What chimney is better ceramics or pumice. Ceramic chimneys - cozy warmth of the country house

Chimney in the house can be with different features. It is assembled to ensure the removal of smoke from the fireplace, a stationary oven. Also, chimneys are laid out to eliminate combustion products gas heating. If previously built such structures from red are now used for chimneys.

The main characteristics of ceramic chimneys

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

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

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

So, the ceramic chimney has:

  • resistance to weather and climatic phenomena;
  • the ability to withstand both quite high and low temperature modes;
  • durability;
  • practicality;
  • wear resistance;
  • small mass.

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

Council. Even with a small mass of ceramic should be mounted on a specific foundation. This will give the overall stability of the entire design.

Disadvantages of this product

All of the above relates to the benefits of ceramic chimneys. As deficiencies, it is possible to note fragility and a small mass, although the last indicator will also easily become advantage of construction.

Form of ceramic chimney

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

Council. Despite this, it is still regularly necessary to clean the ceramic chimney from the soot and from the leaves in it.

Technical characteristics of ceramic chimneys

The chimney walls of ceramics can be a thickness of 15 mm. 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;
  • forest stone finishes.

Connect pipes with couplings.

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

How to choose a ceramic chimney

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

  • wall thickness;
  • long and so on.

There are also a variety of manufacturers of this product.

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

The most popular ceramic chimney firms

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

  • Schiedel.
  • EFFE2.

There is something similar to this product, and in some indicators there are differences.

Chimney from Schiedel

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

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

The main advantage of ceramic chimneys of this company is that it is possible to set the design data at a distance of 5 cm from any flammable surface. The safety of the product is provided by a non-standard metal plate, which protects the chimney from overheating and does not make it possible to fire nearby buildings.

Schiedel chimney tube has a small weight and diameter. That is, when it is installed, there will be no problems, it does not overlook the external space. Pipes can be built-in or external.

Important. In some cases, buyers are trying not to acquire ceramic chimneys due to their high cost. All this incorrect statements. The price of such products is low.

Effe2 chimneys

The EFFE2 ceramic chimney consists of several elements:

  • trumpet;
  • condensate coach;
  • construction with an audit door;
  • element with hole for connecting equipment;
  • coating plate;
  • profile for making profile;
  • insulation and so on.

These are the basic design elements.

The chimneys of this firm have high fire resistance and the ability to work under the influence of a temperature of 600 degrees. The tightness of the chimney design will be on high level. The life of this product is at least 40 years. Also, ceramic chimneys of this manufacturer are distinguished by corrosion resistance, a small mass.

Important. Mock this species Products can be on the console. A certain foundation for chimney is not required.

There are a large number of additional elements that will help install ceramic chimneys. Installation is carried out quickly and simple. If there are irregularities of the walls of the structure, or the chimney tube rests in the rafting roofing structure, then you can turn the pipe to any side and at any angle.

Important. The main thing is that all these actions correspond to the established safety measures for the use of chimney design.

in the structure of any company

Work on the installation of ceramic chimney is easy to perform. In them, the main thing is to comply with security and correct all the 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 with the insulation and finishing material.

Next is the condensate acceptor. Then the ceramic pipe is mounted in it. All connections of this pipe must be sealed with special Tools. Then conduct work on insulation and external chimney. It can be a ready-made stone box of a certain company. It is also possible to make a box independently of the brick or use fire-resistant plasterboard for this. Its surface outside can be lined with natural or decorative stone.

Today brick trumpet For chimney, so popular earlier, already inferior to new, innovative variants of the smoke tube device.

Since boilers on liquid and gas fuel are becoming increasingly distribution, ceramic pipes for chimneys are installed with them.

Use of ceramic chimneys

Such material as ceramic pipes for chimney are increasingly used. In the standard configuration, their functions are reduced to the disposal of burnt gases having different temperatures.

But it is quite possible to get such samples that will be suitable for:

  • boiler on solid fuel (coal, pellets, coke, crumb);
  • gas boiler;
  • fireplace;
  • boiler on liquid fuel.

There are also such ceramic pipes for chimneys that are suitable only for boilers with low work temperature, that is, no more than 200 ° C.

Specifications and advantages of the ceramic pipe

It is not a secret that the chimney ceramic pipe is famous for the whole range of advantages that distinguish it from other materials of this type.

The advantages of such a pipe include the following:


Ceramics chimney system design

The structure of the ceramic chimney pipe is as follows:

  1. The inner layer is made of ceramics.
  2. Material in the middle is represented as a special heat insulator.
  3. The outer lining of the chimney pipe is made by stone blocks.

