My home is my castle. This old and hackneyed truth is familiar to many. This is the ideal that every living creature on the planet strives for. But apart from the fortress itself, home is comfort. For everyone, this means something different. But it is easy to agree that a person is more comfortable in warmth and satiety. The ability to warm your home and cook food gives energy. The most common sources in Russia are electricity, solid fuels and gas. We will talk about one of the ways to ensure the last from the list. The editors of the site "bestx.htgetrid.com/en/" have compiled a rating of gas tanks.

Gas to every house
First of all, it is the most profitable method of heating a private house. Secondly, it is not only fuel for the heating boiler, but also for cooking, as well as automobile fuel. But it is far from always possible to connect to the gas main. Yes, and ordinary gas cylinders, especially if you need to heat 150-200 square meters, you will need a lot. In this case, the homeowner will be rescued by a gas tank - a tank for storing gas in liquid form.
Gas tank variations
There are many differences between these tanks. From material to destination. We will analyze which ones are in structure, position, application area and functionality, giving their approximate and free classification, starting from their configurations. This will help us understand how to choose the perfect tank for the conditions of your site.
By position in space
| Position in space | Features: |
|---|---|
| Vertical | The evaporation area is several times smaller than that of horizontal ones. Often, in the climate of Russia, in addition to the gas tank itself, additional equipment, such as an evaporator, will be required. |
| Horizontal | Large evaporation area. Additional equipment is only required when operating in extreme cold conditions. |
By placement method
| Placement method | Features: |
|---|---|
| Overground | More stringent placement requirements. At negative temperatures, the gas ceases to evaporate on its own. |
| Underground | Reduction of fire and explosion hazard. Does not occupy an area on the land. In winter, no installation of an evaporator, pump, heating and insulation is required (the colder the climate, the less this statement is true). |
| Requires additional land work when installing systems. Repair becomes more complicated. Additional requirements for corrosion protection and safety factor of the tank. |
If possible transportation
| A type | Feature |
|---|---|
| Mobile | Small volume (usually up to 600 liters). Manufactured as a trailer for a car. |
| Stationary | No easy transportation possible. Usually installed and fixed on a reinforced concrete slab or foundation base. |
By static volume
| Volume variability | Construction type |
|---|---|
| Variable volume | The pressure inside the tank does not differ significantly from the atmospheric pressure, and the volume decreases with consumption. |
| Constant volume | Rigid construction with walls up to 1.2 cm thick. Allows injection of gas under pressure. |
According to budget possibilities
The choice of equipment for the price rises quite sharply.Although gas is more profitable than solid fuel and electricity, the installation of a gas tank and its periphery is far from cheap. Even very budgetary ones will pay off only in a few years. But after, especially taking into account decades of operation, plus such a purchase will become very noticeable.
General functions of gas tanks
Actually, this is what they are made and installed for:
- For storing a stock of blue fuel;
- For gas distribution between consumption zones;
- Control of consumption rate and balance;
- Maintaining the working pressure in the tank.
Gas tank filling
In 2020, this is not a problem. For stationary systems, it is required to call a specialized transport, in the form of a tanker truck. It is worth checking the availability of permission for such activities from the gas supplier. The upload process can take up to an hour. Since the length of the gas supply hose is limited to 40 cm, it will be necessary to provide a road tanker drive directly to the gas tank. During operation, the tank must be grounded, locked in place, and the hose secured with steel clamps. The volume of injected liquid gas is determined by the meter. It is unacceptable to pump more than 85% of the gas tank volume. The rest is left to evaporate.
For the heating season, it is best to refuel gas in the fall, and, if possible, at the end of winter. At this time of year, the cost will be minimal. If the gasholder is mobile, then there is a possibility of self-injection at gas stations.
Tips and selection criteria
First of all, you need to determine what exactly the gas tank will be used for. It doesn't make much sense to install a 2,000 liter tank if the gas is used exclusively for cooking. For heating, however, it is necessary to determine the gas flow rate based on the heated area. Usually, tanks with a volume of up to 20,000 liters are installed for cottages. A larger volume makes sense for autonomous gas supply to several buildings or in industry, for example, for factory installations.
The size of the land plot also has its influence when choosing a tank for your country house. In a small area, it would be better to install a vertical gas tank, but this, in turn, may require additional installation of an evaporator.
The climate, especially if it is planned to use gas for heating a private house in winter, can literally drive the tank underground. Butane has a boiling point of -0.5 degrees, and for all standard gas systems it is needed in a gaseous state.
Gas tank in Russian realities
The climate of our homeland is making its own adjustments. Moreover, they are quite significant. If the installation of a ground vertical tank is suitable for a summer residence somewhere in the south of Russia, then in the area of Moscow and, moreover, St. Petersburg, it is better to think about an underground installation. In turn, this means that a gas tank with high nozzles or a neck is needed so that melt spring water does not get into critical systems, and the gas itself is below the level of soil freezing. The walls of the tank must be able to withstand seasonal soil movements. The anti-corrosive shell must withstand possible floods and high groundwater levels.
Another thing worth paying attention to is the operation of systems in the cold when laying a pipe in the open air or at a depth of freezing of the soil - liquefied butane. Condensed on the walls of supercooled pipes, it can cause blockages. After that, you will have to urgently blow the entire gas pipeline. To avoid such troubles, it is necessary to install a condensate trap. It will collect droplets of liquefied gas, which will evaporate back with the arrival of heat.
Rating of the best gas tanks
For you, we have prepared an overview of the best gas tanks for 2020. But due to the nature of the equipment, these are not specific popular models, but in fact a comparison of the best manufacturers. This was done because there are no recommendations as such on the volume, but the characteristics are considered, basically, of the entire model range.In this rating of high-quality liquefied gas storage tanks, we will consider both foreign-made and domestic devices.
FAS
Joint production of Germany and Russia FasHimMash. They produce tanks of the day of aboveground and underground installation, vertical and horizontal variations. The body of the product is made of steel grade 09G2S-12, more than 6 mm thick. Anti-corrosion protection is represented by an epoxy film corresponding to the requirements of GOST 9.602-2016, which belongs to the "Very Reinforced" type. A special plus for Russia is the neck, 80 cm high, which allows the equipment to be used in more severe climatic conditions.
All tanks undergo hydraulic and pneumatic tests. Operating temperature from -40 to +40 with operating pressure up to 1.5 MPa. The estimated service life of 35 years has not yet been confirmed. production is not yet 15 years old.
Factory-set FAS gas tanks have economy-class American-made fittings, flanges and valves will have to be systematically tightened, and the protection on them is extremely weak, of those that are generally installed.
The cost of a gas tank with a volume of 2700 liters and high nozzles (65 cm) is 117,000, for 25,000 liters it can reach 950,000, depending on the configuration.

