Efficient do-it-yourself garage stove. Wood-burning garage oven: DIY

We make a stove in the garage with our own hands

Unlike electric heaters, garage stoves are cheaper to operate - depending on the design, they can be heated with firewood and wood waste, woodworking waste, used engine oil, etc. To minimize financial investments in organizing heating, craftsmen make a garage oven with their own hands.

A homemade stove in the garage is made mainly of sheet iron, thick-walled barrels or pipes. There are also compact brick stoves. The design is selected based on the availability of materials and fuel, the requirements for the functionality of a garage oven - for example, it can be equipped with a hob.

A homemade stove has an open combustion chamber, which means that oxygen for combustion comes from the room. In addition, part of the flue gases enter the air. For this reason, exhaust ventilation must be provided in the garage. The stove is installed away from flammable objects, the wall and floor finishes must be resistant to combustion.

Consider how to make a furnace in the garage, using the example of the most common designs that have proven their effectiveness and ease of use.

Potbelly stove

The metal wood burning stove for the garage is characterized by:

• high level of heating with compact dimensions;
• "omnivorous" - the use of various types of solid fuel is allowed;
• light weight - installation of the foundation is not required;
• the ability to use for heating water and food;
• a simple design that you can do yourself, having the skill of welding.

Metal stove-stove for the garage

Wood-burning home-made potbelly stoves, despite external differences, consist of the following elements:

• firebox (the size of the firewood and the volume of a serving of fuel depend on the dimensions of the firebox, which affects the burn-through time of one bookmark);
• grates (a grate on which fuel is placed) necessary to create traction;
• ash pan (compartment where ash from burnt fuel gets into);
• chimney (a pipe with a diameter of at least 100 mm, which serves to remove flue gases).

Attention! When planning to install a potbelly stove in the garage, decide in advance on the choice of fuel. If, in addition to firewood, it is planned to use coal, sawdust and other types of fine-grained fuel, the size of the holes or the distance between the bars of the grate should be reduced to 15 mm. For wood-burning stoves, this figure can be 40 mm.

The disadvantage of wood-burning stoves is the high rate of fuel burnout, as a result of which a significant part of the thermal energy escapes along with the flue gases. A metal furnace for heating a garage is equipped with a chimney that leads through a wall or ceiling to the street. If the chimney pipe is mounted from several bends located at an angle relative to each other, the air in the room will additionally warm up. If there is free space, a long inclined chimney is installed for the same purpose.

Scheme for mounting the chimney in the stove

For the manufacture of a cylindrical body of the simplest potbelly stove, a 40-liter propane cylinder, a pipe or a metal barrel with a thickness of at least 2 mm is suitable. Sheet iron allows you to make a rectangular stove.

The cylindrical body can be positioned vertically or horizontally, depending on the available space in the room. The vertical stove is more compact, but the size of the firebox greatly limits the size of the firewood.

The branch pipe for the chimney is welded into the hole on the side or lid of the stove. At the gas cylinder, a hole for the pipe can be cut in the center of the upper rounded part, but in this case the stove remains without a hob. To create a more practical unit in a vertical design, a convex cover is cut off from the cylinder and replaced with a piece of sheet metal.

Cylindrical horizontal gas cylinder furnace

If the cylindrical body is horizontal, to create a hob, a steel sheet is welded to the top and its edges are provided with supports for rigidity. Or a metal burner is welded into the body.

A hole for the firebox is cut out in the side of the vertically located cylindrical body and below - for the ash pan, metal doors are installed on them - ready-made or made from a cut-out piece of metal with welded hinges and a valve. A round grate is laid on the corners welded inside the body.

If the body is located horizontally, it can be divided by a rectangular grate into a furnace compartment and an ash pan, while the corresponding doors are installed at the end of the body. The second option is to weld a rectangular box made of sheet iron to the bottom of the body, in which holes are drilled or a grate is welded.

Do-it-yourself cylindrical vertical oven

Potbelly stove with increased efficiency

To increase the heat transfer of an iron stove, it is recommended to make it two-way - that is, to force the hot gas to pass through special channels inside the case, actively giving off heat to the room.

The two-way heater is made of mild steel sheet. It is important to use steel grade St10 or St20, since the construction of high-carbon or alloy steel is less reliable - when heated to high temperatures, the metal hardens, which causes cracking of the welds.

Dimensional diagram for the manufacture of a stove in the garage

Two-way wood-burning garage oven requires the use of:

• sheet steel 4-5 mm thick (for the body, chimneys, firebox and ash pan doors);
• sheet steel 6 mm thick (for the roof of the firebox, which experiences the maximum thermal load);
• pipes with a diameter of 100 mm for the chimney pipe;
• corrugated reinforcing rods with a diameter of 16-18 mm for grate grate;
• rolled metal for the manufacture of legs (profile pipe 40x40 mm, corner with a shelf 40 mm, etc.);
• metal latches, hinges and handles for doors.

The above drawings will help determine the basic dimensions of the elements of the stove. To make it, you need to know how to weld metal with a continuous seam. All seams are checked for strength and tightness.

Increasing the efficiency of iron stoves

A potbelly stove of standard configuration or a two-way stove will be improved in order to increase heat transfer. The easiest way to do this is to weld metal corners or pipes to the body, which perform the function of convective fins. The total heat transfer area increases, plus the intensity of air exchange increases, due to which the room warms up noticeably faster.

A rectangular potbelly stove can be bricked on one or more sides - the masonry will serve as a heat accumulator, and the stove will continue to heat the garage even after the firewood has completely burned out. If the furnace body is cylindrical, a barrel-in-barrel construction is made for the same purpose. In this case, a special backfill between the furnace body and the outer shell serves as a heat accumulator.

The design of the furnace "barrel in a barrel" for heating the garage

The furnace in the garage is made from two barrels of different diameters. At the one that will serve as a casing, cut off the lid, cut a hole for the furnace door in the side part, placing it at least 12 cm from the bottom. The edges of the hole are bent inward, as is the upper edge of the barrel itself. The door is made of sheet iron, several holes are drilled in the lower part for air inflow, hinges, a handle and a valve are welded.

