Diesel thermal gun: device, pros and cons, opportunities. Solar heat guns. Heat gun: instructions, price and reviews How the power of the heat gun is calculated

If you need to heat a workshop (workshop, garage, change house, hangar), or you cannot continue repairs in winter due to low temperatures and high humidity in the building, or your car when severe frosts does not start, then thermal diesel guns will become an indispensable thing in this matter.

Essentially, a heat gun is heat generator for space heating. In it, the air flow is heated by the combustion of liquid fuel. It consists of a cylinder with a built-in fan, pump, nozzle and burner. At the very bottom is the fuel tank. The principle of operation of a diesel heat gun is simple:

• from the tank, with the help of a pump, fuel enters the nozzle;
• a combustible mixture begins to spread from the nozzle under pressure;
• fuel ignites in the chamber;
• the fan pumps air through the cylinder;
• at the exit we get a jet of very heated air.

heat gun on the diesel fuel there are 2 types:

1. Heat generator direct heating.
2. Heat generator of indirect heating.

Direct heating heat generator

The diesel heat gun of direct heating is not equipped with a chimney and has the simplest design. Therefore, once-through heaters are inexpensive, compact, easy to use and reliable. The fuel is ignited using a spark plug, in some models - from electrical arrester. The heated air stream, together with the exhaust gases, enters the building that needs to be heated.

The use of such a heater is possible only in non-residential buildings with a good ventilation system or on construction sites (open).

Device shown below diesel plant direct method heating.

Indirect heat generator

A diesel heat gun of indirect heating is used in all cases, as a direct-flow one. But due to the fact that gases are vented to the outside, the range of its application is significantly expanded:

• in construction;
• agriculture;
• in production shops;
• for drying plaster (putty) in the cold season;
• concrete heating;
• drying facades during facing works;
• for heating trenches;
• heating of greenhouses, farms in animal husbandry;
• home heating, etc.

The design of diesel heat guns with exhaust gases contains closed cell, in which fuel burns, and a chimney. The fuel is supplied under pressure to the nozzle, in the chamber it is sprayed in the form of an aerosol and ignites. Air is blown into the unit by a fan. To maintain the combustion process through the holes located at the back, part of the air enters the chamber. The rest of the flow moves between the casing of the heater and the combustion chamber, where it is heated. The smoke leaves the chamber through the chimney and is discharged outside, bypassing the room.

The use of such diesel heat guns is allowed for heating garages, rooms with people in them, pavilions. But during the operation of the heater, oxygen burns out, so you need to ensure ventilation to compensate for his loss.

A liquid fuel heat gun can also be multi-fuel. This means that the unit is able to operate on waste oil, gasoline, diesel fuel, kerosene. Often this kind of heaters are used in places with a sufficient amount of oil products and their waste. It can be: fuel depots, car parks or car services. At the same time, the problem of fuel and lubricants waste disposal is solved and heating is obtained free.

The figure below shows the operation of a multi-fuel generator.

Diesel infrared guns

The liquid-fuel infrared heat gun heats large rooms with high efficiency and at the same time efficiency. It can also be successfully applied to outdoors. This type of heat generator heats the objects themselves, towards which it is directed. Air heating comes from objects heated by the rays, and the height of the ceilings in the room does not play a significant role. These features result in significant fuel savings.

Using this property, it is convenient to heat objects in the open air pointwise.

How to choose a heat gun

Before choosing a heat gun, there are a few important things to consider.

Most heat guns have a handle temperature control, with which you can adjust the operation of the unit to a predetermined temperature in the room, after which it turns off. The device does not turn on if the temperature on the display is lower than in the room. Also, diesel heaters are equipped with protective system from overheating.

How is heat gun power calculated?

The thermal power of the device is calculated by the formula: V * T * K = kcal / h, where:

• V is the volume of the room (width * length * height), in m3;
• T is the difference between the temperature outside and in the room, in degrees Celsius;
• K is the coefficient of thermal dissipation.

