What is a gas boiler AOGV? The abbreviation means that this is a gas water heating device, that is, a gas boiler for home or apartment heating systems. From conventional boilers that are installed in individual heating systems, gas boilers AOGVs are distinguished by the fact that they have complete energy independence (the ability to fully operate in autonomous mode, without connecting to the electrical network), are equipped automatic system(ACS) monitoring and control, which can, without human intervention, control equipment modes, air draft controllers and flame strength in the wick.
Features and differences of AOGV from other gas heaters
Versatility and autonomy are the main advantages of a boiler in a private home. The versatility lies in the fact that the equipment can operate not only from a centralized gas pipeline, but also from bottled gas - just change the type of burner. Moreover, in the absence of electricity electronic system control is successfully replaced by mechanical automation - this is complete energy independence and autonomy.
For housing of different sizes, you can select boilers of the appropriate power, and this parameter is reflected in the marking of the unit: thus, the brand of boiler AOGV 17 stands for gas-fired water heating unit with a maximum power of 17 kW. 
Heat-generating elements of the unit: automation devices and sensors, combustion chamber, jacket (heat exchanger), air duct (chimney duct). In the Russian Federation, the main suppliers of this autonomous heating equipment are the Borinsky and Zhukovsky plants - all Zhukovsky and Borinsky aogv are produced in a floor-standing version. The Borinsky plant produces floor-standing heaters in a rectangular casing, with automation located in the same casing at the back. All automation is installed in different versions and configurations - this can be domestic mechanical and/or electronic equipment, as well as automation made in Europe or America.
The Borinsky plant produces boilers with a rated power of 7, 11, 17, 23 and 29 kW in two modifications - a single-circuit boiler and a combined unit with two circuits, and this allows heating in an economical mode even small houses with a total area of up to 70 m2. This feature demonstrates the advantage of Borin units over Zhukov units, which are designed for large areas.
The copper thermocouple is the next main element of the circuit, which activates the solenoid valve, which shuts off the gas into the combustion chamber when the wick is extinguished. The combustion chamber, which is equipped with gas boilers for private houses of the AOGV brand, is open, which means that air to support combustion enters the chamber from the surrounding atmosphere. Such an installation scheme must provide for the presence of both natural and forced ventilation in a private house. But if there is good natural draft, an electric fan can be used only in extreme cases. 
The coolant jacket is located in the upper part of the combustion chamber, above the burner. Both circuits (if the AOGV boiler is double-circuit) have their own separate heat exchanger with separated flows of water and/or coolant.
Zhukovsky Machine-Building Plant produces AOGV boiler with rated power of 11, 17, 23 and 29 kW in three versions: economical heater (economy class), universal boiler (universal class), and comfort class.
The automation in these units differs depending on the configuration and country of origin. All boilers have piezoelectric burner ignition, which corresponds to the definition of heater autonomy. Depending on the power of the device, you can find out from the markings in the passport how much area a particular unit can heat. 
Heater parameters
The high efficiency of the AOGV - up to 92% - means that the installation of this equipment will bring maximum efficiency heating, and this is thanks to original design shirts. 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/+90 0 C.
The disadvantage of this equipment can be considered 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 expendable.
The burner in any modification and brand of boiler is made of 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.

Insertion of AOGV into heating
Professional installation of a gas heater in a private home costs approximately 1.5 times less than the average cost of a boiler. Any unit can operate as in, while the energy independence properties are preserved in any case.
Standard installation with sealed circuit - explanation:
- The coolant flows from the heater to the batteries with necessarily installed air vents;
- On return pipes e a circulation pump is installed in front of the boiler entrance, and a coarse filter is installed in front of it;
- The expansion tank cuts into the system before the pump.
In open-type heating systems, the expansion tank itself serves as an air vent, so it is not necessary to install valves on all radiators. The tank is cut into the coolant supply pipe, above the gas boiler, at the highest point of the pipeline; it is also possible to cut it into the return pipe. In systems with natural circulation of the coolant, it is necessary to ensure the required slope of the pipes (2 0 per 10 linear meters) so that the liquid does not stagnate in the system, but circulates freely.
Advantages of AOGV and management
When deciphering the abbreviation, the advantages of the units become clear, namely:
- Simple and easy control of the heating gas unit allows you to organize safe and affordable control of the coolant temperature within the specified parameters;
- All devices, parts and components are manufactured using high-precision technologies, but what is this in practice? This is an absolute guarantee of safety and reliability of operation gas equipment. In addition, some models have manual gas shut-off and coolant temperature adjustment;
- All AOGV brands are non-volatile, that is, they are not tied to electrical networks and are completely autonomous;
- Piping in the heating system can be done with any pipes - polypropylene, cast iron, steel or metal-plastic;
- The heat exchanger (jacket) is usually made of copper, which ensures long service life;
- Pressure drops in the gas pipeline do not affect the stability of operation;
- A high degree of thermal protection ensures maximum heat transfer of the unit and the system as a whole.
Installation of AOGV is advisable only in private residential buildings, and not in apartments due to their high power and large size.
Review of gas boiler AOGV-11.6-3 Economy
The household gas heating boiler with a water circuit AOGV-11.6-3 Economy is designed for water heating of residential and office premises equipped with water heating systems (WHC).
The device runs on natural and liquefied gases. The manufacturing plant supplies devices with nozzles for natural gas. To operate on liquefied gas, it is necessary to replace the injectors for natural gas with injectors for liquefied gas.
These units can be installed in closed heating system with a membrane-type expansion tank. The pressure in the heating system in operating condition (at a water temperature in the heating system of 60 - 80 ° C) should be no more than 1.5 kgf/cm2.
A safety valve must be installed on the riser (outlet pipe), adjusted to operate at a pressure in the heating system of 1.8 ± 0.1 kgf/cm2. To control the pressure in the heating system, a pressure gauge with a measurement limit of 0.4 kg/cm2 must be installed.

