Currently, the issue of gasification of a country house has acquired particular relevance. The main reason for this is both the rapidly developing construction of the private sector in the suburban area and the laying of gas mains to the already equipped suburban areas and cottage townships. In the first case, the plan for gasification of housing and auxiliary buildings, as a rule, is included in the general construction plan. In the second, it requires the development of a special project, taking into account the individual landscape and architectural features of the existing structures. Both in the first and in the second case, the development of the project, the selection of the necessary equipment, its installation and connection is carried out by qualified specialists.

How to choose gas equipment

Gas boiler and radiators or convectors

When designing a gas heating system for a country house, the following factors must be taken into account:

• total area of heated premises;
• ceiling height;
• the degree of thermal insulation of walls and roof;
• internal layout of the house;
• wall thickness;
• exterior and interior finishes, wall and window decor.

You should also take into account how often power outages occur, and in the case of a country house, the need to heat it in the winter.

In the matter of choosing a gas boiler or convector heating, the opinions of experts boil down to the following: in the case of a sufficiently large area (over 100 sq. M.) Of a country house and permanent residence in it, it is necessary to install a gas boiler and radiators. Relatively oversized two-three-room country houses with seasonal visits are economically and efficiently heated with gas convectors.

In the first case, only an experienced specialist can develop a gasification project and select the necessary equipment.

In the second, you can independently decide on the choice of heating elements and their location, having agreed with the future performers of installation work on the project for installing gas equipment.

How to choose a gas convector

This type of heating device has received well-deserved recognition for a number of reasons, of which the most important are its energy independence, the absence of a freezing element, the efficiency of heating the room and ease of operation. When choosing a gas convector, you must be guided by the following parameters:

Fuel used

Most convectors offered for sale today are initially configured to operate on either natural gas (methane) or liquefied gas (propane). It is possible to transfer the device from main fuel consumption to bottled gas or vice versa, but this will require an additional set of nozzles, which can only be installed with a high degree of reliability by an experienced specialist.

power, kWt

The required power of a gas convector recommended by manufacturers is calculated as follows - 1 kW of power per 10 sq. m. area. Thus, to heat a room with an area of 20 sq. m. a 2 kW convector is required. However, it is necessary to take into account such characteristics of the building as the height of the ceilings, the thickness and level of thermal insulation of the walls and roof, the number of windows. With a room height higher than 3 m, a large number of windows or insufficient thermal insulation of the walls, an accurate calculation of the required power of a gas convector can only be done by a heating engineer.

Heat exchanger material

Most of the gas convectors on the domestic market are equipped with steel or cast iron heat exchangers. According to experts, with all other things being equal, cast iron burners should be preferred. The reason for this is the slight thermal expansion and the property of this material to accumulate heat, due to which a high durability and high thermal efficiency are achieved.

Flue pipe length

When buying a gas convector, you need to pay special attention to the length of the chimney pipe or, as it is also called, the flue. Some manufacturers produce models with short (35 cm or less) pipes, designed for "cardboard" country houses. Of course, there is always the opportunity to "build up" such a pipe in a tin workshop, but, nevertheless, it is better to initially decide on its desired dimensions.

Installation of the flue pipe - its length must correspond to the wall thickness

Fan presence

The main function of the fan built into the convector is to quickly generate heat in the room due to the accelerated air circulation. The expediency of installing a model equipped with a fan is determined individually and depends, first of all, on the regularity of using the convector during the heating season. In the case of a summer cottage, when it is often necessary to quickly heat up a cold house, the functionality of the fan is obvious. With permanent residence and regular use of the convector, additional noise effects created by the fan are completely unnecessary.

How to design a gas pipeline on your territory

The question of the method of laying gas pipes is solved in a complex way and depends on the following factors:

• remoteness of the building from the central gas pipeline;
• features of the landscape of the surrounding area - green spaces, reservoirs, asphalt paths, high-voltage power lines, residential buildings and public buildings;
• corrosive soil characteristics;
• the geometry of the building itself - the heights of arches, doorways, configuration of angles, symmetry or asymmetry of an integral architectural complex;
• own wishes of the owner of the territory and his financial capabilities.

