Garage stoves: economical heat from improvised materials
Garage stoves: economical heat from improvised materials
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 stoves for the garage. The structure should be well heated, evenly warm up the air and be safe at the same time.
Spent gas cylinder is the most commonly used material for making a furnace in the garage
What should be the oven in the garage: power requirements of the device
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 heating devices is ineffective and results in a round penny in the form of electricity bills. It is quite simple to solve the problem – you need to build an oven in the garage with your own hands, choosing the best option.
An antique oven will look great in any garage
The problem of garage heating is based on two points:
- lack of effective thermal insulation;
- the square-cube law, which implies the ratio of the dimensions of the surface of the body to its volume.
The mentioned law is reflected in the form of heat loss. To heat one cubic meter of a room with a small area, much more heat is required than when heating a spacious structure. For example, a 10 kW device is enough to heat a two-storey 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, a 2 kW unit can be installed, and for a temperature regime of 8 ° C provided for storing the car, a 1.2 kW unit is sufficient. 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 efficiency of placement 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 stay in a comfortable temperature zone, and the heat consumption will be significantly reduced. The so-called heat cap is formed due to natural convection: a strong flow of warm air rises up, where it collides with a cold dense layer.
The appearance of a garage oven is not as important as its energy efficiency, but a beautiful design will not be superfluous
Useful advice! According to the rules (regarding parking) regulated by the document SP 113.13330.2012, the optimal temperature for storing a car should be at least 5 ° C, and during repair work – 18 ° C.
Thanks to the physical process of convection, which consists in the propagation of warm air flows, efficient heating of almost the entire garage is provided. You can get such a result even with the help of a homemade garage oven with a small capacity.
An important role in the process of heating and heat preservation is played by the insulation system. One of the tricks used by the builders of garage cooperatives is the dense location of neighboring structures, which allows you to preserve heat as much as possible. In individual buildings, various available materials, for example, fiberboard, can be used for external insulation.
Insulation of a metal garage inside can be problematic, since a dew point appears at the point of contact of materials, where condensate accumulates. As a result, this can lead to rapid wear of both the main material and the insulation. Therefore, it is necessary to maintain an air cushion between the main and additional wall of 30-50 mm, retreating from the floor by about 60 mm.
A pipe garage oven is the cheapest option
Types of stoves for the garage: choosing the optimal option
In the garage, it is allowed to install a variety of heating systems that run on various types of fuel: liquid, solid, electric or gas. The main conditions are that 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 garage heating, various units are used, which differ in the principle of operation, type of fuel and features of operation.
Stoves for a garage with wood for long-term gorenje. The principle of operation of such devices is the converter combustion of fuel. The unit requires professional installation, but experienced craftsmen can make it themselves. Firewood, pellets, peat, coal and other types of 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. It belongs to the category of expensive devices.
Bourgeois for the garage. A compact, convenient and affordable version of the furnace, which is easy to build yourself using a basic drawing. The main drawback of the bourgeoisie is the increased threat of fire.
Furnaces for a garage on working out are the most economical option, operating on engine oil, which has already worked out its life in the engine.
The choice of garage stoves available on the market is very wide
A brick oven for a garage allows you to get soft heat for a long time, but under the condition of 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 structures in half a brick. Metal reflects poorly, 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.
A garage oven with long-burning wood: types and principle of operation Gorenje
Any variant of garage stoves has its pros and cons, and at the same time each of them can be made with your own hands. To have an idea of the process of creating the unit and calculate your strength and resources, it is worth getting acquainted with each of the types of devices in more detail.
Burzhuika is a compact, convenient and affordable option for a garage oven
The popularity of stoves for a garage of long-term gorenje lies in their economy, 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 gorenje is due to poor oxygen access. Thus, firewood does not burn instantly, but gradually smoulders, releasing combustible gas.
Furnaces for a garage of long-term gorenje can be different in their design features, a popular variety is Bubafonya. The name of the unit came 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.Gorenje If you try, the Bubaphone 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.
Bulerian is also a popular model of a long–burning furnace, its design is very unusual. Gorenje is a very popular model. The device is widely used not only for office, but also for residential premises. This is a kind of modern hybrid of a classic bourgeois stove and a long-burning stove.Gorenje The unit operates due to forced convection. There are several curved pipes leading to the furnace from below and from above. Cold air enters through the lower ones, which instantly heats up in the furnace and comes out hot from above.

