Garage oven: DIY. Pros and cons of a homemade long-burning wood-burning stove Do-it-yourself garage oven drawings

For some men, the garage is their second home - they spend a lot of time here, fiddling with the car and doing other tasks. And for others, it's a way to make money repairing cars. In any case, the workplace should be comfortable and warm. The worst situation is with heating - here you need some simple and efficient stove for the garage, the operation of which will not lead to high costs.

In this review, we will look at:

Cons of using electric heating;
Available types of fuel;
Schemes of homemade stoves for the garage.

Armed with tools and a welding machine, you can make a great garage oven.

Electric heating

Most often, there is no heating in the garage - here it is not needed, since the car can easily endure any cold. But if people are constantly in the garage and work, you need to create favorable conditions for their long stay. The easiest way to solve the heating problem is with electric heaters. Here are their main advantages:

As a heater for the garage, it is quite possible to use an electric heat gun.

Quick start - just plug the heater into a power outlet, and after a while it will become warm in the garage;
Large selection of models - from heat guns to convectors;
No need to fiddle with fuel - a simple outlet is enough.

There are also certain disadvantages:

High electricity consumption is one thing when heat is needed once a week, and quite another when it is needed every day and for several hours;
Lack of economy - as a rule, garages are not insulated, so the costs will be high;
Low efficiency - electric heaters are good for residential premises, and in the conditions of a garage blown by all the winds, the effect can not be expected.

The most efficient electric garage heater is a powerful fan heater that delivers almost instantaneous heat and impresses with its reliability. Also here you can install infrared heaters that heat not the air, but the surrounding objects. But the operation of all these devices will inevitably lead to increased energy costs. The way out of the situation will be homemade stoves.

Garage stoves and their varieties

Before we tell you how to make a do-it-yourself stove for a town, let's try to consider the main types of stoves and the types of fuel available to us. To heat garages we can use:

Diesel fuel;
The most common firewood;
Coal;
Petrol;
Working off.

A shop diesel oven works without a chimney and takes up little space.

A purchased diesel stove for a garage is an excellent and aesthetic solution. It will allow you to completely warm up the garage, working on a simple diesel fuel. Such a stove quickly ignites and enters the operating mode, does not require a chimney. But it must be remembered that you will be forever haunted by the smell of diesel fuel, which is simply impossible to get rid of. In addition, you will need to buy diesel fuel somewhere, spending large sums on heating.

There is practically no high-quality diesel fuel, which will give a minimum of an unpleasant odor, on sale.

With the help of a gasoline stove for the garage, the design of which we will describe in our review, you can quickly warm up the working room. The main thing is to get cheap gasoline from somewhere. A gasoline-powered barrel garage oven will delight you with its ease of manufacture. And such a unit can be used to heat any other premises, for example, country houses.

The main feature of our stove will be the absence of a strong unpleasant odor during its operation.

If you have a solid fuel stove, you will have to find a place to store firewood.

Solid fuel stoves on wood and coal please with simplicity and affordability. Fuel for them is cheap, and in some cases free. A wood-burning garage stove has a simple design, does not give off an unpleasant smell of petroleum products, and can run on various types of solid fuels. Only now the owner of the garage will have to constantly remove the ashes from it, but it can be used as fertilizer in your garden or vegetable garden.

An oil stove (aka a working out stove) will please you with the simplicity of its manufacture. A do-it-yourself device installed in a garage will provide people with warmth. And if your activity is connected with frequent oil changes, then you will have at your disposal an inexhaustible and free source of fuel. Let's see how to make a garage oven and what you need for this.

Gasoline stove from a barrel or pipe

Considering the most popular garage heaters, one cannot pass by one simple but very effective stove. It is not gas and not wood - it is on gasoline. Its dimensions vary depending on the size of the workpiece for the body. You can put it anywhere in the garage, for example, at the side wall or in the corner. For this we need:

There is nothing complicated in the design of a gasoline stove.

A metal barrel or a piece of pipe with a diameter of 300-400 mm;
Thick metal wire;
Blowtorch;
Large river stones;
Curved pipe for a chimney with a diameter of 100 mm.

Our task is to prepare the combustion chamber. To do this, we make a small hole in the lower part of the barrel (in the side wall, at the very bottom), into which we will insert a blowtorch burner. If you are using a pipe, not a barrel, weld the bottom to it, then make a hole for the lamp - it would be nice if this hole could be covered with something.

At the next stage, we take a powerful metal wire, bend it so that it forms an elastic stand for stones - the wire goes to the bottom of our garage stove. We lay rounded stones on it (there are a lot of them in mountain rivers), to the very top (the wire must withstand their weight). Next, we attach a chimney to our stove.

Before you start stuffing the garage stove with wood, make sure to place it on bricks or any other non-combustible base.

Now you can start the test run of our garage stove. Pour gasoline into the blowtorch, wait for it to enter the operating mode, carefully insert the lamp into the hole prepared in advance for it, wait until the stones warm up. After burning for only 1 hour, the stove will give off heat for another 3-4 hours. If you can make a chimney with a valve, the heat will remain even longer.

At the stage of burning a blowtorch, it is necessary to ensure the ventilation of the garage, since the stove takes air directly from the room (like any other stove from our review).

