Wall-mounted gas boiler Navien. Review of models of gas boilers produced by the Korean company Navien. Atmospheric boilers Navien Ace Atmo

According to reviews, Navien gas boilers do not cause problems to their owners during operation. They are made in Korea, but with a focus on our market. The line includes models with a sealed and non-sealed combustion chamber, as well as with a condensing heat exchanger. All of them are dual-circuit, equipped with programmable microchips and multi-level protection.

Turbocharged boilers Navien Deluxe Coaxial

Deluxe and turbo models differ in the method of connecting the chimney.

The Navien Deluxe gas boiler needs to be hung on the wall, it is double-circuit, the combustion chamber is sealed. This means that it can heat water in two directions at once: heating and hot water. Air for the fire is supplied not from the room, but from the street through. A turbine is installed above the burner to take in air and exhaust gases. It operates from the mains and without it the boiler cannot function.

This heater is designed to work in our conditions. This applies to gas pressure, coolant quality, and harsh Russian winters. This unit has useful feature, which prevents the system from defrosting. According to reviews, this option in Navien gas boilers has saved more than one circuit. When the coolant temperature drops to 10 degrees, it turns on automatically. It circulates the liquid around the circuit so that it does not freeze. If the temperature continues to drop and reaches 6 degrees, then the boiler turns on and heats the liquid to 21 degrees.

The burner is made of stainless steel. Its switching on and off can be adjusted according to the required room temperature. The heater easily tolerates:

• water pressure drop to 0.1 bar;
• gas pressure drop to 4 atmospheres;
• Navien boiler malfunctions associated with voltage surges are excluded.

Heaters of this line are available with a power of 10, 13, 16, 20, 24, 30 kW. Power can be adjusted. The boiler heats water for heating in the range of 40-80 degrees, and for hot water 30-60 degrees. To remove gas combustion products, a 75/70, 60/100 or 80x80 chimney can be connected to the heater.

Turbocharged boilers Navien Ace Turbo Korea

Ace boiler filling Turbo Korea no different from Deluxe Coaxial. That is, both units are dual-circuit and can operate in the same conditions, are equipped with identical systems for maintaining room temperature and preventing circuit defrosting. The combustion chamber is also sealed and works in tandem with the fan. Malfunctions gas boiler Navien during power surges are excluded thanks to a special chip in the microprocessor.

The operation of a sealed combustion chamber is impossible without a turbine.

Two modifications are available with a power of 35 and 40 kW. Naturally, such Navien boilers, according to the instructions, consume more gas. At minimum power, the consumption is 1.48 m3/hour of natural gas, at maximum power – 4.4 m3/hour. In addition, the heater can operate on liquefied gas, in which case the consumption is slightly lower. Main characteristics:

• Efficiency 91.5%;
• minimum power 14 kW;
• minimum water pressure in heating 0.6 atmospheres;
• minimum pressure of the DHW system is 0.1 atmospheres;
• throughput 20.1 or 22.9 l/hour depending on power.

For such units, only the FF 75/70 chimney is suitable - this is one of the main differences between this model and the Deluxe Coaxial. Heater weight 30 kg. The cross-section of the pipes for connecting to the heating system and the central gas pipeline is ¾ inch. ½ inch hot water pipe. Installation of equipment may only be carried out by a specialist with the appropriate level of clearance.

Navien NCN condensing boilers

Condensing boilers are the most modern look heaters for heating. The unit is always assembled from the latest components, so its price is not small. The peculiarity of this heater is its high efficiency, which reaches 98%.

The boiler comes with a remote control.

The combustion chamber closed type. Thanks to the special design of the heat exchanger, the unit is able to heat the coolant or water for hot water supply not only with a flame, but also with the smoke generated as a result of combustion. Combustion products are not immediately discharged into the street, but pass through a special channel where they have time to cool. The temperature of the gases at the outlet of the heater is low, so even plastic chimneys can be used. By the way, the technical characteristics of the Navien gas boiler allow the use of coaxial chimneys 60/100 and 80/125, as well as separate chimneys 80x80.

Useful options:

• frost protection;
• auto diagnostics;
• programmable microprocessor;
• remote control with LCD display.

As the smoke cools, condensation occurs. It collects in the boiler and when its volume becomes critical (about 250 ml), the condensate is simply thrown out through a special pipe. A sewer pipe must be connected to this pipe.

