Gas boilers navien ace turbo. Gas boilers "Navien" (Navien). Characteristics, review, reviews. The most popular models of wall-mounted boilers Navien Ace

Wall-mounted gas double-circuit boiler NAVIEN Ace 13-40 kW

Gas equipment, which is used to create autonomous heating systems, has been most in demand over the past few decades in those places where there are gas distribution lines. For the installation of this type of heating in apartments of multi-storey buildings or cottages, navien gas boilers are one of the most suitable options. The products of this brand appeared on the domestic market not so long ago, but they quickly won the loyalty of customers.

Navien is a company belonging to one of the largest companies in South Korea. She is engaged in the production of universal power engineering for use in everyday life. And the boilers of this brand are practically in no way inferior to the products of world leaders in the production of equipment for autonomous heating. Among the large range of products, a special place is given to double-circuit wall-mounted boilers, which are easy to use and have a long service life.

Advantages and disadvantages of equipment

Like any other heating equipment, Navien gas heaters have an extensive list of advantages:

• All models are economically justified, given that gas is currently the cheapest and most efficient energy carrier.
• Double-circuit wall-mounted boilers are environmentally friendly appliances, since only carbon dioxide is emitted into the air, which is absorbed by green spaces.
• Gas-fired equipment is fully automated, so it can operate for a long time according to a given program.
• The technologies used in the production of Navien boilers provide long service life without periodic service checks.
• Affordable and simple controls make working with products from Korea easy and as comfortable as possible.

Among the minuses of Navien equipment, only the constant need for power supply can be noted.

Therefore, in order to protect yourself from problems associated with power outages and surges in the network, you should use various stabilizers with built-in or plug-in batteries.

Design features and principle of operation

Navien double-circuit boilers operate according to the standard scheme for this type of equipment. The heat exchangers of the unit are heated by absorbing the heat generated by burning the gas. The circulation of water and coolant is carried out using a pump built into the boiler system.

Air is forced into the combustion chamber through a built-in ventilation system. It takes oxygen through a chimney mounted in a model with a closed firebox.

To increase the duration of operation, navien wall-mounted boilers are made of stainless steel. It is reliably protected from corrosion and withstands long-term thermal loads, as well as sharp thermal shocks.

Boiler design

Of course, the cost of dual-circuit units is significantly higher than the price of a single-circuit device. But do not forget that with the help of the Navien boiler, not only heating in the room is provided, but also the supply of hot water.

The wall unit includes the following items:

• Frame.
• Circulation pump.
• burner.
• Heat exchanger.

The connection scheme for such a unit is extremely simple - during the installation of a wall-mounted boiler, it is quite enough to simply connect all the pipes to the mounted mixers, and then bring them to the entrance to the heating system.

All modern Navien models differ from each other in the device of the burner. If these are open-type devices, then they provide for the mandatory supply of a chimney that operates on the principle of natural draft. For the burner, oxygen is taken directly from the room in which the wall-mounted boiler is located. Therefore, the owner will have to ensure an uninterrupted supply of fresh air.

The design with a closed burner provides for the presence of a coaxial chimney through which oxygen is supplied, as well as combustion products are removed. This type of system is activated by creating forced draft through a vent between two pipes of a coaxial chimney, which is led through the wall to the street. At the same time, the structure is located at the height of the boiler itself, about one and a half meters from the floor level, which is more economical than a natural draft chimney.

The most popular models of wall-mounted boilers Navien

Boiler NAVIEN Ace TURBO Coaxial

All models of double-circuit gas boilers of the Navien brand have both pluses and minuses. In order to understand at least a little about each line presented by the manufacturer, you should familiarize yourself with their characteristics.

Navien gas appliances are available in three colors - white, silver and gold. Their main advantage is their compact size and aesthetics, thanks to which the boilers can be installed in any interior. The Navien Ace range is ranked by instrument power, which ranges from 9 to 35 kW.

