A story about how I automated an apartment using Node-RED. Part II

Heating boiler Navien: the best of its kind

The Navien boiler is considered the most popular among heating and heating devices. The company presents only high-tech models for installation in all kinds of premises. On sale, everyone will be able to find a device that will serve them well for a very long time - and all this at a fairly attractive price. Wall-mounted solutions are best suited for heating apartments and small private houses.

Korean Navien gas boilers are double-circuit boilers that have an open and closed combustion chamber. They are used for heating and heating water for domestic and technical purposes. The entire automation system and documentation have been translated into Russian, thanks to which everyone can easily study the existing instructions, as well as successfully save on heating costs by continuously maintaining the desired temperature in the premises. Uninterrupted and safe operation of the boiler is possible even in conditions of frequent power outages. If the voltage in the network fluctuates, the SMPS protection system is activated, after which the boiler continues to operate properly. In particular, thanks to this function, these double-circuit boilers have a long service life without breaking down or requiring subsequent repairs.

A little about the company...

NAVIEN is the largest Korean manufacturer of universal heating equipment. It produces mainly gas boilers, chimneys for them, diesel boilers, and other energy-related mechanisms and intended primarily for home use.

Components for Navien boilers and chimneys are manufactured in Korea and Japan. And assembly takes place exclusively at our own Korean factories, under the strictest quality control. The quality meets ISO9001 standards. Thanks to this, Navien has become one of the largest manufacturers and sellers of heating equipment. It carries out up to 85% of its sales in Korea, Japan, as well as in the United States, the Pacific region and Russia.

NAVIEN products are often represented by the following boiler models:

• Condensing boilers - model “NAVIEN NCN”
• NAVIEN wall-mounted gas boilers Ace TURBO (Korea and Coaxial modifications)
• NAVIEN wall-mounted gas boilers Ace ATMO

In addition, each of these types has its own subtypes (in terms of power and other technical characteristics), and for each of them a corresponding set of navien chimneys is produced.

I would also like to note that NAVIEN equipment works without problems in our conditions, it is perfectly adapted to them. The equipment is not afraid of low water and gas pressure, nor sudden changes in voltage in the network. The operation of boilers means high DHW performance, economical fuel consumption and a long service life! The navien boiler and chimney meet all standards and regulations adopted in Russia and Ukraine! This is confirmed by relevant certificates!

Types of wall-mounted boilers

Atmospheric gas boiler NAVIEN ATMO 24-AN

There are three types of wall-mounted heating devices of this class on the domestic market:

• Navien atmospheric (open) boiler;
• turbocharged wall models;
• condensing devices.

Each of these positions requires separate consideration.

Atmospheric gas boilers

Units of this type have an open combustion chamber. Represented by the Navien Atmo model. It is intended for operation in conditions of uneven gas pressure (its differences can reach 8-17 mbar) and the coolant itself - from 0.6 to 8 bar. The power of the offered units varies from 13 to 24 kW. At an operating temperature of 80°C, the coolant heats hot water to 60°C with a production volume of 10 liters per minute. To remove combustion products, they are equipped with standard chimneys.

The heating circuit in atmospheric boilers is made of copper, and the heat exchanger body is made of stainless steel.

Turbocharged units

Turbocharged boiler Navien Deluxe 10 Coaxial

The group of units of the second type (with an isolated combustion chamber) includes models of the following series:

• Prime, represented by boilers with a capacity of about 13-35 kW;
• Deluxe, whose declared power ranges from 13 to 40 kW;
• modern Smart TOK models with an indicator of 13-35 kW.

Portions of air are forced into the isolated combustion chamber - they are pumped through a special fan installed in a coaxial pipe. Thanks to this, units with a Coaxial design have a higher efficiency, sometimes reaching a record figure of 93%. Gas boilers from the Navien Deluxe series are able to withstand significant changes in supply voltage, as they are equipped with a built-in stabilizing device. In addition, they have the option of automatically maintaining the temperature of the media at a level not lower than the “cooling point” (6-9 degrees).

Condensing boilers

Condensing gas boiler Navien NCN 40KN

The third type of Navien gas boilers is represented by samples of equipment from the NCN and NCB series. Due to additional heating of the carrier with the heat of the condensate, their efficiency was increased to 99%. The functionality of these units is even higher than that of turbocharged boilers - the controller built into them allows you to set temperature parameters for a week in advance.

The Navien NCN product series includes four varieties with power from 22 to 40 kW, and NCB has the same number of products with ratings of 24-40 kW. The water in them is heated to 65°C, and the coolant circulating through the pipes is heated to 90°C. These units are able to withstand media pressure up to 10 Bar.

The air supply in equipment of this class is organized through a coaxial or conventional chimney.

Double-circuit wall-mounted gas boiler Navien, reviews, connection

For many years, the Navien gas boiler has been perceived by professionals as the most functional solution to all problems associated with hot water supply and heating of residential and other premises. In today's private housing, these devices can certainly be called the only way out of the situation, so in apartment buildings these devices are very often installed as an additional option.

gas boiler Navien Ace

1. During operation of such a device, there is no need to allocate an individual boiler room for it. In other words, this device can be placed directly in the kitchen without fear.
2. The funds you spend installing a wall-mounted Navien Ace gas boiler will fully pay off within the next year of vigorous use of such devices, since they provide extremely favorable fuel consumption.
3. Modern heat generators are equipped with a multi-stage security system that makes it possible to protect them from overheating in the event of breakdowns in the operation of the water pump. In this case, it is necessary to highlight the fact that the device turns off the burner on its own, for example, if the gas supply is completely interrupted.
4. All the newest models of gas-fired boilers are equipped with a special external thermal converter and the latest electronic filling, which ensures that the heat level is constantly maintained at the desired level and makes it possible to adjust the heat supply intensity in an acceptable manner.

