Ceramic chimney of which company to choose? Ceramic chimneys: installation. Russian-made ceramic chimneys Ceramic chimneys in concrete or stainless steel casing

The chimney in the house can be with various functions. It is mounted to ensure the removal of smoke from a fireplace, a stationary stove. Chimneys are also laid out to remove combustion products during gas heating. If previously such structures were built from red, now they are used for chimneys.

Main characteristics of ceramic chimneys

In such products, the main thing is a long service life. All manufacturers give a guarantee of 30 years for their ceramic chimneys.

Important. Despite this indicator, a ceramic chimney has a service life of about 100 years.

A distinctive feature of this product is that it has excellent technical properties and characteristics.

So, a ceramic chimney has:

resistance to weather and climatic phenomena;
the ability to withstand both fairly high and low temperatures;
durability;
practicality;
wear resistance;
small weight.

The last indicator of technical characteristics favorably affects the construction process, since the ceramic chimney does not exert additional loads on the structure.

Advice. Even with a small mass, ceramic ones must be mounted on a specific foundation. This will give the overall stability of the entire structure.

Disadvantages of this product

All of the above refers to the advantages of ceramic chimneys. As disadvantages, fragility and a small mass can be noted, although the latter indicator will also easily become an advantage in construction.

Shape of ceramic chimneys

At the moment, all chimneys of this type are made only in a round shape. The surface of the product is smooth both inside and outside. This allows high-quality removal of smoke and a variety of combustion products. Also, pipes, thanks to such a surface, do not often become clogged.

Advice. Despite this, it is still necessary to regularly clean the ceramic chimney from soot and leaves that have fallen into it.

Technical characteristics of ceramic chimneys

The walls of the ceramic chimney can be 15 mm thick. In some cases, there are models with a wall thickness of 4 mm. Any ceramic chimney has its own design. It consists of:

ceramic pipe;
insulation;
exterior stone finish.

Pipes are connected with couplings.

Important. You can simply purchase a ceramic chimney pipe, insulate it yourself and ennoble it from the outside. And you can immediately buy ready-made chimneys based on ceramic pipes.

How to choose the right ceramic chimney

At the moment, the market for such products has a wide range. All ceramic chimneys differ not only in their cost, but also in their individual technical characteristics:

wall thickness;
length and so on.

There are also various manufacturers of these products.

Important. As a rule, the seller says the cost of a ceramic pipe separately from a heater and a stone box. This is a lie. The price of ceramic chimneys is set completely for all its elements.

The most popular companies of ceramic chimneys

Among the many manufacturers of ceramic pipes for chimneys, only two are very popular:

Schiedel.
Effe2.

In some respects there is a similarity between these products, and in some respects there are differences.

Chimney from Schiedel

Schiedel ceramic chimneys have excellent properties and characteristics. The manufacturer produces a ceramic three-layer pipe, which is insulated with mineral wool, a stone block is installed on top of it.

This product is distinguished by its versatility and originality of its design. That is, ceramic will not spoil the external design of a building of any type.

The main advantage of this company's ceramic chimneys is that these structures can be installed at a distance of 5 cm from any flammable surface. The safety of using the product is ensured by a non-standard metal plate, which protects the chimney from overheating and prevents nearby buildings from igniting.

The Schiedel chimney pipe is light in weight and diameter. That is, during its installation there will be no problems, it will not clutter up the external space. Pipes can be built-in or external.

Important. In some cases, buyers try not to purchase ceramic chimneys due to their high cost. All of these are false statements. The price of such products is low.

Effe2 chimneys

The Effe2 ceramic chimney consists of several elements:

pipe;
condensate receiver;
construction with an inspection door;
element with a hole for connecting equipment;
cover plate;
profile for the manufacture of a profile;
heater and so on.

These are the basic building blocks.

Chimneys of this company have high fire resistance and the ability to work under the influence of a temperature of 600 degrees. The tightness of the chimney structure will be at a high level. The service life of this product is at least 40 years. Also, ceramic chimneys from this manufacturer are corrosion resistant and light in weight.

Important. You can mount this type of product on the console. A specific foundation for the chimney is not required.

There are a large number of additional elements that will help you install ceramic chimneys. Installation is quick and easy. If there are irregularities in the walls of the building, or the chimney rests against the rafters of the roof structure, then you can turn the pipe in any direction and at any angle.

