The most important factor when choosing a gas pipeline system in private property is the presence of a gas main in the settlement or in its immediate vicinity. Without it, gasification will have to be based on autonomous design solutions.

Professional services in the field of gasification of private households

The process of connecting a private house to the gas main involves many legal and technical nuances. Among them:

• legal registration of the land plot;
• registration of rights to a building;
• preparation of a whole package of documents to obtain the appropriate permits for the installation of equipment;
• preparation of the project and installation of gas in a private house;
• permission to connect to the main pipe, many other technical and legal issues.

The Obedinenie-Gaz company provides homeowners in Moscow and the Moscow region with all services related to gasification of facilities. As a long-time and permanent partner of FSUE MOSOBLGAZ, one of the largest gas distribution companies in Russia, we quickly and successfully solve problems of any degree of complexity.

When all preconditions are met and the necessary documents are ready, it is time to develop the project and design documentation. Then installation work is carried out in accordance with the decisions made on the construction of the internal network and the permits obtained for the installation of gas equipment in the house and connection to the gas main.

• Within the framework of each project and at the request of the customer, we provide a full range of services related to the installation of a gas pipeline in a private house, providing prices and price lists for them in accordance with the individual terms of the contract and a pre-calculated estimate.

Local gas pipeline and connections of a private house to the main line

Local gas pipelines are built in the absence of main gas pipelines in the immediate vicinity and always taking into account the characteristics of the facility, the requirements of the owner and safety levels. Gas boilers are installed and an agreement is signed for the supply of natural gas in containers of the required volume.

Of course, centralized gas supply is more convenient and simpler. This is also more reliable, since suppliers who provide fuel to private boiler houses do not always approach their task responsibly. You will have to look for a reliable organization.
Installation of a gas pipe to a private house if there is a main line is carried out in two ways:

• aboveground;
• underground.

In the first case, the pipe through which gas is supplied to the building is placed on special brackets or supports, leaving it in the open air. This method is not very expensive, but requires constant monitoring and maintenance of the highway in order to protect it from the effects of weather conditions and precipitation.

The underground method is 20-25% more expensive than the previous one. Since the gas pipeline is laid in trenches dug in the ground, it is safer, no maintenance is required, and the area looks much more attractive.

Requirements for the materials used and installation of the gas network in a private building

Installation of gas in a private home and reliable operation of the gas network is impossible without compliance with a number of conditions and standards. We guarantee this 100%.

• All materials used in the construction process, regardless of their further purpose (pipes, valves, electrodes), are of high quality, confirmed by relevant documents.
• Our craftsmen place dismountable joints in open areas to ensure easy access. This makes it possible to assess the condition of the connection at any time and carry out repairs if necessary.
• It is strictly forbidden to embed pipes and other components of the gas network into walls, foundations of buildings. In certain cases, permission is given to lay a pipe in a channel specially made in the wall, but only after approval of the project.
• It is also prohibited to attach the gas pipeline to window and door frames, transoms and trim, or plywood partitions.
• It is strictly unacceptable to have distortions when laying local pipelines for supplying gas to premises and territory.
• For horizontal areas, an inclination towards the equipment is allowed within 0.002-0.005 meters, and in vertical areas any inclination is excluded.
• A slope of 2mm/1 meter is allowed only on a riser located on a staircase or in a kitchen space.
• Our craftsmen install the taps by positioning the axis of the plug parallel to the wall, on which the thrust nut cannot be located.

A very important safety factor is maintaining the required distances.

• The minimum distance from the pipe to the floor can be 2.2 meters, to the ceiling - from 10 cm.
• The distance between the wall and the pipe is usually specified in the design documentation.
• Its minimum value is equal to the radius of the pipe, and the maximum is 10 cm.

For the construction of a local gas pipeline, we use pipes made of low-carbon or low-alloy steel with a diameter of 150 mm and a wall thickness of 5 mm. We use both welded and seamless products, which are connected to each other only by gas welding using high-quality electrodes.

We recommend installing not only the main gas meter, but also a control gas meter when connecting to the main line, and at least one meter for autonomous gasification. During operation, you can not only monitor actual gas consumption, but also look for options for saving fuel.

Peculiarities of pricing when installing gas equipment in a private home

Like any other company working in the field of gasification of private facilities, Obedinenie-gaz has a certain price list, with the help of which the cost of the entire range of work carried out is calculated in advance. As a rule, the financial component of these works is unchanged throughout Moscow and the region, but a number of parameters influence the overall estimate.

• Discuss upfront costs with our consultants by phone or online.
• Call a specialist to the site to more accurately and accurately correlate your requirements with the upcoming costs.
• Also take into account the technician’s recommendations regarding the safety of equipment operation and permissible loads for the selected configuration.

To obtain favorable terms of cooperation with the Obedinenie-Gaz company, we suggest considering the option of comprehensive services. In this case, we will provide discounts on the total cost of all services included in the turnkey package. We also provide individual types of services if our clients do not require the whole range of services in one place.

Please note that the total price of installing gas equipment in a private home largely depends not only on our starting tariffs and the complexity of the project, but also on the materials and equipment used by the company’s specialists. We discuss them and always try to find the most cost-effective solutions without compromising the quality of the result obtained, taking into account operational safety, reliability of all components of the gasification system of the building, and compliance with the loads.

Bringing gas to a private house or cottage is a technically complex task.

The gasification process, starting with the collection of necessary documentation and ending with the installation of equipment, is labor-intensive, very expensive and lengthy.

But the cost of equipment and services for installing a gas pipeline will pay for itself over time, since gas, as we know, is the most economical energy carrier.

There is a procedure for solving the problem of gasification and standards for gasification of a private house, compliance with which is mandatory for homeowners and organizations performing work.

The very first step in solving the problem of gasification of a private home will be obtaining the appropriate technical conditions. They are provided by the gas service department at the place of registration of the house. The period for providing technical specifications from the date of application, in accordance with current legislation, is no more than 10 days. This service is provided free of charge.

The next stage of the task of supplying gas to a private house is preparing a package of design and estimate documentation. Such work is carried out by design organizations, and sometimes by the gas supply organization itself.

After receiving the technical specifications, it is necessary to conclude an agreement with them to develop a project for supplying gas to a residential building.

