How to make an efficient stove from an old gas cylinder. Do-it-yourself wood-burning potbelly stove from a gas cylinder Horizontal stove from a gas cylinder

Do-it-yourself potbelly stove from a gas cylinder is designed to heat a house, garage, bathhouse or any other room. This budget option will help you spend the cold winter warm and cozy if you do not have a portable or stationary stove.

What can you make a stove out of?

Such a potbelly stove from a gas cylinder on wood or on a working out can be made in a short time. Indeed, for the construction, you can use almost any of the gas cylinders that you or your neighbors have. A potbelly stove for a garage or apartment can be made from almost any cylindrical metal object. For example, from a can, pan, barrel, bucket, pipe or shell from the time of the war.

But the best thing for its manufacture is an ordinary gas cylinder. This is the most common and easily accessible container made of thick, high-quality metal today. Thickness is important, because a thin wall will quickly burn out, and the oven will have to be thrown out.

In order not to encounter surprises during the manufacturing process, do not immediately undertake to implement the option you saw on the Internet. Calculate it first and see how easy it will be to execute.

Principle of operation

In order for your horizontal wood-fired gas cylinder stove to work normally, you need to build it on the principle of a conventional wood-burning stove. Here is a drawing of such a standard variant built using this method:

In this version, there are two compartments, between which a lattice of refractory material (metal) is reinforced. Firewood is laid on it and set on fire. As they burn, soot is formed, which is poured through the grate into the lower section.

For complete combustion of fuel in a confined space, a constant supply of oxygen from the air is needed, which is provided by the blower. It has special holes for this. But you can also provide oxygen by simply opening the door from time to time.

Smoke exits through the chimney - an equally important part of the furnace. If it is done illiterately and of poor quality, then all the smoke can remain in the room, and the heat will leave through the pipe. You will have to spend a lot of fuel to kindle the furnace, and the efficiency of such a unit will be very low.

The basic principle of operation of a potbelly stove from gas cylinders is as follows:

The blower provides the supply of gas (air) for combustion into the furnace.
In the furnace, complete or partial (depending on the quality of manufacture) combustion of fuel (peat, firewood, coal) takes place.
The chimney removes various particles of unburned fuel, and with them carbon monoxide, to the outside.
To ensure continuous combustion, the process is adjusted using a special damper (throttle) and a view mounted in the chimney.

How to make a heater from gas cylinders

Never use oxygen, acetylene or fire extinguisher cylinders. Processing (cutting) of such containers is dangerous. A small part of the gas may remain in them, which, when cut out by a welding device, may ignite and explode when combined with air.

The stove is made from a durable gas cylinder with a capacity of 50 liters (“red”), designed for propane or its mixture with butane (propane-butane). These gas cylinders are used both in industry and in everyday life.

How to make a potbelly stove from a gas cylinder? Consider sequentially the manufacturing processes of our device.

Preparation of a gas cylinder for the installation of a potbelly stove in it.

The process of making a potbelly stove from the above-described container begins with the preliminary preparation of the corresponding cylinder:

First you need to get rid of the remaining gas. Just open the valve completely.
After the end of hissing (for complete certainty), the gas cylinder can be slightly heated on a fire or stove.
To eliminate a specific "fragrant" additive to propane - a mercaptan fragrance (odorant), it is necessary to completely (to the very "shoulders") fill the container with bleach, which contains acids. It might even be Persol.
Then wait a bit and pour.
After that, soak the insides with a solution of table soda (10%).

What is needed to build

To build our heating unit, you need to prepare the following materials:

3 mm sheet of metal to make an ash pan and (if it is supposed to cook on an oven) a hob;
pipe (you can buy ready-made);
fittings or corner for the grate and legs;
doors (if any).

If there is no last element, it is made from a piece of metal.

The tools needed are:

welding machine for 200A;
Bulgarian (UShM);
welding electrodes;
a hammer;
meter, pencil;
chisel;
roulette;
pliers;
drill, necessary drills;
metal brush;

Which design to choose

A home-made version of a potbelly stove from a container, as already mentioned above, can be horizontal or vertical. It is easy to adapt the hob to it.

The second option (vertical) is installed in a natural position on a stand in the form of a ring with the valve up. It is more difficult to make it, but it has much more traction. Since it occupies a small space, it is often used by motorists for a metal or concrete garage.

The first stands on legs, its valve looks to the side. Make it much faster, and it is advisable to use only in medium and large rooms. Therefore, it all depends on the room where the potbelly stove with a chimney should be placed and on your preferences.

Building a horizontal heater

This potbelly stove is performed like this:

The top with a valve hole is cut off from the gas cylinder.

The grate is made directly in the wall of our heater by drilling it.

Sometimes this knot is done differently. Inside the container (on the walls), corners are welded for laying the grate. If it burns out, it will be easier to pull it out.

The legs are attached (boiled or screwed) to the remaining container. Housing made of sheet material and corners, for collecting soot - welded from below.

A round hole is cut in the wall of the container at the very bottom to insert the chimney pipe.

A hole is welded onto the “collar” of a 5 cm strip. Its inner diameter must be equal to the outer diameter of the pipe.

The door shown in the figure assumes that a cut top with a hole made, an annular belt and a round damper are attached to the hinges.

