Advantages and disadvantages of Navien gas systems

Navien gas boilers have a number of advantages, namely:

• anti-freeze protection device. When the room temperature drops, the system automatically activates an anti-freeze protection mechanism. If the water temperature drops to 10 degrees or below, The circulation pump is automatically activated, which ensures uninterrupted circulation of the coolant in the heating device. If the water temperature drops below 5 degrees, the burner automatically starts working and the coolant warms up to 22 degrees;
• control of the turbocharging system. The turbocharging fan, which is located in Navien Ice Turbo boilers under the combustion chamber, changes the speed of movement according to the counter. It is driven by an APS air pressure mechanism. Thus, air enters the combustion chamber of the system in an amount proportional to the amount of incoming gas. Only such a device for operating the Navien Ice Turbo system with a fan installed under the combustion chamber and the use of the APS mechanism allows for total combustion of gas and minimal heat loss;
• heat exchanger from of stainless steel. Compared to copper, it has high resistance to the appearance of rust and corrosion. And this greatly extends the service life. Although rust resistant, the stainless steel heat exchanger not widely used in boilers, since the heat conductivity is much less than that of a copper heat exchanger. And only in Navien Ice Turbo boilers can a modulated turbocharging system be used to increase the efficiency of the system;
• durable and safe operation of the system in the event of constant failures. The SMPS mechanism installed in the microprocessor protects the system from power failures. Only the Navien boiler works without significant differences. That's why The service life of the Navien system is much longer than other devices;
• amazing ability to use heating and hot water at low pressure;
• the device works great at low water pressure;
• amazing heating technology.

A portable system control distance with a built-in temperature mechanism helps not only save on gas consumption, but also significantly reduce heating costs. Therefore, your home will always have the optimal temperature.

The disadvantages of Navien gas boilers include a constant connection to the network and, despite the protection, the high sensitivity of the sensors to voltage failures. To solve this problem, different stabilizers and batteries are used.

Model ATMO

Navien ATMO gas boilers have a system for removing generated vapors through a simple chimney. This the design is adapted to work in extreme conditions with strong changes in the voltage and pressure of the gas pipeline.

NSN model

This is the most modern Navien gas boiler, which has high performance using steam temperatures. The heated condensate is collected in a heat exchanger, which heats the water flow. Thus, the costs of sources and energy carriers for heating the heat and water exchanger are reduced.

How to install a wall-mounted boiler?

So, you purchased a gas boiler, installed a gas line, installed the heating system, and now all that remains is to assemble everything into one system. Connection of any gas boiler is not a very easy task. And it’s not even that it’s like this the system is a high-tech device, the problem is a little different - each device has its own connection method. Therefore, the installation of the boiler must be carried out by qualified specialists.

Before installing the boiler, if it does not have the necessary equipment, you must purchase:

• temperature emergency mechanism;
• power device;
• thermometer;
• pressure mechanism;
• fuse.

Usually all boilers are equipped with this configuration.

When installing heating systems with an open combustion chamber, you need to have a separate room. Its area should be 4 m2 or more, and the ceiling height should be 2.5 m. There should also be a ventilation system. When installing heating systems with a closed combustion chamber, such requirements do not apply. If you are installing the system, need to have an outlet with automatic sensor emergency shutdown. It is important to connect the stabilizer. The boiler is grounded. If the wall on which the boiler is installed is not resistant to fire, then it needs to be sheathed with protective material. After getting holes between the pipe and the wall, you need to seal them cement mortar. Before connecting the thermoblock, check that there is no debris in the cracks.

Connecting a heating system is a complex process that must be performed by specialists. If you want to buy a Navien gas boiler, then everyone will be happy with its low cost, and they will also be pleasantly surprised by the free installation.

Gas wall-mounted boiler NAVIEN

When a consumer is faced with the question of choosing a gas boiler for heating, he must take into account a large number of criteria ensuring its effective and economical operation. In this regard, domestic and foreign units should be divided. Unfortunately, not all “foreigners” can withstand the difficult Russian operating conditions - low quality coolant, gas and water pressure differences, periodic power outages. True, many foreign analogues today have already been adapted to Russian conditions. For example, the famous South Korean model line “ Navien Ace» with instructions, which stipulate that these boilers can be used in Russia.

The Navien Ace brand is wall option double-circuit boiler. This model refers to Navien equipment with an open combustion chamber and natural removal of combustion products. What is included in the boiler design?

Boiler equipment

The design of the unit includes:

• Two heat exchangers are made of stainless steel, which guarantees their long and reliable operation.
• Remote display of the control unit, which is completely Russified. For the Russian consumer this is a very important condition.
• Built-in circulation pump.
• Expansion tank.
• Safety valve.
• Air vent operating in automatic mode.
• A bypass valve, which is also adjusted automatically.
• Traction sensor.
• Electric current stabilizer.
• Remote control with remote control, which is convenient in terms of maintenance.

