Finding a suitable gas boiler today is very difficult - as always, the main problem lies in the huge choice. Even the products of one manufacturer can impress with an extensive range of models, not to mention several dozen brands on the heating market.

The Korean-made Navien gas boiler simplifies this task - each line contains Navien's own developments of engineers, optimized in terms of power, energy consumption and ease of operation. Why, among all the variety, buyers prefer this particular heating technique - in our article.

What distinguishes Navien equipment from analogues

The Korean company is one of the few in the world that prefers to use its own developments in the production of heating equipment. OEM products are not produced here - modified early samples to increase sales. Each piece of equipment is worked out to the nuances, which allows you to create equipment that is ideal for autonomous heating of private houses, apartments and industrial enterprises.

Wall mounted gas boilers Navien

Among the key advantages over the products of other brands are:

• intelligent remote control via iOS or Android systems - the SMART-TOK line of boilers;
• modulated gas burners responsible for the silent operation of the unit, a gradual change in temperature in a mode that is comfortable for a person and the absence of thermal effects on the internal structure;
• modulated by a turbocharging system with a large operating range of regulation;
• voice prompts for easy control and configuration of Navien gas boilers;
• full compliance with Russian operating conditions - low gas pressure, voltage drops in the network, lack of constant pressure in pipes, etc.

In other words, the Korean manufacturer took into account all the potential risks and offered a completely new vision for gas equipment. It has become not only convenient, but also completely safe.

Studying real reviews on Navien gas boilers, it becomes clear that buyers have already managed to evaluate the stability of burners, the quality and insulation of heat exchangers, and a very long period of trouble-free operation. Even according to experts of service centers, breakdowns of Navien equipment are treated in only 2% of cases, and in most cases this is due to an installation error or incorrect reading of the instructions.

VIDEO: A simple solution to the main problem of wall-mounted gas boilers

Studying the reviews of owners and specialists, it is clear that in general this is a fairly reliable equipment that rarely fails. But problems arise here too, and often this is due precisely to errors or peculiarities of operation.

In some cases, you need to immediately contact the service center, especially since the gas double-circuit wall-mounted boiler Navien is repaired under warranty only if there was no third-party intervention.

Error code 01

This error means pressure drop. The reasons may be the failure of the circulation pump or the formation of a plug (clogging).

What to check:

• a filter so that there are no air pockets - you can bleed on radiators;
• operation of the circulation pump;
• coil resistance;
• operation and no damage to the pump impeller.

After the end of the warranty period, all problems must be checked and repaired by a qualified technician. The gas boiler does not allow amateurism, so it's not worth the risk.

Error code 02

It means the appearance of air locks in the system, a decrease in water pressure, damage to the pump impeller. In addition to the error code that is displayed on the display or plateau, the indicators are:

• lack of hot water from the tap - at first it can go warm, then generally cold, since the flow force is not enough for the burner to work;
• cold water at the maximum temperature on the remote control;
• no hot water, but the heating works properly.

What do we have to do:

1. Bleed air pockets.
2. Check coil resistance.
3. Check the impeller for mechanical damage.
4. Check the operation of the flow sensor.
5. Disassemble the flow sensor if it is defective and clean the flag. It is he who is responsible for coordinating the flow pressure.

Error code 10

The reasons may be:

• fan malfunction;
• installation errors in which the air pressure sensor is incorrectly connected;
• chimney blockage;
• a sharp strong wind blowing out the burner.

What to do:

1. If the fan is damaged, replace it.
2. Clean the chimney with chemicals.
3. Check that the sensors are connected correctly.

The appearance of noise in the boiler

It is very rare, but it occurs when the Navien wall-mounted gas boiler starts to make a distinct noise when hot water is supplied, but does not give an error. The reasons may be a poor-quality coolant or an increase in water pressure. As a rule, we are talking about clogging of the heat exchanger, so it must be removed and thoroughly cleaned.

When operating equipment for more than 5 years, it is almost impossible to clean the heat exchanger, so it is better to buy a new one and install it.

Error code 011

This problem is typical for gas boilers with a storage tank and shows that the heat exchanger is clogged with low-quality coolant. In most cases, such an error appears on original equipment that is not adapted to our conditions. You can order an adapted gas boiler from authorized dealers, which no longer reacts to water quality.

