How to choose the right AGV for heating: technical characteristics and peculiarities of the operation of devices

The abbreviation "AGV" for a long time was perceived as a general name of all heating boilers that worked on gas. In reality, this is the name of the brand name of the production of Zhukovsky Machine Building Plant (now – JSC "ZhMZ"). The gas water heater was a container with a heat exchanger heated by gas. Devices were installed in houses that could not be connected to the centralized heating system. AGV heating became popular in Soviet times due to its cheapness and relative convenience.

AGV heating: what it is and how it works

Modernized AGVs are less common than they were a century ago, but they are still widely used as home autonomous heating systems despite the appearance of new device modifications in recent years. The radiators are connected to the boiler. In addition to providing heat for the house, it can also be used to heat water if needed.

Even though the early AGV models were not particularly attractive, they were excellent at heating small homes.

Principle of operation of AGV heating

The device operates on a very basic principle: gas heats the heat exchanger, which then releases thermal energy into the tank’s water. Via the chimney, combustion products are released outside. Pipes, an upper distribution main, a return, and an expansion tank make up the heating system.

Because of the temperature and height differences, water circulates naturally. The hotter water rises to the top, passes through the radiators to cool, then falls back into the AHU. An expansion tank is needed to make up for the difference in volume between warm and cold water. Overflow is directed out of it via a dedicated overflow pipe. It enables the heating system’s excessive pressure to be avoided.

Automation and safety

The AGV is equipped with simple automatics, which opens the gas supply valve. Automatically triggers when the temperature of water in the tank falls below the set level or the pressure in the pipes decreases, the burner goes out, the chimney is clogged. The model AGV-80 has a simple safety system, thanks to which the water is drained if the membrane ruptures. It is not very convenient, t.к. in such cases it is necessary to completely change the valve. In AGV-120 the problem has been eliminated: the appliance is equipped with a special cylinder with a bellows temperature regulator. The modernized model is more convenient than the previous one, because it allows you to regulate the temperature of water, in AGV-80 there is no such possibility.

Technical characteristics of different models of AGV

AGV-80 was a well-liked model from the earlier era. Model 120 followed, and AOGV-23,2-1 AKGV-23,2-1 is currently in use. The model names themselves contain information about performance and coolant volume. For instance, the AGV-80 has an 80-liter water capacity, while the AGV-11’s name indicates an 11-kilowatt capacity. Modern units have an efficiency of 75%. The functionality of the earlier modifications, whose name indicates the coolant volume, is as follows:

• AGV-50 – 5 kilowatts;
• AGV-80 – 5.2 kilowatts;
• AGV-120 – 10 kilowatts.

Current models come with Honeywell automatics and imported sensors. With the addition of a piezo element, the ignition is now improved. The body coating has grown more damage-resistant, and the new models have an attractive appearance. A water circuit modification has been made, enabling the provision of affordable hot water and heating. As a result, domestic consumers give the model AKGV-23,2-1 a positive evaluation.

The AGV-80 is among the original models.

Advantages of gas appliances

Economy of scale. The purchaser can purchase the Russian-made apparatus for a substantial discount compared to its international counterparts. One of the most significant benefits is this. Additionally, heating is reasonably priced. To further cut expenses, our fellow countrymen install additional automation that cuts the pumps off when the water heats up.

Design simplicity. A system is less likely to break down and need repair the simpler it is. The AGV has a straightforward design and requires no special maintenance or care. Additionally, repair is not too difficult, reasonably priced, and readily available replacement parts.

Independence from the source of power. Since the appliance doesn’t require electricity to function, its disconnection has no effect on it.

Let"s pay attention to the disadvantages

Large. The enormous boiler occupies a lot of room, and cleaning the area around it is challenging due to its legs. But the issue has been resolved: wall-mounted boilers, which are contemporary AGV heating models, are available. Consequently, this drawback only affects floor units.

Inconvenience to operations. Due to the fact that everything is known in comparison, this disadvantage is relative. Russian analogs are more difficult to use than imported ones.

Long warm-up time. The room cools down for an extended period of time, which is a plus, but it also stays heated for a considerable amount of time, which is a drawback.

Plan for AGV heating and hot water provision

AGV-heating in an apartment

Many apartment building occupants have started to reject centralized heat supply due to the ongoing rise in utility tariffs and opaque pricing structures. Select AGV-heating as an alternative. A special permit from the appropriate services is needed in order to install a gas appliance. Formalization is generally simpler in cases where the apartment is housed in an older, low-rise building with sizable stove chimneys. A removable chimney that is led outside through a hole in the wall can be installed. Getting the necessary permission for autonomous heating equipment in an apartment is not simple, but it is possible.

