Homemade heaters for home, cottage and garage

Rarely does anyone provide for heating when building a garage. 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 themselves, using inexpensive materials. We invite you to familiarize yourself with the three most popular solutions for organizing individual heating.

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

Improving a homemade heater

If you plan to use a similar design of an oil heater in another place, for example, in a country house, then some changes will have to be made to it.
They will only affect the electrical part. The fact is that you are in the garage temporarily, but in the country house, compared to the garage, you are permanently. Therefore, the requirements for room temperature will be different. To achieve comfortable heating conditions for a country house, the electrical circuit of the heater must be slightly changed. To do this, a relay is introduced into the heating element circuit, which will control the heating of the element and maintain the specified temperature of the coolant. And again, an old electric iron, or rather its bimetallic plate, can play a positive role. In the iron it served as a regulator of its heating; here its purpose will be the same - to maintain the specified oil temperature. In addition to the direct effect, there will be an additional effect - energy savings. The relationship is direct - the lower the temperature, the less electricity is consumed.

Bimetallic iron plate

A homemade designed oil heater completely replaces a purchased one, and in some respects even surpasses it. This is, firstly, manufacturing to the required dimensions. Secondly, tangible savings in material resources

Of no small importance will be the fact that the garage will be cleared a little of unnecessary rubbish (pipes, cutting corners, profiles), from which a useful and necessary thing will be made

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

Autonomous heating device

This heater is designed for 12 volt current. Thanks to this, it can be connected to a battery. It can be used in rooms where there is no heating and where renovations are being carried out, as well as in the garage or any room in the house. Its power is not enough to heat the entire room. It does not create infrared rays. It only heats the air.

To make it you need to take:

Metal can. It could be a coffee can. Its height and diameter should be 20 and 10 cm, respectively. These values may deviate upward or downward. You should not use a jar made of plastic, cardboard or any other material. This is because they are poor conductors of heat.
Bracket. It can be a U-shaped part of a children's metal construction set.
Bayonet cartridge.
Car brake light lamp. It is designed for 12 volts. Its power is 25 W.
2 A fuse.
Sleeve made of insulating material.
Cable. The cross-sectional area of one wire must exceed 1 mm².

Sequence of manufacturing an autonomous heater

A 12 volt device is made as follows:

Drill 20-30 holes in the side wall of the can. Their diameter should be 3 mm.
Make a hole in the bottom of the jar. It is drilled in the center of the bottom. The diameter should be equal to the diameter of the bolt that will secure the bracket.
Fix the bracket at the bottom of the can.
A cartridge is secured to the top of the bracket. This element must be positioned so that the lamp does not touch the walls of the container.
A hole is drilled in the side wall of the can at the level of the top of the bracket so that the bushing for the cable fits in it.
A sleeve is inserted into this hole and an electrical wire is pushed through it, through which a current of 12 volts will flow. The cable will be connected to the socket.
Screw in the lamp and close the jar with a lid.
A fuse is connected to the cable break.

The 12 volt heater is ready. Now all you have to do is connect it to the battery and wait 10 minutes. During this time, the homemade garage heater will warm up. When using a device with an operating voltage of 12 volts, you need to monitor the battery voltage. It should not fall below 10 volts. Otherwise, the current source cannot be restored.

Heating cables

Laying a heated 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 significantly simplify the task. In addition, you can lay the cable only under the car and turn it on only if you have problems starting the engine.

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

Fireplace

Diagram of an electric fireplace with an air heating element and a double convection circuit

You can improve an ordinary electric fireplace, or make your own efficient one based on a purchased heating element, using an additional casing that creates a secondary convection circuit. From a conventional electric fireplace, firstly, the air flows upward in a rather hot but weak stream. It quickly reaches the ceiling and through it warms more of the neighbors' floors, attic or roof than the owner's room. Secondly, the IR coming down from the heating element in the same way warms the neighbors below, the subfloor or basement.

In the design shown in Fig. on the right, downward IR is reflected into the outer casing and heats the air in it. The thrust is further enhanced by the suction of hot air from the inner casing, which is less heated from the outer casing at the narrowing of the latter. As a result, the air from an electric fireplace with a double convection circuit comes out in a wide, moderately heated stream, spreads to the sides without reaching the ceiling, and effectively heats the room.

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 heated. This is the key difference between infrared devices and other types of heaters, which primarily heat the air.

The main element of the type of heaters under consideration is the emitter. In household devices, the operating temperature of the emitter can reach 600 degrees. In addition to electric IR 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:

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

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

Micathermic. The emitter 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 two previous 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 emitter, but the tube contains an inert gas

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

Carbon. Another representative of tube emitters. The vacuum quartz tube contains a carbon filament, which ensures maximum efficiency compared to halogen and quartz devices. The cost of carbon emitters is the highest compared to analogues.

In garages, IR heaters with aluminum emitters are usually used - they are cheaper, more reliable, and much more durable, which is important when using 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, so such heaters meet fire safety requirements. Such devices are also supported by the fact that they do not burn oxygen, and a person can stay in a heated room for a long time without any problems.

Such devices are also supported by the fact that they do not burn oxygen, and a person can stay in a heated room for a long time without any problems.

When choosing a heater with a plate emitter, you must find out what the thickness of the anode layer is - for normal and long-term operation of the device, this figure must exceed 25 microns. The heating element must be located in a stainless steel housing that will not rust in high humidity in the room.

Infrared heaters for garages have the following number of advantages:

Possibility of uniform heating of the entire room or creating local heating in a specific area;
The ability to warm up any area of the garage, including even the most inaccessible ones.

