepan, 37 years

I never trusted modern double-circuit gas boilers, and my instinct was completely justified. Friends persuaded me to take a model from Navien, they say it works great and is inexpensive. I had just finished building a house and urgently needed heating. I took a double-circuit unit, and after a year and a half I began to count the number of breakdowns. It’s not the most reliable device, so I can’t recommend anyone to buy it. If we are going to do heating, then we need to install a regular floor-mounted single-circuit unit with a water heater indirect heating– it will turn out inexpensive and quite reliable.

Advantages:

• Maintains hot water temperature well - perhaps this is the only truly positive trait this gas boiler from Navien;
• There is no need to buy a harness - everything is already provided inside;
• Self-diagnosis can show errors and failures.

Flaws:

• The heat exchanger was probably made of foil, since it was the first to fail. They called the master, he shook his head and said that stainless steel was nonsense, that it was necessary to take a boiler with a copper heat exchanger;
• One of the buttons on the remote control quickly malfunctioned;
• A gas boiler from Navien often shows errors that actually do not exist - the electronics are probably faulty.

Gas boiler Navien GST 35KN

Olet, 57 years old

For my country house, I purchased a powerful 35 kW floor-mounted double-circuit boiler. This choice was quite obvious - I trust full-fledged floor-standing units more than tightly packed wall-mounted modifications. I was not mistaken in my choice - the gas boiler pleased me with its trouble-free operation, the Koreans did a good job. And the hot water supply performance here is impressive, up to 22.1 l/min - not a single wall-mounted model can boast of such a characteristic. The unit is located in the basement, from which a control panel with a room thermostat rises to the first floor.

Advantages:

• It is convenient to program operating modes for a week in advance. Since I’m in the city on weekdays, the device operates in antifreeze mode, saving money in my wallet. By Friday evening, it begins to fill the house with warmth, so my family and friends arrive to an already warm home;
• Nothing prevents you from simultaneously opening the hot water taps in the shower stall and above. kitchen sink– the productivity is sufficient for all water points;
• It can run on liquefied gas, which was a big help in the first year, then a gas main appeared in the village.

Flaws:

• For the first year, the Navien gas boiler stood in a small boiler room on the ground floor, but then we had to move it to the basement - it was noticeably noisy;
• Frequent switching on and off of the burner - reacts literally to the smallest temperature changes;
• It took almost a week to start the boiler and set it up - the specialists said that the logic of this device is not the most clear.

Despite the flaws at the very beginning, further use proceeds without problems.

Gas boiler Navien SMART TOK 24K

Arkady, 61 years old

It's time to do something in the house major renovation, at the same time decided to modernize the heating system. We threw out all the old pipes and installed modern ones bimetallic batteries, at the same time we changed the gas boiler, buying a double-circuit Navien with remote control. I was very pleased with the opportunity to control the heating from a distance - I have a program with regulators on my smartphone, it works wherever there is Internet access. The thickness of the case is only 29 cm, so it does not stick out against the background of kitchen cabinets. Works faithfully and without failures.

Advantages:

• In my opinion, this is the most thoughtful gas boiler - specialists from the Korean company Navien have tried hard to give consumers an excellent heating unit with advanced remote control;
• It is possible to control the climate in the house depending on the outside temperature. Programming is also provided, but I haven’t had a chance to use it yet (maybe we’ll try it on our next vacation);
• There is no need to buy a pump and a tank - everything is already inside, without taking up space.

Flaws:

• In the very first thunderstorm, the electronics burned out - as it turned out, in gas boilers (of any manufacturer, not just from Navien) this is the most flimsy place. I had to install additional protection;
• It took a long time to understand the intricacies of control - in an effort to make the device very flexible in settings, the developers endowed it with a gigantic number of all kinds of adjustments (often not very necessary and not the most understandable);
• You can’t repair it yourself - this is not a technique that you can handle with your own hands.

