Diesel heat guns: types, characteristics, operating principles, reviews

As soon as the cold weather sets in, owners of apartments and houses begin to solve the heating problem. This also applies to those who have construction sites, production facilities, hangars, warehouses and garages. Non-residential buildings also need warmth and comfort. One heating method that is increasingly attracting consumers is the use of a diesel heat gun.

Before purchasing such equipment, you should familiarize yourself with its main types, understand the principle of operation and understand the characteristics. It wouldn't hurt to read the reviews as well.

Main types by heating type

The main purpose of heat guns is to economically and quickly heat large areas. Such equipment operates on diesel fuel, the combustion of which generates heat. It is distributed throughout the object by air flow. According to the design principle, heating guns can be divided into direct and indirect heating devices.

How does a diesel heat gun work?

The device has this name because of the shape of the body - a cylindrical shape, reminiscent of a cannon barrel.

Simplicity, mobility and practicality are the positive characteristics. Its structure is as follows:

• Cylinder-shaped metal body;
• Elements that heat the air entering inside;
• Parts that direct air flow into the housing.

The structure of a heat gun

The holes in the housing serve for the entry of air masses. With the help of a fan, the heated air rises upward into the room. Of the heating elements, burners or heaters are mainly used. Their work depends on fuel such as kerosene, refining, gasoline, diesel fuel, gas or any other.

The operating principle of direct heating guns and their design

The main element of a diesel gun is an electric motor with a fan. The design provides for:

• combustion chambers;
• pump with cleaning filters;
• spark generator;
• fuel tank;
• injectors.

As for the spark generator, it is a high-voltage system or a glow plug. In order to ensure autonomous operation of a diesel heat gun, it is equipped with a timer, thermostat and flame level control. This list of add-ons is not complete. The device may also include other electronic elements. They are built-in or installed additionally.

This unit works according to the following principle. When the equipment is turned on, fuel is pumped into the fuel filter, where it comes from the tank. A pump is involved in this process. At the next stage, the fuel ends up at the nozzle, which injects it into the combustion chamber. The spark is supplied by the ignition system, which helps ignite the diesel engine.

In the barrel of the device there is a protective mesh that holds the fire, because otherwise it could escape the combustion chamber. Cold air is forced into the chamber by a fan, where the flows are heated by fuel and come out as a warm flow.

The direct heating diesel heat gun has a high efficiency that reaches 100%. In this case, the outlet air temperature can reach 400 °C. Such heat generators have powers ranging from 10 to 220 kW. Due to the fact that along with heat, unpleasant odors and soot, as well as combustion products, appear in the air, the scope of use of the described unit is limited.

If the equipment does not have a chimney, then it can be used in monolithic production premises, warehouses and open areas. Such guns are widely used in construction, where they are used for drying concrete screeds and facades when applying plaster and for facing work.

Advantages and disadvantages

Diesel heat gun AURORA DIESEL HEAT 50

Diesel heat guns are widely popular. This is due to the many positive aspects highlighted during the operation of these heating units. Let's note the main advantages:

1. Small in size.
2. Easy to use and maintain, in order to start the device mechanism, just press a button.
3. The devices are highly economical. The amount of fuel consumed depends on the power of the heat gun. For example, with an air flow of 550 m³/hour, approximately 1.5 liters of fuel are consumed, and the power will be 20 kW. This amount of fuel will be enough to heat the garage.
4. Capable of heating a room in the shortest possible time.
5. They are safe to use. If the gun is installed in a room with good ventilation, then there will be no negative consequences in the form of a burning smell. It is also worth noting that if you touch the device while it is operating, there is no risk of burns, since the body heats up to a temperature of 30-35°C.
6. Another important feature of a heat gun is that it can work for a long time without refueling.

Despite the considerable number of advantages of heat guns, such devices also have disadvantages:

1. The operation of the devices is accompanied by noise.
2. Heat guns are energy dependent; the device cannot function without electrical energy.
3. If the appliance is operated continuously for a long time, you may smell diesel fuel.
4. Since diesel heaters are mainly intended for heating industrial premises, the cost of such devices is high.

