How to choose a diesel heat gun. Heat gun on diesel fuel Design and subtleties of functioning

Mankind has come up with a lot heating units acting as heat generators. These are numerous convectors, fan heaters, infrared heaters and much more. The most powerful of them are productive heat guns. They are designed for space heating. big size and are characterized by high power. Most powerful unit- This heat gun on diesel fuel. Working on diesel fuel, it generates enough heat to heat quite large volumes.

In this review, we will look at:

• Scope of diesel heat guns;
• Varieties of heat guns on diesel fuel;
• Their advantages and disadvantages.

At the very end, we will talk about the most popular models available for sale.

The principle of operation and scope of diesel heaters

A diesel fuel heat gun is a fairly versatile unit. But not only for heating residential premises. Such units are used for heating warehouses, hangars with machinery, facilities under construction, large garages and greenhouses. The principle of operation of heat guns is very simple - diesel fuel burns inside them, and the resulting heat is pumped by a powerful fan into the heated space.

Despite the use of diesel fuel, this type of heat gun cannot be called autonomous. Electricity is still required to operate the burner and blow hot air.

An interesting feature of any diesel-fueled heat guns is that they are volatile - they need electricity to operate. Low-power models can operate on 12 volts (or 24), but the vast majority require connection to a 220 volt network. Electricity here is necessary for the operation of the burner and forcing hot air into the heated rooms (for fan rotation).

The burner in any diesel gun works as follows - it sprays diesel fuel and at the same time provides air supply. The resulting fuel-air mixture ignites, creating a steadily burning flame. The heat generated in the liquid fuel heat gun is sent to the room - a powerful fan is responsible for this.

Heat guns on diesel fuel are necessary:

• For heating warehouse premises - they generate a large amount of hot air, allowing you to do without full-fledged heating;
• As a backup source of heat for heating any objects in the event of frosts that are uncharacteristic for the area;
• For heating construction sites when there is still no heating here;
• For heating hangars in which people work and equipment is stored;
• For mounting stretch ceilings- a powerful heat source is required here;
• For heating greenhouses where any crops are grown.

At the same time, a thermal diesel gun is not suitable for heating residential premises. There are two reasons for this - high performance and the need to remove combustion products.

Varieties of diesel heaters

Heat guns running on diesel fuel are represented by two large categories - these are direct and not direct heating. Let's see how the presented varieties differ from each other.

Heat guns of direct heating

Direct heating diesel gun is the simplest source of thermal energy. It is equipped with a fully open combustion chamber. Its heart is a pump with a nozzle that provides the generation of a torch. Behind him is a powerful fan. The generated heat, together with the products of combustion, is sent to a heated room. That is, there is no separate chimney here, which is a big minus.

A direct heat gun is harmful to human health, so its operation in an unventilated room is prohibited (despite the practical complete combustion diesel fuel). Yes, and where good ventilation, people will be constantly haunted by the smell of burning - there is no escape from this. Such units are most often used in open areas where there is an influx of fresh air.

There are craftsmen who manage to convert direct-type guns into indirect-type units, which will be discussed later - they are safer.

Heat guns of indirect heating

Being near a direct-fired diesel heat gun is like sniffing the smoke from a truck's exhaust pipe. Prolonged exposure to a heated room can lead to severe headaches and poisoning. Therefore, such units are used relatively rarely. But they came up with a great alternative.

The diesel heat gun of indirect heating is a more perfect and advanced device. In some ways, it resembles a liquid fuel heating boiler. Only it does not heat the coolant, but the air. The basis of such a heat gun is the same nozzle - it is placed in a closed combustion chamber equipped with a system for removing combustion products (in other words, a chimney). The rest of the design is the same.

Due to the removal of combustion products to the outside, such units can be used to heat unventilated rooms. The forced air in these guns does not come into contact with the burning torch - it seems to blow over the combustion chamber. As for burning and soot, they go to the connected chimney and do not enter the premises. Thanks to this, indirectly heated diesel fuel heat guns can be used in almost any conditions.

Despite the presence of the removal of combustion products to the outside, for the operation of units of indirect (indirect) heating, at least some kind of ventilation is still needed - oxygen for the burner is taken directly from the room.

