Installation and installation of a gas tank for a private house: the procedure for designing and carrying out installation work

Mini gas holders

To reduce the service area of ​​such an installation, mini-gas tanks were specially developed, which have slightly different dimensions, but are in no way inferior to their “competitors” in terms of functionality, serviceability, and service life. Such a structure is appropriate for small household plots. You can buy a gas tank for a summer residence inexpensively, and if necessary, sell it - the demand does not decrease. Here is a list of favorites:

• model name - CITI GAS 2700 (Bulgaria);
• price - 150,000-220,000 rubles;
• characteristics - horizontal design, operating temperature varies from -40 to + 40ºС, epoxy layer, protection against metal damage;
• pluses - compact, convenient in everyday use, ideal for small personal plots of a private house;
• cons - none.

Here is the second modern gas tank for a compact house, no less efficient, reliable and in demand among the masses:

• model name - GT7 RPG-6.5 (Russia);
• price - 200,000 rubles;
• characteristics - 6.5 cubic meters, tank material - steel, quality assurance - up to 30 years;
• pluses - remote location, main networks, the presence of a pressure regulator, compact dimensions;
• cons - none.

The third model of mini-gas tanks belongs to the same brand, but has distinctive parameters:

• model name - GT7 RPG-3 (Russia);
• price - 145,000 rubles;
• characteristics - volume - 3 cubes, vessel material - steel, quality assurance from the manufacturer, service life - up to 30 years;
• pluses - reliable and high-quality products for a private house from a domestic manufacturer, compact dimensions;
• cons - high price.

What is a gas holder?

The technical classification of a household gas tank device defines it as a liquefied gas storage device. Thus, a household gas tank is a vessel designed for filling and storing liquefied gas.

Of course, for such purposes, a tank is used that meets the requirements for such installations.In addition, gas holders for liquefied gas are equipped with a full set of automatic means to ensure safety during the operation of hazardous vessels.

This is how one of the possible modifications of a household gas tank looks like - a tank for liquefied gas, widely used by private households as a source of cheap energy

From here, an explanation suggests itself: workers and employees of special organizations are called upon to install, put into operation and carry out periodic control of the gas tank. This is roughly comparable to the case of everyday life when a gas boiler or gas water heater is installed in the house.

Well, in addition to the reference: gas tanks are usually refueled with a liquefied mixture of propane-butane. These are low molecular weight hydrocarbons, a characteristic feature of which is an easy transition from a liquid state to a gaseous state. The frequency of the gas tank filling process, as a rule, is not more than 1-2 times during the calendar year.

We also recommend reading the article, in which we figured out in detail the issue of the cost of installing a gas tank on the site. More details - read on.

Gas consumption for heating

The main fuel is the result of mixing propane and butane. Each of these gases has its own boiling point. Accordingly, in the summer, the predominance of butane in the mixture will be optimal, and in the winter - propane!

When gas is pumped out of tanks in winter, a significant amount of butane remains in it. This is due to the chemical properties of this gas - at a positive temperature it evaporates, and in winter it turns into a liquid substance.

In general, gas consumption in a private house depends on its area, the number of heaters and residents who consume both heating and hot water.

Equally important is the degree and quality of insulation of the building envelope (walls, roof, floor, etc.)

Volume calculation

The widespread belief that large volume gas tanks can save a lot on heating costs is both right and wrong. On the one hand, the larger the capacity, the more fuel reserves can be made

This is especially important from the point of view that it is cheaper to procure fuel in spring than at the beginning of the heating season. On the other hand, the larger the tank, the more expensive it is and the more preparatory work needs to be done to install it.

To learn more about all the "pitfalls" of calculating the volume of gas in the storage, let's turn to the following example.

Let's take a house with an area of ​​200 m2. The calculations presented earlier show that in order to meet the needs of the house for heating, hot water, etc. 27 liters of gas per 1 m2 of usable area will be required. Accordingly, it is necessary to purchase a barrel with a volume of 5.4 m3.

