Parts to significantly increase combustion and heat capacity
Pipes in the manufacture of a furnace operating on waste oil are not the only necessary element. It is important to ensure an optimal long-term combustion process. For a furnace that runs on waste oil, a special suspended weight is ideal. As the fuel burns, it will press the load against the grate by its gravity. A metal pancake with a hole can be used as such a load.

Stone can be used as elements that provide heat capacity.

Here you can note the following execution options:

1. If the furnace runs on waste oil, a lining with special refractory plates is optimal. It is ideal because the metal body wears out much less, and the volume of the firebox is preserved;
2. Another method is based on covering all the walls with bricks. As a result, you can get a furnace that runs on waste oil;
3. There are drawings of oil-fired stoves that have an open box in their upper part. A stone or brick is laid in it.
4. Very often, a potbelly stove that runs on oil is designed in such a way that there will be a mesh on both sides to firmly fix the stones.

Summing up

This article described the main points for making stoves that run on oil. If you know all the main points of their manufacture, you can quickly make a potbelly stove yourself.

These are just the basics, but there are also numerous additional details, such as legs, handles for moving and protective screen. These details usually reflect the drawings, so everything will be as easy and simple as possible.

A potbelly stove is a compact iron stove with a chimney at the top. It consists of a chamber into which it is poured solid fuel, a grate in the form of a metal grate, a pipe - a chimney and an ash pan for collecting ash.

If you know how to handle a welding machine, the device is easy to make, and at the same time, it will serve faithfully in unheated room, in field conditions, in the absence of centralized heating, for decades.

How to do it yourself?

Manufacturing options:

Rectangular oven

It is a metal box; you can independently weld the structure from steel sheets. For a rectangular potbelly stove, an old car tank or box will do just fine.

Typically, this form is chosen when it is necessary to cook food on the stove.

On the spacious platform you can place 2 large pans or containers for heating water at once.

The manufacturing principle is simple: doors are built to cover the ashpit and combustion chamber, a hole is made for the chimney, combustion products must leave the room in a timely manner, otherwise you can inhale carbon monoxide.

From a gas cylinder

The most common type of potbelly stove. The cylinders have thick walls, making the stove durable, mobile, and fireproof.

First, a drawing is drawn and markings are made. The combustion chamber door will be located in the center of the cylinder. The blower is in the same plane, only 10–12 cm lower.

Instructions:

1. We take an angle grinder, cut out both doors, draw a closed line between them.
2. Along the line cut the balloon into 2 parts.
3. At the bottom We weld the grate - the ash pan.
4. Install grate, weld both parts again.
5. For valve make a hole with a radius of 10 cm.
6. For hood insert a hole into the pipe, weld objects together by welding.
7. Simple stove from the cylinder is ready, you can use it, add fuel and check its operation.

For cooking on the top of the stove, the design is slightly different:

1. Cut off the top of the balloon.
2. Inserted inside and the rods are welded.
3. Top side a hole for the pipe is cut. You can heat and cook food at the same time.
4. The hole is welded, the valve is screwed in, a comfortable handle is adjusted.
5. From the pipe, barrels can also be made into a furnace. The barrel or pipe must be selected according to its diameter.
6. Below the barrel pipes, cut 2 holes for the firebox and ash pan.
7. Make the doors.
8. Do framing holes made of metal strips.
9. Under the fire door At a distance of 10 - 12 cm inside the barrel, weld brackets in the corners, the grate will lie on them, pre-weld it from any fittings.

When making a stove from a pipe, weld the bottom, as well as the part on top:

1. Down to the bottom weld 4 legs.
2. On a surface cut a hole, weld a pipe to it, this will be a chimney.
3. Weld the hinges to the previously cut holes, install the doors. Also, mark and attach a hook so that the doors lock tightly.
4. For design aesthetics process all welding seams, clean them 10. Paint the outside of the device with heat-resistant paint. Whatever the factory product, you can sell it or successfully use it yourself.

Working furnace

The option is distinguished by a specific odor that oil waste will emit during fuel combustion, even in the presence of an exhaust hood.

