Gas boilers Siberia for heating - single-circuit and double-circuit

European companies are considered recognized leaders in the production of heating equipment.

However, their products have considerable flaws, which are generated by the very approach to creating heating boilers.

Overload with electronics, an abundance of unused or unclaimed functions and other excesses increase the price, but significantly complicate the operation of the units.

Domestic manufacturers prefer a completely different approach to the production of gas boilers, relying on the reliability and unpretentiousness of their models.

Let's consider one of the Russian models of gas boilers - Siberia.

Floor-standing gas boilers Siberia

Siberia gas floor-standing boilers are produced by Rostovgazoapparat CJSC.
The brand was created on the basis of previously produced gas heating boilers, the design of which was modified, improved and optimized to the maximum. The main idea that the developers professed was to create a maximally independent unit capable of operating in difficult conditions and not requiring electricity .

For our country, this approach turned out to be the most correct, and the low cost of boilers immediately created stable demand.

The units all have an atmospheric (open) burner, which places increased demands on the organization of air exchange in the room where it is installed. Smoke removal occurs naturally, so drafts or sudden changes in air flow are unacceptable - they create a danger of flame failure or smoke in the room.

A heat exchanger made of cast iron or stainless steel allows heating of the coolant with high efficiency - efficiency is up to 90%.

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.

Types

According to the set of functions, Siberia boilers are divided into two large groups:

• Single-circuit . They provide only the preparation of coolant for the heating system.
• Dual-circuit . Capable of simultaneously heating coolant and hot water.

The first group has the simplest design, and the second has an additional heat exchanger.

The issue of heating hot water is solved simply - the hot coolant that has just left the heat exchanger enters the secondary one and transfers some of the thermal energy to the water.

This method does not require significant design complexity, which allows you not to increase the price and get maximum benefit from the operation of the unit.

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.

Design features and technical equipment

The design of boilers of this brand is practically no different from their imported counterparts, however, there are several points that the consumer should pay attention to.

1. The body of all models of Siberia floor-standing gas boilers is thermally insulated with foil-coated basalt insulation. This means that the manufacturer has minimized heat loss and taken care of the safe operation of its devices.
2. Siberia floor-standing gas heat generators use non-volatile automation with piezoelectric ignition and flame control, a magnetic valve and a modulating thermostat. A special feature of the automation is the presence of a gas pressure stabilizer, which makes the boiler safe for operation in conditions of frequent pressure changes in the gas main.
3. The burner used in the equipment of this brand is atmospheric and made of stainless steel.

It should be noted that the vital modules of Siberia gas boilers are not produced at the plant, but are purchased from Italian contractors. Eurosit automation is famous for its reliability and accuracy in maintaining the coolant temperature; Worgas burners are considered environmentally friendly equipment; When fuel is burned, there are no traces of nitrogen and carbon oxides in the exhaust gases.

Conclusion: the automation and technical equipment of Siberia boilers allows you to safely operate the equipment in conditions of power outages and gas pressure drops in the main line.

Fuel consumption

While examining the efficiency factor of Siberia floor-standing boilers, one pleasant fact emerged that some models can easily operate on both natural and liquefied gas. That is why both indicators should be cited for comparison. Let's consider the average model of a double-circuit floor-standing boiler Siberia in comparison with boilers of similar power from other brands.

• Siberia AKGV 17 K. Power 17.4 kW. Allows you to heat a room up to 200 m2. The nominal flow rate of natural gas is 1.76 m 3 /h; liquefied – 1.21 kg/h.
• The single-circuit floor-mounted gas heat generator Protherm Bear 20 KLOM has a power of 17 kW. The “passport” consumption of natural gas is 2m 3 /h; liquefied 1.6 kg/h.
• Aton Atmo AOGV-16E is a single-circuit boiler unit from Ukrainian partners. Productivity – 16 kW. The gas consumption declared by the manufacturer is 1.8 m 3 /h.
• Gas floor heat generator Wolf FNG-17 (Germany). Power 17 kW. Heating area – 136 m2. Consumption – 2 m 3 /h.

Peculiarities

The Siberia 17 model has the following overall dimensions - 280x850x560 mm (WxHxD), and the weight is 56 kg. Installed on the floor in compliance with all necessary distances from the nearest walls.

Operating principle and main parameters.

The convection type of device involves the generation of heat by combustion of gas, while the boiler operates on natural gas (methane, consumption 1.76 cubic meters per hour) and liquefied gas (propane-butane mixture, consumption 1.21 kg/hour).

