Gas boilers Siberia: review, reviews, faults

The Siberia gas boiler has left its competitors far behind in many respects. Having recently appeared on the market, the products are popular, occupying the first lines of ratings in positions related to quality and reliability. The equipment, differing in technical characteristics, is used for heating premises of any size - from residential buildings to industrial enterprises. Consumers are attracted to Siberia boilers by their stylish design, innovative solutions and impeccable technical characteristics.

About company

The owner of the Siberia brand is ZAO Rostovgazoapparat. This is a large company producing gas equipment. The year the plant was founded is 1888. Location is Rostov-on-Don. The first in the USSR, in 1959, began to produce gas boilers - AOGV-80. Today the enterprise is an example of automation and robotization of production processes. Products produced by the plant last 20 years or more.

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.

• Heat exchanger material - carbon structural steel.

• Automatic SIT unit consisting of a magnetic valve, a modulating thermostat for on-off switching and a thermoelectric device that controls the flame. There is a re-ignition and fuel pressure stabilizer, piezo ignition and a gas filter.

• Atmospheric burner. Material: heat-resistant steel. Can operate on reduced fuel pressure.

• Powder coated housing.

• Foil heat insulator – to reduce heat transfer and increase efficiency.

• Capillary type thermometer.

Description of combination boilers for home heating

It is not always possible to connect the heating system to the main gas in a timely manner. Of course, you can first use a solid fuel or another type of boiler, and then purchase a gas one, but this will be extremely unprofitable from an economic point of view. A combined heating boiler or equipment with replaceable burners will be an excellent solution to this problem. At first you can use a burner for diesel fuel, and later change it to a gas one. Combination boilers for heating a home are more expensive than gas, diesel or solid fuel. In addition, they are large in size and therefore require an appropriate room. The main disadvantage of combined units is the presence in their design of elements that operate from the electrical network. This is a pump, a fan, etc. Thus, if there is no electricity, the boiler will not be able to work, and in winter this can lead to the entire heating system defrosting. Therefore, you should install a backup electricity generator in advance, which will ensure uninterrupted operation of the heating system. But the advantages of combined equipment are much higher: boilers are durable, reliable, and do not depend on interruptions in the supply of one type of fuel. Combination boilers are usually made of cast iron, this prevents the formation of condensation. Occasionally you can find bimetallic units that are equipped with double walls: steel and cast iron. The surface in contact with flue gases is made of cast iron, and the one in contact with water is made of steel. Among other things, such a boiler is lightweight.

Combination boilers with one burner are designed for gas and liquid fuel. This unit is equipped with two fuel supply lines that approach the burner from both sides. The burner can switch as needed from one line to another.

Combination boilers with two burners do not switch over. One of them is intended for gas, and the other for liquid fuel. If necessary, one burner is removed and another is installed in its place. It is attached with screws to a specially equipped place in the front of the unit or on the door. After this, the liquid fuel or gas line is connected using a union nut.

Whatever boiler you choose, you should first of all focus on its performance, cost and future economic benefits. It is also worth considering the type of fuel that will be preferable to use for heating your home in your area.

Series from Siberia

The manufacturer offers three series:

• Premium Topline-24. Premium models are designed for small buildings. Double-circuit - you can heat water for domestic needs. A special feature of the series is electronic ignition. There is ionization control of fire and exhaust gas. There is an anti-scale function. Efficiency 90%.
• Comfort Siberia. Modifications 23, 29, 35, 40, 50 (heat output, kW). Any option is offered - single-circuit or double-circuit. Designed for large rooms.
• Economy Siberia. Produced since 2005. Four models, differing in the number of circuits and power - 11.6 kW and 17.6 kW. The letter “K” in the marking means two circuits. It is possible to switch to liquefied gas - you can insure yourself in case of an accident in the gas pipeline. The cases are covered with enamel, which protects from mechanical damage.

Parameter table

AOGV Siberia boilers are presented in 5 models. They differ in power, gas consumption, and area of ​​the heated room. For convenience, their characteristics are discussed in a comparative table.

Boilers have different technical parameters and are capable of heating different rooms. They are made of high quality materials and with a reliable security system.

Each boiler has an automatic system that regulates the continuity of burner operation and flame height. This built-in system clearly regulates the temperature using draft and flame sensors, and also ensures optimal fuel consumption.

The patented heat exchanger design ensures minimal heat loss. This increases efficiency and keeps it at an optimal level for a long time. AOGV boilers are single-circuit, that is, they only heat the heating system. But, you can connect a boiler to them. Then the boiler will also provide the house or apartment with warm water.

All boilers have the same height - 85 cm. The depth and width of the models differ slightly, but they are all quite compact and take up little space.

Technical design features

High-strength heat exchanger. In its manufacture, practical materials were used - steel or cast iron, and automatic welding. Service life – 25 years.

• Devices with two circuits heat water in a flow-through copper radiator.
• Thermal insulation layer protects users from burns.
• They are used in any water supply systems - both forced and natural water circulation are suitable.
• Energy independence. Not connected to electrical networks.

Questions and answers

In what sequence should Siberia gas boilers be connected to the pipelines?

After installing the boiler at a permanent place of operation, you must first connect the forward and return pipelines of the heating circuit to it. After this, the double-circuit units are connected to the water supply. The last thing to do is connect to the gas supply pipes.

How can you check the draft of a boiler?

To check the draft, place a lit match under the gas exhaust box. The flame determines whether there is draft or not. Only after checking it and if it is there, open the gas supply valve and set the pointer knob to the “pilot” position.

