Solid fuel boilers do not work as common, in which heat goes directly from the fire. Such aggregates are installed in private and summer houses, country cottages or production rooms. At home, you can make a solid fuel boiler with your own hands using special schemes and drawings. It must be adhered to step by step instructionsBy observing all security measures.
Do not forget about security measures with a similar boiler
In the boiler on solid fuel, one bookmark can be enough for seven hours of burning. If you do not raise firewood on time, the temperature in the room will start quickly. This is due to the principle of free gas movement: Hot air flows rise and then go out. The long-burning device can maintain heat in the room one or two days, the most expensive models are withstanding up to seven days.
According to the drawings of a solid fuel boiler, it can be understood that the effectiveness of its work is the right structure. In the usual unit at the bottom there is a fuel, the flame is raised to air distributors. Then hot oxygen enters the heating chamber, which leaves the pipes to heating radiators. The fan provides a timely air supply to the flame.
In this video you will learn how to make a heating boiler with your own hands:
Two combustion chambers are located at a solid fuel boiler, and the furnace itself is located at the top. Firewood or coal is laid in it, and the air comes with special fans. When the top layer is roasted, new oxygen flows are served. This allows wood burning very slowly, giving a greater amount of heat to the room.
You can purchase several models of such equipment. Budget aggregates include wood boilers - They can not be laid anything except for manneys. The remaining devices are drowned with coal, sawdust, household garbage, briquettes.
On engineering drawings solid fuel boilers Picture with your own hands the location of the main elements:
The roller design is completely sealed, it does not perform the functions, as the air goes through the top. Both chambers, ash tank and chimney are located in a steel boiler housing with a thickness of 5-7 mm thick.
The homemade aggregate has large sizes and complex design. It is better to use it for heating a cottage or house with large rooms. The device will not be economical in small duty houses. The advantages of the boiler include:
This boiler has a number of advantages and minuses. Made with their own hands solid fuel boilers also have a number of advantages over the purchase option: the homemade unit will cost cheaper, it can be done more powerful, and also change the design to more convenient. Among the disadvantages are allocated:
Press the steel sheet form the cylinder can be only using a roller machine. But you can replace steel with an empty propane cylinder or durable iron pipe with a suitable diameter. The thickness of the walls of the container should exceed 5 mm.
First you need to prepare all the schemes and drawings. Thereafter materials and tools should be selected.that will be needed when working:
On the cylinder, according to the drawing, they paint all marking, the hole is cut under the ash tank. In the upper part, they put a mark on which the top will remove. It must be cut off with a grinder. In the center you need to make a discourse to exit the smoke tube. A metal ring is welded onto the lid, the steel on the internal and outer sides of the cylinder are attached.
To assemble such a boiler do not forget about required tool To the bottom of the prepared pipe attach a metal circle, which will play the role of the air distributor. From metal cut fasteners, weld them along the cut line, laying asbestos cord. To the cut-off top you need to weld the handle and put on the cover on the balloon. Bulgarian produce the nozzle, fasten it with chimneyConnect the design with the housing.
Kohlnik fasten the metal door. Measure the inner diameter of the cylinder, make marking on the steel sheet. It is necessary to cut the circle with a diameter greater than the housing to 5 mm. From a metal corner, six identical blades are made and attached to a round part - this is the future fan. The number of firewood laid depends on the size of the heat exchanger. It must be welded from the steel walls, then insert the finished element into the housing.
Sheet metal covers the entire boiler body for greater strength and reliability. Top and bottom are made pipes for input and air outlet. In the steel cut out the punishment for the ash, so that it coincides with the hole on the cylinder, the metal is weld on top. This forms a hermetic case with a round firebox inside. In the finished design you need to load fuel. To do this, remove the lid, get the oxygen feed limiter, load coal or firewood. The pipe is returned to the place, throw a burning knob in the furnace. As soon as the fuel starts to light up, you need to close the lid. The limiter will be descended as firewood is combustion.
To install your own boilers on the corner in the room you need to highlight a special place. Additionally, the incision should be made to output the chimney in the roof or wall. Under the balloon you need to make a small pedestal of bricks. The adjacent walls are trimmed with steel or other heat-resistant material. All the junctions of the chimney are wicked by sealant, attach it to the pipe on the boiler, and the second end is derived out.