Important. The main thing is that all these actions comply with the established safety measures for the use of a chimney structure.

in the structure of any company

Installation of a ceramic chimney is easy to perform. The main thing in them is to observe safety precautions and correctly perform all actions. Initially, you need to make a console. This element will be the base for the chimney.

Important. The size of such a base must correspond to the insulation and finishing material.

Next, a condensate collector is installed. Then a ceramic pipe is mounted in it. All connections of this pipe must be sealed using special means. Then carry out work on the insulation and external improvement of the chimney. It can be a ready-made stone box of a certain company. It is also possible to make a box yourself out of brick or use fire-resistant drywall for this. Its surface can be lined with natural or decorative stone from the outside.

German smoke exhaust systems are of high quality, reliability and good thermal performance. Tona chimneys are a clear confirmation of this statement.

Tona products are distinguished by thoughtful design, the use of HEIGHTECH (special structure) ceramics, as well as a wide range of accessories offered to the consumer.

About Tona

The German manufacturer of chimney pipes Tona has existed since 1891. From the very beginning of the company's existence, the consumer has been offered high-quality ceramic pipes. The whole process, from the preparation of clay to the receipt of finished products, is controlled by the company's employees.

Tona has its own quarry, which allows us to reject second-rate clay and constantly monitor the quality of raw materials.

Ceramic chimneys from Germany Tona are manufactured using the HEIGHTECH method, which ensures high strength, heat resistance of the structure, with relatively low weight.

Advantages of the HEIGHTTECH solution:

Acid resistance.
Smaller wall thickness and, accordingly, weight.
Reducing the number of joints.
Fast and uniform heating of the structure.

Tona chimneys are optimally suited for all operating conditions. If necessary, you can use systems for baths, fireplaces, boilers running on gas, liquid or solid fuels.

Types of chimney pipes Tona

Tona smoke extraction systems offered to the consumer have the following characteristics:

Dimensions - the consumer is offered pipes with a diameter of 80 to 300 mm, a length of 500 and 1000 mm.
Type - systems with top and bottom connections are provided for connection.
Design features- the company offers one and two-way pipes with and without a ventilation duct.

The Tona range of smoke exhaust systems includes four basic modifications.

Three-component pipes Tona tec iso

The Tona tec iso chimney system is designed to be connected to heating appliances, regardless of the type of fuel used and the principle of operation. The main features and technical characteristics of pipes are:

The upper and lower connection of the boiler to Tona tec iso is provided. The system is designed for indoor and outdoor installation. To seal the joints, a special mineral-based sealant is used.

Two-component chimneys of the Tona tec system

Tona tec ceramic chimneys are a two-component system for the removal of flue gases with heating temperatures up to 600°C. Depending on the type of boiler, the joints are sealed with mineral (KIT) or silicone sealant. The use of KIT makes it possible to withstand the maximum surface heating up to 1000°C without depressurization of the system.

Tona tec two-component ceramic pipe has different characteristics and purpose, depending on the sealant used:

Cerasecur is a silicone base used for low temperature heating units. Ideal for connection to a condensing gas boiler. Use for any equipment with the closed combustion chamber is allowed. Maximum operating temperature 160°C.
KIT is a mineral base, the parameters are calculated for operation at a temperature of 400°C. Short-term heating up to 600°C is allowed. It is used when operating with liquid fuel and gas boilers with a closed and open combustion chamber.

The Tona tec ceramic chimney with two channels is supplied with a special outer shell made from lightweight concrete. Sealant is selected independently.

The Tona tec two-way chimney with ventilation is the optimal solution for rooms with limited space and insufficient air circulation. During the operation of the boiler, oxygen from the street is burned, which enters the boiler room through the ventilation duct.

Chimneys with stainless steel casing Tona star

Ceramic chimney pipes with stainless steel outer sheath Tona star are popular due to their simplicity and lightness of construction, as well as good appearance.

Modification features:

Real German Tona star chimney systems, unlike fakes, have an internal ceramic layer. On individual branches, adapters and revision elbows, the company logo is embossed.

Chimneys series Tona tec san

Installation of Tona tec san ceramic chimney pipes allows you to repair an existing channel or to refurbish the system. The series has technical parameters that allow it to be used in the following cases:

The removal of condensate, which is formed in a small amount, is carried out thanks to a special condensate drain system. Installation of the pipe is carried out by means of installation in an existing chimney.

