In particular, a gas gun is actively used for heating rooms, which has sufficient potential to maintain optimal temperature regime vast space. But such a unit must be chosen wisely, focusing on technical characteristics and scope of application, otherwise it will not bring the expected effect. Moreover, you will have to choose between:
If a facility is just being built and it is necessary to ensure drying of the walls and maintain normal conditions for construction crews working in the premises, then gas heat guns using natural gas will be quite suitable, as well as diesel models.
What should you consider if you decide to choose a gas heat gun? These are the possibilities of this equipment and its technical parameters. The advantages of such units include:
So a gas gun for heating rooms can be quite suitable as an environmentally friendly and efficient equipment. Natural gas, which is used for such devices, is able to burn without residue and provide absolute efficiency. Operation of this equipment is possible both from gas pipelines and from portable cylinders.
If you read gas guns for space heating reviews, some users do not quite understand how such units work, which significantly complicates repair work if such a need arises.
Liquefied fuel is supplied to a special chamber, where it is atomized and mixed with air masses. And if you plan to repair master gas guns, then you need to check the ignition system, which is based on a piezoelectric element; it is this element that makes this type of equipment independent of external energy sources.
When an indirect heating gas gun is selected, all combustion products generated during operation will have to be forced out, and a dangerous concentration of toxic elements will not arise in the room. Such equipment can be used to heat residential premises, and the process can take place in a constant mode.
We can consider these to be the best gas heat guns in terms of safety. They have closed chambers in which the combustion process of natural gas occurs, and waste materials are discharged through a special pipe.
But there is one negative factor These units have a high cost. And if you analyze the gas heat gun Interskol TPG 30 reviews, it turns out that such equipment is not available to everyone, and repairs are too expensive.
Direct heating is produced by an open burner, and the combustion chamber is not closed, so that heat and combustion products enter the room. And this factor makes the use of such devices in residential premises dangerous. But you can always repair a gas gun with your own hands if it is direct-acting, since the design of such equipment is much simpler.

As part of our reviews, we have already looked at high-performance heat guns that run on liquid fuel. They have high efficiency, but are sources of unpleasant odors, since the fuel in them does not burn 100%. An alternative to them are gas units running on natural or liquefied gas (most often liquefied gas is used - a little later we will explain what this is connected with).
A gas gun for heating rooms is a relatively simple unit in terms of internal arrangement, using gas for its power supply. By burning the incoming fuel, this unit produces a large number of heat that is sent into the room using a powerful fan. The heart of the device is a burner with an ignition system - simple piezoelectric elements and electric ignition systems with electrodes are used here.
The device of a gas gun is as follows:
Some models of gas heat guns also contain heat exchangers - they serve to safely transfer heat to heated buildings and rooms.
A gas gun cannot work without electricity, since its essence is to “shoot” heat under high pressure, characterized by high productivity. Without a fan, it would turn into a very simple burner, which cannot boast of high efficiency. Therefore, it is almost impossible to find units that can operate in a completely autonomous mode - a power source is required here.
The gas heat gun is enclosed in a durable metal casing and its appearance really resembles some kind of weapon that fires cannonballs. Only instead of cannonballs, hot air flies out of its mouth. Due to the built-in fan, heated air masses are evenly distributed throughout the heated volume. Models with a thermostat monitor the temperature generated, providing precise temperature control.
To power gas heat guns for residential premises, two types of fuel are used - main gas or liquefied gas from a cylinder. In the first case, everything is not so simple, because to connect to the highway you need permission. Therefore, liquefied fuel is most often used to power the units. The gas cylinder for a heat gun is the same cylinder that is used in conjunction with conventional kitchen stoves. Its volume is not limited in any way; connection to the heat guns is carried out through a reducer to reduce the pressure.
Heat guns are most often used for heating non-residential premises - these can be various hangars, production workshops, buildings under renovation and warehouses. At the same time, people may be there at the time of work if adequate ventilation has been provided. As for residential premises, here they are used much less often - after all, less bulky and more accurate heating devices with a low noise level are more suitable for living rooms.
In residential premises, thermal gas guns can be used during repair and finishing work. They are used to dry the plaster and increase the temperature for faster drying. concrete screeds. They are also used during installation suspended ceilings– here we need comparatively heat required to tension the web. And thanks to the directed heat flow, builders have the opportunity to carry out spot drying.
