Types of chimneys

According to the type of material of manufacture, chimneys are divided into ceramic, metal and brick . Also, the chimney is made of composite materials and has a multi-layer structure.

Choose a chimney modification that more closely matches your home.

The cheapest and most common option is the metal chimney . It is ideal for heating baths or non-residential premises. This economical approach is not advisable for installing a chimney in a private house. Metal structures have poor joint sealing, making it difficult to get rid of smoke in the room. The installation of a metal chimney is not advisable, since they have a short service life and are not resistant to moisture.

Do-it-yourself installation of a chimney through the roof and wall in a wooden house? Step by step instructions + Video Chimneys made of composite multilayer metals are more reliable and resistant to aging. A special fire-resistant material is placed between the layers of this pipe. Many manufacturers, deciding to save money, place low-quality material in intermediate layers, which begins to crumble over time. Therefore, when buying this pipe, carefully study the manufacturer's company.

The cheapest way is to build a chimney made of thin stainless steel .

The low weight of this pipe allows it to be fixed with minimal fixing material. In addition, stainless steel pipes are easy to process - they can be cut with ordinary metal scissors. Installation of stainless steel chimneys is perfect for private houses.

Do-it-yourself installation of a chimney through the roof and wall in a wooden house? Step by step instructions + Video Ceramic chimneys are very complex in the device, since their installation is carried out together with the whole house ..

. Therefore, they are rarely used, because in order to build them in a finished house, builders will need to partially dismantle the floors.

To install a chimney with your own hands in a residential building, you will need the following tools:

  • grinder for metal;
  • drill for drilling holes;
  • chisel and spatula;
  • electric jigsaw and screwdriver;
  • Phillips screwdriver and hammer;
  • safety glasses and gloves.

Important points when installing a chimney with your own hands

Depending on the construction method, all chimneys can be divided into two main groups: internal and outdoor. Below, we will consider in more detail in which cases one or another option is chosen.

Do-it-yourself installation of a chimney through the roof and wall in a wooden house? Step by step instructions + Video The internal structure of the chimney is used for the construction of heating systems based on heating boilers or fireplaces ... These systems are usually installed inside walls. After the installation is complete, the chimneys are closed in the thickness of the wall and decorated.

The advantages of this system are that it is not susceptible to condensation and is perfectly protected from atmospheric moisture.

The combustion products passing through the chimney are hot. And the section of the wall passing next to the chimney gets very hot and may even catch fire. Therefore, internal chimneys should not be installed in walls made of flammable building materials. These systems are also not recommended for powerful boilers.

External chimney is installed in industrial plants with large heating systems. It is customary to install them on an area of ​​a heated room over 600 sq. meters. Such a chimney is also installed if the installation of an internal chimney is fraught with a number of difficulties. For example, in a room with concrete floors and walls, it will be easier to punch a slab than to gouge a channel in the wall.

Installation of stainless steel and cast iron chimneys

Do-it-yourself installation of a chimney through the roof and wall in a wooden house? Step by step instructions + Video Simple and cheap way chimney devices are the installation of a metal pipe.

Installation can be divided into several stages:

  1. Preparing the duct for the chimney;
  2. Installing the chimney;
  3. Installation insulation around the pipe.

The channel for a metal pipe must be made several times larger than its diameter. To leave room for the insulating material.

The metal chimney can be divided into several main parts: condenser, metal pipe, head and adapters for installing tunnels.

To increase the thrust, a gate is installed in the system.

Chimney installation

Before installing the chimney, all pipes must be adjusted to the length . The resulting structure must be placed in a prepared channel. Next, connect a capacitor and a stove to the system. The finish is considered to be the installation of the head.

For rigid fixation of the pipe, it is fixed to the wall every one and a half meters.

Do-it-yourself installation of a chimney through the roof and wall in a wooden house? Step by step instructions + Video When installing steel or cast iron pipes, it is necessary to provide for good thermal insulation of the chimney pipe.This will prevent the adjacent floors from igniting due to a leaky chimney. For high-quality insulation of a metal pipe, refractory clay is used. With the help of clay, they also decorate the joints of the pipe and chimney.

When using a metal pipe, you need to fix it to the ceiling every half a meter. In addition, the bore holes must be made wider, about two pipe diameters.

Installation of cast iron chimney pipes is justified, since such pipes will last much longer. But their installation is associated with certain difficulties. For example, you can cut a cast-iron pipe only with a grinder.

DIY sandwich chimney installation

Do-it-yourself installation of a chimney through the roof and wall in a wooden house? Step by step instructions + Video Combined chimneys made of several materials, perfectly replace conventional metal pipes. Multilayer structures make it possible to reliably isolate floors from overheating by furnace combustion products When installing this chimney, additional insulation is not needed, as a result of which the bore holes are made equal to the pipe diameter.

When installing metal pipes, they are mounted like nesting dolls, and no additional fasteners are required to fix the pipe bends. The pipe bends in these chimneys are connected to each other using construction glue.

The chimney pipes are very sensitive to condensation and therefore should not be used for outdoor chimney installations.

With the correct installation of the sandwich chimney, the pipe will last up to 60 years.

Self-installation of the external chimney

The optimal material for the external chimney pipe is stainless steel . It is lightweight and lends itself well to processing with simple tools.

For the installation of an external flue from a stainless pipe, the following is necessary: ​​ Do-it-yourself installation of a chimney through the roof and wall in a wooden house? Step by step instructions + Video

  • Punch a hole in the pipe adjacent to the boiler. It should be located half a meter from the top of the heating system;
  • Place fasteners on the outer wall at a distance of one meter from each other;
  • Connect the inlet part of the chimney to the boiler;
  • Take out bent pipe elbow from the room;
  • Install the condenser;
  • Fix the pipe to the wall;
  • Install the chimney head and its protection.

This completes the installation of the external chimney. We hope that our article will help you understand the installation and selection of a chimney.