Features of the installation of chimney pipes Tona

The technical documentation supplied with the Tona Fume Extraction Kits provides installation instructions. Depending on the selected modification, the connection features may differ slightly.

Before starting installation work, it is necessary to carefully study the manufacturer's recommendations and take into account the existing SNiP, as well as fire safety requirements.

Foundation requirements for Tona pipes

Tona tec and Tona tec iso systems are distinguished by their high weight due to the outer shell (blocks) made of porous concrete. Before installing the modifications, you will need to make a foundation for the installation of expanded clay concrete blocks.

Exceeded the dimensions of the blocks by at least 20 cm.
It was monolithic, reinforced.

The Tona star and Tona san systems are lighter and can therefore be mounted on a support bracket. There is no need to make a foundation.

Rules for organizing the passage of overlap

The norms associated with the passage of the overlap are clearly specified in the SNiP. In particular, the safety distances from the chimney to combustible materials are indicated there. For double insulated pipes, the minimum distance to the wooden surface is at least 3 cm.

When installing single-wall smoke exhaust systems, it will be necessary to increase the gap to 5 cm. The distance from the tree to the chimney is filled with non-combustible mineral insulation.

When mounted through concrete slabs, no fire clearance is required. But, the diameter of the hole is expanded by several centimeters to facilitate installation and thermal expansion.

Installing a Tona chimney in a wooden house requires special care. Pipes should not be closer than 1 meter from the supporting structures.

How is the output through the roof

The output of the pipe through the roof requires the manufacture of a special penetration, a wooden frame, the gaps in which are filled with insulation up to the chimney. During installation work, the following conditions are observed:

Chimney trim brand Tona

The chimney of Tona tec and Tona tec iso is located in concrete blocks, made of light porous material exposed to moisture and dampness. To protect the structure, it is necessary to clad the walls with ceramic tiles or a layer of plaster.

The cladding is carried out using adhesives designed for outdoor use, able to withstand heat and temperature fluctuations. The installation of a ceramic chimney Tona in the bath may require the additional use of a reinforcing mesh when plastering the frame.

The primary function of the chimney is to remove combustion products from the furnace to the outside, but its role in the process of fuel combustion and draft formation cannot be underestimated. Experts say that with the right choice of material for the chimney pipe and its proper installation, the heat transfer of a furnace or boiler can be increased up to 10-15%. However, for or, and the furnace will need a chimney not only of different heights and diameters, but also of material. If earlier they chose only between brick and non-galvanized metal, today the range of suitable options is much wider. We understand what materials for the chimney, or rather chimney pipes, exist, for what conditions they are intended, and which chimney to choose depending on the type.

What to consider when choosing a material for a chimney?

The chimney is complicated structure consisting of vertical pipe, rain protection hood, inspection window for maintenance, condensate collection tray and other items. The vertical pipe is considered the main part of the chimney, and safety and operational efficiency depend on it.

To choose the right chimney material, you need to clearly understand what fuel will be used: natural gas, diesel fuel, coal, firewood, peat or sawdust. Each of them has a different combustion temperature, temperature and composition of the exhaust gases. Therefore, when choosing a material for a chimney, such parameters are taken into account:

From all this it follows that:

for wood stoves, solid fuel boilers, and fireplaces it is necessary to choose a material that can withstand a working temperature of about 700 0 C and its short-term increase to 1000 0 C. These are brick and less often ceramic chimneys;
for gas boilers a chimney is required that can withstand temperatures of 200 0 C with a short-term increase to 400 0 C. Metal pipes are usually used for this purpose;
for oil and sawdust boilers a material for the chimney is needed that can easily withstand temperatures up to 250 0 C with an increase to 400 0 C, and if we are talking about diesel fuel, then it is also resistant to the aggressive environment of exhaust gases.

Now let's look at the properties of the most popular materials that are used to equip the chimney pipe.

No. 1. Brick chimney pipe

Brick for the arrangement of chimneys has been used for a long time, and it has already become traditional material. Today it cannot be called universal, which, however, does not reduce its popularity. A brick chimney is equipped inside the wall of the building, those sections of it that pass through unheated rooms or outside the building, carefully so that the flue gases inside do not cool. For the arrangement of such a chimney, grades not lower than M150 are suitable; they are used for its masonry.

