Popular Models
The time has come to consider the most popular models of Navien gas boilers, in demand among domestic consumers. It is they who deserve the highest ratings from users, providing them with warmth.
The double-circuit gas boiler Navien ATMO 24AN is made according to the traditional convection scheme and is equipped with an open combustion chamber. With a power of 24 kW, it can warm up to 240 square meters. m. of living space, spending up to 2.47 cubic meters. m / h (this is the maximum figure). The DHW capacity reaches 13.7 l/min. The primary heat exchanger is made of copper, the secondary heat exchanger is made of durable steel. If necessary, the device can be reconfigured to work with liquefied gas.
For more convenient control, remote controls with built-in thermostats are connected to the unit (such a remote control is supplied). Inside them, all the necessary piping is provided - these are expansion tanks and circulation pumps. The estimated cost of equipment varies between 23-26 thousand rubles.
Before us is a mounted boiler Navien, created on the basis of a burner with a closed combustion chamber. Unlike the previous model, a clear minus catches the eye - this is a steel primary heat exchanger. If we analyze the reviews of experts, we can find out that copper heat exchangers are the most stable and easy to repair, but equipment with them is more expensive. The power of the presented unit is 24 kW, the capacity of the DHW circuit is up to 13.8 l / min. It is electronically controlled with a diagnostic system and a room thermostat. The efficiency of the device is 90.5%, the cost is 24-26 thousand rubles.
In the line of equipment from Navien, this unit is the most advanced. It is endowed with a closed combustion chamber, an electronic control system, a remote control, a control option via the Internet, a self-diagnosis system, a programmer for operating modes, built-in piping and an outdoor temperature sensor. In other words, this is the most stuffed device from the Korean Navien. Thermal power is adjustable in the range from 8 to 24 kW, the performance of the DHW circuit is up to 13.8 l / min. The efficiency is 91%, the maximum gas consumption reaches 2.79 cubic meters. m/hour. It is possible to operate the device on liquefied gas.

Gas boiler Navien DELUXE 24K
Alexei, 29 years
The boiler was chosen for a long time - before we settled on Navien, we re-read a bunch of reviews and reviews. After numerous consultations with sellers and heating specialists, we settled on this model. All the same specialists were engaged in the installation, he did not dare to do anything. The first winter was successful, there were no breakdowns during operation. Very convenient control - the remote control was placed next to the sofa in the living room. You set the temperature, and the unit standing 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 thinner;
- Low noise level - a couple of times in winter we visited neighbors and heard how their boiler from Baksi was working, rattling and howling with a fan;
- The quick achievement of the set temperature is important after our long business trips, when you enter the house and want to quickly feel comfortable.
Disadvantages:
- The absence of controls on the gas boiler itself, as is implemented in other heating units - in this, specialists from Navien made a mistake;
- Sometimes there is not enough DHW performance - two open taps lead to a decrease 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 fully justified. Friends persuaded me to take a model from Navien, they say, it works perfectly and is inexpensive. I was just finishing the construction of the house and urgently needed heating. I took a double-circuit, and after a year and a half I began to count the number of breakdowns. Not the most reliable device, so I can not advise anyone to buy it. If we are already doing heating, then we need to install an ordinary floor single-circuit with an indirect heating water heater - it will turn out inexpensively and quite reliably.
Advantages:
- It maintains the temperature of hot water well - perhaps this is the only truly positive feature of this gas boiler from Navien;
- No need to buy a harness - everything is already provided inside;
- Self-diagnosis can show errors and failures.
Disadvantages:
- 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 is nonsense, that it was necessary to take a boiler with a copper heat exchanger;
- One of the buttons on the remote control quickly failed;
- The gas boiler from Navien often shows errors that are not actually there - probably the electronics are buggy.
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 units more than densely arranged wall modifications. I was not mistaken in my choice - the gas boiler pleased me with trouble-free operation, the Koreans did a good job. And the performance of hot water supply here is impressive, up to 22.1 l / min - not a single wall-mounted sample 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 the operating modes for the week ahead. Since I am in the city on weekdays, the device operates in anti-freeze mode, saving money in my wallet. By Friday evening, he begins to fill the house with warmth, so my family and friends come to an already warm home;
- Nothing prevents you from simultaneously opening hot water taps in the shower and above the kitchen sink - there is enough performance for all points of water intake;
- It can run on liquefied gas, it helped out a lot in the first year, then a gas pipeline appeared in the village.
