On the Russian heating equipment market, among others, South Korean companies are actively promoting their products.
They do this quite successfully - the demand for this equipment is quite high.
Let's see why Korean gas boilers are so attractive to domestic consumers and which brands should be preferred.
Advantages and disadvantages
We can note a large number of advantages that are inherent in Korean-made boilers:
- Versatility. For example, wall-mounted systems can be used to heat any facility and run on both natural and liquefied gas without purchasing additional components.
- Uninterrupted operation. Even in conditions of unstable pressure in the gas pipeline, the equipment will operate without failure.
- High degree of security. For example, wall-mounted boilers are equipped with twelve sensors for protection against all kinds of malfunctions.
- High efficiency.
- Wide selection of models.
- Modern design.
- Low price.
- Compactness.
The disadvantage of gas boilers produced in South Korea is the insufficiently well-established work of service centers. In addition, finding spare parts for such a unit will not be easy.
The most famous on the Russian market are such Korean manufacturers of heating boilers as Kiturami, Navien, Daewoo, Olympia and others.
Let's get acquainted and consider in detail each of them.
Which manufacturer is better?
Having examined the products of the two largest South Korean manufacturers of heating boilers, we can draw a general conclusion about their characteristics. Judging by the fact that most models, both from Daewoo and Navien, are distinguished by the presence of a closed combustion chamber in them, we can conclude that Korean manufacturers of gas boilers rely on the higher performance of their products and ease of installation and operation. The differences between them are in other technical parameters: maximum power (more powerful boilers are produced by Navien), the size of the heated area and the diameter of the chimney.
So which manufacturer should you prefer? Buyers are free to answer this question themselves. Almost eight dozen units with a variety of characteristics are offered to their attention, from which everyone can choose a model that suits their needs. It can be noted that it will be much easier to find the right boiler among the products of the Navien company, since the range of its products is many times more extensive than the list of products manufactured by the Navien brand. However, in terms of quality and technical characteristics, the products of these companies do not cause any complaints, so they can be safely recommended for purchase.

Reviews
Valery Garengov, 37 years old, Samara
5 years ago we bought an apartment (52 sq.m.), where a Korean boiler was already installed. On the one hand, we were very pleased, because it turned out that we did not have to spend money on such equipment. But on the first night, when my husband came home after work and my child and I were already asleep, it turned out that the device was quite loud. The boiler is just hanging on the wall in the toilet, but now we are planning to make a cabinet for it. Maybe this will help reduce the noise. And the alloy boiler is excellent - it heats the water quickly and provides sufficient heating for a two-room apartment (the radiators are made of aluminum). Every fall we call the technicians for a preventive inspection and commissioning, and we have never had a problem with this boiler.
Anastasia Varenkova, 32 years old, Ufa
But I was not satisfied with the Korean acquisition. I picked up a sample from economy class, so I was immediately attracted to Korean products. My house is 45 sq.m., so there was no point in purchasing a powerful device. As a result, I took Navien. The first season went without problems, which I was very happy about. For the second season I decided to change the coolant - switch from liquid to antifreeze. I called the technicians for this, and then started up the equipment. Literally after a month of work, problems began - the heat regenerator leaked, some kind of circuit board burned out. I won’t talk about how much I spent on repairs. But recent experts have clarified that Korean boilers are not suitable for working with antifreeze, only with water. Now I’m thinking, what’s cheaper - change the coolant category again or buy a new boiler, a boiler that can work with antifreeze?
Mark Gnyashchenko, 49 years old, Tyumen
I bought a Navien Ace-16k last year. Among the advantages, I would like to immediately note the presence of a remote control, which provides ease of use. But there is a decent amount of noise here, and the cord at the remote control is somewhat short. Although for us this is not so important. But for a house of 80 sq.m. its power is enough. Since the boiler is connected to a central gas main, I know what problems there are with pressure. The previous unit often failed for this reason. And this boiler is capable of operating not only at a reduced value, but also has protection against gas pressure changes. Now I’m thinking of moving it to the basement, making a boiler room out of it.
Kiturami
The heating equipment produced by this Korean company is known for its high quality and reliability, and can easily compete with European manufacturers.
The Kiturami company was founded in 1962. Currently it has more than 16 production centers.

Let's take a closer look at Korean gas heating boilers
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.
Daewoo
Daewoo is characterized by the production of boilers with low cost, compactness, the operating mode in these devices is programmable, and they are also easy to operate.
Household appliances from the South Korean company DAEWOO are famous all over the world, so Russian consumers choose a gas boiler of this brand as a result of their trust in the company.

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

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.
Olympia
Boilers operating on gas and liquid fuel are produced under the Olympia brand.
The Olympia concern began to conquer the domestic market since 1995. Diesel boilers have been on sale since the beginning of 2000.
| Models | Description |
| Olympia OLB | Devices with a closed combustion chamber. Power range from 15 to 700 kW. Equipped with a copper heat exchanger, a stainless steel gas burner, a three-speed circulation pump, electric ignition, a dry running sensor at the cold water inlet, a remote programmable thermostat with which you can regulate the coolant temperature, and a digital data processor. |
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.

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.
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.