Portable tile heater

Small rooms, a garage, a greenhouse, a tent can be conveniently heated with a portable tabletop gas heater. Such a device is constructed from a quadrangular flat tile equipped with a metal grid.

Assembling this device involves attaching part of the gas stove to a metal casing. Due to the installed combustion chamber, the air is heated to the desired temperature, and several or one fan ensures the supply of warm air and its circulation throughout the room. The assembly of such a device consists of several stages and does not require special technical knowledge.

A gas heater made according to this design is more powerful than the previous version. With the help of such a device it will be possible to heat small rooms even in winter.

The first stage is working with measuring tools. You need to use a ruler or tape measure to take accurate measurements from the quadrangular tile. This will be required to determine the parameters of the heater housing. After taking measurements, you need to cut out blanks from a tin sheet using scissors. Next, the blanks are fastened with rivets into a casing.

Then the casing is fixed with hook strips on the tile. In order for it to be quickly removed and mounted back, you need to make a movable bar. Such a bar can be easily made using a small spring, which is connected to a lifting lever.

Thanks to this solution, in the future it will be possible to easily remove the casing for cleaning or transportation. The homemade scheme under consideration assumes the presence of a special ventilation system. To install it you will need a simple fan without any additional complex devices or materials.

Instead of tiles, you can also purchase a ceramic infrared burner. The infrared heating system provides heat distribution similar to solar radiation. Such heating does not heat the air, but objects, which then radiate heat

A small fan from any home device is suitable for installing ventilation. You can use scissors to adjust the size. Trimming and giving the desired shape and size to the fan blades takes about half an hour. After carrying out these steps, you need to install a ready-made fan behind the heater housing so that there is draft inside the housing.

You also need to install a metal combustion chamber. The combustion chamber body must be studded with many small holes. They can be made using an electric drill and a metal drill or using a hammer and nail. The holes should be a short distance from each other.

You also need to purchase a rubber hose with an adapter to connect the flat tile to a gas pipe or gas cylinder. A fan installed at the rear of the casing ensures the supply and distribution of warm air over a fairly wide range in the heated space.

The gas flows through the hose to the burner. The burner burns the resource and heats the heat emitter, which releases thermal energy to the room. At night, such a heater illuminates a small area around itself

Such a homemade gas heater copes well with the task of heating a room not only in the autumn-spring period, but even in winter. Also, such a device consumes gas economically and has a high efficiency.

Design and features of convector heaters

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

In heating convectors, everything happens in strict accordance with this principle - i.e. the air moves naturally, heating up in the inside of the heater. Increasing the intensity of cold air intake significantly increases the heat transfer of the convector.

Typically, convection heaters are installed on walls - this allows the device to draw air from below 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 regulate the direction of movement of heated air.

There are several types of convectors:

Electrical. They are easy to install and operate.
Gas. The main distinguishing feature of these devices is their high power. When installing gas heaters, you need to provide a high-quality chimney for supplying air and removing combustion products. In small spaces, only devices with a closed combustion chamber can be used.
Mermen.

Among the advantages of convector heaters it is worth noting:

Low temperature of the device, which eliminates the possibility of burns upon contact with it;
Limit degree of fire safety of electrical devices;
Simplicity of design and minimal likelihood of breakdown.

Main stages of heating installation

Ideally, you should think about heating when preparing to build a building for storing equipment. This makes it possible to immediately build a warm garage - for example, it is quite difficult to insulate a hangar with thin metal walls.

A layer of heat insulation on the walls and ceiling of the room will help reduce heat loss. It is recommended to insulate the walls from the outside and cover the thermal insulation layer of mineral wool or foamed polymer with external cladding.

The room is provided with high-quality ventilation. At the same time, it is necessary to eliminate all holes and cracks through which warm air flows out.

Wiring

If electricity is required to operate the circulation pump of a liquid heating system, an electrified building does not require additional wiring. But electric garage heating requires installation of wiring with suitable parameters. It must be grounded, and the cross-section of the wire is selected in accordance with the power of the heating device.

Chimney and heating circuit

The chimney of a real heating boiler is an insulated sandwich pipe - this design lasts longer due to the absence of metal-destroying condensate.

If the room is heated by a potbelly stove, they try to mount a single-layer chimney from several elbows located at an angle in order to increase the heat transfer area. And the water jacket is often mounted not on the stove body, but on the pipe, since a noticeable part of the thermal energy of the burning fuel escapes into the atmosphere with the smoke.

Heating radiators are selected taking into account power and service life. It is enough to install steel panel, tubular or sectional batteries.

Polypropylene pipes are suitable for installing a water heating pipeline. Products of the PN25 brand are designed for an operating temperature of 90°C and can withstand high pressure. Steel pipes are also suitable, but their installation will require the use of a large number of connecting fittings or the use of a pipe bender. When installing heating with your own hands, for a system with a circulation pump it is enough to use a pipe with a cross-section of 20-25 mm.

What is needed to make a heater?

In every garage you can find a lot of useful things that at first glance do not seem to be of much value, but in the hands of a skilled owner they can turn into useful devices or devices. In its design, a homemade heater resembles factory analogs, where the operating principle is based on the fact that the heating element, in this case a nichrome spiral, is hermetically sealed between 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

Fiberglass.
Glue Monolith.
Nichrome wire.
Electrical wire.
Metal rivets.
Electric drill.
Matches.

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

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

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

Electric heaters made of wire and spiral: diagram and principle of operation

It’s even easier to assemble a heater from nichrome wire with your own hands. For work you will need materials:

fiberglass 50*50 cm;
24 meters of nichrome wire Ø 0.3 mm;
epoxy glue 150 g.

