What pipe diameter is best to use for a bathhouse? Pipe for a bath: what material to choose from, how to install

Our ancestors heated baths exclusively in black. Inside the log house, in a simple hearth, a fire was lit and the stones were heated until they became red-hot. They also heated the water by dipping it into a container. There was no chimney, smoke came out through cracks and slightly open doors/windows, and a thick coating of soot remained on the walls and ceiling. They started steaming when the last firebrands burned out. Sometimes with a slight delay to allow carbon monoxide to escape. Nowadays, for steam procedures, stoves are used everywhere, water is supplied to the baths, a full floor and a dressing room are made, where the firebox door is often located. But the most important thing is that a chimney has appeared for the sauna stove, which serves to remove smoke. This is already a white bathhouse.

Functions and features of operation of a chimney in a bathhouse

The main purpose of a chimney in a steam room is high-quality and controlled removal of combustion products in order to completely eliminate the accumulation of harmful carbon dioxide and the formation of burning on surfaces. The resulting draft (with air suction into the combustion chamber) maintains a stable operation of the heat generator. By manipulating the flows, the user regulates the heating value of the furnace and fuel consumption. You can heat such a sauna stove for as long as you like, and you can steam all this time.

Important! The heater pipe gets very hot, so sometimes this energy is used to prepare water using tanks integrated into the design.

Features of heat distribution with different methods of connecting the heater to the chimney

The stove in the bathhouse is heated inconsistently. Accordingly, the smoke channel cools down completely between sessions, so the chimney parts experience the strongest repeated thermodynamic loads. The second important factor is operating temperature. Unlike boilers and furnaces used for heating, gases heated to 700 degrees or more are removed here. Direct-flow stoves are often used in the bathhouse; due to the lack of heating shields or water jackets that remove some of the heat, the smoke turns out to be so hot. Therefore, the problem of chimney burnout (the danger of gas contamination and fire) always remains relevant. Chimneys for bathhouse stoves are made from high-quality materials. If these are factory products, they must be approved by the manufacturer for such difficult operating conditions.

Important! The sauna stove pipes are routed through the ceilings or outside the building, along the facade. Having chosen the street version, which is easier to install, the channel is insulated along its entire length.

What materials are chimneys made from?

Brick pipe

Such chimneys are equally suitable for stone and metal stoves. For the main masonry, refractory bricks and clay-based mortar or a special “kiln mixture” are used. In the upper rows, facing materials and cement mortar are used.

Basic elements of a brick chimney

The smoke channel is plastered from the inside to close the seams and smooth out the planes - less soot and condensation will accumulate, and the draft will be better. The pipe configuration itself is no different; there are standard elements:

  • riser,
  • fluff,
  • otter,
  • neck,
  • head,
  • cap (deflector).

The main advantage of this solution is durability and high fire safety. However, a massive stone pipe needs time to warm up for stable traction.

Important! A brick chimney for metal stoves is not always a good option. It will not be possible to build it above the heat generator, so the channel is assembled nearby, the masonry is laid from the floor (foundation), and then the stove is connected to it with a horizontal transition.

Metal pipe

Steel chimneys are relatively lightweight, can be installed on top of a heat source, and are therefore well suited for factory-made heaters. The cross section is selected depending on the power of the furnace; you need to follow the manufacturer’s recommendations or focus on the diameter of the outlet pipe. Most often, chimneys for bathhouse stoves require a cross-section of 115 mm.

Water pipes made of ordinary ferrous metal can only be taken with a large wall thickness (from 5 mm), but they can still fail at any time (they burn out from high temperatures and rust from high humidity). Galvanized products also do not shine with durability, since the protective layer wears off very quickly.

Design and connection options for a sandwich channel

The only decent option is stainless steel. In principle, you can use a single pipe, well insulating it in the attic and outside, but a sandwich will perform better. These are complete chimneys consisting of small sections. A home craftsman can assemble a sandwich channel himself. Each element consists of two pipes of different sections, between which there is a thermal insulation filling. The line includes: a starting “single-wall” pipe for heat dissipation (sometimes with a water tank), main moldings about 1 meter long, transitions and bends, pass-through units for floors and roofing, inserts with dampers, top nozzles, deflectors.

