It is very important to know how to insulate a gas cylinder on the street, and do it in winter to avoid condensation. It is the condensate winter period brings a lot of trouble to the owners of gas cylinders that are on the street. But for proper insulation, you should pay attention to the special points that are disclosed below.

Tank insulation option

Each cylinder in operation requires special attention and meticulous care. After all, it is constantly influenced by external factors. This is especially true for private houses, where such a source of gas is often an indispensable part of heating system, but it is installed outside the house.

Why is insulation necessary?

Before insulating a gas cylinder on the street in winter, it is necessary to establish exactly why this is necessary. main reason- this is to prevent the gas cylinder from freezing in the cold season, so that it provides efficient heating. It is also necessary to ensure the full removal of combustion waste. They are created during the operation of the heating system device.

This is what an insulated balloon looks like

In addition, working with an insulated cylinder allows you to naturally increase the efficiency. And the type of fuel does not matter. When the heated gases pass through the pipe, they give off heat to the walls. The draft will depend on the rate of heating of the chimney walls. If there is a drop in draft, the smoke may return back into the house, creating smoke, in which case the residents of the house are in danger.

Also, the traction force directly depends on the amount of time that is necessary to prevent the occurrence of condensate. In other words, this is the time it takes to preheat the static flue duct. For example, brick chimney with insulation on average shows from 20 to 35 minutes. But the same, but made of steel, only 2 - 5 minutes.

It is worth being prepared for different temperature cylinder and air will still create condensate on the pipe. After all, a warm balloon is always on the street, where the air is cold. But reducing the appearance of condensate to a minimum is quite real. You just need to make proper insulation balloon.

Important: when condensate appears, the following process occurs: water is mixed with the released carbon dioxide. The result is a fairly strong solution with high acidity. Acid eventually damages the chimney.

What to pay attention to

The main reasons for the need for mandatory insulation:

  • after warming, the balloon will not be covered with frost and precipitation will not annoy him;
  • heat loss will be minimized if the chimney is properly insulated;
  • the outer side of the pipe will be free from large condensate (its amount will be minimal);
  • your dacha will be more attractive, since the balloon, which by itself looks out of place in the yard, will be hidden in a neat design.

This all speaks of how important the insulation of a gas cylinder is, and what advantages it will provide for heating in the future.

Materials for insulation

Choice the right materials for the task at hand is a very important question. After all, do not forget that safety equipment should always be on top. So what should be taken into account operating conditions. Properly organized insulation will be a reliable protection for many years.

Insulation cabinet option

The most popular materials are:

  • lukewarm various types(mineral wool);
  • slabs of basalt;
  • glass wool;
  • brick of red or rubble refractory type;
  • galvanized sheet metal.

Why exactly them? The fact is that all these materials have excellent fire resistance. In addition, they have a long operating period and are neutral to chemical environment. The advantage can also be considered that it is easy to work with them without resorting to special tools. In addition, the price is more than acceptable for everyone.

Wooden cabinet for insulation

The flexibility of each of these materials allows them to be used as practical as possible, even with the most complex designs. different forms. The balloon is securely covered around the perimeter.

Important: if you use mineral wool, do not forget about the mandatory use special means personal protection.

Glass wool is very dangerous if used incorrectly. To choose the right material for insulation, you need to start from the materials that were used to build the chimney.

Insulation options

Of all the options, the most difficult is the insulation of a brick chimney. There are several main insulation options for this. They can be applied to different materials.

  1. Application of plaster for insulation. First, a special solution is created. It should be laid in a layer on a pipe with a thickness of at least 4 cm. Experts recommend making 5 to 7 layers of plaster. No frost will cause problems anymore.
  2. The use of special asbestos-cement or basalt mineral-cotton slabs. The thickness of the slab should be about 5-6 cm. The fastening is formed from a mixture for cladding. A reinforcing mesh should be placed on top of the insulation. Then you can apply plaster.
  3. Wooden shields are the most simple option for isolation. The work is carried out in several stages. First, a special wood frame is formed around the entire perimeter of the chimney. Can be used as a material wooden beam. Do not forget about the gaps between the materials (about 15 cm). Next, the frame must be sheathed with slate (flat). All gaps should be filled with slag or sand. In the process of filling, you need to tamp the material. Using profiled sheets, you need to arrange a decorative layer of insulation. Fastening elements in the places of fixation - roofing screws.
  4. Wood insulation.