All products are equipped with a special system that prevents the coolant from freezing. To do this, the design provides a sensor responsible for starting the pumps when the temperature drops to +10 degrees.

Now more about each presented series:

• ATMO - gas boilers are equipped with a convenient system of natural removal of the resulting vapors. The design of such a unit was created to work in harsh conditions with significant gas pressure drops or fluctuations in the gas pipeline. The power of products in this series ranges from 9 to 24 kW, depending on the model. Such power is enough to heat the coolant in the heating system up to +80 degrees and hot water up to +60 degrees with an intensity of its use of 10 liters per minute.
• HSN - this model range is the most modern achievement of the manufacturer Navien. The efficiency of such boilers can reach 110%. Such indicators are the result of using the temperature of the vapors emitted through the chimney. The heated moisture of the condensate is collected in a heat exchanger, which heats the incoming water flow. In addition, the boilers of this model range are equipped with a condensate collection system, which contains a minimum of harmful emissions. The devices provide a system for regulating the power of work, and hence the control of the heating of the coolant.
• Ace Coaxial - wall-mounted boilers of this series have all the advantages of Navien units. They are easy to operate, have a high degree of reliability and significant efficiency. For maximum ease of use, all devices are equipped with a wide LCD display that displays the technical information of the device. For remote control, the unit is equipped with a remote control with a built-in temperature sensor. This makes it possible to automatically change the settings of the boiler, depending on the microclimate in the room where the remote control is located.

About installation

Installation Features

Installation of all models of wall-mounted double-circuit gas boilers Navien is a simple and simple procedure. After all, detailed instructions are attached to each unit of this manufacturer. Therefore, all work on its installation can be carried out on its own or by specialists from companies offering heating installation services.

But do not forget that the installation of a gas heating boiler is associated with various activities that are carried out only by specialists who control gas consumption. In any case, you will have to invite a gas company employee to conclude a service contract and obtain a permit to operate a gas boiler. Otherwise, high fines cannot be avoided, up to a ban on using a gas installation.

An important point that should be taken into account is the need for a rational choice of a gas removal system. In most cases, for the operation of wall-mounted boilers of the Navien brand of all modifications, an inexpensive, but at the same time incredibly efficient coaxial chimney can be used. Installation of the exhaust system can be carried out not only vertically, but also horizontally.

Conclusion

Navien wall-mounted gas boilers are made in Japan and Korea, which is a guarantee of their reliability and impeccable quality. They have several control modes, a remote control in Russian and many other little things that make the operation process easier. It is very important that even with power fluctuations the equipment works flawlessly, safely and according to the highest quality standards.

Each buyer, when choosing heating equipment, wants to get a reliable, functional and efficient device adapted to the conditions of the Russian climate. These units include Navien gas boilers, which are not afraid of voltage drops and are able to operate in a system with a water pressure of 0.1 bar. The increased demand for a relatively young brand is justified by the low cost, thought out to the smallest detail design, functionality and the possibility of using it to heat apartments, houses, offices and warehouses.

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 recently been engaged in the design and manufacture of thermal equipment, but quite successfully incorporates the best practices of European companies and introduces its own technologies, offering consumers a high-tech product at an affordable cost.

The largest Korean company Navien modernizes and expands the range of manufactured 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:

• a heat exchanger made of stainless steel has an increased service life;
• the SMPS chip installed on the microprocessor guarantees protection against power surges within ± 30%;
• the anti-freeze system automatically starts the circulation pump at a coolant temperature below 10 °C;
• a sensor built into the control panel provides control and regulation of the climate regime in the room;
• each model has a circulation pump, water filter and expansion tank.

Varieties of Navien products

1. Wall-mounted double-circuit gas boilers Navien of the Ace series are presented on the Russian market in two modifications - with an open (ATMO) and a closed (Turbo) combustion chamber. They can work with priority on hot water supply or heating (at the user's choice), fully adapted to the conditions of unstable supply of energy carriers - 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 - the cost of equipment ranges from 18,700 to 19,200 rubles.
• In Ace Turbo boilers, a modulated turbocharging system regulates the air flow into the combustion chamber so that its amount is proportional to the incoming gas. At the same time, the performance of the heat generator increases, while thermal losses and gas consumption decrease.