Advantages and disadvantages

Let's see what are the advantages and disadvantages of diesel fuel heat guns. They have a lot of advantages:

• Ease of maintenance - there is no complicated diesel used in automotive equipment. The heart of these units is a simple diesel heater in the form of a nozzle with a pump;
• The heat gun may have big power- on sale there are samples with a capacity of 10, 20 or 30 kW, as well as monstrous units with a capacity of up to 150-200 kW;
• Possibility of heating large rooms in the shortest possible time - thanks to the use of efficient fans, diesel-fueled heat guns are characterized by high performance;
• Economical compared to electrical units, even long-term operation of a diesel heat gun will not lead to gigantic costs.

There are also disadvantages:

• Diesel heat guns of direct heating are unsafe for humans - they release toxic components into the air resulting from the combustion of diesel fuel;
• Energy dependence - these units cannot work without a source of electricity;
• High cost - diesel heat guns are appliances industrial use what affects their price;
• The smell of diesel fuel - with prolonged use, the smell of diesel fuel may spread in the room.

Cons are not the most serious, so they can be neglected (with the exception of the first paragraph)

Popular Models

If you want to buy a diesel heat gun, then you will need information about the most popular and popular models. Let's consider them in more detail and talk about their technical characteristics.

Before us is a fairly powerful diesel heat gun of indirect heating from domestic manufacturer. Its power is 30 kW, the performance indicator is 500 cubic meters per hour. It can be used in any premises. The fuel in it burns out almost completely, and there is a thermostat on board to maintain the set temperature.

From this article, you can find out what features a diesel heat gun used to quickly heat rooms has: the structure and types of structures, their scope and specificity of the operation process, average prices for popular models. The text provides an overview of the advantages and disadvantages inherent in these devices, descriptions of common types of breakdowns and ways to eliminate them.

With the arrival of the cold season, the problem of heating the premises arises. And this applies not only to living rooms, but also to industrial, warehouse and commercial spaces. If the building does not have centralized system heating, the lack of heat is replenished with the help of alternative heating devices. As such a replacement, you can buy an indirect diesel heat gun with suitable characteristics.

The device and principle of operation of a diesel heat gun

The heat gun is a universal device for space heating. The principle of operation of such structures is quite simple: diesel burns inside the heater, as a result of which heat is generated, which is supplied to the room by a powerful fan.

Diesel fuel is used as fuel. Some models are able to run on used and filtered oil or kerosene. Thanks to the progressive internal device these designs have high power and coefficient useful action, which reaches almost 100%. All diesel heat guns are dependent on electricity. Some low-power modifications can operate on 12 V or 24 V, but most models for normal functioning 220V required.

Electricity is used to start the burner. In addition, it is necessary for the transport of heat due to the rotational movements of the fan. The burner not only atomizes the fuel, but also contributes to the air supply. As a result of this process, a mixture is formed that is highly flammable. Thanks to this, the flame is stable.

Affordable price of diesel guns and the possibility efficient heating premises without central system heating, made these designs so popular. This type equipment is able to generate a large amount of heat, due to which the scope of its application has expanded.

Important! Solar powered guns cannot be used to heat residential areas.

Scope of diesel structures:

• heating of warehouse type premises;
• backup heating at poorly insulated facilities in cases where frosts uncharacteristic for the area occur;
• heating of construction sites where heating has not yet been installed;
• organization of heating in hangars used for storage of equipment;
• installation of stretch ceilings;
• heating of greenhouse structures used for growing crops.

In addition, you can buy an indirect heating diesel gun to organize heating in the garage.

Why is it profitable to buy a diesel gun: design advantages

Guns that heat rooms by burning diesel fuel have many undeniable advantages. They are compact in size and big weight, while having excellent technical specifications. These designs are easy to use. The mechanism is launched with just one push of a button.
The user has the ability to control the temperature in the room.

Many diesel designs have a built-in system for connecting a rheostat. The principle of operation of this mechanism is very simple. Before launching the gun, it is enough just to set the required parameter. When the room temperature reaches this value, the automatic shutdown equipment. When the temperature drops below the level of the specified mark, the structure will start on its own.

Diesel guns are economical, fuel consumption depends on the technical parameters of the device. Equipment with a power of 20 kW and a capacity of 550 m³ / h will need about 1.5 liters of diesel fuel to warm up this volume. Using such a gun, you can achieve quick results. According to the manufacturer's information, diesel devices heat up the room instantly. The air temperature of +10°C in a room with a volume of 120 m³ can be raised by a gun to a level of +180°C in 15 minutes. And this speed is not the limit.

