Professor Butakov's stove: features, models and do-it-yourself making. Products: air-heating boilers "Profesor Butakov" Wood-burning stoves Professor Butakov
Gas generating structures have earned a justified reputation as units that can be categorized as reliable and economical when it comes to the home heating system. There is a device in this category that has recently become very popular. This is Butakov's stove. She received the name by the name of the professor who allegedly invented the principle of her work. What is its popularity and high demand? In order to understand, we present two comparisons.
- This type of furnace consumes 10-12 times less fuel than a conventional metal potbelly stove, with the same heat output.
- The same indicator only when compared with a brick stove - twice.
These two comparisons show how efficient Professor Butakov's furnace is. Why such low fuel consumption? In principle, as in many economical units, the pyrolysis process is used here, which differs in that the fuel burns at a low oxygen content, so the so-called pyrolysis (flue) gas is released. The latter, mixing with oxygen, forms an air-gas mixture, which, when burned, releases great thermal energy.
But that's not all. In addition to the pyrolysis process, convection is used in this heating installation. That is why with the help of this type of stoves, rooms are quickly heated.
Unit device
The device and principle of operation of the heater
So, it is based on two processes.
- The pyrolysis process takes place in the main combustion chamber of the fuel, where it does not burn, but simply smolders. At the same time, it is possible to regulate the supply of fresh air to the combustion zone by closing or opening the vent, through which the air enters the furnace of the device. With such combustion, a large volume of gas is released, which, in turn, is sent to a special chamber, where it burns completely, mixing with oxygen.
- But convection is achieved by installing special pipes in the design. They surround the combustion chamber and bring the ends up, through which the heated air enters the room, heating it. Everything happens naturally, that is, cold air from below is taken in through the lower openings of the pipes, passes through the entire pipe structure and exits.
Attention! There is one minus in this design - this is the formation of condensate due to the temperature drop in the chimney. So this problem is completely solved - a special pipe is installed in it, through which the condensate enters directly into the combustion chamber, where it evaporates.
Boilers Butakov pyrolysis type
It would seem that such a scheme and device are common for many models of pyrolysis heating units. Even potbelly stoves began to be made according to this type. Of course, there is much in common in all the proposed options, but there are also quite serious differences.
For example, pipes installed in the stove are not just a structure that is placed in an arbitrary form. Here it is necessary to accurately take into account the angle of inclination of each pipe. In addition, you will have to adhere to a certain order for installing the pipes themselves around the firebox. Pay attention to the doors, their installation is not just hanging on the hinges, because there is a convection chamber in the doors themselves, due to which the speed of heating the premises increases.
Let's get back to pyrolysis. It would seem that you can think of something else to make this process more efficient. In this design, the inventors succeeded in doing this. All tests of this device confirm that today in terms of pyrolysis this is the most efficient installation. Plus, it was possible to increase the convenience of service. A special ash pan is installed in the stove, which can be pulled out and cleaned during the operation of the unit itself.
All gas generators have one significant drawback - a constant temperature drop. In Butakov's stove, this problem was solved at the expense of the grate.
- First, it's big enough.
- Secondly, it became possible to increase the intensity of fire burning in the furnace due to the grate. That is, if you need to quickly increase the temperature in the room, you just need to install the grate correctly.

Advantages and disadvantages
So, we have already said a lot about the advantages of this type of heating units. These are actually economical and efficient heating stoves. But, unfortunately, not all problems are solved with their help. What can be attributed to the shortcomings?
- Let's start with the fact that if for some reason the oven was turned off, then it cools down quickly.
- When installing the Butakov furnace with your own hands, be sure to place increased demands on the chimney. It must comply with all applicable fire safety rules, be without unnecessary taps and be sure to be insulated.
- During operation of the unit, the outer steel casing is very hot.
And yet I would like to once again remind you of the pros:
- Relatively high efficiency.
- Fast heating of rooms, besides uniform.
- Installing the oven is not a problem, it can be done quickly enough.
- Sufficiently wide power range: from 7 to 55 kW.
By the way, the power characteristics of the stove have become the equivalent of the lineup.
The lineup
Model line
Currently, the manufacturer, and this is the domestic company Termofor, offers several models:
- Gymnasist with a power of 6-7 kW
- Student - 9 kW. Weighs 70 kg.
