Thermal gas gun: the specificity of the equipment and the rules of use
This article discusses in detail the features and technical characteristics of such heating equipment as a thermal gas gun: the principle of operation and the internal structure of the structure, the main varieties and rules of use in residential premises and garage. The text contains recommendations for making the device with your own hands.
Gas heat guns have a number of advantages over diesel and electric analogues
Thermal gas gun: principle of operation and classification of structures
In rooms where there is no centralized heating system in winter, it is quite difficult to maintain an optimal microclimate for people to live in. Therefore, most owners of country and private houses prefer to buy a gas gun for heating the premises. This type of equipment has a high efficiency index, while the consumption of electrical energy is minimal.
Due to the almost complete combustion of fuel, the efficiency of gas guns is approaching almost 100%
In fact, such a gun is a heat fan that runs on gas. These designs have many advantages. Among the most significant advantages are the affordable price of gas cannons on bottled gas, their mobility, as well as a simple operating system.
The demand for these modern generation heaters increases during the heating season if there is no centralized heating system or it does not work well enough. The design releases warm air into the room, which is formed due to the combustion of fuel – gas.
The unit is enclosed in a metal housing with outlets designed for hot air. The shape of the gun is streamlined, the following elements are inside it:
- fan;
- burner;
- control device;
- heat exchanger;
- a device that provides ignition;
- the thermostat.

In addition, there may be additional components in the case, which depend on the model and design features.
Varieties of gas guns for heating rooms
The popularity of gas guns is due to their practicality and wide scope of application. These units are used not only for heating, but also for ventilation of rooms, as well as drying objects with large dimensions. Despite the large assortment, there are only two types of structures: gas heat guns of indirect heating and direct.
Pay attention! During the operation of the gun, there is an inevitable burnout of oxygen. For this reason, it is not recommended to use them in rooms where there is no ventilation system. It can be life-threatening.
Direct heating structures do not have the function of purifying air flows from burning, so they can poison oxygen in residential premises. This is the only drawback of such units. Direct heating guns have a 100% efficiency and operate using a minimum amount of fuel and electrical energy.
The design of the direct heating gas gun is quite simple: inside the housing there is a fan and a burner that heats the air, and the fan blows it into the room, creating a powerful airflow
In indirect heating gas guns, a ring-type heat exchanger is used as a heating element. The principle of operation of these devices differs from the previous version in that the fuel is first burned in the design, and then the toxic products that were released as a result of this process.
Indirect-acting gas guns belong to the category of environmentally friendly devices. For this reason, there are no restrictions regarding their operation. It is allowed to install indirect heating guns in rooms where ventilation is limited. The designs have only one significant drawback. The case is equipped with a chimney, which significantly affects the mobility of these devices, as well as complicates their transportation.
The principle of operation of a gas heat gun for residential premises
Before going to the store to buy a gas gun for heating a living room, it is worth studying in detail the principle of operation of such units, their internal structure and other parameters.
The principle of operation of a thermal gas gun
The gas gun works according to this principle:
When the air in the room warms up to a certain level, the thermostat is triggered. At this moment, the switch breaks the electrical circuit, and the device stops working. This principle of operation allows you to control the temperature in the room and maintain an optimal microclimate.
The specificity of a low-pressure natural gas gun
Heaters are most often used for household needs. Moreover, most buyers, choosing the optimal device, will prefer to buy a gas heat gun of indirect heating with a mobile design, which is equipped with control knobs and wheels.
The complete absence of harmful substances in the combustion products make gas guns especially effective for use in greenhouses and greenhouses
Stationary models have a gas cylinder, which creates difficulties when moving. The technical characteristics of the gun, as well as the duration of its operation, depend on the volume of this tank. Models with a stationary design are considered obsolete because they are less practical than mobile versions.
Pay attention! Compact models of guns running on natural gas are very economical. The consumption of the unit is only 1 l/h.
The heat gun is an independent heating device. At the same time, it can play the role of a structural element of an entire installation designed to maintain the necessary microclimate in the room. Structures running on natural gas can be used for heating specialized and automotive equipment.
The capabilities of this equipment will be useful in the repair process and even when installing stretch ceilings. The fan present in the design accelerates the processes. Air flow heating is controlled by a built-in temperature controller.
One of the most economical ways to heat a room is to directly heat the room air by burning natural gas
Why experts advise to buy a gas heat gun: the scope of the devices
This type of equipment, such as a gas gun, is in demand not only in everyday life, but also in production. The scope of application extends to the heating of residential and non-residential premises. The guns are used for drying individual components that have a production and automotive direction.
In addition, the functionality of gas equipment will be useful in large areas, the size of which exceeds 25 m2.
Features of operation of indirect gas heat guns for garage
Non-residential premises collect dampness, which negatively affects storage. Such premises include a garage. Increased humidity has a bad effect on a vehicle that has been in it for a long time. To remove dampness from the walls, as well as get rid of the fungus, experts recommend buying a gas gun for the garage. The cost of such units is quite high, but the versatility of such structures justifies the costs, since they can also be used in the country and at home for rapid heating.
