Heat gas guns: device, selection parameters, review of popular manufacturers

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 heat gas gun successfully copes with these tasks - the unit is especially in demand when it is necessary to speed up the drying of building and finishing materials in winter, heating a garage, 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.

What is a heat gun?

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, diesel heat guns are often installed in non-residential buildings.

Heat guns operating on different energy sources can be compared when it comes to premises of similar purposes. For all their advantages, heaters using diesel fuel or waste oil have significant limitations in use

The scope of application of gas and electric heating appliances is much wider. It includes residential, office buildings, and retail sites. When properly installed and used, such heaters are safe.

Heating device under development

Heat guns work the same way as fan heaters. The air enters through the intake holes in the housing, warms up, passing through the heating element, after which it is forcefully pumped into the room, mixing with colder air masses.

The device runs on either liquefied or natural gas. However, the fan motor and control system require electricity to operate, so the heat gun actually depends on two energy sources (+)

To avoid overheating of structural components and ensure high-quality operation of devices, manufacturers install control systems. If the temperature exceeds the permissible values, the heat gun automatically turns off.

The buyer himself decides how the device will operate - from the main gas or from a cylinder. If you need to achieve mobility of the heater, you should stock up on propane-butane cylinders

The protection system is triggered when the heater overturns. Thanks to these measures, the device is safe for consumers. If used correctly, burns and fires are excluded.

A detailed overview of different types of heat guns is given in this article.

Why do experts advise buying a gas heat gun: the scope of application of the devices

This type of equipment, such as a gas gun, is in demand not only in everyday life, but also in production. The scope of application extends to heating residential and non-residential premises. Guns are used for drying individual components in industrial and automotive applications.

In addition, the functionality of gas equipment will be useful in large areas, the size of which exceeds 25 m².

Features of the operation of gas heat guns of indirect heating for the garage

Non-residential premises collect dampness, which negatively affects storage. Such premises include a garage. High humidity has a bad effect on a vehicle that sits in it for a long time. To remove dampness from the walls, as well as get rid of fungus, experts recommend purchasing a gas gun for the garage. The cost of such units is quite high, but the versatility of such designs justifies the costs, since they can also be used in the country and at home for quick heating.

A gas gun for a garage is a mobile device that, depending on its size, can either be moved or rolled to another location

The power of heating devices is in the range of 10-100 kW. If there is no ventilation system in the room, the effectiveness of a gas heat gun for a garage is reduced to zero. You cannot stay in a room with a working device for a long time, and as a result of constantly opening the gate for ventilation, all the pumped-in heat will simply go out into the street.

Using a heat gun in a garage will create conditions for normal starting of a car engine, as well as performing repair work in the winter.

In a heated room, any processes are significantly simplified and accelerated:

• sorting of tools;
• wiping the car body and glass;
• interior cleaning, etc.

Gas heat gun for the garage - the optimal choice for power, efficiency and speed of heating the room

To choose a device with optimal characteristics, you need to consider the following points:

• the material from which the garage is built (brick, stone or metal);
• quality of thermal insulation (types and features of internal and external insulation);
• the absence or presence of electrical wiring in the room (the gun will not be able to work without electricity);
• features of the ventilation system;
• total area of ​​the room;
• operations that are carried out in the garage.

Note! After using the device, the room must be ventilated for at least 10 minutes.

Features of operating a gas gun for heating rooms

There are two types of space heating devices. Some of them consume liquefied gas. Such designs may use butane or propane. Other types of gas guns for heating are universal. A component is built into their body that provides pressure stabilization. The presence of this device allows you to connect the equipment directly to the gas main.

Since during the combustion process a large volume of carbon monoxide (CO), which is deadly to humans in high concentrations, is released into the atmosphere, the heated room must have a good ventilation system

Depending on the type of fuel consumed by the device, it may have different characteristics. The gas network pressure varies between 0.015-0.02 MPa. Therefore, guns are designed for different inlet pressures. In this case, the output of the gas cylinder reducer has a value of 0.036 MPa.

