Autonomous gas supply - how expensive will such independence cost? Active gasification

Autonomous gasification of a turnkey private house. Full review

Wanting to provide gas to their home, each owner must ask himself the main question. Is there an opportunity to power the building from the main gas networks in the area? Not every residential area has gas pipelines, to which you can connect with your subscriber input.

Even if a large-sized pipe runs through the site, which, according to the homeowner, can be an excellent source of gas supply, you should not flatter yourself. It may well be that this gas pipeline is not intended to power private buildings, but supplies high-pressure gas to production.

It is strictly forbidden to arbitrarily connect to such networks, and no one will give permission to connect. What to do?

The concept of autonomous gasification

Autonomous gas supply scheme If, ​​after contacting the gas service, it turned out that it was really impossible to supply natural gas to the site, there is only one solution to the problem. Provide gas supply to the house from an individual source.

For all engineering communications there is the concept of autonomous supply. In water supply networks, a private well serves as an autonomous source, in heating - a mini-boiler room, in ventilation - an individual supply and exhaust unit.

For autonomous gasification at home, equipment is used for the storage and use of liquefied hydrocarbon gas (LHG),

Helpful information: a simple complex of facilities allows for gas supply to all household appliances houses without connection to gas pipeline networks, receiving specifications and other permits.

Necessary equipment

The main element of the individual gas supply system is considered to be a gas tank - a container for storing fuel.

Manifold constructive solutions allows you to install it on the site above ground or underground, in a horizontal or vertical modification, of course, with the function of regular refueling. The volume of injected gas is calculated based on the hourly need of the house.

As the main consumer devices, the following are considered:

• hot water gas boiler;
• geyser;
• kitchen gas stove;
• hearth or fireplace.

Each of these devices must have a technical passport, which must indicate the hourly and second gas flow. Knowing the characteristics of the device, the number of hours of operation per day and the properties of the gas, the hourly, daily and annual fuel demand is calculated.

Based on this value, taking into account a small margin, the minimum required volume of the gas tank is prescribed. For small private houses, it does not exceed 3000 liters.

Keep in mind: it is better to entrust the choice of equipment installation location and its characteristics to designers.

In addition to the fuel storage, it is necessary to provide for the installation of a number of means to control the gas supply to the house. This includes:

1. Shut-off valve required to shut off the gas supply from the gas tank.
2. Pressure gauges for monitoring the pressure inside the gas tank and at the outlet from it.
3. Gas reducer designed to reduce gas pressure to the minimum permitted values. Home appliances cannot operate on medium pressure gas, and it is in this state that it is stored in a gas tank.
4. gas pipeline low pressure supplying gas to the house.
5. Gas meter, which is set to fix the gas flow.
6. Automatic protection systems necessary for monitoring and warning of a possible gas leak.
7. Systems fire protection. Here we are talking about a thermal shut-off valve, which, when a certain temperature is reached in the room, automatically shuts off the gas flow through the gas pipeline.
8. Home gas appliances that directly consume gas.

What does turnkey gasification include?

Companies that arrange a gas supply system of extreme readiness take responsibility for the implementation of a whole range of services.

This includes:

1. Departure to the place and measurement of all dimensions of the site. This work is necessary to draw up a site plan, place all existing buildings on it, determine the degree of improvement and outline the location of the future gas tank and gas pipeline.
2. Building a plan of the house with the application of all gas-consuming devices on it. Collection of passport and technical characteristics of equipment.
3. System design taking into account the requirements of modern regulatory documentation. This includes the selection and proper placement of a gas tank, tracing a low-pressure gas pipeline around the site and the house, selection of the necessary shut-off, control valves and automation.
4. Purchase of certified equipment and materials in specialized stores and its delivery to the construction site.
5. Installation of the designed system. If it is impossible to carry out the construction strictly in accordance with the project, the designers are called to correct the decisions made.
6. Gas pipeline testing, troubleshooting.
7. Providing a guarantee for the work performed.

Gas consumption

You need to understand that there are no universal characteristics of gas consumption that will suit every home. The amount of fuel used in the house is influenced by many things that are only found out at the survey stage.

Two outwardly similar cottages can have completely different gas costs.

Gas consumption at home depends on:

• thermal properties of enclosing structures. The presence of a good insulating layer significantly reduces heating costs;
• climatic region of construction;
• the total area of ​​the building;
• the method of heating the house, the presence of warm floors and a fireplace in it;
• the number of gas-consuming devices: boiler, water heater, gas stoves;
• number of parsing points hot water;
• degree of automation of gas supply and heating systems, allowing to turn off the fuel supply in any emergency situations;
• the individual level of comfort of the inhabitants of the house, which is expressed in the degree of heating of the premises in the cold season, the frequency of cooking and the use of hot water.

