What if there is a house, but the gas main is not connected to it? The answer is simple - you need an autonomous gasification of a private house, which provides the supply of blue fuel to the gas stove and heating boilers... This is not an easy task, it requires careful design, strict adherence to building codes and special knowledge.
But it is still worth considering this gasification option in more detail, since it has many advantages. We will tell you how the system works, what working units are included in the autonomous complex.
We will describe the specifics of the operation of the gas tank and cylinder gas supply, as well as outline the rules for the design, design and installation of a local gas pipeline.
Gas stove connected to a bottle of liquefied gas is a common phenomenon. By the same principle, it is possible to supply blue fuel to a gas boiler to provide heating and hot water supply to the whole house. You just need a larger container or even several tanks with liquefied gas.
Such systems use an analogue of natural gas as fuel, which consists of a mixture of butane and propane. This mixture is called LPG - liquefied petroleum gas.
To organize an autonomous or alternative gas supply system at home, it is necessary to connect to unified system the following elements:
- LPG storage tank - one or more;
- evaporator (pressure regulator) for gas;
- system controls;
- devices that run on liquefied gas: stove, water heater, boiler, etc.
Special gas appliances for autonomous gas supply country house Not needed. If the boiler or column can operate from the main gas network, then a cylinder or gas holder can be connected to it. This is very convenient if in the future it is planned to bring a centralized gas main to the house, you will not have to change the equipment.
Autonomous gas supply of a private house is usually carried out using a special container - a gas holder, from which liquefied gas is distributed through pipes (+)
The main reason why private home owners are rejecting electric and solid fuel benefits gas units, consists in relatively low operating costs.
Gas, including liquefied gas, is cheaper than electricity or coal. The difference even covers the installation costs autonomous system gas supply.
But if people live in a house or cottage all year round, it is imperative to install an underground tank.
Gas tanks designed for underground installation are more in demand than ground-based models, since they provide a stable storage temperature for liquefied gas
Although it is easier to install a surface gas tank, there are more problems with its operation. Due to the influence of high and unstable temperatures, more stringent safety requirements are imposed on such devices. The cost of surface installations is also generally higher than that of underground counterparts.
If there is a need to use a ground model in winter time, i.e. at low temperatures, you will need to use an evaporator. This is an electrical device that ensures safe heating of a container with gas.
As a result, LPG passes into a gaseous state more quickly and enters the system, providing sufficient pressure.
Underground gas tanks can reach volumes of 50 cubic meters, but a private house usually needs a smaller tank.
Gas tanks designed for underground installation are considered more reliable and safer. However, installing them will take more time, cost and effort.
This is due to large-scale work. Installation above freezing of the soil is not allowed, and in many regions this figure is 1.5 m or even more.
The contents of the tank located inside the ground are almost completely at a temperature of 5-8 ° C. A special evaporator is not needed for this model.
For a specific site and project, the gas tank is selected in accordance with the technical conditions developed for the autonomous gas supply system. Usually, the organization that is entrusted with the implementation of the project itself buys this device, using the discounts that manufacturers provide to such customers.
The gasholder control system is installed on its top cover. The pressure gauge allows you to control the pressure inside the tank, which should not exceed critical limits (+)
An independent search and purchase of a gas tank usually does not give the site owner an opportunity to save money, but increases the risk of purchasing a low-quality or unsuitable device.
On our site there is a series of articles dedicated to the selection and installation of gas tanks.
In addition to gas tanks, cylinders with liquefied gas can also be used for autonomous gas supply. One such capacity is usually not enough, several are combined into a common network.
Features of balloon gas supply
This option is usually used only for small summer cottages with modest volumes of gas consumption. Several are installed in a separate room. It is not recommended to allocate a room in a residential building for these purposes.
It is better to build a separate utility room for storing cylinders, although it is allowed that this room is adjacent to the house.
To connect gas cylinders a set of reducers and pressure gauges is used in a single network. As needed empty cylinders can be replaced with filled ones
A separate entrance should be made here, and not a door leading from the house. The area of the room should exceed the dimensions of the cylinders that will be installed there by eight times.
Inner surface the rooms must be covered with materials that are resistant to fire. Compulsory ventilation is required.
