Electric heat guns for heating the room. Heat gun

Among the many heating devices, a heat gun can be said to stand apart. It is distinguished by its ability, in full accordance with its name, to solve the problem of heating a room quickly and efficiently, as well as its suitability for solving some other problems. Next, we will talk about the most practical type of these devices - electric heat guns, and at the same time we will learn how to choose them correctly.

What is an electric heat gun?

They call it a heat gun heating device, in which the heating element is blown with air using a fan. Contact with the heater causes the air temperature to rise, after which it enters the room in a powerful flow.

With a power of up to 2 kW, the heat gun may have a plastic body. This device is usually called a fan heater and is intended for domestic use. More powerful models are equipped exclusively with a metal body, which has the shape of a pipe. The latter circumstance gives the device a resemblance to a cannon.

Electric heat gun body high power made from steel sheet

When operating any heating device that is not equipped with a fan - a radiator or convector - the heated air spreads into the room due to convection. This process, firstly, is quite lengthy, and secondly, it is not able to cover a spacious object such as a warehouse or hangar: due to local heat loss, the slowly moving air has time to cool down before it penetrates into the remote corners of the room.

A heat gun works differently. By driving the air with a fan, it provides forced mixing, due to which the room warms up very quickly, and the heat spreads evenly even over a fairly large volume.

The heat from the gun spreads throughout the room thanks to the fan built into it

The disadvantage of a heat gun is that it makes noise when operating. Therefore, in residential premises with a standard area, the use of a convection heater will be more comfortable.

Heating a room is not the only function of a heat gun. Essentially, it is a large and powerful hair dryer, hence it can help with the following:

• dry vegetables or fruits;
• heat the polymer stretch ceiling so that it can be stretched, as well as roofing felt or other roofing material roll material to give it elasticity before styling in cold weather;
• dry the freshly laid plaster, screed or paint.

In addition, if you turn off the heater, the heat gun can be used as a fan.

Modern heat guns are equipped with protection against overheating. Many models have a controller and a connector for connecting an external temperature sensor, thanks to which the heater independently maintains the temperature in the room set by the user.

Along with electric heat guns, fuel heat guns are produced, in which heat is released by burning gas, diesel fuel, waste mineral oil and even solid fuel. But for a number of reasons electric version is the most convenient.

Advantages of electric guns compared to other types

This device benefits from the following:

1. The design is extremely simple: a piece of wire made of a material with high electrical resistance. In fuel analogues, this role is played by a burner or nozzle that is more complex to manufacture, and in addition, a number of additional elements: in gas - solenoid valve, in diesel engines - a fuel pump, a filter and a diesel fuel tank.
2. A simple device provides several benefits at once: low cost, light weight, compact size and simple and inexpensive repairs.
3. There is no exhaust or unpleasant smell.
4. The noise level is relatively low since only the fan makes noise. In fuel heat guns, the burner also makes noise, and in diesel heat guns, the fuel pump drive also makes noise.
5. An electric heat gun is safer: the user is not at risk of fuel leakage followed by fire or explosion. Absent open flame, which makes the device safer in terms of fire (if the supply network is not overloaded). There is also no need to fear poisoning from fuel combustion products. True, an electrical appliance becomes dangerous in conditions high humidity, but only in the normal version. If the gun is specially designed for wet rooms, that is, it has high class moisture and dust protection, connected with grounding and through an RCD, the risk of electrical injury is reduced to zero.
6. Unlike fuel analogues, electrical unit does not require refilling, therefore, it can work for as long as desired without user intervention.
7. Also, no maintenance is required, whereas analogue fuel heaters need to be periodically cleaned of carbon deposits, and in diesel heat guns the fuel filter also has to be serviced.
8. The heater power can be adjusted within the widest range - from zero to maximum. The nozzles and burners of fuel heat guns are mostly designed for a constant fuel supply rate; accordingly, it is impossible to reduce their power without loss of combustion quality. Modulated burners, which appeared relatively recently, allow you to regulate power, but not as flexibly as electric heaters. In addition, such burners are much more expensive than conventional ones.

The statement about the practicality and convenience of electric heat guns is not marketing ploy, it is quite reasonable. But the disadvantages should also be taken into account:

1. High cost of electricity. Operating a fuel gun, even though some of the heat produced is removed along with the smoke, is still cheaper than an electric one.
2. Dependence of power on the capabilities of the supply network. But in most cases these possibilities are not so great. The household electrical network is designed for maximum load within 7–10 kW. And the point here is not only in the capacity of the electric cable: one of the users, who wanted to connect a 15 kW electric boiler in a private house, had to pay for the replacement of not only the cable, but also the transformer at the substation. A fuel-fired heat gun can, in any conditions, “produce tens of kilowatts of heat,” and it consumes electricity in very modest quantities - only to operate the fan.

Specifications

Electric heat guns are characterized by the following parameters:

1. Maximum power consumption. For the most productive models, this parameter can reach 30 kW or more. In fact, this is the power of the heating elements (only a few tens of watts are spent on fan operation), and if you consider that Electrical efficiency heaters is almost 100%, then this parameter can be equated to heating performance. That is, we can assume that a heat gun that consumes 5 kW of electricity will also generate heat with a power of 5 kW.
2. Partial power consumption. Indicated for devices with stepwise power regulation and means the power of one stage.
3. Fan performance. This characteristic is linked to the power of the heaters. With a power of 1 kW, the fan usually operates with a capacity of 120 m 3 /hour, with a power of 3 kW - with a capacity of 300–320 m 3 /hour.
4. Power consumed in ventilation mode. Insignificant value. For example, a fan with a capacity of 500 m 3 /h consumes only 30 W of electricity.
5. Voltage. Models with a power of up to 5 kW are designed for connection to a 1-phase network with a voltage of 220 V. More powerful ones have a 3-phase design, that is, they operate with a voltage of 380 V.
6. Rated current. Using this characteristic, you can determine whether the supply network can withstand the load from the heat gun. If the current rating is not specified, it can be calculated by dividing the power consumption by the voltage (I = W/U).
7. Heating area with a ceiling height of 2.5 m. This is an approximate figure, which is calculated from the consideration that for heating every 10 sq. m of area at the specified ceiling height requires 1 kW of heat. That is, in the characteristics of a heat gun with a power of 5 kW, in the column “Heating area...” the value of 50 m 2 will be indicated. It should, however, be understood that these are very average data, because the amount of specific heat loss, namely the energy consumption for heating depends on it, can vary greatly for different buildings with different volumes, glazing and wall materials.
8. The temperature difference between the air flow at the inlet and outlet in the maximum heat output mode. This value depends on the power of the heaters. For the lowest-power devices it is 20–40 0 C, and a gun with a power of 18–20 kW can heat the air at 140 0 C.
9. Maximum valid time continuous work.
10. Minimum duration of pause between maximum sessions of continuous work. Typically, the maximum operating time and pause duration are indicated as a fraction. For example, the entry “24/2” indicates that the heat gun can work non-stop for 24 hours, after which it will be necessary to take a break for at least 2 hours.
11. Dust and moisture protection class. It is designated by the letters “IP”, followed by two numbers: the first indicates the level of protection against dust, the second - against moisture. In the standard version, heat guns have a dust and moisture protection class IP
12. Electrical protection class. All heat guns with a metal body have electrical protection class I: a grounding wire is connected to the body and other live parts, which is connected to the grounding circuit through contacts on the plug and socket.
13. Dimensions.
14. Weight. As already mentioned, electric heat guns are relatively lightweight. The 2 kW model in a plastic case weighs only 0.86 kg. A heater with a metal body with a power of 3 kW weighs 9 kg, and models with a power of about 20 kW weigh within 20 kg.

An important point: if the fan performance for any reason turns out to be less than the calculated one, the heat gun will often be turned off by the overheating protection system.

Main manufacturers

Electric heat guns are quite popular equipment, and accordingly, many companies produce them. The most famous include such manufacturers as Ballu, Zubr, Interskol, Inforce.

Ballu

This Dutch company has production facilities in Russia, so its products in our country are distinguished not only by their quality, but also by their availability.

Ballu heat guns have a distinctive design, equipped with thermostats and vibration damping elements

An example is the Ballu BHP-P-3 heat gun.

The following can be said about it:

• power is 3 kW (step adjustment is provided);

Fubag

A German manufacturer, quite well represented on our market. Among others, it offers the Fubag Sirocco 20 M model with the following characteristics:

Cost: 4160 rub.

Timberk

Manufacturer from Sweden. The model most often purchased from us is Timberk TIH R2S 3K. Here is its brief description:

Cost: 3930 rub.

Master

The company is registered in the USA. Its products are extremely expensive. For example, the Master B 2 EEB model with a power of 2 kW costs about 5 thousand rubles. But this manufacturer has a range of heat guns for all occasions. Thus, the Master B 30 EPR device, with a power of 30 kW, has a pipe for connecting a flexible air duct.

The ability to connect a flexible air duct to the Master B 30 EPR gun allows you to heat several large rooms with one unit

Thus, if there is a network of air ducts, one heat gun can heat several large rooms of a factory or warehouse complex. Thanks to the chassis, the device is mobile. The cost of this “monster” is 71 thousand rubles.

How to choose an electric heat gun

Choosing a heater begins with selecting its power. It was said above that the characteristics of the device often indicate the heated area, but this data is purely for reference and cannot be trusted. Ideally, you should order a building engineer or heating engineer to calculate the heat loss of the building, which will help you select the power with sufficient accuracy.

If this is not possible, you can perform the calculation yourself using a very simplified method. One single formula is used: Q = (V x dT x K) / 860, where Q is the required power of the heat gun, kW; V is the volume of the room, m3; dT - the difference between the desired indoor and outdoor air temperatures during the coldest period of the year, 0 C; K is a dimensionless coefficient, which is taken in accordance with design features structure and the degree of its insulation for buildings:

• built using modern energy-saving technologies (all enclosing structures are insulated with modern highly efficient thermal insulators, sealed windows with double-glazed windows are installed): K = 0.6–0.9;
• built and insulated using traditional technologies and equipped with non-sealed windows regular sizes: K = 1–1.9;
• light with walls half a brick thick, single glazing and a simple roof, possibly with minor insulation (outbuildings, etc.): K = 2–2.9;
• frame with single-layer cladding with boards or corrugated sheets and without insulation (hangars, warehouses): K = 3–4.

Calculation example

As an example, let’s calculate the power of a heat gun for a room in an ordinary house (assuming K = 1.4) with plan dimensions of 4x5 m and a ceiling height of 3 m. Let us set the condition that:

• the heater will be used at an outside temperature of -5 0 C;
• the temperature in the room must be maintained at +20 0 C;
• temperature difference inside and outside dT = 20 – (-5) = 25 0 C.

The volume of the room will be V = 4 x 5 x 3 = 60 m 3.

Then the power of the heat gun will be equal to Q = (60 x 25 x 1.4) / 860 = 2.44 kW.

Heater type

Three types of heaters are used in electric heat guns:

1. A spiral made of nichrome or other alloy with high electrical resistance.
2. Tubular electric heater (TEH). This is the same spiral, only placed in a copper tube filled with sand.
3. Ceramic plates. The same heating coil is embedded in the plate.