When choosing a model for a sauna stove, you need to consider the following points:

  1. The wall thickness of the inner pipe should be maximum (from 0.8-1 mm),
  2. The grade of stainless steel must be resistant to temperatures of about 850 degrees, for example AISI 321 or AISI 439 and 409.
  3. The optimal thickness of basalt filling is from 50 mm (ideally 100 mm), and its density is from 120 kg/m3.
  4. We give preference to models with an outer pipe also made of stainless steel.

Important! The joints of metal pipes are positioned so that they do not fall into the cutting area and are visible.

Ceramic chimneys

Ceramic chimneys can withstand heat and are not afraid of moisture. They are a prefabricated multilayer structure, which provides everything necessary: ​​main linear blocks, inspection elements, containers for collecting and removing condensate (installed at the very bottom), cover plates, tees, ventilation grilles, upper mesh nozzles, etc.

Depending on the design, there are two types of products:

  1. Monolithic, self-supporting blocks, completely ready for masonry, with a through channel of circular cross-section. Between the inner cylindrical element and the outer flat casing there are bulkheads (stiffening ribs); they form chambers that play the role of a heat-insulating air layer and vertical ventilation ducts.
  2. Modular systems in which expanded clay concrete blocks perform the load-bearing functions, and smoke is discharged through a ceramic pipe located inside such a shaft. The block is placed on a cement-containing mortar, and the pipe from individual sections is assembled using sealant. Mineral wool is used to wrap a ceramic pipe like a sleeve.

Kit for making a ceramic chimney

Stoves and ceramic chimneys for baths are connected using a monopipe made of heat-resistant stainless steel. It is connected to the shaft from below or from the side. The installation diagram is selected depending on the technical conditions. The relatively light weight of the finished shaft allows for a mounted installation, although it is necessary to use support consoles or a brick base vault. If desired (for example, to free up space in the steam room), the root scheme can be implemented without any problems - the chimney is taken out into the dressing room or outside. To finish the chimney, use any suitable material (paint, flat stone, tile), having previously covered the blocks with cement slabs.

When choosing a chimney for your heater, do not forget that it will work in extreme conditions. Systems for conventional boilers and fireplaces cannot be used in this case. It is important to know and follow the installation technology, so it is advisable to invite experienced craftsmen to assemble the pipe.

A correctly selected bath pipe will help you avoid many troubles associated with problems in the operation of heating equipment. Neglecting the installation of chimneys can lead to dire consequences. To protect yourself from the danger of finding yourself in such a situation, when planning a chimney layout and choosing materials for its arrangement, follow the advice of experts.

To achieve the safety of your home, cottage or bathhouse, try to operate heating equipment correctly, and install chimneys strictly adhering to fire safety rules. The information below will be useful if you are planning to do such work.

Bath pipe installation

When setting up a bathhouse or sauna, it is necessary to provide thermal insulation for the walls and other structures adjacent to the firebox and chimney.

To do this, you can use non-flammable materials with thermal insulation properties:

  • basalt wool;
  • basalt wool cardboard.

Materials for thermal insulation that have a foil coating are also useful. For reliability, all insulation must also be sheathed with a layer of sheet metal. When choosing it, be guided, first of all, by your taste and financial capabilities.

Copper, stainless steel, or any other metal other than galvanized steel are suitable here. The use of galvanized metal is harmful to health: high temperatures promote the evaporation of zinc, and it can penetrate into the human lungs with air, causing negative reactions in the body.

You can additionally heat the steam room using the heat generated by the pipe in the bathhouse. To do this, the chimney is wrapped in a metal mesh filled with stones. Taking heat from the chimney, the stone then releases it into the steam room, which significantly increases the efficiency of the stove.

It would also be useful to use a combustion intensity regulator (cagla or damper). This will allow you to regulate the draft in the chimney, maintaining it at the desired level. In this case, the heat will not go outside, but will be used rationally. By adjusting the draft, they achieve such an intensity of firewood combustion that the temperature in the steam room will be 70-80 degrees.

Avoid completely blocking the chimney: this will lead to smoke in the room in which the stove is located.