Disadvantages:
- For the first year, the Navien gas boiler stood in a small boiler room on the ground floor, but then it had to be moved to the basement - it makes a noticeable noise;
- 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 understandable.
Despite the flaws at the very beginning, further use goes without problems.
Gas boiler Navien SMART TOK 24K
Arkady, 61 years old
The time has come to make a major overhaul in the house, at the same time we decided to modernize the heating system. They threw out all the old pipes, installed modern bimetallic batteries, and at the same time changed the gas boiler by buying a double-circuit Navien with remote control. I was very pleased with the ability to control heating at 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 flawlessly.
Advantages:
- In my opinion, this is the most thoughtful gas boiler - specialists from the Korean company Navien did a good job 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);
- No need to buy a pump and a tank - everything is already inside, without taking up space.
Disadvantages:
- In the very first thunderstorm, the electronics burned out - as it turned out, in gas boilers (of any manufacturer, and not just from Navien), this is the most flimsy place. I had to put additional protection;
- It took a long time to deal with the intricacies of control - in an effort to make the device very flexible in settings, the developers endowed it with a huge number of various 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 with its automation, and you can not pay much attention to the shortcomings. The main thing is to protect the electronics from electrical overloads.

Navien are functional and durable.
When choosing a heating boiler for a private house or an autonomous heating system for an apartment, a person first of all pays attention to the functionality of the equipment and its performance. The second selection criterion is durability, the availability of warranty service. And last, but no less significant, is the appearance of the device, its “tuning” and dimensions. If we trace the recent turnover of heating elements in the domestic market, we can conclude that buyers prefer European products.
However, this trend is not permanent. Indeed, in recent years, the Korean company Navien has declared itself quite loudly, and Navien gas boilers are able to compete with any European manufacturer.
Advice! The Navien Ace wall-mounted double-circuit gas boiler is especially popular.
This device is equipped with an open or closed combustion chamber, its functional part is durable. At the same time, the price of this equipment is lower compared to European counterparts, which is the key to the popularity of Navien products.
Characteristics of the Navien Ace range of wall-mounted heaters
A wall-mounted, double-circuit gas heating device from the manufacturer Navien, belonging to the Ace line, is represented by the following models: Navien Ace ATMO, Navien Ace TURBO. At the same time, the latest model is presented on the market in two modifications - Korea and Coaxial.
The Navien Ace wall-mounted boiler, regardless of modification, has a power of 13 kW to 40 kW, which allows you to place equipment from this manufacturer in rooms of various sizes.
Features and characteristics of Navien Ace TURBO
The Navien Ace gas wall-mounted boiler can be placed in rooms of any size.
The manufacturer claims that Navien Ace TURBO boilers are ideal for domestic use. They can operate at reduced gas pressure in pipes, significant power surges, retain their functionality even when they are not turned on for a long time and the coolant in the heating system begins to cool.
In addition, wall-mounted double-circuit heating elements, Navien Ace TURBO have other characteristics:
- this is a two-circuit unit, that is, it is suitable for space heating, and for preparing hot water for domestic purposes;
- the double-circuit heating device has a steel heat exchanger with a protective anti-corrosion coating. It is several times lower in cost compared to copper counterparts. And the insufficient power of the boiler due to the reduced thermal conductivity of steel is compensated by the turbocharging of the gas burner. Today, Navien Ace TURBO can compete in power with devices that have a copper heat exchanger;
- This gas wall-mounted heating element ensures that the coolant in the heating system does not freeze. So, when the temperature of the water in the heating system drops to + 10 ° C, the boilers immediately turn on the circulation pump. It, distilling water through the heating system, does not allow ice crystals to form. If the temperature of the coolant drops below +6 ° C, the gas burner is already turned on here. It heats the water in the heating system up to +21°C;
- Navien Ace TURBO gas heating units are characterized by economical energy consumption. This is due to the synchronous operation of the turbocharging system and the APS (Air Pressure System) air pressure sensor. The boilers, using a pressure sensor, control the rotation speed of the fan under the burner, thereby the gas is mixed with air in the optimal proportion, which allows the energy carrier to be completely oxidized. Consequently, the efficiency of the equipment increases, but the gas consumption does not increase;
- these boilers are characterized by a long service life, due to the reduction in the number of on / off cycles in case of voltage drops in the mains and low water pressure in the system. So, double-circuit boilers will continue to work if the voltage drops by 30% of 230 V. They will not turn off if the water pressure is 0.1 bar, which is important for houses with autonomous water supply.
