Vertical gas tank: overview of models and turnkey installation features. Prices for autonomous gasification with a vertical gas holder Vertical or horizontal gas holder

Unlike conventional gas holders, such as AvtonomGaz gas holders, vertical gas holders have a vertical orientation - their height is greater than their length. A good example a vertical gas holder can be produced by the Italian company Antonio Merloni.

The dimensions force vertical gas tanks to be buried deeper than horizontal ones. The bottom of a vertical gas tank can be located at a depth of four meters underground. Companies that sell these tanks consider this quality an important advantage.

Why is the depth at which the gas tank is located important? In winter, it is colder near the surface than deep underground. Technical standards adopted in Russia require that household gas tanks be buried to such a depth where even in severe frost the temperature does not drop below zero. This is necessary in order to prevent condensation of the liquefied gas.

Such requirements apply equally to both horizontal and vertical gas holders. However, vertical gas tanks sink deeper than horizontal ones. This gives their suppliers a reason to claim that vertical tanks withstand frost better than horizontal ones.

Indeed, European manufacturers of vertical tanks promise uninterrupted operation of their products at temperatures down to -40°C. However, can their promises be trusted? If we are talking about Russia, the answer will be a resounding “no.”

Vertical gas tanks can withstand this temperature only when using special fuel, which is not available in Russia.

Sellers of vertical gas tanks never mention this important detail. If in Europe for autonomous heating While pure propane is used in houses, in Russia houses are heated with the same gas mixture that fuels cars. In addition to propane, it contains a significant amount of butane.

The problem stems from the fact that propane and butane have different partial pressures. In a vertical gas holder, this leads to the fact that the components of the gas mixture evaporate in turn: first only propane, and then only butane. Since pure butane requires different boiler adjustments, once the propane evaporates, the boiler will likely shut down.

Horizontal gas tanks, such as the AvtonomGaz gas tank, do not have this disadvantage. The fact is that a horizontal tank has an average gas evaporation surface area that is approximately three times larger than a vertical tank of the same volume. The large area speeds up the evaporation of butane and prevents the supply of pure butane.

European vertical gas tanks are not designed for the cold winters of the Moscow region, nor for the specific composition of the fuel available in our latitudes.

A good alternative is AvtonomGaz gas tanks. They are designed taking into account all the features of operation in Russia, starting with the cold climate and ending with typical problems during transportation and installation. .

(Fig. 32.1 - 10 reasons why you
do not buy a vertical gas holder)

1. The decisions of the company's Italian engineers seem weak to you "Antonio Merloni Cylinders Ghergo Group S.p.A." ("Antonio Merloni"): in the field of autonomous gasification, compared to other manufacturers.
   
2. Have you ever compared the weight of a gas tank with the weight of containers from other manufacturers? Its impressive weight, resulting from the thickness of the tank wall and the quality of the material, which is a clear criterion for reliability and long service life, does not tell you anything.
   
3. You fell for the bait of the advertisement “Autonomous turnkey gas supply” and the differences in price categories are not in favor of vertical gas tanks "Antonio Merloni Cylinders Ghergo Group S.p.A.", and you do not pay attention to global differences in configuration.
   It doesn’t bother you that other manufacturers don’t have:

• Two-stage reduction.
• Three-component anode-cathode protection against the effects of stray and inductive underground currents.
• Protective bag "Marsupio" made of durable electrically conductive polymer.
• Concrete-alkaline base, not afraid of underground currents, loads and acid-base environment.

1. You don't care at what temperatures in winter time a horizontal gas tank will operate.

(Fig. 32.2 - Antonio Merloni leader
in the field of autonomous gasification)

1. You do not trust photographs and articles about the cemetery of horizontal gas tanks (). You don't care about the reasons why people get rid of tanks after 10 years and stockpile them, thereby fueling the market for used horizontal gas tanks. You don’t ask yourself the question: “Why is there not a single used vertical gas storage tank on the market?”

1. You are a persistent person and are not afraid of “pop-up” horizontal gas tanks. You are not afraid of work to eliminate “floating”.
   
2. You are not afraid of additional costs for installing evaporators to horizontal gas tanks to evaporate gas at temperatures below -20º.
   
3. You completely and completely trust your friends, neighbors and relatives who have installed horizontal tanks and claim that they have no problems with autonomous gas supply.
   
4. The minimum payment today is important to you and the service life of the equipment purchased for this money is not important.
   
5. You trust more promoted products - equipment with massive advertising, rather than equipment with the best technical characteristics.

