Advantages and disadvantages of Navien Deluxe
Boilers have been sold on the world market for more than 30 years. They have gained popularity due to their reliability and functionality. A high level of safety of gas equipment is ensured by several protection systems:
- From freezing of the heat supply system, with a prolonged shutdown of equipment in the cold season.
- From destructive modes of operation of the electrical network, with voltage surges.
- From low operating modes of the gas network.
- From emergency modes of operation of the water supply system, with a decrease in the pressure of the coolant to 0.1 bar.
The safety group of the Navien boiler contains primary sensors for temperature and pressure, a control pressure gauge and a safety-relief valve against overpressure in the heat supply circuit. To protect the internal surfaces of water heating from scale, a water purification filter from hardness salts is installed.
An SMPS chip is built into the electronic board of the boiler control system, which protects the boiler equipment from fluctuations in the network +/- 30% of the normal voltage of 220V.
To the minor disadvantages of this brand of heating sources, Russian users attribute a rather high price, volatility and complex installation of a gas boiler, which must be performed by a specialized organization.
What are the advantages of boilers Navien Ace
Navien Ace is a double-circuit version of a wall-mounted boiler. It is equipped with an open combustion chamber with a natural release of combustion products. The instructions for their operation speak eloquently about the advantages of Navien boilers - they work even in those conditions under which the equipment of competitors fails.
Did you know?
To increase the service life of Navien boilers, they are made of stainless steel, since stainless steel has a sufficiently high thermal conductivity.
Among the main advantages of the Navien Ace boilers, it should be noted:
- versatility;
- simplicity of control commands;
- compactness;
- high quality anti-corrosion material is used in the production;
- fully electronic, Russified control system;
- compliance with high European standards (quality, comfort, safety);
- reliability and resistance to various conditions (voltage surges up to 30%);
- the ability to work in a frankly emergency situation (low pressure level of gas and liquid heat carrier, low-quality gas, unstable pressure in the water supply system);
- economical fuel consumption;
- environmental friendliness (mainly carbon dioxide is emitted);
- acceptable price.
Important!
In the event of power surges in the unit, the SMPS function is triggered and the boiler continues to operate smoothly.
Specifications
Modern Navien units are equipped with a remote control panel, which receives a signal from a temperature sensor.
Its readings are instantly transmitted to the chip of the control unit, which gives a signal to the actuator to increase / decrease the flow rate of gas supply to the double-circuit boiler. Similarly, a command can be issued to completely shut down the unit if an emergency situation arises in its operation.
The most popular modifications of Navien gas boilers are two-circuit wall-mounted units with a closed firebox, with a thermal power of 20-24 kW, capable of high-quality heating of a room from 160 to 240 m2 and preparing hot water for the household needs of a family of 4 people.

What to look for during installation?
Since the instructions are attached to the equipment, there are no problems with installing and connecting the device. Doing it yourself is not a problem. Even a layman can understand the instructions. Moreover, it is written in Russian.
The only thing that specialists ask to pay attention to is a way to remove carbon monoxide gases. They can be discharged through a conventional atmospheric chimney, connected to the chimney system of the house or installed as a separate structure. But if you are not satisfied with either option, you can make a coaxial chimney. Its installation is several times easier. 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 with a capacity not exceeding 11 kW.
Basic errors and their elimination
Gas boilers are equipped with a good diagnostic system that scans the parameters of the boiler every minute and, in the event of their violation, issues a coded signal to the operating panel to eliminate the malfunction:
The main codes for the failure of gas boilers Navien:
- E01 - overheating of the coolant in the boiler. Insufficient water circulation through the device, it is necessary to check the operation of the pump, the presence of leaks and blockages in the heat exchanger. If the latter is found, before eliminating the error, it is recommended to flush the heat exchanger from scale using the technology specified by the manufacturer.
- E02 - error 02, low coolant pressure in the heating circuit. Check for leaks in heating networks, if necessary, recharge the circuit.
- E03 - problems in the boiler electric ignition system. It is necessary to check the presence of power supply in the system, the presence of pressure and the electrode for the presence of a spark.
- E04 - there is no flame in the boiler. Control of the piezo igniter for the possibility of generating a spark and checking the grounding system.
- E05 - the temperature sensor of the return heat carrier at the inlet to the device does not work. Check the performance of the primary temperature sensor and, if necessary, replace it with a similar version.
- E06 - the temperature sensor of the supply heat carrier at the outlet of the boiler does not work. Check the performance of the primary temperature sensor and, if necessary, replace it with a similar version.
- E07 / 08 - the DHW temperature sensor does not work at the inlet or outlet of the boiler. Check the performance of the primary temperature sensor and, if necessary, replace it with a similar version.