The manufacturing principle is as follows: the surface of a square panel made of fiberglass is evenly covered with nichrome wire, the ends of which are brought out to the current supply elements. Then the entire area is filled with epoxy glue and covered with a second textolite panel. After the glue hardens, the finished “sandwich” is connected to a power source and can be used to heat the garage.

Step by step assembly. For fiberglass panels, the inner and outer faces are determined, the inner faces are sanded with sandpaper and cleaned.

Making a tabletop fan heater

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

This type of heater is convenient because it allows you to regulate the heating temperature and the rotation speed of the cooler.

Selection of 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-amp 12-volt power supply;

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.

The tools you need to prepare are:

jigsaw;
hammer drill or drill;
soldering iron;
hole saw;
glue for woodworking;
“moment” or superglue;

To clean wooden workpieces, removing burrs along the edges, you will also need fine-grained sandpaper.

Assembly of body parts

The future heater will have the shape of a cube. The body of the device is assembled from wooden boards 9 mm thick.

two square blanks measuring 12*12 cm;
3 parts 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, each 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 blanks 12x12 cm. Marking the location of the holes is applied directly to the patterns. They are applied to each side and drilled through.

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

In each of the four rectangular blanks measuring 1 * 1.5 mm, holes D5 mm are made.

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

A square blank with a 9 cm drilled hole is installed inside the body. After this, the last rectangular part 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 whether the spring is suitable, you need to connect it to a 12-volt power source and take measurements using a multimeter.

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

The selected spring is soldered to copper rods, the ends of which are fixed to blanks measuring 1x1.5 cm. The assembled structure is glued to the corners of the body. The bare “tails” of the electrical cable are soldered to the ends of the rods. After this, a bar equipped with holes is attached.

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

If all structural elements are connected correctly, then when the rheostat is turned on, a blue light will light up on the LED strip. When the switch is turned on, the LED strip will acquire a red tint, which will create a violet color against the background of the main blue. After this, 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.

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

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

No. 3. Solid fuel heating

Heating with coal, wood, peat, or pallets is profitable - the fuel is cheap, and its heat transfer, although lower than that of gas, is still quite high. Potbelly stoves, stoves and boilers are used to burn solid fuels.

A common disadvantage of all solid fuel stoves is the need to equip a place for fuel. It is also important to ensure constant control over the amount of fuel in the firebox. This adds concerns about keeping the chimney and firebox clean, but the heat itself is very cheap. Solid fuel boilers and brick stoves are placed only on a solid, non-combustible base.

Potbelly stove for heating a garage

Potbelly stoves are the most primitive stoves that began to be actively used at the beginning of the last century. Then their popularity sharply decreased due to the spread of centralized heating. However, potbelly stoves are still used, because they are practically the cheapest way to heat a garage.

The potbelly stove is made of metal. The largest part is occupied by the chamber into which the fuel is thrown. The room warms up due to the contact of the stove walls with the surrounding air. Not the least important role is played by the pipe, which also accumulates heat. To prevent heated combustion products from immediately flying out into the street, a pipe of a clearly defined diameter is used, due to which the warm gases make several revolutions in the vertical plane. This allows you to make maximum use of the heat of combustion of the fuel (efficiency reaches 60-80%) and effectively suck in the air necessary for the fuel to burn completely. The diameter of the pipe in mm should be 2.7 times greater than the volume of the stove in liters.

It is important that the chimney has a complex shape: first there is a vertical insulated part, then a horizontal or inclined part, the so-called. hog, which provides up to a quarter of the heat received, because the flue gases burn out here. Potbelly stoves are sold ready-made: there are both the simplest and most primitive options, as well as sophisticated designer ones. If you have the skills, you can assemble a potbelly stove yourself from a barrel or sheet metal.

Advantages:

a potbelly stove can be heated with any solid fuel, but wood is usually used;
low price and low cost of operation;
relatively high efficiency;
allows you to quickly warm up the room and dry the air in it;
There are models that can also be used as a stove. They will come in handy for those who spend even too much time in the garage.

Minuses:

the need for constant monitoring of work;
high fire danger;
Suitable for small spaces only;
the air cools quickly;
it will be impossible to get rid of the specific smell;
the need for regular chimney cleaning.

Solid fuel boiler

This is a more expensive, but at the same time, safer and more effective solution. The principle of operation is simple: fuel is burned in the firebox, a container with coolant is heated, which is supplied through pipes and radiators. improved types of boilers are increasingly used

a pyrolysis boiler has two combustion chambers, in the first the firewood smolderes at a high temperature due to the fact that the amount of air is insufficient. The combustion product is pyrolysis gas, which is burned in the second chamber, releasing much more heat than just wood. The boiler efficiency increases to 90%, and one portion of firewood lasts for 10-13 hours;
Pellet boilers are fired using pellets obtained from wood waste. They are placed in a bunker, from where they are fed into the firebox in doses. The boiler efficiency reaches 95%; fuel can be loaded once every few days.

The body of solid fuel boilers is made of cast iron or steel. Pyrolysis and pellet boilers are, of course, very convenient, but they are expensive. If funds allow, you can afford such a purchase - it will soon pay off.

Brick oven

Building a brick oven in a garage is a long, expensive and painstaking task. The fuel for such a stove is usually wood, but coal can also be used. The principle of obtaining heat is still the same. The fuel burns, heats the walls of the stove, and they heat the air. A good option for small spaces. Brick takes longer to warm up than metal, but it also cools more slowly.

