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.
What is a single-circuit boiler
The device in question is a device that has one heat exchanger that heats water, antifreeze or air, that is, a coolant.
With the standard configuration received from the factory, it cannot be used for heating water and its further use for various household needs. It is this device that is called a single-circuit boiler. Such heating systems are aimed, first of all, at heating rooms by creating the necessary comfortable temperature in them.
The name is given by the type of device itself, that is, a single circuit passes through the structure through which the heated substance circulates. And if the factory equipment of the device does not allow you to immediately install the system with the connection of a boiler for hot water, then in the future you can do it yourself.
Circulation within the system itself occurs due to the fact that a special pump operates and there is a large difference in the temperature of the substance being heated. In order for all the necessary rooms inside the house to be heated evenly, circulation must proceed without disturbances.
If we consider the issue of additional heating, which can be carried out outside the circuit itself, then it can be done independently and without much effort. But when using a single heating circuit, if you also load it with heating a large volume of water in the boiler, then this situation will immediately have a negative impact on the heating operation. Since productivity will decrease and fuel consumption will increase.
Therefore, if the house has low hot water consumption, it certainly makes sense to connect a small boiler, but if a lot of water is used and it is used frequently, then such an expenditure of funds is quite unprofitable.
This type of device has its advantages:
- These heating structures are equipped with a system that automatically monitors safety. It also sets the optimal parameters for the operating mode and consumption of the supplied fuel;
- such systems are convenient to install throughout rooms; in order to heat them, this does not require a large team of workers or special equipment;
- the period during which such a boiler can be operated is quite long if the installation is properly maintained;
- modern units have the ability to use a sensor to respond to changes in the weather and automatically either heat up or switch to a more gentle mode of gas fuel consumption;
- Since the design is quite easy to use, this also creates a certain comfort when using it.

Why doesn't the boiler start?
Often problems are shown as an error code on the display. All modern models Vaillant (“Valiant”), Baxi (“Baxi”), Ferroli (“Ferroli”) are equipped with a self-diagnosis system. Each brand has its own codes and their meanings. If the display does not show symbols, then you need to look for the cause of the problem yourself.
Problems with wall and floor units can be caused by external and internal factors.
External ones include:
- Insufficient gas pressure in the main;
- Chimney problems;
- Power surges in the network;
- Draft, low temperature in the room/boiler room.
Internal factors include breakdowns of electronics - sensors, wiring, as well as individual components - pump, heat exchanger.
Boiler design using the example of Danko 10/12
The model has a built-in water heater - it can be used to heat a private home and heat hot water. Appearance: rectangular cabinet. The facade is equipped with a door that closes and provides access to the elements responsible for ignition. Comprises:
- burners;
- heat exchanger;
- gas automation;
- decorative casing.
The automatic unit is responsible for supplying fuel to the burners - main and ignition, and for regulating the water temperature. Gas flow stops immediately if:
- the flame went out;
- the gas pressure has dropped below the permissible value;
- there is no draft in the chimney;
- The coolant temperature reached 90 °C.
Double-circuit modifications consist of structural elements:
- chimney duct;
- blower fan;
- gas burner;
- heat exchangers – primary and secondary;
- hydraulic unit;
- connecting fittings;
- pump for forced water circulation;
- expansion tank;
- an automation unit that controls the units of the device.
A distinctive feature is that all components are produced by European companies. This is a plus in favor of the reliability and cost-effectiveness of Danko brand products.
Solid fuel boilers for private homes
Of course, the most common fuel is gas, but there are a number of alternatives - for example, solid fuels such as wood, coal and coke.
There are two types of solid fuel devices:
- Universal. Quite popular and expensive designs that can operate on any type of solid fuel - and this greatly simplifies the process of preparing fuel for the boiler.
- Operating on a single type of fuel. Such equipment is not universal, but focusing on a specific type of fuel allows you to optimize the operation of the device and increase its efficiency.
The main disadvantage of solid fuel boilers is the inability to operate in autonomous mode. The problem is the need to constantly add fuel, which requires a considerable investment of time and effort. In addition, fuel must be stored somewhere - and this can cause additional complications if there is not much free space.

Due to moving to a new house, we needed to change the boiler.
I wanted to buy a wall one. This is what was important to me. And I also didn’t want to buy a cheap wall-mounted boiler, but then overpay for fuel consumption. Of course, reviews and discussions about such boilers, which I found on a variety of forums, amazed me with their advantages, but for myself I chose several manufacturing companies, among which was a wall-mounted boiler.
