Characteristics of Siberia gas boilers

Siberia boilers have excellent technical characteristics. They appeared on world markets quite recently, but due to their original manufacturing technology they have already managed to outperform most of their competitors.

Siberia boilers have high performance and excellent characteristics. In addition, one of their main advantages is complete independence from the availability of electricity.

Technical characteristics of Siberia boilers:

The heat exchange tanks of such boilers are of very high quality and durable, thanks to the automatic welding of their parts. They can be cast iron or steel. The former have an impressive service life, the latter quickly heat up the coolant.
Siberia boilers have two circuits. Coolant flows through one, and the other is responsible for heating water for domestic needs.
Such devices have a thermal insulation layer, making their use safer. This material is used in the rocket industry.
The Italian Eurosit system is responsible for controlling the temperature in such boilers.
The system of such boilers is fully automated. It has electric piezo ignition.
Also in Siberia boilers there is draft and flame control;
The burner function is selected by the automatic system itself. Thanks to this, the device consumes gas at an optimal level.
Due to the fact that the boilers of this manufacturer are made of steel, they do not burn out even at maximum temperatures.
All elements of the product are made of high-quality and safe materials. Therefore, when gas burns, environmentally harmful impurities are not released into the atmosphere.
The burner is easy to use. You can clean and replace system elements even without special skills.
The system can operate on liquid fuel. This ability will be useful to you when replacing the igniter and the main part of the boiler.

As you can see, the technological characteristics of such boilers are at their best. The manufacturer has made sure that its products not only meet, but also exceed all international standards.

What functions does it have?

The main function of the unit is to heat the coolant for the heating circuit of a private house or other premises.

Additional functions of the boiler are:

Thermometer providing visual control of coolant temperature.
Piezo ignition system.
The presence of a two-stage burner, pilot (pilot) and main.
Availability of gas, flame and draft control.

All components and blocks of the boiler are conveniently located and allow for easy maintenance or repair.

IMPORTANT! It is not recommended to do independent work or repair the unit, especially if the warranty period has not yet expired. You should use the services of technicians from service workshops.

The best and most famous models: characteristics and prices

Classic floor-standing boilers Siberia

Classic, inexpensive and most popular boilers with a steel heat exchanger. They are distinguished by their compact size, heat exchanger steel thickness of 4 mm, reliability and reasonable price. Efficiency is 90%, gas consumption of the 11.6 kW model is only 1.18 m3/hour. Available in 11, 17, 23, 29 and 35 kW versions. There are also double-circuit models; they come with the prefix “K” (for example, Siberia 11K) and cost only 5-15% more than single-circuit ones.

Otherwise, after more than 12 years of operating experience, there are practically no serious service complaints; the model is considered the most successful and most reliable of domestic gas boilers. It has almost all the previously described disadvantages - sensitivity to clogging, noisy ignition

Please note that the maximum permissible operating pressure is only 1 bar, so it is not recommended to use the model in closed systems, where the operating pressure is usually 1.5-2 bar

Cost: 19,800-26,000 rubles.

KCHGO series

One of the best Siberia gas boilers for heating a private home. This is a larger and heavier model with a durable cast iron heat exchanger. Cast iron is practically not subject to corrosion, so such heat exchangers last 30 years or more, although they are much more expensive. Unlike the previous model, the permissible operating pressure is now 3 bar, which allows the boiler to be used in any domestic closed heating systems with forced circulation of coolant. Available in 16, 25, 40, 50 kW versions.

The burner and automation of the boiler are still the same - the famous Italian EuroSit and Polidoro, so the gas consumption remained at the same level - 1.7 m3/hour for the 16 kW model. Otherwise, everything is the same as with classic steel floorplates. A significant drawback is the lack of dual-circuit versions. Prices for cast iron models, although quite high, are much lower than foreign analogues and are among the lowest among domestic ones

Cost: 33,900 – 62,000 rubles.

Top Line Series

A mounted model, the body of which already contains all the necessary modules of the heating system (expansion tank, circulation pump, safety group, etc.). It is distinguished by the presence of a smoothly modulated burner, which is reflected in the maximum gas consumption - 2.65 m3/hour with a power of 24 kW. The copper heat exchanger is more resistant to corrosion than steel and more thermally conductive. But in dual-circuit models it is bithermic (double), which means almost zero results when washing it and vulnerability to scale accumulation. Therefore, it is imperative to use soft purified water as a coolant and change it as rarely as possible.

Cost: 21,500-26,000 rubles.

Advantages and disadvantages

The advantages of Siberia floor-standing boilers are:

Simplicity of design, reliability and reliability.
Lack of expensive electronics.
Complete energy independence of the units.
Compact, small size and weight.
Low gas consumption.
The prices of Siberia boilers are approximately half that of their European counterparts.

Flaws:

The complexity of ignition, requiring a certain sequence of actions.
For maximum efficiency, an external circulation pump is often needed.
Natural draft is unstable and highly susceptible to external influences - drafts, gusts of wind, weather changes negatively affect the smoke removal system.
The need to obtain permission from gas workers for installation.

IMPORTANT! The disadvantages can be considered design features, since they are present not only in Siberia (Siberia) boilers, but also in all non-volatile units without exception.

