For a comfortable stay of a person in a room such as a small garage, it is necessary to maintain a comfortable air temperature in it. This will help you make a stove that you can make yourself. How to weld a stove for a garage yourself and what you will need for this will be discussed in this article.
Collapse
Materials for making homemade garage stoves can be:
- Metal barrels;
- Wheels from trucks;
- Used gas cylinders;
- Pieces of sheet steel;
- Pipe sections.
What to make a garage stove from is up to the car owner to choose, based on the availability of the material and the type of fuel. Homemade stoves can operate on wood, coal, waste engine oil or diesel fuel. It should be remembered that making gas stoves yourself is not recommended and is life-threatening.
Making a garage stove from a pipe
Below is a photo of a DIY pipe stove for a garage:
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;
- Pipe for attaching the chimney, 40 centimeters long and 150 - 200 millimeters in diameter;
- Metal sheet 4 - 5 millimeters thick;
- A piece of metal 3 centimeters wide for the side on the stove lid;
- Channels or corners with an edge of 50 - 70 millimeters;
- Grate for the grate, the length of the pipe and the width equal to its diameter;
- Metal handles (for the body and lid) in the amount of 4 pieces.
Tools
You can assemble a stove from a 500 mm pipe for a garage with your own hands using tools and devices such as:
- Electric welding machine;
- Set of files;
- Hacksaw for metal;
- Hammer or sledgehammer;
- Building level;
- Roulette;
- Marking tool – ruler, core, marker.
Don’t forget about personal protective equipment: welder’s mask, gaiters, gloves, protective suit with fire retardant impregnation.

Assembly procedure for the furnace unit
After completing the work, you need to install the stove on a solid base, alternatively, on four bricks. Next, you should connect the chimney to the pipe and test fire the stove. This is necessary in order to ensure 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 invisible gas - carbon monoxide, which has no odor. Therefore, smoke removal issues should be treated with great responsibility.
Making a garage stove from old rims
This method is quite popular among motorists, since old unnecessary wheel rims can be found at any car depot or garage cooperative. The undoubted advantage of such designs is the large thickness of the metal of car wheels; such a design will not burn out for a long time and will serve its owner for many years.
Below is a photo of a DIY garage stove made from wheel rims:
Materials
Only disks of substantial diameters will be used, for example, from trucks or special equipment with large wheels - tractors, graders, etc. How to weld a stove for a garage from rims and what materials you need for this:
- Two or three car rims. It is better to use stamped ones, as they are made of thicker metal. But light alloy wheels with an admixture of aluminum cannot be used; such a furnace will simply melt during operation.
- Corners or channels for legs, 4 or 6 pieces, 25 - 30 centimeters each.
- Hinges for the door.
- Bolts and nuts.
- Sheets of metal 4 - 5 millimeters thick.
- Two circles, with a diameter the size of the edge of the disk rim (for the bottom and roof).
- A pipe with a diameter of 125 - 150 millimeters for the chimney outlet.
- Round grate.
Tools
The tools used to create a stove from disks are almost the same as those used to create a stove from a pipe, but there are some differences. List of what you will need during assembly:
- Electric welding machine;
- Cutting torch (if available), but you can do without it;
- Angle grinder or grinder;
- Electric drill;
- Hand hacksaw for metal;
- Hammer or sledgehammer;
- Set of files;
- Pliers or pliers;
- Marking tool – ruler, core, marker;
- Building level;
- Roulette;
- Paint brush.
Manufacturing schemes

Assembly order
A vertical stove made from old wheel disks can work on the principle of a Buleryan stove or a stove for long-term combustion of wood fuel. Only the homemade version will be much cheaper for the owner. A do-it-yourself metal stove for the garage is a good saving.
To do this, the furnace space is divided into two chambers, the chimney pipe comes out of the second, and the combustion itself occurs 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 DIY metal stove for a garage is an excellent and economical option for car owners. The material for its manufacture can be obtained literally “under your feet.” Old cylinders, rims, pipes, and sheets of iron will be used. But in order for such a stove to serve the owner for many years, it is necessary to use only high-quality and thick metal.
Any factory or home-made stoves require mandatory compliance with safety regulations when working with them. It is imperative to remember that carbon monoxide is a dangerous and invisible killer, therefore, increased attention should be paid to the issues of ventilation and sealing of welds when using such devices. When working on creating your own stove, you must use personal protective equipment, and also test fire the stove only in the open air.