- Engineer 15 kW, weight 113 kg.
- Associate professor 25 kW, weight - 164 kg.
- Professor 40 kW, weight - 235 kg.
- Academician 55 kW, weight 300 kg.
Specifications
As you can see, the row is actually quite wide. But why such names? The thing is that the author of the heating installation is a professor himself, he taught heat engineering at the institute, so he broke the line in the likeness of the categories of students and teaching staff.
But this is an incomplete classification. There are subsections that differ from each other in the type of fuel used. For example, "Student" and "Engineer" are produced in three modifications.
- Air-fired wood-fired boilers.
- Coal.
- "Hydraulic". These are wood fired water heaters.
What are their differences? Let's start with coal stoves. Since coal has a higher thermal output, the temperature in the furnace becomes higher, which negatively affects some of the metal elements of the unit. So, the convective recoil pipes here are closed with a special casing that protects them from severe overheating. The casing is made of stainless steel, and they are made according to the type of replaceable element. Due to them, the service life of the pipes, and, accordingly, the stove itself, increases.
The strength of the grate has been increased. The boiler door is equipped with heat-resistant glass, so that it is possible to observe the fire visually. Although it should be noted that glass doors have already been installed in the latest production series and in wood-burning installations.
Furnace "Student-Hydraulic"
In hot water models, convection pipes have been replaced with a water jacket. Be sure to install a thermometer with which you can monitor the water parameters. There are some options that increase the functionality of the boiler. For example, heating elements can be installed that will maintain the required temperature of the coolant if the boiler goes out. All hot water options can work on coal, wood, and peat briquettes.
I would like to dwell a little on the Gymnasist model. This is the smallest stove in this category, so it is most often chosen by summer residents who visit their country cottage in the winter from time to time. It should be noted that it can be used to heat a small house with a total area of up to 100 m². but this is the simplest model without modifications:
- She has only one option, in which the chimney only goes up. For other models, the pipe can come out from the top, and from the back, and from the back.
- In its design there is only a steel door. For other models, the doors can be steel, cast iron and cast iron with glass inserts.

Design features
Why we decided to touch on the topic of design features. After all, it has already been mentioned that this is the brainchild of a domestic manufacturer. Everything is so, but the author of the development himself was prompted to invent the famous Canadian stove Bulleryan. So they don't look alike at all? Externally - yes, but the internal design is even very. Of course, we must pay tribute to the Russian engineers, who brought the Canadian to mind, made it more economical and efficient. Therefore, it was necessary to modify some constructive positions.
- Outwardly, it is no longer a barrel.
- Increased heating area.
- Convection pipes are heated along their entire length.
- Butakov furnaces can be used both in normal mode and in gas generation mode. After all, it is not in vain that they belong to the category of long-burning boilers.
- The presence of a grate zone and a box for removing ash.
- It is possible to heat up food on the upper even and flat surface.
- Two types of convection pipes are installed in the design: the side ones are bent towards the top and have a cross direction with each other, straight pipes are located in front and behind. These are a kind of afterburners, through which secondary air enters the second combustion chamber of the flue gas, which supports combustion in it.
And the last question: is it possible to assemble the Butakov oven with your own hands - are the drawings available in the public domain? Everything is possible, but is it worth it? It is better to purchase a factory version - this is reliability, this is safety and a manufacturer's guarantee.
In Russia, stoves developed by Professor Butakov are in great demand. A distinctive feature of the heating device is that it warms up in a short time room with a large area while fuel consumption is minimal. The equipment has good aesthetic characteristics, so it will not spoil the appearance of the room. Such a design you can do it yourself.
Design
The composition of the furnace includes convective pipes, which are installed according to the scheme. Unlike its analogues, the Butakov furnace has a high heat transfer.
The apparatus consists of simple parts:
- ash pan;
- fuel compartment;
- grate;
- chimney;
- pipes for airflow circulation.
In order to use the thermal energy to the maximum, the fuel compartment is made in the form of a parallelepiped. The pipe for this section should only be fixed vertically. On the pipe for air circulation, at a height of 12 centimeters from the steps, you need to make horizontal cuts. This is necessary in order for air to enter the generator.
Also in oven should be a ash pan in which combustion wastes are collected. One bookmark is enough for about 10 hours of heating the room. Also, the duration of the work depends on the specific heating unit models.
