Korean gas boilers: floor and wall options

Korean gas heating boilers: getting to know each other better

The entire model range of Vaillant, Viessmann, Baxi, Bosch, ACV, Protherm, RUSNIT, Buderus, Kermi and others is available.

Competent design and installation of turnkey systems.

Call (Moscow and region).

In Russia, Belarus, Kazakhstan, Ukraine and other countries of the former Soviet Union, gas communications are not always in good condition. In this regard, there are frequent cases of pressure drops in gas supply systems. South Korean companies specializing in the production of gas heating systems have successfully coped with this difficult task. Their equipment, supplied to the territory of the post-Soviet space, is rightfully in great demand and popularity.

Buyers who have chosen to purchase products from Korean manufacturers will never regret it later.

Why? After all, many companies from other countries produce similar products.

The answer is simple - Korean gas heating boilers have a number of undeniable advantages.

Pros and cons of boilers made in Korea

Advantages

By paying a little more, you can purchase a sample equipped with a tubular heat exchanger, which is much stronger and more resistant to corrosion, which increases the service life of the device.

Our market offers a wide range of boilers of various capacities. This allows you to select both a wall-mounted heating device for heating small cottages and apartments, and a unit for providing heat to industrial facilities.

I would especially like to note the desire of Korean developers to bring the quality of their products into compliance with all rules, regulations and safety standards. Suffice it to say that some devices in the basic configuration can be equipped with a dozen different protection sensors, while many European manufacturers prefer to include the installation of protective equipment as a separate expense item.

Flaws

Today, the operation of gas heating systems produced in South Korea does not cause any complaints from either specialists or ordinary people. But like any complex technical device, Korean boilers also have disadvantages. They are expressed mainly in the difficulty of restoring working condition in the event of a breakdown. However, it should be noted that it is not the repair itself that causes difficulties, but the selection of failed parts. At the same time, with boilers from other producing countries the situation is somewhat simpler, since you can use components from other manufacturers.

Manufacturers of South Korean gas heating systems

The Rinnai brand delights consumers with a device with a rather unusual design

Nowadays, the leaders in the market for gas heating systems are such Korean companies as Kiturami world, Olympia, Navien, Rinnai, Daewoo. Daewoo company managers do not consider the production of heating systems as a core business, therefore they are inferior to other companies in terms of sales volumes.

A true luminary in this market segment is the Navien company, which has proven itself well with its double-circuit boilers of the ACE ATMO series with an open combustion chamber and a heat exchanger made of stainless steel.

Gas boiler NAVIEN Ace

This design allows combustion products to be removed using natural draft. Combined with the ability to operate in harsh climatic conditions using liquefied and natural gas at a minimum pressure of only 4 mbar and a water pressure of 0.1 bar, the products appealed to Russian consumers.

The fact is that on the top floors of high-rise buildings, due to poor quality communications or the fault of utility services, the pressure in the water supply system is often not high enough. In addition, stable operation is ensured during voltage surges, and in many settlements the electrical networks leave much to be desired.

It’s nice that the boilers of the ACE ATMO and ACE TURBO series have a Russian-language control panel. Also, when purchasing, you can choose a color that matches the design of the room.

Although Korean boilers are in a higher price category than Italian and Czech ones, there is a reason to pay more for comfort, quality and safety!

The most famous brands of boilers made in South Korea

Gas boilers produced by leading Korean companies and firms have appeared on the Russian market. The list is quite impressive - DAEWOO, CELTIC, KITURAMI, KOREASTAR, NAVIEN. All models of Korean gas heating boilers offered by these companies have lower prices than their Western counterparts, with comparable quality and reliability. It is important that all models of Korean-made gas boilers are certified. They combine excellent functionality with a fairly reasonable price, which contributes to their popularity.

Gas boilers from DAEWOO

Household appliances of the South Korean company DAEWOO are known all over the world, so consumers in Russia choose a Daewoo gas boiler as a result of trust in the company.

The Daewoo double-circuit boiler is available in a wall-mounted version. It has an expanded list of protections, several programmable operating modes, small size and a reasonable price. The manufacturer has developed an operating manual for the Daewoo Gasboiler gas boiler, which describes in great detail the principles of operation, methods for testing and installing equipment, as well as checking operation after installation is completed.

The “Functional part” section provides schematic diagrams of various models and indicates diagnostic points of printed circuit boards for repair. The operating principle of the electronics and its possible malfunctions are described in detail. DGB models are in demand on the Russian market - 130/160/200, in which the number 130 or 160, for example, indicates the size of the heated area.