←Previous article Next article →Centralized heating for most garages that are located far from home is not technologically provided. In winter, a conventional electric heater almost cannot cope with the problem: electricity bills rise, but the amount of heat remains virtually unchanged. There is only one way out of the situation - to make a wood-burning stove for the garage.
This stove will provide great warmth in the winter cold.
Garage heating rules
Garages are almost never insulated from the outside for one reason - this is a rather expensive undertaking for a room in which people are not often present. Yes, and this cannot always be done, for example, in cooperatives, garages are placed quite close to each other, the distance does not make it possible to install thermal insulation.
But the internal insulation of this building can also be very problematic. During the installation of thermal insulation on metal walls, a “dew point” appears at the contact area, that is, a place where condensation begins to accumulate. Almost always, when in contact with moisture, thermal insulation deteriorates very quickly.
And this situation can have a negative impact directly on the garage. In a metal building, you can make thermal insulation, but it is advisable to install the insulation at a certain distance from the wall, approximately 3-6 cm. It is necessary to retreat 6-8 cm from the floor. It is advisable to choose washers as a profile in order to prevent a closed circuit under the floor.
In this video you will learn about the original method of making a long-burning potbelly stove:
During this installation method, condensation will still begin to accumulate, but due to air circulation, the moisture will gradually begin to evaporate without causing significant harm to the room. But for a regularly heated garage, this method is not suitable, since the humidity inside the building will be very high most of the time. This can put both human health and the condition of the vehicle at risk.
As a material for “ventilated” thermal insulation, it is recommended to use slabs, for example, chipboard or fiberboard, that is, self-extinguishing wood materials. In this case, the thickness of the slabs must be at least 5 mm. Ondulin or its analogues are excellent. These plates have the ability to block infrared radiation, which ensures high-quality heating of the room.
But plastic, which even has a damping effect, is prohibited from being installed in a garage. During a fire, this material emits toxic fumes, which can cause poisoning to people in the room. Also, slabs containing asbestos cannot be used as thermal insulation.
When insulating a cold masonry garage, it is recommended to first plaster the walls to protect them from moisture. The metal walls of the building must be painted in several layers, having primed the surface before doing so.
Methods of heating a room
Taking into account the peculiarities of the garage heating system, the stove is required to meet a number of characteristics that it must meet.
A wood stove is the most economical The basic requirements for heating equipment are as follows:
- use of liquid and solid fuels;
- the oven must be small in size;
- ability to maintain high temperature for a long time;
- have a quick warm-up;
- inexpensive cost;
- simplicity of design;
- ease of maintenance;
- ease of use.
Taking into account these requirements, furnaces are classified into different types.
This division is based on the type of coolant used:
- Electric stove. There are no questions about the heating efficiency of this stove, but the cost of heat for a garage space will be quite expensive.
- Solid fuel stove. It has low manufacturing costs and creates an excellent thermal effect.
- Gas equipment. It is most convenient to use in cases where there is a central gas main nearby.
The optimal solution, which is popular among many car enthusiasts, is a wood-heated stove. This stove can be bought in a store or made by yourself.
Let's make an economical stove with our own hands:
Types of wood stoves
There are various ways to make your own wood-burning stove for the garage. For this building, as a rule, the following heating equipment options are selected:
There are certain advantages and disadvantages to any of the methods for making wood-burning garage stoves. At the same time, we must not forget that some heating equipment can be combined with each other to increase the possibility of heating the garage and make it more profitable and comfortable.
Main advantages:
- The versatility of the heating device during operation. You can use a garage wood stove for heating or cooking.
- Relatively inexpensive fuel costs.
- For production, you can use improvised materials.
- Easy oven installation.
- The small size of the heating device makes it versatile when installed in a garage.
- During operation, no additional devices will be required.
- Installing a wood-burning stove for heating a garage does not require an additional source of energy (electricity).
The brick oven will last a very long time Brickwork
In order to build a wood-burning stove, you will need fireclay and refractory bricks. Fireclay powder and refractory clay must be added to the masonry solution. The firebox is installed on the second or third masonry, while the actual masonry, as a rule, is no more than ten. Naturally, you need a chimney device.
It is also laid out from fireclay bricks, and a metal sleeve is installed inside. The chimney must be vented through the roof. When installing a brick oven for a garage, you must not forget that regular changes in humidity in the room after a certain time can worsen the viscosity of the laid mortar, that is, the equipment will not last long.