Makhachkala, Republic of Dagestan
The modern market provides a large selection of goods and services. And every time you are faced with which manufacturer to choose. It would seem that it makes no difference, because a car is a car, an iron is an iron. But when you come to the store, they offer you the same product in different versions. This is where the problem arises - “What to choose?!”

requirements
1. single-circuit
2. there is a chimney (from an old “Soviet” boiler), so if you can connect a new boiler to an old house flue, then a chimney is better, they seem to be cheaper)
3. so that it works depending on the temperature in the room (you could set the temperature to whatever you want, if we are leaving for several days, set the minimum to non-freezing)
4. Now the old boiler works with batteries using natural circulation. however, the circulation is poor, the house at minus 20 with the boiler at maximum warmed up to 16 degrees and that’s it. But with not such severe frosts everything was fine. I would like to install it with a pump, it saves gas consumption, but there are power outages for 8-12 hours. There hasn't been anything else yet, but anything can happen. Are there boilers in which the pumps can be turned off (during a power outage) and it would continue to operate on natural circulation?
5. I don’t know whether it’s wall-mounted or floor-mounted, they say floor-mounted ones are more reliable and durable

Ease of use
Advantages: Closed combustion chamber Can be installed in an apartment Takes up little space Has a water heating function (DHW) Works well at low gas pressure.
Feedback: More than a year ago, we were concerned about installing individual heating in the apartment instead of central heating, since it was turned on late and turned off early - as a result, the whole family froze in early spring and mid-autumn. Since there wasn’t a lot of money at that time, it took a long time to choose a domestic boiler (European ones were almost 2 times more expensive) and eventually settled on this Danko wall-mounted boiler: https://finistd.ru/for-buyers/product-catalog/wall -hung-boilers-danko-23-kw We have this boiler...

What are the pros and cons of Danko boilers?
The main advantage of Danko gas appliances is that they are assembled using technology purchased from European manufacturers. And this distinguishes Danko boilers from other Ukrainian and Russian manufacturers of similar products. Having studied the reviews of the Danko gas boiler, you can be convinced that these units have a lot of positive aspects.
Among the many positive features, it is worth highlighting the most important:
- gas boilers can operate efficiently at reduced gas pressure (up to 2 Mbar);
- quiet operation;
- heating occurs very quickly. This was made possible thanks to the presence of a copper coil;
- the unit is equipped with safe and reliable automation (Kare or Sit);
- thanks to the steel heat exchanger, heat transfer is significantly increased;
- reasonable price. The cost of Danko gas boilers varies depending on the specific type and model of the unit. For example, the price for a Danko floor-standing gas boiler will differ from wall-mounted units. The price depends not only on the specific model, but also on the power and type of automation. But still the products are available to every buyer;
- the warranty period is 3 years;
- long period of operation - about 25 years.
The reviews for the Danko single-circuit floor-standing gas boiler are mostly positive. Consumers note reliability, uninterrupted operation, and durability. Many people also include the advantage that during the warranty period, all components and spare parts are delivered at the expense of the manufacturer. And repairs are provided by plant employees or gas services.
Of course, like any equipment, Danko boilers are not without drawbacks:
- the chimney needs to be cleaned periodically;
- When looking at reviews of the Danko floor-standing gas boiler, you can note its noisier operation compared to wall-mounted options;
- if the flue is horizontal, a strong wind can extinguish the flame in a gas boiler;
- The power of wall-mounted models is lower than that of floor-standing counterparts.
Without knowing what type of unit is best to purchase: a gas boiler from a well-known imported manufacturer or a Danko wall-mounted single-circuit gas boiler, reviews can in this regard become a decisive factor in making a purchase. Many consumers have already appreciated Danko's products and recommend using only devices from this company.
Comparison of gas floor-standing boilers - 5 BRANDS 07/13/2016 09:33
When choosing a gas floor-standing boiler, you should pay attention to the following:
1. Gas valve or gas automation:
Most manufacturers equip their boilers with the same gas automatic Eurosit 630 made in Italy. The gas block is very reliable and the number of complaints about them is less than 0.2%. Since 2012, Zhukovsky Machine-Building Plant began equipping boilers with gas valves manufactured by Mertik Maxitrol (Germany). This is an analogue of the unit - Honewell V5474G1088B.