Fuel
Compared to other heating analogues, this type of stove has a lot of advantages. First of all, it should be noted that fuel consumption is almost two times less compared to a brick structure. And when compared with consumption is twelve times less. The stove can be heated by any: cardboard, paper, peat, coal.
Types of furnaces
Butakov's devices are produced in several models. It is important to note that all furnace options operate on the same principle, and also have the same design. Models differ in power, dimensions, number of pipes. Therefore, you can easily choose the unit for any room. Existing Models:
- "Gymnasium student". This design is no longer commercially available. because it is ineffective.
- "Student". The stove can heat the room with area 150 m3. It is an excellent choice for living quarters.
- Model "Engineer". The design is capable heat 250 m3.
- "Docent" is designed for a room with area 500 m3.
- “Professor” will heat 1000 m3.
- "Academician".
On some designs, a hob is installed for cooking.

Oven “Student”
This heater is the best option for residential premises, as it has small dimensions, attractive appearance, and is able to heat a room with a large area. The weight of the structure is 70 kilograms, fuel compartment equals 60 liters.
Traditional units have a double furnace door, the outer one acts as a protection. The “Student” design is provided with a special cast iron door with a viewing window made of refractory glass. It should be noted that over time the window will turn black, so you can not install it.
The unit can purchase ready-made with the necessary accessories. Depending on the store, this stove can cost, approximately 20,000 rubles.
Mounting the stove “Student”
The design can be assembled by hand, in several stages:
- First of all, it is recommended to prepare an assembly drawing or download a finished version on the Internet. This will make the job easier.
- Then you should prepare a place for the structure. The surface of the floor and walls must be finished with refractory materials.
- Decide on pipe exit section. Then make a hole in the ceiling, which is covered with non-combustible materials.
- The unit is then installed on prepared stand.
- Mounted with sealant all pipes in series. It is recommended to purchase sandwich pipes that prevent condensation and smoke from entering the room.
- Outside, a special “skirt” must be made on the pipe.
If the Student design is installed on a small distance from wooden parts and surfaces, then the walls must be covered with asbestos-cardboard. From above it is recommended to fix galvanized sheets.
It is necessary to carefully make a hole for the pipe in the ceiling. It should be a few centimeters larger than the diameter of the chimney. The hole made must also be covered with refractory materials, as this area is dangerous. The stove “Student” does not contain a water tank, but if hot water is needed in the house, then you can additionally buy the necessary container. To do this, you need to carefully connect the pipes, container and gate. All joints must be carefully sealed.
After all the accessories of the apparatus “ Student" will be collected, you need to check the stove and light it. It should be noted that the first ignition implies a lot of smoke in the room, as paints and various oils will fade. Therefore, the first start-up of the heater is recommended spend outdoors. If no defects are found, then the “Student” structure can be installed in the room.

Furnace "Engineer"
At the beginning of the century, Professor Butakov developed a new model of a heating device. This unit is in demand among the population. The furnace is capable to heat the room with the area up to 2500 m3. As a fuel, use firewood, cardboard, peat and coal. The oven operates in a temperature range -55 - +40 degrees. Small dimensions allow you to install the structure in any convenient place.
"Engineer" is used for heating of residential premises, garage, greenhouse, industrial warehouses, small stations. It should be noted that this furnace model has a high price - more 30 000 rubles. You can make such an oven with your own hands.
Furnace construction:
- case with two chambers;
- the required number of built-in pipes;
- grate;
- firebox;
- ash pan;
- eyeliner.
It is important to note that the fuel in the apparatus does not burn out, but slowly smolders, which allows saving its consumption and increasing the degree of heat transfer. The internal temperature should not exceed 350 degrees. The first start should take about two hours in burning mode.
Advantages of the "Engineer" apparatus:
- heats a large room;
- one bookmark of fuel is enough for 10 hours;
- convective pipes increase efficiency;
- heats up evenly
- thanks to the ash pan, the drawer can be emptied at any time.
Cons of the unit:
- excess air enters the furnace through the ash pan;
- to clean do-it-yourself pipe, it is necessary to disassemble it into sections;
- front panel over time undergoes deformation.
