Heat guns on diesel fuel: repair recommendations and reviews. How do heat guns work on diesel fuel, and how does direct heating differ from indirect heating?

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 heat gun on solarium.

An important advantage of a diesel unit for maintaining heat is high performance and long service life without additional refueling. In principle, these are the same fan heaters, and the device has a heating element that is reliably protected from external influences.

How do solar heat guns work?

The interior quickly reaches the desired temperature if it functions 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 not direct heating, then it is preferable to use it in , since in similar units a special pipe is provided 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, various types of 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.

Residents of private houses are wondering how to create economical heating private house? AT winter time buildings cool down quickly and need a heating system. Today there are many...

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 a diesel heat gun indirect heating with suitable specifications.

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 heat guns diesel fuel 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 capable of generating a large number of heat, thereby expanding the scope of its application.

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 light in weight, while they have 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.

Often mentioned high level noise 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 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 of the 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.

Useful advice! In large rooms, it is desirable 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. For an indirect heating diesel gun 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.

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 for the ability to adjust the pressure on the compressor that the diesel supplies. There is only one downside - full tank The device is a bit heavy.

Igor Samoilov, Moscow

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 design 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:

Useful 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 outdoor temperature and that required to create a comfortable indoor microclimate.

As a rule, with the onset of the cold period of the year, the problem of heating premises for various purposes sharply arises.

And this applies to both private residential buildings, and industrial premises different type. In such cases, the heat supply from the central heating system is expected. But what about when central heating still not working or not at all in the room?

In such situations, one usually tries to use alternative sources heating, which can safely be attributed to such a type of units as heat guns.

Modern market heating equipment has enough a wide range of heat guns various kinds. But special place this range is occupied by diesel.

To have an idea about this type of thermal units, in this article we will talk about what diesel heat guns are, what characteristics they have, and also where they can be used.

What are

A diesel heat gun is a kind of heating unit, the main purpose of which is to quickly and economical heating such non-residential premises as production workshops, agricultural storage facilities, construction sites And so on.

A distinctive feature of this type of heat guns is that the thermal air flow is formed as a result of the combustion of liquid diesel fuel.

Advantages of application

The use of diesel heat guns for household purposes carries a number of positive and indisputable points, which are undoubtedly associated with the following advantages of this type of unit:

• excellent performance characteristics;
• simple maintenance;
• depending on the type, the power of diesel heat guns varies from 20 to 230 kW;
• enough economical consumption diesel fuel;
• opportunity to work in offline more than 10 hours;
• good functioning of the unit at low temperatures;
• perfectly heat large areas.

Based on the positive aspects of the diesel heat gun, we can safely say that it is effective device for space heating.

Kinds

Diesel heat guns are usually divided into two main options:

• direct heating units;
• indirect heating units.

Consider the principle of operation of each of these types of heat guns.

direct heating

The principle of operation of a diesel heat gun is as follows:

As you can see, the principle of operation of a diesel heat gun with direct heating is quite effective and understandable.

But the unit of this type has one significant drawback: together with the air heat flow, the combustion products of diesel fuel also enter the room.

In this regard, the following requirements are imposed on the use of diesel heat guns:

• the use of this type of unit in residential buildings is prohibited;
• the room where the heat gun works must be equipped with a good ventilation system;
• with the help of this type of unit, it is allowed to perform all work operations, without exception, in open areas.

indirect heating

The principle of operation of a heat gun with indirect heating is almost the same as the previous type.

However, this type of unit has a significant advantage: the exhaust products of combustion are removed outside the premises through a specially equipped chimney. Thus, heat guns with indirect heating can be effectively used in residential areas, provided there is proper ventilation.

Converting direct heating to indirect

In order to understand this issue, you need to turn again to the design of these types of heat guns.

If in units with direct heating, the combustion products come out with warm air, then this means that the combustion chamber is of an open type.

In a heat gun with indirect heating, emissions are removed using a nozzle, so the combustion chamber is presented as a closed heat exchanger. Consequently, the process of converting a direct heating heat gun into an indirect one consists in replacing the combustion chamber, as well as equipping the unit with an outlet pipe.

But here the obvious question arises about the effectiveness and cost of such a method of technical alteration of the heat gun, which remains open.

The lineup

Despite the fact that heat guns are rather narrow-profile equipment, nevertheless, on modern market these units are represented by many manufacturers.

After analyzing the products of manufacturers of heat guns, we have identified a number of the following most popular models:

Thus, we introduced you to all the characteristics of diesel heat guns, indicated the features of different types, and also provided a list of the most popular heat guns. We hope that the above information will greatly help you when choosing a heat gun.

Watch a video in which a specialist talks about the device and types of diesel heat guns:

In the conditions of our cold winter we can not do without space heating. Often needs to be warmed up separate sections premises or create conditions for working outdoors in frost. Solving the problem of heating buildings under construction, garages, warehouses will help the use of special equipment for heating high power - heat guns. One of the advantages of these powerful fan heaters is their high mobility, they can be easily transported to the right place.

Principle of operation

The heat gun is a powerful air heater. Works just like a regular household heater. Heating element, located in the gun body, heats up itself and heats the air flow passing through it. The output is a very powerful jet warm air. Hence the name of the unit - a heat gun.

At the same time, the process of heat transfer occurs almost instantly, which allows you to heat the air in the room very quickly.

Manufacturers produce models that run on different types fuel. On the market are:

• diesel fueled units
• on kerosene
• on liquefied gas
• electric heat guns.

Diesel heat guns of direct heating are often used in construction. For example, with a device stretch ceilings mobile heat gun is indispensable. Heat guns can be used when you need to quickly dry the surface

Diesel heat guns

Diesel heat guns are the most popular. This is primarily due to the availability of the fuel used - diesel fuel. Naturally, when diesel fuel is burned, combustion products are released.

