Diesel heat gun: characteristics of heating devices
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 commercial spaces. If the building does not have a centralized heating system, the lack of heat is replenished with alternative heating appliances. As such a replacement, you can buy an indirectly heated 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: a diesel engine burns out inside the heater, as a result of which heat is generated, which is supplied to the room by a powerful fan.
Diesel oil is used as fuel. Some models are capable of running on waste and filtered oil or kerosene. Thanks to their progressive internals, these designs have high power and efficiency that reaches almost 100%. All diesel heat guns are dependent on electricity. Some low-power versions can operate on 12V or 24V, but most models require 220V for normal operation.
Electricity is used to start the burner.In addition, it is necessary to transport heat due to the rotational movements of the fan. The burner not only atomizes the fuel but also aids in the air flow. This process creates a mixture that is highly flammable. This makes the flame stable.
The affordable price of diesel guns and the ability to efficiently heat rooms without a central heating system made these designs so popular. This type of equipment is capable of generating a large amount of heat, due to which the scope of its application has expanded.
Important! Diesel fuel cannons cannot be used to heat residential premises.
Scope of application of diesel structures:
- heating of warehouse-type premises;
- backup heating at poorly insulated facilities in cases where frosts uncharacteristic for the area come;
- heating of construction sites on which heating has not yet been supplied;
- organization of heating in hangars used for storing equipment;
- installation of stretch ceilings;
- heating of greenhouse structures used for growing crops.
In addition, you can buy an indirectly heated diesel cannon for heating your garage.
Why is it profitable to buy a diesel gun: the advantages of designs
Cannons that heat rooms by burning diesel fuel have many undeniable advantages. They have compact dimensions and low weight, while they have excellent technical characteristics. These designs are easy to use. The mechanism is started with just one push of a button.
The user has the ability to control the room temperature.
Many diesel designs have a built-in rheostat connection system. The principle of this mechanism is very simple. Before starting the gun, you just need to set the required parameter. When the room temperature reaches this value, the equipment will automatically shut down. When the temperature drops below the level of the indicated 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 capacity of 20 kW and a capacity of 550 m³ / h will require about 1.5 liters of diesel fuel to heat this volume. Quick results can be achieved using such a gun. According to the information declared by manufacturers, diesel devices instantly warm up the room. The air temperature of + 10 ° С in a room with a volume of 120 m³ can be raised to a level of + 180 ° С in 15 minutes. Moreover, this speed is not the limit.
Diesel devices are safe to operate. If the room is well ventilated, breathing in the burnt air does not cause such unpleasant consequences as headaches and dizziness. High-quality structures are capable of operating in a long mode without additional refueling. The cannons are equipped with large-volume tanks, thanks to which they are able to operate continuously throughout the day.
Note! The structure body is heated to a temperature of + 30-35 ° C maximum. Therefore, accidentally touching the cannon will not cause burns.
Disadvantages of operating diesel heat guns for a garage
Customer reviews for diesel heat guns for a garage not only reflect the benefits of these designs.Sometimes they also contain flaws that were identified by users during the operation of the device.
High noise levels are often cited as a serious hearing irritant. Sounds are considered normal for heating equipment though. Cannons do not belong to the category of silent devices. Several manufacturers offer models with reduced operating noise levels. For example, a Master BLP 15M diesel heat gun produces no more than 20 dB. This figure is considered very low.
Many users find the dependence of appliances on the electrical network inconvenient. The gun really needs power for the fan and pump, and these requirements cannot be circumvented. However, most often, such structures are used at facilities where there is electrical wiring.
Among the disadvantages is the high price of 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 are concerned about the cost of diesel fuel, the purchase of which is more expensive than purchasing liquefied gas in cylinders. Although the fuel consumption of these devices is low.
How to choose a heat gun according to technical parameters
One of the most important technical parameters of any heat gun is its performance level. In the characteristics, manufacturers indicate the number of kilowatts that a gun can produce in an intensive mode of operation. You can also calculate the performance level yourself.
A power of 1 kW is on average 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;
- the condition of the ventilation system;
- heat leaks (frequency of opening gates or doors);
- the number of windows and doorways, their size;
- outdoor air temperature;
- condition of 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 the number, 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 place of installation also influences the efficiency of a diesel heater.
Useful advice! In large rooms, it is advisable to use several heaters. Placing fixtures 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 heating equipment is another parameter that you should pay attention to. The Ballu BHDN-20 indirect heating diesel cannon has this figure of 500 m³ / h. This means that the device is able to effectively heat the specified volume of air within 1 hour.