Thanks to this, Navien gas heating boilers have become so popular today. You can read reviews about these devices on a wide variety of resources, but you, of course, need to make sure that they are almost always positive.

Almost every floor-standing Navien gas boiler is equipped with a separate gas supply system, thanks to which it is supplied both for heating the room and for heating water, thanks to which the hot water supply system can be used without any damage to the efficiency of the heat supply.

In the automatic circuit control system with which Navien gas boilers are equipped, technical properties have priority in the direction of hot water supply. Likewise, as soon as the client opens the water supply tap, the heating circuit is completely turned off, and the burner starts working only to support the hot water supply so that the water can be heated in flow mode.

If you need to achieve a continuous supply of hot water in large quantities, then in such a case it is most optimal to use a special integrated electric water heater in combination with a double-circuit heater, since by using it you can eliminate the prolonged shutdown of the heating circuit, which will make it possible to always maintain the desired temperature regime at indoors of your living space.

In addition, it should be noted that these specialized types of boilers provide a constant supply of hot water of 70 liters, and their storage tanks have special protection against scale and are able to work well even with minimal water pressure.

If you find that the consumption of hot water is too excessive, then in such a case it will be possible to additionally connect a special indirect electric water heater to the double-circuit heater, the volume of which can be up to 1000 liters. Very often, the instructions for connecting an electric storage water heater contain instructions for operating a Navien gas water heater.

Specifications of Navien boilers

At the same time, it is necessary to note the additional good quality that Korean Navien gas boilers have. Reviews from consumers often indicate that wall-mounted boilers are small in size and have sufficient throughput for many apartments, making it simply impractical to install floor-standing equipment in such rooms.

This will have almost no effect on the productivity of such devices, especially since almost all of today’s manufacturers are trying to reduce the total weight of the heat generators used in their own devices in order to guarantee the versatility of their own equipment and the ability to install it even in small rooms.

If we are talking about what are the important advantages of gas-fired boilers over solid fuel ones, it is necessary to note, at a minimum, their productivity and economy. It doesn’t matter whether we are talking about the use of liquefied or gas - in any case, the operation of the Navien gas water heater will be much more economical and will pay for itself after just a few years of vigorous operation.

How boilers work

The technical structure of wall-mounted devices includes the following elements:

• burner;
• frame;
• a water pump, which is designed to move water in a closed circuit;
• expansion pump;
• pipe coil.

The connection diagram for a wall-mounted two-stage gas boiler Navien is considered very simple: to fully install the boiler, it is enough to simply connect the pipes to the mixers, and also bring them to the entrance to the heating system.

All modern boilers differ from each other depending on what kind of burner they actually use. If we are talking about boilers with an open burner, then these devices require the forced supply of a special chimney, which operates on the principle of natural draft. In this case, oxygen for the burner is taken from the room in which the boiler is installed, so it will be necessary, first of all, to support a continuous flow of clean air.

Most often, it happens when a person does not follow the operating rules when using a Navien gas boiler, the message “Error 03” appears on the indicator, but this problem is very often quickly solved by professional craftsmen.

The design of the closed burner takes into account the use of a special coaxial type chimney, through which oxygen is supplied and various combustion products are removed. Such systems are activated by forced draft through a fan, which is built into the boiler design from the very beginning, and the pipe is vented outside through the wall.

When choosing a suitable boiler, you will need, first of all, to correctly calculate the boiler power, which is measured in kW and is determined by the area of ​​​​the expected heat supply of the boiler. At the same time, before installing the Navien gas water heater, make sure that when heating every 10 m2 of living space, the boiler spends approximately 3 kW of power.

It would be most advisable if the heat generator had several outputs and inputs at once, especially if you decided to purchase this device in order to guarantee heat supply and hot water supply in a cottage outside the city. By using several outputs, you will be able to ensure the possibility of installing additional components and devices, among which, for example, it is necessary to highlight heat exchangers for swimming pools, indirect electric water heaters, hydraulic floors and much more.

When deciding on ignition, experts advise paying attention only to electronic ignition, since in this case you will not have any need to approach the boiler to activate it - you can simply activate the automatic system or turn on the device from a distance.

In addition, in piezo ignition there is no regularly burning ignition device, which can cause breakdowns of the Navien gas water heater and affects the overall safety of using such units.

To save yourself from surges, it is most advisable to ensure that a special electrical voltage stabilizer is provided in the boiler from the very beginning, which will enable you to repair boilers running on Navien gas less often.

It should be noted that it is most optimal to use boilers with additional operational reliability, since any errors in the interaction with gas lead to poor results.

In particular, several important functions should be noted, the action of which is aimed at preventing danger.

1. Flame meter. With the help of such a device, the fire is extinguished, and if this happens, the automation is activated, which completely turns off the gas supply.
2. Blocking thermostat. If the water overheats, this situation is detected by the sensor, and it sends a signal to automatically turn off the gas supply.
3. A shutdown device that is triggered when the coolant level is insufficient.
4. Blockers that are activated when the gas supply is completely stopped, as well as when the water supply is turned off and voltage changes occur.

All these types of systems are designed to guarantee the most effective protection of the residential complex from the occurrence of a variety of explosions or fires, so if the above indicators are present, the gas boiler you install will, in any case, maintain trouble-free operation for decades, successfully heating your home.

Gas boiler care

To avoid problems with the boiler, you should master the basic techniques for caring for it. In order not to lead the situation to the need for repairs, the user must adhere to the following operating rules:

• keep the boiler clean, avoiding accumulation of large amounts of dust;
• periodically check the voltage in the network;
• control the coolant pressure and prevent it from falling below the limit level.

To ensure reliable protection of the purchased equipment, careful familiarization with all typical errors and the ability to eliminate their consequences will help.

My works of 2021.