Another version of the door is shown at the beginning of this section. Instead of a cut off top, a sheet with a welded fitting (for a blower) and a hole for a door is welded onto a gas cylinder. It is strengthened, as usual, on hinges. The valve on the fitting must be of ball design.

At the end, insert the pipe (always with a knee) into the chimney hole:

Making a vertical potbelly stove

Such a design will take up less space, it is convenient to move it from place to place.

Such an oven is started as follows:

A valve is cut out, and the hole (under the pipe) is expanded to 10 cm.
Weld on it, as in the horizontal version - a "collar".
Measure from the bottom up 5 cm and cut a hole for the blower.
At a distance of 5 cm, a hole in the door is cut out.
Between the cut holes (inside the tank) a grill or corners are welded for its installation.
The doors of the blower and firebox are hung on hinges and latches are screwed to them.

Chimney installation

Before cutting a hole for a pipe, find out what kind of pipes you have. After all, the dimensions of standard smoke outlets start from 7 centimeters. Industrial enterprises produce pipes for various chimneys. You can buy any elbows and straight sections required for the construction of a chimney. You can even buy such products from artisans.

The illustration above shows the correct arrangement of the chimney parts. Don't make a straight pipe. This will affect the quality of heating and your pocket.

"Underwater rocks"

The chimney is one of the main components of any furnace. It must be located in such a way that it has sufficient free access.

Due to the incorrect arrangement of elements, it is possible:

smoke in the room;
poor traction;
frequent blockages in the chimney;
too much traction.

Smoke occurs due to:

wrong angle of the pipe when exiting;
the absence of an anti-wind nozzle at its end or low draft, which happens due to a blockage in the chimney;
its small length.

Too much draft is due to the wrong angle of the pipes, and the entry of a large amount of air into the furnace from the blower. All this will lead to a very rapid combustion of your fuel reserves and the devastation of your wallet (after all, you have to buy new firewood or coal). Also, increased draft leads to a rise in heat inside the furnace, and as a result, rapid wear (burnout) of the grate and other parts of the heater.

To eliminate the causes described above, you should disassemble and inspect all elements for contamination. If everything is normal, you need to try to build up the pipe to raise the thrust. If the draft is large, try not to open the blower. If the thrust returns to normal, then you have cut too large a hole. This can be corrected by simply welding part of the hole with a strip of metal.

Gone are the days when a potbelly stove was used for heating residential premises and cottages. Today, only garages and utility rooms are heated with such devices.

The best option for DIY

The main disadvantage of the classic potbelly stove is its low efficiency, which is expressed in significant fuel consumption and rapid cooling after it burns out. Therefore, its converted versions are currently being used. One of the most popular ways to make a gas bottle oven is to use an old gas bottle for this. Its dimensions are different: miniature models of 5 liters in this case are unlikely to fit, since the stove will have limited heating capabilities.

As for cylinders of 12 and 27 liters, the power of the heater made from them is enough to service small areas. Such devices are able to give out no more than 2-7 kW of heat: they are sometimes used as camping stoves. To make a stationary potbelly stove from a gas cylinder for a garage or a summer house, it is recommended to use containers of 50 liters, 85 cm high and 30 cm in diameter. The wall thickness here is quite enough to load any fuel. At the same time, the weight of the cylinder allows you to work with it alone.

There is also an option with industrial gas tanks of 40 liters: with approximately the same volume, they have a smaller diameter (25 cm), greater height and thicker walls. It is much more difficult to operate a freon cylinder - it is both longer and heavier than a household 50-liter container. With the appropriate equipment, it can be shortened to 70 cm: a potbelly stove made in this way will have thicker walls. As a result, it will take more time and fuel to heat it up, but the stove will also take much longer to cool down.

Making doors for a potbelly stove from a gas cylinder

There are several options for arranging oven doors from a gas cylinder:

Cast type finished products. Ready-made modular structures are available for sale, consisting of a blower and flow door. To embed such a module in a home-made stove, it is necessary to cut a niche of the appropriate size in the cylinder body, equipping it with a frame of welded corners. The cast structure is bolted to the frame. The sealing of the cutout under the door is carried out using a small rim (metal strip 10-20 mm wide), welded on the entire length of the body.
Homemade construction. To save money, instead of a purchased door, a home-made structure made from a cut-out piece of the wall is sometimes used. In this case, the presence of loops is also required. The simplest option is to buy ready-made canopies, and weld them onto the surface of the furnace from a gas cylinder with your own hands. Craftsmen make homemade loops using thick chain links for this.

Getting started on making a stove from a gas cylinder with your own hands, it is important to take care of safety. A combustible substance may remain inside the old product in a liquid or gaseous state: therefore, before cutting or cooking a metal container, remove the gearbox and completely bleed off the remaining gas. For fidelity, it is recommended to fill the inside of the balloon with water, and let it stand for a month.

Do I need a grate for the oven

The simplest do-it-yourself drawings of a gas cylinder furnace do not contain a grate. First of all, this is typical for small vertical potbelly stoves, inside which there is too little space for additional compartments. This version of the stove consists of a body with legs, one door and an upper pipe for switching the chimney. To increase the level of heat transfer of the device, its walls on the outside are additionally equipped with welded steel strips. The upper part, in addition to the chimney, has another cutout: if you install a lid on it, you get a convenient tile for cooking and heating water.