You can buy a wall-mounted gas boiler Navien Ace Turbo with a power range from 10 to 35 kW, sufficient to heat an area up to 350 m 2. Two variations of turbocharged heat generators are distinguished by a smoke exhaust system - an outlet for a Korean (Korea) or European (Coaxial) coaxial chimney (you can find out what a coaxial pipe is by). 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. Outlet pipes are located on both sides of the body for the possibility of tying on the left and right, which is very convenient in small spaces.

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

• A feature of Navien GA is a conventional steel heat exchanger, which has a lower cost. For example, the price of a GA-35K is 10,000 less than a GST-35K floor standing boiler 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 for stationary generators - from 34.9 to 81.0 kW.

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

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

Description of Navien models

The correct setting of Navien gas water heaters, which should be carried out only by specialists, will allow to put into practice the initially laid down efficiency of the devices.

Comparative characteristics of various Navien boilers:

The main parameters and characteristics for the correct selection are indicated 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 the required power and the availability of free space in the room. On the Internet you can find photos of Navien gas heating boilers with various types of canopy (most often in the kitchen).
• Type of burner - atmospheric or turbocharged. In the first case, the flame will be constant, and in the second, it will change smoothly and continuously, which ensures a more economical gas consumption.
• Smoke exhaust system - with natural or forced draft. The choice of boiler according to the type of chimney depends on the ventilation of the building.
• Traditional boiler or condensing. The additional thermal energy of the combustion products makes it possible to economically consume gas, 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, stable hot water supply. The temperature in the rooms maintains a constant regardless of the weather outside the window, the price is reasonable. It makes a lot of noise - when ignited, the outer lid slams. ”

Daniil Rudenko, Samara.

“Before buying, I carefully studied the description of the Navien 16K wall-mounted boiler and made a choice in the direction 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 system of controllers monitors the presence of coolant and, if necessary, performs pumping.»

Maxim Korzhik, Penza.

“After much thought, I decided to buy a GST-40K floor-standing boiler from Navien - the installation was simple, but I called specialists to guarantee it. Quiet operation, easy operation. Worked for two winters - no complaints. The house is warm and there is hot water. The only drawback is that it is volatile, I had to install an additional IPB. ”

Igor Pankov, Moscow.

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

The Navien gas boiler is a profitable purchase in the light of a sharp rise in the price of imported heating equipment. Korean heaters are 30-40% cheaper than European counterparts. At the same time, they are in no way inferior to the "Europeans" in build quality and reliability.

About company

Korea has long been famous for high-quality electronics and household appliances, and heating equipment is no exception. NAVIEN is a giant enterprise specializing in the production of gas and diesel fuel boilers. Components are made in Korea and Japan. Assembly - only in Korean factories. Previously, the company supplied its products to the US and Pacific markets. Since 2007, promotion to the European markets has begun. Today Navien actively supplies its goods to Russia.

Most common problems

Often the causes of malfunctions are the poor quality of the coolant or gas. Error codes help to cope with solving problems. Here are the most common malfunctions that can happen with Korean gas equipment:

• Overheating.
• No flame signal.
• Fan defective.
• Control board failure.
• Short circuit in the flow sensor circuit.

Error codes

Despite the saturation with electronics, Korean heaters are functional, like any technique, they can break. Start-up and operation do not always go smoothly - malfunctions may occur in the process, and numbers appear on the display - error codes. The decoding of the codes can be found in the user manual. Frequently encountered problems:

• Error "01". May occur due to clogging of the system or malfunction of the pump.

• Error "02". The flow sensor of the heating system has tripped. There are several reasons:

- air has entered the system;

- the filter for the coolant at the inlet is clogged;

— there is a leak;

- the sensor is broken.