Autonomous gas supply using a set of gas cylinders is preferable to use for a small summer cottage so you don't have to worry about filling them too often (+)
Sometimes it is allowed to store cylinders not in a separate room, but in a large metal box outside the house. It is impossible to heat the storage area of gas cylinders, any heating devices and, of course, the use of open fire are prohibited.
If the room is ready, you must perform the following operations:
- Install cylinders along one of the walls.
- Lay gas pipes from the place of storage of cylinders to devices-consumers of liquefied gas.
- Assemble the system from reducers and pressure gauges for parallel connection of cylinders.
- Connect cylinders and devices to the highway.
- Check the finished system in the presence of employees of the regional gas industry.
- Obtain official permits documents for the operation of a balloon gas system.
The cylinders are installed on special pallets, while they must be given a strictly vertical position. Each container contains about 50 liters of gas, based on this standard, their total amount is calculated. Such a system will cost less than a full-fledged gas supply with a gas holder, but the cylinders will have to be charged quite often.
Design and execution of documentation
A “personal” gas system must be as reliable and safe as a centralized mainline. Carelessness in these matters is unacceptable, since even a small gas leak can cause huge problems and even lead to death.
If the owner of the house does not have special knowledge, then it is necessary to entrust a specialist with a license.
Rather, whole design organizations are engaged in this, having the right to design and carry out work on gasification of residential buildings.
It can be either a private company or a specialized subdivision of the gas service of a district, region, etc. Private traders charge a little more for work than government specialists, but they will also take care of the registration.
When working with regional gas, the owner of the house will have to do the decoration on their own, but you can save a little.
When preparing a project, you will have to not only draw up a couple of statements, but also attach a number of documents to them:
- owner's passport;
- certificate of ownership of the land plot;
- site plan;
- characteristics of the heating system, etc.
First, specialists develop technical conditions for gasification of a building, in which fire safety requirements are taken into account. Then research is carried out on the ground, and is selected taking into account the standards.
The gas tank must be located at a distance:
- not less than 10 m from residential buildings;
- not less than 15 m from sources drinking water and other bodies of water;
- not less than 5 m from trees and outbuildings;
- not less than 2 m from fences.
In addition, it is necessary to take into account the presence of power lines near the installation site of the gas holder. The minimum distance to such structures should be half the height of the support. One more important point- availability of convenient access roads for a car with a liquefied gas tank to refuel the gas tank.
At the design stage, the features of the site are also assessed: the corrosiveness of the soil, the level of stray currents, etc.
Based on these data, a decision will be made about the features of the gas holder, for example, whether it needs additional galvanic protection, which will not affect the price of the device for the better.
Ground models of gas tanks are usually used only in summer period... Higher safety requirements are imposed on such tanks than for underground counterparts.
Thus, the technical conditions for the gasification of the facility are determined. With their help, specialists will draw up a project that includes whole line documents: characteristics of the gas holder, evaporator, condenser, site plan, gas pipeline system plan, recommendations for grounding, chemical protection, lightning protection, etc.
These documents must be coordinated with the fire inspectorate, gas supply services, electricians, architects, environmentalists and other specialists from local departments. The result of the registration will be the receipt of a building permit.
If the site owner wants to reduce the cost of installing an autonomous gas pipeline, he can independently dig a pit for the gas tank. But this must be done in strict accordance with the project. It is better to entrust all other work to specialists so that everything is done in full compliance with safety requirements.
When installing an autonomous gas system, an external pipe laying should be used; only one-piece connections are used to connect individual sections
All gas pipes should only be laid openly, they should not be hidden under a screed, false panels or other decorative elements... You should carefully consider the layout of the piping for liquefied gas.
It is not allowed to conduct such communications in transit through Living spaces, through the kitchen or other utility rooms in which devices that run on liquefied gas have already been installed (or will be installed).
The base for the gasholder must be flat and strong, a sand cushion is arranged for it, on which they put concrete slab suitable sizes
One more categorical prohibition associated with the installation of gas pipes - detachable connections. Of course, the connectors are required at the beginning of the network, i.e. where the network is connected to cylinders or a gas tank. And at the end, when connecting a pipe to a boiler or column, you also need to put a connector.