In cases where a grate is necessary, a horizontally located cylinder at the bottom is supplemented with a tray for accumulating ash. Vertical stove models from a long-burning gas cylinder are more convenient for installing a grate, since there is much more space in them. To do this, a grid of thick reinforcing bars is placed in the tank itself: finished cast-iron products of the required dimensions are practically not found. The disadvantages of such structures are their rapid burnout and the complexity of repair: for this, it is necessary to cut out the old reinforcement and weld a new one. A more convenient option is to weld fragments of a thick corner or fittings inside the furnace from a propane cylinder as a stand: a separately welded grate is subsequently mounted on it.

Ways to improve the heat transfer of the stove from a propane cylinder

As mentioned above, the main disadvantage of a gas cylinder garage stove is its poor thermal efficiency, because. a significant part of the heat received during combustion simply goes outside through the chimney along with the gases.

There are several ways to improve the heat transfer of a homemade stove:

Apply afterburning of flue gases. In this case, the design of the potbelly stove will resemble the “bubafonya” or “slobozhanka” oven. This will make it possible to increase the efficiency of the device by an order of magnitude.
Extend the chimney. At the same time, part of the heat that goes outside remains inside the room. To do this, the pipe is given a broken configuration, without horizontal sections and negative angles.
Use a smoke outlet. On the horizontally located body of the stove from a gas cylinder on wood, another cylinder is welded in a vertical position: it will act as a smoke pipe. Improving the heat transfer of the stove here is achieved by increasing the area of the heating surface. A prerequisite for avoiding smoke entering the room is good draft.
Arrangement of the heater. This technique is widely used in baths, where quarrystone is used for additional heat accumulation. A metal chimney is equipped with a grid, into which stones are poured to take heat from the pipe and transfer it to the room. At the same time, it will take some time for the stones to heat up: before that, the air will heat up with some slowdown. But in the future, the surface of the pipe will not burn, and the heated stones will evenly heat the surrounding space. Even after the firewood burns out, the accumulated heat will maintain a comfortable temperature in the room for some time.

When choosing stones for backfilling, it is recommended to give preference to round river samples: it is desirable that they have a uniform color without any inclusions. Other types of stones can even be dangerous, bursting when heated, or releasing harmful substances.

Options for increasing the rate of heating the room

In order to quickly raise the temperature in the room where the stove is installed from a propane cylinder, you can use the following devices:

conventional fan. It is mounted in such a way that the forced air blows over the body and the chimney. Craftsmen often go further, equipping the upper part of the cylinder body with through pipes, welding them into pre-shaped holes. On one side of the improvised channels, a heat-resistant type fan is installed, capable of maintaining several speed modes: this makes it possible to regulate the temperature of the air leaving the pipes.
Air vents in the chassis. In this case, additional activation of air flows is carried out without the use of a fan. To achieve this, a wood-burning gas cylinder stove is additionally “dressed” in a special case, in the surface of which there is a series of holes in the upper and lower regions. Through the lower gaps, cold air is sucked in, which usually accumulates in the floor area. Blowing the hot case, the air flows gradually heat up and exit through the upper slots into the surrounding space. Approximately the same principle of operation is used in Buleryan stoves and heaters for saunas.

A simple water heating boiler can be made from a gas cylinder. To do this, a water jacket is arranged around the finished pyrolysis furnace from a gas cylinder: from it, the heated coolant is fed through pipes into the batteries. Such a system must necessarily have an expansion tank installed above the potbelly stove and radiators. Thanks to it, jumps in the internal pressure in the heating circuit due to the expansion of the heating water are compensated. Since we are talking about a primitive boiler without any adjustment, cases of boiling water inside the system will occur quite often. The volume of the expansion tank is at least 10% of the total volume.

Making a potbelly stove from a gas cylinder with your own hands is not a very complicated procedure. During the operation of the finished device, one should take into account the fact that the temperature of its case can reach significant levels: this imposes additional requirements on the fire safety of the heated room.

Modification of the gas cylinder - one of the easiest ways making a potbelly stove with your own hands. In addition, an empty propane vessel can be found in many private houses or cottages. If you have a welding machine, you can easily give it a second life.

Horizontal potbelly stove: instructions

Potbelly stove is easy to make yourself. It takes up little space, is unpretentious to fuel, you can cook on it. But it is important to remember that such a furnace often causes fires. Therefore, it must be installed in a safe place and surrounded by non-combustible materials.

Tools

Before starting work, you need to stock up on the necessary tools and materials:

Empty gas bottle.
Chimney pipe.
Metal sheets (from 3 mm).
Iron bars (reinforcement).
Metal corners or cuttings of a water pipe.
Pipe branch.
Hinges, door handles.
A hammer.
Chisel.
Pliers.
Welding.
Apparatus for grinding.
Drill with a set of drills.
Marker.

Choosing a balloon

For efficient heating need to choose the right size.

A cylinder with a capacity of 5 liters is not enough even for the smallest room. 12 and 27-liter vessels can be used for heating, but in winter the heat capacity of such a stove will not be enough even for a garage. The most optimal is the capacity of 50 liters. Most often propane is transported in these. It has standard dimensions: 30 cm in diameter, 85 cm in height.

If a 40-liter vessel is taken as the basis of the oven, it is important to remember that it has thicker walls and a smaller diameter. This is important because these parameters affect the rate of heating and heat retention.

