From this article you can find out what features a diesel heat gun used for quickly heating rooms has: the structure and types of structures, the scope of their application and the specificity of the operating process, average prices for popular models. The text contains 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 space heating arises. Moreover, this applies not only to living rooms, but also to industrial, warehouse and retail spaces. If the building does not have centralized system heating, the lack of heat is compensated with the help of alternative heating devices. As such a replacement, you can buy an indirectly heated diesel heat gun with suitable characteristics.

Design and principle of operation of a diesel heat gun

A heat gun is a universal device for heating rooms. The principle of operation of such structures is quite simple: diesel burns inside the heater, resulting in the formation of heat, which is supplied to the room by a powerful fan.

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

Electricity is used to start the burner. In addition, it is necessary for transporting heat due to the rotational movements of the fan. The burner not only atomizes fuel, but also promotes air supply. This process results in a mixture that is highly flammable. Thanks to this, the flame is stable.

Affordable price of diesel guns and possibility efficient heating premises deprived central system heating, made these designs so popular. This type of equipment is capable of generating a large number of heat, due to which the scope of its application has expanded.

Important! Guns powered by diesel fuel cannot be used to heat residential premises.

Scope of application of diesel structures:

• heating of warehouse-type premises;
• backup heating in poorly insulated facilities in cases where frosts uncharacteristic for the area occur;
• heating construction sites where heating has not yet been installed;
• organization of heating in hangars used for storing equipment;
• installation of suspended 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 light weight, while having excellent technical characteristics. These designs are easy to use. The mechanism is started with just one press 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 operating principle of this mechanism is very simple. Before launching the gun, you just need to set the required parameter. When the room temperature reaches this value, the equipment will automatically turn off. If the temperature drops below the specified level, the structure will start on its own.

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

Diesel devices are safe to use. If the room is well ventilated, inhaling burnt-out air does not cause such unpleasant consequences as headaches and dizziness. Quality designs capable of long-term operation without additional refueling. The guns are equipped with large-volume tanks, thanks to which they are able to operate continuously throughout the day.

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

Disadvantages of using diesel heat guns for garages

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

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

Many users find the dependence of devices on the electrical network inconvenient. The gun really needs power for the fan and pump, and there is no way around these requirements. However, most often such structures are used in facilities where there is electrical wiring.

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

How to choose a heat gun based on technical parameters

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

On average, a power of 1 kW is enough to heat an area of ​​10 m², provided that the ceiling height does not exceed 3 m. This figure 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;
• state ventilation system;
• heat leakage (frequency of opening gates or doors);
• number of windows and doorways, their size;
• outside air temperature;
• condition of the floors;
• wind force, etc.

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

Helpful advice! In large rooms it is advisable to use several heaters. Arranging appliances diagonally will be more effective than placing them along the 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 upward does not increase the heating efficiency. The most optimal position of the equipment is horizontal.

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

Not least important 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 designs have an open combustion chamber. A pump equipped with a nozzle is installed inside, which ensures a torch effect. A fan is located behind these elements. All the heat that is generated during 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. Diesel fuel is ignited by a glow plug.
4. A fan installed behind the burner draws cool air from the room into the combustion chamber, where it is heated.
5. The protective mesh located in the front part of the device traps the flame, preventing it from penetrating beyond the combustion chamber body.
6. After heating, the air is supplied back into the room.

The operating principle of a direct heating gun is quite simple. It is efficient and clear. However, such guns have one significant drawback. All combustion products enter the room, so it is not recommended to use the devices in living rooms. Direct heating 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 contamination of the injectors and other unpleasant consequences. Therefore, it is very important to use high-quality raw materials to avoid expensive repairs and the purchase of spare parts for a diesel gun.

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

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

“I have long heard about the advantages of Master diesel heat guns, so when the need arose to purchase a heater, I did not think twice and relied on this manufacturer. The gun works great and is completely worth 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 on, but I don’t really need that. It takes no more than 20 minutes to warm up the room. Otherwise, I am completely satisfied with my purchase."

Sergey Kostyuk, Ekaterinburg

“I bought myself a BALLU BHDP-20 diesel heat gun. A wonderful unit. For a month of operation, there were no failures in the automation, as was the case with my previous gun.

Excellent device, very simple. It is economical and completely easy to maintain. I've been using it for more than a year now. One refill is enough to keep the gun working all day. A 5x8 m garage warms up in 15 minutes.”

Georgy Miroshnichenko, St. Petersburg

Features of diesel indirect heating 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 combustion products that are formed during the process of fuel exhaustion are removed outside the room. A chimney is used for this. Thanks to this, indirect heating guns can be used in almost any room with a sufficient level of ventilation.

A nozzle is installed in the design of the closed combustion chamber. In addition, the gun is equipped with a system designed to remove combustion products. The air pumped by the fan does not come into contact with the torch. Its heating is provided by blowing into the combustion chamber.