- E09 - the centrifugal fan does not work. Check the operation of the inlet air filter for clogging.
- E10 - error 10, problems in the chimney system, there is no vacuum in the boiler. The gas outlet channels are monitored for blockages.
- E13 - error 13, problems in the circulation circuit.
The most frequent malfunctions and elimination of problems in the operation of the boiler
With its functionality and provision of electronics, there are certain drawbacks and malfunctions that can be encountered when operating the Navien Ace boiler.
Most often, users face a problem when the unit stops working, and the electronics signals a critical error. This situation can be caused by various factors, including the sensitivity of the sensors. The most common mistakes are:
- Exhaust.
Fault code "10" indicates problems with the removal of combustion products. Possible reasons: turbine malfunction, pressure sensor tubes are incorrectly connected, chimney is clogged, branch pipe is too long.
If none of these reasons are identified, and the Navien Ace boiler continues to signal an error, then ordinary gusts of wind may be the cause. You can solve this problem by redoing the chimney. As an option for a quick response, you can open the boiler drum and disconnect the air supply hose. However, this measure is temporary. For frequent errors on the "Navien" gas boiler, see this video:
- Flame sensor failure.
DTC "03" may indicate poor gas quality. The problem can only be solved by elimination. First of all, the cleanliness of the gas supply nozzles is checked. If they are in order, you need to select the optimal position of the controller electrode (it should be in the hot phase of the flame). - Overheating of equipment.
Fault code "01". A possible cause is a blockage in the heating system, a malfunction of the circulation pump or a decrease in flow. Ways to solve the problem: check the system and filter for the presence of air, check the serviceability of the pump and the resistance of the coil for a short circuit, check the impeller in the circulation pump. - Gas boiler Navien is working, there is heating, but no hot water.
Error code "02". A jump in water temperature is observed on the control panel (it rises sharply to a maximum and instantly drops). There may be a blockage in the hot water supply system. The reasons may be: lack of pressure in the water supply system, airiness of the system, the circulation pump cannot pick up speed, the distribution valve is closed, or the flow controller does not work. To eliminate this malfunction, first of all, it is necessary to adjust the pressure, bleed the air in the system, check the resistance of the pump coil and the impeller for damage, open the boiler control valve, disassemble the regulator body and clean the flag.
In addition, when hot water is turned on, the Navien boiler may hum or make an incomprehensible noise. At the same time, there is no information on the error on the display and the pressure is normal. As a rule, this is due to the clogging of the heat exchanger. In order to fix the problem, you can clean the heat exchanger or replace it.
Did you know?
It is best to choose boilers that are equipped with smooth control - this will allow you to change the performance depending on the air temperature.
Gas boilers Navien Ace are distinguished by high quality indicators and reliability in operation. However, the duration and features of operation depend on how correctly you were able to install and configure the Navien Ace boiler, as well as on the quality of the fuel used.

The Navien boiler is a high quality South Korean heating equipment. The company is engaged in the production of modern gas boilers.These products quickly gained the confidence of consumers, became a regular participant in the domestic market, significantly expanding the ability of buyers to choose the ideal boiler for themselves.
Photo of the Navien boiler
Wall-mounted and floor-standing boilers from Navien have a number of features that set them apart from competitors.
- System for working with power drops. Navien models of gas boilers are distinguished by the presence of technical filling, which allows the equipment to operate even with drops in the electrical network reaching 30 percent. This is a guarantee that your wall-hung boilers will not need repairs if there is a problem with electricity in the house. And such situations are not uncommon for us.
- Ability to work at low pressure of the plumbing system. Problems with pressure in the water supply system are less common, but even if they occur, the boiler will function normally, providing the whole house with heat and hot water.
- Not one heat exchanger, but two. All wall-mounted models of Navien boilers have not one heat exchanger, but a pair. Each heat exchanger is manufactured from stainless steel, which is reliable, efficient and corrosion resistant. This design with a pair of heat exchangers increases the boiler's resistance to water pollution, scale, and provides affordable repairs. The price of the Navien boilers themselves is quite attractive - from 30 thousand rubles. There are also more expensive, productive models capable of providing heat to an impressive area of \ u200b \ u200bthe room.
- Turbocharging. Each floor-standing and wall-mounted boiler of the South Korean company Navien is equipped with a turbocharged air supply system. This increases the efficiency of the boiler device. The air supply pressure is automatically controlled. As a result, better heating of the house is ensured with less fuel consumption.
Benefits
We talked with you about the design features of Navien boilers. These are four objective reasons to pay close attention to such models as the Navien Ace and Deluxe, Prime boiler.