Equipment installation

Equipment installation must be carried out by a specialist. To do this, you will additionally need to obtain permission to install:

Registration of permission;
The gap between the wall and the equipment must be at least 3 cm;
For a floor-standing unit, you will need to prepare a foundation;
To prevent gas leakage, all connections must be carefully insulated;
The boiler should be started up for the first time by a specialist;
The company representative must provide the equipment with a warranty upon first start-up;
If you connect an electric boiler, you will need to install the electrical network and water supply;
When connecting heaters that are not volatile, additional equipment will need to be installed separately;
If you connect it to the network using the “cascade” principle, you can increase the power several times. Thus, it is possible to connect all types of boilers;
A piezoelectric element is used for ignition;
Initially, the igniter lights, and then the main burner.

If condensation appears on the heat exchanger during the first start-up, this is not a problem. When the unit heats up, it will disappear.

Possible malfunctions of the Siberia boiler and methods for eliminating them

If the panel fuse is damaged, it can be replaced.
If the room thermostat is set to a lower temperature or the timer is off, you need to adjust the settings.
If the gas does not correspond to the specified data, then you need to contact the service center.
The gas valve has been found to be defective and needs to be replaced.
If the fan of the boiler with a closed gas chamber has stopped and there is power, then it needs to be replaced.
The relay setting is out of order - replace it.
Tubes are clogged - clean.
Broken ignition electrode - replace.
The electrode is installed incorrectly - install correctly.
Defective ignition device - replace the device with the help of a specialist.
Air in the pipes is blocking the burner - ignite several times in a row.
Incorrect polarity of the power line can also block the burner - check the polarity and, if necessary, connect correctly.
The monitoring electrode is not connected - contact service.
If the flame is of an unusual color or height, then you need to adjust the gas supply.

Main components of the Siberia gas boiler

Model overview

The manufacturer produces products in three series: premium, comfort and economy:

The first series of gas boilers are Premium Topline-24 models, designed for use in small buildings, and the presence of a second circuit in them makes it possible to heat water. The main feature of such models is the presence of electronic ignition of the burner. Moreover, ionization control of the flame and exhaust gases is carried out, and a function provides protection against scale. The boilers have high efficiency (90%).
The second comfort series includes several models: Comfort Serbia 50, 40, 35, 29, 23. Their collection includes devices with both two and one circuit and heat large areas of premises. The first model has the ability to heat up to 8 liters of liquid in one minute. This series produces floor-standing boilers; their designs have a circular pump that prevents the heat exchangers from overheating.
The third series of Econom Siberia boilers. It appeared on market shelves in 2005 and includes 4 models. The difference between these samples lies in the contours and power (17.6 and 11.6 kW). If the letter “K” appears in a line of this type, there are two contours. High-quality atmospheric burner made of high-alloy steel from an Italian manufacturer. Automatic protection can be American (Honeywell) or Italian (Eurosite). If the equipment is reconfigured, it can use liquefied gas, which makes this series an indispensable unit during an emergency in gas pipeline systems. The body of the units is painted with special enamel, which gives the structure a modern look and protects it from chips and scratches.
All models from Rostovgazoopparat are combined by installation method - on the floor and have standard height (85 cm) and depth (65 cm), width can be different.

Device Features

So, Siberia gas boilers have the following operational features:

The size of the flame is adjusted automatically, and this is done very smoothly.
The device has a very high level of efficiency - up to 90%.
The device is capable of heating rooms whose area ranges from 100 to 500 square meters. m.
The heat exchanger can be open or closed, it all depends on the model of the device.
The temperature of water and heating is regulated separately, which allows you to use the Siberia gas heating boiler as a boiler in the summer. The heating system remains switched off.
Availability of additional functions: anti-blocking of the circulation pump, resistance to contamination and freezing.

Technical characteristics of Siberia boilers

Each Siberia gas boiler has fairly high performance characteristics, which are on par with those of the most famous foreign products.

If we talk about the advantages and disadvantages of the device of the brand in question compared to analogues, then we can highlight the following qualities:

High strength and reliability of the heat exchanger tank, which is achieved through the use of high-quality materials and automatic welding. Choosing a boiler equipped with a steel heat exchanger will allow you to achieve the highest possible efficiency. Heat exchangers made of cast iron are not as efficient, but they can last more than 25 years.
The Siberia double-circuit gas boiler provides not only heating of the room, but also supplying residents with hot water. Boilers of this brand use flow-through copper circuits.
Heating equipment of the brand in question is suitable for use in systems with forced and natural circulation of coolant.
The design of Siberia boilers includes high-quality thermal insulation materials, due to which high fire safety is achieved and users are protected from burns.
Each Siberia gas heating boiler is very easy to install, easy to maintain and does not create the slightest problem during operation.

It is also worth considering the features of EUROSIT automation, which you should know about before purchasing a boiler:

Possibility of precise temperature adjustment and stable support of a given mode;
Availability of piezoelectric ignition;
Quite convenient arrangement of automation units, which provides simple control of the system;
Availability of a draft sensor and combustion intensity control;
The presence of several burner operating modes, which are selected automatically and allow you to optimize gas consumption;
The combination valve operates in fully automatic mode;
Automation does not require a connection to electricity, so the Siberia gas boiler will work even in any case.

It is also worth saying a few words about the burners used in the construction of boilers:

For the boilers in question, Siberia Worgas burners are used, which are manufactured in Italy;
For the manufacture of burners, stainless steel is used, which does not burn out even if the gas pressure is at a minimum level;
The burners are environmentally friendly, so they do not pose any danger to the environment or human health;
Operation of Siberia burners is simple, and replacing or cleaning them requires a minimum of knowledge and skills;
When replacing the igniter and the working element of the burner, the boiler can operate using liquefied gas from a cylinder as fuel.

Owner reviews

Siberia wall-mounted and floor-mounted gas boilers are well represented in the retail network; they are quite in demand among Russians and have proven themselves to be excellent in practice, about which there are quite a lot of responses on the Internet. They reflect how devices behave in practice, their advantages and disadvantages.