Potbelly stove design
A potbelly stove is the simplest method of heating. This stove can be easily made from scrap materials. You can use an empty cylinder, sheet steel, or a metal barrel. The most important thing is that the wall thickness is at least 4 mm. If cylinder-shaped products are used, the diameter must be at least 450 mm.
The potbelly stove will become your indispensable assistant in heating the garage This simple design consists of the following elements:
- grate;
- firebox;
- metal door;
- ash pan;
- blower;
- chimney
For the chimney, it is advisable to use a pipe with a metal thickness of at least 4-5 mm and a diameter of at least 130 mm. A combustion chamber is cut out of the blank. A grate is made at the bottom for storing firewood, and a container is installed under it to collect ash.
The chamber is covered from above and a chimney is installed. All that remains is to secure the legs from the metal pipe. To increase the efficiency of heat transfer, small metal “wings” can be welded to the side of the stove. This will increase the area of contact between the hot metal and the air.
For a potbelly stove, it is necessary to prepare a flat surface, which is covered with fire-resistant materials. Nearby wall surfaces must also be protected from possible fire. In addition, no foreign objects should be stored near the stove.
The surface of the oven can reach significant temperatures. We must not forget about the danger of getting burned during contact with it. You also need to be careful when working with an unnecessary gas cylinder. There have been cases of explosion of gas residues during operation of this tank. Professionals advise first filling the cylinder with water so that the liquid can displace the remaining gas.
When using a potbelly stove, you must remember the safety rules Use of waste oil
The design of this stove is a little more complicated than a potbelly stove, but the effectiveness of this unit is undeniable. Every car owner has used oil, and if that’s not enough, you can buy fuel at almost every service station. Unlike a potbelly stove, this stove is made of several sections that are connected by a perforated steel tube.
At the bottom, oil burns, producing little heat, turning into gas. Through the pipe, this gas passes into the upper firebox, simultaneously mixing with a small amount of oxygen. This mixture creates a huge amount of heat when burned.
The lower part, where the oil burns, can be made of sheet metal or a container of any configuration. In order for the fuel combustion process to proceed correctly, it is necessary to make a damper in the container to regulate the volume of oxygen entering the chamber.
At the bottom you need to attach legs made of thick reinforcement, the most important thing is that they are very strong, since the whole structure is very heavy. You need to make a hole at the top and install a perforated pipe into it. As a rule, this pipe is a support for the upper compartment, and it is also exposed to elevated temperatures from burning oil.
Therefore, a structure with fairly thick walls will be required so that it can withstand both temperature and total weight. Most often, the upper compartment is made in the form of a wide and short cylinder. It is necessary to install a smoke exhaust on top; in this case, installing a pipe on the side to remove combustion products is prohibited.
The requirements for this stove are approximately the same as for a potbelly stove: a flat surface, protection of the surrounding area from significant heating. Almost all waste oils can be burned in this heating equipment: diesel fuel, fuel oil, transmission mixtures, kerosene, diesel fuel.
But it is necessary to refrain from experiments with flammable liquids, which are characterized by easy combustion, that is, from burning gasoline or various types of solvents in this stove. A small amount of gasoline can be added to ignite the oil.
A long-burning stove will provide warmth for a long time Long burning stove
The peculiarity of the stove’s operation makes it possible to obtain maximum heat when using firewood. The wood is loaded into the firebox, and a small amount of air is supplied to it. Under these conditions, the fuel does not burn instantly, but gradually smolders, turning into gas.
The gas burns directly in the upper part of the firebox at an elevated temperature, which is what determines the high efficiency of the stove. It is necessary to load firewood into the firebox no more than 2 times a day, so this equipment is more suitable for constant heating of a garage space.
The easiest way to make this heating device is from a metal barrel. A container of approximately 250 liters is optimal for this task. On top you need to make a lid with a smoke exhaust and a hole for the air that is required for the combustion process.
The chimney diameter must be at least 170 mm, and the air supply pipes must be 130 mm. An important element of this stove is the weight that presses down the smoldering fuel. To make it, you need a metal circle slightly narrower than the diameter of the barrel, as well as several pieces of channel material that act as a weighting agent.
