Gas gun for heating. Gas guns of indirect heating. How to correctly calculate the power of a heat gun before buying

Heat guns have a wide range of applications. They heat living quarters and are used for construction purposes. Operating on various energy carriers, they are highly efficient sources of heat. And as part 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;
• Appointment 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 considered performance heat guns operating on liquid fuel. They have a high efficiency, but are sources bad smell, since the fuel in them does not burn 100%. An alternative to them is gas units operating on natural or liquefied gas (liquefied gas is most often used - a little later we will explain what this is connected with).

A gas gun for space heating is a relatively simple unit in terms of internal arrangement that uses gas for its power supply. By burning the incoming fuel, this unit produces a large number of heat that is sent into the room with the help of powerful fan. The heart of the device is a burner with an ignition system - simple piezoelectric elements and electrical ignition systems with electrodes are used here.

The body of the gas heat gun is made of durable metal because the surface becomes very hot during operation.

The device of the gas gun is as follows:

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

In some models of gas heat guns, there are also heat exchangers - they serve to safely transfer heat to heated buildings and premises.

A gas gun cannot work without electricity, since its essence is to “shoot” heat under high pressure, characterized by high performance. Without a fan, it would turn into the simplest burner that cannot boast of high efficiency. Therefore, it is almost impossible to find units that can work in a completely autonomous mode - a power source is required here.

The gas heat gun is enclosed in a durable metal case and with all its appearance really resembles some kind of cannon that shoots cannonballs. Only instead of nuclei, hot air flies out of its mouth. Due to the built-in fan, the heated air masses are evenly distributed over the heated volume. Thermostat models monitor the temperature generated, providing precise temperature control.

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

Two types of fuel are used to power gas heat guns for residential premises - it is main gas or liquefied gas from a cylinder. In the first case, everything is not so simple, because you need permission to connect to the highway. Therefore, most often, liquefied fuel is used to power the units. The gas bottle for a heat gun is the same bottle that is used in conjunction with conventional kitchen stoves. Its volume is not limited in any way, connection to heat guns is carried out through a pressure reducer.

Purpose of heat guns

In essence, 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- it can be different hangars, production shops, renovated buildings and warehouses. At the same time, people can be there at the time of work if decent 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 works. With their help, dry the plaster, increase the temperature for faster drying concrete screeds. They are also used for installation. stretch ceilings- a relatively high temperature is needed here, which is necessary for stretching the web. And thanks to the directed heat flow, builders have the opportunity to carry out spot drying.

Another area of ​​application is the provision of air circulation in rooms. To do this, the heat gun is switched 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 to heated rooms together with hot air. They are not toxic, but it does not make breathing easier. But such units are characterized by high efficiency. Good ventilation is required for their operation; operation in closed buildings and structures is prohibited.

An indirectly heated gas gun is a more advanced, but more complex unit. Here, a closed combustion chamber is used with the removal of combustion products to the outside, through the chimney. By blowing the combustion chamber, the fan drives clean warm air into the room. True, such heat guns are very rare 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, heat guns of indirect heating are used as stationary heating systems, but they completely exclude the possibility of combustion products entering the heated room.

• We fasten a reducer with a hose to the gas cylinder;
• We 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 - for this, flexible corrugated pipes are used.

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 positives:

• Profitability - for example, for a heater with a power of 30 kW, the gas consumption per hour will be just over 2 kg;
• There is no strong smell of combustion products - the fuel burns out almost completely;
• Comparative miniaturization - unlike diesel units, there is no tank here.

Negative Traits:

Individual craftsmen who want to save money make heat guns on their own. The safety of such crafts leaves much to be desired. We advise you not to resort to the use of such units.

• Insecurity - this feature is inherent in all gas appliances, including kitchen stoves;
• The need to use electricity - at facilities without electrification, you will have to use a generator;
• The difficulty of 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 the right heat gun

If you are going to buy a gas heat gun, be guided by 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 model more powerful.

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. For heating 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 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 into 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 and foreign devices, then you will not be able to give someone special preference. Russian and foreign brands make good gas heat guns, characterized by endurance and good technical specifications. But if we turn to the ratings, they are headed by the Master trademark.