The first option - the spiral in its pure form - is the cheapest, but it has important drawback: The metal heats up very strongly, so that dust burns on it and produces an unpleasant odor.

The heating element and ceramic plate do not heat up as much, but they are not inferior to the spiral in performance, since they have a much larger surface area. Dust does not burn on them, but the price of such heaters is slightly higher.

Additional functions

Here's what else you need to pay attention to when choosing a heat gun:

1. If you plan to move the device from place to place, you should choose a model with a comfortable handle. During operation, heat guns heat up quite strongly, so if there is no handle, moving the device will be very difficult.
2. It is good if the device has tip-over protection. It usually takes the form of a spring-loaded lever protruding from the support base and connected to a switch. When the gun is in the correct position and its sole is pressed to the floor, the lever is recessed and the associated switch is in the “on” position. If the heater falls on its side, the spring will push the lever outward, as a result of which the switch will be switched to the “off” position.
3. Protection against overheating is also very important, but modern heat guns are equipped with it mandatory.
4. Availability of filters. Models with filters are designed for use in very dusty rooms. It is important to remember to periodically change filters or wash them if you are using reusable products.
5. Availability of an air humidifier. If there is no open container of water in the room, then relative humidity the air temperature decreases noticeably when heated.

This process occurs when using any heater, not just an electric one. It is due to the fact that the maximum amount of steam that can be in a certain volume of air depends on the temperature of the latter. Due to the low temperature, the air coming from the street contains little moisture. When it heats up, its ability to dissolve steam in itself increases, but the amount of steam remains the same and the air becomes, as they say, dry.

This air is unpleasant to breathe, it causes drying of the mucous membranes and skin, and also leads to the fact that wooden furniture and decoration dry out. To eliminate this problem, some models of heat guns are equipped with an air humidifier - a device that quickly saturates the internal air with water vapor.

Along the way, let’s debunk another myth: none of the electric heaters, regardless of the principle of operation, leads to “burnout” or “burning out” of oxygen. The concentration of the latter can decrease only during the combustion of any fuel. Perhaps the legend about burning out oxygen is due to the fact that, as already mentioned, heated air, due to its dryness, can be unpleasant to breathe.

If the heat gun is intended to be used in a room with high humidity, you should choose a model with a splash-proof housing and dust- and moisture-proof switches.

Also convenient are devices in which the direction of air supply can be changed using blinds installed in the outlet.

Choosing a heat gun for the garage and cottage

When calculating the power of a heater for a garage, the K coefficient should be taken equal to 2.45 (average between 2 and 2.9), and for a summer house - 1.45, that is, as for an ordinary house.

Since a country house is a residential space with permanent residence, a heat gun with heating elements or ceramic plates should be used here. They, as mentioned above, do not give off the smell of burnt dust.

For a garage where the user stays for a relatively short time, a gun with a heater in the form of spirals is also suitable. It would be good if it was equipped with rollover protection, since such incidents are especially dangerous in a garage: the direction of hot air after the gun falls will change and oil and gasoline can get into its area of ​​effect. And since these substances are flammable, a fire is inevitable.

For the gun in country house Having a humidifier is highly desirable. It can also be purchased separately.

The humidifier can be replaced with a wet towel suspended on a stretched rope or a basin filled with water.

Economical heat guns

The high cost of electricity forces buyers to look for models that use this resource as rationally as possible. These are heat guns equipped with a thermostat. When the set temperature is reached, the device will turn off automatically; accordingly, exactly as much electricity will be spent on heating the room as needed.

Heat guns without a thermostat have to be turned off manually. The user does not always do this in a timely manner, so the heater, as a rule, even after reaching a comfortable temperature, continues to pump heat into the room, leading to unnecessary overheating, increased heat loss (we remind you, they depend on the difference in temperature inside the room and outside) and, accordingly, , to excessive energy consumption.

You can pay attention to heat guns with heaters of a special design, which, in comparison with conventional ones, provide higher heat transfer. These include, for example, RexWatt brand devices. They are equipped with a heater made in the form of a cylinder (the manufacturer calls it a nozzle). Thanks to this shape, the air passing through the gun has time to heat up to a higher temperature than in the case of a conventional heater.

The heating elements in RexWatt electric heat guns are cylindrical in shape

This feature, in turn, allows the use of a more efficient fan. If air is driven through a conventional heat gun with a power of 3 kW in a volume of 300 m 3 /h, then through a heater from RexWatt at the same power - 500 m 3 / h.

Thus, we can say that the RexWatt heat gun can replace two conventional ones, since it is able to provide circulation and, accordingly, distribute heat over an area twice as large as its conventional counterpart.

However, it should be taken into account that the heat itself does not increase any more - both in a conventional gun and in the model from RexWatt it is produced with a power of 3 kW.

A heat gun allows you to get by with one device where several radiators or convectors would be needed. At the same time, it can act not only as a heater, but also as a large, powerful hair dryer, which makes these devices very popular. By carefully studying the recommendations outlined above, you will be able to choose the most suitable model for yourself, using your funds in the best possible way.

Heat guns have a wide range of applications. They heat living quarters and are used for construction purposes. Operating on various energy sources, they are highly efficient heat sources. And within the framework of this review, we will consider such a device as a gas heat gun for residential premises and premises for other purposes. These units operate on gas fuel and are characterized by high efficiency.

We will cover the following topics:

• Design features of gas heat guns;
• Purpose of gas heat guns;
• Their varieties;
• The most popular models of heat guns.

After reading the material, you will receive maximum information about these units.