Instructions:

1. To make this model, pick up sheet material at least 4 mm thick, a chimney pipe, and individual small structural elements.
2. Do it on a sheet precise markings of all elements, having previously drawn a drawing.
3. Embed all elements with a grinder, clean the edges of the parts. Drill holes round shape in the pipe.
4. Top of the tank cut a hole for the pipe off center to the left.
5. Offset to the right Drill a hole on the circle for the connecting pipe.
6. It turned out to be 2 circles, weld them to the pipe; the thickness of the upper tank will depend on its length.
7. Decorate the bottom part of the stove in the same way., but now cut the hole right in the center of the marked circle.
8. Cut side by side second hole, attach the sliding cover to it.
9. Weld to the bottom plane 4 legs.
10. Clean seams after welding, paint the surface with high temperature resistant paint.
11. Connect the chimney to the stove. The waste will be poured into the lower part of the tank; after the paper is ignited, the sliding lid closes and the waste begins to burn. Oxygen will penetrate through the holes, and the waste will burn intensely.

Necessary materials, tools

Before starting work, prepare the tools:

• metal brush;
• chisel, pliers, hammer;
• tape measure, chalk;
• drill with metal drills;
• sander;
• metal circles;
• welding machine;
• protective mask;

For the body you will need a pipe 30 cm in diameter, at least 5 mm thick. You can use sheet metal of the same thickness instead of a pipe.

For the chimney, you should select a pipe 12 cm in diameter, with a thickness of at least 3 - 4 mm. To prevent burnout, a metal box is suitable for the ash pan, so you need to choose durable sheet metal.

Step by step guide

First you need to cut the metal, taking into account the thickness and length of the required blanks.

Remove the chamfers from the parts, touching the stove will be safer, and the welding seams will be stronger:

1. Check that the parts are correctly marked before you start cutting them. When cutting, take into account the thickness of the oven walls, as well as the thickness of the circle.
2. Remove the chamfers from the prepared parts for safety from accidental contact with a hot device.
3. Check all part markings.

The structure is installed in the following sequence:

1. Connect welding machine to the network.
2. Take electrode with a thickness of 4 - 5 mm, taking into account the sheet or pipe.
3. Install current on the device is up to 160 A.
4. Put it on special glasses and overalls, protect your hands with gloves.
5. To the bottom of the oven weld three walls.
6. Bottom of the device place it at least 5 cm from the floor.
7. Connect parts at right angles. Check their perpendicularity with a level.
8. Where you need it, straighten the corners of the parts.
9. Weld parts and joints relative to the floor level, at an angle of 45 degrees.
10. Weld a partition between the ash pit and the firebox, having previously cut holes so that ash does not accumulate.
11. Endure the distance between the holes is at least 5 cm from the walls of the stove. The distance between the partition and the bottom of the structure must remain at least 10 cm.
12. Last but not least by welding, cut holes for installing the chimney on the rear panel homemade stove.
13. Make your markings, drill rectangular holes in the places intended for the firebox and ash pan.
14. Combine with a partition all the lower parts of the holes. The distance between the walls of the firebox and the upper side edges should be at least 3 - 5 cm. The opening for the vent is slightly smaller, but not more than 5 cm.
15. Bulgarian cut two holes from metal and form doors. Weld them onto the canopies, raise the blower as much as possible to the top of the slab opening so that they do not sag in the future under the influence of high temperatures.
16. To the doors Weld the bolts, they should open and close easily, without obstacles.

After all welding work, check the quality of the seams and tap them. If there are defects, correct them immediately. At the end of the work, weld top part devices.

How to make a long-burning potbelly stove?

To ensure that the potbelly stove radiates heat for as long as possible without adding another portion of firewood, and does not burn out quickly, the fuel will not burn, but will smolder, the heating process without adding firewood can be extended for several hours.

Manufacturing a furnace for long burning slightly different from the usual design.

The best cylinder for the stove is:

1. Cut the top off of it, this will be the stove lid.
2. Make a hole at the top and side of the stove, this will be the hood.
3. Make a hole in the center so that the balloon can be easily inserted.
4. Weld to the cut hole of the pancake a pipe, slightly longer than the cylinder. The pipe will serve as a blower, and oxygen will flow into the furnace, and the fuel will not smolder and not burn.
5. Cut off part of the cylinder in the center, insert a pipe into the hole as a blower. The operating principle of a long-burning potbelly stove is to create pressure inside the chamber. After the firewood ignites, a heavy metal circle plunges inside and begins to put pressure on the fuel, creating pressure on it, the fuel begins to lack oxygen and slowly smolder. The smoke, going upward, comes out through the chimney, the room will not be smoky.