Average prices of indirectly heated diesel heat guns:

Helpful advice! The thermal power of a room heating device can be determined using this formula: Q (in kcal/h) = K × V × ΔT, where Q – required level thermal power, 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 the one required to create a comfortable microclimate in the room.

To provide targeted heating, heat guns are most often used. Their feature is their high power in supplying air masses at a certain temperature. This is due to wide application of this equipment in the construction sector and industry. A properly selected diesel heat gun can heat concrete, maintain an optimal microclimate in a production area, and also protect plants in a greenhouse from hypothermia in winter.

Operating principle of heat guns

The organization of the working process in any heat gun provides the possibility of activating a fan, which provides air supply. IN in this case this task is achieved through the energy generated in the diesel fuel combustion chamber. The design of the unit includes a tank for filling diesel fuel or kerosene. Through a special filter, the mixture enters the sump, and then the pump pumps it into the nozzle for further use. Typically, a fan is located at the rear of the equipment, which supplies cold air masses into the combustion chamber, distributing diesel from the nozzle into it. Ultimately, fuel combustion occurs, and the already hot masses are directed to the target object. According to this scheme it is built general principle operation of a heat gun on diesel fuel, but there are some differences in the process depending on design features one model or another. At the very least, there are fundamental differences in the operation of the two types of such installations - with direct and indirect heating. It is worth familiarizing yourself with these types of heat guns in more detail.

Types of heat guns

Models with direct heating are distinguished by the fact that during operation they emit a combustion product directly into the operating area - this could be, for example, a production room or a construction site. Modifications with indirect heating provide for the removal of combustion products outside the boundary of the working object. Obviously, direct heating has serious limitations in terms of use. In particular, such equipment cannot be used in residential premises. In exchange for this inconvenience, the user receives better performance.

In turn, an indirectly heated diesel fuel heat gun can also be used in rooms where people are located. Its design includes a mechanism for removing combustion products, which is connected to the chimney channel through a special pipe. That is, in the process of work heat flows get rid of burning, spreading throughout the room or workshop in a relatively pure form. True, the operation of such models also requires the organization of a ventilation system in the room, since the unit will process oxygen.

Main characteristics of the equipment

Among the main technical and operational parameters of heat guns, it is worth noting power, volume of delivered air and fuel consumption. As for power, this figure is in the average range from 10 to 80 kW. For residential premises, installations with a power potential of 15-25 kW are usually purchased. In industry, more efficient units with a power of about 200 kW are used. In order to ensure future savings, one should also take into account the volume of the combustible mixture, due to which the thermal fuel will operate. Fuel consumption varies on average from 1 to 6 l/h. The higher the power, the more voracious the heat generator. Depending on the area of ​​the room, the volume of warm masses that the installation will distribute is selected. This figure can be 200 or 3000 m 3 / h. For a living room, an installation with an initial volume value will be sufficient, and production facilities, warehouses and construction sites are served by high-performance heat guns.

In addition to this, many emphasize the benefits of safety and limit thermostats, which increase the safety of equipment operation.

How to choose the best option?

It's not just character that needs to be taken into account intended purpose, but also dimensions and availability requirements additional functions. You can build on your strength potential and performance indicators. This will help determine the principle of operation of the gun - with or without the removal of waste combustion products. In accordance with the size of the room, the dimensions that a diesel heat gun can have are determined. It is not difficult to install this unit with your own hands, but in the case of models that provide gas removal, it may be necessary to additionally equip the structure with pipes and adapters for the chimney. It would also be a good idea to calculate in advance the need to have electronic systems control with heat gun control.

Most heat generators operate in intensive mode, which increases the importance of technical measures for their maintenance. The user must primarily take care of regular cleaning and replacing filters. In particular, the air filtration element, which filters out fibers and fluff, should be renewed every 500 hours of operation. As a rule, it changes at the end of each season. To avoid the need to run on diesel fuel as part of the power filling, you should regularly maintain the fan. In a dirty state, it complicates the work process, which increases the load on the generator. Therefore, the fan should be cleaned at least once a season.

Conclusion

In most cases, heat guns are massive structures that also have impressive weight. Despite this, such equipment is quite practical to use and performs its tasks without any problems. However, depending on the design, diesel heat guns may impose special requirements on the place of use. This mainly applies to models with indirect heating, the operation of which is possible only in rooms with organized ventilation. But we also shouldn’t forget about the specifics of using units that directly emit combustion products into environment. It is advisable to use such models outdoors or in production workshops, where the presence harmful substances will not pose a danger.

Humanity 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 high-performance heat guns. They are designed to heat rooms big size and are characterized by high power. The most powerful unit is a diesel heat gun. Running on diesel fuel, it generates enough heat to heat fairly large volumes.

In this review we will look at:

• Scope of application of diesel heat guns;
• Types of diesel heat guns;
• Their advantages and disadvantages.

At the very end, we will tell you about the most popular models on sale.

Operating principle and scope of application of diesel heaters

A diesel fuel heat gun is a fairly versatile unit. But not for heating residential premises. Such units are used for heating warehouses, hangars with equipment, objects 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 will still be required to operate the burner and blow hot air.