Not a single error can be called critical for the operation of the equipment, especially since the owner of any boiler, not only the Korean Navien, may encounter this. Another thing is that the latter rarely fails, which is what Russian users appreciate.

The entire Navien Deluxe series is adapted to work in conditions of frequent power supply voltage fluctuations (a chip with a response threshold of ±30% of 230 V is installed). Both circuits are active even at low pressure in the incoming water pipe (up to 0.1 bar). The presence of a turbocharged fan allows you to optimize the "fuel-air" ratio and reduce heat losses from the outgoing combustion products.

3. Navien Ace 24.

Sales leader Navien, according to reviews, this boiler from Korea is trouble-free even with unstable parameters of gas and water in the supply lines, often observed in our realities (for example, apartment buildings). An anti-freeze system is provided: when the gas boiler is turned off, the pump circulates the coolant, and when the temperature drops to -6 ° C, the burner automatically starts. The installed air pressure sensor allows you to optimize fuel consumption: it takes no more than 2.47 m3/hour to heat a room up to 240 m2 and meet the needs of hot water supply. The Coaxial chimney is not included in the standard kit (there are exceptions, but according to reviews it is worth clarifying), to organize the forced removal of combustion products, it must be purchased separately.

4. Navien GA 17KN.

Floor double-circuit gas copper. Optimum in conditions of low gas pressure and water pressure, the performance when heated to 25 ° C reaches 9.8 l / min. The efficiency of this is 91%, due to the rational arrangement of steel heat exchangers, the fuel consumption is minimal - no more than 1.67 m3 / h with a thermal power of up to 1.7 kW. By analogy with the above-mentioned Navien gas heating boilers, this model provides reliable protection against freezing (it reacts to a sharp change in the temperature of the heated space) and voltage drops. A feature of Navien GA 17KN is a universal smoke exhaust system - the hole can be installed in the outer wall, it is not necessary to lead the pipe vertically. The remote control panel is Russified, it is possible to control the parameters of water heating.

5. Navien NCN 21KN.

A wall-mounted condensing gas boiler, due to the use of the heat of the outgoing combustion products, the efficiency of the device reaches 98-108%. This is an environmentally friendly heating technology, flue gases contain a minimum of hazardous substances compared to conventional two-circuit models with the same performance. The generated volume and speed of hot water supply is above average: 14 l / min when water is heated to 25 ° C, 8 - to 40. At the same time, Navien condensing boilers are not inferior in terms of safety to other varieties: there is a system of protection against freezing, power surges. Successful operation is allowed at low pressure of the energy and heat carrier in the supply lines.

Another feature of this Navien model is the ability to control power over a wide range: from 4.8 to 19.3 for the heating circuit, which leads to savings in gas consumption. For comparison: in the minimum mode, the gas boiler consumes 0.52 m3 / h, in the maximum mode - up to 2.09, while a rather significant heating area is covered - up to 190 m2. Savings are 30% or more, this is achieved both by modulating the heat output of the burner (from 20 to 100%), and thanks to climate control, which monitors temperature changes not only in the room, but also outside it. User reviews confirm the payback of this unit, maximum efficiency is observed when it is installed in low-temperature heating systems.

6.Navien Prime 13K.

Wall-mounted gas boiler with a remote return line sensor that monitors changes in weather conditions. The presence of a climate control system allows you to reduce fuel consumption and save heat exchanger resources.

The kit includes a remote control with a voice assistant, control is available to people with visual problems. The series is protected from voltage surges and is suitable for operation in domestic conditions.

Buyer opinions

“I chose the gas Navien Deluxe 24K as the main heating device for the cottage due to the impossibility of allocating a separate room for the boiler room, the wall model just fit. During the operation did not reveal any particular shortcomings or malfunctions. The disadvantages include dependence on the mains and specific noise - the greater the power, the stronger the rumble of the boiler.

Egor, Yekaterinburg.

“I decided to buy Navien Ace to replace a failed gas boiler, after wintering I noticed a slight decrease in gas consumption, convenient and accurate automation. During the year of operation, he stopped for no particular reason twice, after which he restarted manually, and did not understand what it was connected with. The chimney is noisy, but you can’t hear it behind the closed door, I didn’t find any obvious minuses or shortcomings. ”

Sergey Trofimov, Moscow region.

