Sectional view of the "Engineer" furnace
The stove Professor Butakov "Engineer" refers 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 crossed pipes. Such a device allows the cold air taken from the bottom to heat up and move upward through the pipes.
This contributes to an increase in the heating capacity of the territory. And the pipes that are in the combustion area additionally protect the walls of the heating unit from burning out. Hot air is passed by special nozzles, which are located in the upper part of the flow chamber.
The seal, which is equipped on the door, allows it to close tightly with the handle. Slag enters the ash pan through the openings of the grate. It is located at the bottom of the unit. The ash pan is released from the slag at any time during the operation of the boiler.
For convenience, a stand is used, which can be removed if it becomes necessary to clean the oven. The chimney can be easily detached from the main structure. The boiler can be installed on the floor without a support.
The device of the wood-fired hot-water boiler TMF-Termofor Engineer CHD, SK, TV
The time-tested design of the long-burning heating furnace TMF-Termofor Engineer ČD, SK, TV consists of bent and straight convection pipes securely fixed inside the firebox. Bent pipes are located on the sides of the chamber and cross at the top in order to use the heat of all incandescent gases moving towards the chimney exit for heating. The boiler drum is made of 3 mm thick structural steel. The outer surface of the boiler is covered with heat-resistant organosilicon enamel.
- The firebox door fits snugly to the furnace body thanks to the sealant. The locking mechanism reliably locks the door in the closed position by turning the handle.
- The convector panel is fixed to the door, which helps to accelerate the heating of the ambient air. On the inside, the door is protected by a reflector screen.
- The grate has the form of grooves, through the slots, ash and residues of combustion products fall into the ash box, with which you can easily clean the boiler without interrupting the combustion process .. Under the firebox there is an ash pan with a pull-out ash box. The ash drawer is scoop-shaped and can be cleaned even while the oven is in operation.
Principle of operation
Main processes:
- Pyrolysis. This function is carried out directly behind the flow door inside the firebox.
- Convection. It takes place inside the pipes installed in the structure, forming hot air. Moving along the pipes, he enters the room.
The principle of operation of the furnace is that the fuel in the combustion chamber smolders and does not burn. This is due to the low oxygen content in the chamber. It allows for a long time from 8 to 12 hours not to fill the second batch of solid fuel. Smoldering fuel gives off the same amount of heat as in conventional combustion. This is the main effect of the "Engineer" boiler.
Model range of Butakov furnaces
There is a whole range of Butakov stoves: "Gymnazist", "Student", "Engineer" stove (one of the most famous), "Associate Professor", "Professor", "Academician". They all differ in size and heating capacity. The smallest and least powerful is the Gymnazist, while the largest and most powerful is the Akademik oven. Everyone will be able to choose the appropriate option.

Advantages and disadvantages
Today the modern "Engineer" boiler has been improved. Specialists have increased the diameter in convection pipes, and the pipe walls have become thinner. This change contributes to an increase in the free area, and heat fluxes improve heat transfer. Therefore, the main advantage of the oven is the economy of the model.
Main advantages:
- Increased efficiency. Each structural element is aimed at fulfilling its functional load. It helps to heat the room and food.
- Eco-friendly. The furnace is designed in such a way that almost all the fuel is burned. Therefore, ash does not emit harmful substances.
- Reliable and fireproof. The structure is equipped with a sealed firebox that protects the room from open fire.
- Affordable and durable. Low price goes well with quality.
- Design. The stove is not bulky, has an aesthetic appearance and fits into any room interior.
Main disadvantages:
- Oxygen can enter the furnace through the ash pan.
- For cleaning, the pipe is disassembled into sections.
- The front of the structure deforms over time.
Professor Butakov's stoves: prices for different models
The models differ in power. For example, “Gymnazist” emits six kilowatts of heat, but the “Student” stove is already nine. That's the difference between them. Stove "Student" costs about four hundred dollars (if you buy "Engineer", it costs a hundred square meters more).
The Docent stove will cost the owner six hundred and fifty dollars. Such a firebox can already well heat a large two-story country house. This powerful stove can heat about five hundred cubic meters of living space.
Installation and installation features
It is undesirable to use the boiler in an urban sleeping area. There is no way to install a full-fledged ventilation pipe. In the warehouse, in the country, it can be installed in the center, against the wall, or imitate a fireplace with brickwork. In this case, the warmth will be felt in two adjacent rooms.