But throughout the entire length of the autonomous gas pipeline, the connections need to be made only one-piece. The part of the gas pipeline that is laid outside must be taken care of additionally.
The entire external network should be carefully insulated using special materials that are resistant to fire. In addition, it is necessary to ensure the drainage of condensate, this will reduce the likelihood of pipe corrosion.
To reduce the cost of installing an autonomous gas pipeline, you can independently dig a pit for an underground gas tank, but you must follow the design documentation
The gas boiler must be installed in a separate room - it will be needed. Its area must be at least 15 cubic meters. m. In the room it is necessary to make a window, the opening area of which is at least half a cubic meter.
Such a hole in outside wall will create an outlet for a blast wave in the event of an accident. If the gas explodes in a room with blank walls, the entire building could be seriously damaged.
At the entrance to the boiler room, a door should be installed that opens outward. Another point that cannot be neglected is the ventilation of the boiler room. Inflow fresh air must be constant in order to ensure combustion of the gas.
A sufficiently good air exchange must be ensured so that the gas does not concentrate in a room with an open fire in the event of an accidental leak.
The gas boiler should be installed in a separate room with a window and a door that opens outward. Finish with fire-resistant materials
Ventilation will also prevent flue gas poisoning if chimney problems arise. If it is not possible to allocate a separate room for the boiler, it is allowed to install some models in the basement or on the basement.
But in this case, it is imperative to install a system in the room with the boiler to control the level of hazardous gases in the air.
Installation work on autonomous gasification with a gas holder usually takes two or three days. But after their completion, a number of documents should be drawn up and some approvals should be carried out. The tightness test of the finished system should be carried out under the supervision of specialists from the regional gas organization and Rostekhnadzor.
Before backfilling an underground gas tank with sand, it is necessary to wait about two to three weeks after its installation.
After checking, the gas tank is covered with sand, after which you need to wait about three weeks before filling the tank with liquefied gas for the first time. The completion of work must be formalized with an official act of acceptance and transfer. At the same time, a service agreement is usually concluded.
Sometimes it is more convenient to invite different contractors for the installation of external and internal gas pipelines. In this case, experts recommend delimiting the responsibility between the performers and formalizing this moment in a separate act. It would also not hurt to take care of civil liability insurance.

The procedure for working with autonomous gasification of a private house is described here:
Setting up your own gas supply system at the site is a troublesome and costly task. However, it is very convenient to use your own gas, you can refuel only a couple of times a year.
In addition, such a system is cheaper than endless electricity bills, and solid or liquid fuels lose economically to a gas boiler.

Gas connection to a private house is a guarantee of comfort and coziness. Without quality heating private house heating in winter is quite problematic, and a gas boiler is rightfully considered one of the most reliable and economical solutions. Even if gasification of a house will cost a tidy sum, it is not worth saving on this, since in most cases there is a benefit compared to alternative sources heat is evident even with superficial calculations. Besides, gas is one of the most convenient energy sources. On gas stove it is very convenient to prepare food, and the boiler will warm up the house quickly and efficiently. When and how to properly supply gas to a private house, the price of work will be disclosed in our today's article.
A gas stove and boiler are some of the most efficient devices for cooking and heating your home.
What can be the gas supply
It is possible to provide a private house with "blue fuel" in two ways.
- Gas connection. If a gas pipeline is laid 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 conduct a connection. The easiest way to find out where to go is to ask neighbors who have already been supplied with gas. You can also walk along the pipe and find a distribution station - usually it has phone numbers written on it. service company... As a last resort, you can call the 104 service, but it is better to ask first desired number from neighbors;
- But there are places where it is impossible to connect to the gas main. These are mainly distant villages and dachas located away from the central villages (for example, on the shore of a reservoir). But 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 all year round, it is only worth replenishing the "blue fuel" stocks once or twice a year. Many specialized companies have already opened that will help to correctly calculate the volume of the gas tank, make permits, and install it in the right place.
Gasification scheme of a private house using a gas tank
Gasification of a private or country house - where to start
The first thing to start with the gas supply of a private house is the 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 holding installation works... After that, the specialists will develop the project, it will be approved by the permitting authority, and the employees of the gas industry or a company that has permission for such work will begin the connection process. The cost of connecting gas to a private house before the development of the project can only be given to you approximately, since the final price of materials and services consists of many components.
