Diesel gun thermal: characteristics of heating devices
With the arrival of the cold season, there is a problem of heating the premises. Moreover, this applies not only to living rooms, but also to industrial, warehouse and commercial type spaces. If there is no centralized heating system in the building, the lack of heat is compensated with the help of alternative heating devices. As such a replacement, you can buy an indirect heating diesel heat gun with suitable characteristics.
The device and the principle of operation of a diesel heat gun
The 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 fuel is used as fuel. Some models are capable of running on used and filtered oil or kerosene. Thanks to the progressive internal structure, these designs have high power and efficiency, which reaches almost 100%. All diesel-powered heat guns are dependent on electricity. Some low-power modifications can operate from a voltage of 12 V or 24 V, but most models require 220 V for normal operation.
Electricity is used to start the burner. In addition, it is necessary for the transportation of heat due to the rotational movements of the fan. The burner not only sprays fuel, but also contributes to the supply of air. As a result of this process, a mixture is formed that is easily ignited. Thanks to this, the flame is stable.
The affordable price of diesel guns and the possibility of efficient heating of rooms devoid of a central heating system have made these designs so popular. This type of equipment is capable of generating a large amount of heat, which has expanded the scope of its application.
Important! Guns running on diesel fuel cannot be used for heating residential premises.
Scope of application of diesel structures:
- heating of warehouse-type premises;
- backup heating on poorly insulated objects in cases when uncharacteristic frosts occur for the area;
- heating of construction sites where heating has not yet been supplied;
- organization of heating in hangars used for equipment storage;
- 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 it is profitable to buy a diesel gun: advantages of designs
Guns that heat rooms by burning diesel fuel have many undeniable advantages. They are compact in size and light in weight, while having excellent technical characteristics. These designs are easy to operate. The mechanism is started with just one push of a button.
The user has the ability to monitor 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 necessary parameter. When the indoor air temperature reaches this indicator, the equipment will automatically turn off. If the temperature drops below the level of the specified mark, the design will start on its own.
Diesel guns are economical, fuel consumption depends on the technical parameters of the device. Equipment with a capacity 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 information stated by the manufacturers, diesel devices instantly warm up the room. The air temperature of +10 ° C in a room with a volume of 120 m3, the gun is able to raise to a level of +180 °With 15 min. Moreover, this speed is not the limit.
Diesel devices are safe to operate. If the room is well ventilated, inhaling burnt-out air does not cause such unpleasant consequences as headaches and dizziness. High-quality designs are able to work in a long mode without additional refueling. The guns are equipped with tanks of large volumes, so that they are able to work continuously throughout the day.
Pay attention! The body of the structure is heated to a temperature of +30-35 °With a maximum. Therefore, an accidental touch to 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 do not only reflect the advantages of these designs. Sometimes there are shortcomings in them that were identified by users during the operation of the device.
High noise levels are often mentioned 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 a reduced level of operating noise. For example, the diesel heat gun Master BLP 15M produces no more than 20 dB. This indicator 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 it will not work around these requirements. However, most often such structures are used at 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 operation system. Many people 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 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 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.
The 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 of the ventilation system;
- heat leaks (frequency of opening gates or doors);
- number of windows and doorways, their size;
- outdoor air temperature;
- condition of the floors;
- wind power, etc.
The price of an indirect heating 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 indicator, 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. The efficiency of the diesel heater is also influenced by the place of its installation.
Useful advice! In large rooms, it is advisable to use several heaters. Placing the devices 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 up does not increase the heating efficiency. The most optimal position of the equipment is horizontal.
The performance of ventilation equipment is another parameter that should be paid attention to. The Ballu BHDN-20 indirect heating diesel gun has this indicator of 500 m3/h. This means that the device is able to effectively heat the specified volume of air within 1 hour.
The dimensions and weight of the structures are not the least important. The mass of heat guns can vary between 3-30 kg. Most of them have a mobile design, so they are convenient to use. The smaller the device, the easier it is to move it.
Features of direct heating diesel heat guns
Direct heating guns are the simplest devices that can serve as heat sources. Such structures have an open combustion chamber. A pump equipped with a nozzle is installed inside, which ensures the effect of a torch. A fan is placed behind these elements. All the heat that is generated during the processing of fuel is fed into the room together with its combustion products.