All these units are divided into two large categories - with direct heating and with indirect heating.
As we have already said, gas heat guns are powered by a gas cylinder (mostly). The startup process looks like this:
The fan will turn on, the igniter will work (in some models the gas is ignited by a button with a piezoelectric element) - and after a few seconds, the room will begin to fill with warm air.
Let's see what are the pros and cons of gas heat guns for heating residential and non-residential premises. Let's start with the positive features:
Negative features:
Nevertheless, gas heat guns continue to be in demand equipment, especially in the construction industry.
If you are going to buy a gas heat gun, focus on its performance and power, comparing these parameters with the heated volume. Remember that for every 10 sq. m area requires at least 1 kW of heat. If you plan to use the unit for construction purposes, for drying plaster or installing suspended ceilings, you should choose a more powerful model.
Remember that the greater the power, the greater the noise level and the greater the gas consumption. If the task is to heat a small basement, cellar or greenhouse with a heat gun, choose small-sized models - they are somewhat similar to ordinary fans. To heat large hangars and warehouses, more efficient units will be needed. If people work in the premises and there is no ventilation, take a closer look at indirect heating heat guns.
Another selection criterion is the manufacturer. If you choose between domestic devices and foreign ones, then you won’t be able to give someone special preference. Russian and foreign brands make good gas heat guns, characterized by endurance and good technical characteristics. But if we look at the ratings, they are headed by the Master brand.
Enough theory - let's move on to practice. Now we will look at the most popular models of gas heat guns. All of them are direct heating models.
In order to extend the service life of the unit, the manufacturer has equipped it with overheating protection. As soon as certain indicators are exceeded, the equipment will turn off the gas supply and resume it after cooling. The heat gun also provides protection for the body from corrosion - for this purpose the body is coated with a special coating. The heat gun is unpretentious in operation and economical - it burns only 2.27 kg of gas fuel per hour.
There is no electric ignition here; a simple piezoelectric element is responsible for this. The heat gun is also equipped with overheating protection.
The heat gun turned out to be compact - its dimensions are 435x230x305 mm. This is an excellent choice for construction crews and anyone else who needs a portable gas heater with decent performance. The official price from the manufacturer is 4,499 rubles, which makes this heat gun one of the most affordable devices.

Demand for such modern unit increases significantly during the heating season in the absence of central heating or its poor-quality supply. Gas heating guns emit warm air, which is formed by burning gas. Externally, it is a streamlined metal body with a hole for the hot flow to escape, but inside the design is somewhat complicated and is represented by the following elements:
Before making the final choice, it is important to find out what types of designs exist and which option is optimal in a particular case. The gas heat gun is very popular; it is necessary for heating and ventilating residential premises and drying large objects. The range is wide, but the classification provides only two design features - direct and indirect heating. Both options are suitable for household needs, but have different appearance and operating principles.
In this design, air flows are not purified from burning, so they all collect in the living room and poison oxygen. Directly heated gas guns are needed where there is sufficient natural or artificial ventilation. This is the main disadvantage of the gun, but significant advantages remain 100% efficiency, minimal energy and fuel consumption.
The ring heat exchanger acts as the main heating element, which operates on the following principle: first the gas is burned, then the toxic products that are released during the formation of the fuel. An indirectly heated gas heat gun is an environmentally friendly device, so its installation indoors is possible even with limited ventilation. The disadvantage of the mechanism is the presence chimney, which complicates the mobility and transportation of a gas-type gun.
Before using the gun in home environment, it is necessary to understand in detail how it is structured, how it functions correctly, which manufacturer is the best in a given direction. This significantly facilitates the final selection of a suitable design and simplifies the operation process. The operating principle of a gas gun is as follows:
Such a home heater is used for domestic needs, and the preference of modern buyers is given to mobile types of gas “burner” with wheels and control knobs. Stationary guns are equipped with a gas cylinder, which is problematic to transport. The duration of operation of the unit itself and its technical characteristics depend on its volume. This stationary design of an indirect blow gas gun is considered obsolete and impractical to use; mobile models in the range are more in demand.
This is an independent heating device and a structural component of the heating installation, necessary to maintain the necessary climatic conditions in residential premises and beyond. A natural gas heat gun can be used to heat automobiles and special equipment, and is useful during repairs and for installing suspended ceilings. The presence of a fan allows you to speed up the technological process, and the built-in thermostat controls the heating of the air flow. The gun runs on gas, suitable model can be ordered in the online store.
