Wall-mounted gas heating boilers Navien. Choosing double-circuit gas boilers Navien Boilers with increased efficiency "Navien" NCN

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'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.

Korean wall-mounted gas boilers Navien are popular in the Russian Federation for several reasons:

• Gas fuel is the cheapest fuel that the Russian consumer can afford, therefore, heating bills will not be astronomical.
• The most important factor in the continuing popularity of Navien wall-mounted gas boilers is their democratic price. Having similar quality of German brands, Korean models are 30% cheaper!
• Gas is the most environmentally friendly fuel at the present time (electricity in its pure form is much more expensive)! The air near a private house in which a gas boiler is installed is much cleaner than the air into which waste from the operation of diesel or solid fuel heating boilers goes.
• ease of use. The boiler, located on the wall, does not interfere with moving around the room, no need to bend down.

Available models of Navien boilers:

• are distinguished by their maximum power, from 13 kW to 40.5,
• the combustion chamber of the boilers is closed,
• commercially available models of boilers are double-circuit, they have a built-in heat exchanger (metal - stainless steel, blocking corrosion processes), boiling is achieved in a short period of time, up to 85 degrees. The service life of the heat exchanger is very high.
• The SMPS chip protects the boiler against power surges (+/- 32%).
• Navien wall-mounted gas boilers are not dangerous to reduce the temperature in the room!

Navien is a large South Korean corporation that produces versatile, high-quality and reliable gas boilers. Navien devices are distinguished by their trouble-free operation, practicality and functionality. These devices have an open or closed combustion chamber, their functional part is durable. At the same time, their cost is lower when compared with European counterparts.

Navien presents a versatile water heating system

Navien Ace gas boilers are not afraid of low gas and water pressure, they are not afraid of power surges. The operation of Navien gas boilers is characterized by a long period of operation and economical gas consumption. All Navien gas devices comply with the standards and norms of the Russian Federation and have the appropriate certificates.

Frost protection system stability

If the room temperature drops, then automatic protection system is triggered from freezing. When the temperature of the heating water falls below 10 degrees Celsius, the circulation pump is automatically started, as a result of which the constant circulation of the coolant in the heating system is ensured. If the temperature of the heating water drops to 6 degrees Celsius, the burner automatically turns on and the coolant warms up to 21 degrees Celsius.

Operational safety with frequent voltage drops in the network

According to the instructions, the voltage can fluctuate within ± 30 percent, due to the operation of the Switched - Mode Power Supply (SMPS) protection chip on the microprocessor. Wherein boiler operation does not stop which prolongs its service life and prevents breakdowns.

Operating conditions for heating and hot water:

• subject to low inlet pressure in the gas pipeline system - stable and safe operation of the Navien Ace gas boiler is possible at a gas pressure of four mbar (40 millimeters of water column);
• subject to low incoming water pressure in the water supply system - stable operation of the Navien Ace gas boiler is possible provided that the incoming water pressure drops to a value of 0.3 bar, which allows the use of this gas device in homes, where there is a weak pressure of water in the water supply system, including where there are frequent pressure drops in the water supply system.

Rational Design

Navien gas boilers are small in size and light in weight, they are convenient to transport, they are easy to install and there is the possibility of rational use of space. For ease of installation, the connecting pipes are located on both sides of the device, which greatly simplifies the piping and installation of the Navien Ace gas boiler.

Fuel preheating (KR series)

At low temperatures, the viscosity of the fuel increases, resulting in the effect of waxing, which significantly impairs the flammability of diesel fuel and the operation of the Navien gas boiler becomes unstable. This feature of operation is relevant for regions with a harsh climate, therefore, arctic and winter diesel fuel has been created for these conditions.

Gas devices Navien work on any Russian-made diesel fuel However, the cost of winter or arctic diesel fuel is much higher than summer fuel, and the use of summer fuel is impossible at low temperatures without preheating it.

The heating element, which is built into the burner of the Navien gas unit, before supplying fuel to the nozzle, preheats it, resulting in high-quality fuel atomization and uninterrupted ignitability. Due to preheating, Navien Ace gas boilers have the possibility of using inexpensive summer diesel fuel which results in significant savings.

Design

1. The heat exchanger is made of stainless steel

Stainless steel is used for the production of the heat exchanger, thanks to which it does not corrode, which significantly extends the life of the Navien Ace boiler.

2. Modern diesel burner

Due to the modern efficient diesel burner, low noise stable operation with minimal fuel consumption is ensured. According to the instructions the burner can work with any diesel fuel, taking into account all types of fuel produced in the Russian Federation.

3. Fuel filter with replaceable cartridges

The fuel supply system is equipped with a filter to remove unwanted impurities, as a result of which the stable operation of the Navien Ace gas boiler is disrupted. Additional replacement cartridges are included with the Navien device.

4. Russified control panel

With the help of a fully Russified remote control panel equipped with a liquid crystal digital display, a Possibility of economical fuel consumption and reduction of heating costs, as well as constant maintenance of a comfortable temperature in the room thanks to the room temperature sensor built into the control panel.

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.