Gas tank for a private house: pros and cons

The advantages of owning a gas tank in a personal household are obvious, we just have to state the facts:

pros

autonomy - the consumption of gas resources becomes available to you in full. Your personal gas pipeline system does not depend on line pressure. You are not afraid of accidents of the general gas pipeline. In addition, such equipment significantly affects the capitalization of your home;

environmental component - do you want to walk on snow-white snow in your country house, creaking on the paths? Then urgently refuse fuel oil, diesel fuel and coal. The almost complete absence of sulfur compounds in liquefied gas, and its complete combustion with enough air, guarantee you snow-white snow and clean air. Even if the gas tank fails, and the gas breaks out, then nothing terrible will happen. Liquefied gas quickly passes into the vapor phase and evaporates into the atmosphere. You don't have to worry about damaging the ground cover or seedlings;

extended life of your entire farm. Gas-fired boiler equipment always has an undeniable advantage in the form of a long service life over solid fuel or liquid fuel boilers. The fact is that the absence of sulfur favorably affects the interaction with the metal. Having no reaction with sulfur, gas equipment will work faithfully 30% longer compared to traditional heating units;

odorless combustion - modern gas equipment is ubiquitous in high-rise apartments. The processes of combustion of blue fuel in the devices proceed without the release of pungent odors, and harmful products are brought out through the chimney.

The disadvantages that a gas tank can give us are not so obvious. For the most part, they are all connected in one way or another with the increasing financial burden on homeownership:

Minuses

Price - financial costs for a full range of services for connecting a gas tank, which is called "turnkey", will cost the owner starting from $ 3,500. Additionally, you will have to buy control valves, gas analyzers and other metering devices. Ensuring the access of the gas carrier so that the delivery of gas and refueling of the gas tank is carried out without hindrance. Add to this the yearly maintenance;

Increased responsibility - the gas in the tank is an explosive substance. You should remember about safety measures and, if possible, bury the gas tank in the ground with the maximum distance from residential buildings. The minimum distance is considered to be 10 meters, the depth, as a rule, corresponds to the lower level of soil freezing. As we wrote above, limit the filling of the storage tank to no more than 85% of the volume. Remember, gas is a substance that can expand, especially in the summer.

Routine inspection - the gas tank requires regular service. Taking into account the passport data of the tanks, according to the current rules and standards, only specially trained persons who have passed certification are allowed to service. The entire system must be constantly monitored for gas leaks. Monitor the amount of it in the tank so as not to get into the situation of an empty tank with subsequent shutdown of the heating system. A telemetry module can become an assistant in solving many problems. As you can guess, this pleasure is not free, but the installation monitors and transmits information about the state of the equipment via the Internet or cellular communications;

condensate formations - evaporation occurs inside the gas tank, particles fall on the walls in the form of condensate, the process destroys the equipment and can gradually disable the tank.

Consumption of liquefied gas for home heating

Gas consumption in systems of independent gasification of houses depends on a large number of various factors, the main of which are:

• the desired temperature regime in the house, the air temperature outside and the duration of the heating period;
• wall, window, door, ceiling and floor areas. For example, the larger the window area, the greater the heat loss and gas consumption by the boiler;
• material and construction of walls, ceiling, floor, doors, type of glass packets in windows. For example, the thicker the walls, the better their thermal insulation properties. Heat loss through wooden walls is less than through brick walls with their equal thickness, and a double-glazed window provides greater energy efficiency when compared with a single-chamber;
• mode of residence (permanent or on weekends and holidays);
• number of residents. This moment determines the gas consumption for cooking and preparing hot water for the DHW system;
• the presence of a swimming pool;
• operation of additional gas-using equipment (gas generator, outdoor infrared heaters, etc.).

Heat supply cost calculator

The calculator allows you to calculate the sufficient power of the boiler and compare the costs of home heating with mains gas, liquefied gas from a gas tank, diesel fuel (diesel oil) and electric current.

The following data were used in the calculations:

• duration of the heating period - 5256 hours;
• duration of non-permanent residence (summer and weekends 130 days) - 3120 hours;
• the average temperature during the heating period is minus 2.2°C;
• the ambient temperature of the coldest five-day period in St. Petersburg is minus 26°C;
• soil temperature under the house during the heating period - 5 ° C;
• lowered home temperature in the absence of a person - 8 ° C;
• insulation of the attic floor - a layer of mineral wool with a density of 50 kg / m? 200 mm thick.

High-quality gas - lower costs

The cost of refueling a gas tank

Timely refueling of gas tanks with high-quality Kirishi gas at a respectable first-hand price is a guarantee of good operation of the independent gas supply system and long-term partnership with our customers.