It is also called a loudspeaker because you can hear a loud bang during operation. If the previous model operates on gas, then this unit has its own design features. A propane heat gun is an environmentally friendly device and is often used to scare away birds and wild animals. Among the advantages, experts highlight simplicity of design, lightness and efficiency.
Such gas-powered equipment is in demand in everyday life and in production and has found widespread use among the masses. This is not only quick heating of residential and non-residential premises, but also drying of individual items for automotive and industrial purposes. In addition, the use of a gas gun is appropriate for large areas - from 25 square meters. meters, in progress repair work, for example, when installing suspended ceilings.
These non-residential premises are characterized by dampness, which only hinders the storage and safety of a personal vehicle. To dry the walls and remove fungus from the far corners, it is recommended to use gas guns for the garage. The purchase is not cheap, but the unit can additionally be used at home and in the country. It is important to take into account such parameters as the size of the garage, the quality of thermal insulation, the mode of presence of people in such non-residential premises. There are two options for choosing guns:
Considering the comparative characteristics described above, it becomes obvious that stationary direct airflow structures are not suitable for heating the specified space. A gas heat gun for residential premises must be equipped with an exhaust pipe so that combustion products do not linger in the living room. In addition, it is important to obtain high efficiency with minimal energy consumption.
When carrying out repair work, this unit is also necessary. A gas heat gun for installing suspended ceilings is an indispensable “tool” because when PVC film is heated to 65 degrees over the entire surface, it becomes elastic and pliable. The material easily lies on the ceiling and is firmly attached to pre-prepared gaps. If the gas gun is turned on when performing this type of work, condensation does not accumulate on the base plate while attaching the PVC film. This is one of the important advantages of the participation of the mechanism during repair work.
If a person is superficially aware of how to turn on and off the specified mechanism, this does not mean that he is perfectly familiar with the use of heat guns. The principle of operation and operating rules can be studied in the instructions; if necessary, use the help of a specialist. When using a stationary gun, the following rules must be observed:
The most difficult thing is to make a choice, since the catalogs contain a huge number of items interesting design with unique technical characteristics. In order to buy a gas gun and not make a mistake, it is important to compare with electric and diesel designs. Some people prefer electric guns, where the main heating element is a heating element or a cylindrical spiral. However, it is important to understand the uneconomical nature of such a purchase for the future. Below are rated gas guns that have proven their effectiveness and cost-effectiveness of use.
Ballu Industrial Group brand products are professional heat generators that do not require installation. All guns are mobile, and with the help of a special handle they can be easily and quickly transported. Photos of such cylindrical models can be found on numerous websites on the Internet, but before purchasing, measure the area of the heated room and do not save on such an important purchase. Below are a few guns that were of particular interest to buyers:
The second model of the same manufacturer, no less popular among the masses, is presented below:
The models presented below are from different manufacturers, but have an identical cylindrical shape. Such heat guns are especially convenient for everyday use, are easy to transport, and do not take up much space. The original design does not interfere with the performance of basic functions; the main thing is not to clutter the outlets. Here are some great deals for your household needs:
The second gas gun is also in noticeable demand, but in terms of parameters it is a more powerful unit, therefore the electricity consumption is somewhat higher. This:
Indirectly heated gas guns are more often purchased because one of the advantages is environmentally friendly operation and the absence of toxic combustion products in the air. Direct heating positions are also in demand, but they are purchased in the presence of high-quality ventilation and in the case of an unhindered supply of oxygen in unlimited quantities. Here are interesting offers for household needs:
The second indirect heating gas gun and its brief technical characteristics are presented below:
This is a determining criterion for selection, on which the rate of heating of the room and energy consumption depend. For domestic purposes, 10 kW is enough, but for large areas it is better to turn your attention to maximum limit power 30 kW. Here are two proposals that domestic market are considered “running”:
A competitor in terms of power is the following products from a domestic manufacturer of gas guns:
Many buyers choose a gas gun based on the heating area, and to do this, the first thing they do is measure the room. This is a mandatory condition, otherwise the purchase will end up being completely useless. Gas structures on sale are standard, so all that remains is to decide on the company and your final choice. So:
Here is the second gas gun, which has a shorter range, but also has a faster heating time, minimal costs electricity:
For individual buyers, the dimensions of the structure are important so that the unit does not take up much space in the room and does not turn out to be unnecessarily bulky. The parameters are standard for domestic purposes, but there are more compact options for convenient storage. This:
An example of another compact gas gun is presented below:
Anna, 35 years old At first she heated the dacha with bottled gas, then bought a potbelly stove with a ceramic plate. It was still cold. A friend recommended the heat gun and took the Kraton for 4,000 rubles. It heats perfectly, I have no complaints, I no longer suffer from drafts in my dacha.
