The unit structure includes a metal housing, which is able to protect the structure from various damages.

Heating parts are fireproof. All models are lightweight, which allows them to be moved to any location. Diesel designs are often in demand during the construction of various objects. They are used when it is necessary to quickly dry the surface. Liquid fuel designs can be indirectly or directly heated. In the first method, a withdrawal is performed flue gases from the premises. The operation of such devices is accompanied by oxygen burnout, so they are used for outdoors

or in rooms with flowing ventilation.

How to choose a diesel heat gun? Please note that when starting the heat gun on diesel fuel combustion products are released. Manufacturers offer two types of such devices: direct heating

and indirect.

• When choosing a design, the following factors are important:
• room area;
• availability of fuel raw materials;
• the ability to remove harmful impurities, and ventilation;

how it will be used: constantly or periodically.

Diesel units contain a burner, combustion chambers, a fuel tank and a fan. Some products are equipped with wheels for ease of movement. Fuel is supplied using a pump.! Helpful information

When choosing a model, base your calculations on the following indicators. For 10 sq. m. you will need about 0.9-1.5 kW.

Nuances of choosing a direct heating diesel heat gun A diesel fuel heat gun has a simple direct heating mechanism. An electric motor and a fan are located inside the product. Using pumping unit

When diesel fuel burns out, it warms up air masses that are removed from the fan. The heated air is distributed in space. And the smoke masses disperse into the inside of the building. Therefore, such devices can be used outdoors or in buildings with a good ventilation system.

Note! Such models are suitable for short-term work. For example, dry the work surface with construction work or warm up a frozen engine.

How to choose a diesel indirect heating heat gun?

In installations indirect heating, in addition to the main elements, there is also a heat exchanger. The fuel is transferred from a special container to the combustion chamber. In this case, the flue gases do not mix with the air masses from the fan, but exit through the chimney structure to the street.

When the device is turned on, the heat exchanger warms up and heats the air. At the outlet similar devices can emit from 50 to 110 degrees of heat. This technique is used in factories and warehouses, since harmful gases do not pass inside. In modern equipment, combustion tanks are made of stainless steel.

Some devices are equipped flexible hoses, allowing the release of a warm flow to specific area.

Helpful information! You can connect a thermostat to the equipment, which is mounted inside the building. In this case, the equipment will be able to maintain the required temperature and will produce heat for about 17 hours.

Models of infrared diesel heat guns

The infrared diesel heat gun installation does not include a fan heater. Such heaters warm up not the atmosphere, but surrounding objects using infrared irradiation.

The burner with diesel raw materials warms up infrared emitter, which heats surfaces and objects in the room. are silent, since their device does without a fan.

How to calculate the power of equipment?

An important factor influencing preference for a particular product is power. This figure ranges from 20 to 220 kW. To calculate the unit with what power is required, you need to calculate the volume of the room. To do this, determine the height, width and length of the walls. You should also know the quality of the thermal insulation provided. This coefficient will differ for non-insulated brick and wooden buildings, as well as in buildings with increased thermal insulation. To carry out calculations, it is worth determining the difference in temperature values ​​inside and outside the building. In this case, the power of the device is calculated as follows: the volume of the room is multiplied by the temperature difference and the thermal insulation coefficient.

Waste oil heat gun models are an excellent solution for heating any room.

A heat gun is one of the fastest and most powerful types of room heating. For selection desired design heat gun, let's do a brief analysis.

What is a heat gun

In our climatic conditions, even with enhanced insulation of the room, using modern finishing insulation, using heat-insulating plaster- you can’t do without heating.

A heat gun, like conventional heaters, consists of a heating element, a housing and a fan. Since such equipment can be installed indoors comfortable temperature in a matter of minutes - heat guns use a very powerful fan.

The fan forces air to pass through the heating element, thereby creating a powerful heat flow.

Heat guns are characterized by their mobility, which allows them to be moved from one place to another.

Externally, this unit resembles a cannon, has a cylindrical body, is located horizontally or at a slight upward angle.