Preparatory work

There are a number of preparatory activities required so that gas residues do not explode during processing. The scheme of the gas elimination procedure is as follows:

Open the valve, leave the vessel overnight outside for the gas to escape.
Turn the open cylinder over a special container so that condensate can drain there. It has a strong unpleasant odor, so the container with the liquid should be sealed and discarded.
Fill the vessel with water to the top, and then let it drain.
The balloon is now safe to use.

Making a potbelly stove

With horizontal orientation furnace, the bottom of the cylinder serves as the back wall, and a furnace door is made from the lid. Below is a step by step guide:

Using a grinder, cut many small holes on the side surface (or you can just cut a strip of iron). This is necessary so that the unburned fuel residues are poured into the ash chamber.
According to the drawings, make a box for collecting ash from an iron sheet. Its length should be at least 80 cm. Weld a small door to the front. You can buy it in the store or make it yourself.
Weld the ash pan to the furnace body.
Cut a hole in the end of the cylinder for the firebox. Make a door from a cut piece (or buy a finished one), fix it with hinges.
Cut a hole for the chimney (diameter should be between 100 and 150 mm). Twist the pipe itself from a metal sheet. Attach it to the body of the furnace using a special pipe. This element will help change the direction of the chimney, thereby reducing heat loss.
Make grates from reinforcement. In order not to have to weld the grate, iron rods can be bent in the manner of a snake - then pieces of fuel will not slip through the cracks. In addition, in the manufacture of grate, it is important to consider the type of future fuel. Burning with charcoal or wood chips requires narrower gaps than heating with wood.
Attach grates inside the balloon.
From metal corners or scraps of a water pipe, make legs, and then weld them to the main part. The main rule is sustainability. A wobbly stove can tip over and start a fire.

Making doors

A few additional words about the manufacture of doors.

It is most convenient to make a door from a cut piece of metal. So it will fit snugly to the body, which will avoid smoke leakage.
The door must be hung on small hinges. They can also be made with your own hands from several links of a thick metal chain.
From the opposite end, attach a turning handle or valve.
It is recommended to attach an asbestos-cement cord along the edge of the door for sealing.

Optional Details

There are several ways to increase the efficiency of a potbelly stove. They are presented in the table.

way to increase efficiency.	Method
Insulate the chimney.	The flue pipe can not be directed vertically upwards, but bent. So hot air stays longer in the room, which will have a positive effect on heat transfer.
Increase the area of metal contact with air.	To do this, the so-called "wings" are welded to the furnace - metal strips on both sides of the furnace.
Build a tile.	Weld an additional metal sheet above the combustion chamber. It will be possible to put a kettle or a saucepan on it. And if you improve the design with the help of a cover consisting of several circles, it will be possible to control the degree of heating.
Make a brick coat	Brickwork around the stove will increase the heat transfer time, help to heat the room more efficiently. Minus - so the potbelly stove will lose its nominal mobility. But it is not easy to move a heavy structure with a pipe to another place.
Working off.	If you moisten firewood with used oil, it will increase the burning time by 30%. In this way, an unprecedented heat capacity can be achieved.

Water circuit

Another way to increase heat transfer is to install on the chimney water sleeve. Making it is easy:

On the chimney section, install a water circuit with two nozzles.
One of them will receive cold water. It will heat up from the chimney, and then flow back through the second hole.
If you hold the pipe further, install a pair of radiators, then with the help of one potbelly stove it will be possible to heat the entire room.
At the same time, it is better to provide water exchange with the help of a circulation pump.

Additional heat exchanger

An additional one can be attached to the main body. It should be set as vertical branch pipe. This design will increase traction, ensure smooth long-term combustion, and also save the room from smoke, and significantly improve heat transfer.

When using a second cylinder, the chimney pipe should be welded exactly to the top of the structure.

Grids

grate - required element stove designs. It helps to reduce the area of contact between the burning fuel and the furnace walls. In addition, it helps to more thoroughly filter out unburnt residues from coals.

The stove is a necessary and useful device, which is most often used for heating residential premises or outbuildings, cooking and other purposes. Despite the wide range of models that can be purchased today, many people prefer to make them with their own hands.

For these purposes, you can use dimensional barrels or sheet material, but gas cylinders are especially popular, since their use as a basis can greatly simplify the process. The main types of furnaces that can be made in a similar way will be discussed in this article.

Types of furnaces from a cylinder

As already mentioned, you can independently make ovens of various types, below we will consider all the features of the most popular and interesting options:

The potbelly stove belongs to the emergency-reserve type stoves, this is one of the most popular and recognizable varieties. It is distinguished by its versatility and versatility, depending on the volume used to manufacture the cylinder, it can be used both in city apartments and in suburban buildings. The only significant drawback is the short service life, the potbelly stove cannot function constantly, since the thin metal of its base is subject to gradual burnout. However, in case of a sudden power outage, it can become the main assistant for warming up the room.
is made more complicated than a standard potbelly stove, financial resources for this process will also have to be spent much more. However, this option still enjoys continued popularity, which is due to the ability to warm up sheds, garages, workshops and other non-residential premises, without the need to use expensive fuels. With such apparent advantages, there is no mass production of this variety in the factory, since it has been banned by the fire departments. The main distinguishing feature will be the presence of a special fuel tank into which oil is poured.
Bubafonya is one of the most popular options for long-burning stoves. This is easily explained by the fact that its service life is much higher than that of a standard potbelly stove, while the efficiency index is very high, and heat will be released for another day. It is the combination of economy and efficiency that has made bubafonya one of the leaders in its class.
The rocket stove is a very original option. Its manufacture will require a significant investment of time, effort and financial resources, but the resulting device will be able not only to heat the room, it can also be used as a stove bench. The rocket is the best option for people who, for whatever reason, do not want or cannot build a full-fledged brick oven, the consumption of materials for which is several times higher.

