Professor Butakov’s furnace “Engineer” - operating principle and main characteristics

All about stove installation Engineer

To facilitate installation, each Termofor oven comes with detailed installation instructions.
The company has thought out a convenient and simple design that facilitates installation work. To begin installing the Engineer furnace with your own hands, you should begin by determining the location. It will not be unimportant to decide which chimney to use when connecting.

To heat adjacent rooms, a heat sink is installed on air heating furnaces for routing air ducts, and a heating system pipeline is connected to water heating models. After installation, the stove will be able to effectively heat the entire building, and not just the room in which it is installed.

Requirements for placement

The efficiency and uniformity of heating largely depend on the correct location of the stove. For normal operation, the Engineer stove needs a large volume of air and no obstacles in the way of convection currents.

An essential condition is compliance with fire safety rules. Some points that must be followed are contained in the instruction manual. In particular, it states:

• The stove is installed on a non-combustible base.

Protection is provided for walls and ceilings (where the chimney passes) when installed in a wooden house. The section of the wall adjacent to the stove is insulated with non-flammable insulation, and then covered with steel sheet or brick.

The surface of the chimney is heated to a temperature of over 200°C, which, according to the rules of PPB, requires the use of a special passage unit filled with mineral insulation when passing through floor slabs and roofing.

The special design and the use of a special base simplifies the installation of the Engineer furnace and makes it possible to do the connection yourself.

Which chimney is better

Solid fuel heating equipment belongs to the class of furnaces with high flue gas temperatures. During combustion, inside the combustion chamber, the heating intensity reaches 450-550°C. Although due to the use of gas generation, the smoke at the outlet cools significantly, the temperature still remains sufficient to lead to burnout and deformation of a conventional steel chimney.

Additional requirements apply to traction characteristics. Insufficient pressure leads to backdraft, air locks and other operational difficulties.

Reviews from owners and practice have shown that the optimal choice for convection and water heating stoves is a sandwich pipe and a ceramic chimney. An additional advantage of the systems is the simple installation of the chimney yourself. Sandwich pipes and ceramics are assembled like a construction kit and do not require special skills for installation.

On the Internet you can find negative reviews about the stoves of Professor Butakov Engineer, but they are rather the exception to the rule. Basically, owners point out the advantages of Termofor products:

• Affordable price.

Long service life.

A simple design that allows for independent installation of the stove in the house.

Thermal efficiency due to the ability to connect to a water heating system and air ducts.

All of the above factors ensure uninterrupted and comfortable operation of the Butakov stoves of the Engineer series and explain the popularity of the models among Russian consumers.

User manual

Some consumers complain about the rapid combustion of solid fuel in the stove. But experts insist that they install and operate the unit incorrectly. The fuel must not only be placed correctly, but also ignited correctly.

Stack firewood correctly

In order for it to smolder as long as possible, you first need to set fire to a small amount of wood and obtain coals. Then add solid fuel, after which it will smolder for 8-10 hours and give off a large amount of heat.

Basic recommendations:

1. Before putting the boiler into operation, it needs to be tested. This will help determine the optimal method for operating the structure.
2. To prevent objects from igniting from the hot stove body, it is installed at a distance of at least 40 cm from them.
3. During boiler operation, slag appears on the damper and inside the chimney. To get rid of it you need to use special cleaning agents “Miracle Log” or “Umbrella Pipe”, which increase the movement of the air mass in the chimney.
4. It is not recommended to use fuel from coniferous trees, as it emits an unpleasant odor or smoke, while fuel from deciduous trees (birch, aspen, etc.) fill the room with pleasant and environmentally friendly warm air.
5. The chimney must be open. Fuel can be placed horizontally or vertically in the firebox.

Design and principle of operation

Professor Butakov’s “Associate Professor” stove has a simple but original design, consisting of:

• all-welded 2-chamber body;
• straight and curved convective pipes built into it;
• gas guide screen;
• jets for dosing the intake of secondary air;
• firebox;
• grate;
• ash pan, where there is a special container for collecting ash;
• metal door of the combustion chamber or combined with heat-resistant glass;
• gate welded to the body;
• chimney.