Decorative box option

Regardless of the chosen insulation option and the insulation material itself, the heat savings in the house increase by at least a quarter.

Heat in the house is a very important indicator. Knowing how to insulate a gas cylinder outside in winter, you will not only protect the gas cylinder, but also significantly increase the efficiency of the heating system of the whole house for many years to come. The main thing is to choose the right insulation materials and organize professional installation. And even more important points You can find out by watching the video.

This is a longstanding problem in high-altitude mountaineering.
Previously, they went with Bumblebee gas stoves (a Soviet copy of the Austrian Phoebus), and with proper maintenance they did not know grief.
Then newfangled gas burners with cartridges appeared and the problem of gas freezing rose to its full height.
The gas is consumed, expands, and, in full accordance with the laws of physics, cools down to freezing.
Even at not very low temperatures, I had to warm the can with my hands, I beg your pardon, on the eggs (the warmest place), and I had to pervert with a candle.
Until someone brought a newfangled bourgeois device from over the hillock - a heat pipe.
The silumin piece with a built-in magnet repeats the shape of the shell of the side wall of the can and is tightly magnetized to it. A steel rod is pressed into it, top part which touches the flame of the burner.
Accordingly, during the cooking process, it (the end!) Heats up, heat is transferred through the rod to the silumin-magnetic part, and it, in turn, heats the side of the can.
This device works, be healthy!
It's easy to repeat it.

Hello dear readers. Did you know that a heater for a gas cylinder is simply necessary in cold weather. And what can happen if the balloon freezes. How to prevent this and how to warm it up?

The situation on the street

Warming a gas cylinder in winter is a particularly sensitive issue. It is very relevant for fishermen and tourists. He also worries the owners of private houses and buildings, the cylinders of which are on the street.

It is also important here at what temperature propane gas freezes in cylinders. Already at -15, the liquid substance in the cylinder freezes. Gas production slows down. And the operation of gas appliances is disrupted. For example, when hiking or fishing, there may be problems with burners, fixed annuity interest rate in the country - with a portable stove.

At -30 there is no gas production at all.

And the next question arises - is it possible to heat the propane cylinder so that gas units work better. Play and earn money liquefied gas contains a pair of hydrocarbons: propane and butane. Evaporation of the former occurs at extremely low temperatures. Evaporation of the second - already from -14-15 degrees.

In order for the cylinder to function well in winter, the composition should be about 70% propane.

It is possible to heat the cylinder, but within the permissible limits.

How to insulate a gas cylinder on the street? How to warm a gas cylinder on the street? These sensitive questions are different solutions. The following are some popular methods:

  1. The use of disposable chemical heating pads. They heat up to 35-40 °C. This is the maximum allowable rate for cylinders. The duration of the operation of such heaters is 6-7 hours.
  2. Use of reusable salt pads. But their norm is about 50 ° C. It is somewhat dangerous to heat the cylinder with them.

In principle, the gas cylinder heater can be anything. The main thing is that its functional temperature does not exceed that of the cylinder. This rate is displayed on the label. The balloon needs constant monitoring. financial assistance grants It should be probed periodically. If it is a little warm, you need to reduce the thermal effect on it. If it gets too hot, immediately stop heating it.

Often, at dachas, the owners place the cylinders in special devices, these can be boxes, lockers, etc. And here a logical question arises - how to insulate such a cabinet for gas cylinders?

Here is the most effective method– apply the BH Thermal system. It costs between 7000-8000 rubles. You can use the domestic analogue of TEO-GB1 for about 5000 rubles. This is a lightweight non-flammable stocking that provides heating. It completely covers the surface.

How to warm up a gas cylinder when it freezes? If your gas cylinder is freezing up, then you need to apply any of the following actions (or all):

  1. Smoothly pour over the balloon hot water. You can act on it with hot steam. The cylinder valve is closed. This is partial heating. In order for the payday loans gallatin tn part to warm up completely, it must be removed, transferred to a warm room for 20-40 minutes. In no case should heating be carried out with an open flame.

