Heating apparatus aogv 23 2. Heating systems for summer and country houses. Boilers, geysers, water heaters - Repair, service, operation. Recommendations for assembly and installation. Placement and installation

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 for normal mode, 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.

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 characteristic of all atmospheric models, so they can be attributed to specific feature designs.

Varieties

There are three modifications of boilers Zhukovsky AOGV 23:

• Economy. floor unit with Russian automation, heat exchanger tubular type. 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 remote control, room thermostat, protection against excess 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, which stabilizes 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 not suitable for use. production shops with a large number of openings and technological hatches that violate the air exchange regime and create drafts. 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 gas cock, turn the handle to the “igniter on” position and push it all the way down. 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..

The most affordable energy resource with the lowest level of harmful emissions in modern world is a 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 heating apparatus able to heat housing up to 140-200 m², 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 pipeline system with 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.

Thermosyphon heating system (or system with natural circulation) 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 - automatic sensor 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:

Advantages and disadvantages

A major significant advantage, favorably distinguishing gas boilers AGV 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 operation 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:

1. This is a low efficiency;
2. Equipped with unreliable automation;
3. Significant dimensions of the devices themselves and large diameter pipes;
4. 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") refer to 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 you to carry out the most complete combustion gas without residue.

The use of new coating technology on metal surface boiler body provided an attractive appearance equipment. This makes AGV (gas boilers) good choice for a private house or 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.