Making a potbelly stove

Let's see how to make a potbelly stove in the garage. Potbelly stoves are distinguished by their extremely simple device. Here are their benefits:

Omnivorous - these stoves can run on any type of fuel, both wood and coal;
The potbelly stove can be used for cooking - teapots, pots, pans and other utensils are placed on its upper surface;
Do-it-yourself potbelly stove for a garage will please you with ease of manufacture - sheet metal and a chimney pipe are needed for the stove;
A home-made potbelly stove does not require some kind of tricky ignition - just put firewood in it and set it on fire. Then you can put coal into it.

Do-it-yourself potbelly stove in the garage is a great way out when you have the opportunity to buy firewood. And by typing them in the nearest forest, you will receive a source of free heat. Also, any wood waste, eurofirewood and even pellets are used to fire the stove.

The drawings of the potbelly stove are extremely simple - its device can even be described “on the fingers”. It is a metal box with two doors on the front panel. Through the top door, the largest, firewood is loaded. And through the bottom, combustion products are removed. At the same time, the lower door plays the role of a blower. If it gets hot in the garage, cover the stove blower, and after a while the temperature will drop.

When making a potbelly stove with your own hands, pay attention to the published drawing. You need to weld a metal box with a height and length of 450 mm, a width of 250 mm. In the inner part, at a height of 80 mm, we weld a grate (we can fit a sheet of thick metal with cut holes under it). We also weld chimneys inside to improve traction. In the upper back part, we weld a piece of pipe with a diameter of 100 mm under the chimney.

The stove for a wood-burning garage, she is a potbelly stove, is ready - you can start testing. To do this, stock up on firewood. Installation of the stove in the garage is carried out in any convenient corner. We upholster the walls of the corner with galvanized steel so that the heat does not go into the walls, but is reflected into the garage. Next, we proceed to laying firewood and lighting it up - in much the same way as we kindle a barbecue. With the help of the ash pan door, you can adjust the draft.

When assembling the stove with your own hands, pay attention to the thickness of the metal - it should be at least 5 mm, otherwise the stove will easily burn out and lose efficiency.

brick stove

To create a brick oven, you need to have certain skills.

A potbelly stove in the garage is good because this stove is extremely simple. A few pieces of metal, a little fuss with the welding machine and doors, a piece of metal pipe - and the heating unit is ready. The potbelly stove is not the most economical, but it is easy to operate - you just need to throw firewood in time. A brick oven for a garage is built in a similar way, but it has several disadvantages:

For a good stove you need refractory bricks;
The stove for the garage turns out to be too cumbersome.

However, you can always build it in the likeness of a potbelly stove, but instead of metal walls, ordinary brick is used here.

A metal oven can always be turned over, cleaned or moved to another location. You can’t just clean a brick oven in a garage, and you can’t transfer it to a neighboring corner either - this is a model for stationary use.

Long burning wood stove

Let's see how to make a stove in a garage from a pipe or from a barrel - it will be a stove with the unusual name Bubafonya. When making such units on long-burning wood with your own hands, you don’t have to bother with exact dimensions. This stove is as simple as three pennies, but it has an important advantage - one bookmark of firewood is enough for the whole day. And it is the best suited for heating non-residential premises.

When making a wood-burning stove with your own hands, you need to take care of the selection of suitable materials. We will try to make a stove out of two barrels. We will need the first barrel completely, and the second will require only one lid. Here is a step-by-step instruction for making a garage heating stove:

A drawing of a homemade long-burning wood-burning stove.

We take a barrel and cut off the top of it (leave 2-3 cm at the cut off upper part of the side) - this will be our combustion chamber into which firewood is loaded;
We bend the sides of the barrel inward, and on the lid we perform the reverse operation - as a result, the lid should completely cover the barrel;
We make a press and an air duct - for this we need a cover from the second barrel, we make a hole to it and weld a long pipe, which should be higher than the barrel. On the reverse side, we weld pieces of the channel. We cut the edges of the lid so that it freely enters the barrel (the gap between the lid and the walls is about 10 mm). As a result, we should get a kind of piston. Air is taken through the welded pipe;
We continue to make a furnace for heating the garage - we take a cover for our combustion chamber, cut a hole in it for an air pipe;
In the upper side of the barrel we make a hole with a diameter of 100 mm and weld a piece of pipe - this will be a chimney outlet.

Now our long-burning garage oven needs to be put together and tested at the same time. We install the stove on a non-combustible base, load firewood into it (we advise you to throw any small things on the very top), connect the chimney. Next, we wet a piece of rag in kerosene, throw it on wood, and wait for a steady burning. After that, we put our piston inside, put on the lid and wait until our stove flares up to its fullest.

To make a wood-burning garage oven, you can also choose a piece of a suitable pipe - you can buy it at a metal depot. The amount of loaded fuel is determined experimentally. Please note that the wood in this stove burns from top to bottom, and not in the more usual direction.

Stove for garage working out

Let's see how to weld a stove in a garage that will work on working out - it will come in handy for those who repair cars and often change oil (for one warm season, you can collect working out for the whole winter). Our stove will consist of three parts:

You can get detailed information about the dimensions of individual elements from the drawing.