Furnace installation process:
- Choose a suitable place for installation and cover the floor with asbestos and 10 mm metal sheet.
- If walls are located nearby, then they also need to be isolated with.
- Lay a sheet in front of the machine from metal.
- Isolate the hole in the ceiling.
- The stove is recommended to be installed on a brick stand.
- Connect all pipe sections and lead out.
- The chimney must be on the roof at a height of at least 50 centimeters.
Furnace with water circuit
It is not necessary to assemble the oven with your own hands, you can purchase ready-made option from the developer Butakov.
Advantages:
- Despite the fact that you have to tinker with the water circuit, such a stove is much cheaper than autonomous heating.
- The device can be connected to another heating system.
- Use of various types of solid fuel.
- Excellent aesthetic qualities.
Winter has always been a very difficult time of the year for summer residents or people who live in private homes. First of all, you need to take care of preparing for the heating season, if there is no central heating. A good stove for giving will not let you freeze on cold winter evenings. But the old ordinary stoves for heating the house have long served their purpose. It's time to replace them with new and efficient means of heating, and Professor Butakov's furnaces will help in this.
Who is Professor Butakov?
Professor Butakov successfully taught earlier at the Ural Polytechnic Institute. His works were mainly directed to the field of heat supply and ventilation. He published several works and monographs on these topics. He is famous for the fact that, thanks to his knowledge, the professor was able to create an almost perfect stove for a summer house or a country house, which could heat the room for a long time and efficiently.
What is a Butakov oven?
What is Butakov's oven and why was it called that? All furnaces of Professor Butakov work on the same principle. Because of this, they were all included in the same class of gas-generating furnaces.
Butakov is not the creator of the very principle by which his invention works. This law was known even earlier. So why then was the oven named after him? The professor worked hard and studied the processes that occur during combustion. He examined many other examples of the same ovens and collected all the advantages together. Professor Butakov's stoves have adopted only positive aspects from others, which make them so effective and popular among the common population.
Why are the Butakovites so good?
The most important advantage is, of course, the efficiency of this class. The fuel consumption of gas-generating furnaces is much less than that of conventional ones. In some models, the coefficient of performance (COP) reaches eighty-five percent. For all its efficiency and economy, this furnace also has modest parameters. All these qualities make it very popular.
Where can the Butakov oven be installed?
The possibilities of Professor Butakov's oven are almost limitless. The only thing is that it cannot be installed in an apartment, because it needs a good ventilation pipe. You cannot install a full-fledged ventilation pipe, such as in the country.
Dachas, country houses, industrial premises, warehouses - all this can be heated with "butakovy". You can also use small models to heat a greenhouse (so that the plants bear fruit all year round), a barn or a chicken coop. It can be installed anywhere, it is important that there is a good hood.
What can be loaded into the oven?
A very important indicator is what fuel the stove runs on. If it is adapted for heating with gas, and, for example, it is not available in the village, then what should be done? Here we need solid fuel stoves. Butakov's idea to make an economical solid fuel stove spread to the entire model range. All furnaces of this model range operate exclusively on solid fuel. If heating with coal is planned, then you need to check with the seller, because there are some models that are not adapted to work on coal or peat. For heating, you can use firewood or residues from woodworking. Good for cardboard and other paper products.
Fuel consumption and economy
Fuel consumption is an important indicator that affects the choice of a stove for a country house. Now the fuel for refueling the furnace is not so cheap. And it still needs to be delivered. Gas-fired ovens are very economical in nature, so they are very economical. On one tab of fuel, an average furnace can last about eight hours. This is the main indicator of the efficiency of Butakov's furnaces. At the same time, heat is generated no less than on a conventional potbelly stove or other firebox.
The positive aspects of the Butakov furnace
The most important plus is efficiency and good heating capacity. The small dimensions of this stove are also important, because you also need to find a place for it.
As mentioned above, the average oven can work on one tab for about eight hours, which is a significant plus. The maximum number of burning hours depends on the stove model. The larger the furnace itself, the more the furnace supports the process within itself.
Butakov's furnaces have one useful thing: a system for collecting pyrolysis products. Pyrolysis is the process of burning organic or inorganic substances with a minimum participation of oxygen. After pyrolysis, an unpleasant odor remains, and a lot of soot and soot remains on the pipe and walls of the furnace. The unique collection system of these very products avoids the accumulation of these substances. They are collected in a tube and through it enter the furnace, where they are then burned.
