Furnace heating is experiencing a rebirth. Long-burning stoves are considered the best in the rating of heating equipment. Their fundamental advantages are efficiency, economy, the ability to generate more heat and keep it longer. One of the main advantages of such a furnace is the ability to make it with your own hands. To do this, it is enough to have the initial skills of a locksmith and a welder.
What is the benefit of autonomous heat generators of long burning
Why autonomous stoves are more profitable than central heating? The fact is that powerful industrial heating boilers with 100% efficiency lose up to 30% of heat when passing through main and distribution pipelines. Autonomous heating works without heat loss, and its performance is determined by the efficiency of the boiler used for heating. Homemade stoves can be unsightly in appearance, but have an efficiency of more than 90%. You can heat them with wood, coal and waste.
Efficient and economical wood fired pyrolysis boiler retains heat for a long time
What is pyrolysis and sublimation
High efficiency and illegibility in the fuel is achieved through pyrolysis - the thermochemical decomposition of solids. In this case, easily combustible components are formed. Pyrolysis processes can take place in a divided space, and this design is called pyrolysis. If the process takes place in a slowly smoldering layer, then this is a long-burning smoldering stove. The separation of volatile components is called sublimation.
How does pyrolysis work?
The pyrolysis process goes through four stages:
In order for the efficiency to be high, when designing the equipment, it is necessary to ensure that the reducing gases are retained in the hot zone and that heated fresh air is also provided there. With rapid cooling, the energy spent on recovery will fly out into the pipe. Don't forget that carbon monoxide is poisonous.
Note: one of the main advantages of a slow burning stove is ease of operation. Firewood is loaded into it once or twice a day, and ashes are raked out once or twice a week.
Solid fuel stove potbelly stove
Outside the cities, firewood is the most affordable, so the most popular long-burning stove is wood-burning. They heat it not only with firewood from the ridge, but also with waste wood - shavings, sawdust, fiberboard and chipboard waste, small brushwood, straw, etc. There are many heating systems on wood and wood waste. Consider the most efficient, the efficiency of which is more than 70%.
The simplest potbelly stove can be made by hand
A potbelly stove is an economical stove that appeared in Russia after the revolution, during the time of war communism, when many had to endure hardships. The genius of the potbelly stove is that it instantly warms up, as well as the simplicity of its device, the prototype of which was the Russian stove. The upper door is for laying firewood, the lower one is for regulating combustion by supplying air through the ajar door.
The task of the potbelly stove is to keep the heat in at least one room at minimal cost. When using coal, the grate is removed, and the air from the blower is directed to the furnace. It is important not to stuff it chock-full - the volume of the bookmark should be no more than a quarter of its volume. The afterburner is a long horizontal or slightly inclined part of the chimney. Made of metal, it keeps the heat in the room.
Important! The potbelly stove can work on all types of solid fuels, except for sawdust. It is made in the form of a box from sheet steel or round from a barrel. Chimney diameter - 85 - 150 mm.
Such a potbelly stove will not only warm, but also decorate the interior.
When fired, any potbelly stove is red-hot, so its upper surface can be used as a hob. A screen should be installed on the sides at a distance of 40-60 mm from the oven. It protects the room from infrared rays and maintains the temperature at an optimal level.
On the basis of a potbelly stove, you can make a home-made boiler for long burning on wood. To do this, instead of the screen, a U-shaped metal water heater is installed. The distance between the furnace body and the boiler must be the same as the screen offset.
Heating boilers based on a potbelly stove
To heat a multi-room house, you will need a flow-through water heating circuit with a long-burning solid fuel boiler. Such a system can be set up in two ways. The principle laid down in the potbelly stove is taken as a basis.
The first method or boiler number 1
Features of once-through and heat storage pyrolysis boilers:
- The temperature in the combustion chamber is a parameter necessary to control the process.
- Heat dissipation optimization is directly proportional to the boost intensity.
- The insensitivity of the system to the temperature of the walls of the combustion chamber, so the water heater can be built in a technically convenient way.
