Gas boiler aogv 23 technical specifications. Heating systems for country and country houses. Boilers, geysers, water heaters - Repair, service, operation. Recommendations for assembly and installation. Possible malfunctions and methods for their elimination
The most affordable energy resource with a minimum level of harmful emissions in the modern world is gas. The use of AGV for space heating is the most effective option in terms of efficiency and safety. Independence from power supply and low cost maintenance allow water heaters to take their rightful place among similar devices.
Water-heating boilers AGV, using gas as an energy carrier, began to be produced by ZhMZ (Zhukovsky Machine-Building Plant) since 1967. The new generation of gas heaters is capable of heating homes up to 140–200 m², and the equipment can also be used to provide hot water. To The catches are equipped with a reliable automatic gas supply control system.
ZhMZ products are now represented by about 30 types of boilers. Among them are modifications with power from 11 kW to 68 kW - AOGV, KOV, AKGV. Certified devices that have permission to manufacture and use are capable of heating up to 610 m² of area.
The principle of operation of the AGV
The basis of the design of AGV devices is a cylindrical tank connected by a pipeline system to the entire heating network of the house. Inside the cylinder there is a heat exchanger - a flame tube heated during gas combustion. In the AGV-80 and AGV-120 devices, a turbulator was placed inside, which slightly increased the efficiency of the installation.
The heating system is a network of ascending pipeline, radiators, expansion tank and return pipeline.
This system provides full cycle of the device which includes:
- heating of the coolant - water;
- the rise of the heated coolant through the ascending pipeline to the heating devices - radiators;
- heat transfer;
- return of water to the device for subsequent heating.
The thermosiphon heating system (or natural circulation system) does not require additional installation of pumps, and compensation for water losses occurs from the expansion tank. Waste products of gas combustion enter the chimney and are removed into the atmosphere.
IMPORTANT! The AGV system allows you to install a pump to ensure forced circulation of water. Such a boiler will no longer be considered non-volatile, since electricity is required for the operation of the pump.
The AGV-80 and AGV-120 devices were equipped with an automatic device that prevented the supply of energy carrier when a certain temperature was reached, when the burner wick spontaneously went out, the draft in the chimney decreased, or when the gas pressure in the main was reduced.
When the coolant temperature drops, the automatic sensor is triggered, including the gas supply to the burner.
New generation AGV devices are distinguished by a more efficient design, but all heat and water heating systems operate in the mode of a conventional gas boiler. Structural differences are in the division of the flame tube into separate sections. A coil for hot water preparation is also mounted in the water jacket.
The technical parameters of the first and one of the latest modifications of AGV boilers are presented below:
| Thermal power | Heated area | tank capacity | efficiency | Maximum water heating temperature | ||
| AGV-80 | 7 kW | up to 60 m² | 80 l | 75% | 90˚ | 85 kg |
| AOGV-23.2 | 23.2 kW | up to 200 m² | 35 l | 89% | 95˚ | 55 kg |
Advantages and disadvantages
A major significant advantage, which distinguishes AGV gas boilers from similar equipment, is their independence from the supply of electricity, in other words, there is no need for. Others "pros" the use of devices are recognized:
- affordable price;
- high efficiency indicators: the effect obtained from the use significantly exceeds the costs of ensuring the functioning of the boiler;
- reliability and safety of boiler operation;
- ease of maintenance.
Available Benefits cannot smooth out the characteristic "Cons" that negatively affect the characteristics of the equipment:
- This is a low efficiency;
- Equipped with unreliable automation;
- Significant dimensions of the devices themselves and large diameter pipes;
- The need for strict observance of pipe slopes during their installation.
Knowing the strengths and weaknesses of the equipment, you can reasonably approach the choice.
We choose AGV (gas boiler) for a private house
Features of the house (area, building materials used) and the climatic characteristics of the area - one of the main criteria for a successful choice heating and hot water equipment. The second important feature is the power of the boiler.
Important! Multiplying the power value by 10 m² of area will tell you how much area the boiler can heat. For regions with a harsh climate, it is necessary to provide a power reserve of 25%.
The criterion determining the choice is the price of the equipment, as well as the cost of the materials necessary for operation. Compared to imported analogues, domestic devices are cheaper by ≈ 35%, the cost of maintenance is also three times lower.
Gas boiler AOGV-11.6 and AOGV - 23
The AOGV-11.6 apparatus is a floor modification of equipment from the range of single-circuit boilers of the Zhukovsky Machine Plant (ZHMZ). Designed exclusively for heating needs. Its marking stands for "gas water heating apparatus". The next figure in the brand designation indicates its power - 11.6 kW.
