Homemade heaters for home, summer cottage and garage

Rarely, when building a garage, provides the possibility of heating. Therefore, during operation, the premises have to be heated independently. Agree, buying heating devices for periodic use is sometimes costly and impractical.

Some craftsmen make the unit with their own hands, using inexpensive materials. We invite you to familiarize yourself with the three most popular solutions for the organization of individual heating.

Before you make a homemade heater for a garage, you need to understand the principle of operation of each unit, its structure and study the assembly procedure.

Improving a homemade heater

If a similar design of an oil heater is planned to be used in another place, for example, in a country house, then some changes will have to be made to it. They will only touch the electrical part. The fact is that you are in the garage temporarily, but in the country, in comparison with the garage, you are permanently. Therefore, the requirements for the room temperature will be different.

In order to achieve comfortable heating conditions for the country house, the wiring diagram of the heater must be slightly changed. For this, a relay is introduced into the heating element circuit, which will control the heating of the element, maintain the specified temperature of the coolant. And again, the old electric iron, or rather its bimetallic plate, can play its positive role. In the iron, it served as a regulator of its heating, here its purpose will be the same - to maintain the given oil temperature. In addition to the direct, there will be an additional effect - energy savings. The dependence is direct - the lower the temperature, the less electricity is consumed.

Bimetal Iron Plate

A home-made designed oil heater completely replaces the purchased one, and even surpasses it in some parameters. This is, firstly, the manufacture of the required dimensions. Secondly, tangible savings in material resources

Of no small importance will be the fact that the garage will be slightly cleaned of unnecessary trash (pipes, trimming a corner, profile), from which a useful and necessary thing will be made

The video shows the manufacture of a slightly different model of an oil heater.

Before you make a homemade heater for a garage, you need to understand the principle of operation of each unit, its structure and study the assembly procedure.

Heat gas cannon

When choosing a homemade heater, you should definitely pay attention operational safety indoors and comply with certain requirements.

Infrared heaters use burners with ceramic honeycomb. During the combustion process, the ceramic elements are heated, then the heat is transferred to the ambient air in front of the burner. Then the heated air rises and spreads throughout the garage. The power of this type of heaters up to 6.2 kW, they are much more efficient than electric ones. Disadvantage: substances spent in the process of fuel combustion remain in the garage, therefore compulsory airing.

Catalytic gas heaters have no such disadvantages. The gas combustion process takes place in special cells with a catalyst and almost all combustion products are neutralized. The power of such devices 3.3 kW.

For heating the garage, it is often used heat gas gun. Its main drawback is that the burnt fuel discharge and the warm air stream are not separated, but pass into the room. Such a device can be made independently and so as not to suffocate and not burn out with it. The design can be based on gas burner with a small spray can made in China. First, the gas supply pipe is cut in the middle, then a suitable piece of pipe with a diameter of 80 mm is welded on for lengthening. Next, holes are drilled for air with a diameter of 5 mm and the diameter is increased to 2 mm. burner jet.

Heating cables

Laying a warm floor in a garage is not always advisable, but in one situation such a design will be more than justified. We are talking about starting a car in cold weather - often a lot of problems are associated with this, and the presence of a heating cable will greatly simplify the task. In addition, you can only lay the cable under the car and turn it on only if there are problems with starting the engine.

The machine must first be covered with a cover that will cover it completely - this will allow the concentration of heat energy in one zone. Air will not move into the garage itself, so the level of heat loss is minimized. This technique will allow you to quickly warm up the car, even in severe frost.

Infrared heaters and their features

The operation of infrared heaters is based on the principle of wave radiation, due to which objects and surfaces located in the path of the rays are warmed up. This is the key difference between infrared devices and other types of heaters, which primarily heat the air.

The main element of the considered type of heaters is the radiator. In household devices, the operating temperature of the emitter can reach 600 degrees. In addition to electric infrared heaters, there are also gas devices, but using them in rooms without good ventilation (and most garages fit this definition) is prohibited.

There are the following types of infrared emitters:

Metallic. Low-temperature heating elements made of stainless steel, equipped with aluminum radiating plates, are the simplest and most reliable elements available. When heated and cooled, such devices crackle slightly.

Ceramic. These emitters consist of a ceramic panel that is heated by a metal coil. Such devices are characterized by relatively low efficiency.

Micathermic. The radiator plate of this type is covered with mica and heated to a temperature of 60 degrees. Devices with micathermic emitters are more expensive than the previous two options.

Quartz. The heating element is a tungsten filament, hermetically sealed in a vacuum tube made of quartz glass

Such devices must be handled with care due to their fragility.

Halogen. Such an emitter is structurally similar to a quartz one, but the tube contains an inert gas

The filament heats up to a higher temperature and glows during the heating process.