Disadvantages:
- We saved on the outer coating by taking materials with medium corrosion protection values;
- Poor quality of reinforcement;
- Not suitable for regions with severe frost - additional thermal insulation is required.
Bear
Russian-made gas tanks manufactured in accordance with GOST R 52630-2012 and PB 03-584-03. Horizontal, aboveground, underground and mobile structures are manufactured. The body is made of steel grade 09G2S with a thickness of more than 5 mm on the walls and 6 mm on the bottom and coated with a two-component INTERZONE epoxy compound.
The quality of the anti-corrosion coating is ensured by preliminary shot-blasting of metal and application of protection by airless method. Stop valves and reducers of the Italian company CAVAGNA. The quality of incoming materials and outgoing products is controlled by an internal laboratory complex. Defects are diagnosed using ultrasound, indicator liquid, visually, radiography and magnetic particle flaw detection.
The strength of the equipment itself and its elements are made taking into account the peculiarities of operation on the territory of Russia. Although the warranty is given for 35 years, the declared estimated service life of the tank is around 50 years, which separately justifies the popularity of the models of this manufacturer.

The agony of choice
It's up to you to decide which company is better to buy equipment for your house, cottage or country estate.
As a warning, I would like to remind you that saving from the purchase and installation of a tank from the "sharash-mounting system" will bring joy until the first flaw found. And at best, the desire to buy an inexpensive device and installation services will result in just additional expenses. At worst, choosing mistakes will cost lives. Just remember what happens when household cylinders explode. But they contain only a few tens of liters.
