Gas wall-mounted boilers navien. Korean gas boilers Navien. Technical characteristics of boilers Navien Smart Tok Coaxial, Navien Prime Coaxial

Gas boiler "Navien" - 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, was no exception and heating equipment. 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.

With error “02”, hot water disappears. The water temperature rises sharply and then drops. It is likely that there is an air lock in the hot water system. It appears due to low pressure, poor operation of the circulation pump, or 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.

The 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 the uninterrupted operation of 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 gas pressure. 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 in 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 work 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 - without it, no equipment 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 feedback 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 with closed camera combustion.

The widest range in the line 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.

Deluxe 24K and other turbocharged versions

The line of turbocharged modifications is represented by three Deluxe series(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.

Prime series, like 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 2-circuit wall-mounted boiler Deluxe 24K:

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:

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, it turns on circulation pump. 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. Coaxial chimney takes air from the street.

Korean wall gas Navien boilers popular in Russian Federation for several reasons:

Gas fuel is the cheapest fuel that a Russian consumer can afford, therefore, heating bills will not be astronomical.
The most important factor in the ongoing popularity of Navien wall-mounted gas boilers is their affordable price. Having similar quality to German brands, Korean models are 30% cheaper!

By visiting the store, you can get acquainted with a large assortment of similar products, but the most popular today is the Navien boiler. Malfunctions can occur during its operation, as with any other equipment. However, you can try to solve the problems yourself by using the error code that is indicated on the interactive panel.

Most common problems

The Navien boiler, the malfunctions of which almost every user can fix, sometimes breaks down during operation, like any other equipment. This is due to the fact that low quality coolant may be used. In order for the consumer to be able to determine the cause and make a decision, Navien brand boilers display an error code. Below are examples of problems that occur most frequently:

overheat;
lack of flame signal;
open circuit in the temperature sensor;
circuit damage;
problems with the fan;
short circuit of the flow sensor;
disruption of the system;
control board malfunction.

You may experience problems with equipment overheating, as well as false fire messages.

Troubleshooting

If you purchased a Navien boiler and malfunctions may occur during its operation, then you, like every user, need to know the main error codes and troubleshooting options. Some owners immediately contact a service workshop and do the right thing, since only in this case will the equipment be covered by the warranty when repairing the device.

If you see error 01 on the display, you should know that this malfunction is the most common. It is expressed in a decrease in heating flow or blockage. The same error code occurs when the circulation pump fails.

Decide this problem you can by following these steps. It is important to check the filter in the heating system for air pockets; if necessary, they should be vented. The technician needs to make sure that the pump is working properly and the coil resistance is closed. It is necessary to take care of the functionality of the impeller; it should not be damaged, and you can find it in the circulation pump.

Error number 02

The Navien boiler, the faults of which are displayed on the display, may encounter an error, which is indicated by the numbers 02. If the double-circuit equipment produces such a code, then warm water may flow from the hot tap for a few seconds, then cold water flows, and on the remote control the water temperature rises to maximum, then this parameter drops sharply. In this case, everything may be fine with heating, but the reasons for the error that occur are sometimes a lack of water or an airy system.

In some cases, you may notice that it works, but does not have the ability to gain the necessary momentum. Sometimes with error 02, users note that the impeller has mechanical damage. Sometimes the flow sensor in the coolant system does not work, and the heating distribution valve is closed.

Options for eliminating error 02

The Navien gas boiler, malfunctions of which can be an unpleasant surprise for the user, sometimes displays error 02. In this case, the technician should adjust the pressure, ridding the system of excess air, and also analyzing the resistance of the pump coil. The impeller should be checked for damage, as in the case described above. The resistance of the flow sensor needs to be checked for short circuit, open the distribution valve, and then disassemble the sensor housing, which will allow you to clean the flag. The Navien gas boiler, malfunctions of which led to error message 02 on the display, most likely encountered an air lock problem. In this case, the water is in the circuit, heating up, but after air enters, the temperature drops sharply, it reaches a critical point, which is why error 02 appears on the display.

Error 10 occurs

Error 10 is issued when the fan malfunctions; it may be bent, and in some cases the air pressure sensor tubes are incorrectly connected. They should lead to the fan volutes. Sometimes error 10 is indicated by a clogged chimney or strong gusts of wind.

Ways to solve the problem

The Navien wall-mounted gas boiler, malfunctions of which can be indicated by the number 10, must be repaired, which sometimes involves replacing the fan. If necessary, a technician should clean the chimney. You should make sure that the connection of the tubes leading to it is carried out correctly. They must have a bend.

The occurrence of noise

Sometimes users notice that a double-circuit boiler begins to make noise when turned on, but no error appears on the display. The pressure in the heating circuit can be 1.5 atm, and the solution to the problem is to use a high-quality coolant that will not lead to damage to the heat exchanger. If you still encounter this problem, the heat exchanger must be removed and cleaned, replacing it with a new one if necessary.

Error 011

Malfunctions of the Navien Ice boiler are sometimes accompanied by an error message in the form 011. It indicates that the coolant is full. If you purchased equipment designed for the European market, then such an error may occur, but with adapted boilers it is not possible.

Conclusion

“Navien” - boilers whose fault codes were listed above are characterized by reliability, ease of operation and installation, as well as versatility and safety. These quality characteristics more often force consumers to choose such devices to provide housing with hot water and install a heating system.