Fuel tank - its diameter is 352 mm. We weld the legs to it, in the middle we make a hole with a diameter of 100 mm. Nearby we make another 100 mm hole, with a lid - here we will fill in fuel for heating our garage;
Combustion chamber - it is a vertical metal pipe with a diameter of 100 mm, in which 48 holes are drilled in 6 rows;
Afterburner - all unburned gaseous residues are burned here. Its diameter is 352 mm, it has a hole for the combustion chamber and a hole for the chimney (the same 100 mm). A partition is welded inside the chamber.

After the garage stove is assembled, you can start testing. We pour the mining inside, pour a little kerosene on top (in no case, not any other liquid, only kerosene!), set it on fire, wait until the stove warms up. As soon as a steadily burning, literally buzzing flame appears in the combustion chamber, the experiment can be considered a success. Please note that the recommended chimney height for this stove is 4-5 meters.

When making a garage oven with your own hands and choosing a suitable drawing, you should pay attention to the choice of fuel and start from this. If you have a lot of mining, the choice is obvious - we choose the latest stove from our review. If you have a large amount of firewood (including free ones), you can pay attention to alternative projects. And remember that the dimensions of the furnaces in the drawings can vary widely.

A garage is more than just a place to store a car. Many people spend much more free time in it, and it can be not only hot summers, but also cold winters. Of course, it does not make sense to equip a full-fledged heating in such a room, but a useful and practical homemade product will come in handy.

Primary requirements

In a cold autumn or frosty winter, being in a garage without heating is not a pleasant occupation. A good rest or work in such conditions is simply not achieved. That is why such areas simply need a small potbelly stove, which can be made by hand. Potbelly stoves with a heat exchanger are found in many sheds and garages.

The prevalence of such units is due to the simplicity of their manufacture. It does not take much time and expensive materials.

As a rule, such designs need only some modifications, since the body itself, and often the bottom, is already in such an item. Many craftsmen cook garage ovens from sheet materials. However, only those users who know how to work with welding can master such types of furnaces.

Much less often in garage buildings there are home-made stoves made of bricks, since such units have more impressive dimensions, and at the same time they heat up to a lesser extent. For a garage, such a system is poorly suited.

Most often in garages there are small stoves powered by firewood.. In such units, as a rule, absolutely everything that can burn is laid. Unpretentiousness in the choice of fuel and fast heating are the main advantages of such a furnace. However, when choosing a suitable unit, one should take into account not only its “omnivorousness”.

A suitable design for heating a garage area should be selected in accordance with the following parameters:

the area of the garage itself;
terms of use of heating;
the maximum budget that can be spent.

If the garage is an extension to the house, then it is better to put the device with an electric or gas connection.

If the building is separate from the dwelling, then a safe autonomous structure should be created. It is worth remembering that, first of all, a potbelly stove for a garage must be safe, otherwise serious problems with bad consequences may arise.

The oven must have the following important parameters:

the cross section of the exhaust valve must be at least 10 cm;
weight should not exceed 35 kg;
furnace dimensions - 70x50x35 cm;
volume should not be more than 12 liters.

Kinds

Many users choose homemade stoves to insulate the garage. A suitable option can be made for any conditions and layouts. It is worth considering in detail which varieties of garage bourgeois are in demand today and are most common.

oily

Oil ovens are common. Such models most often have the following characteristic features:

they are compact;
differ in a simple design;
quickly warm up;
this stove is easy to use;
in a garage with an oil oven, the optimum temperature will be maintained for a long time;
such units are environmentally friendly, because they do not harm the environment;
fuel for these furnaces can be safely called affordable, since it can be found, for example, at service stations (some companies provide a service for the removal of such fuel);
in oil models there are no droppers, nozzles and other similar parts, so the process of assembling them is considered simple and fast;
oil ovens don't get dirty that often.

brick

As a reliable stationary structure, a brick oven is ideal. The smallest units are considered to be units with dimensional parameters of 2x3 m.

Brick stoves are good for their reliability and durability. However, experts say that you can make them yourself only if you have experience in laying bricks. Otherwise, the unit may turn out to be crooked and less reliable. It is better to hire professionals to perform such work.

Neat brick garage ovens are very popular. Such units are diesel and run on diesel fuel, which is in the public domain.

metal

No less common and in demand are metal garage stoves. Such units have a number of positive characteristics that make them popular among modern owners of garage buildings.

These models are characterized by a high degree of heating, but at the same time they are small in size, so you do not need to allocate a lot of space for their placement in the garage.
Metal furnaces are considered "omnivores". They can run on a variety of solid fuel sources.
The weight of the units is also small, so it is easy and convenient to work with them. In addition, because of this, it is not necessary to build a foundation under them.
Metal stoves are often used to heat food or water.
As a rule, the designs of metal stoves are simple. It is quite possible to make such units with your own hands, having experience in welding.

As mentioned above, these types of stoves can be powered by any solid fuel source. Wood-burning models are considered one of the most common options.

They consist of the following components:

furnaces- the size of firewood and their allowable number depend on its size;
grate- these parts are a grate on which the fuel itself is placed on top, they are designed to form thrust;
ash pan- this element is a compartment into which ash from burned-out fuel enters;
chimney- in this case, this component is a pipe with a diameter of 100 mm or more, which serves to remove flue gases.

The main disadvantage of wood-burning metal stoves is that the fuel burns out in them in a short time, which is why a large part of the heat energy leaves the room in alliance with smoke.

To improve the heat transfer characteristics of an iron furnace, it is recommended to initially make it a two-way furnace.