Advantages and disadvantages

Like any other heating device, the stove has both pros and cons.

The undoubted advantages of a homemade stove are:

1. Compact size.
2. Use of any available fuel, can be heated with peat, firewood, sawdust, wood chips, and coal.
3. Low cost of manufacturing the device, you can basically make do with handy materials.
4. Installation of the structure does not require laying a foundation or chimney.

The disadvantages of the stove include:

1. Fairly high consumption fuel material, the principle is this: while you heat it, it’s warm. To keep the room from cooling down, you need to add fuel more often, otherwise you may simply freeze.
2. Furnace walls become very hot and can cause burns if they come into contact.
3. Can't be allowed coals falling out of the stove can cause a fire.

Where can it be used?

Stoves were popular in the first half of the last century. They warmed the soldiers' dugouts, dugouts, and heated carriages.

Today the stoves are still heated garden houses, garages, warehouses, greenhouses, that is, where there is no gas pipeline, and electrical devices They are ineffective and burn a lot of electricity.

Types of homemade potbelly stoves

The material for the construction is cast iron or stainless steel. The stove consists of a container, an ash pan, a pipe, a chimney, and a combustion door.

They are distinguished by type:

• pyrolysis furnaces;
• with a cooking platform on top for cooking;
• furnaces lined with a casing for efficient heat transfer. For homemade products you can choose old cylinder, barrel, large vat, can. Furnaces can be cylindrical or rectangular in shape;

Installation safety rules

Any homemade heating device is designed to heat the room, making it more comfortable, but at the same time, such devices are far from safe and are fraught with ignition and fire.

When installing the structure, it is very important to follow safety rules:

1. Bake must be installed on a fire-resistant surface, otherwise the floor may burn out. To do this, it is good to lay brick or tiles on the floor.
2. Stove walls should not overheat too much; for this purpose, special plasterboard or other non-flammable material is used in production.
3. Highly flammable materials Do not place it near the firebox, it may catch fire.
4. Take care about ventilation in the room where the potbelly stove will be located. Carbon monoxide must escape outside in a timely manner and not accumulate inside the room.
5. Use in production only high-quality, fire-resistant material.

1. If there are panel or wood walls in the house install the stove at a distance of 1 meter from them.
2. Be sure to mount chimney preferably from one section.
3. When passing a pipe through a wall install a brick thermal barrier. Do not use concrete for these purposes; it crumbles quickly.
4. For garage would be better suited The potbelly stove is being worked on, so don’t rush to throw away the car rims.
5. Don't put on the stove near flammable materials.
6. Pipe section It is above the roof that is made of non-flammable material, so the stove will cool much more slowly.
7. Think it through ventilation system, there should be no burning in the room.
8. Lay out the floor and walls near the structure with a brick, or facing material, the stove is a fire hazard. The same applies to the chimney; the distance to the walls and ceiling must be at least 1.2 meters.
9. Set for security purposes metal fencing around the device.
10. grate It’s better to make them from cast iron grates in a set, so they will be easier to pull out of the firebox.
11. Install all chimney parts only at the top of the structure, they must withstand high temperatures over 300 degrees.
12. Treat seams after welding with durable and high-quality sealant.
13. Do not clean the pipe with a brush, metal objects, the pipe walls can quickly become leaky.
14. Installing a chimney, make an anti-rain canopy, rain moisture will not get inside the pipe.

A potbelly stove made from a horizontal pipe is one of the simplest but most productive designs of homemade stoves that burn solid fuel. The simplicity of the design and low cost allow even novice home craftsmen to make such a stove.

Collapse

First, beginners need to understand how the stove works and what parts it consists of.

Principle of operation

The operating principle of such a furnace is simple:

• firewood is placed in the firebox;
• for kindling, thin wood chips are placed closer to the door;
• the door in the ash pan and the slide valve must be open;
• the wood is set on fire and the door must be closed;
• the flame heats all surfaces of the oven. The metal, giving off heat, gradually warms the room;
• For the second filling, you can use coal or waste from a carpentry shop.