The differences between the models also affect the nozzles, which may have different nozzle diameters. This design feature is due to the composition of the fuel. The caloric content of liquefied and natural gas differs significantly. The bottled version of fuel is three times more caloric than what is supplied by the highway. For this reason, the use of natural gas as a replacement for liquefied fuel is not allowed if the design of the gun does not provide for such a possibility. This information is written by the manufacturer in the instructions that come with the device.

Even if the manufacturer provides for the possibility of replacing one fuel with another, a licensed specialist from the relevant service must connect a gas heat gun to the main pipeline. There are risks associated with using this type of heating equipment. During operation, breakdowns may occur that should not be ignored.

A gas gun is a powerful and reliable equipment with high efficiency and a relatively low cost of generated heat - due to the more affordable price of gas

Gas gun repair: common types of breakdowns and causes of their occurrence

Common gas gun failures and possible causes:

1. If 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 during operation of the device - most likely, the gas line is clogged.
5. During operation, a strong smell of carbon monoxide appears - the equipment needs to be cleaned and the gas pipeline on the heat generator needs to be adjusted. You must immediately turn off the device and under no circumstances continue to use it.

Important! You should not take risks and try to repair a faulty gun yourself. Replacing original components may make operation of the device dangerous. It is better to entrust all repair and maintenance work to professionals.

The most common malfunction of both diesel and gas guns is poor quality fuel and a large amount of unburned exhaust gases

Features of operating a gas gun for suspended ceilings

A gas gun is often used for repair work. It is indispensable in cases where it is necessary to install a stretch ceiling. By uniformly heating the polyvinyl chloride film to 65 °C, this device increases the elasticity of its surface. Thanks to this, the material is easily laid on the shelf base and firmly fixed in those places where there are gaps for its fastening.

The use of a gas gun during the installation of suspended ceilings eliminates the appearance of condensation on the surface of the load-bearing wall. This feature is one of the most beneficial advantages of such repairs.

Installation of suspended ceilings is a one-time procedure. To do this, you don’t have to buy an expensive tool; renting a gas gun completely solves this problem. Many companies provide similar services, offering an extensive list of tools with different technical characteristics for any task, including the installation of suspended ceilings.

The most suitable for installing suspended ceilings are gas heat guns

What distinguishes heat guns from other heaters?

A gas heat gun has several features that distinguish it from other types of heaters:

1. Power . This is the main criterion that buyers focus on when choosing any heater. Gas heat guns are capable of heating very large areas with minimal resource consumption. The main thing is not to make a mistake with the model.
2. Possibility of creating comfort zones . A heat gun can be installed so that it will pump heated air locally - into a specific area. This is convenient for creating comfortable working conditions in workshops, heating a garage, etc.
3. Mobility . Manufacturers produce portable and stationary models. If the buyer plans to frequently transport a heat gun (for example, to install suspended ceilings), then it is better to choose a compact and lightweight device on a stand and rubber wheels.
4. Economical . In terms of efficiency, gas models are comparable to electric ones. They are slightly inferior in ease of use, but greatly benefit from efficiency: heating is several times cheaper.

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.

Unit selection

The entire range of gas products has very high operating efficiency; the fact of environmental friendliness is also important - the burned gas does not pollute the atmosphere, there are no foreign odors, which is very important for farmers involved in growing flowers and growing vegetables.

How to choose a gas-powered fan heater from the wide range of models presented? To successfully make a choice, you need to learn more about the blue fuel used, the specific features of thermal units and their design.

1. It should be taken into account that similar heaters successfully operate from the mains or from a cylinder connected to a gas heat gun. The efficiency of such a device becomes almost 100%.
2. To purchase the right product with effective performance, you need to calculate in advance how much power the unit requires. Measurements of the room are taken: you need to know its volume. You should also check the quality of the thermal insulation to see if there are any leaks. The higher the performance of a heat gun, the faster it will heat the room to the desired temperature.
3. Pay attention to the gas consumption to know approximately how long the gun will work without the first shutdown.