Diesel devices are safe to operate. If the room is well ventilated, the inhalation of burnt air does not cause such unpleasant consequences as headaches and dizziness. Quality constructions are able to work in a long mode without additional refueling. The guns are equipped with tanks of large volumes, thanks to which they are able to work continuously throughout the day.

Note! The body of the structure is heated to a temperature of + 30-35 ° C maximum. Therefore, accidentally touching the gun will not cause burns.

Disadvantages of using diesel heat guns for a garage

The customer reviews left about diesel heat guns for the garage not only reflect the advantages of these designs. Sometimes they also have shortcomings that were identified by users during the operation of the device.

High noise levels are often cited as a serious hearing irritant. Although the presence of sounds is considered normal for heating equipment. Guns do not belong to the category of silent devices. Some manufacturers offer models with reduced operating noise levels. For example, the Master BLP 15M diesel heat gun produces no more than 20 dB. This figure is considered very low.

Many users find devices dependent on electrical network uncomfortable. The gun does need power for the fan and pump, and there is no way around these requirements. However, most often such structures are used at facilities where there is electrical wiring.

Among the shortcomings is also mentioned high price diesel heat guns. However, it should be noted that the cost of such devices is fully justified by their reliability and comfortable operating system. Many people are concerned about the cost of diesel fuel, which is more expensive to buy than liquefied gas in balloons. Although the fuel consumption of these devices is small.

How to choose a heat gun according to technical parameters

One of the most important technical parameters of any heat gun is the level of its performance. In the characteristics, manufacturers indicate the number of kilowatts that the gun is capable of delivering in intensive operation. You can also calculate the performance level yourself.

An average power of 1 kW is enough to heat an area of ​​10 m², provided that the ceiling height does not exceed 3 m. This indicator is conditional, since it depends on the operating conditions of the room that needs heating.

Factors that affect heating efficiency:

• wall thickness;
• availability and quality of insulation;
• condition ventilation system;
• heat leakage (frequency of opening gates or doors);
• number of windows and doorways, their size;
• outdoor air temperature;
• the condition of the floors;
• wind strength, etc.

The price of an indirect diesel heat gun is not an indicator of quality. When choosing a device, it is advisable to pay attention to powerful modifications. The higher this figure, the better. If there is a lot of heat, you can always reduce the intensity of work. And if there is a shortage of heating, you will have to buy another device, which will significantly affect the budget. For efficiency diesel heater the place of its installation also has an effect.

Helpful advice! AT large rooms it is advisable to use several heaters. Arranging appliances diagonally will be more effective than placing them along a wall.

Cold air is always heavier than warm air, so it always accumulates in the lower part of the room. Based on this, it becomes clear that installing the gun on a hill or turning its working edge up does not increase the heating efficiency. The most optimal position of the equipment is horizontal.

The performance of thermal ventilation equipment is another parameter that you should pay attention to. At diesel gun indirect heating Ballu BHDN-20 this figure is 500 m³ / h. This means that the device is able to effectively heat the specified volume of air within 1 hour.

Last but not least are the dimensions and weight of the structures. The mass of heat guns can vary between 3-30 kg. Most of them have a mobile design, so they are easy to use. The smaller the device, the easier it is to move.

Features of direct heating diesel heat guns

Direct heating guns are the simplest devices that can serve as heat sources. Such structures have open chamber combustion. A pump equipped with a nozzle is installed inside, due to which a torch effect is provided. Behind these elements is a fan. All the heat that is generated in the process of fuel processing is supplied to the room along with the products of its combustion.

1. Diesel fuel from the tank is fed into the heating filter.
2. The compressor transports fuel to the injector.
3. The diesel fuel is ignited by the glow plug.
4. A fan mounted behind the burner captures cold air from the room to the combustion chamber, where it is heated.
5. The protective grid located in the front of the device delays the flame, preventing it from penetrating outside the combustion chamber housing.
6. After heating, the air is fed back into the room.

The principle of operation of a direct heating gun is quite simple. It is efficient and understandable. However, such guns have one significant drawback. All combustion products enter the room, so it is not recommended to use devices in living rooms. Direct heated guns are suitable for open areas and spaces with a good ventilation system.

Average prices of diesel guns for space heating (direct heating designs):

Note! Using fuel with impurities will lead to injector contamination and other unpleasant consequences. Therefore, it is very important to use quality raw materials in order to avoid expensive repairs and purchase of spare parts for a diesel gun.