Choosing a pipe for a bath

When installing a chimney in a bathhouse or sauna, you need to select especially heat-resistant materials. The pipe to the bathhouse for connecting the stove must be made of AISI 321 or AISI 409 stainless steel. The presence of titanium in the steel increases the heat resistance of this type.

In addition, titanium does not allow carbon to burn out and thereby prevents intercrystalline corrosion of stainless steel. made from these steel grades can withstand temperatures up to 750-850 degrees, maintaining all performance indicators.

The question often arises: how to make a pipe for a bath so that it safely passes through the walls and ceilings of the steam room? The use of sandwich chimney elements with additional passage sleeves that increase the thermal insulation properties will help here. It is important to arrange the chimney in such a way that all its joints are visible. It is strictly prohibited to place them inside a wall or inside a ceiling.

Since the temperature of the gases emanating from the stove in the bathhouse is very high, special requirements are placed on the chimney here: its thermal insulation layer must exceed five centimeters.

Remember also how to properly make an iron pipe for a bathhouse on a vertical section of the chimney. The steel grades mentioned above or other reliable materials are suitable here.

If there are ventilation ducts in the building installed during the construction process, it will be sufficient to use a single-wall chimney pipe. It is placed in the ventilation duct, and its walls will serve as thermal insulation for the resulting chimney. The installation work in a ventilation duct made in brickwork is called duct lining.

Parameters and location of pipes for a bath

The diameter of the pipe for a bath or sauna firebox is selected based on the instructions included with the stoves. Most often, the recommended chimney diameters are indicated there. In the absence of instructions, the diameter of the chimney is selected based on the size of the outlet chimney pipe of the stove.

The chimney of a bathhouse stove or sauna firebox must have a height also required by the instructions. If there are no instructions, then the height is taken to be more than 4.5 m. At the same time, make sure that the upper edge of the chimney is at or above the level of the wind support line.

Our bathhouse is associated with light steam and the pleasant crackling of wood in the stove, hot stones in the heater and the smell of a freshly brewed broom. But a live fire is associated with smoke, and if the chimney is not made correctly, you can get carbon monoxide poisoning in 20–30 minutes. The pipe in the bathhouse is planned before the construction of the bathhouse; it must be assembled efficiently and correctly. This is the only way the bathhouse will be safe and will not cause harm to its owners. We will tell our readers how to remove a pipe in a bathhouse with your own hands, what features and subtleties you need to know.

The pipe in the bathhouse is removed in two ways: inside and outside the structure.

Planning a chimney in a bathhouse is always associated with the choice of design. It is necessary to understand all types, know how to correctly calculate the size, display and install. Before drawing up the project, it is necessary to briefly study these aspects.

What pipes are used for baths?

The chimney in a bathhouse can have two devices: external and internal. Each has its positive and negative sides:

  1. External arrangement is less fire hazardous, do-it-yourself installation and fastening is also easier. The disadvantages are that the pipe goes outside and heat loss increases.
  2. The interior arrangement is complex, but all the heat gets into the bathhouse. The main disadvantage is a high degree of fire hazard.
The sandwich pipe is easy to install with your own hands.

Design flaws can be prevented by using high-quality insulation. We advise you not to save on time and effort and install an internal chimney; although it is more difficult to install, it will reduce the cost of heating the steam room structure. For a small bathhouse in a summer cottage, it is easier to remove the external chimney. In any case, the choice is up to the user.

Various materials are used for the chimney: red brick, ceramics or metal. They withstand temperatures above +100 °C and are durable.

It’s easier to buy a ready-made sandwich chimney. It is easy to assemble and install, and the internal asbestos lining makes the device safe.

Design of external and internal chimneys

The design of the chimney is selected depending on the characteristics of the selected stove. The pipe package includes several components, each with its own functional features. For a bathhouse with a brick stove, you can use brick, metal, ceramics, and for a metal stove - a ceramic or metal chimney. You can use brick, but laying the pipe yourself will be difficult. You will have to hire a bricklayer - a stove maker.

The main components of the chimney (design lists start from top to bottom):

  1. Head (probe) - prevents sparks from hitting the roof and neighboring buildings, as well as from flooding during rain.
  2. Master flush.
  3. PPU (Ceiling assembly where it goes through).
  4. Chimney made of double sandwich or brick.
  5. Single iron pipe.