In such a unit with high efficiency, hot gas passes through special channels located in the inner part of the housing. Thus, the room becomes warm and comfortable.

Missile

Another name for such a furnace is jet. Such models began to be so called because of the jet of flame escaping from a pipe located on top of the passage structures. In addition, the rocket furnace makes a peculiar sound, similar to the roar of an engine.

A simple and uncomplicated jet furnace consists of two pipes. One of them is in a horizontal position, and the second is directed upwards. For the manufacture of such a design, it is permissible to use one curved pipe. The fuel in such a furnace is placed directly into the pipe. In this case, the combustible gas will rush upward, moving along a vertical plane.

If you decide to install a similar unit in the garage, then you should know some of the features that it has, namely:

the rocket stove can be used both as a heating and as a cooking structure;
often reliable and strong “rockets” (combined) are complemented by cozy beds, similar to those found in Russian stoves;
one fuel bookmark in such a furnace can work for about 6–7 hours. At the same time, it retains heat for 12 hours, especially if it is treated with adobe plaster;
Initially, these types of stoves were used exclusively in the field. Currently, portable "jet structures" are among the most popular, however, there are also stationary installations that work in exactly the same way as clay or brick models.

These types of ovens have the following advantages:

these designs are simple. They can be easily made by hand. In addition, you do not need to buy expensive materials for this;
having a rocket furnace, you can use any kind of fuel. In such a unit, even low-quality fuel will burn;
such models are energy independent;
These furnaces are characterized by low fuel consumption.

However, these types of furnaces have some disadvantages, which include:

manual control, due to which such a unit must be constantly monitored, regulating the combustion process;
some elements of such a furnace can become too hot, especially if they are made of metal - you can easily get burned on a similar design;
such stoves can not be located in all rooms, for example, they are not suitable for a bath at all.

Steam

If there is a desire to place a budget stove in the garage, then it is worth considering the option of assembling a steam structure. Such ovens perfectly maintain the optimum temperature in the garage. In addition, they can operate not only on electricity, but also on any other type of fuel.

Such models consist of the following elements:

steam boiler;
steam turbine;
reducing and cooling plant.

Fuel selection

Furnaces for garage buildings differ not only in their designs, but also in the fuel from which they work.

Gas

Gas ovens in garages are connected in two ways, namely:

using a gas line;
using liquefied gas.

The first method is rarely used, since most garages are not connected to gas networks. More common are furnaces powered by liquefied gas in a cylinder. It is connected to the unit using a special hose. During the operation of the stove, the processed gas is selected outside through the chimney. Such structures operate without electricity.

In addition, they are mobile. In some instances, there are sensors with which the gas is blocked if it leaks. The use of such a unit is preferred, as it is characterized by the best safety in terms of operation.

Electrical

Such ovens are very popular and are quite common. Electric furnaces include oil structures, heat guns, and electric convectors. As a rule, models powered by electricity are small in size. They do not need a chimney and ventilation. Such units do not burn oxygen in the room.

The disadvantage of electrical products is that they consume a lot of electricity. In addition, they make a lot of unpleasant noise during operation.

solid fuel

No less popular are solid fuel stoves. These options include wood stoves, good old potbelly stoves and stationary structures made of brick. The principle of operation of these models is quite simple - firewood, peat and coal are burned in a special combustion chamber, after which the already used materials come out in the form of smoke through a pipe.

The disadvantage of such stoves is that they need to allocate a separate space in the garage for their fuel, which can be a problem in a small area.

Diesel

Solar furnaces consist of two main sections, such as:

furnaces;
solar storage tank.

In this case, diesel fuel comes from the storage tank and passes through the nozzle.

Such furnaces are equipped with a fan designed to disperse the air necessary for the active combustion process. Products on diesel fuel quickly warm up the territory entrusted to them.

Spent fuel

A good solution for a garage is an oil-fired oven. Such a unit is able to maintain heat in the room for a long time.

Many consumers prefer this particular model, since it does not need to be purchased with expensive fuel. All that is needed for such a unit is recycled engine oil, and the use of fuel oil, kerosene, heating oil or solar oil is also acceptable. Such a model can be made by hand.

On sawdust

Sawdust units belong to the category of long-burning furnaces. In such models, sawdust not only burns, but gradually smolders. At this point, a sufficient amount of heat is released, which is quite enough for a garage room.

In order for the sawdust to burn as long as possible and give off a lot of heat, you need to tamp them well.

The assembly of such an oven is simple and fast.

Potbelly stove

One of the most popular today are economical wood-fired stoves. Their feature is the presence of two chimneys located inside the furnace itself. These details provide the best heat dissipation of the structure.

These ovens are made from the following materials:

sheet metal with a thickness of at least 4 mm (preferably 5 mm). From this material it is necessary to weld the body, as well as doors and smoke turns;
a sheet of 6 mm for the vault of the firebox;
a small piece of pipe with a diameter of 100 mm on the chimney pipe;
reinforcement of a periodic profile with a diameter of 16–18 mm (needed to create a grate);
corner No. 4 and rolled metal for the manufacture of legs;
finished door handles.

When using these materials, you will definitely get an ergonomic and inexpensive oven that will last a very long time.

Stove "dropper"

Such a stove is ideal for a small garage that does not have heating and electricity. Such an effective design can be assembled with your own hands.