The developed project is further coordinated with the technical department of the organization responsible for providing gas in a particular region. Upon completion of the approval procedure, all that remains is to select an installation organization that will directly supply gas to the house.

In each specific case, when developing a gasification project for private houses, many circumstances are taken into account. Let's briefly look at the main ones.

Selection of gas pipeline

Gas pipelines, based on their location relative to the surface of the earth, are divided into types such as above-ground and underground.

They differ in the method of direct introduction into the room for subsequent distribution of gas throughout the house (floors).

The price also depends on the type of gas pipeline. Thus, an underground gas pipeline is approximately 60% more expensive than an above-ground gas pipeline. But despite this, home owners single it out as preferable.

An underground gas pipeline has greater protection from environmental influences. It is more difficult to damage mechanically. In addition, it has a long service life.

Overhead gas pipelines also have positive features. As already noted, the cost of an overhead gas pipeline is noticeably lower than an underground one. Aboveground pipelines are recommended in cases where the composition of the soil causes corrosion of the pipe metal, which will significantly affect the performance of the gas pipeline when underground. If the distance from the main line to the house is large, it is much easier to conduct gas above the ground.

Requirements for pipe selection

Polymer pipes are highly resistant to various chemical compounds. They are elastic, durable and reliable, almost seven times lighter than steel, do not conduct electricity, and therefore do not require additional protection from electrochemical damage before laying in the ground. Their installation is simple and convenient, and the warranty period is about 50 years. Such pipes are very often used in regions with low temperatures.

However, pipes entering directly into the building, in accordance with current gas pipeline standards, are made only of steel. The same standards apply to gas pipes inside the house. Polyethylene pipes must not be used in places where winter temperatures are below -50 degrees, in areas with high seismic activity. You cannot use polyethylene pipes for above-ground gas pipelines, etc.

On the norms and rules for gas pipeline installation

There are a number of rules that builders must follow when carrying out installation work when supplying gas to the house:

• the optimal depth for laying a gas pipeline in the local area should be from 1.25 to 1.75 meters from the ground surface;
• directly at the entrance to the building - from 0.75 to 1.25 meters;
• You can enter the gas pipeline into the house through the wall or through the foundation;
• the height of the room where the gas stove is planned to be installed must be at least 2.2 meters;
• the premises must be equipped with a ventilation system with access to the street;
• Kitchen ventilation cannot be installed adjacent to living spaces.

Requirements for autonomous gasification of a private house

If it is impossible to supply gas to a private house from the central pipeline, it is possible to gasify a private house by using imported gas - propane-butane cylinders, the volume of which can be 50 and 80 liters.

The volume of gas in such cylinders is enough to satisfy the household needs of a family of 4 people for 1 month.

Such cylinders should be stored in a designated place (preferably outside residential premises) in a metal cabinet. This will protect your home from accidental gas leaks or unexpected fires.

A special pressure regulator must be attached to the cylinder, which should bring the indicator to normal, and only after that the gas will flow directly to the devices.

Gas pipe entry points must be provided at the design stage of the house.

The cabinet for cylinders must be installed on a foundation with a height of at least 0.2 m, and also firmly attached to the wall of the house.

When laying a gas pipeline from the cabinet, the following requirements must be met:

• the height of the pipeline must be at least 2.5 m from the ground;
• the pipeline must be securely attached to the walls of the building.
• the pipeline should not cross window and door openings;

Cylinder equipment will not cope with the task of heating a house, but if the only consumer of gas is a kitchen stove, then this will be the best option for a private house or cottage.

Installing an autonomous gasification system will help solve the issue of heating your home. And here specialists will come to the rescue, for example, company "Nordstroy"(St. Petersburg), which has serious experience and performs work on gasification of private and commercial, production facilities, maintenance of boiler houses and utility networks.

About regulatory documentation

Construction standards for gasification of a private house are set out in regulatory documents that are valid today - these are SP 42-101-2003 and SNiP 2.07.01-89.

Gas distribution networks can be divided into external and internal.

Gasification, that is, the construction of gas distribution stations and external networks in villages, towns and other populated areas, is carried out by specialized organizations that have a license to carry out this work.

They are required to adhere to all the standards set out in regulatory documents.

When gasifying populated areas, these organizations strictly comply with the requirements of both special construction standards and regulatory documents of the Ministry of Emergency Situations and power engineers.

Internal networks are those networks that are located directly in the house along with gas equipment.

Gasification standards for a private home every homeowner should know.

In particular, the above documents indicate that when gasifying a private home, the following standards must be adhered to:

• When installing a boiler with a power of up to 60 kW, the height of the room from floor to ceiling must be at least 2.4 meters.
• The glazing area of ​​the room should be 0.03 m2 per 1 m3, but not less than 0.8 m2.
• If 1 (one) boiler is installed, then the area of ​​the room must be greater than or equal to 7.5 m2, if 2 (two) boilers - 15 m2.
• When installing more powerful boilers in the basement of a building, a gas alarm must be installed.
• When installing 2-burner stoves, the kitchen volume must be greater than or equal to 8 m3, and 4-burner stoves - 15 m3.

The process of gasification of a private home also includes examination of chimneys and hoods in case of possible gas accumulation during operation of gas equipment.

Gasification of a private home will solve many problems - not only cooking, but also heating and the presence of hot water.

Gas equipment is practical and convenient to use, and gas supply is the most environmentally friendly compared to other types of fuel.

Nordstroy company from St. Petersburg will help not only quickly and efficiently connect gas to the house, but also draw up all the necessary documents, saving customers from wasting time on submitting them and obtaining all permits.

Gas is the most popular fuel for heating systems. Gas heating is much cheaper than electric heating, and at the same time brings much less hassle than solid fuel counterparts.

However, the process of supplying explosive fuel to a private home requires compliance with a large number of rules associated with both paperwork and significant financial costs.

Laying gas pipelines is a long process and also quite expensive. In order to reduce the cost of the entire process, some installation work can be carried out independently. But for this you need to carefully study the rules and regulations of SNiP.

Procedure for gasification at home

Everyone knows about the flammability, explosiveness, and chemical activity of natural gas, so amateur activity in this situation is out of the question. Gas supply system must be installed exclusively by specialists according to the approved plan.

If you decide to supply gas to your home, prepare for a long paperwork process and be prepared for trips to various authorities with long queues.

