Wall gas boilers Daewoo Gasboiler (Daewoo Gazboiler)

Most homeowners choose to build a self-contained heating system.

Sometimes this decision is made even if it is possible to connect to a centralized network.

The reasons for this choice are the desire to independently regulate the heating mode and too high utility rates.

There are a lot of gas heating boilers on the market, which are recognized as the most efficient and economical of all the alternatives.

Consider Daewoo gas boilers, which are one of the most advanced groups of heating equipment.

Daewoo gas boilers

The Korean industrial giant Daewoo is known all over the world primarily for its cars. However, the range of products is much wider and includes many different positions and directions.

The name of the Daewoo company is translated into Russian as "The Great Universe". It was founded in 1967 and the first gas-fired boiler left the assembly shop in 1988. Today the company is a global corporation with many branches and related companies.

Active research and development is underway, the result of which is the emergence of new designs, assemblies and parts.

For example, the electronic ignition system was first implemented on Daewoo gas boilers..

The range of heating boilers manufactured by the company is wide enough. All the most promising designs are produced, capable of providing stable and trouble-free operation for a long time.

The company aims to produce relatively inexpensive, but very reliable units. This is achieved by eliminating minor or low-demand components that increase the cost of equipment without bringing any noticeable benefit.

In addition, more efficient and inexpensive models of important components have been developed - for example, a new type of three-way valve, more reliable and easier to manufacture.

A feature of Daewoo boilers is a relatively low power, designed for use in small private houses. This approach demonstrates targeting the mass customer, and it yields positive results.

For example, it was possible to reduce fuel consumption by 7-10% by reducing the number of gas burner sections.

Daewoo MSC series

Daewoo MSC boilers are double-circuit devices with a closed chamber, the rated power of which, depending on the modification, can range from 7 to 46.5 kW. This line of units is represented by 8 different models.

This technique has some peculiarities. In particular, its main heat exchanger is made of copper, which provides the equipment with a long service life. In turn, the heat exchanger for hot water supply has a plate-like shape, which provides rapid heating of the coolant. The burner installed in Daewoo MSC boilers is made of stainless steel. At the same time, the unit is equipped with all the necessary automation and security systems. The boiler can be controlled using a remote control with an LCD display.

The device has several modes that make it easier to control its operation. Among them:

• "Heating";
• "DHW";
• "Heating + DHW";
• "Minimum heating";
• "Accelerated DHW"
• Etc.

The coaxial chimney of the MSC unit prevents the burner flame from blowing out in the event of sudden gusts of wind outside the window. It is possible to install separate chimneys, which is important when heating several apartments. The factory design of the MSC boiler is designed to operate on natural gas, but the nozzles can be changed at any time and the unit will be able to operate on liquefied fuel.

findings

Daewoo boilers today are represented by a large selection of heating systems offered on the domestic market for relatively little money. If you are looking for reliable and at the same time innovative equipment, but are not ready to overpay for European units, then the equipment of the South Korean brand will suit you perfectly.

Views

Daewoo produces the most popular and convenient wall-mounted gas boilers for use in a private house.

There are no floor models in the company's arsenal, which is not a drawback, but it demonstrates the approach of the company's engineers to creating the most compact and multifunctional models.

There are two options for the type of combustion chamber:

• Atmospheric boilers... The combustion chamber is open, and the intake of air necessary for combustion and smoke removal is carried out directly from the room in which the boiler is installed. They are connected to a common house chimney and require the creation of certain conditions for work. DO NOT tolerate drafts or strong gusts of wind outside - the flame may go out.
• Turbocharged boilers... The air is supplied by a turbocharger fan. This design makes the boiler completely independent of external factors, and the operating mode is stable and stable. Connecting the boiler to a common chimney is not required, special chimneys of the coaxial type ("pipe in pipe") of the horizontal type are used, which can be led directly from the room through the wall. Forced air units are stable and in higher demand.

By the type of heat transfer, there are:

• Convection boilers... They work on the usual principle - heating the coolant in the burner flame.
• Condensing models... Construction of a new type, which uses a two-stage heating of the coolant. First, the thermal energy obtained from the condensation of water vapor from the exhaust smoke is used. Then the coolant, which has received some heating, is sent to the primary heat exchanger, where it is finally heated to a predetermined temperature.

The use of condensing boilers has started recently, but statistics have already been collected. They provide significant fuel savings through the reuse of thermal energy.

It becomes possible to reduce the heating intensity of the heat exchanger, which saves gas and increases the service life of the boiler components that are not exposed to too much stress.

NOTE!

Condensing boilers require specific operating conditions. The temperature difference outside and inside the building must not exceed 20 °, otherwise the condensation process will become impossible. Because of this feature, the use of condensing boilers in Russia does not make sense. When purchasing such installations, you should know in advance about the existing restrictions so as not to pay extra money.

Daewoo atmospheric boilers

The line is presented in four positions, with a capacity from 12.8 to 23.3 kW. In terms of technical characteristics, atmospheric boilers DEU do not differ from turbocharged ones. The only exception is the consumed electricity - there is no fan for the coaxial chimney. At the same time, the principle of their work is somewhat different. Mainly due to the design of the combustion chamber. In atmospheric boilers, it is leaky. Accordingly, the air for maintaining the flame comes directly from the room where the heater is installed.

For the operation of the equipment to be safe, it is necessary to provide for a constant flow of fresh air into the room. This can be done the old fashioned way by ventilating the room, or you can install an air recuperator.

For atmospheric boilers, DEU needs a chimney. The installation must be approached with all seriousness: there are a number of requirements that must be followed without fail.

Remember, the chimney is one of the key elements in the heating system (see Arrangement and connection of the chimney for a gas boiler). Improper installation or insufficient insulation can lead to the appearance of such undesirable consequences as:

• lack of traction;
• the appearance of reverse thrust - the ingress of carbon monoxide into the room is deadly;
• the appearance of condensation, which corrodes the chimney.

In atmospheric boilers, DEU malfunctions occur less often than in turbocharged ones. The principle works here: the fewer structural elements, the lower the probability of breakage. In this regard, the absence of a fan for circulation can be regarded as an advantage.