The following elements are mounted above the ceramic pipe:

Special rules for organizing chimney from ceramics:


Installation of ceramic pipe for chimney

It is important to remember that the installation of chimney pipes from the already ready-made "sandwich structures" should be as follows:

At that moment, when the chimney pipe finish is performed, the modular joints must be placed so that they are not in places the slabs. Otherwise, these parts of the chimney must be equipped with insulation made of non-combustible material.

The whole process of mounting the chimney from a ceramic pipe with video and photos can be easily found on the Internet.

How to achieve good work of ceramic chimney?

The diameter and height of the ceramic chimney pipe, the technical characteristics of a particular boiler, a furnace, or a fireplace have a paramount effect, this is important to consider when.

Designing chimney, it is important to comply with the following rules:

  1. The room, which is the main in the heating system, can be equipped with an uninsulated pipe, but at least at least 60 centimeters from the overlap must be mounted. It is worth remembering that it is necessary to insulate that ceramic chimney, which passes through the attic room.
  2. Chimney from ceramics should have a height of at least 5 meters.
  3. It is important to observe the correct ratio of all parameters of the pipe: its height, diameter and traction force. So, the height of the pipe is directly proportional to the strength of the thrust (the higher the pipe, the stronger the thrust).

    But do not arrange too long chimney, as it can cause a high aerodynamic resistance. Increase and the proportion of gases that give all the heat of the pipe walls, therefore will decrease and the thrust.

    Installation of ceramic chimney, details on video:

  4. It is also necessary to observe the optimal ratio of pipe heights, roofing, ventilation channels and other protruding elements.
  5. It is important to have access to the joints of all structural elements, in addition, they should not be located within the home overlaps.
  6. The clamps fasten the pipe to the wall at a distance of 1.5 - 2 meters from each other, and it is done both in front of the corner allocation and behind it.
  7. Speakers over the roof more than 1.2 meters of pipes are strengthened due to stretching.
  8. Do not forget about the norms fire safety. In the event that the distance between the "sandwich" and the wall made of wood exceeds 60 centimeters, it is important to treat the wooden surface with special substances that are called antipirens.
  9. If there is such an opportunity, it will be better to prevent the connection of several furnaces with different heights with chimels. Each of them is best equipped with a separate chimney.
  10. Perform a work test and care for chimney from ceramics is needed at least 2 times a year, for example, at the beginning and at the end of the heating period.

You need to do the following:

  • perform traction control;
  • check modular joints for tightness;
  • clean the inner surface from the crashed soot (as needed).

Brick today build infrequently: it's too difficult to find a good wizard and suitable material. Systems from finished elements (modules) are much more in demand, allowing you to collect the smoke "highway" in one or two days. For many years, pipes made of steel and ceramics compete on the market. For the first, it is usually a guarantee of no more than 10 years, and on the second - up to 30 years (while the real service life of ceramic pipes exceeds 50 years). Indeed, pottery is more resistant to the effects of high temperatures and caustic smoke condensate, however cost 2.5-3 times more expensive than steel and moreover, extremely demanding on the quality of installation. Such a significant increase in costs justifies itself only with the responsible approach to the selection of the system and strict compliance with the rules for assembling the structure.

Outdoor chimney is preferable from the point of view of fire safety and saving space, however requires best insulation and atmospheric protection /

Ceramic chimneys are presented on russian market ECOTON, EFFE2, SCHIEDEL, TONA and WOLFSHÖHER TONWERKE products. Ecoton, Schiedel and Tona offer complete insulated systems such as Sandwich. Wolfshöher Tonwerke produces only chammed pipes and glue for them - both are used by small manufacturers and assembly firms. The EFFE2 products are positioned by a mansion, from which we will start a review.

Chimney from ceramic modules

Chimney from ceramic modules (EFFE2 ULTRA, EFFE2 DOMUS). It consists of difficult elements cross section - with internal and outer walls and radial jumpers. The working channel can be round (diameter 120-300 mm), oval or rectangular; The external cross section of the pipe is only rectangular.

The TONA TEC LAS system (a) is designed for high pressure flue gases and is intended for heat generators and boilers, which use liquid and gaseous fuel. The insulated Tona Tec Plus system (b) is suitable for boilers, furnaces and fireplaces operating on any type of fuel. The main elements of chimneys: 1 - working channel; 2 - concrete casing; 3 - connection module; 4 - revision; 5 - condensate receiver. Photo: Tona.

A small mass of the design (about 27 kg / mb. M with a channel diameter 140 mm) allows you to do without a foundation; There is also no suction mounting (with a support for a brick or block oven) or installation on the wall console.

