The latest double-circuit gas boiler
The products of the South Korean company Navien are widely represented on the Russian market of heating equipment. It is characterized by versatility, reliability, high level of automation and workmanship. Practicality and functionality gas boiler Navien is known far beyond South Korea. The technique is excellent for providing heat for industrial buildings, offices and residential premises.
Consumer characteristics
Modern high-tech equipment will immediately save the user from many problems. It is especially important that boilers can work even with low-quality electrical energy. They do not respond to voltage fluctuations, even if it changes by 30%. This is very important for all consumers in the post-Soviet space. Indeed, in domestic networks, it is not so rare that various interferences occur.
Navien products work flawlessly for more than just this reason. The high quality of all components and the professional assembly of the systems determine the reliability of the equipment. It can only fail if the pressure in the system drops. But this is more a plus than a minus - if the liquid leaks, the boiler will stop working, which will save you from more serious problems.
The minimum possible pressure of the secondary circuit (0.1 bar) allows you to get hot water for household needs almost uninterrupted.
Two heat exchangers
The main feature inherent in all Navien gas boilers without exception is the presence of two heat exchangers. This allows more efficient use of the heat produced during the combustion of the energy carrier. The devices are resistant to corrosion. Their metal components are made of stainless steel, which guarantees a long service life.
It is very important for consumers and what is relatively inexpensive. So it is available to almost all categories of the population of the country.
Both heat exchange circuits in heating devices are resistant to various kinds of pollution. They do not collect fine particles and resist the formation of scale well. This ensures consistently high performance. The nodes are affordable and easy to maintain.
Turbo fan installed in NAVIEN Ace TURBO boilers
Each product of Korean manufacturers is equipped with a device that provides air under pressure. Due to this, the gas combustion coefficient is very high, which favorably affects the efficiency index. Air supply control is performed automatic systems equipped with APS pressure sensors.
It is very important to note that turbocharging significantly increases the performance of the equipment. In terms of heat transfer, such installations are comparable to gas boilers equipped with copper heat exchangers. At the same time, the strength of convection units remains consistently high, and the cost is much lower.
Mixture balancing
The engineering staff of the company pays a lot of attention to the design of their models. No less carefully controlled and production processes. The tandem of these two components explains why gas boilers Navien are of such high quality.
Careful study of even the smallest nuances made it possible to achieve the supply of a perfectly balanced working mixture to the combustion chamber. As a result, the amount of heat produced has increased significantly.
Boilers of the South Korean brand are characterized by undeniable advantages:
- High power of the fans installed in the equipment.
- Optimal ratio of atmospheric air and natural gas.
- Reducing the emission of harmful substances due to the almost complete combustion of the working mixture.
- Insignificant indicators of residual oxygen.
All of these advantages make it possible to obtain the required amount of heat at a relatively low energy cost.

- The boilers are adapted for operation in manual and automatic mode. The use of one or another operating procedure depends on the weather conditions and the preferences of the owner.
- Navien's devices can use not only main gas, but also liquefied gas as raw materials.
- Closed combustion chambers require installation coaxial chimney. This is a huge plus, increasing the safety of operation. To support the combustion process, the equipment uses air from the street, keeping oxygen inside the house.
The heating equipment market is represented by a wide range of products from European, American and Asian brands. Relatively recently, the Korean brand "Navien" appeared on the market, which specializes in the production of reliable and energy-efficient gas boilers and other heating appliances. The quality and functionality of these boilers once again indicates that South Korea is a country of talented developers creating innovative technologies.
The very first gas boiler Navien, which entered the domestic market, received discreet consumer reviews. People noted that the internal elements of the boiler are not reliable enough and are prone to leaks. Taking into account the complaints of users, the company corrected the shortcomings and today Navien gas boilers are a model of durability and uninterrupted operation.