A gas gun for a garage is a mobile device that, depending on the size, can either be moved or rolled to another place
The power of the heating devices is in the range of 10-100 kW. If there is no ventilation system in the room, the efficiency of the gas heat gun for the garage is reduced to zero. It is impossible to stay in a room with a working device for a long time, and as a result of constantly opening the gate for the sake of ventilation, all the injected heat will simply go outside.
The use of a heat gun in the garage will create conditions for the normal start of the car engine, as well as the performance of repair work in the winter season.
In a heated room, any processes are greatly simplified and accelerated:
- sorting tools;
- wiping the car body and windows;
- interior cleaning, etc.
A gas heat gun for a garage is the optimal choice in terms of power, efficiency and speed of heating the room
To choose a device with optimal characteristics, you need to consider the following points:
- the material from which the garage is built (brick, stone or metal);
- the quality of thermal insulation (types and features of internal and external insulation);
- absence or presence of electrical wiring in the room (the gun will not be able to work without electricity);
- features of the ventilation system;
- total area of the room;
- operations that are carried out in the garage.
Pay attention! After using the device, the room must be ventilated for at least 10 minutes.
Features of operation of a gas gun for room heating
There are two types of devices for heating rooms. Some of them consume liquefied gas. Butane or propane can be used in such constructions. Other types of gas guns for heating are universal. Their housing has a built-in component that provides pressure stabilization. The presence of this device allows you to connect the equipment directly to the gas pipeline.
Since during gorenje a large volume of carbon monoxide (CO) is emitted into the atmosphere, which is deadly to humans in high concentrations, the heated room must necessarily have a good ventilation system
Depending on what type of fuel is consumed by the device, it may have different characteristics. The network gas pressure varies between 0.015-0.02 MPa. Therefore, the guns are designed for different input pressure indicators. At the same time, the gas cylinder reducer has a value of 0.036 MPa at the outlet.
The differences between the models also affect the nozzles, which may have different nozzle diameters. This design feature is due to the composition of the fuel. The caloric content of liquefied and natural gas differ significantly. The balloon version of the fuel is three times more calorific than what is supplied by the highway. For this reason, it is not allowed to use natural gas as a substitute for liquefied fuel, if the design of the gun does not provide for such a possibility. This information is prescribed by the manufacturer in the instructions that are attached to the device.

How to make a gas heat gun with your own hands
In most cases, the heat gun is used by craftsmen as a heating device for the garage. Therefore, it would be more expedient to make an indirect heating design that connects to the chimney system and allows you to stay indoors during its operation.
To make a gun , you will need:
- two pipes with a length of 1 m and a diameter of 18 cm (housing) and 8 cm (combustion chamber);
- pipe with a diameter of 8 cm and a length of 30 cm (outlet pipe);
- axial type fan with round flange;
- the burner is gas, equipped with a piezoelectric element.
The design of the gas gun is quite simple, so it will not be difficult for anyone to make the device
The technology of assembling a gas gun with your own hands
Before you start assembling the gun, you need to take care of the availability of the scheme. It will serve as a guide in the process of work. First you need to take a pipe with a large diameter and make a couple of holes. The size of one of them is 8 cm . An outlet pipe for heated air will be attached to this hole. The size of the second one is 1 cm . This hole will be used to fix the gas hose. A combustion chamber must be made from a pipe with a diameter of 8 cm.
Useful advice! In order for the combustion chamber to be rigidly held in the central part of the housing, it is desirable to use plates that are welded to the pipe.
Next, the plug is prepared. It can be cut from a metal sheet. This element must cover the gap between the body part and the combustion chamber. At the same time, it is very important not to block access so that it is possible to connect the structure to the chimney.
Diagram of a thermal gas gun
At the next stage, all the elements of the gas gun are assembled together. This will require a welding machine and the skills to handle it. The combustion chamber, together with the stiffeners, is welded inside a large pipe. The pipe and plug are fixed from the outside. Through this element, the heated air will flow into the room. It remains to install a gas burner and a fan. All elements must be firmly fixed.
The process of assembling a structure with direct heating is much simpler. Such a gun consists of a pipe, at one end of which a fan and a burner are fixed. Gorenje products and hot air flows in this case will come out from the opposite side.
Rules for the safe operation of a heat gun
The gas-powered heat gun is very easy to use. If you follow the rules of its operation, this device will not pose any danger to human life or health.
Thanks to the multi-stage safety system, gas heat guns are absolutely reliable and easy to operate
Rules for safe operation:
Gas is much heavier than air, so it can accumulate in the lower part of the room, creating an explosive situation. For this reason, it is forbidden to use the cannon in rooms that are below ground level.
For the safe use of a gas gun, quality, a combination of technical and ergonomic properties play an important role
Gas-fired heat guns are designed for domestic and commercial use. They are easy to operate and economical. Such installations can be an excellent alternative to the standard method of heating. The assortment of modern stores includes a large number of modifications with various technical characteristics. Thanks to this, buyers can choose the optimal design for heating compact-sized premises, for example, a garage or a living room, and large-area spaces (shopping malls, airports, railway stations).