Refueling a gas tank with high-quality gas is not only a guarantee of operation without various interruptions of an independent gas supply system, but also a comfortable operation of the heating system in winter. In order for the gas boiler not to stop, and the emergency gas electric generator to start reliably, you need to remember a few basic rules.

Carrying out installation work

The lion's share of installations of household gas tanks is traditionally performed in the underground version. Such installation is considered more acceptable from the point of view of safety, plus a hidden gas tank does not spoil the landscape view.

Also, taking into account the rather harsh climatic conditions of the middle lane, the installation of gas tanks in the underground version is given more preference. So there are fewer problems with maintaining the device in working condition at low winter temperatures.

How to install a buried tank

Having chosen a place suitable for all requirements on the territory of a private economy, they organize work on marking the site, installation and excavation. The dimensions of the future pit that should be used for the gas tank are determined on the basis of the reservoir documentation. The made pit is additionally prepared for loading the tank:

• strengthen the bottom;
• put at the bottom of the pit a frame for the foundation with anchor fasteners;
• pour the frame with concrete, including the base of the anchor studs.

After the concrete pour has hardened, the installation of the tank begins. Massive gas tanks may require a crane rental. Small gas holders are lowered into the pit using winches or similar tools.

The container lowered into the pit is placed on the anchor studs of the foundation, leveled along the horizon, using linings under the paws, and fixed. For fastening tanks, the design of which is without supporting legs, metal tapes or cables are used.

Electrochemical protection of gas tanks

At the next stage of the installation of the gas tank, work is carried out on the corrosion protection device. Conventional methods of protection are not suitable here. We need high-quality electrochemical technology. As a rule, one of two methods of electrochemical protection is used:

1. Active.
2. Protective

Active electrochemical protection is often used on tanks manufactured at Russian enterprises. This protection option is most effective for metal subject to corrosion (in particular, steel 09G2S). It is from this type of metal that Russian-made gas tanks are made.

Cathode protection is carried out by an electrical circuit, the power consumption of which is 0.75 - 0.90 kW.Quite a costly station for a private economy, but no other solution has yet been invented.

An alternative for an active protection station is a sacrificial anode/cathode system. This design also has its drawbacks, but saves the consumer from the cost of electricity. Used in conjunction with imported tanks. The principle of operation of such a system is based on the “interception” of active corrosion by a metal with an increased electronegative potential (for example, aluminum).

For both methods of electrochemical protection, appropriate calculations are required with an emphasis on the type of container, its overall dimensions and other factors. Calculations determine the place of installation of the electrochemical protector or the power of active cathodic protection. At the design stage of the gas tank installation, this moment must be taken into account.

Protector systems are seen as more attractive in terms of economy. But they can not be applied to all types of tanks.

Grounding and lightning protection

The functions of grounding gas tanks, in fact, can be taken over by electrochemical protection systems. However, a household gas tank must be protected from a lightning discharge individually in any case. With regard to the installation of the installation, the following actions are possible here:

1. Making a ground loop.
2. Installation and deepening of the contour along the perimeter of the pit to a depth of at least 1.8 m.
3. If necessary (for moving soils), reinforcement of the contour with reinforcing elements.

Ultimately, all installation elements included in the gas distribution system must be combined into a common ground loop, so that comprehensive protection is provided (according to PB 12-609-03). The value of the resistance of the common circuit is allowed at the level of 10 ohms and no more.

The lightning rod is installed at a distance of at least 12 m from the border of the gas tank pit and connected to the ground loop. The height of the lightning rod mast is not less than 7 m.

Design features and device principle

Autonomous systems are reservoirs designed to store gas reserves in order to eliminate dependence on the state and independently control the amount of utility bills for gas supply. Having completed one or two refills of the tank per year (depending on the volume of the gas tank for the house), you get the opportunity to safely use the gas stove not only for cooking, but also for space heating.

The capacity of gas tanks for a country house is different - from 2,500 to 20,000 liters, small containers are used in mobile installations. Since gas tanks need increased attention, a protective automation system must be installed that monitors the gas pressure in the tank, controls fuel consumption, and is responsible for the safe operation of the entire system. Even a mini gas tank can provide gas to a large private house.

Types of gas tanks

These devices have been in use for decades. Previously, they were large and cylindrical, adjustable in height and used to supply gas to entire urban areas.This type of system is called variable volume gas tanks, in a number of cities such installations are still preserved.