With error "02" hot water disappears. The temperature of the water rises sharply and immediately drops. It is likely that there is an airlock in the DHW system. It appears due to low pressure, poor operation of the circulation pump, breakdown of the flow controller. In this case, you need to adjust the pressure and bleed air from the system.

• "03". The flame sensor worked - he "did not see" the fire. Causes:

— low gas pressure;

- ignition electrodes are dirty;

— poor quality of gas;

- the sensor is broken or the electrical circuit that conducts its signal is broken.

• "ten". Combustion products are not properly discharged. Causes:

— the turbine is broken;

- the pressure sensor is connected incorrectly;

- clogged chimney;

- excessive pipe length.

It happens that there are no problems with the chimney - perhaps the signal is caused by gusts of wind. Then the reason is in the chimney - you need to redo it. To temporarily remedy the situation, you can remove the air supply hose. But this is only done as a temporary measure.

All Navien modifications are reliable, but the duration of their operation largely depends on how the installation was carried out, how the maintenance is carried out and whether the settings are set correctly.

Differences between Navien and analogues

The Korean manufacturer is among the few that use their own developments. The brand does not release modified and slightly improved versions - each new modification is worked out to the subtleties. Among the structural advantages it is worth noting:

• Remote control via iOS and Android systems. This is for SMART TOK series.
• Modulating burners. Quiet operation depends on them, they are responsible for maintaining a comfortable temperature for a person.
• Thanks to voice prompts, the operation and configuration of the devices is simplified. If the user is not well aware of how the device works, voice prompts and error codes will help him.
• Corresponds to our conditions - a possible decrease in pressure, power surges in electrical networks, pressure drops in gas pipes.
• Self-diagnosis. The device itself determines its “diseases” and notifies the user about them by displaying an error code on the display.

The Korean manufacturer, taking into account possible risks, has created safe and easy-to-use equipment. If you take an interest in the statistics of reviews, it becomes clear that consumers have managed to evaluate the quality of heat exchangers and burners, as well as the uninterrupted operation of Korean heaters. Only 2% of buyers turn to service centers, and even then, the causes of problems are usually incorrect connection or operating errors. In order for the boiler not to create problems, you need to connect it correctly and set it up correctly. It is also important to know how to use gas equipment - for this, instructions are attached to each piece of equipment. The kit also comes with a passport and a wiring diagram.

Advantages

The brand positions its heating equipment as optimal according to the "price-quality" formula. Boilers "Navien" can be used for heating a private house, apartment, industrial premises. Their advantages:

• Resistant to voltage drops. Its jumps often lead to equipment failure. The Koreans provided reliable protection - they installed a Switched-Mode Power Supply control chip - it expands the voltage range to 165-300 V.
• Resistant to reduced gas pressure. Many modifications refuse to work because of this, but not Navien - they continue to work at the lowest values.
• Nice, ergonomic design.
• Any Navien boiler is double-circuit. So, in addition to heating, its owner receives an addition in the form of hot water supply.
• A wide range of capacities is offered - you can choose an option for any room.
• Equipment owners can always get professional help at the service center. Contact details can be found in the attached documentation.

Are there any downsides?

• The cost compared to Russian counterparts is higher.
• We have to look for - in case of breakdown - imported components.
• Need regular maintenance.

But these shortcomings can be challenged. By paying more, you get a reliable device, forgetting about unstable operation and other shortcomings inherent in many domestic boilers. With spare parts, the issue is also solved simply - they can be ordered at authorized Navien centers. And, finally, regular maintenance - so without it, not a single equipment will last long.

How to turn it on?

There are two ways to turn on the device:

• Remote control.
• Using the buttons on the control panel - you just need to press "Power".

After starting, the device starts working in the specified mode - which was set earlier. To change the settings, you need to use the manual, and set the modes correctly. Before starting the device, it is installed, connected to engineering networks, the heating system is filled with coolant - following the pressure gauge.