Before installing a coal boiler in the house, it is necessary to test it outside. Since the tip is cut off from the cylinder, then the operation time of the furnace is cut from ten to five hours. If there is no desire to put firewood every period of time, but you can connect two cylinders together.
The sealant can be replaced with asbestos cord, sinking it on all the joints and seams. It is necessary to constantly monitor the temperature of the system and prevent its overheating. The pipeline does not install a shut -tented valve.
The room must be constantly ventured, because even a small amount of carbon monoxide can lead to poor well-being. Next to the design do not hold light-faced items, protect it from children and domestic animals.
It is advisable to equip your own hands for the TT of the boiler a separate subsidiary, as it is a little contaminated while working. It is necessary to monitor its condition, the amount of fuel and oxygen access.
If you do not want to spend money on expensive gas and other boilers, then you will probably wonder how to make a solid fuel boiler with your own hands. The efficiency of such a boiler is approximately one level with the furnace, and make the boiler with his own hands is not so difficult, as it may seem at first glance.
Drawings of solid fuel boilers can easily find in open sources and focus on them when working. Today we will tell you how to make a boiler on solid fuel with your own hands and that it will be necessary for this.
The designs of solid fuel boilers are different. Some are provided so that with their help you can not only damop the house and warm the water, but also cook food. This will increase the efficiency of the boiler on solid fuel, and reduce the cost of heating the premises.
For work on the manufacture of a solid fuel boiler with their own hands drawings, materials and tools will be required.. Solid fuel boiler consists of the following items:
In addition, an important, but optional element of the system is a thermoaccumulator, which evenly distributes heat throughout the room. This is a metal tank desired sizewhich are installed with your own hands on a solid fuel unit, and accumulates thermal energy with active firebox. When the firebox is temporarily suspended, the carrier circulates on highways, nerve air.
Also above the thermoaccumulator, you can install an additional hot-liquid drive for household needs, in order to ensure better comfort for tenants.
Before starting work on assembling a boiler on solid fuel with your own hands, you need to make the drawings of the boiler and the entire heating system. Such drawings can be found on the Internet and ready, but it is better to adapt them to their housing, since each heating system needs to create your approach.
To make your own hands to collect a hardware fuel boiler, you need to prepare the following:
To purchase construction Materials At a bargain price, it is best to contact the company that is engaged in metal, and can provide a good discount.
Work on the assembly of the boiler provides for welding, so full list of working instruments looks like that:
You need to start work only if you have work skills with welding and other tools that will be required when assembling the boiler.
With the competent organization of the workflow on the assembly, nothing complicated in the work will not be. It is advisable to build a boiler in a specially designated room, for example, in the workshop. Details for boiler make on the workbench.
A key element of any boiler heating, regardless of what fuel it will work, is a firebox. To make a firebox with your own hands, we need only high-quality materials that can withstand the maximum temperature loads up to a thousand degrees. So, the process of manufacturing the housing The boiler consists of such actions:
To make such a hole square form you need to apply markup, then take the electric drill and do the holes in the corners. Next, it is made through the cross-cutting of the angular grinding machine and is conducted from the center to the edge.
In order for the fuel boiler to be as efficient as possible, it should be equipped with two water tanks. They are made on the basis of stainless steel sheets, of which you need to cut rectangles of the desired size and cook with each other. Remember that for welding work It is necessary not only to have a special device, but also put the appropriate skills, or entrust this work to professionals by contacting the profile workshop.
And the heat exchanger is a kit simple pipesthat are used in water supply systems. They are welded with each other so that they are as a result for forming the so-called flow cycle, which has the most allowed exterior area. Thus, it is possible to achieve the most efficient heat transfer between the coolant and the combustable fuel.
It is worth noting that the design heating devices Such is that the metal in them is very much, naturally, it affects their weight. Therefore, the assembly of the finished boiler should be carried out in the place of its immediate installation.
The assembly includes such actions:
Sand for this purpose you need to use well washed, there should be no dirt or any elements of the organic. Before working, it will need to hide on the flame to smell everything unnecessary from it. If this is not done in advance, then when the boiler runs, an extremely unpleasant smell will be formed.