How are Siberia boilers ignited?

To ignite the boiler, press the thermostat knob all the way. At the same time, you need to press and hold the piezo ignition button until the gas burner lights up. After the boiler is ignited, the pointer knob is set to position “4”.

For what reason can a gas boiler go out?

The main reason for extinguishing the flame of a gas burner is the interruption of the gas supply. You need to check the fuel supply pressure. Other common reasons include: a draft in the room in which the boiler is installed, the occurrence of reverse draft.

What to do if the burner device burns and smokes without dying out?

The reason for this boiler operation may be a lack of air. It is necessary to clean and ventilate the burner and jets.

Gas boilers "Siberia" have proven themselves to be reliable units. They have a long service life and are affordable.

2. The range includes models that do not depend on electricity;
3. Stainless steel burner;
4. Piezoelectric ignition uses fuel until complete combustion;
5. Italian automatics;
6. The case is protected from heat;
7. The circuits are made of copper alloy. This prevents heat loss. 8. In addition, copper does not corrode;
8. The cast iron heat exchanger ensures uninterrupted operation for 25 years, heats up quickly and retains heat for a long time.

Gas boilers are:

• Wall-mounted;
• Floor-standing.

Both of them can be: single-circuit and double-circuit.

Double-circuit heaters are used when there is a need to combine heating with water heating. They have two circuits that simultaneously work for both needs. In addition, the temperature for heating buildings and heating water can be set differently. And in the summer, the boiler can be used as a boiler. Single-circuit boilers, for space heating only.

The lineup

The manufacturer offers several lines:

• AKGV and AOGV. Accordingly, double-circuit and single-circuit. Installed on the floor. Heating capacity 11-35 kW. The material of heat exchangers is most often carbon steel. They heat areas of 125-400 square meters. Water consumption - 4-8 l/min at 35°C.

• KCHGO. Powerful devices 16-50 kW. They heat large buildings, warehouses, and production workshops. The radiator is cast iron.

• Top Line. They hang it on the wall. 24,000 W. Copper heat exchangers. Designed for simultaneous servicing of several water intake points. Designed for houses up to 200 sq. m.

• Aqua. 18,000-23,000 W. This is more of a water heater than a heating boiler. Ignition – piezo/electronic.

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.

Criterias of choice

• Power – the higher it is, the larger the heated area. It is stated in the labeling.

• Dimensions of the room. The calculation of the required heating capacity is carried out taking into account the dependence: for 10 sq. m. – 1000 W. It is not recommended to operate the device at maximum - this increases the wear of its elements. The value needs to be increased by adding 30%.

• Climate.

• Insulation of the building.

• DHW (hot water supply).

• Boiler type. In an apartment it is more convenient to use a wall-mounted version, in a private house - a floor-mounted one.

Price range

The cost of Siberia floor-standing models depends on the power and set of functions of this unit.

The general range is between 20-65 thousand rubles. At the same time, the delivery set includes only the boiler, gasket, instructions and packaging. The chimney and other additional accessories (if needed) will have to be purchased separately .

IMPORTANT!

It is not recommended to save on concluding a warranty agreement. It’s not that expensive, but it will allow you to quickly and freely solve a lot of problems.

Installation

The kit comes with a passport and instructions. The latter is necessary to familiarize yourself with the device, operating principle and rules for using the boiler. After reading the instructions, the user will be able to find out how to turn on the device. It is advisable to entrust the installation to specialists. Installation features:

• Registration of permission for installation - from gas workers.

• Installation is carried out by specialists with a license for the relevant work.

• The kit does not include an expansion tank and a circulation pump - you will have to buy them additionally.

• The device is placed against the wall, so you must leave a gap - at least three centimeters.

• For surface mounting, the device requires a foundation. Usually it is made of brick. Wall-mounted models are firmly fixed.

• There must be no gas leakage during connection. Connections must be carefully insulated.

• If you start the device for the first time, condensation will accumulate on the heat exchanger, which will disappear when the system warms up.

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.

How to use the equipment?

Without violating the operating rules, you can significantly extend the service life of gas appliances:

• Do not turn on the boiler with a broken burner or a clogged chimney.

• The chassis must be grounded.

• When using antifreeze as a coolant instead of water, you need to purchase only a certified product. Containing ethylene glycol is prohibited.

• Water should not heat above 95 degrees.

• When installing the device near a wall that is covered with a fire-hazardous material, it is necessary to make a gasket made of steel or asbestos.

• The device may only be turned on after the system has been filled with water/antifreeze.

• Clean your chimney and filters annually. Make sure all connections are tight.

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.

• 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.

Lemax or Siberia - which is better?

When choosing a domestic inexpensive boiler, the consumer has to compare it not only with European analogues, which are superior in price, but also with products manufactured in Russia. Siberia and Lemax are products of domestic enterprises. Lemax is a trademark of the Taganrog plant. This is a young production that has been supplying its products to all regions of the Russian Federation since 2002. Both brands have an efficiency of 90%. Siberia outperforms Taganrog competitors in the ranking of demand - consumers are attracted to the products of Rostovgazoapparat CJSC by efficiency, heat transfer, appearance and ease of operation. Both plants produce energy-independent models with steel and cast iron heat exchangers. Reviews about Lemax products are neutral - not “premium”, but quite reliable and unpretentious for their cost - a steel device with a power of 10,000 W costs 13,000 rubles, a cast iron device 19,000 W costs 30,000 rubles.