Model overview

Many users initially gave negative feedback about Korean boilers. Causes - leaks in the connections. They had to be eliminated by replacing the gaskets - you need to buy a rather expensive kit. The second flaw was associated with a belated start of the burner - the coolant had time to cool down more than necessary. But the company corrected the shortcomings, today there are practically no such accusations against Navien. The brand produces hanging heaters of three types:

• atmospheric;
• condensation;
• turbocharged.

The consumer can purchase a gas boiler:

• Single circuit or double circuit.
• Wall or floor. The latter are more bulky and require a separate room.
• With open or closed combustion chamber.

The widest range is in the line of mounted models. It is these devices that are in the highest demand among the Russian consumer.

Navien Atmo 24AN and others

The atmospheric wall-mounted device Navien Atmo replaced the less successful modification of Ace. It can operate at extremely low fuel pressure - 8 mbar, and water - 0.6 bar. There are 4 models of different power in the series - 13, 16, 20, 24 kW. The heat exchanger for heating is made of copper. For hot water - stainless steel. Automatic control. There is a remote control. There is frost protection. Specifications:

• 24 kW.
• Water heating in the heating system - 80 ° C.
• The pressure in the circuit (maximum) - 3 bar.
• Efficiency - 86%.
• The maximum water temperature in hot water supply is 60 °C.
• Weight - 27 kg.
• Estimated cost 26-27 000 rubles.
• Heating area - 240 m².

Important! The system can only be filled with water - antifreeze is prohibited.

Deluxe 24K and other turbo modifications

The line of turbocharged modifications is represented by three series of Deluxe (13-40 kW), Prime and Smart TOK (13-35 kW) at once. Navien Ice Turbo is an outdated model, it was replaced by Deluxe and Prime devices. Forced heaters have a closed firebox, and air is forced into it - by a fan. The performance of the fan is controlled by the controller. In order for air to enter the chamber, a coaxial chimney is organized. Due to forced injection, turbocharged modifications are characterized by increased efficiency.

There are no more differences between turbocharged and atmospheric versions. The equipment is completely similar - an expansion tank, a pump, an additional heat exchanger.

The Prime series, like the Deluxe Coaxial, has a closed firebox and all the usual elements of a turbocharged model. But Prime has an additional module - weather-dependent automation. Characteristics of the 2-circuit wall-mounted boiler Deluxe 24K:

• Efficiency - 90.5%.
• 24kW.

auto ignition.

• The maximum heating area is 20 m².
• Consumption of natural gas - 2.58 m3 / h.
• Dimensions (WxHxD) - 440x695x265 mm.
• Weight - 28 kg.

NCN 40KN and other condensing models

The principle of operation of the condensing heater is based on the use of both direct and latent heat released during gas combustion. This allows achieving high efficiency values ​​- more than 100%. Condensing heaters are available in the Navien NCN and NCB models. Their heat exchangers are made of stainless steel. The package is similar to the turbocharged versions. The difference is that the functions of the controller are expanded. For example, he can program work for the next seven days. NCN is represented by 4 boilers 21-40 kW, NCB also 4 models 24-40 kW. Air is supplied forcibly - through a coaxial or separate chimney. For example, the characteristics of NCN 40KN:

• 40.5 kW.
• Two contours. Wall mounting.
• Closed furnace.
• Auto ignition.
• Weighs 38 kg.
• Efficiency 107.4%.
• The maximum heating of water in hot water supply is 65 °C.

LST 30 KG and other floor models

The brand presents a line of floor-standing boilers of four series - LST, LFA, GA, GST with a capacity of 13-60, 13-40, 11-35 and 35-60 kW, respectively. Each of the presented samples is a universal outdoor apparatus capable of operating both on natural gas and on diesel fuel. Floor versions, no less than wall-mounted ones, are saturated with automation. For example, the characteristics of LST 30 KG:

• 90% efficiency.
• Weight - 45 kg.
• 30 kW.
• Heated area - 300 m².
• Auto ignition.
• Volatile.

