: For every owner of a private house, one of the most important is the issue of heating. Nowadays, the heating system can be represented by various equipment that differ both in the type of fuel and in efficiency. The fireplace is considered one of the most underestimated, since most people associate it more with an interior item that creates a special atmosphere of comfort, capable of heating only a small space around itself.
Indeed, the efficiency of a traditional fireplace is rather low. Today it is being replaced by an improved air heating system with a fireplace, which allows not only to quickly heat the fireplace room, but also a whole two-story cottage.
The main components of this type of fireplace are the casing and the duct system installed in all rooms of the house. The insulating jacket not only accumulates thermal energy, but also distributes it in all planes, thus increasing the heating efficiency. The usual physical laws come into play: the air under the influence of heat changes its density and rises, warming the room.
A liner is installed inside the casing, which is responsible for the movement of hot air using one or more fans, injecting new portions of air and displacing already hot masses. Thus, the heated air moves throughout the house, heating it from the basement to the upper floor.
A fireplace with an air type of heating has a number of advantages:
You need to think about installing a fireplace with air heating already at the stage of developing a house project, providing for the foundation of the fireplace and competent wiring of air ducts.
The basic structure is identical to a conventional fireplace and includes:
But for the effective operation of the convection structure, additional elements will be needed:
When choosing the fireplace itself, pay attention to the dimensions of the portal and the firebox, the height of the chimney and the section of the chimney. All these points must be taken into account depending on the number of rooms in the house, floors, location of window openings and type of ventilation.
If you do not have practical experience, it is best to contact a specialist when choosing a fireplace.
Designing and installing a fireplace with an air heating system is not an easy and rather laborious task.
However, based on the recommendations of professionals, the installation can be done by hand.
Before starting the installation, prepare the tools and materials:
Even if you want the fireplace to be the main element in the design, first of all, you need to be guided by practical considerations. It is best to place the fireplace in a corner, this will ensure the optimal length of the air ducts and the best quality air circulation. This will heat the maximum area of all rooms in the house.
It is necessary to dig a pit 60-70 cm deep. More often, crushed stone and sand are used to fill the foundation, you can fill the pit with concrete blocks.
The main thing is to make a reliable support for the fireplace. The height of the foundation is determined according to the level of the floor covering.
Be sure to wait until the solution is completely dry, only after that you can proceed to the following stages of work:
The masonry should be carried out in separate rows according to a special scheme, taking into account the presence of all air channels and nodes. The firebox can be formed directly from bricks, or a ready-made metal furnace made in the form of a cassette can be built into a brick portal. Choose according to your taste and wallet, although some experts insist that a built-in metal firebox has great efficiency.
Try to make as little branching of the chimney line as possible, also avoid narrowing, as all this negatively affects the draft. In the hole in the wall or roof where the chimney will come out, install a metal lead-through pipe with mineral insulation. Secure the upper part of the chimney above the roof with clamps and cover it with a grill with a cap that prevents the chimney from clogging.
The air line itself can be made of brick or metal pipe.
In order for the air masses to remain warm as long as possible, it is important to insulate the line with foil. We connect air ducts from flexible pipes to the convection nozzles, which serve to release warm air, we lay this system under the ceilings of the rooms. We install fans in the rooms to create forced draft.
In addition to the aesthetic cladding, it carries another important function - it protects the entire structure, giving it additional strength. Cladding can be done using various materials, based on taste and interior. Fireplaces decorated with decorative stone, red brick or ceramic tiles look very good.