The annual gas consumption will be 2700 liters, if we take as a basis a house with the following characteristics:

• one-story, with an area of ​​100m2, built in middle lane Russia;
• the house has one household boiler and 1 stove, no heated floor;
• three mixers;
• there is a system for automating gas shutdown in case of fire or accident.

Operating experience

Most owners of private houses who have organized autonomous gas supply on their plots are satisfied.

First of all, people are attracted by the quick arrangement of the gas supply system, which will not entail bureaucratic red tape.

Secondly, independence from the gas supply organization that establishes its own rules for the use of gas. In addition, the installation of gas supply on liquefied petroleum gas is much cheaper than the preparation of a natural gas consumption system.

If the homeowner does not have the opportunity to gasify the house from a common gas main, you can always equip an independent gas consumption system. As a result, such a set of devices will be quickly installed on an empty site, which can be freely used, regardless of the permits of the gas service.

Ways of gasification of a country house

Residents of rural areas and suburban cottage settlements want to enjoy the same benefits of civilization that are available in the city: electricity, water supply, Internet, television. One of the most difficult engineering tasks is the gas supply of a private house. Is it possible to solve this problem and what are the ways?

Gas supply in a private house

On the outskirts of large cities, solving the issue of gas supply is quite simple, since there are centralized highways to which you can connect. This service is not cheap, but if you buy a finished cottage within the city, it is usually connected to all communications.

If you live in one of the districts of the Moscow region, gas supply must be ordered from public or private companies. You will be offered two options:

• connection to the highway;
• autonomous gas supply.

Connection to the highway is possible only if it passes through your village. Pulling a pipe from a long distance is a costly pleasure. But if the entire village draws up an application and submits it to the relevant authorities, then the cost will be equally divided among all households that have expressed a desire to connect to gas.

There are several options for autonomous gasification:

• installation of underground gas holders;
• installation gas cylinders;
• installation of a mobile gas tank on a trailer.

The last two methods will be ideal if your house is not the largest, and you use gas only for cooking. If you want to install a double-circuit gas boiler that will work for heating and water heating, then even a few cylinders are unlikely to be enough for you for a long period of time.

Installation of a gas tank is a complex task, since a tank with a volume of more than two thousand liters will be placed in a pre-prepared pit and filled up. Pipes are laid from it to the auxiliary rooms of the boiler room. This volume of gas at economical consumption will last for six months. It is also important to choose a boiler with a high coefficient useful action.

The advantages are obvious: hot water and heating, the ability to take a hot bath or shower, you do not depend on the central gas system. But the disadvantages also make themselves felt: high price installation work, it is necessary to regularly fill the container with gas and conduct it Maintenance.

Autonomous gasification of a private house: gas consumption, recommendations, tips

Warm batteries, a hot bath and cooking on gas are a common thing for city dwellers, but for owners of suburban areas and summer cottages, all this is often not available, so autonomous gasification of a private house becomes necessary.

Thanks to an autonomous gas supply system, owners of summer cottages and suburban areas will be able to heat their homes at any time of the year, while spending much less money than when heating with electricity and other methods.

Features of autonomous gasification

When arranging an autonomous system, gas is supplied not from the central pipeline, but from its own storage.

An example of the simplest such gas system is known to everyone - these are propane-butane cylinders that are connected to the tiles in the country.

However, more than for cooking such cylinders will not be enough for anything. For heating the whole house, other containers are used - gas holders.

Autonomous gasification - very simple system operating independently of the central gas supply on liquefied gas.

Installing such a system has many advantages:

• First of all, a propane-butane mixture is a fairly economical type of fuel that is easy to deliver to its destination;
• Propane-butane is environmentally friendly and safe for environment;
• efficiency of autonomous gas heating about 97%;
• Combustion products with such heating are absent, as well as the smells of gas and burning;
• Autonomous gasification is installed very quickly, usually it takes less than a week to complete all the work;
• Autonomous gasification allows rational use household plot country house or cottages.

The system is installed as follows: a special underground storage facility is installed on the site for dispensing gas, which is called a gas tank.

Pipes are laid from this tank, which supply gas to consumption points. Depending on what the consumption will be, the storage is filled with liquefied gas 1 - 3 times a year.

It is delivered to its destination by special gas carriers.

When the gas in the liquid state enters the tank, it changes from the liquid state to gas due to the heat of the earth, and the vapor phase enters the pipe under low pressure to the points of consumption.

Many are interested in what fuel consumption with such a heating system country building.

Studying the reviews of those who already use such a system, we can conclude that a lot depends on the size of your suburban home and other nuances, but you can reduce consumption consumption through control and regulation functions.

propane butane

Autonomous gasification is carried out by methane, which is unusual for us, but by liquefied propane-butane, which is usually also used for refueling vehicles.