Stages of work

Before starting work, it is necessary to determine the size of the furnace and prepare the necessary materials, tools and welding equipment.

Drawing and diagram

Drawing of a potbelly stove made from a horizontal pipe

Another version of the drawing

The simplest pipe stove runs on solid fuel and consists of several main parts:

• body - it is made in different shapes, depending on the materials used for its production. It can be rectangular when used sheet metal or cylindrical, in this case the body is made of gas cylinders or large diameter pipes;
• grate. It serves to protect the bottom from burning and remove ash to a special compartment;
• ash pan - wood ash is collected in this part, this cavity serves as an ash pit to improve draft when firewood burns;
• combustion chamber. Firewood or coal is placed here;
• for withdrawal carbon monoxide stoves are equipped with a chimney pipe outlet. In some cases, it is discharged vertically from the top of the furnace or with an outlet extending from the rear plane. But in any case, the chimney outlet is located at the top of the structure;
• A reflective screen is installed above the door. It is placed along the entire plane of the furnace, leaving an air passage in the rear cavity. In this case, the heat does not immediately go out into the chimney, but passes through the stove, heats the walls and only then enters the pipe;
• combustion chamber doors. Here they use ready-made cast iron or steel doors or homemade ones from a piece of thick metal;
• the most efficient potbelly stove is equipped with additional convection pipes; drawings of such a homemade stove can be found on forums on the Internet or check out industrial ovens Professor Butakov or the Bullerian model.

A potbelly stove made of a pipe with an internal diameter of 500 mm is made according to the drawing, taking into account the main dimensions of the structure:

We will take the dimensions of the remaining parts and their installation locations from the drawing.

Let's look at the process of making a homemade stove.

What kind of pipe is needed?

Any pipe can be used. The most important thing is that it has not been previously used on gas supply pipelines and for sewerage. Such stoves, together with heat, will spread unpleasant odors throughout the room for a long time. In terms of size - it all depends on the needs and capabilities of the master.

For heating small garage It will be enough to make a stove with a diameter of 400-500 mm. For a large room, you can make a potbelly stove with a larger diameter or install several small ones. The main thing before work is to clean the walls from limescale, dirt or oil and only then start working.

Materials and their quantity

To produce a potbelly stove we will need to prepare:

• steel pipe with a cross-section of 550 mm, with a wall thickness of 10 mm - length 650 mm;
• for the top of the stove from 4-5 mm steel, we cut out a blank 700/420 mm and bend it along the length of the shelf, marking 40 mm from the edge of each side;
• front and back wall potbelly stoves - 2 parts, size 560/560 mm;
• for the reflective screen, we cut out a blank from a sheet measuring 500/420 mm;
• for the grate you will need to prepare reinforcement with a cross section of 10 mm - 2 pieces of 600 mm each and 32 pieces of 380 mm each;
• for the chimney outlet we prepare a piece of pipe with a cross-section of 100 mm and a length of 260 mm;
• At the top there is a burner for cooking. You can use ready-made cast iron or make it from a steel sheet 12-14 mm thick, cutting out a circle with a diameter of 220 mm with a plasma cutter and grinding the workpiece using sandpaper or a grinder;
• from a 40 mm profile we prepare 4 legs 400 mm long;
• we buy ready-made hinges or you can make them yourself from a profile and a rod;
• for the door we cut out a blank 340/340 mm from the sheet;
• 6 pieces of corner for laying the grate.

This is a list of basic materials; small parts will be made during the work process.

Tools and equipment

We will need:

• a set of locksmith tools;
• welding machine with clothing and eye and hand protection"
• grinder with cleaning and a supply of cutting discs;
• workbench with a vice;
• sand for filling the bottom of the oven.

Step-by-step manufacturing instructions

Having prepared the entire set of tools and materials for work, we begin the process of making a potbelly stove from a pipe with our own hands:

1. We place the finished pipe section on flat surface, set the protective screen at a distance of 5 mm from front side and grab it to the pipe. Here it is important to have experience in performing ceiling tacks, although there is practically no load on the screen. We place tacks every 60-80 mm.
   