Stove Buleryan

The Buleryan stove is often confused with a potbelly stove and a regular wood-burning stove. She actually absorbed a little bit of both. The operating principle is based on convection. The design assumes the presence of pipes at the base of the furnace and in the upper part. Cold air enters through the bottom of the stove, receives heat from the chamber where the fuel is burned, and exits, already heated, through the top. The pipes are 2/3 soldered into the furnace body to ensure maximum heat transfer. The special design of the firebox and chimney allows you to extract maximum heat from fuel combustion. The presence of a chamber for pyrolysis combustion of fuel plays a significant role here. Combustion products are removed through the chimney.

Advantages:

rapid heating of the room due to convection and heat transfer from the surface of the stove;
compactness;
there is no need to frequently add firewood;
higher safety compared to a potbelly stove.

Minuses:

price;
complexity of chimney installation;
the need for frequent cleaning of soot.

Stages of assembling a homemade heater

After all materials, tools and accessories are prepared, you can begin assembling a homemade heater:

DIY garage heater

Fiberglass sheets are cleaned from the inside with fine sandpaper.
Markings are made - a line is drawn in the upper and lower parts, retreating 2 cm. On the right and left sides of the sheet, the indentation will be 3 cm. The heating coil will be attached to one sheet, for which it is necessary to make several holes on both edges of the sheet. Two more holes must be drilled to secure the electrical supply wires. They are located on the edge where a 3 cm indentation is left.
Before you make 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 finishing the work.
The spiral is laid in rows, starting each row by a match in the hole. A distance of 8-12 mm should be maintained between rows. Every 5-7 cm, the spiral is secured with paper centimeter strips, onto which Monolith glue has been previously applied. When the entire spiral is evenly placed on the panel, the matches can be removed, and these places can be further strengthened with paper strips with glue.
Metal rivets are inserted into the side holes, onto which the stripped ends of the electrical wire are wound. On the outside of the fiberglass plate, a washer is placed 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 you connect the product to an ohmmeter and a power outlet.
Now you need to glue the second sheet, for which epoxy-based glue is used. You need 150 grams of it. Epoxy resin is applied between the rows of the spiral and a second panel is placed on top. In order for gluing to occur efficiently, a sheet of plywood is placed 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 epoxy resin is a day. On the second day, you can already use the 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.

Autonomous heating device

To make it you need to take:

Metal can. It could be a coffee can. Its height and diameter should be 20 and 10 cm, respectively. These values may deviate upward or downward. You should not use a jar made of plastic, cardboard or any other material. This is because they are poor conductors of heat.
Bracket. It can be a U-shaped part of a children's metal construction set.
Bayonet cartridge.
Car brake light lamp. It is designed for 12 volts. Its power is 25 W.
2 A fuse.
Sleeve made of insulating material.
Cable. The cross-sectional area of one wire must exceed 1 mm².

Infrared wall heater

Sequence of manufacturing an autonomous heater

A 12 volt device is made as follows:

Drill 20-30 holes in the side wall of the can. Their diameter should be 3 mm.
Make a hole in the bottom of the jar. It is drilled in the center of the bottom. The diameter should be equal to the diameter of the bolt that will secure the bracket.
Fix the bracket at the bottom of the can.
A cartridge is secured to the top of the bracket. This element must be positioned so that the lamp does not touch the walls of the container.
A hole is drilled in the side wall of the can at the level of the top of the bracket so that the bushing for the cable fits in it.
A sleeve is inserted into this hole and an electrical wire is pushed through it, through which a current of 12 volts will flow. The cable will be connected to the socket.
Screw in the lamp and close the jar with a lid.
A fuse is connected to the cable break.

The heating device made will work until the lamp fails. Its functionality can be restored by replacing the lamp. You can even put a halogen lamp in its place.

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 – total volume of the room,
dT – temperature difference between indoors and outdoors,
K – heat loss coefficient.

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

0.6-0.9 – the garage is well insulated;
1-1.9 – garages have average insulation quality;
2-2.9 – the garage has insufficient 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.

OCD

Model using IR silicate glass

Since IR silicate glass is used, products of different brands experience sharp changes in thermal conductivity and transparency. For this reason, make and test one emitter. Based on the test results, it may be necessary to vary the diameter of the material.

The following arithmetic principles should be taken into account for quartz installations.

Material parameters

0.5 mm: power – 350 W, current – 1.6 A.

0.6 mm – 420 W and 1.9 A.

0.7 mm: 500 W and 2.27 A.

0.8 mm: 530 W and 2.4 A.

0.9 mm: 570 W and 2.6 A.

Thin wires have a solid radiating surface. When using thick versions, exceed the IR power that glass can transmit.

Testing

The finished product is placed vertically on a non-flammable surface. Supported with a heat-resistant object. A current of 3 A is supplied to the product. A digital tester is used to monitor the current.

We need to check the behavior of the glass. If it quickly heats up and cracks within half an hour, it is not suitable.

After 1.5 hours, the radiation power is checked. Place your palms parallel to the radiating planes. The distance from them is 15-17 cm. You need to hold it for at least 3A min. Then you will feel a soft warmth for 5-10 minutes. If your palms immediately get burned, you need to reduce the diameter of the wire. If after 20 minutes there is not even slight heat, thicker material is needed.

Criteria for choosing a heater

A garage is a non-residential premises used not only for storing vehicles, but also for repairing them. Accordingly, in addition to the four/two-wheeled “friend”, it also stores 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 only be heated with the help of heaters powered by electricity.

When thinking about which heater to choose for a garage, it is important, first of all, to determine for yourself the basic criteria that it must meet in its operation:

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 residential premises, its owner can often spend a considerable amount of time in it and the type of air he breathes plays an important role;
ease of operation, installation, etc. - undoubtedly an important criterion, since setting up a heating device is not the purpose for which the garage owner visits it;
autonomy.