Before a team comes to you to carry out installation work, you will have to make a gasification plan, obtain all permits, and only then purchase the necessary gas equipment.

Collection of necessary documents

Before contacting a design organization to create a gasification project for a building, you will have to collect a whole package of necessary documents. Let us note right away that some of the required papers will cost money, so immediately prepare for the financial costs.

So, what papers do you have to collect:

• a document confirming ownership of the house and land;
• copies of identification documents of the owner;
• conclusion on the technical feasibility of carrying out work on gasification of the building;
• technical passport from BTI;
• a topographic map made to a certain scale, which shows all buildings subject to gasification;
• a map showing all laid communications and the planned gas pipeline, which is certified by the gas service;
• if the gas pipeline to the house has to be pulled through neighboring areas, written permission from their owners will be required to carry out the relevant work.

This is an approximate list of documents that you will need to collect.

Depending on certain features, for example, underground or above-ground gasification is planned, it may be necessary to provide some more paperwork.

Preparation of project documentation and conclusion of contracts

Please note that services for the preparation of project documentation are paid. This work can only be carried out by design bureaus that have the appropriate license.

There is no point in trying to create a project on your own, since it must take into account a large number of nuances known only to specialists:

• depth of the central gas pipeline;
• location and depth of gas pipes from the central gas pipeline to the house;
• gasification methods (underground or aboveground). This is influenced by the characteristics of the soil, the depth of groundwater, the interweaving of other communications, buildings, road surfaces, etc.;
• details of installation work;
• connection points for gas appliances and requirements for them in accordance with SNiP;
• materials, joints, as well as the distribution of gas pipes inside the house.

In addition, all project documentation must be certified by the relevant organization.

The cost of the project will depend on the complexity of the project itself, the materials used and the design organization itself. Therefore, it makes sense to consider all possible options, study prices, reviews, and then choose the most suitable agency.

To carry out installation work and put into operation the gas supply system, you also need to conclude the following agreements:

1. Agreement for installation work and preparation of technical documentation.
2. Agreement on gasification and installation of gas equipment.
3. The act of putting the gas pipeline and gas equipment into operation.
4. Inspection report for smoke ventilation ducts.
5. Agreement for the supply and payment of natural gas.

Selecting a contractor and starting installation work

When it comes to gasification of a building, the choice of contractor must be taken with full responsibility. Before concluding an agreement, make sure that the company has the appropriate licenses, contracts, necessary permits, and qualified employees with all the necessary clearances. Installation work to install an underground or above-ground gas pipeline to the building begins after all documentation has been prepared.

However, it is the contractor who will have to provide reports on the work performed and acts that will detail all the actions carried out on the site. Based on these acts, the gas service will have to connect the gas, carry out a series of commissioning works, and then give you a lecture on safety precautions.

Features of materials and gas supply works

When it comes to gas, in no case should you neglect the rules of SNiP for the selection of materials, equipment and features of installation work, since gas is not only explosive, but also toxic.

All materials that will be used in the process of supplying gas to the house and wiring inside the building, from pipes to electrodes, must be of high quality and have appropriate certificates.

For gasification, low-alloy metal or polyethylene pipes can be used. It is worth noting that polypropylene pipes have a number of advantages compared to metal ones: mother weight, ease of installation, ease of transportation, non-corrosion, electrical non-conductivity, reasonable cost, long service life.

1. There are a number of restrictions for laying plastic pipes:

• above-ground gasification cannot be carried out using plastic pipes;
• the use of polypropylene pipes for indoor wiring is prohibited;
• use is prohibited in regions where temperatures drop below -45 degrees;
• prohibited for use on seismically active soils;
• Do not use a plastic pipe to pass through natural or artificial barriers.

1. It is not allowed to embed any welded or gas pipelines into walls or foundations. They must be located so that they are constantly accessible for inspection, maintenance and repair work.
2. Elements of the gas pipeline should not come into contact with flammable elements of the building - door frames, window frames, temporary partitions, etc.
3. Distortions of the gas pipe are not allowed either outside or inside the building. Vertical sections should run strictly vertically, horizontal sections should be laid with a slope of 2-5 mm per meter towards the devices.
4. The gas riser can have a slope of no more than 2 mm. The riser is located in non-residential premises (houses) or along the facade of the building. Under no circumstances should he be in places where people usually are (bedroom, dining room, bathroom).
5. Particular attention should be paid to taps. They should be positioned so that the axis of the plug runs parallel to the wall.

Methods for laying a gas pipeline

The gas pipe from the central main to the facade of the building can pass underground or above its surface. Based on this, underground and aboveground gasification methods are distinguished. It is worth noting that there is often a need to combine these two methods.

So, for example, if a gas pipe has to be pulled across the road, Most often they resort to the above-ground method, so as not to block traffic for a long time. After passing the road, the pipe is deepened underground. However, if new horizontal drilling technologies are used, this need may disappear.

Overhead gas pipeline

An aboveground gas pipeline is much cheaper than an underground one. Savings, in some cases, can be up to 60%. If the gas pipe to the house goes above ground, we will not worry about the depth of groundwater, the intertwining of other communications, or other problems associated with underground work.

However, in this case, pipes laid on must be protected as much as possible from corrosion, deformation, temperature changes and mechanical influences.

In addition, you will have to constantly ensure that unscrupulous neighbors do not connect to your gas pipeline, which, in the case of an underground gas pipeline, is hampered by the depth of the pipe.

Stages of connecting gas to a house (video)

Underground gas pipeline

Although this technology is much more expensive, it is much more popular. When stopping at an underground gas pipeline, you need to remember that the depth of the pipe should be completely comply with the gasification plan for security.

Before the advent of horizontal directional drilling technology, laying gas pipelines underground was associated with a number of problems:

• depth of groundwater;
• seismically active soils;
• passing obstacles and road surfaces;
• soil with a high content of corrosive substances.

However, this technology solved all the problems at once, also reducing the time required to complete the work. Instead of the lengthy process of digging a trench, the depth of which can reach 1.5 - 2 meters, a horizontal hole is drilled from the central highway to the building.

It is only necessary to dig two wells near the pipe, to connect to it, and near the building, to enter the house. The inlet and outlet of the drill are spilled with solution and. In the case of difficult soils, the pipe can be laid in a special protective case.