If a gas main is already passing near the house, then you will have to pay only for the tie-in into the pipe - otherwise, the cost of the project most often includes work on drawing the line down 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 the start of installation work, and some can be drawn up during the process, therefore, if it is not possible to make all the documentation at once, then priorities must be determined in advance.
Here list of documents that must be submitted to the appropriate authority in order to be allowed to supply gas to a private house:
- Statement in writing... The preparatory work will begin with him (analysis of the area, buildings, etc.);
- Provide copies of documents that prove the identity of the customer (with copies you must submit the originals);
- Provide copies of documents that confirm the right to own the house (also present the originals for comparison with copies);
- If the gas pipeline will pass through the neighbors' section, 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 survey.
All the necessary documents can be collected and provided independently, or entrusted to other persons by issuing an appropriate power of attorney for them.

How to make a gas supply plan for a house (gasification project)
A gas supply project for a private house is a necessary component to start all work. Gas-consuming installations are potential sources of danger and safety regulations are required.
To draw up the correct gas supply plan for a house, specialists need to thoroughly know all the points normative documents and strictly comply with them. The technical department of gas facilities always checks the compliance of the plan with the requirements of regulatory documents and, if necessary, returns them for revision.
The requirements that gas facilities place on projects may differ depending on the landscape of the area, the method of installation, and the installation conditions. It may take several weeks or even months to thoroughly check the plan.
Projects must be strictly individual, plans that have been developed for other houses are prohibited by law, and criminal liability is provided for this.
The project must indicate the layout of the house and location gas equipment
The stages of connecting gas to a private house in each case will differ, since they depend on the topography of the site and individual features of the gasification plan.
How is the construction of a gas pipeline going (connecting a gas line to the house)
With an approved project, you must contact a company that is engaged in such work (necessarily with a state license). If the estimate compiled by the company suits both parties, then an agreement is concluded on the implementation of the corresponding work.
In the contract, it is imperative to indicate that the final settlement will be made only after the completion of all work, and their acceptance by an official commission.
Upon completion of the installation work, executive 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 a contract for the installation of equipment that will be connected (boiler, stove, etc.).
Commissioning works must be carried out exclusively by specialist gas workers.
The end of gasification (connecting gas to the house) is also an important stage.
At the final stage of gasification of the house, it remains to be instructed on safe use 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 project documentation (or an approved copy) for safekeeping in the archive, in case redevelopment is required later or any clarifications are required.

What has changed in the rules for gasification of a private house
Until 2016, it was quite difficult to even roughly predict how much it would cost to connect gas to a private house, since there was no legislative regulation and control. This led to the fact that monopolists could single-handedly set the timing of gasification and its cost. But, with the adoption of new laws, the maximum terms for gasification were limited to one and a half years.
The specific amount in which all work will be carried out, without finished project it is difficult to name even now, but at least a price bracket of 20-50 thousand rubles has been fixed for bringing the gas pipeline to the site, plus installation work inside it.
The cost and terms of approval and implementation of a gasification project for a private house are now regulated by law. This means that the party ordering the services can now take a more active part in the control of the work and demand their timely completion.

What other questions arise about the cost of connection, described in the video:
Conclusion
Although gasification of a private house is a long, tedious, and expensive process, its importance cannot be overemphasized. Everyone who has the opportunity to gasify the home is doing it first, especially since with the adoption of new laws, the population has the opportunity to predict the timing of work.
This article discusses the main issues of gasification of a small country house: how to lay a gas pipeline, on what principle to choose gas equipment and who to entrust its installation, how to comprehensively organize gasification work and what "pitfalls" lie in wait for the customer along the way.
Currently, the issue of gasification of a country house has acquired particular relevance. The main reason for this is both the rapidly developing construction of the private sector in the suburban area, and the laying of gas mains to the already equipped suburban areas and cottage townships. In the first case, the plan for gasification of housing and auxiliary buildings, as a rule, is included in the general construction plan. In the second, it requires the development of a special project, taking into account the individual landscape and architectural features of the existing structures. Both in the first and in the second case, the development of the project, the selection of the necessary equipment, its installation and connection is carried out by qualified specialists.
