How to choose an Arderia gas boiler: review of models with their technical characteristics and customer reviews

Refusal to use centralized heating and water supply lines, the creation of autonomous heating systems and hot water supply at home is becoming commonplace.

This is convenient for owners of private houses or apartments; it allows them to independently make decisions about the beginning and end of the heating season or home heating modes.

Retail chains offer a wide range of gas boilers, on the basis of which the most efficient and economical heating systems are created.

European companies are considered confident leaders in the production of heating equipment, but their colleagues from Southeast Asia have achieved considerable success.

Let's consider the brightest representatives of heating equipment from South Korea - Arderia gas boilers.

The best floor-mounted voltage stabilizers for a gas boiler

Floor-standing placement expands the options for manufacturers to equip stabilizers because there is no need for a compact housing or low weight.
Often in this category you can find very powerful models up to 2000 W, but there are also quite compact ones with 500-600 W. Floor stabilizers can be installed under a table, on a table, or on a special shelf. They are often placed in a niche or bedside table. This eliminates the need for owners to drill into walls and lay wires and cable ducts. The efficiency of such models varies from 85 to 97%. Interaction with the input voltage range can be from 140 to 270 V.

Why do buyers choose Arderia?

A gas boiler of this brand, which can please with its excellent performance characteristics. Each model harmoniously combines innovation and time-tested technologies, practicality and aesthetic appeal of equipment. Arderia devices are a set of unshakable advantages, among which it makes sense to mention the following:

• Each Arderia wall-mounted gas boiler undergoes multi-stage quality control during the production process, which guarantees that the equipment meets international standards. The Daesung company practices “Japanese” methods of regulating the labor of workers, which means that each employee bears personal responsibility for the unit he assembles. Naturally, with this approach you can expect excellent quality of equipment, which is confirmed by thousands of satisfied customers.
• Each wall-mounted gas boiler is equipped with two heat exchangers, which significantly extends its service life. Today, few manufacturers practice this approach, preferring to equip their equipment with a biometric heat exchanger. This design makes the equipment operate particularly efficiently, even during long-term continuous operation. One heat exchanger is made of first-class copper and is used for hot water supply. The second is made from high quality stainless steel and plated with copper. Its purpose is to heat the room. Of course, this design feature immediately affects the efficiency of the unit and also extends its service life.
• Boilers under the Arderia brand have modern protection systems that make the equipment as safe and stable as possible. The presence of such innovations allows in many cases to avoid accidents.
• Devices of this brand are equipped with a special 5MP5 voltage control chip. This allows the boiler to fully function without any problems at a mains voltage in the range of 150-286 Volts. In addition, even if this indicator drops to 140 Volts or rises to 320 Volts, the equipment will continue to function for some time. This suggests that the Arderia boiler is not afraid of electrical networks in which the voltage is unstable. The equipment is fully protected from power outages. This will be appreciated by buyers living in cold regions of Russia.
• The presence of a DC fan in boilers. This feature allows you to adjust the operation of the air blower, focusing on the diameter of the chimney. Of course, a DC fan makes fuel combustion much more efficient, which immediately affects the efficiency of the unit. This design feature makes it possible to select the optimal boost mode.
• The manufacturing company equips Arderia gas heating boilers with a pump with a dry rotor, which eliminates contact of the coolant with the electric motor parts. This makes the equipment more reliable and significantly extends its service life. The user can be completely confident that the risk of clogging and jamming of the unit is reduced to a minimum. In addition, the efficiency of a boiler equipped with a dry rotor pump is noticeably higher than that of similar models with a wet rotor.
• Each Arderia device is designed to operate at a minimum gas pressure in the system. This feature of the South Korean brand’s products makes it very popular in the CIS countries, where the problem of unstable gas supply is more pressing than anywhere else. In the event of a drop in gas pressure in the central line, you can be sure that your home will not be left without heat and hot water if you have a boiler installed.
• The equipment comes complete with a remote control, which will make working with the device especially pleasant and understandable. This option allows you to receive all the necessary information about the state of the unit, which is displayed on a special display. The remote control will allow you to control the operation of the boiler without leaving the couch.

Price range

The cost of Arderia gas boilers is significantly lower than that of similar devices made in Europe.

For a Russian buyer they cost 23-36 thousand rubles. The price of the unit depends on its power and additional functions. It must be taken into account that the chimney and remote control devices, room thermostat, etc. sold separately.

IMPORTANT!

You should not skimp on warranty service. The danger of being left without heating in winter is much more serious than the costs of concluding a warranty agreement.