The South Korean boiler navien ace is fully equipped with Japanese automation. In this case, the manufacturer provides a warranty period of 2 years. This is a fairly compact device with excellent technical characteristics. The operating instructions for Navien boilers make it easy to understand all the intricacies of setting up the device, modes and temperature ranges.

Classification

Navien Ace gas boilers are divided into two categories:

1. Ace ATMO.
2. Ace TURBO.

The first unit is a simple and traditional boiler with an open combustion chamber, which uses atmospheric exhaust of combustion products. The second is more advanced and has a turbocharged burner. This allows you to efficiently supply gas and burn it when the supply is unstable, which is associated with pressure surges. In addition, the second option is equipped with a special SMPS control system, which is based on highly sensitive chips. They are responsible for monitoring and regulating gas combustion processes. In all other respects, both options are no different from each other.

Both models can be classified as universal technology. Adapted to difficult operating conditions, they are considered one of the most economical heating devices, which are present at today Russian market. An important component of the design is the remote control. This is very convenient when you can set modes and indicators from a distance, quickly making adjustments.

But what’s surprising is that Navien gas boilers can operate not only in automatic mode, but also in manual mode. This is especially convenient when the temperature outside the window changes sharply. Manual installation allows you to more accurately set parameters and indicators, which eliminates the smallest errors during the operation of heating equipment.

Navien ace gas boilers can be called universal units. They operate on natural gas or liquefied bottled gas. To switch from one type of gas to another, you only need to change the burner. No other changes are required.

What to pay attention to during installation?

Since instructions are included with the equipment, there are no problems with installing and connecting the device. Doing it yourself is not a problem. Even a non-professional can understand the instructions. Moreover, it is written in Russian.

The only thing that experts ask you to pay attention to is the method of removal carbon monoxide. They can be discharged through a regular atmospheric chimney connected to the smoke exhaust system of the house or installed as a separate structure. But if you are not satisfied with any option, you can make a coaxial chimney. Its installation is several times simpler. But keep in mind that coaxial structures are used only when the heated area of ​​the house does not exceed 110 m². They can be installed with boilers whose power does not exceed 11 kW.

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

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

Available Navien boiler models:

• distinguished by their maximum power, from 13 kW to 40.5,
• The combustion chamber of boilers is closed,
• The boiler models available for sale 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 long.
• The SMPS chip protects the boiler from voltage surges (+/- 32%).
• Navien wall-mounted gas boilers are not at risk of a drop in room temperature!

It is common knowledge that South Korea- this is a country high technology, supplying the widest range of modern household appliances all over the world, including in states former USSR. And recently, this list has been supplemented with heating equipment running on natural gas. We present to your attention a product from a well-known Asian brand - the Korean gas boiler Navien, which has been sold in the Russian Federation for several years and has managed to gain a certain positive reputation.

Model range of wall-mounted boilers Navien

It should be noted that the first reviews from Russian users about this product were not too enthusiastic. There are objective reasons for this, one of them is frequent leaks of connections, which was eliminated by replacing an expensive set of gaskets. Another trouble was that the Navien Ace boiler offered at that time bothered users with late start-up of the burner, when the coolant in the batteries had time to cool down considerably.

The company has clearly worked on its mistakes, since there are much fewer negative reviews, and the number of supporters of the South Korean manufacturer has increased significantly, primarily due to the reasonable price of decent quality products. Currently, 3 types of suspended gas heat generators are offered under the Navien brand:

• atmospheric;
• turbocharged;
• condensation

The atmospheric series of units with an open combustion chamber is represented by the Navien Atmo brand boiler, which replaced the not very successful Ace model. The heat generator is adapted to difficult operating conditions, which is reflected in the low operating pressure of gas (from 8 mbar) and water in centralized network(from 0.6 Bar). The series includes 4 boilers with a capacity of 13, 16, 20 and 24 kW, equipped copper heat exchanger for heating and separate stainless steel - for heating water for domestic hot water needs.

Note. Only Navien double-circuit boilers, both wall-mounted and floor-mounted, are supplied to Russia and the CIS countries. In addition, all Navien units are equipped with modulating burners, built-in expansion tank And circulation pump, as well as an electric ignition system.

The unit is controlled automatically using a remote control. In addition to the minimum set protective automation The boiler has an additional system that prevents the coolant from freezing. At the same time, the manufacturer prohibits filling the heating system with antifreeze; the heat generator is not suitable for this. The main technical characteristics of the Atmo series are as follows:

• water heating temperature in the heating system – 80 °C, operating pressure up to 3 Bar;
• in the DHW circuit the water is heated to 60 °C;
• gas pressure – from 8 to 18 mbar;
• Efficiency – 86%;
• water pressure in the network is from 0.6 to 8 bar.