All gas fan heaters have a similar operating scheme; we have already discussed in detail how it works a little earlier. It is necessary to note the fact that many do not need to connect to the network, because the piezoelectric element can ignite gas without electricity.

TPG-10 kW for 7 thousand rubles is considered by experts to be the best option for those places where there is no electricity connection nearby:

• runs on propane and butane;
• productivity - 300 m3/h;
• temperature up to + 90 C°;
• gas consumption max - 0.76 kg/h;
• weight - 5.5 kg.

This gas heat gun can be used from a gas main or with a connected cylinder, in places where there is a network connection and without electricity. The Sturm GH91101 10 kW product has similar advantages; at a flow rate of 0.75 kg/h, productivity is up to 330 m3/h, and the cost is only 5,590 rubles.

Experts strongly advise users to repair gas heat guns only in special centers where there are specialists in gas equipment, in order to avoid causing irreparable damage during independent maintenance.

Features of direct and indirect heating

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.

The designs of direct and indirect heating devices differ. In the first, the air from the heating element is directly supplied to the room, and in the second, it is pre-cleaned (+)

Directly heated guns . The fan supplies air to the burner and then supplies it to the room. Along with warm air masses, gas combustion products are also released. They are not as dangerous as substances produced by the combustion of liquid fuel, but can still cause poisoning.

The advantages of direct heating guns include accessibility and high efficiency. They are significantly cheaper than indirect heating models, and their efficiency reaches almost 100%.

Devices of this design are purchased only for rooms with good ventilation. This is necessary to ensure normal air flow to the burners and prevent people from being poisoned by gas impurities (+)

Indirect heating guns . Toxic combustion products enter a special outlet, and already purified air enters the room.

These devices are safe for health, but in terms of technical indicators they are much inferior to heaters of the first type. Their efficiency is lower (82%), and some of the heat evaporates with combustion products.

Due to their reasonable price, practicality and efficiency, direct heating guns are especially popular among teams of builders and finishers. Some entrepreneurs even provide rental services for these heaters

Which gun is better to choose - direct or indirect heating? It depends on the priorities and needs of the buyer himself. It is important to soberly assess the operating conditions of the device.

If forced ventilation is organized, the choice in favor of direct heating is obvious. However, there is a fly in the ointment here: the better the ventilation system works, the higher the heat loss.

Application requirements

The operation of a gas-powered product, regardless of design features, requires a constant flow of oxygen from the ambient air for stable combustion. When the user chooses a model, these features must be taken into account.

The pricing policy depends on the size, power and brand: the more difficult the working conditions, the larger the volume of heated areas, the more expensive a gas fuel heat gun will cost.

The room where the unit is planned to be located must have excellent ventilation so that there is a constant flow of fresh air from outside. If there is no ventilation, then you need to choose a model with a thermostat that automatically turns the gun off or on, maintaining a sufficient level of oxygen. Equipping with a thermostat allows you to increase the efficiency of the product: when the optimal temperature is reached, it turns off the fan heater, turning it on only when the set temperature drops to a certain level. Products of this class are used in production, in warehouses, in the construction of buildings and for heating agricultural facilities, where people are not constantly present.

Heating device selection parameters

There are several main points to consider when purchasing a model:

1. Intended scope of application . It is necessary to decide in advance whether the heater will work to warm up the room or will be used irregularly for certain purposes (drying plaster, etc.). Depending on this, a stationary or mobile model is chosen.
2. Installation location . Take into account the specific location of the device and compliance of operating conditions with fire safety standards.
3. Power . To heat 10 sq.m. rooms (with a ceiling height of up to 3 m), approximately 1 kW of heat is needed. This is a very approximate figure, because... depending on thermal insulation, indicators can vary from 0.8 to 1.4 kW. The heater must have a good power reserve.
4. Construction type . If there are always people in a heated room, it is better not to take risks and buy an indirect heating device. For other purposes, a direct heating model is suitable.