Some user reviews on the operation of Siberia boiler units:

A good quality, simple and reliable device. Almost nothing superfluous, everything you need, does not need to be connected to electrical networks. An excellent competitor to imported boilers, it provides excellent service, heating and comfort at a low cost.
Siberia gas boilers are a device for those who have a good understanding of their design and operating principle. Many users choose imported units loaded with sophisticated electronics, not realizing that they are paying exorbitant prices for features they will never need.
Need for constant cleaning. It is advisable to clean the boiler, burner device and piezo igniter every year. If there are blockages in the boiler modules, difficulties arise with ignition and the functioning of the automatic protection system.
Noisy operation of the piezo igniter of the burner device; clicks are excessively loud during ignition. Many users believe that the device must be placed in a separate room.

Installation rules

Important! Creating an autonomous heating system and installing equipment requires a project and permits signed by the gas company. At the request of the manufacturer, installation of the Siberia floor heat generator must be carried out in accordance with SNiP standards and the requirements of GOST and SanPiN, only by certified specialists authorized for this type of work

After obtaining permission and purchasing a boiler installation, additional equipment should be purchased: an expansion tank and a circulation pump that ensures forced movement of the coolant through the heating circuit. This equipment is not included in the delivery package.
Prepare the boiler room. Floor-standing boiler units of this brand can be installed in the kitchen or in a specially designated non-residential separate room, which is equipped with a supply and exhaust ventilation system and an exhaust gas removal system. Utilities must be connected to the furnace room.
Installation location. Installation of equipment on a foundation near fireproof walls is allowed. The gap between the device and the wall should not be less than 3 cm. For ease of maintenance and operation, it is necessary to provide at least 1 meter of free space in front of the boiler.

You can do the work on connecting the water supply and heating circuit yourself. The connection of the installation to the gas main must be carried out by representatives of the gas industry. And lastly, in order to correctly connect the Siberia floor-standing gas boiler, the manufacturer’s instructions must be followed in full.

AOGV Siberia – installation

The manufacturer regulates that the unit should be installed exclusively by employees of a specialized service company. The organization must have a license or permit to perform such types of work. After installing the Siberia AOGV and checking its functionality, the homeowner is instructed. The organization that performed the installation makes a note about the commissioning of the device in the warranty card.

The plant disclaims warranty obligations in case of independent installation of AOGV Siberia. The owner or other person, if he is not an employee of a service company, does not have the right to put notes in the product passport. The installed unit is subject to mandatory registration with the gas service of your locality.

Of course, it is better to install the boiler on a cement base, but if you have no alternative and you have to mount the unit on a wooden floor, then you should isolate the Siberia AOGV from the floor covering. This is best done using a steel sheet, having previously laid an asbestos sheet with a thickness of at least 3 mm on the flooring. For complete safety, the insulating “pie” should protrude 10 cm beyond the overall dimensions of the boiler.

The device can be installed in a gravity heating system with natural coolant movement. But you will get the best performance characteristics of the system by using a circulation pump to quickly move the coolant, which in turn will more efficiently release thermal energy through the radiator system. Also, in order to extend the service life of the Siberia AOGV and improve its performance characteristics, we recommend installing a water purification filter in front of the device.

Installation of the chimney AOGV Siberia

The pipe through which combustion products will be discharged should be made of corrosion-resistant material; it must be made non-flammable and sufficiently durable. It must withstand loads without loss of tightness and strength;
When selecting a chimney, make sure that its internal diameter corresponds to 125 mm;
The length of the gas outlet in the vertical section from the apparatus cannot be made longer than one meter;
The gas outlet pipe from the vertical section to the chimney should not be longer than two meters;
The gas exhaust section is installed at a slope of more than 2° in orientation to the junction with the chimney. In this case, the rule of no more than three turns should be observed;
The gas exhaust chimney is hermetically connected to the AOGV Siberia boiler.

Features of this brand at the moment

The manufacturer itself positions itself as a competitor to Slovenian gas units “Proterm”. This can be seen in some design and technological solutions, as well as in the adopted standard outlet openings for various purposes. Siberia, of course, generally loses to Proterm in power, build quality and efficiency, but very seriously all the “disadvantages” are covered by an affordable and more than acceptable price.

Due to the desire to comply with foreign analogues and the best domestic representatives of gas boiler equipment, the implementation of technical and design innovations has led to very great difficulty in setting up the boiler. That is, if previously any user could adjust the equipment to suit himself, now only a specialist can do this. True, we must pay tribute that after high-quality tuning, the boiler noticeably reduces energy consumption, while leaving thermal indicators unchanged. It should also be noted that another, to a certain extent, weak point of the Siberia boilers is the automation, or rather, some of the sensors included in its composition. This applies to:

draft sensor (this is a problem with all domestic boilers);
flame cutoff sensor (an unconfigured pilot burner often cuts off the pilot flame when the wind is strong enough, but the sensor does not manifest itself in any way and gas continues to flow to the burner.

In Fig. samples of Rostov heating equipment products are presented below, you can familiarize yourself with the technical characteristics of its basic model:

The Siberia boiler is presented below, compare the technical characteristics

Rules for using the equipment

So, heating equipment will last longer if you follow the operating rules:

You cannot turn on the unit if its burner is faulty or the chimney has not been cleaned.
The boiler body must be grounded.
If you want to use antifreeze instead of water as a coolant, then it must be certified. The liquid must not contain ethylene glycol.
Do not bring the water in the system to a boil (heat more than 95 degrees).
If the boiler is installed near a wall lined with flammable materials, it should be protected with a gasket made of steel or asbestos sheet.
You can turn on the equipment only after the system is filled with coolant.
It is imperative to clean the chimney, filters, check the tightness of connections, and flush the burner once a year.