Arderia gas boilers appeared on the Russian market relatively recently. Most users do not yet know about them, although a considerable number of units are already in operation.

They demonstrate stable operation, efficiency, and resistance to external loads. Self-diagnosis prevents boilers from malfunctioning; the built-in voltage stabilizer corrects fluctuations in the network. The quality and low cost of Arderia boilers allow them to take their rightful place among alternative options.

Advantages and disadvantages

Advantages:

• efficiency, a successful set of performance qualities;
• the ability to heat the coolant and supply hot water for domestic needs;
• convenient control, there is a remote control and the possibility of remote influence via the Wi-Fi module;
• the presence of a built-in voltage stabilizer capable of correcting drops of up to 150 V;
• boilers are designed for operation in difficult Russian conditions;
• the self-diagnosis system continuously monitors emerging problems and notifies the owner about them;
• there is multi-stage protection against all overloads, coolant freezing, voltage drop, etc.;
• the price of the units is significantly lower than that of European analogues of the same quality.

Flaws:

• need to connect power supply. If there is a sudden shutdown in winter frosts, there is a risk of being left without heating;
• the company emerged relatively recently and has not yet managed to create an extensive network of service centers;
• The power of the units is limited and does not allow their use in large rooms.

Judging by the relevance and high demand, the shortcomings are not critical and are quite surmountable.

CAREFULLY!

Some users note a high noise level or some time lag when supplying hot water. However, such features are typical for all models of gas boilers from European and Russian manufacturers.

Types of devices for home

There are many design options for gas boilers designed for use in autonomous systems.

They are designed for use in different conditions, have several functional capabilities and can be divided according to appropriate characteristics.

According to the set of functions, gas boilers are divided into:

• single-circuit. They are only capable of heating the coolant for the heating system;
• double-circuit. In parallel with heating the coolant, hot water is prepared for domestic needs.

By type of installation:

• wall-mounted Installed in a hinged manner on solid walls or special support frames;
• floor No special installation is required, the maximum is a non-flammable stand.

By type of power supply:

• volatile. To power the control board, sensor system, pump and fan, the boiler must be connected to the network;
• non-volatile. They do NOT require a power supply; they operate only on a mechanical principle.

By heat transfer method:

• convection The usual operating principle is by heating the coolant using a gas burner;
• condensation Before the main heating, the coolant is prepared using thermal energy obtained by condensing moisture from the exhaust smoke. The design is effective only in appropriate conditions, when the difference in temperature outside and inside the room does not exceed 21°;
• parapet. These units themselves are sources of heat, acting like a stove. There are holes on the body through which hot air comes out, heating the room.

By type of combustion chamber:

• atmospheric. This is an old type of combustion chamber where air is taken from the room and smoke is removed naturally through a standard chimney;
• turbocharged. Air supply and smoke exhaust are produced by a built-in turbofan. This type is more modern, clean air is provided in the room, and there is no specific burning smell.

IMPORTANT! All existing structures can demonstrate maximum efficiency and durability only when the appropriate conditions are created. When choosing, you should take into account where and how the boiler will operate, whether it will be able to provide full power and productivity.

GAS BOILER ARDERIA ESR 2.13 FFCD

Arderia boilers are wall-mounted gas boilers with a closed combustion chamber designed for heating and hot water supply with a capacity of 16 to 40.7 kW.

Arderia boilers are produced by the leading heating equipment manufacturer in South Korea, Daesung. They combine efficiency, high quality and exceptional reliability.

Quality control at every stage

Daesung uses the Toyota assembly system in which all employees are personally responsible for each boiler produced. By the boiler number you can easily determine who assembled it, what batch the components were from and who carried out the quality tests. Afterwards, all Arderia boilers are tested in operating mode with the connection of gas, a heating circuit and a hot water supply circuit. From each batch of 500 pieces, 2 boilers are selected for more thorough testing in a special laboratory. After testing, the quality inspector puts his personal stamp on each boiler and if a defect is discovered in the future, all personnel will be personally responsible for this.

Built-in voltage stabilizer

Thanks to the presence of a built-in voltage stabilization system, the boiler remains operational during voltage fluctuations in the range from 150 to 286 volts. No additional installation of stabilizer is required.

Minimum operating gas pressure 4 mbar

Arderia boilers are fully adapted to Russian conditions and can operate stably at a minimum gas pressure of only 4 mbar.