Gasification of a private house- the process is quite expensive and labor-intensive. However, if you have decided to supply gas to your home, then you need to know what is required for this - what permits are needed to gasify the house, what work will need to be done, and how much it will cost.

Briefly about the main thing

First of all, you need to find out who is the owner of the gas pipeline (usually GorGaz), a meeting with whom will determine the possibility of tapping into its gas pipeline. If you receive a positive response from him, then the next authority will be a design organization that will develop and produce a project for connecting your home to this particular gas pipeline.

Already with the finished project, you are sent to the installation organization, which will take upon itself the solution of all problems related to the installation of the gas pipeline. She is also responsible for commissioning this section of the gas pipeline, so she must have the appropriate license to carry out this type of work. It is advisable to carry out all settlement transactions with the installation organization only after the site has been handed over to the State Control authorities.

When all of the above steps have been completed, and all stages of work have been completed, you can use gas for your own purposes and at your own discretion.

But let's look in order at where to start gasifying your home and what you will need for this.

Documentation required for gasification of a private home

Documentation includes all kinds of acts and documents that confirm your right to ownership of a residential building and land, permission to gasify the house, etc. The paperwork can be divided into two stages - the first stage is the preparation of documents that must be completed before the start of work on laying a gas pipeline to your home and the second stage is the documents that are drawn up during the work process.

First stage. A set of documents for registration of gasification of a house

• permission from the heads of the architectural and planning department (APU) for gasification of a private house;
• a copy of the technical passport of the Bureau of Technical Inventory (BTI) for a private house;
• topographic survey of the site with the planting of the private house and gasified structures on the site on a scale of 1:500 with communications and a gas pipeline, certified by the local gas service;
• written permission from neighbors to connect to the gas pipeline if it is laid on their property (however, as a rule, such permission must be obtained from GorGaz, since in most cases it is the owner of the gas pipeline).

Documents processed during the gasification process

• certificate of inspection of chimneys by the service (in Ukraine - Ministry of Emergency Situations, fire inspector).

Obtaining technical specifications

To obtain technical specifications for gasification, you go to GorGaz.

At GorGaz, you will need to provide a BTI technical passport for house construction, your passport data and identification code number, and also write a corresponding application to receive technical conditions for gasification of your home.

Note:This service is paid, and you can wait for a decision from 14 to 30 calendar days.

Design

Having resolved all the issues in GorGaz, your path lies in the design organization, of which there are a huge number today. Attention! When contacting a particular design organization or design institute, be sure to check whether there is a license to perform this type of work.

The difference in the cost of services sometimes reaches from 10 to 50 thousand rubles (i.e., approximately from $280 to $1,400). But it will be better if you immediately ask GorGaz which design company they recommend, there will be fewer problems later.

If you require a design engineer to visit your home to carry out all the necessary measurements, then please note that this point is stipulated in the contract.

It is with the designer that you agree on the placement of gas appliances in the house and the brand of the desired heating equipment. When the project is ready, the responsible person (designer) will have to approve it with the technical department of GorGaz. This procedure may take from 10 to 14 calendar days.

After completing all the necessary steps described above, you will be able to make calculations and draw up an approximate estimate of all work according to the design documentation. Next, you draw up an agreement for technical supervision and provide a certificate of inspection of chimneys by the VDPO service (in Ukraine - the Ministry of Emergency Situations, fire inspector).

Agreement with construction and installation organization

When all the necessary documents have been signed and all matters with GorGaz and the design organization have been settled, you are sent to the installation organization, which will subsequently carry out all the necessary construction and installation work. Don’t be shy to also check her license, since it is the installation organization that must hand over the work to GorGaz, so its existence should be evidenced by an entry in the GorGaz register.

Note:in most cases, installation organizations have a license to perform not only installation, but also design work, in this case, if you order the project directly from the installation organization, the cost of gasifying a house is reduced by 25-30% of the total amount.

When you have agreed on the terms and cost of the work with the installers, be sure to sign an agreement with them so that if something happens, you have at least some guarantees from the contractor.

The contract will specify guarantees and obligations on the part of the installation organization.

Guarantees during the installation of external and internal gas pipelines:

• when carrying out construction and installation work, the contractor must have all the necessary fire extinguishing means available, as well as a protective screen necessary to protect the surface of the walls from heating;
• after final payments for the work performed, the installation organization hands over the as-built and technical documentation to you;
• The construction and installation organization undertakes to perform all work under this contract in a timely and high-quality manner.

During the commissioning process:

• establish optimal modes of gas equipment to ensure rational use of gas;
• instruct you on the correct use of the equipment;
• if it is impossible to debug the operation of gas equipment or individual components, establish the reason for this impossibility, record it in the act and suspend work until the identified deficiencies are eliminated;
• hand over the result of the work with the execution of a bilateral certificate for the work performed.

Drawing up executive and technical documentation

The installation of the gas pipeline has been completed, as well as all the necessary equipment, then as-built technical documentation is drawn up, and the installed gas pipeline is accepted by a special commission consisting of the customer, the contractor and a representative of GorGaz.

The period for acceptance by the commission can range from 14 to 30 working days. If no comments were made, the GorGaz representative will issue you a technical supervision receipt, which you will have to pay for and then give a copy to the installation organization. The average payment is about 1,500 rubles ($43).

Please note that at the time of acceptance, all equipment listed in the project documentation must be not only installed, but also connected. After the commission, the installation organization will prepare and submit to GorGaz all the necessary technical documentation, where it will be stored.

Based on the decision of the commission and upon provision of all documents to GorGaz, within 21 working days the meter will be sealed and an agreement will be concluded with you for the supply of gas, as well as for further maintenance of both the gas pipeline itself and the gas equipment located inside the house.

Safety briefing

When the entire list of actions listed above is left behind, you will be required to undergo safety training when using gas.

You can undergo the briefing directly at GorGaz, where you will be instructed by a safety (safety) engineer. After the briefing, you sign in the logbook, which remains at GorGaz.

You can also be instructed at home by a certified specialist to conduct safety instructions during commissioning of gas equipment. Just as after the briefing in Gorgaz, you sign in the safety register; this journal will subsequently be transferred to GorGaz.