With this in mind, there are two main types of diesel fuel heat guns on the market. They differ from each other in the way the exhaust gases are removed:

• diesel guns of direct heating, in which the heated air is discharged directly into the room
• guns of indirect heating. The design of the unit provides for the removal of exhaust gases outside the premises.

The price of the unit directly depends on the design of the heat gun, in other words, on the method of heating the air flow. If it's about diesel guns, then direct-heated guns are about half the price. This design has its pros and cons.

Heat guns of direct heating

The principle of operation of a direct heating diesel heat gun is simple. A powerful fan with an electric motor is located in the unit case. From the fuel tank, fuel is pumped into the combustion chamber by means of a pump. Since the burner is inside the housing, open fire while not. In view of this, heat guns can be used indoors.

When burned, diesel fuel heats the air flow coming from the fan. The heated air flow passes through a special screen and is directed to the object that you want to heat. At the same time, waste products of combustion, the same exhaust gases, dust, soot are discharged together with the air flow into the heated zone.

Therefore, direct heating diesel heat guns can be used in well-ventilated rooms, semi-open rooms or outdoors.

Most often, such units are used if necessary to perform one-time work. For example, in winter, a car engine froze in frost, warmed it up with a cannon, repaired it and drove off. Or in construction industry to speed up the process. The builders completed, for example, a screed, and warmed up the room with a heat gun for fast drying. It is important that people do not stay indoors for a long time during the operation of the unit, so as not to be poisoned by combustion products.

If you are faced with the task of heating a room in which people stay for a long time, you should choose an indirect heat gun.

Heat guns of indirect heating

The device of a diesel heat gun of indirect heating is a little more complicated. In such designs, a special chamber is added - a heat exchanger. Fuel is supplied from the fuel tank to the combustion chamber, while the combustion products of diesel fuel do not mix with the air flow from the fan, but are discharged through the chimney to the outside. The task of the user is only to organize the output chimney from indoors to outdoors.

During the operation of the gun, the heat exchanger heats up itself and heats the air that drives the fan. A heated, and at the same time free from combustion products, air stream comes out of the nozzle of the heat gun. Such units can give an outlet temperature of 50 to 110⁰С.

Heat guns of indirect heating can be used in rooms with working people without restrictions, exhaust gases will not enter the room.

combustion chamber in modern models Made from high strength stainless steel. To protect against overheating, the guns are equipped with thermostats that automatically reduce the intensity of the flame when overheated. The outer casing of the unit does not heat up at all.

By the way, an additional thermostat installed in the room can be additionally connected to the device. In this case, the heat gun will be able to automatically maintain the set temperature in the room. And the unit itself can work up to 16 hours without stopping.

In order to warm up large area, the kit includes flexible hoses- corrugations made of durable material with a diameter of 300-600 mm. With the help of corrugations, you can direct the warm air flow to the right place for organizing local heating.

With the help of heat guns of indirect heating, you can easily solve the problem of heating shops, stalls, warehouses, car washes and exhibition centers.

Infrared diesel heat gun

There is another type of guns that run on diesel fuel. These are infrared heat guns. The design of these units does not include a fan heater. These heaters work on a different principle.

Infrared heaters do not heat the air masses in the room, like the fan heaters we are used to, but objects that fall into the field of infrared radiation. In turn, objects heat the air through heat exchange.

In design infrared gun using a burner with diesel fuel is heated infrared emitter. He, in turn, heats objects and surfaces in the room, it remains only to direct in the right direction.

The absence of a fan can be attributed to positive moment of this unit. After all, fans work, making noise, and infrared heat guns are almost silent.

How to calculate the power of a heat gun

As you can see, the scope of a diesel heat gun directly depends on the principle of operation. to someone suitable option with direct heating, but for some, these models will be unacceptable.

There is another factor influencing the choice of model is its power. AT different models it varies from 20 to 220 kW. In fact, if your task is to purchase an air heater for mounting stretch ceilings, it makes no sense for you to purchase a unit increased power, after all, his fuel consumption will be many times greater.

In order to determine the choice of model, you need to calculate the required power of the unit. To do this, you need to know the volume of the room. Recall that the volume is easy to calculate, knowing its dimensions - the length, width and height of the walls. In addition, you need to know the degree of thermal insulation of the room, it is indicated by the coefficient of thermal insulation.

The coefficient of thermal insulation is different for:

• uninsulated rooms from wooden structures or metal sheets(for example, a metal shell garage). K warm = 3.0-4.0
• uninsulated brick rooms with a single brickwork, single windows, non-insulated roof (for example, country house). K warm = 2.0-2.9
• standard brick buildings with conventional thermal insulation, such as a standard residential building. K warm = 1.0-1.9
• buildings with improved thermal insulation. K heat = 0.6-0.9

To calculate the power, you need to know the temperature difference between the outside and inside the room.

The power of the unit is calculated as follows: the volume of the room is multiplied by the temperature difference and multiplied by the thermal insulation coefficient.

For an uninsulated warehouse, we take the thermal insulation coefficient equal to 2. Well, suppose that the temperature outside the window is -5⁰С, and we need +16⁰С (the minimum allowable at the workplace). The temperature difference turned out to be 21⁰.

We calculate the required power. 300*21*2=12600 kcal/hour. To convert to the usual kW, divide the value by 860. We get

12600 /860=14.7 kW.

This means that to maintain the temperature in our warehouse at 16⁰, we need a heat gun with a capacity of at least 15 kW.

Diesel heat guns will good decision heating problems of any premises. Mobility and ease of operation, as well as the possibility of choosing a design depending on the purpose, make this heating equipment unrivaled. We hope our material will help you in choosing the right unit for you.
