Danko gas boilers - technical characteristics of models, reviews from owners

The Ukrainian brand Danko is known primarily for gas boilers. A clear advantage is their low cost. The range also includes parapet gas boilers, installed in private houses or apartments where it is not possible to install a chimney.

In the article we will look at the best models of Danko gas boilers, how they behave in practice, what advantages and disadvantages the owners note, as well as what malfunctions may arise during the operation of boiler units in real conditions.

About the manufacturer

The Danko trademark is managed by PJSC Agroresurs; the first batch of boiler units was produced in 2002. The company is represented in the markets of Ukraine, Russia, Belarus and Moldova, where it has established itself as a manufacturer of relatively reliable and efficient gas boiler units for their price. It’s not uncommon to find the first batches of 2002 in homes.

The design and principle of operation of Danko gas boilers in a section using the example of a double-circuit steel model 12VSR.

Heating boilers are produced using modern foreign equipment, automation is imported from Italy in finished form. Almost all boiler units have high efficiency - over 90%. However, there are also disadvantages - the assembly is of insufficient quality, problems with the automation are possible during operation, due to the simplicity of the device and low cost, the boilers do not have a wide range of functionality or a set of protective systems. Installers note the relative complexity of installation and connection.

In practice, during strong gusts of wind in versions with a horizontal gas duct, the burner often blows out and the flame goes out, but the automation does an excellent job and turns off the gas supply. After this, the boiler must be ignited manually. The above-described disadvantages are typical for any inexpensive boilers of Russian, Ukrainian or Belarusian production.

Boiler installation

Installation of Danko gas boilers and connection to the gas main is quite easy. For comfortable operation, the housing includes left and right connections. When installing, it is very important to follow the following expert advice:

1. The gas supply is regulated manually using automation. To increase the power of the unit, set the required mode using a rotating wheel.
2. The Danko wall-mounted gas boiler is mounted using anchor bolts. During operation, the maximum weight of the device is 80-100 kg. It turns out that the fasteners must be very reliable to withstand such a load. With proper installation of the boiler, possible excessive fuel consumption and other problems can be eliminated.
3. To minimize gas consumption, an external temperature sensor can be used. The operation of the device is to determine the ambient temperature, as well as auto-adjust the specified mode of the boiler equipment. The temperature sensor works in this way: it records the ambient temperature and transmits information to the controller. Automation detects changes and introduces them into the specified temperature regime. As a result, gas consumption becomes lower.
4. Chimney – can be connected to a classic and coaxial smoke exhaust system.

Fire safety requirements for the installation of parapet devices are not as high as for atmospheric models. Therefore, in apartments it is recommended to install models with a closed combustion chamber.

The article described all the distinctive features of the brand’s heating devices, the installation of boilers, and examined their possible operating problems: why a Danko gas boiler goes out, goes out and takes up a lot of fuel. Take note of the recommendations of experts, reviews of owners, and the heating unit will serve you for a long time.

Features of operation and setup

Annual cleaning of the chimney is recommended so that the quality of work does not decrease.
The requirements are set out in the user manual, which should be carefully studied before starting to work with the unit. During the operation of boilers, the following unforeseen situations are possible:

• The product does not turn on.
• The boiler starts to turn off randomly.
• In strong drafts, the burner may go out.
• The draft is noticeably reduced (for products with natural ventilation).

To eliminate the first two malfunctions, you should invite specialists. During operation, it is important to remember the need to periodically clean the chimney, which over time becomes clogged with combustion waste.

The need to adjust the boiler’s functionality may be required when it is necessary to increase the efficiency and stability of its operation. To do this, you will have to invite a service center specialist or representatives of the warranty workshop. Self-tuning can lead to complete failure of the equipment.

The best and most famous models: characteristics and prices

8C

Low-power 8 kW single-circuit floor-standing boiler, one of the most inexpensive in price. Designed for a house with an area of ​​up to 70-80 m2. The design and principle of operation of the model are as simple as possible: open combustion chamber, steel heat exchanger (C in the name), SIT automation (Italy).

The boiler has a high efficiency of 92% and a particularly low gas consumption - 0.9 cubic meters. m/hour. Unlike other models, it is equipped with a vertical gas duct, which prevents the burner from being blown out by the wind. The only protection is to prevent overheating and gas control.

Cost on average 18,000 rubles.

12VSR

A double-circuit floor-standing boiler with a power of 12 kW, designed for heating a house with an area of ​​up to 120-130 m2. This is one of the best Danko boilers for heating a private home.

It is distinguished by the presence of a second circuit, that is, water heating (B in the name), hot water productivity at a temperature of 35°C is 4.93 l/min. The volume of hot water supply is sufficient for a single consumption; for more intensive use (eg bathing and kitchen tap at the same time), the power may not be enough. It has a steel heat exchanger and is capable of operating not only on natural gas, but also on liquefied bottled gas (P in the name).

Efficiency is 91.5%, and natural gas consumption is 1 cubic meter. m/hour. The boiler is energy-independent, the gas outlet is organized vertically, which greatly reduces the risk of blowing out and subsequent attenuation. The disadvantages are also the loud ignition sound, lack of auto-ignition and flame modulation, however, for such a price, these functions are rarely found on dual-circuit models.

Cost – 24,000 rubles.

12.5US

An improved parapet boiler with a power of 12.5 kW is designed for installation not only in private houses, but also in apartments.

Parapet boiler systems have a closed (sealed) combustion chamber and do not require connection to a traditional chimney. They can be installed in any room where there is at least one external wall, through which a side coaxial chimney (pipe within a pipe) is subsequently discharged. It is installed in the apartment in the window sill and requires only a gas pipeline, since it is energy independent.