After the procedure, the moisture concentrated there is removed from the gearbox by blowing. Before purging, its hose is removed.

  1. Transfer the entire container to a warm room. This must be done immediately when the gas cylinder is covered with frost. The cylinder must be kept indoors, preferably near the battery, until it warms up. You can connect a special electric heater.
  2. Apply saline or chemical heating pad. That is, hiking methods of heating.

By applying these methods, you will solve the dilemmas of what to do if the gas in the cylinder is frozen, if the cylinder is frozen, etc.

And in order to avoid such troubles, the cylinders need to be concentrated in warm rooms or heated with high quality.

In the first case, a heated floor technology should be installed under the cylinders on the basis of the existing heating system.

In the second - to use efficient heaters.

  1. Management will improve significantly.
  2. Reduced consumption of liquefied gas
  3. Pressure develops inside the balloon - this is a consequence of the formation of convection heat.
  4. A pure liquefied fraction will be produced. So gas is saved up to 30%.

Question with HBO in winter

What problems can there be with HBO in winter? If the gas-balloon equipment is installed correctly and is serviced in a timely manner, then the difficulties with the operation of vehicles with LPG in winter time does not occur.

And the reasons for the difficulties may be incorrect installation or low-quality fuel. Usually in winter in liquefied gas they develop a proportion of propane up to 80%. Reason: It evaporates remarkably. If summer gas is poured into the car, its evaporation will not occur, pmi 2013 the car will run on gasoline.

In winter, liquefied gas is consumed more intensively, because the percentage of less dense propane is greater than the percentage of butane. The driver is forced to press harder on the gas.

The greatest difficulty for HBO in cold weather is gas condensate. These are oily substances that remain in the gas after its poor-quality purification. When it is liquefied, these substances are dissolved in it. They freely penetrate into the reducer-evaporator, having passed the filter. In the cash advance businesses reducer, the propane-butane composition is affected by temperature, and it is converted into gas. And the substance does not evaporate and can get into the reducer and nozzles.

Why freezes gas reducer? The most common cause lies in the indicated oily substance. Gearboxes that have direct control over the dosing valve (multi-valve) are most often affected. As a result, the HBO multivalve, the gearbox itself, and other parts freeze.

When this contamination penetrates into the space between this valve and the master cylinder, the valve becomes stationary, the gearbox does not provide the right pressure, the gas does not flow well to the nozzles.

If your car has such parts, refuel only at reliable gas stations.

Oily condensate also harms the injectors. Their petal versions, which are spring-loaded by a metal membrane, suffer the most. They just stick to the electromagnet. The gas is not dosed out the intake manifold. As a result, it is spent more, the nozzles break.

Modern versions of injectors have a pin electromagnetic gas valve(EGC). They are less susceptible to low-quality fuel. But in the cold, oily mixtures do not crystallize, they become sticky. Because of them, the nozzle valve is not paralyzed. As a result, the engine may stall.

Question with cylinders in cars

Why does the gas cylinder on the car freeze? Firstly, this means that the gearbox freezes. The reasons for its freezing are as follows:

  • in the cooling technology, the content of a special liquid - antifreeze, has decreased,
  • wrong hoses,
  • water pump problems
  • the thermostat is malfunctioning,
  • difficulties with EGC,
  • gear diaphragm broken
  • condensate has entered the gearbox,
  • gas leak.

When there is little antifreeze, air jams appear.

When hoses are not properly sized, they may become clogged or missized. In this case, the circulation of antifreeze stops, and the gearbox freezes.

When the water pump is faulty, this is also a sign of impaired circulation of a special fluid. When the pump is not working, the cooling system is interrupted. The result - the gearbox freezes.

If the thermostat is not working properly, the following symptoms may appear:

  • engine overheats,
  • the engine takes too long to warm up,
  • antifreeze gets hot

If there are difficulties with the EGC, the power contact may break or the wire may oxidize.