It has the following advantages:

saves fuel;
easily moved to a new place;
easy to use;
also used for cooking.

In order to perform some work in the garage or in the country during the cold season, you need to organize the simplest heating. Knowing how much electricity costs today, most garage craftsmen prefer to use factory and home-made heaters that operate on wood or oil mining. The purpose of our article is to provide drawings and describe in detail how to make a potbelly stove with your own hands for use in a garage or a small country house.

We select the design of the stove

Since there are enough drawings of ordinary potbelly stoves on the Internet, we will offer a choice of 4 original designs, one of which will certainly suit your conditions:

Two-way wood and charcoal stove, welded from sheet metal.
Vertical heater from a gas cylinder with an air or water circuit.
Long-burning pyrolysis stove from a cylinder or pipe installed horizontally.
Dropper for the development of automotive and other oils.

Unit with two chimneys

Note. The heating furnace can also be built from ceramic bricks, which is described in this topic. Such a heat source will fit well into the interior of the cottage, but is inconvenient for a garage due to the size of the brick building, long warm-up and lack of mobility.

Wood burning heater with air chamber at the top

If you spend a little time in the garage (1-3 hours a day), then you will need a quick heating of the room, and it will be provided by a vertical wood-burning stove with an air heat exchanger (option No. 2), shown in the photo. Thanks to the fan that drives air through the upper chamber, it acts like a heat gun.
The same second option will fit for large boxes (standard garage dimensions are 6 x 3 m). Then the air chamber turns into a water circuit connected to the heating registers.
For permanent heating of a standard garage, option No. 1 is suitable - an efficient two-way wood-burning stove, or No. 3 - a long-burning unit. The choice depends on the material you have: the first is made from a propane tank, the second is made from 4 mm thick sheet iron.
For those who plan to burn used oils for heating, it is recommended to weld a drip-type stove from a round pipe (option No. 4). If you wish and skill, you can upgrade it - convert it into a boiler by making a water jacket.

Double chamber pyrolysis oven

Reference. Of the popular garage homemade products, it is worth mentioning 2 more designs: the famous stove - Bubafonya upper burning potbelly stove and a small heater made of rims. The manufacture of the first is described in detail, the second is shown in the video:

Assembling an efficient potbelly stove

It is well known that ordinary iron stoves are characterized by low efficiency (about 45%), since a significant part of the heat goes into the chimney along with the flue gases. Our design implements a modern technical solution used in solid fuel boilers - the installation of two partitions on the path of combustion products. Going around them, the gases transfer thermal energy to the walls, which makes the efficiency higher (55-60%), and the potbelly stove is more economical. The principle of operation of the unit reflects the drawing - diagram:

For manufacturing, you will need a sheet of low-carbon steel 4 mm thick, a piece of pipe Ø100 mm and rolled metal for the legs and grate. Now about how to make an economical potbelly stove:

Cut metal blanks according to the drawing and make openings for the doors of the firebox and ash pan.
Weld a grate from corners or fittings.
From the cut parts, make doors with locks.
Assemble the unit on tacks, and then weld the seams solid. Install the flue pipe and legs.

Advice. The lower partition, strongly heated by the flame, is best made of thicker iron - 5 or 6 mm.

For better heat transfer, craftsmen practice welding additional outer ribs to the body, as is done in the photo.

How to weld a vertical furnace from a cylinder

This stove-potbelly stove differs from similar units in the presence of an air chamber arranged in the upper part and completely isolated from the firebox by a steel partition. Inside it, heat exchange fins are installed through which the heated air is blown by a fan. For supplying cold and ejecting hot streams, branch pipes with a diameter of 40-50 mm are built into the cover, which is shown in the drawing.

Note. The organization of the air heating chamber in the upper zone of the firebox allows you to take the heat of the combustion products passing by it into the chimney. Since the flame covers the entire portion of firewood in a vertical oven, the air flow in a separate compartment is intensely heated, due to which the temperature in the garage rises quickly.

The first operation is the correct disassembly of a 50-liter propane tank. To displace the remaining liquefied gas, it is necessary to unscrew the valve and fill the tank to the top with water. After the grinder, you need to cut off the cover (the cut line is the factory seam) and proceed in this order:

In the side wall of the cylinder, make rectangular openings for the ash and loading doors and frame them with a 3 mm thick steel strip, as shown in the drawing. Cut a hole Ø100 mm for the chimney.
Make removable grates and install them inside the body on the welded corners.
Make the doors of the ash and fuel chambers, attach handles and hinges to them, and then install them in the framed openings.
Cut out a circle Ø30 cm from metal 4 mm thick - this will be the bottom of the chamber. Weld ribs from rolled metal waste to one of its surfaces, and then hermetically dock it with the firebox for welding.
Make 2 holes in the cut cover and weld the pipes for connecting the air ducts. When ready, install the cover in its original place (but now - above the heat exchanger) and carefully go through the joint by welding.

A vertical potbelly stove in a garage is capable of burning wood of various qualities and humidity, including sawdust, as well as supplying heated air to any point in the room, which is important for greenhouses. In addition, it can provide heat to radiators and registers if they are connected to the nozzles in the upper chamber cover and the system is filled with coolant.

Attention! To avoid boiling water and breaking pipes, you need to create its constant forced circulation from the pump and install an open expansion tank. Use antifreeze as a coolant, because the garage is not heated around the clock.

