Few people in the construction of the garage provides for the possibility of heating. Therefore, in the process of operation of the room you have to heat yourself. Agree, buying heating appliances for periodic use is sometimes costly and impractical.
Some craftsmen make the unit with their own hands, using inexpensive materials. We suggest you familiarize yourself with the three most popular solutions for organizing individual heating.
Before you make a homemade heater for the garage, you need to understand the principle of operation of each unit, its device and study the assembly procedure.
General guidelines for creating devices
In an effort to save an expense item, many owners, choosing among the options for heaters, are in no hurry to purchase ready-made factory models.
After all, having a desire and possessing the appropriate skills, a heating device can always be constructed on its own.

When choosing a heater for the garage, which you can do yourself, many are guided by two parameters:
- The heating device should be easily activated, quickly warming up the room.
- The device should have a simple design, devoid of complex parts and elements.
- The operation of the device should be carried out at minimal financial cost.
All these requirements are met by the three options described below for homemade heaters that operate from different energy sources: gas, solid fuel and electricity.
The original and at the same time safe heater can be constructed even from improvised means used in the household
Equally important is the safety of the device. Therefore, regardless of the heating method in the garage, it is necessary to equip a ventilation system. After all, reducing the amount of oxygen and the accumulation of combustion products carries a risk to human life.
Homemade gas heater
The main advantage of this model is that its production requires a minimum of parts that can always be found in the economy of any craftsman.
Such an economical heating source is not too expensive; the costs of its manufacture and maintenance are fully bathed during operation
The only minus of the gas heater is the need to ensure adequate ventilation.
Preparation of materials and components
To make a gas heater in the garage, you need to prepare in advance:
- burner with valve;
- tin sheet;
- scissors for metal;
- drill with a thin drill;
- rivets;
- riveter.
For the manufacture of the lattice, a segment of a fine-mesh metal mesh will be required. Well, if you have at hand a regular wire strainer from a colander, it will act as a protective grill.
The main element of the device is a gas-filled collet spray with a capacity of 450 milliliters, used to refuel lighters
Collet cylinders are convenient in that when you use them, you can not immediately spend all the contents. The presence of shutoff valves allows you to use the device repeatedly.
If desired, the heating structure can be made on the basis of not only disposable cans used to refuel lighters, but also by using a small refilled cylinder.
Cutting blanks and assembling the structure
In the manufacture of the structure, the heater is first fixed to the burner.
The selected household sieve of the appropriate diameter is applied to the galvanized sheet and circled with a marker
Four rectangular ears are drawn in the direction of the four sides of the workpiece deposited on the galvanized sheet. One of the ears should be made twice as long as the rest. Workpieces are cut along the intended contour, trying to make smooth, barren-free sections.
The burner is bolted to the cut tin blank with bolts. The ears located on four sides of the billet are bent in the opposite direction and used to fix the strainer.
The strainer attached with the tin circle ears has a dome shape, so it will dissipate heat perfectly on the sides
To attach the second protective mesh, take another piece of sheet metal and cut out of it exactly the same size circle. Elongate the ears necessary for attaching the mesh are attached to the blank.
Having retreated from the edge of the circle by half a centimeter, 10 through holes are drilled along the circumference. From a cut of a fine-mesh metal mesh, a strip is cut whose length corresponds to the diameter of the cut tin blank.
The ears located on four sides are bent and used to fix the wide side of the strip of fine mesh, the second workpiece is fixed on the opposite side
The bent ears of the round tin blanks are fixed to opposite sides of the mesh strip with a riveter and rivets. When assembled, a cylinder with mesh walls and tin ends should be obtained.
The design, including two grids, is advantageous in that it has an increased heating surface and is equipped with additional protection.
At the final stage, it remains only to turn on the gas water heater and check its operability. The heat produced by this small device will be enough to warm a small room or garage.
Used cylinder potbelly stove
Potbelly stoves, popular a hundred years ago, today do not give up their positions, acting as the main source of heat in garages and utility rooms. And their main advantage is that they can work not only on wood, but also on everything that burns.
Potbelly stoves are made from gas cylinders containing up to 40–50 liters of propane to empty, pieces of steel pipes and thick-walled barrels with a small volume
The minimum wall thickness of such structures should be 2-3 mm, but still the best option is 5 cm, so any type of fuel can be used. If we compare the horizontal and vertical models, the first win in terms of ease of loading logs.
Vertical design
The simplest manufacturing option for a potbelly stove involves the use of a gas cylinder: the housing of the heating structure is already ready, it remains only to equip the compartments for filling the fuel and an ash pan. The height of the cylinder is about 850 mm, the diameter in girth is 300 mm, and a sufficient wall thickness allows you to use any type of fuel.
To build a vertically mounted structure, the cylinder is divided into two parts unequal in volume:
- top - occupies 2/3 of the structure acts as a receiving chamber for laying firewood;
- lower - occupies 1/3 of the structure and is used to collect ash.
For the manufacture of potbelly stoves in the wall of the container for the size of each of the two sections, holes are cut out for arranging the doors. The doors themselves can be constructed from a cut piece of a balloon wall or cut from sheet metal.
