Floor-standing gas boiler Siberia: how it works, technical characteristics, as well as reviews and operating instructions

Autonomous heating systems demonstrate the greatest efficiency if they are based on gas boilers.

It is customary to classify the products of European companies as the highest quality and most reliable units, although there are serious complaints about them regarding the excessive sensitivity and fragility of some important components.

Recently, significant competition for these models has come from gas boilers from domestic manufacturers who have managed to find their own approach to creating heating equipment.

The driving idea was the exclusion of unreliable elements from the design, the rejection of all components without which the unit is capable of operating.

Let's consider the floor-standing gas boilers of the Russian] Siberia [/anchor], which have managed to provide a serious alternative to imported models.

Why does it go out?

The main reason should be considered a gas supply interruption.
If the valve on the gas pipe is closed, or the pressure in the network is lost, the burner will go out. First of all, it is necessary to determine how much the gas pressure corresponds to the operating values. In addition, external influence factors are possible.

The burner flame largely depends on the room conditions and the presence of draft in the smoke removal system.

If there are drafts in the room, the draft may be weakened or completely disappear. then the combustion mode changes sharply and the flame goes out. Another possible reason is the occurrence of reverse draft, which may be caused by strong gusts of wind or drafts in the building.

Recently, Siberia gas boilers have been gaining increasing popularity and respect among consumers. This is facilitated by the presence of such significant advantages as:

14. Thoughtful development taking into account the harsh climate conditions of our country and the characteristics of gas and water supply, an ideal ratio of quality and price.

Structure of a floor-standing boiler The device consists of the following main parts: heat exchanger, cover, gas exhaust device, walls, pilot burner, main burner, frame, gas block. The automation of the Siberia boiler provides: stabilization of the gas pressure on the main burner, maintenance of the set water temperature, turning on the main burner when there is a flame on the ignition burner, turning off the device when the ignition burner goes out, in the absence of vacuum in the chimney.

Design of the Siberia apparatus:

1 gas outlet; 9 ignition burner (pilot burner), 2 heat exchanger; 10 thermometer; 3 main burner; 11 cover; 4 gas valve; 12 side wall left / right; 5 cover with piezo ignition; 13 panel; 6 thermocouple; 14 anterior wall; 7 traction sensor; 15 frame; 8 thermal breaker; 16 thermostat indicator knob (magnetic valve button). Technical characteristics of gas floor-standing boilers Siberia

Who is the manufacturer

The Siberia trademark belongs to the management of Rostovgazoappart JSC. The company is located in Rostov-on-Don and is the most powerful representative of the domestic boiler industry in the group of household installations. In addition to Siberia boilers, the company produces a relatively new model range of RGA boiler units and the famous AOGV models.

The company was registered in 2002 and operates on the basis of an enterprise that produced its first AOGV-80 boiler in 1959.

All this indicates that Siberia has extensive practical experience in the production of inexpensive gas boiler equipment, which has been in deserved demand for six decades.

In practice, Siberia gas boilers have proven themselves to be high-quality and efficient devices, fully adapted to the unstable conditions of Russian gas networks, as well as the poor quality of the source water.

Often in consumer homes there are quite often budget modifications of units of this brand with steel heat exchangers that have worked for more than 10 years, despite the fact that such devices are considered not durable because they are susceptible to corrosion damage.

Types of devices

All single-circuit and double-circuit AGVs produced by Zhukovsky have three main varieties, which allow customers to choose a heating column depending on their available budget:

1. “Economy” modification - has a set of equipment necessary only for safe operation: domestic automation, temperature sensor, heat exchanger.
2. The “Standard” variation is also capable of modulating the burner flame, is controlled by a foreign control system, and can turn off when overheated, preventing damage.
3. The Comfort boiler complex is distinguished by the presence of a remote control unit, technology for maintaining the set temperature, and a room thermostat.

Heater parameters

The high efficiency of the AOGV - up to 92% - means that the installation of this equipment will bring maximum heating efficiency, and this is due to the original design of the jacket. Boilers can operate in heating systems with forced or natural circulation of coolant, provided that the pressure in the system is at least 1.4 Atm. Such conditions can ensure a liquid temperature of +40/+90C.

