How to make a project for the gasification of a private house with your own hands and approval: technical conditions

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Houses in the private sector can be heated using various types of boilers. It can be electric, diesel, solid fuel and, of course, gas. Most of the owners of private houses prefer to install gas equipment.

The reason for this is the price - gas is the most inexpensive fuel. Of course, the gasification process itself is an expensive pleasure.

But savings on heating bills will quickly cover the cost of installing gas equipment.

In the event that you have firmly decided to gasify your house, you need to know what you need for this: permits, what work to be done, the price of this issue.

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Everyone understands what to gasify a private house necessary subject to certain rules and regulations.

As a rule, the gasification process in a given settlement will be carried out in the presence of a laid pipeline.

In this case, the project will include 2 points:

  1. the procedure for connecting to it
  2. calculating the duration of the pipes that will be required to supply gas to home itself.

In the absence of a mains in your settlement, an autonomous gasification project can be developed. In this state of affairs, plus the above, it is necessary to determine the location of the gas tank, as well as the existing methods of connecting the boiler to it.

Requirements for gasification of the house

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Gasification the private sector is carried out in accordance with the standards established by law.

You can get permission to crash into the highway, or you can connect if all the conditions are met:

  • you own the house and the plot as property;
  • there is a room in your house that is suitable for the installation of the boiler according to the established requirements.

There are also certain requirements for the room where a boiler with a capacity of up to 60 kW will be installed:

  • this is a non-living room, often it can be How to make a project for the gasification of a private house with your own hands and approval: technical conditions be a kitchen or a specially designed room
  • the boiler can be installed on any of the floors, the basement volume is not excluded
  • premises must be equal to or greater than 15 cubic meters.

    meters. The permissible deviation is 20 cm to one or the other side

  • The ceiling height can be at least 2 m 50 cm
  • There must be a window with a window
  • at least three times the volume of the hood.

If all the above conditions are met, we proceed to collecting documents for gasification.

You will need:

  • a copy of the technical passport for the house issued by the BTI
  • documentation for all the gas equipment you purchased. How to make a project for the gasification of a private house with your own hands and approval: technical conditions

Next, you need to visit the following instances:

  • First on the list is a visit to your local planning office.

    They are in charge of gasification of private houses.You need written permission from this organization.

  • the next visit will be a visit to the fire service or housing and communal services. This is followed by a call to the house of an inspector who will inspect the chimney. After that, subject to all requirements, that is, the presence and operability of the chimney, the inspector issues the owner an appropriate act.

  • the next on the list will be a visit to the local Gorgaz or Oblgaz branch and obtaining technical conditions for conducting gas into the house. In this instance, you need to write a statement on the form provided. It will require an indication of the approximate consumption of gas per hour. Such an application is considered for 2 weeks. After that, the owner will receive technical specifications.

After reading the documents, it will be useful to know what types of gas pipelines exist, their advantages and disadvantages.

According to how the gas pipeline will be located relative to the ground, underground and aboveground are distinguished, their difference is in the method of entering into the building not only internal gas supply networks and risers, but also all gas-consuming devices.

Consider an underground gas pipeline

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Build a gas pipeline more expensive underground than above ground (about 60%) . But he is not losing his popularity. The explanation for this is quite logical - such pipes have the greatest protection, compared to aboveground ones, and a longer service life.

They are less dangerous for the environment.

It should be borne in mind that when laying an underground gas pipeline, either partial restriction of traffic on a separate section of the road or complete blocking of traffic is required. For this, the necessary diagrams are drawn up by the installation organization. The next step will be to agree with the traffic police department of the traffic restriction scheme and barriers to the places where the gas pipeline will be laid. After passing the approval procedure, an order is issued to perform this kind of work.

Gas pipeline above the ground

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Second view - a gas pipeline laid above the ground, which also has its pros and cons. The negative side of such a gas pipeline is the susceptibility to corrosion of open sections of the gas pipeline, as well as the ease of unauthorized connection. In this regard, an underground gas pipeline is considered reliable.

