The correct heating system is essential for maintaining a warm and comfortable home. AGV heating is one option that’s becoming more and more popular. However, what is AGV heating exactly, and how does it operate?
Air-to-ground variable, or AGV, is a contemporary heating technology that effectively controls interior temperature while consuming the least amount of energy. In contrast to conventional heating systems that depend on boilers or furnaces, AGV heating uses heat pumps to draw heat from the ground or the air, depending on the time of year and weather.
The adaptability of AGV heating is one of its main advantages. It is appropriate for year-round use because it can function in both heating and cooling modes. In order to heat the house during the winter, the system takes heat from the ground or outside air and moves it inside. On the other hand, when the weather gets warmer, the process is reversed to take heat from inside the house and release it outside, which effectively cools the interior.
The energy efficiency of AGV heating is an additional benefit. Carbon emissions are decreased and dependency on fossil fuels is lessened by utilizing renewable energy sources like the ground and the atmosphere. AGV systems are an affordable option for both new construction and retrofitting older homes because they are also very flexible and can be integrated with the current heating infrastructure.
AGV heating also gives homeowners more control over the temperature inside their homes. Users can maximize comfort and reduce energy waste by customizing temperature settings for different areas of the house with programmable thermostats and zoning options.
All about heating using AGV
The Soviet Union’s government gave scientists instructions in the 1950s to create a boiler that could function efficiently from a gas pipe without causing major issues, in an effort to address the issue of inadequate central heating in small towns and cities.
Thus, the apparatus gas water heating, or AGV, was created. Following this, AGV heating started to spread across the nation, demonstrating the wisdom of the choice made. The gadget also started to be utilized for hot water supply organization. Fuel savings in addition to a double benefit.
Particular attention was paid to this device by homeowners in private homes under 100 square meters. AGV did a great job handling his responsibilities and worked continuously and efficiently without requiring human presence. Such an apparatus was simple to operate and didn’t cost a lot back then.
Much water has flowed since then, but many country homes still use the outdated AGV, and the owners are not in a rush to replace it with a more contemporary model.
Since there is a market for these kinds of heating boilers, manufacturers decided not to stop producing them rather than risk losing money. They merely made structural improvements, added contemporary controlling and regulating mechanisms, and reintroduced the AGV into the ranks, albeit in a different configuration.
How AGV works
The device has a very straightforward design. He resembles a samovar. Water is poured into the space between the walls of the pipe and the container walls, which is a container with a vertical pipe inside of it. She is going to be the coolant.
The heat in the pipe comes from the gas burned in the boiler firebox. As a result, the water in the tank receives heat from the pipe, and then it starts to move up the heating riser in accordance with the laws of physics.
The automatic device that supplies gas to the burner and regulates this feed is a feature of modern AGVs. It is also an easy process to control.
The device’s capacity has a temperature sensor installed to track the coolant’s temperature. The damper operates automatically when the required value is met, which is demonstrated by setting the heating system’s mode of operation. She puts too much gas on top of the burner. However, there is still a tiny wick that needs to burn. When the coolant’s temperature dropped, the sensor was cut off once more, and the gas supply was ignited using the wick.
This boiler’s automation operates with great efficiency. Gas is a fickle fuel, so you have to use caution when handling it. The automation of the AGV will not turn it on under any circumstances if the wick’s flame spreads, the pipeline’s gas pressure drops, or the chimney becomes clogged.
How to handle AGV
Several considerations regarding the installation and upkeep of this unit must be made in order to prevent the boiler itself from causing needless issues when operating:
- Firstly, the AGV is installed in a separate room.
- Secondly, the diameter of the chimney should not be less than 135 millimeters. The pipe itself needs to be brought to the street above the level of roofing material. The outer part of the chimney and the one that is located on the attic, you need to insulate and insulate. Increasingly, they try to install a kind of pocket for collecting garbage in the chimney itself.
The AGV may only be connected to the gas pipeline by district gas farm representatives, who will also be responsible for registering the device. Make sure the pipeline leading from the radiators to the coolant is insulated. Insulating the reverse circuit is not possible.
Safety is ensured with appropriate setup and use.
The device needs to be installed below where the radiators are located if the house has a diagram with natural coolant circulation. Usually, it is built into a separate room with an in-depth floor or the basement.