Design and principle of operation

As part of our reviews, we have already looked at high-performance heat guns that run on liquid fuel. They have high efficiency, but are sources of unpleasant odors, since the fuel in them does not burn 100%. An alternative to them is gas units, working on natural or liquefied gas(most often liquefied gas is used - a little later we will explain what this is connected with).

A gas gun for heating rooms is a relatively simple interior design a unit that uses gas for its power. By burning the incoming fuel, this unit produces a large number of heat that is sent into the room using powerful fan. The heart of the device is a burner with an ignition system - simple piezoelectric elements and electric ignition systems with electrodes are used here.

The body of a gas heat gun is made of durable metal, since during operation its surface becomes very hot.

The device of a gas gun is as follows:

• Thermostat – provides temperature control;
• Fan - it provides the burner with oxygen and sends heat to the heated rooms;
• Control system – includes a thermostat and a start button;
• Burner is a module equipped with a nozzle and providing the creation of a flame torch.

Some models of gas heat guns also contain heat exchangers - they serve to safely transfer heat to heated buildings and rooms.

A gas gun cannot work without electricity, since its essence is to “shoot” heat under high pressure, characterized by high productivity. Without a fan, she would turn into the most simple burner, which cannot boast of high efficiency. Therefore, it is almost impossible to find units that can operate in a completely autonomous mode - a power source is required here.

The gas heat gun is enclosed in a durable metal casing and its appearance really resembles some kind of weapon that shoots cannonballs. Only instead of cannonballs, hot air flies out of its mouth. Due to the built-in fan, heated air masses are evenly distributed throughout the heated volume. Models with a thermostat monitor the temperature generated, providing precise temperature control.

Onboard thermostats in gas heat guns monitor the temperature of the intake air - when a predetermined threshold is reached, the burner is temporarily turned off.

To power gas heat guns for residential premises, two types of fuel are used - main gas or liquefied gas from a cylinder. In the first case, everything is not so simple, because to connect to the highway you need permission. Therefore, liquefied fuel is most often used to power the units. The gas cylinder for a heat gun is the same cylinder that is used in conjunction with conventional kitchen stoves. Its volume is not limited in any way; connection to heat guns is carried out through a reducer to reduce pressure.

Purpose of heat guns

In essence, such a gun is large gas burner. Only the fan located behind it makes it a heater.

Heat guns are most often used for heating non-residential premises - these can be various hangars, production workshops, buildings under renovation and warehouses. At the same time, people may be there at the time of work if adequate ventilation has been provided. As for residential premises, here they are used much less often - after all, less bulky and more accurate heating devices with a low noise level are more suitable for living rooms.

In residential premises, thermal gas guns can be used during repair and finishing work. With their help, the plaster is dried and the temperature is increased for faster drying of concrete screeds. They are also used during installation suspended ceilings– here you need a relatively high temperature necessary to stretch the fabric. And thanks to the directed heat flow, builders have the opportunity to carry out spot drying.

Another area of ​​application is ensuring air circulation in rooms. To do this, the heat gun is turned on in fan mode, without starting the gas burner.

Main varieties

All these units are divided into two large categories - with direct heating and with indirect heating. Heat guns with direct heating send combustion products into heated rooms along with hot air. They are not toxic, but this does not make breathing easier. But such units are characterized by high efficiency. For their work it is necessary good ventilation, operation in closed buildings and structures is prohibited.

An indirectly heated gas gun is a more progressive, but more complex unit. Here, a closed combustion chamber is used with combustion products vented outside through a chimney. By blowing through the combustion chamber, the fan drives clean warm air into the room. True, such heat guns are very rarely found on sale, and their cost hits the buyer’s pocket hard.

Launching a heat gun

As we have already said, gas heat guns are powered by a gas cylinder (mostly). The startup process looks like this:

Due to the presence of a chimney, indirect heating heat guns are used as stationary systems heating, but completely eliminate the possibility of combustion products entering the heated room.

• We screw the reducer with a hose to the gas cylinder;
• Connect the hose to the heat gun;
• We connect the unit to the electrical network;
• Press the start button and set the desired temperature.

The fan will turn on, the igniter will work (in some models the gas is ignited by a button with a piezoelectric element) - and after a few seconds, the room will begin to fill with warm air.

In indirect heating models, it is necessary to bring the chimney outside - flexible corrugated pipes are used for this.

Advantages and disadvantages

Let's see what are the pros and cons of gas heat guns for heating residential and non-residential premises. Let's start with the positive features:

• Economical - for example, for a 30 kW heater, gas consumption per hour will be just over 2 kg;
• No strong odor combustion products - fuel burns almost completely;
• Comparatively miniature - unlike diesel units, there is no tank.

Negative features:

Some craftsmen who want to save money make heat guns themselves. The safety of such crafts leaves much to be desired. We advise you not to resort to using such units.

• Unsafety - this feature is inherent in all gas appliances, including kitchen stoves;
• The need to use electricity – at sites without electrification you will have to use a generator;
• Difficulty connecting to the highway - this requires a special permit.

Nevertheless, gas heat guns continue to be in demand equipment, especially in the construction industry.

How to choose a suitable heat gun

If you are going to buy a gas heat gun, focus on its performance and power, comparing these parameters with the heated volume. Remember that for every 10 sq. m area requires at least 1 kW of heat. If you plan to use the unit for construction purposes, for drying plaster or installing suspended ceilings, you should choose a more powerful model.

Remember that the greater the power, the greater the noise level and the greater the gas consumption. If the task is to heat a small basement, cellar or greenhouse with a heat gun, choose small-sized models - they are somewhat similar to ordinary fans. To heat large hangars and warehouses, more efficient units will be needed. If people work in the premises and there is no ventilation, take a closer look at indirect heating heat guns.