How I set up the Navien boiler, pump and blower run-out

First, the question is, why regulate the run-out of the pump and blower, well, probably so that they work less and wear out less, as I noticed, while with the experience of the boiler in winter mode, the blower spins after stopping the boiler for another 1 minute, at this time there is cold air from the street, no longer heating up in the coaxial chimney, it intensively cools the boiler heat exchanger, which is generally detrimental to its health, and unnecessary heat loss into the atmosphere, i.e. it is possible, without damage to the boiler, to reduce the fan run-out time, about this procedure, and at the same time, about the procedure for reducing the pump run-out (relevant in summer mode, when the boiler is turned on only to heat hot water, and turns off again), in more detail and in order

If anything, I have an engineering menu file for download from the Koreans with a crooked translation, but in it everything that I could tell on the pages, well, maybe a little more, there is just a mention that if the boiler remote control fails, then by shorting the remote control wires from the boiler itself, you can turn it on, but it will heat the heating system up to 80 degrees, but at least we won’t freeze until we buy a new remote control, or the repair team arrives with a spare remote control!

Review of Navien Ace Atmo -13 - a luxurious gas boiler for an apartment

In 2010, the opportunity arose to make repairs and change the gas equipment in the apartment. It’s lucky that the godfather is engaged in the renovation and construction of apartments. Including installation of gas heating. He said his customers who bought Navien models had no problems. The manufacturer is a Korean company, the price is affordable for me, the quality and functionality are good.

The man said, and the woman decided)) Now our apartment is heated by this “handsome guy”:

I started by studying the characteristics, reviews and prices of boilers on the Internet. The requirements were the following:

• Decent manufacturer
• Quality confirmed by real reviews
• Dual-circuit system (heating and hot water availability)
• Economical gas consumption with high energy output
• Easy to use (so even a lady can figure it out)
• Availability of inexpensive spare parts
• Compact dimensions (I wanted to install it in a kitchen cabinet)
• Long service life
• Hassle-free service
• I can afford the price

There are many characteristics, but they are all quite objective for a poor, independent woman.

The Navien boiler suited my parameters according to its parameters and the price was quite affordable at that time - 23,500 rubles, but the reviews varied greatly. About three quarters of them are positive. The rest of the writers complained that the boilers break down almost immediately, always leak, and burn out.

One lady stated that her relative, who installed such boilers, had to constantly repair them due to leaks.

My godfather very picturesquely explained where that “relative” came from: boilers need to be installed and operated correctly. The biggest danger for them is airing, condensation, contamination of burners and hard, not very clean water in the pipes. Problems will appear if the heating system is assembled incorrectly, the boiler is not connected correctly, or both are operated incorrectly.

(The photo shows the connection of our boiler to the heating system, everything is assembled correctly)

Don’t be lazy and spare the money and install an expansion tank in the heating system and a water filter in the water supply. My godfather practically ate the money from me for all these additions.

It was under his responsibility that I bought myself a gas boiler Navien Ace Atmo - 13A. Actually, for those who write such negative reviews, I want to say: flammable heating equipment is not a toy and requires compliance with the instructions during installation, installation and use!

• Advantages: Price, economical consumption, small dimensions, functionality, Korean quality and reliability. The device is designed not only for the conditions of the Russian winter, but also for the possibility of a power outage and low gas and water pressure.
• Disadvantages: Dependence on the electrical network.

And Navien Ace Atmo - 13A is an excellent double-circuit boiler. Power up to 13 kW with an efficiency of 86%. It consumes 80 W/h of electricity and connects to a standard power outlet. The dimensions of all models are the same - 720x430x340 mm. At first I was going to hide it in the kitchen cabinet, and then, when I bought a model with such an original design, I didn’t. There is a surge protection fuse.

The boiler is designed to heat an area of ​​up to 130 sq. m. I have 58 square meters and at -30 0C outside we wear shorts in the apartment. An easy-to-use remote electronic panel on a long wire, which has a built-in ambient temperature sensor.

You can set the desired heat level for the batteries from 40 to 80 0C - this is convenient if the boiler and sensor are not located in a residential area. In this case, there is also a function to protect the boiler from freezing - my friends have a more powerful Navien model installed on the terrace of their house. The boiler can start if the temperature in the apartment drops below the set temperature, as I do.

The heating can be turned off for the summer and only hot water can be used. Heating is set in the range from 30 to 60 degrees. A stream with a given temperature flows from the tap within a minute. In the heat of summer, when the pressure in the pipes is very low, we always had hot water.

Gas consumption is economical - from 0.98 to 1.33 cubic meters. m per hour. During the cold season, my gas bills are about 600–700 rubles and on average 200 rubles in the summer. This despite the fact that I also use a gas hob.

For me, there is only one drawback to the boiler: if there is no electricity, it does not work. In principle, all boilers have built-in pumps and electronic control panels. So it’s difficult to consider this a disadvantage. And our lights are practically never turned off.

In general, Navien Ace Atmo -13A is good, solid equipment. And it’s a shame that they criticize her.

Basic malfunctions and their solutions

Any faults that occur are shown on the display as a numeric code. Each of them corresponds to a specific error, i.e. a signal from a specific sensor about the failure of the corresponding node.

Let's look at them in more detail:

• E 01. Exceeding the heating temperature. Indicates a failure of the circulation pump or a clogged coolant filter.
• E 02. Exhaust circulation error. Possibility of coolant leaks.
• E 03. Gas does not burn. Check whether the gas supply valve is open.
• E 04. Parasitic flame. The sensor may spark and perceive it as an open fire.
• E 05, E06. Exhaust temperature sensor short circuit. Occurs due to the appearance of condensation on the board with the sensor.
• E 07. DHW temperature sensor failure. Check sensor contact.
• E 08. Short circuit of the DHW heating sensor. Replacing the sensor.
• E 09. Fan failure. Replace the fan.
• E 10. Problems in the smoke removal system. The chimney may become clogged or the outlet channel may become icy.