Conventional natural gas, which we receive through a centralized pipeline, is very difficult to store, unlike a propane-butane mixture.

It is possible to liquefy natural gas at -160°C and at a pressure of 200 bar, and it is very difficult to obtain such conditions.

Buying natural gas in a liquefied state is also quite problematic, while propane-butane is sold at any gas station.

Propane-butane has many advantages, one of which is its efficiency.

During the combustion of this mixture, more energy is released than during the combustion of main gas, so the consumption of such fuel is much less.

However, this fuel also has disadvantages - when the temperature in the storage drops, condensate forms, which prevents the gas from flowing normally through the pipeline, so storage tanks are installed below the freezing level so that the temperature in the tank is always positive.

Many fear that this system is not a safe way of heating and choose other options.

However, you should know that the design is completely safe, thanks to the low pressure in the system, grounding and special sensors that close the necessary valves in the event of a leak.

Autonomous gasification device

The device of such a system can be studied according to this scheme.

Its basis is an underground tank - a gas tank equipped with:

• safety valve;
• liquid phase selection valve;
• steam extraction valve:
• level gauge;
• filling valve;
• system pressure regulator.

In our climate zone, horizontal storages are usually used, which are produced by the Chemet plant.

Such gas holders can be installed below the freezing level, and a large evaporation area allows you to easily switch from liquid to steam without additional equipment.

High branch pipes and a mouth do not allow flooding of a regulator of pressure during thawing of waters. Such tanks will work properly for many years even in the most frosty winters.

The volume of the tank usually averages from 4 to 9 thousand liters, depending on the size of the housing, such a volume of gas can be enough to heat the home for three to four months.

At the top of the tank neck there is a reinforcement compartment. Inside it are shut-off valves that control the flow of gas.

In addition, there may also be a hatch, which is used in case a specialist check inside the gas tank is necessary.

The next element of the system is a reinforced concrete base, on which the gas tank is installed and fixed.

They do this so that the empty tank does not float during the increase in level. ground water.

For the base, a solid road reinforced concrete slab is taken, to which a container is attached with stainless pins through special holes in the supports.

Not far from the tank, an anode-cathode protection system is installed - magnesium alloy anodes, which are connected to the tank.

During the operation of the system, magnesium is oxidized and restores the iron from which the container is made. Thus, the service life of the tank is extended by several decades.

Underground gas pipeline device

To transport gas from the storage to the premises, an underground pipeline is used, which is placed below the freezing depth.

Autonomous gasification of a private house involves the use of special low-pressure PVC pipes with high strength.

In order for the system to be stable and not stop even under the most low temperatures air, it must contain a condensate trap - a device that serves to accumulate and evaporate liquid butane, which appears on vertical surfaces pipeline in winter and may cause a fuel cut.

The condensate collector is a closed container with inlet and outlet pipes, as well as a drain pipe, which is led out into the gas tank casing.

Since, according to safety standards, the introduction of gas into the house underground is prohibited, the underground pipeline ends with a basement input.

This is an element of a steel pipe, a crane and a special device that takes into account shrinkage and displacement of the structure and acquires desired shape while maintaining tight connections.

The joints of polyethylene and steel pipes are one-piece and placed in a special case.

If you wish, you can also install a valve at the entrance to the room, which will be used in the event of a leak in the room.

The device of the internal gas pipeline

An internal pipeline is laid in the room, which delivers gas to consumption points in the house.

It includes:

• cranes;
• gas alarm;
• stop valve;
• manometer;
• pressure stabilizers;
• consumption meter.

The pipeline to the room is made of steel pipes in such a way that there are a minimum number of connections on it.

A thermal shut-off valve is a device that shuts off an internal gas pipeline in the event of a fire. This valve is activated when it reaches 100°C.

The gas alarm is an element that monitors the state of the air in the house.

It continuously checks and signals in the event of the appearance of gas vapors in the air with a concentration of at least 10%, and also activates a shut-off valve, which is placed on the internal pipeline.

Using two or more gas tanks

Often you can find the use of several tanks at once, which are combined by a vapor and liquid phase.

In this way, it is possible to increase the volume of storage of liquefied fuel, as well as the area of ​​its evaporation. In this case, you can fill the tanks in turn or at the same time.

Often one gas tank is used immediately for 2 - 3 houses and even more. If the houses belong to different people, then the owners of the houses must agree among themselves on the location of the reservoir.

In addition, metering stations should be installed near each house so that there are no disputes over the amount of gas used.

If you decide to make a common system, then you should take into account what kind of relationship you have with your neighbors, since the operation of the system can hardly be called autonomous.

Therefore, it is better to still install your own system, and not share it with someone.

Remote system management

Since this gas system is usually installed in country houses and cottages that are far from highways, and, consequently, from the settlement, it can be equipped with a universal GPS / GPRS module.

