Gas thermal. Gas heat guns. We collect all the pros and cons - how beneficial is a gas gun for heating rooms?

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:

• Liquid fuel devices,
• Gas units,

If the object is just being erected 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 natural gas will be quite suitable, just like .

Advantages of this heat gun

What should you consider if you decide to choose a gas heat gun? These are the capabilities of this equipment and its technical parameters. The advantages of such units include:

• High performance,
• Environmental friendliness,
• Waste-free combustion of the fuel used.

So a gas gun for heating rooms may be quite suitable as an environmentally friendly and efficient equipment. , which is used for such devices, is capable of burning without residue and providing an absolute coefficient useful action. Operation of this equipment is possible both from gas pipelines and from portable cylinders.

The principle of operation of gas guns

If you read reviews of gas guns for heating rooms, 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 what makes the equipment of this type independent from external energy sources.

Direct and indirect air heating

When choosing a gas gun direct heating, then all combustion products generated during operation will have to be forcibly removed outside, 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 cameras, in which the combustion process of natural gas takes place, and waste materials are discharged through a special pipe.

But there is one negative factor with these units - their 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 dangerous to use similar devices in residential areas. 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.

Which gas gun to choose?

If you have sufficient funds to purchase this device indirect action and the possibility of carrying out such procedures as modifying the gas gun to ensure constant removal of combustion products from the pipe and to the street, you can afford to purchase this particular unit.

Especially if it is intended to be used in residential premises where people will constantly be present. More suitable for direct heating construction projects where to create optimal temperature, but the presence of people is temporary.

The name “gun” was not given to these devices by chance. In terms of impact efficiency and heating speed, nothing else can compare with heat guns thermal equipment. The generated powerful flow of hot air can heat a room literally within a couple of minutes, and the scope of application of heat guns is not limited to heating. Heat guns are used to operate various types fuel or electricity. One of the most energy efficient among all types of this equipment are gas heat guns running on liquefied natural gas.

The main advantages of gas heat guns are:

• high power;
• environmental safety;
• efficiency - with high heating efficiency, the gas gun uses one of the cheapest types of fuel for its operation;
• mobility;
• durability;
• reliability.

Due to their technical and operational advantages, gas heat guns have a wide range of applications. Such heaters are used to service large industrial premises, hangars, workshops, garages, warehouse facilities, semi-enclosed parking areas, loading and unloading areas, etc. Gas guns are actively used to heat greenhouses, greenhouses, and agricultural farms. Such guns are indispensable construction sites, where they are used by builders to dry ceilings and walls.

One of the main advantages of a heat gun operating on liquefied gas is safety for environment and the absence of harmful combustion products, incl. unpleasant odors, smoke and soot. This is why she better side differs from models running on gasoline, fuel oil and other similar types of fuel. It is distinguished from electric guns by the lower cost of energy spent on heating, as evidenced by numerous user reviews.

Heat guns have a wide scope of application. They heat living quarters and are used for construction purposes. Operating on various energy sources, they are highly efficient heat sources. And within the framework of this review, we will consider such a device as a gas heat gun for residential premises and premises for other purposes. These units operate on gas fuel and are characterized by high efficiency.

We will cover the following topics:

• Design features of gas heat guns;
• Purpose of gas heat guns;
• Their varieties;
• The most popular models of heat guns.

After reading the material, you will receive maximum information about these units.

Design and principle of operation

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 unpleasant odor, 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 interior design a unit that uses gas for its power. By burning the incoming fuel, this unit produces large number 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 gas heat gun body is made of durable metal, since during operation its surface becomes very hot.

The device of a gas gun is as follows:

• Thermostat – provides temperature control;
• Fan - it provides the burner with oxygen and sends heat to the heated rooms;
• Control system - includes a thermostat and a start button;
• Burner is a module equipped with a nozzle and providing the creation of a flame torch.

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, find units that can operate in full offline mode, is almost impossible - 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 shoots 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.

On-board thermostats in gas heat guns monitor the temperature of the intake air - when a preset threshold is reached, the burner is temporarily turned off.

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. Gas cylinder for a heat gun - this 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.

Purpose of heat guns

Essentially, such a gun is a large gas burner. Only the fan located behind it makes it a heater.

