If you have a garage, then you must have thought about how to make its interior warmer in the winter, in order to be able to repair the car. This issue is especially relevant for residents of Russia. Such a device should require a minimum amount of fuel and be efficient. Some designs are inconvenient in that they require constant monitoring or maintenance, and also have a fairly low efficiency. All this is accompanied by additional difficulties.
The best solution to the problem is a garage oven. This unit can not be called complex, so you can do it yourself. The device will differ in burning time. Recently, solid fuel furnaces and boilers have become quite popular, because the process of their combustion is delayed for a long time. This indicates that heat will be generated almost continuously.
Such equipment can run on different solid fuels, namely:
- firewood;
- corner;
- pellets;
- wood waste;
- filings.
If you make a stove yourself, then heating the garage does not require large expenses. A garage oven has many advantages. It does not require constant fueling, the process is almost automated, in addition, the actual combustion in the furnace is replaced by decay. One fuel tab is able to provide long-term operation from 5 to 20 hours. For such long periods of time, automation is not required.
Such furnaces for a long-burning garage can be converted to work on pressed wood chips and sawdust. The scope of such devices is quite wide. They can be used even in a country house, equipped with a water circuit. The device will combine two types of heating - water and ordinary stove.
Some observations
If we compare such a furnace with a boiler, it can be noted that the first device will ensure uniform distribution of heat in the rooms and will guarantee efficient heating by heating the case. A disadvantage of the furnace may be that the termination of the combustion process is accompanied by cooling of the radiators. But the furnace itself will emit heat for a long time, so it, together with the water circuit, is more preferable for heating than a solid fuel boiler.
If we compare a conventional furnace with one that has a water circuit, the latter has a coil. Sometimes it is installed in the furnace, however, this option cannot be called the safest for the organization of heating. Sometimes the coolant boils, which provokes the destruction of the coil. A reasonable solution would be to install this part of the device in the chimney cap.
This option is suitable for efficient heating, as the efficiency is increased. The organization of heating is best done at the time of designing the garage. So you can create a model of the furnace, the design features of which will correspond to the layout and area of ββthe room.
Preparation of materials and tools
Before you begin to make a furnace for a garage, you must be prepared. First you need to choose a place where the work will be carried out, because they are accompanied by the formation of dirt. You can work in the workshop or in the yard under a canopy. There should be sources of electricity nearby if you plan to use electric welding. You will need a 200-liter barrel, but its volume and size can not be called fundamental. Even a small gas cylinder can form the basis. In this case, it is better to use a capacity of 27 liters. If you reduce this figure, the stove will turn out to be low-power, and it will not be enough to heat even a small room.
A garage oven cannot be manufactured without the following materials:
- steel pipe;
- metal channel;
- red brick;
- sheet steel;
- reflector;
- materials for the solution.
Some tools
For metal work you will need a hacksaw. Take care of availability:
You will also need measuring devices, as well as a building level, a plumb line and a tape measure. If you plan to supplement the stove with masonry, you should purchase or find a red brick. It will be needed in an amount of about 50 pieces. The reflector is not a mandatory component. Prepare electrodes for the welding unit. Replace the mortar of cement and sand with a ready-made building mixture.
Assembly technique
If you want to make a furnace for a garage from a cylinder, then at the first stage you must prepare the case. The upper part is cut off from a barrel or cylinder. In this case, you can use a grinder or autogen. Any other cutter will do. These works should be carried out as accurately as possible, because the bottom will be needed in the future.
If there is no barrel or gas bottle available, you can make a furnace from a small section of the pipe, but it should have an impressive diameter. The bottom is welded to this part. For its manufacture, a circle is cut from a piece of sheet steel.
Work with metal
The drawings of the garage stoves, which you can find in the article, should help you with the work. You can make a scheme yourself. At the next stage, it is necessary to cut a circle from a sheet of steel, the diameter of which will be somewhat smaller than the inner diameter of the pipe, barrel or cylinder. In the same circle, another circle is cut for installing the pipe. It is better if its diameter is 10 cm. A piece of a small pipe is welded to the cut steel pancake. The sections of the channel prepared in advance should be welded to the bottom of the bottom. They must be measured so that they pass inside the barrel. They will crush the fuel as it burns through when the pancake goes down.
The length of the pipe that is welded to the pancake should be 20 cm greater than the height of the main element. Now you can proceed with the construction of the cover of the future furnace. At this stage, the cut off part from the barrel is useful. Otherwise, you will have to cut the workpiece from a metal sheet. Holes for a small pipe are cut out in the lid.
In the barrel, which formed the basis of the wood-burning garage oven, do-it-yourself need to cut out the hatch for laying firewood, after which the door is welded to this place. You can purchase or make it yourself. You need to weld a handle to the door. Below is installed another door with smaller dimensions, which will be necessary to remove coal and ash.
Foundation work
Looking at the drawings of the furnaces for the garage, you will certainly understand that there is a foundation in such structures. It should be capital, because during the operation of the device the metal will heat up. The design does not have a large mass, even taking into account the brick lining. However, it is not possible to install a wood-burning stove for a garage on a non-refractory or fragile base. The foundation will be a slab. There is no need to deepen it, because the weight of the furnace is small. You can lay out the plate even in one brick, covering the surface with a solution.