To the main advantages of brick pipes for the chimney their durability and excellent heat resistance (can withstand temperatures up to 800 0 C), and outwardly they look great, and in terms of fire safety they have practically no equal. Brick chimney suitable for wood burning stoves and fireplaces, and when working with boilers for liquid fuel, gas, pellet and solid fuel pyrolysis boilers, it quickly collapses. The thing is that such boilers are designed in such a way that the exhaust gases have a low temperature. They quickly condense and settle on the walls of the pipe, due to which the latter are constantly moistened. Given the fact that the exhaust gases contain aggressive chemicals, including sulfuric acid, the brick quickly collapses. The results of such exposure are manifested by wet spots on the outer surface of the pipe.

True, there is always a way out of the situation. To connect a modern gas or liquid fuel boiler to a brick chimney pipe, in brick channel embed steel or ceramic pipe, which have slightly different performance characteristics.

Since the surface of the brick is rough, soot settles well on it, which gradually leads to a decrease in traction. Cleaning and repairing a brick pipe is not an easy task. In addition, the large weight of the structure will definitely require availability. On the other hand, it is difficult to find a worthy analogue for arranging the chimney of a stove or fireplace.

No. 2. Steel pipe chimney

For gas and solid fuel boilers steel pipes are best suited, but at the same time it must be stainless, heat and acid resistant, since sulfur particles, which are present in almost every type of fuel in one quantity or another, when combined with moisture and coal particles form an aggressive environment. Stainless steel capable withstand temperatures up to 500 0 С, pipes with a wall thickness of 0.6 mm are used for arranging chimneys, but for it is better to use steel with a thickness of 1 mm. Steel pipes are a whole system of straight sections and various shaped elements, incl. adapters, bends, tees, etc. Such a system can be mounted independently or be built into an existing brick channel.

The main advantages of steel pipes:

simplicity and high speed of installation, because the weight of the structure is small, there is no need for a foundation, and not even the biggest professional will assemble the entire system from ready-made elements;
repair work is easy to carry out;
soot particles do not accumulate on smooth walls, their surface is easy to clean, so we can talk about consistently high aerodynamic characteristics for the passage of exhaust gases;
high corrosion resistance;
the ability to create complex structures;
high tightness, due to which it is possible to create a forced hood.

Among the cons they call a high cost, especially when compared with a brick or ceramic counterpart, but if simplicity and speed of arrangement, low weight and resistance to aggressive environments are important, then it is better to stop the choice on a steel chimney. The disadvantages are sometimes attributed to low heat resistance, but for modern boilers with a slow-burning system, greater heat resistance is unnecessary.

Depending on the characteristics of the room, boiler and climate, use one of the following types of steel chimneys:

single wall steel pipe consisting of a single layer of stainless steel. This is the easiest and cheapest option, they lay such a chimney in a specially laid out vertical channel. Often such chimneys, and the waste heat from the steel pipe is used to heat water;
single-wall steel pipes for the reconstruction of a brick chimney may be oval. A similar restoration process and the adaptation of an existing chimney to work with a gas boiler is called a “sleeve”;
double-walled sandwich panels, consisting of two steel pipes, in the space between which a layer of insulation () is placed. The use of the latter makes it possible to prevent the formation of condensate inside the pipe, while its outer surface almost does not heat up. Ease of assembly and excellent performance make it possible to use such systems both indoors and outdoors on the wall;
steel coaxial chimneys also consist of two pipes placed one inside the other, only there is no insulation between them, and the resulting space is designed to supply air to the boiler to maintain combustion. The combustion products are discharged through the inner pipe. Such chimneys do not behave very well in harsh domestic winters. Cold outside air passing through the outer pipe can sometimes greatly cool the inner pipe and gases flowing through it. This leads to a sharp loss of condensate and its freezing on the surface of the pipe. The chimney is gradually clogged, and the automation, reacting to this, turns off the boiler, so in this case it is better to equip chimneys with two separate pipes.

It is worth noting that sometimes thick low-alloy steel pipes are used to equip the chimney - this option is usually found in sauna stoves. Also, craftsmen are sometimes used for the same purposes.

