Advantages and disadvantages
A large number of advantages that are inherent in Korean-made boilers can be noted:
- Versatility. For example, wall-mounted systems can be used to heat any objects and, without purchasing additional configurations, operate on both natural and liquefied gas.
- Uninterrupted work. Even under conditions of unstable pressure in the gas pipeline, the equipment will operate without fail.
- High degree of security. For example, wall-mounted boilers are equipped with twelve sensors for protection against all kinds of malfunctions.
- High efficiency.
- Wide range of models.
- Modern design.
- Low price.
- Compactness.
The disadvantage of gas boilers manufactured in South Korea is the insufficiently well-established work of service centers. In addition, it will not be easy to find spare parts for such a unit.
On the Russian market, the most famous 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.
Benefits
In addition, Korean-made units successfully combine acceptable cost with excellent performance, the ability to use it for heating industrial facilities and private houses.
Attracted by Korean gas heating boilers and the possibility of safe operation. For example, wall-mounted gas devices are equipped with 12 protection sensors, while the purchase of safety devices for installed European-made boilers is an additional cost item.
Korean wall gas heating devices are compact and reliable, high efficiency. Some samples are equipped with a tubular heat exchanger, which is more durable and corrosion resistant.
Navien
This South Korean company is one of the leading at present, and the boilers of this manufacturer are in great demand among Russian owners of private houses. At first, the reviews on the Korean Navien gas boilers were rather 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 inhabitants got acquainted with heating equipment in 2007.
The model range is represented by double-circuit gas and diesel boilers in wall and floor versions.

Why is a Korean boiler cheaper than a European one?
Actually, this is not always the case. I had to deal with 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 make him free advertising.
However, in general, Korean boilers cost less than their European counterparts and this is due to two factors:
- Cheaper labor
- Savings on components.
Cheaper labor does not mean that Korean boilers are collected by illiterate peasants for a cup of rice a day. It's just that people in Korea earn less, but at the same time 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 stainless steel heat exchangers (we are talking about plate heat exchangers). The same applies to brass parts, which are replaced with polymeric 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 on the pipe with an ordinary car clamp. All this raises questions about the reliability of the equipment.
Another interesting point is that all (which I saw) Korean boilers were double-circuit.
Now let's move on to examining individual units on Korean and European boilers.
Kiturami
The heating equipment manufactured by this Korean company is known for its high quality and reliability; it can easily compete with European manufacturers.
The Kiturami company was founded in 1962. At the moment it has more than 16 production centers in its structure.
The device of the wall-mounted gas boiler Kiturami TWIN ALPHA-25R
Wall-mounted double-circuit gas boilers are represented by the following models.
| Model | Description |
| Kiturami twin alpha | Equipped with copper and aluminum heat exchangers. It has a forced air injection and combustion products removal system. You can fine-tune the settings for the boiler operation using several mode options. Equipped with a system of protection against overheating of the coolant and against the ingress of gas into the room. |
| Kiturami world plu | This model was for the first time equipped with a proprietary internal combustion gas burner, which allows for complete combustion of fuel and, as a result, saves gas. The complete set of devices of this model includes a remote thermostat. The gas boiler is equipped with a controller, with which the room heating mode can be programmed according to individual needs. |
| Kiturami World 5000 | Gas heating systems with which you can heat a room up to 350 m². The device is able to automatically maintain the optimal climate even after a sharp drop in temperature. There is a built-in circular pump. The control unit is equipped with a gas leakage protection system. In the event of a sharp drop in gas pressure, overheating of the heat exchanger, power outage, the safety system of the equipment automatically stops the gas supply. |
Antifreeze can act as a coolant for the heating system.
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 when Korean heat exchangers broke down even before the end of the warranty period, and this was due to the use of "non-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 out inside the heat exchanger, which also leads to its failure. Because of all these troubles, warranty centers strictly forbid the use of such a coolant in their boilers.
As for the "Europeans", they are more tolerant of the use of such fluids, but when they give strict instructions about the chemical composition and concentration of coolants. If the user violates their recommendations. They refuse to do warranty repairs
Stainless steel heat exchanger Copper heat exchanger with a special protective coating.
Daewoo
Daewoo is characterized by the production of boilers with low cost, compactness, the operating mode in these devices is programmable, and besides, they are easy to operate.
Household appliances of the South Korean company DAEWOO are famous all over the world, therefore, Russian ordinary people choose a gas boiler of this brand, as a consequence of their trust in the company.

Description of gas boilers
Gas heating equipment can be used to heat rooms of various sizes. Compared to electric boilers and those that run on solid fuels, gas boilers have some advantages:
- The performance characteristics are high.
- Gas prices are affordable for most consumers.
- There is no need to set aside storage space for fuel, as is the case with coal or wood.
- There is no need to clean the ash pan and control the draft.
Gas boilers are divided into two types: wall-mounted and floor-standing. Wall-mounted gas heating boilers can be used to heat rooms, the area of which does not exceed square meters, or city apartments. Floor standing equipment is used to heat larger objects.
In order to choose the best option for a gas boiler and avoid unpleasant moments during operation, it is important to find out what types of boilers exist, their characteristics and features, and also to study well-known brands of gas equipment and their cost.
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 gas burner made of stainless steel, 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 temperature of the coolant, a digital data processor. |
Prices: Summary Comparison Chart
It is difficult to say which Korean cauldron is better. But the choice is large enough. First you need to decide on the installation method. Then choose between an open and a closed combustion chamber.If you are planning to install a boiler, it is worth taking 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, firm and model.

Selection of gas heating boilers
When deciding which hinged gas boiler to choose, the following factors must be taken into account:
- Hot water needs. It is necessary to calculate how much water is needed for the people living in the apartment, and also to determine whether several hot water supply points will turn on at the same time.
- The volume and power of the boiler, these indicators are determined by the size of the heated area.
- The type of heating system (the heating medium circulates forcibly or naturally).
- Estimated costs, namely, what funds are planned to be spent on the purchase of a gas boiler.
- The degree of comfort, based on this factor, is determined by the control system of the equipment.
- Manufacturer. It is possible that all other factors do not matter if the choice is made in favor of a particular brand.
In addition, it is worth considering that the power supply system can operate intermittently, which leads to additional costs for voltage stabilizers for delicate European equipment (for more details: "Which voltage stabilizer is better for a gas boiler - types, differences, selection rules for the heating system"). The hardness of water in hot and cold water supply systems also adversely affects the operation of some devices, so this factor should also be taken into account.
How to choose a boiler from a good manufacturer
When choosing a double-circuit boiler, you should pay attention not only to the quality and the manufacturer and its reputation, but also to whether the device is suitable for operation in Russian conditions. Very often foreign gas boilers are quite sensitive to the heat carrier used and its quality. Electronics breaks down on power surges.
One of the important points when choosing a device is the availability of its maintenance after installation, because in winter at negative temperatures, a delay in the event of a malfunction can end fatally for the heating system. The situation is also unacceptable when, if you need to replace any element of the boiler, you have to travel to a neighboring region or even a country.

Heat exchangers
Depending on the material of manufacture, one or another property of the heat exchanger is determined, which is very important when solving the problem of how to choose a double-circuit gas boiler. Copper products are characterized by high thermal conductivity, and stainless steel products serve for a long time. Bithermal heat exchangers are compact, but their service life is very short. When buying a boiler, it should be borne in mind that heat exchangers very often require replacement. Therefore, it is better to give preference to well-known brands, since repair kits and parts of popular brands are much easier to find.