“I consider Navien boilers a good investment, this equipment from Korea is better suited for our conditions than European models, and it consumes gas more economically than Russian ones. Of course, they are dependent on electricity, but the same can be said about any heating circuit with a circulating pump, and the fans consume little. Noise is called a generally recognized disadvantage, but they are located in a convenient place for the owner, the main thing is that the lighting is normal.

Dmitry, Novosibirsk.

“I installed the Prime 13K boiler from Navien at home, there are enough resources for efficient heating of all rooms and hot water for a family of three. I liked that the thermostat was included in the basic kit, I did not have to buy it separately. Malfunction signals are displayed, the control system is Russified, there are no problems with starting and maintenance.”

Denis, Moscow.

“I have been using a condensing double-circuit gas boiler of the Navien brand for heating and hot water needs for more than a year, during the operation I did not reveal any malfunctions. The cost of the model is one and a half to two times higher than the usual wall counterparts from Korea, but it is worth buying if you need a significant consumption of hot water. I advise you to connect the boiler through a stabilizer, in my area, for example, power surges exceed the 30% specified in the instructions.

Andrey, Rostov-on-Don.

Price

* the weight of the boilers is indicated without water.

The company "Kyung Dong NAVIEN" presents under the brand name "NAVIEN" a double-circuit wall-mounted gas boiler with a closed combustion chamber, adapted to Ukrainian operating conditions and having a good price-quality ratio. Boilers NAVIEN work without problems in our conditions. They are not afraid of the low pressure of gas and water, they can easily cope with voltage drops in the network. The operation of NAVIEN boilers is characterized by a long service life and economical gas consumption. NAVIEN boilers comply with all norms and standards adopted on the territory of Ukraine, and have the appropriate certificates.

Freeze protection system.

When the room temperature drops, the boiler automatically activates the frost protection system. If the temperature of the heating water drops below 10°C, the circulation pump automatically starts, ensuring constant circulation of the coolant in the heating system. When the heating water temperature drops below 6°C, the burner automatically turns on and heats the coolant to 21°C.

Modulated turbocharging system.

The turbocharging fan installed in the NAVIEN Ace TURBO boilers under the combustion chamber changes the rotation speed according to the signal from the APS (Air Pressure System) air pressure sensor. Thus, air is supplied to the combustion chamber of the boiler in an amount proportional to the amount of gas supplied. It is this system of operation of the NAVIEN Ace TURBO boiler, with the installation of a fan under the combustion chamber and the use of an APS sensor, that made it possible to ensure the most complete combustion of gas and minimize heat losses associated with smoke removal. The performance of NAVIEN Ace TURBO boilers has increased without increasing the amount of gas consumed, and the efficiency of NAVIEN Ace TURBO boilers with a stainless steel heat exchanger has become the same as for boilers with a copper heat exchanger.

A heat exchanger made of stainless steel, compared with copper, has a 5-6 times higher resistance to corrosion, which significantly increases its service life. Despite the increased resistance to corrosion, a stainless steel heat exchanger has not been widely used in boilers, since its thermal conductivity is lower than that of a copper heat exchanger. The efficient use of a stainless steel heat exchanger has become possible in NAVIEN Ace TURBO boilers, thanks to the use of a modulated turbocharging system to increase the efficiency of the boiler.

Safe and flawless operation of the boiler with frequent voltage fluctuations in the mains.

The SMPS chip (Switched-Mode Power Supply) on the microprocessor protects the boiler from power surges within ± 30% of 230V. At the same time, the boiler works without failures and stops, due to which its service life is extended and breakdowns associated with unstable voltage are prevented.

Possibility to use heating and hot water with low inlet gas pressure in the gas pipeline system.

The boiler works stably when the incoming water pressure drops to 0.1 bar, so it can be used in residential areas with low water pressure in the water supply system, as well as with frequent pressure drops in the water supply system.

Exceptional heating technology - constant adaptation to room conditions

The remote control panel for the boiler with a built-in temperature sensor allows not only to save gas and reduce heating costs, but also constantly automatically maintains the desired comfortable temperature in the heated room.

Modifications Korea and Coaxial.

NAVIEN Ace TURBO boilers are supplied to the Ukrainian market in Korea and Coaxial modifications.
Boilers NAVIEN Ace TURBO Korea and NAVIEN Ace TURBO Coaxial have the same design and specifications, but differ in the smoke exhaust system. For more information, please refer to the NAVIEN Ace TURBO Korea and NAVIEN Ace TURBO Coaxial manuals, which can be downloaded from this page.