Carbon fiber. Another representative of lamp emitters.The vacuum quartz tube contains a carbon filament, which provides the highest efficiency compared to halogen and quartz devices. The cost of carbon emitters is the highest in comparison with analogues.

In garages, infrared heaters with aluminum emitters are usually used - they are cheaper, more reliable, and much stronger, which is important when operating the device in a garage. Aluminum heaters usually operate at temperatures no higher than 300 degrees

At this temperature, flammable materials (paper and wood) do not ignite, therefore such heaters comply with fire safety requirements. In favor of such devices is the fact that they do not burn out oxygen, and a person will be able to stay in a heated room for a long time without any problems.

Aluminum heaters usually operate at temperatures no higher than 300 degrees. At this temperature, flammable materials (paper and wood) do not ignite, therefore such heaters comply with fire safety requirements. In favor of such devices is the fact that they do not burn out oxygen, and a person can be without problems in a heated room for a long time.

When choosing a heater with a plate radiator, it is imperative to find out what is the thickness of the anode layer - for normal and long-term operation of the device, this figure should exceed 25 microns. The heating element should be located in a stainless case, which will not rust at high humidity in the room.

Infrared garage heaters have the following advantages:

The possibility of uniform heating of the entire room or the creation of local heating in a specific area;
The ability to warm up any part of the garage, including even the most difficult to access.

Requirements for a garage heater

Since it is assumed that the heating of the room will be carried out in the presence of the owner, it is undesirable for a home-made device to burn oxygen with a heating element, release toxins and spread an unpleasant smell of burning.
Surely I would like the device under construction to not take up much space in a small garage, making it difficult to move around during operation.
It is desirable that the device has a good heating rate and maintains the achieved temperature level for a long time.
The risk of explosion and fire must be excluded.
The cost of materials and components was significantly lower than the price of a factory heater.

Such a cheap, simple and easy-to-manufacture heating means will be a home-made heater, for the implementation of which you will need fiberglass, glue and nichrome wire.

The device and features of convector heaters

Convection is a working principle in which heating occurs due to the different densities of cold and heated air. The cold air from the bottom enters the heater through special holes, heats up, its specific gravity becomes less, and the heated air comes out through the holes located in the upper part of the device.

In heating convectors, everything happens exactly according to this principle - i.e. the air moves naturally, heating up in the interior of the heater. An increase in the intensity of the intake of cold air significantly increases the heat transfer of the convector.

Convection heaters are usually wall-mounted - this allows the unit to draw in air from the bottom and release heat through the top panel. The holes in the upper part of the convector are equipped with special elements that allow you to adjust the direction of movement of the heated air.

There are several types of convectors:

Electrical. They are characterized by simplicity of installation and operation.
Gas.The main distinguishing feature of these devices is their high power. When installing gas heaters, a high-quality chimney must be provided for supplying air and removing combustion products. In small rooms, only devices with a closed combustion chamber can be used.
Water.

Among the advantages of convector heaters it is worth noting:

The low temperature of the device, due to which the likelihood of burns upon contact with it is excluded;
Limiting degree of fire safety of electrical devices;
Simplicity of design and minimal likelihood of breakage.

What should be a gas heater

A high-quality and safe heating device of this type can only be considered if:

the elements responsible for the gas supply are prefabricated;
simple activation / deactivation methods are implemented in its design;
the device has a not too complicated design.

In many cases, gas heaters, among other things, are equipped with chimneys that are responsible for the removal of combustion products. Such additions are not used only when assembling a device of very low power, used to heat small rooms.

What is required to make a heater

In every garage you can find a lot of useful things that at first glance, it would seem, are not of particular value, but in the hands of a skilled owner, they can turn into useful devices or devices. By its design, a home-made heater resembles factory counterparts, where the principle of operation is based on the fact that the heating element, in this case it is a nichrome spiral, is hermetically sealed between the sheets of fiberglass, as a result of which the sheet heats up and heats the surrounding air.

To make a homemade heater you will need:

Nichrome wire heating element

Glass fiber laminate.
Glue Monolith.
Nichrome wire.
Electric wire.
Metal rivets.
Electric drill.
Matches.

Fiberglass laminate will require two sheets, each 50x50 cm in size and no more than 1.5 cm thick. Although the dimensions may be different, the sheets should be the same in thickness and geometric dimensions. A garage heater can be square or rectangular, but the perimeter of its sides should not be more than two meters.

Parts made of fiberglass are necessary to fix the main heating element in our homemade device - a nichrome spiral, which is made from 24 m of wire. Two lengths of electrical wire based on the location of the heater and electrical outlet. Metal rivets can be replaced with bolts and nuts.

For a similar model of a home-made heater, the power of which will be equal to 100 W, nichrome wire is used with a cross section of no more than 0.3 mm.