Marina, 39 years old In our house, instead of main heating, we have a Heat stream 40-GFA-E gas gun. For a room of 75 square meters is ideal. We bought it several years ago, it cost 5,000 rubles. It saves energy and distributes heat evenly. Everyone was happy.

The first thing you need to know when choosing best representative of this type of units - the internal structure of the heat gun and the features of its operation. Externally, the hero of our review is a cylinder located on a stand with wheels. The most important elements are hidden inside the case: a fuel supply system (conventional or liquefied gas), a special fan, a thermostat and gas-burner. The rest is free inner space called the combustion chamber. Also a necessary component located directly on the housing or on the transport stand.
NOTE! (click to find out)
Heating of the room is achieved through the following sequential actions of the gun:
Despite the apparent simplicity of the design, the technology we are considering has several subtypes that differ in heating technology. Let's look at each of them in detail.
This modification of a natural gas gun uses an open flame (as in a gas stove burner). Despite good level Efficiency and fast heating, harmful components formed during the combustion process also enter the room. In connection with this fact, the use of such a device for heating residential premises is strictly not recommended - fresh oxygen in such conditions will be negligible.
Unlike its non-ecological and unsafe “competitor,” such a model will simplify the owner’s life, preserving his health and indoor microclimate. This is accomplished by adding a chimney to the design, through which all negative components are discharged outside the working area. But there is also a “fly in the ointment” - indirectly heated gas guns have a high cost and a very limited presence in the domestic market, as well as increased dimensions, which complicate transportation.
Having understood some theoretical foundations, we suggest deciding on the areas of application of this equipment. This is necessary to know, since a heat gun using natural or liquefied gas is not suitable for every homeowner or entrepreneur:
NOTE! (click to find out)
Another important point in choosing a heat gun that runs on gas fuel is the preliminary calculation of the power for the room to be heated. To correctly calculate the characteristic, the following formula is used:
Q = V × ΔT × k , Where:
V– room volume, m³;
ΔT– the difference between the temperature outside and your desired temperature in the room, °C;
k– coefficient of thermal insulation of the building (from 0.6 to 4, depending on the design of the walls).
Inexperienced users often have many questions related to the correct connection and startup of equipment. There is nothing reprehensible in this, since gas is highly explosive, and in combination with electricity it is truly an “explosive mixture.” Anticipating similar situations, our editors invite you to learn how to perform such a procedure competently, efficiently and safely.
| Description of actions | Illustration |
| We attach the reducer and hose included with the device to the gas cylinder or main pipe. We connect the second end of the hose to the heat gun. |  |
| We find an available source of electricity and connect our unit to the network. |  |
| We turn on the device by pressing the buttons (may be called “Start”, “Start”, etc., depending on the model). We regulate the temperature on the remote panel, setting the required value. |  |
You are just a few steps away from purchasing a gas gun! But we recommend that you wait a little longer and listen to several recommendations that simplify the choice and further operation:
Unfortunately, we live in difficult times, when in most Russian families every penny counts. But due to this, more and more bright minds are appearing among the people who invent truly amazing things from scrap objects. “Is there really a homemade gas gun?” - the surprised readers of our article will ask. In response to the question posed, the editors Techno.guru invites you to watch a video from one talented “Kulibin”. We think it will be much clearer than a thousand words!