Popular Models

Enough theory - let's move on to practice. Now we will consider the most popular models of gas heat guns. All of them are direct heating models.

Master BLP 33M

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 capacity is 1000 cubic meters. m / h 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 intended for use in construction purposes. And in order to ensure long-term and continuous operation, several gas cylinders can be connected to it at once.

This is a gas heat gun with a thermostat and temperature control, which will cost you literally 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 a single handle. Its thermal power is 50 kW, but the heated area is only 300 square meters. 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 differs in the compactness that facilitates its transportation. It is designed to work on liquefied gas, the maximum flow rate is 0.8 kg / h. The weight of the device is a little more than 5 kg. The kit already comes with a hose and reducer - they do not have to be purchased separately. As with the previous unit, here you can adjust the angle of inclination, and a stable stand prevents accidental tipping. This is an excellent heat gun for a mobile construction team.

We have enough powerful cannon with an advanced ignition system. Its power is 31 kW, the maximum performance indicator 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 temperature control system. As for ignition, there are three electrodes in the burner at once - this ensures instant ignition of the incoming gas.

In order to extend the life of the unit, the manufacturer endowed it with protection against overheating. As soon as the excess of certain indicators is recorded, the equipment will turn off the gas supply and resume it after cooling. Also, the heat gun provides protection of the body from corrosion - for this, the body is covered with a special coating. The heat gun is notable for its unpretentiousness in operation and efficiency - it burns only 2.27 kg of gas fuel per hour.

The cost of this unit is about 10 thousand rubles - an excellent choice for heating rooms for various purposes.

It would be strange not to mention the name of this well-known 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. Consider the main advantages of this unit:

• Low cost - it is about 5000 rubles;
• Reducer and durable hose 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. Also the heat gun is equipped with protection against an overheat.

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 the maximum performance 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 the formation of a characteristic odor.

The heat gun turned out to be compact - its dimensions are 435x230x305 mm. It's a great choice for construction crews and anyone who needs a portable gas heater with decent performance. The official cost from the manufacturer is 4499 rubles, which makes this heat gun one of the most affordable devices.

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

To maintain the room temperature in winter period with absence central heating, you can use a gas gun, which has a high rate of efficiency and economically consumes electricity. In fact, this is a gas fan heater, among the advantages of which one can single out mobility, ease of use, low price.

What is a heat gun

Demand for such modern unit increases several times during the heating season in the absence of central heating or its poor quality supply. Gas heaters for heating emit warm air, which is formed by burning gas. Outwardly, this is a streamlined metal case with a hole for the exit of a hot stream, and inside the design is somewhat complicated and is represented by the following elements:

• burner;
• fan;
• heat exchanger;
• ignition device;
• control device;
• thermostat;
• additional devices depending on the design features.

Types of gas guns

Before making the final choice, it is important to find out what types of structures exist, which option in a particular case is optimal. The gas heat gun enjoys considerable popularity, it is necessary for heating and ventilation of residential premises, drying of overall objects. The range is wide, but the classification provides for only two design features - direct and indirect heating. Both options are suitable for domestic needs, but have different appearance, operating principle.

direct heating

In this design, air flows are not cleaned from burning, so they all gather in a living room, poison oxygen. Directly heated gas guns are needed where there is sufficient natural or artificial ventilation. This is the main drawback of the gun, but 100% efficiency, minimal energy and fuel consumption remain significant advantages.

indirect heating

The ring heat exchanger acts as the main heating element, which operates according to the following principle: gas is burned first, then toxic products that are released during the formation of fuel. The gas heat gun of indirect heating is an environmentally friendly device, so its installation in the room is possible even with limited ventilation. The disadvantage of this mechanism is the presence chimney, which complicates the mobility and transportation of a gas-type gun.

How does it work

Before using the gun home environment, it is necessary to understand in detail how it works, how it functions correctly, which manufacturer is the best in a given direction. This greatly facilitates the final choice of a suitable design, simplifies the operation process. The principle of operation of a gas gun is as follows:

1. In the combustion chamber there is a special burner, where the gas flow is supplied.
2. With the help of an ignition device, the gas burns, the heat exchanger heats up.
3. The fan blows cold air from environment, directs through the heat exchanger.
4. A thermostat specially inserted into the circuit protects the unit from overheating and breakdown.
5. The presence of a switch breaks the electrical circuit when the room is heated to the desired value on the thermometer.

