With the onset of cold weather, it becomes necessary to heat the premises. It is not always possible to carry out central or autonomous heating to premises such as a garage, a barn, a corral, a greenhouse. The reasons may be different: lack of funds due to the high cost of connecting such systems or lack of technical capability.
If you make a gas heater with your own hands, then it will effectively heat the utility rooms. Now on the market you can choose and buy a wide variety of models of gas heaters at different prices and with different characteristics. However, the seller's biting mark-up is included in the price.

Homemade design features
The main task that the future self-made device will perform is heating the room, tent, garage and other premises. With self-assembly, the appearance of the device and its decorative qualities fade into the background.
And an important role will be played by the sufficiency of the amount of heat generated, the safety of operation and the ease of transportation of the device.
Lightweight, portable and easy-to-use structures made of gas burners do a good job of heating small spaces
For heating purposes, a variety of home-made gas structures are used. Making heaters from gas burners or gas stoves with your own hands is not difficult. For quick assembly, you will need a pre-prepared diagram, the material from which the heater will be made, and a variety of tools.
Often, a homemade gas heater is taken on a tourist trip out of town or on a fishing trip, on a variety of charges as a source of additional heat. In such cases, it will be enough to assemble the device, check its operability, inspect it for leaks and start heating directly.
Sometimes homemade heater it is planned to be used as an alternative heating source. For example, in a country house, in a barn, in a pen, in a garage and in other premises in order to save money on utility bills and on the purchase of gas equipment.
Often the prototype for the manufacture of mobile gas heaters are gas infrared burners and factory-made tiles.
In such cases, care must be taken to minimize heat loss within the heated room. This is done by insulating the outer and inner walls, floor and ceiling of the structure. It is most effective to carry out procedures for both internal and external insulation. Then the heat will keep as long as possible, and the gas consumption will be much reduced.
If it is not possible to carry out two types of insulation at the same time, then you need to insulate the building at least from the inside. It is more efficient. During the procedure, it is necessary to use a material suitable for thermal insulation, as well as refractory materials and coatings.
Insulation of a heated room significantly reduces heat loss. In such rooms, the heating device will not work in vain, and, therefore, the user will not spend extra money on buying gas.
When using gas equipment, you must always follow safety precautions and adhere to the rules for installing equipment and insulating premises. If the heated building is finished with refractory materials, then it will be fire resistant. This greatly reduces the risk of fire and unexpected fires.
It is best to place a homemade gas heater in the center of the heated room. In this case, the generated heat is not lost or absorbed by the walls, since there is no contact with them. Warm air will go up to the ceiling of the room. If you also install special reflectors on the ceilings, then the effect of a heat cap will be created in the room.
This positive phenomenon allows you to significantly save money on space heating using homemade gas structures. Warm air circulates throughout the space and does not leave it. It is worth knowing that the heat cap effect is created when the heater emits a sufficiently intense air flow.
The main quality that a self-made device should have is operational safety. If there is a leak when using the heater, immediately shut off the gas supply.
According to the assembly results, a homemade heating device should have the following parameters:
- safe and easy operation;
- economical consumption of energy resources, in this case gas;
- efficient and fast heating of premises;
- quick start of the device, the possibility of long-term operation;
- ease of assembly and ease of replacement of parts that are out of order;
- the ability to transport the device;
- sizes convenient for transfer, transportation and operation.
All of the above characteristics are rather difficult to fit into one structure. However, some craftsmen manage to independently make a gas heater of sufficient power, convenient, easy to use, which serves the user for a long time.
The advantages of homemade gas heaters include:
- Economical work. Sometimes one full cylinder can be enough for 12 hours of continuous operation of the device. Of course, it all depends on the size of the balloon.
- The ability to quickly turn on and off.
- Compact and lightweight. Some homemade constructions are convenient to take on hikes. They do not take up much space and weigh several kilograms. And the beneficial effect of their use is difficult to underestimate.
Among the disadvantages of homemade designs, the need for selection is highlighted suitable bottle or the presence of an adapter. Therefore, you need to take care of purchasing additional spray cans in advance. Or, be able to pour gas from a large cylinder into a small tank.
The heat exchanger is an important structural part of the heater. It is a steel box with welded pipes going through it. The heat exchanger is installed in a metal case. A fan is also mounted
Some self-made gas heaters cannot withstand severe freezing temperatures and will not start if the air temperature is below a certain mark. Facing such a problem can cloud a camping trip. However, in rooms, the temperature usually does not drop to very low levels.
If the heater is operated in an enclosed space, it is imperative that fresh air is supplied. It is also important to consider that the level of carbon dioxide in the room increases. Air humidity drops significantly.
Do not leave the switched on device unattended, and also bring flammable objects to it. This could lead to fire and fire.
The efficiency of a self-designed device is determined by its basic characteristics.