Siberia floor-standing gas heating boilers are a domestic competitor to foreign devices, which can be bought cheaper and will last longer.

Currently, there are a large number of heat generators from different manufacturers on the heating equipment market, among which the leading positions are occupied by German and Italian boilers. However, domestic producers are not giving up their positions. In the article we will look at what the Siberia gas boiler is and note its main characteristics.

Main faults of Siberia

The simple design of these boilers does not cause serious malfunctions, especially when users carry out systematic maintenance of the main modules. For this reason, there is practically no interest in spare parts for Siberia gas floor equipment.

The most common operational failures are:

The piezo igniter or the main burner device does not light well. The most common cause of this failure is poor traction. A possible reason for the lack of combustion is a clogged wick or base burner.
The pilot burner goes out after 5-15 seconds. This failure indicates reverse draft in the chimney. The reason for this is often an incorrectly designed gas duct: it is too short or too long and there is no deflector.
The boiler unit does not raise the temperature of the heating water above 60 C. Most often, this occurs due to a clogged gas valve.
Software failure E01, it indicates the absence of a torch. This can happen when the gas tap is turned off, there is a significant pressure drop in the gas network or surges in the electrical network.
Failure E04 - pressure drop in the water system is less than 0.7 bar. As a rule, this is due to air locks, leaks, breakage of the expansion tank or safety relief valve.

Manufacturer of universal boilers

The Siberia representative office in Rostov-on-Don is Russia's largest manufacturer of the RGA and AOGV model ranges. The
well-known Siberia trade representative office, located in the city of Rostov-on-Don, is the largest Russian manufacturer of the RGA and AOGV model ranges. The company was registered in 2002, but the date of its birth is unofficially considered to be the beginning of factory production, opened in the middle of the last century. Already in 1959, the AOGV-80 model, which later became legendary, was released.

The history of the Sibir trademark indicates that this enterprise has extensive experience in the manufacture of gas equipment. This is confirmed by the ever-expanding demand for budget models, which differ from Western models in their simplicity of design and low fuel consumption. In this they differ significantly from more expensive products of the Russian brand Lemax, for example, or similar heating units from Ukraine.

How to choose a gas boiler

First you need to decide on its power. The larger the room, the more power the speaker will need.

For every 10 sq. m. needs 1 kW of energy. In order for the device to work longer, you should not purchase it one-on-one with the calculated power

It is better to take with a reserve of 1/3.

It is important to take into account climatic conditions, as well as the decoration of the house. If the house is insulated, then heat loss will be less

Accordingly, a less powerful boiler will do.

You also need to take into account what it is needed for. Only for heating or for the availability of hot water.

If the equipment will be installed in an apartment, it is recommended to use a wall-mounted speaker, and if in a house, then it is better to use a floor-standing speaker. But it still depends on preferences, and, of course, on the size of the heated area.

For long-term operation, the type of heat exchanger is important. If it is cast iron, then this is only a guarantee of durability.

What series and models of the company exist?

There are three model lines:

AOGV. Single-circuit floor models used only for space heating. They have 5 models with power from 11 to 35 kW. They are simply marked Siberia 11, Siberia 17, etc.
AKGV. Double-circuit units providing heating and hot water supply. They have the same power models, the marking contains the letter “K” (combined) - Siberia 17K, Siberia 23K, etc.

NOTE! Both groups (AOGV and AKGV) are equipped with a primary heat exchanger made of stainless steel. Double-circuit ones have a secondary plate heat exchanger for heating hot water.. KCHGO

Increased power models with cast iron heat exchanger. The power range is between 16-50 kW

KCHGO. Increased power models with cast iron heat exchanger. The power range is between 16-50 kW.

The power of the boiler determines the area that it is capable of heating: 11 kW - 110 m2, 35 kW - 350 m2, etc.

About Siberia boilers

These boilers are manufactured by NMK, one of the largest manufacturing companies in the field of heating devices in Russia. “Siberia” is considered one of the most popular devices among all manufactured analogues.

“Novosibirsk Metalworking Company” - this is how the well-known abbreviation “NMK” stands for. The company began its existence in 1995. The years of successful development were not in vain. Thanks to the correct approach to all stages of the production process, the company has managed to establish itself from the best side. The brand's products are distinguished by first-class quality, due to excellent materials, modern technologies and careful control of all stages of model creation.

A huge assortment allows us to please clients with any income. There are products on sale in different colors, sizes and purposes. There are stoves and high-quality greenhouses here. Boilers deserve special attention. These devices belong to boilers from the “solid fuel” section. They are represented by two series: “Hephaestus” and “KVO”.

There are five standard sizes of Siberia units: KVO 10,12,15,20 and 25 kW. The main material from which these devices are made is steel, which has good resistance to elevated temperatures. Cast iron is also sometimes used. As for Hephaestus, it is available in three versions: 15, 20 and 30 kW.

Manufacturer information

For ten years now, a company producing heating units has been mass-producing its products. Although its roots go back to 1888, when two factories merged. And 1959 was significant for the production of heating devices; the product was a prototype of modern AGV-80 models.

Over time, modifications were improved, and the AGV-120 model appeared in 1967, which was based on the old AGV-80 models. The production of both brands has survived to this day, which speaks of the reliability and quality of the product.

