Nuances of using the Navien Ace gas boiler: main characteristics and malfunctions + owner reviews

Your own heating system in a private house is much preferable to connecting to a central heating system.

Dependence on suppliers, rising tariffs, worn-out networks and other problems disappears.

Installing your own boiler requires a certain initial investment, which subsequently pays off in significant savings on heating the house.

There are high-quality and relatively inexpensive gas devices that provide heating and hot water for domestic needs.

One of these units is the Navien Ace boiler, which should be taken a closer look.

Navien Ace gas boiler series

Navien boilers of the Ice (Ace) series are a family of gas double-circuit units manufactured by the South Korean company KyungDong NAVIEN.

They provide heating to the home and at the same time supply it with hot water. A special feature of Navien equipment is its specialization in Russian conditions, climatic and technological.

It is possible to work at low pressure of gas and water, resistance to changes and sudden surges in pressure.

In addition, there is a protective system that compensates for voltage drops in the power supply network up to 30%.

In addition, the company’s pricing policy is such that the cost of Navien boilers is approximately 2 times lower than European equipment of the same power. Such advantages are highly appreciated by users; the demand for Navien units is stable and gradually growing .

IMPORTANT!

Incorrect operation or difficult operating conditions can damage the boiler in a short time. This is not a consequence of poor quality assembly, but the result of insufficient attention and failure to take proper measures to create optimal working conditions.

Wall-mounted gas boiler Navien ACE ATMO 24AN (Deluxe 24A White)

Navien Deluxe 24A White is a wall-mounted gas boiler designed for heating and preparing hot water in residential premises. The Navien company (South Korea) is one of the recognized leaders in the Asian market in the production of high-quality heating equipment.

Over the past few years, its products have been supplied to the domestic market, receiving only positive reviews from numerous users. An important advantage of Navien wall-mounted gas boilers is that they are created taking into account the climatic conditions of Russia and can be operated in almost any conditions.

The Navien Deluxe 24A White boiler can be easily installed in an apartment, country house or country cottage, using main gas as fuel. If conditions do not allow connection to the main line, the unit can be converted to run on liquefied gas using several jets. An installed Korean-type chimney together with a fan guarantees fast and efficient removal of all combustion products to the street. Also, for operation you will need constant power from a 220 V electrical network.

Advantages of the Navien Deluxe 24A White gas boiler

Low temperature resistance.

A drop in room temperature will not affect the operation of the boiler, thanks to the installed frost protection. The circulation pump turns on automatically when the temperature of the heating water drops to 10°C or more - this ensures non-stop circulation of the coolant. If the water temperature drops 6°C, the burner is additionally turned on, which brings the coolant to 21°C. Navien Deluxe 24A White can be freely installed in utility rooms or utility rooms without special insulation. Built-in weather-dependent automation takes care of maintaining a comfortable temperature in the apartment or house, even if it starts to freeze outside.

Economical gas consumption.

This is achieved thanks to the installed return line sensor - it not only prevents excessive gas consumption, but also significantly extends the service life of the heat exchanger and boiler by reducing the number of on/off cycles. An important advantage of boilers from the Delux series is their adaptability to domestic gas pressure - they are able to operate stably even at low pressures of 4 mbar.

Modulated turbocharging system.

The Navien Deluxe 24A White gas boiler has a turbocharging fan controlled by an APS (Air Pressure System) air pressure sensor. The fan rotation speed is flexibly adjusted automatically: an amount of air proportional to the amount of incoming gas is supplied to the combustion chamber. This technological solution has significantly increased the efficiency of the unit - the gas burns almost completely, minimizing heat loss. The boiler has a stainless steel heat exchanger, which is more durable and resistant to corrosion.

Differences between Navien wall-mounted boiler series

Stable operation even with network fluctuations and low water pressure.

The Navien Deluxe 24A White boiler is not afraid of even significant voltage deviations - even with fluctuations of +/-30% from 230 V, it continues to operate, guaranteeing a high level of safety. It is protected from surges by a special SMPS (Switched-Mode Power Supply) chip installed on the microprocessor and protecting the unit from breakdowns. Also, the stability of the boiler is not affected by low water pressure (up to 0.1 bar), which allows it to be used in places with low pressure.

Remote control.

A remote control panel is supplied with the boiler, allowing you to fully control its operation and set the necessary settings depending on specific tasks. Controlling with this remote control will not cause any difficulties, thanks to the voice assistant function.

What models and what power exist?

The Ace series included the following models:

• Ace Atmo
• Ace Turbo
• Ace Turbo Coaxial

Atmo models had an open (atmospheric) combustion chamber and required an effective smoke removal system.

Their efficiency was noticeably lower, but this was successfully compensated for by installing a copper heat exchanger, which has greater productivity compared to stainless steel units.

The Turbo model range was distinguished by a closed combustion chamber design and turbocharging - a special fan supplied fresh air, increasing combustion efficiency and increasing draft in the smoke removal system.

