How to plan a fireplace in a house under construction?

We build ourselves

To build a cassette fireplace, you will need to purchase a high-quality firebox. Its cost is considerable, while finishing can also cost a pretty penny. However, the homeowner does not need to build a foundation, which is usually a cost disadvantage. You can also save on finishing, if an original solution is not required.

Fantasy is not limited to several types of materials for decoration. The firebox is isolated from the frame, which means that the cladding can be performed using any non-combustible materials. Photos of some current solutions reflect the best decor options.

When installing, do not forget about the installation of fireproof glass on the firebox. This is convenient, while increasing the degree of fire safety. To build a cassette fireplace, it is enough to familiarize yourself with the rules for operating fireboxes and chimneys. If the skill is not enough, then it is better to consult with specialists.

A simple approach to comfort

Home is not only a fortress, but also comfort. The fireplace will add a special note to the overall interior, it disposes a person to rest, creates a calm atmosphere. When developing a design with your own hands, do not forget about the rules for operating the device.

Features of work

The name of the cassette fireplace is associated with its design features; it has a special cassette - a steel firebox, which is covered with glass. The closed-type firebox makes it possible to use the fireplace even in a room with the presence of people, as it is considered fireproof. High functionality and short chimney can also be noted as advantages.

Regardless of the type of fuel selected, very little smoke will be emitted. A cassette-type fireplace is an option that can be considered for equipping with heat at home. Cassettes promote the spread of warm air masses through the ducts and heat the house. By equipping the structure with special valves, the air distribution can be stopped at any time.

Cassette fireplaces with air ducts for a country house can have a vertical or horizontal door. This affects the price and, of course, the appearance. The cheapest modification is with a horizontal door. The vertical door makes the price of the structure higher, but its main advantage is the transformation of the fireplace into an equipment with an open combustion chamber.

The door is made of heat-resistant glass as standard. The more glass was used for the production of the door, the correspondingly higher the cost per element. Its shape may differ and be angular, bilateral, in the form of a prism, semicircle, rectangle. Due to the special cleaning mechanism, the door is always clean.

The cassette model perfectly heats the room. The efficiency is quite high and reaches 90% (when compared with a fireplace with an open combustion chamber, which has a maximum heat transfer of 25%). Heating takes place with the help of air masses warming up inside the fireplace. The heated air spreads through the room using air ducts. Air masses can be controlled by closing the air ducts.

If desired, you can organize a long burning mode. It makes it possible to lay logs and leave them for burning at night. Because of this, the fireplace is considered suitable for heating housing outside the city.

The fireplace cassette is a variant of the fireplace insert. Its design includes a convection cover, so it can be operated without ventilation grilles.

Warm air is circulated by convection through the upper layers of the combustion chamber, so heat penetrates into the room. The cassettes can be fitted with one to six turbines. This plays a role in the intensity of warm air circulation. A thermostat is placed in the fireplace cassette.It analyzes the heating in the combustion chamber.

Cassettes can be different in the material of the combustion chamber. The cheapest of them are made of steel, those that are more expensive are made of steel with fireclay lining. Acceptable price solution - cast iron cassettes.

The functioning of the cassette-type fireplace is not the same. There are options for temporary action, and there are options for continuous incineration. All combustion chambers have an air supply control system. As a result, the thrust becomes better, and the temperature drop of the non-functioning cassette does not occur.

Installation features

Compared with brick, cassette type is lighter and does not require additional reinforcement. It can be mounted even on the ceiling of a high-rise building.

If there are doubts about the strength of the house, you need to pay attention to the mass of the fireplace indicated in the documentation.

Chimney

A fireplace with a cassette has its own subtleties of installation, which must also be taken into account when choosing a device. The chimneys of such devices are always under vigilant control. Extreme temperature with the threat of overheating is the main reason for close attention.

When operating a cassette fireplace, you can use a pipe with a smaller section than usual. It is also allowed to use more bends when installing the chimney, since soot does not settle in a cassette fireplace even with prolonged and intense combustion.