Stove potbelly stove from a gas cylinder

Choosing a basis

As you know, most gas cylinders are different, the main criterion for their classification is volume. Therefore, it is on this characteristic that you need to rely on when choosing the basis of a future device, the main recommendations and nuances are given below:

A volume of 5 liters is not suitable, as it will not be enough anyway. for the manufacture of a functional oven that can perform its functions with high quality.
A volume of 12 liters will already be suitable for the manufacture of a universal device, which shows good performance in small spaces. Its power will be approximately 3 kW.
The volume of 27 liters makes it possible to make an oven that can also be used in small spaces and moved if necessary. The power of this option will be about 7 kW, but even this indicator is not enough in some situations.
A volume of 50 liters is the most appropriate indicator, since it will ensure complete burnout of the fuel used. From such a cylinder, you will get a stove with a height of at least 85 cm; you can easily purchase it at specialized gas stations.

Another important criterion is the case material: only those options that are made of solid metal should be used, since composite alloys are too low in heat resistance.

Do it yourself

Potbelly stove from a balloon

Several types of potbelly stove can be made from a gas tank, the following is an instruction, following which will allow you to get a horizontal model:

Place the balloon used as a base in this way so that it is in a horizontal position corresponding to its final shape.
The top must be cut, which will allow you to place a grate inside the structure.
The basis for the lattice will be ordinary reinforcement, while the rod is bent in the form of a snake. For fasteners, it will be enough to fix it in the required place, and then weld it to the walls.
Draw a circle on a sheet of steel, the diameter of which will be equal to the same value of the outer side of the tank.
The marked circle is cut out of the sheet with any suitable tool, after which several holes in the form of rectangles must be marked on it. One will serve as a blower, and the other will supply heat to the fuel chamber. You can cut them with a chisel or grinder, it is more convenient to use the second version of the tool.
Curtains are welded to the lid, after which you can do the installation of the door, in most cases it is bought in advance in the store.
The doors are additionally glued with asbestos cement cord along their entire contour., after which the entire structure can be welded to the main tank.
Now you can move to the back of the potbelly stove, where it is necessary to cut a hole, the dimensions of which will be equal to the diameter of the pipe, it is necessary to remove smoke.
At the final stage, a chimney is welded to the hole made, as a basis for it, a pipe of the appropriate size and sufficiently thick walls is suitable. After completion of this stage, the potbelly stove is ready for operation.

Bubafonya oven

Bubafoni are very popular today, as they belong to long-burning furnaces. They can be made from a variety of materials and fixtures, but using a gas tank for these purposes is the easiest.

Below is a guide to help you through this process:

Cut off the top first gas bottle.
To the part of the structure that will play the role of a cover, you need to weld clamps or stops, it will perform the function of fixing it and fastening it on the device case.
If the edges of the cut part turned out to be sharp, then it is recommended to bend them inward to avoid accidental injury. For these purposes, it is most convenient to use a sledgehammer.
The part that is the lid will also need to bend the edges, but, on the contrary, to the outside. This will allow you to achieve the tightest contact when closing the bubafoni.
Now special attention should be paid to the manufacturing process of the piston. To do this, you will need to prepare a metal pancake with a diameter smaller than that of the cylinder so that it can move freely inside it; a pipe for supplying air to the lower chamber of the furnace; several metal pieces for welding to the bottom surface of the pancake.
A hole should be made in the center of the metal pancake, the dimensions of which will be equal to the diameter of the selected pipe. Several metal elements are welded to its lower part, so that when the piston is lowered, the pancake does not fit too tightly to the firewood, otherwise the necessary amount of air will not flow into the lower part of the bubafoni. It will be enough to have six segments that resemble rays directed from a hole in the center.
The pipe must be cut so that its length is about 6-10 cm, depending on the height of the tank. Then it is inserted into the hole in the center of the pancake and reliably equated to it, while ensuring tightness is not necessary: if gaps remain in the structure, they will additionally contribute to the flow of air into the oven.
In the wall of the cylinder, just below the level of the lid, it is necessary to cut a hole into which a pipe will then be inserted and welded to remove smoke. The recommended diameter is 1 cm, this indicator will be quite enough to ensure normal traction. The length of the horizontal direction of the chimney is about 40 cm, after which it changes direction and rises, the minimum length in this section is 2-3 meters.

Furnace in production

A working furnace or, as it is called differently, an oil garage stove is also much more complicated in design than a classic potbelly stove, but many people prefer this particular variety, since it allows the use of used engine oil and other similar substances as the main fuel, which are essentially waste.