Efficiency. This indicator is determined by the ratio of the energy that is used for heating to the energy that is spent to generate it. Gas heaters have different efficiency values.
Instrument safety. Often, on self-made structures, the installation of devices that ensure safe operation is neglected: valves, sensors that automatically turn off the burner.
The operation of this device is as follows. The burner heats up the inner tubes. The air that enters from the outside is heated by the tubes and becomes hot at the exit. The exhaust pipe removes carbon dioxide from the room
Fuel consumption and area heated by the device. Fuel consumption also changes depending on the size of the device. The larger the room, the larger the burner will be required.
Gas heater device
All structures are united by a single gas supply system. As a fuel source, gas cylinders with propane-butane or other types of gas mixtures. Also for small heaters, gas cartridges are used for burners. They can be carefully refilled and poured with your own hands. The main thing is to observe safety precautions.
Many homemade gas heaters work according to the principle infrared radiation. It consists in the fact that the fuel gradually burns in the burner and thereby heats the heating element, which, in turn, releases heat in the infrared range. In this way, all items in the room or tent are heated. After that, the heat is released into the air.
Self-made gas heaters are quite diverse and can have different weights from a pound to a dozen kilograms. It all depends on the complexity of the design and the required level of heat generated at the outlet.
Many owners are wondering about finding a more budgetary alternative to traditional heating. Homemade installations are a great solution to the problem.
Usually homemade products are constructed from the following basic elements:
- fans that evenly distribute heated air throughout the room;
- a power regulator that allows you to adjust the level of heat generated and the temperature in the room;
- a gas burner that directly burns gas and heats the system;
- thermal emitter - an element that accumulates thermal energy and gives it to the air or to objects in the room;
- grilles that protect the heat radiator from direct contact with objects.
In addition to the main elements, additional ones will be required, which may include handles, grilles, reflectors, covers, fasteners, gas hoses and other blanks.
The device made in this way is suitable for heating small and medium rooms, and small rooms. At the same time, there is no need for electrical appliances and electricity. When the next cylinder is used up, you can refuel it or purchase a new one.
The main advantage of a homemade design is the ability to use inexpensive and affordable components. In addition, the assembly is consistent and simple.
Some homemade gas infrared heaters also perform additional functions, which include heating water, drying clothes and various items. Some devices can also be used to cook food. At night, such a heater glows and is a source of additional lighting.
Homemade appliance from a gas burner
By our proposed method, you can assemble a not very powerful, but convenient, compact, portable gas heater. Such a device is suitable for heating small rooms, a garage, a small greenhouse, basement or tent.
For the assembly of the structure, a primus gas burner is used. It is used for cooking. This scheme is also applicable when using collet valve cylinders.
Gas burners and stoves are connected to steel or composite gas cylinders. They work from any mixture of liquefied gases
In addition to the burner, you will need the following material at hand:
- tin sheet of a small area;
- round metal sieve;
- rivets.
You will also need some tools: an electric drill with a small drill, a riveting device and metal scissors.
The operation of homemade gas devices requires increased attention to detail from the user. User safety directly depends on whether safety measures are followed or not.
The assembly of the device is carried out as follows. First, you need to take a pre-prepared sheet of tin and attach a sieve to it. The sieve must be circled with a marker or construction pencil.
After that, a sieve is put aside and rectangular ears or the so-called scan are neatly drawn on top of the circle with a pencil with a ruler on the tin. One eyelet should be slightly longer than the remaining three.
Then you need to take scissors and carefully cut out the lined workpiece. It is important to cut the parts so that there are no irregularities on their surface.
Once the circle is cut from the sheet, it must be bolted to the torch. To do this, you need a drill, with which you carefully drill even holes. Then you need to trim the drilled holes and erase the rest of the metal with a file or cut (sharpen) with a grinder.
As a result, it is possible to assemble a heater with a vertically or horizontally located gas canister. It depends on the type of burner and on the collector's desire.
For the resulting structure, you need to bend the rectangular ears on top and attach a metal sieve. The main task of the sieve during the operation of the heater will be to dissipate heat. This design can be improved by the additional use of a mesh.
First of all, another circle with ears is cut out of the sheet metal. Its dimensions must match the dimensions of the first part. Then, using a drill, you need to drill holes in the cut out circle, which should be located a short distance from the edge of the workpiece. After that, you need to cut a small strip from the mesh.
The cut out narrow strip is attached above the sieve to the first and second tin circle by the ears using rivets. The ears should be bent at a 90 degree angle. As a result, the structure will resemble a metal cylinder.
After making such a gas heater with your own hands using a gas burner, the design must be checked. You need to make sure that it can be used safely. The gas cartridge is connected to the burner, the gas supply is switched on, the burner is ignited, and the device starts heating the room.
Using an adapter hose, you can connect such a burner to a large gas cylinder. Then you do not have to spend additional time replacing and refueling the container with gas. The cylinder must be installed gas reducer, which protects the structure from reverse gas movement and allows you to regulate the pressure.
