Possibility of replacing the AOGV boiler with a wall-mounted boiler. Replacing a heating boiler Replacing a gas boiler in a boiler room

It wears out and as a result, the boiler may need to be replaced over time. There can be many reasons for this, but the most common is the aging of equipment or a decrease in its efficiency, as a result of which the efficiency of home heating decreases and the amount of utility bills increases. Therefore, every person who has autonomous heating installed at home should know how to replace the boiler with their own hands. We will talk about this further.

Types of gas boilers

Before we talk about how a gas boiler is replaced in a private home, let's figure out what types of this equipment there are.

All existing models of gas-fired boilers are divided into two types:

  • closed-type boilers: the burner is located in the combustion chamber, and fresh air is supplied and combustion products are removed through a coaxial pipe;
  • open type boilers: the burner has an open arrangement, due to which air is supplied naturally directly from the room.

In addition, heating equipment is divided into single- and double-circuit. The former are designed exclusively for heating homes, while the latter are also capable of heating water to meet everyday needs.

Permitting documentation

Replacing a boiler in a private house, as well as its maintenance and repair, can only be carried out by employees of the relevant government agencies. This is due to the fact that gas heating equipment can pose a threat to human life.

In addition, for replacement you will need to prepare the following documents:

  • a document confirming the boiler room’s compliance with all safety standards;
  • DVK inspection report;
  • documentation for heating equipment;
  • warranty service agreement;
  • project of the premises with changes made to it.

When you have all the documents in your hands, you can go to Gorgaz to obtain permission to replace heating equipment.

Removing the old boiler

Replacing a gas boiler in a private house begins with dismantling the old equipment. You can do this yourself, since the law allows you to carry out such work without obtaining permits.

Before disconnecting the equipment from the heating system, it is necessary to flush it. This is necessary in order to clean the pipes from contaminants that accumulate in them over many years of operation of the boiler.

Dismantling is carried out in the following sequence:

  • water is drained from the system;
  • the equipment is disconnected from the gas and water supply system;
  • if you have closed equipment, it will also need to be disconnected from the ventilation system.

After this, you can begin connecting the new heating equipment. Dismantling can also be carried out by Gorgaz employees, but in this case replacing the boiler will require a lot of labor and time.

Boiler room requirements

According to safety rules, gas heating equipment must be installed in a separate room with an area of ​​at least four square meters. In addition, the boiler room must be equipped with a good ventilation system. You should choose a place that is smooth and heat-resistant.

The equipment must be installed in a place where there is easy access. If it is a hanging type, then special brackets are used for mounting on the wall.

If you live in an apartment and you do not have the opportunity to allocate a separate room for the boiler, then it is not recommended to install it in the bathroom due to high humidity.

What will be required for replacement?

Replacing gas boilers requires the following equipment, components and tools:

  • new gas boiler;
  • wall hanging bracket;
  • ball valve - 3 pcs.;
  • filters for purifying water from impurities and debris - 3 pcs.;
  • gas valve;
  • gas meter;
  • gas alarm;
  • three-wire valve;
  • Voltage regulator;
  • anchor;
  • metal sheets;
  • requirements for connecting the boiler to gas and water supply;
  • building level.

You can buy everything you need at any specialized store that sells heating systems.

Equipment replacement process

Replacing a gas boiler in a house begins with submitting an application to the relevant authority. If you are installing a similar model of equipment, then no changes to the project are required. If the boiler is more modern or it will be installed in a new location, then drawing up a new project is mandatory.

When Gorgaz issues a permit, you will need to contact the company that will install the new equipment for a construction passport. This document must be submitted to the gas company along with the package of documents discussed earlier in this article.

It is important to understand that the company that will install the new boiler must have a certificate authorizing this type of work. In order for the boiler replacement to be carried out in accordance with all safety rules and regulations, you must have an understanding of installation technology.

Boiler installation instructions

If you have hanging-type equipment, then the first step is to install the bracket. For its fastening, anchors with a strong fit are used. To ensure that the boiler hangs level, it is recommended to use a building level when performing work. If the walls of your home are made of flammable materials, then they are sheathed with metal sheets. If the heating equipment is of a floor type, then no additional measures are required during installation. It is simply installed in the prepared place. It is worth noting that if there is any other gas equipment in the boiler room, then there must be at least 20 centimeters between it and the boiler.

It must be connected to the water supply system through mesh filters, which will prevent debris from entering the heat exchanger. In this case, the pipes should be connected to the equipment through a ball valve. It is also recommended to use a special filter to purify water from impurities. This will extend the life of the equipment.