The gas boiler from Navien pleased me with its automation, and you can ignore the shortcomings special attention. The main thing is to protect the electronics from electrical overloads.

If the network voltage fluctuates, the systems are triggered protective function SMPS and then the mechanism works smoothly. That is why such wall-mounted double-circuit boilers have a long service life and protect owners from breakdowns and further repairs.

Even with minimal gas pressure you can use heating and hot water. A durable protection system prevents owners from freezing. If the media temperature drops, the frost protection mechanism is automatically activated and the circulation pump starts running. The system provides reliable and uninterrupted circulation of the coolant. You can use hot water even at low pressure.

Wall-mounted double-circuit boiler Navien works great with low water pressure up to 0.1 bar, so it is widely used in residential areas with minimal water pressure in the water supply, as well as during constant power failures. The buyer receives a long service life of a wall-mounted double-circuit boiler, thanks to a heat exchanger made of reliable steel, which prevents rust and corrosion.

The Navien wall-mounted double-circuit boiler operates on the basis of the APS mechanism, which guarantees stable combustion and reduces costs for gas The mechanism controls the amount of gas that penetrates the burner, ensuring total combustion of fuel, reducing its consumption. A fan with controlled rotation speed promotes safe combustion. Therefore, the Navien wall-mounted double-circuit boiler can be used in apartment buildings. The convenient location of the APS mechanism prevents condensation.

Advantages and disadvantages of Navien gas systems

Navien gas boilers have a number of advantages, namely:

• anti-freeze protection device. When the room temperature drops, the system automatically activates an anti-freeze protection mechanism. If the water temperature drops to 10 degrees or below, The circulation pump is automatically activated, which ensures uninterrupted circulation of the coolant in the heating device. If the water temperature drops below 5 degrees, the burner automatically starts working and the coolant warms up to 22 degrees;
• control of the turbocharging system. The turbocharging fan, which is located in Navien Ice Turbo boilers under the combustion chamber, changes the speed of movement according to the counter. It is driven by an APS air pressure mechanism. Thus, air enters the combustion chamber of the system in an amount proportional to the amount of incoming gas. Only such a device works Navien systems Ice Turbo with a fan installed under the combustion chamber and the use of an APS mechanism allows for total combustion of gas and minimal heat loss;
• heat exchanger made of stainless steel. Compared to copper, it is highly resistant to rust and corrosion. And this greatly extends the service life. Although rust resistant, the stainless steel heat exchanger not widely used in boilers, since the heat conductivity is much less than that of a copper heat exchanger. And only in Navien Ice Turbo boilers can a modulated turbocharging system be used to increase the efficiency of the system;
• durable and safe operation of the system in the event of constant failures. The SMPS mechanism installed in the microprocessor protects the system from power failures. Only the Navien boiler works without significant differences. That's why The service life of the Navien system is much longer than other devices;
• amazing ability to use heating and hot water at low pressure;
• the device works great at low water pressure;
• amazing heating technology.

A portable system control distance with a built-in temperature mechanism helps not only save on gas consumption, but also significantly reduce heating costs. Therefore, your home will always have the optimal temperature.

The disadvantages of Navien gas boilers include a constant connection to the network and, despite the protection, the high sensitivity of the sensors to voltage failures. To solve this problem, different stabilizers and batteries are used.

Model ATMO

Navien ATMO gas boilers have a system for removing generated vapors through a simple chimney. This the design is adapted to work in extreme conditions with strong changes in the voltage and pressure of the gas pipeline.

NSN model

This is the most modern Navien gas boiler, which has high performance using steam temperatures. The heated condensate is collected in a heat exchanger, which heats the water flow. Thus, the costs of sources and energy carriers for heating the heat and water exchanger are reduced.

How to install a wall-mounted boiler?

So, you purchased a gas boiler, installed a gas line, installed the heating system, and now all that remains is to assemble everything into one system. Connecting any gas boiler is not an easy task. And it’s not even that it’s like this the system is a high-tech device, the problem is a little different - each device has its own connection method. Therefore, the installation of the boiler must be carried out by qualified specialists.