The made casing with an attached door is installed on a channel or brick base (it is important to leave an air gap between the bottom of the stove and the floor, so the base should not be solid). A layer of pebbles mixed with sand, dry clay or soil (not peaty) is poured on the bottom of the casing. The backfill is pre-calcined. Do not use stones of rocks that crack when heated or emit harmful substances.

The backfill layer at the bottom is lightly tamped so that there are no voids left. In the barrel, which will serve as the inner body of the stove, a hole is cut corresponding to the hole in the casing, its edges are also bent inward. In the upper end part of the body, closer to the edge, a hole for the chimney is drilled and a pipe is welded in. The rest of the lid space can be used as a hob if necessary.

The inner casing must be installed along the same axis as the casing so that the backfill layer is the same around the entire circumference. Tiles of brick or stone hewn to size are fixed around the holes for the firebox, they are attached to clay mortar. The rest of the space between the housing and the casing is filled with backfill.

Another improvement option is the creation of a heat gun based on a simple vertical-type potbelly stove from a gas cylinder or a pipe with a wall thickness of 4 mm or more. A detailed diagram gives an idea of ​​​​the device of the heating unit.

Sectional view of the heating device

The lower part of the furnace from a gas cylinder is made according to standard technology. The future heat gun needs to equip a compartment for heating air. For this purpose, the upper part of the body is cut off, a horizontal round plate is welded in, the diameter of which corresponds to the inner diameter of the cylinder. Strips of steel are pre-welded onto the upper part of the plate - they serve as air exchanger fins and increase the heating efficiency.

Air heating compartment with steel fins

From opposite sides of the cover of the resulting air chamber, holes are drilled and branch pipes are welded. On the supply side, a small fan is required to increase the intensity of the air flow. Fan power depends on the size of the room. The chimney pipe is welded below the air chamber.

Homemade oven for heating a garage from a gas cylinder

Such a garage oven is convenient to use and has a high efficiency, but its disadvantages include energy dependence, since electricity is required to operate the fan. The second drawback is that the homemade product does not have a hob.

Heater in operation

A stove in a garage for mining is a convenient option if it is possible to extract liquid fuel inexpensively or for free (such units can run on other oils, diesel fuel). The heater is a fire hazard - it is important to ensure that the fuel does not contain water, otherwise splashes of burning oil will fly out through the holes in the afterburner (perforated pipe).

A do-it-yourself waste oil heater is made from sheet metal, pipes or barrels. The fuel tank and upper chamber may be cylindrical or rectangular.

Waste oil stove design

Guided by the proposed drawing, you can make a classic furnace for testing in the garage. Fuel is poured into the lower tank, a combustible liquid is used to ignite it. The released pyrolysis gases in the perforated afterburner are mixed with air and burn out already in the upper chamber, equipped with an internal partition.

Such a garage stove is easy to assemble, but not very economical - about 2 liters of mining is required per hour of work. During its operation, the smell of burning and fuel is noticeable, the room should be well ventilated.

Dimensional diagram of a homemade waste oil stove

A furnace for working out in a garage can be a design with drip fuel supply. This is a safer option for garage use. There are several options for such heaters, but the principle of the device is general: it is necessary to provide a metered supply of fuel and air flow to the combustion chamber.

Furnace for testing with drip fuel supply

Since the oil pipeline runs along the afterburner pipe, the fuel has time to heat up and evaporate more actively, once it enters the combustion chamber. The walls of a working furnace are red-hot, so the craftsmen from the dropper stove at working out with their own hands create a full-fledged liquid fuel boiler, equipping a water jacket around the body. The water circuit makes it possible to fully warm up your large garage.

A universal option can be called a wood-fired oven and mining. Usually this is a hybrid of a small wood-burning stove, the body of which, if necessary, can serve as the upper chamber of a classic heater for testing. The reservoir for liquid fuel is located outside the body of the potbelly stove and is connected to it by a straight or curved perforated afterburner.

Another option for a hybrid stove:

• the lower part of the body is a classic wood stove;
• the upper part of the housing is removable, it consists of a cover, an afterburner and an upper combustion chamber;
• the afterburner is equipped with a removable casing that turns it into a chimney when the stove is running on wood;
• inside the housing there is a reservoir for liquid fuel, which is removed or inserted depending on the type of energy carrier used.

Hybrid stove for garage heating

When making such a unit, it is required to qualitatively adjust the size and weld all the elements. The convenience of universal stoves lies in the wide choice of fuel.

Conclusion

Having figured out how to make a stove of one type or another, you can choose the best option, taking into account the complexity of the design and efficiency. Making a heating unit in a garage with your own hands makes it possible to optimize the costs of creating a comfortable environment for car repair and maintenance work.

Video on the manufacture of a stove for working out for heating a garage:

Unfortunately, most garages are located far enough from residential buildings and cannot be connected to central heating. This leads to a number of problems, from having to warm up a car that has been sitting overnight in a cold room, to being unable to repair or service the car because the temperature is too cold. Many drivers opt for electric heaters, but this results in high energy bill costs.

A wood-burning stove for garage heating allows you to use it at any time of the year with maximum convenience, eliminating the need to solve the problem of garage heating. After installing a wood-burning stove, you can carry out the necessary repairs and maintenance of the car without experiencing discomfort.

Many garage owners are accustomed to put up with the cold and do not even think about equipping it with permanent heating. The use of heaters is not always convenient and beneficial, and working in the cold is fraught with a decrease in concentration, deterioration in motor skills and hypothermia. If you spend a lot of time in the garage, then having a permanent garage heating in the form of a wood-burning stove is the best solution to the problem.

Installing a wood-burning stove in the garage provides the following benefits:

• The car is kept in optimal conditions. Heating protects against freezing fluid, prevents problems with starting a frozen car, saves you time that would be required to warm up the engine.
• The service life of the battery and other vehicle parts is maximized.
• The conditions of stay in the garage become comfortable and safe.
• The room warms up quickly and stays warm for a long time.
• The wood burning stove is easy to operate.
• It has a small size, which is extremely convenient in conditions of a shortage of usable space.

All these advantages indicate that wood-burning garage heating stoves are the best solution.

Wood stove features

Wood-fired air heating stoves are perhaps the most versatile means of heating. Even the advent of many other types of stoves and heating methods did not put wood stoves out of service. Such ovens can be purchased or even made independently. They are brick, metal and even combined, of various shapes and configurations.