Not the 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 fired guns are the simplest devices that can serve as heat sources. Such designs have an open combustion chamber. A pump is installed inside, equipped with a nozzle, due to which a torch effect is provided. A fan is located behind these elements. All the heat that is generated in the process of fuel processing is supplied to the room along with the products of its combustion.
The principle of operation of a direct heating diesel cannon:
- Diesel fuel from the tank is fed into the heating filter.
- The compressor transports the fuel to the injector.
- Diesel fuel is ignited by the glow plug.
- A fan mounted behind the burner draws cold air from the room into the combustion chamber, where it is heated.
- A protective mesh at the front of the appliance traps the flame, preventing it from penetrating outside the combustion chamber housing.
- After heating, the air is fed back into the room.
Design and principle of operation. Varieties of thermal curtains. Installation and repair of the device. Well-known manufacturers.
The principle of operation of a direct heating gun is quite simple. It's efficient and straightforward. However, such guns have one significant drawback. All combustion products enter the premises, therefore 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 for diesel guns for space heating (direct heating structures):
|Brand name||Model||Power level, kW||price, rub.|
|Master||B 35 CEL DIY||10||21590|
|B 35 CED||10||21790|
|B 70 CED||20||31260|
Note!The use of fuel with impurities will lead to contamination of the injectors and other unpleasant consequences. Therefore, it is very important to use quality raw materials in order to avoid costly repairs and purchase of spare parts for the diesel cannon.
Consumer opinion 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, therefore, when the need to purchase a heater appeared, I didn’t think for a long time and made a bet on this manufacturer. The gun works great 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.

Features of diesel heat guns of indirect heating for a garage, prices and reviews
This type of cannon functions in much the same way as direct fired designs. The only difference is that the combustion products, which are formed in the process of fuel processing, 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 sufficient ventilation.
A nozzle is installed in the construction of a closed combustion chamber. In addition, the cannon 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 of indirect heating diesel guns:
|Brand name||Model||Power level, kW||price, rub.|
Useful advice!You can determine the thermal power of the 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 the 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 the one that is required to create a comfortable indoor microclimate.
Consumer Opinion About Diesel Heat Guns: Reviews of Indirect Heating Designs
Feedback from the 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 the maximum operating mode. It was the economy that attracted me to this model. The tank is designed for 30 liters. In winter I only use winter diesel, otherwise the fuel just settles. There are no problems with the launch. "
Evgeny Doroshenko, St. Petersburg
“After an accident on the heating main, which provided heating in the garage, I had to buy a Master BV77E diesel heat gun. The unit is, of course, dimensional. The hull length exceeds 1 m, and the weight of the structure with an empty tank is neither more nor less than 55 kg. Fortunately, the manufacturer has provided an opportunity for convenient transportation, which I could not help but appreciate. A trolley on wheels is included with the device. The construction is pretty solid. After 3 months, no breakdowns, backlash and extraneous sounds. The only thing I don't like is the need to constantly check the fuel. And the filters need to be changed from time to time. The rest of the device is great. "
Konstantin Nalivaiko, St. Petersburg
Features of the repair of diesel guns for heating premises
Maintenance of a diesel-fueled plant can be costly. Only one diagnostic procedure costs about 1000 rubles. For this reason, many owners of garages and storage facilities resort to self-repair of structures.
How to repair a diesel heat gun yourself
If warm air does not move, the fan motor may be defective. 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 adjustment is indispensable. In such cases, one thing remains - replacing the engine.
The nozzles are an important design detail.It depends on the quality of the work of these elements to the full functioning of the entire heating system. These parts rarely break, and new items to replace those that have failed can be bought at any store.
More often, the need to repair a diesel gun arises due to a clogged filter. To eliminate this breakdown, it is enough to open the body of the structure, unscrew the plug and get the contaminated element. After flushing with pure kerosene, the filter is ready for further use. Before installing this part in place, it is advisable to blow it out with a jet of compressed air.
Rules for the safe operation of diesel devices
When operating diesel appliances, it is very important to adhere to 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. The 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;
- pain and discomfort in the nose and throat, as well as in the eye area;
- headache that comes on suddenly;
The presence of carbon monoxide in a closed room negatively affects the condition of people suffering from diseases of the cardiovascular system and lungs. The presence of pregnant women and patients with anemia in the room where the gun works is not allowed.
Due to their economy, diesel cannons are so in demand on the market. Observing the basic rules of operation, you can avoid health problems. Otherwise, using a diesel cannon is safe. A high-quality device with suitable technical characteristics can provide a garage or warehouse with efficient 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.
