We make an oven for a garage with our own hands: an overview of the 4 best self-made structures

Motorists who have a garage at a decent distance from home, always face the problem of heating it in the winter. After all, there is no point in the cold garage. Therefore, everyone tries to invent something for heating. The simplest thing is to turn on the electric heater, but the problem is that it can not fully warm up a room like a garage. In addition, electricity is not a cheap type of energy. There are many options for creating efficient heating in the garage. We offer to your attention some of them. So, we make the oven for the garage with our own hands: an overview of the 4 best homemade designs.

What are the requirements for

garage stoves? In most cases, the garage is not a very spacious room. Especially it is felt when there is a car. Nevertheless, the motorist spends a lot of time in this enclosed space. Proceeding from this, the following requirements are imposed on the furnace, which 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 entrance of the car.
• The furnace must work on solid or liquid fuel, and preferably on both types.
• The oven should be heated to the operating temperature as soon as possible.
• The temperature in the garage should be kept long.
• The design must be simple and easy to manufacture.
• The cost of materials can not exceed reasonable limits.
• The oven should be practical, convenient for maintenance and everyday use.
• The heating unit must not burn oxygen too much and release harmful substances into the garage.
• The material surrounding the stove must be protected against fire.

All these requirements, in our opinion, correspond to the following types of homemade ovens: a brick, a metal burzhuyka, a unit for working, a long-burning furnace. Let's consider each of them in more detail.

Brick oven for the garage

The use of refractory brick for the construction of the stove in the garage is not very common, because this option is quite laborious. At the same time, the brick oven has a number of advantages and fully meets the requirements. The dimensions of this stove are small: it is enough to lay it down on an area of ​​2X2.5 bricks. It works on ordinary wood, and the temperature maintains for a long time, since the brick has an excellent heat capacity. The cost of materials is low, and the risk of ignition of anything from such a furnace is minimal, since the brick is not able to heat up to a very high temperature.

At the same time, this variant has its disadvantages. First of all, this is the complexity of the structure. Not everyone knows how to handle a brick and do the right clutch, not to mention the intricacies of stove business. Therefore, for laying a brick stove, it is better to hire a stove-maker, which will provide for all the nuances. Another disadvantage is that the furnace is not heated too quickly to operating temperature in comparison with other options.

If you still decide to independently fold the furnace in the garage, then for this purpose you need to use fireclay bricks. The solution is also recommended to add chamotte powder. Under the stove make a foundation of concrete, on which the masonry is made. The length of the furnace is 2.5 bricks, and the width is 2 bricks. If you want to make a plate to heat a container with water, then the length should be increased to 3.5 bricks. The height of the stove is usually 9 rows of bricks, after which they make a chimney. It can be made entirely of brick by the type of shaft passing through the overlap. Another option is a metal pipe with a diameter of 120 - 150 mm. In this case, you need to take care of competent fire protection of floors and roofing.

Burzhuyka - the simplest device for heating the garage

The most simple and convenient in the manufacture of a version of the heating device for the garage is the well-known burzhuyka. This is a small metal oven. Make a burzhuyk from sheet metal or from an old barrel. Any large diameter pipe is also suitable. In any case, the main criterion in the choice should be the thickness of the metal. It should not be less than 5 mm.

For the manufacture of burzhuyki need a Bulgarian and a welding machine. For the construction of a stove from sheet metal, it is cut by a Bulgarian according to the template. That the size was optimum for use of high-grade fire wood, it is better to take length of details 70 sm, and width of 30 see. From four elements of the specified sizes weld a parallelepiped. The back wall is brewed with a square of 30x30 cm, and in the front wall of the same size an opening for a firebox 25x25 cm is cut out. For this, the door is made with a locking device, and hung on hinges that are fixed by welding. In the door, several holes are drilled to create traction.

Bottom welded legs from the channel or corner of the required length, and a round hole with a diameter of 100 mm is cut from the top in the rear part. On top of it, a section of 110 mm long pipe 15 - 20 cm long is welded. A chimney will be put on it, which must be well insulated from the ceilings and roofing. It is possible to bring it to the wall, but the angle of rotation should be no more than 30 degrees.

A more efficient version of a burzhuyka is obtained if you place an ash-pit and an ash-pan in it. To do this, a small compartment is made in the lower part of the furnace, which is separated from the furnace by a grate or a homemade plate with slots. In this compartment a separate door is provided, through which it will be possible to remove the ash.

Making a barrel from a barrel or trimming a pipe is even easier. In the case of a barrel, you only need to arrange a door, a chimney and legs. If you have a piece of pipe, a diameter of at least 300 mm, then you can make a sheet metal back of the stove and the door. All the rest is built in the same way as the previous versions. Some craftsmen make good burzhujki from old gas cylinders. To cut them, you must first drill a hole carefully, watering the drill with water. Then drain the condensate from the container and fill it with water. Only after a full lavage can you begin to cut the bulb with a bulgarian.