Gas consumption 1.4 cubic meters. m/hour is optimal for this power and price category, although higher than the classic convection models 12BP or 12P. One of the few truly quiet Danko boilers. Apart from the dubious build quality and narrow functionality, no shortcomings were found due to the practice of use.

Cost – 24 thousand rubles.

16HP

Cast iron single-circuit boiler with a power of 16 kW, designed for heating a house with an area of ​​up to 150 sq. m. A cast iron heat exchanger is usually used in more expensive modern models and has a significantly longer service life - over 25 years. It takes longer to heat up, but it also takes much longer to cool down, continuing to give off heat even after the burner is turned off.

Gas consumption is not outstanding, but optimal 1.9 cubic meters. m/hour, and efficiency is 90%. The disadvantages are the absence of any automatic protection systems and the significant weight of the heating unit - 97 kg. The cost of a boiler is on average 34-37 thousand rubles. , which is still significantly lower than foreign analogues, prices for which start from 45-49 thousand rubles.

Model "Danko 10/12": design and installation features

Using the Danko 10/12 model as an example, let's look at the structural features of the boiler, as well as what needs to be taken into account when installing it, regardless of the fact that the installation will be carried out by specialists.

What does the Danko 10/12 floor-standing boiler consist of?

This model is equipped with a built-in water heater and is intended for heating residential private houses and public utility buildings.
"Danko 10/12" is a rectangular floor cabinet, the front side of the structure is closed with a door, which provides access to start the boiler into operation. Its main parts are:

• heat exchanger;
• burner;
• gas automatics;
• decorative casing.

The system’s automation is needed to supply fuel to the main and ignition burner, and it also regulates the water temperature. In addition, the gas supply can be urgently turned off in the following cases:

• if the ignition burner goes out;
• if the gas pressure is below the minimum;
• if there is no draft in the chimney;
• if the coolant has heated up above 90 degrees.

Installation features

When installing Danko equipment, you need to consider the following:

• the power of the equipment must correspond to the heating project;
• the unit is installed on a fire-resistant horizontal base at a distance of at least 25 cm from non-combustible walls;
• if the walls are non-flammable, the device can be installed with non-combustible walls, provided they are insulated with steel sheets;
• the passage in front of the boiler must be at least a meter wide;
• so that water circulates better, the boiler is placed below the level of heating devices;
• the expansion tank is installed at the highest point of the system;
• the chimney in the room must be at least 5 meters in length from the level of the main burner;
• if the chimney is located along an external wall, its outer part is insulated along its entire height;
• the cross-section of the chimney duct must be larger than the cross-section of the chimney pipe;
• the junction of the boiler and the chimney must be sealed with clay or cement mortar.

Each model is accompanied by a detailed description of the device’s features and technical characteristics, as well as an electronic copy of a full operating manual, which describes the installation diagram, the algorithm for switching on and adjusting the operation, maintenance features, and contains clear schematic images.

Which boiler model is ultimately better to choose?

If you decide to opt for Danko, it is not difficult to decide on a model; we recommend choosing from the most successful models described above. The main selection criteria are the minimum required power, the need for a second circuit for hot water supply and the budget.

One of the most budget-friendly gas boilers on the market as a whole is Danko 8C, which has enough power to heat a house with an area of ​​up to 70 m2. For average house sizes (100-120 m2), models 12CP (single-circuit) or 12VCP (double-circuit) are suitable. With an area of ​​120-140 m2 or more, it is better to choose a model with a more efficient and reliable cast iron heat exchanger - 16HP or its more powerful versions.

Parapet models are intended, as a rule, for installation in an apartment; their choice is limited only by the minimum required power (simplified - 1 kW for every 10 m2 of area + 10-20% power reserve).

Possible problems during operation

The most common and almost the only problem with Danko gas boilers is the burner (pilot) going out. The cause is usually strong gusts of wind, icing of the chimney or its contamination with combustion products. To prevent blowing, we recommend installing a check valve in the chimney. To prevent clogged chimneys, it is important to have your chimney cleaned annually (or do an unscheduled cleaning to deal with the problem now).

A more rare problem that occurs in severe frosts (-15°C and below) is icing of the chimney. In addition to mechanical elimination, there are chimney designs that prevent icing.

Ready-made design of a side chimney that prevents icing.

There are also complaints about excessive smoke production during operation. Typically, a gas boiler smokes when there is a significant layer of soot in the chimney, formed due to untimely cleaning. Combustion products settle on the chimney especially quickly when using liquefied gas. Also, the reason may be that a cold boiler is started immediately at maximum power; we recommend increasing the temperature gradually.

If parapet models knock when heating or cooling in a certain temperature range, check the slopes, the pipes may have sagged and air has formed in the CO.

Please note that after extinguishing, unlike more expensive models with advanced automation, the burners of Danko boilers do not light up on their own and require intervention.

How to light a Danko gas boiler

Identification of boiler control elements.

1. Turn the mechanical temperature regulator counterclockwise until it stops.
2. Make sure that the tap on the gas pipeline inlet is open.
3. Press and hold the start button, then press and release the piezo button (several clicks may be required, repeat until the pilot burner lights up). Hold the start button for at least 30 seconds until the burner goes out when it is released. If the boiler has not been adjusted previously, it may be necessary to adjust the air supply by turning the nut on the ignition burner until the burner flame turns blue.
4. Turn the thermostat knob clockwise until the main burner turns on, then set the desired power.

The startup process differs slightly for configurations with different automation; the algorithm is described in detail in the operating instructions, an electronic copy of which is attached in the description of each model on the official website.