Before installing the boiler, if it does not have the necessary equipment, you must purchase:

• temperature emergency mechanism;
• power device;
• thermometer;
• pressure mechanism;
• fuse.

Usually all boilers are equipped with this configuration.

When installing heating systems with an open combustion chamber, you need to have a separate room. Its area should be 4 m2 or more, and the ceiling height should be 2.5 m. There should also be a ventilation system. When installing heating systems with a closed combustion chamber, such requirements do not apply. If you are installing the system, need to have an outlet with automatic emergency shutdown sensor. It is important to connect the stabilizer. The boiler is grounded. If the wall on which the boiler is installed is not resistant to fire, then it needs to be sheathed with protective material. After getting holes between the pipe and the wall, you need to seal them cement mortar. Before connecting the thermoblock, check that there is no debris in the cracks.

Connect the heating system - difficult process which must be carried out by specialists. If you want to buy a Navien gas boiler, then everyone will be happy with its low cost, and they will also be pleasantly surprised by the free installation.

Korean wall-mounted double-circuit gas Navien boilers today are the most the best option when purchasing, given the sharp rise in price of all imported heating equipment. Of course, the increase in the price of gas boilers affected all manufacturers, but you must admit, it’s one thing to pay 30-35 thousand rubles for a boiler, and another thing to buy it for 50-60 thousand.

Is it worth overpaying for essentially the same thing, only made in Italy or? Good build quality, reliability, customer reviews and, most importantly, low price have made the Navien brand very popular in Russia in recent years.

In this review, we will try to understand the Navien boiler models presented on the Russian market, their differences, design and technical characteristics, as well as the advantages and disadvantages of boilers of this brand.

Features of Navien gas boiler models

On the Russian market, the company sells double-circuit wall-mounted gas boilers, both with forced draft(turbocharged) and natural (atmospheric). They are designed for heating a house with a total area of ​​30 to 400 m2, depending on their power.

All models are dual-circuit, which makes it possible to use them for heating household appliances. running water for household needs. They can operate on natural and liquefied gas.

Gas boilers Navien Prime and Navien Deluxe

The productivity of hot water also depends on the power of the gas boiler. The higher its power, the more water it will give you. Boilers with a power of 13 kW produce 10-11 liters of hot water per minute, from 16 kW to 24 kW - 14 l/min, from 30 kW - about 16-17 liters. In practice it has been proven that for good provision For a family of several people, a productivity of 14 l/min is sufficient for hot water.

Turbocharged boilers are presented wide range power from 13 to 40 kW. The number in the abbreviation indicates thermal power specific model of wall-mounted boiler.

In stores you can find the following models:

— Navien Deluxe 13k;
— Navien Deluxe 16k;
— Navien Deluxe 20k;
—Navien;
— Navien Deluxe 30k;
— Navien Deluxe 35k;
— Navien Deluxe 40k.

Navien Deluxe Coaxial boilers - Technical characteristics

Table of technical characteristics of Navien Deluxe Coaxial boilers

In addition, turbocharged (with a closed combustion chamber) double-circuit gas boilers from a Korean manufacturer differ in the type of exhaust of combustion products and air supply.

They come in two types:

— with a coaxial chimney;

- with a separate chimney.

Navien boilers with coaxial chimney are marked Deluxe Coaxial. In previous years, a 24 kW turbocharged boiler was designated as Navien Ace 24 E. Where the letter “E” meant “Euro”, i.e. European type of chimney pipe.

Coaxial chimney- This is a chimney of the “pipe-in-pipe” type. Through the outer pipe there is an influx of air into the boiler from the street, and through the inner pipe there is an emission of combustion products. The diameter of these pipes is 60/100 mm, as indicated in the instructions.

For those situations where, according to the project, installation of a gas boiler is impossible, practical and cunning Koreans have come up with a boiler with the ability to install the so-called separate chimney.