Heating boilers from DAESUNG CELTIC

The Celtic double-circuit gas boiler, produced by a South Korean company, is adapted for Russian conditions - an unstable electrical network and pressure drops in gas mains.

With the help of DAESUNG CELTIC boilers you can heat an individual house with an area of ​​120 to 350 square meters. m.

CELTIC DS gas boilers are equipped with electronics that allow remote control using a GSM/GPRS modem.

Gas boilers from KITURAMI

Boilers of the largest South Korean gas equipment are the standard of the highest quality and reliability. KITURAMI products have been known for over 50 years. It produces high-tech equipment, which is ensured by the presence of a powerful research and production base.

The Kiturami double-circuit gas boiler has international certificates and is adapted for Russian latitudes. For reliable operation of electronics, special measures have been taken to minimize the impact of voltage surges on equipment operation. The boiler is equipped with a unique automatic system to prevent water from freezing in the pipelines. Each kiturami gas boiler is completed and assembled at Japanese and Korean enterprises by experienced specialists, which ensures excellent quality of the products.

Controlling the operation of the boiler is extremely simple, you only need to set the desired temperature level, everything else will be done automatically. The owners who purchased and installed a Kiturami gas boiler leave different reviews that were found online. Convenient and simple control; many people like the system for supplying hot water to their home (DHW). Some users note the efficiency of the boiler.

It should be noted that KITURAMI produces wall-mounted and floor-standing gas boilers. The model range includes several dozen modifications. Naturally, Kiturami gas boilers have different prices, depending on the power and model, but their cost is always lower than similar European models. Wall-mounted models are especially popular - the Kiturami World Plus mounted boiler, the Kiturami World 5000 boiler and the Kiturami ECO Condensing condensing boilers. Kiturami gas boilers are actively discussed on forums on the Internet; reviews from owners confirm their high quality, convenient operation and reliability.

Gas boilers from KOREASTAR

In the production of gas boilers, the company uses not only Korean and Japanese components, but also equipment from well-known European companies. For example, Korea Star gas boilers are equipped with Wilo circulation pumps with a wet rotor, which ensures silent operation. The most popular gas boiler is Korea Star, known as Koreastar Premium.

The Koreastar Premium gas boiler is a classic design with two heat exchangers, a Wilo circulation pump and a closed combustion chamber. The device is adapted for Russian operating conditions and reliably heats an area of ​​up to 240 m2.

The Koreastar ACE boiler is equipped with a double-circuit copper heat exchanger (pipe in pipe) with an anti-corrosion coating that is resistant to temperature changes. The combustion chamber is closed with an inflatable modulating burner. The boiler has an anti-freeze system, anti-blocking of the pump and gas valve and protection against water hammer. Power up to 32 kW.

The popularity of Corestar equipment can be judged by the exchange of information on Internet forums. Reviews of Korea Star gas boilers indicate that they are productive and reliable equipment, and the disadvantages are almost the same for any appliance with closed combustion chambers.

Koreastar boilers have a display and self-diagnosis system.

The instructions for the gas boiler Korea Star classify, describe and suggest measures to eliminate them, which appear on the display in the form of a specific code.

Boilers of the Korean concern NAVIEN

The NAVIEN company, one of the leading South Korean companies producing gas equipment, sells atmospheric, turbocharged and condensing wall-mounted gas boilers on the Russian market.

The first series is represented by a boiler with an open combustion chamber Navien Atmo. It is fully adapted to the difficult operating conditions in Russia. The series includes 4 models with powers of 13, 16, 20, 24 kW. All models have a hot water system. The reviews for these Korean Navien gas boilers were initially quite bad, but the company took certain measures and improved the quality of the devices.

The second line – three series of models:

1. Deluxe - consists of 7 models with power from 13 - 40 kW;
2. Prime - includes 6 models with powers from 13 - 35 kW;
3. Smart TOK - presented in 6 models from 13 - 35 kW.

The most expensive Korean gas boilers are Navien, the price of which, due to the highest efficiency and more complex design, is higher than that of other models - condensing boilers. They are represented by the NCN series of 4 models with powers from 21 - 40 kW and NCB, which are implemented in four models, their power 24 - 40 kW.

Manufacturers

There are indeed a significant number of Korean-made gas heating boilers on the market.

The best manufacturers are:

• Daewoo.
• Navien.
• Kiturami.
• Olympia.

Let's take a closer look at these manufacturers.

A feature of boilers from Korea is automation

Daewoo heating boilers are presented on the Russian market in two very similar lines - DGB MSC and DGB MCF. They are very similar in design and characteristics.