The plumbing standards must be strictly followed when choosing the pipe diameter. Furthermore, the angle of inclination of the horizontal pipe wiring sections must be set correctly. It ought to be one centimeter for every meter that the pipeline is long. This necessary step increases the flow of water, lessens the chance of air traffic congestion, and aids in draining the system’s water supply while it is being conserved or repaired.
Please be aware that condensation forms on the walls of the pipes and the boiler when the temperature regime reaches +50 C. It shortens the lifespan of the system’s metal parts and components. Furthermore, the coolant itself stops flowing at this temperature.
"AGV heating, also known as air-to-air heat pump heating, is a modern and energy-efficient solution for warming up homes. Unlike traditional heating systems that rely on burning fossil fuels, AGV heating works by transferring heat from the outside air into your home, making it both eco-friendly and cost-effective. By harnessing the heat present in the air, even in colder climates, AGV systems can efficiently heat your home while reducing carbon emissions. This technology not only provides consistent warmth throughout your living spaces but also offers the added benefit of cooling during hot summer months, making it a versatile choice for year-round comfort. With its simplicity of installation and operation, AGV heating is a smart investment for homeowners looking to reduce their environmental impact and save on heating costs."
Disadvantages of the heating system AGV
Strict adherence to the guidelines for wiring the pipeline is necessary for the heating system with AGV. Furthermore, and perhaps most inconveniently, it does not offer automatic temperature regulation and control for every single room. This situation results in an unequal strategy for fuel consumption. The first flaw is easily covered by insurance. The system will need to have a circulation pump installed in order to accomplish this, and heating will function similarly to Swiss watches.
Many summer homeowners attempt to empty the heating system of water when they are away from home for the winter. You can fill the pipeline with antifreeze to avoid doing this. But use caution when handling this poisonous liquid—the devil is serious.
New generation of AGV devices
Russian manufacturing facilities primarily produce the AOGV-23.2-1 (apparatus of gas-domestic gas) model. It is intended to provide 140–200 square meter homes with heat. A lower power device exists that is intended to heat an area between 100 and 140 m³. These two brands are nearly identical to one another in terms of appearance.
Manufacturers started offering the new combined model AKGV-23.2-1 with a water circuit not too long ago. This unit can be used to manage the hot water supply as well as heat the house. He has also changed in filling. Three steel sections were installed by manufacturers in place of the pipe that ran through the boiler. They have a hollow inside and are formed by stamping. The pieces fit together vertically and form a single chimney that allows the byproducts of gas combustion to exit into a different chimney.
The most astounding thing is that a serpentine that encircles the entire contour inside the boiler is used to heat water for household needs. It is treated with water, which is used in daily life. Additionally, water for heating is heated within the boiler itself. Fantastic two-in-one device, so to speak. In addition, the copper pipe is used to make the coil.
The new model now has an injecting burner, which effectively burns gas without leaving residue. Even if the pipeline’s gas pressure drops, this kind of burner continues to function flawlessly.

A special discussion regarding the new AGV’s automation. This is a special system that has complete control over the heating of the water. What makes up the automation unit is:
- A temperature sensor that controls the temperature of the water;
- Electromagnet responsible for controlling the main gas supply valve;
- Thermocouple that is installed near the carrier. It heats up from the constantly burning torch, thereby creating electric current in the circuit. And the current is the guarantor that the gas supply valve will always be open;
- Traction sensor that is mounted in a chimney and controls the effective traction of the pipe.
Generally speaking, if one of the indicators of the boiler’s efficient operation suddenly appears, the automation unit will never allow it to pull a cruel joke on you. Not a gas leak, not a fire. The most crucial factor is that the automation is set correctly.
How to choose the AGV heating?
An autonomous gas water heater is what AGV decodes as. Stated differently, it is a gas boiler intended for use in hot water supply and heating. They have significantly changed and enhanced the parameters of their efficacy and efficiency over the last few decades. Instead of "climbing" into the past, we will focus on the key considerations when choosing a gas boiler for your house or place of business.
It is best to speak with an experienced specialist to select such a device correctly. To impede the "negligent" seller from trying to sell you something you don’t need or simply don’t work, it won’t harm the customer to have a basic understanding of this subject.