Also, something always remains from solid fuel: ash or very small coals. Previously, especially old bulky stoves, it was very difficult to clear this debris. Professor Butakov's furnaces have a special drawer into which ash, dust or fine coal is poured as it burns. It is now possible to remove the ashes with just one movement, which greatly facilitates the care of the stove.
As for the stove itself, inside it there are many tubes through which air circulates: cold air enters from one end, and warm air exits from the other. Thus, the process of convection takes place. As conceived by the professor, the surface of the furnace is also involved in this process, heating up to sufficiently high temperatures. This is both good and bad. Of course, you can cook on it, but this is inefficient, since it is not designed for cooking, and this process will drag on for a long time. But warm up your borscht or porridge - you are always welcome. Another way to save money is that you don’t need to waste gas from a cylinder (if any), it’s easier to put a frying pan on the Butakov oven and heat it up. But you need to remember about safety precautions. You should be careful near the stove so as not to get burned.
The principle of operation of the Butakov furnace
The principle by which Professor Butakov's furnaces operate was discovered long ago. Fuel, being inside the combustion chamber, does not burn, it smolders. Due to the low oxygen content inside the firebox, wood or coal begins to smolder rather than burn. That is why you can manage for so long on just one tab. By the way, almost the same amount of heat is released during smoldering as during simple combustion, so the efficiency of this system is obvious.
Model range of Butakov furnaces
There is a whole range of Butakov ovens: "Gymnasist", "Student", oven "Engineer" (one of the most famous), "Associate Professor", "Professor", "Academician". All of them differ in size and heating abilities. The smallest and most underpowered is the Gymnasist, but the largest and most powerful is the Akademik stove. Everyone will be able to choose the appropriate option.
Professor Butakov's stoves: prices for different models
Models differ from each other in terms of power. For example, "Gymnasist" emits six kilowatts of heat, but the stove "Student" already nine. Here is the difference between them. The stove "Student" costs about four hundred dollars (if you buy "Engineer", then it costs a hundred more).
The Docent stove will cost the owner six hundred and fifty dollars. Such a firebox can already heat a large two-story country house well. This powerful stove can heat about five hundred cubic meters of living space.
Professor Butakov's stoves are very popular in Russia.
They are able to incredibly quickly heat any room, which indicates the power of the product.
But the furnace operates in a very economical mode.
Suffice it to say that for heating a room, of course, of the same volume, this stove needs half as much fuel as compared to and almost 12 times (!) Less than a “potbelly stove”.
It is curious that it is the "potbelly stove" that is the prototype of Butakov's gas-generating furnaces.
The product runs on solid fuel. As fuel you can use:
- pressed paper
- leftover cardboard
- firewood
- fine coal.
The ideal option for using the Butakov stove is in a country house, to which it is impossible or unprofitable to carry out electric or gas heating.
Butakov's furnaces are practical and quite convenient to use:
- in various warehouses
- for or basements
- various hangars
- construction cabins
- mobile stations
- other technical premises.
The principle of operation of this furnace is as follows: generated through the lower openings, the air flow, warming up in the furnace, enters the room through the upper openings.
The fuel smolders rather than burns because it undergoes a pyrolysis process. The minimum oxygen content leads to thermal decomposition of the fuel.
Butakov's furnaces are long-burning furnaces.
The design of Professor Butakov's heating furnaces is very simple. It consists of:
- Two-chamber firebox (gasification, afterburning);
- Ash pan (for the remains of the used product);
- Grate (this is a damper located between the firebox and the ash pan);
- Air pipes;
- Chimney.
As you can see, nothing new, but the scientist Butakov, taking into account the shortcomings of similar previous designs, managed to eliminate heat loss, increasing the heat transfer of his products up to 85%.
All models of Butakov furnaces have the same purpose, the same principle of operation, identical design and common fuel. They differ in dimensions, power, number of pipes and their diameters and volumes of heated rooms.
The series is represented by six models. The most compact of them, “Gymnasist”, is made to order, the rest are mass-produced. In this article, we will consider three models of this series.
The upper part of the oven is designed for full cooking (warming up) of food. There are modifications with glass.