Very often, one might say mainly, heat guns are used on a construction site or industrial facility.

How to correctly calculate the required thermal power of a gun

Before purchasing this unit, you need to know the size and volume of the room in which the heat gun will operate, and whether there will be people there all the time.

It is necessary to decide what type of fuel the consumer will use - electricity, gas or diesel.

Any good seller will ask leading questions before offering a model.

For example: the volume of the room, depending on this volume, the required performance of the gun is selected. At average height the ceiling is 3 meters, one kilowatt of heat generated is enough to heat approximately 8 to 12 cubic meters. The larger the room, the more powerful the equipment should be.

There are formulas by which you can independently calculate the required thermal power.

Thermal power (kcal/hour) is equal to Vx^TxK. V is the volume of the heated room, i.e. product of width by length and height (cubic meters);

^T - difference in outside air temperatures and required temperature indoors, in degrees Celsius;

K - dissipation coefficient, depends on the type of structure and insulation of the room.

Simplified wooden structure or corrugated construction metal sheet without thermal insulation has a coefficient of 3 to 4;

a simplified building design made of single brick masonry with a simplified design of windows and roof, with little thermal insulation, has a coefficient of 2 to 2.9;

standard design with double brickwork, with a small number of windows, a standard roof, average thermal insulation, has a coefficient from 1 to 1.9;

improved design, brick walls double insulated, limited number of double glazed windows, thick floor base, high quality roof thermal insulation material, thermal insulation is high - coefficient from 0.6 to 0.9.

One kilowatt is 860 kilocalories per hour.

But any theoretical calculations do not always give an accurate result, since much depends on the circumstances.

For example, if the building has very high ceilings, it is recommended to use infrared heaters, they do not heat the air, but the surface of objects, the heat from which is transferred to the air.

To choose wisely heat gun, you need to know heating methods air flow this technique.

Guns are divided into several types: electric, diesel and gas guns.

Each type has its own characteristics and advantages.

Electric heat guns

If it is possible to connect to electricity, you can install electric heat guns.

The so-called fan heaters are popular today in everyday life and construction.

Such guns are mobile, easy to use, do not require additional fuel, and operate from the mains.

Models with power up to 5 kW. powered by 220 volts, more powerful ones by 380 volts.

Heat is generated when current passes through a high-resistance conductor, and a fan blows the heat away from the heating element and carries it to its destination.

Currently, most heat guns use heating elements - heaters in which a wire is placed inside the tube; the tube itself is made of austenitic or non-austenitic steel.

Tubes made of non-austenitic steel heat up less, are more durable, but carry a lower thermal load per unit area. For stronger heating, you need to use longer heating elements.

Tubes made of austenitic steel oxidize during operation, microcracks appear, this can lead to the risk of explosion of heating elements.

Electric guns are relatively small in size, take up little space, but their performance is not very high, and are not suitable for heating a room with high humidity(baths, saunas, etc.).

Electric guns consume a lot of electricity, so such models are used in short-term operation.

Gas heat guns

Such models weigh little and are inexpensive.

The power usually ranges from 10 to 100 kW, but more powerful ones are also available.

The only problem is fuel, liquefied gas It is not sold in cylinders everywhere; it is difficult to stock up on fuel, since a number of requirements apply to storing gas in cylinders.

Gas guns are economical; when burned, they practically do not emit gas harmful substances, but ventilation is still necessary.

The consumer should know that the gas pressure in the line or in the cylinder must correspond to the selected heater model.

For the simplest model with a power of 10 kW, a pressure of 0.5 bar is required, the more powerful the gun, the greater the pressure.

For safety reasons, many guns are equipped with flame control and protection against overheating of the housing.

Gas guns are sensitive to low temperatures and may operate unstably in severe frosts.

Diesel heat guns

Diesel guns are similar in operating principle to gas guns; they use diesel fuel as fuel.

It has a number of disadvantages, namely: quite high weight, since the gun has to be transported along with the tank.

The design of diesel guns is more complex.

Fuel is supplied to the combustion chamber by a fuel pump or compressor - all this leads to higher costs, and additional components require additional maintenance.