Furnace installation rules:
- Make an asbestos coating in the place where the furnace is installed
- Use a 10mm metal sheet over the asbestos floor.
- Insulate the walls of the room from the stove with asbestos cardboard or plaster.
- Place a metal sheet in front of the oven.
- Insulate the ceiling opening with a thermal insulation layer.
- Place the stove on a metal support or brickwork.
- Connect the pipe structure.
- Lead the pipes through the ceiling opening.
- The chimney height must be at least 50 cm above the roof.
Installation example
Model "Professor"
The second most powerful unit after the “Akademik” model.
A 230-kilogram stove with a capacity 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, etc.similar objects.
One tab (200 liters) of fuel will heat the room for a long time.
If the "Professor" model will work only on coal, then it has two modifications concerning the chimney outlet. In the first case - up, in the second - back.
User's manual
Some consumers complain about the rapid combustion of solid fuels in the furnace. But experts insist that they incorrectly install and operate the unit. The fuel must not only be properly loaded, but also properly set on fire.
Arrange firewood correctly
In order for it to smolder as long as possible, you first need to set fire to a small amount of firewood and obtain coal. Then add solid fuel, after which it will smolder for 8-10 hours and give off a large amount of heat.
Key recommendations:
- Before putting the boiler into operation, you need to test it. This will help determine the best way to work the structure.
- To prevent the ignition of objects from the red-hot body of the furnace, it is installed at a distance of at least 40 cm from them.
- During the operation of the boiler, slag appears on the damper and inside the chimney. To get rid of it, you need to use special cleaning agents "Miracle Log" or "Pipe-umbrella", which enhance the movement of the air mass in the chimney.
- It is not recommended to use fuel from coniferous trees, as it emits an unpleasant smell or smoke, and fuel from deciduous trees (birch, aspen, etc.) fill the room with pleasant and environmentally friendly warm air.
- The chimney must be open. The fuel can be placed horizontally or vertically in the firebox.
Review of the heating furnace Termofor Professor Butakov Student
“Fire is beating in a cramped stove” ... This well-known line has not lost its relevance today. We still need a stove that heats our home. But the oven of our day is by no means a "cramped" refuge for the flame. Effective, hot, powerful, modern design models are an excellent solution for rooms or houses that require heating.
Today on the market of boilers-heaters the most demanded model range of air-heating furnaces Thermofor Professor Butakov... One of the most popular among them is the highly efficient independent model Termofor Professor Butakov "Student".
"Student" has modifications - a wood-fired boiler and a coal-fired boiler. Both of them can work on fuel briquettes for closed-type heaters, peat briquettes and pellets.
Purpose and general description
Solid fuel boiler Professor Butakov "Student" designed for uniform and economical heating of residential, utility and industrial premises with a total volume of up to 150 m3.
Due to its design features - a flat horizontal surface - it has increased functionality and provides a full-fledged cooking opportunity.
For the most convenient installation and assembly, as well as compliance with fire safety standards, the boiler has modifications depending on the design of the chimney outlet. The chimney can be installed vertically in the upper part of the enclosure or on the rear of the enclosure, carrying out horizontal flue exhaust to the rear.
Heating is carried out due to gas generation, which occurs in the furnace as a result of smoldering wood or coal. The smoldering process is the main operating mode of the oven. The normal operating conditions for a solid fuel furnace are an air temperature range of –60 ... + 40 ° C. Hot air is discharged through the openings of the side nozzles located on the sidewalls and the upper plane of the furnace.
The outer surfaces are covered with heat-resistant protective organosilicon enamel KO-868.
The boiler is equipped with a stable base plate with fixing holes for secure fixing to the floor in the heated room.
Design and specifications
The stove "Student" has a modern design and is made of special technical steel up to 3 mm thick.
Inside there are convector pipes that surround the combustion chamber. The upper part of the firebox is equipped with gas guiding screens. The system of convection pipes and gas guiding screens ensures the highest possible heat transfer during fuel combustion and gas removal.
To maintain the combustion (smoldering) process and supply additional air to the furnace, there are nozzles bent from the bottom up towards the air flow.
