To maintain the temperature of the room in the winter in the absence of central heating, you can use a gas gun, which has a high efficiency and saves energy. 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

The demand for such a modern unit increases several times during the heating season, provided there is no 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 a different appearance, principle of operation.

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 annular 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 the mechanism is the presence of a chimney, which complicates the mobility and transportation of a gas-type gun.

How does it work

Before using the gun at home, you need 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 pumps cold air from the environment, directs it 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 with a gas cylinder, which is problematic 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 gun works on gas, a suitable model can be ordered in 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 a 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 specified 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 the catalogs contain a huge number of items of interesting design with unique technical characteristics. 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, during the combustion of fuel, a minimum amount of harmful substances and carbon monoxide is formed, so they require less 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). They have a simpler 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 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, 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 living quarters). 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 of the breakdowns can be quickly eliminated independently);
• saving(heating is much cheaper than that of guns on diesel fuel, "working off" or electricity, some models are completely 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 a 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 an ordinary household fan is simply installed from the back of the pipe. 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, a steel pipe with a diameter of 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 recommended to use a gas tap - 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 in order to immediately turn off the device in case of any breakdown.

You should not use self-made heat guns for heating. They are better suited for quick drying of 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 - the 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.

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 gas burners among Russian consumers can be distinguished:

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. Russian-made gun. 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).

gas heat gun It is used for heating, drying and ventilation of non-residential premises. The unit runs on liquefied (butane, propane) or natural gas and is used in large rooms as the main source of heat and additional.
Any diesel or gas heat gun will be effective at such facilities as warehouses, construction sites, hangars, storage facilities, industrial premises. Due to the products of fuel combustion released into the atmosphere, which are harmful to humans, it is not recommended to use these units in living rooms, houses, offices and other places of permanent residence of people without proper air ventilation.
The design of the gas gun consists of a heat exchanger where the gas is burned, and a powerful fan that creates a directed air flow. Rugged metal housing protects internal parts. As a rule, guns have an automatic or piezo ignition system, as well as an effective safety system that controls the size of the flame.
Gas guns have a simple principle of operation - gas from a cylinder or gas pipeline is fed into the combustion chamber, where it is ignited by an automatic or piezoelectric element. When the gas is burned, the heat exchanger is heated, which transfers its heat to the air flow coming from the fan. The heated air is dispersed throughout the room.
Some models of gas guns use infrared heating. There is no fan in this design, but there is a reflector (special screen), which is heated by a gas burner. The reflector transmits heat in the form of infrared rays to surrounding objects, which, in turn, reflect this heat and heat the room.

• direct heating gas gun- when gas is burned, combustion products are emitted directly into the room where it is installed. Such a gun has a simple design and high efficiency. This type is the most harmful to humans and can only be used in places where there are no people: hangars, construction sites (drying the walls after painting), etc.
• indirect gas heat gun- displays the products of combustion through a chimney connected to it to the street. This type is safer and can be used in rooms with non-permanent stay of people. Cons: lower efficiency and the need to lay a chimney.

• mobile gas guns;
• stationary.

mobile models have compact dimensions and, as a rule, 1 or 2 pairs of wheels and a handle for easy transportation around the room. The power of the guns during heating is in the range of 10-100 kW and consumes gas economically. The gas price for such heat guns is affordable, anyone can purchase this model. Such a mobile gas heat gun for the garage is perfect. When operating a mobile gun, care must be taken with the use of gas.
Stationary heat guns are large and are installed or fixed in one place, for example, on the ceiling. The maximum thermal power of such devices is 580 kW, and the productivity of heated air is up to 40200 sq.m per hour. They can heat large rooms in a short time.

Power. This value determines the size of the room to be heated or ventilated. The calculation of power is based on 100 W per 1 sq. m. For large objects, as a rule, high-power industrial heat guns are used, which consume a lot of gas.
Fuel consumption. This indicator depends on the power - the higher it is, the faster the gas will be consumed. The maximum flow rate is 305 liters per hour. Fuel for gas guns is supplied from a gas pipeline or from cylinders.
The weight. This indicator is directly affected by power - the higher it is, the more gas is consumed and the thicker the walls near the combustion chamber. Mobile gas guns can weigh from 4 to 60 kg, industrial ones - more than 60. Wheels are provided for easy movement.

This is a portable or stationary device for heating air. Heat guns are used for heating spacious rooms - houses, hangars, workshops and production shops.

The devices are easy to use and affordable. An additional plus: they economically consume energy resources.

The heaters got their name because of their 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 source of energy on which they work: gas, electricity, diesel fuel, waste oil. Since diesel fuel and mining have a specific smell, they are often installed in non-residential buildings.