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, for living rooms Less bulky and neater heating devices with low noise levels are more suitable.

In residential premises, thermal gas guns can be used during repairs and finishing works. With their help, the plaster is dried, the temperature is increased for more quick drying concrete screeds. They are also used during installation suspended ceilings– here you need a relatively high temperature necessary to stretch the fabric. And thanks to the directed heat flow, builders have the opportunity to carry out spot drying.

Another area of ​​application is ensuring air circulation in rooms. To do this, the heat gun is turned on in fan mode, without starting the gas burner.

Main varieties

All these units are divided into two large categories - with direct heating and with indirect heating. Heat guns with direct heating send combustion products into heated rooms along with hot air. They are not toxic, but this does not make breathing easier. But such units are characterized by high efficiency. For their work it is necessary good ventilation, operation in closed buildings and structures is prohibited.

Gas gun indirect heating- This is a more progressive, but more complex unit. Here, a closed combustion chamber is used with combustion products vented outside through a chimney. By blowing through the combustion chamber, the fan drives clean warm air into the room. True, such heat guns are very rarely found on sale, and their cost hits the buyer’s pocket hard.

Launching a heat gun

As we have already said, gas heat guns are powered by a gas cylinder (mostly). The startup process looks like this:

Due to the presence of a chimney, indirect heating heat guns are used as stationary heating systems, but they completely eliminate the possibility of combustion products entering the heated room.

• We screw the reducer with a hose to the gas cylinder;
• Connect the hose to the heat gun;
• We connect the unit to the electrical network;
• Press the start button and set the desired temperature.

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.

In indirect heating models, it is necessary to bring the chimney outside - flexible corrugated pipes are used for this.

Advantages and disadvantages

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:

• Economical - for example, for a 30 kW heater, gas consumption per hour will be just over 2 kg;
• No strong odor combustion products - fuel burns almost completely;
• Comparative miniature - in contrast to diesel units, there is no tank here.

Negative features:

Some craftsmen who want to save money make heat guns themselves. The safety of such crafts leaves much to be desired. We advise you not to resort to using such units.

• Unsafety - this feature is inherent in all gas appliances, including kitchen stoves;
• The need to use electricity – at sites without electrification you will have to use a generator;
• Difficulty connecting to the highway - this requires a special permit.

Nevertheless, gas heat guns continue to be in demand equipment, especially in the construction industry.

How to choose a suitable heat gun

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 installation 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.

When choosing a heat gun in the catalog of a particular store, carefully read the descriptions - all the characteristics and features are indicated there. And by looking at the Yandex.Market catalog, you can read the reviews. By the way, they all point to high efficiency and unpretentiousness of these devices.

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 trademark Master.

Popular models

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.

Master BLP 33 M

Before us is one of the simplest gas heat guns, the price of which varies between 11-12 thousand rubles. The unit is devoid of thermoregulation, its productivity is 1000 cubic meters. m/hour is a good indicator. The heat gun turned out to be compact, light and powerful. Its weight is only 9 kg and its power is 15 kW. The model is aimed at use for construction purposes. And in order to ensure long-term and continuous work, you can connect several gas cylinders to it at once.

This is a gas heat gun with a thermostat and temperature control, which will literally cost you 9-10 thousand rubles. The device is equipped with a tilt angle adjustment system, and it is also extremely easy to operate - the thermostat and switch are combined into one single handle. Its thermal power is 50 kW, but the heated area is only 300 sq. m. m. Fuel consumption varies from 2.2 to 3.2 kg/h. Despite the low price, this heat gun cannot compete with the model described above.

The presented model is distinguished by its compactness, which makes it easy to transport. It is designed to run on liquefied gas, maximum flow is 0.8 kg/hour. The weight of the device is a little more than 5 kg. The kit already includes a hose and a reducer - you do not have to purchase them separately. As in the previous unit, the angle of inclination can be adjusted here, and the stable stand prevents accidental tipping. This is an excellent heat gun for a mobile construction crew.

Before us is a fairly powerful gun with an advanced ignition system. Its power is 31 kW, maximum performance is 1000 cubic meters. m/hour. This is quite enough for construction needs and heating of large premises. The heat gun is equipped with a system temperature control. As for ignition, the burner contains three electrodes at once - this ensures instant ignition of the incoming gas.