Reviews of guns with indirect heating

If you are interested in a diesel indirect heat gun, then you should read reviews about it before purchasing it. From them you can understand that the design provides a closed combustion chamber and chimney. With the help of the latter, exhausts and spent fuel escape outside the premises.

The maximum power of such devices is only 85 kW, but quite complex modular units with several muzzles can also be found on sale. They reach up to 220 kW. According to users, the efficiency of such devices is less and is approximately 60%, but such units are suitable for heating greenhouses, livestock farms, exhibition pavilions, non-residential buildings, as well as industrial facilities. In all these conditions, people or animals may be present for a long time. This factor, according to consumers, is quite important when choosing a heat gun.

How to choose a heat gun

There are a few important things to consider before choosing a heat gun.

1. Unit form. Thermal liquid fuel heaters can have a rectangular or cylindrical shape. Due to the large area of ​​air flow distribution, rectangular ones can be used as the best option during indoor construction work.

   For spot heating of objects or areas in a room, a cylindrical gun is more suitable.

2. Mobility. Portable units are very convenient to use, they are easy to carry, some models are equipped with trolleys. Stationary units are used for constant heating of areas. When installing them, special installation work is required.

   Stationary type gun

3. Heating method. The air flow can be heated directly or indirectly. This is important if the heater will be used in rooms with people or animals.
4. Types of fuel used. The combustible mixture should be selected based on specific situations and the rationality of its use.
5. Noisy. Some heat guns (high power) using diesel fuel are not recommended for use in small rooms due to the noise they make.
6. Unit power. This parameter should be taken into account first of all before choosing a diesel heat gun. The quality of heating the room or drying it depends on it. Information about the power of the device can be found in its description.

Most heat guns have a temperature control knob that allows you to adjust the operation of the unit to a set room temperature, after which it turns off. The device does not turn on if the temperature on the display is set lower than in the room. Diesel heaters are also equipped with a protection system against overheating.

Distinctive features and selection criteria for diesel heat guns

It is necessary to maintain heat in those places where you have to work constantly - various workshops, warehouses, hangars, garages. One of the best options for maintaining the temperature in a room is a diesel heat gun. It has gained popularity for its low price and portability.

What are diesel heat guns?

The purpose of a heat gun is to heat a room. The design of the device is simple: the heat generator consists of a cylinder with a special built-in fan, a pump, a nozzle and a burner. At the bottom of the generator there is a fuel tank. The air is heated by the combustion of liquid fuel located in the tank.

Why is it needed and where is it used?

This device is needed to heat rooms in which people are usually busy with industrial activities. A diesel gun is easier to use and safer than a heating boiler, but it can still heat only a small part of the room.

Places where the diesel heat gun is used:

• in the garage, where direct heating of the air during the cold season is very necessary;
• when working with suspended ceilings, a heat gun also plays an important role;
• at a construction site, when you need to heat up building material left outside on a frosty day, a diesel gun may be needed; you just need to fill the tank with fuel and direct a stream of warm air in the right direction;
• can be used in agriculture, as well as for heating greenhouses and farms.

How it works: device and principle of operation

A diesel heat gun works on the following principle:

• from the tank, using a pump, the fuel goes to the nozzle;
• the combustible mixture begins to spread from the nozzle, since at this stage the pressure acting on the liquid rises;
• after which the resulting substance ignites in a chamber intended for this purpose;
• then the fan comes into operation, pumping air through the cylinder;
• At the outlet, the air stream is already very hot, this is the final stage.

Reviews of diesel heat guns: pros and cons

According to reviews from numerous network users, the advantages of a diesel heat gun are:

• quick heating of the room, while fuel consumption is kept to a minimum;
• beautiful case design, build quality;
• high heating power, due to which the rate of exit of thermal air increases;
• can be used in various situations, both indoors and outdoors;
• compact and convenient appearance;
• Multifunctionality and ease of operation have won a warm response from people who use this heater.

However, even a device endowed with so many advantages has its drawbacks. Below is a list of disadvantages of a diesel gun:

• a relatively small tank that holds a little fuel, which reduces the operating time of the device;
• slight odors that may be present when the diesel gun begins to operate;
• It is better to keep it warm, since in the cold it may not start immediately;
• sometimes during startup of the device, the exhaust may go indoors;
• there is noise during operation.