A well-known company is engaged in the production of boiler structures. She was awarded an Honorary Diploma during the presentation of the product at an international exhibition. And has been repeatedly awarded prizes for quality products.

The year 2005 was marked by the release of products under the Siberia brand. The developed modifications of this brand meet the quality, reliability and ease of use. Consumers actively use Siberia brand products.

Design

Looking at the Siberia units, you can see that they are simple classic boilers. The design includes a water jacket and, in fact, the boiler itself. “Siberian” boilers are quite compact, which allows them to be located in absolutely any part of the house.

If we consider the design in more detail, then we need to say a few words about the grate, transversely located beams, and the lid.

A grate is needed to achieve maximum effect. It helps to make the heat removal area larger.
The beams are installed on the paths of flue gases. They direct heat into the heating system.
The lid has holes where charcoal is usually placed.

Line of models

The Siberia floor-standing gas boiler is most often used for heating large buildings. However, you should consider all product lines of the presented manufacturer:

AKGV and AOGV. These devices are installed on the floor. Their power ranges from 11 to 35 kW. The heat exchangers in them are often made of carbon steel. AKGV models are double-circuit, and AOGV are single-circuit. The presented equipment is capable of heating rooms with an area of 125-400 square meters. m. At a heating temperature of 35 degrees, you can consume 3.8-8 liters of hot water per minute.
KCHGO. The line of these devices is distinguished by high power: 16, 25, 40 and 50 kW. Such boilers are intended for heating very large houses, industrial or warehouse premises. The heat exchanger in this equipment is made of cast iron.
Top Line. These are wall-mounted devices with a power of 24 kW. They are equipped with biometric copper heat exchangers. They are capable of serving several water intake points. Most often they are used in those houses whose area does not exceed 200 square meters. m.
Aqua. These devices are intended, rather, for heating water. Their power ranges from 18-23 kW. The speakers have piezoelectric or electronic ignition.

Design and principle of operation

The main idea used by the creators of Siberia is to develop a completely energy-independent floor-standing gas boiler Siberia. It can work in difficult situations without requiring electricity. This approach became correct, and the low cost of the units created great consumer demand.

The structure of Siberia. Photo source: mtbwn.us

The Siberia gas boiler is made with an open-type atmospheric burner, which places increased demands on air exchange in the room where it is located.

Smoke removal is carried out in a natural way; for this reason, drafts or a sudden change in air movement are dangerous, since they contribute to an emergency situation due to the separation of the gas flame from the burner or smoke in the room.

An internal highly efficient heat exchanger, made of steel or cast iron, makes it possible to heat water with an efficiency of 90%, which corresponds to the performance of many popular Western analogues.

Design of floor-standing gas boilers Siberia:

Internal heat exchanger of the heating circuit, for single-circuit devices.
Secondary heat exchanger for heating DHW, for dual-circuit devices.
Multifunctional three-way valve for adjusting coolant flows.
Set of gas elements: shut-off valve, torch combustion stabilizer, fine filter.
Automatic piezo ignition.
Gas burner device in the form of two burners - main and ignition.
Automatic regulation and protection system.

The basic functions of the Siberia gas boiler are performed by the burner device and heat exchangers, where the water coolant is heated. The heated water directly enters the three-way valve for single-circuit modifications or flows through the secondary boiler, heating the water for domestic hot water.

In the mixing unit, the coolant acquires the specified temperature and enters the heating circuit. The movement of streams occurs by gravity, under the influence of natural circulation of layers of water.

Similarly, using the natural circulation of air layers, smoke combustion products are discharged into the atmosphere.

Device

The main design elements of the Siberia 17 gas boiler are an open type burner combined with a steel heat exchanger.

Together they perform the main task - heating the coolant. At the exit from the heat exchanger, the liquid enters a three-way valve, where the colder “return” is mixed into the hot flow to obtain the desired temperature.

The prepared coolant flows by gravity into the heating circuit.

Water moves under the influence of convection currents, moving hot layers up and cold layers down.

Taking this into account, the system must be installed in compliance with the standard slope, ensuring coolant circulation.

If this is not possible, it is necessary to connect an external circulation pump, which will ensure more active flow movement. However, in this case, the energy independence of the boiler ceases.

Smoke removal also occurs naturally, using stove-type drafts. This is an important and crucial point, since weak draft will cause smoke in the premises and the impossibility of operating the boiler. Proper installation and connection of the chimney will help ensure the necessary conditions.

IMPORTANT! The connection and first start-up of the boiler must be carried out by employees of the guarantee organization.

The units are equipped with a steel heat exchanger, which is able to guarantee efficient heating of the coolant.

On sale you can find models that are equipped with a cast iron heat exchanger. It ensures the service life of the device up to 25 years or more. Siberia double-circuit boilers supply hot coolant to the heating system due to the fact that a copper circuit is installed inside. If necessary, you can use the equipment in a water supply system with forced and natural circulation. The described units are manufactured using a layer of thermal insulation. It eliminates injury and burns. The devices are manufactured using high-quality materials and are easy to maintain during operation.

Popular brands - how to choose the best option

Among the wide variety of boilers, German and Italian equipment takes the lead due to its high quality. Russian manufacturers offer high-quality equipment at a relatively low price. However, you need to figure out how the products of some companies differ from others, and which mounted gas boiler is better.