Dry rotor pump

Over time, dirt, scale and rust form in the heating system. This leads to breakdown of wet rotor pumps. Arderia boilers use dry rotor pumps, for which this problem does not exist. In pumps with a dry rotor, there is no contact of the coolant with the rotating rotor of the electric motor, thereby the rotor is completely protected from jamming and clogging. It is also worth noting that the efficiency of pumps with a dry rotor is much higher. All pumps for Arderia boilers are manufactured at a plant in South Korea, which is part of the well-known international Grundfos group.

Supercharging with DC fan

Most boilers use AC fans after the combustion chamber. Such fans can only operate at one speed. But chimneys of different lengths require different pressures, and different amounts of air are needed to burn different amounts of gas. Using an old design fan it is impossible to create the necessary conditions for optimal boiler operation.

Arderia boilers are equipped with a DC fan that can operate at any required speed. It provides optimal air pressure at any given moment. Since it is located in front of the combustion chamber, it does not create a vacuum, but a pressurized air. It supplies the combustion chamber with as much air as is needed for the boiler to operate efficiently.

Protection system

Each boiler has a reliable safety system, which includes: ionization flame control, overheating protection, freezing protection and a self-diagnosis function. All necessary parameters are constantly monitored by the boiler automation.

Two heat exchangers

High operating efficiency is ensured thanks to two separate heat exchangers. The reliable copper primary heat exchanger has a long service life and high performance. For hot water supply, an additional stainless steel plate heat exchanger is used, which easily allows you to obtain the required amount of hot water at any time.

Various types of chimneys

Arderia boilers can be used with different types of chimneys (coaxial chimney 100/60 and separate chimney dy80), to change one type of chimney to another it is necessary to change the special flue mounting flanges in the upper part of the boiler.

Guarantee

The warranty period for Arderia boilers is 2 years. For the production of boilers, only proven, high-quality components and materials are used. Arderia boilers are modern equipment that provides a high level of reliability and comfort.

Maris LLC also pays special attention to the service of Arderia boilers; the necessary spare parts are always available.

Kinds

There are not as many varieties of energy-independent boilers as there are more modern dependent models. For example, there are no turbocharged units (with mechanical air supply).

The following varieties exist:

• single-circuit. They provide only heating of the coolant for the heating circuit;
• double-circuit. They perform two functions - heating the coolant and preparing hot water.

By installation method:

• wall-mounted Installed in a hinged manner on load-bearing walls or durable vertical surfaces;
• floor installed on the floor or a non-flammable stand. Most non-volatile units are manufactured in a floor-standing design;
• parapet. These are units that have the characteristics of several groups of gas boilers. They have a lot of features that make them practical and user-friendly.

NOTE! As a rule, non-volatile boilers have a floor-mounted single-circuit design. This is the simplest and most reliable option

This approach allows us to guarantee an uninterrupted supply of coolant to the heating system in difficult conditions.

Specifications

Let's look at the parameters of Arderia gas boilers:

What is the difference from the usual?

The difference between a non-volatile boiler is the absence of all components that require power supply. There is no built-in circulation pump or turbofan.

Control is carried out using mechanical devices - valves, mechanical sensors, regulators. This makes the design very simple and reliable, but all processes occur naturally.

For example, smoke removal is carried out using a stove draft in the chimney. The air is taken directly from the room. These features make the operating mode dependent on a host of external factors.

For example, the draft in a chimney varies depending on the weather, direction and strength of the wind. Drafts can disrupt the flame. In addition, the room needs good ventilation, since the boiler actively burns oxygen.

Many users solve these problems by installing external devices - a circulation pump and a turbo nozzle to enhance and stabilize the thrust. This makes the operating mode more intense and smooth.

Error codes

If the slightest malfunction or problem occurs in the operation of the device, a certain error is shown on the electronic display.

To properly troubleshoot a problem, you need to know the content of all possible equipment errors.

• Error A1 - failure of the air pressure sensor. This probably occurs due to blockage or icing of the inlet.
• Error A2 - reduced fan speed, as a result of which the boiler does not heat the water well and is also noisy. The cause may be either poor contact, problems with connecting the wires, or foreign objects getting on the fan blades. This may be the cause of the noise.
• Error A3 - the circulation pump is broken, the pressure drops. This problem can occur due to dirt getting into the pressure sensor, or if it turned on before the pump.