There may be additional codes that must be carefully reviewed in the user manual.

Error codes and how to fix them

Let's look at the most common mistakes in the video. For this, many thanks to the Repair-31 channel.

Error 10

Automated self-diagnosis complexes, in combination with boiler protection systems, prevent the most serious breakdowns almost at the initial stage. When detecting a particular malfunction, the program turns off the boiler and displays a code on the LCD display.

The most common failures of Navien boilers:

E01 indicates overheating of the coolant in the boiler unit. For atmospheric ATMO models, the electric pump does not function, since in these modifications there is no heating medium flow sensor, so the pump will need to be replaced. You must first check the operation of the heating system for airiness and the presence of contamination in the filter installed in front of the boiler unit. E02 indicates a network water circulation error. Error 02 on the Navien boiler is eliminated by checking the circuit for leaks. The pressure in the network is set from 1 to 2 bar; if necessary, the network must be recharged. Check the operation of the shut-off valves and three-way valve; they may be blocked. Check the operation of the flow sensor. If after these procedures the problem is not resolved, the board must be replaced. E03 indicates the absence of an electrical signal due to the presence of a flame in the firebox or a break in the primary sensor line. In the Navien boiler, error 03 is checked in the inspection window for the actual presence of a torch. If it is not there, check the electrical resistance of the coils on the gas line cutoff. Monitor the presence of a spark on the electronic ignition system and the gas pressure in front of the boiler unit. The torch may come off due to the large volume of air supplied by the fan. E04, false alarm due to flame in the burner. Error 04 on the Navien boiler is possible due to a leak in the gas shut-off valve or a spark from the ignition system is supplied to the flame sensor. The electrode unit will need to be replaced. If the problem persists after this, the board will need to be replaced. You will first need to check the grounding in the boiler with a resistance limit of at least 4 ohms. E05, error 05 - there is a break in the return temperature sensor line or its temperature is less than 14 C. Before carrying out repairs, check the humidity at the sensor connection. E06, error 06 - short circuit in the return temperature sensor line or its temperature is above 120 C. Check the electrical resistance of the sensor: 20 C - 10.0 kOhm, and 50 C - 3.6 kOhm. If the value is not normal, the sensor will need to be replaced. E07, violation in the DHW sensor line. A similar sensor check as above is needed. E08, short circuit in the DHW sensor line. A similar sensor check as above is needed. E09, error 09 - fan malfunction. You will need to check the incoming voltage on the board in the inclusion zones of the black and red conductors. If the voltage parameters are normal, but the rotation speed is low, less than 420 rpm, it is necessary to replace the electric fan, since ignition will not occur. If the electric fan speed is 2100 rpm. and the failure is not resolved, most likely there is a short circuit in the triac line; the electronic board must be replaced. E010, error 10 confirms a failure in the smoke exhaust circuit due to clogged smoke exhaust channels

It is necessary to inspect and clean the chimney, and pay attention to the air intake grille to see if it is clogged with foreign substances.

Features of the Navien gas boiler

Navien produces devices of various capacities designed to provide heating for gas-fired homes. However, the technical features of the models allow them to be converted to an autonomous gas supply, that is, connected to cylinders.

A wide range of models allows you to choose a model to suit any needs and capabilities.

• wall and floor;
• single-circuit and with hot water supply;
• with atmospheric and closed combustion chamber;
• with different heating outlet sizes (three options: 20, 25, 32);
• with different chimney diameters;
• and of course, the models differ in power and size.

The manufacturer did not neglect the design.

The devices have an elegant appearance and fit well into a kitchen or any other interior.

Security systems supplied with Navien boilers:

• Modulated turbocharging.
• Protection against coolant freezing.
• A special chip (SMPS) protects against 30% power surges.
• A control panel with a temperature sensor that allows you to maintain t constant and adjust the operation of the boiler to special circumstances.

Modulated turbocharging. The system is based on the interaction of a fan supplying combustion air and a pressure sensor (APS).

The fan rotation intensity changes in proportion to how much gas is supplied at the moment. This allows you to use resources economically and increase efficiency without wasting fuel.

Owners take the choice of equipment such as a gas boiler seriously. Read information about the Baxi gas boiler, the manufacturer, as well as the unit models on our website.

Read about the purpose of an air valve for heating here. Operating principle and design features.

And in this topic https://microklimat.pro/sistemy-otopleniya/elektricheskoe-dachnogo-doma.html we will consider options for electric heating of a private house. Types of electric heaters and electric boilers.

Design and main elements of the boiler

It is important to know your boiler in order to carry out basic maintenance. Although the model may vary from model to model, the main elements can be found in the case:

• combustion chamber;
• heat exchanger;
• expansion tank;
• gas burner;
• circulation pump;
• Control block.

Particular attention should be paid to the design of the lower part of the case, since this is where the inputs and outputs of the circuits are connected, and other important parts are located.

Navien boiler diagram

Closer to the wall there are 4 connecting pipes:

1. Feed input.
2. Return inlet (with safety valve).
3. Hot water outlet.
4. Cold water.

Next is a small gas supply pipe.

In front of the return inlet there is a hot water filter, and even closer there is a drain plug.

In front of the DHW outlet there is a make-up tap, through which the system is filled with water.

Range

The assortment of the South Korean company Navien is constantly expanding, which allows customers to purchase gas boilers that are optimally suited in all respects.

Therefore, it is impossible to talk about all representatives of the model range. Instead, we will look at Navien equipment, which can be divided into three broad categories.