Homemade gas heater for garage, house, summer cottage

When creating a heater with your own hands, you need to adhere to several recommendations:

The device must have a simple design without complex elements and details.
It is necessary to focus on safety, because devices that block and supply gas are best purchased from the factory, or removed from old cylinders.
When creating a gas heater, you should also take into account its economy.
The heater should not be cumbersome, and the ways to activate it should not be complicated.
The cost of materials for the heater should be no more than a third of the real price of the factory heater from the store counter, otherwise there is no point in making it, it is easier to buy a ready-made one.

As practice shows, the most effective way of heating at home is infrared radiation.

To make such a gas home-made heater for a garage, house, summer cottage with your own hands, you need a minimum of parts and material costs (sheet of tin, metal scissors, riveting machine, rivets, metal fine mesh, a regular household sieve, tsarovy gas canister with a capacity of 0.5 l. and a special burner with a valve).

The first thing to do is fasten the heater to the burner. You need to take a household sieve, lean it against a galvanized sheet and circle it with a marker. Then, perpendicular and parallel, it is necessary to draw rectangular ears to the circle (one of them should be twice as long). With scissors for metal, you need to cut the pattern. It should be as flat as possible.

The second stage of the heater installation includes the fastening of parts to each other. To do this, we take the burner and bolt it to the tin circle. Then, with the help of the ears, which turn in the opposite direction, the strainer is attached. It helps dissipate heat around the sides. It turned out to be part of the design of the heater.

The third step in mounting a homemade heater will be to attach the metal mesh. To do this, you need to cut out an identical circle from the tin again. It is also cut with metal scissors. The ears are bent, and holes are drilled in the plane of the circle (about 10). Then the mesh is taken and attached to the ears of both circles. First you need to fasten the lower part, then the upper one. Fasteners are carried out using a riveter and rivets. As a result of these operations, a mesh cylinder should be obtained.

The final stage is the launch of an infrared homemade gas heater. Although it is not large, it radiates enough heat to heat a garage, a room in a house or a small country house.

Tabletop fan heater manufacturing

This type of device is a heater and a fan all rolled into one. If desired, a homemade fan heater can be used as an impromptu air conditioner.

This type of heater is convenient in that it allows you to adjust the heating temperature and the rotational speed of the cooler.

Selection of the required materials

To create a fan heater, you will need the following materials:

rheostat;
switch;
power connector;
electrical wire;
LED Strip Light;
12 volt computer cooler;
three-ampere power supply for 12 volts;

To fix the heating element, you will also need two ten-centimeter rods of copper wiring with a cross section of 1.5 sq. Mm.

From the tools you need to prepare:

jigsaw;
hammer drill or drill;
soldering iron;
hole saw;
glue for woodwork;
"Moment" or superglue;

Fine-grained sandpaper is also required to clean wood by removing burrs along the edges.

Assembly of body parts

The future heater will be in the shape of a cube. The body of the device is assembled from wooden planks 9 mm thick.

two square blanks measuring 12 * 12 cm;
3 pieces measuring 10.2 * 10.2 cm;
two rectangular blanks 12 * 10.2 cm;
four small rectangles measuring 1 * 1.5 cm.

To make the legs of the structure, 2 pieces of 3 cm long are sawn off from a wooden stick D12 mm.

To simplify your task, make paper patterns, the dimensions of which correspond to the dimensions of the workpieces 12x12 cm. The layout of the holes is applied directly to the patterns. They are applied to each side and drilled through.

In the workpiece 10.2 * 10.2 cm, keeping a distance of 2.5 cm from the edge, make a hole D7 mm. On the second same workpiece, two of the same holes are made, maintaining a distance between them of 2.5 cm.On the third workpiece, 10.2 * 10.2 cm, a through hole D9 cm is made in the center.

Holes D5 mm are made in each of the four rectangular blanks measuring 1 * 1.5 mm.

On the long side of a rectangle measuring 12 * 10.2 cm, stepping back from the edge by 1.2 cm, make two holes D12 mm, maintaining a distance of 7 cm between them.

A square workpiece with a 9 cm drilled hole is installed inside the body. After that, the last rectangular piece is attached, closing the body of the structure. At the final stage, the legs are glued.

Installation of heating elements

A spring stretched between two copper rods will act as a heating element. To determine if a spring is suitable, connect it to a 12-volt power supply and measure with a multimeter.

So, to create a warm flow, it is quite enough if the readings of the multimeter are 2.5 A. With such parameters, with a power supply of 12 W, about 30 V of heat will be generated.

The selected spring is soldered to copper rods, the ends of which are fixed on the workpieces measuring 1x1.5 cm. The assembled structure is glued to the corners of the body. Bare "tails" of an electric cable are soldered to the ends of the rods. After that, a bar equipped with holes is attached.

Having fixed the cooler inside the case, the same manipulations are performed with the rheostat, the switch and the power connector.