If there are problems with the diaphragm (usually rubber), the gas is sent to the cooling system, frosting over the gearbox and some pipes of this system. The diaphragm needs to be replaced.

Gas leakage occurs due to leaky contacts. As a result, the gas supply pipe freezes over. Freezing occurs at the leak sites. Sign - there is a smell of gas. You need to open the hood and check all connections with soapy water.

When the gearbox rarely undergoes maintenance, and does not drain the condensate on time, the filters become clogged. It is necessary to arrange maintenance of the gearbox at least once a year.

Another very relevant question is at what temperature does gas freeze in a car?

Here the indicators are as follows: propane freezes at a parameter of -40 C, butane - 0 C.

And the composition of butane and propane usually freezes between the specified limits. Therefore, in winter, the composition contains more propane.

Conclusion

In order for the gas cylinder to work properly in winter, it must be efficiently heated.

Gas fuel has come into life reliably modern man. So, gas cylinder is a rather primitive device, but it also has a number of specific nuances. Next, you will be able to read about what gas cylinders are, but for now we will try to decide on the purpose of the gas itself.

There is an erroneous opinion that gas "locked" in a cylinder and gas in a pipeline are one and the same. The fact is that centralized gas supply uses methane, which is a natural gaseous substance, it is also called swamp. But gas cylinders are already filled with a mixture of propane and butane, which is also officially called SPBT. A mixture of propane-butovy technical is a by-product obtained during oil refining. In the future, he will use the wording SPBT or simply “gas” for it.

Propane-butane mixture is absolutely universal. It is widely used in the petrochemical industry for the manufacture of polymers, as well as mechanical engineering and metalworking - for welding and cutting. metal surfaces. In addition, SPBT can act as a gas engine fuel.

Complete diagram of connecting a gas cylinder to a stove

In everyday life, such a gas mixture is used to sell autonomous gasification Housing and communal services. It refuels gas tanks and various gas cylinders in which gas is burned by the forces of domestic boilers, stoves and other household appliances. gas equipment. Carbon dioxide and water act as combustion products, for this reason such combustion is considered as safe as possible for the ecology of living space.

In cross section, a gas standard cylinder is similar to the design of a transparent gas lighter. The gas mixture in the liquefied state acts as a liquid, and free space above it is a steam cap that enters the boiler or stove. The balance between these media is maintained due to the pressure inside a special container.

Connecting the cylinder to consumption devices

The device must be connected via a reducer. Inside a conventional gas cylinder, the pressure is not constant and depends on the ambient temperature. It can vary from 4 to 6 atm. The reducer is able to lower and equalize the pressure to the optimum operating level of the cooker.

A hose is connected to the reducer, and a plate is connected to it. The place of fixation is fixed with clamps, after which it is necessary to check the tightness of the connection with soap suds. Any foam will do. The fixation points must be covered with soapy water: if bubbles form on the surface, then the connection is leaky.

We eliminate the leak: tighten the nut even more at the junction of the fitting with the gearbox. If a leak is found in the sleeve area, then tighten the clamps. After adjustment, it is necessary to check again with soap suds to finally make sure that there is no leakage. This test is always carried out when connecting gas cylinder- this is Golden Rule safe use.

Correct connection of gas cylinders on the street, figure 1

Correct connection of polymer-composite gas cylinders, figure 2

IMPORTANT! You should not act like some especially “experienced” gas masters: in no case do not check the tightness with lit paper. This results in small flames at the leaks. This is strictly prohibited by safety regulations. In addition, such flames are very small and in daylight can go unnoticed and lead to sad consequences.

Installation and operation of gas cylinders

The most important criterion safe operation such devices is to control possible leaks and overheating. Violation of sealing can be detected by a characteristic odor. The gas, in principle, has neither color nor smell, but a special marker is added to SPBT - a hydrocarbon-mercaptan. Due to this, a person can smell when the gas stove column is turned on or during a leak.

So, if you smell this smell, then we can conclude that the concentration of SPBT is 20 percent of the dangerous one. There is no reason to panic, that is, a reason to check the junction according to the above scheme.

