How to replace a gas boiler in a private house without breaking the law

Gas boiler equipment in a private house is included in the category of sources of increased danger to humans.

In this context, all activities related to the installation, repair, maintenance and replacement of boilers are carried out only by qualified personnel.

The master must undergo deep theoretical training, get solid skills in handling gas appliances. The qualifications of specialists are documented by a license to perform this type of activity.

Is it possible to replace a gas boiler yourself

According to current requirements, replacing a gas boiler is equivalent to redevelopment, therefore it is necessary to go through a full re-registration process. Nevertheless, the legality of the change depends on which new boiler unit you are replacing the old one with:

• when replacing with a similar a gas boiler of the same manufacturer, of the same model and capacity, there is no need for approval, and dismantling the old one and installing a new boiler can be done independently;
• when replacing with a similar power, but a different model, it is officially required to obtain an agreement and draw up a new project, since it contains the unique serial and serial numbers of the boiler, due to other characteristics, changes in the heating system may be required. However, some owners still change equipment arbitrarily, relying on the fact that checks often pay attention only to power. In rare cases, a fine is paid and a replacement is legalized.

In all other cases: when changing to another model of another power, floor-standing to wall-mounted, including when replacing with a more powerful one, even of a similar model, you need to go through the entire process of coordination and connection.

This is somewhat easier to do, since the heating system is already assembled, and changes in piping or wiring are usually not required. Dismantling the old boiler and installing a new one can be done on your own, but to connect to the gas main and initial start-up, you must call certified specialists, otherwise the equipment warranty will be invalid.

To change a gas boiler to an electric one, you just need to apply for a disconnection from the gas main. Electric boilers with a capacity of over 10 kW require easier approval from the local energy supervision services.

Why is the replacement carried out

During the operation of the boiler, its power and efficiency level gradually decrease. The equipment is outdated and no longer meets modern standards.

The most common reasons for replacing equipment:

• Boiler performance is no longer satisfactory. If you made an extension or connected additional devices (for example, a boiler) to the circuit, then the old unit may not pull the load.
• Inappropriate functionality. Installing a double-circuit device instead of a single-circuit one allows not only heating the room, but also using hot water supply (DHW).
• Rationality issues. Standard boilers consume a lot of gas. But more modern, condensing devices use not only gas, but also steam. This approach increases efficiency by 110%.
• Deterioration or breakdown of equipment.

Therefore, if your old "AOGV" works "at its last gasp", if the cost of maintenance is equal to the purchase of a new device, then replacement is simply necessary.

What designs does the market offer:

• With a closed combustion chamber... This is a safer version because the burner is closed from external influences. The smoke is removed by a fan. The connected coaxial chimney contains two pipes through which air enters and fumes are removed. Requires a network connection.
• With an open camera... An open burner requires air intake from the room to maintain the flame. Good ventilation and connection to a flue gas shaft is required.

How to replace a gas boiler in a private house: step by step instructions

Before registration, you need to make sure that the room, chimney and ventilation comply with the requirements of SNiP 42-01 and MDS 41.2-2000, which we have already described in the installation instructions. Otherwise, permission may be refused, given a list of necessary changes.

The procedure for replacing a gas boiler in a private house is as follows:

1. We go to the local gas distribution organization (Gorgaz, Oblgaz, Rayongaz, etc.), register there and hand over installation application gas boiler. Required documents - passport and any evidence of your ownership of the house and adjacent territory. After submitting the application, the boiler will be queued for shutdown, and after a while it will be issued technical conditions (TU) - this is the permission. Until the technical specifications have been issued, you can start dismantling the boiler (independently or with the assistance of specialists).
2. In the fire authorities or housing and communal services, we find out the contacts of a local organization that checks chimneys (or ventilation ducts, if it is an apartment in an apartment building). After inspection, specialists will issue conclusion on the proper condition of the chimney (or ventilation), otherwise they will give a list of necessary changes.
3. When the TU is already on hand, we order project in the same "Gorgaz" or any design bureau entitled to carry out such work. To draw up a project, you will need data on the model of the gas boiler and meter.
4. With the finished project, TU, conclusion on the state of the chimney (or ventilation), we again go to the local gas distribution organization, where we submit the project for approval, conclude an agreement with the gas workers for boiler maintenance. Now you can install the boiler on your own or with the involvement of specialists (the same local gas workers).
5. The final step is to contact gas workers to accept installation work, connect the boiler to the gas main, perform the first start-up and commissioning. Upon completion of all work, a corresponding mark must be put in the boiler passport (without it, the guarantee for the boiler unit will not apply).

Replacing a boiler unit takes 1.5 to 3 months, it is the same for a private house and an apartment. The procedure may differ slightly depending on the region and city, for example, an act of fire safety or the final approval of all work in the city administration may additionally be required. One of the organizations will notify you if necessary.

Reasons for replacement may be different

If the boiler has reduced its efficiency, noise and soot have appeared, and repair costs are growing exponentially, then the time for replacing the boiler is approaching.

Another reason is reaching the age limit, therefore, replacing a gas boiler in a private house, the rules for arranging boiler rooms directly prohibit the further operation of such equipment, it is necessary.

Before changing it, you need to choose a boiler to replace an outdated and unproductive device.

Procedure for replacing an obsolete boiler

Gas equipment is considered a hazardous device.

Therefore, all work on the installation and maintenance of gas appliances also refers to work with increased danger.

The existing rules unambiguously answer the question - how to replace a gas boiler in a private house - it is forbidden to install or replace boiler equipment on your own.

