Do-it-yourself heating boiler: necessary drawings and product features. How to make a solid fuel boiler for long burning with your own hands: drawings and assembly instructions How to weld a water boiler with your own hands

Quite often, for heating private houses are used heating boilers. Almost everyone can weld a heating boiler with their own hands, since these devices have simple design. For the manufacture of the structure, you can use non-professional tools and materials that are available.

Some improvements can be made to the design of the boiler, which will be used for heating your own private house and cooking. Such changes can improve the efficiency of the device.

The design of the heating boiler

This equipment has a similar design with an ordinary stove. The differences are only in the way of heat transfer. The boiler consists of the following elements:

Incineration tank solid fuel.
Grids for supplying air in the right amount.
Water tank or tubular heating registers.
Chimney. It is designed to create the necessary traction and removal of combustion products.
dampers. They are used to regulate the air draft and block the channels after the fire in the stove is extinguished.

The heating system must be supplied with a water heat accumulator. It is a container that is installed in the upper part of the boiler and accumulates heat energy during the combustion process. When this process stops, the liquid will circulate in the system and heat the air.

Additionally, you can install a stainless steel tank, which will contain hot water. It is mounted above the heat accumulator. This element heating system is optional.

The first step is to draw up an accurate drawing of the heating boiler. In order to rationally use the living space, it is recommended to order the development of an individual project of a similar design from specialists.

How to make parts of the boiler body correctly

The basis of any boiler is the furnace, in which the temperature can reach 900-1000°C. To assemble it, you will need materials that can withstand such temperatures. The sequence of actions for the manufacture of the case will be as follows:

If heat-resistant steel is not available, ordinary steel can be used. However, in this case, in order to ensure the durability of the structure, the walls of the node must be made double. The walls must be cut from a sheet of steel using a grinder.
From a steel pipe, it will be necessary to cut the required number of parts that will be used as stiffeners. From a metal corner, you need to make amplifiers for joints between all elements of the stove.
A rectangular hole should be made in the front wall, which corresponds in size to the doors of all bins. In order to make a through rectangular hole of the desired configuration, markings must be applied to the metal, and then the sheet should be drilled in the corners using electric drill. Using an angle grinder, you need to make a through cut in the middle part, and then lead it from the central part to the extreme. In this way, damage to the sheet can be avoided.

In a high-quality boiler for heating, several water tanks should be provided. Tanks should be made of stainless steel. To weld the sheets, you will need to use a special device.

The design of the heat exchanger is a set of water pipes. Using a welding device, they should be connected so that a flow path with a large outer base is formed.

In this case, the fastest and most complete heat transfer from the combustible fuel to the heat carrier will be ensured.

How to assemble the boiler with your own hands

The design of boilers for heating is characterized by high metal consumption. Such a device will end up having a lot of weight. Therefore, assembly is recommended to be carried out at the place of installation of heating equipment.

Under the boiler, it is imperative to make a base of heat-resistant bricks.

After that, it will be necessary to lay the bottom of the ash bin on it. Along the perimeter of this element, the walls of the structure should be installed vertically. After that, the walls are connected by welding.

A diagram of a homemade boiler is shown in fig. one.

Inside the manufactured housing, it will be necessary to lay the grate on the welded guides. After that, heat exchangers are mounted. From the outside, stiffeners must be welded to the hopper in a vertical position, which are made of a rectangular steel profile. At this stage, it remains only to mount the outer walls and the top plate.

Between the walls it will be necessary to fill in the prepared sifted sand, which will perform a dual function:

additionally accumulate heat;
protect the walls of the combustion chamber from possible overheating and accelerated burnout.

For backfilling, it is recommended to use washed sand, which does not contain dust and other foreign elements. Previously, the sand will need to be calcined on fire in order to exclude all organic matter. If you skip this stage, then during the heating of the heating boiler, not the most pleasant smell may appear.

Prepared stainless steel containers will need to be mounted on the top plate, and then connected to the appropriate circuits. After that, it remains only to install the doors in their places.

At cottages and country houses without autonomous systems boiler-based heating different kind not enough. We must pay tribute to manufacturers who offer efficient models with automation and a large range of options. But for heating small country houses or greenhouses, the installation of expensive equipment is impractical, since it will be cheaper to make a heating boiler on your own. According to the main characteristics, it will be no worse than the factory models.