If the boiler is supposed to be connected to the electrical network, then a three-core cable with a plug is used for this. In this case, the outlet must be grounded. It is recommended to use a voltage stabilizer equipped with an autonomous power supply for connection. This will protect the boiler from failures in the power supply system.

If you have closed heating equipment, then it must be connected to the ventilation system. This is necessary to remove combustion products from the boiler. For connection, they use one that will be responsible not only for the emission of carbon monoxide, but also for supplying fresh air to the combustion chamber.

At the final stage, after connecting the equipment to all communications, the heating system is filled with water and the functionality of the equipment is checked. This is how a boiler of any type is replaced, regardless of the model.

Possible consequences of replacing the boiler yourself

If you decide to replace the equipment yourself, then you may encounter very serious problems. In this case, you not only risk your own safety, but you will also have to pay a large fine. If, after connecting the boiler to the gas pipeline, a leak of blue fuel is discovered, which leads to a fire, then all responsibility for what happened falls entirely on you. Therefore, you should not take risks, but it is better to contact the appropriate authority.

Conclusion

Is it time to renovate the boiler room?

The cost of work to replace the boiler is from 15,000 rubles

Have you been thinking about high-quality home heating? Stop overpaying for utilities. Get advice on how to do this without leaving home. There are many types of repairs. Some are cosmetic, when you need to touch up the boiler or replace a couple of parts. Something that can often be done independently and without the help of a specialist. But, unfortunately, after a long period of operation of the boiler, urgent repairs are required, and in the future it is possible to replace the heating boiler.

Everyone wants to live in a warm place. Especially with the onset of cold weather. When it comes to heating your home, remember that it is an important part of your investment. There is simply no point in overpaying for extra electricity or gas. Most believe that if the boiler is quite old and has served for a long time, then it does not need repairs.

It's better to save some money and buy a new one. To some extent this is true, but we must not forget that new boilers are not adapted to our power outages, power surges and varying gas supplies. This is where most home heating problems arise.

Boiler room repair is the most rational way out of this situation. If the heating system is relatively new, then you can call a specialist who will be able to identify defects or malfunctions. A common cause of breakdowns is automation.

It can most often fail. Poor quality or untimely supply of electricity damages even the highest quality system. You can resort to buying a stabilizer. It will be able to slightly correct the power supply, but it is unlikely that the unit will be able to prevent further damage. It’s better to spend money on boiler room repairs than to buy expensive automation.

Boiler AOGV- a fairly simple boiler apparatus that runs on gas. In previous times, it was quite enough to solve heating problems in residential buildings. In addition to the efficiency of the AOGV, one could talk about high build quality and durability. The equipment rarely failed, which made such a boiler even more welcome not only in residential buildings, but also in utility companies. In general, one would think that this is not a cauldron, but a dream.

But with the arrival of new people on the Russian market, people began to understand that boiler equipment can be even more convenient, reliable, efficient and high-tech. The question immediately arose about the possibility of replacing the AOGV boiler with an imported wall-mounted boiler.

However, many people would like to keep old heating system without modifying it to fit the needs of new equipment. As much as possible? What benefits will a person who decides to make such a replacement receive? What are the features of the installation process for replacing boiler equipment? We will try to answer these questions further.

Features of the installation process for replacing boiler equipment

We’ll tell you right away what to do replacement of the AOGV boiler with an imported wall-mounted version possible and necessary. This will give you a lot of benefits.

Firstly, the new equipment is very compact. In a wall-mounted version, it will take up minimal space in the room.

Secondly, the equipment is aesthetically pleasing. If desired, it can be built into the interior of any style, where the wall-mounted boiler will fit very harmoniously.

Thirdly, the equipment is high-tech. Compared to old AOGV boilers, new automated systems boast the highest operational comfort, functionality, etc.

Fourthly, the equipment is safe, which is explained by the presence of numerous sensors and safety systems. You will be confident that your new high-efficiency boiler will not expose your family to the dangers posed by working with gas energy. With all this, the total cost of such a replacement will not cause total damage to your budget.

Replacing the AOGV boiler with an imported wall-mounted boiler

Now we will tell you about certain features of replacing boiler equipment. Firstly, despite the fact that your heating system will remain the same when replacing the boiler, you will have to achieve its ideal internal frequency so that the new equipment does not have to adapt to old contaminants. Therefore, flushing of the old system should be carried out at the highest possible level.

Secondly, all owners of open systems will have to close the system, which is due to the operational features of the new boiler equipment. At the highest point of the system, where the expansion tank is usually connected, it will be necessary to install an air vent.

If your system has a volume exceeding 100 liters, you will have to install an additional one, since one tank will not cope here. A dirt filter must be installed on the return line. We strongly recommend installing between two taps.