For its manufacture, it is proposed to use the following algorithm of actions:

During operation, the gas cylinder must be kept exclusively in a vertical position. To do this, it is filled with water and half buried in the ground or fixed in a fairly narrow pan, but it must be heavy enough so that the tank does not outweigh it.
Make marks on the top of the balloon and cut it off. For these purposes, a grinder is used, and when a cut is formed, water will begin to flow out, which was previously poured into the tank. It is necessary to immediately stop the workflow and wait until the liquid goes below the cut level, and then finally eliminate the upper part. It must be saved, because in the future it will serve as a fuel tank.
At a distance of about 0.7-1 cm from the cut, it is necessary to make a round hole, it will be required for the installation of the chimney pipe. Its diameter should be equal to the same indicator of the prepared pipe with a total length of about 4 cm. It will need to be inserted into the hole and welded, while maintaining the tightness of the seams.
A vertical pipe will be welded to the horizontal part of the chimney, whose height is 3.5-4 meters.
Now the cylinder should be raised above the floor surface; for its convenient fixation, it is recommended to weld metal legs on the bottom. Similar measures are required to make a square-shaped hole, which will serve as a blower. It will also need to be equipped with a door, which does not have to be made by yourself, but can be purchased at the store. It will be required to manually control the volume of air that will enter the furnace.
It is necessary to lower the fuel compartment to the bottom of the cylinder, it can be easily made from a pipe 7-10 cm high and about 1.5 cm in diameter. At the same time, it must be ensured that it is hermetically welded at the bottom to exclude the possibility of fuel leakage. This compartment will also need a cover, it can be made from ordinary sheet metal material, in which two round holes are made at the same stage. It will be necessary to insert and weld the corresponding pipe into the central hole with a diameter of 1 cm, and place the second hole with a diameter of 0.5-0.7 cm closer to the edge, it will be required to fix the movable cover.
The pipe leading from the mounted cover must be identical in length to the height of the gas tank. A round metal element with the same diameter as that of the main cylinder is welded to its upper end, which will give this mechanism a resemblance to a piston.
The entire piston structure is inserted into the cylinder, while it must be immobilized, so the edges of the cover will be welded to the walls of the tank.
The final stage consists in pouring used oil into the appropriate compartment and conducting the first test of the furnace for mining, this procedure is carried out exclusively on the street. If everything goes well, then the structure can be brought indoors and connected to the chimney system, after which it can be used for its intended purpose.

A rocket stove that allows you to create a heated lounger will be the last option considered. It can also be made on your own, detailed instructions are given below:

Initially, the bed is prepared, this process involves the design and construction of a wood frame. The shape and configuration is selected depending on individual preferences. As a material, it is best to use a beam with a section of 1x1 cm, the frame should form cells with dimensions of 60x120 cm, and the area directly under the stove should have dimensions of 60x90 cm.
A grooved board is used as a sheathing material for the frame., the recommended thickness is approximately 0.5 cm.
All parts and structural elements made of wood, without fail, must be treated with a biocide and several times with a water-based emulsion.
A special kind of cardboard is laid on the floor surface in the place where the rocket stove with sun lounger will be installed, which is made from basalt fibers. The minimum layer thickness is 4 mm, all other parameters depend on the shape and dimensions of the structure.
Directly at the installation site of the furnace, you will need to lay a sheet of roofing iron. The size is selected in such a way that the sheet protrudes outward from the side of the firebox by about 2-3 cm.
The frame is transferred to its permanent place, it must be installed securely enough so that it does not stagger or sway. At a distance of 12-14 cm from the lounger, holes are made in the wall surface, which will be required for the installation of the chimney.
Along the perimeter of the structure, formwork must be installed, the height of which will be at least 0.5 cm. It will be necessary to pour adobe into it and level the upper surface, focusing on the sides of the formwork.
The process of drying the mixture will be long and will take about 2-3 weeks, during which time you can make the basis for the furnace. Initially, you will need to cut off the top of the gas tank to get a hole with a diameter of 20-22 cm.
A steel round is installed in the resulting hole, and a second cut is made below, as a result of which a cover should be obtained, along the perimeter of which there is a thin sheet of steel about 0.5 cm wide.
At a distance of 2-2.5 cm from the welded steel, two round holes are made into which bolts are securely tightened.
The lower part of the gas cylinder is cut off at a distance of 0.7 cm, after which a round hole is made in the bottom, through which the riser will enter the tank. In this case, asbestos cord can be used as a gasket that provides sealing.
After that, it will be necessary to make through holes in the steel casing through the holes in the cylinder and determine the depth of the tank in order to understand the required parameters of the riser. A pipe with a diameter of 0.7-1 cm is suitable as a material for it.
A furnace tank is built into the blower and flame tube at an angle of 45-60°, while the secondary air channel is separated. The riser itself is welded into the flame tube through a pre-drilled hole. The blower is supplied with a door for manual control of the supply of air volumes, tightness is not required.
At this stage, the entire structure must be processed heat-resistant type of lining.
Now you can make a shell, for this a pipe with a diameter of about 20 cm is suitable, from below, a bottom with a thickness of at least 1.5 mm should be welded to it.
An additional layer of thermal insulation is applied to the formwork, and after it has completely dried, a furnace structure is mounted on top.
A hole must be made in the lower part of the shell through which it will be connected to the cleaning chamber. Corrugated pipes are used as a material for the connecting channel, which pass under the lounger.
After installing all the components, you can not wait for all the working solutions to harden and pour about five layers of sifted sand into the shell, moisten it and slightly moisten it. A layer of clay of medium fat content is poured on top.
After completion of all work, the installation of another formwork is required., but already along the outer contour, it will also be filled with adobe in the same way.
Corrugated pipes under the bed at the junction with the furnace elements should also be treated with adobe to improve the fixation of the structure. The covers and doors of all chambers are tightly tightened with bolts.
After 2-3 weeks, the adobe will dry out and you can move on to simpler work: elimination of formwork, coating the structure with special mortars and installation of additional plank flooring. Features of decorative finishes will depend on the personal preferences of each person, after their completion it will be possible to proceed with the first tests of the rocket stove.