The automation unit is an electromechanical device and consists of a block body, inside of which there are valves and a system of levers,
electromagnet, and serves to supply gas to the igniter and burner, regulate the water temperature and automatically turn off the gas supply when:
The igniter goes out.
Gas pressure in the network drops below the permissible level or gas supply stops;
Lack of draft in the chimney.
Draft breaker 1 (Fig. 1) is designed to automatically stabilize the vacuum value in the furnace of the apparatus, i.e. reducing the influence of fluctuations in the vacuum value in the chimney on the draft in the firebox of the apparatus. For successful operation, the draft breaker door 2 must rotate easily on its axis.
Automation gas boiler AOGV-11.6 water temperature control consists of a bellows-thermocylinder assembly 6 installed inside the apparatus tank and a system of levers with a valve located in the automation unit.
An adjusting nut 6 is attached to the block body (Fig. 2), by rotating which you can adjust the automation to a temperature from 50 °C to 90 °C. This temperature change is caused by the movement of the bellows together with rod 5 up (down) when the adjustment nut is rotated.
After heating the water to the temperature corresponding to the setting, the gas supply to the burner is automatically reduced and it switches to the “low fire” mode.
When the water temperature in the apparatus decreases (no more than 15 °C) as a result of heat extraction during heating or hot water, the gas supply to the burner automatically increases. The temperature of hot water in the hot water supply system during its intake should not exceed 60 °C.
The automatic traction system consists of a traction sensor 4 (Fig. 1) mounted on the tank lid and a cable 8 connecting the traction sensor to the magnetic box.

The ignition device (Fig. 3) is intended for attaching the igniter, thermocouple and igniting the main burner. The pilot flame should flow around the end of the thermocouple.
The safety of the gas boiler AOGV-11.6 is ensured by automation, which is triggered when:
The flame on the igniter goes out;
Lack of draft in the chimney;
Gas supply stops or gas pressure drops below the lower value.
In this case, the gas supply to the igniter and the main burner is automatically stopped.
Preparing the AOGV-11.6 boiler for operation
The room where the AOGV-11.6 boiler is installed must have free access to air from outside and a ventilation hood near the ceiling and meet the requirements for the placement of thermal units intended for heating and hot water supply of single-family or
blocked residential buildings.
Installation of a boiler unit in a residential building is allowed only if there is a chimney with combustion products discharged from the device into it. The chimney must meet all requirements.
The chimney channel must have a “live” cross-section not less than the diameter of the connecting gas exhaust device of the apparatus, be strictly vertical, smooth, even, without turns or narrowings.
Outside surface chimney located above the roof must be plastered with cement mortar. The part of the chimney located in the attic must be plastered and thermally insulated.
Below the point where the connecting pipe from the device is connected to the chimney, there must be a “pocket” in the chimney, at least 25 cm deep, with a hatch for cleaning. To ensure optimal operating vacuum in the chimney, we recommend that the chimney height be at least 5 meters.
The AOGV-11.6 boiler must be connected to the chimney using roofing steel pipes. The diameter of the pipes must be no less than the diameter of the device's draft breaker. The pipes must slide tightly into each other without gaps along the flow of combustion products by at least 0.5 of the pipe diameter.
The vertical section of the smoke exhaust pipe, located directly above the draft breaker, must be as long as possible, but not less than 0.5 m.
Laying connecting pipes through living rooms prohibited. It is necessary, if possible, to avoid long horizontal sections of the chimney pipe.
The total length of horizontal sections of connecting pipes should be no more than 3 m. (B existing houses length allowed is no more than 6 m).
The slope of the pipe towards the gas appliance must be at least 0.01. Curvature radii should not be made smaller than the pipe diameter.
The AOGV-11.6 gas boiler is installed near fireproof walls at a distance of at least 15 cm from the wall. If the device is installed near a fire-resistant wall, its surface must be insulated steel sheet on a 5 mm thick asbestos sheet protruding 10 cm beyond the dimensions of the housing.
There must be a 1 m wide passage in front of the unit. When installing the unit on wooden floor, the floor must be insulated with steel sheet over asbestos sheet 5 mm thick. The insulation should protrude 10 cm beyond the dimensions of the housing.
To improve the conditions of water circulation in the heating system, it is preferable to install the boiler as low as possible at the level of heating devices (radiators). The expansion tank is located at the highest point of the system. The heating system must be with overhead wiring.
Surface heating devices determined by calculation. To avoid high hydraulic resistance of the system, it is not recommended to underestimate the diameters of pipelines.