Double-circuit boilers Navien have two modifications. The Navien Ace TURBO Coaxial gas unit has a coaxial chimney. It is useful for those rooms in which it is difficult to provide air flow for the boiler. That is, a coaxial chimney draws air for the combustion reaction from outside the building. Korea boilers take air from the room. They work silently.
Features and characteristics of Navien Ace ATMO
Navien Ace ATMO gas boilers work even at low voltage.
Navien has developed double-circuit heating boilers that run on gas, but with an open combustion chamber, that is, without turbocharging. These are Navien Ace ATMO boilers. They are characterized by the same functionality as for turbocharged models. This is an adaptation to domestic operating conditions.
These heating boilers have the same chip, which ensures their constant operation at low voltage in the mains and system pressure. Gas equipment is equipped with a steel heat exchanger. A double-circuit boiler makes it possible to prepare hot water for domestic needs. However, the open combustion chamber ensures quiet operation, unlike turbocharged boilers.
Navien Ace gas units - their advantages over expensive European models
Navien Ace gas wall-mounted boilers are affordable.
The first thing that attracts buyers to Navien products is the affordability of the price. But can a low cost speak of poor quality, because gas heating units are bought for more than one year. The manufacturer claims not. Their boilers are distinguished by their functionality and durability, and the low cost is ensured by the structural features of the equipment for the heating system.
Steel heat exchanger - makes boilers cheap. After all, steel is several times cheaper than copper. And the durability of the steel heat exchanger provides an anti-corrosion coating. At the same time, the heat exchanger consists of two parts, that is, if one part is clogged or broken, it is not necessary to change the part completely.
Advice! European heating boilers operate in the range of voltage surges of 20 V, when Navien Ace gas unit models do not stop functioning with a voltage surge of 30% in both directions. That is, the boiler in the second case is switched off less, which prolongs its service life and reduces gas consumption.
The gas double-circuit boiler Navien has a remote control with a remote sensor.
A gas heating unit from this manufacturer, even with a rated power of 13 kW, will heat the same volume of water as the boiler, with a power of 24 kW. And this is a direct saving on energy consumption. It's all about the control system of the gas burner.
When the consumer turns on the hot water tap, the boiler, which previously produced 13 kW, now increases it to 24 kW. That is, it also heats hot water, at the same time it does not disregard the heating system. In the house, the air temperature remains at the same level.
Like expensive European models, Navien boilers have a remote control with a remote sensor and a liquid crystal display. However, in the first case, the equipment is more expensive, the second option is of Japanese origin, which ensures affordability and durability. The temperature sensor reacts to changes in the atmosphere, sends commands to the burner, which, in turn, either increases or decreases the power of its work. Which also helps to reduce gas consumption if the temperature rises outside.
The popularity of autonomous heating is growing not only among residents of private houses, but also among apartment owners. This trend is associated with the positive qualities of modern boilers, the convenience of their installation and operation.
Among the mass of the proposed range, the demand is high atmospheric gas boiler Navien, we will describe further the principles of operation, the causes of malfunctions and how to eliminate them.
The South Korean association Kyung Dong Navien has long been present in the market of heating and water heating equipment. The main products of the company are gas boilers.
Did you know?Initially, Navien's equipment ran exclusively on natural gas, but over time, models adapted to work on liquefied gas began to be developed.
The corporation firmly holds its leadership in the market due to the fact that each Navien gas boiler is adapted to work under various operating conditions (including in the post-Soviet territory), it has an acceptable price and good technical characteristics. Today the company offers:
- heating equipment for floor and wall mounting;
- models with open and closed combustion chamber;
- double-circuit and single-circuit boilers;
- a wide range of power options.
In terms of the correct choice, Navien boilers should be divided according to power, and therefore - according to the volume of the room. From here comes the division into floor and wall models.
Important! The lower the boiler power, the smaller the heated area.
What are the advantages of Navien Ace boilers
Navien Ace is a double-circuit version of a wall-mounted boiler. It is equipped with an open combustion chamber with a natural release of combustion products. The instructions for their operation speak eloquently about the advantages of Navien boilers - they work even under conditions in which competitors' equipment fails.