The appearance of a contemporary AGV heating system in an apartment

Capacity is the primary factor to consider when choosing an appliance. The climate and the room’s level of thermal insulation must always be considered when making calculations. The best specific power for an AGV installation is between 0.7 and 0.9 kilowatts in the south and 1.5 to 2 kilowatts in the north. It is also advisable to consider the material’s resistance coefficient and the pipe’s length. Since this is typically challenging, it is best to speak with experts who can accurately determine the required parameters.

Gas boilers AGV-120

The AGV-120 gas boilers are intended for water heating applications in buildings. Their 120-liter tanks hold heated water that is maintained within the boiler without the need for forced circulation. Modernized units that are more recent have a coil at the top of the tank.

This kind of boiler can be used to heat buildings and provide hot water for household needs at the same time. It has a water-filled cylindrical galvanized steel tank.

There is a flame tube inside the tank that is intended to enhance the heat transfer to water, expand the heating area, and remove combustion products from the furnace.

The device’s casing is composed of sheet steel. Slag fills the gap between the tank and the casing, providing dependable thermal insulation. Burner made of cast iron with fire holes oriented vertically.

The heating system receives hot water extraction from the top and cold water inlet from the bottom. The return line pipe is connected to the water inlet fitting if the boiler is used for space heating.

A thermoregulator controls the temperature of the water by inserting its thermocouple inside the tank. A thermocouple and solenoid valve regulate the burner’s operation.

Figure 1. AGV-120 gas boiler

1, 3, connections for the hot and cold water inlets and outlets; 2, reflector; 4, draught breaker; 5, tank; 6 casing; 7- thermocontroller; 8 is for thermocouple; 9 is for igniter; 10 is for main burner.

There is a heat exchange pipe with an extension tube in the middle of the tank. Slag or glass wool insulation is placed between the tank and the casing. The flame tube’s outlet is situated above a thrust breaker.

The low-pressure injection burner, where the igniter is mounted on the bracket, is located in the appliance’s lower section. Two flame tongues are present on the igniter; one heats the thermocouple junction, and the other ignites the primary burner.

The burner mixer is a profiled tube with a 90° bend. There is a cast iron nozzle attached to the mixer diffuser.

The nozzle’s flame holes are drilled in unique troughs arranged in a single row, which enhances the flares’ secondary air supply. This requirement is necessary since the burner runs on an excess air ratio.

The way the holes are arranged around the circumference helps the bonnet distribute heat evenly, and having a lot of holes allows for the highest flame height.

The gas boiler AGV-120 is outfitted with automated safety and regulation mechanisms. An electromagnetic valve and a thermocouple connected to it via wires make up safety automatics.

When the appliance is operating normally, the igniter heats the thermocouple junction, an electromagnetic field (EMF) forms in the circuit, and a solenoid valve winding conducts electricity to maintain the valve open. The primary burner receives the gas flow.

The solenoid valve shuts off the gas supply to the main burner and the igniter in the event that the igniter goes out and the thermocouple junction cools down. It is necessary to manually relight the igniter, but not before two minutes have passed.

Only after the device is filled with water is it turned on. Simply turn on any hot water tap and make sure that water is flowing out of it under pressure to accomplish this.

After that, open the gas duct tap in front of the appliance, approach the igniter with a lit match, and turn on the tap. The electromagnet’s button must be lowered within one to two minutes of the igniter being turned on; the button must stay in the lower position.

Open the main burner tap and light it after confirming that the igniter is lit. It can only be rekindled after the furnace has been ventilated for two to three minutes if the burner fails to ignite and the igniter goes out.

After turning on the boiler AGV-120, you must shut the door and use a lit match to see if there is any vacuum in the chimney. If there is no vacuum in the chimney, using the boiler is strictly prohibited.

The thermo regulator cuts off the gas supply to the main burner once the water reaches the desired temperature. The thermo regulator restarts the gas supply to the main burner when the water temperature in the heater falls by five to ten degrees (due to hot water extraction or heat losses during heating).

The unit’s right lower nut can be automatically turned to adjust the maximum water temperature. The nut should be turned upwards when the temperature rises and downwards when it falls.