2. At the bottom of the stove we retreat 50 mm, mark longitudinal lines along the entire length of the pipe and grab the corners for laying the grate. To make it, we place long parts from reinforcement, insert the jumpers along the edges and grab them. Now, retreating 10 mm from the jumper, we join the next jumper. Thus, we assemble a grid from reinforcement, measuring 600/400 mm. After this, turning the grate over, we place oven mitts on the reverse side.
3. We put the grate in place and join the sheets of metal on the front and back sides. Distortion and large gaps between the sheet and the pipe must not be allowed. If the pipe is cut crookedly, you will have to straighten the workpiece by grinding the walls with a grinder. Having checked the correctness of assembly, we proceed to welding the joints. The seam must be airtight, so after welding, beat off the slag and boil the burnt areas, holes and lack of penetration.
   
4. There is another option for installing a grate that is more practical. A rectangle with small indentations along the edges is cut out at the bottom of the pipe, a blank from profile pipe(for collecting ash). A grate is placed on top. This is what it looks like:
5. We grind the protruding corners and the joints of the parts with a grinding stone. Then we turn the workpiece face up and mark an opening for laying firewood. We put a cutting disc on the grinder and cut out a groove according to the markings.
   
6. We remove the burrs with a file, lay out the door with a welded handle and latch and install it on the finished hinges. On the sheet we place and grab the counter part of the lock, and on the door we place a homemade lock - a latch.
   
7. We turn over and place the potbelly stove bottom up, mark and weld the legs from the profile pipe, having previously cut the corners for better joining to the body. At the bottom, we cut the legs at a slight angle and weld nickels from the sheet for better stability of the potbelly stove.
   
8. We install the stove on its legs and place a blank with holes for the chimney pipe and burner on top of the stove. Having placed it with the curved edges down and checking the correct installation, we grab the plate.
   
9. Using electric welding, we burn holes in the pipe and install a pipe with a diameter of 120 mm for the hood and pancake for pans.
   
10. The parts are scalded in a circle, the joints must be airtight. At the end of the ventilation pipe we weld a damper to regulate draft.
11. Having opened the door and installed the grate in place, we fill the bottom of the oven with a layer of sand.
    

The stove - potbelly stove made from a pipe is ready.

Look at a few more manufacturing options to reinforce your understanding:

Features of operation

When test-running a potbelly stove, it is better to open all doors and windows. We make sure there is traction and an open damper. Then, placing firewood through the door, we light the flame. We close the door and go outside. The potbelly stove will smoke a fair amount, but you should not be afraid of this, it will burn out oil and other debris.

Combustion process

After using the oven for the first time, it may be necessary to repair welding defects. And then enjoy the warmth in the garage or other room. The main thing is to remember the rules fire safety, periodically clean the chimney and remove ash, periodically replacing the sand in the potbelly stove.

Conclusion

Even a novice craftsman can easily make such a design on his own. The main thing is to want to make a reliable potbelly stove and carry out all the work carefully and responsibly, taking into account the step-by-step instructions given in the article.

In Russia, then the USSR, potbelly stoves were used where there was no centralized heating: in front-line dugouts and dugouts of the Great Patriotic War, in government institutions of the same time, in heated cars. Look at the photo of a potbelly stove made by yourself on the website.

Who are the authors of homemade products?

Many Russians are sure that this is only a simple Russian invention. And a few are wrong. In the USA, the same homemade products have been used for centuries, called “fat bellies”, in Japan - “daruma”.

The revival of potbelly stoves occurred in Russia in the second half of the 20th century due to the massive appearance of garages, garden plots, where they were the only means of heating thin-walled buildings.

After these mini-ovens were improved, they were also used for cooking: a pot or frying pan was placed on a stove attached on top.

Until they were replaced by a centralized supply of methane, gas-cylinder stoves or wood-burning brick stoves. They were also useful in the crisis years of the 90s due to interruptions in gas and other types of fuel. It’s good that at least there was plenty of firewood.

What is so attractive about a potbelly stove?

Its main feature is its simplicity of design. Even with many additions to it, the principle of operation of a metal stove remains the same: everything that is at hand burns and warms the summer residents.

Although in this case half of the thermal energy evaporates through the direct-flow pipe. But no one writes off even a heating source that has rusted over time as scrap.

Such a temporary stove can be easily made in a day or two. But first, make your own drawings of the potbelly stove. Much of what is stored in the closets of rural houses and dachas is used. These are milk and water metal (not duralumin) cans, barrels for diesel fuel, vegetable oils, pipes, boxes, corners.

