Every owner of a country house or cottage dream of spending your precious little house gas pipeline to secure year-round warmth and comfort.
But if you can imagine how much effort, work, patience, time and money it costs, even if - which the pipeline passes close, but your village is not connected.
More should be noted that by 2010 the price of natural gas to rise to the cost of liquefied natural gas.All this will lead you to seek an alternative - the installation of autonomous gas supply to heat your cottage.
liquefied gas or natural?
Recently, LPG has become popular as an alternative energy source.Many people think that the use of liquefied natural gas is much more expensive than natural, but it seems at first glance.If
thoroughly investigate the gas pipeline over a distance of 1 km.500 thousand. rub.except permission to connect that pull more than one hundred thousand. rub.Against this background, the use of autonomous gas supply LPG (a byproduct of oil and natural gas) to become rational.
LPG Advantages: independence from the central state of the pipeline, environmental friendliness, cleanliness and comfort.
Lifetime equipment for liquefied natural gas for 30 years.And after passing the prophylaxis and can serve longer.The cost of liquefied gas to diesel fuel Russian less, and the difference between gasoline and the gas is 40%.
wishes to purchase liquefied natural gas may implement this in two ways:
- based tank installations;
- on the basis of gas-cylinder units for individual use.
At low gas consumption of its best kept in bottles, because restrictions on the placement of small cylinders.
If you want to use group LPG storage you need to set them strictly according to instructions.The total capacity is 600 liters, they can stand in the third degree of fire resistance of buildings.Their installation is prohibited in residential areas and from the main facade.Near the apartment house can accommodate a maximum of 3 units balloon at a distance from each other at least 15 meters.
Cylinders and all equipment must be ventilated in a steel cabinet.As it should be provided valves, gas pressure regulator, pipes, high and low pressure, safety-relief valve and a pressure gauge showing.
analysis conducted by experts showed that independent gas supply with reservoir installation produce more savings than the use of gas cylinders.
But it must be taken into account:
- If the filling station (STS) to be close, the total cost of installing the gas supply to the reservoir will be higher than the cost for the use of compressed gas installations;
- If GNS is far away, it is better to use in the reservoir of gas.
for heating and water group homes or separate houses are increasingly using liquefied gas tank or gas tank.
To install it, you need space 4 × 1,3 m, and other than that you need to stretch the gas pipe to the boiler free standing or home.Gas consumption depends on the size of the size and type of vessel for a particular object.Practice shows that for heating the home area of 300 m² and for all the other household needs, the gas tank capacity of 4.6 cubic meters is enough for half a year.Gas tanks with a volume of 6 m³, suitable for boiler outputs of 50 kW - 100 kW.
gas tanks can be installed - under the ground and on the surface.Under the rules of ground gas tanks used in the presence of the evaporator.On the location of the gas tanks have a number of limitations.Reservoirs volume 5 m³ can be located no closer than 20 meters from residential buildings, 10 meters - from highways, 5 meters from the ground structures and communications, as if to establish a reservoir under the ground, the distance to similar facilities will be reduced by half.
According to the standards necessary to bury the tank below the soil freezing.But while valves must be available and present on the surface.From the tank should go wide neck to the ground.It is convenient that during the examination of the tank is enough to open the lid and specialist with their own equipment can get into the inside of the wall and to enlighten and seams.And in the absence of capacity will have to dig up the neck.
In accordance with SNIP in the installation must be at least two tanks, but for use in the private sector, allowed the installation of one gas tank
for a joint group of tanks they need to interconnect pipelines vapor phase, in which the device must be switched off (in the steam pipelinephase, which unites underground tanks, mandatory installation of disconnecting device between the groups of tanks, and its height must be above the ground not less than 0.5 m).
On the market there are a lot of Gazgoldernaya tanks.Reliable considered tanks polimerepoksidnym coating.Need elongated neck and non-removable flange through which you can perform repairs without digging tank.At the top of the gas tank for maintenance and refueling should guard with cover and lock.Additional tanks may be equipped with an evaporator and pumps liquefied gas.
Himself to install and connect the gas tank on the site is not permitted!Without permission experts liquefied gas will not be sold.It is better to consult specialists with extensive experience in the field of autonomous gasification and all the problems associated with the processing of all kinds of papers and permits will fall from your shoulders.
They will help you design a system to your needs, will make the supply of equipment, installation, registration of Rostekhnadzor of the Russian Federation, will produce liquefied natural gas refueling.And will continue to provide warranty service to you during the operation.