From the remote control you can send commands to the boiler in manual mode, or you can program it to maintain the temperature in the room. In this case, the remote control acts as a remote temperature sensor. The Navien condensing heating boiler is available with a power of 25, 32 and 40 kW. The package includes circulation pump and 6.5 l. All modifications run on natural and liquefied gas. The minimum power for heating is 4.9 and 7 kW, for hot water supply – 4.8 and 6.8 kW. The heater can only operate if the pressure in the DHW system is at least 3 atmospheres.

Atmospheric boilers Navien Ace Atmo

The peculiarity of this line is the combustion chamber open type, into which air enters directly from the room where the unit is installed. All models are dual-circuit, power 13, 16, 20, 24 kW. The boiler is equipped with a processor that prevents the system from defrosting and protects against power surges and pressure drops in the heating, hot water and gasification systems.

Gas boiler Navien 24 kW technical characteristics:

• Efficiency 86%;
• minimum power for heating 9 kW;
• minimum water pressure 0.1 bar;
• minimum DHW pressure 0.6 atm.

Such boilers require a chimney with a cross-section of 130 mm. The diameter of the pipes for heating is ¾ inches, and for hot water and gas ½ inches. The unit runs on natural and liquefied gas. This is a power-dependent device that consumes 110 W/hour.

Updated:

The Navien gas boiler is far from last choice our domestic consumers when purchasing heating equipment. During his presence on Russian market, this Korean manufacturer has managed to gain trust. Therefore, let’s get acquainted with Navien gas boilers in more detail.

Navien boiler range

The Navien company specializes in the production of various heating equipment. But the basis of the entire range is gas boilers.

The main feature of the company’s products is that the Navien gas boiler is perfectly adapted to Russian operating conditions. Here we are talking about problems with centralized water supply, gas pressure surges and unstable voltage in the electrical network. Many foreign models are able to function normally only with ideal conditions. If the same voltage surges, malfunctions may immediately occur. Reviews from buyers of Navien boilers show that malfunctions for them are quite rare.

What gas boilers is Navien ready to offer to its Russian consumers today:

• Wall and floor heating devices;
• Double-circuit and single-circuit models;
• Boilers with closed and open chambers;
• Boilers of a wide range of capacities.

Navien gas heaters are usually distinguished by their performance. The higher the performance, the larger the heated area. Therefore, when choosing a Korean-made boiler, you should focus on floor-standing or wall-mounted models. Condensing boilers deserve special attention.

Wall models

Navien wall-mounted gas boilers feel great among competitors in the domestic market. Their prices start from 30 thousand rubles, which allows the average buyer to become the owner of high-quality boiler equipment.

But when Korean-made wall-mounted models first appeared, the manufacturer encountered some problems:

• The gas pressure turned out to be low. This was especially true for suburban areas;
• Instability in the operation of the water supply system, where the pressure kept jumping;
• Changes in the power grid, which are normal for many regions of Russia;
• There were very few workers capable of servicing and repairing Navien boilers.

Therefore, we had to abandon a number of models and concentrate on the implementation of the Ace series. Ace boilers are distinguished by the fact that they are completely unpretentious to operating conditions and cope well with the problems that the Korean manufacturer had to face when entering the Russian market.

The Ace series of gas boilers has a wide list of advantages, among which we will highlight the main ones.

1. Unique control and monitoring unit. It monitors voltage readings, provides normal work gas equipment even under conditions of a voltage drop of 30 percent below the nominal. Plus, the heating unit can withstand voltage surges of up to 30 percent of the nominal. For them, it is not necessary to buy a UPS with stabilizers. Although for any electrically dependent boiler an uninterruptible power supply will not be superfluous.
2. Steel heat exchanger. Navien use steel stainless heat exchanger, which has excellent heat capacity. This heat exchanger generates thermal energy better, outperforming its copper counterpart. Plus, such a heat exchanger significantly reduces the cost of the design, which has a positive effect on the final cost of the boiler.
3. Frequent malfunctions of boiler installations are caused by a drop in gas pressure in the main. To prevent malfunctions, many manufacturers set a critical pressure threshold at which the boiler turns off. Typically this is 13 millibars. But for Navien this limit is 4 millibars. This allows the equipment to operate even at low pressure.
4. Plumbing faults are not uncommon. Therefore, pressure can change many times during the day. Navien Ase gas boilers have provided for this. The design allows the boiler to operate at a pressure of 0.1 bar.
5. Frost protection. To prevent the coolant from freezing when the heat exchanger is not working, and to avoid malfunctions, the boilers were equipped with an interesting function. When the coolant temperature drops below 5 degrees Celsius, the circulation pump starts. It circulates the coolant through the system, preventing it from freezing.