1. Wall models. Wall-mounted boilers have a double heat exchanger and are labeled as Ace, Deluxe. Deluxe are dual-circuit models that have a wide power range from 13 to 40 kW. All Deluxe series boilers are turbocharged. Turbocharged Deluxe equipment can have a coaxial or separate chimney. In addition to Deluxe, the Ace series of wall models is in great demand. The Ace series is divided into Turbo and Atmo. The difference between them is that Turbos are fully adapted for operation in conditions of non-steel gas and electricity supply to the boiler. An additional advantage of Ace Turbo is frost protection and burner turbocharging. If we talk about Atmo, then this is a classic gas boiler that perfectly provides heating for a private home. Atmo has all the strengths of the Turbo, except for the turbocharging of the burner.
2. Floor-standing boilers from Navien. If wall-mounted models do not suit you for one reason or another, floor-standing models have earned excellent reviews. They are used for heating and hot water supply of private houses. The distinctive features of floor-standing models of Navien boilers include their compact size, ease of operation and convenient installation. Each boiler comes with detailed instructions, according to which even a novice in such matters can carry out the installation. Wall-mounted models are somewhat easier to install, although there are no problems with them. A double heat exchanger significantly increases the efficiency of heat generation in a gas boiler.
3. Condensation. Deluxe, Ace and other models of the Navien company recently received a serious competitor in the form of South Korean condensing boilers. They are marked NCN. Their distinctive feature is increased power, the range of which is 19.6-37.9 kW. These boilers use fuel efficiently, using less fuel but providing higher quality heating. The efficiency of Navien condensing-type boilers reaches 108 percent. This was made possible by using the heat that is released when steam condenses. This way, consumers save money on gas bills, but heat their own homes more efficiently. The heat exchanger here is slightly different. Its design is unique and is distinguished by the presence of a system for preliminary creation of a combustible mixture. The burners are necessarily modulating, the range of operation of which is amazing.

By choosing boilers from the Navien company from the Deluxe, Ace or other ranges, you are buying quality and reliability. This is one of the few cases where the manufacturer does not demand more just for the brand. The high level of Navien boilers is beyond doubt.

How to turn off heating on a Navien boiler

If there is no need to use the heating boiler for a long time, you need to turn it off for this time. Next we will tell you how to turn off the heating on the Navien boiler.

1. Now it is necessary to de-energize the structure and shut off the gas supply.
2. Since the coolant has been completely removed from the system, it is necessary to close the corresponding valves.
3. You need to open the drain tap and wait until all the water flows out.
4. The tap in the hot water supply system is closed.
5. Open the plug and release all the water from the heating system.

After this, the boiler can not be used for a long time without any problems.

It is important to know how to turn on the Navien boiler for heating. This is done as follows.

When it needs to start, you need to fill the system with water. Then you need to bleed the air. To do this, he is allowed to leave the battery. And then they bleed it from the circulation pump. After this, water is added again. After this, the device can be turned on.

Navien Ace

The advantages of boilers of this brand are increased reliability and economical gas consumption.

These heating devices are able to operate efficiently even when the incoming gas pressure drops to 4 mbar (40 millimeters of mercury) and when the water pressure in the water supply network drops to 0.3 bar.

The procedure for turning off the heating on a Navien boiler is the same as described above.

Navien Deluxe

This is a new model of Navien boilers, it has the following features:

• There is built-in protection against cold weather problems. If the temperature reaches −7 degrees, the gas burner will turn on automatically. If it is -10 outside, then a continuous circulation system is activated, in which the coolant will move through the pipes continuously, preventing freezing.
• The material for creating the heating system at Navien Deluxe is stainless steel, which makes the work better.
• The possibility of trouble-free operation is provided in case of strong differences in electrical voltage, as well as at low coolant pressure in the heating system.

Turning off the heating in this system is no different from the usual procedure described above.

Possible malfunctions and ways to eliminate them

Navien error codes:

• 01 – overheating (check if the pump is working and if the filter is clogged).
• 03 – no gas (check if the tap is open).
• 04 – false flame signal (check the serviceability of the gas valve, replace the electrodes or board).
• 05 – 06 – Short circuit on the temperature sensor or open circuit.
• 09 – problems with the fan.
• 10 – problems with smoke removal (check the operation of the fan, whether the chimney is clogged, whether the fan pipes are connected correctly, gusty wind could also be the cause).
• 013 – Short circuit on the OM flow sensor.

If the boiler does not give any errors, but works much worse, the reason may be a clogged filter or an airy system.

Navien boilers, like any other equipment, require good care and proper handling. Regular checks and service control will help avoid breakdowns.

Installation of an internal electrical network is an important stage in the arrangement of a new building. Electricity in a private house with your own hands - how to do the wiring correctly? Read the advice of professionals.

Eliminating common errors

Let's look at the common errors of Navien boilers and figure out how to fix them.

Error “02” - stop coolant circulation

The filters of the boiler or heating system often become clogged, this leads to the appearance of two unfortunate numbers of fault 02. It is also very likely that the cause of this error is the main heat exchanger clogged with scale. These troubles occur due to the high hardness of the water used to operate the device. The ubiquitous scale affects the most important parts of the device, stopping operation. To resume boiler operation, you must:

• Clean the filters in the boiler itself and the heating system.
• Remove the heat exchanger from the housing.
• Prepare an acid solution to destroy scale on the heat exchanger.
• Place the heat exchanger in a container with an acid solution.
• Wait for the chemistry to do its job.

After simple manipulations, if you have the necessary ingredients and knowledge, you can independently get rid of error “02” of the Navien gas boiler. Monitor the circulation sensor inside the boiler, wash the filters regularly to avoid unpleasant surprises.

Error "03" ignition problems

It says either a simple lack of gas or a broken gas valve. Let's look at the second option. Navien boilers are equipped with the most reliable Japanese gas valves; they are difficult to break when using the boiler perfectly and correctly. But if the mains voltage is ten to twenty volts higher than 220 volts, the coils inside the boiler will turn black and the valve may break completely. To fix this breakdown, you will have to buy a completely new valve and replace the broken part. Extreme care is required with the network voltage. Increased levels can harm more than one boiler.

