Not all suburban tracts provide centralized gas supply. Electricity to heat the house - it's expensive. A good alternative is a stand-alone gasification. If you are not satisfied with a group of cylinders, the way out will be a gas tank - a special tank, which is charged with a mixture of liquefied hydrocarbons.
We will help you choose the best gas tank to give. In the present article, we have all kinds of detailed actively exploited in the suburban areas. Detailed specification models will give an idea about the features of the installation and use of tanks for autonomous gas supply.

Features installation of gasholder
Gazgolder - is not only a capacity for storing the fuel mixture, but also the place where the liquid phase It goes into a gaseous state for further supply to the heating pipe under constant pressure. An important point in the apparatus autonomous gas system is informed choice gas tank, which is needed for calculation of its technical parameters.
To determine the volume of the container, heated area is multiplied by the average amount of fuel consumed boilers with efficiencies from 60 to 70%. It is about 17 liters for winter days when the temperature is very low bit.
If the region is stable severe winter or in the country have heated floors, a swimming pool, the water in which you want to warm up, the calculated volume increase. Summer or in the off-season for heating sufficiently 1m² 3.3 liters.
Propane-butane used in the separate gas supply system has a high calorie content, and therefore heat of combustion releases up to 3 times greater than natural gas
For operation minigazgoldera or reservoir, whose volume does not exceed 10 m. L, no permission from the RTN not necessary, provided that the following requirements regarding the mounting SNIP and power heaters not more than 100 kW. If this power is not satisfied and it should exceed, then we need to get a permit.
To request the consent of the owners of the neighboring land is also not necessary if the communication does not take place in the immediate vicinity of the boundaries. In any case, in order to avoid further misunderstandings, good to have on hand a certificate of quality. It is necessary to take a company that sells equipment and has been licensed for installation.
The main components of the gasification project
Not any place in the area suitable for the installation of the tank with propane-butane. That all conditions have been met, it must be dimensioned accordingly. Most importantly, to the reservoir need free access, otherwise it becomes impossible refueling and maintenance.
When choosing a place under the gasholder be understood that bowser hose has a length not exceeding 24 m. In accordance with SNiPY from the perimeter of their home ownership need to withdraw about 2.5 m, and if there is a source of water intake, the standard distance is provided to it is 5 m
All communications are permitted only to lay underground. The very capacity should not be under the travel or the other way.
The optimal distance from the road to the tank - 5 m. From the buildings on the site should be economic destination withdraw at least 8 m -10 m to the basement at home, and the house neighbor -. 20 m. name plate data must be in the field view. Rules for siting a gas tank arrangement see the articleDevoted to this issue.
Resolved to set the tank rises above the earth for a maximum of 0.6 m. It's a must ground, and if the site contains static electricity, necessary measures to protect against galvanic Corrosion.
In terms of autonomous gasification consists of a reservoir made and passed all test stages in factory conditions, pressure regulators, protection of the pipeline. Protection is magnesium electrodes at a distance of about 0.35 m from the vessel. Purpose condensate - collecting liquid butane, which then evaporates by itself.
The pipeline is collected from the pressure polyethylene pipes. lay a gas pipeline before entering the house, assembled from metal tubes and equipped with a shut-off valve, and compensator bellows. Inner conduit mans termozapornymi valves.
For immersion gasholder prepared pit, at the bottom of which arrange the pillow of sand and gravel. Next, pour the monolithic substrate is not less than 160 mm. Without this unit can squeeze out of the pit groundwater. Sometimes the tank just fixed on the finished concrete slab, and then all together lowered into the pit.
After securing the reservoir covered with a special lubricant, which protects the metal from corrosion. The next stage - a device anode cathodic protection. After that laid the pipeline, and it is filled the pit with soil.
Types of gas tanks for garden
for gas tanks autonomous gasification suburban areas are both stationary and mobile. stationary container type are divided into elevated and underground. Housing, where there are constantly more suitable stationary tank, and in the case of villas, designed for seasonal use, efficient use mobile version.
Models for ground installation
Overhead gas tanks are characterized by ease of installation, as is required to perform excavation work. The reason for the unpopularity of this embodiment is the point that the fuel mixture at low temperature is very slow to evaporate. Therefore, the tank must not only warm, but also to equip evaporators.
Small ground gas tank - the best option for temporary cottages and in the event that it is planned to supply the central gas pipeline. You can use the equipment designed to operate highway in the final version, but it should be set up for liquefied gas
For a country house to do it is irrational, but if a large capacity tank used to fuel an entire housing estate, this option is better. This is due to the fact that the decision to bury the gas tank capacity of up to 6 m. M² land will cost much more.
Options for underground placement
Underground tanks are placed in the soil below the freezing point.
In this solution, there are advantages:
- does not suffer from the design area;
- eliminates the need for additional equipment, maintain stable evaporation of the gas mixture.
Underground tanks used for settlement gas consisting of several houses. When installing the underground gasholder minimum distance from the ground level to the top of the container -. 0.6 m in average on this parameter strongly influenced by the climatic conditions of the terrain.
Since the underground tank should last for a sufficiently long period, which is calculated in tens of years, it is important to set it to choose a company with a staff of experienced craftsmen
Qualitative gasholder for underground installation It must be equipped with a high neck, which will place it at the desired depth. This will simplify the task of periodic inspection of the vessel walls and the weld strength.