A little later we will look at a wide variety of options for heating devices, but before we begin to familiarize ourselves with them, it is important to determine for ourselves what functions they will perform. This depends, first of all, on the area of the building, the presence of ventilation in it, etc.

Some people note that it is more convenient to work when the room temperature is not very high, 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.

What should be considered at the preparation stage?

A garage made of metal, brick, concrete or sandwich panels is a structure with high heat loss. If you do not provide reliable thermal insulation , then you will be heating the street. It is best to arrange external insulation of the garage, but if this is not possible, then you can get by with internal insulation. Not only walls, but also gates and floors need thermal insulation.

The heating system must be safe . A lot of flammable liquids and objects are stored in the garage, so the organization of heating must be taken with full responsibility:

at the planning stage , make a diagram of the garage , on it you need to mark the storage location of fuels and lubricants. This warehouse should be located as far as possible from the heating device and located at some elevation. The plan also marks the place where the pipe exits through the ceiling or wall, unless, of course, the selected heating system provides for the organization of a chimney. It is also worth noting wooden surfaces near heating equipment - they are covered with sheets of galvanized steel. Don't forget to make room for a fire extinguisher. If a system using flammable fuel is chosen, it would be a good idea to provide space for a box with asbestos fabric;
the floor and walls near the heating device should not be flammable;
the heating system must not be left unattended;
electrical wiring must be grounded;
it is important to provide reliable ventilation so as not to become another victim of carbon monoxide poisoning;
It’s better not to store all the junk in the garage that doesn’t have a place at home - it’s these things that become food for fire;
It is better to smoke outside or, at least, as far as possible from heating appliances;
electrical systems are not suitable for damp areas;
It wouldn’t hurt to install simple smoke detectors to protect your own property and neighbors’ garages.

Movement

Run to keep warm

Don't know how to keep warm in the car if the methods described above do not work for you? Remember the main character from the film “The Irony of Fate or Enjoy Your Bath”? That shot of him jumping on the spot and jogging to warm up. In fact, this is the most effective way to warm up, but at the same time the simplest. That is why it ended up on one of the lowest lines of the rating.

We can recommend the following: turn on the music (if your mobile phone has enough charge), put on headphones and beat out the rhythm with almost all parts of the body to a catchy melody.

It is also useful to periodically rub your limbs to prevent them from going numb.

If it doesn’t help, then you need to leave the salon. And quickly run around the car for as long as possible. You need to breathe slowly and evenly. After warming up, you should not stay outside. Get back in the car. If you freeze, go out again.

Selection of materials

As is clear from the above, to obtain a homemade heater you will need to get the following components somewhere:

frame;
oil;
heating element;
mobile stand;
control and automation devices.

As a housing, you can borrow an old radiator from a central heating system, sheet or sectional. A car, or any similar product, the design of which will allow fluid to circulate inside naturally or artificially (using an electric motor), is also quite suitable. You can also make a closed loop from steel pipes with your own hands.

The main thing is not to forget that an indispensable condition for the normal functioning of the system will be to ensure the tightness of the housing. If the liquid begins to leak, then it is unlikely that such a homemade device will bring more benefit than it will cause trouble.

As for the oil, firstly, its quantity should be based on the calculation

85% of the body volume. The rest of the cavity is filled with air. This 15% area is maintained so that during operation the oil does not crush the housing due to thermal expansion.

Secondly, the quality characteristics of the liquid must satisfy at least two criteria: purity and heat resistance. Dirt and impurities will shorten the life of the heating element by causing scale to settle on it. A decent temperature of the heating element indicates that you should select technical oil of the appropriate brand. A suitable option would be, for example, a transformer.

Thermos seventh place in the ranking

An ordinary thermos, preferably a large one, will help keep you warm inside the car. Or rather, not he himself, but his contents. Hot tea has a good effect on blood circulation and does not constrict blood vessels, such as coffee. It’s best to carry just a thermos with a hot thyme drink. This tea will warm you up very quickly. As is known, the substances contained in this herb growing in the mountains are very beneficial for the human body. Since ancient times, frostbitten travelers were warmed with just such tea, giving it to drink.

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

The British would advise drinking a little 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 in road conditions it can simply be mixed with hot water. It will not only help you stay warm in winter, but will also lift your spirits. But it’s better not to get carried away with alcoholic drinks, such as vodka, while sitting in the car. They only provide illusory warmth, but in reality the consequences can be disastrous. “Under alcohol” you can easily fall asleep and freeze.

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

Review of popular models of garage stoves

There are a variety of options for garage stoves on the markets. They differ in the heating principle and design solutions. Some models deserve special attention:

The Bullerian stove is made to run on solid fuel. The design has a convection mechanism for high-quality heating of air masses that move through the pipes;
a durable option is the Stavr stove. It is made of cast iron, a similar material can withstand high temperatures;
Termafor stoves have convection pipes in their design, which are placed in the combustion chamber. Such models are designed for both standard and pyrolysis combustion;
The Alaska stove has a stylish design and good heat output. The design is equipped with a hob;
A cheap alternative to Buleryan is the model of the domestic manufacturer Breneran. It can operate on wood and waste from the manufacturer.

Heating with liquid fuel

Do-it-yourself budget heating of a garage can be done using liquid heating units, including homemade ones. In our reviews, we have already described exhaust furnaces that provide cheap, and in some cases, free heat. For example, if you are changing engine oil, then over 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.