Gas boiler and radiators or convectors
Designing the system gas heating of a country house, the following factors must be taken into account:
- total area of heated premises;
- ceiling height;
- the degree of thermal insulation of the walls and roof;
- internal layout of the house;
- wall thickness;
- outdoor and interior decoration, decor of walls and windows.
General view of the gas pipeline system on the wall of the building when installing gas convectors
You should also consider how often power outages occur, and if country house- the need for heating it in winter.
On the question of choosing a gas boiler or convector heating, the opinions of specialists boil down to the following: if it is enough large area(over 100 sq. m.) of a country house and permanent residence in it, it is necessary to install a gas boiler and radiators. Comparatively oversized two- and three-room country buildings with a seasonal visit, it is cost-effective and efficient to heat with gas convectors.
Hole for the gas pipe when connecting the convector
In the first case, develop a gasification project and select necessary equipment only an experienced specialist can.
In the second, you can independently decide on the choice of heating elements and their location, having agreed with the future performers of installation work on the project for installing gas equipment.
This kind heater received well-deserved recognition for a number of reasons, of which the most important are its energy independence, the absence of a freezing element, the efficiency of heating the room and ease of operation. When choosing a gas convector, you must be guided by the following parameters:
Fuel used
Most of the convectors offered for sale today are initially configured to operate on either natural gas (methane) or liquefied gas (propane). It is possible to transfer the device from the consumption of main fuel to bottled gas or vice versa, but this will require an additional set of nozzles, which must be installed with high degree reliability can only be experienced.
power, kWt
The required power of a gas convector recommended by manufacturers is calculated as follows - 1 kW of power per 10 sq. m. area. Thus, to heat a room with an area of 20 sq. m. a convector with a capacity of 2 kW is required. However, it is necessary to take into account such characteristics of the building as the height of the ceilings, the thickness and level of thermal insulation of the walls and roof, the number of windows. With a room height above 3 m, a large number of windows or insufficient thermal insulation of the walls, an accurate calculation of the required power of a gas convector can only be done by a heating engineer.
Heat exchanger material
Most represented at domestic market gas convectors are equipped with steel or cast iron heat exchangers. According to experts, with all other things being equal, cast iron burners should be preferred. The reason for this is the slight thermal expansion and the property of this material to accumulate heat, due to which a high durability and high thermal efficiency are achieved.
Flue pipe length
When buying a gas convector, you need to pay special attention to the length of the chimney pipe or, as it is also called, the flue. Some manufacturers produce models with short (35 cm and less) pipes, designed for "cardboard" country houses... Of course, there is always the opportunity to "build up" such a pipe in a tin workshop, but, nevertheless, it is better to initially decide on its desired dimensions.
Installation of the flue pipe - its length must correspond to the thickness of the wall
Fan presence
The main function of the fan built into the convector is to quickly generate heat in the room due to the accelerated air circulation. The feasibility of installing a model equipped with a fan is determined in individually and depends, first of all, on the regularity of using the convector during the heating season. When summer cottage option when it is often necessary to quickly heat up cold house, the functionality of the fan is obvious. At permanent residence and regular use of the convector, additional noise effects created by the fan are completely unnecessary.
The question of the method of laying gas pipes is solved in a complex way and depends on the following factors:
- remoteness of the building from the central gas main;
- features of the landscape of the adjacent territory - green spaces, reservoirs, asphalt paths, high-voltage power lines, residential buildings and public buildings;
- corrosive soil characteristics;
- the geometry of the building itself - the height of the arches, doorways, configuration of angles, symmetry or asymmetry of an integral architectural complex;
- own wishes of the owner of the territory and his financial capabilities.
There are three ways to connect to the central gas main.
Underground gas pipeline
The most expensive, aesthetically pleasing and reliable solution... However, when choosing this method, which will cost more than one and a half times more than its above-ground analogue, one should take into account the laboriousness and significant cost of repairs in the event of an accident. In addition, high rates of soil corrosiveness can significantly reduce the service life and reliability of an underground gas pipeline.
In this case, the pipes are fixed on separate supports made of non-combustible materials or are attached to the walls of buildings with special brackets. In this case, the distance between the supports should not exceed 2 m, the minimum distance to the ground surface should be less than 35 cm and functional purpose buildings and their material exterior cladding comply with the established standards.