Connection to the main gas pipeline

In order to tie your gas pipeline into the main gas pipeline, you must first pay for the work that will be performed by a special tie-in service, with which you will also have to first agree on the terms.

After tapping in the gas, representatives of the regional gas service open the gas tap and test-run gas to the appliances, thus checking for leaks (this service is paid - on average, the cost of such a service can be 3,000 rubles ($84)).

Commissioning works

After starting the gas, you will need to contact the organization with which you signed a service agreement for all provided gas equipment so that it can put this equipment into operation. This will be one of the most important conditions for warranty service of your equipment during the periods specified in the warranty service agreement (what warranty period will be established depends on your place of residence, on average the warranty period for service of gas equipment ranges from 1 year to 3 years)

You will also need documents to perform a thermal engineering calculation, which will help determine the required boiler power to provide heating and hot water supply to a private home (for this you can contact specialists from the housing and communal services):

• floor plans of all heated rooms of the house with explication, as well as an indication of heights and areas;
• types and numbers of hot water intake points (such as washbasins, bathtubs, showers, etc.);
• description of the possible use of a gas boiler for technological needs.

The owner of a private house has the right to make all approvals either independently or contact an organization that deals with issues of gasification of the house and installation of a gas pipeline.

Types of gas pipelines

Now that you have become familiar with the conditions for gasifying your home, let’s consider what types of gas pipelines exist and which one to choose for gasifying your home.

Based on their location relative to the surface of the earth, gas pipelines are divided into underground and aboveground, which are distinguished by the method of introducing into the building both the internal gas supply networks and risers that serve to distribute gas across the floors of the house, as well as all gas-consuming appliances.

Underground gas pipeline

It is known that construction underground gas pipeline costs much more (about 60%) than aboveground. But, nevertheless, such a high cost (1 linear meter of laying an underground gas pipeline costs approximately 1,300 rubles ($36.6)) does not make the underground gas pipeline less popular. This is because a pipe running in the ground is much more protected than a pipe running through the air, which means it will last much longer. Moreover, it is less hazardous to the environment.

When laying an underground gas pipeline, it is necessary to either completely block traffic or limit travel on certain sections of the road. To do this, the organization performing the installation work, based on the design documentation it has, draws up location-specific traffic management diagrams for both vehicles and pedestrians, as well as the placement of equipment, indicating the geometric parameters of the desired area and entrances to houses, detours and road placement locations. signs.

Schemes for organizing traffic and fencing work sites for laying an underground gas pipeline are coordinated with the department of the State Road Safety Inspectorate (STSI), which issues a warrant to perform this type of work.

Overhead gas pipeline

Concerning overhead gas pipeline, then it has both its advantages and disadvantages. For example, open sections of a gas pipeline are more susceptible to corrosion, and it is easier to connect to such systems without permission. Underground gas pipelines are considered more reliable, but their repair is accompanied by additional costs.

Let's compare two types of gas pipelines to make it easier for you to make your choice - which of these types is most suitable for you:

• if in the area where you live, the soil has high levels of corrosion, then in this case it is appropriate to lay an overhead gas pipeline;
• if there is a high-voltage power line near the place where the gas pipeline is laid, then in this case the best option would be to lay an underground gas pipeline;
• if the gas pipeline runs along a neighboring land plot, then in order to avoid damage to the fertile layer of soil along the entire gas pipeline line leading to your house, it is best to choose the laying of an above-ground type of gas pipeline, in this case it will be easier to obtain permission from neighbors to lay the gas pipeline along their land plot;
• If you have to lay a gas pipeline across the road, then in this case you can choose a combined option: an underground gas pipeline is laid across the road, and an overhead gas pipeline is laid along the land plot.

Material for gas pipelines

Now knowing what types of gas pipelines there are, in this part we will consider the question of what types of pipes are used when laying a gas pipeline.

Just 10-15 years ago, gas pipeline pipes were made only of steel. Today, polyethylene pipes are in great demand, which not only are not inferior in their properties to steel pipes, but also have a number of advantages:

• such pipes have increased resistance to the negative effects of various chemical compounds and environmental factors;
• they are durable and at the same time quite flexible, which makes it possible to lay a gas pipeline in areas with particularly harsh climatic conditions.

Note:at low temperatures down to -45 degrees, polyethylene does not lose impact strength.

• Since plastic is not a conductor of electric current, such pipes are absolutely insensitive to the effects of stray currents and, therefore, have reliable protection against electrochemical damage. Therefore, plastic pipes do not need additional protection before they are laid in the ground;
• The weight of plastic pipes is 7 times less than steel. Moreover, they are supplied in special compact bays, which greatly simplifies their transportation;
• installation of such pipes is simple and convenient;
• The warranty period for plastic pipes is 2 or even 3 times longer than steel pipes, and is more than 50 years.

Important! Gas pipeline pipes are introduced into the house only with steel pipes, as is the gas pipeline installation inside the house.

But gas pipelines made of polyethylene pipes have not only advantages, but also restrictions on their use for the installation of gas pipelines, which are stipulated by SNiP 2.04.08-87. Below are some of the restrictions on constructing a gas pipeline using polyethylene pipes:

• the construction of a gas pipeline made of polyethylene pipes is prohibited in areas where the temperature of the outside air reaches below minus 45 degrees;
• It is also prohibited to install gas pipelines using polyethylene pipes in areas where seismicity exceeds 6 points;
• the installation of gas pipelines using polyethylene pipes is prohibited both above and above ground, as well as inside buildings, in tunnels, collectors and canals;
• on land plots where it is planned to construct crossings through artificial and natural barriers, laying a gas pipeline from polyethylene pipes is also prohibited.

Selecting a heating boiler

Having considered issues related to the conditions of gasification at home and types of gas pipelines, it is necessary to consider another equally important issue of gasification - the choice of a heating boiler.

As for choosing a boiler, today the modern market offers many different gas heating boilers. They are divided into floor and wall.

Floor standing gas boiler

A distinctive feature of floor-standing gas boilers is the enormous possibility of choosing the power of equipment that is able to heat more than 150 m2 of space. With the additional installation of a boiler, a gas boiler will provide maximum hot water supply.

Wall-mounted gas boiler

Wall-mounted gas boilers are distinguished, first of all, by their compactness, built-in automatic security system, the presence of an expansion tank and circulation pumps, as well as a relatively low cost. They are usually designed to heat a room with a total area of ​​up to 150 m2 and provide up to 2 taps with hot water.