Did you know? To increase the service life of Navien boilers, they are made of stainless steel, since stainless steel has a fairly high thermal conductivity.Among the main advantages of Navien Ace boilers, it should be noted:
- universality;
- simplicity of control commands;
- compactness;
- high-quality anti-corrosion material was used in the production;
- fully electronic, Russified control system;
- compliance with high European standards (quality, comfort, safety);
- reliability and resistance to various conditions (voltage surges up to 30%);
- the ability to work in a frankly emergency situation (low pressure of gas and liquid coolant, low-quality gas, unstable pressure in the water supply system);
- economical fuel consumption;
- environmental friendliness (mostly carbon dioxide is emitted);
- acceptable price.
Complete set and principle of operation of the Navien Ace boiler
If we consider the Navien Ace wall-mounted atmospheric gas boiler from the technical side, then this model cannot be called simple. This is, in fact, a mini-boiler room, which includes:
- circulation pump;
- automation block;
- universal separate heat exchanger;
- expansion tank;
- various shut-off valves.
Since most models of wall-mounted boilers use a closed combustion chamber, they are equipped with turbocharging and a coaxial (pipe-in-pipe) chimney.
The power of Navien Ace boilers depends on the model and varies between 7-40 kW. True, there are no special differences in the principle of operation of the Navien boiler - it operates according to the classical scheme, which uses a combustion chamber, burner and heat exchanger.
Important! The APS mechanism, on the basis of which the double-circuit version of the Navien boiler operates, ensures uninterrupted combustion and gas savings. A speed-controlled fan ensures safe combustion.The most popular models of wall-mounted boilers Navien Ace
The most reliable Navien boilers, the operation of which can only be found positive reviews, are distinguished by an optimal price-quality ratio. They are divided into two categories:
- Ace ATMO. Traditional boiler with an open combustion chamber. Equipped with atmospheric removal of combustion products.
- Ace TURBO. Advanced boiler equipped with a turbocharged burner and a special SMPS control system that regulates the process of gas combustion.
What to look for when installing Navien Ace boilers
Since detailed Russified instructions are attached to the Navien boiler, there are no special problems with its installation and launch - you can mount the equipment yourself.
However, experts advise paying attention to the combustion products removal system. They can be discharged through a standard chimney or installed as a separate structure. If the indicated methods of exhaust gases are not suitable, a coaxial chimney can be installed.
The most common malfunctions and elimination of problems in the operation of the boiler
With its functionality and provision with electronics, there are certain disadvantages and malfunctions that can be encountered during the operation of the Navien Ace boiler.
Most often, users are faced with a problem when the unit stops working, and the electronics signal a critical error. This situation can be caused by various factors, including the sensitivity of the sensors. The most common mistakes:
- Smoke removal. Fault code "10" indicates problems with the removal of combustion products. Possible causes: turbine malfunction, pressure sensor tubes are not connected correctly, the chimney is clogged, the nozzle is too long.
If none of these causes are identified, and the Navien Ace boiler continues to signal an error, then normal gusts of wind may be the cause. You can solve this problem by redoing the chimney. As a quick response option, you can open the boiler body and disconnect the air supply hose. However, this measure is temporary.
For common mistakes on the Navien gas boiler, see this video:
Important! The manufacturer recommends installing boilers with the chimney exit on the leeward side.
- Flame sensor failure. Fault code "03" may indicate poor gas quality. The problem can only be solved by elimination. First of all, the cleanliness of the gas supply nozzles is checked. If they are in order, you need to choose the optimal position of the controller electrode (it must be in the hot phase of the flame).
- Equipment overheating. Fault code "01". A possible cause is a blockage in the heating system, a malfunction of the circulation pump, or a decrease in flow. Ways to solve the problem: check the system and filter for the presence of air, check the health of the pump and the resistance of the coil for a short circuit, check the impeller in the circulation pump.
- Navien gas boiler is working, There is heating but no hot water. Error code "02". There is a jump in water temperature on the remote control (it rises sharply to a maximum and instantly drops). Perhaps there is a blockage in the hot water system. The reasons may be: lack of pressure in the water supply system, airiness of the system, the circulation pump cannot gain momentum, the distribution valve is closed, or the flow controller does not work. To eliminate this malfunction, first of all, it is necessary to adjust the pressure, bleed the air in the system, check the resistance of the pump coil and the impeller for damage, open the boiler distribution valve, disassemble the regulator housing and clean the box.
In addition, when hot water is turned on, the Navien boiler may hum or make an incomprehensible noise. At the same time, there is no error information on the display and the pressure is normal. As a rule, this is due to clogging of the heat exchanger. To fix the problem, you can clean the heat exchanger or replace it.