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.

The cost of this unit is about 10 thousand rubles - great choice for heating premises for various purposes.

It would be strange not to mention the name of this famous brand in our review. The presented heat gun is characterized by compactness and high power– 17 kW. Its capacity is 270 cubic meters. m/hour. Let's consider the main advantages of this unit:

• Low cost - it is about 5,000 rubles;
• Reducer and durable hose included as standard;
• Reliable and durable burner with protection against ignition at low gas pressure;
• Complete shutdown in case of power failure;
• Practically complete combustion fuel.

There is no electric ignition here; a simple piezoelectric element is responsible for this. The heat gun is also equipped with overheating protection.

Why the manufacturer did not give this gas heat gun a normal model designation is not entirely clear. In general, the unit is not bad, its thermal power is 10 kW, and its maximum productivity is 300 cubic meters. m/hour. Moreover, during this hour it consumes only 727 grams of fuel (propane or butane). The gas burns completely, without producing a characteristic odor.

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.

Together with this model, heat guns with increased power are produced - up to 85 kW. They differ in increased dimensions, but this does not change the functionality.

In buildings that are not equipped or connected to the system central heating, a gas gun is often used to heat rooms. This mobile and easy-to-use device with a thermostat is able to quickly heat the air in the room and maintain a comfortable microclimate at a given level. Therefore, many owners of country and private houses, as well as production premises prefer gas guns to their diesel counterparts.

Heating equipment This class is used as a permanent or temporary heat source. In fact, a gas gun is an ordinary fan heater, but on gas, which, due to its design features, has high level efficiency and expanded functionality. The device releases warm air into the room, which is formed during the combustion of fuel.

The device is placed in a metal case, which has outlet openings designed to allow hot air to escape. Inside the body the heat gun contains:

• fan;
• burner;
• control device;
• heat exchanger;
• ignition device;
• thermostat.

In addition, inside the case can be placed additional elements, depending on the type of model and design features.

How does a gas gun work:

1. A burner is placed in the combustion chamber, where gas is supplied.
2. The device that provides ignition ignites the fuel, due to which the heat exchanger heats up.
3. The fan draws in cold air and directs it back through the heat exchanger structure.
4. Equipment protection from overheating and malfunctions is provided using a thermostat.
5. When the air in the room warms up to the set point, the thermostat is activated and the switch opens electrical circuit, due to which the gun stops working. When the temperature drops a few degrees, the device turns on again.

This operating principle gas appliance heating allows you to maintain an optimal microclimate in the room.

Gas-powered heat guns have a number of advantages. Among the most significant advantages it is worth noting the mobility of installations, easy operation, as well as the affordable cost of units that operate with bottled gas. Besides, this type heating devices has high rate Efficiency, at minimum consumption electrical energy.

Types of gas heat guns

Gas guns There are two types for heating, depending on the fuel consumed. Some operate only on liquefied gas, which is in a cylinder - propane or butane. The second type of device is universal and can operate on any type of gas, because their body contains an element that ensures pressure stabilization. The presence of this component allows you to connect the device directly to the gas main.

Depending on the type of fuel consumed by the device, it may have certain characteristics. The gas pressure in the general network varies between 0.015-0.02 MPa, so the devices are designed for different inlet pressures. But at the output, the reducer installed on the gas cylinder has an indicator of 0.036 MPa.

The differences between these types of units also affect the nozzles, which may have different diameter nozzles, because the calorie content of natural and liquefied gas differ significantly. Bottled gas is three times more calorific than main gas, so if the functions of the gun do not include the use of main fuel, then you should not connect to it a heater designed only for bottled liquefied fuel.

Attention! During the operation of a heat gun, oxygen is necessarily burned out. Therefore, these devices are not recommended for use in rooms without ventilation system. This is life-threatening!

Based on the type of construction, there are only two types of these devices: gas gun of indirect heating and direct. Let's look at the features of each variety.

Direct heating device

The design of a direct-heating gas gun is not equipped with the function of purifying air flows from burning, so in residential areas they can poison oxygen. This is the only but very significant drawback of these devices, which forces consumers to make a choice that is not in their favor.