Floor standing boilers

Navien presented in Russia floor models recently. But now we can talk about a wide range of advantages of this gas heating equipment. The series is called GA/GST.

• Although this is a floor-standing boiler, the dimensions were made compact, not forgetting to equip the body with a combustion chamber, a water heating tank and a heat exchanger. The heat exchanger here is also made of steel with a stainless coating. This heat exchanger is distinguished by excellent performance, and is not much inferior to copper elements;
• The pipes for hot water supply and heating are located on both sides of the boiler. This made the installation process much easier;
• Attractive design. Most floor-standing boilers are installed in separate rooms, so manufacturers don't think much about design. Navien did not make this mistake, making the unit attractive;
• The gas boiler burner operates without any noise. So you can rest peacefully while the boiler is working;
• It is not necessary to build a special chimney if you have an old one. Flue gas can be removed through old systems or through a wall;
• Frost protection works effectively. When the coolant temperature drops to 10 degrees, the circulation pump turns on. And if the temperature reaches 5 degrees, the burner is activated. The heat exchanger heats the coolant, no malfunctions occur;
• A special electronic chip controls voltage surges. At rated voltage 230 V, the boiler can easily withstand surges of 30 percent of the nominal parameters in both directions;
• Floor-standing models of gas boilers from Navien are equipped with remote controls equipped with backlit digital screens. This will allow you in the middle of the night to easily determine how it works this moment boiler and make some changes;
• Additionally, the control panel for Navien floor-standing gas equipment is located on the body;
• As is the case with wall-mounted units made in Korea, floor devices work with main and liquefied gas.

Condensation models

The NCN line from Navien is the newest. It represents a series of condensing gas heaters that are characterized by increased efficiency.

The efficiency of the units reaches 110 percent, which is an impressive figure compared to more experienced competitors.

It cannot be said that condensation models have superiority over their competitors. But Navien definitely keeps up with the times and is not inferior to more famous manufacturers. At the same time, the main advantage is attractive prices.

The Korean company Navien demonstrates that high-quality heating equipment does not have to be expensive. Therefore, one can easily explain the high demand for the products of this company among domestic consumers.

Navien are functional and durable.

When choosing a heating boiler for a private home 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 and the availability of warranty service. And last, but no less significant, is appearance device, its “tuning” and dimensions. If you trace the turnover of heating elements over Lately in the domestic market, we can conclude that buyers prefer European products.

However, this trend is not constant. After all, in last years the Korean company Navien made itself known quite loudly, and gas Navien boilers are able to compete with any European manufacturer.

Advice! The wall-mounted double-circuit gas boiler is especially popular Navien Ace.

This appliance is equipped with an open or closed camera combustion, its functional part is durable. At the same time the price of this equipment lower compared to European analogues, which is the key to the popularity of Navien products.

Characteristics of the Navien Ace line of wall heating devices

Wall-mounted, double-circuit gas appliance heating from the manufacturer Navien, related to Ace line, is represented by the following models: Navien Ace ATMO, Navien Ace TURBO. Wherein latest model presented on the market in two modifications - Korea and Coaxial.

The Navien Ace wall-mounted boiler, regardless of modification, has a power from 13 kW to 40 kW, which allows the equipment of this manufacturer to be placed 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 use in domestic conditions. They can operate at reduced gas pressure in the pipes, significant voltage surges, and retain their functionality even when they are for a long time without switching on, the coolant in the heating system begins to cool down.

In addition, wall-mounted dual-circuit heating elements, Navien Ace TURBO, have other characteristics:

1. this is a double-circuit unit, that is, it is suitable for heating a room and for preparing hot water for domestic purposes;
2. The double-circuit heating device has a steel heat exchanger with a protective anti-corrosion coating. Its cost is several times lower compared to copper analogues. And the insufficient boiler power due to the reduced thermal conductivity of steel is compensated by turbocharging of the gas burner. Today, Navien Ace TURBO can compete in power with devices that have a copper heat exchanger;
3. this gas wall a heating element makes sure that the coolant in the heating system does not freeze. So, when the water temperature in the heating system drops to +10°C, the boilers immediately turn on the circulation pump. By distilling water through the heating system, it prevents the formation of ice crystals. If the coolant temperature drops below +6°C, the gas burner is turned on. It heats the water in the heating system to +21°C;
4. gas units heating Navien Ace TURBO are characterized by economical energy consumption. This is due synchronous work turbocharging systems and air pressure sensor APS (Air Pressure System). The boilers use a pressure sensor to control the rotation speed of the fan under the burner, thereby mixing the gas in optimal proportions with air, which allows the energy carrier to be completely oxidized. Consequently, the efficiency of the equipment increases, but the gas consumption does not increase;
5. These boilers have a long service life, thanks to a reduction in the number of on/off cycles in the event of power surges and low water pressure in the system. So, double-circuit boilers will continue to work if the voltage drops by 30% from 230 V. They will not turn off if the water pressure is 0.1 bar, which is important for houses with autonomous water supply.