This element will allow you to control the gasification system from almost anywhere in the world using the Internet or a mobile phone.

Thanks to this module, you can turn the system on and off while away from home, which will help you reduce gas consumption, as well as turn on the system a few hours before you arrive at your Vacation home.

Besides, autonomous system gas supply can also be supplemented with a remote level gauge or a telemetric fuel level control system.

The remote level gauge allows you to know the level of gas in the tank right from home. Special device shows the percentage of fuel level and signals if it falls below 10%.

The telemetry system allows you to control the fuel level in the tank using the Internet and a mobile phone.

Last years autonomous gasification of summer cottages is becoming more common and has positive reviews.

Considering also its safety and efficiency, you can safely install it to heat your suburban home.

Any developer thinks about choosing an energy carrier for heating a house. In terms of convenience and cost the best option today's natural gas is methane.

But what if there are no natural gas distribution networks nearby?

Back in the 1970s and 1980s, group storage units for liquefied gas were widely used for gasification in Ukraine, which were eventually replaced by centralized gasification systems. In Western Europe and the USA, gasification with liquefied natural gas (LPG) continues to be relevant. For example, in the same Poland today there are over 100 thousand autonomous gasification systems.

New cottage developments today often grow at a decent distance from gas communications, and even if communications are not far away, gas does not come to the villages immediately anyway. Most often, it remains to wait for years to supply gas, after which it turns out that the initial costs of connecting to the central gas supply significantly exceed the amount of costs that you originally expected. You are even ready to consider purchasing an electric boiler.

No need to hurry! First, most likely, you will not be able to achieve the allocation of appropriate electrical power. Secondly, in case of an emergency power outage, you will need a powerful diesel generator that can ensure the operation of an electric boiler for a certain period.

Any energy carrier is used to generate thermal energy. Therefore, to determine the economic feasibility of using liquefied gas as a source of heat, we compare the cost of 1 kW of energy obtained from it with other energy carriers. The total heating costs of a private house depend on the outside temperature and the heat losses of the house.

Table 1. Economic efficiency of using the most popular types of fuel for heating a private house.

Choosing a boiler and determining its heat output

A reliable calculation of power can only be performed by a specialist, however, an approximate calculation is easy to do on your own.

It is generally accepted that for a well-insulated house with a ceiling height of up to 3 m, for heating every 10 sq. meters of its area will require an average of 1 kW of boiler power. Those. for a house with an area of ​​200 sq. m it will be 20 kW. The hot heating system will require an increase in this value by 20-25%. Considering that the boiler is chosen for natural gas, it must be taken into account that the pressure drop in the gas main entails a decrease in boiler power by 15-20%. Thus, the power reserve of the boiler must also be increased by this amount. As a result, we have 28-30 kW.

Table 2. Comparative analysis of the use of the most popular types of fuel for heating a private house with a total area of ​​200 sq. m with heat loss of 30 kW.

The principle of operation of an autonomous gasification system

A volumetric tank is buried in the ground at a distance from the house (in warm areas it is installed on the surface of the earth). A pipeline is laid from the reservoir neck to the house, the outlets from which lead to the kitchen and to the boiler room. The tank is filled to 85% of the volume with liquefied gas from a special gas tank, which comes to you from 1 to 3 times a year. The poured liquid propane-butane begins to evaporate and the vapors (gas phase), passing through the reducers, under a low pressure of 30 mbar, enter through the pipe to the consumption devices.

Since the gas is in a liquefied state in the tank, and already in the form of gas is supplied to the heating devices, heat is required to evaporate it. In its absence, the intensity of evaporation of liquefied gas is significantly reduced and its pressure decreases. The process of converting liquefied gas from a liquid directly into a gas is called regasification.

From 1 liter of liquefied gas comes out 0.25 cubic meters. m of gas in a gaseous state. Regasification in surface tanks occurs under the influence of ambient heat, therefore, in winter time at low air temperatures, the productivity of such reservoirs is significantly reduced. In underground reservoirs, regasification occurs due to the thermal effect of the surrounding soil, while in winter the reservoir receives a constant heat flux from the depth of the soil. The temperature of the gas in the tank does not fall below +4C, therefore the evaporating capacity of such tanks is higher.

An autonomous gas supply system consists of a tank for liquefied gas, a safety valve, a drain valve, a level gauge, medium and low pressure reducers, and a piping system. The design, construction and operation of the system is carried out by specialized organizations that have all the permits and licenses.

Safety and reliability

Safety and reliability is what the consumer of any product or service is primarily interested in. In the case of autonomous gasification systems, safety and reliability must be considered in two aspects: the equipment itself and the fuel supply.