The main minus of the chimney from all-tempered modules is associated with insufficient for Russian conditions thermal insulation of the internal channel and, as a result, heavy, especially if equipment with low flue gases (, condensation boiler) is used. You have to acquire an additional thermal insulation casing from pressed stone wati under shuttering or independently assemble a warming box (for example, from dry-fiber sheets with filling basalt Vata.). Another problem is in a relatively low structure strength: it must be located inside the predetermined mine, to be brick or enhance steel corners.

Pros and cons of ceramic modular chimney

Benefits disadvantages

Stands to moisture and acids, compatible with equipment running on gaseous, liquid and hard fuel.

Required to the quality of installation. Pipes are fairly fragile and with incorrect and negligent assembly can crack.

Withstands the short-term effect of the temperature above 1000 ° C (fire soot in the pipe).

Models with concrete casing need a solid base (usually own foundation).

Helps to minimize the amount of smoke condensate; Compatible with devices for collecting and removing condensate.

The complexity of repair and replacement. A partial or complete dismantling of such a chimney in a lounge is difficult.

Eliminates the possibility of leakage of flue gases in the room, some systems are able to work with overweight Gas (gas discontinuities).

Two-channel systems provide and allow combustion air supply.

Chimney with concrete casing

The chimney with a concrete casing (for example, Ecoton S-Block, Schiedel Uni, Tona TEC) is a three-layer "sandwich": an internal ceramic pipe is wounded with thermal insulation material and enclosed in a shell of volatile ceramzite-concrete blocks. The casing not only performs a protective and decorative function, but also gives the design stability. Such chimney can only be indigenous: it is installed next to the heating unit on a general or separate foundation.

The thickness of the pipe walls in different manufacturers varies from 4 to 6 mm; This parameter does not affect performance characteristics Constructions, however, products with thin walls require greater caution during transportation and assembly. The accuracy of the manufacture of fields, which affects the consumption of mounting solution and the tightness of the compounds.

As thermal insulation, ordinary flexible mattes from stone wool can be used or ready-made "shells" from the same material, but higher density. The second preferred in terms of durability and ease of installation, but cost 40% more expensive.

In concrete elements of the casing, holes must be provided for vertical reinforcement rods that ensure the strength of the masonry. When installing outside the building, the casing should be plastered and painted with facade paint.

In the upper part, the chimney is warmed especially carefully using a clay gravel (its advantage - low water absorption) or ready-made cohesives from mineral wool. Photo: "Red roofs"

Chimney with metal casing

Chimney with a metal casing (for example, Schiedel Kerastar) is all the same warm "sandwich", but intended for wall mounting. He is able to withstand outdoor operation and does not need to decide ( outer tube Made of polished stainless steel). Another advantage of such systems is the possibility of assembling the chimney of a complex configuration, crawling rafters and other obstacles (due to the presence of taps 15, 30 and 60 °).

Installation of chimney

The main complexity of the ceramic installation is related to the fact that the design always includes steel elements - the inlet nozzle, the cleaning door, and sometimes also Schieber, the mounting brackets to the walls and clamps. Since steel has a higher thermal expansion coefficient than ceramics, compounds should be performed with a 2-5 mm gap, using asbestos cord or elastic heat-resistant sealant (Fischer DFS GR, Penosil 1500 ° C, etc.).

Tiered furnaces and fireplaces are often equipped with an oven ceramic chimney, which not only serves as an interior decoration, but also allows you to more effectively use heat from the device. Photo: godin.

Pottery pipes are glued with special silicate glue. At the same time, it is necessary to carefully remove the surplus of the working solution, especially from the inner surface of the channel, which should be perfectly smooth, otherwise the pipe will be quickly clogged with soot. Modules of concrete casing are placed on cement glue. Since the height of the elements is small, it is necessary to constantly control the verticality of the chimney using a plumb or laser level.

Fireman indentation from the inner walls of the pipe to unprotected wooden structures should be at least 500 mm; to the insulating screen closed (minvat + steel) - 380 mm.

Finally, it is very important to choose correctly and gently install a headband consisting of a coating plate (usually concrete) and a metal-deflector metallic umbrella. The stove must herdict the gap between the working channel and the casing. After all, if the insulation at the top of the pipe will ignore, the thrust will deteriorate sharply (it is possible even to roll over) and the amount of condensate will increase. Incorrectly made deflector can also cause problems with the burden. In this regard, it is better to purchase a headband from the producer of the chimney, even if it costs more expensive in the scene or ordered in a third-party workshop.