When choosing a heat gun in the catalog of a particular store, carefully read the descriptions - all the characteristics and features are indicated there. And by looking at the Yandex.Market catalog, you can read the reviews. By the way, they all indicate the high efficiency and unpretentiousness of these devices.

Another selection criterion is the manufacturer. If you choose between domestic devices and foreign ones, then you won’t be able to give someone special preference. Russian and foreign brands make good gas heat guns, characterized by endurance and good technical characteristics. But if we look at the ratings, they are headed by the Master brand.

Popular models

Enough theory - let's move on to practice. Now we will look at the most popular models of gas heat guns. All of them are direct heating models.

Master BLP 33 M

Before us is one of the simplest gas heat guns, the price of which varies between 11-12 thousand rubles. The unit is devoid of thermoregulation, its productivity is 1000 cubic meters. m/hour is a good indicator. The heat gun turned out to be compact, light and powerful. Its weight is only 9 kg and its power is 15 kW. The model is aimed at use for construction purposes. And in order to ensure long-term and continuous operation, several gas cylinders can be connected to it at once.

This is a gas heat gun with a thermostat and temperature control, which will literally cost you 9-10 thousand rubles. The device is equipped with a tilt angle adjustment system, and it is also extremely easy to operate - the thermostat and switch are combined into one single handle. Her thermal power is 50 kW, but the heated area is only 300 sq. m. Fuel consumption varies from 2.2 to 3.2 kg/h. Despite the low price, this heat gun cannot compete with the model described above.

The presented model is distinguished by its compactness, which makes it easy to transport. It is designed to run on liquefied gas, maximum flow is 0.8 kg/hour. The weight of the device is a little more than 5 kg. The kit already includes a hose and a reducer - you do not have to purchase them separately. As in the previous unit, the tilt angle can be adjusted here, and the stable stand prevents accidental tipping. This is an excellent heat gun for a mobile construction crew.

We have quite powerful gun with an advanced ignition system. Its power is 31 kW, maximum performance is 1000 cubic meters. m/hour. This is quite enough for construction needs and heating of large premises. The heat gun is equipped with a temperature control system. As for ignition, the burner contains three electrodes at once - this ensures instant ignition of the incoming gas.

In order to extend the service life of the unit, the manufacturer has equipped it with overheating protection. As soon as certain indicators are exceeded, the equipment will turn off the gas supply and resume it after cooling. The heat gun also provides protection for the body from corrosion - for this purpose the body is coated with a special coating. The heat gun is unpretentious in operation and economical - it burns only 2.27 kg of gas fuel per hour.

The cost of this unit is about 10 thousand rubles - an excellent choice for heating rooms for various purposes.

It would be strange not to mention this name in our review famous brand. The presented heat gun is characterized by compactness and high power - 17 kW. Its capacity is 270 cubic meters. m/hour. Let's consider the main advantages of this unit:

• Low cost - it is about 5,000 rubles;
• Gearbox and durable hose in the original configuration;
• Reliable and durable burner with protection against ignition at low gas pressure;
• Complete shutdown in case of power failure;
• Almost complete combustion of fuel.

There is no electric ignition here; a simple piezoelectric element is responsible for this. The heat gun is also equipped with overheating protection.

Why the manufacturer did not give this gas heat gun a normal model designation is not entirely clear. In general, the unit is not bad, its thermal power is 10 kW, and its maximum productivity is 300 cubic meters. m/hour. Moreover, during this hour it consumes only 727 grams of fuel (propane or butane). The gas burns completely, without producing a characteristic odor.

The heat gun turned out to be compact - its dimensions are 435x230x305 mm. This is an excellent choice for construction crews and anyone else who needs a portable gas heater with decent performance. The official price from the manufacturer is 4,499 rubles, which makes this heat gun one of the most affordable devices.

Together with this model, heat guns with increased power are produced - up to 85 kW. They differ in increased dimensions, but this does not change the functionality.

When choosing a heat gun, you should decide for what purposes they will be needed: heating a house, garage, greenhouse, greenhouse, or for construction needs.

In any case presented, to correctly select an electric heater, you need to determine its power, design characteristics and the manufacturer.

The first thing you should pay attention to is the parameters suitable for normal and quality work heat gun. It is necessary to select according to power and suitable electrical voltage.

For the first characteristic, there are two main calculation options. A simple definition is that for heating 10 sq.m. rooms need at least 1 kW electrical power. And if your room is 4x6 meters, simple calculations will show that you need to purchase a heat gun with a power of at least 3 kW.

We got this indicator like this: 4 * 6 = 24 sq.m., taking into account that the electrical power reserve must be at least 20%, we calculate: 2.4 * 1.2 = 2.88 kV. The closest value will be 3 kW, and this is what you need to select for heating this room.

The second calculation method is more accurate, and we recommend using it when choosing a heat gun for your home. In this case, the formula does not take into account the area of ​​the room, but its volume and the thermal conductivity coefficient of all walls. And the formula takes the following form: P= (V*dT*Kt)/860, where:

V is the volume of the room, calculated as the area multiplied by the ceiling height, m3;

dT - temperature difference between the room and the environment;

Kt – thermal conductivity coefficient. An indicator from 0.6 to 1 is for walls with good thermal insulation. With average thermal insulation - from 1 to 2. With poor thermal insulation - from 2 to 3. Old houses - from 3 to 4.

860 is the number of kcal in 1 kW.