The choice of the type of home-made heating boiler depends on what fuel it will run on. Hence the classification:

TO electric boilers heating does not have high safety requirements. The design consists of a container, which is easy to make from a pipe segment with a diameter greater than that of the inlet pipes of the heating system. Heating elements are installed inside. Despite the ease of manufacture, such a boiler for heating is not economically viable, since the price of electricity is high. Therefore, this option is chosen for periodic heating of small country houses.
For gas boilers high efficiency and low fuel costs. However, due to the explosiveness of gas, the requirements even for factory models are very high. Therefore, it is almost impossible to obtain permission to install and operate a home-made heating boiler, and theoretically when installed in the basement.
There is nothing complicated in the manufacture of a liquid fuel boiler with your own hands. But for normal operation, it will be necessary to install a container for storing fuel oil or diesel fuel and lay an insulated pipeline from it. The price of the burner and the difficulty of setting it up can discourage the desire to make such a boiler. Moreover, you will have to negotiate with the fire inspectorate about obtaining permission to install.
Most often, a solid fuel heating boiler is installed for heating a private house. It is heated with firewood, coal, peat, oil shale. For home-made boilers of this type, the outlet temperature reaches 120 - 150 ⁰C.

The design of a solid fuel and pyrolysis boiler

A traditional solid fuel heating boiler works like a conventional stove. It is assembled from two steel or cast iron containers inserted one into the other. In the inner (furnace) firewood is burned, in the outer (tank) water is heated. The design consists of the following parts:

fireboxes with a door;
grate;
ash pan with a door;
soot collector;
chimney;
gate valve;
branch pipes for connecting the supply and return pipelines of the heating system;
legs;
lids for closing the heating tank.

Outside air enters the furnace through the ash pan and grate. The intensity of combustion is regulated by the size of the door opening. Traction can be natural or forced. A properly designed and made heating boiler has an efficiency of up to 79%.

Advantages of classic solid fuel boilers:

low cost of fuel;
does not require electricity to work;
fuel versatility;
the possibility of burning wood waste.

But when choosing this type of boilers, the disadvantages should be taken into account:

one load of fuel is enough for a maximum of 6 hours;
a place is required for storing fuel;
the complexity of care, since you will have to regularly remove combustion products;
the combustion of solid fuel is inertial, so there are difficulties with regulation.

Pyrolysis boilers for heating, according to the principle of operation, they differ from the classical version in that not only the fuel burns, but also the gases emitted from it. The design consists of the following parts:

afterburning chambers with built-in nozzle;
gasification chamber;
air supply systems;
chimney system with throttle;
heat exchanger;
water circulation systems;
temperature sensor and pressure gauge;
safety valve.

To kindle the boiler, the gasifying chamber is filled with firewood through the top door. After igniting the kindling with an open throttle, a fan is started on the chimney. When the firewood flares up, the door is closed and the throttle is closed. Due to the reduction in the amount of air supplied, the wood begins to smolder at a temperature sufficient to start the pyrolysis reaction. The emitted gases after passing through the nozzle are mixed with secondary air in the combustion chamber, ignite, heating up to a temperature of 1100⁰C, and sent to the heat exchanger.

On a boiler without a smoke exhauster, before adding firewood, open the throttle on the chimney, wait for some time required to remove the pyrolysis gas. After loading the fuel, closing the door and the throttle valve, the boiler continues to operate normally.

Compared to conventional heating boilers, pyrolysis boilers have many advantages:

due to complete combustion, there is no need for frequent cleaning of the ash pan and gas ducts;
ease of control of the intensity of combustion;
duration of work without adding fuel from 5 hours to several days;
the possibility of burning uncut firewood;
the use of scraps from fiberboard, chipboard, MDF and plywood as fuel;
in pyrolysis heating boilers, the content of harmful compounds in the smoke is 3 times less.

However, there are also disadvantages:

Since the fan or exhauster is powered by electricity, an uninterruptible power supply may be required.
When using fuel with a moisture content above 20%, efficiency is reduced.
At low loads, malfunctions are possible, which cause an increase in tar deposits in the gas ducts. To normalize the operation of the boiler, heat accumulators are installed into which excess heat is removed.
To prevent the formation of condensate on the walls of the heat exchanger, which accelerates the corrosion process, the water temperature in the heating return must be at least 60⁰C.
Due to the high material consumption, the costs are 2 times higher than for conventional boilers.