Gas gun device

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 gas bottle which is difficult to transport. The duration of operation of the unit itself, its technical characteristics depend on its volume. Such a stationary design of an indirect blown gas gun is considered obsolete, impractical to use, mobile models are more in demand in the range.

Heat gun on gas

This is an independent heating device and a structural component of the heating installation, necessary to maintain the desired climatic conditions in a residential area and not only. A natural gas heat gun can be used to heat automotive and special equipment, it is useful in the repair process and for the installation of stretch ceilings. The presence of a fan allows you to speed up the process, and a built-in thermostat controls the heating of the air flow. The gas gun works suitable model can be ordered from the online store.

propane gun

It is also called a thunder gun, because you can hear a loud bang in the process. If the previous model operates on gas, then the specified unit has its own design features. A propane heat gun is an environmentally friendly device often used to scare away birds and wildlife. Among the advantages, connoisseurs highlight the simplicity of design, lightness and economy.

Application

Such gas-powered equipment is in demand in everyday life and in production, and has found wide application among the masses. This is not only the rapid heating of residential and non-residential premises, but also the drying of individual items for automotive and industrial purposes. In addition, the use of a gas gun is appropriate for large areas - from 25 sq. meters, in the process of repair work, for example, when installing stretch ceilings.

for garage

These non-residential premises are characterized by dampness, which only prevents the storage and safety of personal vehicle. To dry the walls and remove the 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 garage footage, the quality of thermal insulation, the mode of presence of people in such non-residential premises. There are two options for choosing guns:

1. The gas gun can be used when there are no people in the room. The unit provides high power, fast heating of the garage, minimal energy costs.
2. A diesel gun is appropriate if people are or live in the garage. Due to the presence of an exhaust pipe, combustion products are efficiently removed and do not settle on the walls.

For residential heating

Considering the comparative characteristic described above, it becomes obvious that stationary direct blowing structures are not suitable for heating this 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.

For stretch ceilings

When carrying out repair work, this unit is also needed. A gas heat gun for the installation of stretch ceilings is an indispensable "tool", since when the PVC film is heated to 65 degrees over the entire surface, it makes it elastic and pliable. The material easily lays on the ceiling, firmly attached to pre-prepared gaps. If the gas gun is turned on when performing this type of work, condensate does not accumulate on the carrier plate during the fixing of the PVC film. This is one of the important advantages of the participation of the mechanism in the course of repair work.

How to use a gas gun

If a person is superficially aware of how to turn on and off the indicated mechanism, this does not mean at all that he is perfectly aware of 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 wizard. When using a stationary gun, the following rules must be observed:

1. Exclude the presence of flammable substances in the room to prevent their ignition.
2. Ensure unhindered access of oxygen, due to which the gas gun actively supports the combustion process.
3. It is forbidden to block the outlet and turn on the fan.
4. Since the air must circulate and not accumulate in the heat gun, it is necessary to install the unit in an open area, to exclude clogging of the outlets.
5. The gas supply should be carried out if the gas gun is not broken, it works properly.
6. Turn on the ignition button until the piezo element or piezo ignition is activated.
7. To prevent fuel leakage, it will prevent an additional fuse from being introduced into the circuit.
8. You should not save on fuel, otherwise the gas heat gun may fail very soon.

How to choose a gas heat gun

The most difficult thing is to make a choice, since a huge number of positions are declared in the catalogs. interesting design with unique specifications. To buy a gas gun and not miscalculate, it is important to compare with electric and diesel designs. Someone prefers 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 the rating guns on gas, which have confirmed their effectiveness and cost-effectiveness of use.

• pluses - low price, minimal fuel consumption, convenient home use;
• cons - more often used in small rooms - in warehouses, in garages.

Heat guns are one of the most powerful tools for heating a room. They are an analogue of traditional heaters, but with a 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 indoor area 150 m2 raise the temperature to 5 – 10 ℃ . Traditional electric heaters simply do not have such power, since only industrial power networks can withstand such a load.