At the same time, direct heating units have an efficiency of 100% and during their operation consume a minimum amount of fuel and electricity.

The design of direct heating equipment is quite simple: a fan and a burner are placed inside the housing, heating cold air currents, and the fan blows them into the space, creating a powerful stream of air.

Indirect heating device

Gas heat gun with indirect heating as heating element uses a ring type heat exchanger. The working process of these devices differs from direct models in that fuel is first burned inside the housing, and then toxic products that are released as a result of the combustion process. Therefore, this type of guns is considered environmentally friendly and absolutely harmless to human health.

For obvious reasons, devices with indirect heating are popular among consumers for heating homes. Installation of such guns is allowed even in rooms with poor ventilation systems.

However, this design also has one, but very significant drawback - the presence of a chimney pipe in the body, which reduces the mobility of the device and creates difficulties in its transportation.

Pay attention! Compact models guns powered by natural gas are very economical. The unit consumption is only 1 l/h.

Areas of application of gas guns

The popularity of gas heat guns is determined by their safety, practicality and wide area applications. These devices are used not only for heating living rooms, but also for domestic needs: drying objects with large dimensions, as well as for ventilation of rooms.

Operating a gas gun in a garage will create conditions for normal starting of the car, as well as performing repair work. In addition, the gas gun is in demand not only in living conditions, but also in production. This equipment is used for quality and economical heating greenhouses, greenhouses where vegetables, seedlings and flowers are grown.

A gas gun is a self-contained heating device, but it can also become structural element the whole installation, which is designed to maintain the necessary indoor microclimate. Structures that run on natural gas can be used to heat automotive, agricultural and specialized equipment.

The capabilities of this device are often used during repairs, when it is necessary to quickly dry walls after puttying. In addition, this type of equipment is used when installing suspended ceilings, since the fan built into the structure speeds up these processes.

Besides, functionality gas heat guns will be useful for large areas, the size of which exceeds 25 m².

How to choose a gas heater?

To select a device with suitable parameters, the following characteristics must be taken into account:

• the material from which the building is constructed (brick, stone or metal);
• quality of thermal insulation (types and features of internal and external insulation);
• absence or presence in the room electrical wiring(without electricity the gun will not be able to work);
• features of the ventilation system;
• total area of ​​the room;
• operations that take place indoors.
• manufacturer and level of product quality;
• gas gun body shape;
• heating method (direct or indirect);
• unit power level;
• dimensions of the device.

In addition, it would be a good idea to read reviews from other consumers who have already purchased and used the device.

Frequent breakdowns and their elimination

Common problems with gas guns and possible causes:

1. The flame goes out when the forced fuel supply button is released - this may indicate a breakdown of the safety sensor.
2. There is no ignition when gas is supplied - there may be no spark in the design, so adjustment of the piezoelectric element may be required.
3. The fan operates without fuel supply - this sign indicates a malfunction of the solenoid valve.
4. It is not possible to adjust the fuel supply while the device is operating - most likely, the gas line is clogged.
5. During operation, a strong smell of carbon monoxide appears - the device needs to be cleaned and adjusted to the gas pipeline on the heat generator. You must immediately turn off the equipment and under no circumstances continue to use it.

Important! It is better not to risk trying to repair the device yourself. All repair work should be performed by a professional.

How to make a gas gun with your own hands?

If your knowledge and experience allow you to make such a complex heating device yourself, then you can make an indirect heating gas gun with your own hands.

To make the device you will need:

• two pipes 1 m long and with a diameter of 18 cm (body) 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;
• gas burner equipped with a piezoelectric element.

Before you start creating a device, you should carefully study the diagram, which will become a guide during the work process.

Do-it-yourself gas heat gun manufacturing technology:

1. First you need to take the pipe from large size 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 is 1 cm. This hole will be used to fix the gas hose. You need to make a combustion chamber from a pipe with a diameter of 8 cm.
2. Then you need to assemble the plug. It can be cut from a sheet of metal. This part must cover the gap between the housing part and the combustion chamber. In this case, it is very important not to block access so that it is possible to connect the structure to the chimney.
3. After this, all the elements come together. For this you will need welding machine and skills to handle it. The combustion chamber along with stiffeners is welded inside a large pipe. A pipe and a plug are fixed from the outside. Through this element, heated air will enter the room. All that remains is to install the gas burner and fan. All elements must be firmly fixed.