Error “16” overheating of the main heat exchanger

Occurs when the boiler’s internal thermometer records a temperature of 95 degrees. This Navien boiler error may indicate several breakdowns of the boiler system. Again, the main heat exchanger is clogged with scale due to hard water from the centralized water supply, which causes the device to heat up to a high temperature. Or it could be an insulation problem with the main heat exchanger. The fact is that if you actively use the boiler for five years and do not provide proper care, it is likely that the gaskets, which should not release the heat of the heat exchanger, begin to blow out. Warm air blows directly onto the thermometer - an error occurs. To eliminate error “16” you need to clean the main heat exchanger in an acid solution and restore its insulation. But it is better to prevent this problem by regularly carrying out boiler maintenance; if possible, then using water that is safer for equipment.

Navien mounted boiler: characteristics

was in a warmer zone, we immediately realized that this was not suitable for us, at first there were thoughts of moving the remote control downwards, closer to the floor, but, firstly, this is inconvenient for control, secondly, domestic cats could ruin it, thirdly, the boiler could do not turn off, trying to catch up with the temperature below, when it is already hot in the middle part of the room in height.

The room temperature test did not pass and was not suitable for me, at the same time I remembered the person who connected the gas, who advised that the boiler should not be turned on in this mode.

Time passed, but the cycles did not give me peace, and one day it occurred to me, while regularly observing the boiler, that the hysteresis (delta) in the turn-on-switch-off segment of the gas boiler was probably too small, and I would like the boiler to drive the coolant longer to a higher level. low CO temperature, but it was unclear how to do this, I certainly know how to program, but programming languages ​​for this boiler are inappropriate, and I don’t have equipment to connect to the “brains” of the boiler, and one day, purely by chance, I came across one well-known forum for a person who knows how to do this, and with the help of only one remote control, by entering the engineering menu of the Navien boiler!

This is literally what needs to be done. to change the delta between boiler start-stop.

1. With the Navien boiler remote control turned off, press the + and - buttons for 5 seconds

mode setting

2. The number 8 or 9 or 10 will appear on the remote control display (for me)

3. Again, use the + or - buttons to change the value (this is delta) in the range from 2 to 20 (I set it to 12)

4. We wait 5 seconds, after which the boiler remote control goes out

5. Turn off the boiler by removing the plug from the socket for at least 10 seconds

6. Temperature difference value saved

Having done all this, I immediately realized the difference, the intervals between starts and stops of the boiler increased, although it raised the delta by only 2 degrees!, a useful thing, the engineering menu of the Navien boiler!

How to increase the time between starting and shutting down a gas boiler?

If there is a problem with frequent switching on and off (“clocking”) of a gas boiler, you can change the difference between starting and stopping the unit. This is possible using the Navien engineering menu:

1. Turn off the remote control and press two buttons “+” and “-” at the same time.
2. A number from 2 to 20 appears on the display. Usually 8 or 10.
3. Use the “+” and “-” keys to increase the delta value between start and shutdown.
4. After 5 seconds, the remote control goes out.
5. The boiler is turned off and then turned on again.

Now the gas unit will operate in a new mode.

When cold weather sets in, the house needs to be warmed up. However, heating is a costly procedure. Therefore, the owner is interested in finding opportunities to save money. One option is the ability to turn off the heating when it is not needed. To carry out this procedure correctly, you need to know its features, which are described in more detail in this article.

Pros and cons of Navien gas systems

A gas boiler for heating a private house Navien has a number of undeniable advantages:

• Frost protection.
  When the indoor temperature drops, the system automatically starts the frost protection mode. When the water temperature drops below 10 ºС, the circulation pump is turned on, ensuring constant circulation of the coolant in the heating system. When the temperature drops below 5 ºС, the burner lights up and the coolant warms up to 22 ºС.
• Availability of a turbocharging system. The turbocharging fan in such boilers is located under the combustion chamber and changes its rotation speed according to the counter. It is directed from the APS air pressure mechanism. It turns out that air enters the combustion chamber in a volume proportional to the volume of supplied gas. Only such an Ice Turbo system with an installed fan and APS mechanism makes it possible to ensure complete combustion of gas with minimal heat loss.
• The presence of a stainless steel heat exchanger. Unlike copper, it has high oxidation resistance. This nuance significantly extends the life of Navien wall-mounted gas boilers. However, even taking into account the high resistance of stainless steel to rust, such heat exchangers are used in boilers extremely rarely, since they have a much lower level of thermal conductivity compared to a copper heat exchanger. And only Navien ace Turbo wall-mounted gas boilers have a simulated turbocharging system to increase the efficiency of the entire system.
• Long-term and safe operation of the system in conditions of constant external failures. The SMPS function found in the microprocessor protects the system from damage during power outages. Only Navien boilers manage to function normally under conditions of significant fluctuations. This extends their service life significantly compared to other heating devices.
• The ability to heat the room and heat water in conditions of low pressure in the system.

The automated mobile heating control system, thanks to the presence of built-in temperature sensors, makes it possible to significantly save on gas consumption.

How to turn off heating on a Navien boiler

If there is no need to use the heating boiler for a long time, you need to turn it off for this time. Next we will tell you how to turn off the heating on the Navien boiler.

1. Now it is necessary to de-energize the structure and shut off the gas supply.
2. Since the coolant has been completely removed from the system, it is necessary to close the corresponding valves.
3. You need to open the drain tap and wait until all the water flows out.
4. The tap in the hot water supply system is closed.
5. Open the plug and release all the water from the heating system.

After this, the boiler can not be used for a long time without any problems.

It is important to know how to turn on the Navien boiler for heating. This is done as follows.