The reservoir should have a wall thickness of 6 mm and a minimum thickness of the anticorrosive epoxy polymer shell is not less than 1 mm. container firm-seller must present a certificate confirming that the product meets all requirements, as well as Rostekhnadzor permission to use it.
Features of mobile gas tanks
Mobile reservoir volume of about 500 m3 placed on a trailer. Connection of the gas tank to the gas mains are not complicated, and perform this operation very quickly.
In fact it is the same gas cylinder, only the larger volume and having a gas heating system. Thus the amount of the liquefied fuel may be heated a small cottage for the winter.
Small mobile gas tank to give all staff the necessary fittings: valves - safety, refueling, with a plug with an indicator tube and a manometer. There is still the gearbox-capacity 4 kg / h and the transmitter
Such mini-tanks compact - the length about 2 m and a diameter of 0.6 m Lifecycle them quite large -. 25.
If the gas is needed only for cooking, then this volume mobile gasholder enough for 2 years. To use the house year-round will require a tank capacity of 2.5 t. L., But when you need to heat more and outbuildings, the size of the repository will have to increase.
Mini tanks and their advantages
If we compare the miniature gas tank of 500 or 1000 liters with its larger cousins, it has the following advantages:
- It is much cheaper, so it makes little payback.
- His installations can be performed independently.
- Capacity does not need to hide in the ground, which significantly reduces installation time.
- There are no strict requirements for the installation site. Paragraph 8.2.3. SP 62. 13330. 2022 states that there is a mini-tank can be directly from the walls of the house.
- Gasification using this gasholder is very fast - only takes about 2 hours.
There are many advantages in the case of a comparison with a conventional gas cylinder. The main thing is that the gas tank is not explosive. Valves included in its packaging arrangement, do not allow the pressure increase above the established norm.
Availability of instrumentation ensures that when filling the tank does not fall over, liquefied mixture than is necessary. Since the mini tank volume replaces ten standard 50-liter bottles, filled in its infrequently
For replenishment of the gas mixture does not have to visit a gas station. If the gas tank is not installed on a trailer, but simply on the ground near the house, you can refill it in place.
In contrast to the bottle it can supply gas not only the plate, but also other more powerful equipment. Due to the fact that the reservoir has a transmitter, you can always see how much the mixture has been left. This allows you to plan ahead for refueling.
Vertical installation Gazgoldernaya
Depending on the design features of the underground gas tanks for decorating garden is divided into horizontal and vertical occupying 3 times less space than horizontal.
This option is well suited for suburban housing, with a small local area. Ideally, it has a high neck, while its buried to a depth of about 4 m. This will prevent condensation of gas during cold weather.
If two or more gas tanks interconnect common conduit, the total amount of the gas increases. Therefore, if demand for gas will increase, not necessarily to buy a new, higher-volume reservoir
While at least fuel consumption of the horizontal gas reservoir decreases evaporation area, the vertical level of the gas holder is lowered mixtures surface area remains constant.
Despite the lower performance, is a major advantage, but at the expense of a considerable height of the container and freezing depths of the earth, for the preparation of a site for it will require a lot of effort.
Models of this type are suitable for summer houses, which area is not more than 150 m². Good vertical gas tanks are produced in Italy, in particular, produced by the company antonio Merloni. They are equipped with thermal protector layer, allowing you to keep a stable temperature during the intense cold.
Popular and vertical tanks of Bulgaria CITI GAS. The range consists of the storage volume in 2700, 4800 and 6400 liters of gas. Gazgoltery of the two companies is not only the volume but also the color of the tanks and brand marks on them.
Bulgarians dye their gas tanks in blue, is applied to them CITI GAS label and volume. Italian tanks have a green color
The cost of vertical tanks is higher than that of horizontal samples. They effectively serves gas mixture in the temperature range -40 - + 40⁰. Their service life is 30 years.
Horizontal tanks for gas
Horizontal gas tanks compared with the vertical more productive. There is one caveat - the rate is unstable. Once the level of the gas mixture will decrease to 1/3 volume, it starts to fall, so the system can operate stably without special reducer.
Horizontal vessel effective for heating the home area of 200 m² or more structures directly. To prepare the installation horizontal tank pit of small depth.
Its volume is necessary to take up 20% of the estimated fuel requirements. This is to ensure that there is enough gas to maintain the performance after reducing its volume to a critical value.
From a technical point of view gasholder it has a simple structure. In one of the process gases supplied holes and through the second fuel under pressure out of the heating system. To give the simplest use tanks with a capacity of 0.5 to 10 m. L
Metal housing gasholder withstand pressure above 1.8 MPa. Among the horizontal aggregates producers also leads the company Antonio Merloni.
On the market there, and units of the Czech company Deltagaz, Polish Chemet. The normal functioning of these reservoirs is possible even in unusual situations and in the most severe winters.
A detailed description of domestic gas tanks, Czech and Italian production shown here. We recommend you review useful information.
Properties filling gas tanks gas mixture
Periodicity refilling tanks of propane-butane is dependent on their size and on whether it is used so intensively. The average is 1 - 3 times a year. Importantly, do not miss the moment when the balance will be about 30%. Fill tank not brim and not more than 85%.
The supplier of the gas mixture must have a license and special transport. The easiest way to fill the gas tanks of mini mobile modifications to service cottages, as they can be transported on a trailer. Before filling the gas tank be sure to check the instrument performance.