If all structural elements are connected correctly, then at the moment the rheostat is turned on, a blue light will light up on the LED strip. At the moment the switch is turned on, the LED strip will take on a red hue, which will create a purple color against the background of the main blue. After that, the heater spring will begin to heat up.

The assembled structure from the outside can only be sanded and treated with wood wax, or varnished in 2-3 layers.

Due to its presentable appearance, such a heater can be safely used not only for heating the garage, but also for arranging living rooms.

Alternative options for economical heating of the garage are described in this article.

What to make a heater out of?

Prepare in advance all the tools needed to assemble a homemade garage heater. Most of the components can be found in the home pantry. The missing parts are sold in hardware stores at a relatively low price. The only special tool is a multimeter. In the future, you will use it to diagnose a homemade heater, but you will not need a multimeter at the stage of assembling the unit.

Multimeter

Heater assembly kit

Glass. You need to prepare a pair of identical rectangular glass pieces. Each rectangle should have an area of about 25 cm2. If desired, it can be increased, but the suggested value is the most optimal.
Scissors. With their help, you will cut the foil.
Sealant.
Soldering iron.
Electric cable with a working plug. In the case of a garage heater, a two-wire cable is used.
Foil.
Epoxy based adhesive.
Cotton swabs, cloth and other cleaning tools.

Stages of assembling a homemade heater

After all materials, tools and fixtures are prepared, you can start assembling a homemade heater:

DIY garage heater

Fiberglass sheets from the inside are cleaned with fine sandpaper.
The markings are made - a line is drawn in the upper and lower parts, stepping back 2 cm. On the right and left sides of the sheet, the indent will be 3 cm. The heating coil will be attached to one sheet, for which it is necessary to make several holes on it along both edges of the sheet. Two more holes must be drilled to secure the supply wires. They are located on the edge where the indent of 3 cm is left.
Before making a heater with your own hands, you need to turn the wire into a spiral by winding it around a nail or a long knitting needle.
Matches, toothpicks or other fastening parts are inserted into the lower and upper holes, which can be easily removed after the end of the work.
The spiral is laid in rows, winding each row behind a match in the hole. A distance of 8-12 mm must be observed between the rows. Every 5-7 cm, the spiral is fixed with paper centimeter strips, on which Monolith glue is pre-applied. When the whole spiral is evenly placed on the panel, the matches can be removed, and these places can be additionally strengthened with paper strips with glue.
Metal rivets are inserted into the side holes, onto which the stripped ends of the electric wire are wound. On the outside of the fiberglass plate, a washer is put on each rivet so that the contact is firmly fixed.
The next step will be to check how the assembled electric heater works with your own hands, for which they connect the product to an ohmmeter and an outlet.
Now you need to glue the second sheet, for which you use epoxy glue. It needs 150 grams. Epoxy is applied between the rows of the spiral and a second panel is applied on top. In order for the gluing to occur qualitatively, a sheet of plywood is laid on top of the second sheet and loaded. The weight of the load must be 40 kg or more, but not less.
The time for complete curing of the epoxy resin is a day. On the second day, you can already use a homemade device. But before that, you need to make a mount on the back wall if you plan to hang it on the wall or legs if it will be located on the floor.

Basic requirements for heaters and safety measures

It doesn't matter at all whether you decide to make a heater with your own hands for a garage or buy it, they all must meet the following requirements:

Safety.
Profitability.
Ease of operation and manufacture.
Heating rate of the room.

Important! You should not make a too complicated device for heating, since there are a lot of ready-made inexpensive factory-made models on sale. It is wiser to create something on your own from scrap materials or broken old devices that need minimal costs for assembly.

When manufacturing a heater, all safety measures must be observed; it is imperative to equip a ventilation system in the room, regardless of the heating method. The presence of a large amount of combustion products and exhaust gases, an insufficient amount of oxygen can seriously affect health. You will also have to take safety measures related to preventing a possible explosion or fire, therefore:

It is recommended to install heaters away from flammable substances.
Refuse to use open spirals, be sure to use protective nets and covers.
Equip your garage with fire extinguishers.
Only use the devices under supervision, never leave them in working order unattended.

Important! A self-made device must have a sufficient power level to quickly heat the room, while at the same time not exerting excessive stress on the wiring. The device must justify all costs associated with its maintenance.

Heater power calculation

To calculate the thermal power required to warm up the garage, you need to use the following formula:

N = V x dT x K, where
N - heater power (kcal / h),
V is the total volume of the room,
dT is the temperature difference in the room and outside,
K is the coefficient of heat loss.

For calculations of heat loss, the following values of the coefficient K are taken:

0.6-0.9 - the garage is high-quality insulated;
1-1.9 - garages have an average quality of insulation;
2-2.9 - the garage has insufficiently effective insulation;
3-3.9 - the garage is not insulated.