When choosing a brick structure, you need to be prepared for complex cleaning and maintenance. A massive foundation is needed for the stove, since a brick chimney weighs a lot, and the entire load will fall on the stove.

A simpler assembly that does not require special knowledge is a ready-made structure made from sandwich pipes. It consists of a double structure between which asbestos is laid. More heat-saving and lighter. They are made up of individual elements: elbow, deflectors, tees, rain protection, adapters and gate. Fastened using brackets that are mounted with clamps.

What to pay attention to during installation

It is necessary to remove a pipe in a bath taking into account a number of its features (material, design). The installation is influenced by sanitary and environmental standards, the material from which the bathhouse was built. Do not forget that traditionally this is a tree.

Compliance with certain rules and regulations will make the structure reliable and safe:

  1. Any one must be insulated with environmentally friendly and non-flammable material: expanded clay, asbestos, stone wool.
  2. Thermal insulation of the place where the chimney passes is necessary only with foil material. It is often confused with materials covered with Dacron foil, but it is highly flammable and melts at temperatures above 300 °C.
  3. The chimney is installed so that the structure does not touch any wooden elements: floor beams, roof, walls. To insulate the joints, they are sheathed with metal sheets. The outlet area can only be insulated with non-flammable mineral wool or expanded clay mound.
  4. Inside the ceilings, you need to install a special iron box, into which the structure is placed and covered with expanded clay. There is no need to make a box for the sandwich.
  5. On top, to avoid contact with the roof, a casing of metal sheets is made around it.
  6. All joints and seams can be sealed with special iron foil tape or foil.

How to choose the size and shape of a chimney

Diagram of the pipe outlet in the bathhouse.

When designing a chimney in a bathhouse, you need to adhere to the standard shape and size. The best option is a cylindrical shape. The simple shape is due to the fact that any bend in the elbow will additionally create areas for the accumulation of ash and soot; the structure will have to be cleaned frequently. And cleaning a structure with numerous bends is more difficult.

The main dimensions that need to be determined are the diameter and height of the structure. They must be taken from SNiP.

Bath pipe diameter

The power and choice of stove are directly related to the choice of diameter and height of the chimney. Here are some values ​​for a rectangular and square chimney in the form of a table:

Furnace power, kW Chimney diameter, mm
Up to 3.5 140x140
3,5–5,2 140x200
5,2–7,2 140x270

For a round stove, the diameter of the chimney is taken equal to or greater than the outlet of the stove. In order to calculate the diameter, you need to know the formula, which stipulates that for 1 kW of stove power, take at least 8 m2 of pipe. So, for a 20 kW stove, the chimney area will be at least 160 m2. It is at least 14 cm in diameter.

Bathhouse chimney height

The height is calculated depending on the type and height of the roof ridge. Neighboring buildings must also be taken into account, especially if the bathhouse is attached to the main house. According to SNiP, the height of the bath chimney must correspond to the indicators indicated in the table:

For a flat roof, the height of the bathhouse chimney must be at least 1 m. For a high pipe (more than 1.5 m), it is necessary to install special guys, they will strengthen the structure.

It is important to take into account the moment of the sloping and horizontal elements of the chimney. A length of more than 1 m is unacceptable. The permissible size will prevent soot from accumulating on the walls of the bathhouse pipe and will not interfere with traction.

DIY chimney installation

Before work, you must purchase all the necessary materials and components. All work takes place in stages: preparing holes for the pipe outlet, installing a protective box, assembling the pipe.

Preparing holes for pipe output

Do not install a pipe with too many bends.

It is better to make holes in a new bathhouse under construction at the stage of assembling the floors and roof. In an already assembled structure, you will have to do it from scratch. If installation is chosen inside the bathhouse, then holes are cut out in the ceiling and roof; the external one includes one in the wall near the bathhouse stove.

The holes must be sheathed on both sides with sheets of metal 0.5 mm thick. They will protect the surface from fire. The holes are made with a square section of 450x450 mm. Dimensions depend on the sandwich pipe adapter. For a brick chimney, the size of the hole must be equal to the specified width of the chimney masonry. More information about how to properly make a hole in the ceiling of a bathhouse is described in the video:

Manufacturing and installation of a protective box

Factory-made protective box for a sandwich pipe.