How does Navien Ace TURBO work?

For example, consider the description of the operation of a turbocharged heater. Such a device is not afraid of low fuel pressure or power surges. It will heat any area. Along the way, it heats the water - there is a second circuit. DHW heat exchanger - steel. It is much cheaper than copper counterparts. Lack of power - due to insufficient thermal conductivity of steel, can be compensated - turbocharging of the burner helps. Such devices easily compete with analogues with copper heat exchangers.

The turbo heater monitors the temperature of the coolant - if it drops below plus 10 degrees, the circulation pump turns on. It drives water, preventing ice crystals from forming. When the temperature drops below plus 6 degrees, the burner will light up - it will heat the coolant to +21 degrees.

Turbocharged devices are available in two versions, the second - with a coaxial chimney "Navien Ice Turbo Coaxial". It is advantageous to put it in rooms where it is impossible to ensure a normal supply of oxygen. A coaxial chimney takes air from the street.

What could be nicer than the hugs of a loved one? Once in them, we leave all worries and problems behind. The peace and warmth that they radiate calms and gives strength to fight on. All this is impossible without home comfort, where the whole family realizes its importance and members can express their gratitude to each other. Especially in winter, I want to come to a warm home. But this is not possible without a heating system. The latter should be not only reliable, but also cheap to maintain. Also, the price of the main modules should not skyrocket.

The central component for heating systems is a gas boiler. You can find hundreds or even thousands of offers in conventional or online stores. Models of domestic and foreign production are presented. Due to the increase in prices, the latter is becoming increasingly difficult to buy. But there is an option that is ideal in almost all criteria - this is a double-circuit gas boiler "Navien". He will become a hard worker and a reliable assistant.

Advantages and disadvantages

A balanced assessment of any case is very much appreciated. It allows you to achieve the desired result and incur the minimum amount of costs. This approach is also relevant when choosing Navien double-circuit gas boilers. This brand positions its gas boilers as excellent value for money. The strengths include the following:

The disadvantages of such gas boilers are much smaller and for many they will be insignificant:

• the price is higher than that of domestic counterparts;
• imported spare parts;
• the need for regular maintenance.

In most situations, it is better to overpay than to subsequently suffer from unstable functioning and other shortcomings. The required components will be delivered on time through authorized Navien centers, and without regular maintenance, any device will sooner or later end up in a landfill.

The lineup

Double-circuit gas boilers "Navien" are represented by several lines. Each of them has its own specific features that may be required for a particular dwelling. It will be useful to consider each of them separately.

Atmospheric line "Navien" Ace ATMO

Double-circuit boilers of this model range were developed for the most unstable conditions, so they are as unpretentious as possible. The compartment where gas combustion takes place is open. Therefore, when installing such a heating boiler, you will have to take care of a properly designed chimney that will have the required draft. Gas appliances of this subsection are ready to work even at a gas pressure of 4 mbar. In winter, this can be very helpful. The fact is that in houses where a large number of gas boilers are installed, the supply rate can drop sharply when the temperature outside creeps down. But with such a boiler from Navien, you can forget about troubles.

If trouble does not come alone, and along with the blue fuel supply indicator, the water pressure also drops, then for Navien wall-mounted gas appliances, everything is nothing. The voltage stabilization system mentioned above perfectly tolerates the instability of the power supply. In the event of any unforeseen situation, the wall-mounted boiler will conduct an independent analysis and display an error code on the control panel. Some are easy to fix on their own. Are you planning to leave home and leave no one to control? Do not worry about freezing protection in wall-mounted gas boilers, everything will be done for you.

It is easy to adjust the temperature of the Navien boiler in the heating system within the range of 40º to 80º Celsius. Even the most heat-loving will be satisfied. For hot water supply, this figure is in the range from 30º to 60º. The liquid transfer pump in a double-circuit wall-mounted boiler has an automatic air sensor that will immediately reset it.