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

What distinguishes heat guns from other heaters

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

1. Power. This is the main criterion that buyers are guided by when choosing any heater. Gas heat guns are able to heat rooms of a very large area with minimal resources. The main thing is not to make a mistake with the model.
2. Ability to create comfort zones. The heat gun can be installed so that it will pump heated air locally - into a certain area. This is convenient for creating a comfortable working environment in workshops, etc.
3. Mobility. Manufacturers produce portable and stationary models. If the buyer plans to frequently transport the heat gun (for example, to install stretch ceilings), then it is better to choose a compact and lightweight device on a stand and rubber wheels.
4. Economy. In terms of efficiency, gas models are comparable to electric ones. They are slightly inferior in terms of ease of use, but they win a lot in terms of 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 heat the air even in poorly insulated rooms. Under such conditions, heat quickly escapes, but while the device is in operation, a comfortable temperature is always maintained in the selected zone.

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.

Most common equipment problems

Any equipment can break, even the most expensive, high-quality and reliable. 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 done by a service center

Consider the causes of equipment malfunctions:

1. Malfunctions 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. Gas does not ignite. This happens in the event of a breakdown of the piezoelectric element. It should be adjusted or replaced. If you need a heat gun urgently, you can ignite the gas with a long-handled kitchen lighter.
3. No gas flow when fan is running. The problem often occurs when the solenoid valve breaks down.
4. Unable to adjust 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 the clogging or malfunction of the gas pipeline. Turn off the heat gun and contact the service center.

When operating a heat gun, follow the manufacturer's recommendations. The equipment should be cleaned and washed in time, bearings should be lubricated and, if necessary, worn parts should be replaced.

An indirect heating gas gun can be a very good helper in home life and in some other areas. But in order for it to be useful, you need to familiarize yourself with the general description, learn more about the types and models of such equipment. It is equally important to know, however, the main criteria for choosing gas guns.

Peculiarities

First you need to figure out what it is - an indirectly heated gas gun. This device uses the energy released during the combustion of gas to heat the premises. The power of gas guns is very high, because it is not limited by the power of electrical networks and is associated only with fuel consumption. In addition, the absence of the need for electricity increases the mobility of such equipment. Modern gas guns have a long service life and are characterized by high thermal efficiency.

They are much more environmentally friendly than diesel counterparts.. In addition, natural gas (or rather, a propane-butane mixture) is significantly cheaper than diesel fuel. When it burns, almost no soot, soot appears. But we must remember that any gas equipment - source of increased danger.

The choice, connection and use of such equipment should be made as responsibly as possible.

Just burning the gas is not the best solution. In the room then harmful products of combustion will accumulate. Everyone who has ever seen what happens when a gas stove works for 2-3 hours or more with the windows closed will agree with this. Indirect heating means that the firebox is completely isolated from the surrounding room. The intake of fresh air and the removal of flue gases occurs through a special chimney.

Types and models

A heat gun with the removal of combustion products to the outside can operate on different types of fuel. Some models work only on propane or butane. Other modifications are more versatile and allow you to choose any type of gas. This is achieved using a special pressure stabilizer. The gas pressure in the main network is 0.015-0.02 MPa, and the gas cylinder reducer ensures equalization of this pressure to 0.036 MPa.

The difference in the energy value of liquefied and natural gas also forces the use of nozzles with different characteristics. Now it is useful to see what models modern manufacturers offer for a garage and other similar premises. Has a very good reputation MASTER GREEN 310 SG. The mass of the device is 128 kg. Its dimensions are 1.5x0.628x1.085 m; thermal power reaches 75 kW.

There is another model from the same manufacturer - Green 470 SG. It already develops a power of 134 kW. The mass of the device is 219 kg. It will take 1.74x0.75x1.253 m. But this is not a record either.

The model can demonstrate the highest performance Ballu Biemmedue SP 150B Metano. It produces approximately 174 kW of heat. The air exchange rate can reach 10,000 cubic meters. m in 60 minutes. To operate the system, you need a current of 380 or 400 V. Other options:

• current consumption 2.34 kW;
• sound volume during operation up to 77 dB;
• electric gas ignition;
• automatic shutdown in case of excessive heating;
• gas consumption 13.75 kg in 60 minutes;
• the main fuel is propane-butane;
• The burner is included in the delivery.

How to choose?

It is worth considering from the very beginning - gas guns of indirect heating are not cheap. They cost several hundred thousand rubles. In addition, the total number of such models is small. Unambiguous preference should be given to products of the well-known company Master. It is very reliable and lasts quite a long time. The optimal power is calculated by multiplying the volume of the room by the difference between the street temperature and the desired indicator, and then by the thermal insulation coefficient.

So, 125 kW of power allow you to heat at least 3200 square meters. m and no more than 4100 sq. m of a new building with excellent thermal insulation. Therefore, buying “the most powerful, so that it is guaranteed to be enough” does not make sense. It should also be taken into account that the more powerful the device, the louder it works.

Connection to cylinders is justified only where it is impossible to use main gas.

But wherever there are solid pipelines, it is better to use them. The presence of a thermostat is very useful. When there is a thermostat, the gun will not heat the room after reaching the required parameters. Important: you should find out what specific type of fuel the gas gun is designed for. This will avoid many very unpleasant surprises.

• protective shutdown in case of a fall or blockage to one side;
• flame control;
• strength of the metal case;
• dimensions (determining the possibility of installing the device in a particular place);
• design (relevant for use in public places).