Stove chimney
A wood-burning garage stove, like any other, has a chimney, with which the device will get rid of combustion products. For this, a metal pipe is used, the diameter of which is 15 cm. You should not increase this parameter. The pipe is welded from above or from the side.
The straight part of the chimney must be longer than the diameter of the casing. Although it is possible to bend the chimney, it is not worth bending pipes more than 45Λ. This also applies to the use of many different segments. The chimney should have as few bends as possible before leaving the room.
Development furnace
An oven for a working garage can also be made from a cylinder, which is previously cleaned of the contents. A heat exchanger with an air swirl and a fan can be connected to the casing. As a container for oil, you can use a freon cylinder. The body volume should be about 50 liters, while the wall thickness is 5 mm. The internal section is 100 mm.
There should be a partition between the two cameras. For this, a 4 mm sheet of metal is used. Evaporation will occur from the oil reservoir, and the brake disc can be taken as a basis. Oil will flow through the pipe to the evaporator. Part of the pipeline should be located above the ball valve, for ease of installation, the element can be made flexible. You can stop the fuel supply using a ball valve.
For a swirler, two metal corners should be used, which are welded together. Such stoves for heating the garage are perfectly suited. This is especially true if you have excess used oil. In order for the heated air to circulate around the room, a heat exchanger should be installed. As it is a 100 mm pipe, which is located inside the housing, between the chimney and the burner.
To hold the flame, a metal pad should be welded to the top of the heat exchanger. The workpiece is cut from a 4 mm steel sheet. The duct fan will allow for forced air supply. It can be made automatic with hot melt adhesive. A makeshift garage oven will have a swirl. It is necessary in order to keep the heat better. This element is placed inside the pipe. The design will consist of 2 welded steel corners, the shelves of which are cut and turned in the form of blades.
What stove to make gas
Natural gas burns very quickly, and a lot of heat is released. Brickwork will not be able to immediately perceive and transfer such a stream to the room, because a device of this type has an instant effect. The brick oven acts as a heat accumulator. Metal stoves are suitable for gasification, because their gas efficiency increases.
If you want to gasify an old stove, then the brick structure must satisfy certain conditions. For example, it should not have a large furnace part and massive masonry, so the Russian stove immediately disappears. In addition, the device must be made according to the channel scheme, have a developed smoke exhaust system, like Swedish or Dutch devices.
Gas furnace manufacturing
The gas furnace for the garage will consist of the following elements:
- thermostat protective housing;
- sealed chamber;
- chimney.
The enclosure will protect the contents. It will be possible to stop the supply of gas using a fuse, which may become relevant during attenuation. A wood-based system has no such possibility. The thermostat will be responsible for the thermal properties. The safety of people will depend on the integrity of the camera.
Before the construction of the furnace you will need to build a foundation. Its construction begins with a foundation pit. Its bottom is located below the freezing line of the soil. At the bottom, the width should be slightly larger than the main notch. This approach will eliminate the hassle of the movement of the soil. The bottom is covered with sand, which is watered and compacted well. The next layer will be the battle of brick and stone. The thickness of the layer is 20 cm. Once you have covered the gravel, you can install the formwork, reinforcing cage and fill.
The basis may be a brick and a gas burner. You will need:
- galvanized iron sheet;
- sand;
- clay;
- chimney pipe;
- burner;
- mineral wool for insulation;
- decorative overlays;
- heat resistant steel sheet;
- automatic control unit for the burner.
Before starting work, it is necessary to install a protective wall, which will exclude fire in the bath. To do this, you can use a brick cut in half. It is placed on a sand-clay mortar. For laying the foundation, the brick is immersed in cold water for several seconds, after which it can be laid on the mortar. The bitumen base acts as a waterproofing layer.
The rows are laid out in a checkerboard pattern. In the third row, the blower door should be installed. It is attached to the base with steel strips. In the fourth row there is a well for the grate. Holes will need to be cut in bricks to provide room for thermal expansion of the metal.
In the sixth row, it is necessary to fix the door for the blower. In the seventh row will be installed grate. The next row is the installation of the partition for the chimney. Channel bars for the tank crash into the fourteenth row. To do this, a recess is performed, where after the tank will be inserted.
For the distribution wall from the 15th row, the bricks are laid out in half. From the 15th to the 18th rows, the material is laid out to decrease. The 19th row will be the place where you have to install the door for the release of vapor.
In the 20th and 21st rows you will need to lay strips for the container, which they lay out with bricks. The chimney begins to form from the 23rd row. Its size is selected taking into account the premises. From the street, this part of the furnace must be insulated with mineral wool. The pipe should rise 1 m above the ridge of the roof.
Conclusion
A wood-burning garage oven can be made of brick, sheet metal, a barrel or a gas bottle. You can use the materials that are at your fingertips. For example, for lack of a barrel you can use a brick which remained from the construction of the main house. If you donβt have the money to purchase a finished construction made in a factory, you can easily make a furnace for a long-burning garage, which does not require constant monitoring by a person.