A traditional solid fuel heating boiler works like a conventional stove. Pyrolysis boilers for heating according to the principle of operation differ from the classical version in that not only the fuel is burned, but also the gases released from it.

Do-it-yourself pyrolysis boiler for heating

If you weld a heating boiler at an amateur level, then emergency situations during operation are provided. Therefore, without good skills, it is better not to take a job.

Calculation of power and dimensions of the boiler

Making a heating boiler with your own hands begins with determining the dimensions, which depend on the amount of power sufficient for heating. When calculating, it is assumed that 1 kW of power is needed per 10 m² of heated area. It is easy to calculate that for heating a house with an area of 300 m², a boiler with a capacity of at least 30 kW is required. To compensate for heat loss, a small margin is needed.

It is unlikely that it will be possible to correctly design a pyrolysis heating boiler from scratch without knowledge of heat engineering. Therefore, it is better to find a ready-made drawing on the Internet for the required power. It is desirable that the service life of the unit made according to this project was not 1 year. If necessary, you can contact the author to clarify unclear points.

Necessary tools and materials

To work, you need to stock up on the following tools:

electric drill and drills;
grinder with circles;
gas cutter for cutting large holes;
set of plumbing tools.

As well as materials:

sheet steel 5 mm thick for the manufacture of chambers and 4 mm for the outer skin;
round pipe 57x3.5 for the heat exchanger and 159x4.5 for the hog (horizontal section of the chimney at the outlet of the boiler);
fireclay bricks;
round pipe 32x4.5;
corrugated pipe 80x30x2 and 80x40x2;
steel strip 30x4 mm;
fan;
thermometer and manometer.

The amount of materials is calculated according to the drawing.

Manufacturing process

To save time, it is advisable to chop sheet metal blanks on a guillotine, since it is difficult for a grinder to make a perfect cut. This service is provided to buyers at metal depots. A homemade heating boiler is made in the following order:

A gas and a combustion chamber are welded from blanks.
Air ducts from a professional pipe 60x30x2 with pre-drilled holes with a diameter of 10 mm are welded to the side walls of the gas chamber. At the back, a cutout is made for the chimney.
A tube is led into the combustion chamber through which secondary air will be supplied. It is connected to the front side of the boiler with a 20x20 profile.
The heat exchanger is made from two blanks, in which 2 rows of holes for gas outlet pipes with a diameter of 57 mm are cut. After cutting to size and setting in place, they are scalded.
The finished heat exchanger is installed in place.
Make and install a chimney damper.
The front wall of the chambers is welded with pre-made holes for pipes through which primary and secondary air will be supplied.
At the place where the gas duct exits and the throttle is installed, the back wall and burs are welded.
After cleaning the welds, the inner box is ready.
To fix the outer skin to the box, segments of corners with a shelf of 25 mm are welded.
On the skin in places where the corners are installed, holes with a diameter of 10 - 12 mm are drilled.
Through the holes, the skin is welded to the corners on all sides of the box, except for the top.
To check the tightness of the joints, plug all the holes, pour water through the top. Leaks are marked with chalk.
The air dampers are adjusted with threaded studs. Then the air holes are closed with a casing with an air duct from a professional pipe.
They make and hang doors on the cameras. They are lined with cast iron plates or fireclay bricks.
The bottom of the gas chamber is laid out with sawn bricks.
To fix the fan, a flange is welded to the end of the duct pipe.
The lining of the combustion chamber is made of fireclay bricks.
To improve heat transfer and ease of cleaning, it is recommended to install swirlers (turbolizers) in the gas ducts.
The boiler is tested for leaks with a pressure of 4 bar, which is created by a pressure tester after filling with water. If the pressure does not drop within half an hour, the boiler is ready for operation. Otherwise, you need to look for a leak.
To prevent emergency situations, a safety group is installed on the supply pipeline of the heating system, consisting of a pressure gauge, a safety valve, and an air vent.
If desired, the pyrolysis boiler can be easily equipped with an automatic control system.