German smoke removal systems are distinguished by high quality, reliability and good heat engineering characteristics. The vivid confirmation of this statement is Tona chimneys.

TONA products are distinguished by a well-thought-out design, the use of Heightech ceramics (special structure), as well as a wide range of components offered to the consumer.

About company TONA manufacturer

The German producer of chimney pipes tone existed since 1891. From the very beginning of the company's existence, the consumer offers high-quality ceramic pipes. The whole process, from clay blank and before receiving the finished products, is controlled by employees of the company.

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

Ceramic chimneys from Germany are manufactured using the Heightech method, which ensures high strength, the heat resistance of the design, with a relatively low weight.

Advantages of Heightech Solution:

  1. Acid resistance.
  2. Ligger wall thickness and respectively weight.
  3. Reducing the number of joints.
  4. Fast and uniformized design.
Tona chimneys are optimally suitable for any operating conditions. If necessary, you can use systems for baths, fireplaces, boilers working on gas, liquid or solid fuel.

Types of chimney pipes tone

The consumers offered by the consumer of the TONA chim response system have the following characteristics:
  • Dimensions - the consumer offers pipes with a diameter of 80 to 300 mm, a length of 500 and 1000 mm.
  • Type - For connecting, systems with upper and lower connections are provided.
  • Design features - The company offers one and two-way pipes with a ventilation channel without it.
Four basic modifications are presented in the line of systems of smoke-performance TONA.

Three-component Tona Tec ISO pipes

The chimney system TONA TEC ISO is designed to connect to heating devices, regardless of the type of fuel used and the principle of operation. The main features and technical characteristics of pipes are:

Provided upper I. lower connection Boiler to Tona Tec ISO. The system is designed for domestic and outdoor installation. For sealing joints, a special mineral sealant is used.

Two-component chimneys of the TONA TEC system

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

Two-component ceramic Tona TEC pipe has various characteristics and the purpose, depending on the sealant used:

  • CERASECUR - Silicone base, is used for low-temperature thermal units. Optimally suitable when connected to condensation gas boiler. It is allowed to use for any equipment with closed chamber combustion. Maximum operating temperature 160 ° C.
  • Whale - mineral base, parameters are designed for operation at a temperature of 400 ° C. A short-term heating is allowed to 600 ° C. Applied during operation with liquid fuel and gas boilers With a closed and open furnace chamber.
Tona TEC ceramic chimney with two channels is supplied with a special outer sheath made on the basis of light concrete. The sealant is selected independently.

Tona Tec two-way chimney with ventilation is the optimal solution for rooms with limited area and insufficient air circulation. During boiler operation, oxygen is burned from the street entering the boiler room through the ventilation channel.

Chimneys with stainless steel shell Tona Star

Ceramic pipes with outdoor stainless steel shell for Tona Star chimneys are popular due to the simplicity and ease of construction, as well as good appearance.

Modification features:

The real German chimney systems TONA STAR, in contrast to fakes, have an internal ceramic layer. On separate taps, adapters and revision knees, the company's logo is knocked down.

Chimneys of the Tona Tec San series

The installation of ceramic chimney pipes TONA TEC SAN allows you to repair an existing channel already or repaid the system. Series has technical specificationsallowing it to use it in the following cases:

The condensate removal generated in a small amount is carried out thanks to a special condensate system. Installation of the pipe is carried out using the installation in an already existing chimney.

Features of mounting chimney pipes tone

In the technical documentation attached to sets of TONA smoke systems, installation instructions are given. Depending on the selected modification, the features of the connection may differ slightly.

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

Requirements for the foundation for tone pipes

Tona TEC and Tona Tec ISO systems are characterized by a lot of weight, due to the outer shell (blocks) made of porous concrete. Before installing modifications, you will need to make a foundation for the installation of clay-concrete blocks.
  1. The block sizes exceeded at least 20 cm.
  2. It was monolithic reinforced.

Tona Star and Tona San systems have a smaller weight, and therefore can be mounted on the support bracket. The need for the foundation is absent.

Rules for the organization of overlapping passage

The norms associated with the overlap passage are clearly stipulated in SNiP. In particular, there are safe distances from the chimney to the combustible materials. For pipes with double insulation, the minimum distance to the wooden surface will be at least 3 cm.

When installing one-way smoke removal systems, it will be necessary to increase the gap to 5 cm. The distance from the tree to the chimney is filled with non-flammable mineral insulation.

When installing through concrete platesThe gap for fire safety is not required. But, the diameter of the hole is expanded by several centimeters to facilitate installation and thermal expression.