Non-volatile operating principle

does not require connection to the electrical network and this is a plus, but usually, with this scheme, ignition must be started manually, and the coolant circulates naturally, i.e. without a pump. The main disadvantage of such boilers is the lack of algorithms and systems for saving electronic fuel, for example weather electronics.

Primary heat exchanger.

In the case of Siberia 17, steel is used, its advantages are budget cost, lightness and tolerance to shocks and deformations, disadvantages are a little more susceptible to corrosion, less durability, an approximate service life of 5-20 years, depending on the intensity of use.

Management and control

The Siberia 17 gas boiler is controlled mechanically, which means that the main parameters are adjusted only manually and, as a rule, there are few of them; there is no way to save fuel. The advantage is greater reliability than that of an electronic panel and cheaper repairs in case of breakdown.

Thermometer

necessary to control the temperature of the coolant in the boiler.

Protection systems

Gas control

- this useful burner function automatically stops the gas supply if the flame goes out for any reason.

Connection

• The size for connecting the gas pipe is 3/4″.
• To connect the heating circuit - 2″.

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.

What functions does it have?

The main function that the boiler performs is heating the coolant and supplying it to the heating circuit.

In addition, the boiler has the following capabilities:

• Determining the temperature of a liquid using a thermometer.
• Pressure control using a capillary action pressure gauge.
• Piezo ignition.
• Availability of mechanical sensors for controlling traction, gas pressure, flame.

The list of boiler functions is not as wide as that of imported models, but this does not prevent the device from performing its task efficiently.

IMPORTANT! The list of functions of the Siberia 23 boiler is quite modest, but this does not indicate the primitiveness of its design, but indicates the absence of unnecessary components and parts that complicate the work.

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.

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.

Advantages and disadvantages

The advantages of the single-circuit floor-standing boiler Siberia 17 should be considered:

• Reliability, stability.
• Silence.
• Energy independence.
• Simplicity of design and control.
• Unpretentiousness, all maintenance consists of cleaning and checking traction.
• Low cost.

The disadvantages of boilers can be considered:

• Lack of hot water heating function.
• Some difficulty starting the boiler.
• Lack of a display showing the current operating mode and other parameters.

NOTE!

The disadvantages of the model are due to its design and are typical for all similar units.

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 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:

1. Internal heat exchanger of the heating circuit, for single-circuit devices.
2. Secondary heat exchanger for heating DHW, for dual-circuit devices.
3. Multifunctional three-way valve for adjusting coolant flows.
4. Set of gas elements: shut-off valve, torch combustion stabilizer, fine filter.
5. Automatic piezo ignition.
6. Gas burner device in the form of two burners - main and ignition.
7. 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.

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 m 3 / 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.

Technical characteristics of a gas boiler

Let's look at the technical characteristics of the single-circuit boiler Siberia 17:

About the manufacturer

The Siberia trademark is managed by Rostovgazoappart JSC in Rostov-on-Don, probably the largest domestic manufacturer, which also produces a relatively new model range of RGA boilers and the well-known AOGV. The company was registered in 2002, but the plant where the boilers are produced has been in existence for two centuries; back in 1959 it produced the then legendary AOGV-80. All this says that, in theory, the company has extensive experience in the production of budget gas equipment, and the models are constantly in demand.

In practice, boilers under the Siberia brand have really proven themselves to be reliable and problem-free, absolutely adapted to the domestic unstable gas pressure, which is not the cleanest coolant. Often in homes you can even find inexpensive models with a corrosion-resistant steel heat exchanger that operate for more than 10 years.

All models have an efficiency of 90%, which is the highest figure for such a simple design. Gas consumption is also quite low, although not comparable to more expensive Lemax models. For example, the maximum gas consumption of the most popular Siberia 11 (11.6 kW) is 1.18 m3/hour, for the 17.4 kW model it is 1.76 m3/hour.

Installation of floor-standing Siberia. Thick (4 mm) steel heat exchanger, the simplest design from reliable modules.

The manufacturer’s steel heat exchangers, although susceptible to corrosion, are known for their durability and, according to installation practice and owner reviews, often last 10, 12 or more years. The thickness of the heat exchanger steel is 4 mm versus the standard 3 mm in budget boilers from other manufacturers. The automation in floor-standing models is non-volatile, the well-known Italian EuroSit, installed on most domestic boilers. Standard and burner – Polidoro. Such a device means that there is simply nothing to break in the boiler and its service life, with proper operation, is limited only by the life of the heat exchanger.