These reasons take our paths in different directions, but if you still need a truly reliable and high-quality autonomous gas supply system, come back... and who knows, perhaps you will no longer find yourself on the list of reasons “AGAINST”.

Not all dacha areas are provided with centralized gas supplies. Heating a house with electricity is expensive. A good alternative is autonomous gasification. If you are not satisfied with the group of cylinders, then the solution will be a gas holder - a special tank that is filled with a mixture of liquefied hydrocarbons.

We will help you choose the optimal gas holder for your dacha. The article we presented describes in detail all the varieties that are actively used in suburban areas. A detailed description of the models will give an idea of ​​the features of the installation and use of containers for autonomous gas supply.

A gas holder is not only a container for storing the fuel mixture, but also a place where the liquid phase transforms into a gaseous state for further supply to the heating main under constant pressure. An important point in a standalone device gas system is a competent choice of gas tank, which requires calculation of its technical parameters.

To determine the volume of the container, the heated area is multiplied by the average amount of fuel consumed by boilers with an efficiency of 60 to 70%. It is approximately 17 liters for winter, when there are few days with very low temperatures.

If winters in the region are consistently severe or the dacha has heated floors, a pool, the water in which needs to be heated, the calculated volume is increased. In summer or in the off-season, 3.3 liters is enough to heat 1 m².

Propane-butane, used in a separate gas supply system, has a high calorie content, and therefore emits up to 3 times more heat during combustion than natural gas

To operate a mini-gas tank or a tank whose volume does not exceed 10 tons, no permission from Rostechnadzor is required, provided that the SNIP requirements for installation are met, and the power of the heating devices is not more than 100 kW. If you are not satisfied with this power and need to exceed it, then you will have to obtain a permit.

There is also no need to ask for consent from the owners of neighboring plots if communications will not take place in close proximity to the boundary line. In any case, in order to avoid any misunderstandings, it is good to have a quality certificate in hand. It must be obtained from the company that sold the equipment and has a license to install it.

Main components of the gasification project

Not every place on the site is suitable for installing a propane-butane tank. In order for all conditions to be met, it must have the appropriate dimensions. The main thing is that the tank needs free access, otherwise its refueling and maintenance becomes impossible.

When choosing a place for a gas tank, you should take into account that the gas tanker has a hose no more than 24 m long. In accordance with SNIP, you need to retreat about 2.5 m from the perimeter of your household, and if there is a source of water intake, then the norm provides a distance of 5 m to it

All communications can only be laid underground. The container itself should not be located under a driveway or other road.

The optimal distance from the road to the tank is 5 m. You should retreat at least 8 m from household buildings on your site. To the foundation of the house - 10 m, and from the neighbor's house - 20 m. The plate with the factory data should be in sight. Rules for choosing a location for a gas tank, dedicated to this issue.

It is allowed for the installed tank to rise above the ground by a maximum of 0.6 m. It must be grounded, and if static voltage is present in the area, measures to protect against electrochemical corrosion are necessary.

In terms of autonomous gasification, it consists of a tank manufactured and passed all stages of testing in the factory, pressure regulators, protection, and a gas pipeline. The protection consists of magnesium electrodes located at a distance of about 0.35 m from the container. The purpose of the condensate collector is to collect liquid butane, which then evaporates on its own.

The gas pipeline is assembled from pressure polyethylene pipes. before entering the house, mounted from metal pipes and equipped with a shut-off valve and a bellows-type compensator. The internal pipeline is equipped with thermal shut-off valves.

For this, a pit is prepared, at the bottom of which a cushion of sand and gravel is placed. Next, a monolithic base with a height of at least 160 mm is poured. Without this, the unit may be squeezed out of the pit groundwater. Sometimes the tank is immediately fixed to a finished reinforced concrete slab, and then the whole thing is lowered into a pit.

After fastening the tank, it is coated with a special lubricant that protects the metal from corrosion. Next stage- anodic-cathodic protection device. After this, the gas pipeline is laid and the pit and it are filled with soil.

Types of gas tanks for summer cottages

Gas tanks for suburban areas are both stationary and mobile. Stationary tanks are divided into above-ground and underground. For a home where people live permanently, a stationary tank is more suitable, and in the case of a summer house intended for seasonal use, it is rational to use a mobile option.

Ground Models

Ground gas tanks are characterized by ease of installation, since there is no need to excavation. The reason for the unpopularity of this option is that the fuel mixture evaporates very slowly at low temperatures. Therefore, the tank must not only be insulated, but also equipped with evaporators.