The principle of operation of the direct heating gun is quite simple. It is effective and understandable. 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 outdoor areas and spaces with a good ventilation system.
Average prices of diesel guns for space heating (direct heating designs):
|Brand||Model||Power level, kW||Price, rub.|
|Master||B 35 CEL DIY||10||21590|
|B 35 CED||10||21790|
|B 70 CED||20||31260|
Pay attention! The use of fuel with impurities will entail 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.

Features of indirect heating diesel heat guns for garage, prices and reviews
This type of cannon functions in almost the same way as direct heating designs. The difference lies only in the fact that the combustion products that are formed during the fuel processing 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 has a system designed to remove combustion products. The air that is pumped by the fan does not come into contact with the torch. Its heating is provided by blowing the combustion chamber.
Average prices of thermal diesel guns of indirect heating:
|Brand||Model||Power level, kW||Price, rub.|
Useful advice! It is possible to determine the thermal power of a device for heating a room using this formula: Q (in kcal / h) = K × V × ΔT, where Q is the required level of 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 outdoor temperature and that which is required to create a comfortable microclimate in the room.
Consumers’ opinion about diesel heat guns: reviews of indirect heating designs
Reviews from forums about indirect heating guns:
“I use the KROLL MAK15 cannon and am completely satisfied with this unit. No more than 1.5 liters of diesel fuel is consumed per hour in maximum operating mode. It was the economy that attracted me to this model. The tank is designed for 30 liters. In winter, I use only winter diesel, otherwise the fuel just settles. There are no problems with the launch.”
Evgeny Doroshenko, St. Petersburg
“After the accident on the heating main, which provided heating in the garage, I had to buy a diesel heat gun Master BV77E. The unit, of course, is dimensional. The length of the body exceeds 1 m, and the weight of the structure with an empty tank is neither more nor less than 55 kg. Fortunately, the manufacturer provided for the possibility of convenient transportation, which I could not but appreciate. A trolley on wheels is included with the device. The construction is quite strong. After 3 months, there are no breakdowns, backlashes and extraneous sounds. The only thing I don’t like is the need for a constant fuel check. And filters need to be changed from time to time. Otherwise, the device is great.”
Konstantin Nalivaiko, St. Petersburg
Features of repair of diesel guns for space heating
Repair maintenance of an installation running on diesel fuel can result in a significant amount. Only one diagnostic procedure costs about 1000 rubles. For this reason, many owners of garages and warehouses resort to self-repair of structures.
How to repair a diesel heat gun yourself
If the warm air does not move, the electric fan drive may be faulty. The repair involves stripping the terminals, checking the winding on the motor (an analog tester is suitable for this), as well as insulation. Sometimes the breakdown is so serious that a superficial correction is not enough. In such cases, one thing remains – engine replacement.
An important part of the design are the nozzles. The full functioning of the entire heating system depends on the quality of these elements. These parts rarely break down, and new elements to replace the failed ones can be bought at any store.
Much more often, the need to repair a diesel gun arises due to clogging of the filter. To eliminate this breakdown, it is enough to open the body of the structure, unscrew the plug and get the contaminated element. After washing with pure kerosene, the filter is ready for further operation. Before installing this part in place, it is advisable to blow it with a jet of compressed air.
Rules for the safe operation of diesel appliances
When operating diesel appliances, it is very important to adhere to the basic safety requirements. A container filled with fuel must not be placed closer than 8 m from sources of open fire and any heating devices.
Important! It is not allowed to use gasoline instead of diesel. Volatile components of this substance increase the probability of an explosion several times.
The room with a working gun must be left at the first appearance of these symptoms:
- severe dry mouth;
- painful and unpleasant sensations in the nose and throat, as well as the eye area;
- headache that appeared suddenly;
The presence of carbon monoxide in a closed room negatively affects the condition of people suffering from diseases of the cardiovascular system, lungs. The presence of pregnant women and patients with anemia in the room where the gun is working is not allowed.
Due to their efficiency, diesel guns are so in demand on the market. Observing the basic rules of operation, you can avoid health problems. Otherwise, the use of a diesel gun is not dangerous. A high-quality device with suitable technical characteristics can provide a garage or warehouse with effective heating for many years. The design of these devices is so simple that most of the breakdowns that occur during operation can be eliminated by the owner without the intervention of specialists.