The last stage of work is in the installation of the top plate. All finished stainless steel tanks must be put on the plate on top and connect to the corresponding system circuits. Then you need to put on the place of the door of each bunker and make a trial launch of the unit to check how it works.
One of the requirements that extends to the boilers on any fuel regardless of the place of use is high economy. They also need to have a low thermal inertia and have a function of fast power control.
Also choose heating device On a thom or a different fuel, depending on the locality where you live. The hard fuel boiler is best suited for regions with cold climates and strong winter frosts.
If you want to assemble a solid fuel boiler with your own hands, then with the right approach And the strict compliance of the instructions you will receive an economical heating unit and save huge funds on its purchase, installation and operation.
Homemade heating boiler
In addition to buying the heating boilers presented in the market known and not very global or domestic producers, there is always the opportunity to make the heating boiler with their own hands. And to save at the same time the list of options, without which your heating system can well do. All you need for this - knowledge of the device and the principle of operation of your chosen type of boiler, materials, tools and equipment, as well as practical skills to work with them.
If you wish, you can build almost any type of heating boiler. The main thing is to do right choiceAnd for this you need to know the main advantages and disadvantages of the most sought-after types of heating equipment. AND so, the boilers of heating are:
The manufacture of boilers of this type is not recommended independently: the gas equipment is presented technical requirementsthat you hardly succeed in satisfying in handicrafts.
Pretty high popularity of this category of heap block boilers is explained by simplicity of design and relatively low security requirements for installation and operation.
The design of such a boiler does not differ in high complexity. However, the cost and subtleties of adjusting the nozzles feeding into the combustion chamber will make any at least twice think before reaching the creation of a heating unit operating on a fuel oil or diesel.
- Solid fuel
Representatives of this type are optimally suitable for heating both private homes and various objects of the commercial or industrial sector. High efficiency and versatility in use provide solid fuel boilers the highest demand in the market.
According to the principle of operation, solid fuel boilers differ in wood, pyrolysis, long burning and pellet. The most popular option for self-making is the boilers of long combustion, while pyrolysis and pellets due to the high cost of individual components are much less used.
What does constructive execution depend on?
To which the design of the heating boiler will be, there are several conditions:
- the cost and availability of materials;
- type of fuel;
- the method of circulating the coolant.
The cheapest option for self-making is a wood boiler. Structurally, such an aggregate is two capacities placed one to another. Internal performs the function of the furnace, an external - heating tank. The design of the wood boiler is really simple, and it will be able to work not only with firewood, but also other types of solid fuel.
The design of the wood boiler includes:
- steel furnace (with door);
- asolnik (with the door);
- coopers of firebox;
- susceptor;
- chimney;
- sewberry valve;
- input and outlet nozzles;
- legs;
- pig-iron lid.
Large minus wood boiler - low efficiency, that is, a huge consumption of firewood or a constant lack of heat in the house.
Pyrolysis boilers are more expensive in the manufacture: they have two combustion chambers - for fuel and for pyrolysis gas, and some of their components and themselves are very noticeable. Nevertheless, such equipment is in great demand in mind its economy - it completely pays off throughout 3-4 seasons.
The classic pyrolysis boiler scheme includes:
- combustion chamber with nozzle;
- gasifying chamber;
- air supply system;
- chimney system;
- boot chamber;
- water heat exchanger;
- coolant circulation system;
- temperature and pressure sensors;
- regulatory valve.
Pellet boilers were invented at the end of the 20th century. They function on pressed sawdust, and their basic principle of operation lies in heat transfer from gas allocated during the combustion of the latter, which heats the coolant in the heat exchanger.
The design of the pellet boiler includes:
- housing;
- machine chamber with air window and cleaning door;
- heat exchanger with water contour;
- smoke identifier;
- thermal insulation gasket;
- control and control automation.
In pellet boilers it is best to use cast iron heat exchangers: They have a higher heat transfer indicator and are not subject to corrosion.
How to make an electric boiler?