One of the main characteristics of such furnaces is unpretentiousness in the fuel used. It is possible to use wood of various qualities for the stove, burning in it both special firewood and construction waste, waste paper, rags and other garbage.

At the same time, burning wood does not create such harmful waste as other types of fuel, and combustion products are easily removed through the chimney.

Requirements for a wood-burning garage stove

It is impossible to choose the best oven for the garage - each car owner chooses it based on his own preferences, capabilities and other factors. But any oven installed in the garage must meet the following criteria:

• The oven must be safe to operate.
• It should be possible to regulate the temperature in the garage room.
• Installation should be as easy and simple as possible.
• Furnace maintenance should not require special skills and knowledge.
• The furnace must have a high level of heat transfer and efficiency.
• The dimensions of the oven should be small.
• The cost of fuel should be low.
• The stove or the materials for installing it should not be expensive.

A wood-burning stove meets all these parameters, so it may be the best solution for garage equipment. Its operation does not depend on any additional devices. Autonomy allows you to put a wood-burning stove in any garage, whether it is located in a garage complex or near a private house.

Garage wood stove options

If you have decided that a wood burning stove is the perfect option for your garage, you should know that there is more to come. The wood stove itself has several options, so the choice is not yet complete.

First of all, it is worth saying that there are two main categories of stoves that are used in garages and other non-residential premises:

• The so-called potbelly stoves, often home-made, which are designed to heat a garage or other small area and only for a limited period of time. Such models of furnaces are usually used when repairing a car or other work related to a long stay in the garage. They can also be used to warm up the car faster. But they are not designed for long-term provision of heat.
• Long burning stoves. These are larger and more complex stoves, however, they can even provide constant heat in the garage - provided that someone constantly throws firewood into them.

Long-burning stoves are sometimes also made on their own, but this is highly discouraged. The risk is too high that you will make a mistake, and together with a warm garage you will get a smokehouse at best. In the worst case, the oven simply won't work.

Potbelly stove for garage heating

Therefore, it is better to buy long-burning stoves ready-made or order their installation in your garage. If the stove is made by a professional, you can be sure that you are not in danger of cold or poisoning by combustion products.

How to choose a garage oven?

To make the final choice and decide what kind of stove you want to see in your own garage, first of all, start from your financial capabilities, as well as how long the heating season lasts. Another important factor is how soon you need the oven.

If you need it urgently, then a cast-iron stove can be a good option. It is not too cheap, but you can start using it almost immediately after purchase - the main thing. Don't forget to make a chimney. It retains heat well, heating the garage for a long time. However, if you don't have very cold winters, this oven may be too "hot" for your garage. In this case, there is no need to spend money on a cast-iron giant.

There is no point in building a brick oven in a garage, unless your garage is the size of a small house. A brick oven is also quite expensive, but most importantly, it takes a long time to build and is not cheap. However, bricks retain heat very well, so even a metal stove can be overlaid with a protective screen made of bricks.

If you live in a non-harsh climate and don’t spend much time in the garage, an ordinary potbelly stove can suit you. The main thing - do not try to make it yourself, buy a ready-made stove.

Features of long burning wood stoves

Separately, it is worth mentioning long-burning stoves. They allow you to provide constant heat in the garage, so you no longer need to warm up the car on a cold winter morning. The main disadvantage of this option is that a lot of firewood is needed to constantly heat the garage. But if you're willing to pay that kind of expense, investing in and maintaining a long-burning wood-burning garage stove may well be worth it.

The main difference of such models from all other furnaces is that the period of autonomous operation of the furnace can be from 10 to 20 hours. In other words, you do not have to constantly run and throw firewood into the stove. It will be enough to do this a couple of times a day, but you will have to download a lot.

For this, long-burning wood stoves have a special design. A special damper is installed on them, which makes the draft moderate. Firewood in the oven does not burn quickly, but smolders for several hours. Also, the combustion force is regulated by air.

Using a long-burning stove is convenient for a garage, as well as for any non-residential premises. Since you will not be in the garage all the time, a conventional oven will burn through. And the room is cool. With a long-burning stove, you can safely go to bed or go to work, knowing that when you return, a warm and cozy garage will be waiting for you. The main thing is to observe all safety rules when installing and operating such a stove - after all, you can leave the fire unattended only if you are completely sure of its safety for the people around you, and of course, your property.

Safety

Handling fire is potentially dangerous for the health and life of a person, as well as the safety of his property. When installing a wood burning stove in your garage, you should know the basic safety rules that must be followed.

If you put the oven in the basement of the garage, you need to make a hole for air flow. The outlet of the supply channel is located on the street, but not near the ground itself, preferably at a distance of forty to fifty centimeters from its surface. An extractor hood or chimney is also needed - combustion products will be removed in them. The hole for the exit of smoke, carbon monoxide and other harmful substances is made as high as possible - in the ceiling or roof of the garage. At the same time, it is important to locate the inflow inlets and outlets for smoke removal in different corners of the garage. In this case, the use of the oven will be most efficient and safe.

It is also necessary to ensure that there are no easily flammable materials and substances near the stove. For a garage, this is especially important, since gasoline, various rags, oily rags, etc. can be found there. All this must be removed from the furnace as far as possible. Any debris should be removed to avoid an accidental fire.

Finally, you need a place to store firewood. It is better if you can store at least part of the yard under a roof - dry firewood burns better and gives off more heat. However, you also need to store firewood not at the stove itself.

Results

After studying all the examples given here, the pros and cons, arguments and features, you can easily decide whether you need a wood-burning stove in the garage, and if so, what type is better to put it. The most important thing to remember is that the choice, purchase, installation and operation of the stove must be approached as responsibly as possible, only in this case you can feel safe and enjoy the benefits of a warm garage.

As a rule, technical rooms and garages are not connected to centralized heating. But after their construction, it often becomes necessary to warm up such buildings, especially if there is a car there or a workshop is equipped. For such purposes, a garage oven is installed. It should be compact, and also relatively quickly heat up the room to the desired temperature.

  Suitable garage options

  

  Homemade garage stoves are made of steel according to the scheme of a conventional potbelly stove. As a material for the main part, old gas cylinders, pieces of steel pipes or metal barrels are used. Using such spare parts, you can significantly save money and time, since the main part of the hull (sometimes even with the bottom) is already ready.

