Wall-mounted gas double-circuit boilers made in South Korea: advantages, shortcomings, review of models

September 7, 2020

To date, gas heating equipment is presented on the market with a wide variety of models of boilers from manufacturers in different countries. Wall-mounted double-circuit gas systems are very popular, having in the complete set not only a torch, heat exchanger and control device, but also an extended tank, circular pumps, thermometer, pressure gauge.

Recently, more and more consumers are attracted to boilers from Korean manufacturers. Such systems are versatile, advanced basic equipment and reasonable price.

Korean heating systems - pros and cons

Korean technology is improving and differs little from its European counterparts. At the same time it has good quality and fairly reasonable prices, than attracts more and more buyers.

Dignity gas boilers, made in Korea:

  1. Versatility. Wall systems can be used for heating of any objects and without acquisition of additional complete sets to work as on natural, and on liquefied gas.

  2. Uninterrupted work. Even in conditions of unstable pressure in the gas pipeline, the structures will work flawlessly.
  3. High degree of security. Wall-mounted boilers are equipped with twelve sensors to protect 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 appliances are equipped with corrosion-resistant and strong heat exchanger.

To shortcomings Korean systems heating can be attributed to the complexity of the selection of spare parts, which may be required after the breakdown of the structure. In boilers of European production, parts can be replaced by components from other manufacturers. When repairing Korean devices, you will need to look for spare parts only made in Korea. Therefore, before buying such a boiler, recommended to find out, whether there are service centers of this type of heating device in the city.

Review of Korean gas double-circuit boilers

The most well-known Korean heating systems in the Russian market are Kiturami, Navien, Daewoo, Olympia, Korea Star.

Model range of Kiturami gas boilers

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 reliability and quality - Czech and German.

The following models are presented in the line of wall double-circuit equipment:

  1. Kiturami Twin Alpha - gas device with heat exchangers made of copper and aluminum. It has a forced system of air injection and removal of combustion products. You can precisely set the parameters of the boiler with several mode options. The design is equipped with a system of protection 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 first equipped with a branded gas burner with internal combustion, which allows for complete combustion of fuel and as a consequence, save gas. The device of this model includes a remote thermostat. The gas boiler is equipped with a controller, by means of which the mode of heating of the room can be programmed under individual needs.

  3. Kiturami World 3000 - double-circuit constructions with copper heat exchangers and coaxial chimney. After purchasing the injectors, the device can be converted to run on liquefied gas.

  4. Kiturami World 5000 - gas heating systems, with which you can heat a room with an area up to 350 sq. m. The device is able to automatically maintain an optimal climate even after a sharp drop in temperature. The built-in circular pump prevents system freezing. The control unit is equipped with a gas leakage protection system. In the case of a sharp decrease in gas pressure, overheating of the heat exchanger, power outage The safety system of the equipment automatically stops the gas supply.

The main rule of the manufacturer of gas boilers of this line is strict accounting for the quality of assembly and ensuring easy installation of the system and its simple operation.

Navien - Korea's leading manufacturers of energy equipment

Navien gas heaters are in great demand among consumers, in need of heating country houses. The equipment differs in reliability in the conditions of voltage difference in the power supply network and the lowered pressure of gas and water..

Navien Ace.

Gas units of this line have many advantages over European models:

  1. Steel heat exchangers with anti-corrosion coating make boilers quite cheap and at the same time durable.
  2. The device has a control system for the operation of the gas burner, with which the device power 13 kW is able to heat the same amount of water, as a unit with power 24 kw.
  3. Navien heating systems are equipped with the liquid crystal display and remote control with the remote sensor.

Buyers are attracted by the relatively low price of the equipment, its functionality and long service life.

Navien NCN.

It is energy intensive, economical and environmentally friendly condensing heating wall double-circuit structures, created by advanced Korean and Japanese technologies.

Advantages of Navien boilers NCN:

  • Efficiency reaches 98%;
  • can run on natural and liquefied gas;
  • have a weather-dependent mode of operation;
  • equipped with a programmable remote control;
  • the control panel of the device is equipped with the liquid crystal display with illumination of the screen;
  • the security of the system is monitored by an electronic controller, which displays information and has a digital analysis system;
  • equipped with pre-mixed burners;
  • the flue gas temperature is lower, than conventional gas boilers.

With efficient and safe Navien NCN gas units, utility bills can be significantly reduced.

Daewoo - compact gas equipment

Double-circuit wall-mounted boilers from this manufacturer are moderately priced, compactness, programmable mode and extended list of built-in protections. In addition to these benefits, Daewoo gas boilers have many other benefits:

  1. They can be used for space heating up to 400 sq. m.
  2. Boilers can be connected to a powerful heating system.
  3. The devices are small, therefore easily fit into almost any room.
  4. The units are easy to operate, which even a child can handle.
  5. With gas supply modulator and electronic timer, which is equipped with a double-circuit boiler, you can significantly reduce fuel consumption and increase efficiency.
  6. Wall-mounted appliances can run on natural and liquefied gas.
  7. With the help of the company's patented "ball-switch" technology, the devices continuously betray the supply of coolant in the hot water supply and heating system..
  8. Daewoo designs are equipped with a switching power supply, which effectively protects the system from breakdowns in the event of sudden voltage drops.

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

Olympia - wall-mounted boilers with built-in instantaneous heat exchanger

Technical solutions and innovative technologies distinguish these wall-mounted dual-circuit devices in safety and reliability. Olympia gas constructions are equipped:

  1. Copper thermal heat exchanger.
  2. Closed combustion chamber.
  3. Gas burner, made of stainless steel.
  4. Circulating three-speed pump.
  5. Variable speed fan.
  6. Controller of equipment operation.
  7. Extended membrane tank for eight liters.
  8. Electric ignition.
  9. Dry running sensor at the cold water inlet.
  10. Wine programmed thermostat, with which you can adjust the temperature of the coolant.
  11. Digital data processor.

Olympia gas wall heaters are equipped with safety devices, which protect the system from damage, caused by lack of traction in the chimney, overheating of water, gas leakage, a sharp drop in temperature.

When installing the equipment is possible coaxial installation (twins) flues. This will significantly reduce the cost of purchasing and manufacturing a chimney.

The wide range of capacities of Olympia units allows to pick up model, which will be suitable for a particular room.

The range of wall-mounted contour gas equipment from Korean manufacturers allows you to choose a heating system with premium features and the cost of standard equipment from European manufacturers.