The operation of the furnace is carried out with the simultaneous flow of pyrolysis and convection processes:

• The pyrolysis process is carried out directly in the combustion chamber in smoldering fuel mode. The gas released when wood burns enters the second chamber, where it mixes with oxygen and burns completely;
• the convection process occurs in special air ducts that pass through the firebox and have ends protruding outward. Cold air enters them from below the structure. Then it passes under the influence of natural draft through the combustion chamber and comes out to the top in a heated state.

The firebox door also has a special design. There is a convection chamber inside it, which also participates in heating the room.

How to distinguish a fake from the original?

The “Engineer” model is one of the most popular types of stoves by Professor Butakov. Manufacturers follow construction technology.

How to distinguish a fake? Original designs have oval-shaped nameplates of different sizes not only above the flow door, but also on the door itself.

In all boiler models, the flow door opens to the right. The “Engineer” model has a forced function - using a heat remover, you can change the direction of heat supply. For example, direct heat to another room or to an upper floor. Experts also recommend paying attention to the quality of the seams, the aesthetic appearance of the structure and the set of documentation.

Characteristics

Considering that the Butakov “Student” furnace has various modifications, their sizes and technical characteristics differ significantly. What these devices have in common is the presence of built-in convective channels used to increase heat transfer. Depending on the type, stoves can work both to heat air and provide water heating.

In this mini-review we will look at stoves from.

Wood burning stove

This device is characterized by maximum thermal efficiency and high efficiency, in comparison with coal analogues. It has the following features:

1. Tightness of the combustion chamber - the door closes securely, eliminating the formation of cracks.
2. Improved control of air supply - the unique design of the gate valve allows you to set gas generation or simply combustion modes.
3. High-quality materials - thick-walled structural steel was used to make the body, cast iron was used for the grates and doors.

In addition, the device is characterized by relatively small dimensions, which are:

• 530*780*370 mm;
• chimney pipe diameter 120 mm;
• weight of the entire oven is 77 kg;
• firebox volume 74 l;
• power reaches 9 kW;
• Efficiency is 85%.

The Student stove has an amazing ability to prevent soot from contaminating work surfaces. Even long-term use will not affect the cleanliness of the glass. The burning duration allows you to make bookmarks no more than once every 6-7 hours. The device is equipped with a replaceable grate, which allows air flows to be evenly distributed in the fuel chamber. This eliminates the formation of soot. The design of the ash box allows it to be cleaned without interrupting the combustion process.

Coal furnace

When designing these heating furnaces, the intensity of the thermal load was taken into account. The device has the following characteristics:

• weight – 77 kg;
• firebox volume – 70 l;
• dimensions – 530*370*780 mm;
• Efficiency – 85%;
• Power – 9 kW.

Burning coal requires more oxygen than wood, but produces significantly more heat. Thanks to the 5 mm wall thickness, metal deformation, which can cause rapid breakdown of the furnace, is eliminated. The tightness and thoughtfulness of the design can significantly reduce coal consumption. A similar stove by Professor Butakov “Student”, operating on coal, is an ideal option for systematic heating.

Hydraulic

Thanks to the unique design of the heat exchanger, the long-burning Student water-heating stove has a fairly high heat output. The usual coils in it were replaced with convective channels, partially recessed into the firebox. Thanks to these features, the liquid is intensely heated and enters the heating system. This large-sized device has the following characteristics:

• weight - 90 kg;
• power - 16 kW;
• firebox – 70 l;
• dimensions – 720*370*770 mm;
• Efficiency – 85%.

In addition, the design provides for the installation of heating elements, which allows you to maintain the temperature of the coolant for a long time.