Installation rules:

1. A cassette fireplace is safer than a traditional one, but only if all the rules for its installation are observed.
2. The plane for fixation must be absolutely flat. For wooden floors, the layer of wood must be removed and the concrete base must be raised to the level of the floor.
3. The area around the fireplace must also be laid out with heat-resistant tiles. It is better to free the walls next to the heater from finishing and treat with protective materials.
4. When choosing a place for a stove in the house, you should protect it from contact with electrical wiring.
5. If the house has an operating chimney of a suitable cross-section, it must be cleaned and used for installing pipes in the finished channel, saving on costs.
6. Cuffs and couplings will fix the pipes firmly and firmly.
7. The new chimney must have an exit to the outside, fixed from the outside.
8. For proper installation, you need to make gaps between the firebox, floor and walls. You can clarify the distances in the data sheet of the device.
9. The hood is lined with stone, brick, drywall. From the inside, reflective thermal insulation is attached to the walls and finishing material.
10. Basalt or aluminum foil is used to reflect heat and protect equipment from overheating. Use a conventional hacksaw to cut the plaster to a suitable size. Plasterboard structures are fixed with heat-resistant glue. Holes are made for the fastening elements of the box for mounting the exhaust grilles in the gyrsokarton.

Before the first fireplace insert, the structure must be allowed to dry completely. This usually takes up to two weeks.

Final finishing

The joints of gypsum joints are treated with a lime-type putty. The surface can be coated with acrylic paint. In order for wooden parts to serve for a long time, they are impregnated with wax. This prevents drying out with cracking during oven operation. For a rich color and gloss of the brick, it is covered with a solution of white spirit.

Thus, it is quite possible to assemble a fireplace with your own hands. If there is no leakage, then the cassette is inserted correctly. The fire can be set at the minimum mark in the form of a smoldering flame, or you can make a powerful flame that provides warmth for a long time. Modern fireplaces with a cassette have a high efficiency - up to 85%.

Principle of operation

The combustion of fuel takes place in an enclosed space surrounded by walls of steel or cast iron. From the front side, the cassette fireplace is supplied with heat-resistant glass. It plays a protective role, protecting against the possibility of embers falling out, providing access to the firebox and does not let heat through. The latter property is not a disadvantage, since the entire amount of heat is given off to heat the air, because the cassette fireplace heats the room using convection flows.

The cassette is equipped with channels necessary for the supply of air, which ensures the flow of oxygen, and air, which plays the role of a heat carrier. In addition to natural circulation, pumping is provided by special turbines built into the cassette.

The body consists of a double layer separated by an air circulation duct. During the operation of the fireplace, the inner wall heats up and gives off its heat to the air. Passing through the entire channel, air enters the air ducts. They provide heating to different rooms and are adjustable.

The glass door opens horizontally or vertically. The vertically open door transforms the cassette fireplace into an open hearth.

What is a cassette fireplace

The cassette fireplace is a prefabricated structure of several elements. It most often uses a closed-type firebox. It is usually made of cast iron or steel.

The open part of the furnace hole is hidden behind a layer of glass ceramics. The material can withstand heat up to 800 degrees. The door can be either horizontal or vertical. Models with a vertical glass door are much more expensive, since they are an element of the open-type combustion chamber. Most often, classic rectangular doors are installed. But the form can be absolutely any. There are models with a corner door type. Some cassette fireplaces are equipped with a glass-ceramic door in the form of a prism or a semicircle.

Various devices can be used as a "cassette". You can make the base yourself or use an old oven.

"Cassette" can be made of any finishing material. Applied brick, drywall, natural or artificial stone.

The chimney for a cassette fireplace is a shortened version of the classic stove duct. This is done to conserve energy and conserve heat. The air duct is built only from refractory materials.

Installation of a cassette fireplace

Installation of a cassette fireplace can take place as in a country house, and in the apartment. Before carrying out the installation, it is necessary to prepare the area where the future furnace will be located:

1. The cassette fireplace cannot be installed on wooden surfaces, and such common coatings as laminate and parquet are not suitable as a base. They should be removed in the area where the future fireplace will be located. It is best to use a concrete slab as the base. To level the floor surface, a waterproof membrane is used and a screed is poured. The minimum layer thickness is 15 mm.
2. On the wall adjacent to the fireplace, the finish should be completely dismantled. After that, it is necessary to install a layer of thermal insulation over the entire surface of the wall. It is best to use mineral wool for these purposes, as it does not burn. The thermal insulation is fixed with a metal profile, which is screwed on with screws.
3. The air duct, which will be connected to the chimney of the fireplace, must first be cleaned of blockages.