Close the taps on the gas pipe in front of the appliance, the igniter tap, and the main burner tap to turn it off.

The people who operate the appliances are those who are familiar with the operating instructions and fundamental safety guidelines for gas appliances.

Installing AGV-120 boilers in bathrooms and kitchens that release combustion products into the chimney is an option.

When utilizing these units, the bathroom’s volume must be at least 6 meters. It is not necessary to expand the kitchen’s volume beyond what is planned.

Fig. 2. The AGV-120 boiler installation

Figure 2 depicts the installation of the AVG-120 gas boiler. The pipes that connect them to the chimney are made of roofing steel and should have a minimum diameter of 100mm. The pipes range in thickness from 0.8 to 1 mm. The connecting pipes’ horizontal sections cannot be longer than 6 meters in total.

AGV boiler defects and methods for fixing them

The igniter flame goes out when the anchor is not held by the core.

– Solder oxidation at the magnetic valve’s thermocouple contact points – Use a wrench to unscrew the cap nut attached to the magnetic valve. Then, clean the contact washers by wiping off oxide films with an emery cloth before replacing the cap nut.

– Contamination of the armature and core poles – Unscrew four screws, take off the trigger cap and armature, and use a soft cloth or chamois to clean the electromagnet’s armature and core planes without scratching the polished surface. Put the unit together and place it where it belongs.

– The thermocouple has burned out and is not producing electromagnetic fields. – The thermocouple needs to be replaced. Attaching the start button to the magnetic valve is not permitted at all.

2. The igniter flame doesn’t burn or smokes

– Use a 0,3 mm thick plate to clean the igniter slot because the igniter hole is clogged.

3. A rupture in the diaphragm of the safety valve

– The temperature in the tank is higher than 100 to 1500C or the hydraulic pressure is greater than 6 atmospheres. – Remove the safety valve body from its screw, insert a spare membrane in its place, and tighten the body again. It is imperative that the safety diaphragm is inserted neatly between the two gaskets in the housing and is free of any external defects or kinks.

4. Boiler water does not reach the necessary temperature when the AGV-120 is operating.

– Using a screwdriver, remove the locking screw holding the pointer handle to the stem and pull it to the lowest (or highest) position. Then, replace the screw to secure the pointer handle and pull it to the highest (or lowest) position once more to adjust the temperature of the water in the tank. It needs to be done multiple times if the required temperature is not reached in one turn.

5. The igniter and burner flames out

– There is not enough chimney draught. There is no combustion product exhaust from a chimney. – Make repairs to the chimney in compliance with chimney regulations.

The anchor of the magnetic valve is not drawn to the core. More air entering the burner through the mixer than the mixture requires – Adjust the air vent to lower the air supply.

6. Soot on the thermocouple’s tip

– Inadequate primary air flow and incomplete combustion of the gas mixture -The need to use a sharp object to remove soot and clean the 6 mm-diameter igniter post hole.

7. Sounds or flames seeming to separate from the gas burner

– Reduce the air intake by turning on the mixer’s blower. – Increase the burner’s air intake through the mixer.

8. Smoking burner flame (a burner flame is deemed normal if the gas burns blue throughout the burner and measures between 80 and 115 mm in height).

Reduce the primary air supply to the mixer by using the holes in the air vent. – Turn the mixer’s air vent to increase the air supply.

9. The thermostat allows some gas to pass through when the burner’s gas supply is cut off.

– The thermoregulator valve’s seat and valve are dirty. – Remove the valve cup and clean the seat and valve. If required, lap the valve. Adjust or reinforce the operation of the check valve and spring. Before putting the cup back, lubricate the valve and seat with machine oil.

AGV heating

AGV heating was once thought to be the most common—and occasionally the only—method for heating private residences in the USSR. At that time, a sizable portion of the nation was covered by gasification, which allowed the populace to switch from stove heating to natural gas. In the beginning, the only available option for providing heat for private homes was gas boilers AGV. Even though there is now a much wider selection of equipment, these devices are still available on the market and have maintained their appeal. We will examine the built-in features of these devices in this article.

AGV construction

The AGV 80 gas boiler, which was the most popular model at the time, operated on a principle that, in its simplicity, was similar to that of a regular kettle filled with water placed on a gas stove. One vertical steel pipe had a crude round burner installed beneath its mouth, with a chimney pipe at the top.

The diagram illustrates that the 80 model and the more potent AGV 120 did not have any copper or steel heat exchangers. Instead, the single flame tube was submerged in a cylindrical water tank.