Installation of an aboveground gas pipeline - fixing the pipe on special supports
Special retaining ring with rubber gasket
Methods for attaching the pipe to the wall of the building
In the photo, the down tube is not fixed correctly. Metal-to-metal contact is unacceptable. It is necessary to use rubber gaskets and retaining rings as in Photo 4.
Often, optimal solution gasification is a combined line laying. Carriageway or high voltage lines power transmission lines must be bypassed underground, while it is possible to save green spaces and not damage the fertile soil layer by laying pipes through the air.
The final decision in favor of this or that method of laying the gas main should be made only after consultation with a qualified specialist.
How to organize the gasification process
There are two ways to solve this issue - step-by-step and complex.
In the first case, it is necessary to independently study the legal aspects, regulatory requirements and the traffic plan for licensing and design organizations, collect all the mandatory documentation, conclude an agreement with the construction and installation team and the service that is engaged in tapping into the central gas pipeline, agree on the timing of commissioning with organization of service. Not everyone is able to find the time and opportunities for this kind of movement, which, moreover, will not in any way reduce the overall financial costs.
It is possible to solve the gasification issue much faster and more efficiently by entrusting one contractor to carry out complex organizational and technical work on a turnkey basis. From an economic point of view, this approach justifies itself both in the process of project implementation and in the course of the subsequent operation of gas equipment. This is due to a number of factors, which are discussed below.
The advantages of integrated gasification:
- the contractor's interest in carrying out all gasification works as soon as possible;
- interest of the contractor in drawing up an engineering literate and appropriate to all regulatory requirements a gas project, which he himself will implement;
- established contacts of the contractor with trading construction companies, which allows him to purchase gas equipment at lower prices;
- long-term cooperation of the contractor with licensing and controlling structures makes it possible to timely and consistently carry out all gasification works.
Turnkey gasification pitfalls
When entrusting the gasification of a house on a turnkey basis to a specific organization, it is necessary to familiarize yourself with the list of documents that should be in the hands of its owner upon completion of all work. It is not uncommon for the contractor to “forget” to hand over the documents to the customer, without which further warranty service of gas equipment is impossible. In addition, the close acquaintance of the contractor with the representatives of the Gaza Mountains, who are part of the commission for accepting installation work, allows the latter to turn a blind eye to some shortcomings and regulatory deviations, which may subsequently result in additional costs for the customer. A common situation is when, using the incompetence of the customer, the contractor convinces him of the need to install unnecessary or insufficiently optimal equipment in a particular case, thereby providing a mutually beneficial service to his trading partners. To protect yourself from unfair actions on the part of third parties, it is necessary to take special responsibility towards the choice of the contractor for the entire range of works.
Who to entrust complex work on gasification of a residential building
Construction and installation organizations that offer integrated gasification services must have licenses not only for technical, but also design work.
Before concluding an agreement, it is advisable to look at the facility already gasified by this organization, to talk with its owners.
Clearly stipulate the timing of the work and carefully study the sketch of the project - "growing" the heating system will cost much more than the planned installation.
Consider the presented estimate of gasification works. At the same time, conversations about "unforeseen expenses" often do not testify in favor of the contractor.
Make sure the plan includes small cosmetic work- painting of pipes, sealing of holes, removal of construction waste.
Having decided on the choice of a construction and installation organization, conclude an appropriate agreement providing for penalties in case of violation of the conditions for its implementation.
Rational organization of the gasification process of a country house and a competent approach to the choice of equipment that is optimal in each specific case, allow you to implement a project of any complexity as quickly and economically as possible.
Irina Nechaeva, specially for RMNT.ru
Private houses that are not connected to a common centralized heating system must be heated with one of the alternative species heat supply. One of them is heating gas boilers... However, in order for the owner of the house to be able to use this service, it is necessary to do work to connect the housing object to the general network of users. natural gas... But, at the same time, it is necessary to find out that gasification of private houses is carried out in compliance with special rules and procedures.
Gasification of a residential building: rules for connecting to the highway
The main advantage of supplying heat to a house using a gas boiler is its ease of use and low cost. natural resource... Even provided that the gas boiler itself will cost more than an electric one, or other alternative, but since the price of gas is not particularly high, homeowners will be able to significantly save money on heating in the future.