Direct or indirect heating: which is better?

Diesel heat guns can be of two types:

1. Direct heating gun.
2. Indirect heating gun.

Let's consider each type of this device separately.

The direct heating heat generator does not have a built-in chimney, but its design is simpler. Such guns are famous for their compactness, low cost, reliability, and are also easy to use. The fuel is ignited in them using a spark plug, or in some models from an electric spark gap. The heated air, along with the exhaust gases, enters the room where the gun is located.

This heater is recommended to be used only in non-residential premises with good ventilation or on open construction sites.

An indirectly heated diesel gun is used more often, since the exhaust gases are discharged outside without causing harm to others. The advantage of an indirect heating gun over a direct heating gun is the presence of a chimney and combustion chamber. The principle of operation is very simple: due to pressure, fuel enters the nozzle, then into the chamber where it is sprayed and ignited. The fan fills the device with air. The output is already heated air, the exhaust gases exit through the chimney without lingering in the room.

This gun is used in places where people may be. But it is still recommended to ventilate the room, since when the unit operates, the oxygen in the room burns out.

Before you buy a diesel gun, you need to decide for what purposes it will serve. At a construction site, a direct heating gun is more suitable, and for heating rooms with people, an indirect heating gun is more suitable.

Calculation of the minimum required power

The power of a diesel heat gun can be calculated using the following formula:

V * T * K = kcal/h: 1kW, where

V is the volume of the room, T is the difference between the temperature outside and inside the room, K is the thermal dissipation coefficient.

Example:

• V = 140 m3;
• T = 30°;
• K = 2;
• 140 * 30 * 2 = 8400 kcal/h
• 8400: 870 = 9.6 kW

So, we learned that to warm a room with an area of ​​140 m3, you need a gun with a minimum power of 9.6 kW.

Reviews about the model

The diesel heat gun described above, according to consumers, has many advantages, among which mobility should be highlighted. It is equipped with durable wheels that allow you to move the equipment around the territory. Buyers also like the low-temperature casing, which ensures safety.

You don’t have to worry about the flame cutting out during operation, since the manufacturer has provided additional protection. Electricity is consumed in a minimal amount. The case has a double-sided anti-corrosion coating. This, according to consumers, is quite often a decisive factor when choosing such equipment.

If you are interested in this direct heating diesel heat gun, then you should also pay attention to the presence of an air purification filter. The design includes a coarse fuel filter. You don’t have to monitor the fuel level; the built-in sensor will take care of this, making the device easier to operate. The fuel tank has an increased volume, which makes the operating time more impressive.

Operating principle

A heat gun running on diesel fuel is a heating device, the main function of which is to heat both residential buildings and premises such as production workshops, warehouses, hangars, garages, greenhouses, etc. in the shortest possible time.

The operating principle of such a heat gun is simple. It is based on the combustion of diesel fuel, and the heat generated as a result of this process is directed into the room by a powerful air flow. The fan is responsible for pumping warm air masses into the space.

The design of the device includes a tank into which fuel is poured. There is also a filter through which the mixture passes before entering the container, from where it is pumped for further use.

A distinctive feature of a heat gun is that such equipment is energy-dependent.

For normal operation of units with low power ratings, a voltage of 12 W or 24 W is sufficient. But still, most of the models produced need to be connected to a 220 W network. Electrical energy is necessary for the operation of the burner and for pumping heated air masses into heated rooms (it drives the fan).

The operating principle of the burner of any diesel fuel heat gun is as follows: it sprays diesel fuel and at the same time provides air supply. As a result, a mixture of fuel and air is formed, which ignites and creates a hot flame. The end result is the generation of heat, which, as already noted, is supplied to the room by means of a fan.

Characteristics of the Ballu-Biemmedue EC 32 indirect heating diesel gun

If you want to choose an indirectly heated diesel heat gun, you can pay attention to the above-mentioned model. Its cost is 83,400 rubles. The equipment is a mobile heat generator with an economical and powerful device for additional heating of ventilated rooms. This indicates that you can use the device in warehouses and industrial buildings.