- Additional loading is possible at any stage and in any allowable quantity.
Note: The type of fuel affects the rate of pyrolysis and the composition of gases. These factors are taken into account by regulating the back pressure at the outlet by throttling the chimney. Regulators of industrial solid fuel boilers are supplied with marks indicating the recommended type of fuel.
The efficiency of once-through boilers can be over 90%. They require power to operate. When shutting down, to further start the system, it is necessary to rake out the caked mass and make a new bookmark in the furnace.
Solid fuel steam boilers use different types of fuel
The second method or boiler number 2
A pyrolysis boiler with a water heater, which does not require electricity and automation, works on the principle of counteraction of two square-cube laws. This refers to the laying of fuel and the lining of fireclay bricks. The algorithm for the operation of a brick kiln:
Loading firewood or coal into a boiler with a thermal buffer is carried out gradually. Sharp fluctuations in temperature are contraindicated for her. If too sluggish fuel is used, it may stall. If there is too much fuel, there is a risk of an accident. If the first heat is not suppressed, the efficiency will not exceed 76-78%, since the instantaneous heat transfer by the lining to the outside is excluded.
English fireplace
There are legends about the attractiveness of fire, its decorative and aesthetic function is of great importance for a person. Can an ordinary person build a long burning stove in his house in order to enjoy not only the warmth, but also the beauty of the fire? The main thing in such devices is not heat transfer and efficiency, but the ability to contemplate the fire during the day.
A handmade English-style fireplace will decorate your interior
There are such designs, and the British came up with them. The classic English fireplace has a smoke tooth, reminiscent of a threshold in a Russian stove, which forms the circulation of flue gases, which does not let fresh air up, directing it to the bookmark, as happens in a potbelly stove.
Due to the large mouth, the efficiency of the fireplace is small - no more than 50%, even if there are smoke turns in the chimney. Smoldering and heat generation from evening to morning occurs only when using Cornish coal or similar coking coal. It is said that in the old days English lords stoked the fireplaces with the rhizomes of pines growing on the coastal rocks.
An example of another "long" fireplace is an ordinary Dutch woman. The blower closes before kindling, firewood is loaded onto a quarter of the firebox, its door remains wide open. The main part of the heat flies into the pipe, but the decorative effect is provided.
The simplest do-it-yourself oven
Solid fuel boilers for long burning, which were mentioned above, are difficult to do with your own hands according to the scheme. The drawings below will help the home-made master to build the simplest heating device on his own. Equipment power - 35 kW, efficiency - up to 85%, burning time - 12 hours. Coal or fuel pellets are used as fuel. Loading with firewood reduces the efficiency to 75%, the burning time is reduced to 8-10 hours.
A drawing of the design of the furnace will help you make it yourself
Slobozhanka - an effective inexpensive furnace design
Slobozhanka is a product of folk art created in the Slobozhanshchina. In terms of its effectiveness, it is better than the products invented by the Soviet branch research institutes.
Scheme and the possibility of improving the design
Slobozhanka is a full-fledged miracle wood-burning stove with a hob. Air is supplied to the smoldering bookmark from the side along a U-shaped trajectory: down the L-shaped air duct and then through the perforated casing. Access is provided to all layers, which contributes to more active pyrolysis, so Slobozhanka works well on coal and pellets. This is an economical device with an efficiency of more than 80%.
The power of the equipment can be increased by complicating its design: stretching the inner perforated casing to the full circumference. To equip the blower with a throttle, a third narrow casing is made to cover the air intakes from the outside.
Vertical Slobozhanka is made on the basis of a barrel
Slobozhanka with mushroom hat
The traditional Slobozhanka has disadvantages:
- It does not accept greasy and tarry fuels. Household waste, chipboard and fiberboard waste form hard deposits on the edges of the openings of the inner casing and the perforated casing of the air duct.
- Careful refueling of the unsmoldered bookmark is required, since at least a small smoldering area should remain free near the perforation of the casing. If this is not foreseen, after the bookmark burns out, the stove will cool down.