The main difference is the type of burners. The DGB MSC has turbocharged burners, while the DGB MCF has atmospheric burners. Representatives of both one and the second line are distinguished by ease of installation and operation, the presence of a convenient screen with indicators and a remote control. The characteristics of the boilers are also similar: efficiency is 91%, power - 11-46 kW.

Gas heating boilers presented by Navien are the most popular today. There are several reasons for this. First of all, these are several high-quality lines, among which Ace boilers are especially popular.

The line includes single- and double-circuit models, with closed and open combustion chambers. Navien boilers stand out among their analogues due to their excellent characteristics, high-quality automation, programming capabilities, long service life and the ability to operate without failures even with a significant pressure drop in the gas supply system.

Kiturami are high-quality modern gas boilers equipped with a significant number of sensors. This factor makes using the products of this manufacturer as safe and simple as possible. Several lines represent both wall-mounted and floor-standing single- and double-circuit boilers. Good characteristics, affordable cost and long service life make this equipment very popular and in demand.

We wrote in more detail about the manufacturer Kiturami here: https://kvarremontnik.ru/dizelnyjj-kotel-otopleniya-kiturami/

Olympia boilers are presented on the market with a wide range of equipment for heating and hot water systems. Distinctive features are efficiency, ease of operation and a multifunctional automatic unit that allows you to program the operation of the system.

Advantages and disadvantages

Korean wall-mounted gas heating boilers are very popular today for a number of reasons.

The advantages of equipment from Asian manufacturers include the following parameters:

• Affordable cost - Korean boilers are significantly cheaper than their European counterparts.
• Reliability – the equipment operates even with significant pressure fluctuations in the gas supply system.
• A significant number of sensors - some manufacturers install up to 10-15 different sensors in boilers, which help make the device safer. It is noteworthy that when purchasing boilers of European or domestic production, these sensors can be installed only on an individual basis - they are not included in the package.
• Environmental friendliness - unlike Russian manufacturers, Korean manufacturers try to do everything possible to ensure that their equipment causes as little harm to the environment as possible.
• Attractiveness – Korean boilers can be called one of the most beautiful. They are distinguished by an attractive stylish design and a wide range of colors. Some models are decorated with beautiful designs.

However, any equipment has not only advantages, but also disadvantages. And Korean-made gas heating boilers are no exception. But, in fairness, it should be noted that such boilers have only one significant drawback - the complexity of the need for service and repair. There are few certified service centers of Korean manufacturers in Russia, so some difficulties with service may arise.

In addition, if there is a need to replace components, it may take considerable time to find an analogue.

A little history and examples of boilers from Daewoo in the video below. We recommend giving him a couple of minutes of your time.

Korean manufacturers

Korean manufacturers such as Kiturami, Navien, Daewoo have long gained popularity in the domestic market. They offer the consumer a fairly wide range of products that are durable and reliable.

For those looking for high-quality heating equipment, you should pay attention to the following brands from Korea:

1. Kiturami. This manufacturer is a worthy competitor for European companies. The functionality of these boilers is in no way inferior to the French and Italians, and in terms of reliability - to the Germans and Czechs. One of the main advantages of Kiturami boilers is a very accessible interface, thanks to which everyone, even pensioners, can use such equipment.
2. Navien. This manufacturer has the most numerous lines. These boilers are designed for conditions where there is no stable voltage. That is why they are so often installed in holiday villages, where there are not only problems with voltage, but also with pressure in the gas and water supply systems. The manufacturer coats the inside of the heat exchangers with a special anti-corrosion solution, which significantly extends the service life of the units. In general, all Navien boilers have similar performance characteristics, except for power.
3. Daewoo. One of the distinctive features of this company is its compactness. Therefore, these boilers are convenient to install not only in houses, but also in apartments. There are models that can cope with an area of ​​up to 400 sq.m. These boilers can be used as main or auxiliary heat generators. To increase efficiency and reduce fuel consumption, the devices are equipped with a gas supply modulator and an electronic timer. All devices are adapted to work with natural and condensed gas.

All these companies occupy approximately the same position in the ranking of popularity and reliability. But also, all their equipment has a slight difference in price - from 350 to 420 dollars.

Korean gas boilers

Korean gas boilers presented on the Russian market are distinguished by a wide variety of brands and models. Among them are many Korean gas boilers made under Japanese licenses, and appliances from world-famous multi-industry brands of South Korea, such as Daewoo or Hyundai, and products from Korean companies specializing in the development and production of gas boilers.