This type of turbo boiler is already equipped with two connection pipes: the first pipe, which emits combustion products, and the second, for air intake. Instead of the second pipe, you can also use aluminum corrugation, it is cheaper. The diameter of the pipes is 75 mm and 70 mm, respectively.

This type of boiler is marked with the letter “K”, i.e. Korean version of the chimney. For example, if you see the designation Navien Deluxe 16K on the price tag of a boiler in a store, this means that this is exactly the type of double-circuit gas boiler made in Korea. See the photo below.

When choosing a boiler, also keep in mind that boilers with a Korean version of the chimney are produced with a maximum power of up to 40 kW inclusive, while with coaxial pipe- only up to 30 kW.

Navien Deluxe 24K boiler with channel separator

Navien range of gas boilers with open combustion chamber presented in models with a power of 13, 16, 20 and 24 kW for heating rooms from 30 to 240 m2. They are marked Navien Ace 13-24 A.
The symbol “A” tells us that this device is naturally aspirated, and the numbers indicate its power. Boilers of this type do not have a fan (turbine), and combustion products are removed by natural draft.

You can buy an atmospheric boiler if your house already has a chimney, for example, made of asbestos-cement pipes, sandwich pipes or brick pipes. You will just need to purchase separate steel pipes (preferably stainless steel) and run them into an existing chimney.

The diameter of the pipe on the boiler is 130 mm. This is important to remember, because you cannot narrow the chimney.
And, if, for example, you have an asbestos pipe installed with internal diameter 100 mm, then it will have to be replaced with pipes of larger diameter. Otherwise, the boiler will not work correctly and will quickly fail.

Installation of double-circuit gas boilers of the Navien brand

Like most modern double-circuit wall-mounted gas boilers, South Korean-made boilers are equipped with:

Construction of a double-circuit gas boiler Navien Deluxe Coaxial

— the main heat exchanger for heating water in the heating system;
— secondary heat exchanger for heating hot water;
- circulation pump;
- membrane expansion tank;
— electronic board (“brains” of the boiler);
— burner assembly;
— safety group (air and safety valve, pressure gauge, sensors);
— three-way valve to switch the operation of circuits;
— turbine (for versions with forced draft).

Design features of Navien double-circuit boilers

1. Navien boilers have two separate heat exchangers: one for heating, the second for flow domestic water. Important feature is that both heat exchangers are made of stainless steel.

Then, like most competitors, only the secondary heat exchanger is made of stainless steel, and the main one is made of copper, or there is only one bithermal copper heat exchanger for heating both circuits. Stainless steel itself guarantees long term gas boiler service.

2. Another important point is that the company produces all the boiler elements itself. Both the pump and the membrane tank and heat exchangers are produced in South Korea. Unlike, say, many others, which often have parts from different manufacturers installed.

3. The electronic board of the Navien boiler has a special built-in chip to protect against power surges. The same protection for the “brains” of the boiler is provided only on wall-mounted gas boilers made in Germany, but heating equipment This brand belongs to a different price category.

But, despite this chip, experts still recommend buying, taking into account our Russian realities, when the range of power surges can be quite significant.

4. And finally, the most noticeable distinctive feature Korean manufacturers are remote boiler control unit Navien. This is a special “box” that has a digital display and buttons for controlling the operation of the boiler.

Navien boiler control unit

The display displays information about any malfunction or error during the operation of this equipment, the set temperature of water, coolant, air, as well as time. Using the buttons, the operating parameters are manually set: mode, temperature, turning the boiler on and off.

Very important point- this is the presence in the control unit of a built-in room temperature sensor. Typically, other manufacturers consider this sensor as additional option, and is purchased for an additional fee.

For the “Koreans”, it comes complete with a boiler. And you don’t even need to buy wires: both the boiler and the unit already have them. The difference is the boilers of the series Navien Prime And Navien Deluxe Plus. The control unit here is built into the body of the device and, as a result, there is no ambient temperature sensor.