Production of a horizontal heater

If you lay a standard propane cylinder horizontally and arrange a door at the end, you will get a fairly roomy firebox, which will include meter-long logs. For better heat transfer and afterburning of the resulting pyrolysis gases, it is necessary to make a secondary chamber with partitions, as shown in the drawing.

The afterburning of combustible gases in this potbelly stove is combined with the removal of heat from the products of combustion, enveloping hemispherical partitions (cut out from the cylinder body). Well, an indispensable attribute of intense heat transfer - external ribs made of steel strips - are required. Practice shows that such a stove heats a garage up to 50 m² in medium burning mode, as described in the next video:

In manufacturing, the heating unit is simple: doors are installed in the front part, and a hole is cut in the back, where the secondary chamber is welded from a pipe or a second cylinder. In order not to take away the useful volume of the firebox, the ash pan is made hinged. If necessary, a hob is arranged on top of the horizontal part.

We make a potbelly stove at work

Diesel fuel and used engine oil are very high-calorie fuels. If you get it inexpensively, then it makes no sense to mess with firewood and coal, it’s easier to make a reliable furnace - a dropper. Its principle of operation is to burn mining, dripping into a red-hot bowl. Moreover, along the way, liquid fuel has time to warm up, as it passes through the oil pipeline built into the pipe - the afterburner. The drip-type potbelly stove device is shown in detail in the drawing.

For efficient combustion of oil, air is forced into the stove using a fan, and mining flows naturally from a tank suspended from the wall next to the heater. Another option is the forced supply of fuel by pressurizing the fuel tank (for example, with a hand pump).

Both a pipe Ø219 mm and a propane cylinder with a diameter of 30 cm can act as a furnace body. Making an oil potbelly stove with your own hands is a simple task, the main thing is to make holes and slots in the afterburner correctly and lay the fuel pipe to the bowl installed at the bottom. A complete assembly guide is provided in our other article. You can get a closer look at the operation of the heater from the video:

Conclusion

It must be understood that the designs of wood-burning and oil stoves for the garage shown above can be changed and refined by you during operation. That's the beauty of homemade stoves - they are improved according to your desire. Example: garage craftsmen often make an external water circuit based on a samovar heat exchanger built into the vertical section of the chimney. This makes it possible to use water heating without interfering with the design and altering the furnace itself.

Wood-burning solid fuel stoves have one serious drawback: it is very difficult to achieve automation of the combustion process, and for some designs it is impossible. Periodically, you have to be distracted from business and throw firewood, which burns out in about an hour. To extend the operation time of the furnace on one load, the furnaces are equipped with a long burning mode.

Wood combustion is a complex physical and chemical process that occurs in several stages. During ignition, while the temperature in the stove is low, the wood heats up and darkens. At temperatures above 200 degrees, pyrolysis begins - decomposition under the influence of temperature into solid residues and pyrolysis gases. These gases are themselves flammable because they contain hydrogen, carbon monoxide, organic vapors and carbon in the form of soot. It is the combustion of pyrolysis gases that gives a bright flame with a high temperature.

In a conventional furnace, complete burnout of pyrolysis gases does not occur due to a lack of oxygen. In long-burning furnaces, for the afterburning of pyrolysis gases, a separate chamber or compartment of the furnace is intended, where they are enriched with air oxygen. Thanks to this, a more complete combustion of fuel occurs, less soot and other harmful substances are released into the air, and the efficiency of the furnace increases.

To avoid excessive temperature in the firewood pre-burning chamber, air access to it is limited. Firewood begins to smolder, releasing a large amount of pyrolysis gas. Due to the slow smoldering of firewood, the operating time of the stove at one load is significantly increased, in some cases reaching 6-8 hours. This phenomenon is called the "long burning regime".

Advantages and disadvantages of long burning stoves

Like any other unit, such furnaces have their pros and cons.

The undeniable advantages include:

economical consumption of firewood;
high efficiency, up to 85-90%;
versatility in the choice of fuel, firewood, and waste from woodworking enterprises, and sawdust, and pellets are suitable;
small sizes;
ease of control - using a damper for air supply;
simplicity of design, thanks to which a long-burning stove is easy to make with your own hands.

Not without a long-burning stove and disadvantages:

during combustion, condensate is released, on which soot is actively deposited in the chimney, therefore, special requirements are imposed on the device of the chimney - it should not have corners, bends, its design should be as accessible as possible for cleaning;
in order to switch to the long burning mode, the stove must first be heated in the normal mode in order to warm up the stove itself and the chimney, otherwise the burning process will stop.

All the described features of long-burning stoves are relevant both for industrial heating units and for do-it-yourself stoves.

You can increase efficiency by adding a stove, as shown in the video.

The design of long-burning furnaces

Long-burning furnaces have design features. They consist of two chambers or combustion zones, in one of which pyrolysis of firewood takes place, and in the other - afterburning of wood gases. The location of the cameras relative to each other can be different.

In some models, fuel is loaded from above, as a result of primary smoldering, firewood is compacted and settled, and gases enter the afterburner chamber, which can be located both below and through a partition on the side of the first chamber. Such stoves are often equipped with blowers to direct the draft into the desired channel.