The design with a central conical perforated air duct with a mushroom cap is the development of one of the Soviet mailboxes. Created on the basis of Slobozhanka. The cone was freely installed in the unloading hatch of the firebox and removed for cleaning.
The edges of the cap threw the fuel to the edges, a smoldering ring formed under it, which was necessary for stoking the stove. Additional loading could be carried out in any quantity and at any time. Due to the edges of the hat, the air was directed to the smoldering zone, which ensured the omnivorous nature of the structure.
The disadvantage of the "slobozhanka with a fungus" was that when burning household waste or damp pine, it was necessary to check the soot. The cone could stick tightly. It was difficult to remove it without distorting it in this case.

Household slow-burning stoves are a promising direction in heat engineering. Combining with alternative energy resources and waste-free industrial technologies will help prevent an environmental catastrophe. With the external simplicity of the design, the processes in them are complex and not fully developed. These ovens have great potential. Their development and creation is a fertile niche for the creativity of talented DIYers.

2016-08-10A miracle oven is an opportunity to equip unheated rooms with inexpensive but efficient heating systems. Agree, to provide heat to a garage, change house, summer kitchen or a whole country house, connecting a gas boiler is not a cheap pleasure. Yes, and it is not always possible to do this. Because the simple miracle of the stove is a great opportunity to get warm at minimal cost.
Photo miracle oven
Miracle oven is of three types:
- Potbelly stove;
- Furnace in development;
- Buleryan.
Is a miracle stove more profitable than an electric heating system? In most cases, yes. Electricity is not at all cheap now, because the miracle of a wood-fired oven has a lot of advantages.
If you have already had to create something with your own hands from brick, metal and other building materials, then there should be no problems with building a miracle stove.
The advantage of miracle ovens is that they do not require complex piping systems or separate radiators.
Let us consider in more detail what are the main features of a potbelly stove, buleryan and a mining stove.
Potbelly stoves
Although a potbelly stove is an economical way to get heat indoors, and the process of assembling it takes literally a few hours, due to the obvious shortcomings of a potbelly stove, many refuse such an idea:
- Extremely low efficiency factor;
- Despite the rapid heating, the potbelly stove will cool down just as quickly;
- To provide heat to the room for a long time, you will have to constantly be near it to replenish the firebox with firewood.
An electric stove is much more efficient, you don’t have to look after it. Therefore, electric heaters are used more often, despite the better efficiency of the potbelly stove.
Buleryan
Another variation of the miracle stove is buleryan.
What do you need to know about it for those who want to try to assemble a buleryan stove with their own hands?
- To begin with, we note that such a design is better than the electric variety of heaters in several respects at once;
- But at cost, Buleryan is significantly inferior to another wood-burning stove - a potbelly stove. Much more money will be needed to build it;
- Buleryan is quite realistic to assemble with your own hands. But only on condition that you are well versed in drawings, have the skills of a welder and are familiar with plumbing;
- Buleryan differs from the potbelly stove in that the first miracle stove allows the user to adjust the duration of the burning of firewood or other type of solid fuel used. In some models, buleryan is capable of working up to 12 hours on one tab of firewood;
- Heat comes not only from the miracle of the stove, but also from the hot air that passes through the pipes of the stove;
- Pipes are a distinctive feature of buleryan.
Furnace in production
There is an electric version of heating radiators with mineral oil inside. They are efficient, quite economical and do a good job of heating residential premises.
- There is an alternative - a miracle of the design of stoves that use used oil;
- Their disadvantage compared to mineral oil radiators is that it is not recommended to use the miracle of the furnace for working out indoors;
- The oil used emits unpleasant odors, carcinogenic components, inhalation of which can cause health problems;
- A popular place to use stoves for mining is car garages. Old machine oil is not sent to a landfill, but is poured into the furnace of the stove. So inside the garage you can maintain a pleasant microclimate by repairing the car in autumn and winter;
- The speed of heating the premises with the help of a miracle stove for testing is quite high.
Despite their obvious advantages, mining stoves have serious drawbacks:
- The performance indicators are very low, than the stoves in mining are similar to potbelly stoves.