Required thermal power

To make the essence of the calculation more clear, let's consider it with an example. You have decided to purchase an electric gun to heat your car in the garage. The garage volume is 4x6 meters, the ceiling height is 3 meters. The temperature inside the building is +15C, outside -20C. The temperature difference is 35C. The garage is insulated quite well, we select the thermal conductivity coefficient 1. As a result of all the indicators, the formula takes the following form: 72*35*1=2520 kcal/hour.

To convert the value to kW, you need to divide it by 860. This turns out to be 2.93 kW. Taking into account the required reserve, you need to choose a heat gun of at least 3.5 kW, and this will be quite enough.

It should be noted that there is currently conditional classification all thermal devices by power. It is generally accepted that up to 5 kW these are heat fans, and above this power – heat guns.

Heat gun device for home

No less important technical indicator operating voltage is considered. There is a heat or electric gun with a power above 20 kW, which requires a three-phase 380 V network to operate.

This point must also be taken into account when choosing a heat gun for heating a garage or home. To do this, it will be necessary to replace the entire house with a new, more powerful and reliable one.

Thermal devices with a power of no more than 7 kW can be connected to a 220 V network, of course, if the wire cross-section allows. Before connecting ideal option

There will be a calculation of the cable cross-section based on its power and electric current, to check the wiring with such current loads.

The last thing you need to pay attention to when choosing a heat gun for your home is the duration of its operation. When heating a room with a gun, it must work without interruption for a long time. Therefore, manufacturers of these devices indicate on the body of the guns the values ​​24/1 or 24/2, and this means round-the-clock operation with a slight break of 1-2 hours.

In addition, to correctly select an electric heat gun based on its properties and performance, pay attention to the noise level during its operation and the temperature range. Modern thermal devices must operate at temperatures from +5C to +40C.

Types of premises

• Heat guns are:
• Electrical
• Diesel
• Gas

Infrared Next, quite a few important criterion When choosing a heat gun for your home, the type of room in which it will be used is considered. For example, for a home you need to buy an indirect heating device, the design of which includes a special system for removing harmful gases. This is due to the fact that there may be people and animals in the house that can be negatively affected by waste gas fumes. However, in relation to the electric heater this moment

does not apply, but you should still understand the importance of indirect heating. When choosing a heat gun for a greenhouse, it is better not to overpay and buy a simpler type of design. Let's note one more important point

– if you want to purchase an electric gun for seasonal heating, then buy a portable housing. When heating for a long time in one place, for example, in a country house, choose a stationary type heating device that will need to be fixed at a certain point in the room.

Additional characteristics of heat guns

Types of heat guns for the home It is also very important when choosing a thermal heater to pay attention to the following interesting points:

1. A heat gun for heating must have a temperature regulator, at least of a stepped type. The thermostat allows you to control the efficiency of an electric heater.
2. The gun must have a function automatic shutdown with great overheating. If the case accidentally falls, and if the heating element overheats, a fire hazardous situation will not arise, because a special sensor - a thermostat - will work.
3. It is believed that a metal case is much better than plastic and composite. Because metal is much stronger, and in the event of a sudden power outage, a hot heating element will not harm the metal body of the gun. Plastic can easily melt and cause a fire.
4. Cylindrical-type devices are able to warm up rooms several times faster, because... their heating element is a spiral. This option is suitable for heating a garage in winter periods for faster heating of the machine.

Rectangular heater gun more rational to use for heating a private home, this is due to their type heating element- mesh, which does not dry out the air and is less dangerous in terms of spontaneous combustion.

The cold climate motivates us to study the top rating of the best heat guns for home and garden. Compared to conventional heaters, heat guns can quickly heat an apartment, a frozen cottage, a production workshop or a warehouse. The main thing is to define the selection criteria.

Having come to the idea that you need to purchase a heat gun, you immediately find yourself faced with the question: “How to choose it?” The answer is simple. It is necessary to rely on such criteria as the volume of the room, the number of people present there, and what type of fuel will be used, since most of the modern guns begin to function on gas, diesel and electricity. To calculate the thermal power required for your room, a simple formula was invented: V x T x K = kcal/h. One kilowatt is equivalent to 860 kilocalories per hour.

• V is the volume of the room that needs to be heated;
• T is the temperature difference;
• K is the dissipation coefficient, depending on the type of construction of the house and its degree of insulation.

But you shouldn’t trust the formula entirely, since circumstances play a decisive role. That is, the quantity window openings in the house, the number of doors located and, of course, the height of the ceiling.

The heat gun market is constantly moving, expanding, something new appears, but in general, if we summarize, we can distinguish three types: electric, gas and diesel guns. Each existing type of gun has its own advantages and disadvantages.

Video explanation for calculating the power of a heat gun:

Electric guns

When there are no electrical problems in the room, then good option electric guns are becoming the most affordable and easy to use. On what principle do these heat guns work? Of course, from the network. If the gun model has a power of up to 5 kTv, then it is powered from a 220 volt network; if the gun is more powerful, then a 380 volt network is required.

Their mobility, ease of use, and the absence of the need to use other fuels have brought them well-deserved popularity, both in everyday life and in construction.

The heat is distributed throughout the room due to the fact that the fan blows it and distributes it evenly throughout the room.

Gas guns

Gas guns have two undeniable advantages - they are low price and light weight of the models. Their power varies from 10 to 100 kTV, although there are more. Gas guns operate on gas, which is supplied through a cylinder reducer or thanks to a centralized gas network. When the gas burns, the heat exchanger heats up. The air passing along the heat exchanger is also heated, thus creating heat in the room.

Gas guns are very economical, but there is still a drawback. Liquefied gas in cylinders cannot be purchased everywhere, and it is difficult to stock up due to a number of storage requirements.