• Error A4 - an increase in the temperature of the device, which knocks out both fuses at once. This can happen if the shut-off valves are screwed down, the heating filter is clogged and the valve is leaking, the pump is faulty, the three-way valve is not working, or the water flow sensor is damaged.
• Error A5 - coolant pressure decreases. It may occur due to a decrease in the amount of water in the system, the appearance of air, pump failure or a decrease in its speed, or wear of the pressure sensor.
• Error A6 - no ignition, the boiler does not ignite and goes out. Occurs due to blockage of the chimney, low gas pressure, inoperability of the gas valve, breakdown of the transformer, or blockage of the gas duct.
• Error A7 - the gas valve is broken, as a result of which the unit does not start. This breakdown occurs due to the relay closing, errors in the control system.
• Error A8 - flame extinction. This happens due to the presence of a residual flame when the gas valve is turned off, damage to the gas valve diaphragm, or failure of the control unit.

Repair

Of course, thanks to the control panel and the display, which displays the code for an error that has occurred in the gas boiler, it becomes possible to quickly eliminate it. You can do this yourself or use the help of professionals or a service center.

To get rid of the problem yourself, you can use the following methods to eliminate the most common errors in Arderia gas heating boilers.

• When disconnecting the chimney pressure sensor, the outlet must be cleaned.
• If there is a decrease in fan speed, you need to check for foreign particles on its blades. After cleaning it, the problem will be solved.
• When the overheating sensor turns on, it is better to replace the DHW heat exchanger.
• If low pressure occurs, it is necessary to check the functionality of the pump, as well as the tightness of all valves. You may have to remove the old gaskets and install new ones, be sure to take into account the sizes of the O-rings, and also change the valve. This will help correct the error and increase the pressure in the boiler.
• If ignition blockage occurs, it is necessary to remove the gas valve spare parts and check their functionality. They may need to be replaced.
• If the boiler is not turned on but the burner is working, you need to check the settings of the electronic control unit: it could be broken. In this case, it will have to be replaced.
• If sudden changes in water temperature occur, you need to clean the filters and also check the pump and water flow sensor.

Arderia gas heating boilers are equipped with a fault diagnostic system, which allows you to find out exactly what kind of breakdown has occurred, as well as quickly solve the problem. In this case, it is recommended to use the equipment operating instructions.

As for the reviews from the owners of these units, in addition to all the advantages, they highlight some disadvantages, which include:

• boilers operate quite loudly;
• hot water arrives after a long period of time;
• the pump and control unit may become unusable ahead of time;
• simple and uninteresting boiler design.

To learn how to carry out preventative maintenance on the Arderia boiler yourself, see the following video.

Refusal to use centralized heating and water supply lines, the creation of autonomous heating systems and hot water supply at home is becoming commonplace.

This is convenient for owners of private houses or apartments; it allows them to independently make decisions about the beginning and end of the heating season or home heating modes.

Retail chains offer a wide range of gas boilers, on the basis of which the most efficient and economical heating systems are created.

European companies are considered confident leaders in the production of heating equipment, but their colleagues from Southeast Asia have achieved considerable success.

Let's consider the brightest representatives of heating equipment from South Korea - Arderia gas boilers.

Features of Arderia equipment

Security and full automation are the main areas on which all efforts of developers are directed. That is why the design provides several additional protective devices. In general terms, the Arderia boiler has the following design advantages:

1. Arderia double-circuit boilers are equipped with two independent heat exchangers. A copper heat exchanger is used for the heating circuit. A stainless steel heat exchanger is installed for the DHW system.
2. Installing a pressurized burner allows the automation to independently control the power of the generated thermal energy. This also involves a forcing fan, which provides the necessary amount of air for stable combustion.
3. Simple and clear automation control: you can adjust and set the required temperature values ​​for heating and hot water in just a few clicks.
4. Connecting a room thermostat allows you to control the boiler operating modes remotely.
5. The modern wall-mounted arderia boiler has an electronic display, which displays current values ​​and error codes in the event of a malfunction.

Adaptive Design Features

In addition, gas boilers of the arderia brand are fully adapted to operating conditions in Russian systems. For this purpose, the design of the device provides the following additional elements:

• The main breakdown of volatile double-circuit boilers is voltage surges, which happens quite often in our country. The manufacturer took this into account and the Arderia boiler has a built-in voltage stabilizer. The reliable operation of such a stabilizer is maintained at values ​​from 150 to 285 volts.
• The design also includes a special gas valve and reducer, which are capable of ensuring operation of the burner when the gas pressure drops to 4 Bar.

Such design features were duly appreciated by domestic consumers, which is confirmed by positive reviews on forums and the manufacturer’s official website.