Bosch

This German company was founded in 1886 and has been supplying only high-quality products to the market throughout its history. Bosh equipment works flawlessly for 20 years, and with proper use, the service life increases significantly. The boilers of this company are equipped with a built-in self-diagnosis and automatic adjustment system. Therefore, when the flame in the burner goes out, the gas supply stops. Boilers can operate on natural or liquefied gas. For the manufacture of heat exchangers, copper coated with an oxide film is used, which prevents metal corrosion. The compactness and neat appearance of the equipment allows the boilers to be installed in niches or kitchen cabinets. Double-circuit heating gas boilers for a private home fit perfectly into any interior.

Viessmann

This German company supplies the market with single-circuit and double-circuit boilers. The modernized design of the chimney does not allow ice to form on its surface. The compact device is equipped with a membrane expansion tank with a volume of 6 and 10 liters. Distinctive characteristics of Visman equipment include high quality assembly and high performance.

Beretta

The quality of components and high power, over 24 kW, allow German Beretta boilers to stand out among similar products. The product range is represented by single-circuit and double-circuit boilers, as well as equipment that has a boiler included. The heating double-circuit boiler runs on natural gas, but if necessary, it can be connected to liquefied gas cylinders. The 60 liter boiler has a built-in expansion tank. The equipment can be operated even at fairly low temperatures.

Baxi

Gas heating boilers from the Italian company Baxi are fifth-generation appliances. They are equipped with atmospheric burners, which ensure silent operation of the equipment. A special feature of the boilers is a bithermic heat exchanger and a wide power range, 10-80 kW. In addition, all products have a compact size and high efficiency, up to 90%. Impeccable operation of the equipment is guaranteed for 7 years.

Korean-made boilers

The Korean company Daesung supplies the market with Arderia equipment, which can be used for both heating and hot water supply. Instant heating of water in the boiler occurs due to the presence of copper and steel heat exchangers. Protection against power surges is provided by a built-in voltage stabilizer, which allows normal operation at 150-280 V. In addition, Korean boilers are protected from overheating, freezing and gas leaks. The equipment can be controlled remotely, which tips the balance in their favor when choosing a gas wall-mounted boiler.

Domestic equipment

Russian gas boilers are represented by JSC Borinskoye. The company offers equipment capable of operating in a system with forced and natural coolant circulation. Unlike imported products, Russian equipment operates without being connected to a power supply network, which gives them many advantages. In addition, the boilers are characterized by high quality and long service life. The disadvantage of the equipment is the mandatory presence of a pump, thermostat and expansion tank when installed in a system with forced circulation.

Another domestic product is a wall-mounted double-circuit gas boiler for heating Danko’s apartment. This equipment can be used to heat rooms whose area does not exceed 140 m2. The advantage of boilers is explained by the presence of a sealed combustion chamber, a steel heat exchanger, piezoelectric ignition and micro-flare burners. The power of Danko boilers ranges from 7-15.5 kW, which is quite consistent with the area of small buildings.

The lineup

The Siberia line of floor-standing boilers includes nine models, of which five are designed only for heating, and four are designed for heating and domestic hot water supply.

Attention! The letter “K” in the designation indicates that the boiler has the ability to extract water for household needs. In other words, it is intended for heating and hot water supply at home

The power of the boilers varies from 11.6 kW to 35 kW, which is enough to heat rooms ranging from 100 to 350 m2. Below are the main technical characteristics of the lines of floor-standing gas boilers, AKGV and AOGV.

A feature of the boilers of this model range is the presence of a steel heat exchanger, which has high strength and reliability, and also ensures efficient heat transfer to the coolant.

Important! Steel is susceptible to corrosion. It is this fact that casts doubt on the long service life of a gas boiler with a steel heat exchanger

For heating large rooms, the manufacturer has provided a line of boilers with a cast iron heat exchanger KCHGO. The model range includes floor-standing boilers with a power from 16 to 50 kW. For clarity, we present a list of technical characteristics of this line of Siberia gas boilers.

Cast iron heat exchangers are not subject to corrosion and practically do not react to low quality coolant

However, the “innate” fragility of this material requires careful operation from the owner, which is to prevent sudden changes in coolant temperatures

Based on the foregoing, we can conclude that the range of Siberia floor-standing gas boilers is indeed quite large and capable of satisfying the demand of domestic consumers.

Execution options

Siberia gas boilers are available in the following modifications:

The Siberia gas floor-standing single-circuit boiler is equipped with a cast-iron heat exchanger, which provides high power to the unit. Based on the power of the heating device, it can be used to heat private houses and buildings with several floors;
The Siberia double-circuit floor-standing gas boiler has a steel radiator. The device is used both for heating and for supplying the premises with hot water for domestic needs;
The Siberia wall-mounted gas boiler is characterized by its light weight, compact size and high performance.

Let's look at the distinctive features of mounted units:

First of all, it is worth noting that such devices are very popular among users, because they are practical, small in size and have wide functionality;
bithermal radiator, made of copper;
the burner is made of alloy steel;
there is an anti-freeze function;
There is a liquid crystal display that displays all the information and error codes that appear during failures.

If you connect a room thermostat, you will reduce fuel consumption. Features of floor-standing boilers:

Available with two types of radiators: cast iron and steel. Double-circuit ones have a steel radiator and are connected to the hot water supply circuit. The Sit autocontrol unit includes:

modulation thermostat;
magnetic valve;
pressure stabilizing device;
gas filter;
thermoelectric device with a fire control sensor and piezo ignition.

Their advantages:

the use of such devices is highly economical;
have a reasonable price;
characterized by reliability and durability;
have a compact size;
non-volatile, that is, their operation does not require electrical energy;
wide range of products.