Installing Tona chimney in wooden house Requires special caution. Pipes should not be closer than 1 meter from carrier structures.

How is the conclusion through the roof

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


Decoration chimney tone brand

The chimney Tona TEC and TONA TEC ISO is located in concrete blocks, from a light porous material exposed to moisture and dampness. To protect the design, it is necessary to bind the walls with ceramic tile or layer plaster.

Facing is performed using adhesive compositions intended for external work capable of withstanding heating and temperature fluctuations. The device of the ceramic chimney of tone in the bath may require additionally use the reinforcing grid when the framework is plastered.


Ensuring fire safety and eliminating the risk of carbon monoxide poisoning are the main tasks in the arrangement of the smoke removal channel. Most masters setting heating equipment, do not engage in pipe gasket, leaving these care to homeowner. Without experience and knowledge, it is difficult to figure out how to qualitatively mount the channel of smoke removal and understand which pipe to choose for the chimney. This article will tell how to make the right choice.

When it comes to the classic variant of the chimney pipe, first of all, the masters are called a brick option. The first furnaces and fireplaces invented by the person were supplied with smoke removal channels from this material. For the manufacture of the pipe, an burned outfit brick with high heat resistance is used.Brick chimneys Possess the following advantages:

  1. Aesthetics. The chimney pipe from the red chimney brick looks expensive, elegantly and presentable. She perfectly decorates the roofs of luxury mansions, cottages and modern town houses.
  2. Fire safety. Perhaps the main plus brick is that it protects other materials better from the occurrence of fires.
  3. High heat resistance. Brick is perfectly tolerated high temperaturewithout losing its operational properties. Brick chimneys can be used even for furnaces and fireplaces operating on solid fuel, in which the temperature of the outgoing gases is 500-700 degrees.
  4. Long service life. Well-laid brick tube serves at least 50 years old, and correct care And the service extends the "life" of the chimney to 100 years or more.

Important! Weighs a lot, so for the construction of the pipe from this material it is necessary to pour the foundation that is not associated with the main one. The cost of pouring concrete increases the cost of installation. The brick channel of smoke removal is the most expensive option, however, over time, these costs will pay off.

It is better to trust the experienced master from the brick, since a person without experience is difficult to choose the necessary diameter that supports the force of thrust necessary to maintain burning.

Ceramic chimney

Lately, chimney masters are actively implemented, differing from classic bricks. They are ceramic pipes up to 3 m long, light blocks with a hole are supplied with the complex with them, the diameter of which corresponds to their size. Compared to other materials, ceramics has the following advantages:

  • High heat resistance. Ceramic pipes "lock" the heat, emanating from a mixture of smoke with combustion products inside, without giving external blocks to heat up. Therefore, they are considered the most secure and reliable. Ceramics chimney does not require additional thermal insulation due to the high heat thermostability.
  • Resistance to moisture, corrosion and aggressive chemical compounds. Use ceramics for the structure of the chimney began, noticing how much it inert material. Pipes from it serve at least 50 years, without requiring special care.
  • Easy assembly. Set the chimney from ceramic pipes, in contrast to the brick, you can independently. The main thing is to correctly choose the diameter of the challenges you are going to use. For installation requires reinforcement bars and cement mortar.
  • Universality. Due to the variety of ceramic products, it is easy to choose the right diameter to connect to the introductory nozzle heating device. Therefore, chimneys from this material are used for all types of furnaces, fireplaces, gas boilers and boilers.
  • Ease of care. The inner surface of the ceramic pipe has a dense, smooth structure, which does not accumulate soot. The chimney of their ceramics is easy to maintain, as it does not require frequent cleaning.

Important! The weight of the ceramic chimney is slightly smaller than brick, however, he still has a significant burden, so it also requires a separate foundation separately. It is better to mount the smoke removal channel before the construction of the roof and start interior decoration. It is suitable if the channel configuration is strictly vertical. The complexity of this option is that after completion of the installation work, it is impossible to remake the pipe or increase its diameter.

Stainless steel chimneys

The most democratic variant of the smoke arrangement is the use of stainless steel pipes. The set for the assembly of the smoke removal canal consists of direct-like elements, swivel knees, tees, condensate and revision collections. Stainless steel chimneys convenient to use for self-assemblySince they do not require the fill of the foundation. Experienced masters I advise the following options:


Note! The cost of components for assembling the stainless steel smoke removal canal is lower than ceramic and bricks. Various types of pipes are perfectly combined with each other, so you can make combined channels. Single-mounted pipes are used for laying indoors, double-circuit - outside, and flexible - in places of pass through overlaps and turns.