For different types premises, the values ​​of the coefficient are set:

• from 3.0 to 4.0 - a room in which thermal insulation is not provided, for example, a structure made of wood or sheet metal;
• from 2.0 to 2.9 - a room with poor thermal insulation. A simple building with one brick masonry;
• from 1.0 to 1.9 - a building with middle level thermal insulation (laying in 2 bricks and several windows, standard roof);
• from 0.6 to 0.9 - building with thermal insulation High Quality. brick building double insulated. Double glazing on windows. The base under the floor is of sufficient thickness. On the roof, for insulation, high quality material is used.

An example of calculating the power of a thermal diesel gun:

• V = 150 m3;
• T = 29°C ( outdoor temperature-10°С, required indoors +19°С, the difference will be - +29°С);
• K = 2 (one-brick building);

We substitute the data into the formula: 150 * 29 * 2 = 8700 kcal / h, despite the fact that 1 kWh = 860 kcal / h. So: 8700/860 = 10.116 kWh. Thus, we learned that to heat this building, a liquid fuel heat gun with a minimum power of 10 kWh is required. It is recommended to buy a unit with some power reserve.

Advantages of diesel heat generators

When using diesel heat guns, there are several positive points:

• excellent performance characteristics;
• ease of maintenance;
• power can reach up to 230 kW;
• very low fuel consumption;
• battery life more than 10 hours;
• works well at low temperatures;
• the ability to quickly heat large areas.

Based on the above positive points, it is safe to say that the heat gun is the most effective device for heating residential and industrial premises.

Maintaining heat inside the garage in winter becomes especially relevant if you need to mess with the car, so the heating system must be efficient and reliable. Solar heat guns do a good job with this job. They are sold in stores where you can buy tools, car parts, and much more of that kind. Diesel fuel heat guns are characterized by good performance, save the owner's money, and, if properly handled, do not pose any health hazard.

general characteristics

To understand the advantages of such equipment, you need to know what it is. Diesel heat gun works on simple principle, similar to that used in domestic fan heaters - the air is heated with its subsequent injection into the jet. When he finds himself in a cold surrounding space, hot streams give their energy to the masses of cold air. This cycle continues until there is a complete heating of all inner space to the optimum temperature.

Device

Diesel fuel heat guns are equipped with a reliable metal housing designed to protect the heating element and supercharger from damage or penetration of objects that can ignite and cause a fire.

The design necessarily includes a safety element that turns off the system in case of overheating. Therefore, solar heat guns can be safely turned on to warm up the room in which you are doing something, and at the same time do not worry much. However, no one canceled the observance of safety precautions.

Principle of operation

Diesel fuel heat guns, prices for which start at 3,500 rubles, consist of several basic elements: a fan that drives air through the heater, a heating element, as well as the case in which everything is placed. This description is quite general, but there is no need to understand the intricacies of the device of such equipment for those who use it. If a person's profession is the repair of heat guns, then this is another matter.

So, everything is clear with the device, and with the principle of operation, everything is not much more complicated here. Due to the combustion of fuel, the air is enriched with heat. It is driven by a fan through the heating zone. And how exactly the air is heated, and allows us to divide the guns into two categories.

Types of heat guns

Speaking about safety, many may think, but where do they go, because diesel fuel burns out and forms certain substances that need to be removed. All these compounds are quite dangerous for human health, so it is important to take care of their diversion. And then it's time to talk about the fact that there are two types of heat guns on diesel fuel: direct and indirect heating. Each of these species has its own character traits, features and possibilities for use.

Thermal indirect heating is well suited for the garage. This design assumes the presence of a branch pipe - it is designed to remove exhaust gases. A hose is attached to it, which can later be taken outside. This will not lead to any significant heat loss, however, harmful carbon monoxide, as well as other substances that are hazardous to health. That is why the diesel heat gun is perceived by many as the best option compared to gas models. Many gas-powered appliances do not have this method of venting combustion products, so you will need to open the garage for ventilation, which will cause significant loss of precious heat.