Useful advice! To keep the combustion chamber firmly in the central part of the housing, it is better to use plates that are welded to the pipe.

The process of assembling a direct fired gun is much simpler. Such a device consists of a pipe, at one end of which a fan and burner are attached. Combustion products and hot air flows will come out from the opposite side.

Safety precautions when operating a gas gun

A gas heat gun is very simple to use. If you follow the rules of its operation, the equipment will not pose any danger to human life or health.

Basic safety rules when operating a gas heat gun:

1. Do not dry shoes, clothes and other items on the device body, as well as any actions during which the air duct or air collector may be blocked.
2. The device housing and fan must be protected from moisture.
3. It is imperative to use wiring with a power corresponding to technical parameters apparatus.
4. Do not operate the unit in a dirty room with a high concentration of dust.
5. In a building where a direct heating gun is used, it is necessary to organize good ventilation.
6. You can't bet on close range dangerous and flammable substances from the device.
7. The area where the gas hose is attached to the fuel cylinder must be checked for complete leaks. Leaks are not allowed.
8. The gas is much heavier than air, so it can accumulate at the bottom of the room, creating an explosive situation. Therefore, it is prohibited to operate gas guns in rooms that are below ground level.

Before turning on the device, you need to read the operating instructions, which describe all the nuances of connecting and using the device.

Thus, a gas gun for heating rooms is an economical, safe and compact device with high efficiency, therefore these devices are considered the best way heating air in buildings with different areas and large volume. Such units can become an alternative standard way heating.

Heat guns are one of the most powerful tools for heating a room. Are analogue traditional heaters, but with significantly greater power and a convection system that blows out a powerful heat flow. On average, a gas heating gun with a capacity of 10 – 15 kW capable of 20 minutes in a room with an area of 150 m2 raise the temperature by 5 – 10 ℃ . Traditional electric heaters simply do not have such power, since only industrial electrical networks can withstand such a load.

“Gas guns” are based on the most common burner (burner), which heats the air by burning oxygen to form carbon dioxide and fumes. This entire mixture is blown out of the combustion chamber using a powerful fan driven from the electrical network.

Unlike diesel guns, in gas engines, during combustion of fuel, a minimal amount is formed harmful substances and carbon monoxide, so they require less performance forced ventilation. But at the same time, their heating speed and power are identical. And, by the way, the design of gas guns is simpler than that of diesel ones, so they break extremely rarely (only if operating rules are violated), and manufacturers give a guarantee, on average, for 3 – 6 years for such devices.

Closed and open guns

Conventionally, all gas guns are classified into open and closed:

• Open(direct heating). Have more simple design, the burner is open, all combusted gases enter the room. Required for normal operation require high-quality ventilation heated room.

Open burner gun. A more common option, but it can only be used in those rooms where there is normal supply ventilation. Otherwise, carbon dioxide accumulates and carbon monoxide, and it is extremely dangerous for a person to be in such a room

• Closed(indirect heating). The burner is closed, and there is also an outlet for removing waste gas. Such guns are less powerful and efficient and require a mandatory connection to the chimney, but are absolutely safe (and can be used powerfully even in small living spaces). Either air heating elements or radiators (ring heaters) are used as a heating element.

Heat gun closed type. IN in this case— installed outdoors, and warm air is supplied through a special air duct

As a rule, open ones are used in non-residential premises ( garage, shed, warehouse), closed - in residential areas or in those where there are problems with ventilation.

Classification by connection type

Gas guns according to the type of connection and the fuel used are divided into:

1. Methane. These are connected directly to the household gas distribution network. It is also possible to supply methane from cylinders, but these are not refilled at all gas stations (the process itself is long and requires the use of special equipment).
2. Propane. They operate on a propane-butane mixture and are connected to cylinders. These are more common, since propane is quite cheap, filling it into a cylinder takes a minimum of time.