What is a gas tank for a country house today? Tank options are used to provide gas to private facilities, summer cottages, cottages, they are distinguished by their compact forms.

ground

Their installation is carried out on the surface of the earth. Such a gas tank is advantageous in that it is easier to maintain and easier to detect traces of corrosion and other damage. Do not forget that in the case of such an installation in winter, the air-gas mixture sharply loses its ability to evaporate, and the option implies additional measures aimed at ensuring safety.

Ground gas tank for a private house

The main condition that needs to be taken care of in the first place is that the sun's rays should not fall on the container. Although the body of the gas tank is able to withstand high temperatures, it is recommended to mount it in the shade for additional safety.

To save space on the territory, ground gas tanks are chosen of a vertical type with a small volume, connecting them to a common network.

Underground

At first glance, the installation of such a gas tank will entail additional financial costs associated with the operation of special earthmoving equipment. But the underground placement option will provide the installation with protection from cold air, an additional degree of security and constant gas pressure at the same level.

To protect the tank from freezing and mechanical damage, underground tanks are dug to a level of at least 0.6 m.With regard to the volume of gas holders, a container with a capacity of 2,500 to 10,000 liters can easily be placed on a suburban area without spoiling the appearance of the landscape. The tank is dug into the ground in such a way that only the neck remains above the surface, to which the unit is connected to perform refueling. Gas is supplied to the house through pipes.

vertical

Outwardly, they resemble large cans, they do not take up much space on the site. But if a large gas consumption is planned, then the tank is provided with an evaporator that helps to create the necessary gas pressure. This measure increases the total cost of equipment, increases operating costs.

Vertical gas holders

Vertical installation options are beneficial if gas consumption is planned for cooking and heating water in the summer, when the consumption of such fuel for such purposes is minimal.

It should also be noted that vertical tanks are in most cases intended for underground installation, so the cost of their installation automatically increases.

Horizontal

Horizontal gas tanks are chosen more often

The most common version of gas holders with a large area of ​​evaporation of the "liquid phase". In such a container, there is always the required amount of a gas-air mixture capable of creating the necessary pressure at increased consumption. To ensure the necessary evaporation, natural conditions are sufficient, additional devices are not required, which entails saving money. Horizontal installations can create the right level of pressure even during severe frosts. There is only one significant drawback - the installation will require a lot of free space.

Mobile

If you plan to use the country house not all year round, or if there is not enough space to accommodate a stationary gas tank, it is recommended to use the mobile version. With its help, you will provide gas to a country house in the summer season, and move the installation to another place for the winter. No special equipment is required for the installation of equipment, the free space of the site will be temporarily occupied. The cost of such gas tanks is quite acceptable, because their volume is only five to six hundred liters.

Mobile gas tank for a private house

Pros and cons of alternative heating and gas supply systems

In the heat supply system on diesel fuel, the cost of a container for diesel fuel is much lower; it is possible to install it in a separate boiler room. The disadvantages include the fact that heating boilers for diesel fuel are much more expensive; a separate boiler room is required to install the boiler; diesel fuel in the price per liter and in terms of calories is 1.5 times more expensive than liquefied gas; there is no possibility of connecting a stove. Advantages of the liquefied gas heat supply system: heating boilers are much cheaper; it is possible to install wall-mounted gas boilers with coaxial chimneys in the kitchen or bathroom; can connect gas stove; simplicity, reliability and economy of operation; less specific cost of thermal energy; a priori prestige of the system. Disadvantages of a heat supply system using liquefied gas: a tank for storing liquefied gas is much more expensive; above the requirements for compliance with safety rules during operation.Having considered the pros and cons of the two systems, my friends and I decided to install an autonomous gasification system at home. Let the installation be more expensive, but you can save on operation and increase capitalization, as well as increase the prestige of the house due to its gasification. Having studied the proposals of companies for the installation of gas tanks, we decided on the necessary set of options and installation work. Since the house will periodically remain without owners, we decided to additionally install a gas pollution detector and an electromagnetic shut-off valve. Such a security system will protect the house in the event of an emergency shutdown of the boiler. Gas holders are made mainly of steel with anti-corrosion (epoxy) coatings. For country houses, gas tanks are produced with a volume of 2700, 4850, 6400 and 9150 liters. For self-calculation of the required volume of a gas tank, they usually proceed from the average consumption - 25-35 liters per year of liquefied propane-butane per 1 m2 of the heated area of ​​\u200b\u200bthe house. But this calculation takes into account only heating. With the additional use of gas for the preparation of hot water, the volume of consumption increases. Many homeowners, trying to save money, choose a smaller gas tank (2700 liters), rightly believing that they will be able to refuel more often. But it should be borne in mind that the choice of a tank directly affects the power of the boiler equipment that will use propane-butane from the selected tank. Without going into the physics of phase transitions, we point out that the volume of the reservoir depends on the intensity of evaporation and the amount of gas entering the boiler plant.There is a direct relationship between the geometric dimensions of the gas tank, the level of its filling, the temperature of the soil around the tank and the maximum power of the boiler. A powerful boiler requires a large gas tank. So, for a boiler with a capacity of up to 15 kW, a gas tank with a volume of 2700 liters is enough, for a boiler with a capacity of 15-40 kW, a capacity of 4850 liters is required, for a boiler with a capacity of 40-60 kW - 6400 liters.