Number 3. Ceramic chimney pipe

Ceramic chimney pipes are considered the most versatile, and among them main advantages:

For the installation of a ceramic chimney, a separate channel is required. The shell is equipped with special voids. A layer of mineral wool insulation is placed around the pipe to protect adjacent structures from excessive heat and reduce condensation. Both the pipe and the thermal insulation are able to absorb water, so they need to be provided with a normal one. It is created due to the presence of vertical air channels between the insulation and concrete blocks. By the way, in concrete blocks there are also channels for placing reinforcement in them. Be sure to reinforce the part of the chimney that goes outside.

To expand the scope of use of ceramic chimneys, they are produced in steel case, and also in the form rectangular elements. The former do not require the arrangement of the foundation and the creation of special channels, the latter can be used for the reconstruction of brick chimneys.

No. 4. Chimney from asbestos-cement pipe

A couple of decades ago, asbestos-cement pipes were widely used to equip chimneys. Actually, initially they were not intended for such purposes, which is easy to verify by studying their performance. Of the advantages of the material, only its low price, but shortcomings much bigger:

You can use an asbestos-cement chimney pipe only if you are sure that the installation will be done correctly, and also if the chimney is cleaned regularly, but it is better to pay attention to other options.

No. 5. Vermiculite chimney pipes

Not so long ago, vermiculite chimney pipes appeared on sale. These are stainless steel pipes coated inside with a 5 cm thick layer of vermiculite mineral. This mineral has low thermal conductivity, therefore, in fact, it is a natural heat insulator. Moreover, vermiculite is absolutely inert to aggressive combustion products.

Among the others benefits vermiculite pipes high durability, relative ease of installation, no need for chimney insulation. Basic flaw lies in the ability to accumulate soot, so you will have to clean the chimney often.

Other options

At the moment, there are other ways to equip the chimney:

glass pipes a few years ago they would have caused bewilderment, but today their advantages are undeniable. Glass does not accumulate soot and soot, is easy to clean, inert to aggressive environments and withstands high temperatures. But a glass chimney will be expensive, it is difficult to equip it, additional thermal insulation will be required, and sealing of joints is complicated, therefore, so far such an extravagant method has not become widespread;
concrete blocks and self-cast concrete chimneys are called in some sources an alternative to brick chimneys. Professionals strongly criticize this option and recommend not playing with fire: concrete will not withstand serious temperature loads, and it is impossible to make a heat-resistant compound at home.

Finally, we note that before choosing a material for a chimney, it is necessary to choose a boiler or decide on the design of the furnace. In addition, it is worth considering the design features of the building, and it is best to think through all the nuances of its future heating even before the start of building a house. It is better to entrust the calculations of the chimney channel for your safety to a specialist.

Each country house that is heated by a gas, liquid or solid fuel boiler must be equipped with a chimney. Brick, stainless steel, ceramic and asbestos-cement pipes can be used as a material for the chimney. Ceramic chimneys are by far the best solution to the problem of removing the products of combustion of recycled fuel.

They are superior to brick and metal flues in all respects, and a ceramic chimney should not even be compared with asbestos-cement pipes. After all, asbestos smoke channels are dangerous from the point of view of all fire and sanitary standards.

Components of a ceramic chimney

Ceramic chimneys are a structure consisting of 3 elements. Smoke channel structure:

The inner layer is a ceramic chimney pipe.
The middle layer is a heat-insulating material.
The outer layer is a protective concrete shell.

Ceramic chimneys are conditionally divided into several parts. The device consists of the following elements:

Foundation.
main part.
Head that goes to the roof of the building.

The main receiver of the device must be equipped with the following elements:

Tee for connection to a heating device (boiler, stove, fireplace);
Revision for viewing and cleaning;
Ventilation grill.

Ceramic pipes for chimneys are equipped on top with an umbrella-head or deflector to protect against wind and precipitation.

What are the main advantages and disadvantages of ceramic pipes

Ceramic pipes for chimneys are made of refractory clay. There are several different options for devices, which allows you to choose the best option for both high-temperature and low-temperature boilers.

The ceramic chimney pipe has the following positive characteristics:

High temperature resistant;
Resistance to temperature extremes;
Resistance to corrosion;
Strength;
Density, which does not allow gases to penetrate through the walls;
Thermal conductivity;
Low roughness;
Long service life;
Ease of installation.

Ceramic chimneys are expensive. It is the price that is the main disadvantage of this type of device.