A turbulizer was inserted inside the tube to slow down the speed of the departing gases, slightly raising the unit’s efficiency. The appliance was fitted with an automatic system that shuts off the gas supply to the main burner when the pressure drops or the water reaches a specific temperature, as seen by the scheme. The diagram illustrates that the more potent AGV 120 boilers were typically of the same design:

In addition to the unit’s larger size, the burner output and temperature sensor in this instance are thermoballoons rather than standard brass tubes with welded rods. The capillary tube’s expansion of kerosene affected the gas valve’s mechanism, causing it to close when needed. The following table displays the general technical specs of the boiler AGV 80 and 120:

Of course, the automatic gas water heater (AGV) boilers of today are more dependable and efficient in their construction. The apparatus’s water jacket has a coil installed in it to prepare water for DHW needs. The flame tube has been divided into multiple sections, each containing turbulizers. The diagram makes the details easy to see:

Modern features include the boiler’s thermostat, gas valve, and entire automatic system. Russian-made devices are included in the budget modifications, while more expensive Italian ones are. They are made to turn off the main burner’s gas supply in the event that:

• the draught in the chimney will be lost, for which the corresponding sensor is responsible;
• The flame breaks off or the burner dies out spontaneously;
• gas pressure drops in the gas mains.

Notably, when the heat transfer medium’s temperature hits the predetermined level, the gas supply is also shut off. To put it briefly, every system in the updated AGV units for private homes operates in the same manner as a traditional gas boiler. The arrangement of heat exchange is the only difference.

Positive and negative sides

Because gas consumption was not a major concern in the past, the device satisfied both manufacturers and buyers due to its low cost of production. Water heaters are now manufactured in compliance with current safety and energy-saving regulations, and their efficiency ranges from 86 to 89%. The following table displays the technical specs of the boilers manufactured by AOGV, the company that builds Zhukovsky Machine-Building Plant:

Note: Models with an imported "Universal" and "Comfort" series are the ones with the Russian automation unit, and they are part of the "Economy" line. In the acronym, the letter "O" stands for "heating," and the letter "K" for heating water for district heating and waterworks.

Now, let’s use AGVs to impartially evaluate the benefits of heating. Thus, the following benefits are present in the currently available autonomous gas water heaters:

Low equipment cost: this is these devices’ primary benefit; out of all gas heaters, their cost is the most reasonable;

• simple design: any gas boiler AOGV or AKGV is easy to operate and maintain;
• reliability;
• compactness;
• energy independence: the appliance does not require electricity for its operation.

There are drawbacks as usual. The unit’s longevity is called into question due to its subpar construction. The Russian automatics on budget units are malfunctioning, and this is a universal issue. The condensate formation problem was carried over from their "ancestors" to gas boilers AOGV. Even the instruction manual states as much: condensate dripping from the tank walls will drip on the burner until the coolant is warmed up to a temperature of 25 to 30 °C.

Problems arise with AKGV combined boilers when heating water for DHW during the summer. The device enters normal mode after ten minutes, per the same manual. following the hot water tap’s opening, which is not very practical for users.

Tips on installation of combined cycle boilers

It should be evident right away that AGV heating is the most straightforward natural gas heating method for a house; its organization is neither unique nor difficult. Assume you have invested in a non-independent domestic gas heat generator. As a result, all installation-related requirements for this kind of equipment must be met, specifically:

• it is necessary to provide a good draught for removal of combustion products. It is necessary to mount according to all the rules of the chimney for AOGV height of at least 5 m, connect the heater to the exhaust ventilation ducts is not allowed;
• The diameter of the chimney should not be smaller than the outlet pipe of the appliance, and the total length of horizontal sections – not more than 3 m. At the bottom of the vertical part there is a hatch for cleaning and a condensate removal system;
• Since the heater takes the combustion air from the room, it is necessary to organize a good supply and exhaust ventilation;
• the aisle in front of the unit should be kept 1 m, the distance to the nearest wall – at least 200 mm. If it is made of combustible material, it is necessary to install a screen made of asbestos sheet or basalt cardboard.

Given that installing an AGV in a private residence necessitates connecting it to the gas supply network, it should be noted that only licensed businesses with authorization from the service provider organization are authorized to carry out these tasks. Maintaining slopes of 3-5 mm per 1 m of pipe is crucial when installing an electricity-free gravity heating system.