You can make such a stove yourself from a gas cylinder or pipe. A hole must also be made in this element for oxygen to enter, after which a pipe with a diameter of 130 mm is welded to the hole. The pipe must be slightly longer than the height of the furnace body. You need to make a hole on the side with a door for loading firewood, and install a grate and a tank for collecting ash at the bottom.
The wood in this stove burns almost completely, leaving a small amount of waste, so a large ash pan is not required. In order to start the stove, you need to lay firewood on top, press it down with a weight, and then cover it with a lid, threading a pipe through the hole to supply oxygen. Taking into account smoldering, the amount of firewood decreases, and the load begins to drop.
The options for various homemade garage stoves are quite varied, and the designs of these heating devices are not very difficult to manufacture. You will need experience working with metal products, a welding machine and available materials. A properly made stove with your own hands can work for a long time and efficiently.
How to make a stove with your own hands:
Car enthusiasts who have a garage at a decent distance from their home always face the problem of heating it in winter. After all, there is no point in having a cold garage. Therefore, everyone tries to invent something for heating. The simplest thing is to turn on an electric heater, but the problem is that it is not able to fully warm up a room such as a garage. In addition, electricity is not a cheap form of energy. There are many options for creating efficient heating in your garage. We bring to your attention some of them. So, let’s make a stove for the garage with our own hands: a review of the 4 best homemade designs.
What are the requirements for garage stoves?
In most cases, the garage is not a very spacious room. This is especially felt when there is a car there. However, the car enthusiast spends quite a lot of time in this confined space. Based on this, the following requirements are imposed on the stove with which it is planned to equip this room:
- Its dimensions should be compact so that it does not interfere with the free passage of people and the entry of cars.
- The stove should operate on solid or liquid fuel, or better yet, on both types.
- The oven must be heated to operating temperature as quickly as possible.
- The oven must maintain the temperature in the garage for a long time.
- The design must be simple and easy to manufacture.
- The cost of materials cannot exceed reasonable limits.
- The stove should be practical, easy to maintain and easy to use in everyday use.
- The heating unit should not burn oxygen too much and release harmful substances into the garage.
- The materials surrounding the stove must be reliably protected from fire.
In our opinion, the following types of homemade stoves meet all these requirements: brick, metal potbelly stove, mining unit, long-burning stove. Let's look at each of them in more detail.
Brick oven for garage
The use of refractory bricks to build a stove in a garage is not very common, since this option is quite labor-intensive. At the same time, a brick oven has a number of advantages and fully complies with the requirements. The dimensions of such a stove are small: it is enough to fold it over an area of 2x2.5 bricks. It runs on regular wood and maintains the temperature for a long time, since brick has excellent heat capacity. The cost of materials is low, and the risk of something igniting from such a furnace is minimal, since the brick is not able to heat up to a very high temperature.
However, this option also has disadvantages. First of all, this is the complexity of the structure. Not everyone knows how to handle bricks and do the laying correctly, not to mention the intricacies of the stove business. Therefore, to lay a brick stove, it is better to hire a stove builder who will take into account all the nuances. Another drawback is that the stove does not heat up to operating temperature very quickly compared to other options.
If you nevertheless decide to build the stove in the garage yourself, then for this purpose you need to use fireclay bricks. It is also recommended to add fireclay powder to the solution. A foundation is made of concrete under the furnace, on which the masonry is made. The length of the stove is 2.5 bricks, and the width is 2 bricks. If you want to make a stove for heating a container of water, then the length needs to be increased to 3.5 bricks. The height of the stove is usually 9 rows of bricks, after which a chimney is made. It can be made entirely of brick, like a shaft passing through the ceiling. Another option is a metal pipe with a diameter of 120 - 150 mm. In this case, you need to take care of proper fire protection of the floors and roof.
Potbelly stove - the simplest device for heating a garage
The simplest and most convenient option for a garage heating device is the well-known potbelly stove. This is a small metal stove. A potbelly stove is made from sheet metal or from an old barrel. Any large diameter pipe will do. In any case, the main criterion in choosing should be the thickness of the metal. It should not be less than 5 mm.
To make a potbelly stove you will need a grinder and a welding machine. To build a stove from sheet metal, it is cut using a grinder according to a template. In order for the size to be optimal for using full-fledged firewood, it is better to take the length of the parts 70 cm and the width 30 cm. A parallelepiped is welded from four elements of the indicated sizes. The back wall is welded into a 30x30 cm square, and in the front wall of the same size an opening for the firebox is cut out, 25x25 cm. For this opening, a door is made with a locking device and hung on hinges, which are secured by welding. Several holes are drilled in the door to create traction.