Operating rules

In order for the operation of furnaces made from gas cylinders to be safe and not entail negative consequences, it is necessary to know and follow some general rules:

When used to kindle liquid fuels they are not allowed to be added to the stove during combustion.
The cylinder and individual elements of the furnace will actively heat up during operation. therefore do not allow them to come into direct contact with wood or other flammable surfaces.
The chimney must be periodically cleaned, otherwise it will not function properly. It is best to carry out this procedure after each use of the oven.

The chimney must be periodically cleaned, otherwise it will not function properly.

It is recommended to start building a chimney not from the stove to the exit to the street, as is usually done, but vice versa. At the same time, it should be of a collapsible type, which will facilitate the mandatory cleaning process.
Complex stoves are used to heat very large rooms made from several cylinders at once, but it is best to entrust this process to people who already had such experience.
When choosing the type of furnace, you need to think in advance about the issue of fuel extraction. For example, in the presence of used oil, the corresponding type of furnace is well suited, and in its absence, it is better to put a bubafon that runs on virtually any fuel.

A gas cylinder stove can be placed where heating cannot be arranged in another way: in a garage, country house, change house.

If you have the desire and time, you can do all the work yourself.

This article will help you independently convert a gas cylinder into a heating or heating and cooking stove.

Here you will find drawings and instructional videos with which you can make a waste oil, coal or wood stove.

Varieties of furnaces from a gas cylinder

A do-it-yourself gas cylinder stove is considered the easiest option for manufacturing or working out a heating apparatus.

The cylinder is easily transformed into a stove body. To work, you need a grinder and an inverter or any other welding machine.

The shape of the cylinder allows you to make a furnace with a spherical furnace. Firewood in a stove of this form burns slowly - as a result, a kind of heat generator is obtained, capable of heating the room for hours on one tab of firewood.

A homemade stove from a long-burning gas cylinder can be used in different ways:

as heating and cooking in residential premises;
as heating for heating one or two rooms;
as a cooking for use in the summer in the country;
as an emergency portable option for use in case of failures in the main heating system.

Advantages of gas cylinder stoves:

you can get a long-burning apparatus with virtually no cost, since the system is assembled from standard inexpensive elements;
all work can be done independently, no need to look for specialists;
suitable for heating baths;
video materials are available with positive experience in creating furnaces of various designs;
simple operation.

The disadvantages include the moment that the work should be done according to reliable drawings - otherwise the design will not have the required efficiency.

For work, you will need to choose a suitable cylinder. You should opt for an all-metal cylinder with a volume of 12 or 27 liters.

However, for a full-fledged heater, a gas cylinder with a volume of 50 liters and a diameter of 30 centimeters is chosen. Any fuel, including coal, can be burned in a tank of this volume.

Even before the start of work, it is necessary to decide on what type of fuel the furnace will operate. If you need a long-burning furnace, then it is better to provide for the possibility of loading coal into it.

A long-burning stove can be made small, only on wood - for this, it provides for the possibility of regulating draft.

The most difficult thing is to manufacture liquid fuel heating devices: waste oil, diesel fuel. On the other hand, a waste oil furnace allows you to reduce heating costs, since oil is inexpensive.

It is better for a beginner to start with simpler designs, for example, try to convert a gas cylinder into an ordinary potbelly stove.

Solid fuel stove

How can you make a stove from a gas cylinder? The first question that arises even before starting work is: how best to position the tank - horizontally or vertically?

If you want to use the stove for cooking, you will have to place the cylinders horizontally.

In the vertical version, grates will definitely have to be installed inside the cylinder; in the horizontal version, this is done at will.

But in a horizontal structure, it will be necessary to weld a tray for collecting ash, and in a vertical one, when installing the grate to a sufficient height, the ash pan can be omitted.

The potbelly stove will require cast doors for the blower and fuel chamber.

Home craftsmen make them themselves from a piece of metal cut from a cylinder when making a hole for the combustion chamber.

In this case, you only need to purchase hinges and a latch handle. For a purchased door, you will have to weld a frame welded from the corners onto the cylinder along the perimeter of the holes, and bolt the fittings to it already.

Before you start cutting or welding metal, you need to empty the container from the gas. The cylinder is filled to the top with water, then it is drained, and only after that they begin to work.