As a rule, there are no problems with equipment: its maintenance is carried out by qualified personnel according to special regulations. Each installation at the stage of its “birth” receives a serial passport, which is registered with the relevant authorities and then displays the entire history of its life. All such installations have a wide range of protection systems. Only licensed workers can be allowed to install and maintain them, and the owner of the house has the right only to visually take meter readings (by the way, do not forget to clear the container hatch from snow and look at the level gauge).

In general, such equipment is quite reliable - its service life is 20-30 years. Some elements are subject to forced replacement after the end of the standard service life. This service approach is familiar to many in the car maintenance system.

The subconscious fear about the hidden power of liquefied gas is born from rumors, myths and horrors of television reports from the places of explosions and fires of gas cylinders. There is a clear lack of reliable information, because an explosion or ignition can occur only in the event of some deliberate action or non-compliance with elementary safety rules.

But the situation with the supply of liquefied hydrocarbon gas for the majority of owners of private households is ambiguous. This is not diesel fuel, which you can buy at any gas station. Liquefied gas is supplied only by specialized organizations.

Advantages of autonomous gasification.

Firstly, it is the comfort and ecology of gas heating. Gas is provided not only by the boiler itself, but also by the stove. No soot, no ash to remove (as with coal), no sulfur oxide, no odor (as with diesel). Liquefied hydrocarbon gas, when it hits the ground, does not destroy it like diesel fuel.

Secondly, it is complete autonomy and, as a result, independence from gas pressure drops in the pipe, which is quite common in centralized gas heating systems. Therefore, turning off the gas and freezing does not threaten your radiators.

Thirdly, it is economy. In terms of cost of energy carriers, systems with liquefied hydrocarbon gas are inferior to gas boilers, but win in comparison with liquid fuel boilers. To the virtues this method heating can also be attributed to the very low level of sulfur compounds and the stability of the gas pressure at the inlet. Therefore, boilers that run on liquefied gas are much more durable.

The autonomous gasification system on liquefied petroleum gas can also serve as a backup fuel for natural gas consumers during peak loads in the gas pipeline network or during an emergency shutdown of gas supply.

Autonomous gas supply - how to make a system on your site? + Video

If you want to build a cottage, then you should definitely learn as much as possible about the autonomous gas supply of a country house. We will try to collect an exhaustive idea of ​​its advantages and disadvantages, we will also consider the scheme and nuances of design.

What it is?

Gas is the most popular and cheapest fuel used for heating private homes. It is not worth mentioning that this particular energy source is actively used for heating water, cooking, etc. Therefore, if you are going to build a country house, then gasification cannot be avoided. But what is an independent gas supply? This option is resorted to when it is not possible to connect to the central wire.

In the case of an autonomous system for a private house, a special tank filled with liquefied gas is buried in the ground, from where the fuel enters directly into the pipes. This design is also equipped with a special control system. As for the frequency of refueling, it is carried out as needed, usually it is required no more than twice a year. However, this indicator is influenced by a number of conditions, ranging from the number and quadrature of the heated premises to their purpose, because there is a difference whether you will heat the house every day or only on weekends.

Advantages and disadvantages of autonomous gas supply

So, let's start, of course, with the advantages of such a system. First, it is quite reliable and does not require any special care. So it is quite enough to simply carry out regular visual inspection for defects. Secondly, the equipment is able to withstand a huge temperature difference, reaching almost 100 ° C, namely from -45 to +50, so its use is relevant for a private house in absolutely any region, regardless of climatic conditions. In addition, it is completely independent of the central gas pipeline and, accordingly, the pressure in it.

The disadvantages include additional costs, because in this case you will need special equipment, the price of which is not small. You also need to constantly monitor the pressure in the system, otherwise you can be left without blue fuel at the most inopportune moment. And when choosing a place where the tank will be located, you need to make sure that transport will freely drive up to it, otherwise it will be very difficult to fill it. And of course, there can be no talk of any initiative in terms of installation or repair, because even a child knows that gas is a rather dangerous substance that can not only cause poisoning of the body, but also provoke a powerful explosion.

The system and its features

So, as already mentioned, autonomous gasification is independent of the central wire, and in this case the fuel is in a special container located underground at a depth of at least 1.5 meters. This tank is also called a gas tank. From it, respectively, through the pipes the substance enters directly into the house. One of the main parameters is productivity, that is, the amount of gaseous fuel produced from liquefied gas. Naturally, the more it is, the better.

In some cases, several houses are connected to the system, and then, of course, its performance is not enough - in order to increase it, a special evaporator is installed.

It should also be noted that the factors affecting the amount of fuel obtained are the temperature and surface area of ​​the liquefied gas. That is why the gas tank is buried at least one and a half meters into the ground, because at such a depth soil freezing is not terrible, and the temperature remains approximately at the same level throughout the year. That is, there is only one way to regulate the capacity, and in order to increase it, a wider tank should be chosen.