Legs from a channel or angle of the required length are welded from below, and a round hole with a diameter of 100 mm is cut from above in the rear part. A piece of 110 mm pipe, 15–20 cm long, is welded on top of it. A chimney will be placed on it, which must be well insulated from the ceilings and roof. It can also be placed into a wall, but the angle of rotation should be no more than 30 degrees.
A more effective version of a potbelly stove is obtained if you install an ash pit and an ash pan in it. To do this, a small compartment is made in the lower part of the firebox, which is separated from the firebox by a grate or a homemade plate with slots. This compartment has a separate door through which ash can be removed.
Making a potbelly stove from a barrel or cutting a pipe is even easier. In the case of a barrel, you only need to arrange the door, chimney and legs. If you have a piece of pipe with a diameter of at least 300 mm, then you can make the back of the stove and the door from sheet metal. Everything else is constructed similarly to the previous options. Some craftsmen make good potbelly stoves from old gas cylinders. To cut them, you must first carefully drill a hole, pouring water on the drill. Then drain the condensate from the cylinder and fill it with water. Only after complete rinsing can you begin to cut the balloon with a grinder.
A potbelly stove has all the necessary qualities: it runs on wood or coal, heats up very quickly, is easy to manufacture and maintain, and costs practically nothing if made from waste material. The disadvantage is that it cools quite quickly when the wood burns. Due to the strong heat, the metal stove must be well insulated from the walls of the garage if they are wooden. To increase the efficiency of such a unit, you can weld perpendicular plates 5 cm wide to the surface of the potbelly stove. This will increase the heating area with a slight increase in dimensions.
Homemade waste oil stove
Firewood and coal are not always available to motorists at an affordable price. But used oil can be found in any garage. It’s good if you have friends at the nearest service station. Then there will be no problems with fuel for a homemade stove at all. A unit of this type is quite popular today, even despite its somewhat intricate design. However, anyone who knows how to use a welding machine and a grinder will make such a stove without much difficulty.
The principle of operation of such a unit is based on the fact that gaseous substances, when mixed with air, can burn and release a large amount of heat. The purpose of the furnace is to convert the fuel from a liquid state to a gaseous state and ignite the resulting gas mixture. To accomplish this task, the oven is made of two sections. The waste is poured into the lower one, in which it burns, releasing even more flammable gases. They rise to the second section, which looks like a pipe with holes for air intake. Upon contact with oxygen, they ignite and burn, releasing a colossal amount of heat, incomparable to any other type of furnace.
Such a liquid fuel stove is manufactured as follows. They take sheet iron and weld it into the lower part, which is the fuel tank. It is connected by a pipe, which has many holes with a diameter of 10 mm, to the upper chamber, where the exhaust gases burn out. It, in turn, is connected to the chimney, which must be strictly vertical. There is a hole in the fuel tank into which waste is poured and set on fire. This hole is closed with an adjustable flap. It is used to control the amount of incoming air, and, consequently, the intensity of combustion. If it is possible to make such a stove from a barrel or gas cylinder, then this is even more convenient.
Such a stove can operate on any liquid fuel, excluding light flammable substances such as gasoline, acetone or ether. The best fuels are: diesel oil, transmission oil, petroleum oil, transformer oil, as well as kerosene, diesel fuel, and fuel oil. Due to the high temperature of gas combustion and the presence of an open flame, such a stove must be handled with care. It must be installed rigidly to prevent it from accidentally tipping over, since burning liquid fuel spilled on the floor is unlikely to be quickly extinguished. Under no circumstances should such a stove be left unattended. The unit can be improved by constructing a device for drip feeding of waste into the tank.
Long burning wood stove
This is the most economical, efficient, but at the same time the most complex unit. The principle of its operation is based on the combustion of pyrolysis gases. They have very high combustion energy and produce large amounts of heat. Pyrolysis occurs as a result of slow smoldering of wood with limited access to oxygen. In this case, organic substances break down into solid and gaseous substances. The solids smolder, and the gas rises into the upper chamber and ignites, releasing a large amount of energy.