Wall-mounted Korean heating boilers manufactured using Japanese technology

Korean gas heating boilers produced under Japanese brands are not inferior in quality and technical level to goods manufactured in Japan. Products are manufactured in South Korea using original technologies and under the careful supervision of brand owners.

Among the Korean heating boilers produced using Japanese technologies, the most famous are the boilers produced under the Rinnai brand. Korean wall-mounted boilers of this brand are equipped with the latest technology, but their price, unlike gas boilers produced in Japan itself, is relatively low, therefore they are able to successfully compete with the best European models of heating boilers not only in quality, but also in cost .

Korean boilers of our own design

Korean gas boilers of their own design are not much inferior to prestigious Japanese and European models. Most of these are wall-mounted double-circuit boilers designed for both heating and hot water supply to an apartment or country house. The focus on this type of gas boilers is due to the fact that in countries with high population density, such as South Korea, the issue of optimal use of living space is very relevant.

In addition, Korean gas boilers are very economical. Korea does not produce its own gas, it has to be imported, and imported gas is not cheap. Therefore, a thermal boiler that uses fuel most economically and efficiently will have a great competitive advantage in this country.

If you want to buy a good wall-mounted boiler at a relatively low price, choosing a Korean boiler will be one of the best.

Gas boiler, Korea, Daewoo and Hyundai brands

Gas heating boilers of Korean brands Navien, Kiturami, Master Gas

In addition to multidisciplinary companies in South Korea, there are companies that specialize in the production of heating boilers. Korean gas boilers Navien, Kiturami, Master Gas are not so equipped with a variety of electronics that create additional convenience for the consumer, but the gas equipment in the products of these heating boiler manufacturers is usually of a higher level of strength, durability and reliability. These boiler companies produce not only appliances for domestic use, but also industrial gas equipment, the requirements for which are much more stringent.

For example, Master Gas wall-mounted heating boilers are simple, reliable, compact and inexpensive Korean double-circuit gas boilers with a closed combustion chamber and turbocharging with a power of 11 to 35 kW. They are capable of heating a house up to 350 m² and providing it with hot water.

Korean gas heating boilers - advantages and disadvantages

Like any appliance, Korean gas heating boilers have their advantages and disadvantages. The advantages of gas Korean heating boilers include the following:

• high level of technical equipment;
• quality and reliability;
• compactness and efficiency;
• relatively low prices.

The disadvantage of gas boilers made in Korea is essentially one - the relative difficulty of finding spare parts and components if they need to be replaced during repairs. This is especially true for brands that are poorly represented on the Russian market and do not have their own service centers. Therefore, it is better to buy Korean gas boilers from official dealers and companies that directly cooperate with their manufacturers

In this case, you should pay attention not only to the price, but also to the warranty periods and conditions of warranty service

Where to buy Korean gas boilers and at what prices?

Korean ones are not cheap boilers, but their prices are significantly lower than the prices for European models of a similar level. You can see the current prices for Korean heating boilers in the catalog on our website.

The best Korean manufacturers and models: characteristics and prices

In Korea, several companies produce heating equipment. But the boilers differ not only in name. Almost every company has its own characteristics that set it apart from its competitors. Therefore, I want to talk about each of them in more detail.

Navien

One of the best and most common Korean gas boilers for heating a private home. It is also in good demand on the Russian market. The variety of models is impressive: wall-mounted and floor-mounted, single-circuit and double-circuit, atmospheric and turbocharged, convection and condensation. Gas Naviens are also known for their reliability (although there are exceptions). These are the boilers I had in mind when I talked about the availability of spare parts. They are almost always there...

I would like to debunk a couple of myths that for some reason sellers constantly talk about. Firstly, I have often come across the opinion that Navien boilers have a built-in stabilizer. This is wrong. Yes, there is protection against voltage surges. But almost all Korean boilers have the same protection. Secondly, the heat exchanger in wall-mounted boilers is not made of stainless steel. This is steel with an anti-corrosion coating. Well, in general, they are very good boilers that are worthy of attention.

Model Navien Deluxe-24k.

The most popular model is Navien Deluxe-24k - a wall-mounted double-circuit boiler with a closed combustion chamber with a power of 24 kW. Efficiency is 90.5%, and maximum gas flow is 2.58 m3/hour. The water circuit is designed for operating pressure up to 3 bar, so the boiler can be installed in almost any heating system. It can be controlled using a remote control. The only drawback is the poor quality of assembly and fastening materials, which makes the boiler quite difficult to disassemble after years of operation. Cost: 29,000-31,500 rubles .

Model Navien GA 23KN.