To convert kcal / h to W, a simple formula is used:

1 W = 0.86 kcal / h, or
1 kcal / h = 1.163 W.

Heater selection criteria

A garage is a non-residential premises used not only for storing motor vehicles, but also for carrying out its repairs. Accordingly, in addition to the four / two-wheeled "friend", it also contains a considerable amount of all kinds of tools and materials. Most often, it is not possible to provide free access to this room for gas pipes, which means that it can be heated only with the help of heaters operating from the mains.

Thinking about which heater to choose for the garage, it is important, first of all, to determine for yourself the main criteria that it must meet in its work:

compactness is perhaps one of the most important criteria, since there must be enough space to carry out vehicle repairs;
health safety - despite the fact that the garage is not a living space, its owner can often spend a considerable amount of time in it, and the way he breathes air at the same time plays an important role;
ease of operation, installation, etc. - undoubtedly an important criterion, since setting up a heater is not the purpose for which the garage owner visits him;
autonomy.

A little later we will consider the most diverse options for heating devices, but before starting to get acquainted with them, it is important to determine for yourself what functions they will perform. It depends, first of all, on the area of the building, the presence of ventilation in it, etc.

Some say that it is more convenient to work at a not very high room temperature, and if you are one of those who think so, then a not very powerful compact heater model is quite suitable for you. But first things first.

DIY oil heater

Due to their impeccable functionality, characteristics and efficiency, oil heaters have gained great popularity among summer residents. They are safe and compact, and have a high level of efficiency.

The device of a homemade oil heater is very simple: a sealed case with oil (any gas cylinder or other sealed container can do), around which electric tubular heaters are wrapped.

To make an oil heater, you need the following materials and tools:

Hermetic container (radiator from the car, metal or aluminum battery).
Transformer or technical oil.
4 heating elements.
Low power electric motor or pump (up to 2-2.5 kW).
A set of drills, drill, welding machine, electrodes, switches.

The process of installing an oil heater at home follows the following scenario:

Frame installation. The frame needs to be made so that it is transportable and easy to use, it is also worth considering the way it is stored in the warm part of the year. The corners are welded together using a welding machine.
Holes for installation of heating elements. The holes can be made with a grinder or welding, and best of all with an autogenous machine (if it is possible to get it).
Mounting a pump or motor. You can install a motor or pump directly on the heater body or on a frame. It is necessary to ensure that the pump does not touch the heating elements.
Fastening of heating elements. The heating elements are installed in a pre-prepared place using bolted connections.
Tightness. To achieve tightness, all holes must be welded. For more convenient use of the heater and emergency drainage of the liquid, you can mount a cover that would be screwed to the body.
Connecting heating elements. They need to be connected in parallel (this is how the heater will work effectively). You can select the desired temperature using the regulators.
The oil heater is almost ready. It remains to assemble everything on the frame and ground the entire device.

A do-it-yourself oil radiator will be an excellent and effective heater for your home and garden. Its only drawback is dependence on electricity and its high consumption.

Traffic

Run to keep warm

Not sure how to keep warm in the car if the above methods are not suitable for you? Remember the main character from the movie "The Irony of Fate or Enjoy Your Bath"? That shot of him jumping in place and jogging to keep warm. In fact, this is the most effective way to keep warm, but also the easiest. That is why I got to one of the bottom lines of the rating.

You can recommend the following: turn on the music (if there is enough charging in your mobile phone), put on headphones and beat out the rhythm with almost all parts of the body to the groovy melody.

It is also helpful to rub your limbs periodically to keep them from going numb.

If it does not help, then you need to leave the salon. And quickly run around the car for as long as possible. At the same time, you need to breathe slowly and evenly. After warming up, you should not stay outside. Get back in the car. Freeze - go out again.

Thermos seventh place in the rating

A regular thermos, preferably a voluminous one, will help to warm up well in the car. Or rather, not himself, but its contents. Hot tea has a good effect on blood circulation and does not constrict blood vessels, such as coffee. And the best way is to carry just a thermos with a hot thyme drink. This tea will warm you very quickly. As you know, the substances contained in this herb growing in the mountains are very useful for the human body. Since ancient times, frostbitten travelers were warmed with just such tea, giving it to drink.

To keep warm, you can drink a cup of hot tea or coffee.

The British would suggest drinking some grog or mulled wine. But in addition to hot water, then you need to take a bottle of semi-sweet wine with you on the road. Ideally, the wine should be boiled, but on the road, it can simply be mixed with hot water. It will not only help you keep warm in winter, but also cheer you up. But it is better not to get carried away with alcoholic beverages, such as vodka, while sitting in the passenger compartment. They warm only illusory, but in fact the consequences can be disastrous. "Under alcohol" you can safely fall asleep and freeze.

You can also mix it with hot water with linden honey, which can be kept in the glove compartment of your car. A spoonful of honey mixed with hot water will warm you better than any other remedy.