Also a reliable block. The Germans have always been distinguished by quality! However, models equipped with European automatic equipment are an order of magnitude more expensive than models with domestic units. If you decide not to overpay and save, then we will support you, because... Over the course of several decades, Russian factories have learned to make high-quality domestic automation. The functionality of all blocks is similar. Mertik Maxitrol models have units with a built-in ignition indicator.
What series and models are floor-standing
The range of Danko floor-standing boilers is wide and includes several series.
Household models include the following lines:
- Danko SR or HRV. This is a series of single- and double-circuit domestic heating boilers with a 3 mm thick steel heat exchanger. Includes models with a power of 8, 10, 12, 15, 18, 20 and 24 kW. They are capable of heating houses with an area of 80 to 250 m2, which corresponds to the usual size of a private house.
- Danko SN and VSN. The units of this series have increased power, ranging from 30-48 kW. The main design features are the same - single- and double-circuit gas boilers with a steel heat exchanger.
There is also a series of Danko gas boilers with a cast iron heat exchanger. They are more massive and heavier due to the dimensions of the cast iron container, and have increased efficiency.
The ability of cast iron to transfer heat is higher than that of steel, which makes boilers more efficient and powerful.
There is a series of boilers for use in large industrial or public premises, the power of which reaches 96 kW. They are capable of heating up to 900 m2, and when connected in a cascade, the capabilities of the units increase accordingly.
What problems happen?
The simplicity of Danko's design allows its owners to carry out minor repair work on their own. One of the most common problems is the burner blowing out. This is especially common in strong winds. Usually no fault is found, the wind is the culprit of the problem, but it is better to check the following points:
- Is there a check valve installed in the chimney? If not, then there will be no reverse thrust, which is why attenuation occurs.
- If the chimney is installed incorrectly, it becomes clogged with soot and other combustion products - it needs to be cleaned.
It happens that before the attenuation, extraneous noise is heard or increased fuel consumption is observed - this may indicate a failure of the controller. The task is to repair or replace a spare part.
Another common problem is the pilot light going out. It goes out due to the activation of the thermostat, which shuts off the gas supply if the burner does not heat up to the desired temperature.
Recommendations
Despite the fact that Danko boilers have a long service life and reliability, some breakdowns still occur.
Therefore, all owners of gas equipment should know the main types of malfunctions and the causes of their occurrence.
- The formation of soot and soot on the internal surfaces of the boiler indicates problems with the chimney. In this case, you should clean the pipe from accumulated combustion products and wash the parts of the device from dirt.
- Unstable operation of the device and temperature fluctuations in the system indicate a malfunction of the fan or circulation pump. If you have the necessary spare parts, you can repair the device yourself.
- If the boiler's pilot light goes out or the wick does not light, the reason is most likely the absence of a special valve in the chimney system that prevents backdraft. The igniter going out may also be due to the thermostat tripping. In this case, adjustment of the device is necessary, which should be done by experienced specialists. Only single-circuit boilers are subject to attenuation. In dual-circuit devices, such problems are not observed.
- If the combustion sensor or pipe fails, the device is urgently disconnected from the gas supply and left to cool. Repairs can only be performed when the breakdown is not related to a fuel leak. For example, cleaning the pipe can be done independently, but more serious faults should only be trusted to a specialist.
- Increased fuel consumption and the presence of extraneous noise before attenuation are most likely caused by a failure of the controller. If you have the necessary spare parts, you can repair the part yourself.
In the next video you will find a review of the Danko 12.5 TN solid fuel boiler.
This is caused by the desire to save on paying for network resources, the unavailability of connecting to a central heating center in remote cottage villages, or other reasons.
There are a large number of samples of heating devices on the market, of which gas boilers are unanimously recognized as the most effective.
They are produced by all well-known companies in Europe and Southeast Asia.
Manufacturers from the countries of the former USSR are not lagging behind, their products are able to successfully compete with European models.
Basic faults
The most common malfunctions of Danko gas boilers, experts and ordinary users include problems with the burner and gas consumption.
Cases of flame attenuation (failure), characteristic of boilers with an atmospheric burner, are often noted. In addition, the injectors often become clogged with soot, soot and other combustion products. Excessive gas consumption occurs due to the appearance of a layer of scale in the primary heat exchanger.
It acts as a thermal insulator, reducing the efficiency of heat transfer. The user notices that the coolant temperature has dropped and increases the flame burning mode.