Operation of gas cylinders, presented in the form of a table

When the gas cylinder is in the room itself, it should be placed at a distance of 1 meter from the stove, which in the active state is a heat source. Also, any other heating devices should not be placed nearby: heating radiators and autonomous heaters.

An acceptable option would be a "country" installation method - from the outer north side of the structure, which eliminates the possibility of overheating the balloon by the sun's rays. In such a situation, the sleeve must be passed through a hole in the wall, previously “treated” with a metal sleeve. The cylinder is placed in a special metal cabinet equipped with ventilation holes in the lower part of the walls. Since the gas is somewhat heavier than air, in the event of a leak, it will accumulate from below, where there will be ventilation holes, so a light wind can eliminate unwanted accumulation.

Why are the cylinders covered with frost?

Here you can also debunk one of the most common misconceptions. It is generally accepted that if such a device "freezes", then it becomes covered with frost. Some even argue that it is necessary to insulate such equipment with blankets, old coats and other improvised devices. So, the frost will disappear faster if the gas container is left as it is, without helping it to “thaw” with warm clothes.

The bottom of the gas cylinder, which is covered with frost

The appearance of frost can be explained by a number of physical processes that occur inside the structure when it is connected to furnaces or burners. At such moments, active fuel consumption is observed, therefore, large volumes of gaseous liquid turn into a vaporous fraction. And such a phenomenon is always accompanied by a large consumption of heat, it is for this reason that the surface of the cylinder becomes much colder than the temperature in the surrounding space. Moisture in the air space begins to appear in the form of condensate on the walls of the installation, subsequently turning into frost. This is a completely natural phenomenon, with which nothing needs to be done.

Moreover, all attempts to use artificial "insulation" violate safety standards during operation, and also affect the deterioration of heat exchange between the device and environment and affect the conditions of gas supply. If your burner did not please with a grandiose flame, then after your “maneuvers” with a blanket, it may stop working altogether.

Do not insulate gas cylinders with anything!

In general, when connected gas devices with high power, you need to be aware that the gas cylinder has restrictions on the speed of return. This means that the liquid fuel is converted into the steam stage gradually. For example, a 50 liter tank can provide about 500 grams of gas in 60 minutes. This is equivalent to a power of 6-7 kW. In the cold season, this figure is halved if the equipment is located outside. In summer, the situation is reversed: the maximum flow rate increases.

In any case, it can be concluded that frost is evidence that the cylinder cannot cope with high fuel consumption. This can cause a temporary drop in gas pressure and equipment failure. If this happens, it is better to stop consumption and wait until a sufficient head of steam has formed.

Why is there a "splash" of water in the container?

This can be heard in winter. Know that this is not water, but the butane component of SPBT. At the slightest frost, butane ceases to be converted into a vaporous fraction. It is she who "splashes" in the form of a liquid inside.

Butane component of SPBT in a gas cylinder

In the warm season, this problem does not arise: almost the entire propane-butane mixture is used. In order to avoid this in cold weather, it is recommended, when filling the tank, to ask the refueller about the availability of a passport for the used SPBT. This document must contain information that the mixture contains at least 80 percent propane, which passes from liquid to vapor during cold weather. If you use such a dressing, then there should be no problems.

How much gas is enough?

Here you can use primitive mathematical rules. If we start from the power of the stove, where 4 burners work at once, then 8 kWh of energy is used in 60 minutes. If you burn 1 kg of gas, you can get 12.8 kWh of energy. The first result must be divided by the second figure, resulting in the amount of "liquid" fuel necessary for the full operation of the stove for an hour. This figure is 0.625 kilograms of gas. Therefore, a 50 liter container with 21 kilograms of gas will be used to run the stove for 33.6 hours. If the power in kg of fuel burned is indicated in the passport of your equipment, then the calculations are greatly simplified.

In the future, everything depends on the intensity of use of the plate. If you often brew jellied meat, then the degree of consumption will be one, if you are content with only brewing morning coffee, then another. Based on practical experience, we can say that 12 liters of gas, which will be used by a small family on weekends in the country, will be enough for the whole summer. More detailed information about autonomous gasification you will find in this section.

How to fill a gas bottle?