Nothing expensive, including tools - in villages every owner has them at hand. High-quality assembly using gas or electric welding.

But neighbors who have units will help with this. Welding machines provides greater reliability and rigidity of the assembly. How to make a potbelly stove with your own hands, step-by-step instruction below.

Making a potbelly stove from a steel can

Stock up on a hardened chisel, a hammer, a chimney, a piece of rod with a diameter of 0.6 - 1.0 cm. Prepare an electric drill with a drill one centimeter in diameter. If you have an angle grinder, you will speed up the assembly twice as much.

In one part of the cover, at the very bottom, drill 5 - 7 holes for future traction. Bend a long rod like a snake and with at least four legs. These will be the grates when you insert them into the can.

Straighten the snake inside so that it lies horizontally and firmly just above the holes. Wood will burn on this “grill”, and good air draft will flow through the holes and through the chimney. It will be a combustion catalyst.

For the chimney, use a piece of water pipe, even a used one, with a diameter of 7-8 inches. Near the bottom or at the very bottom, strictly perpendicular to the grates, cut a circle with a chisel or saw with a grinder.

Insert the pipe a few centimeters into it, and secure it firmly from the outside with a clamp on the bolts or weld it to the can. The can-stove is designed for a horizontal position.

Weld the legs to it and place it where the potbelly stove will heat the house or garage. This is a very flammable device, so place it on a metal sheet and at least half a meter away from wooden structures.

The disadvantage of the stove: you can’t even heat a kettle on it – there’s nothing to put it on. And yet it will be an effective potbelly stove with your own hands, and read about the improvements below.

Barrel stove

It will correct the situation, and on this potbelly stove you can even cook borscht and fry cutlets. Not only an old barrel will do, but it’s better if it’s a discarded 50-liter gas cylinder.

Its walls are thicker, they will heat up a little longer, but they will also retain heat more. This is an ideal sauna stove. And if you cover it with sea or river pebbles or other strong stones, it will be easy to raise steam in the room.

It will stand vertically. There will also be enough space for the blower, and you can put a lot of firewood in the firebox above it. You can make the exhaust pipe not straight, but with elbows for greater release of thermal energy in the steam room.

If a potbelly stove is needed for country house, then weld a metal platform on top, and you will cook food and tea on it.

Preserving heat in a potbelly stove

To do this, it is necessary to cover two thirds of its parts with refractory bricks, placing them on horizontal ribs, leaving free access to the firebox and ash pit. This will be a heat shield that retains the generated energy much longer. Holes must be drilled in the bricks for better heat transfer.

Second option: potbelly stove plus water heater. Scald the gas cylinder from which the stove is made with sheet steel at least three millimeters thick.

So that the resulting container can hold at least 30 liters of water. Weld the water inlet and outlet pipes to it, connect the pipelines for heating the next room. For better convection, connect a small circulation pump.

Propane stove

The ideal stove - gas stove, made with your own hands. She doesn't need chimney, because no smoke is released when the gas burns. Its analogue is indoor gas stove with oven.

It’s not difficult to make - take... a ready-made potbelly stove, insert a steel pipeline into it with a nozzle from an old one gas stove. Connect it to a standard gas hose with a reducer from a household gas cylinder.

There is no exact cost for a potbelly stove; you can use a 4-burner stove as a guide. The capacity of a cylinder (50 liters) with 21 kg of propane-butane is enough for 34 hours of operation of such a stove.

DIY potbelly stove photo

The design of the potbelly stove, which became widespread back in the 19th century, has not lost its relevance today. At the dawn of the last century, it served as the main method of heating in residential areas where it was not possible to install a stationary stove. With the advent central heating The popularity of the potbelly stove has decreased, but during the war, and simply in army field conditions, the help of such a stove is irreplaceable.

Types of homemade stove

The choice of the most suitable stove design depends on the location and purpose of its operation. Is your garage your second home and do you spend all your free time in it, regardless of the weather outside? The optimal solution would be to make a furnace that uses spent fuel. Have you decided to get a potbelly stove at your dacha? Then it is better to provide an option with the possibility of cooking. If you plan to use the stove outdoors, appearance does not matter much, but it is advisable to make a beautiful heating source for the house. Depending on their purpose, potbelly stoves can be classified into the following types:

• devices equipped with a cooking surface;
• long-burning furnaces;
• design with increased heat transfer effect.