Diesel fuel is more contaminated with impurities than gas, so you can turn on such guns in non-residential premises with ventilation.

But such guns also have a lot of advantages.

Fuel is available, its consumption is very economical, one refueling is enough for continuous operation within 10-15 hours.

Transportation of diesel fuel is safe, heating installation not tied to gas main, the power is the same as gas guns.

The diesel gun can operate over a wide thermal range.

Some models are classified as indirect heating devices; for this purpose, the guns use an additional circuit - a heat exchanger.

Hot gases pass through a heat exchanger and exit to the street through the chimney, the heat is removed using a fan.

The efficiency of such guns is lower, the price is higher, but there is no need to worry about ventilation and airing.

Such models are designed for heating large volumes in work areas.

It is necessary to understand that the operation of diesel and gas heat guns still requires a small amount of electricity to power the fan and automation system, but if necessary, the gun can be powered from a small generator.

When choosing a heat gun, you should decide for what purposes they will be needed: heating a house, garage, greenhouse, or for construction needs.

In any case presented, for the right choice electric heater, you need to decide on its power, design characteristics and manufacturer.

Technical properties and characteristics of heat guns

Heat guns for home

The first thing you should pay attention to are parameters suitable for normal and quality work heat gun. It is necessary to select according to power and suitable electrical voltage.

For the first characteristic, there are two main calculation options. A simple definition is that for heating 10 sq.m. rooms need at least 1 kW electrical power. And if you have a room of 4x6 meters, simple calculations will show that you need to purchase a heat gun with a power of at least 3 kW.

We got this indicator like this: 4 * 6 = 24 sq.m., taking into account that the electrical power reserve must be at least 20%, we calculate: 2.4 * 1.2 = 2.88 kV. The closest value will be 3 kW, and this is what you need to select for heating this room.

The second calculation method is more accurate, and we recommend using it when choosing a heat gun for your home. In this case, the formula does not take into account the area of ​​the room, but its volume and the thermal conductivity coefficient of all walls. And the formula takes on next view: P= (V*dT*Kt)/860, where:

V is the volume of the room, calculated as the area multiplied by the ceiling height, m3;

dT - temperature difference between the room and the environment;

Kt – thermal conductivity coefficient. An indicator from 0.6 to 1 is for walls with good thermal insulation. With average thermal insulation - from 1 to 2. With poor thermal insulation - from 2 to 3. Old houses - from 3 to 4.

860 is the number of kcal in 1 kW.

Required thermal power

To make the essence of the calculation more clear, let's consider it with an example. You have decided to purchase an electric gun to warm up your car. The garage volume is 4x6 meters, the ceiling height is 3 meters. The temperature inside the building is +15C, outside -20C. The temperature difference is 35C. The garage is insulated quite well, we select the thermal conductivity coefficient 1. As a result of all the indicators, the formula takes the following form: 72*35*1=2520 kcal/hour.

To convert the value to kW, you need to divide it by 860. This turns out to be 2.93 kW. Taking into account the required reserve, you need to choose a heat gun of at least 3.5 kW, and this will be quite enough.

It should be noted that there is currently conditional classification all thermal devices by power. It is generally accepted that up to 5 kW these are heat fans, and above this power – heat guns.

We also note that the all-stamped impeller creates a more powerful flow warm air. If you need a good electric heater for repairs, for example, for the installation of a suspended ceiling, we recommend choosing a device with just such a fan.

We wrote above about how to choose the right heat gun for your home and garden. We hope that this information was useful and interesting for you. And in the future, you can easily choose the electric heat gun you need.

A heat gun is one of the most powerful and fast devices for heating a room. The units have several types, differing in energy carrier. Now there are several types: gas, multi-fuel, diesel, electric, diesel and infrared. Let us present the differences and advantages of each of these types.

How to choose an electric heat gun?