Choosing a gas tank

As you can see, this barrel is one of the main elements of an autonomous gas supply system for a private house, and we simply have no right to treat its quality negligently. They come from different manufacturers, as a rule, Polish, domestic, Italian and Czech. Of course, their cost will be slightly different. There are also ground variants, mainly of Czech production. Their cost is somewhat overpriced, but in this case you will avoid earthmoving, however, such equipment will not always be able to withstand harsh winters, and then additional heating will be necessary. In addition, if the quality of the metal is not good enough, then corrosion may occur, which threatens to provoke a powerful explosion.

Still gasholders are vertical or horizontal. It is better to give preference to the latter option, since in such tanks the pressure is distributed more evenly. Be sure to pay attention to the following parameters - volume, shape and material. Performance depends on the first two, and security depends on the latter. Naturally, it is better not to spare money, but to turn to professionals, they will make all the necessary calculations and installation. So you can save time and, possibly, even money, because incorrect calculations can cost you at least additional material costs.

The procedure for gasification of a private house

Now it's time to get acquainted with the order of work. So, there are two ways to solve this problem. You can contact a private company that will take care of all the issues related to the design and collection of the necessary documentation. Of course, the services of such offices are not free. You can do this on your own. If you chose the second option, then you should go to the local oblgaz structure, taking with you your passport, documents for the land plot, as well as specifications heating systems, and write a corresponding application. After you visit a specialist involved in the development of specifications.

When designing an autonomous gas supply for a private house, some requirements must be observed. For example, a container in which liquefied gas is stored must be located at a certain distance from various structures. The distance is observed as follows:

• to the fence at least 2 meters;
• more than 10 m recede from residential buildings, and 5 m is enough from trees and non-residential premises;
• the distance to wells, hatches, as well as wells should be at least 15 m.

Also, specialists study the properties of the soil, in accordance with its indicators, specifications are compiled. After, having written another application and collecting a number of documents (technical characteristics of the evaporator and tank, site plan, external gas pipeline and, of course, the conclusion of previous specialists), you should also contact the gasification design company. Of course, this organization must have the appropriate license. As a result, after registering with a specialized office, you will receive permission to carry out further work.

Only after this paper routine can you start installing the tank and connecting it directly to the gas pipeline of a private house. Moreover, this stage should be carried out only by highly qualified specialists. The only thing you can do yourself is earthmoving, thereby saving some money, but wasting time.

How autonomous gasification works | How it's done

Not all settlements are connected to the "benefits of civilization". Even new cottage settlements and private houses built near the city limits are often left without a central heating system. There is no corresponding project in the master plan, it is unprofitable to supply gas there or it is too expensive to do it - there can be many reasons, but people still need heating. There are several ways to provide your home with heat, and one of them is an autonomous gas supply system.

Autonomous gasification has long been actively used in Europe - not only for heating private houses, but also for industrial buildings. After the construction boom of cottages began in Russia, autonomous gas supply began to be actively used in our country.

The scheme of operation of the system is quite simple: in accordance with the design standards, a container (gas tank) with a volume of 1,750 to 10,000 liters is buried near the house or any other object. Only the neck of the tank remains on the surface.

The capacity of the gas tank depends on the expected needs. Designers calculate the loads of the boiler house for heating the house, heating hot water and cooking. If it is planned to gasify several houses at once, then, accordingly, the calculation goes to all objects.

A gas pipeline is laid from the neck of the tank, and branches are already being made from it to the boiler room and to the kitchen. The gas pipeline is laid at a depth of at least one and a half meters, in a trench with a sand cushion. Special transport fills the gas tank with liquefied hydrocarbon gas (LHG). The liquefied fuel then turns into a gaseous state. The gas passes through special regulators and at reduced pressure (30-50 millibars) goes through the gas pipeline to the boiler room.

LPG is a universal synthetic gas, also known as liquefied petroleum gas propane-butane. It is obtained from oil refining. LPG is considered the most suitable and environmentally friendly fuel for boilers. There are few sulfur compounds in it, and therefore the combustion of gas occurs with greater efficiency and without emitting odors. In addition, when using LPG, expensive boilers are much less susceptible to corrosion.

A separate plus of autonomous systems running on LPG is that they can be used even in places remote from main gas pipelines. Because the refueling of the tank is carried out with the help of special transport, which can literally reach anywhere.

Where natural gas is not available, LPG will be the most economical fuel. Compared to diesel fuel or electricity, the benefit can be up to double.

And of course, the most important question is how safe is the autonomous gasification system? Answer: so much so that it is considered one of the most reliable methods of heating. If the system is installed by specialists, then it will last at least 20-30 years. And serious problems can only be caused as a result of targeted intervention. It goes without saying that the installation and maintenance of an autonomous gas supply system can only be trusted by those organizations that have the appropriate licenses. It is also worth giving preference to those companies that provide a "full cycle" of services: design, installation and production of fuel storage facilities.