Turbocharged models

The Navien line of wall-mounted boilers with a closed combustion chamber includes as many as 3 series of units:

• Deluxe – 7 heat generators with power from 13 to 40 kW.
• Prime – 6 products with a power of 13-35 kW;
• Smart TOK – 6 heaters from 13 to 35 kW.

For reference. The hanging Navien Ace Turbo boiler is a thing of the past, and its place is taken by units of the Deluxe and Prime brands.

The difference between forced-air heaters is that air is supplied into the closed combustion chamber forcibly through a fan, its performance is controlled by a controller. The air entering through the coaxial chimney from the street enters the sealed housing, where it is captured by the fan. Thanks to forced injection, all these models have increased efficiency - 92%.

On this fundamental differences turbocharged units from atmospheric ones are running out. Their equipment is equally rich: a wall-mounted gas boiler Navien Deluxe equipped with an expansion tank, pump and additional heat exchanger for hot water. In addition, the device can withstand voltage drops of ±30 V from the nominal value, and also automatically turns on heating when the coolant temperature drops below 6 °C, bringing it to 21 °C.

The Prime series, just like the Deluxe Coaxial brand boiler, is equipped with a closed combustion chamber and other functional elements listed above. The difference is in the additional module of weather-dependent automation, which controls heating depending on conditions environment. The SmartTOK series is even more automated; these boilers can be controlled remotely via the Internet. To do this, you need to have a smartphone and download a special application onto it.

Condensing heat generators

Unlike the modifications discussed earlier, the heat exchanger of the Navien NCN and NCB boiler is made of stainless steel and is designed to remove not only direct, but also latent heat released when gas is burned. Hence the high efficiency of the units; the manufacturer declares it at 98%. The product package is the same as for turbocharged boilers, only the controller has an expanded number of functions, for example, programming the climate in the house for a week in advance. The NCN series consists of 4 products with a thermal power range of 21-40 kW, NCB - of 4 heaters from 24 to 40 kW.

As for the technical characteristics, in condensing heat generators hot water for a heating system it can be heated to 90 °C, and for hot water supply – up to 65 °C. The maximum water pressure in the centralized network has also been increased; the boiler can withstand up to 10 Bar. The air supply is forced; it can be carried out either using a coaxial or a separate chimney. That is, the homeowner can choose whether to take air from the street or from the boiler room.

Navien floor standing boilers

This type of heat generator is positioned by the manufacturer as universal; they can operate on diesel fuel and on natural gas. In essence, Korean floor-mounted gas boilers are just as well equipped with automation as their wall-mounted “brothers”. The difference is in the installation method and the maximum power of some models. The line includes 4 series:

• LST, 8 products from 13 to 60 kW.
• LFA, 6 heaters from 13 to 40 kW.
• GA, 7 boilers with a capacity of 11-35 kW.
• GST, 5 units from 35 to 60 kW power.

In terms of technical characteristics, they are also similar to suspended ones, the maximum operating temperature is 80 ° C, pressure is 3 Bar. Efficiency indicator - 91%, air supply method - forced injection.

How to turn on a Navien boiler

A peculiarity of South Korean heaters is the presence of remote control panels, which are supplied with all products. The attached operating instructions state that the boiler can be turned on using either remote control, and the buttons on the front panel of the unit. This operation is simple: you need to press the “power” button, its location is shown in the diagram:

After starting, the boiler will independently begin to operate in the mode that was last set on the remote control. To change the settings, you need to take the manual and use it to correctly set all the modes. Before starting a new heat generator, you need to install it, connect it to all engineering networks and fill the heating system with water, focusing on the boiler pressure gauge. The location and purpose of the pipes is shown in the figure:

Navien boiler errors

During startup and operation, various error codes may appear on the device display, indicating a malfunction of the boiler or problems with heating system. The explanation of all codes is given at the end of the instruction manual, but not always in understandable language. We will provide an explanation of common errors.

If the boiler has stopped and error 02 appears on the display, this indicates that the flow sensor in the heating system has activated. The reasons may be:

• the circulation pump has failed or is disconnected from the power supply;
• there is air in the system;
• the filter at the coolant inlet to the boiler is clogged;
• a leak has appeared, but the make-up does not work;
• The sensor itself or its electrical circuit is faulty.

When the unit does not start and error 03 is displayed on the screen, the reason is the flame sensor. It works if it “does not see” the fire, which means there may be problems with the gas supply or its pressure is too low. The cause may also be contamination of the ignition electrodes or the sensor surface. It is possible that the sensor itself may fail or there will be no signal due to an electrical circuit break.

Conclusion

South Korean Navien boilers using natural gas, have become well known to many users, although they appeared relatively recently. In general, their work is characterized positively, but there are also significant shortcomings. For example, a ban on the use of antifreeze in the system, which is very important in harsh winter conditions.
