Chimneys for a bath: device, installation, cleaning of an important component of a bathhouse

Chimneys for a bath

If you decide to build a bathhouse, you should carefully calculate and analyze all the consumables, and also properly install the chimney duct, since any room of this type requires the utilization of exhaust gases. The importance of the system is associated with a comfortable stay in the steam room and with human health. That’s why you need to know how to properly install the chimneys for the bath.

    The chimney is designed to remove smoke from the bath, which is formed during the combustion of fuel. Chimneys in the bathhouse supply oxygen to the furnace due to draft to ensure and maintain combustion.

    The correct layout and installation of the chimney in the bath is a very important point in the structure of the steam room. Owners often face a problem when, due to inappropriate material, incorrect calculation of the cross-section and the height of the channel, a general smoke in the room, back draft or fires occur. Therefore, when installing the chimney, it is worth remembering the fire safety rules!

    Errors that are associated with improper installation of the chimney can reduce its efficiency by up to 60%. Do not build a chimney for a bath with your own hands just as if, its device must meet several requirements.

    Therefore, you need to consider the main principles of the proper removal of combustion products:

    • A cylinder is an ideal form for a chimney, because there are local swirls in square pipes that are harder to clean.
    • The diameter of the channel must be determined based on the number of turns in the chimney and its height.
    • The chimney must be installed higher than 0.5 meters above the upper point of the bath, that is, the product should be located above the space of the wind support.
    • If the chimney device has right angles, then ideally the length of the horizontal sections should not exceed half a meter or should be minimal.
    • After a right angle, it is recommended to install a tee with a revision to ensure that the chimney can be cleaned.
    • The pipe that runs along the street must be thermally insulated, in other words – insulated.
    • The design of the chimney for the bath suggests that its vertical part should always be collected by expanding upstream of the condensate.

    Material for flue system

    The material from which the chimneys are made must be resistant to corrosion and adapted to the constant influence of flue gases, which are characterized by high temperature. Chimneys in the bath must withstand the effects of aggressive acid and condensate.

    If the bath is built of wood, you need to be extremely careful! Dry wood can smolder at 100 degrees Celsius. In this situation, special attention should be paid to the installation of the chimney in the bathhouse and the implementation of fire safety rules. It is forbidden to use pipes made of aluminum or galvanized steel as elements to the chimney, because such elements are used only for ventilation.

    The most affordable and versatile material to date is stainless steel, which is acid and heat resistant. For the manufacture of components for the chimney, it is customary to use a special grade of steel containing molybdenum, it is this substance that makes the chimney in the bath durable and reliable.

    Chimneys made of acid-resistant steel do not require the construction of a foundation, because they are lightweight and are mounted on the wall. Soot and soot do not settle on the smooth and even walls of the metal chimney. The steel chimney is mounted with ease in an already built bathhouse, in which the construction of a brick chimney was not provided in advance.

    A brick chimney in a bathhouse takes up a lot of space, so only owners of large steam rooms can afford to install such a channel. Such a chimney is carried out by simple brickwork. In addition, the installation of the chimney requires the presence of heat-resistant materials and the presence of filters, which serve to clean the smoke from harmful impurities.

    Construction of the chimney in the bath

    If you decide to create a steam room to spend time there during the cold winter season, it is worth learning, first of all, how to make a chimney in the bathhouse correctly. Walls and structures, which are located close to the chimney and firebox in the bath, require thermal insulation. To do this, use non-combustible materials such as basalt wool and cardboard, made of basalt wool. It is advisable to choose thermally insulating materials that differ in foil coating..

    From above, the walls are sheathed with metal sheets – copper sheet, stainless steel sheet or other material. It all depends on the financial capabilities and preferences of the owner.

    But galvanized metal is not recommended as a sheet, because zinc evaporates when heated and enters the lungs with air, negatively affecting the human body. Also suitable brick, tile, natural or artificial stone, along with a special stove solution.

    The first chimney element that fits into the firebox must be internally treated with a furnace sealant. The outer contour of the structure is better to rivet. All pipes should be connected along the condensate – the upper pipe in the inner loop enters the bottom.

    The procedure for fixing the chimney in the bath is very important. It is always worth considering that the weight of the pipes should be on unloading platforms and mounting brackets that are used on floors. The clamp should compress the external contour and fasten to the wall with a plastic dowel and a metal screw. Now you know how to install a chimney in a bathhouse!

    The excess heat generated by the chimney can be used to heat the steam room. A fairly effective solution is to install special chimney elements that additionally remove heat from the pipe.

    Often, the efficiency of the stove is increased by using a metal mesh into which the stones are placed. They envelop the chimney and heat up, giving even more heat to the bath. Also relevant is the installation of a combustion intensity controller – cahly. Fans of wet steam should buy a pipe with a tank for the formation of wet steam.

    Cleaning, service rules

    Clogging of the chimney duct in the steam room provokes a decrease in draft in the furnace and even its complete cessation. Therefore, it is important to know how to clean the chimney in the bathhouse! If the pipe is straight, it is worth sinking the stove with aspen. Experts recommend making every last bookmark aspen wood. Potato peeling also helps – starch reacts with soot, and the latter burns out.

    For cleaning chimneys with a complex configuration and many channels, you can use a special ramrod, which consists of a metal cable, at the end of which is located a brush on the end. In the construction markets you can find special briquettes for cleaning chimneys.

    Thus, each person knows that a real Russian bath brings unthinkable pleasure. Many of the visitors to the steam room think about building such an institution at home. To feel light after bathing, you need to build a bathhouse in accordance with all the rules, which include recommendations for installing a chimney channel. Choosing the right material for the chimney, having stood all the necessary distances and fire standards, you can safely enjoy water procedures.
