Electric heat gun: types, how to choose, an overview of the best manufacturers

Calculation example

The dimensions of the heated object are 10 square meters. m, and the level of its upper boundary is 3 m. Therefore, the volume of the object will be 30 cubic meters. m. Suppose that the device must heat the air in the room to at least + 15 ° C, while outside - frost -20 ° C. Therefore, the difference between these values ​​reaches 35°C. Let's say that the walls of the building are excellent at retaining heat, and the thermal conductivity multiplier will be 1 unit.

In this video you will learn the pros and cons of a heat gun:

The calculation of the required power is carried out as follows: 30 times 35 times 1, then divide the resulting number by 860.It turns out the amount of 1.22 kW. This means that for a room with an area of ​​​​10 square meters. m, a heat gun with a power of 1.22 kW will be optimal for the best heating in the winter. But at the same time, it is better to purchase a model with some reserve, for example, with a power of 1.5 kW.

If you systematize the heating equipment by power, then products up to 5 kW are considered as household ones. Such heat guns operate from an electrical network with a voltage of 220 V. They are very easy to use in summer cottages, car garages, offices, private cottages. Sometimes such units are called fan heaters.

No. 10. Popular manufacturers

It may seem that a heat gun is an extremely simple mechanism that cannot be made poorly. Drive away such thoughts. Both electric, gas and liquid fuel models are complex equipment, the quality of production of which depends on your safety, not to mention the heating efficiency.

Among the largest manufacturers of heat guns, we note:

Ballu is a world-famous manufacturer that produces electric, diesel and gas guns of various capacities and purposes (household and industrial). These are devices thought out to the smallest detail, the safety and effectiveness of which can be no doubt;
FUBAG - German equipment that runs on diesel and gas

The manufacturer pays attention to the little things, so the output is high-quality products in all respects;
Master - guns of the highest quality. There are products that can run on electricity, diesel, gas, waste oil, as well as infrared devices.
Timberk specializes in electric heat guns that are more economical than many other manufacturers;
Elitech - gas, electric and diesel guns of various capacities, from mobile household models to huge industrial ones;
Resanta - domestic gas, diesel and electric guns, which have proven themselves to be of high quality and reasonable prices.

Other manufacturers include Inforce, Hyundai, Gigant, Sturm and NeoClima.

Finally, we note that it is worth buying a gun if it is supposed to be in constant operation. If the equipment is needed only temporarily for construction work or at the time of repair of the failed main equipment, then it is more logical to use rental services.

Number 3. Gas heat guns

Gas devices are equipped with a burner with holes through which the gas passes into the combustion chamber. When the fuel burns, heat is released, which heats the walls of the heat exchanger. The fan, as in electric guns, pumps air to the heat exchanger, releasing it from the gun already heated. The fan is powered by the mains, so you still need to connect to a power outlet, but the power consumption will be some 30-200 W, so this heating method will hardly affect your electricity bills.

The gas heat gun can work at the liquefied gas cylinder or be connected to a gas network. Ignition takes place manually or automatically.

Advantages:

• economy in operation;
• high efficiency;
• rapid heating of large areas and uniform distribution of heat;
• for the safety of the user, numerous mechanisms are provided, including overheating protection, flame control system, etc.

Minuses:

• despite all the safety mechanisms, a gas heat gun is more dangerous than an electric one. When burning, oxygen is used, and if the room is not equipped with normal ventilation, then the accumulation of combustion products and a decrease in the amount of oxygen will lead to sad consequences, so get ready to ventilate the room at least occasionally, or organize high-quality ventilation;
• connection to a gas pipeline or a constant change of gas cylinders is required.

These shortcomings fade before the main advantage of gas guns - the low cost of operation. Devices of this type are usually used for heating large premises: warehouses, workshops, industries, hangars. Often gas guns are used on construction sites when it is necessary that the mortars dry quickly or gain strength, and the room is cool and damp. However, small construction teams and private craftsmen do not need to go broke to buy their own equipment - in the cold season, to increase the efficiency of construction, installation and repair work, you can rent a heat gun. In Krasnodar, this service is provided by LLC Professional, which has been selling and leasing construction equipment since 2005. The range of gas heat guns can be found on the page All equipment is new and modern, and the company takes care of its maintenance.