However, it must be borne in mind that gasification of private houses is a responsible and serious process. It is produced in accordance with the standards established by law. In order for the gas economy to give the go-ahead to connect your heating unit to a common line, you must install it in accordance with the requirements and ensure its safe use.
No gas appliance can be connected independently. It is imperative to obtain a permit from the gas industry. In addition, there are installation rules for each gas appliance, which must be strictly observed.
Here is some of them:
- Permission to connect to the central highway or installation of a gas tank can be issued only if the site is in the personal ownership of the owner of the house;
- In the house itself there is a room in which, according to the standards, a boiler can be installed;
- The gas boiler, according to the position, is installed only in non-residential rooms;
- Practice shows that usually boilers are located in the kitchen, or in a room specially equipped for this;
- The boiler room can be located on any floor, including the basement;
- The volume of the boiler room must be at least 15 and the height of the ceilings must be at least 2.5 m.
- Inside the room there must be an opening window or other ventilation.
These standards are approved for boilers with a capacity of up to 60 kW. Usually, this power is sufficient to heat a private house. More powerful boilers require different installation standards. An estimate is usually developed for them.
Documents for gasification of a private house
Gas supply to a private house is a painstaking and responsible process. In addition to the fact that it is necessary to correctly install the devices, it is also necessary to draw up the necessary documents in accordance with the norms.
In order to carry out gasification frequent home, you need to provide:
- A copy of the technical passport for the building;
- Provo ownership of the premises;
- Supporting documents for the purchased gas equipment;
- Gas supply project;
- Copies of the home owner's passport.
First of all, you will need to visit the local architectural and planning office, where the permission is issued to equip the facility in writing. After that, you will be directed to the fire department, which will instruct you and inspect the chimney. The gas service will ask you to indicate the approximate volume of blue fuel that you plan to use and write an application for connection. After considering the appeal, you will be given the appropriate documents and will be connected to the highway. To regulate the relationship between the gas supplying organization and you, you will need to conclude an agreement, according to which you are obliged to pay for gas services in a timely manner.
House gasification project
The cost of heating with gas differs significantly from electric, and, naturally, such "heat" is not so difficult and dirty as wood-burning. However, in order to connect this comfortable heating, you will have to work hard, give your all financially and withstand more than one line in various institutions.
If you are only at the stage of choosing a site for building a house in which gas appliances will be equipped, then it is advisable to give preference to an area where communications have already been carried out. If the main pipe is nearby, this will greatly facilitate the situation.
Gasification designplug-in house building is done in several stages:
- To measure the parameters, a designer leaves for the site, who will draw up a gasification project for a private house;
- At the initial stage, the arrangement of gas equipment in the room is coordinated with him, and the mari and the types of devices that you will purchase are determined;
- Instrument data is entered into the project.
In rooms with an area of 200 m2 or more on the basement or ground floor, a separate room is allocated, called the boiler room. In it, you need to make two doors, one from the house and from the street. This will facilitate maintenance of the premises. If the room that you plan to heat is small, then a gas boiler with a capacity of up to 30 kW will be enough for you. It is allowed to be installed in the kitchen.
Gas start: which boiler to choose
In order to choose the right boiler, which will heat your premises in the future, it is necessary to correctly calculate the power gas apparatus... This is done according to the following formula: the heated area of the room must be divided by 10. Then, to the result obtained, add 20%, which are necessary to replenish the heat losses. The resulting figure will indicate what boiler power you need to choose.
Having gas appliances in the house initially, do it competently and responsibly. Keep in mind that without the permission of the gas service and making changes to the gasification project, you cannot move anything to another place.
Underwater gas pipe to the house must enter the wall of the boiler room or kitchen, where the metering device for the consumed gas volumes will be located. Its diameter is determined by Gorgaz.
What models of boilers exist:
- Outdoor;
- Wall-mounted;
- Wall mounted.
In addition, the devices can be with or without pumps. Please note that those units that require an electrical connection will not operate during periods of power outages in your area. Another prerequisite for the installation of gas equipment is the presence of a chimney. Combustion products must come out through it.