  Cases are also made from metal sheets. Brick models are sometimes found in garages, but very rarely. This is due to large dimensions, slow heating and low efficiency. The most popular options are those that use firewood as an energy source. But you can use any fuel here (everything that burns).

  As practice shows, such designs have a number of disadvantages, one of which is a strong fuel consumption. Because of this, recently, long-burning stoves have quickly begun to gain popularity. Their efficiency is twice that of conventional models. The most economical of these are top-burning designs. A 50-liter tank from a gas cylinder, completely filled with firewood, can work from 6 to 9 hours. At the same time, the room will always be warm throughout.

  Waste oil stoves are also used for garages. The designs are quite economical, since there is a lot of such fuel in garages. You should also remember about the harm that mining brings. It contains a lot of heavy metals. But the oil construction is one of the most popular.

  Installation of a potbelly stove

  

  Potbelly stoves began to be popularized in the 20s of the XX century and since then they have occupied the first positions. Previously, they were placed not only in technical rooms, but even in apartments. As the main element, a steel pipe or a gas cylinder is most often used. In addition, barrels can also be used, but they must be thick-walled and small in diameter. When using any material, the wall thickness should not be less than 3-4 mm (optimally - 5 mm). Such a device will work for a long time.

  For self-production, vertical and horizontal arrangement is suitable. It is more convenient to use the first option, since the firebox will be compact and roomy. But by placing the stove horizontally, you can use longer firewood. In the case of a vertical shape, they need to be cut finely.

  

  Production of a vertical stove

  A vertical home-made stove for a garage is made from a pipe or a gas cylinder. Conditionally, the segment can be divided into two unequal parts: one large - for laying firewood, and the second smaller - for the ash pan.

  Work is carried out in the following sequence:

  

  

  horizontal shape

  For these purposes, an old gas cylinder is ideal. The ash pan is welded at the bottom of the structure. Holes should be made in the cylinder itself, which will play the role of grate (pass through the ashes). To remove smoke, a chimney is welded on top of the structure. To do this, you can use a cut pipe. Its edge is welded, adjusted to the angle of the side of the cylinder, that is, it must be semicircular. After checking the welds, the ring inside is cut out with a grinder or a cut-off saw for metal.

  Next you need to make the legs. For these purposes, steel corners welded on the underside of the cylinder are well suited. Platforms (rectangular pieces of thick steel sheet) are also added to them, which will make the structure stable. Then the doors for the ash pan and the main part are cut out. Gaps in the ash pan are acceptable, air will pass through them for the combustion process. The hole for laying firewood must be completely closed with doors without gaps. Thus, it will be possible to regulate the air supply and the intensity of combustion.

  
  

  Homemade garage ovens are sometimes made with a cast-iron door. The process for doing it yourself is a bit more complicated. To do this, the metal frame for the cast plate is first welded. The two parts are fastened with bolts. After that, loops are welded to the frame and body (the “mother” part to the body, and the “folder” to the frame). The door is mounted on hinges.

  Original long-burning potbelly stove

  Use of two barrels

  You can also weld a stove in the garage from two barrels. People who have used a classic potbelly stove know that during operation it heats up very much (sometimes to red) and gives off very strong radiation. The craftsmen quickly solved this problem and came up with a design of two barrels of different diameters placed inside each other. The distance between the barrels is covered with a mixture of pebbles and sand, which needs to be heated and already cooled down to fall asleep. The inner barrel will be used as a firebox, and the outer one just as a body.

  Long burning

  Do-it-yourself wood-burning garage stoves can be made according to the principle of long burning. There are many varieties of such structures. For example, the bubafonya stove, which began to gain popularity dramatically about 5 years ago, is today used by many homeowners. The big advantage of this model is that not only firewood can be used as fuel, but also other combustion products, for example, shavings or sawdust. There are craftsmen who remake the “boubafonya” (it was popularly named after the author) into a heating system for a garage. It is enough to make a water jacket and dilute the pipe system.

  A very big disadvantage of this model can be considered the need to turn the whole body over in order to shake out the ash. With a welding machine, this option is easy to make, even with minimal work skills.

  Scheme and principle of operation

  Long-term combustion is provided due to the specifics of the process. Firewood burns from above, and the flame goes down as the upper layers burn through. In this regard, the flame spreads much more slowly. Almost immediately after the start of operation, the stove generates a large amount of heat. In the classic version, the design has a cylindrical shape. The barrel stands upright without a lid, but with a bottom.

  Garage heating. Super - cylinder stove "100% efficiency" / Propane wood stove

  The main structural elements are:

  • cylindrical barrel;
  • cover with a hole and handles;
  • "cargo" with a welded pipe (for supplying air and pressing firewood).

  Having made a stove in the garage with your own hands according to the drawings, you can begin to check the work. The principle of operation of such a stove is simple. The body is completely clogged with firewood mixed with sawdust and the bookmark is set on fire. The pipe that supplies air to the primary chamber is closed with a lid, and when the bookmark is strongly ignited, the barrel is also closed with a lid. The pipe itself has many holes, so the air for constant combustion is always supplied.

  The design has a secondary and primary combustion chamber. They are separated by the so-called cargo - a circle of a slightly smaller diameter than the barrel itself. In the primary combustion chamber, firewood is laid and burned. Combustion products (gases) enter the secondary chamber through the gap formed at the “load” level. They are in a well-heated oven again, heating the oven even more. The lid of the barrel cannot be made airtight, since combustion air will flow through the slots, and this will increase the draft, which is also important in such a design.

  
  

  The burning gases in the upper part give no less heat than the firewood itself in the primary combustion chamber. Therefore, this design is very efficient. It gives off two or more times more heat than an ordinary potbelly stove. During the burning process, the load will lower, pressing down on the wood until it is all burned. After burning a complete bookmark to the ground, you can put a new batch of firewood and start the process all over again. After the secondary chamber, the gases exit through the chimney. It is necessary to throw away the ashes after several bookmarks. All firewood burns completely. At the end, only ashes and a few coals from the lower balls remain.

  Do-it-yourself potbelly stove...

  Unit modifications

  The most inconvenient thing is the need to turn the structure over in order to pour out the ash. Solving the problem is simple. It is enough to mount the grate and the bottom of the ash pan. But this method also has its drawbacks. A lot of air will flow through the gaps formed, and the firewood will burn faster.