The advantage of such a furnace is its very high efficiency. One armful of firewood can keep the unit operating for 15 – 20 hours. In addition to firewood, such a stove can use any wood processing waste: sawdust, bark, knots. As a more expensive option: fuel briquettes, pallets and other modern solid fuels.
The main task in the manufacture of a long-burning stove is to create conditions in it that allow pyrolysis to be separated and ignited separately from the wood. Most often, a ready-made 200 liter metal barrel is used for this. The top of the barrel is cut off and a hole is made in it, into which a chimney with a diameter of at least 150 mm will enter. Another hole is cut with a diameter of 100 mm. A pipe will be inserted there for air supply. Then they make a heavy piston. To do this, a circle with a slightly smaller diameter than the barrel is cut out of sheet metal. A hole is cut in it for the air supply pipe and this pipe is welded. A couple of pieces of heavy channel are welded from below to the resulting piston. The piston together with the pipe is inserted into the barrel from above and the entire structure is closed with a lid so that the air pipe comes out into the hole prepared for it. They also make a damper on it to regulate the flow.
At the bottom of the barrel, holes are cut out for firewood supply hatches and an ash pan. They must close tightly to prevent air from entering there, since it must be supplied through a pipe in the piston. The entire structure is installed on a concrete foundation or brickwork.
To fill the stove with firewood, the piston must be lifted by the pipe to the upper position and fixed there. To do this, you can come up with some kind of clamps. The firebox is filled to capacity with firewood. Then the piston is lowered, pressing the wood with it. Ignition is carried out using any flammable liquid, except gasoline. When the wood burns well, the access of oxygen is limited. The released pyrolysis will enter the chamber above the piston and ignite there. They will burn, releasing a lot of heat, although the wood will only smolder.
When choosing an option for installing a stove in the garage, you must be guided by the principle of simplicity and economy. All proposed options meet these criteria and can be successfully accepted by car enthusiasts.
The article was found by the following queries:- stove in the garage
Currently, many car enthusiasts install heating systems in their garages. This is necessary to increase the coziness and comfort of the structure. Agree, it is much more pleasant to repair a personal car in a heated room. Often, a car owner is faced with the task of choosing the optimal type of stove. Wood-burning garage stoves are considered the most common and versatile.
Types of furnaces
The most common wood stove designs:
- Potbelly stove.
- Potbelly stove with water circuit.
- Brick.
- Long burning.
- Convector stove.
Potbelly stove - the most common wood stove, used to heat a garage. The simplicity of the design ensured its great popularity back in the twenties of the twentieth century. Any available material is suitable for its manufacture: old iron barrels, propane cylinders, a simple iron box.
The principle of operation is very simple: when wood burns in the firebox of the unit, the body heats up and releases heat into the room.
Potbelly stove with water circuit is a modification of the potbelly stove. The main difference is the presence of a water circuit. It consists of a pipeline system, shut-off valves, expansion tank, heat exchanger, pump, radiators.
The principle of operation is this - the water in the heat exchanger is heated and flows through the piping system into the radiators. As a result of heat exchange, heat enters the room. Using a pump, cooled water from the radiator is pumped into the heat exchanger for subsequent heating.
Brick oven- the most efficient in terms of heating the room. Thanks to its design and the building material used, it has high efficiency. Such a stove heats up quickly when fired with wood, and retains heat for a long time. The principle of operation is the same as that of a potbelly stove.
A convection oven is also a modification of a potbelly stove. Its design is distinguished by the presence of a forced convection system. It consists of a fan and a collector.
Thanks to this system, the efficiency of a converter furnace is higher than that of a potbelly stove.
The operating principle is similar to that of a potbelly stove. The only difference is that the fan forcibly displaces heated air from the collector into the room.
Long burning stove- This is also a modification of the potbelly stove. Its design uses the top combustion effect. Due to this, this design has high efficiency. Operating principle: combustion in the furnace of the unit occurs under load, due to this, the fire zone has a small area. This ensures long-term combustion of solid fuel.
Advantages and disadvantages
Like any heating device, a wood stove has its advantages and disadvantages.
Let's look at some of the benefits:
- Relatively low price of fuel.
- The versatility of the device during operation. You can use the heater to heat the room, cook and heat food.
- Installation and installation of a garage stove is very simple and does not require large expenses.
- For the manufacture of the unit, scrap materials can be used.
- During operation, the use of additional installations and devices is not required.
- The small overall dimensions of the unit make it universal for use in garages.