What is used for

Heat guns are very powerful heating devices that can heat even large rooms in a matter of minutes. They also perform a drying function.Because of these features, heat guns are most often used for technical premises - warehouses, garages, etc. On average, a heat gun is 3-5 times more powerful than an electric convector. Given this feature, it becomes clear why it is less often used in everyday life and residential premises.

A good electric heat gun can greatly raise the temperature in the room and dry the air well. Because of these features, it is used as a substitute for central heating. The need for it arises during construction work or in those rooms where there is no other heating system - in this case, you can raise the temperature to a comfortable level for a person only with the help of a gun.

One electric gun has a greater efficiency and heating effect than several electric convectors or other types heating. At the same time, the cost of such heating remains relatively low, respectively, with the help of it you can save.

In practice, heat guns are used:

• In everyday life, heat guns are often used in garages. In winter, cars often freeze through. With the help of a gun, you can dry the car relatively quickly and heat it up, and it will be able to start despite the low ambient temperature. Also, an electric gun is indispensable in those premises where a person has to work for a long time - workshops, garages, service stations, etc. Due to the heating and drying of the air, the conditions of stay in the room become comfortable and safe for humans.
• In construction, guns are used to speed up finishing and other types of work where a quick solidification of materials is required due to temperature and dry air. For example, with the help of guns, the drying of plaster is accelerated.It can also be used in other works such as installing laminate and parquet. For some technological operations, warm, dry air is required, and a heat gun can provide it.

Types and models

The classification of heat guns with a ceramic heater is made according to such features as the shape of the body, the speed of the air mass supply and the power of the thermal element. In addition, devices are portable and stationary. The first ones are used for heating cottages, garages, hangars and building change houses. Such devices are lightweight, easily transported from place to place and have a power of 1 to 3 or more kW. Stationary units have higher power, are less economical and are used to heat large spaces. The modern market offers a large selection of ceramic heat guns.

Room type

The next, no less important criterion for choosing an electric heat gun is depending on the type of room. For example, for a house, you need to buy indirect heating devices, the design of which includes an exhaust gas system. This is due to the fact that in a private house there are people and animals that can be negatively affected by exhaust gases.

Although this point is not relevant in relation to the electric heater, you should still be aware of the importance of indirect heating. If you want to choose a heat gun for a greenhouse or for heating a car, it’s better not to overpay and buy a simpler version of the design.

Another important nuance should be noted right away - if you want to choose an electric heat gun for temporary heating, buy a portable case. If the heater has to work for a long time in one place, for example, in the country, choose a stationary type device that needs to be fixed in a certain place in the room.

Basic device and principle of operation

The heat gun is a mobile air heater for rooms for various purposes. The unit is mainly used for two purposes. The first task is the organization of local heating of exhibition halls, trading floors, warehouses, garages and pavilions.

The second purpose is the quick drying of individual elements in technological operations, for example, fixing French ceilings or interior decoration in winter.

The fan heater has a simple device. The main structural details of the device: a fan, a heating element, a thermostat for offline operation and a thermostat to prevent overheating of the gun

All components are housed in a rugged metal housing equipped with grilles for cold air intake and hot air exhaust. A heating element, an open coil or a fuel tank with a heat exchanger is used as a heat generating unit.

The principle of operation of the fan heater:

1. The "gun" captures the air currents and passes them through the heater.
2. Hot masses are pushed out through a nozzle, being distributed on the room.

The operation of the mechanism is similar to a conventional fan. The only difference is the parallel connection of heating elements that supply warm air.

Universal heat guns

Universal heat guns are used at construction sites and in industrial premises.

We have already written about universal heating boilers that can run on any type of fuel, from electricity to firewood. Universal heat guns can also boast of being omnivorous, but most models run exclusively on liquid fuel - you can pour diesel fuel or kerosene here. They can also work on used engine oil (working out, heating oil), which is important for car services.

Mining costs a penny, but it gives a large amount of heat. It is supplied by many enterprises that collect used engine oil. Universal heat guns are most often used for space heating, but there are also models with blowing fans (like diesel models, they are divided into modifications of direct and indirect heating) - they can be used during construction and finishing work.

Selection criteria

You can understand which heat guns are best for your home if you study their capabilities in more detail. The optimal solution for a dwelling, cottage or apartment is an electric model with a wall mount. The choice of heat guns for technical needs depends on the tasks assigned to them. For heating concrete, performing other construction work, gas or electric models are used. Infrared guns are used in the installation of stretch ceilings.