Models AOGV-11.6-3 ("Economy" and "Universal") are double-circuit boilers and can provide the consumer, in addition to heating, also with hot water. With single-circuit devices, these boilers differ in the presence of a steel coil in the design. 
They differ from each other in the features of automatic systems (the first of these is equipped with domestic automation, "Universal" works with the Italian system).
Modern gas boiler AOGV - 23 is distinguished not only by an improved appearance, but also by the modernization of some structural elements:
- durable Italian thermometers were installed instead of unreliable domestic-made glassware;
- automation system of the American company Honeywell allows you to control the smoke exhaust system, maintain heating, turn off the gas in case of breakdowns in the system, in the absence of a burner flame, it blocks the operation of water-heating equipment;
- complete set with an injection burner allows for the most complete combustion of gas without residue.
The use of a new coating technology on the metal surface of the boiler body provided an attractive appearance of the equipment. This makes AGV (gas boilers) a good choice for a private house or summer cottage.
Important! The boiler room can be located anywhere, but not in a residential area. It is imperative to provide for the possibility of air inflow and exhaust in the furnace.
Installation of equipment in accordance with certain technical standards and safety requirements can be carried out by a specialized organization. The exact implementation of all rules, instructions and recommendations for installing the boiler is checked by a representative of the gas inspectorate.
Important! The inspector will give permission to connect the equipment to the main in case of full implementation of all the requirements of the project documentation, security.

DEVICE AND PRINCIPLE OF WORK.
The device consists of the following components and parts: a heat exchanger tank, a main burner, an ignition burner unit with a thermocouple and an ignition electrode installed in it, a combined gas valve (multifunctional regulator), a draft stabilizer, lining parts.
In the upper part of the tank - heat exchanger, a temperature controller sensor is installed, connected by a capillary tube to the thermostatic valve actuator ("bellows - thermoballoon" system), and a thermometer sensor
A design feature of the combined valve 630 EUROSIT is the presence of a device for stabilizing the outlet gas pressure, as well as combining the control of the valve in one handle with the designation of the positions by the corresponding symbols and numbers on its end face and the pointer on the valve cover. The dependence of the temperature of the heated water on the position of the control knob scale is shown below:
The principle of operation of the temperature controller is based on the expansion of the liquid when heated. The working fluid, heated in the sensor (thermoballoon) from the water in the heat exchanger tank heated by the combustion of natural gas, expands and flows through the capillary tube into the bellows, which converts the volumetric expansion into a linear movement of the mechanism that drives the system of two valves (instantaneous and metering ). The design of the mechanism provides protection against thermal overload, which protects the "bellows - thermal bulb" system from damage and depressurization.
- When setting the desired water temperature in the apparatus with the control knob to increase, the instantaneous (click) valve first opens, then the dosing valve.
- When the water temperature in the device reaches the set value, the dosing valve is smoothly closed, switching the main burner to the "small gas" mode.
- When the temperature rises above the set value, an instantaneous (click) valve is activated, completely shutting off the gas to the main burner.
- In the absence of draft in the chimney, the exhaust gases from the furnace heat the draft sensor, the sensor is triggered by opening the normally closed contacts of the thermocouple circuit. The electromagnetic (inlet) valve closes and shuts off gas access to the main and pilot burners. The draft sensor is designed to operate during the absence of thrust for at least 10 seconds.
- When the gas supply from the network is interrupted, the pilot burner instantly goes out, the thermocouple cools down, the electromagnetic valve closes, blocking the gas access to the main and pilot burners. When the gas supply is resumed, the passage through the apparatus is completely blocked.
- When the gas pressure in the network drops below 0.65 kPa, the gas pressure on the pilot burner will also drop, the thermocouple EMF will drop to a value insufficient to hold the valve. The solenoid valve will close and cut off the gas supply to the burners.
POSITIONING AND INSTALLATION
Placement and installation of the apparatus, as well as gas supply to it, is carried out by a specialized construction and installation organization according to a project agreed with the operating enterprise (trust) of the gas facilities.
The room where the device is installed must have free access of air from the outside and a ventilation hood near the ceiling.

** It is allowed to use household coolant "Olga" (manufacturer: CJSC "Plant of Organic Products") according to the instructions for use. After a period of operation, the coolant must be drained and disposed of.
