The second method of calculation
Masonry of the improved (with the stove in the pole) Russian stove: a. general view of the stove; b. 1st row, c. 2nd row; d. 7th row; 1, 3. pans; 2-1.The row of root chimney; 4-slot stove; 5-supports.
The calculation of building materials for masonry can also be done in another way. This is done in the event that there is no calculation, and it is necessary to make it yourself. If you have a poryadovka, it is not difficult to do.
It should be noted that this method of calculation is also relative. The amount of building material, which is in the first row, must be multiplied by the number of rows, and the result obtained must be multiplied by the fill factor. If we are talking about standard heating stoves, then such a coefficient is 0.8, and for stoves with a heating panel such a figure is 0.65. In all calculations it is necessary to take into account the fact that at least 10-15% of bricks need to be discarded.
Building the Vortex Masonry Stove
Then you need to measure the height of the chimney and then calculate the amount of material depending on the section of the chimney:
- for the “foursome” you will need 56 pcs. per linear meter;
- For the “five” it is necessary to use 70 units;
- For a “six-piece” you will need 64 bricks.
First you need to calculate the number, if the heating structure has dimensions of 90 by 90 cm, then it is 3.5 by 35 bricks. Now you need to count the number of bricks in the first row, then multiply by 30 rows in the furnace, and then by the coefficient of 0.65. It turns out the following: 24.5 multiplied by 30, and then the result is multiplied by 0.65, the total comes out to 477.75.
We take 480 pcs., At the pipe height of 4 m we have a “foursquare” pipe:
4 times 56 and we have 224. For cutting and bucking we need another 56. Now you can do the math: 48022456 = 760. Do not forget about the fact that there is a marriage, taking this into account you will need 836. We need to remember about lining with refractory material, for one rib it will take another 25.
As for the clay, it will be used about 30 kg for each hundred. It turns out: 30 multiplied by 8.36, in the end, comes out 250.8 pcs., that is 250 kg of clay.
What kind of stoves are there
Scheme of a Dutch heating furnace.
The classical model of the Holland boiler is purely heating. The rectangular model has a wall of one brick. Later appeared stoves in the form of a triangle, trapezoid, round shape.
They can be heating, with a fireplace, with a stove, a tank for heating water. It is not difficult to create them with your own hands. You need to choose the right option and get to work.
A small stove for villas will take up very little space. Its perimeter. about 50 cm. In this case, it is able to heat several not very large rooms. It is possible to put it made of ceramic bricks. To make the firebox use fireclay refractory type.
Dutch oven with a stove. a fairly rare option, it is often used not only for heating, but also for cooking. It is easy to put it together with your own hands, using full-body ceramic bricks. For the firebox area. fireclay bricks.
Three-turn furnace is laid using red ceramic bricks. For the firebox area will be suitable fireclay.
Round stove was quite often used for heating buildings in hospitals, orphanages, that is, where there was no money for a full-fledged stove. Usually it was laid in one brick, and the top was closed with a steel casing. This furnace-hollandka seems simple, but it is quite complicated in execution, so it is better to entrust its manufacture to an experienced craftsman. You can hardly build it with your own hands.
Scheme of the Dutch oven with a stove.
For a house in which people live all the time, it is necessary that the stove can keep heat for a long time.
It largely depends on its mass and, as a result, the amount of material spent on construction. The coefficient of efficiency is important, on which its efficiency depends.
For a cottage, where the owners are only visiting, the stove must heat up quickly. This is a lighter, economical option, for which little material will go. The ideal option in this case would be Dutch.
Stoves-hollandsky. Scheme, how it works, how much it costs
The principle of this heating system is based on a long winding chimney that allows you to heat several stories with a single design.
The Dutchman consists of a firebox and a long, winding chimney. Also the design includes an ash-pit and several doors. A total of several elements are used in a Dutchman:
- An ash-pan and an ash door;
- The firebox and firebox door;
- Soot chamber and cleaning door;
Each element fulfills its own role and allows the circular construction to reach the maximum power level by distributing a small amount of smoke evenly throughout the heating system.
The structure of the Dutch oven also provides for observance of certain rules in order to maintain fire safety and ensure comfortable use.
The second calculation method
Masonry of the improved (with the stove in the pole) Russian stove: a. the general view of the stove; b. 1st row, c. 2nd row; d. 7th row; 1, 3. s; 2-1.The first row of the root of the chimney; 4. the ashlar of the stove; 5. the supports.
The calculation of building materials for masonry can also be done in other ways. This is done in the case when there is no calculation, and it is necessary to make it yourself. If you have a rowing chart, then it is not difficult to do this.
It should be noted that this method of calculation is also relative. The amount of building material that is in the first row must be multiplied by the number of rows, and the result must be multiplied by the fill factor. If we are talking about standard heating furnaces, then this coefficient is 0.8, and for stoves with a heating panel, this figure is 0.65. In all calculations, it is necessary to take into account the fact that at least 10-15% of the bricks should be discarded.