Siberia or Lemax: which is better

Floor-standing gas boilers have a similar, slightly more complex design, but similar automation and burners. The efficiency of almost the entire Lemax model range is also 90%, but gas consumption is on average 10% higher. For example, Lemax Premium-16 kW has a maximum gas consumption of 1.9 m3/hour. Lemax boilers are quieter, and even steel models are designed to operate in a circuit with a pressure of up to 3 bar. However, their cost is 10-20% more expensive.

Siberia is more reliable, more economical, simpler and cheaper. But it is deprived of the above-described advantages inherent in the Lemax model range. In general, both manufacturers are worthy of attention and it is not for nothing that they are sales leaders among domestic manufacturers of gas boilers.

Review of Lemax gas boilersThe most famous and widespread among domestic models

Features of Siberia gas boilers: review of floor-standing units

Siberia floor-standing appeared on the market not so long ago, but have already earned good reviews from customers and specialists.
The Siberia boiler is a product of the famous Russian enterprise “Rostovgazoapparat” (Rostov-on-Don), whose history dates back to the end of the 19th Century. This Rostov company became known thanks to the legendary AOGV gas boilers, which heated the private homes of millions of residents of the former USSR. But time does not stand still; all competitors on the market are constantly improving their products. Rostovgazoapparat also did not stand aside, presenting to the consumer a modern gas heating unit - the Siberia gas boiler.

We will talk about this device today, having examined in detail the double-circuit and single-circuit models with an atmospheric burner presented in stores, their technical characteristics, features and internal structure according to its operating instructions (passport).

Having analyzed all the parameters of the Siberia gas boiler 11, 17, 23, 29 and 35, we will leave our review based on the advantages and disadvantages of this device for heating a private home, and also watch a video about possible malfunctions: why it does not light up and does not heat the water.

Model range of Siberia boilers

On the domestic market, the Rostov enterprise is represented by two types of floor-standing gas boilers of the Siberia series:

— with a steel heat exchanger; — with a cast iron heat exchanger.

Boiler Siberia 11 with SIT automation

All boilers have a modern appearance, in contrast to the models of the “Soviet” AOGV series, the necessary set of functions and a reliable security system. All devices are completely energy-independent and operate at low gas pressure, i.e. adapted for Russian operating conditions.

In addition, the Rostovgazoapparat enterprise offers customers different types of its devices:

— single-circuit gas boilers Siberia, intended only for heating; - double-circuit gas boilers that already perform two useful functions: heating and hot water supply.

The most popular, judging by consumer reviews, are single-circuit models of Siberia boilers. They are produced in different capacities: 11, 17, 23, 29 and 35 kW. Only boilers with a steel heat exchanger are produced as double-circuit ones, and with a cast iron one - only for heating.

Siberia gas boilers with a cast iron heat exchanger are characterized by high reliability and long service life of the device, thanks to the material of its manufacture. They are produced with a nominal power of 16 to 50 kW, are capable of heating a room up to 500 m2, and are marked as follows:

— Siberia Ch16 (KCHGO 16); — Siberia Ch25 (KCHGO 25); — Siberia Ch40 (KCHGO 40); — Siberia Ch50 (KCHGO 50).

“H” is a cast iron boiler, and the number indicates the power of this heating apparatus. “KCHGO” is a cast iron gas heating boiler.

Floor-standing gas boilers Siberia

— Siberia 16E; — Siberia 25E; — Siberia 40E; — Siberia 50E.

Gas boiler Siberia: design and automation

Like most floor-standing gas boilers, heating devices of the Siberia brand consist of a housing, a heat exchanger for heating the coolant (water jacket), a gas burner and automation.

The Siberia gas boiler is equipped with a steel or cast iron heat exchanger, Italian SIT automatic equipment (gas valve, thermostat, piezo ignition and boiler safety system), a Polidoro gas burner made of stainless steel, as well as a layer of foil thermal insulation with basalt fiber.

Let's take a closer look at the internal structure of the Siberia single-circuit gas boiler according to the instruction diagram.

Siberia boiler design

Gas boiler Siberia: technical characteristics, dimensions, connection

The Siberia boiler has compact dimensions, and depending on the model, its dimensions are only 850/280/560 or 850/380/560 mm. The fittings for connecting to the heating system have a diameter: for a device with a power of 11 kW - 1 1/2′, for others - 2′.

The gas connection to the boiler is made using a bellows hose with a diameter of 3/4′, for a device with a power of 11 kW - 1/2′. And for domestic water - also 1/2′ for all dual-circuit models. Boiler chimney diameter: on Siberia 11 and 17 units - 125 mm, on more powerful models - 140 mm. Other technical characteristics, gas consumption and productivity are described in the table.

Siberia boiler: technical characteristics

— time-tested manufacturer; — compact dimensions; — modern Italian automatic equipment is installed on all models; — quiet operation; — efficiency of at least 90%; — wide model range; — reasonable price for the boiler and spare parts.

Disadvantages of Siberia boilers:

- low hot water productivity for dual-circuit models; — Russian assembly; — the network of service centers throughout the country is poorly developed.

So, we have examined Siberia floor-standing gas boilers , customer reviews of which are increasingly found on the Internet: on forums and stores. We reviewed the technical characteristics according to the instructions, features and internal structure of heating devices produced by the Rostovgazoapparat enterprise. We identified the main advantages and pointed out some disadvantages of Siberia boilers. Let's watch a video review from the buyer about the experience of using the device.

Despite the enormous popularity of foreign household appliances, the domestic industry also produces high-quality equipment. For example, Siberia gas boilers have many advantages and high quality. This equipment can be used to heat not only residential but also industrial premises.