The heating element in it is a heating element; there are several models with a power ranging from 1.5 to 50 kW. Low-power models operate from the network. They can heat industrial and warehouse premises, as well as residential buildings. Compared to a gas gun, this type is safe and environmentally friendly. The heating element does not burn oxygen compared to a coil. The operation of powerful models is dependent on a two-phase or three-phase network. The built-in safety system prevents the gun from overheating - the thermostat turns off the device when it heats up to the maximum temperature value.

There are portable devices and stationary ones. For the dacha and small rooms it is better to choose compact devices that can be rearranged in different rooms. Under stationary devices you need to allocate a place and secure them.

Important factors when choosing such a gun are:

• Thermostat. Its presence will allow you to manage the performance and efficiency of the device.
• Frame. Among plastic, composite and metal, it is better to give preference to the latter. They are stronger; if the electricity suddenly turns off, the heated heating element will not harm the steel case, while its plastic counterpart can melt and cause a fire.
• Thermostat. Its presence indicates that if the device overheats, it will automatically disconnect from the power source and prevent a fire hazard.
• Service center. When purchasing a device well-known company, the warranty card can be presented in the event of a breakdown to the center, and they will carry out free repairs. By purchasing cheap option, there is a possibility that if there is a problem, you will have to pay dearly to restore it.

The shape of the heat gun also influences the choice, so it is more rational to purchase a cylindrical body for utility rooms and garages, which are winter time needs to be warmed up quickly. Here are the options rectangular shape more convenient to install on residential dachas and at home - they are less dangerous and their mesh heating element dries the air less than the spiral installed in cylindrical counterparts.

When in doubt when choosing between an electric and gas heat gun, it is better to choose the first type, it is safer and does not generate waste in the form of exhaust gases, this is especially important when installing the device in a residential building. In addition, the electrical device can operate continuously for a long time.

WITH different models BALLU BHP guns can be viewed in the video review:

How to choose a gas heat gun?

For housing, it is better to buy an indirect heating gun, which has a system for removing exhaust gases; they negatively affect animals and people living in the house. It is used as fuel in devices natural gas. When it burns out, it enters the room and pollutes the air. The efficiency of such guns is 100%. They are optimally used in rooms where many people gather or for heating greenhouses.

The stationary version of such guns is connected to a centralized gas pipeline, but their mobile versions operate from gas cylinders.

The main advantage of these guns over other types is their low fuel consumption when heating fairly large areas.

The only inconvenience during their operation may be shortages of fuel; not in all regions you can buy gas in cylinders, and you can purchase it in large volumes without security special conditions storage is impractical.

When using gas guns, practically no gas is released into the room, but ventilation is still necessary. When choosing them for your home, you should focus on the gas pressure in the system or cylinder - it must match the declared indicator in the technical characteristics of the selected unit.

How to choose a diesel heat gun?

They are designed for rooms with good ventilation, and can also be used to warm the car in very coldy. Diesel heat guns are enclosed in a heat-resistant housing that does not heat up. To control the fuel supply, a fuel level indicator is provided.

Diesel heat guns differ favorably from electric ones in that they consume a small amount of fuel, produce a large flow of warm air and are equipped with a fuel level control system. Diesel appliances are also capable of heating large rooms and workshops due to their high efficiency, which is 10 times greater than that of appliances powered by electricity.

Compared to its gas counterpart, it does not emit substances harmful to others and is safe for others. Both of these types of guns are primarily used for heating production areas, but diesel ones are more powerful.

If the device is needed for periodic heating of a room, for example, a cottage, it is better to choose gas model, it will cost less, and besides, one gas cylinder is enough to provide heat to a small house for a week.

The principle of operation of diesel heating devices is similar to the operation of a blowtorch, only everything happens much simpler and without harm to nature. They come in direct and indirect heating. The first type releases waste substances, while the second comes with a special pipe for removing gases and can be used in residential premises.

Indirect-action diesel guns are preferable for housing, since they remove combustion products outside the home. Direct-acting devices mix heated air with combustion products inside themselves, and then discharge them into a heated room, so it must be well ventilated.