In addition, the Student oven can be equipped with a cast-iron door or equipped with a steel door.
A 70-kilogram stove has a power of 9 kW, which allows you to heat rooms up to 150 cubic meters. meters. The chimney diameter is 120 mm, and the fuel load limit is 20 liters
Butakov's oven "Engineer"
This 100 kg product is designed for heating large areas.
Power (15 kW) of the Engineer model makes it possible to heat 250 cubic meters. meters.
The chimney diameter is similar to the previous model, but the fuel loading limit is twice as large - 40 liters.
Like the “Student”, the “Engineer” model has two modifications. The first option is equipped with a steel door, and the second is equipped with a cast-iron door equipped with a translucent screen.
Model "Professor"
The second in terms of power, after the “Akademik” model, is the installation.
A 230-kilogram stove with a power of 40 kW is capable of heating a room of 1000 cubic meters. meters.
This model, equipped with a 200 mm chimney diameter, is able to heat large production halls, huge garages and other similar facilities.
One bookmark (200 liters) of fuel will heat the room for a long time.
If the model "Professor" will work only on coal, then it has two modifications regarding the exit of the chimney. In the first case - up, in the second - back.
Reviews on Professor Butakov's stove
“...The design of Butakov's furnaces is incredibly beautiful. For example, the Buleryan stove resembles some kind of monster, and you can’t put anything on it. But Butakov is outwardly handsome, and food can be heated on it, and even heating can be connected to it ... ”
“... Butakov's oven is good. Completely satisfied. I have a small house (5.5x6.2) in one brick in the country, plus ursa and siding. It is worth turning on the stove in 30-degree frost, as in the house, after 30 minutes, the temperature is set to +27. If you completely heat the stove closer to the night, then the red firebrands will lie in the morning ... "
“... I bought Butakov in brick. As soon as I start to heat, heat is given off through the air grilles into the rooms. Then the brick heats up, giving off heat, even at the end of the firebox. I have a two-story house. On the first floor there are two rooms plus a porch. I like the product I purchased…”
Do you have a private two-story house and you can not decide on the heating system? The article at: will help you make the right decision.
So, why is it worth buying Butakov's stoves?
- The design of the firebox of these models resembles a truncated parallelepiped. Therefore, during the thermal decomposition of fuel, thermal energy is used to the maximum;
- Air pipes inside the perimeter of the firebox are located strictly vertically. They intersect only at the top, being in a gas-flame medium, at a specially calculated angle;
- The inlets of the air pipes are provided with horizontal cuts located 120 mm from the base of the footrests. This allows air to enter the gas generator absolutely freely. And the presence of gas-directing shields allows the most efficient use of the gas-flame flow;
- Due to the location of the convector casing on the furnace door, the door is a full-fledged “participant” in the heat exchange process;
- Due to the ash pan (special box for waste products), it is possible to clean the ash without interrupting the operation of the boiler;
- The upper surface of the Butakov furnaces is in contact with the flame flow. And since it is horizontal, it is possible to heat food on it.
- Butakov's gas-generating boiler burns evenly. If it is necessary to increase the temperature and speed up the combustion process, a large replaceable grate is used;
- The professor drew attention to the fact that condensate usually settles on the walls of the chimneys (during the combustion of fuel). These are liquid decomposition products with a very unpleasant odor. Therefore, the scientist decided to use a vertically mounted chimney connection pipe. With this decision, he achieved the return of liquid products back to the furnace, where they burn out completely (without residue);
- The furnace after a full bookmark can operate in the range of 8-12 hours, the operating time depends on the model;
To ensure additional safe operation, when installing Professor Butakov's stove, it can be fixed to the floor.
1 Comment
Each model has its own dimensions. The larger the fuel space and the firebox, the larger the dimensions of the furnace.
The optimal choice of device depends on its purpose, the area of \u200b\u200bthe premises requiring heating.
The compact Gymnasist stove can heat up to 100 sq. meters. Its chimney goes up, so this unit is suitable for summer cottages and garage buildings. For other models, the chimney goes up or is placed behind the structure. They are mainly installed in large rooms.
Where are these units used?
Gas-generating furnaces are widely used where gas is not supplied or is supplied intermittently, and there is no electricity. Garage cooperatives, as well as hangars, building change houses, mobile stations are interested in acquiring such structures.