Note! Navien boilers of this type can easily operate on both natural methane and liquefied gas, so even in the absence of a centralized supply, it will be possible to power it. For the transition, it is enough to use a special kit. Models of gas boilers are available whose power starts from 13 kW, and the maximum value is 24 kW.

Range with Navien Deluxe Coaxial turbine

Double-circuit wall-mounted boilers of this line are in many ways similar to the previous ones. They also tolerate various differences in gas and water lines. These "Navien" double-circuit boilers also cope with power surges perfectly thanks to the SMPS chip. Such boilers are equipped with a remote control with a sensor for better control. But they also have certain differences.

The combustion chamber in these wall-mounted boilers is closed, so a different system is used to supply air and remove exhaust. A special turbine is mounted directly under a specialized compartment of a double-circuit boiler. It forcibly pumps the volume required for high efficiency and complete combustion of the fuel. This boiler system is modulating. The atmospheric pressure sensor monitors its value and controls the fan speed. The lower the pressure, the higher the rotation of the turbine of the double-circuit boiler, so that there is no power loss. There is no need for massive shafts to eject mining. It is enough to get a special coaxial pipe for these wall-mounted boilers.

Primary and secondary heat exchangers of Navien double-circuit gas boilers are made of stainless steel. Their service life is 6 times longer than that of similar copper ones. They are less susceptible to corrosion even from hard water. Some may worry that the choice of such material in the production of Navien boilers will reduce their performance. But this is offset by an intelligent boost system.

It is important to know! Representatives of double-circuit boilers Deluxe Coaxial received the highest performance up to 30 kW. If this is not enough, then you need to look towards the Ace TURBO Korea subsection. They have slightly modified the system of work with the supply and removal of atmospheric air, but they will allow heating the area from 350 to 400 m2.

Boilers with increased efficiency «Navien» NCN

How do you like the proposal to reduce heating costs by 30%? This became possible with Navien NCN double-circuit boilers. They use a unique technology that allows you to use the available resources more efficiently. This line combines the advantages of the previous three. There are all systems of protection and control. Additionally, the boiler has a large backlit display that shows the current status. But the whole point is to increase the efficiency up to 108%. How was this achieved?

There are several factors that contribute to this. In a double-circuit boiler, there is no separate supply of first gas, and then air, which is required for its combustion. There is a pre-mixing chamber in front of the burner in the Navien double-circuit boiler, so the substances enter there. Further, the mixture is transferred and ignited through the turbocharging unit of the Navien wall-mounted boiler. But the gases exhausted in a double-circuit boiler are not emitted. They contain a large amount of steam, which is easy to reuse. It enters the condensation unit.

The latter is another heat exchanger, to which a return current is supplied from the common system. Water, passing through this component of a double-circuit boiler, partially raises its temperature. Therefore, it enters the main burner of a wall-mounted dual-circuit appliance with a higher temperature, which means that it needs less energy to bring it to the state set on the control panel. Thus, savings are achieved in the double-circuit products of this line.

Important! Navien NCN boilers have another nice bonus. These double-circuit wall-mounted boilers are able to adjust the operating parameters depending on the weather. Those. if the temperature outside has dropped by another 10º, then you will not need to go and turn the thermostat up to a higher value, everything in the boiler happens automatically. To do this, you just need to mount an additional sensor, which is installed on the street.

Instead of a conclusion

Now you have complete information about Navien gas wall-mounted boilers, so you can certainly make the right choice. The issue of assembling and installing a heating system is up to everyone to decide for themselves. Some people can do most of the work on their own. You can also independently prepare a site for a double-circuit wall-mounted boiler. But its connection is made only by specialists who can correctly put the double-circuit unit into operation and sign all documents. Do not save on quality, and as a result, on your health, choosing low-quality double-circuit boilers. You won't be able to get it back for the rest of the money.