After all the dismantling work has been carried out, you can proceed directly to the installation of the cassette fireplace. Installation must be carried out in stages. First of all, a pedestal is installed for the future fireplace. After that, the firebox is mounted. Next comes the installation of the "cassette". And the last step is the installation of the chimney.

Installation of a pedestal for a cassette fireplace

At the beginning of the work, a pedestal is installed. Any durable material is suitable for it. If you make a cassette fireplace with your own hands, then brickwork or concrete blocks are used as a material.The height of the plinth should be approximately three rows of bricks.

When installing a pedestal, you need to make a camera in the center of the building.

The camera should be as large as the wall. In the place where the camera touches the wall, a hole is made through which cold air will be drawn from the room. Further movement of air flows will occur between the fireplace and the wall.

Installation of a cassette fireplace insert

Install a cassette fireplace insert strictly according to the instructions indicated in the selected model. The gaps between the wall and the fireplace, as well as between the firebox and the "cassette", are spelled out in the instruction manual.

Before installing the combustion chamber on the fireplace, it is necessary to put a sheet of metal and a few pieces of wood. With their help, the structure of the firebox is leveled. After installation, the bars are carefully removed.

Installing the "cassette"

The installation of the fireplace body must be carried out in such a way that gaps are formed between the firebox and the walls of the fireplace for proper air circulation. The size of the gaps differs depending on the used model of the firebox.

Brick walls are laid close to the wall, but at the required distance from the combustion chamber. Another refractory material can be taken for the construction of walls. A cornice is installed on top of the walls. It should be located above the glass-ceramic door.

If a wooden cornice is used in the work, it is necessary to lay a layer of thermal insulation before installation, since wood is a combustible material.

Installation of a chimney for a cassette fireplace

The installation of the chimney depends on whether a ready-made duct will be used or a new one will be installed. If there is already a chimney in the room, there are several installation methods:

A metal pipe for ventilation is installed in an existing chimney. This method is suitable if the duct is a wide structure. For example, a rectangular brick chimney from an old dismantled stove. The steel pipe is connected to the existing chimney. This method should be chosen if the ventilation opening is rather narrow.

It is necessary to pay increased attention to the tightness of the pipe joints, since at the slightest gap, the draft may be disturbed. You can make a chimney yourself

For this, a metal pipe is used. It is installed on the chimney's smoke hole and is led out through the ceiling to the roof. It is worth noting that the pipe, according to fire regulations, must necessarily be with additional thermal insulation.

The cassette fireplace can be easily installed indoors. This is a great option not only for an interesting piece of furniture, but also for a heater with a high level of efficiency.

How does the construction of a cassette fireplace begin?

If the house already has a major chimney, there is no doubt about where to place the fireplace. At the chimney, all surfaces are being prepared to which the fireplace will adjoin.

Even a cassette fireplace requires a project. It is best to plan the location of the heat source during the construction phase of the house.

And if the construction is going on in a finished space, you need to pay attention to the safety of the structure, drawing up a general scheme for installing the fireplace. After determining the installation location, you need to make a base for the fireplace

To do this, a layer of insulation (or thermal insulation) is laid directly on the floor.

A reinforced concrete screed is made on it under the pedestal of the fireplace. Screed thickness up to 15 mm.The light weight of the future structure allows you not to break the finished floor in order to strengthen the base of the fireplace. For the construction of the pedestal, it is convenient to use aerated concrete blocks. Shape and dimension them with a rasp or hacksaw. Subsequently, this durable material can be plastered or veneered. For laying aerated concrete blocks, you will need a solution or glue. The laying is done in the usual way. But you need to take into account that the portal threshold will need to be issued immediately. Let's say, natural stone. A stone plinth is glued to the pedestal using heat-resistant glue or fixing the material with dowels and screws. When creating the basis for the "filling" of the fireplace, one should not forget about the technical openings for the subsequent maintenance of the fireplace. The ventilation and viewing manholes of the fireplace are closed with decorative grilles after finishing work is completed. After completing the masonry, you need to align the upper wall of the pedestal. To do this, it is plastered with cement mortar, 10-15 mm layer. Be sure to use a layer of asbestos cardboard and iron for thermal insulation. It is placed under the cassette slot. Exactly calculate the place of installation of the fireplace cassette in the finished pedestal: it is necessary to plan a sufficient amount of space for the heating system, calculate it so that the metal hose-chimney can be conveniently connected to a part of this system in the cassette. If the cassette insert is mounted in an existing fireplace, the main thing is to connect it to the chimney hermetically. The mobile fireplace cassette is installed on a ready-made pedestal. It is better to first put it on the bars and then remove them one by one, making sure that the cassette fits securely and clearly into the prepared niche.