Modifications

• Student Hydraulics
• Student Hydraulic under heating element
• Student Hydraulic with heating element, 9 kW

Line of water heating boilers "Gidravlik"

Developed on the basis of the popular air-heating boiler, with the difference that now it is not air, but water that is heated in convective pipes.
Comprehensive shielding of the firebox with convection pipes allows maximum use of the thermal radiation of burning fuel and the heat contained in the flue gases to heat water. The line is represented by the “Student” and “Engineer” models. Just like air-heating boilers, they differ in size and power. Used to connect open and closed water heating. Firewood and coal are used as fuel. “Hydraulics” are intended for water heating of residential and non-residential premises with a maximum volume of 400 to 670 cubic meters. There are three modifications for the “Student Gidravlik” model: complete with tubular electric heaters (“complete with heating element”), with the possibility of self-installation of heating elements (“under heating element”) and without heating element.

There are two modifications for the “Engineer Gidravlik” model - “complete with heating element” and “under heating element.” The heating element allows you to maintain the required coolant temperature during breaks in boiler operation.

About furnaces "Professor Butakov Student" Hydraulic

• Two boiler models are commercially produced with a power of 16 kW and 24 kW for heating rooms with a maximum area of ​​150 m2 and 250 m2, respectively, with a ceiling height of 2.7 meters. These are “Hydraulic Student” and “Hydraulic Engineer”. These two models are united by their purpose, operating principle, layout and type of fuel used. And they differ in size, power and volume of the heated room.
• The solid fuel hot water heating boiler Student Gidravlik is designed for heat supply to individual residential buildings and public utility buildings that are equipped with water heating systems with natural or forced circulation and hot water supply with a coolant operating pressure of no more than 0.125 MPa (1.25 kgf/cm2).
• Material: the oven is made of high-quality structural steel 3mm thick. The outer surface of the boiler is covered with heat-resistant silicone enamel type KO-868.
• Developed on the basis of the popular air-heating boiler “Professor Butakov”, with the difference that in convective pipes it is now not air that is heated, but water. Shielding the firebox on all sides with convection pipes makes it possible to make maximum use of the thermal radiation of burning fuel and the heat contained in the flue gases to heat water.
• Wood and coal can be used as fuel. It is possible to heat even multi-storey premises with a complex configuration. Used to connect open and closed water heating. The built-in thermomanometer allows you to monitor the temperature and pressure of the water circuit.
• A cast iron door with a translucent window made of heat-resistant glass makes it possible to visually control the combustion process. The cast iron grate is installed in the lower part of the combustion chamber. Under the firebox there is an ash pit with a pull-out ash drawer.

Distinctive characteristics of the “Professor Butakov” boilers:

• The total area of ​​heating surfaces, one side in contact directly with the gas-flame environment, and the other with the air of the heated room, has been developed at a record level.
• Convective pipes along their entire cross-section and along their entire length, from beginning to end, are located directly in a gas-flame environment.
• The front and rear surfaces fully participate in convective heat exchange. Convective pipes are placed on them. The fire door with the convector casing placed on it is also an effective radiator.
• The flow of the gas-flame flow, thanks to the shape of the firebox and gas guide flaps, is directed along the contour of all convective pipes, from their very beginning to their very end, with maximum use of the so-called tail heat exchange surfaces. On the upper horizontal surface, in direct contact with the gas-flame environment, you can warm up food.
• Under the combustion door there is a capacious retractable ash drawer, with which you can remove it in one movement, without interrupting the combustion process. The inlet openings of the convective pipes are horizontal and located at a height of 120 mm from the floor level, which is favorable for the free circulation of heated air.
• The boiler has a fairly high and wide stable base with holes for additional fastening to the floor. No additional bases or podiums are required to install the boiler

Furnace design

Butakov's heating device is very simple. The unit consists of the following elements:

• ash pan for collecting combustion products;
• air outlet pipe;
• two-chamber firebox: one compartment is provided for connecting to gas, the second is for afterburning fuel;
• grate in the form of a damper;
• smoke channel.

The pipes run along the edge of both sides of the furnace, are arranged in two rows, close and cross in the upper part. Thanks to this design, the floor warms up well when cold air moves through pipes located in the combustion zone. Due to them, the heating area increases and the furnace walls do not burn out. Thanks to special jets with hot air inside, located at the top of the firebox, the secondary gas is burned in full. This once again confirms the efficiency of the device: the fuel burns out entirely, and the heat is retained indoors for a long time.

