The text contains an overview of the most popular manufacturers and models of electrical devices.
220V thermal electric gun and its device
High-quality heating of large premises: garages, basements and other spaces will be provided by 220 Volt electric heat guns connected to the network. These devices have a high power rating, thanks to which they are able not only to quickly dry and warm the air, but also to preserve the result for a long time.
An electric gun is a heating equipment with a mobile or stationary design. These devices have an industrial and domestic purpose.
The scope of their application extends to the heating of the following objects:
- storage areas;
- residential premises;
- construction sites;
- production shops, etc.
The assortment of modern stores includes devices designed for connection to a three-phase and two-phase network. Therefore, consumers have the opportunity to buy an electric 220V and 380V heat gun. Networks with two phases are widespread almost everywhere, mainly in urban apartments. Their voltage is 220V. Three-phase communication options are used to feed industrial facilities. In rare cases, houses from the private sector are powered from networks with a voltage of 380V.
Pay attention! Electrical appliances are eco-friendly and safe. Their operation is not accompanied by the release of exhaust gases and toxins. Therefore, it is allowed to use an electric gun to heat residential premises without endangering human health.
The principle of operation of the 220V electric heat gun
The heat gun, which is powered by electricity, has a simple principle of operation. It is a ventilating device equipped with an air heating function. In addition to standard devices, there are guns with infrared heating principle. Heat transfer in them is carried out through the use of IR rays. Electrical devices are designed for rapid heating of small areas. The exception is industrial electric heat guns, which have a high level of power and performance.
Standard products consist of the following components:
- heating element;
- ventilation device;
- temperature controller.
Each of these components performs a specific function. The heating element can be of two types: tubular (TEN) and spiral. The first option is used much more often because it has a longer service life than the spiral. In addition, the heating element burns out less oxygen in the process of heating the room.
The ventilating device generates air flows that pass through the heating element, and the thermostat regulates the room temperature. This component protects the structure from overheating. When the air temperature reaches the required value, the thermostat automatically turns off the power supply.

How to choose a 220V electric heat gun according to technical parameters
The heat gun is installed on any horizontal surface. If necessary, the structure can be moved. The device works almost silently, which does not negatively affect the tenants of the apartment or the working environment in the office. Its performance depends on the technical characteristics of the gun. To decide which heat gun is better, you should study its parameters.
Pay attention! When a new gun is turned on for the first time, a slight odor may appear. This is considered normal. In the course of further operation, it will disappear.
When choosing a heating device, you need to pay attention to the following characteristics:
- power level;
- the presence or absence of the ability to adjust the degrees of power;
- fan performance;
- the speed at which the heated airflow exits the structure;
- outlet air temperature;
- voltage in the electrical network;
- number of operating modes;
- fire safety level;
- dimensions of the device;
- degree of mobility;
- decorative qualities;
- noise exposure level;
- additional functionality.
How to choose an electric heat gun: calculation of optimal power
To decide which heat gun to buy for a garage, you should find out what power indicator the design should have. This takes into account the size of the room. For example, if the dimensions of the garage are 4×6 m, by simple calculations you can find the desired indicator.
To begin with, the area of the room is calculated. In this case, it is equal to 24 m2. Experts recommend adding a small margin of 20% of this value to the required power indicator. The result is: 2,4×1,2 = 2.88 kW. So, for the specified room, the minimum power of the heat gun is 3 kW.
There is another technique. It allows you to get a more accurate result. It is desirable to use this option to calculate the power of a thermal electric gun for a house. In this case, the formula is based not on the area of the room, but on the degree of thermal conductivity of the walls and the volume of the room.
First you need to get the indicators necessary for calculations:
Table of thermal conductivity of materials:
|Wall material||Coefficient of thermal conductivity|
|Surfaces with high-quality thermal insulation||06,-1|
|Brick double-row masonry or wall with an average level of thermal insulation||1-2|
|Surfaces with poor insulation||2-3|
|Walls made of boards or profiled sheet (hangars)||3-4|
To understand which heat gun to choose, it is enough to perform the necessary calculations, considering the same garage as an example. The volume of the room: 4x6x3 = 72 m3. If the temperature outside the building is -20 ° C, and inside it is 15 ° C, then the difference will be 35 °. Taking the insulation coefficient 1, we get: 35x72x1 = 2520 kcal / hour. 1 kW contains 860 kcal.
The result should be divided by 860 kcal and the result is 2.93 kW. If we take into account that the power of the gun is taken with a margin, then a device with 3.5 kW will be required for such a room.
Useful advice! You should not buy a gun with a high power rating for your home. Such devices drive away a strong air flow, so they will create a lot of noise during operation.
How to choose a heat gun: voltage and duration of operation
The operating voltage is another characteristic that requires attention. There are units on the market whose power exceeds 20 kW. For the operation of such structures, a three-phase electrical network is required, where the voltage is 380V. If you are going to buy exactly such a heat gun for heating, you definitely need to take care of replacing the wiring with a more powerful option.
Structures whose power does not exceed 7 kW can be powered from a mains voltage of 220V, provided that the wire section is designed for such loads. Before connecting the heat gun, it is advisable to calculate the optimal cable cross-section taking into account power and current. Thanks to this, problems with wiring and short circuit can be avoided.
When choosing a heating device, it is also necessary to pay attention to the duration of uninterrupted operation. The device is not able to work for a long time without switching off, otherwise it will fail very quickly. For this reason, manufacturers of heat guns are marked “24/1” or “24/2” on the body. This means that the device is capable of working around the clock with a break of 1-2 hours, depending on the specified mark.
There are other technical characteristics that affect the operation. When choosing a device, it is necessary to pay attention to the level of noise exposure and the temperature range within which the gun is able to effectively carry out its work.
Pay attention! The minimum operating temperature range for a high-quality device is 5-40 ° C.

I can’t say that a heat gun is a basic necessity, but such a thing will not be superfluous in the house. My husband periodically uses it in his garage, although we took it for a bath. When it’s freezing outside, you can’t do without pre-heating the premises. Without this gun, it took almost the whole day to kindle the bathhouse, a couple of hours is enough with the device.”
Elena Prodayvoda, Moscow
“Using a Resanta welding machine in my garage. It’s cold to work in winter, so I decided to buy myself a heat gun from the same company. A little disappointed. I have a good, high-quality welding machine. I didn’t think it would be any different with a gun. It is, of course, small and very quiet, but in fact the room heats poorly, eats a lot of electricity. I don’t know if the heat guns themselves are nothing, or if the model should have been taken more powerful. In general, I have it almost idle. I occasionally use it to start the car engine.”

How to make an electric heat gun with your own hands
An electric device for heating the room can be made independently. The simplest design consists of a heating element, a fan and an electric motor. All this is hidden in a metal case. The most difficult stage is the development of an electrical circuit diagram. To avoid mistakes, you can use ready-made options that can be found on the Internet. Most often in the circuit, the thermostats and the toggle switch are connected in series. The circuit is closed on an electric motor and a heating element.
Assembly technology of a simple structure with a heating element
As a housing for a future gun, you can take a large-diameter pipe trim. Metal or asbestos-cement products are suitable for this. The size of the case should be selected taking into account the span of the fan blades, which should overlap one of the end sides of the device. Ready-made heating element can be purchased in the store or removed from an old boiler or stove. To work, you will need a circuit breaker, a cable with three cores, a safety automatic, bolts.
Useful advice! For the manufacture of the housing, you can also use improvised means, for example, a small metal tank, an old saucepan, a galvanized bucket. The main thing is that the structure has thick walls.
To begin with, the required power of the device is determined. To do this, you can use the formula that was considered earlier. After that, you need to check whether the wiring in the room will withstand such a load.
Next, the body part is manufactured. If there is no metal pipe at hand, you can take a steel sheet. It bends in the desired position and is fixed with rivets, hoops or by welding. If a bucket or pan is intended to be used, the bottom should be sawed off. The result should be a rectangular or cylindrical body.
Then the resistance of the heating element is compared with the calculated data. If necessary, 1-2 additional elements can be added to the circuit, which are connected in series. To increase the power, the TEN is shortened. An electric motor and a fan are fixed from one end. The blades should cover the lumen as much as possible, but nothing should interfere with rotational movements. The connection of the network wires is carried out through a fuse. A switch is also installed here.
The TENG should be fixed inside the case, preferably in the center. Plates made of refractory metals or rivets can be used as fasteners. The heating element must be located at a sufficient distance from the fan, otherwise the motor will be subjected to overheating. The wires should be brought out and connected to the mains through another fuse.
The design is completely ready. Before starting its operation, it is necessary to check the quality of insulation on all connections and perform a trial test. If the assembly is done correctly, a fan will start from one end, and heated air will come out from the second. Such a gun is very easy to manufacture and requires only time and minimal knowledge in electrics, although it will be much safer to purchase a ready-made device in a store.