Diesel guns

Diesel guns operate on fuel such as diesel fuel and have a common operating principle with gas guns, although their design is more complex.

Among the advantages of guns, it is worth noting their remarkable cost-effectiveness. By filling the gun once with diesel fuel, you can be provided with continuous 10-15 hour operation of the equipment. Delivery of diesel fuel is safe and is not connected to the gas main. Well, the power of diesel guns is not inferior to gas guns.

The disadvantages of diesel guns are their heavy weight and the fuel, which contains contaminants. Because of the last point, they need to be used in non-residential premises where there is good ventilation.

Heat guns for direct and indirect heating

Speaking about diesel guns, it is worth noting that they are divided into two types: direct and indirect heating. This means that a direct heating heat gun evaporates all combustion products directly into the air. Accordingly, it would be advisable to use a direct heating diesel gun for open areas, for example, construction, or in non-residential premises.

An indirect heating heat gun has a special exhaust system for combustion products, which means it can be used to warm up unventilated rooms.

Safety

Many heat guns, especially gas ones, begin to burn oxygen during operation, so it is necessary to ensure continuous movement fresh air. It is best to look at gun models with sensors that clearly monitor fluctuating oxygen levels. Or, if there is no ventilation at all, look at the options for heat guns, which, fortunately, are a great choice.

Video review of the device characteristics:

Quickly heat a spacious room with heating radiators or other convector heaters impossible. The heat from the appliances spreads too slowly through the heated room due to natural convection, so an electric heat gun with forced circulation air.

The powerful fan heater is capable of as soon as possible heat almost any size room.

A floor fan heater (also known as a “heat gun”) is a household or industrial heating device that, in addition to the heating element, has a built-in fan. The first heats the air inside the housing, and the second pushes it into the heated room.

Moreover, the circulation process occurs continuously and with high speed. This is the reason for the high heating efficiency large areas this type thermal equipment. When operating through a fan heater with a power of only 2–3 kW, about 200–300 cubic meters of air mass passes per hour.

Without a continuously running fan, a heat gun would be of little use; it is only thanks to it that the heater in question is so efficient and productive

Using a heat gun to heat:

• construction sites;
• garages and workshops;
• premises for agricultural and industrial purposes;
• living rooms;
• greenhouses;
• warehouses.

It is also often used for heating or drying various surfaces(stretch ceilings, plastered walls, etc.). The electric fan heater does not emit exhaust gases or toxins during operation. From an environmental point of view, this equipment is completely safe and harmless.

An electric heat gun should not be confused with its gas or diesel counterparts. It is difficult to call them environmentally friendly. With heated air, at a minimum, carbon dioxide comes out of them, large volumes of which are dangerous to health. Electric heaters They are freed from this; by definition, nothing is burned in them to produce thermal energy.

An electric heat gun should not be confused with a gas, diesel or infrared one - in the first two cases a different energy source is used, and in the second the principle of heat transfer has been changed

An infrared heat gun is similar to a fan heater in design and appearance. However, there is no fan as such. The transfer of thermal energy here occurs not through forced air exchange, but through infrared radiation. That is, heat in this case is transferred directly to heated surfaces and objects using IR rays, and not through preheating the air.

Advantages and disadvantages of the unit

Among the many advantages of a heat gun operating solely on electricity are the following:

1. Possibility of installation in unventilated rooms.
2. Long period of continuous operation.
3. No open fire.
4. Availability of automatic control with thermostat.
5. Receiving heat immediately after connecting to the power grid.
6. There is no need to constantly add combustible fuel.
7. Possibility of using the gun as a regular fan.
8. High efficiency when heating large rooms.
9. Small dimensions.
10. Versatility in terms of placement.

The fan heater does not emit unpleasant or harmful substances into the air. There is simply nothing to burn in it. Occasionally, when operating this appliance, a burning smell appears for a short time after power is turned on. This is due to buildup on the heating element and protective grille dust. If the gun is kept clean, then this will not happen.

You can even heat your home with a fan heater (there are no gas emissions from its operation), problems may arise only with drying the air

The electric heat gun is able to work unattended and continuously for several days. It does not require adding fuel. At the same time, the presence of automation guarantees that the temperature in the room will be maintained at the required parameters without human intervention.

Warming up the spiral, which heats the air in the heat gun, after feeding electric current happens in a matter of seconds. Heat almost immediately begins to flow into the heated room. In this regard, the equipment under consideration greatly outperforms other heater options.

Fan heaters are extremely easy to use. It is only necessary to prevent dust from accumulating inside, which will emit smoke when the coil is turned on. They can be placed on the floor, wall and even on the table. The lineup This thermal equipment is extensive. You can find an option for any placement and any size.

The fan heater has only three disadvantages:

1. “Burning” oxygen and “drying” air.
2. High noise level when the fan is turned on to maximum.
3. Attachment in the electrical network.

When an electric heat gun operates, the air around the heated coil is naturally dried. As a result, the overall humidity in the room gradually decreases, and it is impossible to avoid this. A similar situation occurs with oxygen: it gradually burns out due to the contact of air masses with a hot heating element.

Of course, these are not the same volumes as when working with gas or diesel gun. But if this moment is critical, then the fan heater should be chosen not with a spiral, but with ceramic plates. The latter heat up to more low temperatures, which greatly eliminates the disadvantages of open spiral heaters. But such models also cost a little more.

How to choose an electric heater gun

Before you go buy a fan heater, you need to clearly understand why you need a heater at all. If air heating is required occasionally and quickly, then an electric heat gun is ideal for such modes. But if the temperature in the room needs to be maintained for a long time and at a constant level, then it is better to look for another option, otherwise the electricity bills will be simply huge.