Performance characteristics

Let's look at the main technical characteristics indicated by the user manual:

• A closed combustion chamber, in addition to its efficiency, increases the safety of gas equipment, since combustion products cannot leak from it.
• A coaxial chimney with a forced fan ensures stable and reliable removal of exhaust gases in all weather conditions.
• Protection against voltage surges and anti-freeze system.
• A powerful, yet compact circulation pump ensures pumping of coolant through a heating system of any complexity and configuration.
• Electronic system for automatic ignition of the burner. In addition, the electronics provide smooth start-up and control over the flame.
• The control module has an electronic display, thanks to which the Arderia boiler is easily adjusted to the required comfort indicators.

Positive design features

Let's consider the characteristics of individual components of these heating systems.

Heat exchangers. The presence of copper heat exchangers in the primary circuit significantly increases the home heating performance. At the same time, the secondary circuit heat exchanger is made of stainless steel. The decision, dictated by the desire to reduce the cost of the unit, actually results in a delay in the flow of hot water at the outlet of the boiler. Monitoring operating voltage in the control circuit. A voltage stabilizer is installed in the boilers, which allows the electronics of the unit to function uninterruptedly in a fairly large range - from 150 to 286 V, and in a short-term peak - even more. This option allows the equipment to better adapt to the energy quality in rural areas. At the same time, this increases the service life of built-in automation devices

In general, in the Arderia boiler control scheme, increased attention is paid to safety issues: for example, the protection system controls both overheating and freezing of the boiler, controls the quality of the flow of combustion products through the chimney, and prevents possible gas leaks. Pressurization of external air, which improves fuel combustion conditions and thereby increases the efficiency of the boiler, is implemented in Arderia units using a fan that operates on direct current. Although this complicates the control circuit, it allows you to optimize the number of fan shaft revolutions depending on the required gas pressure

As a result, the service life of this unit increases. The circulation pump from the Grundfos brand operates according to a dry rotor design. This design of the unit reduces its sensitivity to the coolant flow conditions in the pipelines, since various deposits inevitably form there over time, impairing the lubrication of rotating parts. Thus, the operating conditions of the pump are improved.

Startup and operation procedure

• The required temperature is set on the control panel.
• The temperature sensor automatically turns on the boiler, which begins to function until the room temperature reaches the set values.
• Next, the control sensor turns off the boiler, cutting off the gas supply to the fuel-burning device.
• When the coolant temperature in the network drops by more than 15°C, the boiler turns on automatically, after which the operating cycle is repeated.
• The pressure of the coolant and gas in the boiler during all of the above processes is controlled by the air release valve, as well as by the valve that controls the gas pressure. All functions of monitoring and controlling the operation of the unit are implemented using a remote control panel.
  

  Possible malfunctions and ways to eliminate them

  The remote control panel allows the user to make appropriate decisions based on the so-called “error code”. For Arderia gas boilers, such malfunctions occur most often.

  1. The pressure sensor turns off and the chimney blows out - occurs when it is clogged or the external outlet is icy.

  An unacceptable reduction in fan speed occurs in case of careless installation or when foreign particles enter the fan.

• The overheating sensor is triggered when the circulation pump fails or the valves that control water flow are closed.
• Unacceptable decrease in pressure in the primary circuit - the cause is insufficient coolant supply, possible leaks in the pipelines or pump malfunction.
• Ignition blockage occurs when there is no gas supply, the gas valve or gas duct is damaged.
• The presence of a flame on the burner when the boiler is turned off is a consequence of a malfunction of the electronic boiler control unit.
• Abnormal range of operating temperatures of the coolant - occurs when the filters are clogged, the pump fails, the water flow sensor or valves supplying it are faulty.

Basic faults

The main malfunctions of Arderia boilers should be considered:

• if the outlet hole becomes icy, the pressure sensor may be turned off and the chimney may be blown out;
• stopping or falling fan speed means the entry of foreign objects or particles into the working space of the impeller;
• the overheating sensor is triggered when the circulation stops (pump failure) or the supply valves are closed;
• the boiler does not light up. This indicates a failure of the gas equipment (valve) or a power outage to the main line.

All problems that arise are immediately detected by the self-diagnosis system . It issues a special code on the remote control, which indicates a standard situation with a malfunction of a particular sensor, component, or part. A complete list of codes is contained in the user manual, which should be kept at hand.

Among them, the most common designations are the following::

Errors in Arderia gas boilers and methods for eliminating them

Any gas boiler needs regular maintenance and preventive measures. It happens that the causes of problems are external factors: low pressure in the line, voltage drops, etc.