Among the floor-standing models, it is worth noting the well-known Navien GA 23KN - this boiler is also a double-circuit boiler. The advantage is the large diameter of the pipes and a massive, more durable heat exchanger that will not clog even when installed on an old metal heating system. Cost: 36,900-39,000 rubles .

Kiturami

The company has been producing heating equipment for a long time. The line also includes a large selection of models: floor and wall, convection and condensation. A characteristic difference is the presence of advanced, but at the same time easy-to-control automation. Many models are equipped with a remote control, and most importantly, a programmer that allows you to set the boiler operating mode for a day or a week and significantly reduce gas consumption at night or when the owners are away from home. They are similar in efficiency and reliability to Navien. At the same time, wall-mounted models still belong to the budget price segment (up to 30-33 thousand rubles).

Model Kiturami TWIN ALPHA-20.

The most successful wall-mounted model is the Kiturami TWIN ALPHA-20 - the device of this model is distinguished by a special low-noise fan, and the ignition is relatively quiet. There is a remote control and a programmer. Otherwise, the model does not stand out in any way; it has a standard device, like more than 70% of gas mounted boilers. The only drawback is the lack of a “Summer” mode. Cost: 29,000-31,000 rubles .

Kiturami floor-standing models are considered not entirely successful and practical, since having a not-so-budget price, they are designed in a very simple way.

The most common example is Kiturami TGB-30R - a double-circuit boiler with a thermal power of 35 kW. The heat exchanger is steel, there is no programmer, although there is a room thermostat, noisy operation. However, regarding reliability: for more than 10 years of operation there are practically no serious service complaints. Cost: 65,000-66,000 rubles .

How to calculate the required boiler power Individual calculation, formula and correction factors

DAEWOO

Unusual-looking boilers, more square and austere. The company produces exclusively wall-mounted equipment. They differ in power, number of circuits and method of gas removal. Condensation models are also available. Among the disadvantages, users highlight the rather noisy operation. I agree with them, but this applies more to previous generations of boilers. Now they are noticeably quieter.

One of the advantages is the adjustable power thanks to the modulating burner. If you lower it, the boiler will consume less gas. This is useful in small areas. Also, many models are equipped with a remote control, but without a programmer. A special feature is also more corrosion-resistant, heat-conducting heat exchangers. However, in terms of cost, Daewoo boilers can hardly be classified as budget ones, which is definitely a disadvantage.

Model Daewoo DGB160MSC.

The most famous wall-mounted boiler is Daewoo DGB160MSC - a standard convection boiler with a closed combustion chamber. Control using a remote control. Has two separate heat exchangers. The main one is made of copper. Disadvantages: price, noise and high requirements for installation quality. Cost: 33-42 thousand rubles . There is also a condensing option - Daewoo DGB160MES, but it is even more expensive, in domestic conditions it hardly pays for itself, and it is extremely difficult to find it on sale today.

KoreaStar

These boilers are distinguished by the fact that they are equipped with not only Korean spare parts, but also European ones. The company itself talks about the use of silent circulation pumps. This is true. But the noise is usually created not by the pump, but by the fan, which is installed in turbocharged models to remove combustion products. Therefore, such an advantage is doubtful.

But the double protection of the heat exchanger from overheating is worthy of attention. This method significantly extends the service life. KoreaStar produces floor-mounted and wall-mounted models, as well as turbocharged and naturally aspirated ones. But they don’t have condensing boilers in their lineup.

The only problem is that today in Russia the choice is limited to only a few floor-standing models; wall-mounted ones are almost impossible to find even in warehouses. The service structure is also not very developed. The most successful floor-standing model is KoreaStar Buran 10 - the simplest floor-standing atmospheric single-circuit boiler with a steel heat exchanger with a capacity of 10 kW.

Model KoreaStar Buran 10.

Does not require connection to the electrical network, designed for operating pressure up to 3 bar. The cost is only 19,000-22,000 rubles .

Olympia

The company mainly offers diesel heating equipment. But gas models are also present. Particular attention is paid to the quality of the gas burner. Not bad boilers, but not particularly represented on the Russian market. If you are planning to buy equipment from this company, be sure to check the availability of spare parts and the possibility of service.

Wall-mounted models are relatively inexpensive. But floor-standing ones can cost 50,000 rubles.

• Olympia OLB 200 WGR - wall-mounted and dual-circuit, power 20 kW. To be honest, it looks a little like Daewoo, but I don’t like the design.
• Olympia OLB 250 GR - this double-circuit floor-standing boiler has a power of 25 kW. The main heat exchanger is made of steel.

How to clean a gas boiler and extend its service life: detailed instructions

Why is a Korean boiler cheaper than a European one?