The main element of the electric heating unit is the thermoelectric heater (TEN) - it is necessary for the transformation of electricity to heat. The electrocotel housing can be made of any material, and the nodes necessary for its operation are regulators, sensors, etc. - can be bought in any specialized store.
Structurally electric boiler consists of:
- Tan;
- expansion tank;
- circulating pump;
- safety valve;
- filtration node.
The coolant in the system can circulate both naturally for which it is necessary to provide a height difference between radiators and a boiler tank and forced with a pump. The easiest version of the electrocotel is the installation of the Tan directly into the heating system. If such a design is not suitable, you can construct an electric boiler with a removable nozzle - it will provide an opportunity to quickly reach the Tan if you need to repair or replace.
The optimal solution for heating, say, a small cottage is a separately located electric boiler of small sizes. The pipe of such a boiler will have a diameter of about 220 mm, and the length of the case is no more than half a meter, which allows you to install it almost anywhere, of course, taking into account the security rules.
The housing of the electrocotel should be sealed. It is supplied with a hole for the receipt of the heated coolant into the heating system, as well as a pipe for the return supply of cooled water.
Alternatives for self-making
In addition to solid fuel and electric boilers for self-making, a number of alternative heating units are suitable:
- Induction boilers
Represent transformers consisting of primary and secondary winding. In such a boiler, electricity on the outer winding is converted into a vortex current, and the created magnetic field is transmitted to the inner, which gives energy to the coolant.
- Condensation boilers
Keep the thermal energy of condensate, therefore they are considered more efficient than gas and even solid fuel. Condensation of steam occurs in a heat exchanger with a special design - it is it that provides such boilers 15-20% of the efficiency in front of traditional gas equipment.
- Liquid fuel boilers
Such aggregates evaporate through the work, after which it burns its pairs. The energy obtained in this way is transmitted to the heat exchanger, which heats the thermal agent heating system. The equipment of this type has two essential drawbacks - low efficiency and a large number of semissions in the atmosphere.
- Combined boilers
This equipment is universal in use, however, for its independent manufacture, there must be short-sighted skills and excellent knowledge of the principles of work. different species Heating equipment. Separate components of such aggregates can cost quite expensive, but in general the combined boilers are capable of paying off for no more than 5-6 seasons.
Solid fuel boilers are the most economical way to heating any room. The availability of fuel, independence from the energy system, simplicity in operation - all this causes the huge popularity of boilers among the population. Unfortunately, not everyone is able to acquire really high-quality equipment, so many of them are looking for how to make a solid fuel boiler for long burning with their own hands - drawings, schemes, explanations and reviews. In our article you will learn how to work for what principles heating equipmentWhat are the features of the structures and their subsequent operation.
All existing solid fuel boilers can be divided into 3 groups:
There are also a number of other classifying signs, but it is the principle of combustion of fuel is determining when choosing a boiler.
In the boilers of this type, the fuel combines slowly with minimal air access, due to which the amount of combustible gas increases and when it is re-combustion, the efficiency of the boiler rises to 85-90%. And although some believe that it is very difficult to make such a boiler with such a boiler, we will also tell me and, most importantly, we will show, usually make a pyrolysis solid fuel boiler for long burning with your own hands (see the drawings).
Constructively, this is a standard wooden furnace, where, due to the smaller cooler chamber, the fuel combines a little slower. As a rule, it is such boilers that prefer to produce themselves. About how to make such a classic unit, you will also learn in the article.
The design of such boilers is noteworthy not only by simplicity of manufacture, but also the possibility of connecting the second circuit to obtain hot water at the same time with heating.
These are the most effective boilers, the efficiency of which is approaching 95%. The main advantage in a fully automatic process, where the pellets loaded into the bunker through the auger are driven into the combustion chamber. Complex design and automation make it independent manufacture difficult.
To date, solid fuel on russian market Presented in a large assortment. It:
In order for the heating to be cost-effective, it is recommended to purchase or produce a universal boiler that can function in any form of fuel. If you decide to purchase such equipment, pay attention to that work on alternative fuels, and switching is carried out very quickly and easily. These may be the following options:
The principle of operation of such a boiler is relatively simple - cold air pulls up, passing through the walls of the chamber, it heats up, rises up and heats the room.