A long-gorenje oven for a garage with your own hands
Despite the relatively complex design, a long-burning furnace can be made independently.Gorenje Such a model will have one, but significant drawback: to rake out the ash, you will have to turn a rather weighty body upside down. To build the unit, you will need a metal cylinder, a welding machine. You can also take a square container as a basis, but under the condition of normal firewood smouldering. The manufacturing process itself in this case will take several hours.
Most often, a thick-walled metal barrel with a capacity of about 200 liters is used for the production of a long-burning furnace .Gorenje From above, fasteners are made under the cover with a chimney, and also a small hole is made necessary for the access of oxygen, which is needed for the combustion process.Gorenje The diameter of the chimney is approximately 15 cm, and the duct is 10 cm. Often the chimney is removed from the side, and a place is left on top for air to enter.
Useful advice! For a wood-burning stove in the garage, you need to purchase dry fuel. It is necessary to choose such types of wood that emit a minimum amount of resin during the burning process.Gorenje
An important detail of a wood–burning stove for a garage of long gorenje is a load to provide a press for smoldering firewood. It can be made from a metal circle, the diameter of which should be several millimeters smaller than the size of the furnace chamber, and two segments of channels acting as a weighting agent.In the weighting circle, it is necessary to make an air duct and weld a pipe with a section of 10 cm to it . Its length must exceed the height of the stove body.
Through the lower openings, the air enters cold, and through the upper ones it already comes out hot
A hole with a door for loading firewood into a garage stove is made with their own hands on the side, and a grate and a container for ash are installed at the bottom. The final touch is the welding of the legs at the bottom of the finished oven.
Oven-stove for garage: the principle of operation and features of manufacture
The usual bourgeois stove, popular in the 20s of the last century, is considered the most popular option for a garage stove on firewood 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 spent gas cylinder will be appropriate here. For successful production, the material must meet the following requirements:
- metal thickness – not less than 5 mm;
- the capacity of the cylindrical shape in cross-section should exceed 30 cm.
The composition of the classic bourgeoisie includes the following elements:
- housing with grille;
- loading door;
- ashtray;
- the chimney is lateral or vertical.
For the manufacture of the chimney, a 3 mm thick metal pipe with a cross section of at least 12 cm is used. The furnace chamber is cut from the selected workpiece. The fuel grate is installed at the bottom, and under it is a 3 mm thick metal ash collection box. The chamber is closed from above and the chimney is removed. The legs for the stove are made of metal corners.
For the manufacture of a bourgeois in the garage, a spent gas cylinder is suitable
Before making a bourgeois in the garage, it is necessary to determine its shape, which depends on the base material. It can be round or square. It is also important to think about the safety rules. Install the stove on a flat and solid base made of fire-resistant materials. The walls also need to be protected from sunburn. There should be no foreign objects near the bourgeoisie.
It is important to take into account that the metal surface of the bourgeoisie will heat up very much 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 bourgeois in the garage with your own hands
The most popular option for a garage stove with your own hands is a metal stove. In order to produce a vertical unit, the workpiece is conditionally divided into two parts. The smaller one will be located at the bottom and serve as a place to collect ash, and the upper part (base) will be a furnace, and firewood will be planted in it.
Useful 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. It can be completely displaced by filling the cylinder with water. There are cases when gas residues in the process of sawing the cylinder provoked an explosion.
The diagram for the manufacture of a vertical bourgeoisie in the garage shows all the necessary dimensions
As an illustrative example, let’s consider the order of work on the manufacture of a garage furnace from a gas cylinder:
According to the same principle, a bourgeois stove is made from a pipe in the garage. 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 furnace 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. A box for collecting ash is placed in a horizontal bourgeoisie from 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 collection for ash are obtained.
The oven in the garage must be installed according to fire safety standards
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 gain stability. 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 the garage from two barrels. A metal stove, unlike its cast-iron predecessor, heats up much faster and it is almost impossible to be near it. To solve this problem, you can use 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 one is an additional frame. The space between the walls can be filled with sand or pebbles.
Such a stove will heat up much longer, but at the same time it will cool down much slower. Therefore, the necessary temperature will be maintained in the garage for much longer, and staying in it will be more comfortable.
Useful advice! Small wings welded on the sides of the stove from the pipe will help to increase the efficiency of heating the stove. These details will increase the area of contact of the heated metal with the air, which will help to warm up the room faster.
The floor and the adjacent walls near the furnace must be made of non-combustible material
A brick garage oven with your own hands
Homemade brick stoves are also used to heat the garage, although much less often. Such a design radiates heat for a long time, but it will take a lot of time to warm it up. This unit is suitable for those owners who spend a long time in the garage and are there every day. In this case, you can simply keep the fire in the furnace by throwing firewood.