Depending on the specific object, as well as on the number of houses that need gas, various schemes and sets of equipment are used. All this is developed by engineers of the heating company. Autonomous gas supply will easily cope with such tasks as heating a restaurant, car service, warehouse or mini-village.

Now you also know how an autonomous gas supply system works.

Autonomous gasification: pros and cons

Before you carry out autonomous gasification of your home or other object, you should carefully study all the advantages and disadvantages of such heating.

The disadvantages of autonomous gas supply include the following points:

• the need to constantly monitor the state of the gas tank for possible gas leakage, as well as the obligation to monitor the remaining gas in order to avoid negative consequences;
• the likelihood of malfunctions of the gearbox, into which water can enter, which will disable the entire system autonomous heating. However, such problems can be prevented by a more careful approach to the choice of a gas tank. Modern Choice such equipment requires a thorough study of all the characteristics of the products offered and their correlation with the expected operating conditions, from the type of soil to the features of the gas-consuming installation;
• a narrow circle of gas suppliers, which puts those who want to have autonomous gas heating in a dependent position;
• high cost of autonomous gasification measures, which involve the purchase of expensive equipment and payment for equally costly works and services. Therefore, initially, everything should be well thought out and assessed the cost of an autonomous heating system. In this case, all work on the assembly and adjustment of the system must be carried out by appropriate specialists. About how to independently establish gas supply in your home, and there can be no question! Think safety!

The advantages of autonomous gas heating are:

• saving. Heat energy obtained from autonomous gas supply is cheaper than electrical energy, as well as energy generated by burning diesel fuel. Thus, the cost of autonomous gasification is gradually paid off by reducing heating costs;
• freedom from main supply systems. There are no gas pressure drops in the system, and cases of unexpected shutdown;
• Efficiency of design work and installation of a gas tank in relation to the time of connection to the main gas supply network. If desired, the tank can be installed in one day, and the whole process takes 3-4 days;
• independence of the possibility of installing a gas tank from the location of the gasified object;
• environmental friendliness. The burnt gas contains almost no hazardous substances, and the tank with it is installed at a reliable distance from the object;
• a wide scope of liquefied gas, with which you can not only heat the house, but also supply it with electricity (naturally, by installing additional equipment), as well as cook food;
• individual project depending on your wishes;
• cost-effective maintenance of an autonomous gas heating system, the use of which for a long time does not require additional involvement of specialists. The system, installed by professionals and assembled from high-quality high-tech equipment, is able to work for more than two decades;
• increased service life of associated equipment involved in the operation of the autonomous gas supply system;
• system flexibility. No need to coordinate the installation of additional equipment;
• increased environmental friendliness. LPG completely evaporates during combustion and does not emit harmful substances.

Gas / Gasification in the Moscow region

Moscow region authorities promise to speed up the gasification of the region's settlements. Acting Governor of the Moscow Region Andrey Vorobyov said that by the spring of this year new program, which will indicate the addresses and specific terms of gasification. Its implementation will allow in a short time to bring the gas pipe up to the intra-settlement streets.

However, at the finish line, when the long-awaited gas pipeline will pass next to the household, the residents of the Moscow region will face the need to solve a standard problem - bringing gas to the house. For most of us, this is the first experience of gasification, and we approach it unprepared, with many questions: “How to connect to the pipeline, whom to contact, how much will it cost?”

The Podmoskovye correspondent conducted his own research on what steps you need to take before the “blue light” lights up in your kitchen, as well as who is better and safer to contact for work.

Gasification in the Moscow region: an example of fraud

Unfortunately, no one is immune from deception, even highly educated and famous people often fall for the tricks of scammers. So, in one of the elite cottage settlements, the client decided to install gas to his house. It was not necessary to pull the pipe from afar, it was already walking next to the site. With one of the numerous companies found on the Internet, an agreement was signed for connecting to gas. The contractor took upon himself all the work and all the worries, which is called "turnkey", for which he asked for a lot of money.

On reflection, the applicant agreed and made an advance payment of 25% of the agreed amount. For this money, he completed the installation of the gas pipeline, after which they offered to pay the remaining amount, promising that the gas would be launched in the near future. At the request of the customer to show the agreed project, and then the rest of the documents, the answer was that there was no need for this, the gas would be released anyway. After that, the applicant, doubting the contractor's integrity, decided to apply to the operating organization - Mosoblgaz.

There, they did not hear anything about the company that performed the work, no one contacted the gas workers with the project. As a result, the money paid in advance was lost, since equipment already laid without documents, properly and timely executed acts cannot be used.

In the above case, we can say that everything worked out "little blood" largely due to the fact that the customer caught himself in time. But it can be worse, and therefore, before trusting anyone, you need to carefully prepare: carefully study the gasification procedure, market participants and approximate prices for work.