Before you firmly say “Yes” to purchasing a heat gun for a summer house, garage or construction site, let’s dot all the i’s by defining the advantages and disadvantages of the equipment we are considering.
| Advantages | Flaws |
| Profitable energy resource - gas is much cheaper different types liquid fuel. | Dependency on electricity - without “stable 220 Volts” the gun will not work. |
| A wide range of sizes - from compact mini-heat guns to huge industrial models. | Samples with direct air heating are harmful to the environment and human health. |
| High level of efficiency compared to diesel or electric modifications. | The devices increase the risk of fire, especially when operated by careless owners. |
| Increased mobility when using a liquefied gas cylinder. | A labor-intensive procedure for connecting a hose to the main pipe (almost never used in private practice). |

Classic heaters will not be able to provide heat to a room the way a gas heat gun can. It very quickly increases the air temperature in almost any room - residential, utility, warehouse, etc. Manufacturers offer many models that can satisfy the tastes of all customers.
Feel positive effect from the equipment it will be possible literally in a matter of minutes if you run the device at maximum power. Such a device is powered by gas, and a heat fan provides circulation to the heated air. Due to its high efficiency, a gas gun for heating rooms is an economical way to increase the temperature.
The demand for high-quality heating systems increases significantly closer to the beginning of autumn. Not always timely switching on of centralized heating or some breakdowns with it can delay the onset of the heating season. A heat gun will be very appropriate for such a case.
It can also act as auxiliary equipment during construction or repair. The hot air flow ensures rapid evaporation of moisture from almost any surface. The heated flow is obtained as a result of combustion of gas supplied from a cylinder or from a centralized network.
The equipment can operate on both main and bottled fuel
The device is a relatively small cylindrical device with a streamlined, protected body. The front part is equipped with a protective mesh through which a heated air stream is directed. The gas heat gun also has the following components:
To do right choice When choosing the optimal gas heater, you should familiarize yourself with the samples offered in online stores or construction supermarkets. The products can meet the needs of both small rooms and large buildings with large internal cubic capacity.
With all the variety of manufacturers, gas heat guns for residential premises are available in two versions: direct and indirect heating.
Equipment belonging to each of these groups is available for use in domestic and industrial conditions. The difference lies in appearance and function.
A direct heating heater does not have high-quality filtration that can clean the output stream from soot and soot. They quickly burn out oxygen in small rooms. It is permissible to use such equipment only in places where there is effective natural or high-quality artificial ventilation.
Directly heated TPG
In addition to this disadvantage, there are positive qualities:
The indirectly heated gas gun has a ring heat exchanger. It is the basic heating product in the design. The operation of the installation is that everything happens according to the following algorithm:
This type of equipment is the most environmentally acceptable. In this regard, the use of indirect heating systems is more in demand. The downside, according to customer reviews, is the presence of a built-in chimney, which slightly complicates the movement of equipment and reduces mobility.
In order to achieve maximum results, it is worth knowing how to use a gas heat gun correctly. Manufacturers have taken care to simplify this process. The procedure is carried out according to the following scheme:
According to the output power parameters and the available area of the room, it is easy to calculate the desired value in Watts gun. To heat a 1 m2 apartment with an average ceiling of 2.5 m, 0.1 kW of power is sufficient. Accordingly, a 3 kW device can warm up a small room of 25-30 m2.
The most popular for domestic use are mobile type gas guns. They are equipped comfortable handles and wheels for transportation. Stationary heating equipment is equipped with a large gas cylinder, which is difficult to move quickly. Its dimensions affect the duration of uninterrupted operation. Such installations are considered obsolete.
Natural gas (methane) guns provide the desired indoor microclimate. They will be able to be used in garage conditions to create an optimal temperature balance. Often it is their builders who use them to work with suspended ceilings.
The built-in fan speeds up the air supply to consumers. The existing thermostat limits the heating.
A heat gun using liquefied gas (propane) is noisier in operation. Sometimes you can hear its second name: “thunder”. It is used as environmentally friendly equipment not only for heating, but also for scaring away wild animals or flocks of annoying birds.
For indirectly heated equipment permissible level noise is a value of 40 dB.
Modern heat guns are distinguished by maximum operating efficiency - the efficiency of the device is more than 90%, which no other similar equipment can boast of. It is also important that the burnt gas is not released into the surrounding area, that is, there is no risk of poisoning, and if the unit is used for greenhouses, winter gardens and other premises, the plants will not experience discomfort.
When choosing a model, you should consider whether it operates only from mains gas or whether it is possible to connect cylinders. In this case, the efficiency of the device is completely 100%.
