Natural gas is considered to be the most cost-effective raw material for heating private homes. Highways supplying "blue fuel" are now laid in many towns and villages. But the connection to them must be made, of course, in compliance with certain safety rules. The owner of the house must obtain permission for this procedure and arrange it accordingly. Below in the article and consider how to connect gas to the house.
Main steps
The gasification process is often a lengthy and, of course, costly procedure. However, the cost of tie-in to the highway of a private house subsequently quickly pays off. Gasification of suburban residential buildings is carried out in several stages:
- house owner chooses type of supply;
- a draft specification is being drawn up in the gas service;
- a pipe stretches from the main highway to the house;
- a gasification project is being drawn up at home;
- installation and construction work is underway;
- checking the fulfillment of all conditions and the actual connection.
Selecting the type of gas supply
Country private houses in most cases have a fairly small area. Therefore, according to the type of gas supply, they usually fall into the first group. Gas consumption in residential buildings with an area of less than 250 m2 most often does not exceed 5 m3 per hour.
For private cottages with an area of more than 250-300 m2 you will have to calculate the maximum hourly gas consumption at the first stage. You can perform this procedure yourself. But it is better to shift this task to the compiler of the technical specifications or the project. In this case, the gas company will need to provide information:
- about the number of gas appliances used;
- heated area.
How to connect gas: TU project
First of all, the owner of the house will need to visit a local supplier of blue fuel and obtain technical conditions for gasification. Indeed, when laying a pipe to a residential building, it is necessary to take into account many nuances - the presence of roads near the house, the features of the terrain, the location of neighboring plots, etc.
Documents in order to obtain technical specifications and subsequently connect gas to the house, you will need the following:
-
passport or power of attorney;
- copy of paper certifying the right to the plot;
- a fragment of a cadastral map indicating the location of the site and the location of the highway.
If the supply pipe partially or completely passes through the site of neighbors, for the development of specifications, among other things, written confirmation of their consent will be required.
So, what documents for connecting to gas at home will need to be prepared - it's clear. The supplier will prepare the specifications within 2 weeks from the date of the request. A reasoned refusal must also be received by the customer within the same period. After the technical specifications are drawn up, the owner signs a connection agreement with the company. In this case, the owner of the house undertakes to pay for all work performed.
Pipe laying: the nuances
For this procedure, gas services take payment depending on the length of the supply line. The cost of installing a meter of pipe is usually 2-5 thousand rubles. If the centralized highway is located at a distance of more than 200 m from the house, it will be problematic for the owner of the site to connect to the gas. Gasket prices in this case increase dramatically.
How to connect gas to the house when the main line is located further than 200 m? In this case, you can pay for laying a pipe to the site, for example, by cooperating with neighbors. If for some reason this option is not suitable, gasification at home will have to be done using an autonomous tank.
How is a project made?
This procedure is the most expensive when connecting gas to the mains. The project can be drawn up both by employees of the local service that issued the specifications, and by representatives of a third-party licensed company. In anycase, to develop this document, the owner of the house will need:
- copy of registration certificate at home;
- topographic plan of the site with the house;
- documents for all devices and equipment used for connection;
- TU.
With a company to draw up a project, in order to connect gas to the house, you will need to conclude an agreement. After that, the company will send a specialist designer to the owner for:
- measuring;
- drawing up a project for distributing gas communications.
It will be necessary to agree with the representative of the company, among other things, the location of the appliances, the method of installing the chimney and the meter.
The cost of drafting a project in private firms is usually quite high. Gas services provide this service at reasonable prices. However, in this case, unfortunately, the terms for receiving the project by the owner of the house are often extended. Sometimes a specialist from the gas service has to wait up to 8-10 months to develop it.
Gas connection rules: equipment installation
The boiler and boiler in the house can be installed by the owner before being connected to the gas main. Equipment of this type for private houses is usually used with low power. Therefore, it is allowed to install it directly in the building.
The room for the boiler, of course, is supposed to be chosen taking into account the established standards. For heating unitit is necessary to allocate a room with a volume of at least 1 m23. Also, the selected room must have at least one window with a window.
The wiring of the heating system, hot water and cold water can also be done independently. For a small private house, this will be a very good solution. However, in a cottage of a large area, the installation of a boiler and a boiler, as well as the installation of heating and water supply lines, should, of course, be entrusted to specialists.
After all the assembly of engineering systems is completed, the boiler is connected to the pipe leading to the house. Of course, this procedure must be performed by a gas service specialist.
Final stage
All the stipulated rules when connecting gas to the house must be observed, of course, without fail. Before supplying the “blue fuel” to the house, specialists must carefully check the system. Following this procedure, the representatives of the gas service produce, among other things:
- inspection of the operation of all installations;
- checking the system for leaks.
If no violations are found, the owner of the house is issued a technical supervision receipt, according to which payment must be made. At the final stage, the installation organization must transfer all technical documentation to the gas service.
Further, within 3 weeks, an employee of this organization will visit the house to connect the gas meter and install seals on it. After that, the owners of the building will be able to use the "blue fuel".
Wohow much will the connection cost?