Navien double-circuit boilers have two modifications. The Navien Ace TURBO Coaxial gas unit has coaxial chimney. It is useful for those rooms in which it is difficult to ensure air flow for the boiler. That is, the coaxial chimney takes 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 operate even at low voltage.

Navien has developed double-circuit heating boilers that run on gas, but with open camera combustion, that is, without turbocharging. These are Navien Ace ATMO boilers. They feature the same functionality as 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 and system pressure. Gas equipment equipped with a steel heat exchanger. A double-circuit boiler makes it possible to prepare hot water for household needs. However, the open combustion chamber ensures quiet operation, unlike turbocharged boilers.

Navien Ace gas units - their advantages over expensive European models

Gas wall-mounted boilers Navien Ace is affordable.

The first thing that attracts buyers to Navien products is the affordability of the price. But can low cost talk about poor quality, because gas heating units are bought for more than one year. The manufacturer claims no. Their boilers are distinguished by their functionality and durability, and their low cost is ensured by the structural features of the equipment for the heating system.

A steel heat exchanger makes boilers cheap. After all, steel is several times cheaper than copper. And the durability of the steel heat exchanger is ensured by an anti-corrosion coating. At the same time, the heat exchanger consists of two parts, that is, if one part is clogged or broken, there is no need to completely change the part.

Advice! European heating boilers operate in the range of voltage surges of 20 V, when models of Navien Ace gas units do not stop functioning with a voltage surge of 30% in both directions. That is, in the second case the boiler shuts down less, which extends its service life and reduces gas consumption.

The Navien gas double-circuit boiler has remote control with 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 a boiler with a power of 24 kW. And this is a direct saving on energy consumption. It's all about the gas burner control system.

When the consumer turns on the tap hot water, a boiler that previously provided a power of 13 kW now increases it to 24 kW. That is, it also heats hot water, but at the same time does not ignore the heating system. The air temperature in the house remains at the same level.

Like expensive European models, boilers from Navien have 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 operation. Which also helps reduce gas consumption if the temperature outside has risen.

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 to heat household running water for domestic needs. They can operate on natural and liquefied gas.

Gas boilers Navien Prime and Navien Deluxe

Turbocharged boilers are available in a wide power range from 13 to 40 kW. The number in the abbreviation indicates thermal power specific model 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

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.

A coaxial chimney 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 available with maximum power up to 40 kW inclusive, whereas with a coaxial pipe - only up to 30 kW.

Navien Deluxe 24K boiler with channel separator

You can buy an atmospheric boiler if your house already has a chimney, for example, from 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

Design features of Navien double-circuit boilers

1. Navien boilers have two separate heat exchangers: one for heating, the second for running 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 bithermic copper heat exchanger for heating both circuits. Stainless steel itself guarantees a long service life of the gas boiler.

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

3. Electronic board 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 of this brand belongs to a different price category.

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

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.

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.

Navien boiler control unit

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 protective screen made of stainless steel 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

— 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 the technical characteristics, 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.

When choosing heating equipment, every buyer wants to receive a reliable, functional and efficient device adapted to the conditions of the Russian climate. Such units include Navien gas boilers, which are not afraid of voltage surges and are capable of operating in a system with a water pressure of 0.1 bar. Increased demand for relatively young trademark justified by its low cost, thoughtful design, functionality and the ability to use it for heating apartments, houses, office and warehouse premises.

The country of origin of Navien heating boilers is South Korea, but some of the components (mainly gas fittings) are manufactured in Japan. The company has been engaged in the design and production of heating equipment for a short time, but it has quite successfully absorbed the best practices of European companies and introduced its own technologies, offering consumers a high-tech product at an affordable cost.

The largest Korean company Navien is modernizing and expanding its line of gas heating equipment. The main models are presented in floor and wall versions, in three colors: white, gold and silver. Unique technological solutions in the design of heat generators:

• heat exchanger made of stainless steel has an increased service life;
• The SMPS chip installed on the microprocessor guarantees protection against voltage surges within ±30%;
• antifreeze system provides automatic start circulation pump at a coolant temperature below 10 °C;
• a sensor built into the control panel provides control and regulation of the indoor climate;
• Each model is equipped with a circulation pump, water filter and expansion tank.