The disadvantage of this equipment can be considered to be too much power - even the lowest-power boiler produced by the Zhukovsky plant is designed to heat an area of ​​at least 200 m2, which means that in small houses its installation will be impractical and costly.

The burner in any modification and brand of boiler is made of stainless steel, so its durability is guaranteed. The jacket for hot water supply is made of copper, the body of the unit is coated with polymer or powder paint. Standard automation has temperature sensors and regulators to control the temperature of the coolant and prevent overheating of the boiler. The package also includes a thermocouple that controls gas flow and an air flow stabilizer, which serves to compensate for differences in air pressure during gusts of wind, and shuts off the gas in calm weather. Certificate of conformity for gas boiler AOGB

Single-circuit unit AOGV - design and dimensions

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.

Special features of the automatic system

As mentioned above, all products are automated and have a number of special features:

• The Italian Eurosit system controls the temperature;
• The automated system has a piezoelectric ignition function;
• Automation blocks make it easy to control the system;
• Mechanism of draft and flame control;
• The automatic system optimally consumes gas through the optimal choice of burner function;
• No need to control the process of the combination valve;

All systems are independent of energy, so there is no need to connect to the electrical network, and this is very important for Russia. Constant network failures disable all heating systems

Burner: basic operating functions

The Siberia heating system burner differs from its competitors in its operating features:

• The system is made of stainless steel, so even at low gas pressure there is no burnout.
• The burner is made in Italy.
• The system is made from environmentally friendly materials, so there are no harmful substances in the exhaust gases.
• The burner is very easy to use. You don't need any skill to replace or clean the system.
• At the time of replacing the igniter and the main part of the burner, the system runs on liquid fuel.

A few words about the power that each system has its own. To figure out how much power is required for an area, you can calculate it - take 10 square meters. m per 1 kilowatt. This calculation says that the system will work to its maximum, so add 0.3 to the resulting figure. If you need to warm up a room of 100 sq. m., then you better choose the 11th model Siberia. Moreover, when choosing a heating system, you need to choose design features - material, location, finish. For less insulated rooms, you need to calculate 1.5–2 kW per 10 square meters. m., for warm rooms - 0.5–0.7 kW.

If you want to use the Siberia boiler not only for heating, but also for supplying hot water, then it is better to buy boilers with the letter name K. If you buy the boiler model K, then such a system can provide all the hot water needs for several people. If more than three people will use hot water, then you need to buy a powerful boiler.

How much space is needed to install the boiler?

wall and floor heating systems can be used

The boiler room may not be heated

It is also important to consider that more powerful Siberia models make noise during operation. Some manufacturers produce powerful floor systems with excellent heat and sound insulation, which are installed outside the boiler room - in the hallway or kitchen

Additional details of the system are:

Additional details of the system are:

• Cranes;
• Expansion tank.

How to save on heating?

Without the slightest loss in comfort, you can reduce fuel costs by 10%. Especially if you have a private house and you are going to carry out major renovations. The initial costs can be recouped even with basic tariffs, and the price of fuel will rise. Your invested money will pay off even faster.

The very first thing you can do is reduce the heat loss of the building. This is a whole range of works, installation of doors and windows, insulation of walls

After all the work has been carried out, thermal monitoring must be performed: it is important to check that heat does not penetrate through the cracks. There are special companies that check losses using thermal imagers

And the owner of a private house can purchase a remote thermometer

It is also very important to choose a boiler based on power and positive reviews. The more square meters you need to heat, the more carefully you need to pay attention to the heat calculation. And the owner of a private house can purchase a remote thermometer

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.

Main advantages

According to the manufacturer, Siberia gas floor-standing boilers are a new generation of heating units designed to provide heating and hot water supply to the home. Compared to imported competitors, boilers of this brand have the following advantages:

• A wide range of models that can satisfy any consumer demand.
• Automated control system, which ensures ease and safety of use.
• Economical.
• Trouble-free operation even in the harshest operating conditions.
• Availability of service support.
• Affordable price.

Now, analyze each point of the above advantages in more detail, because only the reliability of the facts will allow the domestic consumer to consider the equipment of this brand as a candidate for purchase.