Pyrolysis-type furnaces consisting of several parts, as shown in the figure, give good results. A fire is lit in the oil container, as a result of which oil vapors and pyrolysis products begin to form. They are burned in a vertical pipe with holes, producing a large amount of heat. By regulating the access of oxygen, you can adjust the intensity of combustion.

When using any stove, it is better to allocate a separate corner for it. You also need to think about a reliable foundation and lining the adjacent walls with non-combustible materials.

Using a stove with a plasma bowl to heat your garage, you can achieve maximum heat transfer and minimum fuel consumption. The oil here breaks down into its constituent parts in a hot bowl, after which it burns to form a bluish-white flame, similar to plasma. Of course, there is no trace of plasma here, since it is formed at much higher temperatures. These furnaces are characterized as the most productive.

How to organize air heating

This heating method involves direct heating of the air in the garage from a selected heat source. This can be any of the following units:

solid fuel stove;
furnace - dripper in production;
electric heater - convector, oil radiator or heat gun;
gas convector.

Such heaters emit diesel combustion products directly into the room

Installation of a wood-burning and exhaust stove

Direct heating of the air in the garage by burning cheap fuel - firewood and various waste - is the most economical heating method. But you need to organize it wisely, otherwise the heater will heat one corner of the room, while the opposite one will remain cold. It is clear that you cannot install a stove in the middle of the room, which means that the issue of heat distribution must be solved differently.

To make effective air heating of a garage or box with your own hands using a wood stove, use our recommendations:

Order, buy or make an economical potbelly stove yourself, not just an iron box with a pipe. You will find examples of furnaces with drawings, diagrams and assembly instructions in the corresponding publication.
The heat exchange surface area of the heater walls must correspond to the dimensions of the room. The calculation is as follows: in order to add logs at intervals of 3-4 hours and evenly warm up a 20 m² garage, the heating surface area should be 1 m².
The part of the housing around the ash pan is not taken into account (it heats up slightly). But the area of convective fins welded to the walls from the outside is taken into account.
Install the potbelly stove in the chosen location and be sure to organize airflow around the case with any fan - household, for hoods or a computer cooler. Thanks to the forced air movement, heat is more efficiently removed from the walls of the firebox and distributed more evenly throughout the box.
Before venting to the street, lay the chimney horizontally along the wall, so it will release more heat into the room.
Raise the chimney pipe to a height of 5 m, counting from the grate, and equip it with a damper to adjust the draft. Provide a condensate collector at the bottom; adjust the cap at your discretion.

There are designs of homemade stoves designed for air heating of workshops, garages and other outbuildings. Below is a diagram of a potbelly stove made from a gas cylinder and equipped with a separate heating chamber through which air is blown by a fan. If necessary, water can also be driven through the heat exchanger.

All of the above applies equally to potbelly stoves using waste oil. The only difference is the placement of the fuel tank that feeds the dropper. Keep the tank away from the stove to prevent fire. Do not use a regular two-chamber miracle heater - it is a fire hazard and consumes up to 2 liters of waste per hour. Use models with a drip burner.

Placement of electric heaters

The first thing you need to do is to choose the right electrical heating appliances based on power. If you want to heat the entire garage, then measure its area and multiply the resulting quadrature by 0.1-0.15 kW. That is, a box of 20 m² will require 20 x 0.15 = 3 kW of thermal power (and it is equal to electrical power), sufficient to maintain positive air temperatures.

Now let's move on to the recommendations:

If your work in the garage is periodic and short-term, it is better to save money and buy a portable fan heater or infrared panel. It is located in the right place and heats only part of the room. The thermal (also known as electrical) power of the device is 50% of the calculated one.
Try to use heaters equipped with a turbine or fan to distribute heat better and faster.
A rational solution for convectors and other wall-mounted appliances is to install several small heaters at different points instead of one large one. Then the garage will warm up evenly, and if necessary, half of the heaters are turned off.
Do not follow the lead of sellers who are trying to sell a more expensive device under the guise of an innovative and high-tech product. The efficiency of all electric heaters is the same and equal to 98-99%, the difference is in the method of heat transfer.

Different heating methods can be combined. For example, it makes sense to hang an infrared panel above a workbench to provide local heating. Heat the rest of the garage with a stove or a heat gun - whichever is more profitable. Don't forget about garage ventilation - it is necessary when burning any type of fuel.

Autonomous gas burners

Autonomous gas burner

Third place in the ranking is the best method, but since it involves the use of an autonomous heater, and we need methods of dealing with the cold, so to speak, “with our bare hands,” it ended up in third place.

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

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

The video shows how an autonomous gas burner works:

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

You should light a gas burner away from flammable materials and observe fire safety measures in every possible way. In addition, you will need to periodically ventilate the interior so as not to suffocate in smoke. Experts advise placing the gas heater in a special box in order to completely eliminate contact of the burner with the car. Prometheus gas burners have proven themselves to be quite good.

How to assemble an oil heater yourself?

Why do many people decide to create an oil radiator with their own hands for the garage? They gained their popularity due to their impeccable functionality, efficiency and excellent characteristics. They are completely safe, compact, easy to use, and have a fairly high efficiency. The design of such devices is very simple: a sealed housing containing oil and tubular electric heaters wrapped around it.

To build such a device, you need the following tools and materials:

A completely sealed container - it can be a car radiator, an aluminum or metal battery.
Four heating elements.
Technical or transformer oil.
Low power pump or electric motor.
Drill, set of drills, welding machine, switches, electrodes.

An oil heater is manufactured according to the following scenario:

Frame installation

It is important to make it easy to use and transportable. It is also necessary to consider how it is stored in the summer.