Connection and commissioning

Before starting, the heating boiler is connected to an external chimney and filled with water. To control its temperature, a thermometer must be installed. The boiler is put into operation in the following sequence:

Connect the power cable to the fan, check the quality of its work. The air dampers should be in the middle position.
Some paper is placed in the gas chamber, a few poles on top, and the door is closed.
The throttle on the chimney is opened to failure, the fan is started, the paper is set on fire.
After the firewood is lit, the throttle is closed.
Through the lower door, the ignition of pyrolysis gases is monitored. If the torch does not ignite, the amount of air supplied to the gasification compartment is reduced, and the amount of air supplied to the combustion chamber is increased.
When the torch lights up, adjust the intensity of the flame, achieving a white-yellow color with the help of air dampers.
After closing the door, the time until the water boils is noted. At a temperature of 100⁰C, the fan is stopped. The torch should go out.

We make a boiler from a solid fuel pipe

It does not take much time to make a boiler from a pipe with your own hands. Unlike a rectangular sheet steel structure, this option is more reliable, as it is assembled with fewer welds.

What you need to make

Getting started, you need to stock up on the necessary tools:

welding machine and electrodes;
gas cutter;
grinder;
set of plumbing tools.

And material:

a piece of pipe with a diameter of 425 mm for the body, as well as 100 and 25 mm;
sheet steel 4 mm thick;
two nozzles 25 mm;
hinges for hanging doors;
corner 25 mm;
reinforcing bars with a diameter of 8 mm.

Step by step manufacturing process

First, prepare the parts from which the boiler will be assembled from the pipe:

A piece 1–1.2 m long is cut from a pipe with a diameter of 425 mm. This will be the body of a vertical heating boiler.
Two rectangular holes are cut out on the pipe. For a firebox with a size of 200x100 mm, for a blower 200x30 mm at a distance of 50 mm from each other. Doors are made from cut pieces. The distance from the lower edge of the body to the blower is 50 - 70 mm.
On the side in the upper part of the case, 2 holes with a diameter of 25 mm are cut one under the other. The lower one is at a distance of 150 mm from the firebox door for the return pipe, and the upper one is 50 mm from the top of the housing for supplying the heating system.
From sheet steel, cut out 2 circles with a diameter of 425 mm for the housing covers and 1 with a diameter of 412 mm for the partition between the furnace and the tank.
In the top cover and partition, holes are made for the chimney, which is made from a 100 mm pipe.
The legs are made from pipe 25.
A grate in the form of a lattice is welded from reinforcing bars.

When all the parts are ready, proceed to the assembly:

A chimney is welded to the partition and installed on reinforcement supports stuck inside the body at a distance of 300 - 350 mm from the furnace. Then they are welded on both sides.
At the end of the chimney put on the top cover. Both joints are welded.
A grate is inserted from the bottom of the body. Then, segments of the corner 25 are welded on which it will stand.
The bottom cover is welded, and legs 50 mm high are welded to it.
Hinges are welded, the doors of the blower and firebox are hung.

Connection and first kindling

The finished boiler for heating is checked for leaks. To do this, a plug is installed on the lower pipe. Water is poured through the top. If there are no leaks, the boiler is connected to the heating system.

The chimney is best brought out strictly vertically. If this is not possible, it is mounted with a minimum number of bends. Horizontal sections are installed with a slope of at least 0.1% of the length.

For the first kindling, a small amount of firewood or coal is enough. Otherwise, with a sharp increase in temperature, tar deposits will begin on the walls of the chimney. Therefore, due to a decrease in the passage, traction will become worse.

To ensure that a sufficient amount of air enters the furnace, the position of the blower door is adjusted. More convenient for this purpose is a slide gate, which you can buy or make yourself.

Self-welded boilers for heating are not recommended for installation in a residential area, since, unlike factory models, they do not have a guarantee of safe operation. In the event of an emergency, you will have to answer for the consequences yourself. But even when installed in a separate room, fire safety rules must be strictly observed.

Firewood is the most accessible, environmentally friendly and inexpensive type of fuel that has been used by man since the beginning of time. The main advantages of wood-burning heating installations are energy independence, high efficiency with comparative ease of operation. Despite the variety of gas and electric heating systems, wood-burning heating boilers have not lost their relevance and are popular among most Russians. Wood burning plants have one more undeniable advantage- this is a simplicity of design, which allows you to easily make a boiler for heating a house with your own hands. This will be discussed in this publication.

Design and principle of operation

Before proceeding directly to the instructions for creating a homemade solid fuel boiler, you need to figure out how a wood-burning boiler plant works.