You can make an adapter for a metal and sandwich pipe with your own hands: Take 2 metal sheets measuring 50x50 cm and cut out an outlet for the pipe in the middle. A box is made from 4 sheets, which is connected by welding. The box is insulated with stone or basalt mineral wool and covered with metal foil. A pipe will be inserted into it, it will protect the ceilings from heating.

Next, attach a metal protective apron to the roof. You can buy it ready-made “Flash Master”. The box is installed in place between the ceiling transitions and screwed with screws. There is no need to make a metal protective box for a brick pipe. Next, a chimney is installed.

Installation of a chimney

The assembly of the pipe in the bathhouse must be completed by installing an anti-rain fungus.

To attach the pipe, you need to drill places for fastenings opposite the chimney outlet hole. The sandwich pipe is made in such a way that all parts are simply installed into each other.

First, the first link from the stove, 50 cm long, is mounted. It is fixed into the prepared holes using metal fasteners to the wall and the stove. Next, the second link is brought out into a metal box. If the diameter of the second link is smaller than the outlet of the first, then use a special adapter.

Having installed the second link, the box is filled with expanded clay into the adapter. If the stove is not located strictly under the hole in the ceiling, then use an elbow. You should not use more than three elbows in one pipe design; soot and soot will accumulate in the bathhouse pipe.

A fungus is mounted on top of the pipe; you can make it yourself from a sheet of metal or an old tin can. It's easier to buy ready-made.

The outer pipe is assembled with one difference: first the elbow is mounted to the wall and only then the main structure. A transition box, insulated and filled with expanded clay, is placed in the wall in the same way. The main pipe goes out from the box to the street. On the outside of the bathhouse, a tee is attached to the pipe, where an inspection with a window is located. They will help clean the building from soot. All parts of the pipe from the outside are attached to the wall in stages. On the façade of the bathhouse you can only use a double sandwich structure, and only a single one on top of the roof. The wall under the pipe is insulated with metal or asbestos material.

There is no need to rush to assemble the pipe; it is better to carefully secure each link. How fireproof the bathhouse will be depends on how well the bathhouse pipe is installed. The safety of not only the wooden walls and passages of the bathhouse, but also the safety of the people who will use the building is important. You should not skimp on insulation; it is better to make it high quality from expensive material. This is the only way the steam will be light and the sauna safe.

You should pay quite a lot of attention to the selection of pipes for the bath. The fire safety of the steam room, as well as the difficulty of maintenance and microclimate characteristics, and much more, depend on the correct choice of material. Let's consider all the features of this issue in more detail.

Types of pipes for baths

When making pipes for a steam room, a variety of materials can be used:

  1. Black metal.
  2. Ceramics.
  3. Asbestos-cement building.
  4. Brickwork.
  5. Stainless steel.
  6. Sandwich panels.

Each variety has its own characteristics, which we will discuss later.

Ferrous metal pipes

Ferrous metal is used extremely often in the manufacture of pipes. The main advantage is its low cost. It should be borne in mind that compared to brickwork, ferrous metal pipes are approximately 80% cheaper. However, it is worth considering a fairly large number of disadvantages:

  1. Heavy weight. Ferrous metal pipes, as a rule, are quite heavy. Therefore, the work of attaching it becomes significantly more complicated.
  2. High fire hazard. The walls of steel pipes heat up in a short time to a fairly high temperature. As a result, surrounding materials may heat up and catch fire.
  3. Fragility of the structure due to corrosion instability. As is well known, metals are susceptible to water, resulting in corrosion on the surface. Because of this, the metal begins to rot and the strength is significantly reduced.

In addition, do not forget that when the furnace heats up, a fairly large amount of condensate can form on the pipe. Such a system has many more disadvantages than advantages. However, one positive side often becomes decisive - if you need to save money, then ferrous metal pipes are more suitable than other materials.