Actually this is not always the case. I have come across expensive Korean boilers, the prices of which were even higher than the top European models. I will not disclose the name of the manufacturer so as not to give him free advertising.

However, in general, Korean boilers cost less than their European counterparts and this is due to two factors:

• Cheaper labor
• Saving on components.

Cheaper labor does not mean that Korean pots are assembled by illiterate peasants for a cup of rice a day. It’s just that people in Korea earn less, but still have the necessary qualifications (at least from large firms). But with the quality of components the issue is more complicated. It's no secret that high-quality materials are expensive, and if you want to save money, you have to look for a replacement. For example, expensive copper heat exchangers are being replaced by cheaper ones made of stainless steel (we are talking about plate heat exchangers). The same applies to brass parts, which are replaced by polymer ones. I myself saw a Korean boiler in which the heat exchanger is connected to the circulation pump using a rubber hose, and the hose itself is tightened onto the pipe with a regular car clamp. All this raises questions about the reliability of the equipment.

Another interesting point - all (that I saw) Korean boilers were double-circuit.

Now let's move on to considering individual components on Korean and European boilers.

Model range of Kiturami gas boilers

The heating systems of this Korean company can easily compete with well-known European brands. With their functionality they can easily compete with Italian and French manufacturers, and with their reliability and quality - with Czech and German ones.

The line of wall-mounted dual-circuit equipment includes the following models:

1. Kiturami Twin Alpha is a gas device with heat exchangers made of copper and aluminum. It has a forced air injection system and removal of combustion products. You can precisely set the settings for boiler operation using several mode options. The design is equipped with a protection system against overheating of the coolant and against gas entering the room.
2. Kiturami World Plus - the equipment was specially adapted for Russian working conditions. This model was the first to be equipped with a proprietary gas burner with internal combustion, which ensures complete combustion of fuel and, as a result, saves gas. The devices of this model include a remote thermostat. The gas boiler is equipped with a controller, with which the room heating mode can be programmed to suit individual needs.
3. KituramiWorld 3000 - double-circuit designs with copper heat exchangers and a coaxial chimney. After purchasing nozzles, the device can be converted to operate on liquefied gas.
4. Kiturami World 5000 - gas heating systems with which you can heat a room with an area of ​​up to 350 square meters. m. The device is able to automatically maintain an optimal climate even after a sharp drop in temperature. The built-in circular pump will prevent the system from freezing. The control unit is equipped with a gas leakage protection system. In the event of a sharp decrease in gas pressure, overheating of the heat exchanger, or a power outage, the equipment safety system automatically stops the gas supply.

The main rule of the manufacturer of gas boilers in this line is strict consideration of build quality and ensuring easy installation of the system and its simple operation.

Navien

This South Korean company is one of the leading ones at present, and boilers from this manufacturer are in great demand among Russian owners of private houses. Reviews for Korean Navien gas boilers were initially quite bad, but the company took certain measures and improved the quality of its devices.

Initially, Navien supplied only air conditioners and convectors to the Russian market. Russian citizens became acquainted with heating equipment in 2007.

The model range is represented by double-circuit gas and diesel boilers in wall-mounted and floor-mounted versions.

Gas condensing boiler Navien NCN

Heat exchangers for Korean and European boilers.

As mentioned above, many Korean manufacturers use cheaper stainless steel plate heat exchangers. Such heat exchangers have thinner walls than their copper counterparts. Thin walls shorten the life of this expensive unit. I know of cases where Korean heat exchangers failed even before the end of the warranty period, and this was due to the use of an “anti-freeze” based on ethylene glycol or propylene glycol as a coolant. The fact is that such liquids dissipate heat worse than ordinary water. Therefore, the walls of the heat exchanger begin to overheat and eventually burn out faster. In addition, there were cases when, due to overheating of such a coolant, precipitation fell inside the heat exchanger, which also led to its failure. Because of all these troubles, warranty centers strictly prohibit the use of such coolant in their boilers.

As for the “Europeans,” they are more tolerant of the use of such liquids, but they give strict instructions regarding the chemical composition and concentration of coolants. In case the user violates their recommendations. They refuse to do warranty repairs

Product characteristics

NAVIEN products have been represented on the domestic market of equipment for autonomous heating for several years now. Boilers of this brand are characterized by reliability, versatility, high level of automation and impeccable workmanship. The power of manufactured units varies from 16 to 35 K.

Gas boilers are specially designed for Russian conditions, where the pressure in gas mains is not stable and sudden temperature changes occur. In our country, Korean gas heating devices can be sold under the Saturn brand.