Heating with liquid fuel

Do-it-yourself budget heating of a garage can be done using liquid heating units, including home-made ones. In our reviews, we have already described working furnaces that provide cheap and, in some cases, free heat. For example, if you are changing engine oil, then during the spring and summer you can collect several barrels of finished fuel. A properly assembled oil stove will generate a large amount of heat and will delight you with even combustion without soot and soot.

Good results are given by pyrolysis-type ovens, consisting of several parts, as shown in the figure. A fire is ignited in the oil container, as a result of which oil vapors and pyrolysis products begin to form. They are burned in a vertical orifice tube, generating a lot of heat. By adjusting the oxygen supply, you can adjust the intensity of combustion.

When using any oven, it is better to set aside a separate corner for it. You also need to think about a reliable base and lining of adjacent walls with non-combustible materials.

Using a plasma oven for heating a garage, you can achieve maximum heat output and minimum fuel consumption. The oil here disintegrates into its constituent parts in a hot bowl, after which it burns with the formation of a bluish-white flame, similar to plasma.Of course, there is not even a trace of plasma here, since it is formed at much higher temperatures. These ovens are characterized as the most productive.

Rules for the safe use of homemade heaters

Observe safety requirements. Above all, do not leave the heater unattended or have children supervise it. It is strictly forbidden to use any equipment that could cause a fire. Do not place homemade heaters close to flammable items.

If you decide to equip a more thorough and efficient heating of the garage, for example, based on various kinds of stove structures, consider the fact that you can install the stove yourself only after obtaining permits from the fire service and the garage association.

Firefighters will recommend the most efficient and safest heating option for your particular garage, and the latter should simply be notified of your intentions.

However, the task is complicated by the fact that fire inspections in the overwhelming majority of cases do not give permission for the use of home-made furnace-type heating units. In the case of their unauthorized installation, all further responsibility will lie solely with the owner.

Thus, there is nothing difficult in assembling a garage heater yourself. To do this, you can use elementary and affordable components. Follow the instructions and everything will definitely work out.

Happy work!

Standalone gas burners

Self-contained gas burner

The third place in the rating is the best way, but since it involves the use of an autonomous heater, and we need methods of dealing with the cold, so to speak, “with bare hands,” he got to the third line.

The choice of autonomous heaters for cars today is quite wide. Among the many models, a liquid heater can be distinguished, for example, such as Webasto. Such heaters will not only warm the car interior, but also help start the car engine, as they are pre-heaters for the liquid. Only now they are expensive and you need to correctly install this heater on the car.

Now about completely autonomous heaters, among which gas heaters come out on top. They use infrared burners as the main element. Such a heater will not only warm up the interior, but also make it possible to boil tea or warm up food. But in addition to the heater, you will have to carry with you a bottle of liquefied gas. So for a passenger car, a five-liter cylinder is fine.

The video shows how an autonomous gas burner works:

One kilowatt is the rated power of such a burner and it is quite enough to keep warm. As for the flow rate, it is unlikely that more than 80 grams of gas will go off per hour. This means that you will be able to provide yourself with heat for a day or even more. The gas burner itself is very convenient, lightweight and compact. Carrying it will not cause any inconvenience, only in addition to the cylinder, as an additional equipment, you must not forget to take a lighter, a hose and a reducer with you.

Ignite the gas burner away from combustible materials and observe fire safety measures in every possible way. In addition, it will be necessary to periodically ventilate the interior so as not to suffocate in the smoke. Experts advise placing the gas heater in a special box in order to completely exclude contact between the burner and the car. Prometheus gas burners have proven themselves quite well.

Mobile device from a gas burner

Using this technology, it is possible to make a low-power, but rather easy-to-use portable heater.In this case, a gas stove-stove is used to assemble the device, intended for cooking, for example, in field conditions. It is also possible to make a heater using this technology and from a collet cylinder with a shut-off valve.

The power of a device assembled using a burner or a cylinder is, of course, not enough to heat a large summer cottage. But it is quite possible to effectively heat a small garden house in autumn or spring using such equipment.

Materials for the manufacture of a compact heater using this technology will require the following:

the burner itself;
a small sheet of tin;
metal kitchen sieve;
rivets.

Of the tools you will need:

drill with a small diameter drill;
riveter;
sharpened scissors for metal.

The gas heater is assembled using this technology as follows:

take a piece of tin and apply a sieve to it with the frame down;
carefully circle the sieve with a marker;
rectangular ears are added to the circle on the tin on four sides (one of which should be slightly longer than the other three);
cut out the workpiece with metal scissors;
bolt the cut out circle to the burner;
from above, bending the ears up, attach the sieve.