Known faults of Siberia boilers

As mentioned earlier, the common simple design of floor-standing boilers does not imply serious damage, especially if regular maintenance of the main modules is carried out. Therefore, there is practically no demand for spare parts for Siberia boilers. Only occasionally there are cases of replacing the igniter or thermocouple (often the reason for its replacement is oxidized contacts, which can simply be cleaned with sandpaper).

Unlike service complaints, operating difficulties are more common. Most often, owners encounter the following phenomena:

+ The igniter or main burner does not light

Make sure that you light the boiler according to the algorithm described earlier. If you follow the instructions exactly, the most common cause is reverse thrust or no thrust at all. To check the presence of draft, hold a lit match to the window at the bottom of the boiler, on the burner module block: if the fire goes in the direction of the combustion chamber of the boiler, then everything is in order with the draft; if it remains unchanged or moves away from the boiler/goes out, it means there is not enough draft or the boiler is being blown by the wind. What to do if the gas boiler blows out in a strong wind

Another common cause is a clogged pilot or main burner. It is necessary to disassemble the boiler by removing the burner module and carefully clean the igniter first and then the burner. Be careful not to allow even the slightest scratches or deformations.

+ The igniter (wick) goes out

If the pilot burner lights up, but goes out after 5, 10 or 15 seconds, the problem is almost guaranteed to be backdraft. Check its presence with a lit match, as described in the previous case. The cause of backdraft in most cases is an incorrectly designed chimney: insufficient or excessive length, lack of a protective deflector, etc.

+ The boiler does not reach temperature (usually more than 60 degrees)

The most common cause is a clogged gas valve (on the gas supply line). Unscrew the gas pipeline nut in front of the boiler automation and carefully blow through the tube, as well as the mesh in it. If the temperature has not returned to normal, make sure that the boiler’s heating output is sufficient to replenish the heat loss in the house and that it is not operating at its maximum. For example, measure the gas consumption per hour of operation at maximum power and compare it with the factory indicators: if your consumption indicator is equal to or greater than the factory one, the boiler really does not have enough power.

+ Errors E01 and E04 for mounted boilers

Error E01 indicates the absence of flame. This can happen if the gas supply valve is closed, there is a pressure drop in the gas line or a short-term power outage (even for 1 second). Error E04 indicates a drop in pressure in the system below a critical point (0.7 bar). Most often this happens due to air locks, leaks, a malfunction of the expansion tank or relief valve. We have already described all possible causes of pressure drop in one of the previous articles.

AOGV Siberia inclusion

“EMK”, an electromagnetic valve of Rostovgazoapparat’s own design, is participating in the launch of the device. The following manipulations will be required:

Make sure that the heating system circuit and the unit itself are completely filled with coolant;
Don't forget to check your traction. A good vacuum draws in the flame, just place a match under the umbrella, position 5 in the figure;
Make sure that the water tap is closed;
Set the gas valve on the gas pipeline to the open position;
Set the gas valve of the main burner to the closed position, figure position 9;
Press the round key of the magnetic valve until it stops, bleed the air for two minutes, and then light the pilot burner. Hold the key pressed for about 1 minute to warm up the thermal cylinder;
After one minute, begin to smoothly release the magnetic valve button. If you did everything correctly, the AOGV Siberia pilot burner will remain burning without going out. In order for the thermocouple to be constantly hot and not give a signal to stop the gas supply, the direction of the flame from the igniter must fall on the thermal cylinder. If the flame misses, you should adjust the tube in the right direction;
Gradually, without sudden movements, open the gas valve of the main burner to half the full stroke (counterclockwise by 45°). As soon as the flame spreads across the entire plane of the burner, set the required flame value while continuing to manipulate the gas valve handle.
In the case when the actions taken did not lead to the main burner burning, and the pilot went out, re-ignition is performed no earlier than 5 minutes later. This requirement must be met in order to completely ventilate the firebox;
Set the size of the main burner fire to at least 2–3 cm, otherwise there is a possibility of self-extinguishing. The maximum flame height can be set to 7cm. If you set the flame higher, the flame will jump into the mixer and the process of soot formation in the burner and heat exchanger will start. In the absence of draft, the flame may jump out of the firebox; it is prohibited to operate the AOGV Siberia boiler in this condition. The combustion flame height values are set using the gas tap of the main burner on the automation unit.
Stopping the boiler operation is quite simple; to do this, you need to close the gas valve of the main burner and the gas valve on the supply line.

Advantages of AOGV Siberia and customer reviews

Long service life;
Due to the simple design, judging by the reviews, good reliability is noted;
Low price. AOGV Siberia boiler for 17 kW can be found for 22 thousand rubles;
You can save two times: on the cost of purchase and operation;

According to reviews from customers and owners, AOGV Zhukovsky is often compared with the AOGV Siberia boiler. AOGVs
of the Zhukovsky
Machine-Building Plant are more expensive, but they have Italian automation installed. The same applies to Lemax boilers, with which AOGV Siberia is also often compared.

Boilers have the same purpose, and in the end it all depends on your wallet. Perhaps a better decision would be to purchase a boiler from a manufacturer that has a specialized service center in your area. This way you will be under reliable protection.

Compliance with operating rules

The heater, like any other equipment, will last longer and be of better quality if you follow the established rules during use:

Do not turn on if the burner is faulty;
Do not use if the chimney is dirty;
The case must be grounded;
It is necessary to ensure that the water in the system does not reach a boil;
The boiler must be installed in a safe place to prevent the surrounding materials from catching fire;
Before turning it on, you should make sure that the system is full;
Maintenance should be carried out once a year:
Filter cleaning;
Burner flushing;
Checking the tightness of connections.