  And for the original design of long burning, smoldering is characteristic, and not burning, so the option is not the best. If you make the door airtight with all seals, then you can solve this problem.

A simple do-it-yourself wood-burning garage stove can be made from different materials - brick, an old gas cylinder or a metal barrel with thick walls. A wood-burning stove can also be made from a piece of thick-walled pipe.

The main thing, when installing a solid fuel stove in the garage, is to equip the room with good ventilation - forced or natural.

It is easy to make the following solid fuel furnace designs on your own:

• - reliable and safe, requires some bricklaying skills;
• potbelly stove - easy to make from pipes, cylinders or thick-walled barrels;
• long-burning wood-burning stoves - you need a cone firebox (cylinder, pipe) and a welding machine;
• waste oil stove - you will need pipes, a drill, welding and a diagram drawing. Be sure to protect the oven from moisture and dampness.

If we compare the designs, then potbelly stoves heat up quickly, but do not hold heat, unlike bricks. Long-burning stoves require strict adherence to the dimensions according to the scheme, and waste oil stoves cannot be installed in garages made of flammable materials.

Option one - reliable and efficient brick

Ordinal bricklaying scheme in a simple garage oven

Brick wood burning is a traditional reliable heating option. Compared to metal boilers and potbelly stoves, brick is safer, but such a furnace heats up longer, and it also cools down.

In order to fold a brick oven on wood with your own hands, you will need the following materials:

• refractory brick;
• high-fat clay for masonry mortar. It is easier to buy a ready-made refractory mortar for laying refractory bricks, it contains all the necessary additives.

Advice. We check the fat content by rolling a ball out of wet clay. If such a ball thrown on the floor cracks, then the clay is not suitable - low elasticity (fat content). Soak the masonry clay for at least 24 hours before mixing the mortar.

• cement M300 and sand for the cement foundation of the stove;
• doors for the blower and firebox;
• grate material;
• asbestos thread for sealing;
• chimney damper;
• chimney pipe - asbestos or two-layer stainless steel.

Advice. If you make the chimney removable, then in the summer it will be possible to use the hole as additional natural ventilation.

We choose a place for the stove so that the chimney does not come into contact with the roof slab, and the stove does not interfere with movement.

The sequence of laying a simple brick stove for a garage, dimensions 60x60 cm, this is quite enough for a standard garage:

• the foundation for a small oven should not be made powerful, 50 cm is enough. If a high oven is planned, then additional reinforcement of the foundation cement screed can be performed.

Note. If there is a concreted cement screed in the garage, then the foundation for the stove can not be poured.

• after the cement has hardened, it is necessary to lay 2 layers of waterproofing (roofing material) and you can start laying the furnace;
• solid base of the furnace - two solid rows of bricks;
• we expose the ash pan door, fixing it with wire on four sides for rigidity. The wire is fixed with masonry mortar;
• ordering a brick oven for a garage - the laying order is easier to understand by watching the video material.

In the process of laying, we check each row with a water level, it is important to observe the horizontal and vertical. Installation of the grate additionally requires sealing with asbestos thread.

It is possible to upgrade a brick oven of the “rocket” type, in which case the heat transfer is doubled by using the heat of the chimney pipes.

When a brick oven is built with your own hands, you cannot immediately test and melt it. It is necessary that the masonry is completely dry.

Option two - homemade potbelly stove

With a potbelly stove welding machine, proven and simple designs can be made in one day. Thick-walled pipes, barrels and gas cylinders can be used to fire a potbelly stove. A rectangular potbelly stove can be welded from a metal corner and steel sheets (3 mm thick).

Important rules for the location of the potbelly stove in the garage

In order to avoid fire, the following fire safety rules must be observed when installing a homemade potbelly stove:

• distance to walls and flammable objects - meter, to a brick wall distance - 0.5 meters;
• the walls and ceiling around the stove are additionally sheathed with sheets of metal;
• a thick metal sheet is placed under the stove - 10 mm or a cement screed is made - a thickness of 20 cm;
• a ventilation device (forced or natural) is required so that no troubles occur during smoke. A gap under the garage door of 5 cm or two exhaust holes under the roof will ensure sufficient natural ventilation of the room.

The distance from the stove to the car must be at least two meters. In close contact with the hot walls of the furnace, there is a possibility of paint damage or fuel fire.

An additional protective casing made of brick walls will not only create a convection flow of warm air and increase heat transfer, but also ensure safety.

Note. Bricks can only be laid over square or rectangular potbelly stoves. A furnace in the form of a cylinder requires a special design of the casing, in the form of side metal ribs. A brick casing for the cylinder will reduce heat transfer and lead to rapid burnout of the walls.

How to make a simple square potbelly stove

For a standard garage, a heater 30 x 30, 50 cm high is enough. The diameter of the pipe for a potbelly stove is not less than 30 cm, the wall thickness is not less than 5 mm. For a chimney, a pipe with a diameter of 12 - 15 cm, a thickness of 3 mm, is suitable. So that the chimney pipe does not quickly freeze over, it is wrapped around the outside with a layer of mineral wool.

Work order:

• first we draw a cutting of the details of the stove, we determine all sizes;
• we cut out the necessary parts from sheet metal to size;
• first we connect the walls and the bottom of the furnace by welding, but we only grab it. To be able to set all sides strictly according to the level;
• after checking the vertical and horizontal, all joints can be welded with a tee seam;
• install the lower partition into the finished case. It is immediately necessary to drill holes in it to remove ash (the step between the holes is one and a half centimeters, from the walls - 5 cm);
• the partition is located no lower than 10 cm from the bottom;
• in the back wall we cut out a circle for installing the chimney pipe;
• firebox and blower doors - distance from the wall - 5 cm;
• when attaching the door curtains, you need to take into account that they will sag from the temperature, so we fix them 2 cm higher;
• the last to mount the legs of the potbelly stove - a height of at least 15 cm and install the top sheet of the furnace.

In order to get maximum heat transfer, the potbelly stove pipe should not be straight. It is necessary to install pipes with two turns of 30 degrees and bring them out through the garage wall. Then the products of combustion will give all the heat not to the street, but to the room.

The video shows how to make a simple potbelly stove from a metal sheet and corners and from an old gas cylinder.