Let's compare the two types of gas pipeline, because knowing some of the nuances, you will make the right decision:

  1. When it is known that in your settlement, the soil is characteristic high indicators of corrosiveness, in such a situation it would be most correct to give preference to an aboveground gas pipeline.
  2. If your house is located near a high-voltage transmission line, in this situation it is worth giving preference to the installation of an underground gas pipeline.

  3. In the case when, when laying a gas pipeline underground, it is necessary to lay a gas pipeline throughout the entire section of neighbors in order to avoid unnecessary misunderstandings and obtain permission from neighbors, it would be appropriate to choose an aboveground type of gas pipeline.
  1. In a situation where the gas pipeline will be laid across the road, it is possible to combine the gas pipeline: make the section under the road underground, and on the land plot - above ground.

When giving preference to one or another type of gas pipeline, it is worth understanding which pipes are used for laying the gas pipeline. In the recent past, the pipes for the gas pipeline were only steel. Today, polyethylene pipes have gained popularity; they do not lose at all to steel ones.

Types of pipes for a gas pipeline

Plastic pipes are characterized by many advantages: How to make a project for the gasification of a private house with your own hands and approval: technical conditions

  • They have increased resistance to the negative effects of various chemical compounds, as well as environmental factors.
  • Their strength is combined with sufficient plasticity, which makes it possible to lay a gas pipeline in settlements with a particularly harsh climate (at temperatures up to minus 45 ° C, such pipes retain impact strength).
  • T. Since plastic does not conduct electric current, polyethylene pipes are insensitive to the action of stray currents, which means they have reliable protection against electrochemical damage. It is for this reason that such pipes do not require additional protection when laid in the ground;
  • The mass of polyethylene pipes is seven times less than steel.

    What is important, they are delivered in special compact coils, which greatly simplifies transportation;

  • It is easy and convenient to install these pipes
  • The service life of polyethylene pipes exceeds that of steel pipes by two, and sometimes three times of years, and reaches 50 and more years.

Remember! The introduction of pipes into the house and their distribution in the house is carried out only with steel pipes.

As with all goods, polyethylene pipes have certain restrictions:

  • In areas where the air temperature falls below 45 ° C, as well as in areas with seismicity exceeding 6 points, it is forbidden to use polyethylene pipes when laying a gas pipeline;
  • It is prohibited to use polyethylene pipes when laying a gas pipeline both above the ground and on the ground, in channels, tunnels and collectors, as well as in buildings;
  • It is prohibited to lay a gas pipeline from such pipes in the area where it is planned to arrange crossings over artificial or natural barriers.

Types of boilers or how to make the right choice?

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Next, it is worth considering the types of boilers in order to make the right choice. The modern market provides a huge selection of gas equipment.

There are two types of boilers: wall-mounted and floor-standing.

The wall-mounted gas boiler is distinguished by its compactness, built-in automatic security system, the presence of an expansion tank and circulation pumps, and, importantly, a relatively low cost.

Usually, their purpose is to heat a room, the total area of ​​which is no more than 150 sq. meters and providing two taps with hot water.

A distinctive feature of floor gas boilers - ample opportunities for choosing the power of equipment, the function of which will be to heat a room over 150 sq.

meters. Such a boiler will be able to ensure the proper supply of hot water when the boiler is additionally installed.

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Heat exchangers in boilers are made of cast iron or steel. A cast iron heat exchanger has a long service life (approximately 20 to 25 years, in comparison with a steel one from 10 to 15 years), which provides a high rate of corrosion resistance.

The cast iron heat exchanger usually consists of sections, this gives an advantage in case of an accident.

That is, not the entire boiler is dismantled, only damaged areas are insulated. It must be remembered that such a boiler is characterized by high mechanical and thermal sensitivity. In this regard, it is possible to recharge with cold water only if the heat exchanger has completely cooled down.

How to make a project for the gasification of a private house with your own hands and approval: technical conditions A gas boiler with a steel heat exchanger, when compared with the above boiler, has cost advantages and is lighter in weight ..