In order for the TGP to cope with the assigned tasks, it is necessary to correctly determine its power in accordance with the area and purpose of the room. Next, the thermal insulation of the room is important - if there is heat loss, the power should be increased by 10-15% depending on the percentage of heat leakage.
The greater the power of the TPG, the faster it heats the room.
Be sure to find out the fuel consumption in order to calculate its amount in advance for uninterrupted operation. If there is a possibility of a power outage in the area, you should pay attention to models that do not require connection to the electrical network - here the piezoelements function in autonomous mode.
It is strictly forbidden to repair gas equipment yourself without special knowledge. For warranty and post-warranty service and repairs, you should contact specialized organizations.
VIDEO: Which is better - a gas or diesel gun?
Let's consider popular and time-tested samples from well-known brands.

Among the advantages:
VIDEO: The most economical way heat garage and warehouse
Promptly and efficiently - this is about heating with heat guns. There are situations when a residential or industrial premises needs to be warmed up very quickly, and then maintained at an optimal temperature with minimal maintenance costs.
A thermal gas gun successfully copes with these tasks - the unit is especially in demand when it is necessary to speed up the drying of construction and finishing materials V winter period, heating garages, greenhouses, retail outlets, etc. Still doubt the necessity and advisability of purchasing a heat gun?
We suggest you understand the features of the operation and use of gas heat generators, what parameters need to be taken into account when choosing a gun so that the purchase lives up to your expectations. In addition, we have prepared a review of the best manufacturers, whose products have earned a reputation for quality and reliability.
This is a portable or stationary device for heating air. Heat guns are used for heating spacious premises - houses, hangars, workshops and production halls.
The devices are easy to use and affordable. An additional plus: they are energy efficient.
The heating devices got their name due to their external resemblance to cannons. This design is due to the design features of heat guns and their functional purpose.
Heat guns are classified depending on the energy source on which they operate: gas, electricity, diesel fuel, waste oil. Since diesel fuel and waste have a specific odor, they are often installed in non-residential buildings.
Heat guns operating on different energy sources can be compared when we're talking about about premises for similar purposes. For all their advantages, heaters using diesel fuel or waste oil have significant limitations in use
A gas heat gun has several features that distinguish it from other types of heaters:
Gas heat guns have one more advantage, which practically does not depend on the power and other technical indicators of the models.
They effectively warm the air even in poorly insulated rooms. Under such conditions, the heat disappears quickly, but while the device is operating, a comfortable temperature is always maintained in the selected zone.
When selecting heating equipment, you need to clearly know in what conditions it will work. Depending on the characteristics of the room, the presence/absence of ventilation in it, you can choose a gas heat gun of direct or indirect heating.
Any equipment can break down, even the most expensive, high-quality and reliable one. Faulty gas equipment dangerous, therefore preventive maintenance should be carried out twice a year, and if necessary, minor repairs.
In case of complex breakdowns, you should not diagnose and repair the device yourself. This work should be carried out by service center specialists.
Let's consider the causes of equipment malfunctions:
When operating a heat gun, you must adhere to the manufacturer's recommendations. The equipment should be cleaned and washed on time, bearings should be lubricated and, if necessary, worn parts should be replaced.
An indirect heating gas gun can be a very good helper in home life and in some other areas. But for it to be useful, you need to familiarize yourself with general description, learn more about the types and models of such equipment. It is equally important to know, however, the basic criteria for choosing gas guns.
First you need to figure out what it is - an indirectly heated gas gun. This device uses the energy released by gas combustion to heat rooms. The power of gas guns is very high, because it is not limited by the power of electrical networks and is associated only with fuel consumption. In addition, the absence of the need for electricity increases the mobility of such equipment. Modern gas guns last a long time and are characterized by high thermal efficiency.
They are much more environmentally friendly than their diesel counterparts. In addition, natural gas (or rather, a propane-butane mixture) is significantly cheaper than diesel fuel. When it burns, almost no soot or soot appears. But we must remember that any gas equipment is source of increased danger.
The selection, connection and use of such equipment should be made as responsibly as possible.
Just burning gas is not the best The best decision . Then they will accumulate in the room harmful products combustion. Anyone who has ever seen what happens when a gas stove operates for 2-3 hours or more at closed windows. Indirect heating means that the firebox is completely isolated from the surrounding room. Admission fresh air and flue gases are removed through a special chimney.
