Domestic gas boilers and their manufacturers are presented here

The products are in wide demand among users due to their good technical characteristics and reasonable price. Currently, the average cost of units operating on gas is 14,000-17,000 rubles. Boilers are capable of heating rooms from 70 to 1000 m², it all depends on the specific model.

Kinds

The Ochag company produces different structural types of boilers:

• Floor-standing . They do not require any special installation as they can be placed directly on the floor. This expands installation options compared to wall-mounted models.
• Wall mounted . They require hanging installation on strong, preferably load-bearing walls. Temporary or plasterboard partitions are not suitable for this. The specifics of the installation require reducing the weight and reducing the size of the boiler, which affects power and performance.
• Parapet . They can be used both as part of a heating circuit and as an independent heat source.

By functionality:

• Single-circuit . Designed only to supply the heating circuit with hot coolant.
• Dual-circuit . Capable of simultaneous heating of coolant and preparation of hot water (DHW) for domestic needs.

By type of combustion chamber:

• Atmospheric (open) . Smoke removal occurs through a common house chimney using a stove-type draft, and combustion air is taken directly from the room.
• Turbocharged (closed) . Smoke removal and air supply are carried out by a special turbocharging fan. Possible only on energy-dependent models, but independent ones can also be modified using an external turbo nozzle.

There are many design options for Ochag boilers; the user can choose the most suitable option for his or her purposes.

Series and models

The Ochag company produces several model lines:

• Premium . The series is represented by single- and double-circuit floor-standing models AOGV and AKGV with a power from 8 to 29 kW. There are models with different types of automation - Italian SIT or the company’s own development.
• Standard . A series of floor-standing single- and double-circuit gas boilers. The power of the models is in the range of 7-20 kW. EUROSIT or SABK-AT automation was used.

The most common models are KSG 7, 10 and 15.

Consumer opinions about the technical characteristics of the model

The above-described floor-standing gas boiler “Ochag”, according to buyers, has outstanding technical characteristics. Among them, it is worth highlighting the heating capacity, which reaches 7 kW. The equipment can be installed on an area of ​​up to 80 m2. This is true if the ceiling height is 2.7 m.

In an hour, natural gas will be consumed in a volume of 0.78 m3. As for liquefied gas, the installation will consume 0.64 kg within an hour. This type of fuel can be used when replacing burner nozzles. Before purchasing a gas boiler “Ochag”, you should definitely read reviews about it. From them you can find out that the working pressure of the coolant is 0.1 MPa.

Advantages and disadvantages

The advantages include:

• Durability, reliability, stable operation of boilers.
• A wide selection of models allows you to obtain the optimal design and power of the boiler.
• The energy independence of the units ensures uninterrupted operation of the heating system in all situations.
• High performance boilers.
• Simplicity of design, ease of management and maintenance.
• Low fuel consumption.
• Attractive appearance, compact size.
• Low price.

The disadvantages of Ochag boilers are::

• Difficulty igniting.
• The need to ensure a slope of the system to ensure coolant circulation.
• For more stable operation, the use of external devices is required - a circulation pump and a turbo nozzle.

For non-volatile boilers, these disadvantages are quite typical and are, rather, design features.

Operation and setup

Operation of gas boilers Hearth occurs practically without human intervention, in automatic mode.

The owner is only required to:

• Filling and draining water from the system.
• Switching the boiler to summer/winter mode.
• Periodically clean the housing from dust and dirt.

The operating mode is configured during installation and initial startup. Boilers are sold already configured and adjusted .

At startup, only adjustments are made to the factory settings for the most efficient operation under the given conditions.

The setup must be performed by a specialist from the service center with the appropriate approval and qualifications.

Any independent intervention in the boiler design automatically terminates the warranty agreement . In addition, an inexperienced user with his actions can permanently damage the boiler.

Reviews about the features and technical characteristics of the KSG-10 AT boiler

If you don’t know which model to choose, then it’s worth considering several options for gas heating equipment. Among other proposals, it is necessary to highlight the KSG-10 AT. You can purchase a gas boiler “Ochag” of this model for 11,000 rubles.

It has a floor-mounted design and provides maximum comfort to the consumer. Buyers note a heating output that reaches 10 kW. Heating capacity is 100 m2. Natural gas consumption per hour is 1.11 m3. As for liquefied gas, it can be used when replacing burner nozzles, and its consumption will be 0.88 kg/h. Consumers especially emphasize the rather compact overall dimensions of the installation; they are 250x470x750 mm.

It is impossible not to mention its insignificant weight, it reaches 48 kg. The coolant temperature control range is from 50 to 90 °C. At the boiler outlet, the maximum temperature of the coolant should not exceed 95 °C. Buyers also like the rather impressive volume of water in the boiler; it is equivalent to 18 liters.

How to light a boiler

The procedure for igniting a gas boiler with automatic SABK-AT:

1. Open the gas tap.
2. Place the gas block handle in the “Ignition” position.
3. Press the “Start” button, hold it for about 10 seconds, then press the piezo ignition button 2-3 times until it clicks (ignition is possible through the viewing window using a burning match).
4. Hold the “Start” button for another 20-30 seconds to warm up the thermocouple. The gas valve can then be held open by a magnetic plug.
5. Turn the gas block knob to position 5 and make sure the burner flame is stable.
6. Set the desired temperature on the gas block.

To ignite the burner of boilers with automatic EUROSIT, the same steps are performed, only in step 5 the handle must be turned to position 7.

Why does a gas boiler go out?

The extinction of a gas boiler flame can be caused by external or internal reasons.

External reasons include:

• The occurrence of reverse thrust . The most difficult case, practically impossible to eliminate by conventional means. Sometimes eliminating drafts and opening or closing some doors or windows helps.
• Strong gust of wind outside . Cases of flames being blown out by the wind are frequent; they are the result of an unsuccessfully located chimney or low height above the roof surface.
• Drafts in the room . This situation is completely solvable, the main thing is to determine the source of the draft and close it.

Internal problems may be:

• Stopping the gas supply to the mains.
• Gas valve failure, problems with gas equipment.
• Burner nozzles are clogged with soot and combustion products.

If such problems occur, you should call the gas service and clarify the reasons for the lack of gas. The fuel supply valve must be closed before doing this.

Call a specialist from the service center and entrust him with the repair of gas equipment.

It is prohibited to try to repair the gas block yourself; this can cause very dangerous and even fatal consequences.

Basic faults

The main malfunctions of gas boilers Hearth are problems with the burner - weak flame, extinction after a few seconds of burning, frequent flame failures for unknown reasons.

There can be many reasons for the malfunction of gas equipment; to eliminate possible problems, you need knowledge of the design and operating features of the equipment.

All work must be carried out by service technicians who are certified to work with gas equipment.

The only possible independent procedure may be to clean the burner nozzles from soot.