Of course, there are also known shortcomings that are common to almost all models of the manufacturer. First of all, the owners note the need for constant cleaning: it is advisable to clean the heat exchanger, burner and igniter annually (this takes about an hour), some owners clean the boiler 1-2 times a year using a light cloth and a vacuum cleaner (in general, it is advisable to keep the boiler room clean) . If the boiler modules are clogged, problems with ignition and operation of the automation may occur.

Also, owners often note that the burner igniter is noisy, the clicks (pops) are too loud when ignited, so the boiler must be placed in a separate room.

Otherwise, all models, taking into account their cost, even in comparison with other leading domestic analogues, are devoid of significant shortcomings (otherwise it would be strange, given a hundred years of production experience). Almost all models have been in trouble-free operation for more than 10 years, without causing serious service complaints.

How to choose a room thermostat and save up to 30% per month on heating

For which rooms is it best suited?

The floor-standing gas boiler Siberia 17 is designed for heating rooms up to 170 m2.

This is a common size for a medium-sized private home, large apartment, office or commercial space, etc.

The purpose of the premises is housing or public purposes; such boilers are not suitable for industrial or production workshops due to fire safety or technological restrictions.

Drafts and instability of air flow can have a constant impact on draft, causing the boiler to shut down . This is the main factor limiting the use of units in production conditions.

Nuances of operation

The weight of Siberia wall-mounted gas heaters is 30 kg, steel floor-mounted heaters - from 52 to 90, cast iron - up to 200. The dimensions are standard for all modifications, the height and depth are the same, only the width changes. Water is the recommended type of coolant; its temperature at the outlet of a gas boiler is quite significant: 90±5 °C (that is, it is optimized for heating systems with steel pipes). Only the wall-mounted series has a built-in circulation pump and a coaxial chimney.

As a result, Siberia boilers are suitable not only for heating private houses, but also for industrial facilities.

Reviews

“Two years ago I installed a floor-standing steel boiler Siberia 23 to heat a two-story house with a total area of ​​220 m2. I would like to note the high-quality and uninterrupted work; even in very cold weather, all rooms are well heated. I also appreciated the autonomy of the boiler; the coolant circulates freely when the main pump is temporarily turned off during power failures.”

Ivan Lazarev, Voronezh.

“I use a cast iron boiler Siberia KCHGO 50 to heat a production space of 560 m2. The device is reliable and safe, works without interruption. The average daily gas consumption for such a large area is only 50 m3 in normal weather and not higher than 130 in severe frosts. An additional saving factor is the energy independence of the boiler.”

Sergey Konyshev, Chelyabinsk.

“When choosing a heating device for individual heating at the dacha, I settled on the domestic Siberia model from Rostovgazoapparat. I don’t have a separate room there, so I installed the boiler in the kitchen. During startup, I observed an accumulation of condensation on the heat exchanger, but after warming up the entire system, this went away. I don’t smell gas, the burner hums evenly. He completely met my expectations."

Alexander Kazantsev, Rostov-on-Don.

“After carefully studying reviews of heating gas boilers and reviews of them, we decided to buy a floor-standing model from Siberia for home, the main factor was the affordable price - 19,700 rubles. Delivery and installation were not difficult, we are happy with the result. The productivity of the selected boiler is only 11 kW, but this is enough to effectively heat 95 m2. According to the seller’s advice, we ventilate the chamber every time before starting a new heating period so that there are no problems during operation.”

Igor Sotnikov, Samara.

“I am the owner of a country house with a relatively large area - 190 m2; I purchased a wall-mounted gas boiler Siberia, Top Line model, for heating and hot water supply. I am satisfied with the operation of the device; even in our winter conditions there were no sudden shutdowns. But every time you have to check it before the start of the heating period and be sure to ventilate it, otherwise it won’t start. I also like the performance in terms of heating water - at least 12 liters per minute with good pressure.”

Yaroslav Sintorin, Moscow.

Start-up and operating instructions

The launch is carried out after connecting communications and checking the tightness of all connections.

Needs to be attached:

• Heating circuit forward and return pipelines.
• Gas pipeline.
• Make-up pipeline.
• Chimney.

After connecting the communications, the system is filled with water until it flows out of the signal pipe.

Then open the gas valve, press the pointer handle (all the way) and at the same time press the piezo ignition button of the pilot burner . You must hold it for up to 1 minute until a flame appears on the pilot burner.

After this, the pointer knob is set to position 4, the main burner lights up and the boiler begins to function.

Operation of the units involves periodically cleaning them from dust and soot, changing the current temperature settings as desired, and monitoring the general condition of the system.

If unusual or alarming signs appear, turn off the gas valve and immediately call a technician from the service center to inspect and repair (adjust) the device.