When it needs to start, you need to fill the system with water. Then you need to bleed the air. To do this, he is allowed to leave the battery. And then they bleed it from the circulation pump. After this, water is added again. After this, the device can be turned on.

Navien Ace

The advantages of boilers of this brand are increased reliability and economical gas consumption.

These heating devices are able to operate efficiently even when the incoming gas pressure drops to 4 mbar (40 millimeters of mercury) and when the water pressure in the water supply network drops to 0.3 bar.

The procedure for turning off the heating on a Navien boiler is the same as described above.

Navien Deluxe

This is a new model of Navien boilers, it has the following features:

• There is built-in protection against cold weather problems. If the temperature reaches −7 degrees, the gas burner will turn on automatically. If it is -10 outside, then a continuous circulation system is activated, in which the coolant will move through the pipes continuously, preventing freezing.
• The material for creating the heating system at Navien Deluxe is stainless steel, which makes the work better.
• The possibility of trouble-free operation is provided in case of strong differences in electrical voltage, as well as at low coolant pressure in the heating system.

Turning off the heating in this system is no different from the usual procedure described above.

Adviсe

Even the exceptional skill of South Korean manufacturers does not allow 100% to eliminate the occurrence of violations and problems during operation. Poor water heating is mostly due to the filling of the heating system with air pockets. The problem is solved by removing accumulated air or changing the automatic vent. It is also possible that the filter in the heating circuit is dirty.

This situation can be corrected either by adding water or eliminating the leak. Code 3 indicates that gas is not supplied to the burner. It is necessary to check what position the valve is in, whether the fuel in the cylinder has run out, and whether there are any accidents on the line. Judging by the reviews of the owners, South Korean boilers are more compact than many other versions and are characterized by rapid achievement of the set temperature. But it is noted that there are no control elements on the boilers themselves and that occasionally turning on two hot taps on the water supply reveals insufficient heating power.

If the boiler is leaking, in many cases it is water leaking from a drain plug that is closed too loosely or is leaking for some reason. When the cause is more complex, you will have to remove the problematic unit, disassemble it and clean it. Unscrew the clamping nut and remove the air vent. Using a hexagon, unscrew the plug, then remove the rubber band (a needle or screwdriver with a thin tip will do). The piston and spring are removed, and when the float falls out, you need to wash it and then return it to its place (in the reverse order).

A more detailed overview of the Navien Deluxe boiler can be seen in the following video.

Korean-made Navien heating boilers are popular in our country. They are reliable and at the same time affordable in price. Due to the great demand for these devices, setting up a Navien gas boiler is a pressing issue among buyers.

Peculiarities

The Navien Deluxe gas double-circuit boiler has been extremely popular among Russian consumers recently. A pleasant price-quality ratio combined with excellent technical parameters fully explain this preference. It is not at all necessary to choose exactly the 24 kW model in the table of the South Korean manufacturer. But at the same time, it is quite suitable to illustrate the features of devices of this brand.

The company's product range includes wall-mounted dual-circuit gas systems with closed combustion compartments.

Navien Deluxe comes with:

a pair of stainless heat exchangers (for heating and water circuits, respectively);

pump for pumping;

another valve equipped with three strokes (switching operating modes);

a number of other parts that support the uninterrupted operation of the heating unit.

The boiler monitors not only the temperature in the heating circuit, but also the flow of liquid through it. The expansion tank is made in the form of a flat product. A device is provided for air release; a differentiating relay is always installed. The system has a fan, electric ignition is organized using a transformer. Separate electrodes provide ionization and ignition itself.

Specifications

Important! The model is equipped with a closed firebox with an outdoor cold air intake

Deluxe Coaxial 16K

This is a wall-mounted model with a closed combustion chamber and two heating circuits. The turbocharged fan changes speed based on a signal from the built-in air sensor, which ensures complete combustion of fuel in the firebox, which reduces heat loss through flue gas emissions and increases the efficiency of the installation to 91%.

Benefits of Deluxe Coaxial 16K:

• High performance for hot water supply and heating;
• low contamination of the coolant in the heating system;
• low maintenance and repair costs;
• room temperature control;
• Russified control panel with a large LCD display;
• optimal balance of the gas-air mixture;
• innovative mode of modulation of the gas burner device;
• high-quality warranty service;
• easy setup of the Navien boiler;
• low cost of chimneys and gas transmission systems.

Connection and setup

The connection size for the heating circuit is ¾, and for the water supply – ½. Gas is also supplied through a ½-inch channel. Before installing the boiler into an already installed system, you must, of course, turn off the heating and drain all the water from the circuit. Recommended power supply parameters are 230 V and 50 Hz; deviation from them has a negative effect on the product.

Not only interruptions or breakdowns are likely, but also a fire.

When installing the system yourself, it is prohibited to connect any other electrical appliances in parallel to the boiler. The use of extension wires and adapters is not allowed. It is better to design the home's power supply circuit from the very beginning, taking into account all the necessary requirements. Instructions from the manufacturer indicate the great importance of ventilation of the boiler room. It should not just be powerful, but designed at a professional level.

Before starting, check the water connection and the position of the control valves. You cannot think that if the boiler is stopped for 2 or 3 days, it can be turned off. Lack of power supply can lead to the appearance of ice inside the boiler and in the heating system, which has an extremely bad effect on them.

The “Smart Tok” modification provides a switch from winter to summer mode. By selecting the latter, users indicate to the system that it will only be used to generate hot water.

The water temperature is set by rotating a special knob. This indicator cannot be adjusted while using hot water supply. If necessary, you can set a program for heating the water in the water supply circuit as quickly as possible. When you turn the knob, a new dose of information appears on the information display. For simple radiators, you can set temperatures from 48 to 76 degrees, for heated floors under concrete - from 26 to 60 degrees.