In view of this, the number of consumers of products from the Korean brand has increased, and the manufacturer decided to expand the line of products. If a few years ago, domestic buyers could only purchase a Navien Ace gas boiler whose operating instructions regulated the procedure for using a heating device, today the following options are available on the market - these are atmospheric, condensing and turbocharged boilers.
atmospheric series
The main difference between the boilers of this series is the special design of the open gas combustion chamber. The series combines boilers adapted to difficult working conditions. For example, the Navien Atmo atmospheric gas boiler can operate with low gas pressure in the pipelines and a minimum coolant pressure in the circuit.
In the line of the Korean brand, atmospheric gas boilers Navien, reviews of which you should read before purchasing, are represented by models of various capacities.
Depending on the heating needs, the consumer can install a device with a rated power of 13, 16, 20 and 24 kW in the home.
The specificity of this boiler is the possibility of remote control temperature conditions and the time of work achieved by equipping the boiler with a remote control. It should be understood that the device will work quite efficiently in the heating system if the owner follows certain recommendations - do not fill the circuit with antifreeze, monitor the pressure level in the system, etc.
The operating characteristics of the boiler are presented as follows:
- limiting water heating temperature - 80 ° C;
- Efficiency - 86%;
- working pressure - up to 3 bar.
turbocharged series
This series combines three categories of goods. These are boilers under the brand name Deluxe, Prime and Smart TOK. Each group contains heaters of various capacities, designed to heat rooms with a certain area. For example, the gas boiler Navien Deluxe Coaxial 24k reviews of which are positive character- This is a wall-mounted heater, designed for heating 240 sq. m.
If the Navien Deluxe 24 kW gas boiler reviews, which will help to form an opinion on the efficiency of work, is too powerful for the consumer, he can pay attention to turbocharged boilers with a minimum rated power. This may be a gas boiler Navien 16 kW, the price of which will be more affordable and can vary in the range of $ 250-300. Such a boiler will provide heating for a house up to 120 square meters. m.
The turbocharged gas boiler Navien, whose instruction contains information for consumers, has a number of design differences. It is equipped with a closed combustion chamber, into which air is supplied by forced method. For this, a fan is used, the performance of which is regulated by an integrated controller.
Outdoor air outside the building, with the help of a coaxial chimney and a fan, is forced into a combustion chamber with sealed walls. Thanks to the use of forced air injection technology, the Korean developer has managed to achieve excellent efficiency for all turbocharged boilers. Thus, the minimum value of this coefficient is 92%.
As for the configuration features, any Navien wall-mounted gas boiler with a forced air injection system is equipped with an expansion membrane, a built-in pump to create pressure within the network, and a second heat exchanger. The last element expands the functionality of the boiler and allows the use of a second circuit for supplying hot water used in household needs. How to connect individual heating you can find out in the apartment.
condensation series
Heating devices of this series are distinguished by the greatest efficiency. These include the Navien wall-mounted gas boiler with the abbreviation NCN and NCB. The design feature is that the heat exchanger was developed by the manufacturer with the ability to collect not only active, but also passive heat. The stainless steel heat exchanger installed in the Navien gas boiler reviews about which they talk about high efficiency takes away the latent heat generated during gas combustion.
Unlike turbocharged and atmospheric series boilers, the Navien 24 kW condensing gas boiler, the price of which can reach one thousand dollars, will ensure the rational consumption of resources and open up reserves for savings in the future. Although the cost of the boiler is high, its installation in the heating system will achieve an extremely high efficiency of 98% and reduce the monthly bills for natural gas consumption.
Floor boilers
In a separate group of products in the line of the Korean brand are combined floor standing boilers. At the same time, the manufacturer positions the gas floor-standing boiler Navien as a universal and productive heating device suitable for heating various types of buildings. Specifications floor boilers are similar to those of mounted atmospheric models discussed above.
Smooth operation of boilers from the line
When buying a gas double-circuit wall-mounted boiler Navien for a home, reviews about which speak of consumer satisfaction with the quality of the device, the owner can count on what he is doing right choice. Korean heating technology is produced with attention to the smallest details and is adaptable to work in difficult conditions.