A Korean or European (coaxial) chimney model was used to remove gases.

The first option consists of two separate pipes - one for air supply, the other is a chimney.

A coaxial chimney is a “pipe-in-pipe” system, where a chimney is installed inside and an air supply pipeline is installed outside.

The power of all models was 10, 13, 16, 20, 24, 30 kW, etc. The most popular models are 16k and 24k, optimally suited for servicing a private home. .

Specifications

The technical characteristics of almost all models (with the exception of the Atmo series) are similar and differ only in the power of the unit.

It corresponds to the heated area - 13 kW boilers are capable of serving 130 m2, 24 kW - 240 m2, etc.

For ease of consideration, the main parameters of Ace series boilers should be summarized in a table:

The difference in performance is due only to the type of combustion chamber and all related design features.

It should be noted that the 16 kW models are a complete analogue of the 24 kW models with reduced software capabilities, which provides a large margin of safety for the units.

Advantages and disadvantages

The advantages of Navien Ace boilers include::

• The optimal combination of price and quality.
• Environmentally friendly process.
• Simplicity and convenience of adjustment and configuration of operating modes.
• Adaptation to Russian conditions, ability to work on unstable gas pressure, water pressure, and power supply voltage.
• Simultaneous provision of heating and domestic hot water.
• Long service life without service checks.

The disadvantages of Navien Ace boilers are::

• Dependence on the availability of electricity, gas and water.
• High noise level.
• Only original spare parts are suitable for repairs.
• The structure is not resistant to hard water.

Most of the shortcomings are not the result of errors or defects during assembly, but rather relate to design features.

They are inherent in almost all gas boilers, regardless of the manufacturer . To prevent the formation of lime deposits caused by excessive water hardness, use electromagnetic softeners or other types of appropriate equipment.

Navien presents a universal water heating system

Navien Ace gas boilers are not afraid of low pressure of gas and water, they are not afraid of voltage drops in the network. The operation of Navien gas boilers is characterized by a long service life and economical gas consumption. All Navien gas devices comply with the standards and regulations of the Russian Federation and have the appropriate certificates.

Frost protection system stability

If the room temperature drops, the automatic protection system is activated

from freezing. When the temperature of the heating water drops by more than 10 degrees Celsius, the circulation pump automatically starts, resulting in constant circulation of the coolant in the heating system. If the temperature of the heating water drops to 6 degrees Celsius, the burner is automatically turned on and the coolant warms up to 21 degrees Celsius.

Safety of operation during frequent power surges

According to the instructions, the voltage can fluctuate within ±30 percent due to the triggering of the Switched - Mode Power Supply (SMPS) protective chip on the microprocessor. At the same time, the boiler operation does not stop

, which prolongs its service life and prevents breakdowns.

Operating conditions for heating and hot water:

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

Rational design

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

Fuel preheating (KR series)

significantly impairs the flammability of diesel fuel

Navien gas devices operate on any Russian-made diesel fuel

However, the cost of winter or arctic diesel fuel is much higher than that of summer diesel fuel, and the use of summer fuel is impossible at low temperatures without preheating it.

The heating element, which is built into the burner of the Navien gas unit, preheats it before supplying fuel to the nozzle, resulting in high-quality fuel atomization and uninterrupted ignition. Due to preheating in Navien Ace gas boilers, it is possible to use inexpensive summer diesel fuel

, which leads to significant savings.

Design

1. The heat exchanger is made of stainless steel

Stainless steel is used to produce the heat exchanger, so it is not subject to corrosion

, which significantly extends the life of the Navien Ace boiler.

2.

Thanks to a modern, efficient diesel burner, low-noise, stable operation with minimal fuel consumption is ensured. According to the instructions , the burner can work with any diesel fuel

, taking into account all types of fuel produced in the Russian Federation.

3. Fuel filter with replaceable cartridges

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

4. Russified control panel

Using a fully Russified remote control panel equipped with a liquid crystal digital display, it is possible to save fuel consumption and reduce heating costs

, as well as constant maintenance of a comfortable room temperature thanks to the room temperature sensor built into the control panel.

Where is it used?

Gas double-circuit boilers Navien Ace series are designed for organizing heating and hot water supply of residential premises or offices of the appropriate area.

This limits the scope of use of these units, although they can be installed in any premises. The main task is to ensure that the serviced area matches the capabilities of the equipment and the availability of all the necessary resources - gas, electricity and water (coolant).

NOTE!

In addition to the area, it is necessary to take into account the volume of the room, which may be too large for this Navien boiler model. The product passport indicates the maximum volume possible for the normal functioning of the system.

Connection instructions

Installing the boiler is not difficult - you just need to install anchor bolts and hang the unit on the wall.

It is recommended to install elastic gaskets between the housing and the wall to dampen noise. Do not install the equipment on fragile or weak structures - plasterboard partitions or other similar surfaces.