An interesting feature of any diesel fuel heat guns is that they are volatile - they require 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 is needed here to operate the burner and pump hot air into the heated rooms (to rotate the fan).

The burner in any diesel gun works in the following way– 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 a liquid fuel heat gun is sent into the room - it is responsible for powerful fan.

Diesel fuel heat guns are required:

• For heating warehouse premises - they generate a large amount of hot air, allowing you to do without full heating;
• As backup sources heat for heating any objects during the onset 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 installation suspended ceilings– a powerful heat source is required here;
• For heating greenhouses where any crops are grown.

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

Types of diesel heaters

Heat guns running on diesel fuel are represented in two large categories - direct and indirect heating devices. Let's see how the presented varieties differ from each other.

Direct heating heat guns

A direct heating diesel gun is the simplest source of thermal energy. It is equipped with a completely open combustion chamber. Its heart is a pump with a nozzle, which generates a torch. There is a powerful fan behind it. The generated heat, along with combustion products, is sent to the heated room. That is, there is no separate chimney here, which is a big disadvantage.

A direct heating heat gun is harmful to human health, so its operation in an unventilated area is prohibited (despite the almost complete combustion of diesel fuel). Yes, and where there is good ventilation

, people will be constantly haunted by the smell of burning - there is no escape from it. Such units are most often used in open areas where there is a flow of fresh air. There are craftsmen who manage to convert direct-type guns into units indirect type

, which will be discussed further - they are safer.

Heat guns of indirect heating

Standing next to a direct-fired diesel heat gun is like smelling smoke from the tailpipe of a truck.

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

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

Advantages and disadvantages

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

• Ease of maintenance - there is no complex diesel engine used in automotive equipment. The heart of these units is a simple diesel heater in the form of a nozzle with a pump;
• A heat gun can have great power - there are samples on sale with a power of 10, 20 or 30 kW, as well as monstrous units with a power of up to 150-200 kW;
• Possibility of heating large rooms in the most short time– thanks to the use of efficient fans, diesel heat guns are characterized by high performance;
• Cost-effective – compared to electric units, even long-term operation of a diesel heat gun will not lead to enormous costs.

There are also disadvantages:

• Directly heated diesel heat guns are unsafe for humans - they release toxic components into the air resulting from the combustion of diesel fuel;
• Volatility dependence - these units cannot operate without a source of electricity;
• High cost - diesel heat guns are industrial devices, which affects their price;
• Smell of diesel fuel – with prolonged use, the smell of diesel fuel may spread in the room.

The disadvantages are not the most serious, so they can be ignored (with the exception of the first point)

Popular models

If you want to buy a diesel heat gun, then you will need information about the most popular and in-demand models. Let's look at 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, its productivity is 500 cubic meters per hour. It can be used in premises for any purpose. The fuel in it burns almost completely, and there is a thermostat on board to maintain the set temperature. One of the important functions is protection during extinction - if the flame suddenly disappears, the unit will immediately turn off.

For heating hangars, tents, sports and exhibition halls, agricultural and livestock complexes, as well as other large industrial and construction facilities for various purposes used heat gun. It is a mobile powerful air heater. A special heating element is installed in the gun body, heating up to a high temperature. The air passing through it, pumped by the built-in fan, exits into the room powerfully air flow high temperature. The combustion chamber is made of heat-resistant alloy steel. The outer casing almost never heats up due to the large air flow quickly passing through the diesel heater. The wear-resistant outer coating of the gun body is designed for long-term operation of the diesel air heater.

Depending on the heating method heating element There are 4 types of heat guns:

- diesel heat guns;

Gas heat guns;

Heat guns without power control;

Direct heating heat guns.

Available in two types diesel heat guns : direct and not direct action.D excellent thermal cannon direct action can be used to heat air only in the absence of people, animals, etc. in a heated room. This requirement is due to the fact that the air repeatedly passing through the heat gun loses oxygen and is saturated with the products of its combustion.

Indirect heating air heaters are characterized by the absence of emissions of combustion products into the heated room, and can be used in places where people are located. Diesel guns indirect-acting units have a special heat exchanger, which ensures that harmful emissions are removed from the heated area, while clean heated air enters the workroom. Powerful indirect air heaters operating using diesel fuel have a burner torch control system. For achievement complete combustion fuel, a mechanism for regulating the flame is provided. Also, all units are equipped with overheating protection. Automatic maintenance of the set temperature is ensured by a built-in thermostat, which is equipped with most models of diesel air heaters.

Diesel heat gun, enough fuel, with non-stop operation, for 8-16 hours, depending on the model and the volume of the fuel tank.

Diesel heat gun during operation, it creates a powerful directed stream of hot air, the outlet temperature of which reaches 255 degrees (depending on the model and type of product). The heat transfer process of the air heater occurs almost instantly. High performance and forced air circulation when using a heat gun allow you to quickly heat and maintain the set temperature in a large room.