A heat gun with exhaust of combustion products outside can operate on different types of fuel. Some models only run on propane or butane. Other modifications are more versatile and allow you to choose any type of gas. This is achieved using a special pressure stabilizer. The gas pressure in the main network is 0.015-0.02 MPa, and the gas cylinder reducer ensures equalization of this pressure to 0.036 MPa.
The difference in the energy value of liquefied and natural gas also forces the use of nozzles with different characteristics. Now it is useful to see which models modern manufacturers offered for garages and other similar premises. Has a very good reputation MASTER GREEN 310 SG. The weight of the device is 128 kg. Its dimensions are 1.5x0.628x1.085 m; thermal power reaches 75 kW.
There is another model from the same manufacturer - Green 470 SG. It already develops a power of 134 kW. The weight of the device is 219 kg. It will take 1.74x0.75x1.253 m. But this is not a record either.
The model can demonstrate the highest performance Ballu Biemmedue SP 150B Metano. It produces approximately 174 kW of heat. The air exchange level can reach 10,000 cubic meters. m in 60 minutes. To operate the system, you will need a current voltage of 380 or 400 V. Other parameters:
It’s worth taking into account from the very beginning that indirectly heated gas guns are not cheap. They cost several hundred thousand rubles. In addition, the total number of such models is small. Clear preference should be given to products from the well-known company Master. It is very reliable and lasts quite a long time. Optimal power is calculated by multiplying the volume of the room by the difference between the street temperature and the desired indicator, and then by the thermal insulation coefficient.
Thus, 125 kW of power allows you to heat at least 3200 sq. m and no more than 4100 sq. m of a new building with excellent thermal insulation. Therefore, it makes no sense to buy “the most powerful, so that you are guaranteed to have enough.” It is also worth considering that The more powerful the device, the louder it operates.
Connection to cylinders is justified only where it is impossible to use mains gas.
But wherever there are solid pipelines, it is still better to use them. Having a thermostat is very useful. When there is a thermostat, the gun will not heat the room after reaching the required parameters. Important: you should find out what specific type of fuel the gas gun is designed for. This will avoid many very unpleasant surprises.

Air heating is good because it does not require installation. One of the popular options for utility and industrial premises is a gas heat gun. This device quickly warms up the air, however, it cools down just as quickly when the gun is turned off.
This heating device is called a cannon for a reason: it is a cylinder on a support; more massive models have wheels for easier movement. Compact models are equipped with a special carrying handle. During operation, the case heats up to significant temperatures, so you shouldn’t touch it.
There is a fan in a cylindrical housing, followed by a burner behind it (closer to the “exit”). Air is sucked in from the back of the housing, passes through the fan, blowing the burner. Gas is supplied to the burner, which is ignited by ignition. The gas is mixed with the air flow, which promotes more complete combustion.
A good quality gas heat gun is designed in such a way that even at the highest power the flame does not extend beyond the body. There should be only a stream of hot air at the outlet. As you can see, the device is not too complicated and its operating principle is simple. The design is complemented by filters - air and fuel, various sensors and safety devices.
The main disadvantage of the above design is that combustion products remain in the room. It is clear that this has a negative impact on well-being and, as a result, on overall health. But this option has a very high efficiency - 95-98%. Therefore, these are the models that are chosen in production or for temporary use.
There are gas guns without exhaust. More precisely, the exhaust is removed from the room through a pipe. The design of such models is more complex. The combustion chamber is the same cylinder, only it is sealed in relation to the room. In the upper part it has an outlet pipe through which combustion products are removed. Heating occurs due to the fact that the air driven by the fan blows through the combustion chamber, taking away heat from the walls. That’s why these models are called indirect heating heat guns. First, the heat exchanger heats up, and the air from it heats up.
To ensure more complete heat extraction, gas from the combustion chamber moves through a labyrinth. This increases the efficiency, but this figure still does not rise above 80-85%. But such installations do not harm health, they can be used on a long-term basis.
At the moment, the range of indirectly heated gas guns is very scarce, and prices are high. First of all, these devices are aimed at large production and warehouse premises.

Let us remind you once again: a gas heat gun is not intended for use as permanent heating. It is great for quickly heating up a cold cottage, garage, etc. It performed well when heating buildings under construction. Can be used to speed up the drying of plaster and other mixtures (where technology allows it). But you should not use the unit for constant heating of a residential building.