- You have to constantly monitor the combustion process, add fuel, which takes a lot of time and attention.
- These heating devices are not for residential premises, therefore you should not even think about their use inside the house.
General Benefits
The miracle stoves have flaws that no one can argue with. But despite the disadvantages, their advantages allow such stoves to remain in demand, widely used by people for heating summer cottages, private houses, change houses, garages and other small premises.
The general positive aspects of the miracle of stoves include:
- For the miracle of the stove, various fuels can be used. In addition to firewood, all products and waste from the woodworking industry, waste oil, etc. are suitable for them;
- Independence from main energy sources. The vast majority of heating systems in our homes are based on electricity and gas. The miracle of the stove does not depend on gas mains and electrical networks;
- Elementary service. The designs of miracle stoves are very simple, which allows them to be serviced, repaired and even improved with their own hands;
- Possibility of water heating. By placing a container of water on the surface of the stove, you can quickly heat it up for domestic use. Elementary hand washing after car repair in winter is much more pleasant with warm rather than icy water;
- Efficient space heating. Although stoves can cool down quickly, they warm up the room efficiently and evenly;
- Affordable price. You can assemble the simplest miracle of the stove with your own hands from improvised materials. More complex designs require investment, but they cannot be compared with the purchase and installation of gas, electric or solid fuel stoves;
- Minimum operating costs.
The presence of miracle stoves in homes greatly simplifies the solution of some elementary issues of heating and hot water supply. They cannot be considered full-fledged heating equipment for the home, but they perform their tasks 100%.
If it comes to autonomous heating, then you will probably remember such a device, which is called a buleryan. In other words, such a unit includes a firebox, to which several bent tubes are connected. The design allows you to burn different types of solid fuels, including firewood, with high efficiency.
Is it worth making
Such miracle stoves on industrial wood have an impressive cost, you will have to pay more than $ 200 for one model, but the price increases depending on the size of the furnace. Despite the fact that the device of the furnace is somewhat more complicated compared to a conventional potbelly stove, many craftsmen take up the manufacture
Design features of the miracle furnace
In order for the manufacture of the described stove design to be successful, you must study the scheme of the miracle stove on wood, as well as its device. The unit is an all-metal structure, which includes a firebox and bent metal tubes adjacent to it. There should be a door on the front panel through which you will load fuel. In addition, there is a device for adjusting the power. With it, it will be possible to change the combustion modes. The furnace must have a secondary combustion chamber and a branch pipe, the outlet for which will be used by the chimney. Wood-burning miracle stoves will work more efficiently if you do a good job of insulating the chimney. Experts advise using mineral wool for this, the thickness of which should not be less than 3 millimeters. It will also need a blower, air will flow into the furnace through it, it is necessary for the combustion of fuel. The master can also work on creating an oversized ash pan, however, in the process of slow burning, practically no waste will be generated. The rear wall should be double, it allows you to make the unit even more efficient. Some models are equipped with a double case for this.
Preparation before starting work
Before you start making a wood-burning miracle stove, you must stock up on metal pipes, the outer diameter of which should vary from 50 to 60 millimeters. You will also need sheet metal. Since the furnace will operate at a high combustion temperature, metal sheets should be used, their thickness can vary from 4 to 6 millimeters. You should stock up on a standard set of tools and a welding machine, in addition, you will need a pipe bender.
In the process of making a miracle wood-fired oven, you will need to cut out pipe sections that should be bent. At the next stage, a device is made with which the assembly and smoke removal will be carried out. The master will have to complete the dampers for the outlet and blower. We must not forget about the need to make a door that will close the combustion chamber. A wood-fired miracle oven, the price of which can reach 20,000 rubles, must have a frame that will consist of bent pipes. These elements are welded together, and then a partition is installed inside. You will need to install a sheet of metal in the hollow space between the pipes. The door must have a lock, and the next step is to install it. In order for the structure to stand firmly during operation, it will be necessary to manufacture and then weld metal legs.