Tips and recommendations for operating the Navien boiler

The main advice from experts regarding the safe operation of the boiler:

1. The room where the unit is located must have good ventilation.
2. The unit must have a separate independent connection to the electrical network.
3. The boiler must operate in a fully assembled and protective housing.
4. The user is prohibited from independently repairing the gas equipment of the boiler.
5. The boiler must undergo an annual inspection by representatives of Gorgaz.
6. The boiler owner must periodically check the joints of the boiler and the gas pipeline for leaks with a soap solution.

Additional Information. If leaks occur, immediately turn off the gas valve, ventilate the room and call the emergency gas service.

How they work and what are the advantages of Navien Ace gas boilers

To set the desired temperature, use the “+” and “-” buttons with the “radiator” icon flashing. The possible range is from 40ºC to 80ºC. Once the temperature is set, it will be automatically saved. The “radiator” icon will blink for a few seconds, after which the actual temperature of the coolant will be displayed on the screen.

Heating with air temperature control

To set the desired air temperature in the room, you need to hold down the “radiator” button until the image “house with thermometer” appears on the screen. It means “Heating with room temperature control” mode.

When the “house with thermometer” symbol is flashing, the desired room temperature is displayed on the screen. When the icon is not flashing, the display shows the actual room temperature.

When the icon is flashing, using the “+” and “-” buttons, the desired level of heating in the room is set, adjustable in the range of 10-40ºC. The temperature is then automatically saved and the icon stops flashing.

Setting the hot water temperature

To set the hot water temperature, you need to hold down the “water tap” button until a similar flashing symbol appears in the right corner. You can then set the desired hot water temperature between 30ºC and 60ºC. The settings will be automatically saved and the “water tap” symbol will stop flashing.

Note! In the “Hot water priority” mode, the water heating temperature is regulated differently. Now let's look at how to configure the Navien Deluxe gas boiler in the "Hot water priority" mode

To activate it, hold down the “water tap” key until the “faucet and light” symbol appears on the screen. Now you can set the desired temperature using the “+” and “-” keys. When changing the DHW temperature, the “water tap” icon should flash above the “tap and light” symbol.

Now let’s look at how to configure the Navien Deluxe gas boiler in the “Hot water priority” mode. To activate it, hold down the “water tap” key until the “faucet and light” symbol appears on the screen. Now you can set the desired temperature using the “+” and “-” keys. While the DHW temperature is changing, the “water tap” icon should flash above the “tap and light” symbol.

The “Hot water priority” mode involves preparing a supply of water at a given temperature even if it is not in use. It allows you to supply heated water to the consumer a few seconds earlier.

Away Mode

The “Away” mode means the gas boiler operates only for preparing hot water. To switch the unit to this mode, you need to press the button that shows an arrow and a water tap. The “water tap” symbol that appears on the screen means that the “Away from Home” mode is set. The actual temperature in the room is displayed next to it.

Gas wall-mounted boiler NAVIEN

When a consumer is faced with the question of choosing the right gas water heater for heating, he has to keep in mind a considerable number of parameters that ensure its effective and economical operation. In this regard, it is necessary to divide domestic and foreign units. Unfortunately, not all “foreigners” are able to withstand the difficult Russian operating conditions - poor quality of the coolant, changes in gas and water pressure, periodic shutdowns of electrical energy. True, many foreign analogues are currently already adapted to the conditions of our country. For example, the famous South Korean line of “Navien Ace” models with a manual where it is discussed that these boilers are used in Russia.

The Navien Ace brand is a wall-mounted version of a double-circuit unit. A similar model refers to Navien equipment with an open firebox and real exhaust of combustion products. What is included in the boiler design?

Boiler equipment

The design of the unit includes:

• Two pipe coils are made of stainless steel, this ensures their long and good operation.
• Remote monitor of the control unit, which is completely Russified. For the Russian consumer this is a very important condition.
• Built-in circulation pump.
• Expansion tank.
• Valve for protection.
• Mayevsky crane operating in automatic mode.
• Bypass valve, which can also be adjusted in automatic mode.
• Traction meter.
• AC stabilizer.
• 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 small device with impressive technical properties. The operating instructions for Navien boilers make it easy to understand all the details of setting up the device, modes and temperature ranges.

Classification

Gas boilers “Navien Ace” are divided into two categories:

The first device is a simple convection boiler with an open firebox, where the weather removal of combustion products is used. The second is more improved and has a turbocharged burner. This makes it possible to supply gas very efficiently and burn it during unstable supply, which is associated with pressure surges. Also, another option is equipped with a specialized 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.

Two models can be classified as multifunctional equipment. Adapted to difficult operational requirements, they are one of the very economical radiator designs that are currently on the Russian market. A significant component of the design is the remote control. This is quite convenient when you can set modes and indicators from a distance, quickly making adjustments.

However, what is unusual is that Navien gas boilers will usually operate not only in automatic mode, but also in manual mode. This is even more comfortable when the temperature outside the window changes sharply. Manual installation makes it possible to more accurately set parameters and indicators, which eliminates the smallest errors during operation of heating equipment.

Navien ace gas boilers can be called multifunctional units. They operate on natural gas or liquefied bottled gas. To switch from one type of gas to another, only the burner should be replaced. No other changes will be required.

What should you pay attention to during installation?

Steel gas boiler Navien Ace

Since instructions are included with the equipment, there are no difficulties with installing and connecting the device. Doing it on your own is not a problem. Even an amateur can understand the instructions. Moreover, it is written in Russian.

The only thing that professionals ask you to pay attention to is the method of removing carbon monoxide. They can be removed through a simple weather-resistant chimney connected to the house's smoke exhaust system or installed as a separate structure. However, if you are not satisfied with any option, you can create a coaxial type chimney. Its installation is many times easier. But keep in mind that coaxial structures are used exclusively in cases where the heated area of ​​the house will not exceed 110 m2. They can be installed with boilers whose power will not exceed 11 kW.