Asbestos cement pipes

Asbestos pipes have recently been used extremely often. It is produced on the basis of asbestos, which is a non-flammable silicate mineral. Among the main advantages are corrosion resistance. At the same time, in comparison with brickwork, asbestos-cement construction is much cheaper. However, there are several significant disadvantages:

  1. Due to a significant decrease in the heat capacity, the thrust indicator decreases. As a result, smoke may escape from the stove into the room.
  2. A fairly large amount of condensation is released on the surface of the product.
  3. Design features determine the inability to install in an inclined position.
  4. It is impossible to create hatches through which soot can be cleaned from the structure.
  5. The pipe cannot be used at high temperatures. It is worth considering the fact that at temperatures above 360 ​​degrees Celsius, the material begins to crack and break.

It should be remembered that the material in question can release harmful substances when heated strongly. An asbestos-cement structure can be called a fairly economical proposal that cannot last long. If there is a need to save money, then pipes made from this material are quite a profitable and reasonable solution.

The use of bricks in the construction of masonry

A traditional chimney option is brickwork. The peculiarity of this design is the need to erect the structure at the time of construction of the structure itself. Most often, brickwork has a rectangular shape, which determines the accumulation of soot in the corners. It is possible to create a round shape, but when carrying out such work, serious difficulties arise. The advantages include:

  1. High temperature resistance.
  2. The design provides additional heat transfer, which reduces the likelihood of condensation.
  3. Quite an attractive appearance.
  4. High reliability and resistance to environmental influences.

But there are several significant disadvantages:

  1. The construction of such a structure requires very large funds.
  2. Due to the high porosity of the surface, a very large amount of soot accumulates on it. This is why serious cleaning problems arise.
  3. Heavy weight. When considering brickwork, one should take into account the fact that the structure exerts very high pressure. That is why a solid foundation must be created under the stove and the chimney itself.
  4. Due to exposure to soot and other combustion products, as well as high humidity, low-quality material is destroyed. If the construction technology of a structure is violated, it can collapse very quickly.

In addition, do not forget that strong vortex flows form in the corners, resulting in serious problems with traction. Many people solve most masonry problems by installing stainless steel pipe inside the masonry.

Stainless steel pipes

There are quite a few reasons why condensation occurs on the inner or outer surface of pipes. This is why some experts recommend using stainless steel as the main material when making pipes. This type of metal is highly resistant to weathering and can last for quite a long period. Among the main advantages we note:

  1. The structure is lightweight, which means there is no need to build a special foundation.
  2. Due to the increased resistance to high humidity, the design has a long service life.
  3. The inner surface is smooth, which means there is no chance of plaque accumulation.
  4. Ease of installation work.
  5. Stainless steel pipe can be installed at the time of construction of the structure or after completion of this work.

In addition, we will pay attention to the reasonable cost of this material.

However, there are several disadvantages, among which we note:

  1. There is a need to carry out insulation work on the outside. Otherwise, the temperature difference causes the formation of a large amount of condensation.
  2. In some cases, stainless steel does not suit the design style of the building.

If desired, you can decorate the pipe using a special casing that imitates brickwork or other finishing material.

Ceramics

For many years, ceramics have been used as the main material. This is due to the fact that this material can withstand high temperatures. Quite often, the finished structure is closed in a special casing. The advantages of ceramic construction include the following points:

  1. The material accumulates heat well. Ceramics heats up well and also retains heat for a long period.
  2. Ceramics tolerate temperature changes. This material can withstand several cycles of heating and sudden cooling without changing the structure. This property of ceramics has been known for many years.
  3. High humidity and chemicals are not corrosive.
  4. High degree of versatility. Ceramic pipes are suitable for a wide variety of furnaces and structures.
  5. All surfaces are smooth, which reduces the likelihood of soot formation.
  6. The structure is practically not affected by condensation.

However, there are certain disadvantages, among which we note the large weight of the structure. That is why it is necessary to create additional fastening elements. Many experts point out that the difficulties in performing installation work are completely worth it.

In addition, do not forget that ceramics is very fragile and is susceptible to strong impacts. That is why in many cases special protective covers are used.