Heat exchanger material

As for the material from which heat exchangers in boilers are made, it can be cast iron or steel.

Heat exchanger made of cast iron characterized by a long service life (the service life of a gas boiler with a cast iron heat exchanger is 20-25 years, and a boiler with a steel heat exchanger is 10-15 years) due to its high corrosion resistance.

As a rule, the heat exchanger is made of cast iron in sections, which allows, in the event of an accident, not to dismantle the entire boiler, but to isolate only those areas that were damaged. Keep in mind that a boiler with a cast-iron heat exchanger is highly sensitive to both mechanical and thermal shocks, so make-up with cold water should be carried out only after the heat exchanger has completely cooled.

Gas boiler with steel heat exchanger compared to a boiler with cast iron heat exchanger has much less weight and a lower price. A boiler with such a heat exchanger is not afraid of mechanical stress, but is susceptible to corrosion.

Note:a boiler with a cast iron heat exchanger weighs from 114 kg and costs from 30,000 rubles ($845), and a floor-standing boiler with a steel heat exchanger weighs from 60 kg and costs from 12,000 rubles ($340).

Non-volatile and volatile boilers

Non-volatile boilers, characterized by natural circulation, have a number of disadvantages: the large diameter of the pipeline itself, the presence of an open expansion tank, and the peculiarities of installing the system to ensure its slope, but the most important thing is the inability to regulate the air temperature in the room. In this case, the room in which the boiler with an open combustion chamber will presumably be installed must have both tidal and exhaust ventilation and a chimney.

Concerning volatile boilers, then they have a closed expansion tank, circulation pumps and full electronic boiler control automation. Thus, they can rightfully be considered a mini-boiler room. However, it is necessary to take into account the fact that the uninterrupted operation of the entire heating system must be ensured by a stable network voltage of 230±10% in the presence of a voltage stabilizer.

Only a specialist can decide on the choice of a gas boiler, its power, as well as designate the piping diagram and determine the need for additional automation. To calculate the approximate power of a gas boiler, you can make calculations based on the fact that per 10 sq. m of room requires 1 kW of boiler power + from 15% to 20% of the reserve, designed to extinguish unforeseen heat losses.

Note: to calculate heat loss, you can ask a question in the section.

As for the removal of combustion products in gas boilers, this process can occur either naturally or forcedly (turbo). In boilers with natural draft, gas is removed due to draft in the chimney; in boilers with forced draft - using a fan built into the boiler.

Gas boilers with a “turbo” system are in most cases installed in facilities that do not have a traditional chimney. Then specialists install a coaxial chimney, which is a kind of “pipe within a pipe” leading out into the street through the wall.

Coaxial chimney

The outer pipe is designed to supply air, and the inner pipe is to remove combustion products. A gas boiler with forced draft is also installed in a house where it is undesirable to once again take air from the room.

What you should pay attention to when installing a coaxial chimney outside:

• the chimney pipe must be at least 2 m from the ground surface;
• even during the design of the gas pipeline, if you have a boiler with a coaxial chimney installed in your house, you should pay attention to ensure that the combustion products from the boiler do not flow back into the open windows back into the house;
• It should also be taken into account that condensation can form in a coaxial chimney; to remove condensate, it is necessary to install the coaxial chimney at an angle of approximately 2 degrees with a slope to the ground surface;
• the coaxial chimney must have unhindered discharge of combustion products to the street; for this it is necessary that the distance from the end of the outer part of the chimney to the buildings located next to the house be at least 1.2 - 1.5 m.

Boiler room at home

As you know, the main condition for the combustion of natural gas is its complete combustion, which occurs only with a sufficient amount of oxygen. Therefore, the room parameters must be sufficient for installing a gas boiler.

The most suitable place for installing a boiler in a private house is, perhaps, only a special separate room with a window with a window or transom, a chimney, as well as tidal and exhaust ventilation. For air flow, a grille or a special gap with a cross-section of at least 0.025 m2 should be provided at the bottom of the door. For boilers whose power reaches 30 kW, an ordinary kitchen can serve as such a room.

Boiler on the kitchen wall

In the room provided for a gas boiler, there must be a water supply system, a drainage ladder and a gas alarm. The latter will help control the microconcentration of carbon monoxide and send a signal to an individual warning alarm system, which, if the required level is exceeded, will shut off the gas supply. The room must also have an exhaust hood.

Hood power calculation

M = (SxHx12) + 30%, Where:

• M - exhaust power;
• S - kitchen area;
• H - ceiling height in the kitchen;
• 12 - every hour (according to SES standards) the air in the room where the gas boiler is located must be renewed up to 12 times;
• 30% is the minimum power reserve required for effective air purification.

Example of hood power calculation

In the room where the gas boiler is installed, the area is 7 m2, the ceiling height is 2.5 m.

The exhaust power required for such a room is:

M = (7x2.5x12) + 30% = 273 m3/hour

Note: it is necessary to take into account the fact that 30% of the power reserve is only sufficient if the hood is located directly above the boiler. In other cases, when calculating the exhaust power, you should add another 15% for each turn of the air duct pipe and another 10% for each meter of the air duct.

It is not allowed to install more than two small-sized boilers in one room of a private residential building. The volume of a room intended for heating equipment with a total thermal power of up to 30 kW must be at least 7 m3, while the duration of people’s stay in this room during the day should not exceed 4 hours.

Boiler room dimensions

As for heating gas equipment with a power from 30 to 60 kW, it is necessary to provide for it a separate non-residential room, built-in or attached to the house, the total volume of which must be at least 7 m3; for boilers with a power from 60 to 200 kW, the volume of such a room must be at least 11.5 m3.

The place provided for installing the boiler is specially separated from adjacent rooms by enclosing partitions with a fire resistance limit of 0.75 hours, while the fire spread limit over the entire area of ​​the structure must be zero. Such partitions are made to cover the entire height of the boiler, and the height of the room must be at least 2.5 m.

The walls and floor of a separate boiler room must be fire-resistant and not a source of dust. One of the most optimal solutions for creating and maintaining cleanliness in a boiler room will be tiling the walls and floors with ceramic tiles, as well as coating them with oil paint. Since it is dust that leads to the deposition of contaminants on the burners and in the heat exchanger channels, which largely reduces the performance of this heating equipment.