At the heart of the "gas guns" is the most common burner (burner), which heats the air by burning oxygen with the formation of carbon dioxide and fumes. From the combustion chamber, all this mixture is blown out with the help of a powerful fan driven by the mains.

Unlike diesel guns, in gas guns, when fuel is burned, a minimum amount of harmful substances and carbon monoxide, so they require less performance forced ventilation. But at the same time, their speed and heating power are identical. And, by the way, the design of gas guns is simpler than that of diesel ones, so they break down extremely rarely (only if the operating rules are violated), and manufacturers give a guarantee, on average, for 36 years to 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 combustible gases enter the room. Necessarily for normal operation require high-quality ventilation of the heated room.

Gun with an open burner. 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 in such a room it is extremely dangerous for a person to be

• Closed(indirect heating). The burner is closed, additionally there is an outlet for removing the exhaust gas. Such guns are less powerful and efficient, require mandatory connection to the chimney, but are absolutely safe (and they can be powerfully used even in small residential areas). As a heating element, either air heating elements or radiators (ring heaters) are used.

Heat gun of the closed type. In this case, it is installed outdoors, and warm air is supplied through a special duct.

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

Classification by type of connection

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 not all gas stations fill them (the process itself is long, requires the use of special equipment).
2. Propane. They work on a mixture of propane-butane, 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 breakdowns can be quickly eliminated independently);
• saving(heating is much cheaper than that of guns running on diesel fuel, mining or electricity, some models are even connected to the household gas distribution network);
• high power with small dimensions and weight (the average weight of the gun with the entire body kit is from 5 to 15 kilograms, depending on the power);
• there are models with support for connecting electricity through rechargeable batteries(performance does not depend on the presence of the mains);
• much safer than diesel ones.

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

But they also have disadvantages. Significant ones include:

• as a fuel - gas, in case of violation of the rules for operating the device, this will lead to fire;
• needed high-quality heated premises (otherwise, you can get poisoned with carbon monoxide);
• require regular maintenance(in particular, cleaning the gas supply system, changing filters, and so on);
• uneven heating rooms (warm air accumulates at the top, cold air sinks to the floor, the temperature difference can reach 20 degrees).

Additional functions

Of the additional functions in gas heat guns, there are:

1. System automatic arson. Operates either from the mains or as a mechanical piezoelectric element. In their absence, 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 - more.
3. Gas supply regulation. It is used to turn on the "turbo mode", when the heating element warms up in just 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 (reacting to the ambient temperature), a position indicator (if the gun accidentally capsizes, it blocks the gas supply, 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.

Also, manufacturers began to produce automatic gas guns that work on the principle of conventional electric heaters with a thermostat. That is, they turn on and off automatically, maintaining the temperature in the room at a given level. However, the response threshold of such devices is high, so you should not count on careful compliance with the temperature up to 0.5 degrees.

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

Knowing the principle of operation of the simplest gas gun, you can understand that making the same design at home on your own will not be a problem. The main thing is to choose accessories. As a body, you can use either a piece of a pipe galvanized on the outside, with a diameter of 100 mm(recommended - 200 mm), and any stove is suitable as a burner (preferably with adjustable intensity of fuel supply to the burner). All this can be purchased at a building 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 not with soldered 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 the usual one is simply installed from the back of the pipe. household fan. The main thing is to adjust the speed of the blades in such a way that the generated air flow does not lead to the burner being extinguished. Usually, 200 - 300 rpm enough.

Aluminum container as a gas gun. The advantage of this design is a 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. Choose the right body. Ideally - steel pipe diameter in 200 mm and length not less than 80 centimeters.

Step 2 Prepare a hole in the upper part of the pipe for installing a nozzle with a burner. It can be done with a step drill. Standard nozzle inlet - order 25 mm(then you can also put a water tap, but it is gas that is recommended - they are structurally different).

Step 3 Mount the burner. All this is fixed on a washer or coupling, which is tightened outside the pipe. A refractory sealant (automotive, 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 - depends on the type of burner installed) and conduct a test run. Auto-ignition in such a system, of course, is not provided, so the burner will need to be started manually.

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

Test run and performance checks are carried out outdoors, not indoors. But it should be remembered that such devices are very dangerous, therefore, without proper experience, trying to make them yourself is not the best solution. And when working with them, someone must be nearby so that in the event of any breakdown, immediately turn off the device.