Often, making a potbelly stove does not require significant financial outlays for the purchase of materials. Craftsmen suggest making a stove from the following available materials:

• metal box;
• gas cylinder;
• milk can or other metal object cylindrical shape;
• suitable sheets of metal.

The standard elements of a potbelly stove include:

• fuel combustion chamber;
• grate;
• ash compartment;
• chimney pipe.

Individual potbelly stove designs may differ from the usual standards, be improved and supplemented with individual elements.

Spent fuel device

Making a potbelly stove for your garage with your own hands using spent fuel for heating is a double benefit. Receiving the desired heat, the owner of the stove simultaneously disposes of waste. A device of this design includes two tanks, a connecting pipe and a chimney. Reservoirs for potbelly stoves can be made cylindrical or rectangular. Any construction is preceded by preparatory stage, including the design of the future furnace.

Tank sizes vary depending on the intended fuel volume. It is necessary to make a connecting tube in compliance with certain proportions: 10 cm - minimum diameter, the length exceeds the diameter by 4 times. It is necessary to make 50 holes along the entire circumference and length of the connecting tube. It is located between two containers. The height of the stove chimney is at least 4 meters.

What else needs to be done for such a potbelly stove? The lower tank is equipped with a lid with two holes for supplying oil and air, and legs are mounted below. After which all parts of the furnace (2 tanks and a connecting tube) are carefully welded.

The principle of operation of a potbelly stove during mining is as follows:

• spent fuel is poured into the cold furnace through the neck in the lower container;
• then kindling material is fed into the same hole;
• During operation, a slight hum is heard - this is a normal process.

If you make containers of sufficient size, the top one can be used to heat food or water.

Important ! The fuel level in the stove should not reach the tank lid; be sure to leave some free space.

Gas cylinder construction

Being the owner of a gas cylinder, making a potbelly stove out of it with your own hands is the most the right decision. Thick walls will allow you to make a mobile and durable structure. It is proposed to make a stove in two options - placing the cylinder horizontally or vertically. Let us consider in detail the second version of the potbelly stove. Manufacturing takes place in several stages:

• in the center of the cylinder the entrance to the combustion chamber is marked;
• stepping back down 10 cm, apply the contour for the blower;
• You can make holes using a grinder;
• a closed line is drawn between the two doors, along which the cylinder is cut into two parts by an autogen;
• a grate is welded to the lower shape of the stove in the cutting area, through which ash from burnt firewood will fall into the ash pit;
• after attaching the grille, the gas cylinder is connected back together by welding;
• in the area of ​​the valve for proper operation the stove needs to make a hole with a diameter of about 20 cm, into which a pipe is installed that performs the function of an exhaust hood;
• All that remains is to make the legs for the potbelly stove, and the main part of the work is completed.

If you consider yourself an aesthete and want to amaze your friends who come to visit for a light with your neatness, you can open the structure with heat-resistant paint.

This type of stove is suitable exclusively for heating purposes. If your tasks include heating or cooking food, then some adjustments will need to be made to the top of the oven. To do this, instead of the cut off top, rods are welded inside to be able to install the dishes. It is necessary to make a hole for the pipe, mandatory for any potbelly stove, on the side at the top of the device. At times when the potbelly stove is used only for heating, the grate for dishes is closed with a lid made from a cut-off part of the cylinder.

Advice ! Don't forget to equip the oven lid comfortable handles for ease of removal when the metal is heated and weld the hole where the valve was located.

Rectangular potbelly stove

For country houses Rectangular is more suitable. For efficient and long-term use, it is very important to make a heating device from metal sheets of the correct thickness. Unnecessarily thin material will quickly burn out and the potbelly stove will fail in as soon as possible, and if you make a stove from too thick sheets, long heating will significantly reduce its efficiency. Optimal thickness material for walls - from 4 mm. It is better to make partitions from metal with a thickness of more than 10 mm. For a rectangular potbelly stove you will also need a grate, a hood pipe and corners for a stand. Correct design will ensure economical fuel consumption and the ability to regulate air flow.