The functionality and practicality of Navien double-circuit gas boilers is known far beyond the borders of South Korea. All equipment is ideal for providing heat to residential premises, offices or industrial buildings.

About heat exchangers

Note! The main feature that is inherent in all Navien gas boilers is the presence of two heat exchangers. They are insulated from each other, which makes it possible to maintain different temperature conditions in them. This is what makes it possible to effectively use the generated heat. It is recommended to entrust installation to professionals

It is recommended to entrust installation to professionals

In double-circuit boilers, preference is given to hot water supply. In this case, the temperature can be set manually directly for each case. When a hot water tap is opened, the device switches to heating water and remains in this mode until the tap closes.

In addition, all elements of double-circuit boilers for individual heating systems are resistant to corrosion, as they are made of stainless steel. And this additionally guarantees a long period of operation of the unit.

Another important advantage of Navien products is their relatively low cost. Therefore, such technology is available to almost all categories of the population.

Both heat exchange circuits in heating devices are resistant to contamination. They reliably resist scale formation. This ensures high performance and protects the unit from breakdowns. In addition, all units are accessible and easy to maintain.

About other control systems

The gas boiler from South Korean manufacturers is equipped with an NR-15SR thermostat. This allows consumers to independently set the optimal temperature in the room or the temperature of hot water in the DHW system.

New technologies and innovations in this area have made it possible to develop the SMPS (method of switching power supply) chip. It reliably protects the boiler from changes in the electrical network within 30% of the normal voltage of 220 V, thereby extending its service life.

Range of boilers

The device has a sensor that regulates air pressure (APS). His job is to control the supply of the required amount of its complete combustion. Therefore, combustion of the gas mixture occurs stably, thereby reducing its consumption.

Navien heating devices are designed for uninterrupted and efficient operation even under conditions of reduced gas pressure - 4 bar.

When the temperature drops below +5 degrees, the boiler turns on the antifreeze system, as a result of which the circulation pump automatically starts. With constant movement of water in the pipes, freezing is impossible.

A gas boiler made in South Korea can operate fully even with low inlet water pressure in the system, which usually affects multi-storey buildings.

About turbocharging

Each double-circuit boiler from the best Korean manufacturers is equipped with a special device in the form of fans that provide air under pressure.

Thanks to this development by Korean specialists, the gas combustion coefficient is quite high, which has a beneficial effect on efficiency. Air supply is controlled thanks to automatic systems equipped with pressure sensors.

About balancing the working mixture

Smoke exhaust pipe

The company's specialists pay great attention to the design of new models, as well as control of all production processes. The tandem of these components answers the question why gas double-circuit units of the NAVIEN brand have such impeccable quality

A professional approach to the development of each detail, taking into account the most insignificant subtleties, made it possible to achieve the supply of a well-balanced working mixture to the combustion chamber.

TOP 5 energy-independent gas boilers

Non-volatile boilers are a good choice for working in remote villages or regions with overloaded and dilapidated electrical networks. They continue to work in the event of a sudden power outage and do not require high costs for repairs or replacement of failed components. Let's look at the most popular models:

Prices: summary comparison table

It is difficult to say which Korean boiler is better. But the choice is quite large. First you need to decide on the installation method. Then choose between an open and closed combustion chamber. If you are planning to install a boiler, you should take a closer look at single-circuit models. If there is no separate water heater, a double-circuit boiler will do. And after that you need to determine the power, brand and model.

Korean boilers have long proven themselves on the Russian market. They are simple and inexpensive to maintain. Knowing their cost, you need to be objective about quality and durability; you don’t need to worry if some kind of malfunction is discovered. Everything breaks down, including the most expensive equipment. You don't throw away your car if it breaks down. It's the same with the boiler. If it is installed correctly and maintained on time, it will work for many years without causing problems.

Installation

Before installing the device, you should make sure that it runs on natural gas. If you plan to use liquefied gas, you need to readjust the heater - this should be done by a specialist. A power supply with parameters of 220 V/50 Hz must be supplied to the installation site of volatile models. Deviation of parameters from the norm leads to decreased performance and reduced service life.

It is prohibited to connect other electrical appliances to the boiler power source. It is also prohibited to use extension cords and adapters when connecting. Violation of safety standards may result in a fire.