In the boilers of long burning, in contrast to the traditional, air access must be as limited as possible. In order to increase the duration of burning and reduce the amount of free space in the combustion chamber, it is necessary to load the fuel as much as possible and denser.
Required materials and tools:

In order to ensure optimal air circulation, we recommend to fight legs or support to the bottom of the boiler with a height of 25-30 cm. Metal corners or channel can perform as material.
The principle of operation of such a long-burning boiler you can see here:
Video 1 Principle of operation of the boiler model "Slobozhanka"
Video 2 Cowel Long Burning
In the manufacture of the boiler, keep in mind that responsibility for safe work The boiler is mostly the case. For its manufacture, it is necessary to use heat-resistant thick-walled steel, a thickness of at least 5 mm. The thicker it is steel, the slower the case will be heated and the heat is longer.
The fundamental difference between the pyrolysis unit from the traditional lies in the presence of 2 chambers of combustion, where fuel burns in the first, and in the second - produced combustible gas. A grate grid is mounted between these cameras through which the air circulates.
The principle of movement of the coolant through such a boiler is demonstrated in the picture
For the manufacture of pyrolysis boiler, the following materials and tools will be needed:
How it is right and in what sequence to collect pyrolysis boiler, you will find in the video.
Video 3 Production and test of solid fuel boiler 15-25 kW
A solid fuel boiler for long burning can be made with their own hands. To do this, you will need drawings, materials, right calculations and patience. As a result, you will get energy-efficient and inexpensive in maintenance of the heating system, which will definitely work for a decade.
Not everyone knows that the thing created by its own hands is not only less expensive, but will bring a lot of positive emotions to the master. You can create almost everything at home. Be sure to have a drawing, minimum of tools and the necessary parts and mechanisms. One of these things can be a long-burning boiler working with solid fuel materials.
On the Internet, you can view a lot of master classes and video tutorials on the installation of this device. The boiler will warm the winter in the event that its structure will correspond to at least minimal standards. And in this case, information on its creation, calculations, installation of additional snap-in will help.
The boiler should begin to build from ideas. The first step should be the choice of the type of product being created. In some cases, it is possible to choose a view of the existing details, according to the features of the equipment configuration, as well as on the personal needs of the Creator. Only after considering their own capabilities, you should pick up the drawings. In the end, you should choose a long-burning boiler by the direction of fuel combustion direction:
The boilers with the lower direction of burning can be divided into two types:
There are also several options according to the combustion method. The boiler may have a standard fuel absorption scheme. Z.the process is carried out in the same way as under standard circumstances. A bright example is a stove in a private house. The pyrolysis-burning boiler has a special scheme that implies the selection of wood gas with its subsequent ignition.
An important difference is the heat exchanger. This element is manufactured by special technology. There are several ways to solve the issue with its creation. In addition to the features of the heat exchanger, the combustion process can use coal and firewood, or only one of the presented fuel options. In this case, the resonance of using a certain fuel should be calculated in advance. From this choice will depend on the design of the product itself.
The boiler can be done independently, if you correctly pick up materials. Accidentally refer to the selection is necessary at the stage of creating a heat exchanger. The combustion process implies high temperaturewhich affects the state of the metal.
Precisely because modern builders rarely use cast iron. There are many reasons for this and main things:
A bright example will be the cast-iron battery section for heating in the house, which was used during the USSR. Its area is pretty small and is approximately 0.25 m 2. To ensure high-quality heating of the room, you will need a design that is equal to 3 square meters. Twelve separate battery parts are quite large and heavy, and now it is worth only to imagine the design of the boiler.
Also taken into account in the rules and norms. If the boiler is filled with cast iron, the product weight will require the construction of a special foundation. The exclusion method can be achieved by the results of the construction of grids and cast iron, but not as the heat exchanger itself.The modern decision becomes the creation of a heat exchanger of the boiler in production using specially hardened and treated steel. Unfortunately, at home, creating such material will not work. You can handle standard steel with your own hands. But, this material, already at a combustion temperature of 400 degrees Celsius begins to give in corrosion.
The only option becomes creating a heat exchanger of steel boilerbut gradual temperature load. It should be gradually warmed up so that the steel serves a long period of time without the need to replace.