Self-manufacturing
Before proceeding with the construction of the device with your own hands, you need to study its scheme:
The assembly sequence of this unit is no different from the installation of gas-generating furnaces. The basis of the device is a metal barrel.
To get a quality unit with safe, economical and efficient heating, follow the instructions below:
- Using a grinder, you need to cut off the top of the barrel, smooth out the sharp edges with a hammer and
bend them down.
- In a steel sheet, it is necessary to cut a circle with a diameter of 1.5-2 cm. This is much smaller than the corresponding size of the barrel itself.
- In the cut out element, it is required to make a hole with a diameter of 10 cm and weld a steel pipe of the same size to it.
- To the bottom of the product, you will need to attach channel sections using a welding machine and install them so that they can move freely inside the barrel. During the operation of the unit, metal beams will put pressure on the fuel.
- A damper is mounted on top of the pipe, and the stud is installed strictly vertically.
- This element must be fixed by welding. A hole must be drilled on the edge of the valve, cut from steel with a diameter similar to the corresponding pipe size. After installation, the stud should cover the product.
- The damper is screwed on with a nut. Installing this element allows you to further monitor the volume of incoming air, as well as the intensity of the device.
- The side of the cover must be leveled with a hammer. The edges for a snug fit and fit to the base must be bent outward.
- In the lid, you need to make a hole with a diameter of 10.5 cm. To do this, stock up on a chisel.
- The pipe must be welded to the pancake and brought out through the hole made in the lid, which must be welded in the future.
- For the base of the furnace, you can prepare a not too deep brick platform.
- In the upper part of the device case, it is required to cut a hole with a diameter of 15 cm. A smoke channel will pass through it, which is 1.5 times longer than the case itself. On top of the structure, a previously measured pipe segment is welded to the hole.
- At the bottom of the device you need to make a small square hole, then weld the door to it. This will be an ash pan - a hatch for collecting ash, where the box is installed for convenience and ease of cleaning.
- The lower part of the chimney pipe is carefully welded. It is desirable that the product stands on legs.
- An elbow is welded to the channel, a furnace is connected. The design is fixed with a clamp. A fiberglass base is pre-placed under this device for the tightness of all connections.
If there is no barrel, then a fire extinguisher can be used for the base of the furnace, from which the body must be removed. For these purposes, a gas cylinder is also suitable. The device is assembled in the same way.
Furnace installation
The unit can be placed in the center of the room or built into the wall, simulating a fireplace. At the same time, two adjacent rooms will be heated at once.
When installing the furnace, the main condition is the unhindered flow of air. The material must be refractory, and for the base it is better to use a concrete screed. The chimney heats up quickly during operation and start-up of the furnace, therefore it is important to lay a thermal insulation layer between it and the roof.
In the country, you can heat with wood trimmings, but the best fuel for such a design are pellets with high efficiency. The principle of operation of the stove is as follows: smoldering occurs slowly, so the moisture content of the firewood does not really matter. Dry timber will burn in the same way.
The combustion chamber must be extremely tight. Carbon monoxide does not enter the room, so the stove can be placed next to the bed. One bookmark should be enough for 18-20 hours. The Butakov unit will be the best solution when installed in a country cottage with a decent area, or in a country house.
To date, more powerful furnaces are being produced. For example, there was a new model "Akademik" with a capacity of 55 kW. This is a real record among heaters of this type. Thanks to the modern design, installation is possible anywhere. A large range of models allows you to meet the needs of everyone.
- Carry out a test before using the unit. Try to flood, while choosing the optimal mode of operation.
- The distance of the furnace from flammable objects must be at least 40 cm. The structure heats up quickly, so the hot body can be burned, and nearby objects will melt.
To start the oven, follow these steps:
- remove the top cover;
- get the pancake along with the welded pipe;
- load any fuel material; the main thing is that it be solid;
- the bookmark should not cover the chimney; firewood is recommended to be placed tightly and vertically: this way more fuel will fit, and burnout will be uniform;
- on top of the firewood, you need to lay twigs and paper, which you need to moisten with kerosene for combustion efficiency;
- return the pancake and lid;
- set fire to the paper and put it on top of the firewood;
- wait for the fuel to ignite, after which it is necessary to close the damper of the pipe to supply air to it.