This causes the heating of the outer surface of the heat exchanger to become stronger, which causes rapid failure of the unit.
The solution to the problem is the use of softening water filters (as a preventive measure) and periodic washing of the heat exchanger, for which you need to invite a technician from the service center.
IMPORTANT! Attempts to independently solve any problems can cause boilers to fail. In addition, interference with the design of boilers becomes the reason for termination of the warranty agreement
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.
Possible operational problems
During operation, any equipment can fail, no matter how reliable the automatic protective equipment is. Danko boilers have a simple design, which allows you to correctly carry out minor repairs yourself. Let's look at the main malfunctions, why they happen and how to solve them.
How to start a gas boiler
Any Danko boiler can be lit semi-automatically:
- The regulator handle is placed in the extreme position.
- When the wheel is pressed in, gas is supplied to the burner and ignited by a piezoelectric element.
- After starting the pilot burner, you must keep the wheel pressed in for 5-10 seconds.
- If the burner goes out when you release the latch, you must repeat the previous manipulations again.
Blows out the boiler
This problem occurs quite often, especially in windy weather. Most often, there is no malfunction here, and repair of the device is not required; you need to check the following factors:
- During installation, a check valve was not installed in the chimney. For this reason, backdraft occurs and the burner goes out.
- If the chimney is not installed correctly, it can become clogged with soot and other combustion products. In this case, it is necessary to clean the chimney.
If the constant extinguishing of the boiler was preceded by extraneous noise in the burner or increased gas consumption, the controller may have failed.
It needs to be replaced or repaired. Ukrainian-made Danko boilers are a good alternative to expensive models of heating equipment from Europe. Durability, simplicity and reliability of design, full adaptation to harsh operating conditions - these are the main advantages of boilers from this manufacturer, as confirmed by numerous consumer reviews.
Advantages and disadvantages
The advantages of Aton boilers should be considered:
- Reliability, strength of all components and parts.
- The ability to perform all necessary functions - heating and hot water supply.
- Availability of non-volatile models that can operate without being connected to a power supply.
- Wide choice of design and functionality.
- Stability, stability of operating modes.
- Compact, attractive appearance.
- Long service life, reliability.
- Relatively low price.
The disadvantages include:
- Volatile models become useless if there is a sudden power outage.
- Non-volatile models operate using natural physical processes that are unstable and unstable.
- High sensitivity to water quality, gas purity and power supply voltage stability.
IMPORTANT! The disadvantages of Aton boilers are common specific features of all such units.
How to choose?
Before you start choosing a model, you need to determine the functional purpose of the boiler and its power. Double-circuit units should be selected if you plan to equip not only heating, but also hot water supply
Particular attention should be paid to the heat transfer coefficient of the device, which is especially important when calculating the power of the heating system in regions with cold climates. Convection models have the highest efficiency. This type of design is presented in many Danko floor-standing appliances and is recommended for use in northern regions

Judging by the reviews of the owners, it was convection boilers that showed their best performance when heating a private home in harsh conditions. In addition, floor-standing devices are non-volatile. In the event of a power outage, they will not leave the house without heat. The most popular model among floor-standing appliances is the Danko 18BC model. The boiler has dimensions of 41x85x49.7 cm, weighs 81 kg and is designed to heat a room up to 170 m².
For heating country houses or when installing a heating system in southern and temperate latitudes, wall-mounted and parapet units are quite suitable. These devices can effectively warm a medium-sized room and provide residents with uninterrupted hot water supply. The disadvantage of such devices is the presence of electronic ignition, which does not allow the boiler to light in the absence of electricity.
Many models are equipped with frost protection, which is important when operating the device in conditions of temperature changes in the absence of owners, when it is not possible to force the device to turn on or off
When choosing equipment, you should also pay attention to fuel consumption. Single-circuit devices consume significantly less gas than double-circuit models. For example, a floor-mounted single-circuit unit of the Danko 8 brand, having a heat transfer coefficient of 92% and capable of effectively heating a room of 70 square meters, consumes only 0.9 cubic meters of gas per hour, while some double-circuit boilers consume 2.5 and more than cubic meters of fuel
For example, a floor-mounted single-circuit unit of the Danko 8 brand, having a heat transfer coefficient of 92% and capable of effectively heating a room of 70 square meters, consumes only 0.9 cubic meters of gas per hour, while some double-circuit boilers consume 2.5 and more than cubic meters of fuel.
