Autonomous gasification of a summer residence

The lucky owners of suburban cottages and summer cottages can tell you about the feasibility of arranging a gas supply system like no other: the benefits of civilization are especially valuable when inaccessible. You can heat wood or try to warm the house with electricity. Both that and another are rather expensive, the first is also laborious. The most economical option for energy supply was and is gasification. Unfortunately, it is not always possible to connect to the main gas supply. The subject of close consideration today will be autonomous gasification of a summer house with liquefied gas. Consider the disadvantages and advantages of the arrangement, as well as possible difficulties during installation and operation.

Advantages and disadvantages of autonomous gasification

For the operation of a gas stove alone, it is not necessary to equip a gas supply system, as you understand, just connecting a cylinder with liquefied gas. Autonomous gasification is necessary for a comprehensive solution to the problems of heating a house in winter and hot water all year round.

General scheme of the autonomous gasification system

The general scheme of the device autonomous system of gasification of the cottage clearly shows the possibility of providing a fully non-volatile system

Liquefied gas can be powered by an electric generator, but the creation of a backup source of energy supply, and even in conditions of frequent power fluctuations, will not be out of place! Thus, the gasification of the cottage, in addition to the obvious advantages, is valuable in that it will help make the house completely non-volatile. Among the advantages of an autonomous gas supply of a summer residence are the possibility of an uninterrupted supply of fuel to the consumer, ease of operation, environmental friendliness, and, importantly, economy.

The device of the autonomous gas supply system

The gas supply system consists of a tank (gas holder) filled with a propane-butane mixture, shutoff valves, devices for automatically adjusting the pressure of the gaseous phase of the fuel, as well as a gas pipeline connecting the tank with gas consumers.

Gas holders come in various sizes and allow you to save enough gas reserves sufficient for the operation of an autonomous home system throughout the entire heating period. The gas holder can be installed on the ground or buried in the ground.

Overhead placement of the gas tank

Overhead placement of the gas tank is used in warm climatic zones. The container is painted white to reduce heat in the sun

When choosing an installation method, it is important to consider the climate. Low temperatures in the winter period prevent the transition of gas from the liquid fraction to the gaseous one, which may cause its lack for consumers. Therefore, an overhead installation is more often used in areas with a warm climate, and in areas with a harsh winter, underground placement of a gas tank is more appropriate, the soil provides the necessary temperature level. When underground and above-ground placement of the gas tank, it is important to consider the need for corrosion protection. The tank standing on the surface is painted, intended for underground installation, coated with special resins and anti-corrosion polymer compounds.

Underground installation method

The underground installation method is safer, during the arrangement a small area of ​​the personal plot will be occupied

Possible difficulties in operation and methods for resolving them

Liquefied gas, in fact, is an explosive substance, with increasing temperature (for example, in summer) it expands significantly, the volume of liquid increases, which leads to a general increase in pressure in the tank. The container may be depressurized, simply saying burst from internal pressure. To avoid this scenario, it is strictly forbidden to fill the gas tank with liquefied gas by more than 85% of the volume.

Another likely difficulty in operating autonomous gas supply systems is to ensure the safe operation of the gas pipeline and all systems. Even a minor leak from a gas pipeline can be extremely dangerous. Gas is about two times heavier than air, so it “flows” to the lowest sections, accumulating in basements and basements, then, mixed with air, it forms an explosive explosive mixture. Therefore, the correct arrangement of the boiler room is extremely important. All radiators must be above ground level. Good ventilation (natural) is another prerequisite. Be sure to regularly check joints for leaks. The room where the gas consuming devices are located must be equipped with gas detectors.

The neck of the tank

The neck of the tank, it is used for refueling and access to pressure control devices

Among the main advantages of an autonomous gasification system device it should be noted the possibility of energy supply in automatic mode, a minimum of control by the user, economic feasibility and high performance. The main condition for effective work is a responsible attitude to the issues of arrangement, because gas is explosive, carelessness at any stage of installation and operation of the system is unacceptable. Each installation using liquefied gas must be registered with the relevant authorities, all installation, installation, and refueling activities must be carried out only by qualified specialists (with the appropriate license).