When the balloon is in operation, the sieve will subsequently play the role of a heat dissipator. You can improve such a design using a mesh as follows:

a circle with ears identical to the first is cut out of the tin;
holes are drilled in the circle with a small indent from the edge;
a strip of small width is cut from the mesh.

Next, the strip should be fastened to the first (above the sieve) and second circles by the ears bent at an angle of 90 ° on the rivets so that a cylinder is obtained.

Making a heater for the garage

To maintain a comfortable temperature in the garage, it is not difficult to make a waste oil heater yourself. At the same time, the problem of its utilization will be solved, which is also an urgent issue for car owners. For its assembly, almost all elements and spare parts can be found in your own garage.

When making a heater you will need:

metal pipes;
TEN (heating element);
waste oil;
wire with a plug.

Structurally, the body can be made in any form, convenient for placement in the garage. The photo shows one of the possible schemes of the device.

Diagram of a homemade oil heater

Metal pipes are used of any diameter. It must be borne in mind that the thinner they are, the more they will be needed. The temperature of the room will depend on the area that gives off heat. The length of the pipes is also arbitrary, it is desirable that it be maximum, but at the same time ideally in harmony with the dimensions of the wall on which it will be installed. The metal from which the pipes are made is not essential. The pipe wall thickness can be any.

The heating element is selected by power and voltage. Practice shows that 1.5-5 kW of a heater is enough for heating. Here it is necessary to take into account that the comfortable temperature of the garage and apartment differs significantly. And such a wide range of power is given based on the size of the heater. The voltage for connecting the heating element is taken as standard - 220 V. (we do not consider other parameters here).

Waste oil. Most motorists change the oil in their cars almost 2 times a year on their own. Therefore, working off, as a rule, is available to everyone. It remains to collect the required amount and start manufacturing the heater.

Homemade garage heater: how to make a device with your own hands

Some craftsmen make the unit with their own hands, using inexpensive materials. We invite you to familiarize yourself with the three most popular solutions for the organization of individual heating.

Before you make a homemade heater for a garage, you need to understand the principle of operation of each unit, its structure and study the assembly procedure.

Method thirteen well, this is really for extreme people

If you often find yourself in situations where you have to deal with the cold in the car (for example, you are a traveler), then you can take an ordinary wood-burning stove with you on the road. If you don't believe me, take a look:

A real oven in the car

Well how? Believe it? You can stock up on firewood or brushwood for free, for example, if your forced stop occurred in the forest or next to an old and dilapidated building, in which there are many boards.

If the car stalled in winter, then do not despair. Armed with one of the heaters listed above and having studied all the tips described, you will not freeze and survive in harsh weather conditions. Even being in the car at night, alone with the cold and harsh winter, it will be possible to create all conditions similar to home comfort in the cabin. So, do not hang up the nose of motorists!

The best prices and conditions for the purchase of new cars

It has long been known that a comfortable temperature for a driver is in the range from + 21 ... 23 degrees Celsius. Cold temperatures negatively affect focus and alertness while driving, causing irritability. And driving with limited visibility due to icy windows affects safety.

If you at least once had to get to your car in the parking lot during severe frosts or just sit in an icy car interior, just leaving a warm home, then you know firsthand that this feeling is not pleasant. And how I would like to warm up at this moment. You can, of course, run around the car or leave the snow while the interior warms up, but there are also less radical methods. As always, there is a way out and has long been known among motorists - an autonomous interior heater, which will gladly give comfort.

Working with pipes

After the scheme of the oil heater is selected, it is necessary to make its body. We make a drawing, determine the dimensions and start working with a grinder. The pipes are cut to length in the required quantity. After cleaning the ends, they are carefully and thoroughly welded. The operation of the entire heater as a whole will depend on the quality of welding. A leaking seam is not only a nuisance, but also a possible cause of a fire. When welding the ends of the pipes, leave one (on the lowest pipe) free. Subsequently, a heating element will be inserted into it. This means that the stub will have a different configuration.

Finished pipes are tied together. The piping is done with pipes, only of a smaller diameter. On the uppermost pipe, it is necessary to provide a place where the filler plug will be located. Structurally, it can be made in the form of a welded short squeegee with a coupling, one side of which will be welded. Using your plumbing and mechanical experience, the configuration of the heater can be made more aesthetically pleasing than the one in the photo. By the way, the body can be not only tubular. For this purpose, radiators from cars, old cast-iron radiators and other closed containers are well suited.

Electric garage heating

The easiest way is to heat the garage with electricity by adapting a suitable heater, purchased or homemade, for this. If there is no money to buy factory equipment, you can make it yourself. The simplest heating device is a goat heater, the most affordable, but also the least efficient. It is done easily and simply - some kind of non-combustible dielectric is taken, a wire of nichrome is wound around it.Next, we connect an electrical cable to the product and plug it into an outlet.