Connecting and installing the Navien boiler

Like all wall-mounted double-circuit gas boilers, the “Koreans” have 5 fittings at the bottom of the body for connecting water and gas. The order of the fittings is from right to left: gas connection, running water inlet and outlet, coolant inlet and outlet.

The diameter of the fittings for service water is 1/2 inch, gas and coolant is 3/4 inch.
Be sure to install on each supply pipe.

Between the boiler and the wall on which it will hang, it is necessary to install a protective stainless steel screen measuring 1000 by 600 mm for fire safety purposes. Also for correct installation The boiler on the wall includes a special mounting strip.

Connecting the Navien Deluxe Coaxial gas boiler

Advantages of Navien boilers:

— good price-quality ratio;
— two heat exchangers made of stainless steel;
— presence of a remote control unit with a built-in air temperature sensor;
— presence of a protective chip against power surges;
- wide the lineup and color scheme;
- cheap spare parts.

Disadvantages of Navien gas boilers:

— noise during operation;
— only original spare parts are suitable;
- Asian brand.

So, we looked at the range of Korean wall-mounted double-circuit gas Navien boilers, their differences, dismantled the external and internal organization boiler Let's watch a video review of the boiler.

Looking at specifications, as well as reviews from owners and specialists, Korean-made Navien boilers are perhaps the best today when choosing heating equipment, if we take into account such parameters as price and quality. Overall, this is a very decent and inexpensive device for modern system heating your private home.

The Navien gas boiler is a profitable purchase in light of the sharp rise in price of imported heating equipment. Korean heaters are 30-40% cheaper than their European counterparts. At the same time, they are in no way inferior to the “Europeans” in build quality and reliability.

About company

Korea has long been famous for high-quality electronics and household appliances, heating equipment was no exception. NAVIEN is a giant enterprise specializing in the production of boilers operating on gas and diesel fuel. The components are made in Korea and Japan. Assembly - only in Korean factories. Previously, the company supplied its products to the US and Pacific markets. Since 2007, promotion to European markets began. Today, Navien actively supplies its goods to Russia.

The most common problems

Often the causes of problems are low quality coolant or gas. Error codes help you solve problems. Here are the most common malfunctions that can happen to Korean gas equipment:

• Overheating.
• No flame signal.
• The fan is faulty.
• Control board failure.
• Short circuit in the flow sensor circuit.

Error codes

Despite the saturation of electronics, Korean heaters are functional, like any equipment, they can break down. Startup and operation do not always go smoothly - problems may occur during the process, and numbers appear on the display - error codes. The decoding of the codes can be read in the instruction manual. Common problems:

• Error "01". May occur due to a clogged system or pump malfunction.

• Error "02". The heating system flow sensor has tripped. There are several reasons:

— air has entered the system;

— the coolant filter at the inlet is clogged;

- there is a leak;

- sensor is broken.

If error “02” disappears hot water. The water temperature rises sharply and then drops. It is likely in DHW system- air lock. She appears from low pressure, poor operation of the circulation pump, breakdown of the flow controller. In this case, you need to adjust the pressure and bleed air from the system.

• "03". The flame sensor worked - it “did not see” the fire. Causes:

— low gas pressure;

— the ignition electrodes are dirty;

— poor gas quality;

— the sensor is broken or there is a break in the electrical circuit conducting its signal.

• "10". Incorrect combustion products are removed. Causes:

— the turbine is broken;

— the pressure sensor is incorrectly connected;

— the chimney is clogged;

— excessive length of the pipe.

It happens that there are no problems with the chimney - perhaps the signal is caused by gusts of wind. Then the reason is in the chimney - it needs to be redone. To temporarily correct the situation, you can remove the air supply hose. But this is done only as a temporary measure.

All Navien modifications are reliable, but the duration of their operation largely depends on how the installation was carried out, how the maintenance is carried out and whether the settings are set correctly.