Price also matters. Saving on gas heating can result in, at best, additional costs, and at worst, damage to human health. On the other hand, there is no need to overpay either. The best option is to choose a suitable model from a good brand at an affordable price.

How to choose a heat gas gun for heating rooms

When choosing a heat gas gun, you need to evaluate several technical parameters. Not only the capabilities of the device are important, but also the degree of its security.

Thermal power

To buy a functional and efficient gas device, you first need to evaluate its thermal power. To heat a 10 m2 room with a standard ceiling of 2.5-3 m, about 1 kW of energy is required. To select the right gun, you need to know the area of ​​the room, as well as evaluate the quality of the thermal insulation in it.

Air exchange rate

To make the air in the room warm up faster, the gas device moves it using a fan. The throughput capacity of the most powerful models is about 3000 m3 per hour. It should be taken into account that productive units require careful handling - the air at the very outlet is very hot.

Type of fuel

Heat guns can run on propane or butane. In summer you can use any type of fuel, but for winter it is better to choose a unit that operates on a mixture of hydrocarbons. Then the device will start without problems at negative temperatures.

Gas consumption

The most economical models of thermal devices consume about 0.7-2.5 kg of fuel per hour. More productive ones burn up to 7 kg in the same time. To choose the right gun, you need to take into account that to release 1 kW of thermal energy, you need to consume 0.07 kg of propane-butane mixture per hour.

Ignition system

Some guns need to be ignited with matches, but most models are equipped with piezo ignition. It is activated by pressing a special button. There are units in which the piezoelectric element is activated when the gas valve opens.

Which heat gas gun is best to choose for heating a garage?

Most often, gas devices are used in the garage. If the building is brick, then 1 kW of thermal energy is needed to heat 10 m2. For metal garages the indicators are different - at least 2 kW per 10 m2. Considering that buildings usually have an area of ​​approximately 30 m2, there is no need to purchase an expensive and powerful unit.

For a garage, it is better to buy a gas gun with a safety system - protection against overheating, valves and gearboxes. It is necessary to completely exclude the possibility of an explosion of the propane-butane mixture.

Attention! When using a heat gun, even non-residential premises must be regularly ventilated or equipped with forced ventilation.

TOP 6 manufacturers and best models

When determining the best manufacturers and models of heaters, users focus not only on technical indicators, but also on price, build quality, frequency and reasons for contacting service centers.

Ballu household appliances are produced in various countries, incl. in Russia, China and Korea. This is the case when buyers have no complaints about the quality of Chinese products

The list of the best brands includes the following:

1. Master . These are products from Master Climate Solutions, a leader in the heating equipment market. The manufacturer controls quality at all stages of equipment manufacturing, so buyers have virtually no complaints.

Some home craftsmen assemble a gas heat gun with their own hands. Detailed instructions for manufacturing and launching the unit are in the article - Do-it-yourself heat gas gun: step-by-step assembly instructions

Connection and operation

Before turning on the device, you need to read the instructions, where all the nuances of connection and use are described very clearly. You need to pay special attention to situations when you cannot turn on the device:

• with increased dust content in the air mass of the room;
• if there are vapors of explosive substances;
• the exit hole is blocked by something.

Operating rules and safety measures may vary between manufacturers of different models - please study the attached documentation before starting work.

Gas heat guns are very economical compact products, characterized by a high volume heating rate and efficiency, so they are considered by gas equipment specialists to be an ideal option for heating various large-volume areas. I would like to note that Russian heat guns are not inferior in technical characteristics to foreign brands, and their design is almost identical, so there is no point in overpaying.

The most common equipment malfunctions

Any equipment can break down, even the most expensive, high-quality and reliable one. Faulty gas equipment is dangerous, so 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:

1. Malfunction of the gas supply button . If gas flows while the button is pressed, but disappears when it is released, then there may be problems with the safety sensor.
2. The gas is not flammable . This happens if the piezoelectric element breaks down. It should be adjusted or replaced. If you need a heat gun urgently, you can ignite the gas using a kitchen lighter with a long handle.
3. No gas flows when the fan is running . The problem often occurs when the solenoid valve breaks down.
4. It is impossible to adjust the gas supply . This happens when the gas line is clogged.
5. There was a smell of gas . The cause of the problem may lie in a blockage or malfunction of the gas pipeline. You should turn off the heat gun and contact a service center.

