With the onset of cold weather, electrical appliances are most often used to heat the room. The modern market offers a huge selection of fan heaters, oil coolers, convectors, etc. Now electric heat guns are rapidly gaining popularity, allowing you to warm the air in any room in a matter of minutes.
Design features of a thermal electric gun
Depending on the model, electric heat guns can operate on 220 or 380 volt AC power. Powerful electrical appliances are used in production. For domestic use, models operating from a 220 volt network are used.
To get to know the electric heat gun better, let’s look at its device:
- All elements of the thermal electrical appliance are located in a metal case. To move the gun is equipped with a comfortable handle. A metal stand is fixed under the case from below.
- An electric heating element is installed inside the case, which acts as a heater. It generates heat after applying a voltage of 220 or 380 volts to it. The manufacturer uses tubular models. Such heating elements last longer and are fireproof.
- A reflector is located around the heater. It does not allow the body to overheat and directs heat to the outlet of the electric gun – the nozzle.
- In front of the heater, that is, on the back of the heat gun, there is a fan. It is driven by an electric motor powered by 220 volts.
- Any model of a thermal electric gun is equipped with protection against overheating. The sensor turns off the voltage supply to the heating element when the temperature of the device case approaches a critical level. The automatic operation of the heat gun is controlled by a thermostat. It allows you to maintain the set temperature.
- Control keys are installed on the body of the electric gun. They usually have lights on them.
Electric heat guns work on the principle of a familiar fan heater. That is, they take in cold air and give out warm air. The fan installed in front of the heating element creates an air flow during the rotation of the blades. Passing through the heating element of the electric gun, the air takes heat, after which it enters the directed point of the room through the nozzle.
The main advantage of the electric gun over analogues running on gas and diesel fuel is environmental friendliness. The electrical appliance practically does not burn oxygen during operation, and there are no emissions of harmful substances along with combustion products. Owners of diesel heaters know how hard it is to start them in the cold to warm up a garage or warehouse. The electric gun will turn on without any problems at any negative temperature, the main thing is that there is a voltage of 220 or 380 volts. But if there is no connection to the mains nearby, it will not be possible to use a thermal device, and this is its only minus.
Scope of electric heat guns
Due to good technical characteristics, electric guns are widely used in many areas of human life:
- With the onset of cold weather for an apartment, a heat gun is the best source of heat until the central heating is working. The device can be taken with you to the country house, installed in a glazed gazebo, used to heat an office, etc. In general, a thermal electric gun can be used in any room where people are.
- For household purposes, the use of an electric heater helps to dry the cellar or pantry, warm the car in severe frost, and maintain the optimum temperature in the greenhouse.
- An electric gun is indispensable when performing construction and repair work. The device is used to heat the canvas when installing a stretch ceiling, drying plaster, etc.
- In industry, powerful three-phase thermal units are most often used for heating large workshops, and they are also used to perform certain technological work.
An electric heat gun is able to work under almost any conditions, the main thing is to use it carefully inside damp rooms. It is also important to pay attention to the wiring. With a weak cross-section of the cable, it will overheat, followed by burnout.

Rules for choosing an electric heat gun
According to many people, a good heater is one that consumes little electricity and heats well. In a way, they are right. But how to choose the best heat guns among a large number of models? It should be noted right away that all thermal electric guns operating from a 220 V network consume little energy. And this is not due to the power of the heating element. The fact is that the heater turns on for a short time. When the maximum threshold of the set temperature is reached, the heating element is turned off, and only the fan, which consumes little electricity, remains in operation.
However, the consumer must clearly understand what criteria should be used to choose an electrical appliance:
- First, a person needs to decide why he buys a thermal electric gun, that is, what tasks the device will cope with. If this is the periodic heating of a small room, then it is reasonable to give preference to a low-powered gun. For repair work or heating a greenhouse, it is worth buying more professional models.
- The second important factor is the features of the room where the heat gun will work. The area, configuration, quality of thermal insulation of building elements are taken into account. These parameters determine how much power and how many electric guns you need to buy.
- When choosing an electrical appliance by power, you must first test the network. First, determine what voltage is supplied: 220 or 380 volts. Secondly, you need to make sure that the cross section of the wires is sufficient for such a load.
- Parameters such as the mass and size of the heat gun are not very important, but the comfort of working with an electrical appliance depends on them.
- With regards to the price, it should be noted: not all good things are expensive. Often sellers wind up the price of goods because of the brand name. When choosing a thermal electric gun, they are guided by the technical characteristics of the device, and then they are already determined by the manufacturer and price.
Almost all models of heat guns are designed for operation up to 10 years under the conditions recommended by the manufacturer. That is why you should carefully approach the choice of electrical appliances.

IR heat guns
In popularity, electric models compete with infrared heat guns operating on the principle of radiation. IR devices do not have a built-in fan, as there is no need to create an air flow. Infrared rays heat the surface of any object, and it, in turn, gives off heat to the air.
However, it must be taken into account that only those objects that are in the radiation area receive heat. This determines the specifics of the use of IR heat guns. The device is relevant where spot heating is required.
Which is better to buy: an electric gun or a fan heater
The operation of an electric gun and a fan heater is almost the same. Both electrical appliances with the help of a fan drive the air flow through the heating element. An inexperienced person takes what is cheaper – a fan heater. However, you need to know that these devices, similar in functionality, have significant differences.
So, any of these devices are bought to heat a specific object. Here you need to take into account the volume of heated air. The power of fan heaters is limited to 1-2 kW, and the electric gun is capable of delivering more than 4 kW per hour. Here it is worth considering that to heat a large hangar it is better to buy one heat gun than ten fan heaters.
But in the apartment it is better to give preference to a fan heater. They are more compact, more beautiful, and the power of 1-2 kW is enough to heat one room. Expensive models of fan heaters are equipped with ceramic heaters that do not burn oxygen during operation. Inside cheap devices are ordinary spirals. It is undesirable to use them in a residential area, especially if the humidity is very high.
Almost all fan heaters have the function of turning off the heating element. In an apartment, such a device can be used in summer instead of a fan to cool the air. Now manufacturers have begun to supply thermal electric guns with this function. Devices can even have a three-stage adjustment of the temperature of the supplied air: cold, warm, hot.