If we put Navien boilers on a par with competitors presented on the domestic market in approximately the same price range, the South Korean manufacturer will demonstrate a number of obvious advantages:
- High level of quality and reliability of automation. Errors for such boilers are rare and can only be caused by system failures or improper user control. But if errors occur on the Deluxe, Prime or Ace models, fixing them is easy enough. Most of the work is done by automation. Errors are easy to read, the reasons for their occurrence are determined according to the manufacturer's instructions;
- SMPT protection chips. With their help, gas boiler equipment works perfectly under conditions of an unstable electrical network. You all know how often there are problems with the power grid in our homes. Many boilers are not able to cope with such fluctuations, they constantly give errors and fail. With Navien boilers, such situations are minimized;
- Adaptation of Navien boilers to operating conditions in domestic realities. We are talking about unstable pressure in the gas pipeline and problems with water pressure in the water supply system. The Navien boiler of the Prime, Deluxe or Ace models perfectly cope with such conditions, when the gas pressure drops to 4 mbar, and the water pressure drops to 0.1 mbar;
- Real Korean build. Unlike many products that have European or other designations on the bodies, Navien boilers are really assembled in Korea, and not somewhere in China, in order to reduce the cost of assembly. It is no secret that many foreign companies are setting up production in China. And they give out equipment for European, for example;
- Remote controls.Navien boilers are equipped with special convenient remote controls, with the help of which the user can change the operating modes of his boiler equipment at a distance.
Installation and connection
Installation, commissioning and the first start-up of any modification of the Navien gas boiler must be carried out by the service department, and the gas equipment must be launched by representatives of the gas company.
However, the owner of the heating equipment will need to know the main points of putting the boiler into operation in order to control the progress of installation and construction work.
The gas boiler is not allowed to be installed in damp, basements without ventilation. Typically, such mounted units are installed in kitchens, if free space allows, and floor options in a special furnace.
Basic rules for the location of the wall-mounted boiler Navien:
- The boiler is installed on a solid wall made of heat-resistant materials.
- The gap from the front of the boiler to the opposite wall must be at least 1.0 in order to be able to service the device.
- The gap from the boiler to any electrical appliance must be at least 0.6 m.
- The gap between the side surface of the boiler and the walls must be at least 0.2 m.
- The gap between the floor level and the lower plane of the boiler must be at least 0.8 m.
- The unit must have an independent power supply line 220V / 50Hz.
- The boiler body must be grounded without fail.
- The room in which the gas apparatus is installed must have a 3-hour supply ventilation system.
Range
The assortment of the South Korean company Navien is constantly expanding, which allows customers to purchase for themselves gas boilers that are optimally suitable in all respects.
Therefore, it is impossible to tell about all the representatives of the lineup. Instead, we'll look at Navien equipment, which can be divided into three broad categories.
- Wall models. Wall mounted boilers have a double heat exchanger, marked as Ace, Deluxe. Deluxe are two-circuit models that have a wide power range up to 13 to 40 kW. All boilers of the Deluxe series are turbocharged. The deluxe turbo equipment can have a coaxial or split chimney. In addition to the 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 Turbo is fully adapted for operation in conditions of non-steel supply of gas and electricity to the boiler. An additional advantage of Ace Turbo is the anti-freeze protection and turbocharging of the burner. If we talk about Atmo, then this is a classic gas boiler that perfectly provides heating for a private house. Atmo has all the strengths of the Turbo except for the turbocharging of the burner.
- Floor standing boilers from Navien. If the wall models do not suit you for one reason or another, the floor models deserve excellent reviews. They are used for heating and hot water supply of private houses. The distinctive features of the floor-standing models of Navien boilers include their compact size, ease of use and convenient installation. Each boiler is accompanied by detailed instructions, according to which even a beginner in such matters will be able to install. Wall-mounted models are somewhat easier to install, although there are no problems with them. The double heat exchanger significantly improves the heat generation efficiency in the gas boiler.
- Condensing. Deluxe, Ace and other models of the Navien company not so long ago received a serious competitor in the form of condensing South Korean boilers. They are marked with NCN. Their distinctive feature is the 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 the Navien condensing boilers reaches 108 percent.This was made possible by using the heat that is released during the condensation of steam. This way consumers save money on paying for gas, but they heat their own home more efficiently. The heat exchanger here is somewhat different. Its design is unique, it is distinguished by the presence of a system for preliminary creation of a combustible mixture. Burners are necessarily modulating, the range of operation of which is amazing.
Choosing boilers from the Navien company from the Deluxe series, Ace or other assortment, you buy quality and reliability. This is one of the few cases where the manufacturer does not require more just for the brand. The high level of Navien boilers is beyond doubt.
Practicality and reliability in combination with an affordable price are the main advantages of Navien double-circuit gas boilers. The owners' comments about this manufacturer, which appeared on the heating equipment market quite recently, are surprisingly positive - which others cannot boast of.