Direct heat gun

This option is not suitable for rooms in which there are people, since the products of combustion of diesel fuel are mixed with hot air and accumulate in the room. Therefore, the choice should be based on the most thorough study of information about the device. If you need a heat gun, the instructions for which indicate the impossibility of using it in a room where people are, then you should think about it before buying it.

Scope of application

Solar heat guns can be found in many places. They are usually used for heating, during installation stretch ceilings to speed up the film heating process, as well as wherever there is a need for mobile devices capable of quickly and not too expensively heating rooms of different sizes.

The most widespread heat guns, reviews of which are mostly positive from users, were received as devices for heating warehouses, construction halls, as well as other places where heating is required, but the use of traditional equipment is difficult or impossible for some reason . In particular, such devices become relevant for buildings in which there is no direct connection to electrical networks. The operation of a heat gun also requires a certain flow. electrical energy, but not so much is needed, so a small portable generator is quite capable of coping with such a task.

Special types

Heat guns on diesel fuel that use deserve special attention. This type of equipment heats the room without the use of a fan, while the air temperature does not rise due to its direct heating. Like all infrared-type heaters, such a gun heats planes and objects, and not the air masses inside the room. heating element here, as in all other cases, it works by burning fuel, but without involving a fan. This makes such a device completely silent during operation, which adds certain advantages to it.

Operating rules

The basic requirements for the use of equipment differ depending on which type of instrument is used. If we are talking about a gun with direct heating, then it is required high-quality ventilation heated zone. Most often, thermal units are used for local heating of rooms with good ventilation or semi-closed type. For heaters that use indirect heat transfer, there are no such stringent requirements, since a chimney can be used to remove combustion products.

Solar heat guns are increasingly used in the installation of stretch coatings in rooms. The operation of such units requires minimum flow fuel, which significantly reduces costs. In this case, the requirements for the organization of the operation of the device require the organization of the removal of exhaust gases, which, as mentioned above, is done very simply.

Advantages

The price of a heat gun can be from 3500 rubles (depending on the power and manufacturer), and its upper limit is not limited. Such heaters are able to work not only on diesel fuel, but also on kerosene or waste oil. Thanks to small additions to the design, such fuel can also be used, as a result of which the efficiency of the equipment increases several times.

The main advantage of such devices is their mobility. They weigh quite a bit, and their bulk is a fuel tank, the dimensions of which depend on the power of the device. Thanks to this, you can easily transport equipment and install it in different places.

Pretty big the lineup allows you to pick up suitable option to solve any problems. The maximum efficiency of the heat gun is ensured even with its minimum size, while maintenance costs can hardly be called significant.

This becomes quite relevant in those moments when you need to quickly and very strongly warm up the room in which repair work. In particular, when installing stretch ceilings. With the help of a gun, the air is heated to the required temperature. Due to the highest mobility of such a heater, it can be brought into the room without any difficulties, and then removed from there. For this, there is no need to attract additional personnel, everything is done by the masters who carry out the direct installation of the coating.

Repair of heat guns is also not particularly difficult. These tasks require minimum set tools and basic knowledge of oil-fired heating equipment.

Advantages

Safety is a significant factor when choosing a heating device. For this setting gas guns far behind diesel ones, and electric ones require access to the power supply network. Therefore, it is the diesel option that can be considered optimal.

Reliability is an important parameter, and it is he who tells what is better in favor of such equipment. A diesel heat gun of indirect heating is practically not subject to breakdowns, and its repair is much easier than in the case of using gas units.

All these factors speak in favor of the fact that this is a reliable, economical and convenient equipment. The only thing that can overshadow the use of such heaters is the requirement for a gas outlet pipe or ventilation.

Conclusion

It is already clear what qualities heat guns have. Reviews of such equipment speak of maximum convenience and ease of use. All those who have had to use it testify that it is modern way quickly and efficiently heat up any room. Such devices are in particular demand among the masters of the repair of premises, since a number of operations are performed with their help. The price of a heat gun is quite affordable, so such a device pays off very quickly.