On the border between the upper and lower compartment, grates are mounted. But since it is difficult to find a finished cast-iron grate of a suitable size, thick rods are used for its manufacture.
The basis for the manufacture of grates is steel reinforcement 12-16 mm thick, the cut rods of which are placed at a distance of 2 cm from each other
A hole for a chimney with a diameter of at least 150 mm is cut out in the upper part of the cylinder. This element can be welded from a cut of sheet metal. The main thing is that the diameter of the pipe obtained corresponds to the size of the chimney in order to simplify the joining process.
Doors are equipped with locks and attached to the body by welding. If desired, loops can be made from several links of a thick steel chain.
Since the potbelly stove is not initially classified as a sealed heating system, there is no need to use gaskets
In order to block the gap formed around the door perimeter, it is better to weld a small side on the outside of the workpiece perimeter - a metal strip 1.5-2 cm wide. It remains only to connect the finished structure to the chimney and conduct tests.
Model with horizontal housing
With a horizontal arrangement of the casing, the ash collection compartment is welded from below the structure. The main compartment is designed for filling fuel and unloading burnt coal. It is equipped with a chimney pipe with a diameter of 10 cm.
It is fashionable to build an ash collecting compartment from a suitable channel size or to weld to a given size from a steel sheet cut
A hole is made in the side wall of the housing for installing the combustion door. Its size should not exceed the diameter of the chimney pipe. The door itself is equipped with a latch and mounted on hinges.
In the wall of the housing, which will be directed downward, make holes. They will perform the function of a grate.
To improve the heat transfer of a hot furnace, the chimney can be made in the form of an elongated broken structure. The main thing when arranging a chimney for a potbelly stove is to avoid horizontal sections. Some craftsmen, to improve the heating of the room, erect sheet metal casings around the cylinders.
But do not forget that the potbelly stove carries a potential danger. Therefore, the room where it will be installed should be aired periodically.

Production of a desktop fan heater
This type of device is a heater and a fan in one person. If desired, a homemade fan heater can be used as an impromptu air conditioner.
A heater located in the device’s case will provide heat in cold weather, and a computer cooler placed there will create a pleasant breeze in the hot months
This type of heater is convenient in that it allows you to adjust the heating temperature and the speed of rotation of the cooler.
Selection of required materials
To create a fan heater you will need the following materials:
- rheostat;
- switch;
- power connector;
- electric wire;
- LED Strip Light;
- 12-volt computer cooler;
- three-volt power supply for 12 volts;
To fix the heating element, two ten-centimeter rods of copper wire with a cross section of 1.5 sq. Mm will also be required.
The body of the device will be made of wooden blanks with a thickness of 9 mm, and the supporting legs - of a stick of the same material with a diameter of 12 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 emery paper will also be required to clean the wooden workpieces by removing the burrs along the edges.
Assembly of body parts
The future heater will be in the form of a cube. The body of the device is assembled from wooden boards 9 mm thick.
Need to cut:
- 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 1 * 1.5 cm in size.
For the manufacture of construction legs from a wooden stick D12 mm, 2 work pieces of 3 cm each are sawn off.
To generate heat freely outside the heater, holes with a diameter of 8-10 mm are drilled in square billets
To simplify your task, make paper patterns, the sizes of which correspond to the dimensions of the blanks 12x12 cm. Marking the location of holes is applied directly to the patterns. They are applied to each side and drilled through.
In the workpiece 10.2 * 10.2 cm, having maintained a distance of 2.5 cm from the edge, make a hole D7 mm. On the second workpiece of the same type, two of the same holes are made, having maintained a distance between them of 2.5 cm. On the third workpiece of 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, departing from the edge by 1.2 cm, make two holes of D12 mm, maintaining a distance between them of 7 cm.
To assemble the structure, square billets of 10.2x10.2 centimeters are glued to the lateral sides of a 10.2 x 12 cm rectangle
A square blank with a drilled hole of 9 cm is installed inside the housing. After that, the last rectangular piece is attached, closing the construction housing. 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 a spring is suitable, it is necessary to connect it to a 12-volt power supply and take measurements using a multimeter.
So to create a warm flow, it is enough if the multimeter reads 2.5 A. With these parameters, a power supply of 12 W will generate about 30 V of heat.
The selected spring is soldered to copper rods, the ends of which are fixed to workpieces with a size of 1x1.5 cm. The assembled structure is glued to the corners of the body. To the ends of the rods soldered bare "tails" of the electric cable. After that, a bar equipped with holes is attached.
To connect the cooler, the ends of the LED strip are soldered to the blue and red wires, then they are pulled out through a hole with a diameter of 5 mm
Having fixed the cooler inside the case, the same manipulations are performed with a rheostat, a switch and a power connector.
If all structural elements are connected correctly, then when the rheostat is turned on, the 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 that, the heater spring will begin to heat up.
The main condition for the operation of the device is that the spring only works when the cooler is on; otherwise it just burns out
The assembled structure from the outside can only be sanded and treated with wood wax, or varnished in 2-3 layers.
Thanks to the presentable appearance, such a heater can be safely used not only for heating the garage, but also in the arrangement of living rooms.