An autonomous home heating system is becoming one of the most common ways to heat a home.
Among the many options, preference is given to gas boilers, as the most efficient and economical installations.
European companies are recognized leaders in the production of gas units, but their products are not always able to work effectively in Russian conditions.
Domestic manufacturers, having analyzed the experience of foreign colleagues, decided to use a completely different approach to the design and functionality of boilers.
Consider one of the models of the Russian gas boiler - Zhukovsky AOGV 23.
What functions does Zhukovsky have gas boiler AOGV 23
The abbreviation AOGV 23 stands for Heating Gas Apparatus with a Domestic Power of 23 kW. This is a single-circuit floor unit that can effectively heat a room up to 200 m2.
Such features are optimal for use in a private house, cottage or other premises. The boiler is designed to perform only one function, which allowed the manufacturer to eliminate all unnecessary parts and unused structural elements.
This increased reliability, reduced the number of failures and breakdowns. In addition, a feature of the AOGV 23 boilers is non-volatility.
In the event of a sudden power outage, the boiler will continue to operate normally, which is important in the conditions of the Russian winter. This feature significantly increases the reliability of the home heating system.
At the same time, the absence of power supply requires a specific location of the radiator system, since the circulation of the coolant will occur in a natural way.
The combustion chamber of the atmospheric type boiler, with air intake directly from the room and natural smoke removal using stove-type draft.
Household antifreeze was used as a coolant, which increases the reliability of the heating system in severe frosts.
Specifications
Consider the technical characteristics of the boiler Zhukovsky AOGV 23:
Advantages and disadvantages of the model
The advantages of boilers Zhukovsky AOGV 23 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 environments.
- Service life is 14 years (or more).
- The cost of boilers is much lower than that of European counterparts.
- The heat exchanger of the units is made of steel, inferior in thermal conductivity to cast iron.
- The appearance of the boilers is inferior to European models.
- The mechanical automation of the boiler is rather weak.
- Dimensions and weight of the unit require installation in a separate room.
NOTE!
Most of the shortcomings are to some extent inherent in all atmospheric models, so they can be attributed to a specific design feature.
Varieties
There are three modifications of boilers Zhukovsky AOGV 23:
- Economy. Floor unit with Russian automation, tubular heat exchanger. There is a temperature sensor.
- Universal. Installed Italian automation SIT, modulated burner, coolant overheating sensor.
- Comfort. In addition to all the options of the Universal models, the boilers have the ability to remotely control a room thermostat, protection against exceeding the temperature of the coolant.
Comfort modification boilers can be distinguished from other varieties externally - they have a rectangular body section, while Economy and Universal are round.
Device
The principle of operation of the AOGV 23 boiler is based on heating the coolant using an atmospheric type burner. Entering the tubular heat exchanger, the liquid receives the maximum temperature, after which it is discharged into the heating system.
The movement of the coolant occurs under the action of the thermal movement of the heated layers upwards, so the placement of all pipelines must be planned with a certain slope. To adjust the temperature to a given value, a three-way valve is installed, which mixes a certain amount of a colder return into the heated coolant.
Natural circulation is unstable and inefficient, so many owners install an external circulation pump to stabilize the system.
What rooms are best suited for?
Boilers AOGV 23 are optimal for use in private homes, public or commercial premises. They require a separate room with the possibility of ventilation, so the installation of units in apartments is not recommended.
Also, production workshops with a large number of openings and technological hatches that violate the air exchange regime and create drafts are not suitable for operation. They often blow out flames, shutting down the heating system and creating a risk of gas leaks.
The best option is a separate room in the basement (basement) floor, which has a window opening with an area of at least 8 m2.
Startup and operation instructions
The boiler is started after installation on a flat horizontal surface and connecting all communications:
- Gas supply.
- Direct and reverse lines of the heating system.
After installation, the system should be filled with coolant. The filling level is monitored using a signal pipe. The boiler is ignited using a piezo ignition unit or a lit match (Economy series).
To start the boiler, first ventilate the room for 15 minutes. After that, open the gas cock, turn the handle to the “igniter on” position and drown it until it stops. Wait in this position for 10-15 seconds, then press the piezo ignition button.
When the flame appears on the igniter, wait another 20-30 seconds, then release the handle. The igniter should continue to burn. After that, you can set the desired temperature of the coolant.
During operation, no specific actions are required from the user, except for periodic cleaning from dust and soot.
Once a year, a foreman should be invited to perform maintenance. For all problems, please contact the warranty or service workshop..