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

How to choose a gas gun in the store and what to focus on

When choosing a gas gun for domestic use, you should first of all pay attention to the following parameters:

1. Power. It is measured in kW, sometimes manufacturers additionally indicate the volume of heated air for 1 hour of operation. In the first case, follow the formula: 1 kW on the 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 already in 30 minutes continuous operation of the heater. For example, the volume of air heated by the gun is 300 m 3. Accordingly, it is optimally suited for a room with a volume of 150 m 3(do not confuse volume and area - these are completely different indicators).
2. Connection type. Meaning, with a closed or open burner. The first ones are more expensive and they are used for "emergency" heating of residential premises. For other purposes, you should not buy them. Open - best option for garages, sheds, warehouses and other non-residential premises.
3. The presence of auto arson. Basically, the function is optional. Moreover, the piezo elements quickly fail, but their presence is almost 10 – 20% raises the cost of the gun.
4. Availability of additional functions. This means adjusting the fan speed, a system of sensors, temperature controllers, and so on. All of them help to automate the operation of the gun, but at the same time, manufacturers do not recommend leaving heaters of this type operating without supervision. And the presence of those same sensors also increases the cost of the final cost of the device. If you need to save money, you can buy a gun without all these sensors.
5. Food for the fan. Occurs either from 220V, or from 12V direct current. The latter option is convenient in that the gun can be used as a mobile one by launching it even in the absence of a household power supply. If such functionality is not needed, then it is better to take it with the simplest 220V engine. Even better - without brushes (such motors are very reliable and durable, but they are quite expensive).

Table 1. Key parameters of gas guns to consider when buying.

Parameter	Recommended value
Power	Not less than 1 kW per 10 m 2 of heated space
The type of gas that the gun runs on	Methane - for connecting to a household gas network, propane - for cylinders. There are also “universal” guns, but they are expensive, and often break down due to a complex technical design (2 separate valves work there simultaneously)
Auto arson	It is recommended to take without auto-ignition - such models are cheaper, their launch is not dangerous
Availability of additional sensors	Not necessary. Most of them will not be used by anyone - proven in practice
Fan motor power supply	With support for connecting to 12V, buy if the heater will be used as a mobile one. In other cases - only 220V
Closed or open burner	Closed - for heating residential premises, open - for all others

The option of using gas guns is for mounting stretch ceilings. Under the action of high temperature, the PVC fabric is easily stretched, it does not leave wrinkles and dents.

Overview of popular models

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

1. MASTER BLP 17M. Ideal for garage heating. Reliable and durable equipment, the gearbox 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. A gun Russian production. It has a small size, suitable for use in the installation of stretch ceilings or for drying walls after painting. Power - 15 kW, but the flow is narrowly directed. It has 2 stages of heating, the kit includes a hose for connecting to a cylinder (with adapters). The average price is 5.2 thousand rubles.
3. Caliber TPG-10. Also Russian-made, power - up to 10 kW, suitable for small rooms. The gearbox is collapsible, the manufacturer has provided for its complete replacement with an analogue. Also, the fan is serviced, not pressed into the bearing. But the functionality is minimal. But the cost is only 4 thousand rubles.
4. Kroll P 10. Popular model of foreign production. It works when connected to cylinders, there is a piezo ignition, a protective 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 directed, as in other models. The average price is 9.5 thousand rubles.
5. Profteplo KG-57. Heat gun of industrial type 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 a 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.

In total, a gas gun is an excellent option for quickly heating non-residential premises. For residential - not the best option, as it requires connection to the chimney. But you can make a gun yourself, all this will require only 2 - 3 thousand rubles (for all materials).

Classical heaters will not be able to provide heat to the room in the way that a gas heat gun can do. It very quickly raises the air temperature in almost any room - residential, utility, warehouse, etc. Manufacturers offer many models that can satisfy the tastes of all buyers.

You can feel the positive effect of the equipment literally in a matter of minutes if you run the device at maximum power. Such an apparatus is powered by gas, and a heat fan provides circulation of heated air. Due to its high efficiency, a gas gun for space heating is one of the economical ways to increase the temperature.