Only special bodies (gorgaz, raygas, oblgas) have the right to be engaged in the installation of boilers through enterprises that have a license for such work.

To start replacing the boiler, you need to do the following:

1. Write an application to the gas service for obtaining permission to replace the boiler. You need to know that when replacing an old boiler with a similar one, you do not need to create a new project, but if changes have occurred - a boiler of a different type, the location or gas supply scheme changes, then a new project is created.
2. After receiving the answer, you need to hand over the construction passport to the gas service. Collect and hand over certificates of inspection of the DCK, and if an imported boiler is installed - a certificate of conformity.

Removing the old boiler

Having received all the required documents, the company, with a certificate for such work, can begin to replace the old boiler. You can significantly speed up the replacement work by doing an independent dismantling of the old boiler, which is not prohibited by law.

To remove the old boiler, proceed as follows:

• flushing the system before removing the boiler. The dirt accumulated in the heating circuit is removed;
• draining water from the heating system;
• the boiler is disconnected from the gas, then from the heating system and the cold water supply line. If the boiler is of a closed type, then finally it is disconnected from the ventilation system;
• the switched off boiler is removed from the room.

Installing a new boiler

Owners of private houses need to know how to install a heating boiler and who has the right to do this kind of work. The rules prohibit replacing a gas boiler in a private house, the price of violating this rule may be too high.

For installation, a specialized organization can give the owner a list of the necessary materials for purchase, or install their own components, which will be included in the estimate.

After the completion of installation and successful start-up, an acceptance / delivery certificate is signed, the company issues a guarantee and instructs.

Dismantling the old one and installing a new boiler on our own

1. If there are no shut-off valves in front of the boiler, drain the coolant from the system.
2. Disconnect the boiler from the gas main, make-up and heating system.
3. Disconnect the chimney pipe from the boiler, if the model is wall-mounted, you can remove it together with the chimney by disconnecting it from the ventilation or the wall.
4. Dismantle the boiler unit from the mountings (in wall-mounted models the screws of the mounting plate may be inside, to access them you need to remove the front panel).

The installation of a new boiler is carried out in the reverse order and differs somewhat depending on the model; a detailed algorithm with visual diagrams for modern models is always indicated in the operating instructions (passport) of the equipment.

Furnace arrangement rules

Not only at the stage of equipping the boiler room, but also when the time comes to replace the old gas heater with a new one (in this case, the room has already been prepared), it is necessary to make sure that the boiler room complies with legal regulations.

Furnace arrangement scheme.

1. A room for a boiler room in a private house can be made on any floor, except for living quarters, a toilet and a bathroom. In the basements of apartment buildings, the installation of a boiler room is prohibited.
2. The room air temperature should not exceed 35 and be not lower than 5 degrees Celsius.
3. The air humidity level should not cross the 80% border.
4. The boiler room area must be at least 4 sq. M. with a ceiling height of more than 2.5 m.
5. The width of the doorway must be at least 80 cm.
6. The boiler room must have windows, the minimum area of ​​which is calculated according to the ratio of 100: 1 (wall area to the total area of ​​the windows).
7. When installing an open type boiler, ensure that the boiler room is well ventilated. The size of the ventilation opening is calculated according to a ratio of 8: 1 (opening area in cm to the boiler output in kW).
8. Gas pipes are allowed only from metal.
9. The chimney diameter depends on the boiler power and is calculated using the formula: boiler power * 4.3 = chimney diameter in cm.
10. The cross-sectional area of ​​the chimney must be larger than the cross-sectional area of ​​the opening for its connection.
11. The chimney must rise above the highest roof element by at least 0.5 m.
12. The chimney material must be metal.
13. The chimney should not have more than 3 turns and bends.
14. The connecting device and chimney-pipe should be no longer than 25 cm.

If everything is done correctly and the above rules are observed, then the new boiler will work properly for a long time without endangering people's lives. Replacing the boiler isn't cheap, but when it's over, you can enjoy the warmth and comfort of your home again.

Penalties for self-change without approval

Replacing a gas boiler in a private house without permission and without drawing up a project is prohibited by law - Art. 7.19 of the Code of Administrative Offenses of the Russian Federation "Unauthorized connection and use of electrical, thermal energy, oil or gas". The amount of the fine is from 10 to 15 thousand rubles, in the event of an emergency, criminal liability is possible.

They can find a replacement during the next scheduled check: at least, the boiler passport will not have a stamp indicating that the specialists have carried out commissioning work. Then the gas distribution company terminates the contract, disconnects the house from the gas main, and imposes fines.

Nevertheless, in most cases, gas workers do not pay attention to the changes made or turn a blind eye even to serious violations, it is often possible to come to an agreement with the workers. Many owners of private houses, especially in rural areas, actively use loyalty, but what works today may be interrupted tomorrow, and it is impossible to legalize an already installed gas boiler. Therefore, despite the huge bureaucracy, we recommend that you initially draw up a replacement in accordance with all the rules, especially since the process can be entrusted to specialists for relatively little money.

The cost of the work of specialists

Prices for a full replacement, paperwork and commissioning work depend on the type and model of the boiler, the region and the company providing the services. In Moscow and the Moscow region it is about 8-22 thousand rubles, for St. Petersburg - 6-15 thousand rubles, for the regions - 4.5-12 thousand rubles. About half of the cost is spent on dismantling the old and installing a new boiler unit, almost half - on commissioning.

Please note that the procedure for processing the necessary documents is not always included in the replacement service.