Did you know? It is best to choose boilers that are equipped with smooth adjustment - this will allow you to change performance depending on the air temperature.Navien Ace gas boilers are distinguished by high quality and reliability in operation. However, the duration and features of operation depend on how correctly you were able to install and configure the Navien Ace boiler, as well as on the quality of the fuel used.
In the Russian market of heating equipment today there are many different types, brands and models of boilers. You can choose them according to various parameters, but if the main thing for you is the optimal price-to-quality ratio, along with high power parameters, then we can recommend Navien heating boilers, which are quite popular today.
Equipment Features
Despite the fact that there are many varieties of Navien boilers, they all have several similar parameters:
- long service life;
- high quality workmanship;
- the presence of a two-circuit system that allows Navien boilers to provide not only heating, but also the supply of hot water;
- low cost, which is difficult to find from another manufacturer;
- high efficiency of any Navien boiler, depending on the type of a particular model, but always above 90%.
In addition, all Navien boilers are designed for operation specifically in Russian conditions and can easily withstand both low pressure in the gas supply network and power outages.
Features of choice
If you decide that the Navien heating boiler will be installed in your home or office, you should consider the following characteristics of such equipment to select a specific model:
- performance, which can be equal to 60 kW (for a Navien diesel boiler), or be at the level of only 13 kW. Thus, you can choose a unit that will provide the most efficient heating of your home, office or other premises without unnecessary energy costs;
- need for hot water. If you do not need hot water too often, you should pay attention to Navien Ace gas-fired and wall-mounted models. With their help, you can get a flow rate of about 10 l / min, which is enough for the operation of 1-2 water distribution devices (faucets, showers, etc.). A significant amount of hot water for household needs can be provided by the diesel-type Navien boiler, which supplies it with a flow rate of up to 34 l / min.
Purchase of boilers
You can buy a Navien boiler from one of the dealers of this brand in the Russian Federation. For example, in the TeplovodService company, which offers its customers many advantages - from relatively low prices to high-quality service for all Navien boilers. In addition, everyone who decides to buy Navien is issued a branded warranty card that allows them to apply for repairs and maintenance for as long as 3 years.
As you know, gas heating equipment is the most profitable and safe option for heating premises for various purposes. The same applies to the products of the famous Korean concern Navien. A gas boiler of this brand will not only serve you for a long time (at least 15 years), but will also be the most profitable investment for heating your home, office or store.
Equipment Features
Among the features of Navien wall-mounted gas heating boilers, the following are worth noting in the first place:
- minimal emissions of harmful substances into the atmosphere. This is achieved through high-quality assembly and the use of the most modern technologies, and for the Ace Coaxial series - also with the help of a closed combustion chamber design, which also increases the efficiency of Navien gas boilers (efficiency > 92%);
- a high level of automation of all processes of operation of Navien gas boilers. This includes automation that regulates the parameters of the coolant depending on the external microclimate, and protective systems that prevent the occurrence of emergencies (freezing, overheating, etc.);
- relatively low cost of the Navien Ace boiler itself, as well as its operation;
- the minimum required pressure parameters in gas and water supply systems, which is especially important in the conditions of operation of the Korean gas boiler Navien in our country.
Features of choosing a boiler
Before deciding which wall-mounted Navien gas boiler you need, you should pay attention to the following factors:
- the amount of hot water that you need, as well as the area of \u200b\u200bthe rooms that require heating. The performance line of the Navien Ace series boilers includes units with capacities from 13 to 30 kW. This allows you to heat, respectively, 130-300 "squares" (although the minimum dimensions of an efficiently heated room for units are approximately 65 square meters) and provide hot water with a flow rate of 8-23 l / min;
- possibility of installation in a heated room or a chimney building. If such a chimney already exists or its manufacture is not difficult, you can choose the less expensive Navien Ice models of the Atmo series. Difficulties with the device (lack of space, high ceilings, etc.) automatically make it possible only to use Navien Ace gas boilers of the Coaxial type;
- room color scheme. If it matters to you, boilers can be purchased in gold, silver, or plain white.
Purchase of appliances
It will be most profitable to buy all this equipment from the TeplovodService company, which is not only the official (and, therefore, giving a full guarantee) supplier of the brand, but also provides its customers with the highest quality service and the lowest prices for all the equipment presented.