A small ground-based gas holder is the best temporary option for a dacha even if it is planned to be connected to a central gas main. You can use equipment designed to operate the highway in the final version, but you need to configure it to liquefied gas

For one country house it is irrational to do this, but if a large-capacity reservoir is used to provide fuel for an entire holiday village, this option is better. This is due to the fact that the decision to bury a gas tank with a volume of up to 6 tons m² in the ground will cost much more.

Options for underground placement

Underground tanks are placed in the ground below the freezing point.

This solution has advantages:

• the design of the site does not suffer;
• there is no need for additional equipment, maintaining stable evaporation of the gas mixture.

Underground reservoirs are used to supply gas to a village consisting of several houses. When installing a gas tank underground minimum distance from the ground level to the top point of the tank - on average 0.6 m. This parameter is greatly influenced by the climatic conditions of the area.

Since the underground tank must last a fairly long period, estimated in tens of years, it is important to choose a company with experienced craftsmen for its installation

A high-quality gas tank should be equipped with a high neck, which will allow it to be placed at the required depth. This will make it easier to periodically check the tank walls and welds for strength.

The tank must have walls with a minimum thickness of 6 mm and a thickness of the anti-corrosion epoxy polymer shell of at least 1 mm. The company selling the tank must present a certificate confirming that the product meets all requirements, as well as permission from Rostekhnadzor for its use.

Features of mobile gas tanks

A mobile tank with a volume of about 500 m3 is placed on a trailer. Connecting such a gas tank to the gas main is not difficult, and this operation is performed very quickly.

In fact, this is the same gas cylinder, only of a larger volume and having a gas heating system. This amount of liquefied fuel can be used to heat small dacha throughout the winter.

A small mobile gas tank for a summer residence is equipped with all the necessary fittings: valves - safety, filling, with a plug, with an indicator tube, as well as a pressure gauge. There is also a gearbox with a throughput capacity of 4 kg/hour and a level gauge

Such mini-tanks are compact - about 2 m long and 0.6 m in diameter. Their service life is quite long - up to 25 years.

If gas is needed solely for cooking, then this volume will be enough for 2 years. To use the house year-round, you will need a tank with a capacity of 2.5 tl., but when you also need to heat outbuildings, the storage size will have to be increased.

Mini tanks and their advantages

If we compare a miniature gas tank with a volume of 500 or 1000 liters with its large counterpart, we can note the following advantages:

1. It is much cheaper, so it has a shorter payback period.
2. You can install it yourself.
3. The container does not need to be hidden in the ground, and this significantly reduces installation time.
4. There are no strict requirements for the installation location. Clause 8.2.3. SP 62. 13330. 2022 states that a mini-reservoir can be placed directly against the wall of the house.
5. Gasification using such a gas tank is carried out very quickly - it only takes about 2 hours.

There are many advantages when compared with conventional gas cylinder. The main thing is that the gas holder is not explosive. The valves included in its package do not allow pressure to rise above the established norm.

Availability measuring instruments guarantees that when refilling the container, no more liquefied mixture will get into the container than it should. Since the mini-tank replaces a dozen standard 50-liter cylinders in volume, it is not refilled often

To replenish gas mixture reserves, it is not necessary to visit a gas station. If the gas tank is not installed on a trailer, but simply on a site near the house, then it can be refueled locally.

Unlike a cylinder, it can supply gas not only to the stove, but also to other more powerful equipment. Due to the fact that there is a level gauge on the tank, you can always find out how much mixture is left in it. This allows you to plan refueling in advance.

Vertical gas tank installations

Depending on the design features Underground gas tanks for arranging a dacha are divided into horizontal and vertical, which take up 3 times less space than horizontal ones.

This option is well suited for country housing, with a small local area. Ideally, it has a high neck, then it is buried to a depth of approximately 4 m. This will help avoid gas condensation during cold weather.

If 2 or more gas tanks are connected to each other with a common pipe, the total amount of gas will increase. Therefore, if the need for gas increases, it is not necessary to buy a new, larger tank

While as fuel is consumed from a horizontal tank, the area of ​​gas evaporation decreases, in a vertical gas tank, when the mixture level is lowered, the area of ​​the mirror remains constant.

Despite the lower productivity, this is a serious advantage, but due to the considerable height of the container and the depth of freezing of the ground, a lot of effort will be required to prepare the place for it.

Models of this type are suitable for country houses, the area of ​​which does not exceed 150 m². Good vertical gas tanks are produced in Italy, in particular, those produced by the company. They are equipped with a thermal protective layer that allows you to maintain a stable temperature during extreme cold.