Features of operation

KoreaStar boilers, being productive and reliable, have advantages and disadvantages characteristic of any equipment with a closed firebox:

• Noisy. The reason is the operation of the fans. With their help, air is pumped and removed from the coaxial chimney. A distinctive feature of all forced-air burners is noisy operation. It is advisable to install such heaters away from living rooms.
• The water in the hot water supply is heated separately from the coolant. A three-way solenoid valve increases the heating speed and ensures a uniform supply of water at any pressure in the water pipes.
• When the coolant cools down to +5 °C, the boiler automatically starts, preventing defrosting of the heating system.
• Energy dependence. The instructions for use of KoreaStar heaters say that they are capable of operating under voltage surges of up to 15% of the nominal value. But in practice there are problems, the controller board fails. Installing an uninterruptible power supply will help prevent breakdowns.
• Before connecting the device, you need to obtain permission and order design documentation from the gas service.

Korean heating systems - pros and cons

Korean technology is improving more and more and is no longer much different from its European counterparts. At the same time, it has good quality and fairly reasonable prices, which is increasingly attracting buyers.

Advantages of gas boilers made in Korea:

1. Versatility. Wall-mounted systems can be used for heating any objects and, without purchasing additional equipment, can operate on both natural and liquefied gas.
2. Uninterrupted operation. Even in conditions of unstable pressure in the gas pipeline, the structures will operate without failure.
3. High degree of security. Wall-mounted boilers are equipped with twelve sensors for protection against all kinds of malfunctions.
4. High efficiency.
5. Modern design and compactness.
6. Wide range of models.
7. Reasonable price.

Some samples of gas devices are equipped with a corrosion-resistant and durable heat exchanger.

The disadvantages of Korean heating systems include the difficulty of selecting spare parts that may be needed after a breakdown of the structure. In European-made boilers, parts can be replaced with components from other manufacturers. When repairing Korean devices, you will need to look for spare parts only made in Korea. Therefore, before purchasing such a boiler, it is recommended to find out whether there are service centers in the city for servicing this type of heating device.

Daewoo – compact gas equipment

Double-circuit wall-mounted boilers from this manufacturer are distinguished by their reasonable price, compactness, programmable operating mode and an expanded list of built-in protections. In addition to these advantages, Daewoo gas boilers have many other advantages:

1. They can be used for heating rooms with an area of ​​up to 400 square meters. m.
2. The boilers can be connected to a powerful heating system.
3. The devices are small in size, so they easily fit in almost any room.
4. The units have simple controls that even a child can handle.
5. Using a gas supply modulator and an electronic timer, which is equipped with a double-circuit boiler, you can significantly reduce fuel consumption and increase efficiency.
6. Wall-mounted appliances can operate on natural and liquefied gas.
7. Using a patented device, the supply of coolant in the hot water supply and heating system is uninterrupted.
8. Daewoo designs are equipped with a switching power supply, which effectively protects the system from breakdowns in the event of sudden voltage changes.

If necessary, the equipment can be equipped with a remote control. With its help, you can control the operation of the device at a distance of up to fifty meters.

Hydraulic group and circulation pump.

Now let's talk about such an important boiler unit as the hydraulic group. A hydraulic group is two units (input and output), between which a jumper (bypass) is installed, which is necessary to ensure circulation in the heating system

A three-way valve can be installed at the outlet node to connect an external indirect heating boiler.

The hydraulic group can be made of brass or polymer materials. In the latter case, its cost is significantly reduced due to simpler manufacturing technology. But the question of the reliability of such materials remains open. My personal opinion is that brass is a more reliable and proven material for such important components as a hydraulic group.

As for Korean or European boilers, they have both brass and polymer groups. It all depends on the price category of the boiler. More expensive models have brass, while cheaper ones have plastic.

As for circulation pumps, European boilers use pumps from well-known companies, while for Korean boilers the pumps are made either in Korea itself or in China. This may not affect the quality in any way. Here everything again depends on the price category of the equipment.

A little about the benefits

To understand what exactly is characteristic of Korean heating boilers, it is important to study in more detail the main advantages inherent in these units. Among the main advantages we note:

• Low cost with decent performance characteristics.
• Versatility, which allows them to be used for heating homes and industrial and administrative facilities.
• Safe operation, which is characteristic of almost all Korean boilers. Many wall-mounted heaters are equipped with special protection sensors as standard. In this regard, Korean gas boilers are much more attractive compared to European ones, since in the latter many security systems are an additional option for which you have to pay.
• Compact and minimalist design. The equipment does not take up much space in the bathroom, bathroom or utility room.
• High efficiency. This parameter is very important for every consumer. And Korean engineers manage to achieve incredible results in terms of the performance of their products.
• High reliability of the design. Many models, such as Korean Navien boilers, are equipped with a tubular heat exchanger, which is characterized by increased strength and resistance to rust. For equipment that is operated in conditions of low quality coolant, this is a real salvation.