Sandwich panels

A modern building material can be called sandwich panels. Their features are as follows:

  1. The structure is multilayer, which determines the greater thickness. It became possible to produce this type of material only with the advent of modern technologies.
  2. Each layer is responsible for specific functions. An example is that there are insulating materials on the outside, stronger ones on the inside that can withstand significant loads.
  3. The cost of sandwich panels is very high. This is due to the high complexity of production of sandwich panels, as well as the use of a fairly large amount of expensive materials.
  4. When creating a chimney, technology must be followed, otherwise the design will not have the proper performance qualities.

In addition, you should take into account the durability of the chimney - many manufacturers guarantee a service life of more than 10 years.

Features of installation work

There are quite a few features regarding installation work that need to be taken into account. An example is the information below:

  1. To begin with, a hole is created for the chimney of the appropriate diameter.
  2. A metal apron is being installed.
  3. After completing the preparatory stage, the installation of the chimney itself is carried out. To begin with, the fastenings are prepared in increments of about 20 centimeters.
  4. The structure is assembled, after which the pipe is connected to the furnace.
  5. The damper is installed.
  6. The last structural element to be installed is the outer part of the pipe, rising above the roof.
  7. Experts recommend securing protective bends that will prevent precipitation from getting inside the oven.

In general, we can say that there are no special problems when performing this work. When carrying out installation work, attention should be paid to insulating the pipe from external materials, which ignite when heated strongly.

In conclusion, we note that before carrying out the work, the development of an appropriate project should be carried out. Also, to implement the project you will need a variety of tools, as well as assistance, since lifting the pipe and other work is difficult to do alone.

Previously, sauna stoves did not have a chimney. Then the ancestors of modern people washed themselves in black. Today there is no longer any need to inhale and there is no soot - all this is true, because modern baths are created according to new design laws. Mostly people build steam rooms on their own. You should also build a stove and a chimney for the bathhouse. But we must remember that this is a very responsible matter that requires a serious approach. You can accidentally make one small mistake, and the steam room will not work as intended. Therefore, it is very important to work without haste and extremely carefully.

Types of smoke exhaust structures

The chimney for a steam room can be external or internal. In our country, you can often find internal options. Among their advantages is the absence of violation of the architectural style, as well as saving heat in the room.

All the heat remains inside the steam room. Internal systems are good because they have better traction. They are also easier to care for. The internal structure also does not require insulation.

The external systems are more like American traditional chimneys. They were previously used by Americans on their ranches. They have a rather interesting appearance. If you decide to build an external solution, then there is no need to make a hole in the roof and ceiling, which definitely has advantages. The wall for the chimney inside must be no less than 12 cm thick, and for the outer wall the thickness must be at least 38 cm.

Popular schemes for installing sauna chimneys

How is the smoke exit structure arranged? Any element is a structure made of pipes, flanges, and fasteners. The main requirement for this building is the ability to operate at high temperatures without any changes in the properties and emissions of combustion products.

To prevent the chimney for a bathhouse from losing large amounts of heat, it is located as close as possible to the inner wall.

In this case, you will get the most effective traction. And if there are reasons why this configuration is impossible, then a thicker wall is created.

Thickness parameters depend on temperature. For example, if the temperature is lower than 20°, then it is necessary to make thick walls, from 38 cm. If there are severe Russian frosts in the region, then the thickness should be about 58-65 cm.

When there is more than one stove in a steam room or bathhouse, then each of them must be equipped with its own chimney. Otherwise, the traction will lose strength. Smoke exhaust system specialists recommend the following. In cases where it is impossible to build several systems for stoves, a cutting system must be installed at a height of approximately 75 cm. It is also important to ensure that the inner surface of the future chimney is as smooth as possible. If there are any roughness inside, soot will accumulate on the walls. This may increase the risk of fire.

The simplest chimney

This element will be based on a stainless steel pipe. In addition to this, you need to prepare one elbow with a diameter of 20x120 cm from galvanized steel, two elbows of 16x120 cm each, three of stainless steel of 16x10 cm each. You will also need a tee with a diameter of 16 cm and a plug for it. You also need a fungus that is the right size. The diameter of the chimney for the bathhouse in this particular case will be 16 cm.

The prepared pipes should be connected to each other using self-tapping screws.

It is necessary to make a hole in the ceiling slab, the diameter of which will be 16 cm. Next, from the roof surface it is necessary to remove the soft roof and thermal insulation 15 cm from the hole made.

The section of pipe that will be outside is wrapped with basalt wool. The layer should be approximately 16 cm. You should also additionally wrap the cotton wool with asbestos cord. Then a pipe with a diameter of 20 cm is connected, which is fixed and thoroughly coated with bitumen mastic. An asbestos cord is placed in the gap between the two pipes. This is necessary for protection from rain.

This is how you can independently design and install stainless chimneys for a bathhouse. This is a very affordable solution.

Features for different types of ovens

Modern equipment for baths is equipped with brick smoke removal systems.

Pipes made of ordinary or stainless steel are also used. Each material has advantages and disadvantages, and there are also certain nuances in installation.

After the installation of the stove is completed, you can immediately begin installing the chimney. The first step is to attach several expansion supports to the pipe. It’s good if these are pipes made of asbestos or “Sandwich”. The latter can withstand significantly higher temperatures, unlike other analogues. However, such a pipe should not be exposed to direct flame. That is why a steel pipe is installed first, and then, after the first bend, a sandwich or asbestos-cement structure is installed.

Now all that remains is to organize the protection of the upper part from the rain. A plug may be suitable for this. Another one is mounted on the pipe below, which will then facilitate the process of draining condensate and cleaning.

If the oven is brick

This chimney for a bathhouse is easy to build with your own hands. When the row of masonry covers the stove, the construction of the chimney system begins.

So, on the 21st row of brickwork it is necessary to form two channels. They will then be merged. Next, on the right you should block the space above the core. The gap between the core and the masonry will be 2-3 cm. Any voids are filled with mineral wool insulation. With the 22nd row of masonry, the opening will already be closed, and after that you can begin to lay and shift the channels to the middle. To prevent this ceiling from cracking in the future, it is advisable to lay another row of masonry above the stove core.

For those who managed to build a brick oven, making a chimney will not be difficult. The main thing is that no cracks arise. Also, the standard for the cross-section of the pipe should not be exceeded. Otherwise, the gases will cool quickly.

How to make a chimney for a bath through the ceiling

They are often built from pine. This wood sometimes overheats. The process of smoke passage must be created with maximum attention. The wall must be fenced with any non-combustible materials. You can strip steel sheets; mineral wool or brickwork will also work.

Another effective method of protection is a special ceiling-passage assembly.

To do this, holes are cut in the ceiling where this very box will be installed. After this operation, a pipe is pulled through the assembly. It, in turn, must be insulated on each side.

At the next stage, the pipe is erected above the roof. Its height should be at least 1.5 m. When it passes through the roof covering, it is necessary to apply a sealing cover. Using this operation, you can hermetically connect the chimney pipes.

In order to get good traction and long service life, you need to clean the pipe from accumulated soot and debris once every six months. And then the bathhouse will delight its owner for a very long time.

Bath pipes

The chimney plays a very important role in creating a comfortable microclimate. The choice of pipe material for it is also important. The pipe is not only a smoke exhaust system, but also safety in case of fire, as well as health. Let's find out which chimneys are best for a bathhouse.

The pipe in the steam room can be made from a variety of materials. However, it is best to use stainless steel for this. This material has a lot of important characteristics, such as resistance to high temperatures, light weight, ease of use, good traction, and resistance to aggressive environments. The best chimney for a bathhouse is made of stainless steel.

Asbestos cement pipes are not very desirable. They poorly comply with fire safety standards.

When exposed to high temperatures, a product made of this material may collapse and a fire may occur, which is very dangerous in a steam room with wooden walls. This is a rather dubious saving.

Ceramics are reliable and durable. Such chimneys can withstand high temperatures up to 600 degrees. But these pipes are also poorly suited for a bathhouse. It's all due to the heavy weight. They are definitely not suitable for wooden structures.

Sandwich

This is a modern option. Chimneys for wood-burning saunas are assembled from it.

This product consists of two pipes. Non-combustible insulation is provided between them. Modern materials are used as it, such as basalt or ceramic wool, vermiculite. The smaller pipe serves as a chimney outlet. The big one is the outer casing. Its task is to keep the insulation dry. The casing can be made of galvanized or stainless steel.

These are the types that exist, and anyone can make such a design with their own hands.