In addition, the disadvantages include:

The large weight of the structure, which requires the mandatory installation of a foundation;
Possibility of installation only in vertical position.

Varieties of ceramic chimneys

Ceramic chimneys are sold as a finished three-layer structure, where basalt or mineral wool enclosed in a stone shell is used as a heater.

Ceramic chimneys are of the following types:

One-way;
Two-way;
With ventilation valve;
Without vent valve.

Basic requirements for the height of the structure

There are structural height requirements for ceramic smoke ducts. So, the size from the boiler to the mouth of the pipe should not exceed 5 meters. However, we should not forget that the thrust also depends on the height of the pipe. The height of the flue above the roof is determined based on the following rules:

On a flat roof, the height is 1.2 m.
On a pitched roof, when the chimney is less than 0.5 m from the ridge, the elevation should be 0.5 m from the level of the ridge.
At a distance of 1.5-3 m from the ridge, the height should be equal to the line of the ridge.
If the distance from the ridge is more than 3 m, a height of at least 10 ° from the ridge line above the horizon is allowed.

The best and most reliable chimney

How to choose the best chimney

Not quite correctly understanding how the chimney works and how it works, a person in any case seeks to find out how to choose the best chimney.

Types of chimneys

In his view, an ordinary person understands that a chimney is needed only in order to perform the function of removing combustion products into the atmosphere, which are formed during the combustion of fuel. But it is worth considering that this does not end with all the functions that a chimney can perform.

Everyone knows the fact that in order for any fuel to burn, oxygen is necessary. It enters the furnace from the air.
You are free to think that the more air that enters the firebox, the better.
This option is not entirely correct. Everything should be in moderation.

Those who are directly connected with cars will be able to correctly understand that the operation of any boiler, fireplace or stove is no different from how an internal combustion engine works. When there is an overabundance or deficiency of fuel, this leads to the fact that the power may weaken, and the engine will not be stable and this will lead to excessive fuel consumption.

If you look at it from a general point of view, it turns out that the chimney is an integral part of the looped system.

Exhaust gases that pass through the chimney enter the atmosphere, because of this, a vacuum occurs in the main part of the boiler or furnace, and fresh air enters the furnace from the atmosphere.

When it mixes with fuel, it burns out and, due to heating, goes up through the chimney and this happens until the fuel is available in the furnace.

It will be interesting what happens when the type of your heating device is absolutely not suitable?

Then it will be clear that the entire chimney circulation cycle will be damaged. Then in the end:

Fuel combustion will not be correct.
The operation of the heater will become inefficient.
There will be excess fuel consumption.
It will become possible that carbon monoxide gases will penetrate into the room.
A big chance for a fire. Therefore, the question of which chimney will be better should instantly go into what types of chimneys are, what are their features and functions, and how they will behave with other heating appliances.
The functions of the chimney include such options as what conditions it should provide when complete combustion of the fuel occurs, without the possibility of its overrun.
It must guarantee durability, easy maintenance and installation.

Whatever the quality chimney made by hand or bought, and how highly qualified the installer is, the most important reason is the applicability of this type of chimney to one particular heater. Nowadays, the types and range of chimneys are very deep (see Chimney device), they differ from each other in design and material. Now we will take a look at some of them.

Brick chimney

Chimney made of bricks

The most popular material for chimneys has been and will be such material as brick. But not every type of brick is suitable for a brick chimney. A brick such as silicate does not tolerate heat very well, so it should not be used to build chimneys. All used ceramic bricks for the construction of ceramic chimneys are an elite type of brick for this business. But still, not all models of ceramic bricks are suitable for chimney designs.

Advantages of a brick chimney

A brick chimney goes well with the interior of absolutely any house where you live. It is a great addition to the look of housing from the outside.
The draft of just such chimneys, which is relatively low, makes it possible to use them for their intended purpose with units that heat the room on wood fuel.
Another plus is considered to be the low price policy of a brick chimney.
A chimney made of brick perfectly accumulates heat.

Cons of a brick chimney

The first minus of a brick chimney is the bulkiness of brick chimneys.
When installation takes place, an indispensable foundation device is necessary.
A rough surface is instantly clogged with soot and requires frequent cleaning.
When you use other types of fuel or use modern heating appliances, this can lead to the appearance of condensate in such chimneys, which destroy it.
In practice, it has been proven that damage to the chimney occurs already 2-5 years after you start using it intensively.