The breeze has all the necessary qualities: it works on wood or coal, it heats very quickly, it's easy to manufacture and maintain, it's almost worthless if you make it from a waste material. As a disadvantage, we can name quite a quick cooling when burning firewood. Due to strong heating, the metal stove should be well insulated from the garage walls if they are wooden. To increase the efficiency of such an aggregate, it is possible to weld perpendicular plates 5 cm wide to the turbine surface. This will increase the heating area with a slight increase in dimensions.

Homemade waste oil heater

Not always wood and coal are available for motorists at an affordable price. But the waste oil can be found in any garage. Well if you have friends on the nearest service station. Then there will be no problems with fuel for a homemade stove on the job. The unit of this type is quite popular today, even despite its somewhat intricate design. However, someone who knows how to handle a welding apparatus and a Bulgarian, will make such an oven without much difficulty.

The principle of operation of such an aggregate is based on the fact that gaseous substances, when mixed with air, are capable of burning with the release of a large amount of heat. The task of the furnace is to transfer fuel from the liquid state to gaseous and ignite the resulting gas mixture. To accomplish such a task, the stove is made from two divisions. In the lower fill the work in which it burns, releasing even more combustible gases. They rise to the second section, which looks like a tube with air intake openings. Upon contact with oxygen, they ignite and burn with the release of a colossal amount of heat, incomparable with any other kind of furnaces.

This liquid fuel furnace is manufactured as follows. Take the sheet iron and cook from it the lower part, which is a fuel tank. It is connected by a pipe having a number of holes with a diameter of 10 mm, with an upper chamber where the exhaust gases are burnt out. It in turn connects with the chimney, which must be strictly vertical. In the fuel tank there is an opening into which the casting is poured and ignited. This hole is closed with an adjustable flap. With her help control the amount of incoming air, and, consequently, the intensity of combustion. If it is possible to make such a furnace from a barrel or a gas cylinder, then this is even more convenient.

This furnace is capable of operating on any liquid fuel, excluding light flammable substances, such as gasoline, acetone or ether. Fuel, oil, gear oil, oil, transformer oil, as well as kerosene, diesel fuel, and fuel oil are the most suitable for fuel. Due to the high temperature of gas combustion and the presence of open flames, it is necessary to handle this furnace with care. It must be fixed rigidly to prevent accidental overturning, since burning liquid fuel spilled across the floor is unlikely to be quickly extinguished. In no case should you leave such a stove unattended. The unit can be improved by constructing a device for drip feed into the tank.

Furnace on long burning firewood

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 a large amount of heat. Pyrolysis appears as a result of slow decay of wood with limited access to oxygen. In this case, organic substances decompose into solid and gaseous. The solid smolder, and the gas rises into the upper chamber and flares up, releasing a large amount of energy.

The advantage of such a furnace is its very high efficiency. One armful of firewood is capable of maintaining the unit's operability within 15 to 20 hours. In addition to wood in such a furnace, any woodworking waste can be used: 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 furnace is to create conditions in it that allow the pyrolysis to separate and ignite them separately from firewood. Most often, they take a 200 liter metal barrel ready for this. The top of the barrel is cut and made into it a hole where a chimney with a diameter of at least 150 mm will enter. Another hole is cut with a diameter of 100 mm. There will be inserted a pipe for air intake. Then make a heavy piston. For this purpose, a circle of a slightly smaller diameter is cut from the sheet metal than the barrel. In it, cut a hole under the air supply pipe and weld this pipe. From the bottom to the resulting piston, a couple of pieces of a heavy channel are welded. The piston together with the pipe is inserted from above into the barrel and the entire structure is covered with a lid so that the air tube exits into the hole prepared for it. It also makes a damper to control the flow.

Bottom barrels cut openings for the hatches of firewood and ash pan. They must be closed tightly to prevent air from entering there, since it must be fed through a pipe in the piston. Install the entire structure on a concrete foundation or brickwork.

For refueling the stove with wood, the piston must be lifted by the pipe to the upper position and locked there. To do this, you can think of some fixatives. The firewood is put into the firebox "under the string."Then the piston is lowered, pressing firewood. Produce ignition using any combustible liquid, except gasoline. When the firewood is inflamed well, the access of oxygen is limited. The released pyrolysis will enter the chamber above the piston and ignite there. They will burn, giving off a lot of heat, although the wood will only smolder.

When choosing a furnace option in a garage, it is necessary to follow the principle of simplicity and economy. All proposed options meet these criteria and can be successfully accepted by motorists.