Differences between Navien and analogues

The Korean manufacturer is among the few that use their own designs. The brand does not produce modified or slightly improved versions - each new modification is worked out to the finest detail. Among the design advantages it is worth noting:

• Remote control via iOS and Android systems. This is for the SMART TOK series.
• Modulating burners. Quiet operation depends on them; they are responsible for maintaining a comfortable temperature for humans.
• Thanks to voice prompts, the operation and configuration of the devices is simplified. If the user is not well informed about how the device works, voice prompts and error codes will help him.
• Meets our conditions - possible decrease in pressure, voltage surges in electrical networks, pressure drops in gas pipes.
• Self-diagnosis. The device itself determines its “diseases” and notifies the user about them by displaying an error code on the display.

Korean manufacturer, taking into account possible risks, created safe and easy-to-use equipment. If you take an interest in the statistics of reviews, it becomes clear that consumers have managed to evaluate the quality of heat exchangers and burners, as well as uninterrupted operation Korean heaters. Only 2% of buyers contact service centers, and even then, the problems are usually caused by incorrect connection or operating errors. To prevent the boiler from creating problems, you need to connect it correctly and configure it correctly. It is also important to know how to use gas equipment - for this purpose, instructions are attached to each piece of equipment. The kit also includes a passport and connection diagram.

Advantages

The brand positions its heating equipment as optimal according to the price-quality formula. Navien boilers can be used for heating a private house, apartment, production premises. Their advantages:

• Resistant to voltage surges. Its surges often lead to equipment failure. The Koreans have foreseen reliable protection– we installed the Switched-Mode Power Supply control chip – it expands the voltage range to 165-300 V.
• Resistant to low blood pressure gas Many modifications refuse to work because of this, but not Navien - they continue to work at the lowest values.
• Pleasant, ergonomic design.
• Any Navien boiler is double-circuit. This means that, in addition to heating, its owner receives an addition in the form of hot water supply.
• A wide range of powers is offered - you can choose an option for any room.
• Equipment owners can always get professional help V service center. Contact details can be found in the attached documentation.

Are there any disadvantages?

• The cost is higher compared to Russian analogues.
• In the event of a breakdown, you have to look for imported components.
• Need regular maintenance.

But these shortcomings can be disputed. By paying more, you get a reliable device, forgetting about unstable operation and other shortcomings inherent in many domestic boilers. The issue with spare parts is also resolved simply - they can be ordered at authorized Navien centers. And finally regular maintenance- so without it, not a single technique will last long.

How to turn it on?

You can turn on the device in two ways:

• Remote control.
• Using the buttons on the control panel - you just need to press "Power".

After startup, the device begins to operate in the specified mode - which was previously set. To change the settings, you need to use the manual and set the modes correctly. Before starting the device, it is installed, connected to engineering networks, fill the heating system with coolant - keeping an eye on the pressure gauge.

Model overview

Many users initially gave negative reviews about Korean boilers. Reasons: leaks in connections. They had to be eliminated by replacing the gaskets - you need to buy a rather expensive kit. The second flaw was associated with the belated start of the burner - the coolant had time to cool down more than necessary. But the company corrected the shortcomings; today there are practically no such accusations against Navien. The brand produces three types of mounted heaters:

• atmospheric;
• condensation;
• turbocharged.

The consumer can purchase a gas boiler:

• Single-circuit or double-circuit.
• Wall or floor. The latter are more bulky and require a separate room.
• With open or closed combustion chamber.

The widest range is in the line of mounted models. It is these devices that are in the highest demand among Russian consumers.