Pros and cons of heat guns

The obvious advantages of gas heat guns include:

• low cost;
• simplicity of design(most of the breakdowns can be quickly fixed on your own);
• saving(heating is much cheaper than with guns on diesel fuel, “working out” or electricity, some models are even connected to the household gas distribution network);
• high power with small dimensions and weight (the average weight of a gun with all the body kit is from 5 to 15 kilograms, depending on power);
• There are models with support for connecting electricity via batteries (operability does not depend on the availability of an electrical network);
• much safer than diesel ones.

Such a gun in 1 hour active work burns about 1.5 - 2 liters of gas (at maximum power). And this is enough to heat a room over 200 square meters. Electric heater for this it will spend at least 40 kWh of energy, which will cost several times more (and it will take much more time)

But they also have disadvantages. The significant ones include:

• gas is used as fuel; if the operating rules of the device are violated, this will lead to fire;
• necessary high-quality heated room (otherwise you can get carbon monoxide poisoning);
• require regular maintenance(in particular, cleaning the gas supply system, changing filters, and so on);
• uneven heating room (warm air accumulates at the top, cold air sinks to the floor, the temperature difference can reach 20 degrees).

Additional features

Additional functions in gas heat guns include:

1. System automatic arson. It works either from the mains or as a mechanical piezo element. If they are absent, the device is started manually (by bringing a match or any other burning element to the burner nozzle).
2. Rotation speed adjustment fan This functionality allows you to adjust the power of the air flow. For small rooms – less, for large ones – more.
3. Gas supply adjustment. Used to turn on “turbo mode”, when the heating element heats up in literally 10 - 20 seconds. Allows you to start heating the room instantly.
4. Availability additional sensors. These include a gas leak sensor, a gas pressure reduction sensor, a thermostat (responsive to ambient temperature), a position indicator (if the gun accidentally tips over, it blocks the gas supply and the device turns off).
5. Thermocouple. Allows the fan to automatically adjust the rotation speed depending on the temperature in the combustion chamber or heating element.

Manufacturers also began to produce automatic gas guns that operate on the principle of conventional electric heaters with a thermostat. That is, they turn on and off automatically, maintaining the room temperature at a given level. However, the response threshold of such devices is high, so you should not count on carefully observing the temperature down to 0.5 degrees.

How to make a gas gun with your own hands - step-by-step instructions

Knowing the operating principle of the simplest gas gun, you can understand that making the same design at home yourself will not be a problem. The main thing is to select components. As a body, you can use either a piece of galvanized pipe on the outside, with a diameter of 100 mm(recommended - 200 mm), and any primus stove is suitable as a burner (preferably with adjustable fuel supply intensity to the burner). All this can be purchased at a construction or household goods store.

Another nuance is forced convection. With a powerful gas flow, it is not necessary to install a system that will independently blow out heated air. The main thing is to use a pipe that does not have sealed ends, because in this case the air flow is created automatically (due to the difference in air temperatures at the ends of the cylinder).

If convection is still necessary, then a regular one is simply installed from the back of the pipe. household fan. The main thing is to adjust the rotation speed of the blades so that the air flow created does not lead to extinguishing the burner. As a rule, 200 – 300 rpm enough.

Aluminum container as a gas gun. The advantage of this design is the high heat transfer coefficient. But the durability of this option is debatable.

In total, to create a gas gun with your own hands you need:

Step 1. Select a suitable housing. Ideally, a steel pipe with a diameter of 200 mm and no less long 80 centimeters.

Step 2. Prepare a hole in the upper part of the pipe for installing a nozzle with a burner. This can be done using a step drill. Standard nozzle inlet - approx. 25 mm(then you can water tap install, but it is recommended to install a gas one - they are structurally different).

Step 3. Install the burner. All this is secured to a washer or coupling that is tightened on the outside of the pipe. A fire-resistant sealant (automotive sealant, the one used when installing gaskets in the cylinder block) must be added under all fasteners to avoid gas leakage and reverse thrust in the combustion chamber.

Step 4. If necessary, install a fan behind the pipe. It is not necessary to make everything airtight, the main thing is to create a directed air flow.

Step 5. Connect the resulting gun to a gas source (propane or methane - depending on the type of burner installed) and conduct a test run. Of course, there is no provision for automatic ignition in such a system, so the burner will need to be started manually.

During a test run, the most important thing is to make sure no gas leakage(check all connections), as well as the normal heating of the burner (it should not overheat, become covered with soot or turn red).