Cassette fireplace frame and cladding

We proceed to facing the base and shelves of the hearth. When using aerated concrete blocks, steel corners are needed around the perimeter of the structure, which will be the frame of the structure. They are welded at the outer corner.

1. To decorate the mantelpiece, you can use marble, which is laid on heat-resistant glue. It is required to let the glue dry properly. To prevent the slabs from moving during drying, they are pulled together with the chimney base with clamps.
2. The duralumin or profile frame will easily hold the plasterboard sheathing, which is fixed with self-tapping screws for metal (19-25 mm).
3. In addition to the cladding, you will need to fix the protective glass for the cassette on the frame.
4. After the glass, heat-insulating mats are also attached to the frame, one side of which must be foil.
5. If you want to arrange a place for storing firewood, you need to attach brackets to the frame on which a shelf for storing fuel will be installed. She also gets off with heat-insulating mats.
6. The frame is faced with any decorative material: tiles, tiles, natural or artificial stone. It is imperative to use hot melt glue so that the fireplace will serve you for many years.

We make a decision

Before making your choice and deciding in favor of such fireplaces, you will need to study not only the device of the cassette fireplace, but also its distinctive features, which include not only advantages, but also disadvantages:

• Manufacturers offer ready-made lines, the models presented in which differ not only in their size and method of placement, but also in style (from baroque to minimalism);
• Such ovens cool down quickly enough and are not able to continue heating when inoperative. In order for the heat to remain as long as possible after the end of the firebox, it is recommended to make a portal from a material such as brick;
• Some types of cassettes can be connected to special pumps and tanks that heat water and distribute it through the general heating system of the house.Such fireplaces are also classified as having a water circuit;
• Also, the adjustable mechanism can be not only water, but also air. In this case, heating the structure must be done after a short period of time, for example, every 4-6 hours;
• Due to the need for a chimney, such heating units can be placed exclusively in private houses or on the last floors of multi-apartment high-rise buildings;
• The flue duct in such models is always equipped with a glass damper. Due to this, the efficiency and speed of heating with such methods is significantly increased.

Advantages and disadvantages

Any model of a fireplace in different conditions shows its advantages and disadvantages.

The undoubted advantage will be the versatility of the design, which perfectly complements any interior. A rich assortment of models allows you to decorate the interior in your favorite style - from classic to baroque.

Another option is to use the cassette as a boiler. It is necessary to bring a tank to it, which plays the role of a heat accumulator for batteries. This system is applicable only to certain types of cassettes. An alternative option is air distribution to rooms, however, in this case, the cassette must be heated after 5 hours.

If desired, the cassette can be clad with any materials ─ from wood to artificial stone. According to SNIP standards, a cassette fireplace can be installed even for residents of apartments on the top floors of high-rise buildings.

A short chimney can be considered an advantage, since the combustion products are not released as intensely. The chimney must be installed in any case, in accordance with the industrial safety regulations.

Fireplace cassettes: varieties

The manufacture of cassettes is carried out using various materials. Of all the diversity, three main ones can be distinguished:

• Of steel;
• Cast iron;
• Made of steel fireclay lining.

The pricing policy of these fireplaces grows in accordance with the same sequence. The cheapest fireplace constructions are made of steel, and the most expensive ones are made of steel, and fireclay lining is used inside.

The material used to make the cassette greatly affects the price of the product.

The design of a cassette fireplace can include from 1 to 6 turbines. The number of turbines determines how powerful the work and heating of the house will be. To to heat a small room, up to 3 turbines will be enough. This choice depends on the individual preference of the owner.

Varieties of cassette models

The fireplace cassette can be of a certain variety. The choice of a suitable model is made based on such parameters as power, size and heating footage:

• Cassettes for fireplace stoves can be installed in an open hearth. Such models are characterized by low efficiency and are designed to heat rooms with a small area;
• Heat cassettes for fireplaces are often installed in a closed-type combustion chamber. Such stoves are more efficient, and the cassettes themselves have a higher power and are intended for heating houses with a sufficiently large footage.