Device

Sectional view of the “Engineer” stove
Professor Butakov’s “Engineer” stove belongs to powerful steel heating systems. The design of the unit consists of two rows of pipes. They run along the sides of the oven. The upper part of the structure consists of intersecting pipes. This device allows cold air taken from below to heat up and move upward through the pipes.

This helps to increase the heating of the area. And the pipes that are located in the combustion area additionally protect the walls of the heating unit from burning out. Hot air is passed through special jets, which are located in the upper part of the flow chamber.

The seal that is equipped on the door allows it to be closed tightly using the handle. Slag enters the ash pan through the holes of the grate. It is located at the bottom of the unit. The ash pan is cleared of slag at any time the boiler is operating.

For convenience, a stand is used, which can be removed if there is a need to clean the oven. The chimney is easily detached from the main structure. The boiler can be installed on the floor without a stand.

Advantages and disadvantages of the Butakov furnace

Among the disadvantages it is worth noting the following:

• High temperature of the steel casing may cause burns.
• When the unit is turned off, it cools down quickly, and the room temperature also drops quickly.

Now a little about the advantages:

• The ash box is large enough and does not require frequent cleaning.
• Butakov's oven is not large, but roomy.
• The construction is durable, which is facilitated by the materials used (cast iron, steel).
• Durable, unpretentious in use.
• The upper part of the model can be used as a hob.
• The fuel can be anything, from firewood to peat or paper.
• Externally aesthetic.
• Installation is quick.
• Eco-friendly.
• Fireproof.

Butakov’s heating devices are widely used due to the uniqueness of their design. In the manufacture of such equipment, inexpensive and reliable materials are used, so that such a heating installation is designed for a long period of operation. In this case, the user is only required to periodically remove accumulated ash using a special container. It collects all the slags formed during combustion, so maintenance comes down to cleaning a special container.

The heating installation is unpretentious in terms of fuel - you can use wood waste, coal, pellets, and ordinary firewood. The only thing is that you should not use resinous wood, which leads to increased formation of soot - everything else can be burned in this firebox without any problems.

Butakov's universal models provide a convenient combination of heating and cooking system. The outer surface of the heater, which is in direct contact with the firebox, can be used as a cooking surface. Such a panel will be very hot, in particular, the temperature can reach 350 degrees Celsius, so such an installation can easily replace a hob.

Heating and cooking stoves "Gimnasist"

The low price of heating equipment is a very important factor, which largely determines the popularity of such models. The low cost is due to the simplicity of the design and the absence of expensive materials. The cast iron and steel used in the production process are designed for a long period of operation, so in the long term Butakov furnaces become even more attractive.

Furnace installation

Before installation, you should prepare a place for the heating stove. This does not require the installation of an additional foundation.

The stove is installed on the floor, on a flat, insulated surface (metal sheets on asbestos cardboard can serve as such a surface).

The base of the Butakov stove design is equipped with holes for fixing, so it can be fixed to the floor.

Adjacent walls also need to be insulated to a level 25 cm above the top edge of the stove. Plaster on a metal mesh or asbestos cardboard with a metal sheet serves as thermal insulation.

The distance from the wall to the stove must be at least 38 cm.

A metal sheet must be laid in front of the oven door.

The hole for the chimney should be thermally insulated.

The Butakov heating stove is installed in a prepared place made of non-combustible materials (for example, on a brick stand).

The last step in the installation is connecting the chimney to the tee and the stove.

Important! All pipe joints should be treated with heat-resistant sealant. Important! The chimney pipe should protrude 50 cm above the roof ridge

In this case, the part of the chimney located in open space must be insulated with material that can withstand temperatures up to +400 °C

Important! The chimney pipe must protrude 50 cm above the roof ridge. In this case, the part of the chimney located in the open space must be insulated with material that can withstand temperatures up to +400 °C

Be sure to insulate the hole in the roof with special material.