- The operation of such a device does not require the use of an additional type of energy (electricity).
The disadvantages of this design include:
- Such furnaces have a high heat output, as a result of which they heat up quickly and cool down quickly.
- To maintain a high temperature in the oven, it is necessary to periodically add firewood.
- Constant monitoring of the heating process is necessary to ensure safety.
Peculiarities
For the furnace to operate efficiently, its design must have certain qualities. Since the garage room is small, the stove should, first of all, be compact. Operating efficiency for a heating device is also important. In addition, the cost of manufacturing the unit should be minimal.
It is necessary to provide for the possibility of firing different types of fuel. This will make the unit cost-effective. By making a stove with your own hands, you can make it as convenient to use as possible. Taking into account all your needs, you will create a unique and inimitable heating device.
First you need to choose the material from which you will make the wood-burning stove. This is where your skills in working with brick or metal will come into play. But in both cases, it must be remembered that the heating device should not reduce the amount of oxygen in the room. It must release heat for as long as possible to warm the room.
The basic rule when operating the stove is the absence of release of harmful substances.
When choosing the design of a heating device, remember that it should not be a fire hazard.
DIY making
The most suitable material for making a potbelly stove is propane cylinders and thick-walled pipe. Old metal barrels will also work. All options are possible. The main condition is that the wall thickness must be at least 2 mm and maximum 5 mm. If you do everything according to the drawings, then such a stove will serve for a long time and efficiently.
Which stove to make - vertical or horizontal - everyone decides for himself. It is more convenient to burn a horizontal stove with wood. But the vertical one is easy to use and takes up less space.
To make a vertical potbelly stove, we divide the pipe or cylinder into two unequal compartments. We place the smaller one at the bottom. Ash will collect here. At the top there is a larger compartment for storing firewood.
- Cut rectangular holes in both parts. We don’t throw away the resulting rectangles; we use them as doors in the future.
- We weld grate bars to most of them. This can be reinforcement or any metal rods of the required size, with a diameter of 12-16 mm. The gap between the grates is 20 mm.
- We mount and weld the bottom.
- We make a hole at the top of the cylinder for the chimney. We make a pipe from a sheet of metal and weld it to the hole at the top of the cylinder. It is better to make the pipe for standard chimneys, so that there are no problems with its installation later.
- We weld hinges to the cut out doors and install them on the stove. The unit is ready.
To make a horizontal potbelly stove, you need to weld an ash box on the bottom. It can be made from sheet steel. We make holes in the bottom of the stove so that the ash spills into the ash drawer.
At the top of the heating device (just like on a vertical stove) we make a pipe for the chimney. We weld the hinges onto the door and install it from the end of the product. The oven is ready for use.
The design of the convector stove is a regular potbelly stove without a long-burning mode, but with forced airflow for uniform heat distribution in the garage. The unit is a potbelly stove with a built-in mini-fan in the back. It pumps air through guide pipes. These can be hollow metal pipes, a profile or a sheet steel box.
There the air is heated and blown forward. The garage space is heated quickly and efficiently. The stove is ready to heat the room.
Many people believe that the best heating device for a garage is a long-burning stove. Its design is based on a vertical potbelly stove. The main differences are the lateral location of the chimney in the upper part and the presence of a removable top cover with a piston. We cut a hole in the top cover and insert the piston. It puts pressure on the wood inside the stove, providing “top combustion.”
Setting up a brick oven in the garage is very simple. It is necessary to have an orderly masonry scheme and have skills in working with bricks. Be sure to strictly follow the ordering scheme. For masonry, fireclay mortar or clay with the addition of cement and sand is used.
Before installing a brick wall, it is necessary to make a foundation 200 mm high. The combustion chamber is made of refractory bricks. The door and the blower are located on the front wall. The grille is placed inside the device on brick ledges.
To make a stove you need 290-300 bricks. The masonry is laid out on fireclay mortar. Gaps are left between the bricks. This is necessary for thermal expansion. The formation of cracks on the body of the heating device due to temperature differences will be minimized.
In order for the stove to last a long time, the brick must be well fired and without cracks. If it is necessary to increase the height of the heating device, this can be done by repeating the rows.
To make a furnace with a water circuit, you first need to build a heat exchanger. Various materials can be used: steel sheets or steel pipes. You will also need skills in working with metal and plumbing.
