Compliance with the exact dimensions of the fireplace is the key to its reliability. Despite the variety of appearance, purchased products have standardized sizes. For high-quality combustion and the output of the derivative of the process, the presence of an oxygen inflow is necessary. At the same time, its quantity should ensure that the smoke is removed from the firebox exclusively into the chimney.

Peculiarities

The structural features of a classic fireplace suggest that air is supplied to the firebox through the fireplace window. Experts have calculated that the optimal traction speed for a heater of any size should be less than 0.25 m / s. In practice, it is difficult to measure the thrust speed. Before the fireplace is lighted, its presence can be determined by fluctuations in the flame of a lit paper sheet. The user of the fireplace can only be convinced of the sufficiency of the traction force in practice.

Its presence or absence is also influenced by such external parameters as:

• indoor and outdoor temperatures;
• chimney condition;
• type, volume and dryness of fuel.

The main condition for the operability of the fireplace is the observance of the basic parameters, their ratios in the design of the heating unit. The optimal parameters of the heating structure will allow organizing the high-performance operation of the device. The ideal result can be achieved if the basic requirements are followed.

To avoid violations in the device, the fireplace must comply with the following tasks:

• provide heat;
• remove smoke from the room;
• ensure the correct amount of air in the combustion chamber.

The aforementioned standardization of dimensions does not lead to the same appearance for all devices. Among all the parameters of the device, there are those that really affect its performance.

Certain dimensions must be embodied in projects exactly. These include:

• linear dimensions of the furnace opening;
• chimney dimensions;
• distance from the floor to the first edge of the window;
• the location of the tooth;
• parameters of the pipe width in the area of the tooth.

Other parameters do not affect the operation of the device, but only determine the difference between the devices. The dimensions of the portal are often associated with the dimensions of the furnace. They are associated with specific location parameters.

There is no absolute value: the dimensions of the device are closely related to the volume of the heated room. When implementing your own project, try using the table below. It indicates the conditions for the normal operation of the device. Wizards use similar tables.

Dimensional parameter name	Heated area volumes (sq.m.)
	12 15 20 25 30 40
Chimney opening height, cm;	42 49 56 63 70 77
Furnace depth, cm;	30 32 35 38 40 42
Height of the rear part of the furnace, cm;	36 36 36 36 36 36
Width of the rear part of the furnace, cm;	30 40 45 50 60 70
Distance from the beginning of the chimney to the chimney tooth	57 60 63 66 70 80
Fireplace opening width, cm	50 60 70 80 90 100

The data presented in the table is formed from certain values. Always the starting point of calculation for creating a fireplace is the area of the room. In accordance with this value, the size of the fireplace insert is determined. For this, the area of the room is divided by 50. Next, the dimensions of the furnace are determined by calculating the ratio of width and height. Calculations are expressed as a fractional value of 2/3.

The rate of removal of combustion products is interrelated with the depth of the combustion chamber.

With a deepened furnace, the gas extraction rate increases . This is bad, since the heat in the room with such an outcome cannot be expected. With a shallow furnace, a good pulling force will not be achieved. Combustion products will begin to flow into the room. The depth of the furnace must be related to the height of the windows. Two-thirds of the value of the latter is proportional sizes verified over the years.

To make it clearer, we will give an example of the calculated indicators of a fireplace for a living room with an area of 28 sq. meters. To begin with, 28 must be divided by 50, we get 0, 56. These are the parameters of the combustion window. The area of the combustion hole will be 0.61x0.92 = 0.5612 sq. m., the depth of the fuel chamber is (610x2) / 3 = 406.7 mm. The calculated indicator can be rounded off: you get a fuel chamber with a depth of 40 cm.

In addition to the firebox, a standard fireplace includes a ventilation duct (chimney) . The dimensions of the ventilation duct openings are usually 1/8, 1/15 of the dimensions of the combustion box. This takes into account the length of the chimney. The allowed height is 10 meters. In this case, the structure should not be too low. The most optimal height of the chimney structure is 4-5 m. The device is usually supplemented with knee bends.

To remove carbon monoxide, a special device called a tooth is installed.

The required height of the chimney is reached with a specially laid out foundation. Often, the pedestal is not associated with the foundation of the house. For the fireplace, it also serves as a safety platform. Therefore, it is often made protruding beyond the hearth by a few centimeters.

The fuel chamber is located on a pedestal made of non-combustible materials , the height of which can be from 30 to 40 cm. An increase in the height of the pedestal is allowed by the design features of the chimney. In some cases, a place under the pedestal is organized for storing firewood. Calculations of the position of the firebox, as well as the pedestal itself, include the features of the flooring material.

These parameters are considered during the design phase of the fireplace.

Views

The creation of a fireplace project is aimed at embodying the original decor of the room, adding home comfort and coziness. The modern market offers a wide variety of devices. The fireplace is allowed to be installed even in the smallest room. It can be compactly placed in the corner of the room, or consider the option of a device built into a wall niche. Despite all the variety of options, even decorative models are chosen in relation to the dimensions of the room space.

So that the electric fireplace does not look bulky, its dimensions should not be more than 1/25 of the area. For example, for a room of 20 sq. the parameters of the electrical device are 0.8 m. At the same time, the creation of an electrical model does not require a place for storing logs, as well as pipes for removing combustion products. Similarly, the dimensions of the fireplace insert of a decorative unit or biofireplace are calculated.

When choosing these structures, it is also necessary to calculate the dimensions.

For the firebox of a biofireplace, the calculation of the portal will require the preparation of a special drawing in several projections. In this case, the finished portal must correspond to the selected firebox (firebox). Drawing is allowed using special programs that are installed on a PC. The shape of the thermal openings of such fireplaces can be different: it is no secret that the appearance of the fireplace in the house worries people in the first place.

To calculate the values, it is necessary to add the width of the side decorations to the width of the firebox as well as portal consoles. A firebox, a mantel and other decorative parts are added to the height of the firebox. The calculations take into account the depth of the firebox. Stores often offer options for furnaces with ready-made portals. At home, all that remains is to install the firebox into the finished portal.

In addition to different types of imitations, the market offers many options for classic metal fireplaces.

Popular types of metal fireplaces are:

• suspended;
• built-in;
• with an open firebox;

• on gas or with a wood-burning stove;
• with or without doors.

The parameters of ready-made fireplaces for a particular room are selected in accordance with the instructions of the passport for the device. Power is usually indicated in the passport, the dimensions are determined by the heated volume of the room. The power calculation is related to the area of the house, as well as the height of the ceilings. The minimum power of the installation is calculated as follows: the area of the building is multiplied by the height of the ceiling and divided by 20. In terms of choosing the general appearance of the fireplace device, you can be guided by your own preferences.

It is important to consider the recommendations of proportions, as well as the size of the room.
