decision on the gas feeding to the private home reasonably sound economic considerations, as this is the cheapest, and therefore the most demanded type of fuel.Those who wish to implement the project of gasification, be aware that a mandatory step towards the goal of designing the gas supply will be needed to ensure safe operation and to connect the stand-alone residential facility to the centralized networks or autonomous gas tanks.The right to perform design works on creation of gas supply systems owned by only licensed firms performers.However, the customer will not prevent information about design rules for monitoring and to select a rational scheme.

What you need to consider when designing?↑

This type of fuel is classified as flammable hazardous substances.The slightest deviation from the dictates of construction standards c

an end in tragedy.Moreover, the gas is toxic and dangerous to the environment.All these nuances must consider designer.The home owner should know that it is best to order the project during the construction of the house, as the gas heating device is necessary to allocate a special room under the boiler room, ensure adequate ventilation and totally secure use.

Design of gas supply must be left to professionals
Design gas supply must comply with professional designers, as transportable and recycle boiler substance is classified as inflammable and explosive

specifics of creating gasification projects ↑

Previously called the cost of the final result can not even design.Depends on the amount of the weight of criteria, including the principle of the wiring width of the pipes, the number of steps of the fuel pressure, the number of bends, selected materials and equipment.Definitely need to pay for the design of gas supply systems, including:

  • project creation liner from centralized fossil fuel pipeline to the house;
  • development of the project for the internal wiring of the gas network.
Designing of systems of gas supply
design of gas supply systems for private homes includes the establishment of Project liner fuel the building and drafting of internal wiring

will also need to pay for the installation, designed for the installation of the pipe assemblies, fittings.

types of outdoor pipelines ↑

Get inducting gas into the home network in two ways.Piping is underground or without costly excavation, paving it openly.

  • construction of underground gas pipeline will cost about 1.5 times more than the laying of overhead way.However, the pipe will be much better protected from external mechanical and atmospheric negative.Underground systems are much more reliable and safer, but in the case of damage to find and eliminate the cause will be complicated and expensive.
Underground gas tank installation for the organization of autonomous gas supply
underground method of laying the gas network more expensive, but the security is far ahead of the device structures for the fuel above ground
  • Construction overground network is cheaper, but the open part of the pipeline will threaten the corrosion them easier to illegally connect themDangerous for the environment.
Natural private house: open padded pipeline
Paved open way pipe corrosion, it is easier for them to connect without the consent of the owners

not always preferences in choosing the Skytrain or the opposite way to influence only the price factors.Do not depend on the desire of customers conditions is:

  • inappropriate requirements of GOST values ​​of soil corrosivity, excluding underground installation;
  • proximity of high-voltage transmission lines, because of which will have to choose the construction of an underground pipeline input;
  • absence of the consent of neighbors, if part of the underground pipeline would cross their land;
  • recorded in the region of atmospheric temperature is lower than - 45º, due to which the pipe lay will be possible only under the earth;
  • the intersection of major highways, restore the integrity of which can not be classified as cheap activities to the same period in the installation do not even too "busy" road will need to be cut off to give permission to transport and inspection services.

often project pipeline liner to the house is a combined version that combines both methods of laying.What the designer chooses, it depends on the circumstances and the exact characteristics of the site.

specifics of the design of internal networks ↑

calculation and design of the gas supply of private homes is based again on a purely individual factors on which the boiler is chosen and a certain type of power, additional equipment, designed circuit wiring.However, there are common for all the projects requirements, compliance with which is a prerequisite for gasification.

  • Mandatory presence of a gas boiler for installation of the unit, as its placement is prohibited in residential areas.On the one pot should be given a minimum of 4 m² in the room with a ceiling height of at least 2.2m.Doorway combustion should be 0.8 m wide, possible.The size of the windows is calculated from relying on the 10 cubic meters of space 0.3 m. Combustion must be finished with non-combustible materials.
Have the boiler room - a prerequisite organization of gas supply
Prerequisite gasification - the presence of the furnace (boiler), equipped according to the strict regulations of the safety requirements
  • in the boiler must be carried out mains, sewer, gas and water pipes are laid.For the safety of electrical communications need to be grounded.Water is supplied to the device heating and hot water supply, drainage is needed to provide emergency drainage.The gas pipe should have a separate shut-off unit for each of the boilers.
Design of gas boiler-house to be finished with non-combustible materials
in the boiler room should be all communications necessary for the connection and functionality of boiler equipment
  • furnace room should have access to the general ventilation system of the building and two additional channels for the chimney.One of the additional channels intended for the installation of the chimney, the second - to clean it.For units with a natural chimney require ventilation grille, through which fresh air would come from the street.
  • flue should be made of a gas-tight material.The upper plane of the slice of the chimney above the roof is installed.Height of the protruding portion of the tube above the roof depends on the flammability of the roofing material.

Natural gas supply design for private homes: the rules of the device of exhaust gas - the height of the chimney
  • main system unit - the boiler is located away from creating a threat to open fire.From all sides it should be provided free approach.

by natural draft is not necessary to do, if the boiler is able to forcibly remove the products of combustion that made built-in pipe above the roof ridge ventilator.Typically, this double, so-called coaxial chimneys, comprising two pipes with different diameters.Through an external annular channel coaxial chimney to the room air flow from the street, while warming up by the thermal energy of flue gases to the outdoors.This design helps to reduce fuel consumption by increasing the efficiency of the gas unit.

Designing of networks gas country houses: rules installation of boilers
Terms installation of boilers:
A. From the boiler to the surface unprotected ceiling distance of 1.2 m from the side of the plane of the wall exposed to 0.32 m to the wall with metal sheet on asbestos board distance can be of 0.26 mmore.
B. From the chimney to combustible construction distance of at least 0.5 m if the walls are lined with a metal sheet on asbestos, the boiler can be installed at a distance of 0.25 cm.

course, installation of transporting explosive toxic substance asnetwork design of gas supply must be left to professionals.Risk amateurish mistakes too large and catastrophic.However, knowing the intricacies of the organization gasification identify errors fraud artists will be much easier and timely elimination of shortcomings provide impeccable service.