Types of Navien products

1. Wall-mounted double-circuit gas boilers Navien series Ace are presented on the Russian market in two modifications - with an open (ATMO) and a closed (Turbo) combustion chamber. They can work with priority for hot water supply or heating (at the user’s choice), and are fully adapted to conditions of unstable energy supply - gas, electricity and water.

• Ace ATMO is called the traditional series of atmospheric boilers, which is the best offer from the company in terms of price and quality ratio - the cost of the equipment ranges from 18,700 to 19,200 rubles.
• IN Ace boilers Turbo modulated turbocharging system regulates flow air flow into the combustion chamber so that its quantity is proportional to the incoming gas. At the same time, the productivity of the heat generator increases, and thermal losses and gas consumption are reduced.

You can buy a Navien Ace Turbo wall-mounted gas boiler with a power range from 10 to 35 kW, sufficient to heat an area of ​​up to 350 m2. Two variations of turbocharged heat generators differ in their smoke removal system - the outlet is for a Korean (Korea) or European (Coaxial) coaxial chimney (you can find out what a coaxial pipe is at). The price of Korean boilers of the Ace Turbo Coaxial and Korea series is almost identical and ranges from 20,000 to 25,000 rubles, depending on performance.

2. Floor standing boilers from Navien GA and GST are compact in size. The outlet pipes are located on both sides of the body for the possibility of piping on the left and right, which is very convenient in small rooms.

Each model is equipped with a silent supercharging gas burner, and the smoke removal system provides for the exhaust gases to be discharged both into the existing chimney and through the outer wall.

• The peculiarity of Navien GA is a conventional steel heat exchanger, which has a lower cost. For example, the price of GA-35K is 10 thousand lower than the floor-standing boiler GST-35K with a stainless steel heat exchanger.
• The GST series is structurally similar to the representatives of the GA line, but is a more powerful option stationary generators– from 34.9 to 81.0 kW.

3. The Navien NCN condensing boiler can be called a new generation device: thanks to advanced technologies The design ensures not only efficiency and energy consumption, but also meets all environmental safety requirements. Compared to traditional gas heat generators, when operating in condensing mode, gas consumption is reduced by 30%, and the volume of smoke exhaust is reduced by up to 70%. At the same time, the efficiency reaches 108%.

The built-in digital controller ensures the collection and supply of information, and also conducts self-diagnosis. Due to the low temperature of the gases, the smoke removal system can be installed from plastic pipes.

Description of Navien models

The originally intended efficiency of devices will be realized in practice correct setting geysers Navien, which should only be carried out by specialists.

Comparative characteristics of various Navien boilers:

Main parameters and characteristics for correct selection specified in the operating instructions for gas heating systems:

• Power is an indicator that affects the ability to effectively heat the required area.
• Installation – wall or floor. The installation option depends on required power and availability of free space in the room. On the Internet you can find photos of Navien gas heating boilers with various types canopy (most often in the kitchen).
• Burner type: atmospheric or turbocharged. In the first case, the flame will be constant, and in the second, it will change smoothly and continuously, which ensures more economical gas consumption.
• Smoke removal system - with natural or forced draft. The choice of boiler based on the type of chimney depends on the ventilation of the building.
• Traditional boiler or condensing boiler. Additional thermal energy combustion products allows you to use gas economically, but the cost will be much higher than a conventional gas thermogenerator.

User opinions

“I have been using Navien 24 ATMO since 2009. It takes up little space and provides a stable supply of hot water. The temperature in the rooms is maintained constant regardless of the weather outside, the price is reasonable. It makes a lot of noise - the outer lid slams when ignited.”

Daniil Rudenko, Samara.

“Before purchasing, I carefully studied the description of the Navien 16K wall-mounted boiler and made a choice in favor of this particular model. It is convenient to control the temperature of the heating circuit and hot water supply from the remote control; the modes are supported automatically. The controller system monitors the presence of coolant and pumps it up if necessary.”

Maxim Korzhik, Penza.

“After much thought, I decided to buy a floor-standing boiler GST-40K from Navien - installation was not difficult, but I called specialists to guarantee it. It operates quietly and is easy to operate. I worked for two winters - no complaints. The house is warm and there is hot water. The only drawback is that it is volatile, so we had to install an additional UPS.”

Igor Pankov, Moscow.

According to reviews, Navien boilers are reliable and budget option heating equipment. Competent installation and commissioning works with optimization of the main parameters allow you to use all the functionality of heat generators. The main disadvantages are increased noise when the burner is turned on and the energy dependence of the boiler.