The device of the unit includes a metal case, which is able to protect the structure from various damages. Heating parts are fireproof. All models are lightweight, which allows them to be moved anywhere.

Diesel structures are often in demand in the construction of various facilities. They are used when necessary to quickly dry the surface. Liquid-fueled designs are of indirect and direct heating. The first method is to withdraw flue gases from the premises. The operation of such devices is accompanied by the burnout of oxygen, so they are used outdoors or in rooms with flow ventilation.

How to choose a diesel heat gun?

Keep in mind that combustion products are expelled when starting a diesel-fuelled heat gun. Manufacturers offer two types of such devices: direct heating and indirect heating.

When choosing a design, the following factors are important:

• area of ​​the room;
• availability of fuel raw materials;
• the ability to withdraw harmful impurities, and ventilation;
• how it will be operated: permanently or periodically.

Diesel units contain a burner, combustion chambers, a fuel tank and a fan. Some products are equipped with wheels for ease of movement. Fuel is supplied by a pump.

Helpful information! When choosing a model, in the calculations, rely on the following indicators. For 10 sq. m. will need about 0.9-1.5 kW.

The nuances of choosing a direct heating diesel heat gun

The diesel fuel heat gun has a simple direct heating mechanism. Inside the product there is an electric motor and a fan. Using pumping unit fuel is delivered to the furnace tank. The burner is mounted inside the body, so there is no open flame.

When burned out, the diesel fuel warms up the air masses, which are removed from the fan. Heated air is distributed in space. And the smoke masses diverge into the inside of the building. Therefore, such devices can be used outdoors or in buildings with a good ventilation system.

Note! Such models are suitable for short-term work. For example, dry work surface at construction work or warm up a frozen engine.

How to choose an indirect diesel heat gun?

In indirect heating installations, in addition to the main elements, there is also a heat exchanger. The fuel moves from a special tank to the furnace tank. At the same time, the flue gases do not mix with the air masses from the fan, but exit through the chimney structure to the street.

When the device is turned on, the heat exchanger warms up and heats the air. At the outlet, such devices can emit from 50 to 110 degrees of heat. This technique is used in factories and warehouses, since harmful gases do not pass inside. AT modern equipment furnace tanks are made of stainless steel.

Some appliances are equipped flexible hoses, allowing to release a warm stream to a certain area.

Helpful information! A thermostat can be connected to the equipment, which is mounted inside the building. At the same time, the equipment will be able to maintain the required temperature and will produce heat for about 17 hours.

Models of infrared diesel heat guns

The installation of an infrared diesel heat gun does not include a fan heater. Such heaters do not heat the atmosphere, but the surrounding objects with the help of infrared radiation.

Burner with diesel feed warms up infrared emitter, which heats surfaces and objects in the room. silent, as their device does without a fan.

Model overview

To decide which heat gun is better gas or diesel, a review of the prices of individual models will help.

• Ballu's models are mainly used for large factories and warehouses. The equipment is known for functionality, good performance and pleasing design;
• in the arsenal of Kerona there are models of both economy class and luxury class. All models run on kerosene or diesel fuel.

How to calculate the power of the equipment?

An important factor influencing the preference for a particular product is power. This figure is in the range from 20 to 220 kW. To calculate the unit with what power you need, you need to calculate the volume of the room. For this, the height, width and length of the walls are determined. You should also know the quality of the thermal insulation. This coefficient will differ for non-insulated brick and wooden buildings, as well as in buildings with high thermal insulation. To carry out calculations, it is worth determining the difference in temperature values ​​​​inside and outside the building. In this case, the power of the device is calculated as follows, the volume of the room is multiplied by the temperature difference and the thermal insulation coefficient.

Models of heat guns on waste oil will be an excellent solution for heating any room.

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 keep warm 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 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 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 it is preferable to gas units, which do not always have enough safety equipment 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

Need to know how to change diesel gun direct heating, 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 desired 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.