In this category, you can find mainly electric models. Gas options are the most economical, but they require a separate chimney or forced ventilation of the room, there are restrictions on the minimum area.

The main criterion for choosing a heat gun is its power. To heat a room with a volume of 30-50 m3 by 15 degrees, about 3 kW is needed. Twice as much will be needed for an object of 100 m3. Further proportions are preserved.In addition, on average, 1 kW of energy is required per 10 m2 of a house area - the higher the heat loss coefficient, the greater its consumption. It all depends on the thermal insulation of the object, its area and purpose. When choosing a heat gun for a home among diesel models, it is worth making a test run in order to better assess the quality of the equipment

It is important to pay attention to such moments

1. The presence of leaks, leaks in the area of ​​\u200b\u200bthe fuel tank. A leaky design poses a serious hazard.
2. Metal quality. If, after a few hours, soot appears at the attachment points, we can talk about too thin, low-grade raw materials. The heat capacity of the equipment will be extremely low.
3. The intensity of the flame exit from the nozzle. If the compressor responsible for its supply fails, the fire will be supplied too intensively, not allowing sufficient fire safety to be ensured. It is better to entrust the adjustment to specialists in the store. The absence of such a function is a reason for refusing to purchase.
4. After turning off the fan of the heat gun, it should work for some time for cooling. If it stops immediately, this can lead to the melting of components, sensors, and deformation of the case.

In cheap models, this function is not available, which often leads to device failure.

The best gas heat guns

Gas-type heat guns are characterized by high efficiency (often close to 100%), higher power and performance compared to electrical counterparts. But when using such devices in enclosed spaces, a supply and exhaust ventilation system is required.

How a heat gun works

The device consists of a housing, a fan and a heating element. Outwardly, it is a metal cylinder from which a powerful air stream emanates.

A heat gun should not be confused with a fan heater. There are significant differences between these devices. As an example, this device has a thermostat and a thermostat. How the heat gun principle works:

• the built-in fan blows cold air, which enters through the holes in the case;
• the heat received with the help of the heating element is blown out by a strong flow of air masses;
• adjustable dampers allow you to direct warm air in the right direction.

To operate a heat gun, regardless of the type of heating device, you need electricity. It is necessary to perform the function of heating and rotation of the fan.

What to consider when choosing

A correctly selected parameter will not only help to optimally heat the room, while rationally using electrical energy, but will also keep the gun working for a long time.

Calculation of thermal electric guns can be made according to the formula:

Р=VхТхК, kW

where V is the volume of the room; T - temperature difference outside and inside the room; K is the coefficient of thermal insulation of the walls.

1. K=3…4 - walls made of boards or steel corrugated boards;
2. K \u003d 2 ... 2.9 - brick walls in one layer, a roof without insulation, simple windows;
3. K = 1 ... 1.9 - standard wall, roof and insulated windows;
4. K = 0.6 ... 0.9 - walls made of two layers of bricks, there is additional thermal insulation, high-quality plastic windows, additional thermal insulation of the roof.

The final result calculated by this formula is measured in kcal / hour.

To convert to watts, you need to multiply the resulting number by 1.16.

For rooms with an area of ​​​​5-6 m², 0.5 kW of the device is suitable.

For every 2 additional m², add 0.25 kW to 0.5.

In this way, the required power of the heat gun is determined.

If you intend to use the device constantly in the same room, for example, to give, then you can purchase a stationary gun.

If it is planned to use it as an additional source of heat or the frequency of use is not too high, then it is wiser to take a mobile variety.

Pay attention to the device of the heating element. In rooms where people are often enough, you should choose models with a closed thermocouple. In rooms where people are often enough, you should choose models with a closed thermocouple

In rooms where people are often enough, you should choose models with a closed thermocouple.

Otherwise, the products of combustion of garbage particles that fall on the heating element can adversely affect human health.

A wide range of products allows you to choose the version of the case that best fits into the situation.

You should also pay attention to the material from which it is made - choose the most resistant to thermal effects.

