Advantages and disadvantages of Danko gas boilers + operating instructions and owner reviews

Autonomous heating systems for a private home, created on the basis of gas boilers, are considered the most efficient and economical.

They allow you to solve heating problems in the absence of the ability to connect to centralized networks, and in some cases, users themselves prefer to create their own independent system.

The number of manufacturers producing heating gas boilers is large and constantly growing.

European companies are recognized leaders in this area, but the developments of companies from the countries of the former USSR are beginning to squeeze them out in the market.

The reason for increasing competitiveness is our own conceptual approach to the manufacture of gas boilers, which can be considered using the example of Danko floor-standing models.

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.

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:

1. 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.
2. 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.

Instructions ↑

The operating instructions for Danko gas boilers prescribe that commissioning begins only after acceptance by gas industry specialists and their instruction. All repair or maintenance work is carried out by specialists who have permission to carry out such work.

Attention: When choosing a boiler, you need to take into account the type and power of the equipment, which are indicated in the project developed by the gas industry. Installation of gas boilers is carried out only by specialists licensed for this type of work

When operating, you must follow a number of safety rules:

1. Only trained persons can service the boiler.

2. If the boiler is not working, the taps must be turned off.

3. If you smell gas, you need to turn off the gas tap, open the windows in the room where the boiler is located, and call the emergency gas service.

4. The boiler must be maintained in good condition and clean.

5. If there is a chimney, it is necessary to periodically clean it.

6. It is necessary to check the filling of the system once a week, this is determined by the presence of water in the expansion tank.

7. After the end of its service life (15-25 years), you will need to call a specialist from a service company who will decide on the possibility of its further use.

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?!”

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?

October 25, 2014

If you want to purchase a suitable boiler to connect to the heating system, it is better to look not at expensive Italian options, but to opt for more affordable, but no less effective models. Thus, the Danko gas boiler is the best among popular domestic products

. Its main quality is the variety of models. Due to the wide range, you can always choose the right model.

Danko boiler

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.

Owner reviews of Danko gas boilers: advantages and disadvantages

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 house.

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 .

Review of Siberia gas boilers One of the most reliable among domestic boilers

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 .

Is it worth considering parapet gas boilers for heating a private home?

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.

Official website: where to view all models and operating instructions

A snapshot of the website of the official representative in Russia.

In Russia, the official website is located at https://www.danko-rus.ru/.

By going to the Product Catalog you can see all available models, sorted by type. 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, the power of which is sufficient to heat a house with an area of ​​up to 70 m2. For the average size of a house (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 - 16 HP 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 m 2 of area + 10-20% power reserve).

How to calculate the required boiler power for heating a private house

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.

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:

1. gas boilers can operate efficiently at reduced gas pressure (up to 2 Mbar);
2. quiet operation;
3. heating occurs very quickly. This was made possible thanks to the presence of a copper coil;
4. the unit is equipped with safe and reliable automation (Kare or Sit);
5. thanks to the steel heat exchanger, heat transfer is significantly increased;
6. 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;
7. the warranty period is 3 years;
8. 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.

Price range

Danko floor-standing boilers represent a wide group of models, which expands the price range. If you do not take into account powerful samples intended for heating large areas, then the cost of floor-standing boilers is in the range of 20-67 thousand rubles.

The price of a particular model depends on the set of functions and design features.

Before purchasing, you need to decide on the type of chimney, since this is an important factor influencing the choice of a particular model.

NOTE! The chimney is not included in the basic package and must be purchased separately.

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.

Technical characteristics

Let's look at the parameters of Danko floor-standing gas boilers:

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.

Features of operation

When purchasing a Danko floor-standing gas boiler, instructions are included with each model of the unit. And this document must be carefully studied before proceeding with installation and operation. Preventive inspection and repairs should only be performed by a qualified technician who has permission to carry out work of this nature.

To extend the service life and ensure safe operation of the device, it is important to follow these rules:

1. in case of breakdown, turn off the tap;
2. if there is a smell of gas in the room, you must immediately turn off the tap, open the windows and call the emergency service;
3. from time to time it is necessary to check the chimney and clean it;
4. Check the expansion tank weekly for the required water level;
5. If the service life of the unit has expired, you should call a specialist to assess the condition of the device and make a decision regarding the possibility of further operation of the gas boiler.

Thus, we can conclude that gas boilers are widely used today for heating supply system equipment. You can read about choosing a gas boiler for your apartment here. Ukrainian Danko units are very popular in the modern market. Their quality is on par with foreign analogues, and the cost is an order of magnitude lower. During operation of boilers, they must be periodically inspected and maintained. And in case of breakdown, immediately contact a specialist for help.

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

Device

The design and structure of Danko gas boilers are based on the latest developments, to which only minor amendments have been made to eliminate unused or minor functions and components. The main elements are the heat exchanger-gas burner connection .

They work in pairs and prepare coolant for the home heating system. Hot water is heated in a secondary heat exchanger due to partial extraction of coolant energy.

The final preparation of the liquid occurs in a three-way valve, which mixes the cooled return flow with the hot coolant in a given proportion, after which the heating agent enters the heating circuit.

Smoke removal occurs naturally using draft in the chimney, and circulation is provided either by an external pump or it occurs naturally.

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.

User manual

The boiler operates automatically. The user is only required to maintain the cleanliness of the body, fill and drain water from the system and start the boiler when necessary.

Temperature adjustment is carried out in operating mode, according to the user’s own feelings. The boiler is started either using a piezo ignition system or manually using the principle of a gas stove. To turn on the boiler using piezo ignition, you need to turn the knob to the ignition position.

The thermostat knob must be turned until it aligns with the “asterisk” icon and at the same time pressed in all the way.

Press the piezo ignition button several times to light the burner, but hold the thermostat knob for another 10-15 seconds . If the attempt is unsuccessful, repeat the procedure.

To service and repair the boiler, you should call a technician from the service center. Independent tampering with the structure will automatically void the warranty agreement.

IMPORTANT! The disadvantages of Aton boilers are common specific features of all such units.

Floor-standing single-circuit gas boilers Danko

Danko is a brand owned by PJSC Agroresurs, which is based in the Ukrainian city of Rivne.

The company creates heating boilers, guided by the principles of equipment availability, resistance to weather and climatic conditions, technological features of gas and water supply.

The main direction that allowed us to successfully promote our products on the market was the exclusion from the design of all minor and unused parts and assemblies, of which there are too many on European models.

This not only reduces the price, but also reduces the risk of boiler breakdowns or failures, which can become a very serious problem in winter. The company's products are aimed at the mass consumer; the boiler power level is optimal for use in small and medium-sized private homes.

There are non-volatile models that increase the reliability of the heating system, but require some changes in the configuration of the pipelines to ensure natural circulation of the coolant.

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

Types

Danko floor-standing boilers can be divided into two groups:

• Single-circuit. They are intended only for supplying coolant to the home heating system.
• Dual-circuit. Capable of preparing hot water for domestic needs simultaneously with the supply of coolant.

Most users believe that double-circuit boilers are much more convenient and efficient than single-circuit boilers. However, this statement is only true for families with a relatively small need for hot water.

The boiler's performance allows for limited hot water consumption; with large water consumption, the temperature will drop, which is inconvenient and uncomfortable for users. Therefore, many people prefer to install single-circuit models and connect an external indirect heating boiler to them.

This addition allows you to significantly increase DHW performance and stabilize the operating mode of the system as a whole.