Refuel such devices on the territory of special points, which can be located autonomously and enter the gas station. In the conditions of the latter, it is possible to refuel with gas motor fuel.

The most important nuance in this process is the fact that you need to refuel not by volume, but by weight. As a safety precaution, gas containers should be filled to a maximum of 85 percent of the total volume, in order to avoid excessive pressure.

In order to follow safety precautions and its standards, such a device with any volume is marked with a number with a maximum allowable weight, corresponding to the same allowable 85 percent. The tanks are placed on the scales, including fuel injection. The process stops after reaching the required weight.

But even when refueling relative to the mass, overflows are not excluded, which is especially important for small-volume containers - by 5 or 12. They should be refueled by 2 and 6 kilograms, respectively. The high speed of refueling sometimes does not allow you to see the achievement of the limit rate. If this happened to you, be sure to ask for the excess gas to be drained. In the future, it is better to choose another place for refueling.

In general, the basic criterion for choosing a tanker is the availability of license documents for the use of fire and explosive objects. If the documents are present, then we can conclude that you are served by qualified specialists who annually undergo special certification.

In other cases, you take responsibility for the operation of the refilled container. And you risk not only your money, but also the safety of your home and life. In addition, an unlicensed gas station is a violation of the law and may entail not only administrative, but also criminal liability regarding the article on illegal entrepreneurial activity.

The information provided in the review does not claim to be accurate encyclopedic data and is largely dictated by our experience. But we are sure that it can help you save a lot of time and money.

It is important to know how to insulate a gas cylinder on the street, heat it from condensate. What are the mandatory points in the insulation of chimneys. Why insulate them at all (pipe and chimney device). What popular materials are used for insulation.

For some reason, many do not know or do not pay due attention to the fact that the cylinder needs care and protection from external factors impact.

In private houses, a chimney is indispensable. To date, boilers with a complex engineering design are being installed that bring combustion products to the street. Its high reliability has a positive effect on the efficiency of the boiler and on the efficiency of the system as a whole.

Why insulate a gas cylinder on the street

The need for insulation is due to the consideration that the gas cylinder on the street could not freeze, and could effectively remove combustion waste that is constantly generated during the operation of the heating device.

Also, with thermal insulation functioning, there is a natural increase in efficiency in boilers, regardless of the type of fuel: gas, firewood, peat, coal, oil, sawdust.

The warm gases cool down as they pass through the instrument tube, transferring their heat to the walls of the (metal) tube that carries the gases out. And the draft depends on how quickly the walls of the chimney heat up. When the draft drops, smoke is possible in the room where the boiler is located. There is a risk of gas poisoning.

The traction force is also affected by the time during which the moment of condensate appearance is overcome (the time spent on preheating the static flue duct). This indicator depends mainly on the material of the pipe (static flue duct). If an insulated brick chimney has an average of 20-35 minutes, then the same steel chimney - 2-5 minutes.

Naturally, it is impossible to completely avoid the appearance of condensate in the chimney space: the heated cylinder constantly interacts with cold outside air. But it is quite possible to reduce the amount of condensate by properly insulating the chimney.

When condensate forms, water and combustion products (carbon dioxide) mix in the pipe, a powerful acidic solution appears. Acid gradually penetrates the walls of the chimney and slowly destroys it.

For example, a brick pipe absorbs moisture into its walls, which is fraught with its freezing if the heating is turned off during the heating of the gas cylinder in winter. Or there is a frequent intermittent shutdown of the device for a short time(temperature jumps occur, the pipe will wear out faster, it will lose its properties).

Can be found modern houses where the chimneys from the stove and fireplace go straight past the loggia to the roof. In this case, the loggia must be thoroughly secured and insulated.

The main factors that indicate the need for chimney insulation:

  • with insulation and waterproofing, you will not wonder: “why is the gas cylinder covered with frost?” or “why is it so affected by precipitation?”. Their impact on the gas cylinder will be minimized;
  • reduced heat loss in the room correct installation insulation on the pipe;
  • the appearance of condensate on the outside of the chimney is minimized;
  • the appearance of the chimney will acquire an attractive aesthetic appearance.