In the simplest wood-burning boiler unit with a heat exchanger, during the combustion of firewood, thermal energy, which heats the walls of the heat exchanger (water jacket) and directly the coolant itself. The products of combustion, passing through the soot collector, are removed through the chimney. The draft is regulated by the position of the ash pan door and the chimney damper. The heat exchanger is connected to the heating system, which includes main pipes, radiators and expansion tank. The circulation of the coolant can be carried out, both naturally and forcibly, by including a circulation pump in the heating system (CO).

The simplicity of such a boiler is “compensated” by the low efficiency of this design: most of the thermal energy literally “flies into the chimney” along with the combustion products. But the main disadvantage is low level automation: all operations for loading fuel into the furnace and maintaining the combustion process must be done manually. Therefore, wood-fired boiler plants for pyrolysis combustion are considered the most popular. Making such a heating boiler with your own hands is not difficult for any home craftsman.

Homemade pyrolysis boiler

Fuel is loaded into the fuel chamber immediately in full. Under conditions of lack of oxygen in the gasification chamber, fuel smolders with the release of pyrolysis gas. Smoldering occurs with the release of heat, which is spent on heating the coolant in the heat exchanger. Pyrolysis gas, together with combustion products, enters the afterburner, which in this design also serves as an ash pan. Due to the fact that the access of oxygen to the afterburner is not limited, the combustion of combustible gas occurs with the release of high temperature, as a result of which the efficiency of the device increases significantly. The entire operation of the pyrolysis boiler can be divided into four stages:

At the first stage, the wood is dried and pyrolysis gas is released from the fuel.
The second stage of operation of this installation is the combustion of a mixture of secondary air with combustible gas in the afterburner.
The third stage is the passage of hot gases through the heat exchanger.
Removal of the products of combustion that gave the "lion's share" of thermal energy.

A home-made solid fuel boiler must be equipped with controls and automation that make it possible to simplify and secure its maintenance as much as possible. You can control the operation of the unit by changing the position of the blower door (ash pan) and the chimney damper. The automation of a homemade wood-burning boiler is usually represented by a pressure gauge, an air vent and a blast valve (security group). Quite often, domestic "Kulibins" equip their heating installations with: a temperature sensor, due to which the primary air fan is turned on and off, as well as pressure sensors in the water circuit.

Let's digress a little, because we want to inform you that we have compiled a rating of solid fuel boilers by mode. You can learn more from the following materials:

Preparation of materials and tools

Before answering the question of how to make a solid fuel boiler yourself, you should decide on the design of the device. The simplest option is a classic combustion boiler. In other words, "Potbelly stove" with a water heat exchanger. A more efficient boiler unit is considered to be a classical combustion installation, divided into two chambers: in the lower one, the process of burning firewood will take place; at the top - heating water for the needs of the owner.

After selection optimal design wood heating installation, you should decide on the size of the device. Ideally, the next step in creating a heating boiler with your own hands is drawings that can be ordered from a specialized organization.

Important! We deliberately do not publish drawings of a wood-burning heating system. All information is given for informational purposes only.

Material selection

If you know the art of welding and the possibility of plasma cutting, then to create a wood-burning boiler you need to use sheet metal, 3-5 mm thick. Boiler blanks are cut out of metal, which are welded according to the scheme.

The simplest version of the body is a piece of thick-walled steel pipe, 4-6 mm thick; length 800 - 1000 mm; with a diameter of 300 mm. Grids and supports can be made from reinforcement, rolled metal or channel. You will also need metal to create the bottom of the boiler (thickness 50 mm), cover (thickness 3-5 mm), air distributor (thickness 10 mm), hinges and valves. In addition, stock up metal pipe, with a diameter of 60 mm. The height of the pipe must be 50 mm greater than the height of the body. The chimney will need steel pipe, with a diameter of 100 mm.

To assemble the simplest wood-burning boiler, you will need a tool, namely:

Welding machine.
Powerful angle grinder ("Bulgarian").
Drill and drill bits for metal.