You can make a stove in the same way gas cylinder With vertical arrangement, but it is better to upgrade the device in order to increase efficiency. In this case, in addition to the body, it is necessary to make partitions from thicker metal intended for installation in the upper part of the fuel compartment. A small improvement creates a kind of labyrinth for the smoke, which slows down the cooling process of the potbelly stove. At the top, in addition to the hole for the chimney, it is recommended to make another hole to allow cooking.

Advice ! When welding the side walls of the potbelly stove to the bottom, use a level to ensure strict adherence to the vertical lines.

The internal space of the stove is divided into 3 parts - the ash pan, the firebox and the “labyrinth” for smoke. Between the first two, a grate is installed on which solid fuel is placed. If you want to make it yourself, make sure you have thick sheet steel. Strips with a width of 2.5-3 cm and a length corresponding to the size of the potbelly stove are welded to metal rods with a diameter of 1.5-2 cm at a distance of 5 cm from each other. Experts recommend making a removable grill so it can be cleaned or replaced. For fastening inside the potbelly stove, corners are first welded along the entire length.

The next stage is to make support strips welded to the side walls of the stove and you can proceed to making doors for the firebox and ash pan. Hinged hinges will help secure them to the main structure of the potbelly stove. Finally, you should make a chimney pipe.

Long burning stoves

Firewood in standard devices burns out quickly and requires regular addition. But craftsmen suggest making a long-burning potbelly stove, especially necessary for heating a dacha. Its design is radically different from the types described in the previous sections. For manufacturing, you will need a cylindrical container made of metal of suitable thickness. The process of creating a long-burning potbelly stove includes the following steps:

• the upper part is cut off, in the future it serves as a lid;
• a hole should be made at the top side of the potbelly stove for exhaust hood;
• firewood is laid through top hole, and not through the side doors as in standard ovens;
• then you need to make a metal circle, with a diameter slightly smaller than a potbelly stove, with a hole in the center;
• a pipe is inserted into the prepared opening, exceeding the height of the stove and performing the function of a blower, in order to maintain the combustion process due to the supply of oxygen;
• Finally, it is necessary to make an opening in the lid of the potbelly stove, ensuring a free but tight passage of the blower pipe.

Note! A long-burning potbelly stove is intended exclusively for heating purposes and does not allow organizing the cooking process.

Fuel is initially loaded into the finished device. When the firewood is well lit, a disk with an exhaust pipe is placed on top, then the lid is closed. The operating principle of the stove design is based on an insufficient supply of oxygen, as a result of which the wood does not burn out quickly, but smolders slowly, providing heat for 8 hours.

Manufacturing Features

To increase the efficiency of a potbelly stove, it is advisable to make an exhaust pipe that extends throughout the room as much as possible. The horizontal position of the hood in a certain area will allow the smoke to additionally provide heat rather than immediately escape outside.

Taking care of safety measures, experts recommend making a box around the potbelly stove to prevent the risk of burns. To do this, you will need to install additional plates at a distance of 5-10 cm from the stove. Air gap will not allow significant heating of the box and will provide a comfortable feeling when you are near the potbelly stove. It is better to make such protection for a rectangular oven; with a cylindrical shape, the design is impractical.

Some craftsmen adapt a potbelly stove for two types of fuel. Adding an infrared burner to the design allows you to make a universal stove that runs on wood and gas. Showing their imagination, some create models that serve original decoration cottages or capable of heating water in a tank located next to the stove.

Advantages and disadvantages of a potbelly stove

Having studied the advantages and disadvantages of the design, we can conclude that it is necessary or not to make a potbelly stove with your own hands. The main advantages are as follows:

• the possibility of using inexpensive raw materials: sawdust, firewood, peat or coal are suitable for heating;
• small financial costs to make the device; purchasing a finished stove will cost much more;
• compact design dimensions;
• the ability to operate a potbelly stove without a major chimney;
• easily transported to another place.

Negative aspects include the following:

• mandatory protection on the floor in case of falling embers;
• high-quality thermal insulation of the wall surface located near the stove;
• hot walls are a source of risk for burns;
• fast fuel consumption, heating is carried out only with regular addition.

Like any heating device, a potbelly stove has certain advantages and some disadvantages. Therefore, before you make a comfortable stove with your own hands, think about the design that is most suitable for your purposes, then the result will please you for a long time.