So we figured out how to connect the gas to the house. But how much will such a procedure cost the owner? Prices for drafting projects, laying pipes, installation work, etc. in different regions of the country can vary greatly. However, on average, the issue price at the main stages of gasification of a private house in Russia will be as follows:
- collect documents for technical specifications - from 8 thousand rubles;
- draw up a project - 3-20 thousand;
- lay pipes from the main line - 2-5 thousand/meter;
- connect gas to the boiler - 10-15 thousand;
- check readiness for operation - up to 2 thousand
In Moscow and the Moscow Region, gasification of private houses usually costs 400-700 thousand rubles for their owners. In the Leningrad region, this procedure costs about 300 thousand rubles. In this region, individuals, among other things, are given compensation for gasification in the amount of 70 thousand
In the European part of Russia, connecting a house to a centralized highway usually costs 70-120 thousand rubles. In Asian regions, this procedure in most cases is quite expensive. This is due to the remoteness from industrial centers supplying gas equipment.
Autonomous gasification
Of course, most often the owners of country houses are connected to the centralized highways. However, sometimes this procedure becomes impossible. For example, in a settlement, a pipe supplying water may not be laid at all."blue fuel", or it is located far from home. In this case, it will be possible to connect the plot to the gas autonomously. That is, using a special storage tank.
Such equipment is called a gas tank and is installed in a pit dug directly on the site. A trench is laid from this pit to the house, along which a pipe is pulled. Of course, the owner of a private residential building, even with this method of connection, needs to obtain a permit for gasification.
TU for Autonomous Systems
So how to properly connect the gas when using the storage tank? In this case, the registration procedure will be almost the same as when inserting into a centralized highway. That is, at the first stage, the owner of the house will need to apply for the preparation of specifications. In this case, the specialist, among other things, will conduct a study of the area and determine the most suitable site for installing a gas tank.
According to regulations, such explosive containers are supposed to be located at a distance of at least:
- 10 m away from residential building;
- 15 m from the water supply;
- 5m away from trees and outbuildings;
- 2m from the fences.
The owner of the site, who decides to connect gas to a private house, should also be aware that the minimum distance from the gas tank to the power line is equal to half the height of the support. Of course, access roads must be provided to such a container forrefueling.
Design Features
At this stage, the specialist also evaluates the features of the site. In this case, research is being carried out, for example:
- degrees of soil corrosivity;
- presence of stray currents, etc.
Based on the information received, the supplier's representative decides whether it is possible to connect gas to the house using a conventional drive, or whether the owners of the site will have to buy a container with additional galvanic protection. The last option of gas tanks is, of course, more expensive.
Also at the design stage, representatives of the gas service determine the necessary characteristics of the evaporator and condenser. In addition, the site owner is given recommendations regarding chemical and lightning protection, as well as grounding methods. Subsequently, the autonomous gasification project will need to be coordinated with the fire inspectorate, environmentalists, electricians, architects, etc.
Gas tanks: safety requirements
Of course, there are, among other things, regulations designed to ensure the safe use of storage tanks in private homes. In any case, the gas tank installed on the site must meet the following requirements:
- all tank fittings must be installed above ground level;
- the distance from the top of the tank to the ground surface should not be less than 60 cm;
- The gas tank must be designed not only for gas, butand vacuum;
- to lean in the pit, the container should rest on its paws;
- a reinforcing collar should be provided on the neck of the gas tank.
At the storage tank, among other things, there must be a plate with the serial number and basic information about the technical characteristics.
Gas in new buildings
Most often, the question of how to connect to gas is, of course, asked by the owners of country houses. However, it also happens that owners of apartments, for example, in newly erected multi-storey buildings, have to deal with the issue of supplying "blue fuel".
How to connect gas in a new building? To do this is quite simple. Owners of real estate located along the riser should simply write an application to the Gorgaz. If this organization refuses, citing, for example, that not all apartments in the entrance are still occupied, you should file a complaint with Rospotrebnadzor. In any case, the response to the application of residents from Gorgaz must be received within 10 days.
Hardware Requirements
How the room for the boiler is chosen, we discussed above in the article. We only add that the height of the ceilings in such a room should not be less than 2.2 m. But, in addition to the heating unit, in country buildings, of course, stoves are also installed during gasification. Such equipment is usually mounted in the kitchen. In this case, if:
- kitchen volume does not exceed 8 m3, it is allowed to install a stove for no more than 2 burners;
- 12 m3 -respectively, for 3 burners;
- 15 m3 - for 4 burners.
Both the boiler and any other gas equipment should be installed in such a way that a free approach is provided to it. In addition, when installing such equipment, it is necessary to observe the following standards:
- the back wall of the stove should be at least 7.5 cm from the wall, and the boiler - 15 cm;
- the distance from the slab to the opposite wall should be at least 1 m.
Many owners of suburban areas, of course, are also interested in how to connect gas. column correctly. Such equipment is hung on a wall pre-sheathed with fire-resistant material. In this case, the flow boiler is supposed to be mounted 3 cm from the building envelope. In this case, the fire-resistant sheet must extend beyond its surfaces by at least 10 cm on all sides.
Each piece of gas equipment must, among other things, be equipped with a shut-off valve. This structural element of the system is supposed to be installed at a height of 1.5 m from the floor. In addition to special pipes, it is allowed to connect appliances during gasification at home using a flexible hose. Of course, only serviceable equipment is supposed to be installed in residential buildings.
Chimney Requirements
Having asked the question of how to connect gas to a private house, the owner must take care, among other things, of installing a pipe that discharges combustion products. Such gasesof course, it should be immediately removed from the house. Requirements for chimneys when installing a boiler in a house are provided as follows:
- when installing the pipe, a moisture collector must be installed;
- all parts of the chimney must be tightly connected;
- The chimney must be located vertically without ledges (the maximum allowable deviation is 30 degrees).
It is forbidden to arrange more than three turns on the gas chimney pipes. Also, you can not stretch such a system through living quarters.