In other models, the pre-combustion chamber is located at the bottom, and the pyrolysis gases rise into the upper chamber without forced draft. For such stoves, a fan is not needed, but the volume of the loading chamber is usually smaller.

To regulate the intensity of combustion, an air supply channel with a damper is made. It can also have a different shape and depends on the type of stove. To compact the fuel and more intense smoldering, some stoves are equipped with a load that lowers as the firewood burns out. Usually they have such a design.

Application of pyrolysis ovens

Long-burning stoves on wood, pellets or sawdust are often used to heat utility rooms and workshops, garages, greenhouses. They can also be used for heating a house, but it is necessary to ensure the tightness of the furnace, since carbon monoxide may be released.

In the case of using a pyrolysis stove for heating a garden or residential building, it is better to equip it with a water circuit connected to heating radiators, and install the heating unit itself in a boiler room.

Materials for the manufacture of a long-burning stove

Long-burning furnaces can be made by hand from sheet metal or various metal structures. Examples and drawings of such stoves are given below.

barrel stove

A do-it-yourself heater designed for heating utility rooms is made of a two-hundred-liter metal barrel. The stove runs on sawdust, shavings and other woodworking waste. A small barrel for loading fuel is installed on a stand inside a large barrel. Under it is an ash pan - a drawer made of sheet metal.

The stove itself is placed on a stand, the role of which is played by a car disk. A smoke branch pipe is made from scraps of a pipe with a diameter of 100-150 mm. The barrel is equipped with a sheet metal lid with a handle and an air inlet.

Inside a small barrel, a log sharpened into a cone is installed, it is indicated in the drawing. Sawdust is piled around it. After tamping, the log is taken out and the sawdust is set on fire. In the process of smoldering, gas is released into the space of a large barrel, where it is afterburned.

Furnace with a water circuit from a metal pipe

A home-made long-burning stove made of a metal pipe that can run on wood or sawdust is equipped with a water circuit. Loading is made from below, to intensify combustion, an air distributor is installed inside the furnace, pressing smoldering firewood.

A telescopic hollow pipe is installed in the center of the disk, through which air enters directly into the combustion chamber, where, thanks to the ribs welded onto the disk, it evenly distributes it over the entire surface of the firewood. It goes down on its own as the fuel burns out. You can lift it before loading with a cable.

The loading door is located in the center of the oven. Below is a cleaning door and an ash pan. At the top is a chimney. The stove is equipped with a water circuit with nozzles for water inlet and outlet. Such a stove with a water circuit can quite effectively heat small houses and other premises, and you can make it from improvised materials with your own hands.

Waste Gas Cylinder Furnace

A stove from a gas cylinder can be made without extra costs and finding the right material. The dimensions of a 50-liter cylinder are perfect for making such a stove, and the wall thickness and tightness make it safe to use.

The design of the furnace as a whole does not differ from the previous model, this can be seen in the drawing. A cut-off propane tank is used as the body. Do-it-yourself sheet metal is made with a suitable size cover with a hole for the air distributor pipe.
Fuel is loaded through the top, filling the volume of the cylinder almost to the chimney. Such a stove works on sawdust and other waste, as well as on small firewood. The fuel is carefully tamped, ignited with wood chips or an ignition agent and an air distributor is installed, after which it is covered with a lid.

The efficiency of such a stove is quite high, and thanks to the hermetic case, it can be used to heat rooms where people stay for a long time. If desired, it can be equipped with a water circuit by passing the chimney through the boiler.

Furnace "Bubafonya" from a gas cylinder

Making a do-it-yourself long-burning furnace from a fifty-liter gas cylinder is shown in the video.

The design of the stove is as simple as possible, it consists of only a few parts: a body, a cover, an air distributor and a chimney. For stability, the oven can be placed on legs from the corner. To remove ash from below, you can make an ash pan with a door.

Sequencing

The remaining gas is released from the gas cylinder and washed several times with water.
Cut off the top of the balloon. You can make a furnace cover out of it by making a hole with a diameter of 65 mm in the center. The edges of the lid and body of the furnace are ground so that the lid fits tightly onto the body.
In the upper part of the cylinder, a hole with a diameter of 100 mm is made for the chimney and a pipe section 30-40 cm long is welded horizontally.
At the bottom of the cylinder, an ash pan cleaning door is made. To do this, cut out a rectangular section of the cylinder body, grind the sections, weld the hinges and install the door on the resulting hole. The door is equipped with a latch.
The balloon is placed on legs for stability. They can be made from a corner, pipe scraps or a rim.
For ease of carrying, bar handles are welded on the sides.
The critical part of the oven is the air distributor. It must be heavy enough to effectively clamp down on sawdust and wood chips, withstand the heat of the kiln, and have divergent blades. They can be made from scraps of a corner. The distributor itself is made of thick-walled steel - at least 6 mm. Cut out a circle with a diameter of 20-40 mm less than the inner diameter of the furnace with a hole in the center. A pipe with a diameter of 60 mm and a height greater than the height of the stove is installed in the hole. Through it, air will flow to the combustion chamber. The blades are welded at the bottom of the disc.
The body of the stove can be painted with paint based on organosilicon compounds with your own hands, having previously removed scale, rust and dirt from its surface. Any other paint will quickly burn out, as the stove heats up to high temperatures during operation.

The temperature of the walls of the stove from a gas cylinder can heat up to 350 degrees during the fire! Care must be taken to avoid serious burns!