The heat generator can be used for temporary camps, heating tents and sports facilities. This indirectly heated diesel heat gun has a tank for diesel fuel, a pipe for exhaust gases, and a combustion chamber made of stainless steel. To supply fuel, the manufacturer has provided a pumping system. The unit is mobile, because it is equipped with a handle and wheels.

Manufacturers

Today, diesel heat guns are quite popular and users note the high performance of such devices. The market offers a wide variety of different models of units produced by both Russian and foreign manufacturers.

Let's look at the most popular models of diesel heat guns.

You can also pay attention to the heat gun during testing.

To summarize, it is worth noting that a heat gun operating on diesel fuel is an effective and popular source of heat for premises, primarily for industrial purposes.

User reviews

Before making your final choice, experts recommend reading reviews from real consumers. If you are considering the model described above, then when you read the opinions of customers, you will be able to find out that the device has a control unit with a self-diagnosis function.

The design assumes the presence of a three-pass heat exchanger. The fuel tank is made of low-density polyethylene. Fuel is supplied by a pump system. The combustion chamber is cooled by an automatic system, which is certainly a plus, according to users.

The set includes a trolley with wheels. Reading reviews about a diesel heat gun, you can find out that it has a drain for low-quality fuel. As for the fuel hoses, they have a textile braid. Buyers consider this feature an undeniable advantage.

Start-up and safe operation rules

Typically, devices are supplied partially disassembled. That is, you will need to fix the “barrel” of the gun on a wheeled cart and install a handle (or metal arches). If we are talking about a direct heating gun, then all that remains is to fill the fuel tank, connect the device to the power supply, set the heating temperature and press the power switch.

Thanks to the built-in thermostat, the gun will automatically stop working when the air warms up and turn on again when the temperature drops - this way the device saves fuel and eliminates the possibility of overheating

To start up the equipment, make sure that the following safety rules are observed:

1. The gun is installed on a stable and level horizontal surface made of non-combustible materials, such as concrete. If the floor is wooden, you can place sheet metal under the unit.
2. The distance from the nozzle from which the hot air flow will flow to the nearest object is at least 2 meters (it is advisable to maintain a distance of 80-100 cm on the right and left).
3. Before the first start-up or after long-term storage, it is recommended to open the housing and manually turn the fan impeller to make sure that it rotates freely.
4. The device will “signal” the need for refueling by intermittent combustion or the release of white smoke. To add fuel, be sure to disconnect the gun from the power supply.
5. Always turn off the gun with the toggle switch and wait until the fan stops completely. For indirect heating devices, this process may take 2-5 minutes, but it is necessary to cool the combustion chamber. Only after this can you unplug the device from the network.

To start an indirect heating diesel gun, you must first install a chimney - a round pipe made of non-combustible material with a maximum length of 3 meters. If you need output over a long distance, it is convenient to use flexible aluminum corrugation for this purpose, but it will have to be changed several times during the heating season.

To remove it into a nearby ventilation, you can find a piece of steel pipe that will last much longer.

The chimney path for an indirect heating gun must be laid in a straight line, with a maximum of only one bend of up to 90 degrees allowed.

As for maintenance, for trouble-free operation of diesel heat generators, you will need to periodically wash the air filters and clean the combustion chamber of soot/dust. It is also important to keep the internal walls of the unit clean in the area of ​​the injector and engine.

Characteristics of the heat gun brand "Parma TPD-52 N 02.011.00039"

You can purchase this equipment for 59,800 rubles. It is a device with efficient and fast heating of large and medium-sized rooms. The model has a pipe for removing combustion products, which allows the gun to be used in places where people are present.

Looking at the design of a diesel heat gun in more detail, you will be able to understand that it has a built-in stabilizer and electronically controlled ignition. Air during operation is consumed in a volume of 1800 cubic meters per hour. The heating method is indirect. The equipment weighs 55.4 kg.

The tank holds 55.5 liters of fuel. When heating, the power is 52 kW. The included outlet pipe has a diameter of 1200 mm. When considering the characteristics of a diesel heat gun, you should also pay attention to fuel consumption, which in this case is 4.3 liters per hour.

How is the power of a heat gun calculated?