Option three - waste oil stove

This heater gives maximum heat transfer and practically does not require fuel costs - there is always used oil in the garage. The only disadvantage of this stove is that you need a high chimney, and the products of combustion create soot, which will have to be cleaned often.

Mini rims for cars. We watch the video, to make such an oven is a couple of trifles.

Option four - long-burning wood stove

It is difficult to maintain a positive temperature in the garage, especially in a metal or profile structure, even insulated. Therefore, long-burning stoves are the best solution for a garage, where you just need to keep the temperature above zero so that you don’t warm up the engine every day and don’t spoil the candles and don’t put the battery down.

Such a stove can be made from an old gas cylinder, metal sheets and even bricks. The point is that in such a furnace, air access to the furnace is limited and the firewood does not burn, but smolders, maximizing the efficiency of the fuel.

Laying firewood in such a stove from above, the fuel is pressed as it burns by a metal piston.

From a simple old barrel, you can make a heater for a garage that runs on sawdust, tyrs and construction waste.

Even by making a long-burning stove with your own hands completely correctly, you can not achieve maximum heat and firewood consumption will be large. The reason is incorrect fuel loading. Firewood in the oven cannot be stacked vertically - only horizontal laying.

The video describes the reasons why the fuel in the stove with the top laying of firewood does not burn out completely.

As a conclusion - is it possible to heat a garage with such a wood-burning stove? If you follow important safety rules, then such heaters are an excellent alternative solution for small garages without an electrical connection.

What is important to remember:

• high-quality ventilation of the garage is needed to avoid waste during smoke and fire;
• it is necessary to protect the metal parts of the heater with a casing made of fire-resistant materials;
• the chimney must be removed so that it does not come into contact with the wooden roof rafters;
• from the hot walls of the stove to the car must be at least two meters;
• water from the chimney must not be allowed to enter the furnace; a protective cap must be installed on the pipe;
• choose durable materials for the oven;
• a waste oil stove can explode if moisture gets into the furnace;
• so that the condensate does not flood the chimney, it is insulated with mineral wool with foil or removable galvanized pipes with internal insulation with mineral wool are installed.

The safest option for any garage is a long-burning brick oven or, protected by a refractory brick casing.

In the autumn-winter period, staying in an unheated garage is not a pleasant process, and installing traditional heating is an expensive pleasure. Therefore, for the most part, the owners choose economical options and install compact, energy-efficient garage stoves. The design should warm up well, heat the air evenly and be safe at the same time.

The project of most garages does not provide for the installation of a heating system. At the same time, low temperatures in winter not only create discomfort for car owners, but are also undesirable for vehicles. As practice shows, the use of traditional portable electric heaters is ineffective and results in a round penny in the form of electricity bills. Solving the problem is quite simple - you need to build a stove in the garage with your own hands, choosing the best option.

At the heart of the garage heating problem are two points:

• lack of effective thermal insulation;
• the square-cube law, which implies the ratio of the size of the surface of a body to its volume.

The mentioned law is reflected in the form of heat losses. To heat one cubic meter of a room with a small area, much more heat is required than when heating a spacious building. For example, a 10 kW device is enough to heat a two-story house, and a standard-sized garage will require a device with a heat output of 2.5 kW.

In order to maintain a temperature of 16 ° C in the garage, you can install a unit with a power of 2 kW, and for a temperature regime of 8 ° C, provided for storing a car, a unit with a power of 1.2 kW is enough. Accordingly, in order to warm up the entire area, much more thermal energy will be required, therefore it is better to heat not the entire room, but the so-called workplace.

How to make an oven in the garage: maximum placement efficiency and insulation system

The air heated by the heating furnace for the garage should be concentrated in the center of the room, spreading around in such a way that a small layer of cool air forms between the walls and the ceiling. Thus, the vehicle and its owner will be in a comfortable temperature zone, and heat consumption will be significantly reduced. The so-called thermal cap is formed due to natural convection: a strong flow of warm air rises, where it collides with a cold dense layer.

Helpful advice! According to the rules (regarding car parking), regulated by document SP 113.13330.2012, the optimum temperature for car storage should not be lower than 5°C, and during repair work - 18°C.

Thanks to the physical process of convection, which consists in the distribution of warm air currents, almost the entire garage is heated efficiently. You can get this result even with a homemade garage oven with low power.

An important role in the process of heating and heat preservation is played by the insulation system. One of the tricks that the builders of garage cooperatives use is the dense arrangement of neighboring buildings, which allows you to save heat as much as possible. In individual buildings, various available materials can be used for external insulation, for example, fiberboard.

Warming a metal garage inside can be problematic, as a dew point appears at the point of contact between materials, where condensation accumulates. As a result, this can lead to rapid wear of both the base material and the insulation. Therefore, it is necessary to maintain an air cushion between the main and additional walls of 30-50 mm, retreating from the floor by approximately 60 mm.

Varieties of stoves for the garage: choosing the best option

In the garage, it is allowed to install a variety of heating systems that operate on various types of fuel: liquid, solid, electric or gas. The main conditions - the unit must have a high efficiency, while having a low cost and a low level of resource consumption. In addition, the device must be mobile and secure.

For heating the garage, various units are used, which differ in the principle of operation, type of fuel and operating features.

Furnaces for a garage on wood of long burning. The principle of operation of such devices is the converter combustion of fuel. The unit requires professional installation, but experienced craftsmen can make it on their own. Wood, pellets, peat, coal and other exclusively solid fuels are used as fuel. Gas and liquid combustible materials are not applicable. Additionally, it is necessary to install a chimney and an insulation system. Belongs to the category of expensive devices.

Potbelly stoves for the garage. A compact, convenient and affordable version of the oven, which is easy to build yourself using a basic drawing. The main disadvantage of bourgeoisie is an increased threat of fire.

Garage furnaces for working out are the most economical option, operating on engine oil, which has already worked out its resource in the engine.

A brick oven for a garage allows you to get soft heat for a long time, but subject to full warming up. Therefore, this option is suitable for people who work in the garage every day.

Infrared heaters. Such equipment is not suitable for metal structures and half-brick structures. Metal does not reflect well, and brick absorbs such energy, which leads to low efficiency of this type of heating.