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.

How to make a gas heat gun with your own hands

In most cases, a heat gun is used by craftsmen as a heating device for the garage. Therefore, it would be more expedient to make an indirect heating structure that is connected to the chimney system and allows you to stay in the room during its operation.

To make a gun 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.

The design of the gas gun is quite simple, so making the device will not be difficult for anyone

Do-it-yourself gas gun assembly technology

Before you start assembling the gun, you need to make sure you have a diagram. It will serve as a guide during the work process. First you need to take a pipe with a large diameter and make a couple of holes. The size of one of them is 8 cm. The 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. A combustion chamber needs to be made from a pipe with a diameter of 8 cm.

Helpful advice! In order for the combustion chamber to be firmly held in the central part of the housing, it is advisable to use plates that are welded to the pipe.

Next, the plug is prepared. It can be cut from a metal sheet. This element must cover the gap between the 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.

Heat gas gun diagram

At the next stage, all the elements of the gas gun are assembled together. To do this, you will need a welding machine and skills in handling 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.

The process of assembling a structure with direct heating is much simpler. Such a gun consists of a pipe, at one end of which a fan and burner are attached. In this case, combustion products and hot air flows will exit from the opposite side.

Which brand of heat gun is better to buy?

In the early 1990s, all products were supplied mainly from Western Europe and Asia. In the 2000s, good alternatives in the field of climate control technology development began to appear on the CIS market. And for more than 15 years, some Russian brands have successfully competed with their foreign colleagues, while adhering to a gentle pricing policy. Who they are, these leaders, you will learn from this list:

• Resanta – the year of birth of the Swiss company is 1932. It is a leader in the manufacture of heaters for both commercial and private use. It provides a 3-year warranty on all its products.
• Ballu is a leading manufacturer of climate control equipment for the home and industry, which began operations in 1980 in Thailand. The sales geography of its products covers all of Europe, Asia and partly even North America.
• Frico is a European brand that creates equipment for monitoring and managing room temperature. All products have AMCA and ISO quality certificates.
• Master is a manufacturer of air treatment systems for both large and small areas. It offers both direct and indirect heating models.
• Kraton is one of the few Russian brands that produces climate control equipment from the “budget” category and at the same time of European quality. The company has been operating since 1999 and has representative offices in 80 cities of Russia.
• Zubr is another Russian manufacturer of construction tools and equipment that has its own laboratory for pre-sale testing of products.
• Interskol is a company producing construction equipment and tools, which has its own factories and showrooms. This is the only trademark in the CIS in its niche that is officially recognized by the EU.
• Sibrtech is a company created in Russia; when producing goods, it takes into account the needs of the country's consumers. All products are made from high quality materials and alloys.

Additional functions

Additional functions in gas heat guns include:

1. Automatic ignition system . 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 . This functionality allows you to adjust the power of the air flow. For small rooms – less, for large ones – more.
3. Adjusting the gas supply . 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 of 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.

This model has 4 sensors that allow the device to automatically turn on/off to maintain the set temperature in the room

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 careful adherence to temperatures down to 0.5 degrees.

Such sensors are responsible for automatically turning off the gun when an emergency occurs. But they fail quite quickly, especially when using low-quality fuel

Principle of operation

“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.

The principle of operation of the simplest gas gun

Unlike diesel guns, gas guns produce a minimal amount of harmful substances and carbon monoxide during fuel combustion, so they require lower forced ventilation performance. 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 down extremely rarely (only if operating rules are violated), and manufacturers provide a guarantee of, on average, 3–6 years for such devices.

Closed and open guns

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

• Open (direct heating). They have a simpler design, the burner is open, all combusted gases enter the room. For normal operation, they require high-quality ventilation of the heated room.