The assembly process can be divided into several stages:

From metal 50 mm, a circle should be cut corresponding to the diameter of the case. After welding, it will be the bottom of the wood-burning boiler.
A circle should be cut out of metal, which has a diameter 20 mm smaller than the body. After that, in the middle of the circle it is necessary to drill a hole with a diameter of 20 mm. A section of the air distribution pipe (d 60mm) should be welded to the hole. On the opposite side of the circle, impeller-shaped plates are welded.
A circle is cut out of sheet metal, 3-5 mm thick, which will serve as the top cover of the boiler. In the middle of the circle, a hole should be made in which the air distribution pipe (d 60 mm) will move freely.
A chimney is welded to the top of the body.

Important! For proper smoke removal, it is necessary that a 50 cm long section of the chimney pipe is strictly horizontal from the boiler.

Fuel is loaded into such a boiler through the top cover. It is necessary to load the space of the fuel chamber as tightly as possible so that there are no gaps. Ignition is done through the top. As soon as the fuel flares up, you should install the air distributor and the top cover in their original places. As it burns out, the air distributor disc will lower, building up pressure in the lower chamber. Due to this, the amount of oxygen in the fuel chamber will be reduced, the combustion process will turn into a slow smoldering. The whole structure of this wood-fired boiler is as follows

Tip: this scheme of a home-made boiler installation requires a chimney. If there is no possibility of arranging a smoke exhaust duct, and there is a need for a heating device, then you can create the simplest induction heating boiler with your own hands if you have a welding inverter at hand.

From a copper wire with a cross section of 2 mm, a winding of 50 -100 turns should be made, the core of which will be a steel pipe. Under the influence of magnetic induction, the pipe section (core) will be heated along which the coolant will move.

Many people associate home with warmth and comfort. If comfort is created due to the diligence of the hostess, then the task of providing the native abode with a comfortable temperature falls entirely on the shoulders of the owner. For this reason, some homeowners decide to build their own heating system. And they do almost everything with their own hands. Sometimes a homemade boiler can be an order of magnitude better than the factory counterpart.

Add warmth and comfort to your home

Types of boilers

If it is easy to decide on the choice of water heating in the house due to the practical absence of competitors, then choosing a boiler is not so easy. There are several types of such units. Here are the main ones:

Solid fuel boilers. The most common and sought after. Works on any solid fuel. They have a high efficiency. Reliable and relatively safe. The disadvantages include labor-intensive maintenance of the apparatus and environmental unreliability.
Gas boilers. Not inferior in popularity to the previous ones, and in some regions far superior to them. Very effective, environmentally friendly, do not require much attention to care. The disadvantages include high fuel consumption and its cost.
Electric heating boilers. Also very convenient boilers in maintenance and operation. The most environmentally friendly, since there is no combustion - no harmful emissions. However, paying for such heating can become an unbearable burden for the family. Electricity consumption is very high, so few people decide to install such a boiler in their home.

In this video, we will consider the heating of the house:

In addition to the main fuel, the design of this type of equipment is strongly influenced by the way the water circulates. It can be of two types:

Natural. In this case, the heating system is made in such a way that the water that fills the system circulates independently through pipes and radiators due to heating in the boiler, and when it cools down, it returns to the boiler again.
Forced. The supply of cooled water to the boiler is carried out using a special pump.

In addition to the pronounced representatives of certain groups, there are a large number of hybrid creatures. Many craftsmen unite different systems heating and create universal projects.

Right choice

To do right choice, the homeowner needs to carefully assess their capabilities and needs, as well as analyze all available home-made heating boilers. What they pay attention to first of all:

Area and volume of premises for heating. The higher the indicators, the more powerful the heater will be needed.
The cost of energy resources. With a limited budget, fuel costs and its cost are calculated. Choose the best option.
Engineering features of the equipment device. If they are going to make a home-made boiler for water heating, then they study its design and assembly scheme well to make sure that there will be no problems with the selection and manufacture of parts and the entire structure.
System maintenance. Get to know how to serve homemade boilers heating of the chosen design, so that later you do not have to face additional problems.
Consumer opinion. They examine the reviews about the boilers of those who have used them or have been using them for more than one year.
Analysis of industrial analogues. Do not immediately discount the samples of serial production. In some circumstances, the overpayment for such a device pays off very quickly.

After weighing the pros and cons, as well as personal circumstances, they usually make an informed decision. The main thing is not to rush and not to take hasty, thoughtless steps. A wise solution to this issue will serve as a guarantee of comfortable living conditions in the house for many years.