Using a welding machine, the corners are connected to each other. Hole for installing heating elements. They can be made by welding or a grinder. Mounting the motor or pump. You can install the pump or motor on the heater body itself or its frame. The main thing is to make sure that it does not come into contact with the heating elements. Installation of heating elements. They are installed in an already prepared place using bolted connections. Tightness. It is necessary to weld all the holes to achieve a tight seal. For ease of use of the device and unexpected oil drainage, it is better to mount a cover that can be screwed to the body. Connecting heating elements. This should be done in parallel for more efficient work. It is convenient to select the temperature using the regulator. The heater is almost ready, all that remains is to assemble everything directly on the frame and ground it.

To relax in the countryside in winter, you need a reliable source of heat (heater). It can be purchased in specialized stores. But there are summer residents who can easily design homemade heaters for their home, cottage and garage.

Not all summer residents and homeowners come to this decision, but only those who have special skills and abilities. Among them there are real self-taught engineers. They are able to calculate everything down to the smallest detail, carefully handle every detail, installing an original safe heater.

The cost of material for a homemade device for heating a room is minimal, since it can be found on the farm. Even if you buy the material for money, it will cost much less than a device from a store, and the effect of the work is the same. Why then spend money on purchasing ready-made equipment when you can install it yourself. How to make a home heater with your own hands?

Making a heater for the garage

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

When making a heater you will need:

metal pipes;
heating element (heating element);
used oil;
wire with plug.

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

Diagram of a homemade oil heater

Metal pipes are used of any diameter. It must be taken into account that the thinner they are, the more of them will be needed. The temperature of the room will depend on the area giving off heat. The length of the pipes is also arbitrary, it is desirable that it be maximum, but at the same time ideally harmonize with the dimensions of the wall where it will be installed. The metal from which the pipes are made is not significant. The thickness of the pipe walls can be any.

The heating element is selected by power and voltage. Practice shows that 1.5-5 kW of heater is quite enough for heating. Here it is necessary to take into account that the comfortable temperature of the garage and apartment differ significantly. And such a wide power spread 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).

Used oil. Most car enthusiasts change the oil in their car engines themselves almost twice a year. Therefore, as a rule, everyone has work off. All that remains is to collect the required quantity and begin making the heater.

Homemade product #1 - based on the “Good Warmth” heater

Many heating devices operate according to the so-called “thermal film principle.” For example, the well-known “Kind Warmth”. Assembling its analogue at home will not be difficult. For this you will need:

Laminated paper plastic. Two sheets of equal size with an area of about 1 square. m.
Graphite powder. You can grind graphite yourself, for example, old graphite trolleybus brushes.
Epoxy adhesive.
A piece of good wire with a plug at the end.

Heater Good Warmth - a prototype for many homemade devices

The work is carried out in stages:

Mix the glue with graphite powder and stir the resulting mixture thoroughly. Thus, we get not just an adhesive composition, but a graphite conductor with high resistance. The amount of graphite in the glue directly affects the maximum temperature of the future heater. On average it is about 65 °C.
Apply the prepared composition onto a sheet of plastic using zigzag wide strokes. For processing we use the rougher side of the sheet.
We connect the plastic sheets together using epoxy glue.
For greater structural strength, we construct a wooden frame that securely fixes the sheets.
We attach copper terminals to the graphite conductors on different sides of the structure. As an option, you can also connect a simple thermostat, which will allow you to set the most comfortable heating mode. However, this is not necessary.
Dry the structure thoroughly. Even slight humidity will damage the homemade heater the first time you try to turn it on.
We carry out tests and measure the resistance of the device. Based on the obtained value, we calculate the power and determine whether the heater can be safely connected to the network.

The device is ready for use. It can be placed on the floor or on the wall, does not take up much space, is quite effective and safe, provided it is well insulated.

Graphite is crushed and mixed with epoxy glue to create a graphite conductor.

Diagram of the future heating device

Method thirteen, well, this is really for extreme sports enthusiasts

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

A real oven in the car

So how? Did you 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 with a lot of boards.

If your car stalls in winter, don’t despair. Armed with any of the heaters listed above and having studied all the tips described, you will not freeze and survive in harsh weather conditions. Even if you find yourself in a car at night, face to face with a cold and harsh winter, you can create all the conditions in the cabin that are similar to the comfort of home. So, don't worry, 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 the range from +21...23 degrees Celsius. Low temperatures negatively affect concentration and alertness while driving, causing irritability. And safety is affected by driving with limited visibility due to icy windows.

If you have at least once had to get to your car in a parking lot in severe frosts or simply get into an icy car interior after leaving a warm home, then you know firsthand that this feeling is not a pleasant one. 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 solution, and it has long been known among motorists - an autonomous interior heater, which will happily provide comfort.

For nothing

Finally, there is a heater option that does not require any operating costs. If you live in a concrete house and the heating is weak, try, before buying or making a heater, placing sheets of foil insulation behind the radiators; it reflects back more than 80% of the IR, for which reinforced concrete is translucent. The removal of the sheet beyond the contour of the heating radiator is from 10 cm. The foil surface should face the room, and the plastic surface should face the wall. It is quite possible that a homemade reflector heater will be enough to establish a comfortable temperature in the apartment.

Working with pipes

After the oil heater circuit has been selected, it is necessary to manufacture its body. We make a drawing, determine the dimensions and start working with an angle grinder. The pipes are cut to length in the required quantity. After cleaning the ends, they are carefully and thoroughly welded. The performance of the 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 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 be of a different configuration.

The finished pipes are tied together. The piping is done with pipes, only of a smaller diameter. On the topmost 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 pipe with a coupling, one side of which will be welded. Using your plumbing and mechanical experience, the heater configuration can be made more aesthetically pleasing, unlike the one in the photo. By the way, the body can be not only tubular. Radiators from cars, old cast-iron radiators and other closed containers are well suited for this purpose.