Important! During the installation of the heating system, the construction of a high-quality and reliable ventilation system and chimneys is required.

Stove for a garage on long-burning wood: types and principle of operation

Any option for garage stoves has its pros and cons, and at the same time, each of them can be made by hand. To have an idea about the process of creating the unit and calculate your strengths and resources, it is worth getting to know each type of device in more detail.

The popularity of long-burning garage stoves lies in their efficiency, since when burning ordinary firewood, you can get the maximum amount of heat. The principle of operation is that a large amount of fuel is loaded into the combustion chamber at a time, where the process of long-term combustion is due to poor access to oxygen. Thus, firewood does not burn instantly, but gradually smolders, releasing combustible gas.

Furnaces for a long-burning garage can be different in their design features, a popular variety is Bubafonya. The name of the unit comes from the name of its inventor. The high efficiency of the design lies in the fact that such a long-burning furnace can work on sawdust. If you try, then Bubafonya can be connected to a water heating system. In this case, the principle of operation of the device will be to create a water jacket around the boiler.

Buleryan is also a popular model of a long-burning stove, its design is very unusual. The device is widely used not only for service, but also for residential premises. This is a kind of modern hybrid of a classic potbelly stove and a long-burning stove. The unit works by forced convection. Several curved pipes go to the firebox from below and from above. Cold air enters through the lower ones, which instantly heats up in the furnace and comes out already hot from above.

Do-it-yourself long-burning oven for a garage

Despite the relatively complex design, a long-burning stove can be made independently. Such a model will have one, but a significant drawback: to rake out the ash, you will have to turn a rather weighty body upside down. To build a unit, you need a metal cylinder, a welding machine. You can take a square container as a basis, but subject to the normal provision of smoldering firewood. The manufacturing process itself in this case will take several hours.

Most often, for the production of a long-burning furnace, a thick-walled metal barrel with a capacity of about 200 liters is used. From above, they make fasteners for a lid with a chimney, and also make a small hole necessary for the access of oxygen, which is needed for the combustion process. The chimney is approximately 15 cm in diameter, and the air duct is 10 cm. Often the chimney is led out from the side, and a place is left for air to enter from above.

Helpful advice! For a wood-burning garage stove, you need to purchase dry fuel. It is necessary to choose such types of wood that emit a minimum amount of resin during combustion.

An important detail of a wood-burning garage stove for a long-burning garage is a load to provide a press for smoldering firewood. It can be made from a metal circle, the diameter of which should be a few millimeters smaller than the dimensions of the combustion chamber, and two sections of channels that act as a weighting agent. In the weighting circle, it is necessary to make an air duct and weld a pipe with a cross section of 10 cm to it. Its length must exceed the height of the stove body .

Do-it-yourself hole with a door for loading firewood into the garage stove is made on the side, and a grate and an ash container are installed below. The final touch is the welding of the legs at the bottom of the finished furnace.

Stove-stove for a garage: the principle of operation and manufacturing features

An ordinary potbelly stove, popular in the 20s of the last century, is considered the most popular option for a garage stove for wood and other types of solid fuels. It can be made from a variety of improvised materials. Both sheet metal and a piece of pipe, an old barrel or a used gas cylinder will be appropriate here. For successful production, the material must meet the following requirements:

• metal thickness - at least 5 mm;
• the capacity of a cylindrical shape in cross section should exceed 30 cm.

The composition of the classic potbelly stove includes the following elements:

• body with grille;
• loading door;
• ash pan;
• chimney lateral or vertical.

For the manufacture of the chimney, a metal pipe 3 mm thick is used, having a cross section of at least 12 cm. The combustion chamber is cut from the selected workpiece. The grate for fuel is installed at the bottom, and under it is a box for collecting ash made of metal 3 mm thick. The chamber is closed from above and the chimney is removed. The legs for the stove are made of metal corners.

Before you make a potbelly stove in the garage, you need to decide on its shape, which depends on the base material. It can be round or square. It is also important to think about safety rules. Install the stove on a flat and solid base made of fire-resistant materials. Walls also need to be protected from fire. Near the potbelly stove should not be foreign objects.

It is important to take into account that the metal surface of the potbelly stove will become very hot during operation, therefore, in order to avoid serious burns, it is necessary to exclude the possibility of people and animals touching it.

The procedure for making a vertical potbelly stove in the garage with your own hands

The most popular version of a do-it-yourself potbelly stove for a garage is a metal stove. In order to make a vertical unit, the workpiece is conditionally divided into two parts. The smaller one will be located below and serve as a place for collecting ash, and the upper part (base) will be a furnace, and firewood will be laid into it.

Helpful advice! When working with an old gas cylinder, you need to be extremely careful. First of all, you should make sure that there is no gas inside the container. You can completely displace it by filling the balloon with water. There are cases when gas residues in the process of sawing a cylinder provoked an explosion.

As an illustrative example, consider the procedure for manufacturing a furnace for a garage from a gas cylinder:

1. Cutting doors: upper - for the firebox, lower - for collecting ash. They do it with the help of a grinder. The cut pieces are not thrown away, they will serve as doors.
2. Welding grates. To do this, use pieces of reinforcement made of steel of the appropriate length, 13-15 mm thick. A distance of 20 mm is left between the grates.
3. Chimney construction. For this purpose, a metal pipe about 10 cm high is attached to the top of the structure.
4. Locks and hinges are welded to blanks-doors. Connect all the details. To create a seal on the door from the outside, metal strips 20 mm wide can be welded.
5. Installation of legs at the bottom of the product from metal corners.

By the same principle, a potbelly stove is made in a garage from a pipe. The difference lies in the need to weld the bottom and top cover, where a hole for the chimney is prepared in advance. A gas cylinder can also be used to build a heat-efficient rocket stove for a garage.

Instructions for making a horizontal oven for a garage with your own hands

The horizontal design is considered more convenient in terms of loading long logs, but at the same time it takes up more space in the garage, so it is not suitable for a small room. In a horizontal potbelly stove, an ash collection box is placed below. To do this, a blank is made from a piece of channel, and holes are made in the furnace part. Thus, grates and a collector for ash are obtained.