There are three ways to connect to the central gas main.

Underground gas pipeline

The most expensive, aesthetically pleasing and most reliable solution. However, when choosing this method, which will cost more than one and a half times more expensive than its above-ground counterpart, one should take into account the laboriousness and significant cost of repairs in the event of an accident. In addition, high soil corrosiveness values can significantly reduce the service life and reliability of an underground gas pipeline.

Overhead gas pipeline

In this case, the pipes are fixed on separate supports made of non-combustible materials or attached to the walls of buildings with special brackets. At the same time, the distance between the supports should not exceed 2 m, the minimum distance to the ground surface should be less than 35 cm, and the functional purpose of buildings and the material of their outer cladding comply with the established standards.

Combined gas pipeline

Often, the optimal gasification solution is a combined line laying. The roadway or high-voltage power lines must be bypassed underground, while it is possible to save green spaces and not damage the fertile soil layer by laying pipes through the air.

The final decision in favor of this or that method of laying the gas main should be made only after consulting a qualified specialist.

How to organize the gasification process

There are two ways to solve this issue - step-by-step and complex.

In the first case, it is necessary to independently study the legal aspects, regulatory requirements and traffic plan for licensing and design organizations, collect all the mandatory documentation, conclude an agreement with the construction and installation team and the service that is engaged in tapping into the central gas pipeline, agree on the timing of commissioning with organization of service. Not everyone is able to find the time and opportunities for this kind of movement, which, moreover, will not in any way reduce the overall financial costs.

It is possible to solve the gasification issue much faster and more efficiently by entrusting one contractor to carry out complex organizational and technical work on a turnkey basis. From an economic point of view, this approach justifies itself both in the process of project implementation and in the course of the subsequent operation of gas equipment. This is due to a number of factors, which are discussed below.

Integrated gasification advantages:

• the contractor's interest in carrying out all gasification works as soon as possible;
• the contractor's interest in drawing up an engineering competent gas project that meets all regulatory requirements, which he himself will implement;
• established contacts of the contractor with trading construction companies, which allows him to purchase gas equipment at lower prices;
• long-term cooperation of the contractor with licensing and controlling structures makes it possible to timely and consistently carry out all gasification works.

Turnkey gasification pitfalls

When entrusting the gasification of a house on a turnkey basis to a specific organization, it is necessary to familiarize yourself with the list of documents that should be in the hands of its owner upon completion of all work. There are frequent cases when the contractor “forgets” to hand over the documents to the customer, without which further warranty service of gas equipment is impossible. In addition, the close acquaintance of the contractor with the representatives of the Gaza Mountains, who are part of the commission for accepting installation work, allows the latter to turn a blind eye to some shortcomings and regulatory deviations, which may subsequently result in additional costs for the customer. There is a widespread situation when, using the incompetence of the customer, the contractor convinces him of the need to install unnecessary or insufficiently optimal equipment in a particular case,thereby providing a mutually beneficial service to its trading partners. To protect yourself from unfair actions on the part of third parties, it is necessary to take special responsibility towards the choice of the contractor for the entire range of works.

Who to entrust complex work on gasification of a residential building

Construction and installation organizations that offer integrated gasification services must have licenses not only for technical, but also design work.

Before concluding an agreement, it is advisable to look at the object already gasified by this organization, to talk with its owners.

Clearly stipulate the timing of the work and carefully study the sketch of the project - "growing" the heating system will cost much more than the planned installation.

Consider the presented estimate of gasification works. At the same time, conversations about "unforeseen expenses" often do not testify in favor of the contractor.

Make sure that the general plan includes minor cosmetic work - painting pipes, filling holes, removing construction waste.

Having decided on the choice of a construction and installation organization, conclude an appropriate agreement providing for penalties in case of violation of the conditions for its implementation.

The rational organization of the gasification process of a country house and a competent approach to the choice of equipment that is optimal in each specific case allow the most efficient and cost-effective implementation of a project of any complexity.