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

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

For different types of premises the coefficient values ​​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 an average level of thermal insulation (2 bricks and several windows, standard roof);
• from 0.6 to 0.9 – a building with high quality thermal insulation. Brick structure with double insulation. Double glazed windows. The base under the floor is of sufficient thickness. High quality material was used on the roof for insulation.

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

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

We substitute the data into the formula: 150 * 29 * 2 = 8700 kcal/h, despite the fact that 1 kWh = 860 kcal/h. This means: 8700 / 860 = 10.116 kWh. Thus, we learned that to warm up 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.

Reviews

Before making a choice, you should pay attention to consumer reviews. In the case of the described model, the presence of controlled electronic ignition should be taken into account. At reduced voltage, operation is possible, as well as during voltage surges. This feature is considered a plus by consumers.

You may also be interested in the flame control system. The unit can be used to heat rooms and small structures, as well as in a small area, their internal space. Having considered the operating principle of a diesel heat gun, you should have understood that the efficiency is extremely important during operation. In this case it reaches 82%.

Direct heating heat generator

A direct heating diesel heat gun is not equipped with a chimney and has the simplest design. Therefore, direct-flow heaters are inexpensive, compact, easy to use and reliable. Ignition of the fuel occurs using a spark plug, in some models - from an electric spark gap. The heated stream of air, along with the exhaust gases, enters the building that needs to be warmed up.

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

Below is shown the design of a diesel installation using the direct heating method.

Comparison with a gas gun

Before comparing gas and diesel guns, you should dwell in a little more detail on the features of the first. The design of gas guns is in many ways similar to diesel equipment, but there are some differences. Namely, during the combustion of gas, almost no hazardous substances are released, and there is no chimney to remove them. Like diesel guns, gas equipment has an efficiency of 100%, so they can work effectively in any warehouse, production and construction premises. The only drawback of gas guns, if it can be considered such, is the need to always have a spare gas cylinder readily available .

However, do not forget that gas is much more dangerous than any diesel fuel. However, if you follow all safety rules, you should not be afraid of an explosion.

It is almost impossible to give an objective answer to the question of which gun is better: gas or diesel. In any case, you need to consider your own needs, usage patterns, as well as the budget you can manage. For example, for continuous heating of a fairly spacious room in which there are people or some animals, and also has its own gas pipeline, a gas heat gun would be the optimal solution. For temporary work, for example, repairs or construction, as well as in hangars and workshops, a diesel model on wheels would be the best choice.

Its increased power, the ability to move from one room to another, as well as the high quality of drying materials, combined with the availability of fuel, make such a unit a very successful and profitable purchase.

Design and principle of operation

The operating principle of these structures is quite simple: diesel combustion occurs inside each, heat is generated, and with the help of a powerful fan it is supplied outside. Diesel is usually used as fuel. The internal device has a progressive design, due to which the efficiency of the equipment reaches 100% . The design is not autonomous, but dependent on the power supply of a standard 220 volt network. The heat gun needs electricity to activate the burner. In addition, without it it is impossible to transmit.

The burner has the ability not only to atomize fuel, it also promotes efficient air supply. As a result, flammable mixtures are formed and the flame remains stable and steady.

Features of repair of diesel guns for space heating

Repair maintenance for a diesel fuel-powered installation can cost a significant amount. Just 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 warm air does not move, the fan motor may be faulty. Repair involves cleaning the terminals, checking the winding on the motor (an analog tester is suitable for this), as well as insulation. Sometimes the damage is so serious that superficial adjustments are not enough. In such cases, there is only one thing left - replacing the engine.

An important design detail is the nozzles. The quality of operation of these elements depends on the full functioning of the entire heating system. These parts rarely break, and new elements to replace failed ones can be bought at any store.

Modern diesel, gas and electric heat guns are equipped with a convenient control panel that allows you to adjust the air heating temperature

Much more often, the need to repair a diesel gun arises due to a clogged filter. To eliminate this breakdown, simply open the housing of the structure, unscrew the plug and remove the contaminated element. After washing with clean 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 appliances

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 likelihood 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 the eye area;
• headache that appeared suddenly;
• nausea.