It is convenient to pour gas from one container to another with similar hoses of homemade or factory production, as well as connect the heater to a gas source
It is worth remembering that manufacturers of gas cartridges do not recommend reusing their products and refuel cans.
Using a similar approach, you can design a larger homemade gas heater. Such devices will already resemble gas stoves and can be powered directly from a gas pipe or a large cylinder. Naturally, the power of such a furnace is enough to heat a larger room.
However, such structures are not so easy to move from one place to another, they take up a lot of space and often require additional construction of a chimney and a ventilation system.
Portable tile heater
Small rooms, garage, greenhouse, tent can be conveniently heated with a portable desktop gas heater. Such a device is constructed from a rectangular flat tile equipped with a metal grill.
The collection of this device involves attaching a part of a 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 provides 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 scheme 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. It is necessary to take accurate measurements from the quadrangular tile using a ruler or tape measure. This is required to determine the parameters of the heater body. After taking measurements, you need to cut out the blanks from the sheet metal with scissors. Further, the workpieces are fastened with rivets into the casing.
Then the casing is fixed with hooks on the tile. In order for it to be quickly removed and mounted back, you need to make a movable bar. It is easy to make such a bar using a small spring that is connected to the lift arm.
Thanks to this solution, in the future it will be possible to easily remove the cover for cleaning or transport. The homemade scheme under consideration assumes the presence of a special ventilation system. To install it, you will need a banal fan without any additional complex devices or materials.
You can also purchase a ceramic infrared burner instead of a tile. The infrared heating system provides for 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 shaping and resizing the fan blades takes about half an hour. After carrying out these steps, you need to install a ready-made fan behind the heater case so that there is a draft inside the case.
You also need to install a metal combustion chamber. The combustion chamber housing needs to be dotted with many small holes. They can be done with an electric drill and metal drill or with a hammer and nail. The holes should be at a short distance from each other.
It is also necessary to purchase a rubber hose with an adapter for connecting flat tiles to gas pipe or a gas bottle. 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 up the heat radiator, which gives off heat energy to the room. At night, such a heater illuminates a small area around itself.
Such a home-made gas heater copes well with the task of heating a room not only in the autumn-spring period, but even in the winter season. Also, such a device is economical in gas consumption and has a high efficiency.
Construction of a heater from a pipe
This homemade construction is also called heat gas cannon. It generates significantly more heat than previous heaters and absorbs more energy resources. Also, such structures are often equipped with chimneys, which makes them cumbersome and difficult to carry.
The diagram will acquaint you with the principle of operation and design features of the gas heat gun. The heat flux generated by the appliance is distributed by a fan
To assemble the heater yourself, you need to collect the following material:
- three meter pipes of various diameters (two 8 cm and one 18 cm);
- steel plates with which fastening will be carried out;
- Metal sheet;
- gas burner with piezo ignition;
- axial fan.
You will also need a variety of tools: a drill, a welding machine, a tape measure, a level, a grinder, metal scissors. The pipes can be replaced with cylinders or fire extinguishers of suitable diameters. The grinder is needed to cut the bottom and top, as well as shorten the workpieces.
Working in intensive mode, a forty-liter cylinder is enough for heating a room with an area of 15 square meters for about a week. While working, the cannon dries the air, so you need to humidify it.
In a pipe with a diameter of 18 cm, two holes of different diameters are drilled: 1 cm and 8 cm. You need to drill them opposite each other.
A 30 cm segment is cut from a pipe with a diameter of 8 cm, which will represent the combustion chamber. Fasteners are welded to this pipe and a hole with a diameter of 1 cm is drilled in it. This pipe is then inserted into the first pipe.
A plug must be cut out of a sheet of metal. It will close the gap between the heater body and the combustion chamber. The combustion chamber is welded to the body, and a branch pipe for the output of hot air is welded to the hole with a diameter of 8 cm. After that, the plug is welded. After making sure that the gas burner is firmly attached to the combustion chamber, you can push the hose through the centimeter holes.
A fan is installed at the back of the device, and a chimney is installed on top. In order for the heater to stand steadily on the surface, the legs should be welded. The gas heat gun effectively heats the premises and uses gas economically. However, when using it, you should adhere to safety precautions.

Homemade infrared gas heater:
Anyone can assemble a gas heater according to the considered schemes of the house. You just need to follow safety precautions and do not neglect the instructions for putting the devices into operation. If you assemble the heater yourself, you can save money. In addition, the efficiency and performance of such devices is not inferior to store-bought ones.
If you intend to heat a small room or tent, as well as take the device on trips and hikes, then it is better to make the heater from a gas burner or from a gas stove. They are more compact, take up less space and are easy to transport. Hot gas cannons are suitable for heating larger rooms, generate more heat and require an electrical connection to operate the fan.