Then it is necessary to measure the height of the chimney and then calculate the amount of material depending on the section of the chimney:
- for the “fourscore” pipe 56 pcs will be needed. per linear meter
- for the “five” you need to use 70 units;
- For a “pole,” you will need 64 bricks.
To begin with, you need to calculate the quantity, if the heating structure has dimensions of 90 by 90 cm, then it is 3.5 by 35 bricks. Now you need to count the number of bricks in the first row, then multiply by 30 rows in the oven, and then by the factor 0.65. The result is as follows: 24.5 multiplied by 30, and then the result is multiplied by 0.65, the total is 477.75.
We take 480 pcs., at the height of the pipe 4 m the pipe in the “quadruple” is obtained:
4 times 56 is 224. For the partitioning and the partitioning we will need another 56. Now we can calculate everything: 48022456 = 760. Do not forget about the fact that there is a marriage, taking this into account you will need 836. You also need to remember about the refractory lining, for one rib it takes another 25.
As for the clay, it will be consumed about 30 kg for each hundred. It turns out: 30 multiplied by 8,36, the result is 250,8 pcs., that is 250 kilograms of clay.
Brickwork for the base of a stove
At the end of all the calculations we get exactly twenty rows, and now this figure should be multiplied by twenty-four (which turns out four hundred and eighty). Also, we should not forget that an additional fifty bricks will be needed, which then additionally need to be added to the total section.
During masonry also do not forget that the required number of bricks for the construction of the chimney should be calculated separately. And the novice builder will wonder how many bricks in a meter. In order to build one linear meter of standard pipe you will need fourteen brick rows (in each row approximately six pieces of bricks). This means that there are approximately eighty-four bricks in one meter.
Example. If you decide to build a brick pipe four meters long, then you need to multiply these four meters by eighty-four bricks and after all these calculations will turn out exactly three hundred and thirty-six bricks to build four meters of brick pipe.
Similar formula for calculating the building material is characterized by its simplicity and convenience. But, it is important to remember that such a formula is conditional and it is easy to make a mistake when calculating (so recheck the figures obtained several times).

Determining the quality and quantity of bricks
When buying the material, you need to pay attention to checking its quality. Integrity and strength are most important. A good block withstands a strong blow of the hammer, while producing a high-pitched sonorous sound. One of the fragments should be split. inside it should be of a homogeneous color, and the chip should be even. Bumps and irregularities on the surface are the consequence of the technological process and are not considered a defect.
Calculation of blocks is carried out according to the rows. There is simply no other way to get an accurate result. The furnace is a hollow structure, the need is calculated in pieces, which are then translated into cubic meters. It is in such units that products are released and shipped.
Since different varieties of stones will be used in construction, their quantity should be calculated along these lines:
How many bricks do you need for the furnace. how to calculate correctly
One of the oldest options for heating the house is a brick stove. Despite more than a solid period of existence, such stoves are still of interest to many private homeowners. There is nothing surprising about this. brick stoves do not depend on electricity, gas and regular complex maintenance. In addition, the furnace may well be used as an additional source of heat.
Furnace arrangement has a number of nuances. for all the constructive simplicity of the furnace still need to design, choose high-quality materials and qualitatively carry out each stage of the work. One of the stages of the design is to calculate the number of bricks needed for the work. How many bricks are needed for the stove, and we will talk in this article.
Calculation of the number of bricks
Bricks are characterized by the following dimensions:
There are also other options, but it is usually European standards that are not applied in our country.
For furnace construction, as a rule, single bricks are used, sometimes. one-and-a-half. Double in this case is not suitable. The thing is that it is usually hollow, that is, it has a large number of holes in the structure. This is done in order to reduce its mass.
We need only solid blocks. Hollow bricks are much worse at storing heat and deteriorate faster under the influence of various aggressive factors.
Let’s proceed directly to the calculations. For them, we need only two indicators: the number of bricks, of which the lowest solid row is laid, that is, the base, as well as the number of rows. All this is easy to calculate, knowing the dimensions of the blocks you are going to use.
Calculate the amount of material in the base, multiply it by the number of rows of which the oven will consist of. Only those departments that go up to the chimney are taken into account. From the resulting product, subtract a third, and you will have the required number of bricks.
Calculate the chimney separately. There you take the number of bricks in one row, multiply by the number of rows and subtract nothing.

How to build a brick stove. nuances?
People with experience suggest that it is best to hire a professional stove-setter for this purpose. But if you decide to do the masonry yourself, start with the project. It is important to include all the functions you expect to get from the stove: cooking, baking, keeping warm, sleeping space if needed, etc.д. Provide a detailed row. This will help you not only in the process, but also in calculating the building material before buying.
Remember, the furnace, like the house, needs a separate foundation, and it must not be contiguous with the foundation of the house. After the furnace foundation is well cured, lay the waterproofing and start masonry.