The chimney is placed in the upper part of the housing. For this purpose, a piece of pipe of the appropriate diameter is welded. For the legs of the product, pieces of a metal corner with welded flat blanks of sheet iron are used. This is necessary in order for the structure to become stable. The blower is placed on the side - in the opposite part from the chimney. To do this, a piece of metal is cut out in the wall, which is subsequently used as a door.

You can build an original, more practical and safe oven for heating a garage from two barrels. A metal potbelly stove, unlike its cast-iron predecessor, heats up much faster and it is almost impossible to be near it. This problem can be solved by using two barrels of different diameters by installing one of them inside the other. In this case, the inner barrel is a firebox, and the outer barrel is an additional frame. The space between the walls can be covered with sand or pebbles.

Such a stove will heat up much longer, but at the same time it will cool down much more slowly. Therefore, the required temperature will be maintained in the garage much longer, and staying in it will be more comfortable.

Helpful advice! Small wings welded on the sides of the stove from a pipe will help to increase the heating efficiency of the potbelly stove. These details will increase the area of ​​​​contact of the heated metal with air, which will help warm the room faster.

Do-it-yourself brick garage oven

Homemade brick ovens are also used to heat the garage, although much less frequently. This design radiates heat for quite a long time, but it will take a lot of time to warm it up. Such a unit is suitable for those owners who spend a long time in the garage and go there every day. In this case, you can simply keep the fire in the firebox by throwing firewood.

To equip a small brick oven in a garage with a hob, you will need:

• ceramic refractory bricks - 290 pcs.;
• door for the combustion chamber 250X200 mm - 1 pc.;
• grate for grate 250X250 mm - 1 pc.;
• door for blower 120X120 mm - 1 pc.;
• gate valve 120X120 mm - 1 pc.;
• cast iron plate 70x30 cm.

For laying bricks, it is necessary to prepare a clay mortar. The thickness of the seams should be from 5 to 15 mm. Before you install the oven in the garage, you need to take care of preparing the foundation. Its horizontal dimensions should be approximately 20 cm wider than the device itself.

For the firebox, it is necessary to carry out a lining, providing for the laying of fireclay bricks on a similar solution. Under the casting of the furnace, the bricks are undermined, and under the grate, stove and doors, the base should be wider than the dimensions of the casting. In order to provide thermal insulation, an asbestos cord is used; mineral wool strips are also acceptable, which can withstand temperatures up to 1200 ° C.

Brickwork, performed according to the established scheme, on average consists of 15 rows. Approximately 6 of them install a valve that allows you to switch the furnace to different temperature modes of operation, which is especially convenient in the off-season. In order to have an idea about the future brick stove and so that you do not have to correct mistakes later, it is better to carry out preliminary laying without mortar.

Economical and energy efficient garage ovens

A waste oil furnace is considered the most economical, as it eliminates additional fuel costs. If you correctly calculate the materials and strictly follow the manufacturing instructions, then it will not smoke and pollute the air excessively. The operation of such furnaces on transmission, machine or transformer oil is envisaged. A diesel oven for a garage functions on the same principle.

Structurally, the unit consists of two containers, which are interconnected by a perforated pipe with many holes. If a decision is made in favor of installing a working furnace in the garage, then it is necessary that it meets the following requirements:

• maximum weight - 30 kg;
• capacity - up to 12 liters;
• standard size - 70x50x30 cm;
• average fuel consumption - 1 l / hour;
• exhaust pipe diameter - 100 mm.

To build such a structure is quite simple. No nozzles and droppers are needed to create it, so special knowledge, skills or experience are not needed to make it.

Helpful advice! Before you build a mining stove, it is advisable to first agree with the owners of neighboring garages on the collection of used oil. The container must be made of metal with a thickness of at least 3 mm.

Directly for the manufacture of the furnace will require the following materials:

• steel pipe;
• two metal containers;
• steel corner.

The container can be the case of an old unusable refrigerator compressor or a gas cylinder. The furnace for a garage for mining should be made of a material with a thickness of at least 4 mm, since it is supposed to be heated up to 900 ° C, so thin metal will simply burn out.

The sequence of manufacturing a stove in a garage, functioning at a test

For a mining garage, it is beneficial if there are large stocks of it

The process of creating this type of stove in the garage with your own hands includes the following steps:

1. Installing the lower container on the legs. For this purpose, parts with a size of 20 cm are produced from a metal corner, on which the container is welded in a horizontal position.
2. Cutting a hole in the middle of the lower part of the body, which serves as a firebox and a fuel tank, welding a vertical pipe to it, connecting both containers. It is desirable that the upper part is removed. This is necessary for cleaning the burner.
3. Drilling about a dozen holes in the pipe at a height of half a meter. The first hole must be at least 10 cm from the main body of the oven.
4. Making a hole on the top of the furnace tank for pouring oil and a lid that will help regulate the level of heating of the room and the combustion process itself.
5. Welding a branch pipe on the upper tank.
6. Construction of a galvanized steel exhaust pipe at least 4 meters long and fastening it to the nozzle.

Painting will give a presentable look to the garage stove. For this purpose, a mixture of silicate glue, crushed chalk and aluminum powder is used.

Disadvantages of a furnace for a garage for working out, features of operation

To use such a stove, in order to avoid emergency situations, it is necessary in accordance with clear instructions. To do this, using the lower opening of the furnace, it is necessary to put a small amount of kindling paper into the fuel tank. Next, approximately 1 liter of used oil is poured. The paper is set on fire and wait a couple of minutes until the oil boils. When the oil begins to burn slowly, it must be added as necessary in the amount of 3-4 liters.

Despite the many advantages of this type of garage oven, it is necessary to mention their disadvantages, in particular:

• a very long chimney, which must be at least 4 meters in height;
• it is required that the chimney device be strictly vertical, without bends and horizontal sections;
• The oil containers and the chimney must be cleaned regularly - about once a week.

Helpful advice! To avoid the inconvenience associated with frequent cleaning of the tank and chimney, the design with removable parts will help.

The process of creating a heating system in a garage must be approached responsibly so that such structures as a mining boiler, a brick oven, a do-it-yourself potbelly stove are profitable and bring maximum heat. It should be noted that economical options must be carefully looked after, and brick structures require a certain time for kindling. To create a long-burning metal furnace, certain skills and knowledge will be required. At the same time, any of the options considered, under conditions of proper construction and subject to the rules of operation, will make the garage warm and comfortable.