Consumer opinions about diesel heat guns: reviews of direct heating designs

Users of heating equipment often share their own opinions on forums. Some of the reviews can be found below:

“I have long heard about the advantages of Master diesel heat guns, so when it became necessary to purchase a heater, I did not think for a long time and made a bet on this particular manufacturer. The gun works perfectly and fully justifies the money spent on its purchase. With its help, I not only heat the garage, but also take this device with me to the dacha for the workshop.

Of course, it’s a pity that you can’t work in a room where the gun is turned on, but I don’t really need this. It takes no more than 20 minutes to warm up the room. Other than that, I'm completely satisfied with my purchase."

Sergey Kostyuk, Yekaterinburg

“I bought myself a BALLU BHDP-20 diesel heat gun. Excellent unit. For a month of operation, no failures in automation, as was the case with my previous gun. I like that the design provides the ability to adjust the pressure on the compressor that supplies the diesel. There is only one downside - full tank The device is a bit heavy.

Igor Samoilov, Moscow

“To heat the garage, a neighbor advised me to purchase a heat gun. I went through the manufacturers and models for a long time. In the end, I settled on the Master B 35 CED diesel gun. Great machine, very simple. It is economical and completely unpretentious in maintenance. I've been using it for over a year now. One filling is enough to keep the gun running all day. A 5x8 m garage warms up in 15 minutes.

Georgy Miroshnichenko, St. Petersburg

Features of indirect heating diesel heat guns for the garage, prices and reviews

This type of gun functions in much the same way as direct fired designs. The only difference is that the products of combustion, which are formed in the process of fuel exhaustion, are removed outside the room. For this, a chimney is used. Thanks to this, indirect heating guns can be used in almost any room with a sufficient level of ventilation.

In construction closed chamber combustion nozzle installed. In addition, the gun has a system designed to remove combustion products. The air blown by the fan does not come into contact with the torch. Its heating is provided by blowing the combustion chamber.

Average prices for diesel heat guns of indirect heating:

Helpful advice! Define thermal power space heating appliance can be used with this formula: Q (in kcal/h) = K × V × ΔT, where Q is required level heat output, K is a coefficient reflecting the degree of heat dissipation, V is the total volume of the room, and ΔT is the difference between the outside temperature and that required to create a comfortable indoor microclimate.

Which have sufficient technical capacity to maintain comfortable temperature. If you need to work in a cold, unheated room, then there is an excellent option for creating normal conditions in the form of a device such as a solar heat gun.

An important advantage diesel unit to maintain heat is high performance and long life without additional refueling. In principle, these are the same fan heaters, and the device is provided a heating element which is reliably protected from external influences.

How do solar heat guns work?

The interior quickly reaches the right temperature if operated with suitable technical parameters. This device traditionally consists of:

• heating element,
• safety element,
• fan,
• Corps,
• fuel tank.

If you follow the safety precautions, a diesel fuel heat gun allows you to warm up rooms of various sizes in a short time. Diesel fuel burns in the unit, the air is filled with thermal energy, and then the fan heater comes into operation, capable of driving air masses through the heating zone.

It is necessary to choose such units in which an effective output of diesel fuel combustion products is provided. Otherwise, the use of such devices can be detrimental to the room in which the equipment is located. It is necessary to create a safe design with the forced removal of harmful fumes that appear during the operation of this technique.

indirect heating

Thus, the purchased Aurora diesel gun must have necessary characteristics optimally suited for use in certain conditions.

If the equipment is indirectly heated, then it is best to use it in, since such units have a special pipe that removes exhaust gases. It is enough to fix an additional hose to the branch pipe and ensure its outlet to the street so that there is no harmful effect of fumes.

Wherein thermal energy will be almost in full be kept in the garage. This device with indirect heating is preferable to gas units, which do not always have enough safety measures to remove harmful elements. In addition, during operation, it is necessary to ensure ventilation of the room, which leads to significant heat loss.

Direct heating units

You need to know how to convert a direct-heated diesel gun in order to avoid mistakes when choosing equipment. Still, such designs are most suitable for rooms in which people spend a minimum amount of time. The operation of such a heat gun is to mix the products of combustion of diesel fuel and air, which leads to a rapid accumulation harmful substances in space. If a person stays in such conditions for a long time, it will lead to negative consequences.

When choosing, it is necessary to carefully study the parameters specified by the manufacturers in order to exclude the negative impact of the equipment on the human body.

For units with direct heating, spacious warehouses, different kinds construction and finishing works where rapid surface heating is required. Such a device will be useful if it is not possible to connect to electricity.