Modular chimneys are made from a material such as stainless steel and their cost is slightly more expensive than brick ones.

By welding, such chimneys are made of high quality material in an inert gas environment. The structure of such chimneys resembles a “sandwich” (see Sandwich chimneys).

The modular chimney is made of high-quality steel inside, after which a layer of thermal insulation is laid and at the end, that is, a layer of high-quality metal is laid on top, which performs the function of protection, it is usually stainless or galvanized steel.

Advantages of a modular chimney

Installation is carried out without the use of a foundation due to its ease.
Quick installation is facilitated by the presence of various elements.
It can be used with any type of fuel and with any heating unit due to its versatility in use.
The ability to withstand a sharp impact of condensate, which have a heating temperature of 600 degrees or less.
It is possible to design chimneys of various shapes.
Guarantee in operation not less than 10 years.

Cons of a modular chimney

Pretty high pricing.
The requirements in the instructions must be followed when mounting. The ability to independently install a chimney is not given to everyone.
Mistakes made during the installation and connection of a modular chimney can lead to tragic consequences.

Ceramic chimneys

A sample of a ceramic chimney is represented as a resistant pipe made of ceramic material, that is, heat-resistant ceramics and placed in a specialized shell made of brick, expanded clay concrete or other material.

Assembly conditions:

It is worth starting to assemble the chimney from separate segments (see Ceramic pipes for chimneys), the seams are sealed with a special sealant when connected.
The outer shell is also assembled in segments and is a floor block, where the chimney itself passes inside, there are still holes for reinforcing metal rods.
The blocks are fastened with a common solution. The insulating layer is located between the ceramic pipe and the outdoor units, which is made of refractory material provided for its intended purpose.

Advantages of a ceramic chimney

They differ from other chimneys in their versatility. They are used with different units for heating and with different types of fuel.
Ease of installation and versatility for mounting in any building.
Possibility of manufacturing a complex chimney tracing.
Fire safety at a high level.
Warranty for at least 30 years.

Cons of ceramic chimneys

The high price policy of ceramic chimneys, despite the comparison with modular chimneys, is much more expensive than brick chimneys.
Bulky and oversized size and weight, as well as an indispensable foundation device.
When mounting the chimney on the roof, it is necessary to strictly follow the rules for the assembly of the chimney and the rules for the use of reinforcing materials.

There is another type of chimney, such as a special one - special chimneys are made from the materials that are in the house. As a rule, such chimneys are made of ordinary steel or asbestos pipes.

It makes no sense to focus on chimneys of this kind.

The reason for this is the dubious advantages of a low price, that apart from this, nothing else can be bought better and better.

But the risk of trouble is very high, they can overtake the owners of such chimneys at any moment.

It will not be 100% possible to achieve efficient and progressive operation of the heating unit, that's for sure.
Another unpleasant moment may be the explosion of a special chimney and, as a result, a fire.

Which chimney to choose

The main rule to remember when choosing a good chimney is that it is absolutely not advisable to choose a chimney based on its cost. And yet, which chimney to choose is better based on its varieties.

Naturally, pricing policy plays an important role, but it cannot be called the main one. Therefore, in order to determine which chimney your choice is, you need to use the following rules:

What type of heating will be in your use.
What fuel do you need to heat your home?
What heating unit will you be using?
How will the chimney be installed? If you do not entrust this work to competent specialists, then installation problems may arise, so you need to calculate your own forces for installing the chimney.
Calculate the intensity of use of your current heating system.
Correctly evaluate your experience and knowledge in the field of chimney construction.

These are not complicated rules about which roof chimney to choose. But if you stick to them, then you will be puzzled by the question: which chimney is better to buy? And then it will be clear that the best option will be the chimney that will economically, efficiently and safely perform its functions for your heating system.

If you evaluate the capabilities of a brick chimney that fits your heating unit in all respects, then it is not at all necessary to buy the most modern, most fashionable, super expensive other chimney. Although this question will be left to your own consideration. What should never be forgotten is safety. It is she who is the key to your health.

But whatever you buy, it must do its job safely for you personally and in particular for the individuals that surround you. Good luck in choosing the right chimney for your fireplace, stove or bath.