AGV of the Soviet Union’s outdated production model
The key inquiries you need to ask in order to select the appropriate AGV are:
- What area will be heated by this boiler?
- Which boiler option will suit you?
- What materials will be used in the heating system of the house?
- In the heating system of which type this AGV will work?
The first question the qualified seller should ask you will determine how much power the boiler needs.
The seller will be able to select the optimal AGV model based on the precise value of the heated area, allowing you to "be warm" without going over budget.
The following is a list of the typical AGV capacity range:
11.6%, 16.6%, 17.4%, 23.2 %, 29 %, 35 %, and so on.
The boiler’s maximum power is indicated on the technical passport. In actuality, the heat loss from the room must be considered, as well as the need to lower the gas pressure in the pipeline when there is an excessive load during severe frosts.
An AGV with a 11.6 kW capacity will be sufficient for a 100 m 2 well-insulated room with a ceiling height of up to 2.8 m. If the room has high-quality thermal insulation, the calculation is based on the ratio of 1 kW of boiler power to 10 m^2.
Take note! It is best to choose a boiler that is more powerful (at least 25%, in our example, 16 kW) if the room has high ceilings (more than 2.8 m) or heat loss.
Your functional "requirements" for it determine the type of boiler you should get in response to the second question:
- The boiler will hang on the wall (wall) or stand on the floor or a special pedestal (floor option)?
- The boiler will be single -circuit (only for the heating system) or double -circuit (for heating and hot water supply).

The third question has an equally important answer that supports the first since the parameters of the heating system’s materials determine how much power the boiler needs.
For instance, a condensation boiler with a high efficiency (efficiency) "spends" 1 kW of power to heat the heating system’s 12–14 liters of water. In case you are incapable of ascertaining the water volume in the heating system on your own, inform the seller about the heat-emitting components you utilize, such as the radiator, register, or pipe.
Take note! It won’t be any easier for you because the seller’s question could reveal the incapacity of this trade industry representative or, at most, his inattention. Perhaps searching for an alternative outlet point will be more profitable for you.
What risk exists? The boiler can typically be warmed by the system’s larger water volume. As a result, the water’s temperature in the system might not go above a particular point, like 50–60 o C. Furthermore, this might not be sufficiently cleaned to heat the space effectively.
The response to the fourth query suggests that the boiler’s maximum excess pressure be adopted as a parameter. The maximum excess pressure listed in the boiler’s passport shouldn’t be less than the worker if it operates in a "closed" heating system with a substantial amount of excess pressure.
Take note! Because modern AGVs are extremely "crammed" with electronics, they are susceptible to sudden spikes in the voltage of the power supply network. Consequently, when deciding which AGV heating option to choose, it is a good idea to consider purchasing a voltage stabilizer.
It is advisable to install a regulatory thermal cutter on every radiator to enable differentiable temperature regulation in different rooms.
The information in this article is intended to help you have a positive conversation with a "competent" seller rather than make you appear foolish by standing next to him.
Air-to-water heat pump heating, or AGV heating, is a contemporary and effective way to keep your house warm in the winter. AGV heating systems can effectively heat the water in your house and distribute it through radiators or underfloor heating systems by utilizing the inherent warmth found in the outside air.
The energy efficiency of AGV heating is one of its main benefits. AGV heating systems are far more energy-efficient and environmentally friendly than traditional heating systems because they use electricity to transfer heat from the outside air to the water in your home, as opposed to traditional heating systems that only use electricity or fossil fuels.
The adaptability of AGV heating is an additional advantage. These systems are appropriate for homeowners in a wide range of locations because they can be installed in both new and existing homes and they perform well in a variety of climates.
AGV heating systems also give homeowners the option to easily incorporate additional renewable energy sources, like solar panels, to further lower their energy expenses and carbon footprint.
In conclusion, for homeowners wishing to increase the comfort and efficiency of their houses, AGV heating is a wise and environmentally friendly option. AGV heating systems use less energy and have a smaller environmental impact by using the energy of the outside air to reliably provide warmth. Future home insulation and heating will be greatly impacted by AGV heating’s energy efficiency, adaptability, and potential for integration with other renewable technologies.