The manufacturer applies unique developments, quickly learns from his mistakes, making adjustments to the design of devices. have a very attractive design.
The manufacturer is ready to provide the end consumer with a fairly wide range of gas boilers, but the Russians are especially fond of the brothers - Navien Ace 24k and Navien Ace 16k, differing only in power: the first has 24 kW, and the second - 16 kW.
The fundamental difference
As for the fundamental differences relative to other global brands, it should be noted that Navien engineers are not afraid to experiment, supplying their devices with new or improved technological solutions. So, the latest models of this Korean manufacturer use:
- Expanded simulated turbocharging system.
This technology is based on the idea of reducing heat loss. This is realized using the Air Pressure System air pressure sensor. The turbocharging system provides for the installation of a fan directly below the gas combustion chamber.
The fan is controlled by an APS sensor.
Thanks to this technology, air is supplied to the chamber in a certain ratio, which significantly reduces the amount of gas consumed. Thanks to this technology, stainless steel heat exchangers have a higher efficiency, which is better than other copper heat exchangers.
If we talk about the real efficiency of the above, then for the Navien Ace 16k boiler, the instruction determines the efficiency of 91.2%, which is a fairly high indicator for gas boilers with a copper heat exchanger.
As for the adjacent model, which has a higher power, for the Navien Ace 24k boiler, the instruction regulates the efficiency at the level of 90.5% with a thermal power of 9-24 kW.
Does this technology deliver real tangible benefits to users? Korean gas boilers Navien, reviews of which are posted on almost every forum and specialized sales sites, indicate that the gas consumption of these boilers is really low, the boilers suit the owners in terms of performance.
However, many users have noted a noticeable increase in the energy consumption required to implement a turbocharging system.
Boiler navien error 03
In gas boilers, the presence of a flame on the burner is checked by a special sensor - an ionization electrode. The logic of the unit operation is to continuously check for the presence of a flame after opening the gas valve. Symptoms of the appearance of error 03 on navien boilers can be conditionally divided into two groups:
- unsuccessful attempts to ignite (no flame appears)
- ignition occurs, but the flame goes out
In the case when ignition does not occur, you need to check:
- gas pressure at the inlet and outlet of the gas valve (can only be carried out by a qualified specialist using special equipment - a differential pressure gauge)
- the condition of the ignition electrodes (compliance of the gap with the manufacturer's standard, contamination of the electrodes). The norm of the distance between the electrodes is 3.5-4.5 mm.
- the integrity of the insulation of the electrode power wire (visually you can make sure that the spark breakdown occurs precisely on the body of the gas burner, and not anywhere else)
- correct setting of the boiler power on the DIP-switch (valid if there is a problem during the first start-up of the boiler or after replacing the electronic board)
- presence of voltage on the ignition transformer
Error 03
on the Navien boiler, it will also appear in case of unstable combustion (intermittent flame) or if the control unit fails to detect the presence of a flame. In this case, it is necessary to make sure that the connection of the ionization electrode to the control board is secure, check the boiler grounding and the absence of contamination on the electrode. Combustion instability can be caused by an even increase in the fan speed, therefore it is necessary to make sure that the yellow hose from the turbine to the APS sensor is securely connected and not damaged.
If during the checks it was not possible to normalize the operation of the boiler, it is more likely that the boiler board will need to be diagnosed, repaired or replaced. We recommend watching a video in which one of the users imitates error 03 on the Navien boiler:
Classification
Gas boilers "Navien Ace" are divided into two categories:
- Ace ATMO.
- Ace TURBO.
The first unit is a simple and traditional boiler with an open combustion chamber, which uses the atmospheric removal of combustion products. The second is more advanced and has a turbocharged burner. This makes it possible to efficiently supply gas and burn it with an unstable supply, which is associated with pressure surges. In addition, the second version is equipped with a special SMPS control system, which is based on highly sensitive chips. They are responsible for the control and regulation of gas combustion processes. In all other respects, both options are no different from each other.
Both models can be classified as universal equipment. Adapted to difficult operating conditions, they are considered one of the most economical heating devices on the Russian market today. An important component of the design is the remote control panel. This is very convenient when you can set modes and indicators at a distance, quickly making adjustments.
But what is surprising is that they can work not only in automatic mode, but also in manual mode. This is especially convenient when the temperature outside the window changes dramatically. Manual installation allows you to more accurately set the parameters and indicators, which eliminates the smallest errors during the operation of heating equipment.
Gas boilers navien ace can be called universal units. They run on natural gas or LPG. To switch from one type of gas to another, only the burner needs to be changed. No other changes are required.