Navien Atmo 24AN and others

The atmospheric wall-mounted device Navien Atmo replaced the less successful modification of Ace. It can operate at extremely low fuel pressure - 8 mBar, and water - 0.6 Bar. There are 4 models of different power in the series - 13, 16, 20, 24 kW. The heat exchanger for heating is made of copper. For DHW – made of stainless steel. Automatic control. There is a remote control. There is frost protection. Specifications:

• 24 kW.
• Heating of water in the heating system is 80 °C.
• Circuit pressure (maximum) – 3 Bar.
• Efficiency – 86%.
• The maximum water temperature in the hot water supply is 60 °C.
• Weight – 27 kg.
• Estimated cost 26-27,000 rubles.
• Heating area – 240 m².

Important! The system can only be filled with water - antifreeze is prohibited.

Deluxe 24K and other turbocharged versions

The line of turbocharged modifications is represented by three series Deluxe (13-40 kW), Prime and Smart TOK(13-35 kW). “Navien Ice Turbo” is an outdated model; it was replaced by Deluxe and Prime devices. Pressurized heaters have a closed firebox, and air is forced into it by a fan. The fan performance is regulated by the controller. To allow air to enter the chamber, a coaxial chimney is installed. Due to forced injection, turbocharged modifications are characterized by increased efficiency.

There are no further differences between the turbocharged and naturally aspirated versions. The equipment is completely similar - expansion tank, pump, additional heat exchanger.

The Prime series, like the Deluxe Coaxial, has a closed firebox and all the usual elements of a turbocharged model. But in Prime there is additional module– weather-compensated automation. Characteristics of the 2-circuit wall-mounted boiler Deluxe 24K:

• Efficiency – 90.5%.
• 24kW.

auto ignition

• Maximum heating area 20 m².
• Natural gas consumption - 2.58 m3/h.
• Dimensions (WxHxD) – 440x695x265 mm.
• Weight – 28 kg.

NCN 40KN and other condensing models

The operating principle of a condensing heater is based on the use of both direct and latent heat released during gas combustion. This allows you to achieve high efficiency values ​​- more than 100%. Condensing heaters are represented by Navien NCN and NCB models. Their heat exchangers are made of stainless steel. The equipment is similar to the turbocharged versions. The difference is that the controller’s functions are expanded. For example, he can program work for the next seven days. NCN is represented by 4 boilers 21-40 kW, NCB is also represented by 4 models 24-40 kW. Air is supplied forcedly through a coaxial or separate chimney. For example, the characteristics of NCN 40KN:

• 40.5 kW.
• Two circuits. Wall installation.
• Closed firebox.
• Auto-ignition.
• Weighs 38 kg.
• Efficiency 107.4%.
• The maximum heating of water in the DHW is 65 °C.

LST 30 KG and other floor models

The brand presents a line of floor-standing boilers of four series - LST, LFA, GA, GST with a capacity of 13-60, 13-40, 11-35 and 35-60 kW, respectively. Each of the presented samples is a universal floor-standing device that can work as natural gas, and on diesel fuel. Floor-standing versions, no less than wall-mounted ones, are full of automation. For example, the characteristics of LST 30 KG:

• 90% efficiency.
• Weight – 45 kg.
• 30 kW.
• Heated area – 300 m².
• Auto-ignition.
• Volatile.

How does Navien Ace TURBO work?

For example, consider the description of the operation of a turbocharged heater. Such a device is not afraid of low fuel pressure or power surges. It will heat any area. At the same time, it heats the water - there is a second circuit. DHW heat exchanger – steel. It is much cheaper than copper analogues. The lack of power - due to the insufficient thermal conductivity of steel - can be compensated for by turbocharging the burner. Such devices easily compete with analogues that have copper heat exchangers.

The turbo heater monitors the temperature of the coolant - if it drops below plus 10 degrees, the circulation pump turns on. It drives water, preventing ice crystals from forming. When the temperature drops below plus 6 degrees, the burner will light up and heat the coolant to +21 degrees.

Turbocharged devices are available in two modifications, the second - with a coaxial chimney “Navien Ice Turbo Coaxial”. It is advantageous to install it in rooms where it is impossible to ensure a normal supply of oxygen. A coaxial chimney takes air from the street.