For example, a double-circuit wall-mounted gas boiler Navien, the price of which depends on the power, is equipped with systems that prepare the optimal composition of the gas-air mixture. By getting a certain amount of gas and air into the chamber, the manufacturers allowed the boilers to work more efficiently. A properly prepared gas-air mixture during combustion gives off maximum heat and allows for the rational use of resources.
Korean boilers are distinguished by their compliance with environmental requirements and provide a minimum amount of emissions into the atmosphere during their operation.
They will be a worthy choice for homeowners who want to make their personal contribution to the care of the planet. Consumers should take into account that with the compact dimensions of the body, Korean boilers produce the right amount of heat and spend the minimum amount of gas and electricity for this process.
Advantages of Korean boilers
Modern double-circuit gas wall-mounted heating boilers Navien have a number of advantages. Their list is quite solid and indicates that the consumer can buy a Navien gas double-circuit wall-mounted boiler and use it as the main component of the heating system at home.
The advantages of Korean boilers include:
Disadvantages of devices
In addition to the fact that water can be hard and lead to clogged radiators and valves, the decision to not use antifreeze can lead to more serious consequences - defrosting the system in severe frosts. The manufacturer tried to compensate for this shortcoming by introducing a special option into the boilers. It is represented by a set of devices that prevent the coolant from freezing in the winter.
If we do not take into account this shortcoming, which is not critical for residents southern regions, then the double-circuit gas boiler Navien is characterized by an optimal combination of price and consumer qualities. This device is one of the most worthy offers available on the domestic heating equipment market and can become the basis for designing a heating system for an apartment, a country house or private apartments.
A wide range of boilers, differing in power, efficiency and functionality, allows you to choose heating equipment in accordance with the individual needs of the buyer and the specifics of the room in need of heating.
Double-circuit gas Navien boilers Ace, which are produced by the Korean company Kyung Dong (KD) Navien Co, went on sale in Russia in 2007. Then they were purchased by the first users, and extensive statistics appeared on them, starting in 2008, when gas companies began to install these boilers.
Kyung Dong Navien does not have such a deep history as, for example, Buderus, but has also been on the market for quite some time heating systems– since 1978.
All production of the company is concentrated in three factories in Korea, in other countries there are only sales branches in the company.
Characteristics of gas boilers Navien Ace and Navien Ace ATMO
Gas boiler Navien Ace characteristics (table):
Gas boiler Navien Ace ATMO characteristics (table):
When Kyung Dong Navien entered the Russian market, it faced problems that were previously unknown to Korean engineers, but which are the realities of the Russian space:
- Low pressure in gas pipelines, especially those built on the principle of cooperation.
- Low water pressure in heating systems of private houses.
- Constant voltage fluctuations in the network and outages.
- Poor training of service workers and poor technical literacy of consultants.
In order to level these problems, a boiler was launched on the Russian market, designed to work stably in any conditions - the Navien Ace gas double-circuit boiler.
Gas boiler Navien Ace review
What is this heat generator?
- Firstly, Navien Ace / Navien Ace without the help of a stabilizer holds 30 percent of voltage fluctuations in electrical networks. That is, at a standard 220 volts, Navien Ace can operate in the range from 155 to 280 volts. Such power surges can disable or stop the operation of many boilers.
- Secondly, the minimum gas pressure in the line at which the boiler operates is only 4 millibars, which other boilers cannot boast of. Many competitors shut down already at 13 millibars in the gas line.
- Thirdly, the Navien Ace boiler operates at a water pressure in the heating system of only 0.1 bar, and you can use it even in a private house, even in an urban high-rise building.
- And fourthly, the boiler is equipped with frost protection. If the water temperature in the system drops below +5C, then circulation pump starts to work constantly, circulating water in the system.
Of course, this will not save the house without heating in frosts of -30C, but it will allow you to hold out in a situation where there is a small “minus” outside the window, and help in the form of a service team should arrive tomorrow or the day after tomorrow.