The boiler with the heat exchanger from the steel will be perfectly transmitting heat into the surrounding space, and not to carry it into the pipe. This allows you to talk about an excellent efficiency ratio. On the other hand, the problem arises: the design should not cool too quickly. If the indicators fall below 65 degrees on the Celsius scale, the condensate from the acid will begin to accumulate in the pipe. He is able to damage the cat's pipe for the watch. Fix this omission can be in two ways:
The valve that is used with low-power boilers of long-burning is called bypass. It can be created with its own hands from control from electricity (it will take the installation of a special sensor showing the temperature) or from its own power source. The principle of operation of the valve is simple. The tank has hot water. When the temperature in the reverse of the boiler falls below 70 degrees Celsius, It opens and keeps hot water into the system. It does not affect the combustion process, but allows the boiler to remain integer, maintaining the temperature in reverse system at the proper level.
The boiler with the elevator node has special specifics of the work, namely the reverse technology of the use of the valve described above. In the process of burning fuel, water here heats up to 120 degrees on the Celsius scale. Thanks to the pressure, it does not boil. The combustion temperature should increase, and during the reverse outflow of water it is mixed with hot, thereby increasing its indicators and reducing the risk of forming harmful deposits on the pipes. With your own hands to create something like difficult.
Mandatory condition in both cases is the installation of a circulating water boiler system. The features of the structure of a similar product with long-term burning allow it to build it with their own hands for homework. In this case, you can use the water pump that will not eat from electricity, but from another source.
Selection of material Depends on personal views on the construction of the builder. In some cases, there is only one metal at hand, and therefore it remains to work with the existing material.
The combustion process involves the presence of harmful discharge during fuel combustion. To reduce them, it is necessary to build a chimney in a solid fuel unit, through the pipe of which substances will be disappeared into the world around. Long burning implies more gas secretions, ash and soot. With your own hands, this element is easy to build, if you know its features. That is why it is proposed to consider the drawings in the video of the creation of chimney for the boiler with their own hands.
In addition to the drain pipe itself, it will take a reflector if the boiler is used to heating a small room. Thanks to these elements of the design, with long burning, a solid fuel boiler will produce more heat into the house.
Chimney is created to protect the person from the effects of the components allocated during the burning. Do it yourself to create this design will not be much difficulty, but it is necessary take care of safety rules During the work. A solid fuel boiler for long burning can be secured using a brick laying. It is not difficult to make a masonry with your own hands, because it is only a few parameters differ from the laying of a standard wall. On this topic, a lot of video is represented on the network, and you can master it in just a few views, and sometimes faster.
The drawing of this facility may have different structural features. The main one is not an external perseverance, but really safety. To create a chimney, you will need a pipe, the diameter of the opening of which is at least 1,200 millimeters. A straight plot of pipes with a horizontal surface must have at least 10 centimeters. The diameter should be greater than the output from the firebox of the boiler. With their own hands of long burning, the product must be created with chimney, having at least two bends. Their degree of inclination should be at least 45 degrees.
A solid fuel boiler with long burning with his own hands, the video of which is given below, implies more a few features of the structure of the chimney, namely:
Although the arguments are not aside not towards the cast iron, for most masters, especially at home, this metal remains the only option. Do it yourself installing such a boiler, as described above, will require a master creation of foundation. It will not be much difficult to build it if such works were previously conducted.
The foundation has another property - it protects flooring And the very design of the floor from the effect of elevated temperature. An excellent material will be a liquid brick or so-called boot. These elements do not perceive the temperature, and therefore they do not accumulate heat. You will need only a monolithic plate from these materials to create an additional foundation.
The replacement of this design becomes legs that are welded to the bottom of the boiler. In order to hide them from an extraneous gaze, they are recommended lay a brick.
In such a simple way, you can create a boiler with your own hands. The only requirement to builders is the study of drawing and materials. Attentive video study will allow to get answers to important questions, understand the essence of the work and its specifics, to obtain the final version of the perfect product for heating the room on an ongoing basis or during the visit to the cottage. If you make a cool boiler, then he will warm up not only the body. But the soul. After all, each master must be proud of his creation, whatever it is.