A sealed cast-iron / metal door of the combustion chamber with a light-transmitting screen (or a blind door) is mounted on hinges. The firebox door has a maximum opening angle of 120 ° C. The door locking mechanism fixes it firmly when closed by turning the handle. Reliable fixation ensures complete combustion, heat transfer, and fire safety. A convector panel is mounted on the door, which accelerates the heating of the air in the heated room.
The grates are made in the form of grooves. The grate is located at the bottom of the furnace and promotes forced combustion and the achievement of a high flame temperature at the time of ignition of the furnace. The sealed ash pan can be equipped with an air damper, which additionally regulates the air supply to the firebox.
Combustion products (ash) move through the grate slots into a pull-out ash drawer. The retractable ash pan system provides cleaning of the fuel chamber without stopping the combustion.
The flue channels of the boiler are equipped with a gate for distributing gas supply and for fire safety purposes.
Terms of use and operation
For the initial lighting of the fire and starting the furnace, it is necessary to half-fill the chamber with fuel, light the fire, observing safety measures. Carry out heating for 1 hour, preferably outdoors.
To ignite the boiler, fuel is loaded into the fuel chamber, depending on the modification of the boiler. To ignite and maintain the combustion process, it is necessary to provide access to the primary air through the covered ash pan and grate to the firebox. Secondary combustion air enters through the jets.
To ensure the intensity of the ignition, the ash pan extends. To ensure an economical mode of combustion and gas generation, the ash pan moves in, the gate is covered. If the oven is equipped with a sealed ash drawer, close it as tightly as possible with a padlock. In this case, air is supplied using an air damper. In other cases, the ash pan does not slide in tightly, with a gap of up to 5 mm.
The gases released as a result of combustion are discharged through a branch pipe aligned with the gate and located on the rear or top wall of the furnace. Since the hot air boiler is designed to operate exclusively in gas generation mode, it must not be operated with the furnace door open and / or open flame.
To add fuel, the combustion chamber door must be opened. Before that, it is imperative to open the gate, slide the ash drawer in. After 5 minutes of this mode, open the door, add fuel. When cleaning from combustion products, it is better to leave some ash on the grate inside the gutters. In this case, ash is a natural thermal insulation that increases the resource of the grate.
Advantages and disadvantages
Being a practical and functional product, the solid fuel air-heating boiler Termofor Professor Butakov "Student" also has a number of disadvantages. These include the need to install the stove above 140 mm from the floor or ceiling level, if they are made of combustible materials. A strong heating of the boiler is also possible before the heating of the heat-transfer surfaces.Ash and slag must be watered with water before being removed from the furnace. In addition, in conditions of negative temperatures, reinforced thermal insulation of chimneys is required.
Nevertheless, the "Student" also has undeniable advantages. Among them are the increased area of heating surfaces, enhanced heat transfer and air cooling of the boiler. And a functional firebox with a combustion and air supply control system provides long-term and uniform heating, which allows you not only to heat up, but even cook food on such a stove.
The free flow and exchange of warm air in the heated room is carried out due to the special geometry of the heat exchange tubes. The durability and reliability of the components is ensured by a replaceable grate and a retractable ash pan. Also, the design of the boiler provides for additional equipment with devices that increase heat transfer and efficiency.
Having decided buy heating stove Termofor Professor Butakov "Student" in conditions of a shortage of such energy carriers as gas and electricity, it is the optimal way out for heating and heating. It is an economical, highly efficient, functional and convenient long-term heating device with increased heat transfer. It can be used in almost any conditions. The "Student" stove is a reliable and warm friend.

When the glass on the door breaks, don't be upset. It can be bought for about 3 thousand rubles and can be easily replaced. Using correctly, it will fill the house with warmth for a long time during the cold period. And crackling firewood will create a unique coziness in the room.
History of creation
The stove runs on wood, pellets and other solid fuels
The first sample of such a furnace was made in 2002 in the north of the country, in the Novosibirsk region. Just two months after that, the necessary certificates were obtained, and by 2004 a patent for an invention was issued. Its developer is E. Yu. Zubkevich, a specialist in the field of heat engineering, who named the stove in honor of his relative, Professor S.Ye. Butakov.
A year later, the inventor entered into an agreement with the Termofor company, which mastered the production and release of products. For a number of reasons, in 2008, cooperation with it was suspended and the owner of the patent remained idle. To date, the production of these furnaces has been established on an industrial scale.