You can see the device clearly in the video below:

Other heat gun options to choose from

Depending on your goals, you can also choose the following types of drug:

• Infrared heat gun. The design of such guns does not have a blower fan; instead, the heat flow is pumped using infrared radiation. Such devices heat only a certain area of ​​the room - where they are installed. Most often, they are used to quickly dry applied plaster, especially in cold weather or high humidity. They are also indispensable during installation. suspended ceilings. This type of gun is absolutely safe for people and the environment.
• Water heat gun. Its heating device is made in the form of a heat exchanger through which it enters hot water. Such devices are most often connected to a central water system, which significantly increases their productivity. The unit can be installed on the ceiling or hung on the wall. It is compact and suitable for any room, chosen by many due to its high productivity.
• Multi-fuel guns. In them, a flow of warm air is obtained as a result of burning previously used oil. In such units, a special pump system is installed, through which waste oil passes into the combustion chamber. A warm air flow enters the room from it. The efficiency of such devices is almost 100%, they are presented with high power. Models without a thermostat can work continuously for up to 15 hours. On devices where it is available, work can last 24 hours. Various oils and even mixtures of them can be used as fuel.

Criteria for choosing a heat gun for the garage and home

Before purchasing this heating device you need to calculate the area that it should heat, decide on the frequency of its use, and what fuel is beneficial for it to use specifically for your home. For housing, you need to choose a device with a built-in pipe for removing combustion products beyond its boundaries, as well as with a thermostat and protection against overheating. Among the numerous models, it is worth choosing from gas, infrared, water and electric.

The garage belongs to non-residential premises, but it still provides ventilation, since it is visited infrequently, it is quite rational to buy small models, but the main thing is that they are of indirect action - after all, small volumes of this room are quickly polluted by exhaust gases.

Video: How to choose the right heat gun?

The following video with a specialist will discuss the features and types of heat guns for choosing the right model:

Among the varieties of heat guns under consideration, the most popular are electric models, this can be explained by the ease of their maintenance, the lack of fuel - they operate on current in the network. But for warehouse and production premises They are not suitable; diesel and gas options are purchased for these purposes.

How to choose an electric heat gun given the wide range on the market? After all, it will be an excellent heating agent for the home, cottage and other premises. To make the right choice, you must follow the following recommendations:

1. First you need to decide on the type of gun. There are stationary and mobile guns. To properly install a stationary gun, you need to use the services of installation workers. As for the mobile heat gun, it is enough to read the operating instructions.
2. Next, we determine the type of gun (in the form of a cylinder or rectangle). Rectangular heat guns contain specialized heaters in the form of mesh material.
3. Choose which type of air heating is most preferable for you. If you need a gun to heat an area where an animal or person is present, then you should purchase thermal electric guns 12 kW, heating of which is indirect.
4. It is also worth deciding on the power of the heating device. The greater the manufacturer's power, the greater the productivity. It is worth choosing the power depending on the area of ​​the room where heating is needed.

What should you pay special attention to when purchasing an electric heat gun?

When you choose a heat gun, special attention should be paid to the following parameters:

• The air heater must be professional level if you use the gun for a long enough period of time. Therefore, it is preferable to choose those guns where the air heater is able to operate without interruption or stop for a long time. The break can be no more than two hours.
• Also, the air heater must be equipped only with a metal casing. Likewise, the mesh grille should be made of metal. They help maintain warmth for a long time during a sudden power outage;

• An electric heat gun of 50 kW or other voltage must have a heating level regulator and air flow switches. This way you can control the gun yourself.

What are the advantages of electric guns?

An electric heat gun is a device for heating any room. Basically, heat guns are needed to heat rooms such as a garage or a room where renovation work is being carried out.

The choice of an electric heat gun also depends on its advantages. It has the following advantages:

• An electric heat gun can be installed in unventilated areas;
• The device can operate for a fairly long period of time;
• No need to add fuel;
• No open flame during operation;
• No malicious or unpleasant odors are not released into the atmosphere during operation;
• Safe room heating device;
• It is possible to automatically adjust the room temperature if you purchase a gun with a thermostat;
• You can use it immediately after switching on, there is no need to warm up;
• Thanks to minimum parameters can be used in any room.