Open burner gun. A more common option, but it can only be used in rooms where there is normal supply ventilation. Otherwise, carbon dioxide and carbon monoxide accumulate, 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.

Closed type heat gun. In this case, it is 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 ones - in residential ones 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.

Connects to the household gas distribution network. But at the same time, its power is quite low, since in such gas sources the final pressure is low

Why a gas gun?

The main criterion when choosing mobile heating equipment is the scope of its use. It is worth immediately noting that the gas gun works on the principle of a stove. The air is heated when natural gas is burned. Accordingly, when it operates, the amount of oxygen in enclosed spaces quickly drops. It is definitely not suitable for offices and residential premises. Requires good ventilation. Otherwise, it has a number of advantages.

• Economical. Compared to electrical energy, gas is much cheaper.
• Versatility. Electric guns with a power of up to 5 kW are highly efficient when working in rooms with an area of ​​30-50 m2. Ideal for a small office, garage warehouse. More powerful devices will require a mains voltage of 380 V, which is not available everywhere. Gas-powered equipment also requires access to the network. But for the fan to operate, 220 V, which is familiar for home conditions, is sufficient. For most popular models, main and liquefied gas in cylinders is suitable. Both natural and butane.
• Functionality. They are also used to dry rooms after construction work, warming cars in severe frosts, and working with polymer materials.
• Fast heating. The devices do not require preheating.
• High efficiency during operation, since the fuel burns completely, releasing heat.

Some buyers have questions about the safety of using gas-powered guns. Modern models are equipped with protective sensors and stop the fuel supply when the flame overheats or goes out. If you follow the rules of safe use, they will become good helpers for a long time at work, in the garage or in the country.

Review of popular models

Analyzing information on thematic forums, we can identify the following popular gas burners among Russian consumers:

1. MASTER BLP 17M . Ideal 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 m2. 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 . Russian-made gun. It is small in size and 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). The average price is 5.2 thousand rubles.
3. Caliber TPG-10 . Also made in Russia, power up to 10 kW, suitable for small spaces. 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 of 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 m3 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 m3 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.

MASTER BLP 17M, one of the best selling models

We recommend our article on the topic - Heating boilers for a private home, where we examined the principle of their operation and how to start the heating system step by step.

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

Criterion No. 1: type of heating

Gas-powered heaters belong to one of two groups according to the type of heating. Indirect heating heat guns are designed to create an optimal temperature microclimate in residential buildings or rooms where people are temporarily located. In models of this type, the heat exchanger is designed in such a way that fuel is burned in it first, and then combustion products, which are highly toxic. For proper operation of an indirect heating heater, a separate exhaust pipe is not required - properly functioning ventilation is sufficient.

The direct heating heat gun differs from the first model in the principle of fuel combustion. Toxic waste is not completely destroyed in it, so natural ventilation is not enough here. To effectively remove combustion products, an exhaust pipe is provided, which is connected to a stationary chimney.

Important! The main advantage of indirect heating heat guns is their high level of efficiency, tending to 100%.

Caiman is a representative of a fundamentally new type of equipment, which implements an indirect infrared heating system. This is an expensive professional-grade device, which is recommended for heating business facilities, large warehouses, military and industrial bases, and construction sites. An infrared heating element emits a large amount of heat, the characteristics of which resemble solar energy - the rays do not just heat the surface, but penetrate inside, reaching the deep layers of objects.

Pros of the device:

• “radiant heat” for maximum efficient heating;
• competent fuel consumption system;
• neutralization of toxic combustion products - up to 20 times less carbon monoxide than direct-heated guns;
• low noise level;
• adjustable emitter angle.

Minuses:

• high price;
• massive and difficult to transport.

Important! Gas guns require not only fuel, but also power from the electrical network - the electricity is used to maintain the operation of the built-in fan.

Frequent breakdowns and their elimination

Common problems with gas guns and possible causes:

1. If 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 requires cleaning and adjustment of 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.