Oil version

If you decide to make an oil heater strictly with your own hands, then be sure to arrange its reliable grounding. To fill it, use only high-quality transformer oil. The test version is only suitable for an empty concrete room.

To heat a large room, you need an apparatus with catalytic afterburning. It is very expensive.

Different craftsmen have their own way of answering this question. They created a do-it-yourself tent and camping heater with an afterburning function. True, this solution is not optimal for large rooms. But in hiking conditions it is optimal.

Variations of oil heating devices

Such an afterburner interacts with a camp stove. To create it, cans and car filters are used to make it easier to put in a tent. Then the operation of the device is based on gas fire.

A more advanced version of the afterburner has a mesh. This is a device made of steel. It has better efficiency and economy.

It is logical to combine these versions into one. It will work both from a burner and a candle.

Oil device diagram

If the device is rarely used, it can all be made from cans. You just need to put on a mesh cover.

Electric garage heating

The easiest way to heat a garage with electricity is to use a suitable heater, either purchased or homemade. If you don’t have the money to buy factory equipment, you can make it yourself. The simplest heating device is a goat heater, the most affordable, but also the most ineffective. It is done easily and simply - take some kind of non-flammable dielectric, and wrap a nichrome wire around it. Next, connect the electrical cable to the product and plug it into the outlet.

Among all the options for heating a garage, this option is considered the most dangerous - electricity is generally not a joke. Bare nichrome wire is used here, there is no insulation of any kind. Users may be burned or receive electric shock, and there is a risk of fire. It is prohibited to leave such heating unattended. And in general, you should not use such makeshift and extremely dangerous heaters.

Electric heating of the garage can be organized using factory heating devices:

Before you start choosing the type of heating, you should take care of at least minimal thermal insulation of the garage. Otherwise, the heat will simply go outside.

Heat guns - they are extremely safe and provide quick heat injection into the garage. It only takes a few minutes to warm up the entire volume, after which the room will become warm. Minus – increased noise level;
Infrared heaters are a modern solution that pleases with high efficiency. Infrared heating of the garage does not dry out the air and is not harmful to health. Simple IR heaters are used here, which heat not 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 a garage in winter and not have to worry about installing or manufacturing complex equipment;
Electric boilers - in this case, classic water heating using an electric boiler is organized in the garage. A boiler for a garage is selected according to its area and heat losses, focusing on the formula 1 kW of heat per 10 sq. m. area.

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

Permanent heating system

The best way to heat a garage is to connect it to a common circuit. This option makes sense if the garage is attached or is part of a building with common heating. In other cases, you need to make a separate heating and ventilation system.

When the task is to heat the room for a long time, it is better to choose gas and electric boilers. The gas heater is practical and easy to use, the fuel is available and inexpensive. But there is one caveat - you need to allocate space for the boiler room and connect to the gas main. Electric boilers are much safer, but such a heat source cannot be called cheap. It is for these reasons that motorhomes are less and less frequently drowned today.

You also need to remember about wood heating. At the moment, solid fuel is the most economical type. There are different options for such systems: pyrolysis combustion, home-made heaters, or all kinds of potbelly stoves and fireplaces. On sale you can find fully automated pellet boilers with fuel supply without human intervention.

It is difficult to choose which of the permanent heating systems will be more economical - when calculating, you need to take into account not only the price of purchasing and installing the equipment, but also think in advance how much the operation and raw materials will cost. It must be said that different heating systems are suitable for each region of our vast homeland. In places with an abundance of wood, the choice will fall on solid fuel units. In gasified areas, gas boilers and heat guns are most used.

If you don't spend much time in your garage, an electric heater might be the way to go. It does not require special installation skills. Even if such devices are resource-intensive, for heating for a short time this will be the best choice.

Classic electric heaters

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

Among the advantages of such devices are:

Ease of use.
Mobility and accessibility.
Good heating level.
Ability to control temperature.

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

radiators running on oil;
heat guns;
wall convectors;
fans and thermal curtains.

Each of them has its own positive and negative sides. It is not profitable to use such devices to regularly heat a 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 garage fires occur precisely because of a breakdown of the electric heater

We make ventilation with our own hands

To reduce the amount of moisture in the room, you can install one of 3 types of ventilation systems.

Forced

Here you need to use supply and exhaust fans. Requires access to electrical power. The installation algorithm is as follows:

Creating holes for hoods in the wall surface.
Installation of fans on inlet/outlet openings.
Connecting fans to the electrical network.

Natural

The algorithm for installing natural ventilation looks like this:

Purchase of ventilation pipes.
Making 2 holes in the wall surface. They must correspond to the radius of the pipe products.
Installation of pipes. The exhaust pipe should rise above the garage by 150 centimeters. The supply air should be directed towards the earth's surface.

Combined ventilation

It is a combination of forced and natural ventilation. Instead of 2 holes, you need to create 4. 2 of them need to be equipped with fans, and the remaining 2 will work naturally. The supply pipe must be installed at an angle, at a height of at least 0.2 meters from the floor surface.

Reviews about the heater "UFO ECO-C/23"

Most buyers chose this model precisely because of its compactness. Moreover, its design is simply magnificent. The presence of a thermostat also pleased many. In general, this model is suitable for almost everyone. One of the disadvantages is the lack of a tripod for installing an infrared heater on the floor. However, you can purchase it separately in any store. In this case, the device can be taken outside and used there. The special powder coating of the heater is not afraid of moisture, and this is very good.