What is a gas tank

In fact, this is a gas tank, which is necessary for heating rooms of various sizes. However, the functions of the gas tank are not limited to this; in addition, it is always hot water and electricity generation in the house. If the owner of a summer house or a private house acquires a gas tank, he is able to immediately solve a number of problems that are relevant to him. Capacitive gas is cheap, and its production provides heat for rooms up to 20 square meters. Autonomous turnkey gasification of a private house is considered a particularly popular service.

Gas tank device

The container filled with gas has different sizes, due to the individual needs of consumers. The gas tank device can be filled with propane, butane or methane, which is determined by the pricing policy. Having used up the gas tank during the heating season, it needs to be additionally refueled, so the cylinder itself is intended for repeated use.

As for the design features, the gas tank itself for the home can be made of steel and reinforced concrete with a variable or constant volume. In the first case, we are talking about the presence of a vertical cylinder and water and a bell located in the lower part.However, in the modern world they come to the conclusion that such models are obsolete and become uncompetitive. In practice, the use of structures with a constant volume is welcomed.

The principle of operation of the gas tank

Before heating a cottage or a residential cottage, it is recommended to figure out on what principle gas tanks work for a country house

It is important to ensure not only the serviceability and correct installation of the structure itself, but also its safe functionality, according to the technical documentation. Installing a gas tank is a job that should be done by specialists in their field, and not by a private individual

The basic principle of operation of the gas tank is as follows: after evaporation, the propane-butane fraction enters the reactor, where it receives sufficient pressure for further redistribution along the gas pipeline junction to the consumer. If you correctly calculate the area and buy a suitable gas tank, its contents should be enough for a year of regular heating of residential premises without additional refueling.

Requirements for installing a gas tank

Out of ignorance, you can perceive gas tanks for a private house as a classic version of a gas storage. In reality, this is a complex system necessary for converting gas into fuel required for the operation of household appliances, space heating. When installing such an alternative to a double-circuit boiler, the following rules and concepts should be considered:

• the distance from the gas tank to the residential building is at least 10 m, to the buried foundation - at least 2 m;
• the area for the installation of the structure must be flat;
• after filling the reservoir, it is forbidden to concrete, plant the site;
• location on the site, the distance to the fence is not standardized;
• installation of a gas tank requires a permit and a permit for underground work.
• installation of the gas tank is carried out by knowledgeable specialists;
• calculation of the volume of the tank, based on the dimensions of the heated area.

Pros and cons of a gas tank

This is a significant step that the homeowner should carefully consider, consult with knowledgeable people. If an autonomous gas supply to a private house is chosen, it is required to determine the advantages and disadvantages of operating such modern equipment. Studying the pros and cons of a gas tank, it is recommended to start with positive aspects that are relevant to all potential buyers. The main advantages are the following:

• provision of electricity, heat and hot water;
• a mobile station, the service of which does not cause problems;
• long service life;
• turnkey gas tank on self-sufficiency in 2-3 years;
• human safety;
• the possibility of obtaining a loan or installment plan from the manufacturer;
• delivery, quality assurance from the manufacturer.

Before installing a gas tank of one of the modifications, you need to additionally familiarize yourself with the main disadvantages of such an undertaking. It:

• the high cost of a gas tank, an additional fee for the installation of the structure;
• difficulties in finding a respectable and professional specialist for installation and installation;
• the risk of installation beyond the technical documentation of a previously approved project.