Infrared thermal equipment

There is also an electric diesel heat gun, which creates required temperature due to the heating of all kinds of surfaces in the room, and air masses this process does not concern. Such devices do not provide a fan heater, so the principle of operation is somewhat different from other models of diesel guns.

22 June 2015 Alexei

The diesel heat gun is a device with a very high level efficiency, used for various purposes, one of which is the heating of objects for various purposes. For greater convenience, more than one type of such equipment is offered today.

Learn more about the application

The diesel model exists in two versions, each of which is designed to solve a certain kind of problem:

• Device with indirect heating;
• Heat gun of direct heating.

The first option is used more widely, for example, for heating civil, industrial, warehouse, agricultural and domestic premises. This is due to the fact that the design provides for a chimney, through which the combustion products of the fuel are removed. That is why this type of heat gun is used in residential areas.

We watch the video, their types and the rule for choosing equipment:

But the indirect heating device is used only in industrial, agricultural and warehouse facilities. And then, only on condition of the organization of an effective ventilation system. A heat gun in this design is more efficient due to almost 100% efficiency, but even when using such equipment in non-residential premises, it requires regular ventilation.

The design and subtleties of functioning

The gun runs on liquid (diesel) fuel, which, with regular operation, makes this unit unnecessarily expensive. But as a substitute, some prefer to use kerosene. Depending on the design, the design of such equipment is somewhat different: a direct-heated diesel heat gun does not have a chimney outlet, while a direct-heated device is equipped with such an element, which determines its operation in residential premises.

Diesel model device

Diesel compact heat gun of various types consists of the following elements:

1. Burner.
2. The combustion chamber.
3. Motor.
4. Nozzle.
5. Control Panel.
6. Fan.
7. Fuel pump.
8. Fuel tank.
9. Electrovalve.

A direct-heated diesel gun delivers fuel combustion products into the room along with heated air. As a result, with a poor-quality ventilation system in such a room, you can very quickly “burn out” from a large number harmful substances.

The equipment, when turned on, starts the pump, which is responsible for supplying fuel to the combustion chamber. At the same time, the fan starts to move, due to which heated air is supplied to the outlet of the device.

Overview of advantages and disadvantages

Diesel heterogeneous compact heat gun has radical difference from analogues, which consists, firstly, in the use of liquid fuel, and secondly, in the design. The benefits include:

• High level of performance, depending on the performance of the device, the efficiency of the device can reach 100%;
• Diesel heterogeneous thermal high efficiency the gun is compact and lightweight, which is very convenient when it is necessary to transport the device and transfer it directly inside the object;
• The diesel gun is very easy to operate: just press the button to start;
• For ease of use, the design provides a rheostat to stop the operation of the unit when the desired temperature is reached;
• A diesel gun of various types can be called economical equipment;
• Considering high efficiency, it is quite natural that with the help of this device you can almost instantly warm up the room;
• A diesel gun of various types is very reliable and can function for a long time without the need for additional fueling;
• During operation, the diesel gun of different types does not heat up to high values temperatures - a maximum of 35 degrees, and also does not pose a danger to humans, if the exhaust gases are properly organized.

Despite the long list of advantages, a diesel compact heat gun of various types also has some disadvantages, however, like any other type of equipment. The disadvantages include:

• Noise effect, however, the vast majority of analogs work accompanied by noise of different levels;
• The need to use a dedicated power source to power components such as a fan and pump;
• A diesel compact heat gun of various types needs fuel control and periodic refueling;
• The cost of the device is noticeably higher than analogues, more expensive maintenance is also noted.

The high price of such equipment is not always a significant drawback, since the device will pay for its costs as it is used.

Overview of popular models

Resanta TDP-20000

A diesel gun of various types of indirect and direct heating is quite expensive. The device of this type of medium price category- This is the Resant TDP-20000 model.

Its cost is 20,000 rubles, while the user receives a high-performance unit with a capacity of up to 20 kW with direct heating and the ability to connect to a single-phase network. The design provides for a fairly capacious fuel tank - 24l.

The overall performance of the device corresponds to a hot air supply rate of 620 cc. m.

Approximately at the same price, a direct heating option is offered - ELITECH TP ​​22DB worth 19,500 rubles. The device runs at 357cc. m, produces a power of 22 kW. Fuel consumption is 1.7 l/h.

QUATTRO ELEMENTI QE-25DN

An alternative solution is an indirect heating diesel gun of the QUATTRO ELEMENTI QE-25DN model at a price of 44,000 rubles, which is noticeable more expensive than analogues. The volume of the tank is 50 liters, the power is 25 kW, and the performance level corresponds to a speed of 330 cc. m.