Stages of manufacturing a horizontal potbelly stove:

cut off the top of the container with a grinder;
install a grate made of bent reinforcement inside the cylinder;
fittings are welded to the tank;
a circle is cut out of steel 4 mm thick, equal to the outer diameter of the cylinder;
holes-rectangles are cut in a circle - the first under the firebox, the second under the blower;
weld a steel circle;
fix doors;
paste over the doors along the contour with asbestos cement;
they begin to re-equip the back of the furnace - they cut out a hole for the chimney equal to the diameter of the pipe;
a chimney is welded from a thick-walled pipe.

When the cylinder is located vertically, a design will be obtained that takes up a minimum of space.

Such a cylinder stove is suitable for a bathhouse, a small living space, it can be put in a garage.

Stages of manufacturing a vertical potbelly stove:

cut off the top of the cylinder with a grinder;
a large hole is cut out on the front of the future furnace for the furnace, below - under the blower, through which the structure will be cleaned of ash;
a grate of reinforcing bars is lowered inside the cylinder and welded to the walls;
a border is welded to the holes under the doors and pasted over with an asbestos-cement cord;
the top is welded - it was cut off only in order to put a grate;
a chimney opening is made from above or from the side.

Bubafonya oven and rocket oven

An ordinary potbelly stove has a significant drawback - low efficiency. A huge amount of heat escapes through the chimney.

In addition, as soon as the fire goes out, the structure immediately cools down. Pyrolysis furnaces are deprived of these shortcomings, that is, devices capable of maintaining prolonged combustion.

The simplest pyrolysis oven can be made from a gas cylinder. Masters call such devices bubaphones.

The bubafonya stove from a gas cylinder was invented by a craftsman from Russia. This happened recently, but bubafonya has already become very popular.

How does the bubafonya type apparatus, converted from a gas cylinder, work? A movable piston is installed inside the container, dividing the balloon into two parts.

Fuel (firewood) burns under the piston, and above it - gases released from firewood as a result of pyrolysis.

This principle of operation leads to the burning of firewood in the "reverse order" - from top to bottom.

Reverse combustion is slower than usual, in which oxygen is supplied to the fuel chamber from below, through the blower holes.

In a bubafon, air is supplied to the furnace by a piston axle, which is a hollow tube. Oxygen enters the pyrolysis chamber through openings cut at the end of the gas cylinder.

The division of the firebox into two compartments allows the wood, even with a lack of oxygen, to burn through to the end without turning into coal.

The system is so effective that the bubafonya from a gas cylinder on one tab of firewood works for 4-6 hours.

There are reliable reviews that a bubafonya from a 200-liter barrel works on one tab for a whole day.

Bubafonya can be used for water heating. To do this, the gas cylinder is enclosed in a water jacket using another metal case, and a water pump is connected to the system.

The rocket stove was developed as a design for survival in extreme conditions. It has high efficiency and maximum safety.

At the same time, a home-made rocket stove is so simple that a non-professional can make it. In rocket furnaces, the principle of pyrolysis is used, that is, fuel decomposes into volatile substances under conditions of oxygen deficiency.

The simplest pyrolysis furnace can be made from any cylindrical metal container, such as a barrel or a gas cylinder.

Rocket stoves can be equipped with benches. Such structures are still used in China and Korea for heating peasant houses.

Structurally, a rocket stove from a gas cylinder consists of a blower, a fuel chamber with a blind cover, a channel for oxygen supply to the pyrolysis chamber, a flame tube in which gases are burned, and a chimney.

Liquid fuel stove

In individual farms, it is sometimes possible to use used engine oil. In this case, heating costs are drastically reduced.

To burn oil, you need to assemble a special furnace that runs on liquid fuel. A mining heater and a simple wood-burning stove work on a different principle.

At first glance, a working furnace is no more complicated than a pan, but complex chemical and thermal processes take place in it.

The furnace for mining from a gas cylinder consists of the following parts:

oil containers;
dampers regulating combustion;
holes for filling oil;
chimney.

For the manufacture of a furnace from a gas cylinder, tanks with a volume of 50 liters are used.

The balloon is sawn in a ratio of 2:1. The smaller part will go to the manufacture of the tank, the larger one will become the afterburner.

The principle of operation of such a furnace system is as follows:

oil is poured into the fuel bunker and set on fire;
air is fed into the chamber through an air throttle and thus greatly limit the intensity of combustion;
as a result, the fuel does not burn, but evaporates, that is, the pyrolysis process begins;
oil "steam" rises to the upper chamber and burns completely there.

In other words, the fuel is used twice - first the oil burns, and then its vapors burn out. As a result, no waste remains, and the efficiency of such a furnace is as high as 80%.

Waste oil is a heavy, heavily polluted and poorly burning mass of complex composition. Two-stage combustion allows you to fully use the entire resource of this fuel. The structure is vertical.

On top of it, you can install a lattice-stand for placing buckets, pans and other utensils.

Drawings that must be strictly adhered to and training videos will help to make a furnace for testing from a cylinder.

The disadvantage of liquid fuel stoves can be attributed to increased safety requirements. Fuel reserves have to be stored away from the boiler room.

A waste oil-powered structure cannot be used as a sauna stove, but it is useful for heating workshops, change houses and residential premises.

In the latter case, it is better for her to build a separate boiler room in the form of an extension to the house.

So, now you know how to make any oven from a metal gas cylinder with your own hands.

Having the necessary drawings, a grinder and an inverter, you can easily make a mobile and efficient heating device that will help out in the winter when other types of heating are turned off or unavailable.