You need a solid brick or concrete wall that can support the weight of the boiler (about 30 kg).

Communications should be connected to the appropriate pipes. It is necessary to carefully monitor the compliance and tightness of connections.

The main attention should be paid to connecting gas pipes. Check all connections for leaks using a soapy solution.

If there is a common chimney, separate pipeline connections are used - the air channel is led out into the street through the wall, and the smoke channel is connected to the common chimney of the house.

Coaxial chimneys are led outside through the wall, which is much simpler and more convenient for installation.

User manual

Navien boilers operate automatically and require virtually no human intervention.

The only thing that is required from the owner is to set a comfortable heating temperature. If liquefied gas is used as fuel, it is necessary to ensure timely replacement of cylinders.

The possibility of long-term operation without specialized service checks is a feature of Navien equipment, which is convenient for users and relieves them of concern about the condition of the unit.

If any malfunctions occur, the corresponding error code appears on the display, the water pressure is shown by a pressure gauge, which allows you to timely detect a leak in the system.

The owner may be required to purchase and install a special filter or water softener, which will extend the life of most boiler components - the heat exchanger, pump or three-way valve. If the water supply is from your own well, installing a softener becomes a necessity.

Basic malfunctions and their solutions

Malfunctions of Navien boilers are usually diagnosed independently and displayed on the display with the corresponding code. Based on a signal from one or another sensor, a message about the problem that has arisen is activated.

The most common mistakes are:

• 02. Lack/insufficient amount of water in the system. The issue can be resolved by recharging the system or replacing the flow sensor.
• 03. No flame in the combustion chamber. Indicates problems with the ignition system, or lack of gas.
• 05-06. Open circuit or short circuit of the fresh air sensor.
• 07-08. Open circuit or short circuit of the DHW sensor.
• 09. Fan failure.
• 10. Failure of the smoke removal system.
• 15. Problems with the control board.
• 16. Boiler overheating.

The solution to most problems is to replace the corresponding sensors or components, as well as to clean and remove deposits in the connecting pipelines.

IMPORTANT!

It is not recommended to undertake repairs yourself. This procedure should be entrusted to specialists from the service center or other specialized organization.

Common malfunctions and their elimination

Let's look at the main ways to resolve errors:

E 01-02

This error indicates overheating of the equipment due to the lack of coolant in the system. The solution to the problem is to clean the pipelines or check the pump. Alternatively, it is necessary to remove air from the system (primarily from the pump).

E 03

The functionality of the flame sensor is checked. Cleaning ignition electrodes.

It is also necessary to check the presence of gas in the line or cylinders.

E 05

A malfunction of the temperature sensor can be eliminated by checking its condition. The resistance of the sensor is measured at a certain temperature. If the readings correspond to the standard ones, it is necessary to clean the contacts.

If the sensor readings do not correspond to the table values, replacement with a new, functional unit is required.

E 09

First of all, you should measure the resistance on the fan windings, which should be 23 Ohms.

Check if there is power supply at the terminals. If serious problems are detected, the fan is completely replaced.

E 10

Most often, the problem lies in the sensor itself. It is necessary to check its condition, clean the contacts, and replace it if necessary.

E 13

The flow sensor often gets stuck due to clogging of the actuator with small debris, lime deposits, etc. If cleaning the sensor does not give the expected result, a possible breakdown to the control board is checked.

If there is no result, the sensor is replaced.

E 16

Overheating of the boiler can have several reasons, the most common of which is clogging of the heat exchanger and poor flow of the coolant. The protection is triggered at 98°, the alarm is switched off when the boiler cools to 83°.

There are two ways to solve the problem - first, you should clean (in difficult cases, replace) the heat exchanger; if there is no positive result, replace the sensor.

E 18

Overheating of the smoke exhaust sensor occurs when the chimney is blocked. The cause may be condensation freezing, strong winds from outside, or foreign objects or debris getting into the chimney. If eliminating interference with the output of combustion products does not bring any results, the sensor should be replaced.

E 27

Lack of air pressure when the fan is running most often indicates a clogged air duct or the need to replace the sensor. Most often, the reason lies precisely in this, since the entry of foreign objects into a closed air channel is extremely difficult.

Price range

Prices for gas double-circuit boilers Navien Ace range from 26 thousand rubles. (Navien Ace 13K Atmo), up to 32 thousand rubles. (Navien Ace-24K Turbo). It is necessary to take into account that these amounts constitute only the cost of the boiler itself, without delivery, installation, warranty agreement and other additional costs.

Stores only carry out sales, and warranty repairs and maintenance are carried out by service centers, an agreement with which is concluded and paid separately. Many buyers believe that the warranty is automatic upon purchase, but this is a misconception .

NOTE!

The Ace series has been discontinued. It is still possible to purchase such units, since a lot of them were brought to the regions of Russia. But the possibility of warranty service must be clarified immediately, otherwise you may find yourself in an unpleasant situation.