Installation rules

In order to create an autonomous heating system and install equipment, you must have a project and permits that are prescribed by the gas company. According to the manufacturer's requirements, the installation of Siberia floor-standing boilers must be carried out in accordance with SNiP standards and the requirements of GOST and SanPin, only by certified specialists who have permission to conduct such activities.

After you buy the equipment and have the permit in hand, you need to take care of additional devices. You need to purchase an expansion tank, a circulation pump, which is responsible for the forced movement of the coolant along the heating circuit. This equipment must be purchased separately, because It is not included in the boiler package.

The next stage is preparing the boiler room. Floor-standing boilers can be installed in a kitchen or in a specially designated non-residential premises that has a supply and exhaust ventilation system and a waste gas removal system. Utilities must be installed in the firebox.

Next, we pay attention to the location of the boiler unit - you need to choose an area near fireproof walls. Be sure to place the floor heating device on the foundation.

You can connect the pipeline and heating circuit yourself, without the help of specialists. Gas industry employees must connect the installation to the gas main.

Gas boilers from Siberia

Siberia boilers are the brainchild of Rostovgazoapparat CJSC. The company produces a wide range of heating and water heating equipment; installations produced under the Siberia brand are far from the only models in the company’s arsenal.

The main advantage, which determines stable demand and high-quality operation of boilers, is a deep knowledge of the conditions and operating features of heating equipment in the countries of the former USSR.

The manufacturer has eliminated the most problematic areas in the design, creating energy-independent units capable of operating in the most difficult conditions. This advantage can only be truly appreciated by residents of Russia who have an understanding of winter frosts and the danger of being left without heating.

The company produces units that are optimally suited for use in small and medium-sized private houses, of which the vast majority are in our country. Low gas consumption and active use of natural physical processes make it possible to increase efficiency and simplify the design of units.

All Siberia units are floor-mounted. This makes it possible not to load the walls in residential premises and expands installation possibilities - floor-standing boilers can be placed anywhere, unlike wall-mounted structures.

Since the units are non-volatile, the type of gas burner is the same for all - open (atmospheric) type elements with natural smoke removal are installed (a conventional stove-type draft is used). This circumstance puts forward some requirements for the room - it is necessary to ensure high-quality ventilation and eliminate drafts.

The circulation of the coolant is also natural by default, which creates the need for proper installation of the heating system in compliance with the required slope of the pipelines.

However, it is possible to install an external circulation pump, which increases the speed of movement of the heating agent and significantly increases the overall efficiency of the boiler.

There are single- and double-circuit models. The former are intended only for preparing coolant in the heating circuit, the latter simultaneously heat batteries and hot water for household needs.

The second type of design is more preferable in a private home, but the gas consumption of such boilers is slightly increased.

Product advantages

Gas boilers "Siberia" have the following advantages:

• Almost complete independence of ignition from the electrical network, since it is carried out using piezoelectric elements.
• High quality equipment.
• Ease of use.
• Long service life.
• Great looks.
• Variety of models.
• The different power of boilers makes it possible to choose the appropriate option.
• Automatic control. Thanks to this, the operation of the product is completely safe.
• Low fuel consumption.
• It is possible to purchase models with which you can additionally heat water.
• Burner resistance to high temperatures. Thanks to the stainless material that has undergone special treatment, you don’t have to worry about premature burnout of the element.
• High structural strength.
• Some models provide hot water to several points of intake at once.
• Acceptable cost: from 15,600 to 24,000 rubles.

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.

What to look for when choosing?

Before purchasing a dual-circuit model, you should pay attention to five important indicators:

Combustion chamber type

There are devices with an open and closed combustion chamber. Appliances with an open chamber take air from the room, and combustion products are discharged through the chimney. For safety reasons, such a chimney must be at least 4 m in height. Since this consumes oxygen from the room, ventilation in such a house must be well organized.

With closed combustion, air is taken from the street, and combustion products are discharged outside at this moment. Thus, the oxygen in the room does not burn and the overall atmosphere is much more favorable. Models with a closed chamber are suitable for those who have poor ventilation in their home. They can also be installed in the kitchen or bathroom. Devices with a closed combustion chamber are the only possible option for apartment buildings.