Given the size of the fuel tank and the high degree of efficiency of the device, it is obvious that such an option would have a rather large weight (40 kg).

As you can see, an indirect diesel heat gun will cost more, but the user can use the unit in different areas and for various purposes. However, the heating rate will be lower due to design features.

Customer opinion

The diesel compact heat gun of indirect heating, as well as the analogue of direct heating, despite the manufacturer's statement, works quite quietly. Of course, the noise level in each performance may vary, but in general there is a relatively quiet move. You can find out how quickly or slowly fuel is consumed from the reviews. But at the same time, the intensity of the device’s operation affects the combustion rate. Accordingly, for some buyers, a diesel compact heat gun of indirect heating works for a long time without refueling, while for others - a short period.

We watch the video, an overview of the models and their application:

It happens that users mark too strong smell and the appearance of soot during operation. However, priorities should be set here: either get a device with a high level of performance, or choose a technique that is less aggressive in operation (meaning the release of combustion products into the room), but at the same time more harmless to humans.

To avoid the appearance of soot, it is recommended to use only fuel suitable for a particular device. For such devices as a diesel heat gun of indirect and direct heating, this is diesel fuel and kerosene. In the case of using diesel fuel, soot may appear. Thus, to obtain highly efficient equipment, it is enough to correlate the parameters of the room and the characteristics of the selected device.

If the power of the unit does not match the volume of the room, the performance may noticeably decrease. When choosing a device, it is important to pay attention not only to power, but also to the air flow rate. This parameter is noticeably higher for direct heating versions. Accordingly, the user should first decide what is more important: heating efficiency or fresh air output at a slightly lower feed rate.

A diesel-fueled heat gun is used to quickly heat large rooms. It can also be deployed outdoors in frost to maintain acceptable temperatures in a certain area (for example, during construction in a building under construction in winter period). The main advantage of a heat gun over standard electric or oil heaters can be considered a high heat output, which allows you to quickly heat large rooms or create acceptable conditions in a small area. open area in frost. Requires diesel fuel and mains connection (for fans to operate).

More about application

The use of a heat gun directly depends on the classification of models, of which two are distinguished today:

When operating the gun, it is advisable to protect it from children and try not to approach the exit point. warm air, because this may result in minor burns.

Design and general characteristics

A thermal diesel gun runs on combustible fuel - gasoline, diesel, diesel fuel, kerosene, etc., which makes its use on regular basis costly. Some models consume less fuel without significant loss in performance, but they are also more expensive (for example, the Master diesel heat gun). Heat guns are divided into two types depending on the presence of a chimney system. Some models may require an electrical connection to operate, as this is necessary for the operation of the fan and the chimney (if any). The main components of the diesel gun:

• Burner. Fires a jet of flame that heats the air.
• The combustion chamber. Here the air is heated to high temperatures heating up the walls of the chamber.
• Motor. Needed for some mechanisms to work. Works either from fuel, or from a network.
• Nozzle for hot air outlet.
• Fan. It is necessary to create air circulation near the combustion chamber.
• Pump for pumping fuel (all liquid fuel devices have it in their design).
• Fuel tank.
• Fuel valve. Often works from a network.

Features to look out for when buying:

• Heating power. The recommended value in kW is from 3 for home use, from 20 for large rooms.
• heating method.
• Air flow rate.
• Recommended fuel to use.
• Maximum heating area.
• Fuel consumption coefficient (kilograms of fuel per hour).
• Type of food. In most cases, it is recommended to choose 220 V.

Diesel heating guns have several significant differences from similar heat guns, the two most important of which are the need for combustible fuel to operate and strong design differences, which can make repairs more or less expensive. Consider the advantages and disadvantages of a thermal diesel gun for the average consumer.

Advantages

• Heat guns on burning fuel are very productive. Warming up occurs quickly, after which the device releases warm air.
• Energy consumption is reduced to a minimum (in some models it is not required at all).
• Most models are compact, which allows them to be quickly folded and unfolded, transported.
• Easy to operate. It is only necessary to fill in the fuel and select the operating mode.
• On some models, a rheostat is provided, which allows you to automatically stop the operation of the heat gun when the desired temperature is reached.
• Medium-sized rooms warm up almost instantly, larger ones take a few minutes.
• The gun can function for a long time without refueling.
