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's 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.

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 cover 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.

Offered by our stores today is very wide. Choosing the most suitable model in terms of reliability and quality at the lowest price is a very difficult task. Among the manufacturers of such equipment, the South Korean company Navien is not the last. To give the potential buyer the necessary information about what the Navien gas boiler is, and is the purpose of this article.

What is the principle of operation of Navien boilers

The operation of Navien boilers is based on the same principles as those of similar devices from other manufacturers.

Composition and types of boilers

The structure of each such device includes the following main components:

• gas stove;
• gas supply control mechanism;
• heat exchange device.

In the modification, hot water immediately enters the heating system of the house. models incorporate an additional water heating circuit for the hot water supply system at home (DHW). When this circuit is activated, the heating system is suspended.

Exhaust gas removal

Gas combustion chambers in boilers are open (atmospheric) and closed (). In atmospheric models, smoke leaves the room on its own through the chimney. For turbines, exhaust gases are removed by means of a fan forcibly through a pipe through the outer wall of the house.

Important! In rooms where a gas boiler is installed, permanent exhaust ventilation is required. This is especially important for atmospheric models.

Gas-burners

One of the main components of a gas boiler is, of course, a gas burner. As a rule, modern models are equipped with modulating burners. They allow you to modulate the flame, controlling the gas supply, depending on the need to adjust the temperature of the air in the premises or the water in the DHW system. When equipping the device with an automatically controlled modulating burner, the heating system will accurately maintain the set temperature.

Control and protection systems

When there is a power outage, the gas boiler stops working, when electricity appears, it starts automatically.

In the event of a gas supply interruption, the automation will close the solenoid valve, which will block the possibility of fuel entering the device. In such situations, it is only possible to open the gas supply to the boiler manually.

Modern models have the ability to save energy and protect against freezing. The water temperature is controlled by sensors that automatically turn on the heating of the coolant when its temperature drops to the set value.

Most gas devices, including the Navien wall-mounted gas boiler, include self-diagnosis systems. These systems monitor the operation of all nodes and display on the scoreboard, with the help of codes, information about the problems that have arisen.

Specifications from the technical side

In our market, Navien offers double-circuit wall-mounted gas boilers with the following characteristics:

1. Combustion chambers of any type - both open and closed.
2. The power range of the manufactured devices allows you to heat rooms ranging from 30 to 400 square meters. m.
3. Double-circuit modification makes it possible to heat water for the DHW system.
4. Heat exchangers are made of stainless steel.
5. Both liquefied and natural gas can be used to operate boilers.
6. The amount of water produced for the DHW system is determined by the capacity of the device. For example, a 13 kW device produces water in a volume of up to 11 liters per minute, and with a power of 30 kW - about 17.
7. The electronic control unit has the function of protecting the device from power surges.
8. Most models of heating boilers are equipped with a remote control unit with the following features:
   • the unit displays data on the set values ​​of the temperature of heating water, hot water in the DHW system and indoor air;
   • the display shows information about the problems that have arisen in the operation of the nodes;
   • the buttons on the block turn the boiler on and off, set the temperature mode;
   • the built-in air temperature sensor provides information for regulating the gas burner.

The delivery set for each Nevien gas boiler includes an instruction manual that describes in detail the rules for working with the control unit. There are also more detailed technical characteristics of the device.

Mounting Features

Before buying a gas boiler, you must:

1. Prepare a place for installation. Atmospheric apparatus requires a separate room, at least 2x2 m in size, with exhaust ventilation.
2. The device must be powered by a stabilizer connected to a circuit breaker or a socket that has an emergency shutdown capability.
3. The boiler body must be grounded, so you need to bring a ground wire to the installation site.
4. The wall where the device will hang, if it is flammable, must be sheathed with non-combustible material.

After purchasing the boiler, it is not an easy task to connect it. The factory instruction manual recommends that a specialist from an authorized service center be involved for this.

But if you have the skills to work with pipes and taps, you can try to hang it on the wall and connect the device yourself. The factory manual says it all in detail.

But do not forget that in any case, you will need to call a gas service specialist to conclude a service contract and obtain a special permit for the operation of gas equipment.

Important! Unauthorized connection of gas to the boiler threatens with penalties and even criminal liability.