To arrange a small brick oven in the garage with a hob, you will need:
- ceramic refractory brick – 290 pcs.;
- door for the furnace chamber 250X200 mm – 1 pc.;
- grate for grates 250X250 mm – 1 piece.;
- the door for the blower 120X120 mm – 1 pc.;
- gate valve 120X120 mm – 1 pc.;
- cast iron plate 70X30 cm.
For bricklaying, it is necessary to prepare a clay mortar. The thickness of the seams should be from 5 to 15 mm. Before installing the oven in the garage, you need to take care of the preparation of the foundation. Its horizontal dimensions should be approximately 20 cm wider than the device itself.
For the furnace, it is necessary to carry out a lining that provides for laying fireclay bricks on a similar solution. Under the casting of the furnace, the bricks are undermined, and under the grates, the stove and the doors, the base should be wider than the casting dimensions. In order to provide thermal insulation, an asbestos cord is used, and strips of mineral wool are also acceptable, which can withstand temperatures up to 1200 ° C.
The laying of the furnace should be made of fireclay bricks on a similar solution
The brickwork, carried out according to the established scheme, on average consists of 15 rows. Approximately in the 6th of them, a valve is installed that allows switching 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 not to have to correct mistakes later, it is better to carry out pre-laying without mortar.
Economical and energy-efficient furnaces for the garage on the development
The spent oil furnace is considered the most economical, since it eliminates additional fuel costs. If the materials are calculated correctly and the manufacturing instructions are clearly followed, then it will not smoke and excessively pollute the air. The operation of such furnaces on transmission, machine or transformer oil is provided. A diesel furnace for a garage operates on the same principle.
Structurally, the unit consists of two containers that are interconnected by a perforated pipe with many holes. If a decision is made in favor of installing a furnace in the garage for testing, then it is necessary that it meets such requirements:
- maximum weight – 30 kg;
- capacity – up to 12 liters;
- standard size – 70x50x30 cm;
- average fuel consumption – 1 l/hour;
- the diameter of the exhaust pipe is 100 mm.
The wood-fired garage oven from two gas cylinders is very economical and easy to maintain
It is quite simple to build such a structure. You will not need injectors and droppers to create it, so you do not need special knowledge, skills or experience to make it.
Useful advice! Before you build a stove for working out, it is advisable to pre-negotiate with the owners of neighboring garages about collecting used oil. The container must be made of metal with a thickness of at least 3 mm.
The following materials will be required directly for the manufacture of the furnace:
- steel pipe;
- two metal containers;
- steel corner.
The container can serve as the housing of an old unusable refrigerator compressor or a gas cylinder. The furnace for the garage for testing should be made of a material with a thickness of at least 4 mm, since it is supposed to be heated to 900 ° C, so the thin metal will simply burn out.
The sequence of manufacturing the stove in the garage, functioning on the development
The furnace for a garage on working out is advantageous in the presence of large stocks of it
The process of creating this type of stove in the garage with your own hands includes the following steps:
Painting will give a presentable look to the garage oven. For this purpose, a mixture of silicate glue, whitened chalk and aluminum powder is used.
Disadvantages of a garage furnace 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 paper into the fuel tank for kindling. Then approximately 1 liter of waste oil is poured. The paper is set on fire and wait a couple of minutes until the oil boils. When the oil starts to burn slowly, it must be added in an amount of 3-4 liters as needed.
Despite the many advantages of this type of furnaces for the garage, it is necessary to mention their disadvantages, in particular:
- a very long chimney, which should be at least 4 meters high;
- it is required that the chimney device be strictly vertical, without bends and horizontal sections;
- the oil tanks and the chimney must be cleaned regularly – about once a week.
Useful advice! To avoid the inconvenience associated with frequent cleaning of the tank and chimney, a design with removable parts will help.
The oil consumption in the furnace during working is regulated by the air supply flap and is 0.3 — 1 liters per hour.
It is necessary to approach the process of creating a heating system in the garage responsibly, so that such structures as a boiler on working out, a brick oven, a bourgeois stove with their own hands are profitable and bring maximum heat. It should be noted that economical options need to be carefully cared for, and brick structures require a certain amount of time for kindling. To create a metal furnace for long-term gorenje will require certain skills and knowledge. At the same time, any of the options considered, under the conditions of proper construction and in compliance with the rules of operation, will make the garage warm and comfortable.