These important reasons force and motivate us to make high-quality thermal insulation of the exhaust pipe on the street.

What materials are used

Materials should be selected taking into account their operational service. Insulation will last more than one year, only if it is made of high-quality refractory material with a low specific gravity, and installed in accordance with all the rules (professionally).

Most often, these materials are:

  1. different lukewarm (mineral wool);
  2. glass wool;
  3. basalt slabs;
  4. red or rubble refractory brick;
  5. galvanized sheet.

These materials are refractory, durable, neutral to any chemical. environment, are simple in operation, have an affordable cost. They are quite flexible, easy to bend, so they are often used to work on objects with a complex geometric shape for heating a gas cylinder from the outside.

Important! Protect your eyes Airways and hands with special individual means when insulating the chimney with glass wool.

When insulating, the most popular are: brick, glass wool, mineral wool. The choice is made taking into account what material the chimney of your gas column is made of.

Basalt mineral wool tiles are gaining particular popularity. Having low thermal conductivity, it is considered the best for cylinder insulation. It qualitatively and stably supports the necessary minimum temperature outside of the casing.

Its main advantages and disadvantages:

  • perfect safety, environmental friendliness of the material;
  • the minimum number of tools needed when working: tape measure, hacksaw;
  • high resistance to ultraviolet, fungus;
  • the possibility of fitting the material to any geometrically complex configuration of the chimney;
  • service life is 50 years or more.

Nowadays, most often, chimneys for gas and solid fuel heating appliances are made of brick, steel, asbestos pipes.

Types of insulation

The most difficult chimneys for insulation are brick. There are 3 main ways to insulate them (which can be used to insulate chimneys and from other materials):

  1. Insulating plaster is applied. A special solution is made, which is placed in a thick layer - min. 4 cm per pipe. According to the recommendations of experts, it is necessary to apply from 5 to 7 plaster layers.
  2. Warming takes place with special basalt mines. wadded or asbestos-cement slabs. The minimum thickness of such a plate should be 5-6 cm. The fastening is made with a facing mixture. A reinforcing mesh is laid on top of the insulation. After these works, plastering is carried out.
  3. The easiest way to insulate is with wooden shields. It is carried out in stages: for a start, a special building is being built. wooden frame along the perimeter of the pipe (can be made from timber); a gap is left between the materials of 15-17 cm; the frame is sheathed flat slate; gaps are filled with slag or sand, periodically ramming their mass; at the end, a decorative framing of the frame is made with colored prof. sheets, which are fastened with roofing screws.

Note! Any insulation saves heat in your home by 25% on average.

Precautionary measures

Isolation has its own characteristics and certain rules necessary security measures, established recommendations.

Before performing insulation work, it is necessary to check whether the structure is installed correctly and whether there are any defects.

The street chimney must meet all technological requirements and standards:

  • For best optimal traction, the pipe should be at least 5 meters high.
  • Between roofing parts (such as rafter system, ceilings, other parts subject to fire) and a cylinder, a distance of at least 25 cm is allowed.
  • If the roof has combustible materials such as roofing felt, slate, ondulin, then a spark arrester must be installed on the insulated pipe. This is a mesh of stainless steel, a plate that surrounds the top of the chimney. And so that any debris does not get there, the mesh is usually covered with a special metal cap.
  • Once again, make sure that the purchased insulation materials are non-combustible.
  • Carefully study the instructions for the thermal insulation material.

Advice! If you yourself are engaged in pipe insulation, it is recommended to use a convenient roll material insulation, which is attached alone, without difficulty and stress.

Finally

No chimney gas boiler can not do without high-quality insulation. It heats gas cylinders, extends the life of the entire structure, and saves heat costs. With its help, you will avoid fire, protect yourself from carbon monoxide.

The correct, well-equipped chimney system affects the heating efficiency of your home. Thermal insulation is a very responsible process, which includes the insulation of the chimney from the outside.

The market offers many various options for warming gas pipes. Installation is done independently or with the help of masters. The main thing is to make sure once again that the chimney system meets all the requirements, otherwise any insulation will go down the drain, you will waste money, effort and time.