With the help of a working electric heat gun, the desired temperature can be maintained sufficiently long time, but much more often the device is used for quick and short-term heating

It is also necessary to determine in advance the required power (depending on the cubic capacity of the room) and power supply. Powerful industrial and semi-industrial models require three phase voltage. If the room has only a regular single-phase socket, then the electrical equipment should be selected accordingly.

Criterion #1: heating element

The main thing in an electric heat gun is the fan. But it is standard in all models. It's hard to come up with anything unique here. But it’s worth understanding the heating element in more detail. Both the safety and, to a large extent, the power of the heating device depend on its correct choice.

There are two types of air heating elements in the fan heater:

• spirals made of high-resistance alloys;
• ceramic plates.

The first option heats up to 300–600 0 C, and the second only to 150 0 C. However, due to the smaller area of ​​the heating element, the spirals are somewhat inferior to the plates in terms of efficiency. The heat transfer surface in the first case is significantly smaller than in the second. And the fan “removes” heat from the entire heated area.

If you need an electric fan heater for constant and long-term operation, then it is better to take a closer look at models with ceramic heating plates

The ceramic option is more fireproof, since the temperature of the elements in such a heat gun does not rise too high. And in terms of power output and heating efficiency, models with plates are in no way inferior to their counterparts with a spiral. Moreover, the spiral burns out much more often.

If you disassemble the ceramic plate, then inside it will be the same heating coil. Only it is made of a different alloy and heats up to a lower temperature. At the same time, all the heat it creates is transferred to the ceramics, with which thermal energy is already removed by the air flow from the fan. The plate takes a little longer to heat up than an open spiral, but it will also last longer.

Criterion #2: Hull design

All powerful fan heaters are now available in metal versions with anti-corrosion coating. A plastic body is not acceptable here. In low-power household appliances There may be plastic inserts on the casing, but most often these are rubberized handles and switches that you have to touch with your hands.

The shape of the fan heater body usually looks like an elongated cylinder (like a cannon), but there are also “rectangular” models

All thermal electric guns are divided into:

• stationary;
• mobile (portable).

Stationary models are cheaper and have more power. Portable options are more compact and can be easily turned into in the right direction. They usually have hinges that allow you to adjust the direction of the airflow by rotating the entire gun where you want it to go. However, on sale you can also find an option with rotary dampers that deflect the air stream from the fan to the right/left and up/down.

If a heat gun has a protective dissipative mesh, it must be metal. Here any plastic is categorically unacceptable, since the temperature of the air leaving the fan heater is too high.

Criterion #3: Power

The more power a device has in kilowatts, the faster and larger the room it can heat. But as the power indicators increase, the fan noise also increases. It has to operate at higher speeds, which inevitably leads to an increase in noise in decibels.

According to a simplified scheme, the power of the fan heater is selected at the rate of 1 kW per 10 sq. m. area. But this formula is valid only if the ceiling height does not exceed three meters. According to it, a heat gun can be selected for a garage, cottage or small workshop. For large buildings it is necessary to make more detailed calculations taking into account not the square footage of the area, but the cubic volume of the room.

An accurate calculation of power should be made using a formula that takes into account the volume of the room in cubic meters and the thermal conductivity of the walls, as well as the difference between indoor and outdoor temperatures

In addition to the power (kW), the technical data sheet of a heat gun with a fan also indicates the heat flow or productivity in cubic meters/hour. In most cases, 1 kW accounts for about 100–120 m 3 / h. But some devices have more efficient fans that can pump a larger volume of air. When choosing a model, both of these indicators must be taken into account.

For a cottage or garage it is worth choosing household option with power up to 3 kW. For small spaces this is more than enough. Remember, everything above 5 kW requires a three-phase network.

Criterion #4: additional features

When choosing a heat gun, you should also pay attention to the presence of various additional features, which may include:

1. Splash-proof housing – for fan heaters installed in rooms with high humidity.
2. Built-in air humidifiers and filters.
3. Thermostat for stepwise adjustment of power output.
4. Automatic overheat protection.
5. “Self-shutdown” function when the heating device is tipped over.

Also, some models have a full-fledged block automatic control, which independently maintains the room temperature within the specified parameters. If it is available, the heat gun can be left to work completely unattended: the automation itself will turn the fan heater on/off as needed.

Which manufacturer should you prefer?

In domestic stores heating equipment Electric guns are found both imported and manufactured in Russia. In general, there is not much difference between them. Here you need to focus more on the power of the device. But among the manufacturers there are also recognized leaders, for whose branded fan heaters you will have to overpay a little.

If you need a powerful and durable electric heating gun, then you should pay special attention to models under the brands Ballu (Netherlands) and Master (USA)

Fan heaters are produced by a fairly large number of domestic and foreign companies, but among the main ones we can highlight:

1. Ballu (Dutch brand, but production is established in Russia).
2. Master (USA).
3. Timberk (Sweden).
4. Inforce (Russia).
5. Fubag (Germany).
6. Quattro (Italy).
7. Tropic (Russia).
8. Resanta (Latvia).

Almost all manufacturers offer heat guns in a wide range of heating power and air flow. In the existing range of this equipment, there is always a model for specific needs, you just need to correctly assess the needs.

Taking an electric gun that is too powerful and then turning it off every few minutes so as not to burn yourself is not very smart and costly.

Conclusions and useful video on the topic

How to choose a fan heater:

An example of calculating the power of a heat gun:

The fan heater allows you to almost instantly heat the air in the room to a comfortable temperature. But we must be aware that electric heat guns with a spiral or ceramic plates are intended more for short-term heating. If you need a heater for constant use, then it is better to take a convector or an oil radiator.