Among all the options for heating a garage, this option is considered the most dangerous - with electricity in general, jokes are bad. Bare nichrome wire is used here, there is no insulation. Users could be burned or electrocuted and there is a risk of fire. It is forbidden to leave such heating unattended. And in general - you should not use such artisanal and extremely dangerous heaters.

Electric heating of the garage can be organized with factory heaters:

Before you start choosing the type of heating, it is worthwhile to attend to at least the minimum thermal insulation of the garage. Otherwise, the heat will simply go out into the street.

Heat guns - they are extremely safe and provide fast heat injection into the garage. It takes a few minutes to warm up the entire volume, after which it will become warm in the room. Minus - increased noise level;
Infrared heaters are a modern solution with high efficiency. Infrared heating of the garage does not dry the air and does not harm your health. Simple IR heaters are used here, which do not heat the air itself, but the surrounding objects, as a result of which they begin to emit heat;
Electric convectors are a great way to heat up a garage in winter and not have to worry about installing or manufacturing complex equipment;
Electric boilers - in this case, a classic water heating using an electric boiler is organized in the garage. A boiler for a garage is selected in accordance with its area and heat losses, focusing on the formula of 1 kW of heat per 10 sq. m. area.

Heating the garage can also be organized with the help of a home-made boiler - for this you need an electric heating element of suitable power, which must be built into a metal pipe of one diameter or another. Further, bends are welded to the pipe, to which a water heating system with batteries is connected. By the way, the same batteries (heating registers) can be made independently using pipes with a diameter of 100 mm.

Garage Heating Planning Guidelines

Establish the main goal of organizing the heating system. Decide if the heater will be used to maintain a certain temperature around the clock, or if you will only turn it on while you are doing any work in the garage.

The best option for organizing heating is to connect the garage to the general heating system. To regulate the temperature in such a situation, ordinary valves can be used. The garage and the house must have at least 1 common wall. Therefore, this option is only suitable for individual garages located on the territory of a private land estate. Members of garage cooperatives have to solve the issue of organizing heating on their own.

The best option for organizing heating is connecting the garage to the general heating system

In accordance with current regulations, a garage heated by any kind of heating device must be provided with good ventilation.

Classic electric heaters

This is a rather wide area, as there are a lot of heaters that run on electricity. Everyone knows what an electric heater is, since it is they that we most often use in everyday life. All devices have practically the same principle of operation: thanks to the electric current, the spiral heats up, giving off its heat either to air or to a heat carrier (most often oil). It is logical that for the operation of heaters of this type, an electrical network is required.

Among the advantages of such devices are:

Ease of use.
Mobility and accessibility.
Good heating level.
The ability to control the temperature.

All you need to do is connect the device to the network and press a button. This is a good choice if you need to use heating periodically. I would like to note that there are such types of devices that you can buy:

oil-fired radiators;
heat guns;
wall convectors;
fans and heat curtains.

Each of them has its positive and negative sides. It is unprofitable to use such devices to regularly heat the garage. Such heaters cannot be called energy-saving. Their use is rational for short-term use.

When choosing equipment, pay attention to the degree of fire safety of the device and its power. Remember, most often a garage fire occurs precisely because of a breakdown of an electric heater.

Another heater option

This design is also based on thermal film. The unit is easy to manufacture and is perfect for heating a garage. Prepare everything you need for work in advance.

Heater assembly kit
Paper plastic. Prepare a couple of pieces of this layered material. Each element should have an area of about 1 m2.
Wire with working plug.
Graphite. It will need to be thoroughly ground into powder.
Epoxy based adhesive.

The first stage is the preparation of the guide. In this case, the functions of the conductor fall on a mixture of epoxy glue and ground graphite. The resulting adhesive will have high resistance, which is what you need. The maximum possible heating of the future heater depends on how much graphite you add. On average, the temperature reaches 60-65 degrees.

The second stage is the preparation of the main part of the heating unit. Apply the glue prepared in the previous step to the plastic sheets. Make zigzag strokes. The mixture should be applied to the rough side of the plastic sheet. Fasten the sheets face to face with epoxy glue. For additional fixing of the sheets, make a frame of wooden slats.

The third step is to install the copper terminals and complete the job. Attach copper terminals to the previously installed graphite conductors. Leave the device to dry. Even a small amount of moisture will harm the device when it starts up. After the structure is dry, measure its power and determine the resistance, just as you did with the previous heater. It is strongly discouraged to connect the device to the network without first checking it. it is dangerous. In the end, it remains only to connect the power cord to the device.

The third step is to install the copper terminals and finish the job

Such a device is perfect for heating a garage and all sorts of other small spaces. To achieve maximum heating efficiency, the device is recommended to be used in conjunction with the previously discussed device. No hard-to-reach and expensive components are required to assemble the unit. Despite the simplicity of design and manufacture, a homemade heater fully solves all the tasks assigned to it.