Boiler type

There are classic (convection) and condensation devices.

Classic wall-mounted gas boilers with two circuits, the 2020 rating of which will be given below, generate heat only by burning gas. On average, their efficiency ranges from 85 to 95%.

Condensing appliances generate additional heat by condensing water vapor that is produced naturally during the combustion process. Thanks to this, the boiler efficiency increases and can range from 100 to 110%. Taking this into account, the condensing model can reduce gas consumption by 10 - 15%. This savings will be especially noticeable when using heated floors. If you really want to save on heating and water heating, then take a condensing model. Such models will definitely be included in our rating of wall-mounted double-circuit gas boilers in terms of reliability.

Heat exchanger material

The heat exchanger of the device can be made of the following materials:

• Cast iron. Used in the cheapest models. It generates heat quite well, but the efficiency usually does not exceed 90%. Boilers with cast iron heat exchangers are heavier and bulkier, which complicates their installation.
• Stainless steel. Suitable for budget and middle class. Stainless steel is quite durable and can be easily repaired if necessary. However, heat transfer is less than that of copper.
• Copper. Copper heat exchangers are installed in mid- and expensive-class models. They are durable and dissipate heat well.

If you want to take a classic model and are going to install it yourself, take it with a stainless heat exchanger. For underfloor heating and hot water supply, we recommend choosing a condensing type device with a copper heat exchanger.

Boiler power

On average, 1 kW of device power can heat about 8 m2 of area. Divide the total area you need to heat by 8 and get the required power. Add 1 kW for water heating. If you want to more accurately calculate the power of the device, use the formula that we provided for single-circuit boilers.

Availability of built-in boiler

A separate type of double-circuit boilers can be additionally equipped with a boiler for heating and, most importantly, storing water. Sometimes it is very convenient to have such a boiler, since if there is a strong drop in pressure in the pipeline, the boiler may simply not heat the water, but the water in the boiler will always be hot. Purchasing a model with a built-in boiler makes sense only in cases where there is a frequent drop in pressure in the city water supply. Otherwise, it's a waste of money.

How to choose the right equipment?

The Siberia floor-standing gas boiler (you have already read the reviews) is very efficient and economical. However, you need to choose exactly the option that is suitable for your structure. The following parameters should be taken into account:

1. Device power. The higher it is, the larger the area it can heat. Naturally, the more power, the more fuel you will need. This parameter is always specified in the model name. For example, Siberia-11 has a power of 11.6 kW.
2. The size of the heated room. It can be found in the technical plan of the house. Calculating the power of the device is not difficult. For every 10 sq. m of area requires 1 kW of energy. However, the equipment should not be used to its limits to reduce the likelihood of wear on its parts. Therefore, it is better to increase the resulting power result by a third.
3. Climatic conditions.
4. Decorating the house. This parameter is also of great importance. For example, you can use facing material with additional insulation.
5. Availability or need for hot water supply.
6. Device type. If you want to install equipment in an apartment, it is better to give preference to wall-mounted models. For the home, the floor option will be the best.
7. Heat exchanger type. Experts advise giving preference to a cast iron product, as it is stronger and more durable.

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.

PLEASE ATTENTION!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.

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

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.

Choosing the right boiler

The most important characteristic that influences the choice of a floor-standing boiler is the power, which must correspond to the area of ​​the heated room. The calculation is done in specialized organizations that charge quite large sums for their services. In fact, you can estimate how much power of a heat generator is needed to heat a particular room on your own without complex calculations: to heat a 10 m2 room you need 1 kW of boiler plant power. The formula is correct for rooms with ceiling heights of up to 3 m. As practice has shown, for normal operation of the boiler unit, you need to add 30% to the resulting value.

Note! For poorly insulated rooms, the power of the boiler installation should be calculated: 2 kW per 10 m2 of area. For warm buildings located in the southern regions of our vastness, this figure is 0.5 (0.7) kW/10 m2

The second characteristic that you should pay attention to when choosing a floor-standing boiler is the number of circuits. If you want to use the installation not only for heating the room, but also to obtain hot water for household needs, then pay attention to dual-circuit models

They are designated by the letter “K”. Depending on the performance, each such boiler can produce a certain amount of hot water per unit of time.