The space around the structure can be equipped with any heat-resistant and non-flammable material.

Characteristics

There are several models of the “Engineer” stove; in this case, we will look at a model of a wood-burning stove from the Termofor company. Its price is approximately 14,250 rubles. (without chimney).

This is what the oven looks like in the photo:

Furnace design and operating principle

The operating principle of Butakov furnaces is based on the convection process. The heat-resistant cast iron grate ensures a long combustion process and protects the remaining parts of the installation from high temperatures. If the grille fails, you can easily replace it with a new one.

The grate ensures a uniform combustion process over the entire area of ​​the combustion device and controls the air supply. In order to increase the air supply, you just need to open a special window (the faster the combustion process occurs, the sooner the room will warm up).

Through the grate, combustion products enter a special compartment, from where they are subsequently removed. Cleaning can be done directly while the stove is operating, because combustion occurs in another compartment. The ash compartment is equipped with a “window” with which you can regulate the air supply.

Important! The oven is not intended for long-term heat loads. Therefore, overheating above 350 °C is not allowed

The design of the above furnaces consists of:

• welded steel body with built-in pipes, thanks to which the convection process is carried out;
• convection pipes;
• grates.

Various combustible materials are used as fuel: firewood, briquettes, branches, etc.

An important feature is the flat top of the body, which can be used for cooking and heating water

Advantages and disadvantages

The positive aspects consumers include:

• beautiful and original design;
• With a lot of weight, but due to their small size, these ovens take up little space;
• quick heating of the air in the room (as with all metal stoves);
• through the existing air ducts, hot air coming from the side convection pipes can heat adjacent rooms;
• high efficiency, including due to the fact that, due to the design features, all surfaces of the stove participate in heating the room;
• the ability to regulate fuel consumption;
• low price (unlike, for example, the cost of heating equipment running on gas).

Among the main disadvantages are:

• rapid burning of firewood and, accordingly, fairly rapid cooling of the stove and premises;
• despite the presence of a chimney, the stove sometimes smokes, the doors (especially visible on the glass) and the chimney are covered with soot;
• The oven gets very hot, so there is a possibility of getting burns when touching it and damaging the floor and walls.

Oven with water circuit

It is not necessary to assemble the stove yourself; you can purchase a ready-made version 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.

Flaws:

• Low efficiency. Therefore, a device with a water circuit is recommended to be used as an additional heating equipment.
• No automation. The stove must be lit manually.

Features of installation and assembly

Considering that the surface of the device gets very hot, the installation provides enhanced thermal protection for floors and walls. This can be done in the following sequence:

1. A basalt slab is laid on a wooden or other combustible floor, the surface of which should be sheathed with metal.
2. Walls located close to the device are protected with basalt insulation. This will reduce the distance between the wall and the stove to 50 cm.
3. The presence of supply and exhaust ventilation, both forced and natural, is unacceptable when installing a stove.
4. When laying a chimney, you will need to protect the walls from heat. To do this, install a special fireproof cutting and spark arrester.

If you plan to heat adjacent rooms with heated air, you will need to connect thermal extractors and additional air ducts. The oven is installed in such a way as to facilitate the installation of the corrugated pipe.

What is unique about the Butakov oven?

Let us consider the design features of the Butakov furnace, which improve the technology of this design:

• The fuel tank of the Butakov stove has the form of a truncated parallelepiped, which allows maximum exploitation of the thermal diagram of the thermal decomposition of the fuel.
• The air duct pipes are in a vertical position, located along the entire perimeter of the firebox. The intersection of the pipes is at the top at an angle that was calculated by the professor, so they are located in a gas-flame environment.
• Air flows freely into the gas generator thanks to the cut-off inlet openings at the convective pipes at a distance of 120 mm.
• Special gas guide shields made it possible to use the gas-flame flow as efficiently as possible with the inclusion of inclined tail surfaces. The combustion chamber door is involved in the heat exchange process, thanks to the use of a converter casing.
• Due to the fact that the design is equipped with an ash pan, it is possible to clean spent fuel without stopping the operation of the furnace.
• The upper part of the boiler has a flat surface, heated by a flame, so it can be used for heating and even cooking.
• Installing a replaceable grate made it possible to achieve uniform combustion of fuel, and also made it possible to change combustion processes and increase the temperature.
• When burning fuel, conventional gas heaters leave condensation on the walls of the chimney, which manifests itself in the form of liquid discharge and an unpleasant odor. In the Butakov stove, this problem is solved, since it uses a vertical pipe connecting to the chimney. With the help of such a system, condensate flows back into the firebox and burns out along with the fuel.
• The operation of the Butakov furnace after a full load reaches eight to twelve hours of continuous operation.
• This heating system is absolutely safe and is supported by a stable base, as well as holes for its fixation.

Reviews of Professor Butakov's stoves

You can read many reviews about Butakov stoves on the Internet. The vast majority of them are flattering.

“...The design of Butakov stoves is incredibly beautiful. For example, the Buleryan stove resembles some kind of monster, and you can’t put anything on it. But Butakov is attractive in appearance, and you can heat food on it, and even connect heating to it...”

“...Butakov’s stove is good. Completely satisfied. I have a small house at my dacha (5.5 x 6.2) with one brick, plus ursa and siding. As soon as you turn on the stove in 30-degree frost, after 30 minutes the temperature in the house reaches +27. If you fully heat the stove closer to night, the red firebrands will still be there in the morning...”

“...I bought Butakov as a brick. As soon as I start heating, the heat is released into the rooms through the air grilles. Then the brick heats up, giving off heat even when the fire is completed. I have a two-story house. On the ground floor there are two rooms, plus a porch. I like the products I purchased...”

This article will tell you how to correctly calculate the power of an electric boiler.

Do you have a private two-story house and can’t decide on a heating system? The article at: will help you make the right decision.

Furnace installation

The unit can be placed in the center of the room or built into the wall, simulating a fireplace. In this case, two adjacent rooms will be heated at once.

When installing a stove, the main condition is the unhindered flow of air. The material must be fireproof, and for the base it is better to use a concrete screed

The chimney heats up quickly during operation and startup of the stove, therefore it is important to lay a thermal insulation layer between it and the roof

At the dacha, you can heat it with wood scraps, but the best fuel for such a design is pellets with high efficiency. The operating principle of the stove is as follows: smoldering occurs slowly, so the moisture content of the wood is not particularly important. Dry wood will burn the same way.

The combustion chamber must be extremely sealed. Carbon monoxide does not enter the room, so the stove can be placed next to the sleeping place. One bookmark should be enough for 18-20 hours. The Butakov unit will be the optimal solution when installed in a country cottage with a decent area, or in a country house.

Today, more powerful stoves are produced. For example, a new model “Akademik” with a power of 55 kW has appeared. This is a real record among heating devices of this type. Thanks to the modern design, installation is possible anywhere. A large range of models allows us to satisfy everyone's needs.

If you follow all the recommendations described above, you will be able to make an excellent device with a long-burning system without much expense.

Conclusion

The heating design of Professor Butakov has a long burning time, high-quality construction, high performance and efficiency. Don't get stuck on one type of fuel. The oven is “omnivorous”. It can use different types of solid fuel.

When the glass on the door breaks, don't be upset. It can be purchased for about 3 thousand rubles and is easy to replace. When used correctly, it will fill the house with warmth for a long time during the cold period. And crackling firewood will create a unique comfort in the room.