Homemade sawdust stove "Bubafonya" can be equipped with a water circuit. In this case, it is installed in a permanent place. Usually, this stove is used as a mobile one: it can be put in a greenhouse for the time of freezing, it can be used to heat a workshop or a barn in winter, or it can be used to heat a garage. Subject to fire safety requirements, Bubafonya is safe and effective.

For a comfortable stay of a person in a room such as a small garage, it is required to maintain a comfortable air temperature in it. This will help to make a stove that you can make yourself. How to weld the stove in the garage yourself and what is required for this will be described in this article.

Collapse

Materials for the manufacture of homemade garage ovens can be:

Metal barrels;
Disks from trucks;
Used gas cylinders;
Pieces of sheet steel;
Pipe sections.

What to make a garage oven from, choose only for the car owner, based on the availability of the material and type of fuel. Home-made stoves can work both on wood and on coal, used engine oil or diesel fuel. It should be remembered that self-production of gas furnaces is not recommended and life-threatening.

Making a garage oven from a pipe

Below is a photo of a do-it-yourself stove in a garage from a pipe:

materials

To make a garage stove from a pipe, you will need the following materials:

The main pipe, preferably with a diameter of 500 millimeters or more, 1.5 - 2 meters long;
A pipe for attaching a chimney, 40 centimeters long and 150 - 200 millimeters in diameter;
Metal sheet 4 - 5 mm thick;
A piece of metal 3 centimeters wide, for the side on the furnace lid;
Channel or corners with a face of 50 - 70 millimeters;
Grate for the grate, along the length of the pipe and a width equal to its diameter;
Metal handles (for body and lid) in the amount of 4 pieces.

Tools

Do-it-yourself oven from a 500 mm garage pipe for a garage can be assembled using tools and fixtures such as:

Electric welding machine;
A set of files;
Hacksaw for metal;
Hammer or sledgehammer;
Building level;
Roulette;
Marking tool - ruler, core, marker.

Do not forget about personal protective equipment: a welder's mask, leggings, gloves, a protective suit with flame retardant impregnation.

Drawing

Do-it-yourself diagram and drawing of a furnace in a garage from a 500 mm pipe is shown in the photo:

The order of assembly of the furnace unit

After finishing work, you need to install the oven on a solid base, as an option, on four bricks. Next, you should connect the chimney to the pipe and make a trial kindling of the stove. This is necessary in order to make sure that the welds are sealed.

It is worth remembering about safety, any process of burning wood or coal is accompanied by the release of a life-threatening, insidious and imperceptible gas - carbon monoxide, which has no smell. Therefore, the issues of smoke removal should be treated with great responsibility.

Making a garage oven from old rims

This method is quite popular with motorists, since old unnecessary wheel rims can be found at any car depot or in a garage cooperative. The undoubted advantage of such structures is the large thickness of the metal of car rims, such a design will not burn through for a long time and will serve its owner for many years.

Below is a photo of a do-it-yourself oven made of rims in a garage:

materials

Only disks of solid diameters, for example, from trucks or special equipment with large wheels - tractors, graders, etc., will go into work. How to weld a garage oven from rims and what materials are needed for this:

Two or three car rims. It is better to use stamped ones, as they are made of thicker metal. But alloy wheels with an admixture of aluminum cannot be used, such a furnace will simply melt during operation.
Corners or channel for legs, 4 or 6 pieces of 25 - 30 centimeters.
Door hinges.
Bolts and nuts.
Sheets of metal 4 - 5 mm thick.
Two circles, with a diameter of the edge of the disc rim (for the bottom and roof).
A branch pipe with a diameter of 125 - 150 millimeters for the chimney outlet.
Round grate.

Tools

Tools for creating a stove from discs are used almost the same as when creating a stove from a pipe, but there are differences. List of what you need for assembly:

Electric welding machine;
Gas cutter (if available), but you can do without it;
Angle grinder or grinder;
Electric drill;
Hand saw for metal;
Hammer or sledgehammer;
A set of files;
Pliers or pliers;
Marking tool - ruler, core, marker;
Building level;
Roulette;
Paint brush.

Manufacturing schemes

Do-it-yourself oven in the garage made of iron, made of rims, and various options for its design are shown in the diagram:

Assembly order

A vertical stove made of old wheel disks can work on the principle of a buleryan stove or a stove for long-term combustion of wood fuel. Only a homemade version will come out much cheaper for the owner. A do-it-yourself metal oven for a garage is a good savings.

To do this, the furnace space is divided into two chambers, the chimney pipe exits the second, and the combustion itself takes place in the first chamber. You can also make a simple single-chamber stove, like a stove from a pipe or a gas cylinder, but the consumption of burned wood will be much higher.

Conclusion

A do-it-yourself metal garage oven is an excellent and economical option for car owners. The material for its manufacture can be obtained literally "underfoot". Old cylinders, rims, pipes, iron sheets will be used. But in order for such a furnace to serve the owner for many years, it is necessary to take only high-quality and thick metal.

Any factory or home-made stoves require mandatory compliance with safety regulations when working with them. Be sure to remember that carbon monoxide is a dangerous and invisible killer, so ventilation and sealing of welds when using such devices should be given increased attention. When working on creating your own stove, you must use personal protective equipment, as well as test ignition of the stove only in the open air.