Work methodology
When it is made from a pipe, it will be necessary to cut individual elements, of which there should be 8 in the structure. The length of each of them should be 1.2 meters. The pipe bender will help bend these workpieces, giving them a radius equal to 225 millimeters. It will be necessary to arrange these components of the furnace in a checkerboard pattern. To remove smoke and accumulated moisture, T-shaped devices should be made, through which the smoke will rush up into the pipe, as for moisture, it will flow down. To eliminate moisture, a special tap is installed to remove water, it is necessary to open it only for these purposes, and then close it again. This is the only way to prevent traction deterioration.
What should I pay attention to when making an oven
When a home-made wood-fired miracle stove is made, you will need to make a special damper, it is necessary to remove smoke from the device. With this component, you can adjust the intensity of traction. For the blower, which is located on the front door, the master must make a blank damper. In order to ensure its reliable and correct fit, you need to use a spring. The most difficult component of a homemade buleryan is the front door. It should close almost tightly. The better it will adhere to the surface of the furnace, the more efficient the whole structure will work. A wood-fired miracle oven, the reviews of which are the most positive, should be made using the technology described in the article. Only in this way will you be able to get a device that will work efficiently and become durable.
Using a pipe of impressive diameter, two rings should be made, which should fit almost tightly into one another. To do this, cut pieces of 40 millimeters in the amount of 2 pieces from a pipe that has a diameter of 350 millimeters. One of the segments needs to be cut, and then deployed. Then the front side of the structure is made, using a ring of smaller diameter. The second ring should be used when installing the door and should be welded to the sheet metal circle. After that, another ring is welded onto the door, which is somewhat smaller than the diameter of the ring located on the front side of the device. In the gap, which is formed by the rings of the door, you need to lay an asbestos sealing cord, and then a damper.
The nuances of the work
The device of the miracle wood-fired oven was described above, your product must comply with the design, which is generally accepted. The next step will need to return to the bent tubes. In the first two, you need to make holes by welding injection tubes to them. These are metal elements, the diameter of which is 15 millimeters. Whereas the length should be equivalent to 150 millimeters. They are needed to ensure the connection of the firebox with convection elements.
Using pipes, you should weld the frame with the partition. For the last element, 6 mm sheet steel should be used. The gaps between the pipes are closed with strips of metal, and then the back wall is welded, which will form the furnace body. To accurately fit the elements of the partition, strips of metal and walls, cardboard blanks should first be made. For the door, it is recommended to make a special lock, which is an eccentric that strengthens the metal hinge. It is located on the wall of the structure. This device will ensure the tightest possible fit between the oven and the door. A wood-fired miracle oven, the greenhouse version of which is presented in the article, must have a door and hinges, the latter are made and hung at the final stage. This also applies to the legs of the stove, which should be as strong as possible.
Conclusion
Making buleryan can hardly be called a simple process; it will be much easier to make a traditional potbelly stove. However, the high efficiency and ease of use justify the effort and time spent. Initially, however, you will need to prepare drawings of a wood-burning miracle stove, they will allow you to carry out the whole process without errors, which will be the key to the success of the work done.
Not every owner of a country or country house has the opportunity to place a natural gas heating system in their possessions. Such a nuisance may arise due to the high cost of connecting to the highway or the lack of a centralized supply. The solution to this problem can be a miracle wood-fired oven. It can be fired with any solid fuel such as wood or coal.
The Miracle Furnace can be fired with any solid fuel, which is convenient if there is no access to natural gas or electricity.
Device types
The traditional Russian stove does not fit into the design of modern buildings, it takes up too much space, and its heating ability leaves much to be desired. In our time, laying a bulky oven is impractical, because you can build a more compact and efficient device if you find suitable drawings. Assembling a miracle oven with your own hands is not as difficult as it might seem at first glance. Such a device can make the room warm and cozy even on the coldest days. Miracle stoves on wood are of the following types:
- potbelly stoves;
- devices in development;
- buleryany or bullery.