. A distinctive feature of a boiler with a steel heat exchanger is resistance to mechanical stress, but a negative feature is susceptibility to corrosion. The weight of a boiler with a cast iron heat exchanger is 114 kilograms, and the weight of the same boiler with a steel heat exchanger is about 60 kilograms.

Another type of boilers - non-volatile and volatile.

Boilers with non-volatility, characterized by natural circulation, but at the same time have an impressive list of disadvantages:

  • the pipeline itself has a large diameter,
  • there is an open expansion tank,
  • a special installation of the system is required to ensure the desired slope,
  • the largest - there is no possibility of adjusting the air temperature in the house.

At the same time, the room in which the boiler is supposed to be installed with an open combustion chamber must be provided with tidal and exhaust ventilation, as well as a chimney.

How to make a project for the gasification of a private house with your own hands and approval: technical conditions If we talk about volatile boilers, they are equipped with a closed expansion tank, circulation pumps and full electronic control automation boiler. In this regard, they can undoubtedly be called a mini-boiler room . But at the same time, an important fact should be taken into account that ensuring the uninterrupted operation of the entire heating system depends on a stable network voltage of 230 ± 10% in the presence of a voltage stabilizer.

For boilers with natural ventilation, a chimney becomes a prerequisite for the smooth operation of gas heating equipment.

They are internal, passing through the ceiling and roof of the house itself, as well as external, which are mounted along the outer surface of the wall.

Only a specialist can select the optimal chimney

How to make a project for the gasification of a private house with your own hands and approval: technical conditions For the consumer only you need to know a few simple rules:

  • the diameter of the boiler neck should not be more than the inner diameter of the chimney;
  • the minimum number of all possible bends and elbows in the path of flue gases;
  • it is imperative when installing the chimney to ensure conditions that exclude the formation of condensation

Chimneys made of stainless steel are optimal in terms of quality and price ratio.

They can be single-layer or double-layer. Single-layer are used for laying the chimney indoors. Their significant drawback is the formation of abundant condensate, which is formed when using modern heating gas installations to remove flue gases.

Two-layer chimneys, made of two layers of steel, the space between which is filled with insulation, such a device reduces the amount of condensate formed.

It must be remembered that the choice of the chimney depends on the boiler power, the temperature of the flue gas outlet, the material of the shaft and its insulation, as well as other factors affecting such indicators as draft, safety, durability and reliability of the chimney ...

When we have decided on the equipment, we start developing the project

How to make a project for the gasification of a private house with your own hands and approval: technical conditions This issue is dealt with either by Gorgaz employees or design engineers of any specialized organization .

Development of the project includes drawing up a scheme for laying pipes to the house, determining the place of entering the highway into the house.

The cost of the procedure depends on the length of the pipes that will be used to connect your house to the gas pipeline.

In case of autonomous gasification, which is carried out with the help of a gas holder, the project determines the place of its installation.

How to make a project for the gasification of a private house with your own hands and approval: technical conditions Selecting a site for installing a gas tank, you need to take into account the following requirements: it is not located closer than 2 meters from the fence of the site and no closer than 5 meters from the building itself.

When the process of drawing up the project is over, it is required to coordinate it with the technical department of the organization engaged in the supply of gas to the region, the next stage is to sign an agreement with the organization to carry out the connection work.

When completing the connection of the house to the highway, the owners of the house, in addition to everything else, must conclude an agreement for the maintenance of the equipment.

Connecting a house to a centralized highway is not a cheap pleasure.

The total cost of gasification includes:

  • collection of documents, which includes payment of various state fees;
  • project preparation, price the development of the project depends on the degree of its complexity and can vary in a wide range
  • the layout of the gas pipeline itself
  • tie-in into the pipeline
  • the price of the boiler, radiators, pipes, etc.

Autonomous gasification will, of course, cost even more.

How to make a project for the gasification of a private house with your own hands and approval: technical conditions When the house is connected to the mains, the owners of the property, of course, must strictly follow the rules for using gas equipment.

The boiler can be turned on for the first time only under the supervision of a specialist from the company with which you have entered into a service contract. All adult residents must undergo safety instructions in Gorgaz.