Any independent intervention in the mechanism can cause an accident and failure of the equipment..

How to enable: brief instructions

Identification of boiler control elements.
All floor-standing models are equipped with the well-known EuroSit 630 automation system, so to turn on the boiler you should follow a simple algorithm:

1. Make sure that the gas supply valve is open and there is draft in the combustion chamber (put a match to the window at the bottom of the boiler).
2. Turn the mechanical thermostat (rotator) to the “Off-0” position, and then all the way to the “⭐” position.
3. Press and hold the magnetic valve button (the start button in the center of the thermostat) for 30 seconds, then press the piezo ignition button near the thermostat once without releasing the start button. At this moment the pilot burner should light up; if this does not happen, repeat the steps. If the wick burns steadily, continue to hold the trigger button for 60 seconds before releasing it.
4. Rotate the thermostat to set the desired temperature value.

Please note that the boiler can be restarted after an emergency shutdown (for example, due to wind blowing) 60 seconds after the valve is automatically closed. This is a design feature of the EuroSit 630, intended as a safety measure. Without knowing this, many owners complain that the boiler is very difficult to light after extinguishing.

The most reliable models

All Siberia gas boilers have a good trouble-free operation period of more than 10 years.

The most popular model lines:

1. Single-circuit floor heating with power from 11 to 35 kW: Siberia 11, Siberia 17.
2. Double-circuit gas boilers with simultaneous heat supply for heating and hot water supply: Siberia 17K, Siberia 23K.
3. Models with increased power and cast iron heat exchanger: Siberia KCHGO-40, Siberia KCHGO-16.

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 heat calculations

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 heat calculations

The Siberia brand is one of the best on the heating systems market. Systems with high power are very expensive, but consumer reviews are still positive. They evaluate the quality of use and technical properties of heating devices.

Models

Main modifications of gas boilers Siberia:

• AOGV. Floor-standing design for rooms up to 400 square meters.
• KCHGO. Powerful units with cast iron heat exchangers for heating large areas.
• Top Line. Wall-mounted modifications with copper heat exchangers to serve multiple points on site.

When choosing, it is important to consider the power and size characteristics. The larger the power parameters, the larger the area the boiler is designed to heat. Depending on the availability of free space in the room, the dimensions are selected. Wall-mounted models are more compact. Siberia floor-standing boilers are more powerful.

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.

Consumer Reviews

Most people who own Sibir are happy that they purchased such a unit. The advantages of the product include an affordable price, excellent quality, and much more. However, some equipment owners have found a drawback - the need for regular cleaning, although this is only a routine step in caring for the device.

Consumers especially highlight the Hephaestus model

The reviews highlight several main points.

• Compactness of the product. The large capabilities of boilers with a small size are a definite plus.
• Saving. Here we are talking about a design that uses the heat and energy generated by the combustion of coal or wood. Prolonged combustion occurs. This is very convenient when preparing food, as well as when heating water. This quality was not intended by the developers; consumers noticed it themselves.
• An installation characterized by its simplicity. Installation can be done either with the help of specialists or independently.

• Any chimney. The device is convenient because many different chimney structures can fit it.
• Easy to use. Convenient large doors, as well as holes on the lid, allow you to quickly add fuel. You just need to take into account that its dimensions should not exceed 60 centimeters in length.
• Additional options. The manufacturer took care of customers by installing a thermometer on the unit that shows the water temperature in degrees Celsius.
• heating element. These are blocks that can be connected to the boiler itself. These technologies give the consumer the opportunity to leave the boiler unattended and go about their business. In this case, you don’t have to worry - the boiler will turn off on its own, without human help, and the heating element will also start automatically.
• Possibility of installing a draft regulator. It allows you to control the entire fuel combustion process. This nuance will add practicality and convenience to the use of the unit.

Rules for using the equipment

In order for your boiler to last as long as possible, you should handle the equipment without violating the operating rules:

• Do not turn on a boiler with a broken burner or a clogged chimney;
• the case requires grounding;
• if you use antifreeze as a coolant, then you need to buy a product that has a certificate;
  It is important that there is no ethylene glycol in the antifreeze. You can read about antifreeze for heating systems here
• the water temperature should not exceed 95°C;
• if you install the device near a wall that is covered with a fire-hazardous material, then the gasket should be made of steel or asbestos;
• You can turn on the device only after the system is filled with water/antifreeze;
• Every year it is necessary to clean the chimney and filters.

Cost, service and manufacturer's warranty

The service life of floor-standing gas boilers produced under the Siberia brand, declared by the manufacturer, is 10 years. Official warranty – 3 years.