Principle of operation

Operation

oven is carried out simultaneously by pyrolysis and convection:

1. The pyrolysis process occurs directly in the firebox. In this case, the fuel does not burn, but simply smolders. If you close or open the door vent, you can regulate the flow of fresh air inside. During this process, a large amount of gas is released, which is sent to the second chamber, where, when mixed with oxygen, it is completely burned. At the same time, the air in the room always remains fresh.
2. The convection process occurs in special pipes installed in the structure. Through channels mounted in the firebox with protruding ends at the outlet, hot air is directed directly into the room. Heating is carried out naturally. Cold air is taken in from the lower openings of the pipes. It passes through the entire structure and is sent upward while still hot. However, this leads to sudden changes in temperature in the chimney, which is why condensation is possible, which is a significant disadvantage of this design. But the problem can be solved if you install a pipe. Through it, the condensate will not escape outside, but will settle directly in the firebox, in which it will simply evaporate under the influence of heat.

Potbelly stoves and many pyrolysis units operate in approximately the same way, but there are still some differences. Among them the following are noted:

Pipes in the furnace are not installed arbitrarily, but at an angle

It is important to set the exact angle when arranging the structure yourself. The doors are not just hung on hinges, they contain a convection chamber, which contributes to faster and more uniform heating of the room. The oven, unlike some pyrolysis models, is quite easy to maintain. The ash pan is easy to remove and quick to clean

Among similar designs, it is the Butakov unit that is considered the most efficient, simple, and has high heat transfer.

History of creation

The stove runs on wood, pellets and other solid fuels

The first example of such a stove was made in 2002 in the north of the country, in the Novosibirsk region. Just two months after this, the necessary certificates were received, and by 2004 a patent for the invention was issued. Its developer is a specialist in the field of heating engineering E. Yu. Zubkevich, who named the stove in honor of his relative Professor S.E. Butakova.

A year later, the inventor entered into an agreement with the Termofor company, which mastered the production and production of products. For a number of reasons, cooperation with her was suspended in 2008 and the patent owner remained out of business. To date, the production of these furnaces has been established on an industrial scale.

Advantages and disadvantages

Today, the modern “Engineer” boiler has been improved. Specialists have increased the diameter of convective pipes, and the pipe walls have become thinner. This change contributes to an increase in the open section, and heat flows improve heat transfer. Therefore, the main advantage of the stove is the cost-effectiveness of the model.

Main advantages:

• Increased efficiency. Each structural element is aimed at fulfilling its functional load. It helps heat the room and food.
• Eco-friendly. The firebox is designed in such a way that almost all the fuel burns. Therefore, ash does not emit harmful substances.
• Reliable and fireproof. The design is equipped with a sealed firebox that protects the room from open fire.
• Affordable and durable. The low price goes well with the quality.
• Design. The stove is not bulky, has an aesthetic appearance and fits into any interior.

Main disadvantages:

• Oxygen can enter the furnace through the ash pan.
• For cleaning, the pipe is disassembled into sections.
• The front part of the structure deforms over time.

The lineup

Today there are many models of the Butakov stove on the market. Below we will consider the main ones.

1. The Gymnasist device, with a power of only 7 kW, is capable of heating up to 100 m² of area. The height of the chimney is 5 m.
2. The Student stove (9 kW) can heat a room up to 150 m². The maximum fuel volume is up to 20 kg. The height of the chimney is 5 m.
3. Professor Butakov’s “Engineer” unit (15 kW) will heat a room up to 250 m². The maximum fuel volume is 40 kg. The height of the chimney is 5 m.
4. The Docent stove (25 kW) will heat a home up to 500 m². The design can hold up to 100 kg of flammable substances. The height of the chimney is 6 m.
5. The “Professor” device (40 kW) is capable of heating up to 1000 m² of housing. The maximum fuel volume is 200 kg. The height of the chimney is 8 m.
6. The Akademik unit (55 kW) can warm up a house with an area of ​​up to 1200 m². The stove can hold up to 240 kg of flammable material.

Each model has its own dimensions. The larger the fuel space and firebox, the larger the dimensions of the stove.

The optimal choice of device depends on its purpose and the area of ​​the premises requiring heating.

The compact stove “Gimnasist” can heat up to 100 square meters. meters. Its chimney goes up, so this unit is suitable for country houses and garage buildings. For other models, the chimney exits to the top or is located at the rear of the structure. They are mainly installed in large rooms.