Acquaintance with modern heaters

The demand for high-quality heating systems increases significantly closer to the beginning of autumn. It is not always the timely inclusion of centralized heating or some kind of breakdown with it that can delay the onset of the heating season. A heat gun in such a case will be very appropriate.

She can also act as auxiliary equipment during construction or renovation. A hot air stream ensures that moisture evaporates quickly from almost any surface. The heated flow is obtained by burning gas coming from a cylinder or from a centralized network.

The equipment is capable of operating on both main and bottled fuel.

The device is a relatively small cylindrical device with a streamlined protected body. The frontal part is equipped with a protective grid through which the heated air jet is directed. The gas heat gun also has the following components:

• fixed power burner;
• metal multi-blade fan;
• control unit;
• metal heat exchanger;
• ignition system;
• protective thermostat;
• additional devices used depending on the model.

What are thermal gas guns?

To do right choice, having chosen the optimal gas heater, you should familiarize yourself with the samples offered in online stores or building supermarkets. Products can meet the needs of both small rooms and large buildings with a large internal cubic capacity.

With all the variety of manufacturers, a gas heat gun for residential premises is available in two versions: direct and indirect heating.

Equipment belonging to each of these groups is available for use in domestic and industrial environments. The difference lies in appearance and function.

The direct heating heater does not have high-quality filtration capable of cleaning the output stream from carbon deposits and soot. With them there is a rapid burning of oxygen in small rooms. It is permissible to use such equipment only in those places where there is effective natural or high-quality artificial ventilation.

TPG directly heated

In addition to this disadvantage, there are positive qualities:

• high efficiency, capable of exceeding 90%;
• low electricity consumption;
• reduced demand for fuel.

The gas gun of indirect heating has an annular 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:

• gas liquefaction;
• liquefaction of toxic components;
• emission of combustion products through a built-in chimney.

This type of equipment is the most environmentally friendly. 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.

Performance characteristics

In order to achieve maximum results, it is worth knowing how to properly use a gas heat gun. Manufacturers have taken care to simplify this process. The procedure is carried out according to the following scheme:

• inside working area a burner was installed, to which hydrocarbon gas fuel is supplied;
• due to the kindling devices, a flame is formed on the burner;
• fan blades pump a stream from the outside onto a heated heat exchanger;
• a blocking function that helps not to overheat the system and not to fail is provided by a thermostat;
• having brought the surrounding atmosphere to the set temperature, which is measured by the built-in thermometer, the switch breaks the electrical circuit.

According to the output power parameters and the available area of ​​​​the room, it is easy to calculate the desired value in Watt guns. To heat 1 m 2 of an apartment with average ceilings of 2.5 m, 0.1 kW of power is enough. Warm up accordingly small room in 25-30 m 2 a 3 kW device can.

Equipment device

most popular for living conditions are gas guns of mobile type. They are equipped with convenient 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. These settings are considered obsolete.

Guns on natural gas (methane) provide the necessary microclimate indoors. They can also be used in garage conditions to create an optimal temperature balance. Often, it is their builders who use them to work with stretch ceilings.

The built-in fan speeds up the air supply to the consumers. The existing thermostat limits the heating.

More noisy in operation is a heat gun on liquefied gas(propane). Sometimes you can hear her second name "gromgun". It is used as an environmentally friendly equipment not only for heating, but also for scaring away wild animals or flocks of annoying birds.

For equipment with indirect heating, the permissible noise level is 40 dB.

Modern heat guns are different maximum efficiency work - the efficiency of the device is more than 90%, which can not "boast" of any other similar equipment. It is also important that the burnt gas is not emitted into the surrounding space, 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 works only on main gas or whether it is possible to connect cylinders. In this case, the efficiency of the device is full 100%.

In order for the TGP to cope with the tasks set, it is necessary to correctly determine its power in accordance with the area and purpose of the room. Further, the thermal insulation of the room matters - if there are heat losses, 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 know the fuel consumption in order to calculate its amount in advance for smooth operation. If a power outage is possible in the area, you should pay attention to models that do not require connection to the mains - here the piezoelectric elements operate offline.

It is strictly forbidden to make repairs gas equipment by hand without special knowledge. For warranty and post-warranty maintenance and repair, you should contact specialized organizations.