Diagrams of distances from the boiler to other structures in the house

A. The distance from the top of the boiler to the unprotected ceiling must be at least 120 cm. The distance from the outer surface of the boiler or pipe to the wall or partition is at least 32 cm (if the building structure is protected by a metal sheet against asbestos, then the distance can be from 26 cm) .

B. The distance from the inner surface of the pipe to the combustible structure should be less than 50 cm (if it is protected by a metal sheet over asbestos cardboard with a minimum thickness of 8 mm or plaster with a thickness of 25 mm over a metal mesh, then this distance should be from 25 cm).

It is also necessary to take into account the parameters of the location of the gas pipeline relative to the house electrical network. For example:

• the distance of the gas pipeline from the electrical panel must be at least 30 cm;
• from electrical wires that are laid in an open way - at least 25 cm;
• from hidden wiring - about 5 cm.

All safety parameters indicating the location of gas heating equipment in centimeters are clearly stated in the installation instructions for each individual boiler model.

An important condition for the uninterrupted operation of gas heating equipment are chimneys for boilers with natural ventilation. They can be internal, i.e. pass through the ceiling and roof of the house itself, and externally - mounted along the outer surface of the wall.

The choice of the most optimal chimney should be carried out by a specialist. You just need to know that the internal diameter of the chimney must be no less than the diameter of the boiler neck; there should be a minimum amount of various bends and elbows in the path of flue gases; When installing a chimney, it is imperative to take measures to prevent the formation of condensation.

Scheme of raising the chimney above the house

The chimney should be raised 50 cm above the top of the building. If the roof of the house is made of flammable materials, then the chimney should be installed above the ridge of the roof by 1, or even 1.5 m. The elevation of the chimney is also affected by the presence of taller buildings located nearby.

Places to seal the chimney in the house with heat-resistant sealant

In order to avoid smoke leakage into the heated room, all junctions of the chimney modules with each other and with the boiler itself are specially sealed with heat-resistant sealant.

To ensure uninterrupted operation of modern heating boilers, high-quality chimneys are required, which can prevent the occurrence of such problems as the destruction of brickwork, the appearance of greasy stains on the walls and ceiling of the boiler room, the penetration of carbon monoxide into the heated room, etc.

The best option in terms of price/quality ratio are chimneys made of stainless steel. They come in single and double layers. The first ones, as a rule, are used for laying a chimney indoors. However, they have a significant drawback - abundant condensation, which appears when flue gases are removed from modern gas heating structures with high power.

Double-layer insulated stainless chimneys, as you understand, consist of two layers of steel, between which insulation is placed, which can significantly reduce the amount of condensate formed.

Please note that when choosing a chimney, it is necessary to take into account the power of the boiler, the temperature of the combustion products, the material of the shaft and its insulation, as well as many other points that affect the draft, durability, reliability and safety of the chimney.

Note:if the boiler has a power of up to 60 kW, then it is enough to make a chimney from non-combustible materials, for example, from roofing steel, but if the boiler power is 60 kW or more, then it is best to make the chimney riser from brick.

As for the cost, design work for gasification of a house, which is carried out by special design institutes, will cost you somewhere around 5 thousand rubles (about $140). Today, 1 meter of pipeline costs between 800 and 1,300 rubles (i.e., approximately $22.55 and $36.6 for above-ground and underground gas pipelines, respectively).

It is difficult to name the exact cost of installation work, since it depends on many indicators: the number of holes in the walls of a private house, the diameter of the gas pipeline itself, the number of bends, etc.

Thus, to carry out gasification of a private home, it is necessary to count on an amount from 110 to 145 thousand rubles, i.e. approximately $3000-4000 (the indicated amount includes the cost of the boiler itself, as well as all construction and installation work, wiring around the house and installation of an individual gas control system).

And so, now we know what the process of gasification of a private house includes:

• development of project documentation;
• introducing a gas supply system to the house from a street gas pipeline;
• installation of gas networks inside the house itself;
• cost and installation of gas equipment.

Heating using a gas boiler implies the ability to independently set and regulate the temperature in the room, which means it allows you to feel comfortable and cozy in it.

APPLICATION

After studying the article on gasification of a private home, it will be easier for you to supply gas to your home, since you have the necessary information and know in advance what you need to do.

But let's go back to the section “Gasification - step by step” (Documentation) and look at some documents with tips that will help you complete these documents as quickly as possible:

• an inspection report of chimneys by the service (in Ukraine - the Ministry of Emergency Situations, a fire inspector) of the All-Russian Voluntary Firefighting Society (VDPO);

Advice: before inviting a VDPO or Ministry of Emergency Situations specialist to your place, you should prepare the room - equip it with an exhaust hood (if it does not already exist), the room should be isolated from other rooms in the house - pay attention to the fact that the entrance to the room must be closed, and the door was without glass.

Also, if your chimney is made of brick (riser), then it is necessary that its internal cross-section is no less than the diameter of the chimney outlet of the gas boiler. The riser must have a vent with a tightly closing door (through the vent, the inspector will use a mirror to check the internal condition of the chimney and its size).

• written permission from neighbors to connect to the gas pipeline if it is laid on their property (however, as a rule, such permission must be obtained from GorGaz, since in most cases it is the owner of the gas pipeline);

Advice: if the gas pipeline to your house from the main gas pipeline will have to be laid through a neighboring plot, then you need to discuss this with its owner, even before submitting an application for gasification of your house, since in some cases the solution to this issue may not be obtained so quickly. And without the permission of the owner of the site through which the gas pipeline will go to your house, the GorGaz service cannot begin work on its installation. If the issue is resolved and the neighbor has given consent, then be sure to confirm it in writing (free form) addressed to the manager of GorGaz and attach a copy of it to the application.

Basically, the issue of running a gas pipeline through a neighboring plot is resolved privately by agreement of the parties (for example: a one-time cash payment to the owner of the plot for running a gas pipeline through its territory).