The most expensive are multifunctional models ...

Advantages and disadvantages of cassette fireplaces

Cassette fireplaces for home have many advantages, namely:

• a closed type of firebox retains heat much better. A smaller amount of warm air goes into the chimney, thereby the premises are well heated;
• cassette fireplaces differ from other types of stoves in compact size and light weight;
• most stoves need constant monitoring during combustion, but the cassette type of design is the safest and allows you to leave a burning fire unattended without fear, only an electric fireplace is safer in operation;
• the firebox can be placed in any "cassette", which allows you to use the most interesting design solutions for decorating the fireplace;
• thanks to a special control system, you can select the required flame intensity;
• cassette fireplaces are allowed to be installed in apartment buildings.

There are several disadvantages in using a fireplace as a heating device:

• the fireplace heats the room only during its work. As soon as the logs are burned out, the fireplace stops supplying warm air;
• to maintain a comfortable temperature in the room for a long time, the fireplace must be heated every 5 hours.

A cassette fireplace has more pros than cons. It is one of the most successful models for home stove heating.

We carry out installation

At the first stage, it is necessary to take care of the chimney. Installation of the hearth is carried out on almost any floor, and additional reinforcement is not required. If the mass of the fireplace plays an important role, you can find out from the attached documentation.

Assembly and installation instructions:

1. The casing and the main part of the fireplace should have a small gap. To separate the outer box from the pipe itself, the surface must be insulated with refractory materials (mineral or basalt wool is used);
2. The diameter of such a chimney has a smaller pipe cross-section than in standard classical furnace units. The number of rotary, horizontal elements and layouts in this case can also be increased;
3. To install the hearth at the first stage, you will need to make the floor covering even. This is necessary to give the structure stability. If the floor is made of wood, it should be partially reinforced with concrete;
4. The floor and wall surfaces located near the combustion chamber must also have an appropriate finish with heat-resistant materials. As additional protection, it is recommended to cover the floor and walls with a special varnish or refractory impregnation;
5. With the initial presence of a chimney with a suitable cross-sectional diameter, it can be used to connect it. Before use, a complete cleaning of the inside is carried out and the tightness of both the entire structure as a whole and each individual joint and section is checked;
6. Fixation of each element is carried out by means of cuffs and couplings;
7. For fire safety purposes, heating elements should not come into close contact with walls, portal and other elements;
8. The walls are additionally insulated, and the framing is made of plasterboard or any other heat-resistant materials.

Only refractory materials are used for finishing and assembly of structures

Construction finishing

The exterior of the structure can be finished according to the following scheme:

• Each joint and joint must be treated with a putty, which contains lime;
• The simplest and most affordable option will be the use of a simple acrylic composition. Such paint tolerates high temperatures and their sudden changes well;
• Individual parts and decor can be treated with wax, which forms a special protective layer, and the main part of the surfaces is impregnated with white alcohol.

Installation rules

The cassette-type model is absolutely safe, but during its installation it is necessary to adhere to some rules. The plane for the fastener must be flat, without flaws and distortions. The fireplace must not be placed on a wooden floor. If the flooring of the house is made of wood, then it must be removed to the concrete, and the concrete itself must be raised to the floor level.

It is advisable to lay out the area for the fireplace with heat-resistant tiles. Adjoining walls should also be freed from decoration and overlaid with heat-resistant material.

Pay attention to the wiring. It should not pass next to the fireplace. Clean the existing chimney completely before installation.

Pipes are fixed with couplings and collars for better reliability

Clean the existing chimney completely before installation. Pipes are fixed with couplings and collars for better reliability.

Chimney mounting options

The new pipe must go outside and be fixed to the outside surface. If the installation is done correctly, then there will be gaps between the walls, the firebox and the floor covering. A frame is mounted on the side parts of the product, which serves as protection against overheating. After installation, the structure should be stable for two weeks.

A cassette fireplace is a model that can be used not only for decoration, but also for heating the whole house. The design can be of different types, with different variations of the cassette and door. In order for it to serve for a long period, adhere to the installation rules. As a rule, the model is low-budget, so everyone can easily afford it.