Vertical tanks from the Bulgarian company CITI GAS are also popular. The model range consists of tanks with a volume of 2700, 4800 and 6400 gas liters. The gas tanks of these two companies differ not only in volume, but also in the color of the tanks and brand names on them.

Bulgarians paint their gas tanks blue and put the inscription CITI GAS and the volume on them. Italian tanks are green

The cost of vertical tanks is higher than that of horizontal samples. They effectively supply the gas mixture in the temperature range -40 – +40⁰. Their service life is 30 years.

Horizontal gas tanks

Horizontal gas tanks are more productive than vertical ones. There is one caveat - this indicator is unstable. As soon as the level of the gas mixture drops to 1/3 of the volume, it begins to fall, so the system cannot function stably without a special reducer.

Horizontal tanks are effective for heating a house with an area of ​​200 m² or more or several buildings at once. To install a horizontal tank, a shallow pit is prepared.

Its volume must be taken 20% more than the estimated fuel requirement. This is necessary to ensure that there is enough gas to maintain productivity after its volume has been reduced to a critical value.

From a technical point of view, the gas tank has simple design. Gases are supplied into one of the technological holes, and through the second fuel under pressure goes into the heating system. For dachas, the simplest tanks are used, with a capacity of 0.5 to 10 t. l.

The metal body of the gas tank can withstand pressure no higher than 1.8 MPa. Antonio Merloni is also a leader among manufacturers of horizontal units.

There are also units on the market from the Czech company Deltagaz and the Polish company Chemet. Normal functioning of these tanks is possible even in unusual situations and in the harshest winters.

Detailed characteristics of gas tanks of domestic, Czech and Italian production. We recommend that you read the useful information.

Features of filling gas tanks with a mixture of gases

The frequency of filling tanks with propane-butane depends on their volume and how intensively it is used. On average this is 1 – 3 times a year. The main thing is not to miss the moment when the balance is about 30%. Fill the tank not to the top, but not more than 85%.

The supplier of the gas mixture must have a license and special transport. The easiest way to fill mobile modifications of mini gas tanks for servicing summer cottages is because they can be transported on a car trailer. Before filling the gas tank, be sure to check the indicators of the devices.

You can get acquainted with the cost of installing a gas tank on a private plot, which we recommend reading.

Conclusions and useful video on the topic

The purchase and installation of any gas tank must be preceded by calculations of its volume and the payback time of the unit. The calculation results must be compared with alternative types heating and only then make a decision.

One of the main problems associated with content country houses- cottage, dacha, there is a need to solve such a seemingly simple question at first glance: “How, with what resources can we ensure the process of cooking, heating the house and outbuildings in the autumn-winter period, in order to feel comfortable in your home?

"Old-fashioned methods" - using firewood for stove heating, coal or fuel oil have practically become obsolete. Electricity has become expensive. Now there is an opportunity to take advantage of such a less expensive and more accessible energy resource as gas.

In case the construction or acquisition Vacation home is located away from centralized gas networks, you can use the system. Its main element is.

It is a cylindrical or spherical tank in which liquefied gas (compressed hydrocarbon gas (LPG) - most often a propane-butane mixture) is stored, equipped with special shut-off and measuring equipment.

Complete installation of equipment

Today, many companies, when buyers of a vertical gas tank contact them, offer to install it on a turnkey basis.

This means that in addition to the actual delivery of the gas tank, the supplier company offers a whole range of additional services, including the following items specified in the Agreement:

• A company engineer comes out to inspect and take measurements of the site;
• a gas container, filling equipment and elements related to the safety system for using this equipment are delivered;
• earthworks are carried out - a foundation pit is dug, a concrete or sand base is installed;
• install a gas pipeline (also underground) from the gas tank to the house;
• a pressure regulator and other measuring instruments are installed;
• fastening and installation of the entire system is carried out;
• A warranty service contract is drawn up (at the client’s request).

Thus, taking into account the above, it should be noted that the purchase of a horizontal or vertical type and this is quite a serious step towards comfortable living conditions in a private home. Therefore, before purchasing it, it is recommended:

• study consumer reviews on the Internet;
• seek advice from specialists who will advise based on the characteristics of your home (number square meters, degree of insulation, number of residents, etc.), required volume, model and manufacturer of the gas tank;
• When choosing a selling company, be guided by whether it has a federal license to provide services for the installation of autonomous gasification systems.