Gasification procedure: specifications and project

The procedure for connecting to the gas supply consists of several stages. It all starts with obtaining technical conditions, which clearly state what will serve as a source of gas supply, whether it is one house or a collective building. It also indicates which gas-using equipment is installed, and other special conditions.

It is important that the procedure for obtaining technical specifications is free. Unfortunately, unscrupulous contractors in the estimate manage to charge their own tariff for this service, - explains the director of the branch of the State Unitary Enterprise MO Mosoblgaz Dmitry Yuryev.

After receiving the technical specifications, it is necessary to make a gasification project. It can be ordered both at Mosoblgaz itself and from any other contracting organization. The cost of such a project may vary depending on its complexity, as well as on the pricing policy of various companies operating in this market.

Further, the project must be agreed and registered with Mosoblgaz. Please note that the coordination of projects in the Moscow region is carried out exclusively at the Mosoblgaz State Unitary Enterprise. Coordination is paid, but registration is not, although the same intermediaries can take advantage of the ignorance of residents and take their price for it.

Gasification: how to build a gas pipeline and bring gas into the house

The next step is to obtain permission to build a gas pipeline from local authorities, if required. For example, it will be necessary to get a "go-ahead" if it is necessary to lay a pipe to a settlement or site several kilometers away. Mosoblgaz does not solve such issues, and various intermediaries are actively working here who are ready to “settle” the problem if it arises.

After obtaining permission, a contractor is hired to perform construction and installation work, who will physically lay a gas pipeline to the house, make internal wiring, and also supply all the necessary equipment - a meter, a gas alarm, a chimney. As a rule, one contractor is hired for the project, and for permitting, and for laying pipes, since this is easier than dealing with several firms, each of which may have its own idea of ​​\u200b\u200bhow exactly the work should be done on each of them. stages.

During construction and installation work, it is important to have all properly executed permits, otherwise all work performed, as in the above case, will be a waste of money and time. In addition, all equipment used requires appropriate documents.

Any part of which the gas pipeline consists, whether it be a pipe, a basement, a meter, a gas alarm, all taps, must have a product passport. All this is then put into a folder when you prepare the executive and technical documentation. You show it when you hand over the object to us, - says Dmitry Yuryev.

When, as they say, “the pipe has laid down on the pipe,” that is, the gas pipeline has been installed, it must be handed over to the regional operational service of Mosobl-gas. Apart from technical documentation, she checks the pressure in the gas pipeline, carries out pressure testing. This is necessary to make sure that the gas pipeline is safe before tie-in. This procedure is free.

Next comes the delivery of the gas pipeline, which is also free, although many contractors charge money for this. Then comes the cut. This stage requires costs, but again, not those that some firms can “draw”. And the last thing is the launch of gas, after which the gasification process is completed.

Mosobolgaz: a list of conscientious gasification companies

Mosoblgaz notes: we are ready to implement the entire project on our own. But if the customer has already decided to turn not to Mosoblgaz, but to other contractors, then it will be useful at least to find out what the history of the life of the selected company, which SRO is, whether it is on the list of fraudsters, and if not, then clarify whether it performed such work earlier. Then the probability of falling for the bait of scammers will be much less.

In connection with the increasing cases of fraud by unscrupulous contractors performing gasification of private consumers in the Moscow region, the State Unitary Enterprise MO "Mosoblgaz" posted on its website information about organizations united in the non-profit partnership SRO "Association of Builders of the Moscow Region", which have a certificate for admission to certain types of work.

Go to the list of companies engaged in gasification in the Moscow region and approved by Mosbolgaz.

What to do 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 still it is worth considering this option of gasification in more detail, since it has many advantages. We will tell you how the system works, which work units are included in the autonomous complex.

We will describe the specifics of the operation of a gas tank and bottled gas supply, as well as designate the rules for designing, designing and installing a local gas pipeline.

Gas stove connected to a liquefied gas cylinder is a common occurrence. By the same principle, blue fuel can be brought to gas boiler to provide heating and hot water to the entire house. You just need a larger container or even several tanks of liquefied gas.

The fuel in such systems is an analogue of natural gas, which consists of a mixture of butane and propane. This mixture is called LPG - liquefied petroleum gas.

But if people live in a house or cottage all year round, be sure to install an underground tank.

Gas tanks designed for installation underground are more in demand than above-ground models, as they provide a stable temperature for storing liquefied gas.

Although it is easier to install a ground 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. Above ground installations are also typically more expensive than their underground counterparts.

As a rule, ground models are installed where a large gas flow is not planned. The tank will be emptied periodically, so you need to think right away: to prefer a stationary or mobile option. Refueling of mobile models equipped with towing wheels is carried out as follows:
