What is an electric heat gun

A heat gun is a heater, in which the heating element is blown with air by a fan. From contact with the heater, the air temperature rises, after which a powerful stream enters the room.

With a capacity of up to 2 kW, the heat gun may have a plastic case. Such a device is called the fan heater and is intended for domestic use. More powerful models equip exclusively with a metal case that looks like a pipe. The latter circumstance makes the device similar to the gun.

Electric heat gun

The body of the electric heat gun of high power is made of steel sheet

When any radiator or convector is not equipped with a fan, the heated air is circulated indoors by convection. This process, firstly, is quite long, and secondly, it is not able to cover a spacious object like a warehouse or hangar: because of local heat losses, slow moving air has time to cool down before it penetrates into remote corners premises.

Heat gun acts differently. Chasing 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.

Components of an electric heat gun

Heat from the gun spreads through the volume of the room thanks to the fan built into it

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

Room heating is not the only function of a heat gun. In fact, it is a large and powerful hair dryer, therefore, it can help in the following:

  • make drying of vegetables or fruits;
  • heat the polymer stretch ceiling so that it can be stretched, as well as roofing material or other roofing roll material to give it elasticity before laying in cold weather;
  • dry the newly applied 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 overheating protection. Many models have a controller and a connector for connecting a remote temperature sensor, thanks to which the heater independently maintains the room temperature set by the user.

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

The advantages of electric guns in comparison with other types

This device benefits in the following:

  1. The design is extremely simple: a piece of wire made of a material with high electrical resistance is used as a heater. In fuel analogues, this role is played by a more difficult burner or nozzle in the manufacture, and in addition, a number of additional elements: in gas - solenoid valve, in diesel - fuel pump, filter and diesel tank.
  2. A simple device provides several benefits at once: low cost, low weight, compact size and simple and inexpensive repair.
  3. There is no exhaust and unpleasant smell.
  4. The noise level is relatively low because only the fan makes noise. In the fuel heat guns, the noise also makes a burner, and in diesel engines, the drive of the fuel pump.
  5. Electric heat gun is safer: the user is not threatened with fuel leakage with subsequent fire or explosion. There is no open flame, which makes the device more fire safe (if the power supply is not overloaded). Also, do not be afraid of poisoning products of combustion of fuel. True, the appliance becomes dangerous in conditions of high humidity, but only in the normal version. If the gun is specifically designed for wet rooms, that is, has a high class of moisture and dust protection, is connected with grounding and through the RCD, then the risk of getting an electric shock is reduced to zero.
  6. Unlike fuel analogs, the electrical unit does not require refilling, therefore, it can operate for as long as desired without user intervention.
  7. Also, maintenance is not required, while the analogue fuel heaters need to be periodically cleaned of soot, and in the diesel heat guns it is necessary to maintain the fuel filter.
  8. The power of the heater can be adjusted in the widest possible range - from zero to maximum. The nozzles and burners of the fuel heat guns are mostly designed for a constant fuel feed rate, respectively, their power can not be reduced without losing the quality of combustion. The relatively recently modulated burners that appear can adjust power, but not as flexibly as electric heaters. In addition, these burners are much more expensive than usual.

The statement about the practicality and convenience of electric heat guns is not a marketing ploy, it is quite reasonable. But it is necessary to take into account the disadvantages:

  1. High cost of electricity. The work of the fuel gun, despite the fact that part of the heat produced is removed along with the smoke, it is still cheaper compared to electric one.
  2. Dependence of power on the capacity of the mains. And the possibilities are in most cases not so great. Household power grid is designed for a maximum load in the range of 7-10 kW. And it's not just the bandwidth of an electrical cable: one of the users who wished to connect in the private house of the electric boiler for 15 kW, I had to pay for the replacement of not only the cable, but also the transformer for substation. The fuel heat cannon in any conditions can “give off to the surface” tens of kilowatts of heat, and it consumes electricity in very modest quantities - only for the fan operation.


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 dozen watts are spent on the fan’s operation), and if consider that the efficiency of electric heaters is almost 100%, then this parameter can be equated to heat output. That is, we can assume that the heat gun, which 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 adjustment 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 m3/ hour, with a power of 3 kW - with a capacity of 300–320 m3/hour.
  4. The power consumed in ventilation mode. Insignificant value. For example, a fan with a capacity of 500 m3/ h consumes only 30 watts of electricity.
  5. Voltage. Models with a capacity of up to 5 kW are designed for connection to a 1-phase network of 220 V. More powerful ones have a 3-phase design, i.e., they operate at 380 V.
  6. Rated current. According to this characteristic, it is possible to determine whether the supply network can withstand the load from the heat gun. If the rated current is not specified, it can be calculated by dividing the power consumption by voltage (I = W / U).
  7. The area of ​​heating with a ceiling height of 2.5 m. This is a rough indicator, which is calculated from the consideration that for heating every 10 square meters. m area at the specified ceiling height requires 1 kW of heat. That is, in the characteristics of a 5 kW heat trap in the column “Heating Area ...” a value of 50 m will be indicated2. However, it should be understood that this is very averaged data, because the value of specific heat loss, namely from it depend on the energy consumption for heating, for different buildings with different volume, glazing and wall material can strongly vary.
  8. The difference in temperature of the air flow at the inlet and outlet in the mode of maximum heat output. This value depends on the power of the heaters. For the most low-power devices, it is 20–400C, and a 18–20 kW gun can heat the air even at 1400WITH.
  9. The maximum allowable time of continuous work.
  10. The minimum duration of the pause between the maximum sessions of continuous work. Usually the maximum time of work and the duration of the pause is indicated as a fraction. For example, the entry “24/2” says that the heat gun can work for 24 hours without stopping, after which it will be necessary to take a break for at least 2 hours.
  11. Class dust moisture protection. Denoted by the letters "IP", followed by two numbers: the first indicates the level of protection against dust penetration, the second - from moisture. In the usual version, the heat guns have a dust and moisture protection class IP.
  12. Electrical protection class. All heat guns with metal casing are class I electrical protection: to the body and other current-carrying parts a ground wire is connected, which is connected to the ground loop through the contacts on the plug and outlet.
  13. Dimensions.
  14. Weight. As already mentioned, electric heat guns are relatively light. Model with a capacity of 2 kW in a plastic case weighs only 0.86 kg. Heater with a metal case with a capacity of 3 kW weighs 9 kg, and models with a capacity of about 20 kW - within 20 kg.

Essential point: if the performance of the fan for any reason turns out to be less calculated, the heat gun will often turn off the overheating protection system.

How to choose an electric heat gun

The choice of heater begins with the selection of its power. Above it was said that the characteristics of the device often indicate the heated area, but these data are purely for reference and can not be trusted. Ideally, you should order a civil engineer or heat engineer for calculating the heat loss of a building that 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. A single formula is used: Q = (V x dT x K) / 860, where Q is the desired heat gun power, kW; V - volume of the room, m3; dT is the difference between the desired temperature of the air in the room and the outside in the coldest period of the year, 0WITH; K - dimensionless coefficient, which is taken in accordance with the design features of the structure and the degree of its insulation for buildings:

  • built with the use of modern energy-saving technologies (all enclosing structures are insulated modern high-performance heat insulators, sealed windows with double-glazed windows are installed): K = 0,6–0,9;
  • built and warmed using traditional technologies and equipped with non-hermetic windows of usual sizes: К = 1–1.9;
  • lungs with walls half a brick, single glazing and a simple roof, possibly with insignificant insulation (household building, etc.): K = 2–2.9;
  • frame with single-layer lining boards or corrugated and without insulation (hangars, warehouses): K = 3-4.

Calculation example

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

  • the heater will be used when the temperature is -50WITH;
  • the room temperature must be maintained at +200WITH;
  • temperature difference inside and outside dT = 20 - (-5) = 250WITH.

The volume of the room will be V = 4 x 5 x 3 = 60 m3.

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

The first option - the pure spiral - is the cheapest, but it has an important drawback: the metal heats up very much, so that dust burns on it, giving off an unpleasant smell.

The heating elements and the ceramic plate do not heat so much, and they are not inferior to the helix in performance, since they have a surface with a much larger area. Dust on them does not burn, 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 the device is supposed to be moved from place to place, you should choose a model with a convenient handle. During operation, the heat guns heat up quite strongly, so that in the absence of a handle, it will be very difficult to move the device.
  2. Well, if the device has a protection against tipping. Usually it has the appearance of a spring-loaded lever protruding from the support sole associated with 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 to the side, the spring will push the lever outwards, as a result of which the switch will be turned to the “off” position.
  3. Overheating protection is also very important, but modern heat guns are equipped with it without fail.
  4. The presence of filters. Models with filters are designed for use in highly dusty areas. It is important to remember to periodically change filters or wash them if reusable products are used.
  5. The presence of a humidifier. If there is no open container with water in the room, then the relative humidity of the air during heating significantly decreases.

This process takes place when using any heater, and 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. The incoming air from the street due to the low temperature 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 up. To eliminate this problem, some models of heat guns are equipped with an air humidifier - a device that quickly saturates the internal air environment with water vapor.

Along the way, we will debunk another myth: none of the electric heaters, regardless of the principle of action, leads to "burning out" or "burning out" of oxygen. The concentration of the latter can be reduced only in the process of burning any fuel. Perhaps the legend of the burning of oxygen due to the fact that the heated air because of its dryness is, as already mentioned, it is unpleasant to breathe.

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

When buying a powerful heavy heat gun, we recommend to pay attention to models with a rotatable working part. With this design to change the direction of air supply will not have to turn the whole gun.

Also convenient devices in which the direction of air flow can be changed with the help of blinds installed in the outlet.

The choice of heat gun for the garage and to give

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

Since the country house is a living space with a permanent stay of people, here you should use a heat gun with heating elements or ceramic plates. They, as mentioned above, do not give the smell of burning dust.

For a garage where the user is relatively short-lived, a gun with a heater in the form of spirals will do. It is good if it is equipped with a tipping protection, since in the garage such incidents are especially dangerous: the direction of hot air after the fall of the gun will change and oil can get into its area of ​​action and petrol. And since these substances are flammable, fire is inevitable.

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

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

Economical heat guns

The high cost of electricity makes buyers look for models that spend this resource as efficiently as possible. These are heat guns equipped with a thermostat. Upon reaching the specified temperature, the device will turn off automatically, respectively, the electricity for heating the room will be spent just as much as needed.

Heat trap without thermostat has to be turned off manually. Not always the user does this in a timely manner, so that the heater, as a rule, even after reaching a comfortable temperature, continues to heat up the room, leading to unnecessary overheating, an increase in heat loss (they, we recall, depend on the temperature difference between the room and the outside) and, accordingly, to the overrun electricity.

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 form, the air passing through the gun has time to heat up to a higher temperature than in the case of a conventional heater.

Electric RexWatt heat gun

Nervous elements in electric heat guns of RexWatt are shaped like a cylinder

This feature, in turn, allows the use of a more productive fan. If air is driven through a conventional 3 kW heat gun in a volume of 300 m3/ h, then through the heater from RexWatt with the same power - 500 m3/ h

Thus, it can be said that the RexWatt heat gun can replace two conventional ones, since it able to circulate and, accordingly, to distribute heat over an area twice as large as normal analogue

However, it should be borne in mind that the heat itself no longer becomes - like with a conventional gun, and with a model from RexWatt it is produced with a power of 3 kW.

A heat gun allows you to do with one device where you would need several radiators or convectors. However, it can act as not only a heater, but also a large powerful hair dryer, which makes these devices very popular. Having carefully studied the above recommendations, you will be able to choose the most suitable model for yourself by managing the funds in the best possible way.