The test run and performance check are carried out outdoors and not indoors. But it should be remembered that such devices are very dangerous, therefore, without proper experience, trying to make them yourself is not a good idea. best solution. And when working with them, there must be someone nearby so that if any breakdown occurs, they can immediately turn off the device.

You should not use self-made heat guns specifically for heating. They are better suited for quickly drying a room or for heat treatment of surfaces (for example, to combat mold and mildew).

How to choose a gas gun in a store and what to look for

When choosing a gas gun for household use You should first pay attention to the following parameters:

1. Power. It is measured in kW; sometimes manufacturers additionally indicate the volume of heated air per 1 hour of operation. In the first case, the formula is followed: 1 kW on 10 m2– minimum. Secondly, it is necessary to calculate the total volume of the room planned for heating with a gun and divide the resulting figure by 2. This will give the minimum power of the gun, with which the room can be heated within just 30 minutes continuous operation of the heater. For example, the volume of air heated by a gun is 300 m 3. Accordingly, it is optimally suited for a room with a volume of 150 m 3(volume and area should not be confused - these are completely different indicators).
2. Connection type. This means with a closed or open burner. The first ones are more expensive and they are used for “emergency” heating of residential premises. It is not worth buying them for other purposes. Open – best option for garages, sheds, warehouses and other non-residential premises.
3. Presence of automatic arson. In principle, the function is not required. Moreover, piezoelectric elements fail quite quickly, but at the same time their presence is almost limited 10 – 20% increases the cost of the gun.
4. Availability of additional functions. This means adjusting the fan speed, sensor system, thermostats, and so on. All of them help automate the operation of the gun, but manufacturers do not recommend heaters similar type leave them working without supervision. And the presence of those same sensors also increases the final cost of the device. If you need to save money, you can buy a gun without all these sensors.
5. Nutrition for a fan. Occurs either from 220V, or from 12V DC. The last option is convenient because the gun can be used as a mobile gun, launching it even in the absence of a household electrical outlet. If such functionality is not needed, then it is better to take it with the simplest 220V motor. Even better - without brushes (such motors are very reliable and durable, but are quite expensive).

An option for using gas guns is for installing suspended ceilings. Under the influence high temperature PVC fabric stretches easily, there are no folds or dents left on it

Review of popular models

Analyzing information on thematic forums, the following popular ones can be identified: gas burners among Russian consumers:

1. MASTER BLP 17M. Ideal option for heating a garage. Reliable and durable equipment, the reducer is “unpretentious” to the quality of the supplied gas. There is a power regulator from 10 to 16 kW, so it is suitable for garages up to 150 m 2. The only negative is manual ignition, although because of this the device almost never breaks down; the manufacturer generally gives a 3-year warranty. The average cost is 9 thousand rubles.
2. SPECIAL IGE-15. Gun Russian production. Has small sizes, suitable for use when installing suspended ceilings or for drying walls after painting. Power is 15 kW, but the flow is narrowly targeted. It has 2 heating stages, the kit includes a hose for connecting to the cylinder (with adapters). Average price– 5.2 thousand rubles.
3. Caliber TPG-10. Also made in Russia, power up to 10 kW, suitable for small rooms. The gearbox is collapsible, the manufacturer has provided for its complete replacement with an analogue one. The fan is also serviceable and not pressed into a bearing. But the functionality is minimal. But the cost is only 4 thousand rubles.
4. Kroll P 10. Popular model foreign production. It works when connected to cylinders, there is a piezo ignition, a safety thermostat and a pressure sensor. The productivity is small - up to 300 m 3 per hour, but the flow of heated air is not narrowly targeted, as in other models. The average price is 9.5 thousand rubles.
5. Profteplo KG-57. Industrial type heat gun with a capacity of up to 1400 m 3 per hour. Available in two versions - with connection to 220V and 380V. The latter is noisy in operation, but it is not suitable for small spaces. There is flame control, as well as a sensor that turns off the gun when it detects movement in front of it (it can be forcibly turned off). The average price is 11 thousand rubles.

Total, gas gun - great option for quick heating of non-residential premises. For residential - not best option, as it requires connection to the chimney. But you can make a cannon yourself; all this will require only 2–3 thousand rubles (for all materials).