• documents for gas equipment that will be installed in the house (certificate of conformity, permission to use this equipment on the territory of your place of residence, an agreement for further maintenance of this equipment);

Advice: When buying a gas meter, you should pay attention to the following points - if you buy the meter yourself, then its brand must strictly correspond to the one that will be indicated in the project documentation. A technical passport is attached to the meter - you should check that the serial number indicated in the passport matches the number on the meter. Since if the numbers do not match (this happens), you will have difficulties registering it with GorGaz and commissioning work will be postponed until you eliminate the inaccuracy in the documentation for the meter.

Attention! The prices given in this article were current as of 2009.

Connecting gas to a private home is the key to comfort and coziness. Without high-quality heating, heating a private house in winter is quite problematic, and a gas boiler is rightfully considered one of the most reliable and economical solutions. Even if gasifying a house will cost a tidy sum, it is not worth saving on this, since in most cases the benefits compared to alternative heat sources are obvious even with superficial calculations. In addition, gas is one of the most convenient energy carriers. It is very convenient to cook food on a gas stove, and the boiler will quickly and efficiently warm up the house. When and how to properly install gas into a private home, the price of the work will be disclosed in our article today.

A gas stove and boiler are one of the most effective devices for cooking and heating a home.

What can gas supply be like?

It is possible to provide a private home with “blue fuel” according to two schemes.

• Connection to the gas main. If there is a gas pipeline along the street on which the house is located, then you can contact the appropriate service and they will draw up a project for you and carry out the connection. The easiest way to find out where to go is to ask your neighbors who have already been supplied with gas. You can also walk along the pipe and find the distribution station - usually the phone numbers of the service company are written on it. As a last resort, you can call the 104 service, but it is better to first ask your neighbors for the required number;
• But there are places where connecting to the gas main is impossible. These are mainly remote villages and dachas located away from the central villages (for example, on the shore of a reservoir). But even in this case, there is a way out - these are gas tanks. Systems designed to store relatively small gas reserves (from 2,500 m3 to 20,000 m3). These systems provide a residential building with gas year-round; you only need to replenish the reserves of “blue fuel” 1-2 times a year. Many specialized companies have already opened that will help you correctly calculate the volume of a gas tank, prepare permits, and install it in the right place.

Gasification of a private or country house - where to start

The first thing you need to start with gas supply to a private home is technical documentation. You need to contact the appropriate authority that deals with such issues in the area. A special commission will determine the condition of the tenant and the possibility of carrying out installation work. After this, specialists will develop a project, it will be approved by the permitting authority, and workers of the gas industry or a company that has permission for such work will begin the connection process. Before the project is developed, they will only be able to tell you approximately the cost of connecting gas to a private home, since the final price of materials and services consists of many components.

If there is already a gas main near the house, then you will only have to pay for the connection to the pipe - otherwise, the cost of the project most often includes work on laying the line along the street

On our website you can find contacts of construction companies. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.

What documents will be required

It must be remembered that some documents must be ready before installation work begins, and some can be completed during the process, therefore, if it is not possible to complete all the documentation at once, then you need to determine priorities in advance.

Here list of documents, which must be submitted to the relevant authority in order to be allowed to supply gas to a private house:

1. Application in writing. This will begin the preparatory work (analysis of the area, building, etc.);
2. Provide copies of documents that identify the customer (the originals must be presented with copies);
3. Provide copies of documents that confirm the right to own the house (also present the originals for comparison with copies);
4. If the gas pipeline runs through the neighbors’ area, their consent will be required;

Subsequently, you will need documents for the equipment that will be connected to the gas, and the results of the chimney inspection.

You can collect and provide all the necessary documents yourself, or entrust this to other persons by issuing an appropriate power of attorney for them.

Connection diagram is one of the required documents

How to make a home gas supply plan (gasification project)

A gas supply project for a private home is a necessary component for starting all work. Gas-consuming installations are potential sources of danger and compliance with safety regulations is required.

To draw up the correct gas supply plan for your home, specialists need to thoroughly know all the points of the regulatory documents and strictly follow them. The technical department of the gas industry always checks the compliance of the plan with the requirements of regulatory documents and, if necessary, returns them for revision.

The requirements that gas utilities place on projects may vary depending on the terrain, installation method, and installation conditions. It may take several weeks or even months to thoroughly test the plan.

Projects must be strictly individual; plans that were developed for other houses are prohibited from being used by law, and criminal liability is provided for this.

The project must indicate the layout of the house and the location of gas equipment

The stages of connecting gas to a private house will vary in each specific case, as they depend on the topography of the site and individual features of the gasification plan.

How a gas pipeline is built (connecting a gas line to a house)

With an approved project, you must contact a company that deals with similar work (necessarily with a state license). If the estimate drawn up by the company suits both parties, then an agreement is concluded to carry out the relevant work.

The contract must indicate that the final payment will be made only after all work has been completed and accepted by the official commission.

Upon completion of installation work, as-built production and technical documentation is drawn up, which must be approved by the commission. After successfully connecting the gas line to the house, you can immediately conclude an agreement for the installation of the equipment that will be connected (boiler, stove, etc.).

Commissioning work must be carried out exclusively by gas specialists

Completion of gasification (gas connection to the house) is also an important stage

At the final stage of gasification of the house, all that remains is to undergo training on the safe use of gas equipment, conduct a test run, and conclude an agreement for seasonal maintenance of the system. If a gas tank is installed, then it is necessary to conclude an agreement for systematic gas supplies.

The final “touch” is to give the design documentation (or an approved copy) for safekeeping in the archive, in case redevelopment is later required or any clarifications are required.

What has changed in the rules for gasification of a private home?

Until 2016, it was quite difficult to even roughly predict how much it would cost to connect gas to a private home, since there was no legislative regulation and control. This led to the fact that monopolists could independently set the timing of gasification and its cost. But, with the adoption of new laws, the maximum period for gasification was limited to one and a half years.

It is difficult to name the specific amount that all the work will cost without a ready-made project, but at least the price bracket has been fixed at 20-50 thousand rubles for bringing the gas pipeline to the site, plus installation work inside it.

The cost and timing of approval and implementation of a private home gasification project are now regulated by law. This means that the party ordering the services can now take a more active role in monitoring the work and demand that it be completed on time.

What other questions arise about the cost of connection are described in the video:

Conclusion

Although gasification of a private home is a long, tedious, and expensive process, its importance cannot be overestimated. Everyone who has the opportunity to gasify their home does so first, especially since with the adoption of new laws the population has the opportunity to predict the timing of the work.