The noise level produced by the gun is of no small importance when it is installed in rooms with people. To avoid discomfort, models with a noise level not exceeding 40 dB are recommended.To avoid discomfort, we recommend models with a noise level not exceeding 40 dB

To avoid discomfort, models with a noise level not exceeding 40 dB are recommended.

If the determining factor is the power of the device, for example, installed on a construction site, then in this case efficiency will be much more important than sound influence.

And, of course, an important factor is the cost of an electric heat gun.

It would be irrational to buy an expensive powerful device for a ten-meter room.

And for large areas, such as construction sites, warehouses, industrial premises, powerful industrial thermal electric guns are needed, the cost of which can be 30-40 thousand rubles.

Taking into account the combination of all these factors, you can choose the most optimal option for an electric heat gun.

No. 5. Infrared heat guns

All the heat guns we have considered earlier have one thing in common - the presence of a fan. It is he who helps to effectively distribute heat throughout the room. Infrared devices work in a completely different way.They do not have a fan, and heating is carried out due to the fact that the device uses infrared rays to heat the surfaces in the room (floor, walls, furniture), and they, in turn, heat the air. The sun works on the same principle. It turns out that the air warms up much more slowly, but people and objects in the radiation zone heat up in the very first minutes after the device is turned on.

Diesel or kerosene is used as fuel. The fuel burns, heats up special tubular heating elements, which tend to emit infrared rays when the temperature rises. So that the elements of the case do not heat up with rays, a mirror surface is located behind the heating element. Infrared heat guns are used when spot heating is needed.

Advantages:

• rapid heating of people and objects in the radiation area;
• almost complete absence of noise, since there is no fan in the design;
• the ability to work both outdoors and indoors;
• security and mobility;
• Efficiency up to 95%.

Among the minuses, one can note the cost of equipment and the same spot heating - it will not work to warm up the room quickly, as, for example, a gas gun does. This is an excellent solution for rooms with poor thermal insulation, for heating outdoor areas, as well as for repair work.

What is better to choose

So how do you make a choice? To choose a good and efficient device, you need to proceed from the purpose of the acquisition: if you need to heat a non-residential premises, then it is better to use a heat gun, and for places with high traffic or crowds of people it is more convenient to limit the flow of cold air from outside with a curtain.

The main purpose of a heat gun is to warm up the room as quickly as possible, while the curtain, first of all, allows you to keep the heat inside. Ideally, these two types of heating can be successfully combined. The only disadvantage of such a tandem is the high noise levels during operation. Therefore, in office buildings where silence is important, thermal curtains are used in combination with other types of heating, such as convectors.

Installation and repair

Heat guns usually do not require complex installation. Mobile electrical equipment does not just need to be connected to the network. If the heater or fan fails, they are replaced with similar parts. Diesel models for heating outdoor objects (with direct heating) are also sold as a set. Before starting work, you need to refuel them, and at the end, allow the fan to cool the case before turning it off. With indirect heating, a special corrugation is used - a sleeve that removes exhaust gases outside the room. They are usually made of metal.

It is not possible to connect a gas heat gun with your own hands to the mains. These works are performed by specialists of resource-supplying organizations. Any unauthorized tie-ins and violation of the wiring diagram during inspection may result in a fine.Heat guns are connected to gas cylinders with flexible hoses in a metal sheath and special fittings; a reducer is used for adjustment. The source of liquefied fuel supply must be located at least 2 m from the burner. Do-it-yourself repair of heat guns is carried out mainly on diesel models. Among the most common breakdowns, we note the following.

1. Failure of the ignition system. It can break down on both diesel and gas guns. The part is pretty easy to replace yourself.
2. Fan motor failure. The fault is easy to diagnose - the fan will not rotate. For repair, you need to inspect the motor, clean the terminals, measure the voltage on the motor winding, examine the insulation. Sometimes it's cheaper to just replace the failed motor.
3. Clogged nozzles. Through them, fuel is injected into the combustion chamber. If injection does not occur, most likely the nozzles are clogged. You can replace a defective part with a similar one purchased in a specialized store.
4. Defective fuel filter. For diagnostics, you will have to open the case, remove the cap from the tank, remove the filter and rinse it in kerosene. After that, it will be enough to purge with compressed air, and then install this element in place.
5. Fan failure. This part is subject to the most intense wear. The wiring can burn out or melt - then it is soldered, replacing another. All other breakdowns require a complete replacement of the part.