Gas boiler Navien Ace user reviews
Navien Ace gas boiler reviews are collected from real users who operate this boiler in residential homes:
Dmitry Shanin, pos. Chegul, BUT: I use a Navien Ace 30K Coaxial boiler. For some reason, in cold weather, the boiler starts to heat at a set temperature of 60 degrees - from 65 to 80 degrees. In this case, no clocking is observed, the boiler simply heats the water. The temperature outside is 20-25 degrees below zero. As soon as the temperature outside the window drops to -10C, everything is fine, it heats up to the temperature set by the regulator.
There are more reviews about the operation of the Navien Ace gas boiler:
Vladimir Goloduz, Serov: I have been using the boiler for the first year. I heat two floors of 70 sq.m. each. Consumption in cold weather is 18 cubic meters per day. Boiler Navien Ace 24K. For me, it turns out too much gas consumption. Although the boiler does not work all the time, intermittently.
Gas boiler Navien Ace pros and cons
Summing up this boiler, I would like to note the main advantages of Navien Ace - the ability to work at low gas pressure in the gas line and water in the heating system, decent protection against voltage surges and a very attractive price. The average cost of the Navien Ace boiler is 18,000 - 22,000 rubles.
The disadvantages of this gas boiler include the not always adequate operation of automation and minor engineering miscalculations, such as, for example, the indistinct operation of the regulator in the form of a “twist”, which in some versions is replaced by push-button control.

Currently, there are 6 models in the KD Navien product line, which will be discussed in this article.
Prime
Of all the company's products, it is in the Prime boiler that the best innovative technologies are concentrated.
It is designed to organize a heating system and hot water supply. Due to its design, this heater has the following advantages:
The power range for modifications ranges from 13 to 30 kW.
This boiler is almost identical to the Prime, except for the lack of an LCD display.
But despite this, it also has all the advantages of the previous model. In addition, it should be noted the presence of an air pressure sensor (APS), which significantly saves gas consumption during boiler operation. It regulates the power of the air flow generated by the fan. At the same time, the location of the sensor absolutely excludes the ingress of condensate onto its surface.
Also important is a large selection of models depending on the rated power - from 10 to 40 kW.
Ace
Ace series boilers
currently one of the most popular among domestic buyers, if we compare sales volumes with other models.
They also serve to provide domestic hot water and heating the coolant in heating systems. Ace is distinguished by a high degree of reliability and wide functionality.
To ensure the normal operation of the device, the designers took care of the presence of several modes of operation:
- Manual. Allows you to adjust the temperature of the coolant in the heating pipes. Range — from 40 to 80 °С. In this case, in a position below 40 ° C, the so-called summer mode is activated. This can be used not only in summer, but also in case of insufficient water temperature in the hot water supply during especially low temperatures on the street. To take a comfortable shower or bath, you can switch the device to summer mode, thus providing hot water as a priority in heating.
- Auto. Maintaining the temperature in the room from 10 to 40 °C.
- Timer. Possibility to set time intervals of boiler operation (from 0 to 12 hours). At the same time, it works for 30 minutes at set intervals. Heat carrier temperature 80 °C.
Design
In addition to turbocharged designs, Navien also produces heating boilers Atmo from the Ace series with an open burner.
They have the same design advantages as standard models, but are more adapted to Russian operating conditions. In particular, it requires much less effort.
Design
Steel (GA/GTS)
If the issue of hot water is not so relevant, but it is necessary to ensure the normal functioning of the heating system, then the floor-standing boiler from the Steel (GA / GST) series will be the best choice.
Thanks to its narrow focus, it was possible to implement the following functions in its design:
- A stainless steel heat exchanger solves the issue of low-temperature operation, which is very important when connecting the "warm floor" system.
- Small overall dimensions are also an important advantage - the area for its installation is significantly reduced.
- Cleaning of the heat carrier entering the system takes place with the help of a stainless steel coil. This increases the service life of both the boiler itself and the entire line as a whole.
The choice of one or another model of Navien gas heating boilers should be based on the parameters of the existing system. And for this, it is recommended already at the design stage to select all the elements (including the boiler) to optimize the heating operation as a whole.