If the owner of the house knows how to work with his hands, then with the help of schematic descriptions and video master classes, he will be able to create the device he likes. This will help him to acquire a heating system without the construction of a pipeline and the installation of radiators.
You can see an example of a wood-burning miracle stove in this video:
Metal potbelly stove
Such installations are usually used in small rooms, for example, in garages, sheds, greenhouses and country houses with a small area. They are great for creating a warm microclimate and are an ordinary barrel with thick metal walls. Before its manufacture, a drawing is developed, according to which the unit is subsequently assembled.
The device of the Buleryan furnace is assumed to be self-assembly
The body must have a volume of at least 100 liters, its internal space is divided into two parts, placing a metal partition 5-10 millimeters thick there. A hole is made in it to be able to clean the device from combustion products. The first compartment plays the role of a combustion chamber, and the second is designed to collect ash.
An iron box is placed in the ash pan, in which all the garbage will accumulate. A hole for the combustion chamber is cut out in the front wall, its size is usually 40 × 40 centimeters. For an ash pan, an armhole is also needed, but less than the first by about 10-15 centimeters. It must be equipped with a valve and a door.
The barrel itself is closed with a lid, through which a chimney pipe is brought into the furnace. All parts of the furnace are connected together using a welding machine. The finished structure is installed on legs or a brick stand so that when hot it does not spoil and set fire to the floor. It is worth noting, that such a device has disadvantages:
- cools down quickly;
- firewood needs to be regularly thrown into it;
- low efficiency.
However, the potbelly stove has a low cost and is very easy to assemble. Usually, craftsmen spend no more than 3 hours on making a design. It is able to warm up small rooms, so often such devices are placed in baths.
Buleryan or buller
A powerful air heater suitable for heating various areas is buleryan (otherwise - buller). The price of such a stove is several times higher than that of a potbelly stove, in addition, not every owner can handle its assembly. The device has a more complex design, and its manufacture requires detailed drawings, as well as the ability to perform locksmith and welding work.
The complex structure of a wood-burning stove requires detailed drawings
A distinctive feature of such stoves is the ability to regulate the duration of burning firewood. One bookmark of fuel can provide an average room with heat for 10-12 hours. In addition, the heat comes not only from the device itself, but also from the pipes. They must be included in the device of such an oven.
It is not necessary to use iron to make a buller. The design can be laid out of brick. A large body will increase the power of the stove, and the chimney is easily made from cement pipes.
However, such a device has a serious disadvantage - uneven heating of the air. The floor temperature is much lower than the ceiling. This disadvantage can be compensated by bringing water heating pipes to the device. In this case, the stove will not only warm up the entire room completely, but also provide the household with hot water.
It is worth noting that during the operation of the buleryan, the room warms up not only due to the heat generated by the body, but also from the hot air coming out of the stove. This process looks like this:
- Firewood is slowly burning down.
- The heated air flow passes into a special chamber.
- There it gives off some of the heat to the walls, and then goes outside.
The advantage of such an installation is its ability to burn gases emitted by fuel during combustion. This significantly increases the efficiency and the amount of heat generated. It is for these purposes that the stove is divided into two compartments: firewood burns in the first, and gas burns in the second. This happens with the help of a special arrangement of nozzles. This feature allows you to save fuel, and also eliminates the formation of ash and soot, which makes cleaning the oven more convenient and faster.
Due to the special design, the amount of fuel is reduced and the heat transfer is increased
It is important to position the chimney close to the floor. To better understand the design and mechanism of operation of Buleryan, it is recommended to watch several videos on this topic. Information is never superfluous, and the master will be able to get more accurate and visual information that will help him create a detailed and correct drawing of his own device.
Stoves in development
It is better not to use such devices for heating residential buildings, since burning oil smells unpleasant and also releases carcinogens into the air that are hazardous to health. Motorists should pay attention to such devices, because they can be placed in garages. They have a rather simple and primitive design, so these stoves are easy to make on your own.
Working out devices warm up the air quickly, but have a number of disadvantages: they require constant monitoring, the systematic addition of firewood and are characterized by low productivity.