Malfunctions of Arderia gas double-circuit wall-mounted boilers are detected in the form of codes on the screen. Their decoding is available in the operating instructions.

Check for the presence of reverse draft; if there is any, the cause of the occurrence should be identified. Perhaps you need to put a deflector on the pipe or change the design of the chimney

Appears due to a malfunction of the element, a break in its wiring

Perhaps ice has appeared at the end of the coaxial pipe, preventing smoke from escaping from it

Often occurs if the pressure sensor is clogged

If necessary, clean and connect the wires

The reasons are as follows:

• pump failure;
• 3-way valve failure;
• failure of the DHW flow sensor.

All heating system shut-off valves may be closed

Unblock the circulation pump and clear its visible parts of debris.

Open shut-off valves.

Check the functionality of the three-way valve and the DHW flow sensor.

Replace broken items

• lack of fluid in the heating system;
• air jams;
• malfunction of the circulation pump or flow sensor

It is necessary to remove air pockets using Mayevsky taps.

The speed of the circulation pump impeller should be adjusted.

Replace faulty elements

Usually the reasons are:

• low gas pressure;
• malfunctions of the gas valve or transformer;
• blocking of the gas duct

Operating and setting instructions

The initial (basic) setting of gas boilers is carried out at the manufacturer. During installation and first start-up, it is necessary to correct the factory settings in order to combine the existing operating conditions with the needs of the mechanics and electronics of the boiler. These actions must be performed by employees of service centers or warranty workshops.

Independent intervention in the design of gas appliances is prohibited . Operating settings such as adjusting the temperature or turning off the heating for the summer are permissible and must be carried out by the user.

Operation of the units is not difficult . It is necessary to pay attention to the display readings and, if necessary (if an error code appears), call a technician. Clean the housing from dust and dirt, carry out technical inspection and other procedures in a timely manner. Before starting work, you should carefully study the instructions and follow their instructions.

However, existing requirements and strict European standards have done their job - Protherm products are not inferior in quality to the products of the parent company. The Protherm Panther 25 KTO boiler (2015) has a power of 25 kW and is capable of heating 250 sq.m. usable area.

Its characteristics:

• coolant temperature - 30-85°;
• system pressure - up to 3 bar;
• gas consumption - 2.8 m3/hour;
• dimensions - 440x800x338 mm;
• weight - 41 kg.

It is noteworthy that Protherm boiler groups are named after groups of animals.

Thus, wall-mounted gas boilers represent a “cat” line, where all series have corresponding names - Lynx, Panther, Jaguar, etc.

Series and models

Arderia gas boilers are available in the following series:

Series "B"

“B” series units are manufactured in Russia, at Daesung’s own production facilities . The model range consists of dual-circuit units with a bithermic heat exchanger made of copper.

The power of the models ranges from 10 to 24 kW, which is suitable for heating rooms from 53 to 250 sq.m.

Main parameters of the models:

• modulating burner;
• ability to work with low inlet gas pressure (up to 4 bar);
• silent circulation pump with a “wet” type rotor;
• there is a self-diagnosis and flame detection system;
• availability of frost protection;
• The units have been adapted to Russian climatic and technological conditions.

Gas boilers of the “B” series are reliable and economical . Each unit undergoes a separate quality control inspection. There is multi-stage protection against operational overloads or freezing.

Series "D"

A series of gas double-circuit boilers with a power of 10-24 kW, capable of heating rooms from 53 to 250 sq.m. Equipped with two heat exchangers .

Primary (main) copper, secondary (for hot water supply) - stainless steel. Parts and materials from the best European manufacturers, as well as the company’s own developments, were used in production.

Specific features of the units:

• possibility of conversion to liquefied gas;
• the gas valve is adjusted via the control panel;
• two options for installing a chimney - separate or coaxial;
• possibility of remote control via an application on a smartphone;
• There are contacts for connecting a room sensor.

The design of boilers in this series is practically no different from the design of the best European models . At the same time, the prices of Arderia boilers are at least two times lower than those of analogues from European countries.

This increases the demand for Korean units and increases their importance in the eyes of buyers.

ESR 13-20 kW

The power of boilers of this series is in the range of 16-18.6 kW . It includes two models - ESR 2.13 and ESR 2.20. In terms of their set of functions, they are dual-circuit units with a closed combustion chamber. Designed for heating rooms from 65 to 200 sq.m.