A private garage is a specific room and is usually very cold in winter. Such a microclimate is completely useless for either a person or a car. At the same time, the use of standard electric heaters often turns out to be too expensive and ineffective.
All that remains is to make a stove for the garage with your own hands, choosing one of the suitable options. We offer for consideration four methods of arranging stove heating, each of which has its own characteristics in creation and operation.
Visual diagrams and video instructions will help you decide on the design of the furnace, assemble and connect the unit yourself.
A major garage with insulation is not available to every car owner. Most often, the vehicle owner has a metal structure at his disposal, devoid of any insulation. Any thermal energy leaves such a structure almost instantly.
When solving the problem of heating a garage space, you should not estimate its heat requirement based on similar experience with a residential building. And it’s not just the lack of thermal insulation.
There is the so-called square-cube law, which states that when the dimensions of a geometric body decrease, the ratio of the surface area of this body to its volume increases.
For normal storage of a car in a garage, the temperature inside the box should not fall below +5º and rise above +18º during the presence of the owners and repair work. The requirements are regulated by SP 113.13330.2012
This affects the size of the heat loss of the object, so to heat one cubic meter of a small room, for example, a garage, more heat is needed than to heat a large house.
If for a two-story building a heating device with a power of 10 kW may be sufficient, then for a much smaller garage you will need a unit with a productivity of about 2-2.5 kW of thermal energy.
To maintain a very modest operating temperature of 16°C, a 1.8 kW stove is sufficient. If you only need to maintain the optimal temperature for storing a car in a parking lot - 8°C - a 1.2 kW unit is suitable.
It turns out that fuel consumption for heating a unit volume of garage space can be twice as high as that for a residential building.
To thoroughly warm up the entire garage, its walls and floor, you will need even more thermal energy, i.e. an even more powerful heater. But even with insulation, heat will leave the room too quickly. Therefore, it is recommended to heat not the entire garage, but only the so-called workspace.
Using insulation: pros and cons
Economy-class garages are almost never insulated on the outside for a very simple reason - it is too expensive for a room that is not constantly used. Yes, this is not always possible, for example, in garage cooperatives, buildings are placed very close to each other, the gap does not allow installation of insulation.
To insulate a garage, you can use materials such as fiberboard, which extinguish when caught on fire. The use of plastic in such a room is unacceptable
But the internal thermal insulation of a garage can also be problematic. When installing insulation material directly on metal walls, a so-called dew point occurs at the point of their contact, i.e. place where condensation accumulates. Almost always, when in contact with moisture, insulation becomes unusable quite quickly.
And for the structure itself, such a situation can be disastrous. Insulation can be installed in a metal garage, but it is better to install a suitable material at some distance from the wall, about 20-50 mm.
You should retreat 50-70 mm from the floor. It is best to use washers as a profile to avoid creating closed contours under the coating.
With this installation option, condensation will also appear, but thanks to air circulation under the insulation layer, the moisture will gradually evaporate without causing any noticeable harm to the structure.
However, for a garage that is constantly heated, this option is not suitable, since the indoor humidity will be excessively high most of the time. This will put both the health of people and the condition of the vehicle at risk.
When insulating a metal structure, it is necessary to leave a ventilation gap between it and the insulating material for regular drainage of condensate
As a material for such “ventilated” insulation, it is recommended to use slabs, for example, fiberboard, chipboard, that is, wood materials that self-extinguish upon fire. Recommended thickness is about 5 mm.
Flat ondulin or its analogues are perfect. These materials have the ability to reflect infrared radiation, which provides effective heating.
But plastic, even with attenuation properties, is strictly not recommended to be placed in the garage. When ignited, such materials emit toxic fumes, which can cause poisoning to people who escaped the fire. It is also prohibited to use slabs containing asbestos as insulation.
When insulating a cold brick garage, it is recommended to first plaster the walls with vermiculite to protect them from moisture. The walls of a metal garage should be painted in two layers, having previously primed the base.
The walls of an insulated garage must be treated with a water-repellent compound to protect the building from the destructive effects of condensation
Overview of possible options
For the garage, the following options for homemade stoves are most often used:
- brick wood stove;
- potbelly stove;
- long burning stove;
- furnace in progress.
Each of these DIY garage oven options has certain advantages and disadvantages. Some units can be combined to expand your garage heating options and make this process more convenient and profitable.
In the construction of a small stove for the garage, you can use virtually waste tools and materials, these are:
