Previously, bath stoves did not include a chimney. Then the ancestors of modern people washed in black. Today there is no longer any need to inhale carbon monoxide, soot is also absent - all this is so, because modern baths are created according to new design laws. Mostly people build doubles on their own. You should also build a stove and build a chimney for the bath. 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 the steam room can be external or internal. In our country, you can often find exactly the domestic options. Among their advantages are the absence of a violation of the architectural style, as well as the saving of 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. Still the internal design does not need insulation.
External systems are rather American traditional chimneys. They were previously used by the Americans on their ranches. They differ in 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 should be no less than 12 cm in thickness, and for the outer wall the thickness should be between 38 cm.
Popular schemes for the installation of bath chimneys
How is the smoke exhaust structure designed? Any element is a construction of pipes, flanges, 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.
So that the chimney for the bath does not lose large volumes of heat, it is placed in the maximum proximity to the inner wall.
In this case, you get the most effective traction. And if there are reasons why this configuration is not possible, then create a thicker wall.
Thickness parameters are temperature dependent. For example, if the temperature is lower than 20 °, then it is necessary to make thick, from 38 cm, walls. 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 the steam room or bath, then each of them must be equipped with its own chimney. Otherwise, the thrust will lose force. Specialists in flue systems recommend the following. In cases where it is not possible to build several systems for furnaces, it is necessary to equip a dissection system at a height of about 75 cm. It is also important to consider that the inner surface of the future chimney is as smooth as possible. If there are any roughness inside, then soot will accumulate on the walls. This may increase the risk of fire.
The easiest chimney
At the heart of this element will be a stainless steel pipe. And besides it, you need to prepare one elbow with a diameter of 20x120 cm from galvanized steel, two elbows of 16x120 cm, three of stainless steel of 16x10 cm. You will also need a tee with a diameter of 16 cm and a cap for it. A suitable size fungus is also needed. The diameter of the chimney for the bath specifically in this case will be 16 cm.
Prepared pipes should be connected to each other using self-tapping screws.
A hole must be made in the ceiling plate, the diameter of which will be 16 cm. Next, the soft roof and thermal insulation must be removed from the roof surface 15 cm from the hole made.
That piece of pipe that will be outside is wrapped with basalt cotton wool. The layer should be about 16 cm. Also, you should additionally wrap the cotton wool with asbestos cord. Then a pipe with a diameter of 20 cm is connected, which is fixed and carefully lubricated with bitumen mastic. In the gap that has turned out between the two pipes, a cord of asbestos is laid. This is necessary to protect from rain.
This is how you can independently design and install stainless steel chimneys for a bath. This is a very affordable solution.
Features of the installation of chimneys for various types of furnaces
Modern equipment for baths is equipped with smoke exhaust systems made of bricks.
Pipes from ordinary or stainless steel are also used. Each material has advantages and disadvantages, and there are also certain nuances in the installation.
Installation of chimneys for a bath for a metal furnace
After the installation of the furnace is completed, you can immediately begin to equip the chimney. First of all, it is necessary to attach several expansion supports to the pipe. It’s good if it will be asbestos pipes or Sandwich. The latter can withstand significantly higher temperatures, unlike other analogues. However, do not allow exposure to such a direct flame pipe. That is why, first, a steel pipe is mounted, and then, after the first bend, there is a sandwich or a construction made of asbestos cement.
Now it remains only to organize the protection of the upper part from the rain. A stub may be suitable for this. From below, another is mounted on the pipe, which will then facilitate the process of condensate drainage and cleaning.
If the brick oven
This chimney for a bath is easy to build with your own hands. When a row of masonry blocks the furnace, the construction of the chimney system begins.
So, on the 21st row of brickwork, two channels must be formed. Then they will be combined. Next - on the right should overlap the space above the core. The clearance between the core and the masonry will be 2-3 cm. Any voids are filled with mineral wool insulation. With 22 near the 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 overlap from cracking in the future, it is advisable to lay another row of masonry over the core of the furnace.
Next - the chimney will begin to narrow. Here valves are installed. They are made one above the other. Now the brickwork will go to the edge.
For those who managed to build a brick oven, making a chimney is not difficult. The main thing is that there should not be any cracks. Also, the norm for the cross section of the pipe should not be exceeded. Otherwise, the gases will cool rapidly.
How to make a chimney for a bath through the ceiling
Often, modern baths are built from pine. This wood is sometimes overheated. The process of passing smoke should be created with the utmost attention. The wall should be fenced with any non-combustible materials. You can strip steel sheets, mineral wool or brickwork is still suitable.
Another effective way of protection is a special ceiling-through unit.
To do this, cut holes in the ceiling where this box will be installed. After this operation, a pipe is pulled through the assembly. She, in turn, must be insulated on each side.
In the next step, the pipe is built over the roof. Its height should be at least 1.5 m. When it passes through the roof covering, it is necessary to apply a cover-seal. With this operation, you can tightly connect the chimney pipes.
In order to get good traction and a long service life, you need to clean the pipe from accumulated soot and debris once every six months. And then the bath will delight its owner for a very long time.
Pipes for the bath
In the creation of a comfortable microclimate, the chimney plays a very important role. The choice of pipe material for it is also important. A pipe is not only a chimney system, but also safety in case of fire, as well as health. Let's find out which chimneys are better for a bath.
The steam room pipe can be made from a wide 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, low weight, ease of use, good traction, resistance to aggressive environments. The best chimney for a bath 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 will occur, which is very dangerous in the steam room, where the walls are made of wood. This is a rather dubious saving.
Ceramics is reliability and durability. Such chimneys are able to withstand high temperatures up to 600 degrees. But these pipes are also poorly suited for a bath. The reason for this is a lot of weight. They are definitely not suitable for wooden structures.
Sandwich
This is a modern option. From it collect chimneys for a wood bath.
This product consists of two pipes. Between them non-combustible insulation is provided. As it is used modern materials, such as basalt or ceramic wool, vermiculite. A smaller pipe serves as a chimney. Big is the outer casing. Its task is to keep the insulation dry. The casing can be galvanized or stainless steel.
These are the types of chimneys for bath stoves, and everyone can make such a design with their own hands.