Now the cons:
As you can see, this is far from an ideal option. But for quickly bringing rooms from sub-zero to positive temperatures - it’s very good. For example, when you arrive at a dacha that is heated by a stove, do not freeze until it warms up, but turn on the gas heat gun and after 15-20 minutes you can undress. An alternative might be . It is perhaps better for a dacha, but you need to think about the garage and other technical premises.
To roughly estimate the required power heating devices, counted by area. For a detached building in Middle Zone, requires 1 kW of heat per 10 square meters area. A gas heat gun is not intended for continuous heating. Usually it is taken to quickly warm up a technical room, cottage, garage, etc. Other devices are often used to maintain temperature. For this reason, traditional power calculations by area or volume are not suitable.
Calculation formula required power does not change:
It's easy to calculate. Let's give an example. A gas heat gun will heat a garage measuring 5 * 3.5 m, with a ceiling height of 3 m. The walls are one and a half bricks, only insulated metal gates. It is planned to increase the temperature from -10°C to +20°C. Substituting the initial data into the formula, we get:
In total, we found that this room could be heated by a 4.6 kW heat gun. But heating will last at least an hour - that’s how the formula is built. If you want to reduce the time, the power must be increased proportionally. If the time is halved (in 30 minutes), we multiply the power by two; to warm up in a quarter of an hour (15 minutes), the found power must be multiplied by 4:
The above calculation is approximate, but it allows you to estimate the required parameters. For those who don’t like to count, there are tables in which everything has already been calculated. But they are given “on average” without taking into account the characteristics of your buildings. You will have to take into account the necessary parameters yourself, choosing from the proposed “fork” of capacities.
Power is far from the only parameter that determines the choice. A gas heat gun still has a sufficient number of characteristics that are worth paying attention to.
Open fire and gas are a dangerous combination. In the case of a gas heat gun, there is also the possibility of carbon monoxide poisoning. So additional security measures are not superfluous. Here are the protective mechanisms this equipment may have:
The only thing that may raise doubts is air control. Since the sensor is built-in, the state directly near the device is analyzed, which can distort the real data. Therefore, it is better to have a separate detector. Detectors (sensors) are inexpensive and can be programmed.
Power is far from the only parameter that characterizes the operation of gas heat guns. There are a few more that are simply necessary to understand how efficiently the unit will work.
As you can see, there are quite a few options. Not all are obvious, some can be missed, but in general, pay attention to them.
Despite the fact that outwardly one heat gas gun is practically no different from another, some are convenient to use, others are not. This can be tracked using the following criteria.
Once again, we draw your attention to the fact that a gas heat gun is intended for rooms in which people are not constantly present. With sufficient power, it will very quickly heat the air even in a frozen room. But after turning it off, it cools down just as quickly: only the air heated up, and not the walls and other enclosing structures. However, as a means of rapid heating, it is very effective (although it consumes a lot of fuel).
The hardest part when buying is not choosing power or characteristics. This is, of course, important, but more important is the quality of the equipment. And it often depends on the manufacturer. Gas guns are no exception. Few people would agree to spend too much money on this equipment—the option is temporary. Usually they choose according to the price/quality criterion. “Half-Chinese” fit this category. These are those whose management is located in Europe-America, and production in China. Russian gas guns are in approximately the same category. Here is a list of popular brands:
It cannot be said that all models from the manufacturers listed above are successful. There are some that are very good, but there are some that are just so-so.
When choosing a gas gun both for heating rooms and for installing suspended ceilings, you should rely on reviews real owners. Let's look at the most popular models different power.

Despite the fact that when installing suspended ceilings it is safer to use electric heat guns, gas models of direct heating are more popular. This is due to the fact that gas guns have higher power and efficiency.
As a rule, professional “ceiling artists” have in their arsenal guns of different power - under different area ceilings. If we are talking about rooms up to 20 m², then a heat gun with a power of about 15 kW is sufficient. For example, Master BLP 17 M (16 kW) and Ballu BHG-20 (17 kW) are suitable. In small rooms it is more convenient to work with compact guns. As for safety, many experts recommend using composite cylinders.
If more is required universal option, then a direct heating gas gun with a power of 30-50 kW will be optimal. For example, RESANTA TGP-30000 (30 kW) or Master BLP 33 M (33 kW).