This will allow you to clean the dirt filter from time to time, without having to first drain the water. That's all that is needed when replacing a gas boiler.

Today we will learn how to replace an old gas boiler in a private house, what documents we will need for this.

A gas boiler for water heating of a home in the private sector is calculated on the basis of the declared (nominal) power and efficiency factor (efficiency). Reducing these characteristics, as well as a group of other parameters, requires upgrading the equipment of the room where the heating device is located. The reasons that become the reason for installing new heating equipment to replace outdated boilers are the following circumstances: low efficiency; expansion of the heated area due to extensions to the dwelling or the addition of new devices to the water circuit that heat the terrace, insulated attic or underground floor; the need for additional options; the convenience and coziness of a home in the private sector largely depends on the presence of a water temperature increase circuit. The ability to combine a water heating device and a heating device in one device is provided by 2-circuit blue fuel boilers. Condensation heating devices are replacing atmospheric equipment and devices with forced removal of exhaust gaseous substances (with an isolated combustion compartment).

When calculating the efficiency of modern boilers using previous methods of calculation, the efficiency is more than 110 percent. In addition, the reasons for replacement include wear and tear of the previous heating equipment. The costs of servicing and diagnostics of a boiler that has been used for a long time are quite high. If you replace the boiler on time, the costs will be significantly lower.

Difficulties caused by replacing equipment running on blue fuel are initially eliminated in the legal aspect and only after receiving approval from gas control institutions do they move on to direct technical work. The procedure for this process is as follows:

Application for approval from the gas supervision organization that controls the territory where the replacement will be carried out.
Acquisition of engineering conditions: compliance with the previously approved project, discussion, if necessary, of increasing the limit on gas consumption (renewal of the gas supply contract), conclusion on a key inspection of the gas consumption meter and the compliance of the range of pipes in the gas pipeline.
Drawing up a contract with a specialized company that carries out installation and assumes responsibility for diagnostics and repairs.
Analysis of previous technical equipment for heating.
Installation of a new device.
Acceptance and delivery for use by the gas supervision institution.

Legal support for replacing old heating equipment with new ones

Bureaucratic difficulties caused by the potential extent of harm in case of unauthorized change of the boiler without fulfilling all legal requirements require the collection and submission of the following documents for consideration: for foreign boilers, you will need a certificate proving compliance with Russian safety requirements. In addition, 2-circuit devices are required to have a sanitary and hygienic permit for high temperature H2O for domestic use. Typically, commercial organizations provide this set along with a warranty card.

An inspection document with a positive conclusion on the condition of ventilation ducts and chimneys. A document on the results of connecting the device to technical networks, as well as a document on non-obvious work when installing a coaxial smoke removal path through the wall.
Agreement for warranty diagnostics and service, issued for at least 12 months. with a repair company.
The most important document is the project with the accepted changes. An important point is that the new device must become legal.
The boiler owner himself collects the papers or delegates this procedure to a specialized installation company, which affects the final cost of the services.

Steps to dismantle an old boiler

A common point of view is that a worn-out boiler can be dismantled without much difficulty. In reality, illiteracy in this matter can make it difficult to replace equipment: it can disrupt the integrity of the tightness of the joints of the heating network pipes and lead to premature failure of the new heat energy generator. The generalized list of manipulations carried out assumes the following algorithm: disconnection from the gas pipeline using a tap; devices operating on current are disconnected from the electrical network; the make-up pipe connecting the heating to the water supply is blocked; turn off the guide and supply pipes that ensure the circulation of liquid in the network (having emptied the coolant in advance); dismantle the structure connecting to the chimney.

Installation of a new heating device

In terms of complexity and the scope of tasks performed, installing a new device of the AOGV type differs significantly from installing a wall-mounted one or connecting a condensing boiler. Sometimes replacement means a group of actions: moving pipes with blue fuel, connecting electrical feed wires, and even equipping a drain to remove acid condensate. The use of a new device with the same heating requires installation of screening devices on the return pipeline. It is recommended that such filters include flushing of the network without disconnecting from the structure or a quick-change screening cartridge. The transition of gravity heating to an isolated mode explains the installation of an automatic air plug and an expansion tank of the membrane variety. Specialized companies complete the process of replacing equipment by introducing the facility to gas control structures. Among other things, an important stage is the implementation of startup and adjustment work. The structure is filled with coolant, the operation of the boiler is tested, and the draft in the chimney is tested. The power of the device is adjusted to the heated area. It is advisable to entrust the change of gas equipment to special competent teams. Proper installation is a guarantee of long service life of the new device.