DIY assembly
Miracle stoves have gained popularity among many consumers. Sometimes there is a need to be able to quickly and efficiently heat a small room without significant material and time costs. In this case, knowledge about the manufacture of heating appliances on wood with your own hands will come in handy. To do this, you need only available materials, tools, desire and ingenuity.
A simple unit from a can
The most simple design has a potbelly stove. To heat a small workshop or garage, you can build a device from an old can. Of course, such a device cannot boast of durability or strength, but it is quickly assembled and easily mounted. All work consists only in arranging the pipe, connecting parts and building a brick stand or legs. For this you need to prepare:
- iron can;
- chimney;
- wire;
- some tools;
- welding machine.
Work begins with the horizontal placement of the can and markings. First of all, they indicate the place where the blower will be. Usually it is placed under the lid and given the shape of a sickle or a rectangle. After that, they begin to create a stove according to the following algorithm:
A simple potbelly stove is ready. The design can be improved by fixing a reflector on the outer wall of the housing, which will prevent heat from escaping. If you attach handles to the device, it will become portable. The advantages of homemade stoves of this type include:
But along with the advantages, potbelly stoves also have a number of disadvantages. So, if the case has thin walls, then over time they will leak, and the device will fail. In addition, damp and tarry firewood can fill the smoke outlet with a thick layer of soot.
A do-it-yourself potbelly stove is an effective heater for workspaces and garages. Its assembly will not cause trouble even for novice craftsmen, and also does not require material investments.
Rectangular heater
When determining the shape and size of the furnace, each master must proceed from his own preferences and the area of \u200b\u200bthe heated room. A person with the necessary skills can always stop at the drawing of the simplest installation, and then improve it by making the desired changes. A simple and multifunctional oven can be made from the following materials:
- sheet metal;
- steel corners with a thickness of 4-5 millimeters;
- pipes 180 mm;
- iron tubes with a diameter of 25-30 mm.
The rectangular body is made from steel sheets welded together. You will need 5 main parts: the bottom, 2 side walls, up and back. On the front wall, a door for the furnace and a blower is cut out.
A rectangular oven is even easier to make with your own hands than a round one.
First, side sheets are attached to the bottom, the joints should form right angles. Their location can be determined using a square or building level. Then the back wall is welded to the structure.
The internal space of the body is divided into three compartments: an ash pan, a firebox and a smoke circulation. The first two are separated using a grate, on which firewood will be laid in the future. It is done as follows:
- At a height of 10-15 centimeters, corners are welded inside the furnace.
- The grate is made of iron blanks 25-30 millimeters wide, their length should correspond to the width of the stove. Such parts can be made from pipes or strips of thick sheet steel.
- Prepared rods are welded to two metal tubes with a diameter of 12-20 mm. The distance between them should be about 4-5 centimeters.
The finished part is simply placed on the inner corners, it does not need to be welded. The convenience of a removable grate lies in the fact that it will be quite easy to get it for cleaning or replacement.
The side parts of the furnace can not be welded, due to which they become replaceable
Then a reflector is placed in the furnace, which is an iron sheet designed to separate the furnace and smoke circulation. It is also made removable. To do this, two metal rods are welded on top, on which the part is placed so that a channel forms in front of it. It is through it that the smoke will pass. It is worth considering that this place will become very hot, so it must be made of very thick material.
Potbelly stove should be made of very thick material
At this stage, the heating system is almost ready, it's time for the final work. First, a lid with a hole for the chimney is welded to the furnace. Then attach the door, latches and curtains. The latter should be made of a steel tube and a thick rod.
The structure is placed on legs or a stand made of bricks, after which a smoke pipe is mounted. It should go outside through a hole in the wall of the room. This element is placed at an angle of 45 degrees, there should be no horizontal sections. The device is ready, now it can be used for its intended purpose.
Even novice craftsmen can make a miracle oven with their own hands if they can read diagrams and handle a welding machine. It is not necessary to immediately take on the manufacture of complex structures, you can practice by assembling a simple potbelly stove for a garage or workshop.