A review of electric heat guns will give a basic understanding of the types of devices and what basic characteristics they have. After such information it will be much easier to decide on the choice of heater.

Basic models of electric heat guns

Electric heat guns have undeniable advantages compared to gas or liquid fuel similar devices. The only drawback of such a heater is the fact that if the electrical network is disconnected, the device will not work.

Such devices have excellent advantages. They can save electricity by using low power during operation at sufficiently high temperatures. Main technical characteristics of this model are the following indicators:

• Productivity is 120 m3h;
• Supply voltage 220 V;
• The mass of the device is 1.68 kilograms;
• Rated current is 9.1 A;
• The air temperature increases to 70 C;
• The device parameters are 175x175x190 mm.

Another popular variety is the TEP 2000 electric heat gun. This device is needed for heating small rooms. It is convenient to transport with the help of a handle. Heating element installed in the form of a round heating element, which will heat the room to the desired temperature in a matter of seconds. The heating element 2000 device can operate in one of two possible modes (ventilation without heating and ventilation with full heating).

The main technical parameters of the TEP 2000 heat gun are the following data:

1. The maximum power is 2 kW;
2. Air consumption is 200 cubic meters;
3. Weight is 4 kilograms;
4. Maximum supply voltage 220 V;
5. There is a power plug.

The electrical circuit of a heat gun is a picture of everything that happens technological processes during the operation of the heat generator. It also contains information on using a heat gun. Each type of gun has its own electrical circuit.

This scheme includes data such as:

• Thermostat capsule;
• Heated filter;
• Protective thermostat;
• Transformer;
• Engine.

All of the above components have common element in the form of a thermal switch. The peculiarity of a heat gun is its efficiency. The higher the efficiency of an electric heat gun, the more performance it has. Consequently, the device will work much better.

Where can I get my electric heat gun repaired?

There comes a time when the device fails, in which case it is necessary to urgent repairs electric heat gun. Today, there are a huge number of service centers that are ready to provide their repair services. They will carry out all repair work competently and efficiently.

After the device arrives at the workshop, service centers will initially carry out an accurate diagnosis, after which they will tell you what the cause of the problem is. The cost of repairs will depend on the number and complexity of the work. Repair work pass only with the use quality material and modern instruments.

The main faults that 12 kW electric heat guns have are presented in the following list:

• The heat gun blows, but the room is not heated. This is due to such a reason as the lack of necessary voltage on the nichrome spiral, which is responsible for heating the room.
• Broken nichrome spiral. This phenomenon is quite common for an electric heat gun, since the spiral is open.

• The heat fan does not do its job and does not heat well. Cool air enters the room. Most likely the plug has a poor or damaged contact that is arcing.
• If when you turn on it appears bad smell from the hot coil of the heater, and the motor does not spin, this means that it is burnt out or filled with dust.

What are the possible causes of electric heat gun malfunctions?

The causes of heat gun problems can depend on many factors. Today they can be varied, for example:

• Violations of the rules for using an electric heat gun;
• Poor quality of electricity until the device is completely worn out;
• Constant power loss.

If you find that your heating device is malfunctioning during operation, then you definitely need to contact a service center that will fix all the problems. Most common cause breakdowns are malfunctions of the heating elements. The first sign of a malfunctioning heating elements is the incoming cool air, as a result of which the room does not heat up.

If an air heating element is installed in a heat gun, then such guns are non-repairable and non-repairable electrical devices. Consequently, repairs can only be performed if the heating element needs to be completely replaced.

In addition to heating elements frequent breakdown electric motors are exposed. It happens that the heating element works properly, but the electric motor malfunctions. Masters in service center First of all, make sure there is incoming voltage.

What additional breakdowns can occur with an electric heat gun?

In addition to the main components of the gun, elements such as switching devices, circuit breakers, magnetic starters. Such malfunctions are rare; mainly electric motors and heating elements break due to heavy load.

You should not troubleshoot any problems with the device yourself. You need to contact a highly qualified technician who will quickly and efficiently fix all problems.
