Is such independence good: features of an autonomous gas heating system

When installing an autonomous heating system with liquefied gas, it is important to know what are the requirements for the installation process and to the equipment itself. It is also necessary to make the calculations correctly.

Why develop a project for autonomous gas heating

A drawing of the autonomous heating system design will be required to obtain official permission from the relevant authorities to carry out installation and to confirm its legality.

When drawing up a diagram, the following is taken into account:

• area of ​​the heated room;
• climatic features of the region;
• number of windows, doors;
• Thermal insulation characteristics of the house.

A visual diagram of the boiler layout and components is developed from different angles.

If you don't have experience in creating such documentation, it's worth seek help from specialists, who will independently carry out all calculations and make a cost estimate.

Only after receiving official approval from government agencies do they begin purchasing devices and installing them.

Heating system design

Autonomous gas heating means installation of a boiler of suitable capacity.

The most durable are considered to be floor products. But due to their large dimensions, it is better to place them in a separate room. In addition to the boiler, the heating system also contains other elements.

Gas holder

It is a cistern-shaped reservoir made of anti-corrosion metal. The inside of the gas tank is filled with a propane-butane mixture (liquefied gas). The tank is positioned so that the minimum distance from the house is 10 m, from engineering communications - 2 m.

There is a gas holder horizontal or vertical. The second type of devices is installed less frequently, only if there is not enough space on the site. In terms of price, such a design will be more expensive. Of the components, you will have to buy a liquid phase evaporator to avoid freezing of the tank and stopping the fuel supply to the house in severe frosts.

In regions with a mild climate They purchase a gas tank with a short neck and mount it on the ground surface, having first completed thermal insulation work.

Photo 1. A horizontal gas tank in the form of a tank with a short neck is usually mounted on the ground surface.

A more popular option is – high neck tank. It is installed underground, below the soil freezing level.

Fuel is supplied to the boiler via a mini-gas pipeline. The consumption of propane-butane mixture depends on the heated area and the intensity of equipment use.

For heating 250 m² a country house will need a boiler with a capacity of 25 kW, the volume of the gas tank in this case is 5 m³.

For autonomous gas heating, the optimal tank volume is from 3 to 10 m³.

Filling the tank 1-2 times a yearIt is important to take into account that the lowest prices on propane-butane mixture at the beginning of the year and in April.

Other elements

Besides the gas tank, for the full operation of the system Other details also contribute to the heating:

• radiators;
• pipes;
• shut-off valves;
• automation devices.

The first three elements pass through the entire house, so you shouldn't skimp on them. It is recommended to give preference to compact products so that they don't take up much space in the room.

Thanks to the last detail, the heating system works without interruptionOwners independently regulate the indicators using the corresponding buttons and sensors.

Automation allows for control over:

• indoor temperature;
• pressure;
• liquefied gas consumption.

Installation of a boiler in a private country house

When choosing a place to install a heating device, consider the following nuances:

1. It is not recommended to install the boiler in the basement., since it is more difficult to extract from there.
2. The minimum area of ​​the room for installing the structure is 15 m³.
3. If the boiler capacity is up to 60 kW, it is placed in any room of the house, including the kitchen. When the indicator over 150 kW A separate room is allocated for the device.
4. The recommended ceiling height in the boiler room is 2.5 m.
5. Ventilation is done in the lower part of the room., because propane is heavier than air and will accumulate above the floor.
6. It is desirable that the boiler room have a window, a separate door to the street for sufficient air exchange.

Installation of an individual gas device

Self-assembly of gas tank parts and other components by inexperienced specialists will lead to to inefficient heating of a country house or to a gas leak. The guarantee of correct adjustment of the individual gas heating system is installation by professionals.

The procedure for installing a gas tank is as follows:

1. 

   A pit is being dug using special equipment. Its depth depends on the volume of the reservoir and the climatic features of the region.
2. A concrete slab is laid on the resulting area. It will protect the gas tank: if the groundwater level rises, it will not allow the tank to float up.
3. A trench is dug at an angle from the house to the cistern. It contains a polyethylene pipe through which fuel will be supplied.
4. A condensate collector is installed at the lowest point.
5. The gas pipeline and gas tank are covered with a layer of sand and soil so that the neck of the container is visible from the ground.
6. Shut-off valves, control devices, and a reducer are attached to the tank neck.

Benefits of choosing

By giving preference to the autonomous heating system with liquefied gas, the consumer reduces utility costs, receives a set of automated equipment.