Manufacturing scheme

Deciding on independent implementation complex project must remember that the heating systems of a private house with homemade gas boilers not as reliable as industrial designs. Most often they make a solid fuel boiler or electric. Someone decides to combine both options into one.

To make a homemade heating boiler, homeowners should think carefully and draw up a plan of action from start to finish. Here is an approximate scheme of all the main works during the implementation of such a project:

Drawings of the heating system and boiler. They are either borrowed from those who have already made the boiler with their own hands, or they are made independently, calculating all the parameters of the future structure.
Materials and tools. To implement the project, they immediately find and acquire everything the right materials. For the boiler, you will definitely need thick-walled metal (at least 5 mm) or cast iron. Many use pipes, radiators, barrels and other containers made of such metal. Of the tools, the main one for such work is a welding machine with all the ensuing consequences.
Main blocks and details. The manufacture of individual parts and blocks of the future structure begins.
Assembly. At this stage, all the details and blocks are assembled into a single whole.
Examination. After complete assembly, a trial run of the system is made and checked for defects. They are immediately eliminated in the course of detection.
Completion of work. At this stage, pipes and other parts of the structure are painted. If applied brickwork, outer part can be plastered and whitewashed. Carry out design work.

Self-manufacturing of the heating system in the house takes a lot of time and effort. However, such a system can give the owner additional joy from a sense of pride that he was able to carry out such a complex project.

Despite the fact that the modern market for boilers is growing more and more every year, home-made devices for autonomous heating are no less popular. It is difficult to make such a unit with your own hands, but it is quite realistic, and many manage to fulfill their plans.

Advantages of a solid fuel system

Making home-made heating boilers for a private house involves making calculations, as well as obtaining some skills and knowledge. At the same time, the most important thing in such work is safety, since even factory products periodically cause an explosion or fire. Another problem that can accompany the creation of equipment is the interface homemade design with heating system.

Photo 1 Scheme of the heating system at home

most accessible and safe boilers, which can be built on their own, are solid fuel units. They are characterized by the following advantages:

high efficiency;
full autonomy of the system;
simple operation;
environmental friendliness;
low costs.

Solid fuel boilers have the highest level of safety.

There are two types of boilers operating on solid raw materials:

traditional appliances,
pyrolysis.

The difference between them is that the combustion of fuel is carried out differently.

In traditional boilers, there is only one chamber, where the combustion of fuel takes place.

Pyrolysis units have two compartments, in the lower of which fuel is burned with the release of a large number gas, and in the upper - it is burned, resulting in more heat. When operating a pyrolysis boiler, it is required to use only dry wood, as well as comply with other requirements for the heat carrier.

The system of such units is simple and affordable. Such work is within the power of anyone, subject to certain conditions:

possession of basic skills of hot welding;

The main feature of home-made boilers for heating a private house, the video of which we can watch above, is that no special equipment is required to create them, and the structure can be built from improvised means:

sheets of metal, or a metal barrel with a wall thickness of at least 5 mm, while making sure that there are no holes;
radiators.
steel and profile pipes.
dampers.
fasteners.
door.

For the manufacture of boilers, use only new materials without marriage, holes, cracks and creases.

In addition, the boiler can be equipped with a circulation pump.

Drawings and instructions

The equipment should be assembled and installed exclusively according to the scheme, always in the order that was provided for by the drawing. At the same time, errors that lead to the complete inoperability of the product are completely excluded.

Traditional home-made boilers for heating a private house, the drawings of which can be made independently, are made in the form of 2 compartments, placed according to the “matryoshka” principle. The outer compartment will act as a chamber for fuel combustion, and the inner one will serve as a tank for heating the coolant. At the same time, these compartments should not communicate with each other so that combustion products do not fall into the water.

After assembling the base, a home-made boiler for heating a private house, the drawing of which makes it possible to do this quickly and correctly, is installed in a permanent place. Then the firebox is equipped with a chimney with dampers so that the smoke is expelled outside and heating is provided. In conclusion - giving the stove aesthetics using bricks or decorative elements.

Next, a home-made boiler is connected to the water circuit and the first inclusion of the structure is carried out, which is a test run. In case of successful testing, the product can be used for its intended purpose.

Homemade boilers are a good solution for heating a house at any time of the year, because they can become part of the interior, the pride of the master and a source of heat.