At a water temperature of 35°C, the nominal flow rate is:

• 11 K – 3.8 l/min;
• 17K – 5.5 l/min;
• 23K – 7 l/min;
• 29K – 8 l/min.

The third selection criterion is the heat exchanger material. Above we indicated all the advantages and disadvantages of devices with steel and cast iron heat exchangers.

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.

• 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.

Advantages and disadvantages of the model

The advantages of Zhukovsky AOGV 23 boilers are:

• Reliability, simplicity of design.
• Independence from the power supply system.
• Simple and intuitive controls.
• Designed for use in Russian conditions.
• Designed to work in harsh climatic conditions.
• The service life is 14 years (or more).
• The cost of boilers is much lower than that of European analogues.

The disadvantages of the units should be considered:

• The heat exchanger of the units is made of steel, which is inferior in thermal conductivity to cast iron.
• The appearance of the boilers is inferior to European models.
• The mechanical automation of the boiler is quite weak.
• The dimensions and weight of the unit require installation in a separate room.

NOTE!

Most of the shortcomings are, to one degree or another, common to all atmospheric models, so they can be attributed to a specific design feature.

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.

The most common problems and breakdowns

It is clear that there is no perfect equipment and it breaks down or does not work as it should. In most cases there are specific reasons for this. Based on the operating experience of Siberia boilers, we can identify several characteristic problems that owners often encounter:

• Low heating of water for domestic hot water supply by Siberia double-circuit floor-standing boilers. There's nothing you can do about it - it's not their strong point. If you look at the technical specifications, the maximum hot water flow is very small. And this is at normal gas pressure. If the pressure is low (which usually happens in cold weather), then the water will be slightly warm.
• The water at the boiler outlet does not heat up to the stated 90°C (if you turn the regulator even to the very last, 7th position). There are several possible reasons. The first is low gas pressure. When the pressure drops below 130 mm. water the column's power decreases proportionally. When you call the gas service (they are responsible for the nominal pressure), ask them to clean the inlet filter. If it is clogged, the pressure will be low. The second possible reason is a burner clogged with soot and dust. It needs to be cleaned once a year. If this is not done, the efficiency decreases and the Siberia boiler heats worse.
• The pilot burner does not ignite the working burner. Again, there may be several reasons. And the first is low gas pressure in the pipe. But this time it is below 50mm. water pillar At this pressure the boiler does not start. The second reason is a clogged gas valve. The third is a smoked burner. In all cases, we clean the valve and/or burner. Fourth, the thermocouple sensor is located too far away (you can see it visually, if it doesn’t reach the flame, that’s the reason). In this case, you need to loosen the thermocouple mounting nut and move the contacts a little closer. Fifth - weak traction.
• After a summer of inactivity, it is difficult to start the boiler. During downtime, air collects in the gas supply pipe. Until it is “corroded”, it will not be possible to light the boiler. When igniting for the first time, open the window/vent and monitor your health. Take a break between launch trials. During this time, the burner will be ventilated and the Siberia floor-standing gas boiler will start up faster.

As you can see, there are a lot of problems, but most of them are related to the peculiarities of the work of public utilities in our country. Of course, there are reasons in the equipment. But this is a small part of the total number of cases of non-working equipment. In order for the Siberia floor-standing gas boiler to work without problems, it is worth fulfilling all installation requirements and carrying out regular maintenance.

User manual

Operating Siberia boilers is not difficult at all . The owner’s only task is to maintain the cleanliness of the unit and the absence of soot, soot or ash inside the unit. Changing the mode is done by turning the knob to the desired position.

In order to light the boiler, you need to press the handle, pushing it all the way, while simultaneously pressing the piezo ignition button.

Hold in this position for some time (up to 1 minute) until a flame appears on the pilot burner.

Then the control knob is switched to the desired operating mode, which will cause the flame on the main burner to light up and heating of the coolant will begin.

The system is filled with water with the make-up tap open. The process lasts until water flows from the signal pipe, after which the tap is closed.
